Problems solved by technology

However, there is a problem that when making the opening of the liner a shape consistent with the planar circular shape of the opening of the main pipe, it is necessary to correctly determine the position of the opening on the main pipe, which may make the operation become difficult
That is, when the openings provided in advance on the liner (rubber sheet for waterproofing) deviate from the openings of the main pipe, the liner must fit the ribs of the main pipe into the rib grooves respectively, so it cannot The liner is moved in the direction of the main tube axis, and the offset cannot be simply corrected

no. 1 Embodiment approach

[0030] Hereinafter, the first embodiment embodying the present invention will be described in detail.

[0031] In each household, a branch pipe (not shown) constituting a branch pipe connected to a common tank (not shown) is connected to a sewage main pipe which is a main pipe constituting the main pipe. In order to connect the branch pipe to the sewer main pipe 1, the connecting branch pipe 2 is installed on the sewer main pipe 1 and used (refer to Figure 4 ).

[0032] As the above-mentioned sewage main pipe 1, a plurality of annular ribs 1A are juxtaposed on its outer peripheral surface, and a material that improves the strength and rigidity corresponding to the buried soil is used (refer to image 3 ). In addition, the sewage main pipe 1 is provided with a main pipe opening 3 for attaching the above-mentioned connecting branch pipe 2.

[0033] In addition, the main pipe opening 3 is usually formed by a hole tapping machine used as a work tool at the work site while considering...

no. 2 Embodiment approach

[0071] Figure 7 and Figure 8 This shows the second embodiment of the present invention.

[0072] In this embodiment, the pressing member 26 used in the first embodiment is not used, and instead of the pressing member 26, two parts composed of an upper step surface 27A and a lower step surface 28A are integrally protruding from the inner circumference of the saddle member 7. Step flange portion 26A. In addition, the contact step portion 16 of the saddle member 7 is omitted.

[0073] In the state where the connecting member 9 is screwed to the locking member 6, it is sandwiched between the stepped surface 23 of the flange portion 21 of the connecting member 9 and the upper stepped surface 27A of the secondary flange portion 26A of the saddle member 7 The spacer 24 is not pinched by the step surface 23 and the upper step surface 27A, and there is a gap S between the lower step surface 28A of the two-step flange portion 26A and the locking step surface 20 of the connecting member 9...

no. 3 Embodiment approach

[0076] Picture 9 with Picture 10 This shows the third embodiment of the present invention.

[0077] In this embodiment, the pressing member 26 used in the first embodiment is not used, and instead of the pressing member 26, the upper edge of the locking member 6 is extended and integrally formed by the upper peripheral surface 27B, the stepped portion 28B, and the lower surface. The pressing portion 26B constituted by 29B.

[0078] In the above configuration, the insertion portion 18 of the connecting member 9 is first inserted into the saddle member 7 from the upper side, and the lower surface 29B of the pressing member 26B of the locking member 9 is suspended on the abutting step 16 of the saddle member 7. on. In this state, the underside of the gasket 24 fitted directly under the step surface 23 of the flange portion 21 of the connecting member 9 is opened, and is fixed to the outer periphery of the connecting member 9 by the elastic binding force of the gasket 24. Therefore...

Abstract

Provided is a water stop rubber sheet material capable of realizing construction reliability and operation simplification when the water stop rubber sheet material is used to connect connecting branches to the main pipe formed with annular ribs. The water stop rubber sheet material is used to connect connecting branches on a planar circular shaped main pipe peristome which is formed on a main pipe with ribs, wherein, a plurality of annular ribs are juxtaposed on the peripheral surface, a rib slot for jogging the annular rib of the main pipe is provided on the other surface, and a sheet material peristome overcasts the position of the annular rib of the main pipe. The sheet material peristome has a shape composed of a pair of circular shape portions of the main pipe peristome and a pair of line portions connected to the planar circular shaped portion.

Description

Technical field [0001] The present invention relates to a water-stop rubber sheet used when connecting a branch pipe as a branch pipe to a main pipe such as a sewer main pipe as a main pipe, a water stop rubber sheet used when the connecting branch pipe is connected to the main pipe, and a rubber sheet using the sheet The branch pipe connection structure and the construction method of the branch pipe connection structure. Background technique [0002] Generally, when branch pipes such as installation pipes connected to the common tank of each household are connected to branch pipes such as a sewer main pipe constituting the main pipe to form branch pipes, the main pipe is first installed with a saddle connection branch pipe to branch the main pipe. Then connect the branch pipe to the connecting branch pipe. When installing the connecting branch pipe on the main pipe, use a tapping machine or other tool to open an opening at a predetermined position of the main pipe, and install a...
