Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig used for connecting and fixing an inflow pipe and an outflow pipe to a distribution pipe used for, for example, hot water supply or water supply.

[0002]

BACKGROUND OF THE INVENTION As shown in FIG. 8, a distribution pipe (1) of this type is composed of a main pipe (2) which is a straight pipe and a plurality of branch pipes (3) divided from the main pipe (2). At one end of the main pipe (2).
° The inflow pipe (5) is connected and fixed via the curved pipe joint (4) and the other end is closed, and the outflow pipe (7) is connected to each branch pipe (3) via the straight pipe joint (6). The outflow pipe (7) is connected and fixed, and the tip of each outflow pipe (7) is inserted into the receiving pipe (8). And the distribution pipe (1),
The pipe joints (4, 6), the inflow pipe (5), and the outflow pipe (7) are made of a thermoplastic synthetic resin such as polyethylene, polypropylene, cross-linked polyethylene, cross-linked polypropylene, and polybutene.

[0003]

2. Description of the Related Art In the above construction, pipe fittings (4, 6) are connected to one end of a main pipe (2) of a distribution pipe (1), a branch pipe (3), and an inflow pipe (5).
An adhesive or the like is used to connect and fix to the outflow pipe (7), but recently, heating wires (9,10,1)
1,12) and the heating wires (9,1) from the terminals (13,14,15,16)
0,11,12) to generate heat and melt the thermoplastic synthetic resin that is the material of the pipe joints (4,6) and pipes (2,3,5,7) in the vicinity of the pipe joints (4,6). ) And pipes (2,3,5,7) are fused and fixed.

[0004]

In the above conventional method for connecting and fixing a pipe, the pipe joint and the pipe are connected and fixed regardless of whether an adhesive is used or a heating and fusing means using a heating wire is employed. It takes some time to do so. Therefore, if the pipe joint and the pipe are displaced from each other before fixing, fixing by adhesion or fusion is naturally difficult to be performed.

[0005]

According to the present invention, a pipe joint is provided at one end of a distribution pipe (1) obtained by branching a plurality of branch pipes (3) from a main pipe (2). Connect and fix the inflow pipe (5) via (4), and connect pipe fittings to each distribution pipe (1).
A jig (17) used for connecting and fixing the outflow pipe (7) via (6), and the inflow pipe fitting groove (19A, 19B) and the outflow pipe fitting groove (21A, 21B) A pair of jig pieces (17A, 17B) formed with a hinge are hinged at one end, and a fastener mechanism is attached to one or both other ends of the jig pieces (17A, 17B). Main pipe (2) from one or both of the jig pieces (17A, 17B)
The present invention provides a pipe connection fixing jig (17) from which a hook (22) engaging with the pipe connection is extended.
