3 Claims.

This invention relates to the art of concrete reenforcing means, and has reference more particularly to an improved clip for reenforcing a concrete beam or column having an embedded steel structural member such as an I-beam. A concrete reenforcing soflit clip of the same general type as that of the present invention is disclosed in my former Patent No. 1,801,879, granted April 21, 1931, and the main object of this invention is' to provide an improved reenforcing clip that will combine all the structural and functional advantages of the clip of my aforesaid patent with substantially increased structural simplicity, greater reenforcing capacity, substantially decreased cost of manufacture, and greater ease of application.

An illustrative embodiment of the invention is presented in the accompanying drawing, where- Fig. 1 is a cross sectional view of a concrete beam mold or form, a structural steel member, and my improved sofiit clip applied to the latter.

Fig. 2 is a perspective View of the steel I-beam and soflit clip shown in Fig. 1.

Fig. 3 is a perspective view of the improved clip as it appears before application to the I-beam.

Referring to the drawing, H! designates a wooden form or mold in which the concrete beam is cast, and I l designates a structural member, herein shown as an I-beam, around which the concrete is cast.

l2 designates as an entirety my improved individual clip which comprises a pair of parallel upright members [3 that span the top and bottom flanges of the I-beam l l and have their upper end portions I2 bent inwardly to overhang the top flange of the I-beam and thus suspend the clip from the latter. l4 designates a transverse limb which underlies and is spaced from the bottom flange of the I-beam I l and extends some distance beyond the edges of said flange into the soilit region of the beam, and I5 designates each of a pair of limbs that connect the lower ends of the upper limbs l3 with the ends of the transverse limb l4, the limbs l5 being preferably inclined as shown. Connecting the lower ends of the upright limbs l3 and underlying the bottom flange of the I-beam in contact therewith is atie wire I 6.

The facility and ease of mounting the clips on the I-beam are obvious. The clip, in the form shown in Fig. 2, is entered on the beam from beneath the latter and raised until the tie rod It comes into contact with the bottom of the beam, and then the portions of the vertical limbs l3 projecting above the top of the beam are flattened down on the latter forming the suspension hooks l2. The described construction also facilitates the spacing of the clips along the beam by merely pushing or drawing each clip sidewise to its correct position in relation to adjacent clips. And the tie rod l 6, through contact with the bottom of the beam, insures the correct position in the molded beam of the underlying limbs M and i5 of the clip, which, by building ordinances in some localities, are required to be not less than a certain minimum distance from the outer surface of the molded beam.

The vertical limbs l3, which extend the full height of the I-beam, also reenforce the side regions of the molded beam and tie said side regions to the bottom or soflit region.

Furthermore, all the parts of the clip are in a single vertical plane, so that, when the concrete or cement is poured into the mold and then tamped or puddled the clip is not liable to displacement from correct position by blows on laterally projecting parts thereof.

I claim:

1. A concrete reenforcing clip of the class described, comprising an individual wire structure adapted to be mounted on an embedded structural member and comprising a pair of upright limbs spanning the vertical height of said structural member and at their upper ends suspended from said member, a straight transverse limb underlying and spaced from the bottom of said structural member and projecting beyond the sides of the latter, and limbs connecting the ends of said transverse limb with the lower ends of said up-- right limbs.

2. A concrete reenforcing clip of the class described, comprising an individual wire structure adapted to be mounted on an embedded structural member and comprising a pair of upright limbs spanning the vertical height of said struc--, tural member and at their upper ends suspended from said member, a transverse limb underlying and spaced from the bottom of said structural member and of greater length than the width of said structural member, limbs connecting the ends of said transverse limb with the lower ends of said upright limbs, and a tie member connecting the lower ends of said upright limbs beneath and in contact with the bottom of said structural member.

3. A concrete reenforcing clip of the class described, comprising an individual wire structure adapted to be mounted on an embedded I-beam, and comprising a pair of parallel upright limbs spanning the topand bottom flanges of the beam and at their upper ends bent inwardly to overlie the top flange, a transverse limb underlying and spaced from the 1 bottom flange of said beam parallel with said bottom flange and projecting beyond the latter, inclined limbs connecting the ends of said transverse limb with the lower ends of said upright limbs, and a tie wire connecting the lower ends of said upright limbs beneath and in contact with the bottom flange of said beam.
