Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a support device for raising flexible pipes.
Mainly during building construction, highly flexible electrical conduits buried in floor slabs and other surfaces are temporarily supported in an upright position on the slab to prevent them from collapsing when concrete is poured, especially when they are set up. This invention relates to a support device for raising a flexible tube that can reliably prevent it from collapsing in any direction.

[Technical background of the idea and its problems] Traditionally, when constructing a concrete building, when various types of wiring were to be carried out on a concrete slab, conduits were raised up on the slab and temporarily supported. The timber is poured and buried and fixed. As shown in, for example, Japanese Utility Model Application Publication No. 102880/1983, a device used when starting up this conduit has a flat part for floor mounting and a sleeve for supporting the base of the rising pipe. A device was used consisting of a fixture and a protective tube that was removably attached to the upper end of the sleeve. Also, Utsukai Showa 51-
As shown in Japanese Patent No. 65300, there were also cables in which the cable was supported by a band-shaped body and tied with a binding wire.

However, in the device shown in Japanese Utility Model Application Publication No. 56-102880, the fixture with the sleeve is formed of a substantially U-shaped flat plate, so it cannot be used for piping set up by pouring concrete material. When a large lateral pressure is applied, the fixture deforms and the piping supported by the sleeve of the fixture and the protection tube collapses. Also,
In the device shown in Japanese Utility Model Application Publication No. 51-65300, a binding wire is hooked onto the engagement protrusion of the band-shaped body, and the two binding lines are wound around the band-shaped body and the cable so as to cross each other. , the winding work was very troublesome.

[Purpose of the invention] Therefore, this invention was devised in view of the points mentioned above, and is a method for temporarily supporting electrical conduits with many flexible pipes buried in floor slabs or other surfaces in an upright manner on the slab. Another object of the present invention is to provide a support device for raising a flexible pipe that can reliably prevent the collapse of concrete material during pouring, especially the collapse in any direction when the concrete is stood up.

[Summary of the invention] In order to achieve the above-mentioned purpose, this invention includes a support device for raising a flexible tube, a base body having a reinforcing beam piece and capable of being fixed to the surface of a temporary frame panel, and a cylindrical base body. A stand member forming a standing leg connection part with a plurality of adjustment protrusions raised along the depth direction on its inner peripheral surface, and a rod of an appropriate diameter that is removably fitted into the upright leg connection part and supported in the form of a standing leg. It was decided to consist of a bar member made of wood, and a tying wire member for tying the flexible pipe to be erected and supported on a concrete slab to the bar member.

[Embodiments of the invention] Hereinafter, embodiments of the invention will be described with reference to the drawings.

The symbol P shown in the figure is a flexible pipe that is buried in a concrete slab F such as a floor slab constructed in building construction work, and whose tip portion is supported in an upright manner on the concrete slab F.
For example, it is a flexible electrical conduit made of synthetic resin, a spiral band, or even a double pipe structure if necessary, and this devised device has come to be set outside of this flexible pipe P. ing.

On the other hand, S is slab reinforcement arranged in a grid or other form within the concrete slab F, and steel rods of an appropriate diameter are used, and W is a wooden temporary frame panel.

In order to support the flexible pipe P that is to be buried in an upright manner on the concrete slab F, there is a stand member 1 fixed to the surface of the temporary frame panel W, and a stand member 1 that is erected and can be detachably attached. A bar member 11 to be supported and a tying wire material 15 for tying and supporting the flexible tube P to the bar member 11 are used.

The stand member 1 is made of synthetic resin and usually has a height of about 40 mm, and has a cylindrical stand connection part 9 formed on a base body 2 that can be fixed to the surface of the temporary frame panel W. . Specifically, Figures 1 to 3
As shown in the figure, nail holes 5 are drilled on both sides of the opening of the main body 3, which has a generally groove-shaped cross section and is open at the bottom, through which temporary fixing nails B to be driven into the surface of the temporary frame panel W are inserted. By providing the fastening pieces 4 with wings, the base body 2 has a generally hat-shaped overall cross section, and a bottomed cylindrical standing leg connecting part 9 is formed through the center of the top wall of the main body 3, and the standing leg A reinforcing beam piece 6A is continuously provided between the outer periphery of the connecting portion 9 and the left and right wall portions of the main body 3.
By doing so, the main body 3 and the pedestal connecting portion 9 do not become separated from each other, and in particular, the left and right side walls of the main body 3 do not become distorted, and the pressure of the concrete material to be poured is prevented. It can withstand shock and other impacts sufficiently, and when removing the temporary frame panel W, the main body 3
Since the top wall portion of the stand member 1 is integrated with the slab F, it is possible to prevent the stand member 1 itself from coming off.

In addition, as shown in FIG. 5, triangular reinforcing ribs 6C may be provided protruding from the outer surface between the fastening piece 4 and the left and right walls of the main body 3 in order to reinforce the fastening piece 4. Furthermore, in order to reinforce the top wall portion of the main body 3, the top wall portion and the standing leg connecting portion 9 are installed inside the main body 3.
It is also good to make the reinforcing beam pieces 6B protrude continuously from each of them.

Further, as shown in FIG. 6, a cylindrical erected leg connecting part 9 is erected in the center of the disc-shaped base body 2 with nail holes 5 drilled in the peripheral edge, and around the erected leg connecting part 9, for example. A triangular reinforcing wing 7 is installed in a state where it is continuous with the base body 2, and a substantially triangular cutout whose width gradually becomes wider as it reaches upward is provided, either continuous with the reinforcing wing 7 or not. It may also be provided with escape prevention blades 8. According to this, the reinforced wing 7
This ensures reliable integration of the base body 2 and the upright connecting part 9, and at the same time prevents deformation. Also, when removing the temporary frame panel W, the removal prevention wing 8 prevents the slab F.
By being integrated with the stand member 1, it is possible to prevent the stand member 1 itself from being removed.

The illustrated standing leg connecting portion 9 has a plurality of adjustment protrusions 10 raised along the depth direction on its inner circumferential surface, and the adjusting protrusions 10 are fitted into the upstanding leg connecting portion 9. Even if there is a slight error in the diameter of the bar member 11, it is useful to prevent rattling, thereby ensuring that the bar member 11 is maintained in a standing state.

Further, the nail hole 5 has a substantially T-shape in plan view, including a direct portion 5A formed in the form of a long hole, and a nail accommodating portion 5B perpendicular to the direct portion 5A in which the nail B pillar portion is accommodated. Because of this, the nail B is attached to the temporary frame panel W.
By placing the nail B in the nail accommodating portion 5B when driving the nail B, after the temporary frame panel W is demolded, the head of the nail B is locked to the area on the second side of the base body around the nail hole 5. Although the nail is left behind, it can be removed from the nail hole 5 by holding the tip of the nail B with a tool such as pliers or pliers and forcibly tilting the nail B so that its head is positioned in the connecting part 5A, and various subsequent operations can be done. Safety can be ensured during implementation.

The bar member 11 that is detachably supported in the form of a standing leg of the stand member 1 is preferably formed of a rod material of an appropriate diameter that is forcefully fitted into the standing leg connecting portion 9 of the stand member 1. Ru. The illustrated bar member 11 consists of a straight raised part 12 that is longer than the thickness of the concrete slab F, and a horizontal engagement part 13 that is bent and extended horizontally from the upper end of this raised part 12. It is formed in an L-shape, and after the flexible tube P is buried and supported in the slab F in an upright state, it is appropriately engaged with the horizontal engaging portion 13 and moved upward. It is designed to be convenient for forced removal.

Further, the tying wire material 15 for tying and supporting the flexible tube P to the bar member 11 is formed of a wire material such as a string or wire of an appropriate diameter, and is flexibly placed on the slab F as shown in FIG. Whether the pipe P is tied to the bar member 11 or within the slab F (not shown) can be arbitrarily set depending on the situation at the site.

This device is constructed as described above. Next, to explain its use, a base is placed on the surface of the framed temporary frame panel W at a position where a flexible pipe P such as a conduit pipe is to be launched according to a predetermined design. At the same time, the stand member 1 is fixedly set on the body 2, and the bar member 11 is fitted into the stand leg connecting portion 9 in a stand-up shape, and the flexible tube P is bent into a stand-up shape. The portion is placed along the bar member 11 and is tied and supported integrally with a tie and tie material 15.
Next, as shown in Figure 2, concrete material is poured and solidified to form a concrete slab F.
Thereafter, the binding wire material 15 is removed, and only the bar member 11 is removed by appropriate means, as shown in FIG. In addition, it is preferable to cover the opening of the flexible pipe P with a cap C to prevent the concrete material from entering into the flexible pipe P during pouring of the concrete material.

[Effect of the invention] Therefore, the flexible pipe P that should be stood up and supported is
Although the flexible tube P is maintained upright by the bar member 11 fitted and supported on the temporary frame panel W via the stand member 1 in the form of a standing leg, and is supported from the outside of the flexible tube P, the flexible tube The binding wire 15 prevents the flexible tube P from falling down by integrally connecting the flexible tube P to the bar member 11, and prevents the rectification of the flexible tube P into a straight line. endure,
The startup state can be maintained reliably.

The stand member 1 itself has reinforcing beam pieces 6A and 6B and has a base body 2 that can be fixed on the surface of the temporary frame panel W.
In addition, since the upright connecting part 9 is formed in a cylindrical shape and has a plurality of adjustment protrusions 10 raised along the depth direction on its inner circumferential surface, it can be firmly fixed and set on the surface of the temporary frame panel W. Therefore, the stance leg connection part 9
The bar member 11 fitted and erected on the bar member 11 and the flexible pipe P tied to the bar member 11 may collapse or separate from the temporary frame panel W due to pressure, impact, etc. of the concrete member generated during pouring. Therefore, these 11,P can be supported in a stable state. Of course,
Since the base body itself also has the reinforcing beam pieces 6A and 6B, it will not deform even if large pressure is applied from the front, back, left, and right sides during concrete pouring, and the flexible tube P can be attached to the bar member 11. You can keep it up and running steadily.

Further, the bar member 11 is removably fitted into the upright leg connecting portion 9 of the stand member 1 and is supported in the form of an upright leg, but the upstanding leg connecting portion 9 itself is cylindrical as described above and has a depth direction on its inner circumferential surface. Since the plurality of adjustment protrusions 10 are raised along the ridges, when the one end bar member 11 is fitted to the upright leg connecting portion 9 of the stand member 1,
The bar member 11 does not easily come off from the erected leg connecting portion 9, and the flexible tube P can be firmly raised by the bar member 11.

Furthermore, since the stand member 1 can be formed into a small size, it can be made to be about the same size as a normal insert tool T buried in the slab F, and it can be fixed before the reinforcement of the slab reinforcement S. Even if it is left embedded as it is, it does not get in the way, and the stand member 1 can be fixedly set on the temporary frame panel W after removing the smudges before arranging the slab reinforcements. Coupled with the fact that there is no need to put on clothes, it is also possible to shorten the working time.

As explained above, according to this invention, flexible pipes such as electrical conduit pipes buried in floor slabs or other surfaces are temporarily supported in an upright manner on the slab, and are prevented from falling down when concrete material is poured. can be prevented,
In addition, when temporarily supporting the stand member, it is possible to fix the stand member to the temporary frame panel surface, fit and connect the bar member to the stand member in a erected form, and tie the flexible tube to the bar member with a tie wire material. Any work such as support can be done easily and without any trouble, so the work can be completed quickly.Also, after use, the bar member can be removed and reused, which is convenient, and the structure is simple. This has practical effects such as being able to be provided at low cost.
