DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting pipes, and more particularly to a structure in which pipes can be easily and securely mounted, and a protruding portion can be reduced or eliminated.

[0002]

2. Description of the Related Art For example, in a building structure such as a high-rise apartment, various devices such as an air conditioner, an antenna, and a pool are installed on the roof, and these devices are connected to each room by cables, water pipes, gas pipes, and the like. It is widely done.

Usually, when laying cables, water pipes, gas pipes, and the like on a roof, concrete is cast on the roof to make a base, and a clip is inserted into the base to be solidified. Although the support of gas pipes and the like has been performed, a series of operations is complicated, and a long time is required to complete the operations.

[0004] Therefore, a method using a concrete support block produced in advance in a factory has been developed. That is,
As shown in FIG. 10, a locking groove 110 is formed on the upper surface of the support block 100 so as to extend in the longitudinal direction.
At the upper edges of both sides of each of the 00, a shape in which the protruding ridges 111, 111 protrude inward is manufactured at a factory, and a plurality of support blocks 1 are formed.
00... Are installed along the rooftop laying line and spaced from each other, and cables, water pipes, gas pipes, and the like (hereinafter, referred to as pipes) in which cables are inserted on the support block 100.
P is placed on the base 13 of the pair of clip plates 130, 130.
1, 131 is inserted into the locking groove 110 from the side, or inserted from above into the locking groove 110 in parallel to the longitudinal direction and rotated so as to be perpendicular to the longitudinal direction to prevent it from falling off, In this method, the piping P is sandwiched between a pair of clip plates 130, 130, and the rising portions 132, 132 at the upper ends of the clip plates 130, 130 are mutually fastened with bolts 120 and female screws (or nuts) to attach the piping P. .

[0005]

However, in the conventional mounting structure, the pipes P are sandwiched between the pair of clip plates 130, 130 and tightened by the bolts 120.
It is necessary to considerably lengthen the shaft portion 121, and after tightening, the bolt shaft portion 121 protrudes from the clip plate 130 in a direction perpendicular to the pipes P, for example, about 10 to 12 mm. The rising portions 132, 132 protrude upward from the pipes P, for example, by about 15 mm, and there is a possibility that the body, clothes, etc. may be caught by these, and there is a concern that injuries or the like due to mischief of children may occur.

A plurality of pipes P having different outer diameters are often supported side by side on one support block 100.
In such a case, the head of the bolt 120 for mounting the small-diameter pipes is hidden by the large-diameter pipes or the clip plate for mounting the same, so that a sufficient gap cannot be secured between the tip of the adjacent bolt shaft 121. However, the driver cannot be inserted into the bolt head from the side, and a tool such as a spanner or a wrench must be used, which is very inconvenient.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a pipe mounting structure that can easily and reliably mount pipes and that can reduce or eliminate a protruding portion. I do.

[0008]

SUMMARY OF THE INVENTION Therefore, a pipe mounting structure according to the present invention is a pipe mounting structure in which pipes are mounted on a support block and mounted on the upper surface of the support block. A locking groove whose groove width is smaller than the groove width at the bottom is formed to extend in the longitudinal direction, and the bases of a pair of clip plates are inserted into the locking grooves so as to be prevented from coming off, and the pair of the locking plates are prevented from coming off. While the pipes placed on the support block are sandwiched between the clip plates, a locking portion is formed at the upper edge of the pair of clip plates, and the pipes are sandwiched between the pair of clip plates. In this state, the fasteners are co-locked to the pair of locking portions, whereby the upper edges of the pair of clip plates are mutually tightened, and the pipes are attached to the support block. .

One of the features of the present invention is that a locking portion is formed at the upper edge of a pair of clip plates, and a fastening portion is co-locked with the locking portion to fasten the pair of clip plates.
This eliminates the need for bolts as in the conventional case, and the locking portion can be formed by co-locking the tightening portion, so there is no need to increase the size as in the conventional rising portion. It is possible to eliminate concerns such as danger of snagging the body or clothes and injury to children.

Further, since bolts are not required, even when a plurality of pipes are arranged on one support block, it is not necessary to use a tool such as a screwdriver, a spanner, a monkey wrench, and the workability is very good.

Further, when it is necessary to remove the piping,
With the conventional mounting structure, if a considerable period of time elapses after mounting, the bolts will rust and it will be difficult to remove them. However, in the present invention, bolts are not used, and the fastening part is locked together with the locking part It is also easy to remove the piping because it is only done.

Here, the piping means a piping through which a power cable, a wiring and the like are inserted, a water pipe, a gas pipe and the like. The locking groove of the support block only needs to have a groove width at the upper end smaller than the groove width at the bottom. For example, it may be a so-called dovetail groove. It may be shaped to project toward. The locking portion and the fastening portion can co-lock the fastening portion with the pair of locking portions, and as long as the protruding portion does not become large, the form is not particularly limited, and any shape can be adopted. It is possible.

For example, a hole may be formed in a pair of locking portions so as to face each other, and a fastening plate may be inserted into the opposite holes and locked together. In this case, if the wedge is inserted into the lower side of the fastening plate, the pipes can be reliably fixed. Alternatively, a pair of locking plates may be co-locked with bolts and nuts (or female threads), and a wedge may be inserted into the lower side of the bolt shaft to attach piping.

[0014] Further, the locking portion has a substantially inverted L-shape in which the upper half projects laterally, and the fastener has a U-shaped portion on both sides. The fittings can be co-locked to the pair of locking sections by fitting the pipes into the substantially L-shaped side projections of the sections from the longitudinal direction.

In this case, in order to securely mount the pipes, a raised portion protruding downward is formed at the center of the fastener, so that the space is surrounded by a pair of locking portions, the fastener, and the pipes. It is preferable to fix the piping by inserting a wedge.

In the above, the fastening portion is co-locked with the locking portion at the upper end of the pair of clip plates. However, the locking portion is formed on one clip plate and the locking receiving portion is formed on the other clip plate. , Can be mutually locked.

That is, according to the pipe mounting structure of the present invention, in a pipe mounting structure in which the pipes are mounted on a support block and mounted, the upper end of the support block has a groove width at the upper end which is closer to the bottom. A locking groove smaller than the width of the groove is formed to extend in the longitudinal direction, and a base of a pair of clip plates is inserted into the locking groove so as to be prevented from falling upward, and between the pair of clip plates, While the pipes placed on the support block are sandwiched, a locking portion is formed on the upper edge of one of the pair of clip plates, and a locking receiving portion is formed on the other clip plate. When the pipes are sandwiched between the pair of clip plates, the locking portions are locked to the lock receiving portions, so that upper end edges of the pair of clip plates are mutually fastened, so that the piping Is attached to the support block And said that you are.

The locking portion and the locking receiving portion can lock both, and the shape is not particularly limited as long as the protruding portion does not become large, and any shape can be adopted. .

For example, the locking portion has a form in which a vertical wall portion is bent toward the distal end, while the locking receiving portion has a hole through which the locking portion can be inserted, and the locking portion is inserted through the hole. Then, the vertical wall portion can be hooked on the periphery of the hole. The vertical wall portion may be curved upward or downward.

In this case, in order to securely mount the pipes, the vertical wall of the locking portion is inserted between the locking portion, the locking receiving portion and the piping or between the hole and the locking portion. It may further comprise a wedge for holding the portion hooked on the periphery of the hole.

In the above two examples, a pair of clip plates is used. However, a method using a wire spring clip can be adopted.

That is, in the pipe mounting structure according to the present invention, in a pipe mounting structure in which pipes are mounted on a support block and mounted, the support block has a locking groove formed on an upper surface thereof in a longitudinal direction. The locking groove is formed to have a protruding ridge projecting inward at both upper end edges of the locking groove, while the pipes mounted on the support block have a substantially inverted U-shape. A wire spring clip is attached, and hook portions are bent at lower end portions of both legs of the wire spring clip,
The pipes are attached to the support block by the hook portions being hooked on the protrusions of the locking groove.

The pipes may be attached to the support block with a single wire spring clip. However, for more secure attachment, the pipes are preferably attached to the support block with a pair of wire spring clips. The wire spring clip is formed in a generally inverted U-shape with spring steel or the like and has a shape having a hook portion by bending the lower end portions of both legs, and hooks the hook portion to the ridge portion by the spring force of the hook portion at the lower end. However, if the spring force is set to be strong to ensure the attachment, a large force is required for hooking and detaching. Therefore, when the wire spring clip is formed with a spring portion that pulls up the hook portion at the lower end in the middle of one of the substantially inverted U-shaped legs, the hook portion is easily hooked on the ridge by deforming the spring portion. , While you can remove this,
It can be reliably held in the hooked state by the spring force of the spring portion.

The spring portion may be coil-shaped, but when the base of the hooking portion is pulled upward, the tip of the hooking portion may come off from the projecting portion depending on the shape of the projecting portion.
Therefore, when the spring portion is formed in a semi-annular or annular shape and the distal end side is pivotally urged upward about the base side of the hook portion, the hook portion can be reliably prevented from coming off.

Although the present invention is directed to a pipe mounting structure, a mounting tool used in such a mounting structure is also novel.

That is, according to the present invention, the pipes are placed on a support block formed on the upper surface with a locking groove having an upper end groove width smaller than the bottom groove width and extending in the longitudinal direction. A mounting tool used for mounting, wherein a locking portion is formed at an upper end edge, a base portion is inserted into the locking groove and is prevented from falling upward, and a pair of clip plates for holding piping, And a fastening tool co-locked to the locking portion of the pair and fastening the upper end edges of the pair of clip plates to each other.

Further, according to the present invention, the pipes are placed on the support block formed on the upper surface with the locking groove having the upper end groove width smaller than the bottom groove width extending in the longitudinal direction. A mounting tool used for mounting, wherein a locking portion is formed at an upper edge, a first clip plate whose base is inserted into the locking groove and is prevented from falling upward, And a second clip plate that clamps the piping together with the first clip plate, wherein a lock receiving portion capable of locking the stop portion is formed, a base portion is inserted into the locking groove and is prevented from being pulled upward. Can be provided.

Further, according to the present invention, a support block having a locking groove formed on the upper surface thereof extending in the longitudinal direction, and a ridge portion protruding inward at both upper end edges of the locking groove. above,
It is a fixture used when mounting with mounting piping,
A substantially inverted U-shape is formed, and hook portions are bent at lower end portions of the both leg portions, the hook portions are attached to pipes mounted on the support block, and the hook portions are formed as ridges of the locking groove. Can be provided with a pipe fitting having a wire spring clip for attaching the pipes to the support block.

Note that the specific structure and details of each of the above-mentioned fittings are the same as in the case of the mounting structure.
