ALEXANDER 1P. CRARY, OF NEW YORK, N. Y.
STEEL FORM.
Application filediOctober 5, 1921. Serial No. 505,561.
T 0 all whom it may concern:
Be it known that I, ALEXANDER P. GRARY, a citizen of the United States, residing in the borough of Bronx, countyot' Bronx, city and State of New York, have invented certain new and useful Improvements in teel Forms, of which the following is a specification.
This invention relates to concrete forms and has particular reference to that class of forms which employ panels built up to de sired dimensions from units or plates of various sizes bolted together at their adjoining or meeting edges.
An important object of the invention is to provide in a form of the above mentioned class a novel arrangement of bolt-receiving openings in the various size plates employed, whereby, whenever the edges of the plates are brought together-in any relative position, a suflicient number of the openings in the adjoining or adjacent plates will be brought into registration with each other to permit the use of an ample number of bolts to insure an intimate and rigid jointure between the units."
A further object of the invention is to provide in a form of the above mentioned type a means for effectively retaining the panels in their proper'planes when erected or placed in position to receive the concrete.
Another object of the invention is to provide in a concrete form a means whereby protrudingobjects or obstacles, such as electrio conduits and steam lines, may be passed through the form in order that the wall may v be formed or built up around such objects without destroying that particular unit or plate through which the same would ordinarily pass, thus rendering the same unfit for further use;
A still further object of the invent-ion is to provide a novel means for producing a neat and relatively undefined jointure at the meeting faces of a wall.
Other-objects and advantages of the in-' 'vention will become apparent to those skilled in the art when considering the following Figure 4 is an elevation of a wall panel built up of a plurality of wall plates embodying my invention.
Figure 5 is a fragmental sectional view of a form constructed in accordance with my inventlon. i
Figure 6 is a sectional view taken on line 6'6 of Figure 5.
Figure 7 is a sectional view of adjoining plates at the corner of a form having a bevel strip associated therewith.
Figure 8 is a perspective View of a bevel.
strip supporting gusset. Figure 9 is a perspective View of another form of bevel strip supporting gusset. In the drawing the numeral 10 indicates a wall plate or unit comprising a metallic sheet 11 to which is secured at its marginal edge an angle iron frame 12, including end members 18 and side members 14 provided respectively with elongated slots or openings 15 and 16 adapted for the reception of bolts 17, shown in Figure 5 which serve to retain the units or plates 10 in an assembled relation as shown in Figure 4 to form a wall panel indicated as a. whole by the numeral 18. p
In practice I prefer to employ wall plates or units 10 of various widths and lengths,
such as areclearly shown inFigure 4, in
required. But in'orderito be able'to bolt the various sections together in an assembled relation as above referred to without-necessitating a complementary arrangementof all' the bolt holes employed for the reception of the bolts 1'7, I resort to a novel spacing of the bolt holes as illustrated in'Figures 2 and .3 in which the slotted holes at one side of adjacent plates 10 whenassembled to form the panel 18 regardless of the respective positions of the several plates employed.
The panels 18 built up in accordance with my invention are particularlyadapted to be used in what are known as fiat forms, such as are used in sides and bottoms of beams and in side wall and ceiling conorder that I may buildup any size panel struction work, and to illustrate the adaptability of my invention to such work, I have shown in Figures 4; and 5 panels 18 erected and in position for use. For supporting the horizontal panels 18, hereinafter for convenience referred to as the ceiling panel, I employ a plurality of horizontal wood supports, one of which is shown at 19, upon which the several plates or units rest, it being understood that the supports 19 may be retained in position by any suitable means, such for example, as an under-frame, not shown, of any suitable construction. In order to prevent the angle iron frames 12 of the plates 10 from hearing directly upon the supports 19 and sinking into the same to any extent whatsoever as a result of the weight of the panel 18 and the load carried thereby, I employ a plurality of bearing plates, one of which is shown at 2U, upon which the frames 12 rest, the bearing plates being interposed between the supports 19 and the panels 18. In order to retain the panels 18 in position upon the supports 19 I employ a plurality of clips, one of which is indicated by the numeral 21. These clips are adapted to be secured to the supports 19 and extend an appreciable distance above the upper faces of the supports, they being provided at their upper ends with lugs or projections 22 adapted to enter certain slots or openings of those indicated by the numerals and 16.
" dicated by the numeral 23, each lug being secured to the plate or unit frames 12 by means of a screw 24 passed therethrough as shown in Figure 5. The fillers 25 and 27 carried respectively by the ceiling panel and the side wall panel, are fastened to the outer sides of their respective panels in order to give bearing area which is not sufficiently provided by the under edges of the angle frames 12. To the ends of supports 19 and 26, which do not project beyond the limits of the panels, bearing plates 28 are nailed to prevent the edges of the frames 12 from sinking in to the wooden supports 19 and 26 when the panels are loaded with concrete.
In order to produce a beveled corner at the jointure between the side wall and ceiling, or what is known as an internal corner between the meeting wall faces, I provide a bevel strip 29, one side of which is bent into the plane of the ceiling panel 18, whereas the opposite side thereof contacts with the tiller 2?. The bevel strip 29 forms a part of the ceiling panel and is connected therewith by means of a plurality of sheet metal gussets 30, each of which comprises a base portion 31 bent to provide a supporting wing 32 which is welded to the bevel strip 29, the base portion being preferably bolted to the ceiling panel. By somewhat modifying the means above described for producing a bevel jointure at an internal corner, I am enabled to effect a similar jointure at what is commonly called an external corner and to accomplish this I employ a gusset 33 compris ing a base 34: provided with a slot 35, the base being bent at one end to provide a supporting wing 36 which is secured as by welding to a bevel strip 37 The wall panels 18 as shown in Figure 7 are brought together at a corner and between the adjacent frames 12 thereof I interpose an angle iron 38 which is bolted to the frames 12, by means of bolts 39, one of which is passed through the slot of the gusset 33 serving to retain the same in position.
It often happens in construction work that provision must be made to permit such objects as electric conduits and water pipe lines to extend through the section of the form. It is customary to cut an opening in the form to permit the pipe to extend through the same, thus destroying a section of the form. In order to accommodate such objects as electric conduits and the like, 1 employ wood inserts, one of which is shown in Figure 4. and indicated by the numeral 40. In practice an insert 40, through which an opening is cut to accommodate the conduit or water pipe, is substituted for a wall plate 10 at a desired location, it being held in position in the panel 18'between the frames 12 of the surrounding wall plates 5 by any suitable means, such for example, as by nails or screws, not shown, passed through the openings 15 and 16 of the surrounding frames.
Having thus described my invention, I claim:
1. A concrete form panel comprising a plurality of plates, each of which includes a inc frame member provided with openings, the
openings of one frame member being uniformly spaced with respect to each other and having a different spacing to those of the adjacent frame members ofthe adjacent plate, a plurality of the openings of one frame member being in registration with a plurality of the openings of theadjacent frame member.
2. A concrete form panel comprising a plurality of plates, each of which includes a frame member provided with openings, the openings of one frame member being uniformly spaced with respect to each other and having a diifcrent spacing to those of the adjacent frame members of the adjacent.
