- the lower portion of the connecting member is deformable and permits side walls to be displaced allowing insertion of the arrowhead 88 a into the recess. But the side walls are resilient. Thus, once arrowhead 88 a has passed a pair of oppositely positioned sawteeth on the sidewalls 82 a and 84 a , axial removal of the arrowhead 88 a is prevented as the side portions of the arrowhead engage the rear sides of the saw-teeth.

Abstract
Description
- This invention relates to tie assemblies and wall form units and systems used to construct structural components such as walls. More particularly, the present invention relates to such tie assemblies, wall form units and form systems for walls formed of a pourable, curable construction material where the form system remains in situ.
- Construction components, such as walls and columns, are often made form castable materials such as concrete. As is well known, to make a specifically shaped component from such materials, a form is built or erected which functions as a mould for the castable material. In the past, forms were typically made form inexpensive materials such as wood. To make the component, the form is erected to create a cavity capable of holding the castable material (eg. concrete) in a liquid form. The concrete is then poured or otherwise fed into the cavity created by the form and then allowed to set. Once the material has hardened into a structural component, the form is removed. After use as a form, quite often, much of the form material can not be reused and must be discarded. Furthermore, the removal of the form requires a significant amount of labour.
- Another way a form can be built is to make a form from several form units, each form unit having a pair of spaced panels. The form units are placed adjacent each other, both horizontally and vertically, to build a complete form. So long as the individual form units are not too small, enhanced efficiency in the construction of a form may be achieved in such a system. This is particularly the case if the form units are designed to remain permanently in the situ, once placed, and do not have to be removed once the concrete has been poured and set. One such system has side panels for each form unit made of an insulative material. These side panels perform the dual purpose of functioning as the side walls for the cavity and then after the concrete has set, as an insulative payer on each side of the concrete.
- It will be appreciated that it is often necessary to construct a wall many metres in length and several meters in height. This will require many form units that must be held together. Particularly in forms which are high, the vertical interconnections between adjacent form units are important as they resist vertical lift forces that tend to lift and separate adjacent form units.
- However, providing interconnections between form units which are effective, but which can quickly be engaged, is problematic. Another difficulty in such systems is the lack of space efficiency in the transportation of pre-built form units to a construction site.
- A form unit that can be assembled at a work site is taught in NL-A-8G00566. This form unit includes panels provided with a tie assembly consisting of embedded connecting members that can receive tie members in a sliding fit. However, the connecting members described therein are expensive to manufacture since they are formed with a solid connecting channel.
- Accordingly, it is desirable to have a form system that employs form units having both efficient and effective form unit interconnections, and the form unit must be capable of being efficiently transported to the construction site.
- According to a preferred embodiment of the present invention, there is provided a tie assembly for a wall form unit. The tie assembly connects a first panel and a second panel which define a space to contain a portable, curable construction material, such as concrete, for forming a wall section. The tie assembly, first and second panels, and the cured construction material combine to form the final wall structure. A spacer member maintains the first and second panels in a predetermined relation. The spacer member has spaced apart, opposing edges, and each edge is provided with connecting means. A first and a second connecting member are each provided with a support for respective attachment to the first and second panels, and a coupling projecting from the support. The coupling defines a channel for sliding engagement with the connecting means. An abutment means permits the coupling and the connecting means to cooperate to detachably retain the connecting means.
- In a further a embodiment of the present invention, there is provided a wall form unit for containing a pourable, curable construction material for forming a wall section integrating the wall form unit and the construction material. The wall form unit comprises a first panel and a second panel in predetermined relation for defining the wall section. A tie assembly includes a spacer member for maintaining the first and second panel in the predetermined relation, opposing first and second connecting members attached to the spacer member, and abutment means for retaining the spacer member in engagement with the connecting member. The spacer member has spaced apart, opposing edges, each the edge provided with connecting means. The first and second connecting members are each provided with a support for attachment, in opposed relation, to the respective first and second panels, and a coupling projecting from the support. The coupling defines a channel for sliding engagement with the connecting means. The abutment means permits the coupling and the connecting means to cooperate to detachably retain the connecting means.
- In a third embodiment of the present invention, there is provided a wall form system for forming a wall section having a core of pourable, curable construction material sheathed by a plurality of panels. The wall form section is constructed from at least two wall form units, each wall form unit having means for interlocking the wall form units to define the wall section. Each wall unit comprise a first panel and a second panel in predetermined relation for receiving the construction material, and at least one tie assembly. The tie assembly comprises a spacer member for maintaining the first panel and the second panel in the predetermined relation, opposing first and second connecting members attached to the spacer member, and abutment means for retaining the spacer member in engagement with the connecting members. The spacer member has spaced apart, opposing edges, each the edge provided with connecting means. The first and second connecting members are each provided with a support for attachment, in opposed relation, to the respective first and second panels, and a coupling projecting from the support. The coupling defines a channel for sliding engagement with the connecting means. The abutment means permits the coupling and the connecting means to cooperate to detachably retain the connecting means.

FIG. 1 , asingle form unit 20 a is illustrated. In the construction of a structural component, for example a wall, severalsuch form units 20 a are utilized.Wall form units 20 a are placed adjacent to, and in lateral alignment with, other form units to make a complete form structure, as illustrated inFIG. 10 . - A
single form unit 20 a has a pair of spaced, generally 10 planar and transversely alignedpanel members panel members - In
FIG. 1 ,form unit 20 a is shown with asingle tie member 26 a in detail. However, to provide greater stability for a form unit, a pair oftie members - As shown in
FIGS. 2 and 3 , eachtie member 26 a comprises three components: a transversely orientedspacer member 30 a and a pair of vertically orientedunit connecting members FIGS. 2 and 3 , theform unit 20 a, including thetie member 26 a, is shown in its disassembled state. However,spacer member 30 a may be easily attached to verticalunit connecting members spacer member 30 a has a recess extending substantially the full vertical length of the spacer member, as is clearly illustrated by a top view inFIG. 4 .Spacer member 30 a, andelements nylon 6/6, PVC or A.B.S. -
Spacer member 30 a also has anindentation 62 a on the uppertransverse arm 63 a of thespacer member 30 a and anindentation 64 a on the lowertransverse arm 65 a of thespacer member 30 a, although other embodiments of this invention may have a plurality of such indentations. Eachindentation indentations indentations - Each of the vertical form
unit connecting members fin 58 a and 60 a extending substantially the full vertical length of the inside end of the connecting member.Recesses 38 a and 40 a are so arranged to cooperate with thefins 58 a and 60 a such that each of the said fins can be received into one of said recesses though one of two apertures inpanels panels form unit 20 a to create the apertures required for the interconnection between thespacer member 30 a and the verticalunit connecting members - The attachment between
recesses 38 a and 40 a andfins 58 a and 60 a is illustrated inFIG. 4 . In this figure, a positive attachment is created when thefin 60 a slides into therecess 40 a in a vertical direction. Therecess 40 a narrows at itsouter margin 41 a in order to grasp the correspondingly narrowedportion 61 a of thefin 60 a and provide a snug fit betweenspacer member 30 a, and connectingelements spacer element 30 a, thus preventing further sliding of the connectingelements FIG. 5 . - This connection, between the
fins 58 a and 60 a and therecesses 38 a and 40 a, is not permanent, and the form units can be reshaped if it is discovered that a mistake was made. - Once the
spacer member 26 a is attached to the vertical unit connecting members, such as 36 a, the vertical unit connecting members are oriented vertically and have a surface which lies against the outward facing surface of a panel. - A may be seen in
FIG. 1 , connectingelements 34 d and 36 a have a laterally (in direction of axis Y) extending channel or groove 76 a in their upper lateral surfaces 75 a and lowerlateral surfaces 77 a. A linkingelement 71 a has a laterally extending tongue orprotrusion 72 a which extends upwards from an upper, lateral surface 74 a and downwards from a lower,lateral surface 79 a. - A pair of form units may be positioned one on top of the other wherein the channel of a lower form unit will be received in corresponding and respective protrusion of a linking element, which is then received in a corresponding and respective channel of an upper form unit (not shown). The result is that displacement of a first upper form unit relative to a second lower form unit is resisted.
- The mechanism for providing a positive connection between adjacent vertically positioned form units is illustrated in further detail in
FIGS. 6, 7 , 8, and 9. - In
FIG. 6 , the lower portion of a typicalunit connecting member 34 a and the upper portion of atypical liking element 71 a are shown disconnected from each other. The unit connecting member and the linking element both lie against the outer surfaces of their respective panels. Formed in the lower portion ofmember 34 a is arecess 76 a defined by an opening and vertically orientedside walls 82 a, 84 a and a base 80 a. Theside walls 82 a, 84 a are each saw-toothed. -
Connection member 54 a has at its upper end anarrow formation 86 a with anarrowhead 88 a. The saw-tooth pattern of thewalls 82 a, 84 a is such that the sloped sides ofarrowhead 88 a are guided and carried past the individual teeth during axial insertion of thearrow formation 86 a into therecess 76 a in the direction of axis z ofFIG. 1 . - The lower portion of the connecting member is deformable and permits side walls to be displaced allowing insertion of the
arrowhead 88 a into the recess. But the side walls are resilient. Thus, oncearrowhead 88 a has passed a pair of oppositely positioned sawteeth on the sidewalls 82 a and 84 a, axial removal of thearrowhead 88 a is prevented as the side portions of the arrowhead engage the rear sides of the saw-teeth. - However, even when two
form units 20 a and 20 d have been interconnected through use of linkingelement 71 a andconnection members FIG. 9 , therecess 76 a is still accessible. Thus, if it is desired to disconnect the connection betweenarrowhead 86 a and theside walls 82 a and 84 a of the recess, a transverse application of force in a manner generally depicted inFIG. 9 (generally in the direction along of axis Y inFIG. 1 ), permitsarrowhead 88 a to become dislodged from the side walls. - The dimensions of the
arrowhead formation 86 a and the materials from which it is made, are such that it would be quite stiff and a have a relatively high degree of resistance to bending. Typically it would require a lever device to be employed to bend the arrowhead out of the recess to release the connection. Such a lever device might be a crow bar or a hammer claw. - When building a form from many form units, it is necessary that there also be a lateral interconnection between form units. This can be accomplished by erecting a form with form units such as those of
FIG. 1 placed in a pattern as shown inFIG. 10 . In this embodiment, each form unit has a pair of vertical form unit connecting members. Each form unit is off-set in its lateral position relative to form unit above and below. Taking onesuch form unit 20 e, one of the pair of connectingmembers 26 e is connected to a connectingmember 28 g of aform unit 20 g, and also to a connectingmember 28 k of aform unit 20 k. The other of the pair of connecting members 28 c is connected to connectingmember 26 f of aform unit 20 f also to a connectingmember 26 h of aform unit 20 h. - In use, individual panels and the components of the tie members may be shipped to a construction site. The components of the tie members can be conveniently packaged as kits. Unassembled, the components of the form system can be efficiently carried by conventional transport devices. Once at the site, the wall forming units can be easily assembled by using a pair of panels and the components of at least one tie member, but preferably using as least two tie members. For each tie member, a spacer portion is positioned in between the two panels, with its connecting members each passing through an aperture in a panel. A pair of vertical connecting members will be secured in a vertical orientation, against the outer surface of each panel and then will be attached to the spacer member by the attachment of the connecting members to the spacer members as described above.
- As many form units are built as required to construct a complete form for the desired structure. If the form is not continuous, the ends of the form may blocked in a conventional means, so as to provide a complete cavity which will hold the liquid concrete.
- In a construction project, the lower most form units may be secured to a base in lateral alignment (for example, a previously poured footing) providing an interconnection between a concrete footing made with a sill secured to the concrete (eg. by concrete nails) and then providing interconnections between the sill and the vertical unit connecting members.
- Thereafter, form units may be placed on top of the base form units and interconnected such as in the manner described above. Preferably, each form unit will comprise at least a pair of laterally spaced tie members. This will provide for greater vertical stability of the form and assist in the construction process.
- Once the concrete has set, the panels will remain in situ. The vertical unit connecting members will provide a base to which other finishing components may be attached (for example, dry wall for interior walls, siding on exterior walls).
- A further embodiment of the present invention is illustrated in
FIG. 12 .FIG. 12 shows a cutaway view of awall form unit 100, including atie assembly 104, previously referred to as a tie member, connecting two opposingpanels 108. -
Tie assembly 104 is an interconnected assembly of aspacer member 112 and two connectingmembers 116.Spacer member 112 consists ofedges 120 spaced apart by a plurality ofarm members 124. As illustrated,arm members 124 can be provider withindentations 126 for supporting reinforcing members, such as conventional rebar, as described above.Edges 120 have a generally T-shaped profile for engaging complementary T-shapedchannel 130 provided on connectingmembers 116. Anend 132 of eachedge 120 is also provided with anabutment 134 which limits the sliding engagement betweenedges 120 andchannel 130. - As described above, connecting
members 116 consist of a support portion 136 supporting a projectingcoupling 138, previously designated a connection means. Coupling 138 is formed by two opposingrows teeth 144 definingchannel 130. The substantially L-shapedteeth 144give channel 130 its T-shaped profile complementary to edge 120. - In this further embodiment of the present invention, the support portion 136 of connecting
member 116 is embedded in itsrespective panel 108. Typically, connectingmember 116 is an extruded, or otherwise molded, plastic component andpanel 108 is a blown polystyrene panel. Connectingmembers 116 can be prefabricated and then provided to insulating panel manufacturers. The polystyrene panels can then be manufactured in known conventional manners to incorporate the connectingmembers 116 in a predetermined arrangement suitable for their interconnection to formwall form units 100. In a preferred embodiment, the connectingmembers 116 are embedded in the panel such thatcoupling 138 is disposed within agroove 146, but still accessible for interconnection with theedges 120 ofspacer member 112. - A further feature of this embodiment, as shown in
FIGS. 13 a and 13 b, is the provision of an integral means for interlocking thepanels 108 to form a wall form system. A ridged, interlockingstructure 150 is provided at one edge of thepanel 108, and a complementarygrooved interlocking structure 152 is provided on the opposite edge. The ridgedinterlocking structure 150 andgrooved interlocking structure 152 permit thewall form units 100 to be stacked and retain theunits 100 in place. As will be apparent to those skilled in the art, a wall form system constructed of stackedwall form units 100 will not require separate interconnecting means as described in the previous embodiment. - The outer facing surfaces of the panels may be recessed to provide a recess into, which the vertical unit connecting members way be received such that when the form unit is assembled, the vertical connecting members have outward facing surfaces which sit flush with the remaining parts of the outer surfaces of the panels.
- The above-described embodiments of the invention are intended to be examples of the present invention and alterations and modifications may be affected thereto, by those of skill in the art, without departing from the scope of the invention which is defined solely by the claims appended hereto.
