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. The present invention relates to a support device for raising flexible tubes that can reliably prevent collapse in any direction and also helps save resources by using members that can be used repeatedly.

[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. Fixtures and
A device consisting of a removable protective tube attached to the upper end of the sleeve was used.

However, in the device shown in Japanese Utility Model Application Publication No. 56-102880, after fixing the hole provided in the flat part to the floor surface with bolts, each protective tube is inserted into the rising part of each piping. Since the device was screwed into the sleeve, the installation work was extremely troublesome. In addition, when many pipes are installed in close proximity, square box-shaped sleeves and protection pipes must be installed, and the shapes of the sleeves and protection pipes must be made different depending on the number of pipes. However, the manufacturing of the entire device becomes complicated and the manufacturing cost tends to increase.

[Purpose of the invention] Therefore, this invention was devised in view of the points mentioned above, and is mainly used during building construction to raise highly flexible electrical conduits buried in floor slabs or other surfaces onto the slab. By temporarily supporting the concrete, it reliably prevents it from falling down during concrete placement, especially when it is set up, and also prevents it from falling down in any direction.
The object of the present invention is to provide a support device for standing up flexible tubes that has a simple configuration and is capable of supporting a plurality of flexible tubes.

[Summary of the invention] In order to achieve the above-mentioned purpose, this invention is a flexible tube that is bent into a mountain shape so as to come into contact with the outer periphery of a flexible tube that is to be supported upright on a concrete slab, and which is also bent into a planar wave shape. A support part that can support multiple flexible tubes is formed, and the standing legs are bent and suspended from both ends of this support part, so that the entire support part and the standing legs are made into one piece with an appropriate diameter. a stand member integrally formed by bending a rod; and a stand member having a stand tube that is provided with means for attaching to a temporary frame panel or slab reinforcement and that supports the stand leg in a detachable manner. This structure ensures that the concrete does not fall down even when concrete material is being poured, and that the standing condition is maintained, and in particular, that it does not fall down in any direction when it is set up. At the same time, even though some of the members remain buried, they do not become a hindrance, and the structure is extremely simple and can be provided at low cost without increasing the economic burden.

[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 invented device is set outside the flexible pipe P. It's summery.

On the other hand, S is a slab reinforcement arranged in a lattice 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.

Therefore, in order to support the flexible pipe P to be buried in the concrete slab F in an upright manner, stand members 4 and 9 are fixed to the temporary frame panel W or the slab reinforcement S and remain buried in the concrete slab F. A standing member 1 is used which is detachably supported by the stand members 4 and 9 in the form of a standing leg to stand up the flexible tube P, and which is removed after being buried and supported and can be reused. Ru.

The rising member 1 has a support part 2 bent in a chevron shape that contacts the outer periphery of the flexible pipe P that is to be supported in a raised shape on a concrete slab F, and a support part 2 that is bent in a chevron shape and extends from both ends of the support part 2. The supporting portion 2 and the leg portions 3 for standing up are integrally formed by bending a rod having an appropriate diameter. The support part 2 itself has one or more recesses along the outer diameter of the flexible tube P so that it can be made into contact with the outer periphery of the flexible tube P, and the flexible tube P can be specially stored and set in the recesses. The recess itself is bent into a substantially U-shape or V-shape in plan view to be suitable for supporting one flexible tube P. The support part 2 shown in the figure is bent into a planar waveform so that it can support a plurality of flexible tubes P, and each recess into which the flexible tubes P are directly stored and set is as shown in the figure. Of course, the shape is not limited to a flat, substantially V-shape. In addition, when supporting multiple flexible tubes P at the same time, it is convenient to make the mutual spacing correspond to the mutual spacing between the knockout holes in wiring boxes such as outlet boxes, and usually 44 mm. Ru.

Further, the standing leg part 3 connects the standing member 1 itself to the stand members 4 and 9 by being removably fitted to the stand members 4 and 9, and when supporting the connected standing legs. The support portion 2 is formed to be longer than the thickness of the concrete slab F so as to be sufficient to allow the support portion 2 to protrude above the concrete slab F in the above.

On the other hand, the stand members 4, 9 are provided with attachment means 7, 8, 12 to the temporary frame panel W or the slab reinforcement S, and have stand tubes 6, 11 that support the standing legs 3 in a detachable manner. It is a thing.
The stand members 4 and 9 themselves are used in correspondence with each of the standing legs 3, and are usually used as a pair on the left and right and buried in the concrete slab F to be constructed. Standing member 1 and flexible pipe P at the time of pouring concrete material
It is sufficient if it is fixed to either the temporary frame panel W or the slab reinforcement S so as to firmly support the structure. Incidentally, the standing leg cylinders 6 and 11 are made of plastic, iron, or the like, and have an inner diameter corresponding to the outer diameter of the standing leg 3 so that the standing leg 3 is fitted, preferably forcibly fitted. It is formed into a cylindrical shape.

Stand member 4 according to Figures 1 and 2
is cast and fixed via a fixing device 7 such as a U-shaped staple while in contact with the surface of the temporary frame panel W, or a string, wire rod or other binding wire material 8 is placed along the slab striations S. A stand tube 6 is formed upright on a fixing rod 5 made of rod material, which is tied and fixed via a rod. The fixing rod 5 itself is made of a rod material with a predetermined diameter, and as shown in the figure, it is L-shaped in plan to prevent rattling when it comes into contact with the surface of the temporary frame panel W. Bend the connecting part of the side L so that it stands upright.
It is shaped like a letter. At this time, as shown in Fig. 1, when fixing to the surface of the temporary frame panel W, there is a force that causes the flexible tube P that is forcibly bent for erection to return to the original straight line, and the concrete material to be poured It is extremely preferable that the directions in which the fixing rods 5 contact the surface of the temporary frame panel W are made different on the right and left sides of the standing leg portions 3 so that the temporary frame panel W can be supported without wobbling due to pressure, impact, or the like. Further, as shown in FIG. 2, when fixing to the slab reinforcement S, the stand member 4 itself is arranged so that its fixing rod 5 extends in the opposite direction from the piping side of the flexible pipe P. As a result, when the flexible tube P, which has been bent by standing upright, tries to straighten to restore its current state, the fixed rod 5 firmly supports it at the side where the load is applied. , which helps prevent collapse and further increase installation stability.

The stand member 9 shown in FIG. 3 has a base member 11 in the form of a plate, which is driven and fixed on the surface of the temporary frame panel W, and a stand tube 11 erected thereon.
An appropriate number of penetration fixing holes 13 into which nails 12 are inserted are drilled in the base body 10 which has a circular or other appropriate shape. According to this stand member 9, by being attached to the surface of the temporary frame panel W, the stand-up member 1,
Of course, it is possible to support the flexible tube P, but it also has the advantage that the stand member 9 can be removed from below after demolding the temporary frame panel W, and that it can be reused.

In the figure, 20 is a cap that closes and closes the opening of the flexible tube P, and 21 is a stand-up retainer made of rod material that is inserted into the flexible tube P and maintains the bent state in the upright shape. It is a rod.

This device is constructed as described above, and its use will now be explained. According to a predetermined design, a flexible pipe P such as a conduit pipe should be erected as shown in FIGS. 1 to 3. At the position, either of the stand members 4, 9 is attached to the temporary frame panel W, the slab strip S, via the attachment means 7, 8, 12 to the temporary frame panel W,
S, the standing member 1 is supported by the stand members 4 and 9 using the standing leg part 3, and the upright part of the flexible tube P bent in the standing shape is It is stored in the recess of the support part 2, tied appropriately in the support part 2 if necessary, and then concrete material is poured, cured for a suitable period of time, and solidified to form a concrete slab F. At this time, if necessary, insert the L-shaped lifting maintenance rod 21 from the opening of the flexible tube P, and
0 to the opening of the flexible tube P, the flexible tube P itself is reliably maintained upright, and entry into the flexible tube 4 is reliably prevented. Next, after the concrete material has solidified, as shown in FIG. 4, only the standing member 1 is removed from the concrete slab F, and a predetermined wiring box (not shown) is connected to the flexible pipe P, and the wiring is connected to the flexible pipe P. The work shall be carried out.

[Effect of the invention] Therefore, the flexible tube P to be stood up is stored and supported within the recess of the support part 2 of the standing member 1 supported by the standing legs via the stand members 4 and 9. Although the flexible tube P is supported from the outside, the inner part of the support part 2 supports the restoring force of the flexible tube P in a straight line and prevents it from falling down. Since both sides of the recess in the support part 2 support it in the left-right direction, it can withstand external force from any direction and maintain the standing state reliably.

Since the support part 2 itself is bent into a mountain shape with the flexible tube P in contact with the outer periphery, the flexible tube P is supported in each of the concave portions of the mountain shape. Moreover, it can be supported without inferiority even if it is bent in the shape of a mountain, and it can be supported by the both sides of the recess obtained by bending in the shape of a mountain. The difficult task of maintaining an upright position can be made more perfect. Since the support part 2 itself can support a plurality of flexible tubes P by bending into a plane waveform, it can support a plurality of flexible tubes P in parallel as shown in the figure, and can also support a plurality of flexible tubes P in the front and rear directions. By making it symmetrical, it is possible to simultaneously support a plurality of flexible tubes P from both opposite directions (not shown). In addition, the support portion 2 bent into a planar waveform
With the upright member 1 having the above structure, it is possible to support not only one flexible tube P but also a plurality of flexible tubes P with one device, and it is possible to support the upright member 1 according to the number of flexible tubes P to be supported. There is no need to make the shape of the raising member 1 different. Therefore, by bending the support portion 2 of the erecting member 1 into a plane waveform, a plurality of flexible tubes P can be formed.
Furthermore, the structure can be simplified, a large number of devices can be manufactured in a short time, and the manufacturing cost of the device can be reduced.

The standing leg parts 3 bent and suspended from both ends of the support part 2 serve as a direct support device for the bending part of the flexible tube P, and hold the support part 2 at an appropriate height. Standing tubes 6, 1 of stand members 4, 9
1, it is extremely easy to connect to the stand members 4 and 9 during temporary fixing and to remove after embedding support.

Attachment means 7, 8, 12 to the temporary frame panel W or slab reinforcement S provided on the stand members 4, 9
Not only is it extremely convenient because it allows for diversification of mounting modes and allows you to choose between mounting to the temporary frame panel W or slab reinforcement S depending on the situation at the site, but also allows the mounting work to be carried out easily and efficiently. It is possible.

Furthermore, since the entire raising member 1 consisting of the support part 2 and the raising legs 3 is integrally formed by bending a single rod of an appropriate diameter, it can be constructed at an extremely low cost, and can be constructed using only temporary frame panels. Even if concrete is poured and buried while attached to W or slab reinforcement S, after it solidifies, it can be removed by forcibly removing it from the concrete slab F, making it reusable. There is no waste, and it greatly contributes to resource conservation.
