Description

[Detailed description of the invention] This invention relates to a pipe fixing device on a pipe shelf, in which both ends of a plurality of pipes arranged in parallel at appropriate intervals are held from above and below by a support bar and an insert, and the pipes are tightened and fixed using screws. In a pipe shelf consisting of a pipe rack, the pipe spacing is maintained and fixed securely to eliminate misalignment and twisting between the clamping and fixing members, and at the shelf side end, tightening is performed by tightening the screws on the protruding parts of the screws and the outer surface of the clamping members. It was devised for the purpose of forming such a flat surface without creating an uneven surface.

Conventionally, the pipe fixing part of this type of pipe shelf was to attach corrugated or U-shaped inserts from the pipes arranged in parallel on the Heian crosspiece and tighten them with screws and nuts. When this is done, the heads and tips of the screws protrude to the outside of the upper and lower crosspieces, and the insertion core forms an uneven surface, so there are many unevenness and protrusions on the top and bottom of the shelf side edge, which is unsightly and has dirt on the four parts. It is filthy as it tends to get stuck and build up, and if the insert is made of a corrugated plate, the pipe is not securely fastened enough and the pipe tends to slip off.

Therefore, in order to eliminate the above-mentioned drawbacks, the present invention improves the shape, structure, and tightening method of the insertion core and holder.An example of the invention will be explained with reference to the drawings.In the figure, 1 is a pipe, and 2 is a holder. , 3 is an insert, 4 is a hanging frame, and the pipe 1 has a cap 5 attached to its end.

The receiving crosspiece 2 is made by bending both ends of a band-shaped flat plate upward, and drilling a locking hole 7 in the horizontal inner side of the bent part 6.
Three protrusions 8 are pushed out from the bottom surface between the pipes in the middle, and screw holes 8' are provided therein.

The insertion core 3 has a U-shaped cross section, and has notches 10 for inserting parallel pipe ends arranged in rows along both side edges 9°9 of the opening corresponding to the pipe spacing, and a recessed through hole 12 in the upper end 11. The hole edge is recessed from the upper surface and is bored in correspondence with the screw hole of the receiving crosspiece.

The suspension frame 4 is made by bending a flat band-like plate into a rectangular shape, and has a front and rear width that allows the receiving bar 2 to fit therein.Latching claws 14, 14 are provided oppositely on the front and rear ends of the bottom piece 13 of the frame body, and the locking claws 14, 14 are provided oppositely at the front and rear ends of the bottom piece 13. The locking holes 7 at both ends of the receiving bar are adapted to engage with the claws.

Note that 15 is a tightening screw.

Each member of the pipe shelf in the present invention has the above-mentioned configuration,
A core is mounted on each end of the pipes arranged in parallel on the support bar, and screws 15 are respectively inserted from the top of the core through the recessed through hole 12 toward the threaded hole 8' on the support bar and tightened. The pipes are clamped and crimped with the clamps, and the pipe shelf made of the parallel pipes fixed at appropriate intervals is fitted into the hanging frame 4, and the locking hole 7 of the receiving frame is inserted into the hanging frame bottom piece. A hanging shelf is constructed by engaging with the locking claws 14 of.

The present invention is constructed as described above, and the shape of the insertion core is U-shaped in cross section, and notches 10 are arranged in rows on both sides of the opening, and after inserting the pipe end into the notch, the insertion core and the upper surface of the receiving bar are connected. Since the pipes are tightened and compressed with screws, the fixation of the pipes and the maintenance of their spacing are reliable and firm, and each member does not shift or twist at the fixing part, making it possible to construct a sturdy shelf. The upper surface of the insertion core is flat, and the head of the screw is recessed into the edge of the recessed hole so that it is flush with the upper surface of the insertion core, and the screw hole is provided in the raised part of the support bar. As a result, the lower end of the tightened screw does not protrude downward from the bottom of the support frame and is accommodated within the support frame.The upper and lower surfaces of the shelf end are both flat, and there are no protrusions, making it easier to handle the shelf. It is safe, the shelf has a good appearance, and since there are no hooks, the shelf is easy to wipe clean, and there is little dirt and grime attached, so it is hygienic.
