Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for attaching mesh panels used on large reinforced concrete beams such as underground beams.

(Conventional technology and problems) Conventionally, it has been extremely difficult to arrange reinforcement on-site for large reinforced concrete beams, so as a solution to this problem,
As shown in Publication No. 58-91272, multiple abdominal muscles and L-shaped muscles (lateral stirrup muscles or tangential muscles)
An assembly method has been devised in which the mesh panels are connected together to form a mesh panel, and the mesh panels are arranged in parallel on the lower stirrup muscle.

However, in implementation, the key point is how quickly and reliably the mesh panel can be attached to the lower stirrup muscle, and the biggest problem has been how to specifically attach the mesh panel.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and provides a method for attaching a mesh panel that can be attached to a lower stirrup bar very quickly, reliably, and easily. The purpose is to provide a method.

Therefore, in the method for attaching a mesh panel according to the present invention, the lower stirrup muscles are arranged at predetermined intervals, the hairpin muscles are arranged on the lower stirrup muscles, and the mesh panel is constructed by connecting a plurality of abdominal muscles and L-shaped muscles. The above object is achieved by placing the lower abdominal muscle on the hairpin muscle, rotating the mesh panel using the lowermost abdominal muscle as a fulcrum, and arranging it in the vertical direction.

(Example) The present invention will be described below based on an example shown in the drawings.

Installation of the outer mesh panel As shown in Fig. 1, the lower stirrup reinforcements 4 are arranged at predetermined intervals on the concrete slab 1 via spacers 2 and sacrificial reinforcements 3, and the main reinforcements 5 and hairpin reinforcements 6 are arranged. Then, the L-shaped part of the outer mesh panel 9 formed by connecting a plurality of abdominal muscles 7 and L-shaped muscles 8 is placed on the sacrificial reinforcement 3 and fixed with binding wires 10.

The main reinforcement 5 at the end is the outer mesh panel 9.
Reinforcement may be placed after installation.

Attaching the inner mesh panel Similar to the outer mesh panel 9, attach multiple abdominal muscles 7.
and the L-shaped reinforcement 8 to form the inner mesh panel 1.
form 1. Then, as shown in FIG. 2, the abdominal muscles 7 at the lowest end of the inner mesh panel 11 are placed on the hairpins 6, and the entire inner mesh panel 11 is rotated using the abdominal muscles 7 as a fulcrum to arrange it in the vertical direction, and then tied. Fix with line 10.

In the embodiment, binding wires 10 are connected to the abdominal muscles 7, the truncatus muscles 6, the L-shaped muscles 8, and the lower stirrup muscles 4, respectively, and the inner mesh panel 11
is installed.

Attaching the Opposite Side Mesh Panel As shown in Figure 3, after installing the other inner mesh panel 11 according to the procedure described in , attach the opposite (outer) mesh panel 9 according to the procedure described in .

In the embodiment, two sets of inner mesh panels 11 are used, but it goes without saying that more sets of inner mesh panels 11 may be used depending on the location.

In addition, the installation of the outer mesh panel 9 is as follows:
It can also be attached in exactly the same way as for the inner mesh panel 11 described above.

(Effects of the Invention) This invention has the above configuration, and when installing it, it is only necessary to place the lowermost abdominal muscle on the hairpin muscle, rotate the entire mesh panel using this abdominal muscle as a fulcrum, and stand it vertically. The mesh panel can be quickly, reliably, and easily attached to a predetermined position by a number of people, and work efficiency is dramatically improved.

Furthermore, since no reinforcement or the like is required for support, less material is required.
