[Industrial applications]

 The present invention relates to the assembly of a reinforcing bar used in a reinforcing bar concrete structure, and more particularly to the positioning of a reinforcing bar for a wall and a slab reinforcing bar, and an assembly fitting.

[Prior art]

 Conventionally, most of the rebar assembly is done by manual work that relies on the skill of the operator, the dimensioning worker is done by a folding scale, tape measure, and chalk, and the rebar is assembled by a binding line. It was done by binding the parts. The situation is shown in FIG. 13, FIG. 14, FIG. 15 and FIG. 16, taking slab muscle and wall muscle as examples.

[0002] In part, aiming to rationalize these operations, U-position 61-124-254 E04C 5/20 is used for positioning the reinforcing bar of the slab muscle.

[0003]

[Problems to be solved by the device]

 Among the conventional techniques described above, the former has a problem that it requires skill and time, and the latter has a problem that positioning is possible but reliable assembly is not possible.

Further, in the latter, there is a problem that the work of attaching the reinforcing bar to the device is troublesome and time consuming, which does not lead to the improvement of the work efficiency, and it is too expensive for the cost of the device itself. There was a problem that it did not lead to cost savings because it passed.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to firmly assemble a reinforcing bar without requiring skill by a simple operation. It is an object of the present invention to provide an assembly / positioning metal fitting that can be performed accurately, quickly, and inexpensively.

[0006]

[Means for solving the problem]

 In order to achieve the above object, the wall vertical bar, the slab lower bar positioning, and the assembly metal fitting (hereinafter referred to as the metal fitting 1) in the present invention have a groove shape, and the flange surface thereof has a reinforcing bar positioning assembly at a predetermined interval. It has a semicircular notch and a square notch for attachment. The square notch is used for assembling the upper slab and assembling the positioning metal fitting (hereinafter, metal fitting 2). Also, the web surface has bolt holes for assembling horizontal wall reinforcement, upper slab reinforcement, and assembly with a positioning tool.

The metal fitting 2 has a groove-like shape, and has an inverted boots-shaped notch for mounting the reinforcing bar positioning assembly and a square notch for assembling with the metal fitting 1 at predetermined intervals on the flange surface thereof. The surface has a bolt hole for mounting with the metal fitting 1.

The present invention consists of the basic structure of the above two members and a wing nut-attached bolt that is used for holding both the vertical slab and vertical and horizontal slabs of the slab that are assembled with each other.

[0009]

[Action]

 First, the operation will be described by taking the case of using the present invention for the arrangement of slab muscles as an example. FIG. 4 shows the situation in which the spacer is placed on the slab formwork (9) and the metal fitting 1 is placed on the spacer. Next, the metal fitting 2 is placed on the metal fitting 1, with the flange tip of the metal fitting 2 entering the notch formed in the flange of the metal fitting 1. Figure 5 shows the situation. As shown in FIG. 2, the metal fitting 2 (2) is provided with a notch (6) for arranging the upper bar of the inverted boots type on the web portion. After the metal fitting 1 and the metal fitting 2 are temporarily fixed, the lower end bar (12) of the main bar is first arranged in the notch part (3) of the metal part 1, and the lower end bar of the distribution force bar (6) is arranged in the notch part (6) of the metal part 2. 13) is provided. The slab streaks are now arranged in a cross pattern at specified intervals. FIG. 6 shows the situation. Next, securely fix the bottom end bar of the slab and the bottom end bar of the force distribution bar of the slab, and tighten the brackets 1 and 2 with the attached wing nut bolts (8) to prevent them from moving. When the two metal fittings are tightened, the slab muscle is pressed by the metal fitting 1.2, the lower end muscle of the main bar is gripped by the notch (3) of the metal fitting 1, and the lower end muscle of the distribution muscle is the notch (6) of the metal fitting 2. ), It is fixed so that it does not move back and forth, and the slab reinforcement work is completed. FIG. 7 shows the situation.

Next, the operation will be described by taking as an example the case where the present invention is used for arranging wall muscles. Attach the metal fitting 1 (1) to the upper part and the foot of the vertical wall of the wall (14) by using the round separator (15). The metal fitting 1 is provided with a notch (3) for positioning and arranging the wall vertical bars according to the pitch of the wall vertical bars. Next, the metal fitting 2 (2) is attached along the metal fitting 1, with the flange tip of the metal fitting 2 entering the notch (4) provided in the flange of the metal fitting 1. FIG. 8 shows the situation. After temporarily fixing the metal fitting 1 and the metal fitting 2 with the wing nut-attached bolt (8), first arrange the vertical line in the notch of the metal fitting 1. FIG. 9 shows the situation. Next, the horizontal bar (16) is arranged in the notch (6) of the metal fitting 2, but the metal fitting 2 has a notch (6) for arranging the upper bar of the inverted boots type on the flange as shown in the figure. Since it is provided, it is arranged so that the horizontal streak is inserted in the notch. Thus, the wall streaks are arranged in a cross shape at predetermined intervals. FIG. 10 shows the situation. Next, securely secure the longitudinal and lateral streaks of the wall muscles arranged, and securely tighten the wing nut-attached bolts (8) that were temporarily fixed to prevent them from moving. When the two metal fittings are tightened, the vertical wall and horizontal ribs are pressed by the metal fittings, the vertical ribs are gripped by the notch (4) of the metal fitting 1, and the horizontal ribs are gripped by the notch (6) of the metal fitting 2 and vertically. It is fixed so that it will not move, and the wall rebar work is completed. Figure 10 shows the situation. The above is for single reinforcement, but for double reinforcement, the above operation is repeated. The situation is shown in FIG. 11 (slab) and FIG. 12 (wall).

[Effect of this plan]

 If the slab and wall reinforcements are assembled using this plan, anyone can efficiently assemble the rebar without the need for positioning and tying work that requires skillful rulers.
