Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for arranging reinforcing bars in an underground wall structure.

[0002]

2. Description of the Related Art In general, an underground wall structure is an important structural part and receives a large amount of earth pressure in the surrounding area, so that it has a large amount of reinforcement.

This construction was carried out by a manpower-based scaffolding work because it is difficult to carry in and install large members due to obstacles to the mountain stoppers and the floor height of the underground wall structure is high.

[0004] In this work, as shown in FIG. 10, the reinforcing bar 30 was arranged by a group of 2 to 3 people, and the reinforcing bars 30 were passed over the scaffold 20 one by one.

[0005]

However, since the above-mentioned method of arranging the reinforcing bars is mainly human-powered work, not only the workability is poor, but also the workability under the boarding gantry is very poor. . In addition, as described above, this work was extremely painful for the worker because the person handed over the reinforcing bars one by one over the scaffolding.

The present invention has been made in view of the above problems, and an object thereof is to improve the workability and the workability, and at the same time, to improve the workability and workability of the rebar of the underground outer wall skeleton. It is to provide a arranging method.

[0007]

[Means for Solving the Problems] The method for arranging the reinforcing bars of the underground outer wall structure of the present invention to achieve the above-mentioned object is a method of reinforcing the reinforcing bars of the underground wall structure constructed along the retaining wall of the root cutting part. A method for arranging a bar, wherein a vertical bar unit gripped by a gripping device of a traveling vehicle is built along the mountain retaining wall to arrange vertical bars, and then a horizontal bar unit gripped by a gripping device of the traveling vehicle is The vertical streak unit is characterized in that the horizontal streak is arranged to be hooked on the vertical streak, the vertical streak unit is provided with a hooking device for stopping the horizontal streak unit, and the gripping device is provided with an arm and an arm of the arm. The gripping tool is detachably provided at the tip, and the gripping tool is provided with a hook from which the reinforcing bar unit is hooked, protruding from the frame, and rocking bars provided above and below the frame sandwiching the hook. It is to make it the composition characterized by that.

[0008]

After the vertical streak unit gripped by the gripping device of the traveling vehicle is built along the mountain retaining wall to arrange the vertical streaks, the horizontal streak unit gripped by the gripping device of the traveling vehicle is hooked on the vertical streak. By arranging the horizontal bars, workability and workability can be improved.

Further, the horizontal stripes can be easily arranged by hooking the horizontal stripes unit on the latch provided in the vertical stripe unit.

Further, since the gripping device including the arm and the gripper can carry the reinforcing bar unit and perform the bar arrangement work, the worker can be released from heavy labor.

Further, by arranging the reinforcing bars by the gripping device of the traveling vehicle, scaffold installation, dismantling, refilling work, etc. are not required, and the site can be used widely and in an orderly manner, and safety management is facilitated.

[0012]

[Embodiment] The method for arranging the reinforcing bars of the underground wall structure will be described in detail below with reference to the drawings. 1 to 5 are cross-sectional views showing a method of arranging the reinforcing bars of the underground wall structure.

In the present embodiment, a case will be described in which a subterranean outer wall frame is constructed along the periphery of a retaining wall. As shown in FIG. 1, the reinforcing bars 3 are provided on the concrete foundation 2 along the retaining wall 1 at appropriate intervals.

Then, as shown in FIG.
The vertical stripe unit 6 of the underground wall structure is gripped by the gripping device 5 of FIG.

As shown in FIG. 2, the arm 7 of the gripping device 5 is installed at a predetermined height and the cylinder 8 at the tip rotates the gripping tool 9 to connect the hook 9a to the vertical streak unit 6. Hook on the muscle 6a.

The gripping tool 9 is for a vertical streak unit and is detachably attached to the tip of the arm 7.

As shown in FIG. 8, the gripping tool 9 is composed of a hook 9a protruding from the center of the frame 10 and rocking bars 11 provided above and below the frame 10 sandwiching the hook 9a.

A lock pin 9b is removably attached to the fixed plate 17 on which the hook 9a is provided so as to project, when the vertical streak unit 6 is locked.

The rocking bar 11 is for preventing the vertical streak unit 6 which is hooked on the hook 9a from rotating, and is provided with a stop piece 18 for preventing lateral displacement.

As shown in (1) of FIG. 6, the vertical streak unit 6 has four vertical streaks 6b connected by a connecting streak 6a, and a hook 13 for hooking the horizontal streak unit 12 in the longitudinal direction thereof. I have it.

As shown in (1) of FIG. 9, the latch 13 has a U-shaped holding tool 13a provided with a latching piece 13b, and a binding pin 13c is attached to the tip of the latching piece 13b. Tightening bolts 13d are attached to the opposite sides.

Then, as shown in (2) of the same drawing, after the holding tool 13 is fitted on the vertical line 6b, the hooking piece 13b is bound by the binding pin 13c and fixed by the tightening bolt 13d. The binding pin 13c and the tightening bolt 13d are provided on the rib 6 of the vertical stripe 6b.
Since it is hooked on c, the hook 13 does not slip off.

Next, as shown in FIG. 3, the vertical stripe unit 6
Is embedded and joined to the bar 3, and the upper portion thereof is supported by the pressing member 14. Then, the vertical streak units 6 are sequentially built along the mountain stopper wall 1 to arrange the vertical stripes around the mountain stopper wall 1.

Next, the gripper 9 for the vertical streak unit is removed, and the gripper 1 for the horizontal streak unit as shown in FIG.
Attach 5.

In this gripping tool 15, a hook 16a is provided at the center of two flat plates 16, and the upper and lower parts of the flat plates 16 serve as a rocking bar 11 for preventing the horizontal bar unit 12 from rotating.

The horizontal streak unit 12 has the same structure as the vertical streak unit 6, as shown in FIG. 7B.

Then, as shown in FIG. 4, the horizontal streak unit 12 is gripped in the same manner as the vertical streak unit 6 to hold the vertical streak 6b.
Hang it on the hooking tool 13 of.

Thus, the horizontal streak unit 12 is connected to the vertical streak 6a.
The bar is laid in the upper direction, and it is sequentially advanced along the mountain stopper wall 1 to arrange the horizontal streaks.

Further, the horizontal streak unit 12 can be gripped not only by the gripping tool 15 for the horizontal streak unit but also by the gripping tool 9 for the vertical streak unit. Further, similarly to the above, the vertical streak unit 6 can also be gripped by the gripper 15 for the horizontal streak unit.

As described above, after arranging the vertical bars and the horizontal bars, a formwork is assembled along these reinforcing bars, and concrete is placed in the formwork to construct a subterranean outer wall frame body.

EFFECTS OF THE INVENTION A vertical streak unit gripped by a gripping device of a traveling vehicle is installed along a mountain retaining wall to arrange a vertical streak, and then a horizontal streak unit gripped by a gripping device of the traveling vehicle is attached to the vertical streak. The workability and the workability can be improved by arranging the horizontal stirrups by fastening them.

The horizontal streak can be easily arranged by hooking the horizontal streak unit on the hooking tool provided in the vertical streak unit.

Since the gripping device composed of the arm and the gripping tool can carry the reinforcing bar unit and carry out the work of arranging, the worker can be released from heavy labor.

By arranging the reinforcing bars with the gripping device of the traveling vehicle, scaffolding installation, dismantling, refilling work, etc. are unnecessary, and the site can be used widely and in an orderly manner, and safety management is facilitated.
