Abstract

(57) [Summary] [Problem] To enable assembling a base reinforcement and a cloth reinforcement easily on site. SOLUTION: A base muscle A is composed of left and right muscles 1 and a horizontal muscle 2 connecting them in parallel.
It is composed of three longitudinal streaks 3 in the middle and lower stages, and a vertical streak 4 connecting these in parallel. The assembly metal fitting C is obtained by bending a single steel rod, and includes an inverted U-shaped part 5, a holding part 6, and a leg 7. The inverted U-shaped portion 5 has a shape such that the lower two longitudinal reinforcing bars 3 of the reinforcing bar B can pass therethrough. And a hook 8 that engages with the left and right muscles 1 of the base muscle A from the outside. When assembling, first, the inverted U-shaped part 5
The hook 8 of the holding portion 6 is hooked on the left and right muscles 1 of the base muscle A so that the inverted U-shaped portion 5 is widened. Since the holding portion 6 is pulled inward by the elastic force of the inverted U-shaped portion 5, the hook 8 does not come off from the left and right muscles 1. In this way, when the base stirrups A and the cloth stirrups B are joined by using the assembling bracket C at regular intervals, the cloth stirrups B are held vertically on the center line of the base streaks A.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a reinforcing metal fitting for building a concrete foundation for a house or the like.

[0002]

[Prior art]

 Reinforcing bars for residential concrete foundations have an inverted T-shaped cross section, and a part corresponding to a T-shaped horizontal bar (base bar) and a portion corresponding to a vertical bar (cloth bar) are separately manufactured at a factory. , To be assembled on site. Conventionally, in this assembly, an L-shaped reinforcing bar was applied between a base bar and a fabric bar, and was tied with an iron wire.

[0003]

[Problems to be solved by the invention]

 However, there is a problem that such a binding operation using an iron wire requires a lot of man-hours and requires a certain amount of heat kneading. An object of the present invention is to provide an assembling metal fitting used for joining a base and a reinforcing bar in order to solve such a problem.

[0004]

[Means for Solving the Problems]

 The rebar assembly bracket of this invention crosses a base bar consisting of left and right bars connected in parallel with each other by horizontal bars and a cloth bar consisting of a plurality of vertical bars connected in parallel with each other by vertical bars. An inverted U-shape for connecting the bars in an inverted U-shape, through which at least the two lower longitudinal bars of the reinforcing bar pass. A clamping portion extending outward from each end of the inverted U-shaped portion and having a hook at its tip for hooking the left and right muscles of the base streak so as to widen the inverted U-shaped portion; It consists of legs that extend further down from the clamp.

At the time of assembling, the inverted U-shaped part of this assembling bracket is hung on the two lower longitudinal bars of the reinforcing bar, and the hook of the holding part is connected to the left and right muscles of the base muscle so that the inverted U-shaped part is widened. Hang on. Since the inverted U-shaped portion is elastic and tends to return to its original shape, the holding portion holds the left and right streaks from the outside and does not come off. The metal fittings are used at appropriate intervals in the longitudinal direction of the reinforcing bar to hold the reinforcing bar vertically above the base bar.

[0006] On the other hand, the legs hold the base streaks higher than the grite stone surface, and when the concrete is struck, the base streaks are securely wrapped in the concrete.

[0007]

[Embodiment of the invention]

 In FIGS. 1 and 2, reference numeral A denotes a base reinforcement, reference numeral B denotes a cloth reinforcement, and reference numeral C denotes an assembly fitting of the present invention. The base muscle A is composed of left and right muscles 1 and a horizontal muscle 2 connecting them in parallel, and a cloth muscle B is connected to the three longitudinal muscles 3 of upper, middle and lower rows and connecting them in parallel. Vertical streaks 4.

The metal fitting C is formed by bending a single steel bar, and includes an inverted U-shaped portion 5, a holding portion 6, and a leg 7. The inverted U-shaped portion 5 has such a shape that the lower two longitudinal reinforcing bars 3 of the reinforcing bar B can pass through the inside thereof, and the holding portion 6 is separated from each end of the inverted U-shaped portion 5. The hook 8 extends from the outside and engages the left and right muscles 1 of the base muscle A from the outside.

In use, first, the inverted U-shaped portion 5 is hung on the two lower longitudinal bars 3 of the cloth reinforcement B, and the hook 8 of the holding portion 6 is connected to the base 8 so that the inverted U-shaped portion 5 is widened. Hang on the left and right muscle 1 of muscle A. Since the holding portion 6 is pulled inward by the elastic force of the inverted U-shaped portion 5, the hook 8 does not come off from the left and right muscles 1. In this manner, when the base stirrups A and the cloth stirrups B are joined by using the assembling brackets C at regular intervals, the stirrups B are vertically held on the center line of the base stirrups A.

On the other hand, the leg 7 lifts the base bar A from the surface of the grindstone 9, and as shown in FIG. 2, when the concrete foundation 10 is completed, the base bar A is positioned at the center of the thickness of the base concrete 10. So that it comes to

In the above-described embodiment, the entire metal assembly is formed by one bent iron bar. However, as shown in FIG. 3, the leg 17 may be formed of plastic and put on the main body. As shown in FIG. 4, the hook 28 together with the leg 27 can also be made of plastic.

[0012]

[Effect of the invention]

 As described above, the reinforcing bar assembly of the present invention has an inverted U-shaped portion through which the reinforcing bar passes, and the reinforcing bar is sandwiched by the elasticity of the inverted U-shaped portion. Is held vertically so that bundling with iron wire is not required, and even non-skilled workers can perform quick and reliable work. In addition, since the legs lift the base muscle from the surface of the grime stone, there is an effect that it is not necessary to use a separate spacer.
