DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device for holding sheet piles erected on the left and right side walls of a groove when digging a groove to bury water and sewer pipes and various communication cables. It is about.

[0002]

2. Description of the Related Art Conventionally, when digging a trench in a road or the like in order to bury water and sewage pipes or communication cables, a metal sheet pile for preventing collapse of a side wall is provided. Although this sheet pile is reinforced with vertical and horizontal butter material, an operator has conventionally entered a narrow groove to construct this butter material.

[0003]

However, there is a problem that the work of constructing and disassembling a long flutter material vertically and horizontally in a narrow groove is very difficult, time-consuming and dangerous.
Therefore, the present invention easily and safely holds the sheet pile by inserting the framework assembled on the groove in advance into the groove, and thereafter operating the fluid pressure cylinder incorporated in the framework from the outside and pressing the horizontal flutter material toward the sheet pile. It is a primary object of the present invention to provide a support device capable of performing a simple structure.

[0004]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the sheet pile supporting device according to the present invention, the left and right sides of the plurality of horizontal fluttering members 1 arranged at predetermined intervals in the vertical direction are supported by two front and rear vertical columns 2. A pair of side frames 3, 3 and a fluid pressure cylinder 5 arranged between the left and right side frames 3, 3 to press the horizontal flaps 1... Against the sheet pile surface. The column 2 is connected to the column 2 via a connecting bracket 6 so that the vertical position can be adjusted and separated, and a horizontal stopper 7 is provided at the upper end of the column 2 to contact the upper edge of the sheet pile. .

[0005] The connecting fitting 6 is formed in a loop-like form through which the column 2 can be inserted, attached to the end face of the horizontal fluttering member 1, and provided with a number of pin holes provided in the column 2 along the vertical direction. By inserting a pin or bolt 8 into the optional hole 2a through the pin insertion hole 6a provided in the connection fitting 6, the horizontal fluttering member 1 and the support column 2 can be connected in a vertically adjustable and separable manner. Is good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the accompanying drawings. The sheet pile supporting device according to the present invention comprises a pair of left and right side frames in which both ends of a plurality of horizontal fluttering members 1 arranged at predetermined intervals in the vertical direction are supported by two front and rear vertical columns 2. And a fluid pressure cylinder 5 arranged between the left and right side frame bodies 3 and 3 to press the horizontal flaps 1... Against the surface of the sheet pile 4.

In this embodiment, the cross-sectional shape of the horizontal fluttering members 1 is a Japanese type, and the opening end face thereof is closed by a cap 9 as shown in FIG. The cap 9 is connected to a connection fitting 6 described later by a bolt 10 and a nut 11.
Is fixed to the horizontal fluttering material 1 together, but may be fixed by other means such as welding.

A connecting metal fitting 6 for connecting the horizontal fluttering material 1 and the support 2 has a substantially U-shape in plan view, and has a bent portion 6 at the leg end thereof.
At b, the bolt 10 and the nut 11 are fixed to the end face of the horizontal fluttering material 1 together with the cap 9. In addition, a pin or bolt 8 is inserted from a pin insertion hole 6a penetrating through the side wall of the connection fitting 6 into an arbitrary one of a large number of pin holes 2a. By
The horizontal fluttering member 1 and the column 2 are connected so as to be vertically adjustable and separable.

A hydraulic cylinder 5 is disposed between the left and right side frame members 3 and presses the horizontal flaps 1... Against the sheet pile surface, for example, a hydraulic cylinder or the like is used. Hooks 12 and 12 are provided. Further, a horizontal stopper 7 is provided at the upper end of the column 2 to be in contact with the upper edge of the sheet pile.

After the support device is assembled on the groove in advance, it is lowered into the groove by a crane or the like. At the time of assembling on the groove, the connection between the cylinder 5 and the lateral fluttering material 1 is performed by winding the hook 12 and the lateral fluttering material 1 with a wire 13 or the like as shown in FIG. You may make it connect with a connection means. Then, after the stoppers 7 of the columns 2 and 2 are lowered until they come into contact with the upper end of the sheet pile 4, the pistons of the cylinders are extended by operating the fluid pressure cylinders 5 from the outside, and the horizontal fluttering members 1 are placed on the sheet pile surface. Press on. By such an operation, an operator can easily and safely work from the outside without entering the narrow groove.

FIGS. 4 to 6 show another embodiment of the connecting fitting 6, in which the connecting fitting 6 is obstructed when the horizontal fluttering material 1 is separated from the column 2 and transported. It has a structure that can be stored in the end face of the horizontal fluttering material so that it does not become bent.
For this purpose, in this embodiment, the connecting fitting 6 is incorporated so as to be able to protrude and retract from the opening 9 a provided in the cap 9, and is constantly urged to the retracted position by the spring 13. In this retracted position, the distal end portion 6b of the connection fitting 6 is accommodated in the recess 9b on the front surface of the cap 9 so as not to protrude from the end face of the horizontal fluttering material 1. The cap 9 is fixed to the horizontal fluttering material 1 by bolts 10a and nuts 11a.

Although the representative embodiment of the present invention has been described above, the present invention is not necessarily limited to the above embodiment. For example, the horizontal fluttering material 1 is not limited to the Japanese type in the cross-sectional shape, but may have an H-shaped steel, a mouth steel, a U-shaped steel, or another cross-sectional shape. In addition, in the present invention, it is needless to say that the present invention can be carried out by appropriately changing the configuration within the scope of providing the components and having the effect.

[0013]

As described above, according to the present invention, the frame assembled on the groove in advance is inserted into the groove, and thereafter, the lateral pressure member is pressed against the sheet pile by operating the fluid pressure cylinder incorporated in the frame from the outside. As a result, the sheet pile support can be safely or externally constructed without the operator entering into the narrow groove, and since the structure is simple, it is easy to assemble and disassemble, thereby reducing the total cost. Has a significant effect.
