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 of an underground outer wall frame.

[0002]

2. Description of the Related Art Generally, an underground outer wall skeleton is an important part in structure, and has a large amount of reinforcement because it is subjected to surrounding earth pressure.

[0003] This construction has been carried out by scaffolding work mainly by human power, because it is difficult to carry in and attach large members due to the arrest material, and the height of the underground outer wall frame is high.

[0004] In this work, as shown in FIG. 10, two or three people are arranged as a set, and the reinforcing bars 30 are delivered one by one over the scaffold 20.

[0005]

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

The present invention has been made in view of such a problem, and an object of the present invention is to improve workability and workability, and to improve the workability of a worker of an underground outer wall frame for reducing the work of an operator. The purpose of the present invention is to provide a bar arrangement method.

[0007]

Means for solving the above problems are as follows. The invention according to claim 1 is a method for arranging reinforcing bars of an underground outer wall frame constructed along a retaining wall of a root cut. And a vertical bar unit with vertical bars with hooks connected by connecting bars.
And the horizontal muscle unit where the horizontal muscles are connected by connecting muscles
This vertical streak unit is mounted on a trolley
From the state, grip with the hook of the gripper rotated by the cylinder
Bars in the vertical position and above and below the hook
Built along the retaining wall while supporting it with vertical streaks
Connecting the lower part of the unit to the concrete foundation with stirrups
At the same time, after fixing the upper part to the retaining wall with the holding material,
Move the horizontal streak unit from the horizontal position
Hold with the hook of the gripping tool rotated with
And supported by vibration bars above and below the hook
The invention is also characterized in that it is hooked on a hook of a vertical streak unit.
The stop bar is provided with a stop piece protruding therefrom .

[0008]

The vertical streak unit gripped by the gripping device of the traveling vehicle is erected along the retaining wall to arrange the vertical stripes, and then the horizontal stripe unit gripped by the gripping device of the traveling vehicle is hung on the vertical stripe. By arranging the horizontal streaks, workability and workability can be improved.

Further, the horizontal streak unit can be easily arranged by hooking the horizontal streak unit to the hook provided on the vertical streak unit.

[0010] Further, since the rebar unit can be transported and rebar-arranged by the gripping device including the arm and the gripper, the worker can be released from heavy labor.

In addition, by arranging the reinforcing bars with the gripping device of the traveling vehicle, installation, dismantling, and changing of scaffolds are not required, so that the site can be used more widely and orderly, and safety management can be facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of arranging reinforcing bars of an underground outer wall frame will be described below in detail with reference to the drawings. 1 to 5 are sectional views showing a method of arranging reinforcing bars of an underground outer wall skeleton.

In this embodiment, a case where an underground outer wall frame is constructed along the periphery of a retaining wall will be described. As shown in FIG. 1, a reinforcing bar 3 is provided on the concrete foundation 2 along the retaining wall 1 at appropriate intervals.

Then, as shown in FIG.
The vertical streak unit 6 of the underground outer wall skeleton is gripped by the gripping device 5 of (1).

[0015] This gripping, as shown in FIG. 2, with placing the arm 7 of the gripping device 5 to a predetermined height, the hook 9a of the gripper 9 rotated by the cylinder 8 of the tip, base
Connecting bar 6a of the vertical bar unit 6 placed horizontally on the car
Hook on.

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

As shown in FIG. 8, the gripper 9 comprises a hook 9a projecting 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 attached to the fixed plate 17 on which the hook 9a protrudes, so that the lock pin 9b can protrude and retract, and projects when the vertical streak unit 6 is latched.

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

[0020] The longitudinal muscle unit 6, as shown in (1) in FIG. 7, four vertical stripes 6b connected by connecting muscles 6a, the latching member 13 for hooking the horizontal stripes unit 12 in the longitudinal direction Have.

[0021] The locking member 13, as shown in (1) in FIG. 6, comprises a pincer 13a is hanging piece 13b of the U-shaped bundling pin 13c at the tip of該掛stop piece 13b is, its Tightening bolts 13d are attached to the opposite sides, respectively.

Then, as shown in (2) of the figure, after the holding member 13 is fitted to the vertical streak 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 connected to the rib 6
Since the hook 13 is hooked on the hook c, the hook 13 does not slip off.

Next, as shown in FIG.
Is vertically installed on the retaining wall 1 and joined to the streak 3, and the upper part thereof is supported by the pressing member 14.
In this way, the vertical streak units 6 are sequentially built along the retaining wall 1, and the vertical streaks are arranged .

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

The gripper 15 has a hook 16a at the center of two flat plates 16, and upper and lower portions of the flat plate 16 serve as a rocking bar 11 for preventing the rotation of the horizontal streak unit 12.

The horizontal streak unit 12 has the same configuration as the vertical streak unit 6, as shown in FIG. 7 (2).

Then, as shown in FIG. 4, the horizontal streak unit 12 is gripped by the same method as the vertical streak unit 6, and
On the hook 13.

As described above, the horizontal streak unit 12 is connected to the vertical streak 6a.
, And successively proceed along the retaining wall 1, thereby arranging the horizontal streaks.

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

As described above, after arranging the vertical bars and the horizontal bars, the formwork is assembled along these reinforcing bars, and concrete is poured into the formwork, whereby the underground outer wall frame can be constructed.

[0031]

As described above, since the vertical and horizontal streaks are unitized and arranged, it is possible to improve the workability and workability of the work of arranging the vertical and horizontal streaks. Also vertical streak unit or horizontal
Hold the muscle unit with the hook of the gripper of the traveling vehicle, and
By supporting with a vibration bar above and below the hook,
Rotation of the vertical or horizontal muscle unit in the gripper
Can be prevented. The vertical muscle unit and the horizontal muscle unit
The grip from the horizontal state to the vertical state
can do.

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

By the gripping device including the arm and the gripper, the rebar unit can be transported and the bar arrangement work can be performed, so that the worker can be released from heavy labor.

By arranging the reinforcing bars with the gripping device of the traveling vehicle, scaffold installation, disassembly, and rearrangement work are not required, and the site can be used more widely and orderly, and safety management is facilitated.
