2. Description of the Related Art In general, drainage stacks and drain horizontal branch pipes in middle- and high-rise apartment buildings are connected to drainage joints at joints. 2. Description of the Related Art In recent years, floors without steps have been required to be designed in houses to prevent the elderly from tripping. For this reason, the so-called stepped slab method, in which the level of concrete slabs is lowered, is adopted especially in places where drain horizontal branch pipes are laid under the floor, such as bathrooms, laundry or kitchen sinks. In general, wall drain type is the mainstream, and when connecting the drain pipe of these toilets and the horizontal branch pipe from the bathroom, washing place or kitchen sink to one drain pipe joint, A two-stage branch collecting pipe joint in which a horizontal branch pipe joint port is formed in upper and lower two stages has been adopted.

On the other hand, when connecting a standpipe to a collecting pipe joint,
Backfilling is commonly performed after positioning the standpipe to achieve straightness of the standpipe. During backfilling work, the uprights must be supported to maintain the straightness of the uprights.
As shown in FIG. 7, a standing band 51 is wound around the standing pipe 5,
Anchor bolts 5 are attached to the wall 7 via the upright band attachment 52.
3 or a general steel bar 55 fixed to the lower surface of the concrete slab 2 is formed in a substantially "string" shape as shown in FIG. Tube 5 to U
Positioning or steadying of the pipe was performed by fastening with the bolt 56.

[0004] However, fixing the standing pipe 5 itself with the standing band 51 or the U-bolt 56 may cause a squeak sound due to the expansion and contraction of the standing pipe 5 during drainage, and may also cause the standing band mounting tool 52 to be attached. In addition, the work of mounting the general shape steel 55 on the wall 7 or the lower surface of the slab is troublesome and increases the cost.

[0005] Therefore, there has been a need for a method for supporting a standpipe at a pipe joint to which the standpipe is connected instead of the standpipe. In particular, in the conventional method of supporting a two-stage branch collecting pipe joint, when the two-stage branch collecting pipe joint is formed of an integral casting, the upper horizontal branch pipe fitting port and the lower horizontal branch pipe joint of the collecting pipe joint are formed. A method has been performed in which an annular flange portion is formed over the entire circumference between a pipe joint port and a support member for receiving the weight of a standpipe, a horizontal branch pipe, or a collecting pipe joint on the lower surface of the annular flange portion. Was.

[0006]

However, there are various types of joint pipe joints for a two-stage branch, for example, an upper joint portion having at least one transverse branch pipe joint port and at least one transverse branch pipe. A lower joint part having a joint port is formed separately,
Some support members 60 are formed so as to be connectable with a flange portion on each facing surface.
As shown in the figure, a band member 61 for fixing the tubular portion at a position not interfering with the horizontal branch pipe joint port,
1 has a high cost because it is configured with the support member 62 that supports the pipe 1. Therefore, the use of the conventional support member 60 with improvement is limited in cost reduction, and a new support member for supporting the pipe joint is required. A new way was needed.

The present invention solves the above-mentioned problem, and is suitable for a two-stage branch collecting pipe joint of a type in which an upper joint part and a lower joint part are formed in two pieces, and can be easily attached at a low cost. It is an object of the present invention to provide a method for supporting a collective pipe joint that is supported by using a support member that can be used.

[0008]

The method of supporting a collective pipe joint according to the present invention is performed by the following method to solve the above-mentioned problems. That is, a method for supporting a collective pipe joint that supports a collective pipe joint that connects a standpipe and a horizontal branch pipe on a slab, wherein the collective pipe joint includes an upper horizontal branch pipe joint port, A lower joint portion having a lower horizontal branch pipe joint opening, and the upper joint portion and the lower joint portion are respectively fastened with a plurality of bolts and nuts having a flange portion on a surface facing each other, and the bolt Has an extending portion extending on the flange portion, and one end of a support member supported on a slab is attached to the extending portion of at least one of the plurality of bolts facing each other. It is characterized by being performed.

Further, in this method of supporting a collecting pipe joint, the supporting member is formed so that the other end is supported by a supporting member erected at a position avoiding the opening of the slab. It is a feature.
