Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fixing bracket for fixing a pipe joint to a floor surface or a wall surface, and more particularly to a fixing fitting for a pipe joint that is used by being mounted in a groove provided on the outer periphery of the pipe joint.
[0002]
[Prior art]
Conventionally, as a method for taking out a piping kit in which a pipe and a pipe joint are connected in advance from the bottom of the building onto the floor and fixing the joint portion to the floor surface, there are pipe fitting fixing fittings shown in FIGS. This fixing bracket is a combination of three parts and uses a pipe joint on the floor of a building, and has an arc-shaped inner circumference in the groove F of the pipe joint A having a groove F on the outer circumferential surface. The half plates B and B ′ are fitted, and the hexagonal hole plate C that fits the hexagonal portion of the outer surface wrench of the pipe joint A is overlapped and attached, and the half plates B and B ′ and the hexagonal hole plate C are attached. The holes D for the respective wood screws are made to coincide with each other and fixed to the floor surface using the wood screws E.
Since the half plates B and B ′ are fitted in the groove F of the pipe joint A, the pipe joint does not move in the vertical direction. Since the hexagonal hole plate C is fitted to the outer hexagonal portion of the pipe joint A, the pipe joint is fixed without rotating.
[0003]
[Problems to be solved by the invention]
However, the half plate B, B ′ and the hexagonal hole plate C must be attached to the floor surface, and the construction is troublesome. Further, since the hexagonal hole plate C cannot be attached to the joint if a pipe is connected to both ends of the pipe joint A, it is necessary to make sure that the assembly order is correct, and the construction is troublesome. Further, the half plates B and B ′ have a problem that they are dropped and lost during construction.
The present invention solves the above-mentioned problems, can be easily mounted and fixed to a pipe joint, and can be fixed even after connecting pipes to both ends of the pipe joint, so that installation errors do not occur and installation is easy. Providing a fixing bracket.
[0004]
[Means for Solving the Problems]
The gist of the present invention is a fitting for a pipe joint having means for preventing the movement of both the axial direction and the rotational direction of the pipe joint for fixing the pipe joint to the floor surface or the wall surface. When there are two overlapping portions on the circumference, the overlapping portions overlap in a stepped manner while keeping one surface flat, the inner circumferential inner surface fits into the groove provided in the joint, An overlapping portion grips a wrench corner piece of a pipe joint.
[0006]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a state where a fitting 10 for a pipe joint according to the present invention is mounted on a pipe joint 20. The fixture 10 has two half plates 11 and 12 assembled in a hinged manner with screws 13. The part where the half plates 11 and 12 are overlapped and connected is provided with overlapping portions 14 and 15 bent stepwise by the thickness of the plate so as to overlap each other as shown in FIG. The overlapping portion is assembled with a screw 13 having a hinge function.
[0007]
The wrench hanging hexagonal portion 22 of the pipe joint is provided with a circumferential groove 21 at a depth substantially equal to the hexagonal portion piece 22, and when the plates 11 and 12 are matched as shown in FIGS. As shown in FIG. 3, the inner surface 23 of the hole has a substantially arc shape. Since the inner surface 23 has an arc shape on the same plane, the inner surface 23 is fitted into a circumferential groove 21 provided in a wrench hanging hexagonal portion of the pipe joint.
[0008]
Further, as shown in FIG. 3, the inner shapes of the overlapping portions 14 and 15 of the plates 11 and 12 are linear pieces 18 and 19, which are matched with the hexagonal piece 22 of the pipe joint indicated by the broken line. Accordingly, since the overlapping portions 14 and 15 are bent stepwise upward from the center of the hexagonal piece 22 of the pipe joint, the straight pieces 18 and 19 protrude from the circumferential groove 21 of the joint and are aligned with the hexagonal piece 22. It is held in a rotation-stopped state.
In this state, the plates 11 and 12 are fixed to the floor surface 30 with screws 13 through the screw holes 16, 16 and 16. For this reason, the pipe joint 20 is fixed to the floor surface 30 in a non-rotating state.
[0009]
A general construction procedure for fixing to the floor surface is to first make a through hole 31 in the floor plate 30, and then connect the pipe joint 20 to the end of a prefabricated pipe formed of a flexible pipe 40 such as a polybutylene resin pipe. The pipe joint 20 to which the pipe 40 is connected is lifted from below the floor through the through hole 31, and the fixture 10 is attached to the groove 21 of the pipe joint 20 on the upper floor. Then, it fixes to the floor board 30 with the wood screw 13. FIG. After that, the vertical pipe 50 for connection is connected to the pipe joint 20 to a faucet instrument in the building. When the vertical pipe 50 indicated by the broken line is screwed into the pipe joint 20, the pipe joint 20 is fixed to the floor surface 30 in a non-rotating state, so that the vertical pipe 50 can be easily connected.
[0010]
In addition, although the said Example is an example in which the external shape of a pipe joint is a hexagonal column, it is applicable not only to this but to other shapes, such as a square column, similarly.
In the said Example, it has a means to hold | grip firmly with respect to the external force of an up-down direction, and a means to hold | grip firmly so that the pipe joint 20 may not rotate. That is, when the vertical pipe 50 is screwed clockwise into the pipe joint 20, the hexagonal piece 22 of the pipe joint 20 is applied to the inner straight pieces 18, 19 of the overlapping parts 14, 15 of the plates 11, 12 as shown in FIG. Because of the contact, rotation of the pipe joint 20 can be prevented. Further, with respect to the external force in the vertical direction, the inner peripheral surface 23 of the plates 11 and 12 is fitted into the circumferential groove 21 of the pipe joint 20 and reliably supported. Further, it can be easily mounted and fixed to the pipe joint, and can be easily fixed because it can be mounted from the outside of the side of the pipe joint even after the pipe is connected to both ends of the pipe joint.
[0011]
【The invention's effect】
As described above, the fitting for a pipe joint according to the present invention can be easily attached and fixed to the pipe joint, and there is no mounting error, and the pipe joint is attached to the inner surface of the building in the axial direction and the rotational direction. It is a fixture that can be easily constructed in a state where both are blocked.
