In the present situation where the house is designed to eliminate the level difference on the floor as the aging progresses, it is thin to reduce the clearance under the floor, and there is a branch pipe through which the release wire is passed in order to remotely control the opening and closing of the drain plug. It was difficult to form such a drainage cross joint, and it was also difficult to construct the piping.
Therefore, it has become possible to improve the formability by dividing and forming a thin and complicated drainage cross joint into a joint body having an upper surface portion opened and an annular flange portion closing the opening. However, even if such a product could be molded, the joint body of the drainage cross joint was made thin, so the volume was reduced, and the discharge force to the drainage drain pipe due to this volume of drainage was reduced. It has been reduced, making the flow worse.

  In addition, such a drainage cross joint has a structure in which an annular collar is fixed to the upper surface of the joint body, so if the annular collar is attached to a bathtub and firmly fixed, When stress is applied to the drainage / drainage pipe protruding long to the side, a large reaction force is generated by the lever action, and the fixing portion of the annular flange portion to the joint body is easily cracked.

  In addition, even if the drainage cross joint provided with the drainage drain pipe and the branch pipe through which the release wire passes can be piped under the floor with a narrow clearance, the drainage drain pipe and the branch pipe through which the release wire passes. However, in order to solve this problem, there is a disadvantage that a plurality of types of drainage cross joints must be prepared.

  In the present invention, even if the underfloor clearance is narrow, the thin flat can be made into a drainage cross joint, thereby facilitating piping construction, and even if it is a thin flat, the drainage drain pipe The structure is such that the discharge capacity of the waste water does not decrease. And even if the position of the branch pipe through which the drainage drain pipe and the release wire pass are different, only a few types of joint bodies and caps are used to specify the position of the branch pipe through which the drainage drain pipe release wire passes for the piping construction. It is an object of the present invention to provide a drainage cross joint that enables a plurality of types of pattern piping construction by combining them.

  The drainage cross joint according to claim 1 is a flat drainage cross formed of a low polygonal column in which a water supply / drainage port is formed on an upper surface portion and a drainage drainage pipe, a branch pipe through which a release wire is passed, and the like are provided on a side surface portion. A joint comprising a joint body having an opening formed on a side surface thereof and a cap that closes the opening, and the cap is used in close contact with the joint body.

  In the drainage cross joint according to claim 2, the shape of the flat polygonal column joint body is formed with a truncated pyramid-shaped drainage guide portion on the side surface where the drainage drainage pipe is disposed, and at the symmetrical position. A substantially cubic storage part for increasing the volume is formed.

  The drainage cross joint according to claim 3 is formed with a water supply / drainage port on the upper surface portion, and at least a branch pipe through which the drainage / drainage tube and the release wire are passed on the side surface portion, and a joint body formed with an opening, and the opening It consists of a cap that closes.

  The drainage cross joint according to claim 4 is provided with a branch pipe through which at least the release wire is passed through the cap.

  The drainage cross joint according to claim 5 is in the form of a cap and an opening that can change the direction in the vertical direction or the horizontal direction when the cap is closed to the opening of the joint body.

  In the drainage cross joint according to claim 6, a cap having a branch pipe through which a release is passed is closely joined to the opening of the joint body, and the opening is closed even if the vertical or horizontal direction of the cap is changed. It is a mutual form of the cap and the joint body opening.

The drainage cross joint according to the present invention is a thin and flat joint body having a joint body with an opening formed on the side surface and a cap with which the opening is closed. And the cap can be molded separately, and it is easy to mold, and the joint body increases the storage volume by providing a substantially cubic storage part, increasing the discharge force from the drainage drain pipe, In addition, by providing the drainage guide portion at the position where the drainage drain pipe is disposed, the discharge to the drainage drain pipe can be made a fluent flow without causing a vortex.
And even if the drainage drain pipe and the branch pipe through which the release wire is passed are formed on the side surface portion of the drainage cross joint, and the directionality is generated, only a few kinds of joint main bodies and caps are prepared. By simply combining these, piping construction in a plurality of types of patterns can be easily performed.
