Drain connection and drain pipe using same

Abstract

The present invention relates to a drain pipe joint capable of improving the workability of the drain piping equipment, and a drain pipe structure using the same. The drain pipe joint 20 functions to conjoin drainage discharged from drain branch pipes 11 to 15 extending from a plurality of drain fittings 1 to 5, respectively, and to discharge the drainage to a downstream drain main pipe 16. The drain pipe joint 20 has a cylindrical joint main body 22, one end of which is provided with discharging opening communicated with a drain main pipe 16, and has a plurality of branch pipe connection portions 24, which may be connected to each of the drain branch pipe 12 to 15, formed in a peripheral wall thereof. The side surface and the upper surface of the joint main body 22 are provided with one or more branch pipe connection portions 24 respectively.

Description

technical field [0001] The present invention relates to a drainage pipe joint for converging the drainage inflowing from various drainage branch pipes extending from a plurality of drainage facilities such as houses (such as toilets and bath rooms) to flow out to a main drainage main pipe on the downstream side, and a drainage pipe structure using the same . Background technique [0002] As the above-mentioned drain pipe joint, for example, a configuration described in Patent Document 1 below is known. The drain pipe joint (drain bucket) described in this patent document 1 is constituted by: a cylindrical joint main body (bucket main body) which has a larger cross-section than the main drain main pipe located on the downstream side of the joint (in particular, the dimensional ratio in the height direction of the cross-section). The size of the drain main pipe is large); the branch pipe connection part (branch inlet), which is a part protruding from the side of the above-men...

AI Technical Summary

Problems solved by technology

[0005] However, in the drain pipe joint of Patent Document 1, since the branch pipe connecting portion connecting each of the branch drain pipes is provided only on the side of the joint main body, it may be difficult to drain the water when there is an obstacle on the side of the drain pipe joint, for example. Connection of branch pipe to drain pipe joint

[0006] In the drain pipe joint of Patent Document 1 described below, since the connection between each branch drain pipe and the branch pipe connection part can only be performed in a state where the axes of the two are aligned, there is a fear of inconvenience in piping construction.

[0007] In addition, in the drain pipe joint of the above-mentioned Patent Document 1, since the cross-sectional height dimension of the joint main body is much larger than that of the above-mentioned drain main pipe, it may be difficult to perform the drain pipe joint especially in a low-floor house with a narrow underfloor space. set up
