Abstract

(57) [Summary] [PROBLEMS] To obtain a drainage joint that can install a horizontal drainage pipe without cutting a drainage vertical pipe in an apartment house. SOLUTION: A joint body provided with several U bolts fixed to a drainage standing pipe is provided with a connecting ring portion to the drainage horizontal pipe and a tightening cap nut.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a drainage joint in which a resident can connect a horizontal pipe to an existing drainage pipe to drain water in an apartment house or the like.

[0002]

[Prior art]

 Conventionally, when a collective resident installs a new water tap, as shown in FIG. 7 and FIG. 8, the drainage riser A is cut X1 and X2 at two locations above and below, and a cheese-type drainage joint C is inserted between them. The construction had been adopted. In this case, drainage stack A will be cut off, which will increase the construction time and cost. Also, except for the construction on the top floor, residents on the construction floor and above will temporarily stop drainage during the construction period. It is very inconvenient. In the figure, F indicates a floor surface.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to solve the above-mentioned problems and to obtain a drainage joint capable of shortening the construction period, reducing costs, and removing restrictions on drainage.

[0004]

[Means for Solving the Problems]

 The means of the present invention is to provide a joint body having several U-bolts fixed to a drainage standpipe with a connecting ring portion to the drainage horizontal pipe and a tightening cap nut.

[0005]

[Embodiment of the invention]

 In FIG. 1, reference numeral 3 denotes a joint body, which has an arc surface 2 joined to a drainage pipe A, a connection ring 4 connected to a drainage horizontal pipe B, and a hole 6 for attaching two U bolts 1,1. A flange 7 is formed integrally with the connection ring 4, and a fastening cap nut 5 is screwed into the connection ring 4. Reference numeral 8 denotes an O-ring provided on the connecting ring portion 4, and reference numeral 10 denotes a lock nut of the U bolt 1.

[0006]

[Action]

 The present invention uses two U-bolts, applies the O-ring of the joint main body to the side of the standpipe with the circular arc surface 2 fitted in the center of the standpipe, and fixes the upper and lower two places by tightening the U-bolt and nut I do. After the mounting, a hole 12 is formed in the standing pipe from the side of the horizontal drain pipe mounting portion of the joint body by using a carbide drill D for drilling a standing pipe and an electric drill. In this case, the inner diameter and the depth of the outer shape of the forsaw and the lateral hole of the joint body serve as a guide for drilling.

[0007]

[Effect of the invention]

 According to the present invention, the joint body does not need to stop drainage on the floor above the construction floor as in the related art, and the joint body of the standing pipe can be fixed at a predetermined position and the joint can be installed. In particular, the inner diameter and the depth of the side hole of the joint body serve as guides for drilling, and drilling can be easily performed without using special jigs and tools.
