Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pair of side plates which are arranged side by side at right and left intervals to form left and right side surfaces of a piping space, and the piping space is mounted over the pair of side plates. A first pipe cover provided with a support member capable of supporting pipes disposed on the first pipe cover and a lid member detachable from the pair of side plates, and a second pipe cover are provided. The present invention relates to a pipe cover structure in which two pipe covers are arranged along the longitudinal direction thereof, and respective side plates adjacent to each other along the longitudinal direction of the pipe covers are separately connected together with a connecting member.

[0002]

2. Description of the Related Art Conventionally, as this type of pipe cover structure, as shown in FIG. 4, a first interval dimension W1 between the side plates 7 of the first pipe cover 3A and a second gap size of the second pipe cover 3B. The second spacing dimension W2 between the side plates 7 is set to the same value, and the connecting member 10 includes an attachment portion 20 attached to the side plates 7 of the both pipe covers 3A and 3B, and an outer peripheral surface of the side plate 10. Some of them were formed so as to contact each other.

[0003]

In general, for efficient piping, it is desirable to make a laying linear plan so as to make as little a bent portion as is necessary for pipe connection processing as much as possible. In the case of laying a plurality of pipes, in order to save as much space as possible, all the pipes should be put together and placed in the pipe cover, and the branch pipes should be appropriately branched from the necessary places. Is often done. In this case, the number of pipes to be accommodated between the upper side portion and the lower side portion in the pipe cover decreases as the lower side increases. According to the above-described conventional pipe cover structure, since the first pipe cover and the second pipe cover are formed to have the same width, as described above, when the number of pipes to be accommodated differs depending on the location, However, it occupies the same width of the piping path, which has the drawback that it is difficult to save space, and in places where the number of the accommodated piping is reduced, extra space is covered with the piping cover, which is uneconomical. There is a drawback that tends to be.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pipe cover structure which can solve the above-mentioned drawbacks, reduce wasted piping space, and more efficiently protect pipes.

[Means for Solving the Problems]

[Structure] As shown in FIG. 3, a characteristic structure of the invention according to claim 1 includes a pair of side plates 7 which are juxtaposed at right and left intervals to form left and right side surfaces of the piping space 1, and the pair of side plates. A support member 8 capable of supporting the pipe 2 disposed in the pipe space 1 while being attached over the side plate 7;
A first pipe cover 3A provided with a lid member 9 detachable from the pair of side plates 7 and a second pipe cover 3B are provided, and the first pipe cover 3A and the second pipe cover 3B are separated from each other. Lined up along the longitudinal direction, each pipe cover 3A ·
In a pipe cover structure in which the side plates 7 adjacent to each other along the longitudinal direction of 3B are separately connected together with a connecting member 10, the first space dimension W1 between the side plates 7 of the first pipe cover 3A is set to be equal to the width W1. In comparison, the second pipe cover 3B
The second interval dimension W2 between the side plates 7 is set to be small, and the width step portion 10c corresponding to the difference between the first interval dimension W1 and the second interval dimension W2 is set to one of the left and right connecting members 10. It is located on one side.

As shown in FIG. 2, the connecting member 10 having the stepped portion 10c is provided with a connecting portion attached to the side plate 7 of the second pipe cover 3B. 14 is formed so as to contact the inner peripheral surface of the side plate 7.

[0007] As described above, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the accompanying drawings.

According to a feature of the invention, the second pipe cover has a second space between the side plates of the second pipe cover compared to a first distance between the side plates of the first pipe cover. Since the interval dimension is set to be small, and a width step portion corresponding to the difference between the first interval dimension and the second interval dimension is provided on one of the left and right connecting members, The piping space of the second piping cover can be set smaller than the piping space, and as described above, when the number of piping to be accommodated differs depending on the location, it is possible to secure the piping space corresponding to each number. This makes it possible to accommodate and protect the pipes in a less wasteful state. Further, since the width step portion is provided on one connecting member, the other connecting member can also serve as a conventional connecting member. For example, the first pipe cover and the second pipe cover are coaxially arranged. In order to dispose them, a width step portion is provided on both the left and right connecting members (hereinafter referred to as a comparative example).
It is possible to improve economic efficiency. Furthermore, since the range in which the straight piping can be performed in the piping space extending between the two pipe covers can be collectively secured on the other connecting member side,
In addition to making it easier to make a piping arrangement plan with fewer bent portions, the branch piping space can also be concentrated on the one connecting member side, so that it becomes easier to secure a working space for branch piping, and to perform piping work. The efficiency can be improved as compared with the comparative example. From the above results, it is possible to save space for the installation space of the pipe cover, to suppress an increase in cost due to the space saving, and to facilitate the piping work, thereby improving the overall economic efficiency. It is possible to do.

According to the characteristic configuration of the second aspect of the present invention, the connecting member having the width step portion has an attachment portion attached to the side plate of the second pipe cover on the inner peripheral surface of the side plate. Since it is formed so as to abut, the edge portion of the side plate connected to the connecting member having the step portion is brought into contact with the width step portion, and positioning in the longitudinal direction is simplified. And the efficiency of the pipe cover assembling operation can be improved.
