The horizontal muscles 4 are alternately attached to the front and back main muscles, and the muscles are arranged and bound to complete the muscle arrangement work (Fig. E).

FIG. 4 shows a bar arrangement of a floor slab (hereinafter referred to as a slab beam) having the beam function of the embodiment. Beam main bars 8 and 8'are arranged in parallel in the horizontal direction on both upper and lower sides of a slab beam 7 made of thick concrete, and a number of corrugated triangles are formed between the upper and lower main bars 8 and 8 '. Lattice long web streaks 3 are alternately hooked and bent on the upper and lower main streaks 8 and 8'to form a triangular lattice shape, with a predetermined gap between adjacent web streaks 3 and 3, and mutually corrugated. The wavelengths are shifted, and they are arranged along the direction orthogonal to the main bars 8 and 8 '. Then, attach the upper and lower distribution muscles 9 and 9'to the outer side of the upper and lower main reinforcements 8 and 8 ', so that the web reinforcements 3 and
The web muscle 3 and the force distributing muscles 9 and 9'are bound and fixed to the main muscles 8 and 8 '.

The order of reinforcement of this slab beam 7 is shown in FIG.
(B), (c), (d), and (e) are shown in order. The distribution bars 9'are arranged in parallel at intervals of 200 mm (Fig. A), and the upper and lower beam main bars 8, 8'that form a set of two in the direction orthogonal to each other are 400
Bars are arranged in parallel at mm intervals (Fig. b). A triangular lattice-shaped web bar 3 that is bent at a pitch of 200 mm and repeats peaks and valleys is overlaid on the force distribution bar 9'and a set of main bars 8, 8'is arranged at the center of the peak, and at the valley. Binds to muscle muscle 9 '(c
Figure). Subsequently, the upper main bar 8 of the pair of main bars 8, 8'in the center of the mountain section is moved to the mountain section of the web bar 3 and bound. At the same time, a new set of upper and lower beam main reinforcements 8 and 8'is arranged in the valley portion of the web reinforcement 3 (Fig. D).

[Action]

The present invention has the above configuration. This bar arrangement structure alternately hooks triangular lattice-shaped long web bars on the main bars on both the front and back sides of a thick concrete body, and shifts the waveform wavelength between adjacent web bars by 1/2 to form web bars. 2 intersecting alternately
Orientated in the direction, and the main muscles on the front and back are connected in a lattice shape with long web muscles, so only the main muscles are connected, or the main muscles on the front and back are connected by hoop muscles, stirrup muscles, or simply connected in a lattice shape. Compared with, the strength against shear stress is remarkably high, and high rigidity can be imparted to a thick concrete body such as a wall column or a slab beam in combination with the reinforcing effect of the main reinforcement. In addition, the conventional reinforcement that connects the main reinforcement of the wall with the horizontal reinforcement and the hoop reinforcement also has a lot of waste of reinforcement, but this reinforcement has a triangular lattice-shaped long web reinforcement attached to the main reinforcement. Since rebars can be arranged, there is no waste of rebar and workability is excellent.

In addition, the method of arranging thick-walled concrete bodies that make up the wall pillars is because it is possible to lay the web by simply hooking the web bar to the bar and stacking it, and then pulling it up to the specified height of the main bar and fixing it. Excellent workability.
