Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) This invention relates to a pipe support device used when embedding electrical conduit or the like in a concrete floor or panel of a building.

(Prior Art) When constructing a concrete floor for a building, there is a method in which piping is installed in advance for wiring electric wires and the piping is buried inside the concrete. FIG. 4 shows a construction method for burying the pipe 11 inside the concrete 12. First, the pouring floor 13 is supported horizontally by a support 14. On the upper surface of this floor, piping 11 for electric wires to be buried inside concrete 12 is arranged. Piping 11
An electric box 15 is also provided in the middle of the tube for pulling out the electric wires inside the tube to the outside. 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 multiple locations and are initially attached to the floor 13 with screws or the like. Then, when arranging the piping 11, the height of the piping support is adjusted. This height L2 is important in 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 piping 11 winds, it will become a hindrance to the subsequent wiring.

Therefore, the conventional support device described above has a structure as shown in FIG. 5, which allows the position of the pipe 11 to be adjusted up and down. That is, bolts 22a and 22b are installed in an upright manner on the upper surfaces of the pair of substrates 21a121b. This installation is welded.

Next, nuts 24a124b are attached to the bolts 22a and 22b.
is attached, and furthermore, a support plate 23 is attached by spanning the bolts 22a and 22b. The support plate 23 has bolts 22a
, 22b have holes at both ends thereof. The respective holes are provided with nuts 24ab 25a, nuts 24b, 2
5b.

The piping 1 is placed on top of the above support plate 23 so as to intersect with this.
1 is placed. The piping 11 can bundle and protect a large number of cables. The pipe 11 is held between the presser plate 26 and the support plate 23. The holding plate 26 and the support plate 23 are tightened by a plurality of screws 27 to hold the pipe 1. (Problem to be Solved by the Invention) According to the pipe support device described above, as shown in FIG. ,
Before pouring concrete, they are arranged on the floor 13. At this time, the substrates 21a and 21b are fixed on the floor 13 using holes or screw holes so as to maintain a predetermined distance (Ll, see FIG. 5). If there is a deviation in this interval L1, adjustment will be required when attaching the support plate 23 later.

Therefore, it is necessary to be careful in arranging and fixing the substrates 21a and 21b, which poses a problem in workability.

Furthermore, depending on the thickness of the concrete, etc., the support plate 23
The height L2) of the nut 24 a s 24 b s 25 a s 25 b is adjusted.
This is done by rotating the machine using a tool.

However, this adjustment is extremely troublesome, and rotating the nuts located above and below the support plate 23 is a factor that reduces work efficiency. Furthermore, since not only piping but also reinforcing bars and the like are arranged around this area, these may limit the degree of freedom in performing adjustment work.

Furthermore, the above-mentioned height L2) adjustment may be required even during concrete pouring. This is the fourth
This is because, as shown by the broken line in the figure, the floor 13 bends in the direction of the arrow due to the weight of the concrete 12, impairing the horizontality of the piping, and this needs to be corrected. In such a case, it is necessary to adjust the support plate 23 in the direction of lifting it, but this work must be done quickly before the concrete 12 hardens. However, as mentioned above, sufficient adjustment may not be possible due to poor workability.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a piping support device that improves workability in arrangement and installation, and allows quick height adjustment.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes first and second bolts that are respectively attached to vertical ends of a substrate so as to stand upright, and A first nut and a second nut are respectively attached to the bolt and have a ring-shaped notch with a small diameter formed from the outer periphery midway in the axial direction, and a substantially U-shaped first nut is assembled to sandwich the notch. , a support plate having second notches formed at both ends in the longitudinal direction; and a support plate configured to prevent the respective first and second notches of the support plate from separating from the nuts respectively engaged with the first and second notches. and first and second fasteners that are fixed to the nut and lock the nut while allowing rotation of the nut.

(Function) With the above means, if the height of the support plate and the position relative to the bolt are to be adjusted, the nut only needs to be rotated in the upward direction, and good workability can be obtained.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, with FIG. 1(a) being an exploded perspective view and FIG. 1(b) showing an assembled state.

As shown in FIG. 1(a), the board 31 of this device is a single rectangular plate, and bolts 32a and 32b (32b not shown) are attached vertically in the longitudinal direction. There is. In the drawing, since the structures provided at both ends of the substrate 31 are similar and symmetrical, the structure at one end is shown.

There are various methods of fixing the bolts 32 and the substrate 31, but for example, they may be welded using an auxiliary nut 32a. A nut 33 is attached to the bolt 32. This nut 33
is complex and distinctive in its form and function. That is, this nut 33 has a ring-shaped notch 33b with a small diameter formed from the outer periphery in the middle in the axial direction, and has an upper part 33a and a lower part 33c, and for example, the axial length of the lower part 33c is longer than that of the upper part 33a. Selected.

Next, the shape of the support plate 34 is formed as follows.

That is, a substantially U-shaped notch 35 is formed at the longitudinal end portion of the nut 33 so that the notch 33b of the nut 33 is sandwiched therebetween. When this 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. Same figure (b)
3 shows a state in which the notch 35 is engaged with the notch 33b of the nut 33. Next, a stopper 36 is used to prevent this engaged state from becoming a disengaged state.

The stopper 36 has a hole 36a through which the nut 33 can pass.
A screw hole 36b for integration with the support plate 34 is also formed. This screw hole 36b corresponds to the screw hole 34b of the support plate 34, and when the two are integrated, they are tightened and fixed by screws 37 as shown in FIG. 3(b).

Thereby, the support plate 34 will not separate from the bolt 32. Although FIG. 1 shows one structure, the other is of similar structure.

Incidentally, on the support plate 34, pipes are arranged to intersect with each other as in the conventional case, and these pipes are further fixed on the support plate by a holding plate as shown in FIG.

According to the support device configured as described above, for example, the first
A tool 40, that is, a handle part 4 as shown in FIG.
1 and a tool having a nut engaging portion 42, the nut 3 is
3 rotates, only the nut 33 rotates, and the support plate 3
4) can be freely and easily adjusted. Further, since the tool 40 can be inserted into the lower part of the support plate 34, the adjustment work can be performed easily and quickly even in a narrow space. Furthermore, the notches at both ends of the support plate 34 are engaged with the pair of bolts, but in this case, the distance between the bolts is precisely defined by the board 31, so the distance between the bolts is The spacing does not become irregular, and there is no need for unnecessary adjustment work as in the past.

The present invention is not limited to the above-mentioned embodiments, and the first and second notches of the support plate and the nuts respectively engaged therewith are fixed to the support plate so that they do not come off. The stop that locks onto the nut while allowing rotation of the nut may have a structure as shown in FIGS. 2 and 3.

That is, a notch is formed near the notch 35 of the support plate 34 to provide a cut-and-raised piece 341, and this cut-and-raised piece 34
1 may be bent and engaged with the nut 33 as shown in FIG. 3(b).

Further, as shown in FIG. 3, a slot 342 is formed near the notch 35 of the support plate 34, and by pushing this slot 342 open, a locking portion 11 is formed and the nut 33 is locked. Also good.
