DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of laying a wall reinforcement of a thick reinforced concrete wall such as a load-bearing wall or an underground continuous wall on the ground.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional reinforcing bar for a thick reinforced concrete wall is a shear reinforcing bar 3 for restraining a lattice member of a horizontal bar 1 and a vertical bar 2 in a thickness direction of the wall. A hook 3a having bent left and right ends is provided.
Each book is formed as a short unit.

[0003]

As described above, since the shear reinforcing bars 3 are formed one by one as a short piece, the number thereof is increased, the number of assembling work steps is increased, and a large number of labor is required.

[0004] When the wall reinforcement is laid on the floor on the floor, it is not possible to arrange the reinforcement with only the shear reinforcement 3, so a jig called “equine” is required.

Further, as described above, since the shear reinforcing bar 3 is a single piece, a large number of binding points are required, and depending on the type of working jig, it is necessary to bind the jig and the reinforcing bar.
The number of binding places is very large.

SUMMARY OF THE INVENTION An object of the present invention is to solve the disadvantages of the prior art, to improve workability in assembling and to reduce the number of binding points, so that the number of man-made objects can be greatly reduced and a jig is unnecessary. It is to provide a method.

[0007]

According to the present invention, in order to attain the above object, a lower horizontal streak and an upper vertical streak are arranged at a pitch, and a lightning-type shear reinforcement is laid thereon. The lightning-type shear reinforcement is laid out as specified, and the lower longitudinal muscle is arranged so as to pass through the valley tip of the lightning-type shear reinforcement, and the lightning-type shear reinforcement is raised to raise the lightning-type shear reinforcement. Bound the tip and the lower longitudinal streak, and then lift the upper longitudinal streak and bind it to the tip of the lightning-type shear reinforcement, and also connect the lower horizontal streak and the lower longitudinal streak to The gist of the present invention is to bind at the intersection, arrange the upper horizontal streaks on the upper vertical streak, and bind the intersection.

[0008]

According to the present invention, the lightning-type shear reinforcement is not a single product but a continuous one, so that the number of binding points and the number of man-hours required for processing are reduced.

Further, the horse required conventionally is not required, and the number of binding parts is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 6 are perspective views showing each step of the method for laying a wall reinforcement according to the present invention.

First, as shown in FIG.
The arrangement position of the horizontal streaks and the arrangement position of the lightning-type shear reinforcement 4 to be described later are marked out, and the lower horizontal streak 1a located on the lower side in the ground state and the upper vertical streak 2b located above the lower streak are referred to as black. Arrange according to the pitch. At that time, the upper vertical streak 2b is placed on the lower horizontal streak 1a so as to be orthogonal to the lower horizontal streak 1a. In this state, no binding is performed.

Next, as shown in FIG. 2, a lightning-type shear reinforcement 4 continuously formed in a corrugated or zigzag shape as a width stop is further laid thereon at a predetermined position (predetermined allocation). Line up. No binding is performed in this state.

As shown in FIG. 3, a lower vertical bar 2a is placed on the lightning-type shear reinforcement 4 so as to pass through the tip of a valley 4a of the lightning-type shear reinforcement 4, and is arranged.

As shown in FIG. 4, this lightning-type shear reinforcement 4
Is caused and the tip of the valley 4a and the lower longitudinal streak 2a are bound by a binding line, and then the upper longitudinal streak 2b is set in the crest 4b of the lightning type shear reinforcement 4 as shown by an arrow. Lift up the mountain 4
b.

As shown in FIG. 5, the lower horizontal streak 1a and the lower vertical streak 2a are bound at the intersection thereof to maintain three-dimensionality.

Further, the upper horizontal streaks 1b are arranged so as to be orthogonal to the upper vertical streaks 2b, and their intersections are bound.

[0017]

As described above, the prefabricated wall rebar and the method of assembling the same according to the present invention have good workability in assembling, and reduce the number of tied parts, so that the number of man-made can be greatly reduced. That is all.
