JUNCTION GL1]? AND SPACER FOR REENFORCEMENTS.
Application filed December 6, 1926. Serial No. 152,893.
My invention relates to concrete reenforcement, and particularly to means for en gaging and holding crossed bars and for spacing apart a double series of such bars.
The invention comprisesessentially a rigid spacing element preferably composed of sheet metal or similar material, together with a pair of spring arms secured at one end of the spacer and adapted to pass over one crossed bar and to be hooked around over a parallel crossed bar in the adjacent series.
The foremost object in the proposed constrnction is to simplify the steps of mannfacture and installation and to assure rigidity and firn'iness in the performance of the required duties.
The invention will be more readily understood by reference to the accom ninying drawings, in which;
Fig. 1 is an elevation partly in section showing a pair of devices constrnctedin accordance with my invention, the two devices varying somewhat in one feature;
Fig. is a sectional view on the line 2-2 of Fig. 1;
Fig. 3 is an end view of the device shown at the left hand part of Fig. l, and;
Fig. l is a plan view of the construction shown in Fig. 3;
In the drawings, I have shown parallel. spaced apart bars or rods A-B and parallel, right-angnlarly disposed rods or bars 7 D. It is intended when installing the leenforcement in roadways to assemble a unit such as shown in Fig. 1, and then to lift the assembly and place it in position on the prepared roadway ready for the pouring of the concrete. In the event that no means are provided for retaining the reenforcing unit in spaced relation above the soil, it is customary to pour a layer of concrete then to place the reenforcement thereon, and then pour the remainder of the slab. I have, however, provided in the device here disclosed, means for spacing the unit above the soil so that the reenforcement may be assembled and placed in position before any pouring is done. This reduces the labor cost and enables the complete pouring of a slab in one operation. A device for accomplishing that result is shown at the left hand portion of Fig. 1, and in Fig. 1
The device illustrated at the right hand end of Fig. 1 comprises sheet metal spacing element having a central rib, 10, and side flanges, 11. The upper end ofthe member is cut diagonally to provide a deep seat forthe bar ll, while at the lower end a V-shaped notch. 10, is cntin the rib, '10 and the over hanging portion 10 is bent backwardly until the flanges 13, are in contact with the flanges, .11. This provides a broad and deepseat for the bar A, and insures rigidity and stability of the structure. At the upper end, the flanges 11 are extended andbent over, as at 19, to overlie the crossed barC. This serves as a means tor holding the bar against movement in two directions. At the lower end, the flanges 13, at the bend therein constitute the fastening means for the horizontal portions, 1-1 of the spring arms, 15. The upper ends of the arms are rebent toprovidehooks, 16, adapted to be sprung over the bar C.
"the connecting portion between the two arms, 15, is bent in the form of av loop, 17, angularly disposed relative to the portions, lat, and adapted to overlie the bars A, the curved end portions, 18 of the spring arms overlying the bars D. Before installation, the sprin arms, occupy a position similar to that indicated by the dotted lines at the right hand end of Fig. 1. After being placed in position, the arms are swung upwardly into the full line position.
In the construction shown at the left hand end of Fig. l, and in Figs. 3 and 4, the parts just described are identical, and no further description is considered necessary. However, the flanges, 11 are extended laterally and downwardly to form legs, 19, the ends of which are extended horizontally to form. feet, 20. The length of the legs is such that the reenforcing unit after having been assembled, may be lifted and placed in position on the prepared soil, beneath the proposed roadway, and the entire slab of concrete be poured. It may be found suiticient to employ the device shown in Fig. 3 at some of the intersections, the remainder of the intersections being held by the device shown at the right hand end of Fig. 1, or all of the devices may be as shown in Fig. 3.
The practical advantage of the spacing and holding device will be apparent to those accustomed to the use of such articles; the assembly of a reenforcing unit may be very quickly and conveniently accomplished, with out the use of special tools, and without the use of separated or separable parts. The construction is of extremely simple form and may be economically constructed.
Modifications in the form and arrangement of parts may be made Without departure from the spirit of my invention.
I claim:
1. In combination, a sheet metal spacer having a rib and providing a seat for a bar ateach end, and a spring arm pivoted at one end of said spacer and adapted to overlie a crossed bar near its pivot end and to book ever a second crossed bar at the opposite end 01" the spacer.
2. In a device of the class described, the combination of a rigid member providing av seat at each end for parallel spaced bars, and means for holding spaced parallel crossed bars said means including a spring arm adapted to be bent around one of said crossed bars and to hook over a spaced crossed bar.
In combination, a sheet metal spacing member providing a seat at each end for a bar, the seat atone end being relatively wide whereby to insure stability, a spring arm fastened to the sheet metal member at one end and adapted to be bent over a crossed bar at a point near that atwhich said arm is connected to the member, said arm having a hooked end adapted to be sprung around a gpaced bar at the opposite end of said meni- 4:. In combination, a sheet metal spacing member having a rib and flanges, said member providing a seat at each end for spaced parallel bars, the flanges at one end being projected beyond the rib to overlie a crossed bar, a spring arm connected to the member at one end and adapted to engage a crossed bar and to be hooked around a crossed bar at the opposite end at the point at which said lastnamed crossed bar underlies said projected flanges.
5. In combination, a rigid sheet metal spacing and supporting member having, a rib and a side flange, the rib ol said member being notched near one end, the overhanging, portion being bent backward until the flanges are in contact, thereby providing a deep, wide seat lTor a bar, the flanges at the opposite end of the member being projected and bent to overlie a bar, and a spring arm coin nected to the member at one end and adapted to be bent and hooked around a crossed bar at the opposite end of the member.
6. In cm'nbination, a rigid, sheet metal spacer providing a seat at each end for a bar, and a pair of spring arms pivoted to one end of said spacer and adapted to engage over a bar at the pivot end and to be hooked over a parallel bar at the opposite end of said spacer.
In testimony whereof l have allixed my signature.
