Application January 24, 1955, Serial No. 483,509 2 Claims. (Cl. 25-131).

My invention relates to improvements in concrete form frames, ties, clips and wedges, and more particularly to a novel arrangement and combination of the same.

This application is a continuation in part of my copending application, Serial No. 174,613, filed July 19, 1950, for forms, ties and clips for concrete work, and which has become abandoned since the filing of this application.

An object of the present invention is to provide concrete form frames, ties, clips and wedges in combination, which provides for quick, ready, and easy assembly of the concrete forms for receiving poured concrete and ready removal of the forms after the concrete has properly set and with a minimum damage to the forms so that they can be used and reused with a maximum life.

Another object of my invention is to provide concrete form assemblies of a type which provide for a relatively rigid construction when the forms are in use.

Another object of my invention is to provide a clip and tie rod assembly cooperating with the concrete form frames and construction carried thereby, so as to insure precise alignment of the various concrete form members providing the completed concrete forms.

Another object of my invention is to provide a concrete form assembly means so that units of various dimensions can be combinedto form a. concrete form of desired dimensions for a particular construction job.

A specific object of my invention is to provide flanges carried by concrete forms having clip receiving openings therein and clips, tie rods, and wedges of a construction so that upon placement of the clips and appropriate utilization of the wedges, the concrete form will be aligned and secured together in a way to provide a concrete form of precision fitting and. which can be readily disassembled after the concrete has set-and the forms can be reused. Other objects and advantages of my invention .will become apparent as the description of the same proceeds and the invention Will bebest understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of the specification, with the understanding, howover, that the invention is notto be limited to the exact details of construction-shown and described since obvious modifications will occur to a person skilled in this art. s 1

My invention permits the utilization of standard size frames in erecting the walls of a concrete form and which standard size frames may be of given sizes such as 2' x 3 or 2' x 4'. Also my invention readily lends itself to the use of standard interior corners and by way of example such corners may be 4" x 4". If such standard interior corners are used, the height thereof will, of course, depend upon the height of the wall thatis to be made of concrete between the concrete forms. As to the outside corner, the same will vary and comprise two frame members of widths depending upon the thickness of .the concrete wall and, of course, the height will depend upon the desired height of said concrete wall.

Referring now to Fig. 1 of the drawings, I have shown a combination of various standard size frames wherein the concrete frame assemblies have panels 20 and 21 of a given length and Width, as 2' x 3', whereas the panel 22 will be 2' x 4. In Fig. 2 of the drawings I have shown an inside corner 23 and by way of example the width of the walls of the same will be 4". In the event that the wall being formed between the concrete forms is 8" thick, then the width of the panels 24 and 25 will be 12". Thus I am able to.utilize a standard inside corner construction 23 of given dimensions and the panels 24 and 25 may be determined in their width according to a particular thickness of wall desired and the standard dimensions of the inside corner 23.

Each of the panels (20, 21, 22, 23, 24, and 25) is framed along its marginal portions with an angle iron, as the angleirons 26 and 27 framing the panel 22. The angle irons 26 and 27 have one flange disposed parallel to the marginal edgesof thepanel 22 and are recessed back from said marginal edges approximately when ties 28 are employed having a diameter of approximately A Also each of the panels, as 22, is provided with a semi-circular recess 29 and which recess 29 has a diameter of Thus the flanges 30 are parallel to oppositely disposed marginal edge portions of the panel 22 while the flanges 31 are parallel. to the other two marginal portions of said panel 22. The remaining flanges 33 and 32 of the angle irons 26 and 27 are flush with and secured to the panel 22 by any suitable means, as split rivets .33 which do not project completely through panels 20 (Fig. 3).

The flanges 30 and 31 which project away from the panel 22 are each provided with a plurality of clip receiving openings 34. If standard frames are to be employed, then a standard spacing between clip receiving openings 34 is necessary to provide for securing the flanges of different frames together and to provide for matchingof the clip receiving openings. Thus by way of example, I have employed clip receiving openings 34 on 12'. centers and with the said clip receiving openings spaced 6" away from the ends of the flanges 30-31. Obviously the spacing between centers .and the spacing between the end and a clip receiving opening may be varied as long as a standard is employed which will permit combined use of various size panels such as 2' x 3'; 2. x 4' and the like. Also a matching pattern may be asaaaae employed where panels of non-standard size are used such as used in connection with outside corners as in connection with panels 24 and 25. Also the length of a concrete wall which is tobe built may not be a length whichisin evenfeet and hence some non-standard frames may.

employed to erect vthe concrete forms employed in the pouring of such a wall. Again the clip receiving openings 34 can be properly spaced in flanges of such a non-standard frame panel so the openings will match with the clip receiving openings 34 in a standard. panel.

,Referringnow to Fig. 3 of the drawings, there is shown my apparatus for securing portions of two frames to: gether. Thus by way of illustration, I have shown the panel frame, 20, as well as the panel frame 21, in spaced relation. secured a fragment of an angle iron 32.-31 and with the flange 32 in each instance secured to the particular panel frame involved. .Also in each instance the flange 31 is recessed inwardly of the edge portion of the panel, such as edge 35 of panel 20 and edge 36 of panel 21. This will leave an overhang of the panels 20 ,and 21 past the flange 31 of each of the said panels by. approximately one-half the diameter of the tie rod 28 which is being employed and as the tie rod 28 is assumed to have a diameter of the overhang will be and thus the diameter of the recess 29 will be By thisoverhang arrangement, when an angle iron 31-32 of the panel 20 is urged relatively toward an angle iron 3132 of the panel 21, there will be an edge abuttment relation between the edges 35 and 36 of the panels to insure a tight seal and at the same time there will be a recess, formed by the two halves or recesses 29 in the edges 35 and 36 of the panels 20 and '21, to accommodate the passage therein'of the tie rod 28. The construction thus just .de-

scribed obviously -,will be present wherever a clip recesswedge ,42 is shown relatively as being vertical and the endwall 41 inclines inwardly and downwardly toward the end wall 43. Thus the end wall 43 of wedge 42 may rest against the inside surface of the flange 31 as shown in Figs. 4 .and ,7 of the drawings, and the end wall 41 of said 'wedge42 will rest against the inside fsurface of the end wall ,40.

The other end wall of the clip 37 is formed of two segmentary walls 44 which are separated by a V-slot 45 which terminate preferably in a semi-spherical concave depression 46in the side walls 38 and 39 and of a diameter equal to that of the tie rod 28. Each tie rod 28 has provided thereon a boss 47 of a diameter and thickness to pass through slot 45 and permit the rod portions 28 on either side thereof to abutt against a concave depression 46 in the side walls 38 and 39. Also said diameter should besnfflcient to provide adequate frictionalengagementbetween the boss 47 and wedges 42 to limit longitudinal movement of a tie rod 28, see particularly Fig. 7.

Assuming the parts are in the position shown in Fig. 3 of the drawings, then the boss 47 will be inserted through the slot 45 until the portions of the rod 28 on either side of the boss'47 engage with the concave depression 46 in the side Walls 38 and 39 of the clip 37 and then the segmentary walls 44 will-be inserted through a clipreceiving opening-34 in a flange 31 of the frame section 21 which is-tothe right in Fig. 3 of the drawings and then a wedge 42 is inserted in place to obtain the positions shown in Fig. 4 and with the inclined wall 41 engaging the inside wall; of the segmentary walls 44 as well as the boss 47. Thenthe wedge canbe driven into place and the end wall To each of the panel frames 20 and 21 is 40 will be in position to be urged through an aligned clip receiving opening 34 in the next wall section which is to be secured in place such as the wall section 20. After the various end walls 40 of the various clips 37 are aligned in place in clip receiving openings 34 of the next wall section, such as the wall section 20, then an additional wedge 42 will be driven in place in each instance and with the end wall 43 of the wedge 42 contacting the boss 47 and the other end wall or wall 41 of thewedge. 42 contacting the inner wall of the end wall 40.

By way of further explanation, an end portion of a tie rod 28 is first inserted in'place relative to a clip 37 by I inserting the boss 47 through the slot 45 of a clip 37 and until portions of the rod 28 adjacent the boss 47 rest in the concave depressions 46 in the side walls 38 and 39 of said clip 37. Next, the segmentary walls 44 are inserted through a. clip receiving opening 34 and then the tie rod portions adjacent the boss 47-will-restagainst the outside face of flange'31 and with a portion ofthe tie rod 28 in the recess 29-see particularly Fig. 4; Then when a wedge 42 is inserted in the opening in the clip 37between side walls 38'and 39 and on the inside faceof a flange 31, the tie rod 28 will be supported against the outside face of a flange 31 while the wedge 42 will have its surface 43 abutting against the inside surface or-face of aflange 31 so that the said flange 31 will-support a clip 37-and at the same time the-wedge42will-contact a boss 47 on a tie rod 28 and thus limit longitudinal movement of a-tie rod 28.

After a clip 37 has been supported by a flange 31(as is best shown to the right in Fig. 4 of the drawings), then the said clip 37 is available for insertion thereover'of a clip receiving opening 34 of the next panel tobe secured tothe first mentioned panel. In other words, as shown by way of example in Figs. 3 and 4, the first assembly involves-the change between-Figs. 3 and 4 of the drawings and thereafter a given panel, as panel 20, can be readily inserted by passing the clip receivingopening 34 inthe-flange 31 of said nextpanel 20 over the end portion involving end wall 40 of a clip (secured to a flange 31 of the panel 21) and after said movement, then a wedge 42 can be inserted in the opening between the side walls 38 and 39 and end wall 40'of a clip 37 which projects through the clip receiving opening 34 in' the flange 31 of the panel 21. Again a wedge 'is inserted in placeand with the-portion 43 adjacent the inside wall'of;

the flange 31 and with the portion 41 adjacent the inside wall of the wall'40.

- Also preferably the outside configuration of the clip-37 formed by side walls 38 and 39 is such that the same matches rather snugly within the inside configuration of an opening 34. This provides for relative sidewiseor lateral movementof wall sections, as'20 and 21, so that the concrete contacting surfaces of the walls of-the panels 20 and 21 are aligned to provide for a suitable concrete engaging face which provides acontinuous surface on the poured concrete wall.

The material to be employed in-connection with the panels 20 and 21 and other panels employed in my invenmeans'48- are employed to eliminate the possibility of sagging of the panels, as panels20 and 21-, between angle irons'26 or 27 (see Fig. I). Said reinforcing'meansmay be in .the form'of angle irons, as shown, andthe same may the connected with angle irons 26 or '27and' may not -be so-connected, as shown-(Fig. 1

The wall sections may be set'up-commencingfrom the right and progressing toward the left, as shown in Figs. 3 and 4 of the drawings, but obviously the erection of the wall sections can start from the left and proceed to the right with devices of my invention. In such latter case, the tie rod 28 is first inserted with the boss 47 passing through the slot 45 until the portions of the tie rod 28 adjacent the said boss 47 engage with the depressions 46 and then the end portion of a clip 37 comprising segmentary walls 44 is inserted first into the clip receiving opening of the Wall which is on the starting side. For example, if the starting side is to the right, then the apparatus may be assembled as is illustrated in connection with Figs. 3 and 4. If the starting side is to the left, then the clip 37 is rotated 180 over the position shown in Fig. 3 of the drawings and placed in position relative to the tie rod 28 and the clip 37 and tie rod 28 are moved toward the left of said figure and the end portion (segmentary walls 44) is inserted in a clip receiving opening 34 in a flange 31 of a panel section 20 and then the wedge 42 is inserted properly behind the flange 31 carried by the wall section 20. The mode of operation has been described primarily in connection with Figs. 3 and 4 and it is believed that the further showing of the same parts in Figs. 5-7 inclusive aids in the better understanding of the complete mode of operation of the construction illustrated and described.

In a general way, I have thus provided a concrete wall form which will comprise various face members, as the surface of panels 20, 21, and 22, or the surface provided by the inside corner 23 or by the panels 24 or 25 forming the outside corner. Also the concrete wall form may comprise face members of standard sizes or nonstandard sizes. Also I have provided a flange as the projecting flanges 30-31 which project away from a face member and the said flanges have therein clip receiving openings 34. Preferably each of the clip receiving openings 34 is rectangular in shape to receive the clip 37. A rectangular opening is the most eflicient size to employ. Also each clip member 37 is provided with a slot 45. Preferably the said slot is V-shaped and with the large opening of the V in the end wall 44-44. Next the said V-shaped slot preferably terminates in a concave recess portion or depression 46. The outside sectional size of the clip which is normal or at right angles to the side walls of the clip 37 is such to snugly interfit with the clip receiving opening 34 in a flange 30-31. By having the said portions thus snugly interfit, the panels, as panels 20-2122, will be aligned to provide a smooth concrete wall form surface contacting the poured concrete. The tie rod 28 is provided having bosses 47 thereon and the bosses are of a size to be projected through the slot 45 of clip 37 until the portions of the tie rod adjacent the said bosses 47 rest against the apex of the slots 45 and preferably against the concave depression 46 in the side walls of the clip. The wedge means 42 are provided and preferably the said wedge means 42 are provided with the end walls 41 and 43 thereof tapering to a common point so that an inclined wall 41 will rest against an end wall of the clip and a straight end wall 43 is provided to rest against the inside surface of a flange 30-31.

Obviously changes may be made in the forms, dimensions, and arrangement of the parts of my invention without departing from the principle thereof, the above setting forth only preferred forms of embodiment of my invention.
