SUPPORT AND TIE FOR CONCRETE-REINFORCING RODS.

Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed April 3, 1914. Serial No. 829,245.

To (ZZZ whom it may concern: Be it known that I, Gnoncn R. ScHonN- THALER, a citizen of the United States, residing at the city of Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Supports and Ties for ConcreteReinforcing Rods, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figures 1 and 2 are perspective views of a combined support and tie of my improved construction. Fig. 3 is a vertical section taken through the center of the support and tie, and showing the same combined with a pair of crossed reinforcing rods. Fig. 4 is an elevational view of the device applied to a pair of crossed reinforcing rods, and showing one of said rods in section. Fig. 5 is a sectional view of a modified form of the clip. Fig. 6 is a perspective view of a modified form of my improved device, the same being adapted to support a single reinforcing rod. Fig. 7 is a sectional view taken through the center of the form of device seen in Fig. 6, and showing its application to a reinforcing rod. Fig. 8 is an elevational View of the form of device seen in Fig. 6, and showing its application to a reinforcing rod. Fig. 9 is a perspective view of a further modified form of the device. Fig. 10 is an elevational view of the form of device seen in Fig. 9, and showing its application to a reinforcing rod.-

My invention relates generally to reinforced concrete construction, and more particularly to a combined support and tie for the metal rods used for reinforcing concrete structures, such as floors, roofs, ceilings, walls and the like.

It is the present practice to utilize reinforcing rods in concrete construction, and where these rods are crossed it is essential that the same be tied together, and further that in the construction of floors, walls and the like, it is essential that the reinforcing rods be held above the form or away from the side of the mold onto which the concrete is poured so that said rods will be embedded in the concrete the required depth to properly reinforce it.

It is the principal object of my invention to provide a comparatively simple, cheap and effective support and tie which can be readily applied to reinforcing rods at the points where the same cross, and which support and tie when properly applied rigidly connects the rods and holds the same in the desired position while the concrete is being poured over and around said rods.

With the above and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

As shown in the drawings, my improved support and tie is constructed from a single piece of sheet metal stamped or out by suitable dies to proper shape, and the main body portion of the device comprises a pair of parallel legs or uprights 10, which when the device is in use, occupy substantially vertical positions as seen in Fig. 3. The upper ends of these legs or supports are extended as designated by 11 to form fingers or prongs which, when the device is applied for use, are bent downward over the upper one A of the reinforcing rods. ee Fig. 3.) The lower portions of the legs or up rights 10 are united by a transversely disposed integral member 12, the upper edge of which forms a seat for the lower one B of the reinforcing rods. The metal between the lower portions of the legs 10 and below this transverse member 12 is bent upward at an angle of approximately 45 relative to a vertical plane to form an inclined strut or support 13 between the lower portion of the transverse member 12 and the underside of the lower rod B. The upper end of this strut or support occupies the same horizontal plane with the upper edge of the member 12, and thus an additional transverse seat is formed for the lower one of the reinforcing rods, said additional seat being arranged at a substantial distance from the seat formed by the upper edge of the transverse member 12.

Formed integral with and extending upwardly from the lower ends of the legs or uprights 10 is a pair of inclined members 14-, the upper ends of which occupy positions at the sides of the lower one of the bars when the device is positioned for use, and uniting the central portions of these members 14- is a transverse supporting member 15, the upper edge of which forms a seat for the lower reinforcing bar, and which seat is in horizontal alinement with the the members 14: positioned on the sides ofthe lower one of the reinforcing rods maintainsthe device in proper vertical position, and prevents the device from swingingup or twisting when the portions 11 are bent downwardly over the upper one of the re-' inforcing rods.

The upwardly bent member 13 performs the functions of a strut between the lower rod and the lower portions of the legs 10 and prevents the device from rotating or toppling over when said device is subjected to forces operating in the general direction of the arrows a, Fig. '3.

The upper edges .of the members 12, 13 and 15 .form three separated transversely disposed seats for the lower rod B, and for this reason the device will maintain its proper relative position on the rods even though the same be shifted in a direction parallel with the lower rod. The strut member 13 also transmits a portion of the load carried by the device to a lower center of gravity than where said load is applied directly to the seat formed by the upper edge of the transverse member 12.

In the form of device illustrated in Fig. 5, the strut member 13 is dispensed with,

and in its place a horizontally disposed, sup

porting arm l?) projects outwardly from the upper portion of transverse member 12, and in effect, this arm 13 performs the same functions as the strut 13.

The form of device illustrated inFigs. 6 to 8 inclusive is particularly designed for supporting a single reinforcing rod, and in this construction one of the members 11 is out off adjacent to'the transverse member 12 and the'opposite member is extended upward a sufficient distance to. form a short arm 11 which is adapted to be bent downward over the supported reinforcing rod, as shown by dotted lines in Fig. 8.

Practically the same construction is carried out in the forms of devices illustrated in Figs. 9 and 10, and inthis form of device, the arm 11 is bent a quarter of a'turn so as to lie flat on top of the reinforcing bar when bent downward thereonto.

It will be understood that in the modifications shown in Figs. ,6 and 9, thearms 11 can be, if desired, extended upward from either one or both ends of. the transverse member 12.

A combinedtie and support of my improved construction is comparatively simple, can be cheaply manufactured for the reason that it can be stamped out and bent to proper shape with one operation of a die and former, and when the device-is properly applied to reinforcing rods, the same are firmlytiedto each other and supported in substantial manner the required depth above the form or false work on which the concrete is poured.

It is obvious that slight changes in the size, form and construction of my improved support and tie can be made without depair of upright members, a transverse mem- 'ber connecting the lower portions of said upright members, a supporting member projecting upwardly from the-lower portion of the transverse member, inclined members projecting upwardly from .the lowerends of the upright members, and a transverse member between the central portions of said inclined members.

2. A device of the class described constructed of sheet metal and comprising a pair of upright members, a transverse member connecting the lower portions of said upright members, a supporting member proj ecting upwardly from the lower portion of the transverse member, inclined members projecting upwardly from the lower ends of the upright members, a transverse member between the central portions of said inclined members, .and the upper edges of which transverse members and upwardly projecting inclined member occupy substantially the same horizontal plane when the device is applied for use.

3. In a device of the. class described, a pair of vertically disposed members, a transverse member connecting the lower portions of said vertically disposed, members and forming a seat for a reinforcing rod, an inclined member projecting upwardly from the lower portion of the transverse member and forming a support for the, lower one of the rods to which the device is applied, and an inclined, member extending upwardlyv from the lower end of the device, the upper portion of which member is adapted to engage the sidesand undersideof the lower one of the rods to which the device is applied.

4. Ina device of the class described, a pair of vertically disposed members, a transversely disposed member connecting the lower portions of said vertically disposed member and forminga seat for a reinforcing rod, and a pair of. inclined supports extending upwardly from the lower portions ofthe uprights, which inclined supports provide seats for the lower one of the rods to which the device is applied, said lastmentioned seats being on opposite sides of the first mentioned seat.

5. In a device of the class described, a

pair of vertically disposed parallel members, a transverse member connecting the lower portions of said vertically disposed members, a support extending upwardly and outwardly from the lower portion of said transversely disposed member, and a substantially H-shaped member extending upwardly and outwardly from the lower ends of thevertically disposed members.

7. In a device of the class described, a pair of vertically disposed parallel members, a transversely disposed member uniting the lower portions of said vertical member and forming a seat for a reinforcing rod, a tongue projecting outwardly from said transversely disposed member and forming a reinforcing rod seat and support, and an inclined leg projecting upwardly from the lower ends of the vertically disposed members on the opposite side from the tongue, the upper end of which inclined leg forms a reinforcing rod seat which is substantially in horizontal alinement with the first mentioned seats.

8. In a device of the class described, a pair of vertically disposed parallel members between the lower portions of which is formed a seat for a reinforcing rod, a tongue projecting outwardly from said seat to form a reinforcing rod seat and support, a pair of inclined members projecting upwardly from the lower ends of the vertically disposed members, and a transverse member between the upper portions of said inclined members, which last mentioned transverse member constitutes a seat forthe reinforcing rod which rests upon the first mentioned seats.

9. A device of the class described comprising a vertically disposed member, the upper portion of which is slotted to receive a reinforcing rod, the lower end of the slot in said member constituting a seat for said rod, a tongue projecting outwardly from the device below said seat to form a rod support, and an inclined member projecting upwardly from the lower end of the first mentioned member on the opposite side from the tongue, the upper end of which inclined member is adapted to bear against the underside OI the rod to which the device is applied.
