1 is a configuration example of a branch pipe socket according to the present invention.

As shown, the branch pipe socket 10 according to the present invention is to be assembled in a rectangular branch hole (1a) perforated on one side of the peripheral surface of the main pipe (1).

The branch socket 10 includes a skirt 11, the auxiliary skirt 12 and the connecting tube (13).

The skirt 11 is inserted into the main pipe 1 through the branch hole 1a and is installed to be in close contact with the inside of the branch hole 1a. The skirt 11 corresponds to the curvature of the main pipe 1. It has a curved arc shape as much as possible.

In addition, the skirt 11 has a quadrangular shape, that is, a quadrilateral, in the same manner as the branch hole 1a.

In addition, the skirt 11 has an area equal to or slightly smaller than the pore size of the branch hole 1a.

The auxiliary skirt 12 is connected to at least one pair of sides of the skirt 11 so as to be folded outwardly (the opposite direction of the main pipe).

Here, the connecting means of the skirt 11 and the auxiliary skirt 12 may be a hinge (14). Alternatively, as shown in FIG. 2, the connecting means may be a bridge 15 having a thickness thinner than that of the skirt 11 and the auxiliary skirt 12.

It serves to seal the gap between them, the material of which is used as a conventional gasket, such as rubber or silicone gaskets.

The outer watertight gasket 30 is interposed between the branch pipe socket 10 and the outer surface of the main pipe 1 to seal a gap between the branch hole 1a drilled in the main pipe 1 and the outer cover 40. It is used as a material, and its material also uses a conventional material used as a gasket such as rubber or silicone.

The outer cover 40 is disposed on the surface of the outer watertight gasket 30 to securely bind the branch pipe socket 10 to the main pipe 1, and the outer cover 40 is the main pipe. It has a curved shape so as to correspond to the external curvature of (1).

The fastening member 50 serves to integrally fasten the skirt 11, the inner watertight gasket 20, the outer watertight gasket 30, and the outer cover 40, and bolts and nuts which are general fastening means In addition to this, other fastening means can be applied as well as similar functions.
