The invention relates to a form consisting of many unitary parts, which can be relatively quickly and easily assembled and utilized in the pouring of concrete walls.
Description
- :11403~
This invention relates to forms suitable for use in the pouring of concrete walls. Such forms, ganged together, are well known in the building industry and are usually composed of many integers which must be bolted together to serve as supports for the plywood panels between which the liquid concrete is poured.
The measure of efficiency and the basis of labour costs when considering the use of such forms can be expressed in square feet of form contact area per man-hour and this expression is applicable both to what is known as job-built formwork as well as to the unitary method of formwork, the latter being infinitely superior to the former because of the reduction in labour involved and because such forms can be re-used for more times than job~built formwork. Hence, unitary forms present a significant saving in both labour and material costs.
One type of unitary form, and the assembly thereof, includes the initial placement on a jig of complementary pairs of first profiled structural me~bers in spaced parallel relationship to one another and each having a pair of complementary T-shaped slots. One cf the slots is provided with a lumber insert and this end of each structural member is placed face down on the jig.
T-bolts, cooperating with clamp members, are then slidden into the T-shaped slots in the upper ends of the s-tructural members.
Strongback members must then be assembled by placing complementary pairs of parallel second structural members on the first members so as to extend normal thereto, each said second member being provided with a pair of complementary spaced T-shaped slots adapted to receive additional T-bolts therein. Tie-plates each provided with spaced U-shaped slots and a central hole, .,~
36~
are then placed on the second structural members and the said additional T-bolts inserted in said slots and tightened. Hence, the tie-plates secure each pair of second structural members in spaced relation to form a strongback. The clamp members are then positioned so that they will clamp the strongbacks to the first structural members, and the first--mentioned T-bolts are then tightened. The assembled unit is then raised and turned over so that the lumber inserts will face upwardly to receive plywood panels which are then nailed to the inserts. The holes in the tie-plates are then located and corresponding holes are then drilled in said panels. The unit is then framed in lumber and is then lifted into its service position ready to receive additional accessories such as walkways etc.
Assembling such a form is extremely time-consuming and the amount of integers required to construct the form naturally requires an extremely large stock of items to be maintained.
Hence, it is the object of the present invention to provide a form, and a method of assembly, which is much simpler than hitherto known unitary structures whereby the number of required integers ~0 and the amount of assembly time is drastically reduced.
According to one broad aspect therefore, the present invention relates to a form utilized in the pouring of concrete walls, said form including (a) a plurality of spaced parallcl profiled primary strongback members provided with stub flanges;
(b) a plurality of spaced paralle~l profiled structural members having stub flanges and lumber inserts; (c) a plurality of clamp members detachably engageable with said stub flanges of adjacent strongback and structural memhers to maintain said strongback and 11~C)3~1 structural members normal to one another; (d) a plurality of plywood panels detachably secured to said lumber inserts; and (e) a plurality of tie plates and cooperating tie bolts detachably secured to the stub flanges of the strongback members, said tie bolts extending through said plywood panels; said form being capable of connection to, but spaced from a complementary form whereby concrete can be poured between the pair of forms to produce a poured concrete wall.
According to another broad aspect, the invention relates to assembling a form utilized in the pouring of concrete walls, including the steps of (a) the placement of a plurality of profiled primary strongback members, provided with stub flanges, in spaced parallel relationship; (b) placing a plurality of spaced parallel profiled structural members having stub flanges and lumber inserts on said strongback members to extend normal thereto with said inserts facing upwardly; (c) detachably securing a plurality of - clamp members to adjacent stub flanges of said strongback and structural members so as to maintain them in said normal relationship; (d) detachably securing a plurality of plywood panels to said lumber inserts; (e) drilling a plurality of locating holes in said panels; (f) raising said form to a vertical position;
(g) detachably securing a plurality of tie plates to said strong-back members by means of said clamp members; and (h) passing a plurality of tie bolts through said tie plates, through said strongbacks and between selected adjacent pairs of said structural members so that they project through said holes; said form being capable of connection to, but spaced from, a complementary form whereby concrete can be poured between the pair of forms to ~14~)36~
produce a poured concrete wall.
The inven-tion is illustrated, by way of example, in the accompanying drawings in which:
Figure 1 is a diagrammatic perspective view of the form:
Figure 2 is a side view of Figure l;
Figure 3 is a detail view; and Figure 4 is a side view of Figure 3.
Referring to the drawings, a form (which can either be assembled on site or at the plant) utilized in the pouring of concrete walls includes a plurality of spaced parallel profiled strongback members indicated generally at 1 which are preferably of the type described and claimed in copending Canadian Application Serial No. 368,381 filed January 13th 1981 by the present Applicant and which have stub flanges 2 of substantially conical cross-section. It will be appreciated that, if desired, connector plates 3, located either side of a pair of strongbacks, will connect the latter in end-to-end relation. The ends of the strongback members can, if desired, be fitted with shoes 8 which, if required, can be fitted with a lifting eye such as those indicated at 9, 9'.
The shoes effectively close the open ends of the members 1 to inhibit the entry of foreign matter therein and damage to the ends of the strongbacks.
The strongbacks 1 are then preferably placed on a jig in spaced parallel formation and, thereafter, a plurality of spaced parallel structural members, indicated generally at 4, having stub flanges 5 of substantially conical cross-section and lumber inserts 6 (see Figure 2) are then placed on said strongbacks so as to extend normal thereto and whereby ~aid inserts face ~ -4-~1~036~
upwardly. preferably, the structural members are of the types described and claimed in copending Canadian Application Serial No.
368,473 filed January 14th 1981 by the present Applicant. Profiled clamp members, indicated generally at 7 and having grooves com-plementing the stub flanges are adapted detachably to clamp the strongback members 1 to the strucural members 4, said clamps 7 preferably being of the type described and claimed in copending Canadian Application Serial No. 368,630 filed January 15th 1981 by the present Applicant.
Plywood sheets 10 are then placed on the structural members 4 and nailed to the inserts 6. Holes (not shown) are then drilled in said plywood facing which is surrounded by a lumber frame 11.
A crane (not shown) through the intermediary of the lift-ing eyes 9 or 9' then raises the form (constructed thus far) to the vertical.
A plurality of slotted and bore tie-plates, indicated generally at 12, and preferably of the type forming the subject of Canadian Application Serial No. 369,662 filed January 29th 1981 by the present Applicant are then detachably secured to the flanges of the strongback members 1 by means of said clamps 7 engaging said slots. Each tie-plate 12 has a coopera-ting threaded tie-bolt 13 which passes between the cheek members of the s-trongback members 1 and through the holes in the plywood 10 so as to extend therefrom.
While the form is hanging :in the vertical, adjustable plumbing and support frames, indicated generally at 14 are connected to certain of the strongback members 1 adjacent their lower ends and walk-way brackets (indicated generally at 15 and which may also be adjustable) are connected to certain of the strongback members adjacent their upper ends, by means of the aforesaid clamps 7, which clamp the brackets 15 to the stub flanges 2 of said strongback members 1. The walk-way brackets 15 have upright post members lG detachably secured thereto which serve to support a safety fence 17. The brackets also serve to support a walk-way 18.
When a pair of complementary forms have been erected vertically, so that the tie-bolts 13 maintain said pair of forms in spaced relation, concrete is then poured between the space existing between the facing plywood sheets iO to form a poured concrete wall W. After the latter has set, and if it is desired to increase the height of the wall by further pouring, the forms are then raised vertically by a crane, leaving the tie-bolts 13 behind. Additional strongback members 1' are then connected to the lower ends of the members 1 of the form by means of connector plates 3 as is shown in Figure 3.
A combined climbing and plumbing bracket, indicated generally at 20 in Figures 3 and 4, is detachably secured to the outer end of a tie bolt 13 adjacent the top of the poured and set wall section. The bracket 20, has a pair of side flanges 21 and a pair of inwardly converging cheeks 22 located adjacent the lower end of the said bracket with a closed slot (not shown) in said lower end and between the cheeks 22.
A locking pin holder, indicated generally at 23 is detachably secured within a lower strongback member 1' by bolts 24 and cooperating nuts. The upper and lower ends of said holder are constituted by a pair of tubes 25, the outer end of the upper tube 25 being provided with a depending locking pin 26, The lower tube 25 is adapted to receive a threaded jack 27 provided at its outer ~40361 end with a fixed base-plate 28 which is adapted to be placed in face-to-face contact with the face of the poured and set section of the wall. The jack 27 is provided with a cooperating adjustment nut 29 and a nut 30 at its other end to retain it within the lower tube 25.
Accordingly, once the additional strongbacks 1' have been secured to the lower ends of strongbacks 1 and the climbing brackets 20, holders 23 and jacks 27 have been placed in position, the crane will then guide the assembled form whereby the lower end of the first form will be in face-to-face contact with the upper portion of the first poured and set section of the wall.
As the assembled form is lowered into this position, the cheeks 22 of the climbing bracket 20 serve to guide the locking pin 26 into the slot in the lower end of said bracket thereby retaining the assembled form in juxtaposition wi-th the poured and set section of the wall. Thereafter, and to adjust the vertical alignment of the assembled form in relation to the poured and set section of the wall, it is merely necessary to adjust nut 29 on the screw jack 27 either towards or away from said wall thereby adjusting the vertical inclination of strongbacks 1' and, hence, strongbac]cs 1.
This invention relates to forms suitable for use in the pouring of concrete walls. Such forms, ganged together, are well known in the building industry and are usually composed of many integers which must be bolted together to serve as supports for the plywood panels between which the liquid concrete is poured.
The measure of efficiency and the basis of labour costs when considering the use of such forms can be expressed in square feet of form contact area per man-hour and this expression is applicable both to what is known as job-built formwork as well as to the unitary method of formwork, the latter being infinitely superior to the former because of the reduction in labour involved and because such forms can be re-used for more times than job~built formwork. Hence, unitary forms present a significant saving in both labour and material costs.
One type of unitary form, and the assembly thereof, includes the initial placement on a jig of complementary pairs of first profiled structural me~bers in spaced parallel relationship to one another and each having a pair of complementary T-shaped slots. One cf the slots is provided with a lumber insert and this end of each structural member is placed face down on the jig.
T-bolts, cooperating with clamp members, are then slidden into the T-shaped slots in the upper ends of the s-tructural members.
Strongback members must then be assembled by placing complementary pairs of parallel second structural members on the first members so as to extend normal thereto, each said second member being provided with a pair of complementary spaced T-shaped slots adapted to receive additional T-bolts therein. Tie-plates each provided with spaced U-shaped slots and a central hole, .,~
36~
are then placed on the second structural members and the said additional T-bolts inserted in said slots and tightened. Hence, the tie-plates secure each pair of second structural members in spaced relation to form a strongback. The clamp members are then positioned so that they will clamp the strongbacks to the first structural members, and the first--mentioned T-bolts are then tightened. The assembled unit is then raised and turned over so that the lumber inserts will face upwardly to receive plywood panels which are then nailed to the inserts. The holes in the tie-plates are then located and corresponding holes are then drilled in said panels. The unit is then framed in lumber and is then lifted into its service position ready to receive additional accessories such as walkways etc.

The shoes effectively close the open ends of the members 1 to inhibit the entry of foreign matter therein and damage to the ends of the strongbacks.
The strongbacks 1 are then preferably placed on a jig in spaced parallel formation and, thereafter, a plurality of spaced parallel structural members, indicated generally at 4, having stub flanges 5 of substantially conical cross-section and lumber inserts 6 (see Figure 2) are then placed on said strongbacks so as to extend normal thereto and whereby ~aid inserts face ~ -4-~1~036~
upwardly. preferably, the structural members are of the types described and claimed in copending Canadian Application Serial No.
368,473 filed January 14th 1981 by the present Applicant. Profiled clamp members, indicated generally at 7 and having grooves com-plementing the stub flanges are adapted detachably to clamp the strongback members 1 to the strucural members 4, said clamps 7 preferably being of the type described and claimed in copending Canadian Application Serial No. 368,630 filed January 15th 1981 by the present Applicant.
Plywood sheets 10 are then placed on the structural members 4 and nailed to the inserts 6. Holes (not shown) are then drilled in said plywood facing which is surrounded by a lumber frame 11.
A crane (not shown) through the intermediary of the lift-ing eyes 9 or 9' then raises the form (constructed thus far) to the vertical.
A plurality of slotted and bore tie-plates, indicated generally at 12, and preferably of the type forming the subject of Canadian Application Serial No. 369,662 filed January 29th 1981 by the present Applicant are then detachably secured to the flanges of the strongback members 1 by means of said clamps 7 engaging said slots. Each tie-plate 12 has a coopera-ting threaded tie-bolt 13 which passes between the cheek members of the s-trongback members 1 and through the holes in the plywood 10 so as to extend therefrom.
While the form is hanging :in the vertical, adjustable plumbing and support frames, indicated generally at 14 are connected to certain of the strongback members 1 adjacent their lower ends and walk-way brackets (indicated generally at 15 and which may also be adjustable) are connected to certain of the strongback members adjacent their upper ends, by means of the aforesaid clamps 7, which clamp the brackets 15 to the stub flanges 2 of said strongback members 1. The walk-way brackets 15 have upright post members lG detachably secured thereto which serve to support a safety fence 17. The brackets also serve to support a walk-way 18.
