Abstract

A wall form arrangement of the type used in forming composition walls, such as concrete walls, which includes a pair of vertically stacked wall forms. Each wall form has horizontally extending angle iron walers on its outer side. The stacked wall forms are reinforced by a vertically extending channel positioned against the outer side of the forms and having downwardly facing hooks thereon engaging the angle iron walers and drawing the channel against the walers. A hook at the lower end of the channel is adapted to be drawn upwardly to interengage the bottom waler on the lower wall form to secure the two wall forms in rigidly clamped vertically aligned relation.

INVENTOR. EMIL. YURICK k/VV/ yxnyyvu BY W M M m ATTORNEYS stacked forms 10 VERTICAL STIFFENING ARRANGEMENT FOR WALL FORMS This invention relates to a stiffener for forms used for pouring composition walls, such as concrete walls.

In the pouring of concrete walls for building structures wall forms are commonly employed. These wall forms are positioned vertically in spaced-apart relation and the concrete poured therebetween to form the wall. It is not uncommon to fabricate such wall forms to a standard height, such as 8 feet. In pouring a basement wall for a residence for example, an 8- foot high wall form is adequate. However, when the wall to be poured has a height greater than the individual wall form, it becomes necessary to stack two or more wall forms vertically edgewise one upon another. When the wall forms are arranged in this manner some form of vertical stiffener is required to retain the upper and lower wall forms in vertically aligned coplanar relation.

It is an object of the present invention to provide a stiffener of the type described which is adapted for easy application to vertically stacked wall forms and which is designed to rigidly clamp the wall forms vertically together and to reinforce the wall forms against horizontal flexing. In the Drawings:

FIG. 1 is a fragmentary perspective view of a wall form arrangement employing the vertical stiffener of the present invention.

FIG. 2 is a side elevational view of the stiffener.

FIg. 3 is a fragmentary view of the stiffener partly in section and illustrating the manner in which it is engaged with walers on the wall forms.

FIG. 4 is an end view of the stiffener as seen from the upper 4 end thereof.

FIG. 5 is a fragmentary elevational view showing the means for clamping the stiffener on the wall forms.

Referring to FIG. I a generally typical arrangement of wall forms is illustrated. There is shown a lower wall form and an upper wall form 12 which are stacked edgewise upon one another for pouring a concrete wall 14 having a height which corresponds generally to the vertical dimension of the two and 12. Each wall form comprises a framework of wood members including horizontally extending

members

16 and 18 which are interconnected by vertically extending members 20. Members l6, l8 and 20 are secured together to form a rectangular frames which are faced on one side thereof by wood panels 22. Panels 22 provide the inner faces of wall forms 10 and 12. The wall forms are additionally reinforced on their outer faces by horizontally extending metal walers 24.

As shown in FIG. 3, each waler 24 comprises a structural angle .iron having a vertically extending flange 26 and a horizontally extending flange 28. Walers 24 are arranged in pairs so that the horizontal flanges in each pair of walers face one another in parallel spaced relation. The vertical wood frame members 20 are notched along their outer edges as at 30 to accommodate walers 24, the walers being mounted on members 20 by screws 32. Walers 24 are secured to the outer faces of panels 10 and 12 so that the outer faces of their vertical flanges 26 are substantially coplanar with the outer edge faces 34 of upright mcmbcrs 20. The pairs of walers 24 extend horizontally on wall forms l0 and I2 and are accurately located on the wall forms such that, when the wall forms are stacked one upon another as shown in FIG. 1, the sets of walers 24 are spaced apart vertically at regular intervals. In addition, the walers are preferably located at positions spaced from the upper and

lower frame members

16, 18, respectively.

Although there is illustrated in the drawings only one pair of wall forms 10 and 12 which provide one side of the wall 14 to be poured, it will be appreciated that a similar set of wall forms is employed in laterally parallel spaced relation to the pair of wall forms illustrated, the lateral spacing corresponding to the thickness of the wall desired. Various means are employed for interconnecting the two sets of wall forms, such as v or bulging when concrete to prevent the forms from shifting is poured therebetween. However, when wall forms are stacked edgewise one upon another as by tie rods (not illustrated),

shown in FIG. I it also becomes necessary in most instances to apply a vertical stiffener which spans wall forms 10 and 12 so as to maintain the wood facing panels 22 in straight vertically extending coplanar relation.

In the arrangement according to this invention a metal stiffener is employed. The stiffener is designated 36. As shown in FIGS. 1 and 4, stiffener 36 is preferably formed as a straight section of structural steel channel having parallel sidewalls 38 interconnected by a flat wall 40. At regularly spaced intervals along channel 36 pairs of hooks 42 are welded to the outer faces of sidewalls 38. Each hook 42 has a shank 44 and a downwardly facing return bent hooked end 46. The pairs of hooks 42 are spaced lengthwise of channel 36 to correspond with the vertical spacing between the sets of walers 24. The construction is such that when channel 36 is positioned against the outer faces of stacked forms 10 and 12 and shifted vertically downwardly each set of hooks 42 is adapted to engage with the vertical flange portion 26 of the upper waler 24 in each pair (except the bottom pair of walers on lower panel 10). In addition, it will be noted that hooks 42 are shaped and located on channel 36 so that when they interengage with the vertical flanges of upper walers 24, connecting wall 40 of 'channel 36 is positioned against the outer faces of vertical flanges 26 of the walers. In other words, when channel 36 is positioned against the outer face of the stacked wall forms as shown in FIG. 1 and interengaged with walers 24, hooks 42 serve to vertically align the two wall forms 10 and 12 so that panels 22 thereon are in straight coplanar relation.

At the lower end of channel 36 there is arranged an additional hook member 48 which is formed as a box section comprising two side plate hooks 50 interconnected by a vertical wall 52 and a pair of transversely extending

plates

54, 56 adjacent opposite ends. Hook member 48 is adapted to be slideztbly arranged within the lower end of channel 36, and, when arranged therein as shown in FIG. 3, hook member 48 is adapted to be shifted vertically upwardly so that the hooked ends 58 of side plates 50 engage under and behind the vertical flange 26 of the bottom waler 24 in the lowermost set of walers on lower wall form 10. Plate 56 is apertured to receive a screw 60 therethrough. An apertured anchor plate 62 is welded within channel 36 at a location spaced upwardly from the lower end thereof. Screw 60 is adapted to extend through apertured plate 62 and engage with nut 66.

In use, after the two wall forms 10 and 12 are vertically stacked upon one another as shown in FIG. 1, stiffener 36 is positioned against the outer side of the stacked wall forms, preferably at the location of a vertical frame member 20, and shifted vertically downwardly to interengage hooks 42 with the vertical flanges 26 of the upper walers 24. Thereafter hook member 48 is arranged within the lower end of channel 36 and shifted upwardly so that the hooked ends 58 engage under and behind the vertical flange 26 of the lower waler in the lowermost pair of walers 24. Screw 60 is then inserted through

apertured plates

56, 62 and tightened on nut 66 to draw hook member 48 upwardly. When screw 60 is thus tightened the two wall forms 10 and 12 are not only drawn into vertical alignment so that the panels 22 thereof are coplanar but they are also tightly clamped together in a vertical direction so that the two panels from a rigid structure.
