Application filed December-26. 1917. .Seria1No. 208,966.

To all whom it may concern:

Be it known that I, HENRY H. LAMPERT, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain I new and useful Improvements in Reinforciiig Systems for Concrete, of which the following is a specification. I

The main objects of this invention are to provide an improved reinforcing system for concrete embodying the use of a plurality of'rods or bars spaced apart in rows; to provide improved means for spacing said rods;

to provide improved'means for supporting said spacing means rigidly in place; to provide improved means for locking said supporting means and said spacing means together; to provide improved meansfor securing the reinforcing rods to said spacing means; and to provide a system of reinforcing of this kind particularly adapted for use inkthe formation of beams, pillars, and the An illustrative embodiment of this inven tion is shown in the accompanying drawings, inwhich- I forcing arranged thereln.

Fig.2 is a similar view showing a slight modification of the reinforcing system as rega'dsfthe supporting of the first row of ro s.

Fig. 3 is a transverse sectional detail taken on the line 33 of Fig. 1.

Fig. 4 is a similar view taken on the line 4:4: of Fig. 2.

Fig. 5 is a perspective view of one of the supporting members which supports the second spacing member above the first spacing member in the system shown in Fig.1. 1

Fig. 6 is a similar view of the supporting members which support-the first or lowermost spacing member in the system shown in Fig. 2.

Fig. 7 is 'a perspective view of one of the supporting members used for supporting the I spacing members on edge.

This improved system of reinforcing involves the use of a plurality of spacing members 1 supported 'in spaced relation one above another by means of supporting members 3 so as to support rows of reinforclng rods orbars 2 thereon. Fastening means and locking means are provlded for securing the rods inplaceon the spacing members and for locking the spacing members and the supporting members together The spacing members 1 are herein shown in the form of fiat, comparatively thin, metal strips which vary in width, depending upon the distance the rods "are to be spaced apart. These strips are used either fiat or on edge. When used edgewise, notches are formed in the u per edges in which the bars 2 are to be seated. The spacing of the notches along the strips serves to properly space the bars in their respective rows.

spacing strips 1 are held in spaced relation are in the form of chairs 3 each comprising.

essentially a pair of depending

legs

4 and 5 connected together at their upper ends and spaced apart at'their lower ends. The exact form of these chairs depends somewhat upon the place in the system in which they The supporting members by which the I are to be used and. the arrangement of'the spacing members which they are to support. I When the first or lowermost spacing strip is supported with its face substantially par- Figure 1 is a cross section of a mold for a" beam, showing the improved system of rein-- allel to the adjacent Wall-of the mold, and the other strips above are disposed edge-- wise to said first strip,-the supporting members for said firststrlp are preferably of the form 7 shown in connection with said first strip in Fig. 1, and the supporting members for the strip next above are preferably of the form shown in Fig. 5 When the first or lowermost spacing strip is supported on edge as regards the adjacent wall of the mold, the supporting members the'refor'are nection at their upper ends provides a transverse seat part upon which thespacin'g memher 1 rests. The other forms of supporting members 3- herein shown are all of substantially an inverted V-s'hape construction.

In the form shown in Fig. 5, a notch or recess 6 extends inwardly from the upper end into which a spacing strip 1 is received. Lugs 7 are formed on the ends of the

legs

4 and 5 which are adapted to extend through as shown in Figs. '2 and 4. In the. form shown in Fig.7, notches 6 extend inwardly from the upper end and other notches .9 extend upwardly from the'bottoms of the

legs

4 and 5. The notches 9 are adapted to permit this supporting member 3 to-straddle a spacing member 1 above which it is to support another spacing member, and said other spacing member is received in the notches 6.

Fastening means may be provided, if desired, for securing the reinforcingv rods 2 to the respective spacing members 1, which may be accomplished in various ways, as illustrated in the drawings. When the lowermost spacing member lis disposed with the face substantially parallel with the adjacent wall of the mold, the rods maybe held in place by means of fingers 10 bent around the rOdS. These fingers may be formed either on the supporting member3', which is the form herein shown and which is more fully described and claimed in my copending application Serial No. 202,i39,'filed November 17, 1917, or they may beintegrally formed on the spacing member itself, as shown and described in my copending application, Serial No. 207 ,114, filed December-14:, 1917. For the bars supported on the uppermost or outermost spacing member, the locking is conveniently accomplished by having pieces of wire 11 secured in apertures '12formed in the spacing member 1 adjacent to the points at which the bars are to be supported, which wires'are adapted to be twisted around the bars as shown in the figures. Inthe modifications herein shown, the intermediate rows of bars are retained in place through their being supported in the notches formed in the edges of the spacing members 1 and having the spacing members above placed in such close proximity to those below that the space between the opposed edges of the spacing members is too narrow to permit displacement of the rods. The retention of the mtermediate rods in theirrespective places may be enhanced by placing the chairs or supporting members 3 astride the rods as indicated in some parts of the figures.

The locking means for securing the spacing members 1 and the supporting members 3 rigidly together are most conveniently provided by having shoulders or lugs 13 upset from the plane of the strips or spacing members 1 and located so that when the strips rest in the bottoms of the notches 6, said lugs or shoulders engage the under side of the upper end of the chairs.

In order to facilitate-the flow of concrete in and'around all parts of the supporting and spacing means for the rods, openings 1 1 are formed at points along the spacing members 1. v

It will be understood that numerous de tails of the constructions shown may be altered or omitted and still other modifica- 1 tions produced without" departing from the members supporting said spacing members one upon and above the other, and means for securing said spacing members and said'supporting members together.
