Serial No. 380,804.

This invention relates to building construction and particularly to a building unit and a structure formed therefrom whereby a high 1y improved building may be made at relatively low cost.

The value of cork as an insulating material is well known. A'wall of cork alone would be ideal from the standpoint of thermal and sound insulation. However, provision must be made for supporting the weight of the building and for protecting the cork from injury. It has heretofore been customary to secure the cork to the inside or outside of studding in the case of wood framed structure, on the inside or outside of a steel frame after the entire steel is erected, or to the inside of a tile or brick wall where it was desired to insulate the building walls. I provide a building made of units comprising metal frames which form the supporting skeleton of the building, these frames containing panfact that the insulating els of a suitable insulating material such as' cork board. The panels are inserted before erection. The units may be made up in standard sizes at a factoryat relatively low cost, shipped in a relatively small space, and readily assembled by semi-skilled labor into the desired structure, and are easy to handle on account of their light weight.

The frames are preferably made of steel channels weldedtogether at the corners so that each frame is in itself a very rigid structure. The channels are preferably deeper than the insulating panels are thick, the panels being placed adjacent the flanges of the channels at one side of the unit and being held in place by clips or the like within the frame. The units are preferably assembled in such manner that the panel side is outermost. This gives recesses in each unit when the assembled structure is viewed from the inside and these recesses provide convenient places for pipes, wiring, etc.

The problem of uniting the several' units is also materially simplified by reason of the anels are of less depth than the units. guch construction leaves parts of the channel webs exposed and provision is made for uniting such web portions.

At the corner of a building the units forming one wall are placed against the edges of the adjacent units in the other wall, and by,

reason of the fact that the insulating panels are outermost the insulation does not extend continuously around the corner as is desired. I therefore provide a filler strip which may be placed in the corner unit so as to carry the insulation all the way round the corner. Special provision is also made for connecting theuunits of one wall to the units of the'other wa The character of cork board is such that plaster, stucco, or the like readily adheres to it. The units are therefor particularly desirable in the construction of stucco houses. While the cementitious coating will adhere to thecork, I preferably place metallic lath or the like over the several units and plaster onto it. The plaster is therefore held in place by the cork and by the lath. The outermost flanges of the channels making up the units are perforated so that nails may be driven through them into the cork. This materially simplifies the securing of the lath to the assembled structure. Similar perfora tions are provided on the inner flanges so that metal lath may be fastened on the inside by wires to receive the inside plaster.

The units are preferably made of a height corresponding to one story of the structure. They are connected by a bearing strip preferably in the form of an angle which carries the floor beams at the junction of units between stories. The bearing strip is preferably so placed that it bears against the inner flanges of the upper and lower units and provision is made for securing both sets of units to this strip.

If desired assembled panels may be dipped in asphalt or other protective medium. This will be eflective for sealing any air openings and for preventing rusting of the frames.

Flgure 11 is a horizontal section taken on the line XI-XI of Figure 2; and

Figure 12 is a view correspond ng to Figure 8, but showing the units after the plaster and stucco have been applied.

Referring first to Figures 1 to 3 inclusive, there is shown a structure built on a foundation F and consisting-of full sized units 2 and 3 and smaller unitsA and 5. The un ts 2 and 3 are each the height of a full story and are used to form all of the solid wall portions of the building. The units 4 and 5 are of less height and are employed Where it is desired to provide a window or door opening.

Each unit consists of metal channels 6, having webs 7 and flanges 8 and. 9, the several channels being welded together at the cor ners as indicated at W in Figure 1. A bean ing strip 10 in the form of a structural angle is secured to the foundation F by bolts 11. The units are fastened to this angle bv bolts 12 extending through the flanges 8 and 9.

The construction of the individual panels is best shown in Figures 4 to 6 inclusive. Each of the frames is, as above stated, made of channel shaped members which are preferably stamped out of a sheet metal. Panels 12 of cork are placed within the units and lie against the flanges 8. They are held in place by angle strips 13 which are secured to the webs 7 as by welding. or the channels may be drawn or rolled with this strip in place. As best shown in Figure 6, the panels .12 are of less depth than the channels 6, so that there is provided an open space S for the reception of pipes, wires, conduits, and the like. Each unit-is provided'in its top and bottom portions with openings-14' for the reception of .bolts 11. The webs of the wide members are punched, as indicated at 15, so that adjacent units may be tied together. The manner of joining the units is best shown in Figures 7 and 8. Links 16 are inserted through the bolts 11?) extending punched slots 15, and wedges 17 are driven in 'tohold the panels together.

Again referring to Figure 1, the first story of the house is shown as made up principally of units 2. The units 3 are similar in all respects to the units 2, but are placed on top of them so as to form the second story. They are fastened together through a bearing strip 18in the form of a structural angle, there being bolts 11a extending through the openings 14 in the tops'of the units 2 and 5, and

through the correspondmg openings in the bottoms of the units '3 and 4. The bolts 11a and 111) are connected at their outer ends by a punched bearing strip 19. The angle 10 supports the floor beams B for the first floor and the angle 18 supports the floor beams B for the second floor. A structural angle 20 connects the panels 3 and 5 at the tops thereof and supports the beams B, for the top floor. The rafters R are carried on a wood plate P which. lies over the tops of the units 3 and 5.

The units which surround the window openings are provided with clips 21 to permit of attaching metal window sash. If double hung windows are used these clips are omitted.

Figures 9 and 10 show the construction employed at the corners; The flanges 9 of the corner units in one wall abut the webs 7 of the corner units in the adjacent wall. The cork panels 12 of the two units are thus remote from one another and the space is filled by a cork strip 22. Such strip is put in place either--before or after the units have been erected. In order to tie the units together at the corners, clips 23 are employed. These clips are punched with openings correspond- The clip 23 extends behind the flange 9, so

that when the wedges are driven home the units are secured together. I

Figure 9 shows a verticall extending anle clip 24 which is employed at the junction etween stories, it being fastened to the flanges of the corner units by bolts 25.

Figure 12 is a section through a completed wall. The outer facing consists of two coats 26 and 27 of cementitlous material such as stucco.- These coats extend over the cork panels 12 as well as over the metal flanges 8. A layer of expanded bedded in the first coat-26. The metal lath is secured to the structure by nails 29, which are driven through. small openings 30 punched in the flanges 8, the heads of the nails being bent over to hold the lath. The metal lath can also be wired on. The clips 13 provide adequate backing for' the cork so that there is no tendency to rupture the same metal lath '28 is emwill be understood,

during nailing. In fact the cork may be under some slight degree of compression at this point. The coating tends to adhere strongly to the cork so that a unitary structure without cracks is assured.

The interior is finished in a similar manner. Expanded metal lath 31 is held in place by small clips or wires 32 extending through openings 30 in the flanges 9, and the plaster coats 33 and 34 are applied thereto.

If brick or stone facing instead of stucco is used, the metal lath is omitted and the brick or stone veneer is set against the outer cork wall with cement mortar and held in place by wall ties fastened to thechannels and extending in the joints of the brick or stone facing.

By the use of my invention a building may be rapidly framed from pre-formed panels. Thesepanels being of large size, they are relatively few .in number so that a verylarge percentage of the total wall surface is cork. Sufficient metal is provided to sustain the structure, but the units are of such character that the metal is very economically employed. When two units are placed side by side an secured together, the adjacent channels act together and may be considered as a column of H or I section. There is no load on the cork, and the cork is thoroughly protected by reason of the wire mesh and stucco coating extending thereover. The structure is highly desirable in that the cork gives high thermal and sound insulation. The air space S is also of value in this respect. Since cork is slow burning, the structure is also desirable in that the fire risk is very low.

I have illustrated and described a present referred embodiment of my invention. It however, that it is not limited to the forms shown, but may be otherwise embodied within the scope of the following claims.
