Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of assembling a formwork for an underground wall.

[0002]

2. Description of the Related Art Generally, the underground outer wall is an important structural part, and the amount of reinforcement is large because it receives the earth pressure around it.

Construction of this underground outer wall is carried out by manpower-based scaffolding work because it is difficult to carry in and install large members due to obstacles to the mountain stopper and the floor height of the underground outer wall is high. .

In this work, the method of assembling the formwork for the underground outer wall is as shown in FIG.
The panel 30 for the formwork was handed over one by one over the scaffold 20.

[0005]

However, the method of assembling the formwork for the outer wall of the underground as described above is not efficient because it is a work mainly by human power, and moreover, the work is performed in a narrow space between the wall reinforcement and the scaffolding. It forced the workers to do very difficult work, including the transportation of.

The present invention has been made in view of the above problems, and an object of the present invention is to improve the workability and the workability of the work and to provide a formwork for the outer wall of the underground for reducing the work of the worker. It is to provide an assembling method.

[0007]

A method for assembling a formwork for an underground outer wall according to the present invention for achieving the above-mentioned object is such that a formwork panel is tilted and held by a gripping device of a traveling vehicle, and the formwork panel is attached to the formwork panel. It is characterized in that a separator protruding from the mountain retaining wall is inserted and built in, and the formwork panel is formed by combining a plurality of panels, and the formwork panel is built with an appropriate interval. Later, the gap portion is closed and built up with another form panel, and the gripping device comprises an arm and a gripping tool rotatably provided at the tip of the arm. The present invention is characterized in that a hook for locking the formwork unit is projectingly provided on the frame, and a lock pin is provided so as to be retractable on the frame having the hook projecting.

[0008]

The grip panel of the traveling vehicle is used to incline and grip the mold panel, and the separator projecting from the mountain retaining wall is inserted into the mold panel and built in. Since assembly work can be done, workability and workability can be improved, and there is no need for scaffolding installation, dismantling, refilling work, etc., and the site can be used widely and in an orderly manner, and safety management is also easy. Become.

Further, since the formwork panel is formed by combining a plurality of panels, it is possible to form a formwork panel having an arbitrary size.

Further, the work of assembling can be facilitated by building the form frame panel with an appropriate space and then building the space by closing the space with another form panel.

The gripping device is composed of an arm and a gripping tool rotatably provided at the tip of the arm, and the gripping tool is provided with a hook for locking the form unit on the frame and the hook. Since the lock pin is provided on the protruding frame so as to be retractable, the form panel can be easily gripped and can be freely rotated in the front, rear, left, and right directions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a method of assembling a formwork for an underground wall will be described in detail below with reference to the drawings. 1 is a front view of a form panel, FIG. 2 is a side view of a traveling vehicle, FIG. 3 is a perspective view of a gripping device, FIG. 4 is a plan view thereof, and FIG. 5 is a side view thereof.

The present invention is a formwork panel 1 as shown in FIG.
This formwork panel 1 is formed by connecting four panels 1a in the horizontal direction with a connecting rod 2 and further connecting them in the vertical direction with a connecting rod 2.

The formwork panel 1 is gripped by a gripping device 4 of a traveling vehicle 3 as shown in FIG. 2 and built as a wall formwork.

The gripping device 4 includes an arm 5 and the arm 5
And a gripping tool 6 provided at the tip of the gripping tool 6.
Is attached to a rotating plate 7 at the tip of the arm 5 so as to rotate in the front-back direction.

A gripping tool 6 is attached to the rotating plate 7 by a support shaft 9 so as to be rotatable in a lateral direction, and upper and lower hooks 10 are projected on a frame 8 of the gripping tool 6, and the hook 10 is projected. The lock pin 12 is attached to the fixed plate 11 so as to be retractable. This lock pin 12 is a formwork panel 1
When it is locked, it is retracted rearward, but when the frame panel 1 is locked, it projects.

Hereinafter, such a form panel 1 and a traveling vehicle 3 will be described.
About the method of assembling the formwork for the underground outer wall using
This will be described with reference to FIG.

First, as shown in FIG. 6, the arm 5 of the gripping device 4 is set at a predetermined height, and the rotating plate 7 is rotated forward to move the hook 10 of the gripping tool 6 to the form panel 1. Hook on the connecting rod 2.

After hooking the hook 10 on the connecting rod 2, the lock pin 12 is projected and locked so as not to come off. Next, as shown in FIG. 7, the rotating plate 7 is rotated toward the arm 5 to make the formwork panel 1 vertical, and the traveling vehicle 3 is moved to near the mountain retaining wall 13.

Subsequently, as shown in FIG. 8, the rotary plate 7 is further rotated to tilt the formwork panel 1 toward the arm 5 and the separator 14 projecting from the mountain stopper wall 13 is attached to the formwork panel 1. The form panel 1 is fixed by inserting it from the bottom in order and screwing.

In order to facilitate the assembling of the form panel 1, as shown in FIG. 9, the space 15 for one panel 1a is opened and incorporated.

After the form panel 1 is built, another form panel is built in the gap portion 15. The other form panel is also the separator 1 like the form panel 1.
Fix at 4.

In this way, the formwork panels 1 are sequentially built up to assemble the formwork for the outer wall, and concrete is poured into the formwork to construct the underground outer wall.

[0024]

EFFECTS OF THE INVENTION By tilting and holding a form frame panel with a gripping device of a traveling vehicle, and inserting a separator projecting from the mountain stopper wall into the form frame panel and building it, all the molds can be formed without relying on human power. Since the work of assembling the frame can be done, workability and workability can be improved, and there is no need for scaffolding installation, disassembly, refilling work, etc.
It can be used in an orderly manner, and safety management becomes easy.

Since the formwork panel is formed by combining a plurality of panels, a formwork panel of any size can be formed.

The work of assembling can be facilitated by building the form panel with an appropriate interval, and then closing the space with another form panel and building it.

The gripping device comprises an arm and a gripping tool rotatably provided at the tip of the arm. The gripping tool is provided with a hook for locking the form unit on the frame, and the hook is projected. Since the lock pin is provided so as to be retractable in the provided frame, the form panel can be easily gripped and can be freely rotated in the front, rear, left, and right directions.
