All@ 21, 1934- MMGREGGR s. ANbERsoN 1,970,547
` Patented Aug. 42l, 1934 UNITED STATES PATENT OFFICE 140 Claims.
The main objects of this invention are to provide an improved panel form for use in the construction of concrete walls; to provide a panel form having a facing of inexpensive material adapted to be readily removed and reversed or replaced when desired, to provide panel forms Of this kind'which are constructed so as to permit any desired number of them to be coupled together edge to edge for buildings. mold of any required dimensions; to provide an improved form of rim adapted to protect the edges of the facing material andalso to serve as a seal for the abutting edges of the panels when coupled; to provide an improved form of tie which serves 'not only as atie and spreader to hold opposed panels in proper spaced relation, but also serves as a lock for temporarily coupling adjacent panels edge to edge in exact alinement; and to provide panel forms of this kind which can be readily set up and dismantled by one unskilled laborer.
An illustrative embodiment of this invention is shown in the accompanying drawings, wherein:
Figure 1 is aside elevation showing one way of coupling ve of the improved panels edge to edge.
Fig. 2 is a fragmentary perspective of an irnproved wall form showing the method of applying horizontal and vertical liners tothe backs of the panels.
Fig. 3 is an enlarged detail partly in section and partly in elevation, showing one method of attaching a liner to the panel frames.
Fig. `4 is a fragmentary perspective of a wall form showing the improved form ties which lock the panels in assembled relation.
Fig. 5 is an enlarged perspective of one of thel improved ties.
Fig. 6 is an enlarged detail showing theimproved method ofapplying the tie to a panel.
Fig. '7 is a detail in section showing the abutting edges of two adjacent panels before they are clamped together, and Fig. 8 shows the same parts after being clamped together by the ties.
The improved panels to which this invention applied are preferably all identical in construction, size, and .shape so as to obviate the necessity of sorting and to facilitate handling and storage of the panels. Y
The panels are rectangular and the width of each is preferably two thirds of its length so that the panels may be joined together, either in the manner shown in Fig. 1, or as shown in Fig. 2, for constructing molds of different heights.
In the form shown, each panel comprises an 55 angle iron frame 1 having anges 2 disposed in a single plane to provide a support for a facing 3 which is detaehably secured to the flanges 2 by bolts 4 or removable rivets, so as to permit the facings to be renewed when necessary. These facings may be made of metal, wood, or any other suitable material.
Disposed at right angles to the flanges 2, are fianges 5 which form the bearing edges of the panels. Formed in these edges 5, are apertures 6 which are positioned so that, when the panels 65 are placed edge to edge, either as shown in Fig.
1 or as shown in Fig. 2, the apertures in the edges of one panel will register with those in the abutting edges of adjacent panels.
Nails .7 or other Wedges may be insertedinto some ,of the registering apertures for interlocking the panels.
The flanges 5 aregdepressed adjacent certain of the apertures to form recesses 8 for receiving tie bands 9 which, as hereinafter described, hold 75 the form sides in proper spaced relation and also serve to interlock the abutting panels vof each form side. y
The panels may -be braced by angle bars 10 which extend across the frame in engagement 30 with therear of the facing.
In order to protect the edges of the facing against injury and also to seal the abutting dges of the panels against the leakage of concrete, each panel has a rim which circumscribes the facing. This rim includes a portion 1l which is clamped between the facing' and the frame by the bolts or rivets 4 and a border fiange 12. The rim is preferably made of sheet metalhaving some resilience so that the flanges 12 Will normally diverge from the facing edges, as shown in Figs. 6\and '7, when Ithe panels are not interlocked.
lWhen the panels are interlocked, the rim flanges 12 are pressed firmly against the facing edges, as shown in Fig. 8. The rim flanges 12 are 95 recessed, as shown at 13, so as to permit Ithe l tie bands to extend between the abutting edges of the panels.
The tie bands 9 are preferably formed of band iron having portions thereof struck out to provide opposite projecting dowels 14 adjacent each end thereof. These dowels are adapted to extend through certain of the apertures in the panel flanges 5 and they are provided with open'- ings or sockets 15 for receiving nails 16 or other 105 Wedges which engage the inner faces of the flanges 5. It will thus be apparent that the tie bands serve to hold the form sides in proper spaced relation to each other and also serve 4to firmly interlock the panels of each form side.
1f desired. the form sides may be further braced by horizontal and'vertical liners 17 and 18, respectiv'ely which are secured to the panel frames by yokes 19 which are provided with hooked ends 20 engaging certain of the apertures 6 of the frames. Blocks 21 are inserted between the base of each yoke and the outer face of the liner. The blocks 21 may be secured to the yokes 19 by nails 22, as shown in Fig. 2, or they may be provided with grooves 23 for receivingthe base of the yoke, as shown in Fig. 3.
To erect a-form of this improved construction, care should be taken to commence with a level base. The panels may be positioned vertically or horizontally or some may be positioned vertically and others horizontally depending upon the height of the wall to be constructed. The tie bands are cut and formed at the factory so that it is necessary to select those of proper lengthV for the particular wall to be built.
In attaching the tie bands, the dowel parts 14 are inserted through certain of the registering apertures 6 of the abutting edges 5 of the panels and the nails 16 are then driven into the sockets 15 for forcing the abutting edges into firm contact, as shown in Fig. 8. In this position, the rims 12 will seal the joints against the leakage of concrete. i
After the lower course of panels has been erected, another course may be built on top of it, either in the manner shown in Fig. 1,l or as shown in Fig. 2.
To insure proper alinement of the panels, the liners may be attached to one side of the form in the manner indicated.
A moldoi this construction is very easily dismantled. The liners are removed and then one' panel at a time may be removed by merely knocking out the nails 16 which hold it in place. When all of the panels have been removed, the extremities of the tie bands 9 will project beyond the concrete wall and these may be cut oi ush with the concrete if desired.
Although but one specic embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown may be altered without departing from the spirit of the invention as dened by the following claims:-
