Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a piping support device used when a conduit or the like is embedded in a concrete floor or panel of a building. (Prior Art) When a concrete floor of a building is made, there is a construction method in which pipes are previously formed for wiring electric wires and are buried in the concrete. FIG. 4 shows a construction method when the pipe 11 is buried inside the concrete 12. First, the floor 13 for casting is supported by a support 14 and is kept horizontal.
On the upper surface of this floor, a pipe 11 for electric wires to be buried inside the concrete 12 is arranged. In the middle of the pipe 11, an electric box 15 for drawing out the electric wire inside the pipe to the outside is also provided. Here, it is better for the pipe 11 to maintain a constant depth inside the concrete 12. Therefore, a support device 16 for supporting the pipe 11 is used. The support devices 16 are arranged at a plurality of locations, and are initially attached to the floor 13 with screws or the like. When arranging the pipe 11, the height of the pipe support is adjusted. The height L2 is important for determining the position of the pipe 11 inside the concrete 12. It is also important to prevent the pipe 11 from meandering up and down. If the pipe 11 meanders, it will be a hindrance to conducting the wiring thereafter. Therefore, the above-mentioned conventional supporting device has a structure as shown in FIG. 5, and has a structure in which the position of the pipe 11 can be adjusted up and down. That is, the bolts 122 are provided on the upper surfaces of the pair of substrates 21a and 21b.
a and 22b are mounted upright. This installation is welding. Next, nuts 24a and 24b are attached to the bolts 22a and 22b, and a support plate 23 is attached to the bolts 22a and 22b. The support plate 23 has holes at both ends through which the bolts 22a and 22b pass. And each hole is nut 24
a, 25a and nuts 24b, 25b. The pipe 11 is placed on the support plate 23 so as to intersect with it.
Is arranged. The pipe 11 can bundle and protect many cables and the like. And this piping 11 is
And the support plate 23. The holding plate 26 and the support plate 23 are tightened by a plurality of screws 27 and hold the pipe 11 (problems to be solved by the invention). According to the pipe support device described above, as shown in FIG. Before casting, they are arranged on the floor 13. At this time, the substrates 21a and 21b use holes or screw holes,
It is fixed on the floor 13 so as to keep a predetermined interval (L1, see FIG. 5). If the distance L1 is shifted, the support plate 23
Adjustment is required when mounting. Therefore, the above substrates 21a and 21b need to be carefully arranged and fixed, which hinders workability. Furthermore, depending on the thickness of concrete, etc.
Height (L2) is adjusted.
This is performed by rotating 24a, 24b, 25a, 25b using a tool. However, this adjustment is very troublesome, and rotating the nuts above and below the support plate 23 is a factor that reduces workability. In addition, since not only the pipes but also the rebar are piped around this area, they may limit the degree of freedom in performing the adjustment work. Further, the above adjustment of the height (L2) may be necessary even during the casting of concrete. This is the fourth
As shown by the broken line in the figure, the weight of the concrete 12 causes the floor 13 to bend in the direction of the arrow, thereby impairing the horizontality of the piping, and this must be corrected. In such a case, the support plate 23 needs to be adjusted in the lifting direction, but the work needs to be performed quickly before the concrete 12 is hardened. However, sufficient adjustment may not be possible due to poor workability as described above. Therefore, the present invention improves the arrangement and mounting workability,
It is another object of the present invention to provide a piping support device capable of quickly adjusting the height. [Constitution of the Invention] (Means for Solving the Problems) The present invention provides first and second bolts attached to the longitudinal ends of a substrate so as to stand up, respectively, and the first and second bolts. First and second nuts respectively attached to bolts and formed with a ring-shaped notch having a small diameter from the outer periphery in the axial direction, and are substantially combined with each other so as to sandwich the notch.
The first and second cutouts of the letter shape are formed at both ends in the longitudinal direction, and the first and second cutouts of the support plate and the nuts respectively engaged with them are not separated. , And first and second stoppers fixed to the support plate and allowed to rotate the nut to be locked to the nut. (Operation) If the height of the support plate (position with respect to the bolt) is to be adjusted by the above-described means, only the nut needs to be rotated upward, and good workability can be obtained. Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. FIG. 1 (a) is an exploded perspective view and FIG. 1 (b) is a view showing an assembled state. As shown in FIG. 1 (a), the substrate 31 of the present apparatus is a single rectangular plate, on which bolts 32a and 32b (32b are not shown) that are vertically erected in the longitudinal direction are attached. I have. In the drawing, the structure provided also at both ends of the substrate 31 is:
Due to the similar symmetric structure, the structure at one end is shown. There are various methods for fixing the bolt 32 and the substrate 31,
For example, welding is performed using the auxiliary nut 32a. A nut 33 is attached to the bolt 32. The nut 33 is complex and is characterized by its shape and function. That is, the nut 33 is formed with a ring-shaped cut portion 33b having a small diameter from the outer periphery in the axial direction, has an upper portion 33a and a lower portion 33c, and for example, the axial length of the lower portion 33c is longer than that of the upper portion 33a. Selected. Next, the shape of the support plate 34 is formed as follows.
That is, a substantially U-shaped cutout portion 35 that is combined so as to sandwich the cutout portion 33b of the nut 33 is formed at the longitudinal end. When the notch 35 is engaged with the notch 33b of the nut 33, movement in the axial direction with respect to the nut 33 is restricted, but rotation is free. FIG. 4B shows a state in which the notch 35 is engaged with the notch 33 b of the nut 33. Next, a stopper 36 is used to prevent the engaged state from being released. The stopper 36 has a hole 36a through which the nut 33 can pass, and a screw hole 36 for integrating with the support plate 34.
b is formed. The screw holes 36b correspond to the screw holes 34b of the support plate 34, and when they are integrated, they are fastened and fixed by screws 37 as shown in FIG. As a result, the support plate 34 does not separate from the bolt 32. FIG. 1 shows one structure, but the other has a similar structure. On the support plate 34, pipes are arranged crossing in the same manner as in the prior art, and this pipe is fixed on the support plate by a holding plate as shown in FIG. According to the support device configured as described above, for example, as shown in FIG.
By rotating the nut 33 with a tool having the nut engaging portion 41, only the nut 33 rotates, and the height (L2) of the support plate 34 can be freely and easily adjusted.
Further, since the work can be performed by inserting the tool 40 into the lower part of the support plate 34, the adjusting work is easy and quick even in a narrow space. Further, the notches at both ends of the support plate 34 are engaged with a pair of bolts. In this case, the distance between the bolts is precisely defined by the substrate 31, so that The intervals do not become irregular, and there is no need for unnecessary adjustment work as in the related art. The present invention is not limited to the above embodiment, and the first and second cutouts of the support plate and the nuts respectively engaged with the first cutouts are fixed to the support plate so that the nuts do not come off. 2 and 3 may be used as the stopper that allows the nut to rotate and lock the nut. That is, a notch is formed around the notch 35 of the support plate 34 to form a cut-and-raised piece 341, and the cut-and-raised piece 341 is bent as shown in FIG. It may be locked to 33b. Further, as shown in FIG. 3, a slit 342 of a through hole is formed around the notch 35 of the support plate 34, as can be seen from the figure, and this slit 342 is pushed open toward the U-shaped opening side of the notch 35. Thereby, a locking portion which is a deformed portion may be formed and locked to the cut portion 33b of the nut 33. [Effects of the Invention] As described above, the present invention can provide a piping support device that can improve the arrangement and mounting workability and can quickly adjust the height.
