PATENTED DEVICES COMPANY, OF PORTLAND, MAINE, A CORPORATION OF MAINE.
REINFORCED CONCRETE CONSTRUCTION.
Specification of Letters ratentr Patented Feb. 22, 1916.
application filed November 16, 1911. Serial No. 660,601.
. is a specification.
In constructing reinforced-concrete floors and the like, the reinforcing bars or members should be secured at the desired distances apart and in the required horizontal plane before the concrete is poured.
The present invention relates to improved means for thus securing and positioning the reinforcing members.
In the'accompanying drawings, Figure 1 is a; fragmenta-l top plan view showing the decking or form-work upon which the concrete is to be poured,'and representing several reinforcing bars as secured and spaced by means embodying my invention. Fig. 2 1s a fragmental sectlonal vlew, lllustrating the securing and spacing means in side elevation.- Fig. 3 represents the securing and spacing means in edge elevation and in partial section. Figs. 4 and 5 are views similar to .Figs. 2 and 3, respectively, but showing an alternative construction.
The decking is indicated at A and the reinforcing barsat' B. These bars are supported at the desired distance from the lower side of the floor slab to be constructed,
and at the desired distance apart, by means including a plurality ofstays or longitudinal members 1 each consisting of a metal strip, such as a strip of hoop iron,- said strip being bent at intervals to form chairs 2 to support the bars B. These chairsmay be of any suitable shape or form. In Figs. 1, 2 and 3 each chair consists of a V-shape leg .or gage 3 and .two downwardly extending portions t at opposite sides of the leg 3, the portions of the longitudinal member 1 between the chairs being arranged to lie sub stantlally flat upon the decking and being integrally connected with the lower ends of the side portions 4.
The means for securing the bars B to the chairs may be of any suitable character. The preferred construction consists in weld- .ing or otherwise afiixing to each chair a strip 5 of sheet metal or other suitable material, the strip being secured at its midportiouto the chair, and the ends of the strlp being bendable to embrace the bar.
The bar-engaging or embracing means is welded at a" and therefore bridges or conpunching bar-engaging arms therefrom;
thus the provision of separately-formed bargaging means welded or otherwise secured in place not only obviates impairment of the strength of the chair, but positively stiffens and reinforces it.
The device herein shown comprises a connected series of chairs. Figs. 1, 2 and 3 show the chairs as formed out of an integral strip of metal, but they may be otherwise connected. In Figs. 4t and 5 the chairs are formed separately from, and welded or otherwise suitably attached to the longitudinal member 1 at 3/. An advantage of the last mentioned construction is that the chairs may be conveniently spaced at any desired distance apart, and at regular or irregular distances. A further advantage is that the portion of the longitudinal member 1 below the chair ties the parts of the chair together spreading of such side portions is claimed generically in my co -pending application Serial No. 658,683, filed November 6, 1911.
I claim as myinvention:
1. A gage member for reinforced-concrete construction consisting of a metallic band having bar-supporting chairs attached to the band at intervals, each chair comprising a leg or gage extending downwardly to the plane of'the band and adapted to space a reinforcing bar from a form-work and two side portions at opposite sidesof the gage, extending downwardly from the top of the gage to the plane of the.band. v
2. A gage member for reinforcedrconcrete construction consisting of a metallic band having bar-supporting chairs attached to the band at intervals, each chair comprising a leg or gage extendlng downwardly tothe plane of the band and adapted to space a reinforcing bar from .a form-work, and two side portions at opposite sides of the gage, extending downwardly from the top of the gage to the plane of the band, and bar-engaging means attached to the upper part of the chair and adapted to strengthen the chair and prevent its sides from spreading apart.
' 3. A gage member for reinforced concrete construction,-consisting of a. metallic band forming a longitudinal connecting member and a series of reinforcing-bar-supporting chairs each connected tosaid member, each of said chairs consistingof a folded legor uppe portion of the gage and-being connecte to said longitudinal member.
In. testimony whereof I afiix my signature in the presence of two Witnesses.
