(Cl. 'l2-108) 6 Claims.

This invention comprises an anchor bracket for buildings having especial adaptation for use as a combination reinforcing rod supporting bracket, a roof rafter anchor and a floor joist anchor.

It is within the objects of this invention to provide an anchor which may be used in either the roof or the floor, withoutany change in its construction, to supplant the expensive and time consuming methods presently employed, such as suspending reinforcing rods by wires, and spacing forms through the employment of spacing bars. The unit bracket of the present invention will retain the forms spaced a predetermined distance, hold the reinforcing rods in proper position during pouring of concrete and positively anchor the floor joists and roof rafters to the concrete tie beams.

Other objects of the invention will beapparent from the following description of the present preferred forms of the invention, wherein:

Figure 1 is a perspective view of an anchor bracket constructed in accordance with the present invention; and

Figure 2 is a side elevational view of a pair of the brackets illustrating their application as applied to a roof rafter, floor joist and building wall.

In order to illustrate the application of this invention, I have in Figure 2 of the drawings shown a portion of a building including a roof rafter 3, oor Joist 3, a concrete tie beam 4, and a cement block wall 5. The tie beams are circumscribed by forms Ii in a manner Well known in the art. In addition, in accordance with standard building construction, I have interposed a plate I between the roof rafter and the upper terminal of the top concrete tie beam 4.

The bracket of the present invention comprises a flat plate preferably made of sheet metal, the body B of which is of rectangular or closed U-shape and comprising a pair of parallel sides 9. Each of the sides is provided near its terminal with a reinforcing rod receiving groove or recess I0. These grooves are adapted to receive reinforcing rods II, as illustrated in Figure 2. The top of the body is closed by a bar I2 formed integral with the sides 9 and extended beyond the marginal edges thereof to provide spacer arms I3 adapted to abut the inner walls of the forms 6, as also shown in Figure 2. Issuing from the upper margin of the spacer bar I3 are a pair of extensions or legs I4 and I5, the free ends of which are offset in the same ticularly directed to the fact that the root of the leg I4 is uniplanar with the longitudinal axis of direction. Attention is par.

'bracket is used in reverse one of the sides of the body 8. Conversely, the root of the leg I5 is completely offset from the longitudinal axis of the opposite side of the body 8. The legs I4 and I5 as well as the offset extensions thereof, I4 and I5', are provided with apertures I6 for use in anchoring the bracket to rafters, joists and form braces.

It is to be understood that the device of this invention serves:

(a) As an anchor for roof rafters as required by the building codes;

(b) As an anchor for floor joists by reversing the bracket as shown near the bottom of Figure 2, as also required by the building code;

(c) As a bracket to support reinforcing rods in proper position in concrete tie beams, after the fashion illustrated in Figure 2 as also required by the building codes.

In use of this bracket for anchoring a rafter to the tie beam, the anchor is positioned in the form as shown at the top of Figure 2 and the reinforcing rods Il engaged in the grooves I0. The arms I3 automatically space the sides of the form 6. Consequently, the concrete of the tie beam is formed of a predetermined width reinforced by the rods I'I supported in the desired loci. The offset end I5 of the leg I5 is anchored to the rafter 3 in an obvious manner. When the bracket is used to anchor a rafter to a concrete tie beam, the offset end I4' of the leg Ill may be bent over flush with the top of the tie beam. When, however, the bracket is used to anchor the floor joist 3 to the concrete tie beam, the offset end I4 of the leg I4 is used as shown at the bottom of Figure 2 of the drawing. The offset end I4 is adapted to engage a portion of the oor jOist which overhangs the top of the lower concrete tie beam 4. When the bracket is used to anchor a joist to the concrete tie beam, the offset end I5 of the leg I5 is engaged with the cement block wall 5. The body 8 of the bracket is embedded in the concrete tie beam just the same as when the for engaging the roof rafter with an upper tie beam.

Although I have herein described a preferred form of the invention, I am of course aware that various changes may be made therein within the scope of the appended claims. It is, however, of importance in the present invention that a bracket be provided which is adapted for use in securing the rafters of a building to the tie beams and also by mere reversal used for securing floor joists to the tie beams. The manner of securing the bracket to the rafters and joists may vary, but I have found that satisfactory anchorage is ob- 3 tained by driving spikes through the rafters or joist and the openings i6 of the bracket. Also, by mounting the brackets in the concrete at right angles to the reinforcing rods, shrinkage and temperature reinforcement is provided for.

What I claim is:

1. An anchor bracket for use in the building industry comprising a iiat substantially U-shaped plate the legs of which at the open end of the U are offset in the same general direction and within the plane of the plate, said legs being also provided inwardly from the open end of the U with notched edges for engagement with concrete reinforcing rods, and projections extending laterally from the legs intermediate the ends thereof and arranged in alignment to provide a form spacer.

2. An anchor bracket for buildings comprising a body one end of which is formed to provide a plate-like portion for engagement in a tie beam, the opposite end formed to provide a U-shaped portion presenting legs one of which is adapted for engagement with the part of the building which is to be anchored to the 'tie beam, and parts of the body extending laterally from the platelike end thereof to provide spacers, the free ends of said legs being offset.

3. A bracket .for use in anchoring roof rafters and floor joists to lconcrete tie beams, including a rectangular body adapted 'to be embedded in the tie beam and provided withmarginal recesses for the .reception of yreinforcing rods, partsfof the opposite sides ofthe body beingextended to provide spacer arms, further parts .issuing from one end of the body to provide legs,.one of which is adapted for engagement with a rafter, the other of said legs being adapted for engagement with a joist.

4. As a new article of 'manufactura an anchor ments extending from the top thereof for attach ment respectively to roof rafters and floor joists, and a concrete pouring form spacer bar at the junction of the plate-like member and the anchor elements.

5. Means for anchoring a roof rafter and iioor joist to a concrete tie beam, comprising a plate embodying a pair of parallel sides, the outer margin .of keach of which sides provided with reinforcing `rodreceiving recesses, the plate also including a bar integral with said parallel sides at one end, the terminals of the bar extending beyond said outer margins of the parallel sides to provide spacer arms for the form of a concrete tie beam, the ,plate further including an extension issuing from said bar for engagement with a roof rafter or ,door juist, said extension being olset from thelong axis of the parallel sides.

6. An anchor bracketfor buildings comprising a bracket body one end of which is adapted for mounting in a concretetie beam form, an intermediate part ofthe body extending beyond the sides of said bracket body end for engagement with opposite walls of the concrete form to retain the walls 1n predetermined spaced relation, the

chored to the tie beam.
