This invention relates to a system of wall forms such as are used for the purpose of pouring concrete, cement and the like, in the fabrication of foundations and building structures.

Where forms are used in the pouring of concrete, it is customary to fabricate said forms at the site of the pouring operation. This is usually done at a great expense. Moreover, after the forms have been used they can not be reused.

Accordingly, it is an object of this invention to provide a system of wall forms for use in building operations, wherein it is possible to erect said forms with a minimum of labor and skill, and at the same time, make it possible to reuse the forms repeatedly.

Another object of this invention is to provide interchangeable forms and form components for the assembly of a structure as desired, without limitation as to the shape or size of the pouring operation.

A feature of this invention is its novel, simplified structure, whereby persons not highly skilled, may assemble satisfactory wall forms.

A further feature of this invention is its tie constructure, which enables the person erecting the forms to slip the ties through the wall forms after they have been set in place.

Another feature of the present invention is its novel waler hook assembly, whereby the wall forms may be lined up and securely held in place.

A further feature of this invention is its key and wedge member, which provides a plurality of interchangeable fastening means adapted to the various securing requirements inherent in erecting wall forms.

The invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming a part hereof, is illustrated one form of embodiment of the invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a view in rear elevation, showing the assembled wall forms, according to this invention.

Figure 2 is a vertical section, taken on line 2-2 of Figure 1.

Figure 3 is a view in perspective, showing the tie and waler securing mechanism, according to this invention.

Figure 4 is a view in perspective, taken from the other side of the assembly shown in Figure 3, and somewhat enlarged.

Figure 5 is a view in perspective, showing two key and wedge members in a somewhat exploded relationship to each other.

Figure 6 is a view in perspective, showing a tie member, according to the present invention, and the associated securing means attached thereto.

Figure '7 is a view in perspective, showing the manner in which adjacent panels are held together by the key and wedge member of the present invention.

Figure 8 is a view in rear elevation, showing the manner in which wall forms may be attached, one upon the other, by means of the convenient key and wedge member.

Referring to the drawings, and particularly to Figures 1, 2 and 3, it! indicates a panel face formed from wood, metal or other suitable material, to the rear of which is attached a frame ll. The frame II is recessed at suitable intervals along the edge thereof, as indicated at H. The recess i2 is adapted to receive a tie member [3 therein. The tie member l3, when inserted in the recess i2, forms a flush surface with the edge of the frame ll. Frames may thus be placed adjacent one another, as shown in Figure l, without interrupting the uniformity of the pouring face. The tie member [3, best shown in Figure 6, comprises an elongated fiat bar [4, having weakening notches l5 spaced from the end thereof.

Horizontal rectangular slots 16 are provided in the bar M at a point between the weakening notches l5 and the ends of the said bar 14. The slots l6 are adapted to receive a wedge therein, for purposes hereinafter more fully described. The tie bar I4 is also provided with a hole ll intermediate the slot 16 and the extremity of the said bar. This hole i1 is adapted to receive therein a waler hook [8, the function of which is hereinafter more fully described.

Figure 5 illustrates the novel key and wedge structure is, which forms an important part of the present system of forms. The key and wedge structure I9 comprises an elongatedflat member having a taper 26 on one portion thereof, and an open slotted extension 2! projecting at right angles from the upper portion of said key and wedge member H. The opening 22 provided in the projecting part 2 l, is adapted to receive therein the tapered portion 20 of an identical wedge such as is shown in Figure 5. Thus, when panels are placed adjacent one another, they may be quickly and firmly held together by the wedges.

The tie bar It and the waler hook l8, together and wedge members with the key and wedge assembly 19, co-operate to form a securing means, best shown in Figures 4 and 6, whereby the walers 24 are held against the frame ll of the panel in order to align said panel. A somewhat U-shaped clamp 25 is also employed in this assembly. The U-shaped clamp 25 hooks over and under the waler 24 and is provided with an opening 26 therein, said opening being adapted to receive therethrough the waler hook 18.

As will be seen from an examination of Figure 2, the walls of the frame I I are provided with rectangular openings 2! therein. The openings 21 are also adapted to receive therethrough the key and wedge assembly l9, in the manner shown in Figures 3 and 7. When it is desired to extend the height of the wall frames in order to pour a higher structure, the frames may be placed one upon the other, in the manner shown in Figure 8, whereupon the openings 21 will be in alignment. between adjacent frames. The key l9 may then be thrust through the openings 21, in the manner shown in Figure 8, so that the open projecting part 2| extends downwardly through the frame. A separate wedge member l9 may then be thrust through the open slot 22, in the manner shown in Figure 8, to secure the adjacent frames together.

From the above description, the construction of a form by the use of the present system, becomes apparent.

It is merely necessary to place the forms adjacent one another in the manner shown in Figure .1, until they extend for the proper length of the wall which it is desired to pour. nd set of panels may be set up in spaced relationship to the first, as-shown in Figure 2. The panel faces I0 should then present a uniform surface, facing toward each other, upon which the poured material will come to rest. Tie bars [3 may then be slid through the notches I2 in the frames and allowed to project a shortdistance beyond the panel frames, as shown in Figures 2, 3 and 4. Thewaler members 24, which may be either of steel or wood, are then placed upon and underneath'the projecting portion of the tie bars I3 and held-thereon by means of the clamp member 25.

The waler hook I8, which has been thrust through the clamp 25, as shown in Figure 6, is provided with a loop 28 upon the end thereof. This loop 28 is adapted to receive one of the wedges I9 therein. When the wedge I9 is driven down through the loop 28, it tightens the clamp upon the waler 24 in such a manner as to secure them in place and align the panel. Wedges l9, when used for this purpose, may be provided with a spot of weld 30 to prevent them from becoming detached from the assembly at any time.

Where panels terminate, the assembly shown in Figure 3 may be used. This locking means comprises passing'a wedge l9 through the opening 16 in the tie, and also through "the opening 21 intheframe II. A second wedge may then be used to secure the tie to the side of the frame, as shown in Figure 3.

- When itis desired to add a second row of frames upon the first, the procedure shown in Figure 8, and previously described, is followed through. Itis within the purview of this invention to provide panels which are curved, angular, or having various architectural shapes, to facilitate the pouring of any .desired form. However, in all theseshapes, .the fundamental system of using the tie barskeyand wedge members, waler hook A sec- 4 and clamp, together with the novel notched panel frame, will be inherent.

In stripping the present system of forms, it is merely necessary for a workman to employ a hammer to drive the wedges out of their various receptacles, and take the form apart, without damaging said form. It is also possible to leave a series of panels in assembled relationship, and lift the entire assembled panel for reuse upon another portion of the construction operation, without the necessity for disassembling and reassembling said panels. This feature of the present invention will greatly reduce building costs.

After the wall has been poured, the central portion of the tie member I3 will be embedded withinthe concrete. However, by means of the weakening notches IS, the ends of the said tie member may be broken off, so that the final poured wall will present a flush or uniform surface.
