Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable support for a PC board suitable for mounting on a PC board (hereinafter referred to as a precast concrete board in the present invention) and a method for mounting the support.

[0002]

2. Description of the Related Art Conventionally, the following method has been used to attach a cable supporting hanger to a ceiling slab using a PC board. First, the suspension metal fittings are screwed to the inserts embedded in the PC board in advance. Second, there is a method of applying an adhesive to the support and directly adhering it to the PC board.

[0003]

However, many problems remain in such a conventional mounting method. That is, according to the first method, since the hanging metal fitting is screwed to the insert, the structure of the hanging metal fitting requires a screwed portion and a cable suspension portion. Then, the cable suspension part extended from the screwed part is inevitably arranged at a position apart from the PC board, and in a condominium or an apartment house where the space between the PC board and the ceiling for constructing the ceiling slab is narrow. , There was a risk that support would come for the subsequent ceiling work.

Moreover, in order to embed the insert in the PC board in advance, it is necessary to fix it to the mold for building the PC board.
However, the formwork for constructing the PC board is different in material from the formwork used at the construction site, and the concrete placing surface (bed) is mainly made of steel. Therefore, in order to mount the insert to be embedded in the PC board on the concrete pouring surface of the formwork, it is necessary to open a hole for standing the stand for fixing the insert on the concrete pouring surface. Moreover,
After forming the PC board, the upright holes had to be backfilled again, which required an extremely large number of working steps.

Further, according to the second method, since it adheres to the surface of the PC board made of concrete, there is a risk that the adhesive force will be uneven and will fall off during or after wiring work.

[0006] Therefore, the present invention was created to solve the above-mentioned problems, the mounting work is extremely simple, and moreover, wiring can be performed along the lower surface of the ceiling slab, and it is supported for subsequent ceiling work. It is an object of the present invention to provide a cable support for a PC board and a method for mounting the support that are unlikely to come.

[0007]

In order to achieve the above object, the first means of the present invention is embedded in the inside of the PC board Q at one end of a pair of tightening bodies 1 which are entwined with and supported by a cable P. It comprises a cable support 10 provided with a buried portion 2 and a sticker 20 for sticking a part of the tightening body 1 of the cable support 10 to the concrete placing surface of the PC plate form R.

The second means is a method of mounting the cable support 10 which is composed of a pair of tightening bodies 1 which are entwined with the cable P and which are supported and suspended, and an embedded portion 2 which extends from one end of the tightening body 1. That is, the cable support 10 is attached to the surface of the mold R for forming the PC board Q with the adhesive 20 covering the tightening body 1 portion of the cable support 10, and the embedded portion 2 of the cable support 10 is fixed to the concrete. The purpose is to pour concrete after forming the PC plate Q after bending in the setting direction, and to erect the tightening body 1 from the surface of the PC plate Q after the mold R is removed.

[0009]

That is, according to the first means of the present invention,
The embedded portion 2 of the cable support 10 is embedded inside the concrete of the PC board Q, and the tightening body 1 of the cable support 10 is P.
The cable P is supported and suspended on the lower surface of the C plate Q.

Further, according to the second means, the tightening body 1 of the cable support 10 is adhered to the surface of the mold R while being covered with the adhering body 20. When the mold R of the PC board Q is released from the mold, the embedded portion 2 of the cable support tool 10 is embedded inside the concrete of the PC board Q, and the tightening body 1 of the cable support tool 10 is attached to the surface of the PC board Q together with the adhesive body 20. Is expressed in.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. Reference numeral 1 shown in the drawings is a pair of tightening members which are entwined with the cable P to be supported and suspended. An embedded portion 2 embedded in the PC board Q is provided at one end of the tightening body 1.
Is provided and the whole is used as the cable support 10.
The cable support 10 has a flexible linear shape, and is planned to be a bind wire in which a wire or the like is coated with vinyl resin or the like. At this time, the cable support 10 shown in FIG.
Is formed in a substantially U shape, but in addition to this, FIG. 11 (I)
Cable support tool 10 described in (III) to FIG. 12 (I)
The cable support tool 10 described in any of (II) to (II) may be used.

Reference numeral 20 is a sticking member for sticking the tightening member 1 portion of the cable supporting member 10 to the concrete placing surface of the PC plate form R. The adhesive body 20 is composed of an adhesive body 21 and a release paper 22, and an insertion hole 23 for inserting the tightening body 1 of the cable support 10 is penetrated through the adhesive body 21 and the release paper 22 (see FIG. 1). ). Further, the adhesive body 20 shown in FIG.
Indicator line 2 indicating the bonding direction of the tightening body 1 on the surface of the bonding body 21.
4 is provided. At this time, the instruction line 24 can be formed by perforation or formed by ridge processing on the surface of the adhesive body 21 in addition to printing. Further, the insertion hole 23 is formed not only by forming the through hole, but also by forming perforations and U
It is possible to form it by a character-shaped partial cut (not shown). Further, the adhesive body 21 shown in FIG. 8 is formed by forming an insertion ridge 25 into which the tightening body 1 is inserted on the surface of a plate body such as a resin plate, a steel plate, or an aluminum plate. As shown in FIG. 9, the outer adhesive body 20 can be formed into a roll shape that can be cut into individual sheets. Further, in order to use the cable support tool 10 shown in FIG. 12, the adhesive body 20 having one insertion hole 23 shown in FIG. 10 is used.

To attach the cable support 10 to the PC board Q, as shown in FIG. 2, the cable support 10 is attached to the concrete placing surface of the PC board Q, and the tightening body 1 part of the cable support 10 is attached. The body 20 is covered and adhered. At this time, the embedded portion 2 of the cable support 10 bends in the concrete placing direction and then pours concrete. Then, in addition to waiting for the concrete to harden as it is, in the winter, the boiler S may send steam to quickly dry it (see FIG. 3).

In FIG. 4, after the concrete is hardened and removed from the form R, the embedded portion 2 of the cable support 10 is embedded inside the PC plate Q, and the tightening body 1 portion is exposed. Therefore, when the PC board Q is completed, a large number of tightening bodies 1 are exposed from the surface of the PC board Q (see FIG. 5).
Then, the cables P are bundled and wired to the exposed tightening body 1 (see FIG. 6).

[0015]

As described above, according to the present invention, since the wiring can be provided along the lower surface of the ceiling slab by the above-mentioned structure, the possibility that the subsequent ceiling work will be supported is eliminated.

That is, according to claim 1, since the tightening body 1 is exposed on the surface of the PC board Q, the cable P can be directly routed along the lower surface of the ceiling slab. Therefore, there is no risk of supporting the subsequent ceiling work.

Further, according to claim 2, the cable support 10 can be mounted by simply adhering the cable support 10 to the concrete placing surface of the form R for forming the PC board Q with the sticking body 20, so that the conventional insert is used. In addition, there is no need for any work such as opening a hole for standing the stand to fix the insert on the concrete pouring surface. Moreover, since the embedded portion 2 is embedded inside the PC plate Q when the PC plate Q is formed, P
As with the conventional one adhered to the surface of the C plate Q, the adhesive strength becomes uneven, and the possibility that the adhesive may come off during or after the wiring work is eliminated.

As described above, according to the present invention, the mounting work is extremely simple, and furthermore, the wiring can be performed along the lower surface of the ceiling slab, and there is no fear that the subsequent ceiling work will be supported. It has various beneficial effects.
