HARRY O. DAVIDSON, .OF CLEVELAND, OHIO, ASSIGNOR TO THE HYDRAULIC PRESSED STEEL COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.
SUPPORT FOR CONCRETE FORMS.
Application filed November 21, 1919. Serial No. 339,581.
I To all whom it may concern:
Be it known that I, HARRY O; D-AvIDsoN,
a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and 'Stateof Ohio, have invented a certain new and useful Improvement in Supports for Concrete Forms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawmgs.
This invention relates generally to a support for flat slab concrete forms and more particularly to one composed of sheet metal and so constructed that the support as a whole can be quickly and easily arranged for the purpose of supporting the slab pan thereonand one in which certain parts thereof can be quickly and easily removed in order to release said pan. Another object of the invention is to provide a support which can be arranged at any point along the joist and brought into supporting engagement with the pan at any portion of the side thereof.
With these objects in view and certain others whiclr will become apparent as the description proceeds, the invention consists in the novel features of construction of the various parts and in the manner of combining or arranging said parts into cooperative relation, all of which will be fully described hereinafter and set forth in the appended claims.
In the drawings forming a part of this specification, Fig. 1 is a sectional view partly in elevation showing the practical application of one embodiment of my invention; Fig. 2 is an elevation taken on the line 22 of Fig. 1; Fig. 3 is a detail'perspective view of one of the stirrups; Fig. 4
is a detail perspective view of one of the supporting arms or brackets and Fig. 5 a sectional elevation showing a slightly modified construction.
In carrying out my invention I employ a plurality of joists A which are arranged in parallel relation and spaced apart a distance determined by the width of the flat slab pan B which is to be arranged betweensaid joists and supported therefrom. Sheet meta stirrups C are shaped to straddle said.
joists and are arranged thereon at definite oints and the legs of said stirrups are Bowed outwardly as shown at C..
In connection with each stirrup I employ a pair of oppositely disposed supporting arms or brackets D made also of sheet metal, each supporting arm or bracket comprising a base plate which is slotted vertically as shown and central upper portions projected upwardly providing a vertical finger D and end portions turned horizontally providing supporting fingers D A central portion is bowed outwardly as shown at D and the intermediate end portion is bowed inwardly as shown at D thereby providinga loop D in the base plate and it will be noted that the upper half of the base plate is bent outwardly as shown at D in order to space the fingers D and D some distance from the upper end of the joist and, if desired, strengthening corrugations D may be made at the juncture of the horizontal fingers D and the inclined portion D9. The bowed portion C of the stirrup leg is adapted to fit into the'bowed portion D of the base plate and a locking wedge E is then inserted through the loop D and within the bowed portion C of the stirrup leg, thereby securely looking the supporting arm to the stirrup. The flat slab pan B is arranged upon the supporting arms, the sides thereof contacting with the vertically positioning fingers D while the bottom flanges or edges rest upon the horizontal fingers D and in order to prevent any movement of said pan I employ a plurality of spring clips F which are sprung over the bottom flanges of the pan and the horizontal supporting fingers D as most clearly shown in Figs '1, 2 and 5'.
After the pans have been properly positione'd, filling strips Gr are arranged upon is'considerably longer than the finger D ;ex-
tending practically to the top of the pan as most clearly shown. This provides an additional element of safety in the connection of the pan with the supporting arms.
In operation the stirrups are placed upon the oi'sts and the supporting arms or brackets are attached thereto on opposite sides by means of the locking wedges and the pans are placed upon the supporting arms and the spring clips fastened to the pan and arms to connect said parts together. The filling strips are then forced in, completing the unbroken slab form throughout the given area.
After the concrete has been poured and permitted to set for a definite period of time, say twenty-four or forty-eight hours, the fiat slab pans can then be removed and used again where desired, and in order to remove said pans it is only necessary to disconnect the spring clips, knock out the wedges and the supporting arms can be withdrawn from the stirrup and the pan is then free to be taken down, the filler strips remaining supported upon the joists.
A form support constructed as shownherein and described is simple in operation and inexpensive in manufacture and fur thermore can be arranged at any point desired upon the joists'in order to engage the pan at any desired point-s.
Having thus described my invention, what I claim is 1. The combination with a stirrup each leg of which is bowed, of a pair of supporting arms comprising a looped base plate provided with upwardly and outwardly projecting overlapping portions and the locking member longitudinally inserted between said overlapping portions.
3. The combination with a pan, of a stirrup, and a support detachably connected to said stirrup, said support having vertical and horizontal fingers at its upper end and with which the pan contacts.
4:. The combination with a stirrup having a bowed portion, of a supporting arm having a looped portion adapted to register with the bowed portion of stirrup, a wedge engaging said bowed and looped portions, the'upper end of said arm having a vertical and a horizontalfinger, and a pan engaging said fingers. 4
5. The combination with a pan having bottom flanges, of supporting arms having fingers upon which said pan rests, means for supporting said arm, and clips adapted to engage said fingers and pan flanges as set forth. a
In testimony whereof, I hereunto affix my signature.
HARRY O. DAVIDSON.
