Description
WO 95/35421 219 3 6 3 0 pCT/CA95/00353 TITLE OF THE INVENTION
WEB MEMBER FOR CONCRETE FORM WALLS
This application relates to a building component of the type which is used to build up permanent concrete form walls in building construction.
BACKGROUND OF THE INVENTION
In conventional construction in North America concrete walls are normally produced by constructing form walls, pouring concrete into the space between the form walls and, upon the setting of the concrete, removing the form walls. Finishing materials are then added to the concrete walls as required.
Typically in residential construction, concrete basement and other concrete walls will be constructed in the manner discussed above and wood framing will be constructed as required on top of or beside the walls. Insulation will be inserted between the framing members and the wall finished inside and out as desired.
Clearly both parts of this construction are inefficient.
It is time-consuming and wasteful of materials to have to remove the form walls after the concrete walls are poured. Furthermore, it is now common to insulate all walls, including basement walls, particularly in colder climates, and framing and insulation must be installed separately inside the walls.
The piecemeal construction which is inherent in the wood frame part of the structure is labour-intensive and expensive.
As a result, there have been ongoing efforts for many, many years to provide more modular types of wall construction from which efficiencies can be gained.
One such construction type is that with which the current invention is concerned.
For some 15 years a system has been in use particularly in Europe which combines a number of the operations normally associated with residential and other building construction to provide savings in materials, energy, etc. The system basically comprises the use of a foam insulating material to construct permanent form walls. The form walls are constructed and the concrete poured and the form walls then left in place. The concrete walls so formed need not be confined to basement walls but may comprise all of a building's walls. No further insulation is necessary, and finishing materials may be applied to the interior and exterior of the wall as required.
Variations on this system have been proposed to achieve various improvements. All of the systems thus far proposed, while in many cases very useful, suffer from some or other disadvantages.
Against this background the present invention provides a building component for use in such a system which when integrated into a wall construction offers advantages over prior art such systems.

?193630 DETAILED DESCRIPTION OF THE PREFERRED EMEODIMENTS
The building component 10 comprises first and second foam panels 12 and 14 secured together by at least two bridging members 42.
Panel 12 comprises inner and outer surfaces 18 and 20. , ._.~.
respectively, top and bottom 22 and 24 respectively, and first and ,.
second ends 26 and 28. Panel 14 comprises inner and outer ' ,..
surfaces 30 and 32, top and bottom 34 and 36, and first and second ends 38 and 40.
The panels 12 and 14 are preferably fire retardant : .
expanded polystyrene, polyethylene or polypropylene. Subject to .:
indentations and protrusions of minor height to be discussed below, the panels are of uniform rectangular cross-section. In a typical case each panel may be 48 inches long, 16 3/4 inches high and 2 5/8 inches thick.
Bridging members 42 comprise a pair of elongated end plates 44 and 46 joined by narrow strip member 48.
As illustrated, for example, in Figure 1, the end plates 44 and 46 have their outer surfaces 50 and 52 respectively substantially flush with the outer surfaces 20 and 32 of panels 12 and 14 respectively. End plates 44 and 46 are oriented vertically relative to panels 12 and 14. Throughout this specification ~ references to vertical and horizontal are intended to indicate the orientation of component 10 in position of use in a vertical wall.
In the preferred configuration of bridging members 42, as illustrated in Figures 4 to 6, the narrow strip member 48 has a stepped configuration such that a first part 54 is horizontally offset at 56 from a second part 58.
~!IIIF_NDE~J S~IE~' .r;..~c.
Narrow bracing members 60, 62, 64 and 66 extend between a mid-area 68 of narrow strip member 48 and positions 70, 72, 74 and 76 close to but spaced from the extremities 78, 80, 82 and 84 of end plates 44 and 46. In the preferred embodiment end plates 44 and 46 include on the inner surfaces 86 and 88 thereof elongated reinforcing ribs 90 and 92 which are integral with the respective ends of bracing members 60, 62, 64 and 66.
Bridging member 42 includes second bracing members 94, 96, 98 and 100 between narrow strip member 48 and first bracing IO members 60, 62, 64 and 66 respectively. In the preferred configuration second bracing members 94, 96, 98 and 100 are ;
substantially vertically oriented and have their inner edges 102, ; ;
104, 106 and 108 respectively substantially flush with inner '..
surfaces 18 and 30 respectively of panels 12 and 14.

Mid-area 68 is preferably enlarged and profiled to provide a series of seats for rebar positioning. Thus, utilizing the seats 122 provides an open pattern of rebar. Use of seats 124 provides a more closed pattern. Seats 126 provide one or two centred rebar rods.
In order to position and stabilize vertical rebar in constructing the wall, horizontal rebar may be placed in alternate seats, as selected, with the vertical rebar then placed between horizontal rebar. For example, horizontal rebar may be placed in seats 124 with vertical rebar in the space between.

Each bridging member 42 comprises a single integral unit '"~
molded of plastic. The preferred plastic is high-density flame retardant polyethylene, although flame retardant polypropylene, polystyrene and other-suitable polymers may be used.
The bridging members 42 are molded into the panels 12 and 14 in the course of producing the panels. As best seen in Figure 1, the end plates 44 and 46 are preferably of substantially equal height with the panels 12 and 14 and are substantially flush with the top and bottom of the panels, subject to the vertical joining means on the panels, to be discussed below.

This will normally be at grade. In current construction considerable cost and labour is expended in providing footings for brick cladding where a brick structure is being constructed. The embodiment of Figures 8 to 10 permits an integral brick shelf to be constructed.
Thus, the building component 210 comprises first and second foam panels 212 and 214 secured together by at least two bridging members 242.
'~ivi'~~ ~1''°x;11 :..m ~-' .~~LL~ sJn .?...i.. .
iPE!~iE~
Panel 212 comprises inner and outer surfaces 218 and 220 respectively, top and bottom 222 and 224 respectively, and first and second ends 226 and 228. Panel 214 comprises inner and outer surfaces 230 and 232, top and bottom 234 and 236, and first and second ends 238 and 240.
As can be seen in Figures 8 to 10, the top 222 of panel 212 is substantially thicker than the bottom 224. The outer surface 220 of panel 212 is profiled to extend outwardly and upwardly from bottom 224 to the top 222. In the preferred configuration bottom part 244 of panel 212 is the same thickness as panel 214 and of other panels in a wall. At part 244 the outer surface 220 is preferably vertical. A top part 246 of panel 212 is substantially thicker than bottom part 244. Outer surface 220 at part 246 is also preferably vertical. At an intermediate part 248 ~"
....
of panel 212 the outer surface 220 is profiled to join lower part .
244 to thicker upper part 246. '.;, As illustrated in Figures 8 and 9, parts of thicker upper '..' part 246 of panel 212 are cut away (by means of mold cavities rather than by actual cutting) in areas which do not contain bridging members 242. The cut-away areas 250 are thus open to the space 252 between the panels.
The inner surface 218 of panel 212 in the area of cut-aways 250 is profiled as at 254 to follow the profile of outer surface 220, although not necessarily at uniform distance from that outer surface.
It will thus be seen that when a wall is constructed in the usual way which includes a course of modified components 210 (see Figure 17), and when concrete is poured to form the core of >,,-"~_,. ._ ;~c--~
,<1,f ~ ', _: . a,i :~ ~ .!._~~. ;
~,a.~ ~-the wall, the concrete will fill the cut-aways or cavities 250 to form the brick shelf integral with the wall.
The solid foam partitions 256 between cut-aways 250 preferably include a slot 258 to support rebar or other reinforcing means for the shelf.
A further problem which arises in the construction of form walls concerns the difficulty in establishing correct angles where a directional change in a wall of less than 90° is required.
If, for example, the angle in a foundation wall is incorrect by a small amount, the entire building above that part of the foundation is affected. Accordingly, the embodiment of Figures 11 to 16 has :..
been devised to enable a range of directional changes or corners to ' '.
be accurately constructed in a form wall, providing continuity in ~.
..
the form wall.
Thus, the component 310 comprises panels 312 and 314 ,.
secured together by a series of bridging members 342. Panel 312 ', comprises inner and outer surfaces 318 and 320 respectively, and ..' first and second ends 326 and 328. Panel 314 comprises inner and outer surfaces 330 and 332, top and bottom 334 and 336, and first and second ends 338 and 340.
At the end of component 310 integral end parts 344 and 346 are shown. These end parts are seen to be integral with panels 312 and 314 respectively. Each of end parts 344 and 346 is ~ preferably semi-circular in configuration.
As illustrated in Figure 13, end part 344 extends from the upper half of ends 326 and 328 of panels 312 and 314; and end part 346 extends from the lower half of ends 328 and 340 of the panels. End part 344 preferably includes in a lower surface 348 thereof a central semi-circular groove 350.
AMENDED SHEET
IPEA/EP
The upper surface 352 of end part 346 includes a complementary central raised tongue 354 of semi-circular plan.
When a change of direction of, say, 30° is required in a wall, the component 310 can be bisected at an appropriate point and turned end to end to form part components 310a and 310b (Figure 11). The tongue 354 can then be mated with the groove 350 and the units rotated to the required angle. At that point a part of the end parts 344 and 346 will cross the space 356 between the panels.
That part of the end parts 344 and 346 can then simply be cut out to allow the concrete core to be installed.
The ends 326 and 328 of panel 310, and 338 and 340 of ;,_, panel 314 are angled as shown at 356, 358, 360 and 362 to ;
..
accommodate the semi-circular end parts 344 and 346 over a range of , , , rotation. "' ...
While a preferred configuration of this embodiment has .~
been described, a number of variations are possible. For example, ',', ...
. a rather than being of semi-circular configuration, the end parts may '..' be stepped to accommodate specific predetermined angles as in a semi-hexagonal configuration.
As well, only one of end parts 344 and 346 may be present on a given component with a second complementary and mating end part on a second component. There are, however, advantages in including the two end parts on a single component. These include ~ the very significant fact that only a single mold is required for that case. As well, where the double-ended panels are utilized, builders will always be sure of having available an equal number of half joints.
The highly preferred overlapping configuration of blocks in a wall can be achieved with the double-ended unit by bisecting A1~ENDED SHEET
f PEA/EP
succeeding double-ended blocks at different locations along their length into non-equal parts.
In the typical basic component discussed earlier (e. g. Figure 1), of 48-inch width, the bridging members 42 will preferably be spaced on 8-inch centres with the two bridging members closest to the ends of the component located 4 inches from the ends. Thus, when the panels are overlapped to form the wall, the bridging members of the various courses can be aligned to form continuous strips of end plates 44 and 46 over the entire height of the wall. This is a very significant advantage of the present system, since interior or exterior wall cladding can be fixed to ;:,.
the exterior of the end plates 44 and 46, preferably using screws.
Drainage is provided and parging and damp-proofing of the , :, exterior as is the case with a conventional concrete basement wall.
...
Using the typical dimensions noted above with a panel ., separation of 6 1/4 inches (6 1/4 inches of concrete) the ',:, ...
insulating value of the wall is R26. This is a very high rating '..' for wall construction and thus no additional insulation is required. In addition to the energy-saving value of the insulation, the walls- have high resistance to sound transmission with a typical sound reduction of 53DBA.
The typical component noted above will weigh only about 2.8 kgs. and so provides a substantial advantage to tradesmen ~ building a wall.
