Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for arranging reinforcing bars for reinforced concrete walls and the like.

Prior Art Conventionally, reinforcing bars in reinforced concrete walls or wall columns were arranged vertically and horizontally on site, and the intersections were connected with binding wires. Problems with such a method are as follows.

The reinforcing bars are tied together one by one manually on site, which is extremely time-consuming.

Binding wire alone provides weak restraint, tends to disturb the reinforcement arrangement, and tends to cause variations in the precision of the reinforcement arrangement.

Purpose of the Invention This invention was made to improve the above-mentioned drawbacks, and its purpose is to provide a method for arranging reinforcing bars for reinforced concrete walls, etc., which can be arranged very simply, reliably, and more accurately. do.

Structure of the Invention The method of arranging reinforcing bars for reinforced concrete walls, etc. according to the present invention is to arrange a plurality of main reinforcing bars vertically at the ends or corners of a reinforced concrete wall, etc., and to bend the main reins into a rectangular shape around the outer periphery of the main reinforcing bars. Arrange multiple reinforcements to form a column, weld vertical and horizontal reinforcements in advance to create a stirrup network, and extend and bend the reinforcing bars on one side of the stirrup network.
Form a hook bent at 45 degrees, extend and bend the reinforcing bars on the other side to form a hook bent at 90 degrees, and then attach a hook bent at 45 degrees to the main reinforcement of one column between the columns. At the same time, the tie bar network is rotated around the main bar, and a hook bent at 90 degrees is locked to the main bar of the other column, and the tie bar network, which is made by welding reinforcing bars vertically and horizontally between the columns, is parallelized. The above object is achieved by forming a wall section by standing upright on the wall.

Embodiments Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

Figures 1 and 2 show the case of constructing a concrete wall with a straight cross section. A plurality of main reinforcements 1 are arranged vertically at both ends, and horizontal reinforcements 2 are placed around the outer periphery of the main reinforcements 1. The reinforcement is placed at appropriate intervals and bent into a rectangular shape. As described above, the column A is formed by the main reinforcement 1 and the horizontal reinforcement 2.

Between the column parts A, a tie reinforcement network 3 is installed parallel to each other. The tie reinforcement network 3 is made up of longitudinal reinforcements 4 and transverse reinforcements 5 arranged vertically and horizontally in advance by welding in a factory, and is formed to a predetermined size on site. Strap muscle network 3
Then, the reinforcing bars on one side are extended and bent to form a hook bent at 45 degrees, and the reinforcing bars on the other side are extended and bent to form a hook bent at 90 degrees. This reinforcement network 3 is brought to the end opposite to the opposite end of the column A, and hooks 6 are locked to the main reinforcement 1, and stretched in parallel to the wall B.
is formed.

When tensioning this tie bar network 3, the 45 degree hook 6 is locked to one of the main bars 1, the tie bar network 3 is rotated around the main bar 1, and the 90 degree hook 6 at the other end is attached from the side. It is locked to the other main reinforcement 1 so as to be slid.

The embodiment shown in Figures 3 and 4 shows the case of constructing a concrete wall with an L-shaped cross section.
By the above-mentioned operations, column parts A are formed at the ends and corners, and the tie reinforcement net 3 is stretched.

The embodiment shown in FIGS. 5 and 6 shows the case of constructing a concrete wall with a T-shaped cross section.
By the above operations, column A is formed at the end, a plurality of main reinforcements 1 are arranged at the intersection, and a tie bar network 3 is stretched between the main reinforcements 1 such as column A. .

Effects of the Invention The present invention has the above-described configuration, and since the straps assembled by welding in a factory are stretched on-site, the work can be carried out extremely easily. In addition, the reinforcement of the tie reinforcement network is not disturbed and can be placed accurately.

Claims (1)

[Scope of Claims] 1 A plurality of main reinforcements are arranged vertically at the end or corner of a reinforced concrete wall, etc., and a plurality of horizontal reinforcements are arranged around the outer circumference of the main reinforcements bent in a rectangular shape to form a column. The vertical and horizontal reinforcements are welded in advance to create a stirrup network, the reinforcing bars on one side of the stirrup network are extended and bent to form a hook bent at 45 degrees, and the reinforcing bars on the other side are extended and bent. to form a hook bent at 90 degrees, and lock the hook bent at 45 degrees to the main reinforcement of one of the columns between the columns, and rotate the tie reinforcement network around the main reinforcement to form a hook on the other column. Rebar arrangement for reinforced concrete walls, etc., where hooks bent 90 degrees are locked to the main reinforcement of the section, and a grid of reinforcing bars is erected in parallel between the column sections by welding vertically and horizontally to form a wall section.
