Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe support.

[0002]

2. Description of the Related Art FIG. 5 shows an example of a conventional pipe support, which is made of concrete or steel frame having the same height on the ground along a route in which the pipe 1 is horizontally arranged. A base 2 made of, for example, a product is provided at a predetermined interval, a support base 3 made of an I-shaped steel or the like is horizontally fixed on the base 2, and the pipe 1 is placed on the support base 3. .

The pipe 1 has a weight corresponding to the diameter and thickness of the pipe, and the weight of the fluid flowing inside is also added. Therefore, the pipe 1 has a relatively large weight and in a normal state, the support base. The pipe 1 does not move only by being placed on it, and therefore the movement of the pipe 1 is not restricted.

In the above-mentioned piping support of FIG. 5, when uneven settlement X of the foundation 2 (intermediate foundation 2 of the three foundations 2 shown in FIG. 5) occurs due to ground subsidence or the like. The support base 3 and piping 1 on the submerged foundation 2
A gap S is created between Thus, due to the uneven settlement X of the foundation 2, a gap S is formed between the support base 3 and the pipe 1.
If the above occurs, the submerged foundation 2 cannot support the pipe 1 and thus the interval for supporting the pipe 1 is doubled or more.

Further, it is conceivable to fix the pipe 1 on the support base 3 in an attempt to solve the problem that the gap S is generated between the pipe 1 and the support base 3. As described above, since the pipe 1 is forcibly bent due to the uneven settlement X of the foundation 2, there is a problem that bending stress and tensile stress act on the pipe 1.

For this reason, it has been considered to use a pile driving foundation so as not to cause the uneven settlement X of the foundation 2, but the pile driving foundation has a problem that it takes a lot of time and a huge cost for the pile driving work. Yes, it is practically difficult to hire.

Furthermore, the uneven settlement X of the foundation 2 as described above
In order to allow the pipe 1 to be supported on the foundation 2 even when the above occurs, a spring type pipe support 4 as shown in FIG. 6 has been adopted.

As shown in FIG. 6, the spring type pipe support 4 is provided with a base plate 6 mounted by bolts 5 on a support base 3 fixed horizontally on a base 2, and on the base plate 6, a cylinder is mounted. The column 7 is erected, and the outer cylinder 8 is concentrically provided on the outer periphery of the column 7 with a required interval.

Further, a guide tube 9 which can freely move up and down along the outer circumference of the support column 7 is provided, and a screw portion 10 is screwed onto the upper portion of the guide tube 9 to adjust the screw-in amount to thereby move in the vertical direction. Horizontal support stand 11 with adjustable height position
Is provided.

A spring 12 is inserted between the guide cylinder 9 and the outer cylinder 8, and a stopper 13 for abutting on the spring 12 to press the spring 12 downward.
Is fixed to the outer circumference of the guide cylinder 9.

In the structure shown in FIG. 6, the spring-type pipe support 4 having the spring 12 having the elastic force corresponding to the weight of the pipe 1 is fixed on the support base 3 by the bolts 5, and is mounted on the support base 11. When the pipe 1 is placed, the pipe 1
The weight allows the spring 12 to be stably supported at a position where the spring 12 is bent by a predetermined amount.

On the other hand, the spring type pipe support 4 shown in FIG.
In the case where the uneven settlement X as shown in FIG. 5 occurs, it is prevented that the gap S is formed on the lower surface of the pipe 1 by extending the spring 12 by the distance of the uneven settlement X. The load of the pipe 1 is continuously supported by the required elastic force of the pipe 12.

[0013]

However, in the conventional spring type pipe support 4 shown in FIG. 6, there is a problem that the structure is complicated and expensive, and the strength of the spring 12 corresponding to the weight of the pipe 1 is increased. Therefore, there is a problem in that the application is troublesome because it has to be used, and the maintenance is troublesome.

The present invention has been made in view of the above circumstances, and has a simple structure, and even when uneven settlement occurs, the pipe can be fixedly supported at the height position before the uneven settlement and supported. It is intended to provide support.

[0015]

The pipe support of the present invention is a pipe support configured to support horizontally installed pipes on a foundation arranged at required intervals.
A support table installed substantially horizontally on the foundation, and a pair of slidable surfaces on the upper surface having slanted surfaces that incline from one side to the other so that the slanted surfaces face each other. A wedge block and a wire whose one end is fixed to each of the wedge blocks and whose other end extends from the lower side end of the inclined surface by a desired length, and the lower surface of the pipe faces each wedge block. After arranging the pair of wedge blocks so as to be supported by the inclined surfaces, and winding the other end side of the wire having one end side fixed to each wedge block around the upper outer periphery of the pipe from the extending direction, It is characterized in that it is fixed on the support base at an outer position of the wedge block.

Further, the present invention is characterized in that it is provided with a detachable restraint tool for restraining the wedge blocks at predetermined intervals when the pipes are placed on the two wedge blocks. .

Further, the wire is provided with a length adjusting means, and further, the length adjusting means penetrates through the support base and the other end of the wire is fixed to the upper end of the bolt, and the support of the bolt. It is characterized by comprising a nut for adjusting the protruding length of the table top.

In the present invention, the pipe is placed on the support base by a pair of wedge blocks and a wire having one end fixed to the wedge block and the other end extending a required length from the lower side end of the inclined surface. Since it is tied up, when uneven settlement occurs, the wire is pulled to open the gap between the pipe and the support base by the distance of uneven settlement, and the pulling force pushes the inclined surface to the lower surface of the pipe. By moving the wedge block so as to be squeezed, it is possible to continuously tie and support the pipe at the height position before the occurrence of uneven settlement, and it is possible to implement it at a low cost with a simple configuration. In addition, it has a configuration in which failure does not easily occur and maintenance is easy.

Further, when a detachable restraint is provided for restraining the wedge blocks at predetermined intervals when placing the pipes on the two wedge blocks, the pipes are supported at the same height position. This makes installation work easier.

If the wire is provided with the length adjusting means, it is possible to eliminate the slack of the wire and adjust the supporting height of the pipe. If the bolt is fixed at the end side and the nut for adjusting the protruding length of the upper portion of the support base of the bolt is used, the structure is simple and the handling is easy.
