DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for horizontally supporting a rafter for a shed pipe between two columns in water pipe work in a building.

[0002]

2. Description of the Related Art In recent years, in a water pipe construction such as water supply and hot water supply in a building, a flexible resin made of synthetic resin shown in FIG. After the pipe (sheath pipe 1) has been piped, concrete casting or the like is performed and the concrete pipe 3 is buried in the concrete floor 3 and the like. Then, a flexible pipe (carrier pipe 2) made of synthetic resin for supplying water or hot water into the sheath pipe 1 is provided. ) Through the Saya pipe header construction method is widespread.

In the sheath pipe header method, as shown in FIG. 14, a sheath pipe rafter 5 is provided horizontally between two vertically provided column members 4, 4, and is used for a sink, a washroom, a bathtub, and the like. A faucet joint box 6 connected to a faucet is fixed to the rafter 5 for the sheath tube, and the end 1a of the sheath tube 1 and the end of the carrier tube 2 raised from the floor are joined to the faucet joint box 6. I have.

[0004] In order to provide the rafter 5 for the sheathing pipe horizontally between two pillars, conventionally, as shown in Fig. 14, both ends of the rafters 5 for the sheathing pipe are horizontally placed on two pillars 4, 4 made of wood. And the end 5a of the sheathing rafter 5 is nailed to the pillar 4 to fix the sheathing rafter 5 horizontally.

[0005]

However, in this way, the rafter 5 for the sheath tube is placed horizontally between the two pillars 4, 4 and both ends thereof are fixed, and the end 5a is securely fixed by nailing. Requires specialized skills, so that in addition to the water pipe builder, a specialized contractor is required only for fixing the rafters 5 for the sheath pipe, which requires labor costs and time.

In addition, since the ends 5a and 5a of the rafter 5 for the sheath tube are nailed by being applied between the two pillars 4 and 4, not only it takes much time but also the fixed support is unstable. Was. In recent years, hollow studs made of hollow metal have become widespread as pillar materials. However, the conventional method using nailing 7 has not been able to fix and support the rafter 5 for sheath pipes on the light studs.

The present invention solves such a problem, and can easily perform the fixing work even by a water pipe worker without requiring a specialized contractor, and can surely fix and support the fixing member. It is an object of the present invention to provide a rafter support for a sheath tube which can be fixedly supported by a lightweight stud.

[0008]

In order to achieve the above object, a rafter support for a sheath tube according to the first aspect of the present invention includes a mounting piece having a mounting hole for mounting on a pillar, and a rafter for a sheath tube. In order to receive a side surface, a receiving piece vertically protruded from one side of the mounting piece, and a projecting piece vertically protruding from two sides perpendicular to the side of the mounting piece, respectively, in the same direction as the receiving piece. Two arm pieces, on the wall surface of the column, screwed and fixed to the wall at the mounting hole of the mounting piece, and on the opening surface having a bent edge of the column, A bolt is inserted from the mounting hole of the mounting piece, and a plate nut screwed to the tip side of the bolt is bent and fixed to the bent edge from the inside, so that even when wood is used as a pillar material, Even when fixing to the wall of a lightweight stud, , Even when a light-weight studs having an open face, the support can be easily fixed, it is possible to reliably support the rafters for sheath tube by the receiving piece and two arm pieces of the support.

According to the second aspect of the present invention, the rafter is screwed in the fixing hole of the arm piece, so that the rafter can be more securely fixed and supported.

According to the third aspect of the present invention, since the bending projection is provided at the end of the mounting piece opposite to the receiving piece, the bending projection is bent so as to be formed on the opening surface of the lightweight stud. When the rafter support for the sheath tube is fixed, the projection in the bending direction is inserted into the opening, so that it is possible to prevent the lateral displacement.

According to a fourth aspect of the present invention, there is provided a mounting piece having a mounting hole for mounting to a pillar, and a bottom face of the rafter vertically projecting from one side of the mounting piece for receiving one side surface of a rafter for a sheath. And a receiving piece having a fixing hole for screwing the mounting member, wherein the mounting edge of the mounting piece is screwed and fixed to the wall surface of the mounting member on the wall surface of the column material, and a bent edge portion of the column material is provided. Since a bolt is inserted through the mounting hole of the mounting piece into the opening surface having the above, and a plate nut screwed to the tip side of the bolt is fastened to the bent edge portion from the inside, and fixed. Whether it is wood, a lightweight stud, or a lightweight stud with an open surface, the support can be easily fixed, and the bottom of the rafter for the Saya pipe is screwed in the fixing hole of the receiving piece. Can be.

After being bent in the opposite direction to the receiving piece 12 or the like in the elongated hole 15a as shown in FIG. 8, the rafter support 10 for the sheath is fixed to the lightweight stud 24, so that it is folded as shown in FIGS. Since the bending claw piece 15 fits into the opening 26 of the lightweight stud 24, there is no possibility of the lateral displacement of the rafter support device 10 for the sheath tube.

When the dimensions of the lightweight stud 24 are large,
As shown in FIG. 10, the rafter support for the sheathing tube is turned sideways, and the bolts 28 and the plate nuts 27 are similarly used to tighten the bolts and the plate nuts 27 using the large plate nut 27 that fits the lightweight stud 24. 10 is fixed to the lightweight stud 24.

When fixed in this way, the rafter 5 for the sheath tube
The upper surface 5e and the bottom surface are screwed in fixing holes 13a and 14a of the arm pieces 13 and 14, respectively.

The vertical length of the mounting piece 11 of the rafter support 10 for the sheath tube in the embodiment of FIG. 1 is shown in FIG.
, The upper ends of the arm pieces 13 and 14 may coincide with the upper ends of the mounting pieces 11. When the rafter support 10 for the sheath tube is also fixed to wood or a lightweight stud without an opening, it can be turned 90 ° from FIG. Also in this embodiment, a fixing hole (not shown) for screwing to the sheathing rafter 5 may be provided in the receiving piece 12.

As shown in FIG. 12, the two arm pieces 13 and 14 may be omitted from the rafter support 10 for the sheath tube of FIG. In this embodiment, a fixing hole 12a for fixing a screw is provided in a receiving piece 12, and a wooden pillar 20 and a lightweight stud 2 are provided.
2. All of the lightweight studs 24 with openings are fixed in the same manner as in the embodiment of FIG.
b is fixed in the fixing hole 12a of the receiving piece 12 with a screw.

Also in this embodiment, the bending claw 15 at the upper end of the mounting piece 11 can be fitted into the opening 26 of the lightweight stud 24 by bending.

In the above-described embodiment, if the fixing member is fixed at the mounting hole at a position deviated from the end of the rafter 5 for the sheath tube among the plurality of mounting holes 11a of the mounting piece 11 of the rafter support member 10 for the sheath tube, With the pipe rafter support 10 fixed to the end of the sheath rafter 5 in advance, the sheath rafter support 10 can also be attached to a pillar.
