DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of first pipes which are provided with a pair of parent girder portions arranged in parallel at a distance from each other and which can support the piping along the longitudinal direction of the parent girder portions. The present invention relates to a piping support rack in which a support member is integrally connected so as to span the parent girder portion.

[0002]

2. Description of the Related Art Conventionally, as a pipe supporting rack of this type, as shown in FIG. 7, a rack main body R composed of a pair of parent girder portions 3 and a first pipe supporting member 4 is provided. In the case of supporting the pipes P in multiple stages, another rack body R is prepared, and a connecting column Q for connecting the rack bodies R apart from each other is provided, and the rack bodies R are integrally connected. For example, after supporting the pipes on the first-stage rack, if it becomes necessary to install additional pipes, the connection post is attached to the first-stage rack, and the connection post is connected through the connection post. Thus, the second stage rack is fixed and the piping is newly supported on the second stage rack.

[0003]

According to the above-mentioned conventional rack for supporting pipes, when the second rack is added, it is natural that a long rack is arranged at the mounting position. Although it is necessary to proceed with the work, for example, when the rack mounting target part is a pipe space of a building,
It is possible to carry in a long rack through the material entrance to the pipe space at the time of construction, but the material entrance is often remodeled into a small opening for inspection by the completion of the building. When adding pipes in multiple stages later, it is difficult to carry in an additional rack through the small opening. As a result, when performing additional piping after construction, it is necessary to provide a new rack entrance to the pipe space, which lengthens the piping work period,
There was a problem that the cost also increased.

[0004] Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a small installation space.
It is an object of the present invention to provide a piping support rack that facilitates efficient addition of a rack.

[0005]

[Structure] As shown in FIGS. 1 to 5, a characteristic structure of a first aspect of the present invention is to provide a pair of parent girder portions 3 in parallel at a distance from each other. A plurality of first pipe support members 4 which can be freely supported along the longitudinal direction of the parent girder part 3 and are integrally connected in a state extending over the parent girder part 3; A plurality of portal-shaped second pipe support members 5 that can freely support the pipe P so as to overlap the first pipe support space V1 by the pipe support member 4 are spaced apart from the parent girder portion 3 in the longitudinal direction. It is in a place where it is connected detachably.

As shown in FIGS. 1 to 5, the second embodiment of the present invention is characterized in that the second pipe support member 5 is formed by forming a pipe support portion 5a in a gate-shaped top portion, and The mounting portions 5b which can be attached to and detached from the main girder portion 3 are separately formed on both of the gate-shaped legs.

[0007] The characteristic structure of the invention of claim 3 is shown in Figs.
As shown in FIG. 6, a fall prevention mechanism T that can prevent the second pipe support member 5 from falling down along the longitudinal direction of the parent girder part 3 is provided on a leg of the second pipe support member 5. It is where it is formed.

As a feature of the invention according to a fourth aspect, as shown in FIGS. 1 to 5, in order to constitute the overturn prevention mechanism T, the second pipe support member 5 is formed of sheet metal, and both sides of the leg portion are formed. A bent reinforcing portion 9 which is formed by bending in the interval direction of the parent girder portion 3 is separately formed on an edge portion, and the edge of the bent reinforcing portion 9 abuts on the upper side of the main girder portion 3 to form a second reinforcing portion. This is where the two-pipe support member 5 is prevented from overturning.

Note that, 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 the first aspect of the present invention, a portal-shaped second pipe support capable of freely supporting a pipe so as to overlap the first pipe support space by the first pipe support member. Since a plurality of members are detachably connected to the parent girder part at intervals in the longitudinal direction, when installing another pipe at an interval on the first pipe support space, a conventional method is used. Even if a long rack is not prepared as described above, it is possible to support the another pipe by a plurality of the second pipe support members. And since the said 2nd piping support member itself is detachable with respect to the said main girder part, in the state removed from the main girder part, it is more compact than the conventional long rack, for example, like,
Even in the case of additional piping work in a narrow installation space, it is possible to carry in without installing a new material entrance, and since it is compact, it is easy to handle, and the assembly work can be performed efficiently. It becomes possible. As a result, it is possible to shorten the construction period of piping work and reduce costs.

According to the characteristic configuration of the second aspect of the present invention, in addition to the effect of the first aspect of the invention, the second pipe supporting member can be formed by a portal-type support. Since it is formed on the top portion, and mounting portions detachable to the pair of parent girder portions are separately formed on the two gate-shaped legs, the load of the pipe is applied via the pipe support portion and the mounting portion. As a result, the transmission to the main girder portion can be reliably performed, and the multistage pipe can be more reliably and stably supported. In addition, the mounting interval of the second pipe support member to the parent girder portion can be changed in magnitude according to, for example, the strength of the pipe to be supported, the shape and the number of pipes, and the second pipe support member can be partially changed as necessary. The additional arrangement of the pipe support member and the removal of the unnecessary second pipe support member can be freely selected, so that more efficient and economical pipe support can be achieved.

According to the characteristic configuration of the third aspect of the invention, in addition to the effects of the first or second aspect of the invention, the second pipe supporting member is provided with the second pipe at the leg thereof. Since the support member forms a fall prevention mechanism capable of preventing the fall of the main girder along the longitudinal direction, the fall of the second pipe support member attached to the main girder is determined by the fall. This can be prevented by the prevention mechanism, and more stable pipe support can be achieved. Also,
Even when the main girder portion and the second pipe support member are attached by bolts, the overturn prevention mechanism prevents the second pipe support member from overturning, so that the number of bolts used is minimized (for example, each Even if only one cable is used, mounting can be performed in a state in which the vehicle does not fall down, and it is possible to reduce the time and effort required for mounting and to expect an economic effect by reducing the number of parts used.

According to the fourth aspect of the present invention, in addition to the effects of any one of the first to third aspects of the present invention, the second aspect of the present invention comprises the second aspect of the present invention. The pipe supporting member is formed of sheet metal, and on both side edges of the legs, bent reinforcing portions formed by bending in the spacing direction of the parent girder portions are separately formed, and the edge portions of the bent reinforcing portions are Since the second pipe support member is prevented from tipping over by contacting the upper side of the main girder part, the bending reinforcement part allows the second pipe support member to be prevented from falling even without providing a dedicated configuration for preventing tipping. It is possible to use both reinforcement and fall prevention. Further, since the second pipe supporting member is made of sheet metal, it does not take much trouble to form the bent reinforcing portion, and it can be provided with a simple configuration at a low cost. In addition, it is possible to make the pipe support more stable by increasing the strength by the bending reinforcing portion.
