Description

[Detailed description of the invention] This invention relates to a support device for raising flexible pipes.
Mainly during building construction work, 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 the tube from falling to the left or right.

Traditionally, when performing various types of wiring on concrete slabs during concrete building construction work,
Electrical conduits are raised up on the slab and temporarily supported, concrete material is placed, and the conduit is buried and fixed. However, since the electric conduit in the standing state is open, it is necessary to appropriately close it. On the other hand, when supporting conduit pipes to be buried in an upright manner, there is no problem in supporting them if they are made of rigid steel pipes, but it is important to make sure that the conduit pipes can be aligned with wiring equipment such as outlet boxes. In the case of flexible synthetic resin pipes and spiral band metal pipes, it is difficult to maintain an upright support state due to their flexibility.

Therefore, this idea was devised in view of the points mentioned above, and its gist is that the supporting back wall that comes into contact with the outer periphery of the flexible pipe that is to be stood up on a concrete slab and supported, and The left and right walls that face the wall continuously are bent into a planar groove shape that is open at the front, and the lower ends of the left and right walls are bent with fastening pieces to be fixed to the temporary frame panel surface. It consists of an extending support body, and fixed maintenance rods that are mounted on the mounting parts provided on the upper left and right walls, located inside the bent part of the bent and raised flexible tube. As a result, even if the concrete material is placed, it will not collapse and will maintain its standing condition. In particular, it will surely prevent the concrete from collapsing to the left and right sides when it is set up, and it will also be able to be buried as it is. Even if it is left behind, it does not get in the way, and it has an extremely simple configuration and can be provided at low cost without increasing the economic burden.

Hereinafter, embodiments of this 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 conduit made of synthetic resin, a spiral band, or even a double pipe structure if necessary, and this invented device is installed outside the flexible tube P. It's summery.

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

Therefore, the front side is formed by the support back wall 2 that contacts the outer periphery of the flexible pipe P that is to be supported in an upright manner on the concrete slab F, and the left and right walls 3 that continuously face this support back wall 2. A support body 1 is formed by being bent into an open planar substantially groove shape and having fixing pieces 6 bent and extended at the lower ends of the left and right walls 3 to be fixed to the surface of the temporary frame panel W. This support 1 is obtained by appropriately cutting and bending a thick sheet material,
Since two types of flexible tubes P with different diameters are usually used depending on the wiring capacity, the inner diameter size is such that at least the large diameter flexible tube P can be accommodated. Also, since this support 1 has a front opening structure, the width of the front opening is made slightly wider than the width of the support back wall 2, as shown in FIG. 6, so that other supports 1 can be overlapped. This makes it convenient for packaging, transportation, and storage.

The supporting back wall 2 is curved or bent in an arc shape, V-shape, etc. so as to be in contact with the accommodated flexible tube P, and its upper end edge is slightly bent outward so that the flexible tube P To prevent damage to the outer peripheral surface. 4 is a concrete material entry hole made in the lower part of the supporting back wall 2, and is a bent part of the flexible pipe P that is bent in a bent shape when concrete material is poured after being fixed to the temporary frame panel P surface. The purpose is to make it easier for concrete to flow directly underneath, and to ensure stability in the buried state.

The left and right walls 3 have a length in the front-rear direction that is larger than the diameter of the flexible tube P to be accommodated, and are equipped with fixed maintenance rods 11, which will be described later, to support the accommodated flexible tube P even if it has a large diameter. A mounting section 5 is formed along the front side. Also, concrete slab F
A fastening piece 6 is bent and extended at the lower end of the left and right walls 3 to be fastened to the surface of the temporary frame panel W which is appropriately framed in order to construct a temporary frame panel W.
By being fixed to the surface, the upright state of the support 1 itself is maintained.

A nail hole 7 is drilled in the fastening piece 6 shown in the figure in order to fix the nail 13 to the temporary frame panel W, and the nail hole 13 itself is formed long along the front and back direction of the left and right walls 3. The nail accommodating portion 9 is approximately T-shaped in plan view, and the nail accommodating portion 9
are located inside and arranged symmetrically.
By doing so, the left and right walls 3 do not expand relative to each other due to the pressure of the flexible pipe P housed in the support 1, the pressure of the concrete material being placed, and the expansion force of the support 1 itself. Even if the nail 13 is driven in, the nail 13 is housed in the nail storage portion 9, preventing the left and right walls 3 from expanding more than necessary, and increasing the installation stability. Not only that, but also the nails 13 after demolding the temporary frame panel W.
Although the head portion of the nail 13 is retained by the 6 fixing pieces around the edge of the nail hole 7, the tip of the nail 13 is removed using a tool such as pliers or pliers, as shown in Fig. 5. By holding the nail and forcibly tilting it so that its head is positioned on the straight part 8, it can be removed from the nail hole 7, and safety can be ensured when performing various subsequent operations.

In addition, as shown in the figure, the nail hole 7 in the fastening piece 6
It is also possible to form a step-like recess 10 by recessing the circumference of the part, and this recess 10 improves the appearance of the area around the nail hole 7 when viewed from below after demolding the temporary frame panel P. It can be made into something. Moreover, by not forming this recess 10 and making the entire surface of the fastening piece 6 a flat surface so that it comes into contact with the structure of the temporary frame panel W, the stability of fastening to the surface of the temporary frame panel W can be improved. I can do it.

On the other hand, the fixed maintenance rod 11 that prevents the bent and raised flexible tube P from coming out of the support body 1 and fixedly supports the bent flexible tube P is located inside the bent portion of the bent and raised flexible tube P. It is mounted on a mounting part 5 provided at the upper part of the left and right walls 3, and is made of rod material with an appropriate diameter. After mounting, both ends are bent into an L-shape (see Figure 3) or processed into a disc shape like a nail head, so that they will not come off when moved in the length direction. (See FIG. 1), etc., and other appropriate removal prevention portions 12 are formed.

The mounting section 5 itself is provided in a plurality at the front and rear of the left and right walls 3, and is set at a position corresponding to each of the flexible tubes P of different sizes, so that the flexible tubes P of different diameters can be connected to each other.
Each can be firmly fixed without wobbling.

According to this, the mounting portion 5 in FIGS. 1 and 2 has a notched groove shape communicating with the outside at the upper ends of the left and right walls 3, and according to this, the removal prevention portions 12 are preliminarily provided at both ends. The fixed maintenance rod 11 thus formed can be directly fitted and mounted on the mounting section 5. At this time, as shown in the figure, forming the retaining rod 11 in an inclined dogleg shape when viewed from the side is effective in preventing the fixing rod 11 from coming off.

The mounting part 5 in FIG. 3 has a hole shape into which the fixing and maintaining rod 11 is inserted. All you need to do is to insert the other end one after another, and then bend the other end. Once the fixed maintenance rod 11 is installed, it will not be removed at all, and the pressure of the concrete material to be poured, It does not wobble even when subjected to impacts, and the mounting stability is extremely high.

In addition, by forming a bead-shaped reinforcing means around the mounting part 5 as necessary, the fixing maintenance rod 11 mounted in the groove-shaped or hole-shaped part 5 can be prevented from being distorted. As a result, the flexible tube P can be stably supported.

This device is constructed as described above, and to explain an example of its use, when a flexible pipe P such as a conduit pipe is to be set up according to a predetermined design, it is placed on the surface of the framed temporary frame panel W. At the same time, the bent portion of the flexible tube P bent in an upright manner is accommodated in the support 1, and the inside of the bent portion corresponding to the diameter of the flexible tube P is secured. A fixed maintenance rod 11 is mounted on the mounting section 5 located at , and a concrete slab F is then formed by pouring concrete material. At this time, if necessary, a standing maintenance rod 21 bent into an L-shape is inserted from the opening of the flexible tube P, so that a double-tube structure is created so that it can accommodate flexible tubes P of different sizes and diameters. It is sufficient to cover the opening of the flexible tube P with the cap body 20.
It maintains itself upright and reliably prevents the tube from entering into the flexible tube P.

Therefore, the flexible tube P to be supported in the standing position is
The flexible tube P is maintained in an upright state by being accommodated and supported within the planar substantially groove-shaped support body 1 having a front-open structure.Furthermore, although the flexible tube P is supported from the outside, the flexible tube P does not straighten. The support back wall 2 supports the restoring force and prevents it from falling down, and the left and right walls 3 support it in the left and right direction, so it can withstand external force from any direction and ensures the standing state. can be maintained.

The support body 1 itself is folded into a planar substantially groove shape with a front end opened at a support back wall 2 that abuts the outer periphery of the flexible tube P, and left and right walls 3 that continuously face the support back wall 2. Since it is bent, the flexible tube P can be supported by inserting it from the front inside the tube.
In particular, when it is lowered to the left and right sides, it is supported by the left and right walls 3, and for example, it is possible to more completely maintain the upright position, which is difficult to do with only the internal stand-up maintenance rod 21.

The fastening pieces 6 bent and extended at the lower ends of the left and right walls 3 are fastened to the surface of the temporary frame panel W with nails etc.
In addition to ensuring reliable attachment of the flexible tube P, it also prevents the support 1 from expanding once it is attached, and maintains the flexible tube P upright even under the pressure of the concrete being placed, impact, etc. The condition is not impaired.

The fixed maintenance rod 11 mounted on the mounting part 5 provided on the upper part of the left and right walls 3 of the support body 1 is located inside the bent part of the bent and raised flexible tube P.
Even if the flexible pipe P tries to move to the side of the opening of the support 1 due to the concrete material being cast, this is surely prevented and the removal from the support 1 is prevented.

Furthermore, the support body 1 can be press-molded from sheet material with an appropriate thickness, and the fixed maintenance rod 11 can be formed from a single rod material with an appropriate diameter, so it can be constructed at low cost and can be attached to the temporary frame panel W. Even if concrete is poured and buried under the same condition, the economic burden will be small. Furthermore, when burying the device, the ideal usage condition is to bury the entire device, but even if the upper half of the support 1 is exposed during burying, it must be cut off at the end of the burying process. Since it is easy to remove, it does not become a nuisance.
