Definitions
- the invention relates to building blocks, such as used in construction of walls and other structures where blocks are stacked in rows or layers.
- Adjacent blocks are typically cemented, as by using mortar, one to another laterally as well as in stacked rows. These blocks tend to be relatively heavy, and generally have poor insulative ability. The blocks may also be relatively porous, allowing moisture to seep through and into the construct. Insulated block material made today typically may use complex arrangements of concrete blocks with insulating material inserts installed, oftentimes in the field.
- the concept with an insulative block like a CMU, is to minimize heat transfer between one side of the block, as in a wall structure, to the other side. For instance, this may be between an outside or exterior of a wall structure, and the interior defined by the wall structure. Sometimes this is attempted to be accomplished by minimizing the cross section of the block (its width or thickness in the wall structure), and lengthening the thermally conductive paths formed by the concrete connections of the block itself.
- the present invention in one aspect provides a substantially insulated concrete block, or CMU, which has an insulative core to which a cladding, such as concrete, is applied, as forming the lateral or side faces of the CMU.
- the insulative core may be of many types, such as foamed styrene, Styrofoam, or the like. This yields a relatively moisture resistant element to the block with thermal insulating properties.
- the cladding may be masonry, ceramic, metal, concrete and so forth.
- the cladding is in the form of concrete which is applied to the core in a molding or pouring operation, as along the lateral sides of the core.
- the core in this version would have elements to which the concrete would mold, surround and adhere to in order to fix the concrete to the core.
- These anchor elements may be in the form of wires which extend outwardly from the core and are fixed within the core, thus forming anchors for the concrete when it has set.
- the wires may, for instance, be in the form of T-bars, but can take many shapes.
- the material of the anchors may be metal, plastic or other material which will serve to hold the concrete to the core, and thereby form a relatively stable and sturdy structural unit, such as one that can be stacked into a wall structure.
- anchor elements are considered expansively herein, and may further be indentations, grooves or other shapes formed into the core, into which the concrete or other fluent material may intrude and adhere to the core.
- Attachment of the cladding could be through adhesive means, such as chemical adhesion or mechanical adhesion (e.g., bonding or gluing).
- a building block for construction as for housing structures and walls thereof, has a core member which is of thermal insulative material formed in an integral piece.
- the core member has a top, bottom, ends and lateral sides.
- a cladding is fixed to at least the lateral sides of the core.
- the cladding is of a masonry material, such as concrete.
- the core member and the cladding form a rigid block capable of supporting loads in a building structure made up of a plurality of the blocks stacked one upon another.
- the insulative core member may further form part of the load supporting structure of the CMU itself.
- At least one aperture extends through the core member between the top and bottom.
- a plurality of anchor elements extend from the core member lateral sides. The anchor elements provide attachments which become integrated with the masonry material in the course of fixing the cladding.
- the ends of the inventive block may have an end structure which is keyed, such that a first end of one block fits with a second end of another block in an engagement which is at least partially overlapping between the first and second ends.
- the top and bottom may have a structure which is also keyed, such that a top of one block has a shape that fits with a complementary shape of a bottom of another block.
- the sides of the core may also have a feature to promote attachment of the masonry cladding.
- the anchor element may be a dovetail slot formed in each lateral side of the core, such that masonry material in initial fluent form will enter into and solidify within each slot to affix the cladding.
- the core member has a channel formed in its top surface. This channel extends from a point on the top surface toward a lateral side, such as to a point on the lateral side below the top surface. This channel thereby provides a path for water to exit from within the block in the building structure.
- the anchor elements may take many forms, such as bars, wires, plates and other members, which preferably extend outwardly from the core member.
- these bars may have an elongated part embedded within the core member, with t-shaped portions on either end of the elongated part extending outwardly from the core member.
- the anchor elements could be fibrous material, such as metal or plastic filaments, which is part of the core and extends outwardly from the core sides, like hairs or a mesh.
- the block has a core member that is substantially solid except for an aperture extending through the core member (e.g., top to bottom) and at least one of the top and bottom define a surface which slopes downwardly to the aperture to thereby direct water that may be present in the building structure to the aperture.
- the aperture thus functions as a drain for the core/block.
- the building block may further provide that the core member has a hollow between the top and bottom.
- the hollow is capable of receiving a rebar member therein extending through a plurality of the blocks in a building structure.
- the core member may additionally include a web element internal to the core and extending within the hollow. This web element engages with and positions the rebar in use in the building structure.

- the core member has a top, bottom, ends and lateral sides, with a cladding fixed to at least the lateral sides.
- the cladding is of a masonry material.
- a plurality of anchor elements are formed in or otherwise provided in the core member lateral sides. The anchor elements provide attachments which become integrated with the masonry material in the course of fixing the cladding.
- Each end of the block has a channel formed therein between said top and bottom.
- Such a core member with its cladding forms a rigid block capable of supporting loads in a building structure made up of a plurality of the blocks stacked one upon another.
- the apertures are generally centered in each block, such that when the blocks are placed in rows one upon another, with blocks in each row being offset from an adjacent row by a half-block length, the apertures align with the end channels in vertical arrangement, so as to provide a vertical pathway through building structure.
- the foregoing embodiment may further include a plug member having a hole extending between a plug top and bottom.
- the plug fits in a space formed by channels of abutting ends of adjacent blocks in a row.
- the foregoing building structure may utilize blocks wherein the top of the core member defines a top surface having a slope toward the aperture to direct water that may be present in the building structure towards the aperture, and thereby through the vertical pathway and out of the building structure. There may also be a part forming a drain spout which extends generally laterally outboard from the bottom of selected block, to direct water out of the building structure.
- the cladding, or slabs or sidepieces may be precast, precut or preformed. They can then be attached to the core in a molding operation, or attached to the core using conventional bonding material, such as adhesive (resins, elastomeric adhesives, etc.).

That is, the end channel 53 is defined by vertical ribs or columns 57 at each end of the CMU 50 . The ribs 57 extend vertically in the same plane. Therefore, when blocks 50 are placed end to end, the respective ribs 57 abut, creating a space open top to bottom by the respective channels 53 .

Abstract
An innovative masonry block, such as a CMU, has a core of insulative material with masonry cladding, such as concrete, on lateral sides, and anchor elements, such as rigid bar members, may extend from the core to hold the cladding to the core. The core may also include a drain aperture extending from top to bottom, as well as a sloped top surface that serves to direct water to the drain. A plurality of such blocks can make a wall or other building structure having a pathway for water to travel through and out of the stacked blocks.
Description
- This application claims priority to U.S. Provisional Application No. 61/753,744, filed Jan. 17, 2013, the contents of which are hereby incorporated by reference in their entirety.
- The invention relates to building blocks, such as used in construction of walls and other structures where blocks are stacked in rows or layers.
- In construction certain kinds of buildings, such as walls of the building, concrete or other masonry blocks are often employed. Adjacent blocks are typically cemented, as by using mortar, one to another laterally as well as in stacked rows. These blocks tend to be relatively heavy, and generally have poor insulative ability. The blocks may also be relatively porous, allowing moisture to seep through and into the construct. Insulated block material made today typically may use complex arrangements of concrete blocks with insulating material inserts installed, oftentimes in the field. The concept with an insulative block, like a CMU, is to minimize heat transfer between one side of the block, as in a wall structure, to the other side. For instance, this may be between an outside or exterior of a wall structure, and the interior defined by the wall structure. Sometimes this is attempted to be accomplished by minimizing the cross section of the block (its width or thickness in the wall structure), and lengthening the thermally conductive paths formed by the concrete connections of the block itself.
- The present invention in one aspect provides a substantially insulated concrete block, or CMU, which has an insulative core to which a cladding, such as concrete, is applied, as forming the lateral or side faces of the CMU. The insulative core may be of many types, such as foamed styrene, Styrofoam, or the like. This yields a relatively moisture resistant element to the block with thermal insulating properties. The cladding may be masonry, ceramic, metal, concrete and so forth.
- In one embodiment, the cladding is in the form of concrete which is applied to the core in a molding or pouring operation, as along the lateral sides of the core. The core in this version would have elements to which the concrete would mold, surround and adhere to in order to fix the concrete to the core. These anchor elements may be in the form of wires which extend outwardly from the core and are fixed within the core, thus forming anchors for the concrete when it has set. The wires may, for instance, be in the form of T-bars, but can take many shapes. The material of the anchors may be metal, plastic or other material which will serve to hold the concrete to the core, and thereby form a relatively stable and sturdy structural unit, such as one that can be stacked into a wall structure.
- Such anchor elements are considered expansively herein, and may further be indentations, grooves or other shapes formed into the core, into which the concrete or other fluent material may intrude and adhere to the core. Attachment of the cladding could be through adhesive means, such as chemical adhesion or mechanical adhesion (e.g., bonding or gluing).
- In an aspect of the invention, a building block for construction, as for housing structures and walls thereof, has a core member which is of thermal insulative material formed in an integral piece. The core member has a top, bottom, ends and lateral sides.
- A cladding is fixed to at least the lateral sides of the core. The cladding is of a masonry material, such as concrete. The core member and the cladding form a rigid block capable of supporting loads in a building structure made up of a plurality of the blocks stacked one upon another. The insulative core member may further form part of the load supporting structure of the CMU itself.
- In an embodiment, at least one aperture extends through the core member between the top and bottom. A plurality of anchor elements extend from the core member lateral sides. The anchor elements provide attachments which become integrated with the masonry material in the course of fixing the cladding.
- The ends of the inventive block may have an end structure which is keyed, such that a first end of one block fits with a second end of another block in an engagement which is at least partially overlapping between the first and second ends. This could be a tongue-and-groove presentation at each end, and in one form there are multiple parallel tongues which fit into multiple parallel grooves. Further, the top and bottom may have a structure which is also keyed, such that a top of one block has a shape that fits with a complementary shape of a bottom of another block.
- The sides of the core may also have a feature to promote attachment of the masonry cladding. For instance the anchor element may be a dovetail slot formed in each lateral side of the core, such that masonry material in initial fluent form will enter into and solidify within each slot to affix the cladding.
- In an aspect of the invention, the core member has a channel formed in its top surface. This channel extends from a point on the top surface toward a lateral side, such as to a point on the lateral side below the top surface. This channel thereby provides a path for water to exit from within the block in the building structure.
- The anchor elements may take many forms, such as bars, wires, plates and other members, which preferably extend outwardly from the core member. In one embodiment, these bars may have an elongated part embedded within the core member, with t-shaped portions on either end of the elongated part extending outwardly from the core member. The anchor elements could be fibrous material, such as metal or plastic filaments, which is part of the core and extends outwardly from the core sides, like hairs or a mesh.
- In still another aspect, the block has a core member that is substantially solid except for an aperture extending through the core member (e.g., top to bottom) and at least one of the top and bottom define a surface which slopes downwardly to the aperture to thereby direct water that may be present in the building structure to the aperture. The aperture thus functions as a drain for the core/block.
- The building block may further provide that the core member has a hollow between the top and bottom. The hollow is capable of receiving a rebar member therein extending through a plurality of the blocks in a building structure. In such an embodiment, the core member may additionally include a web element internal to the core and extending within the hollow. This web element engages with and positions the rebar in use in the building structure.
- An aspect of the invention is a building structure formed of a plurality of masonry elements which are stacked one upon another, as for housing structures and walls thereof. A plurality of building blocks is provided, each building block having a core member which is of thermal insulative material formed in an integral piece. The core member has a top, bottom, ends and lateral sides, with a cladding fixed to at least the lateral sides. The cladding is of a masonry material. Preferably, a plurality of anchor elements are formed in or otherwise provided in the core member lateral sides. The anchor elements provide attachments which become integrated with the masonry material in the course of fixing the cladding. There may be at least one aperture extending through the core member between the top and bottom. Each end of the block has a channel formed therein between said top and bottom.
- Such a core member with its cladding forms a rigid block capable of supporting loads in a building structure made up of a plurality of the blocks stacked one upon another. The apertures are generally centered in each block, such that when the blocks are placed in rows one upon another, with blocks in each row being offset from an adjacent row by a half-block length, the apertures align with the end channels in vertical arrangement, so as to provide a vertical pathway through building structure.
- The foregoing embodiment may further include a plug member having a hole extending between a plug top and bottom. The plug fits in a space formed by channels of abutting ends of adjacent blocks in a row.
- The foregoing building structure may utilize blocks wherein the top of the core member defines a top surface having a slope toward the aperture to direct water that may be present in the building structure towards the aperture, and thereby through the vertical pathway and out of the building structure. There may also be a part forming a drain spout which extends generally laterally outboard from the bottom of selected block, to direct water out of the building structure.
- Further, the cladding, or slabs or sidepieces, may be precast, precut or preformed. They can then be attached to the core in a molding operation, or attached to the core using conventional bonding material, such as adhesive (resins, elastomeric adhesives, etc.).

FIG. 11 is a side view of a portion of a wall built up with blocks made in accordance with an aspect of the invention; and -
FIG. 12 is a perspective view of another type of anchor element and related side masonry piece to which it would attach. - Referring initially to
FIG. 1 , a first embodiment of a CMU made in accordance with aspects of this invention is shown at 10.CMU 10 has aninsulative core 12 withmasonry cladding 14 on its elongate lateral sides. Here, thecladding 14 is made of concrete, which has been molded to the sides of thecore 12. For example, the core would be placed in a mold, and the liquid/viscous concrete then admitted to the mold, so as to adhere to the sides of the core, and then set into a rigid integrated portion of the CMU. As has been already noted, and will be further discussed, the cladding forms the primary load-bearing part of the block, and may be made of other masonry materials, as well as other materials. The core material is intended to be insulative, such as glass foam, polystyrene, polyurethane, asphaltic foam, and the like. - The core material may further form part of the CMU support structure, contributing to the strength of the CMU by flexing, torsional and tensile forces, for instance. A core material having a tensile strength of about 30 psi, or more, is considered particularly advantageous.
- In order to better attach and integrate the
cladding 14 in this embodiment, the core has some notches orindentations 16 formed in the lateral sides of thecore 12. Thesenotches 16 may be optional. Referring toFIG. 2 , more significant areelements 18 which form anchors extending outwardly from the core. Here, theanchor elements 18 are T-bars, (also seeFIG. 3 ), formed from rigid wire stock. The T-bars 18 extend through the core, with an elongated bar 19 embedded in the core having portions protruding laterally outwardly from the core side, and terminating in across-piece 20.Parts 19 and 20 may be welded. Alternatively, the anchor element could be made as an L, with the crosspiece simply bent from the stock end. Note further that the T-bars need not extend completely through thecore 12, but could just extend partway therein, just so that they are sufficiently embedded to perform their function as anchors. - Variations on the anchor element are shown in
FIG. 3 d which is adouble T element 22, andFIG. 3 b which is a wire X 24 having an L shaped terminus for the stock.FIG. 3 a shows an element having solid planar parts, with a central web 27 and endwebs 28. -
FIG. 12 shows another variation on an anchor element. Thisanchor element 110 has an elongatedcentral bar 112, withend plates 114 extending orthogonal to the bar at each end thereof Theanchor element 110 would be embedded within a core as previously described. The end plates would be on the outside lateral sides of the core, with the back of the end plate either flush with the core side or perhaps slightly embedded therein. - Instead of a masonry cladding formed from an initially viscous material, such as concrete, which would set (harden) about the
anchor 110, a finished masonry element is provided in the form of aplatelike side piece 116. This would facilitate the use of masonry materials that do not need to be poured about the core in situ, such as the use of cut stone, and facades of many different textures and surface features. Moreover, “masonry materials” is used expansively in this disclosure. It is conceivable that a wood facade might form the cladding, or metal, plastic and so forth. - In this embodiment, the
sidepiece 116 has a well 118 formed therein, which is sized to receive anend plate 114 of ananchor element 110 therein. The depth of the well 118 is such that the inner (inboard) face of thesidepiece 116 will be flush with the core side. An adhesive would be used to affix theend plate 114 in the well of thesidepiece 116. Adhesive could be further used on other parts of the inner face of the sidepiece and/or core side to affix the core andsidepiece 116 together. Note that the well 118 might be eliminated in some embodiments, with the core andsidepiece 116 being connected with theend plate 114 flush with the side of the core. - It may be further understood that a core of the type considered by this invention might be formed in two (or perhaps more) pieces, and then joined together, as also by bonding, as by welding, adhesively securing the two core parts, and so forth. This could simplify embedding anchor elements, if top and bottom halves of a core were provided; an elongated anchor part, such as described with the T-bars or the
elongated bar 112 of the foregoinganchor element 110, could then be sandwiched between the two halves, thereby eliminating a molding step involving the anchor element. - Returning to
FIGS. 1 and 2 , thecore 12 hasvoids top surface 32 through to acore bottom surface 34. Top and bottom may be considered relative, as these may be mirror images of each other, or these surfaces may be uniquely designed so as to only mate with the top surface upwardly, for instance. Upwardly is considered with regard to how the CMU would be oriented in a wall or other building structure. - On at least the
top surface 32 is a ramp-like orsloping part 36, which extends at an angle down from the top surface to the lateral side. Thissloping part 36 forms an exit in the form of a weep vent, for water that may accumulate in the wall structure. - The ends of the core 12 are also provided with mating structure in one aspect of this invention, so that two CMU's placed end to end in a row or layer will interfit. In this embodiment, a kind of tongue-and-groove arrangement is provided. One end of the
core 12 has a protrudingtongue part 40, which fits within a complementary groove orcavity 42. A series ofparallel grooves 44 are also formed on an end, forming structure that would mate with complementary structure formed on the opposite end of the core. - Turning to
FIG. 4 , anotherembodiment 50 of a CMU is shown. It is formed similarly to that described with respect to thefirst embodiment 10, with some variation in thelateral notches 16 used to attach the concrete cladding and end structure of the core; here, the end structure has vertical channels 53 which are relatively centered along the long axis of theCMU 50. In thisembodiment 50,core 52 has a single generallycentralized void 54, which can form a drain for the block, and thereby for the building structure in which a plurality of theseblocks 50 would be used. - Top surface 56 of the
core 52 has a sloping structure, so that the surface 56 will direct water falling therein to thedrain void 54. -
FIG. 4 a shows a drain ordrain cap 60, which is here in the form of an L-shaped conduit. The drain may be made of a rigid plastic, sheet metal, or the like. Part of the L would be sized to fit within the bottom of adrain void 54, as in a lower run of a wall structure, with the other part of the conduit extending beyond the wall to vent water. -
FIG. 4 b shows a fibrousmat sheet material 65, which might be sized so as to cover the top surface 56. The mat would allow water to pass therethrough, but prevent most debris from getting into the drain. Thismat 65 could also be insulative material. - As will be shown with respect to a wall structure in
FIG. 11 , blocks such as those of the type ofCMU 50 can be organized so as to provide a continuous drain path for water throughout the wall. This is accomplished here by offsetting theblocks 50 by a half-length from one layer to another. Central drains 54 will thereby align with end channels 53, with end channels 53 ofadjacent blocks 50 abutting to create a single passageway. That is, the end channel 53 is defined by vertical ribs orcolumns 57 at each end of theCMU 50. Theribs 57 extend vertically in the same plane. Therefore, when blocks 50 are placed end to end, therespective ribs 57 abut, creating a space open top to bottom by the respective channels 53. -
FIG. 8 shows a modified arrangement of CMU blocks 50; theseblocks 50 have been slightly modified themselves, to emphasize a wider passageway that would be otherwise presented by abutting blocks. This embodiment utilizes aplug member 66 between the abutting ends of theblocks 50 in a row.Plug 66 has a drain 67 extending between a top and bottom of the plug. It would be sized to fit within the space between theabutting ribs 57. Theplug 66 could be slightly tapered so as to slope inwardly top to bottom. As depicted inFIG. 9 , the bottom of theplug 66 can be provided with a notched structure for better drainage capability, here with crossinggrooves 68. - Referring now to
FIG. 5 , another embodiment is shown, here of aCMU 70. ThisCMU 70 has aninsulative core 71, that has adrain void 54 which is offset to one side of the top surface 72 of thisCMU 70. Top surface 72 slopes toward thedrain 54 in similar fashion to that described with relation toCMU 50. Alarge void 74 is provided somewhat offset on the other side of the top surface 72. This large void may be useful in providing further reinforcement in a building structure, as will be described momentarily with respect to the embodiment ofFIG. 6 . - Note that the
core 71 ofCMU 70 does not extend to the ends of the CMU in this embodiment. Theconcrete cladding 77 is formed to extend beyond the core ends 78. The core ends havecorner extensions 79, and the cladding surrounds theseextensions 79, extending slightly inboard relative to the core ends. These ends 83 of each cladding side thus surround and embrace theextensions 79. There is also a dovetail engagement between the cladding and the core, with complementary portions indicated at 80 and 81. - Looking at
FIG. 6 , there is shown an embodiment much like that ofFIG. 5 . This CMU 85, however, does not utilize a drain void, but instead has a sloping top surface 87 which slopes away from thelarge void 74 toward theend 78 of the core. The CMU 85 is furthermore provided with ananchor element 89, which is similar to that described as element 24 inFIG. 3 b. There may be more than one such anchor element near the top and bottom of the CMU 85. Thisanchor element 89 extends within thelarge void 74, and provides a support and centering for positioning of arebar 90. Therebar 90 may rest in the nook, orcrotch 92, formed by the cross-pieces of theanchor element 89. Use of such rebar as additional reinforcement and stabilizing in building structures using CMU's is well known. Typically, concrete (cement) would also be poured into the CMU voids through which the rebar extends. -
FIG. 7 is an embodiment very much identical to that ofFIG. 6 . However, this CMU 95 has a large void 96 in the core 71 which does not have its sides parallel with those of the CMU. Here, the generally square cross-section void 96 has been rotated about 45 degrees on its axis. This placescorners 97 near the sides of the core 71, rather than the sides extending adjacent a length of the core (as inFIG. 6 ). The insulative ability of the CMU 95 may thereby be improved, through this further reduction in the heat-transfer pathway through the CMU. -
FIG. 10 shows yet another version of an embodiment of a core for an inventive CMU. Thiscore 100 hasanchor elements 104 extending through and out of thecore 100. The ends of thecore 100 have ribs orcolumns 57 as previously described. The lateral sides of the core havevertical channels 105 defined therein, as well as horizontally crossingchannels 106. This creates a substantial surface detail for the lateral sides into which the masonry material, such as cement, can embed and attach, to thereby form the lateral cladding for the CMU. -
FIG. 10 a illustrates a form of mold piece which could be used to create thedrain 54. This is an elongated mold element having ashaft 109 and anend part 110. This would be put in position in the mold being used to make the core, and then removed. - While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques that fall within the spirit and scope of the invention.
