Description

[Detailed Description of the Invention] A. Purpose of the Invention A. Industrial Field of Application The present invention is intended to provide a stainless steel waterproof swing drain having a new configuration.

B. Conventional technology and its problems Regarding this kind of technology that has been provided conventionally,
The structure is such that the drain is fixed to the frame and the face material is fixed to this drain. but,
Facing materials, especially stainless steel facing materials, repeatedly expand and contract due to temperature differences, and accidents have occurred in which the facing materials have been damaged.

B. Structure of the device A. Means for solving the problem The present application attempts to solve the above-mentioned problem with the following structure.

That is, in the present application, the first pipe joint 4 made of stainless steel and extending vertically through the center of the bottom part 2A of the water receiving part 2 consisting of the bottom part 2A and the side wall 2B is as follows.
Consisting of upper and lower tube bodies 4A and 4B that are screwed together, a piping steel pipe 5 is connected to the lower tube body 4B, and a drain hole 4A is provided at opposing positions in the upper and lower tube bodies 4A and 4B. ', 4B' are opened, and a second pipe joint 7, in which upper and lower pipes 7A, 7B are screwed together, is connected to the upper end of the bellows pipe 6 which is connected to and stands up from the upper pipe body 4A. This is a waterproof swing drain in which a horizontal edge 7A' is connected to the upper edge of the upper pipe 7A.

B. Example 1 of the invention is a stainless steel waterproof swing drain of the invention. Reference numeral 2 denotes a water receiving portion consisting of a bottom portion 2A and a side wall 2B, and an attachment edge 2C to the lower surface of the frame 3 is formed at the upper edge of this water receiving portion 2.

Reference numeral 4 denotes a first pipe joint made of stainless steel that extends vertically through the center of the bottom portion 2A of the water receiving portion, and this first pipe joint 4 consists of upper and lower pipe bodies 4A and 4B that are screwed together. A steel pipe 5 made of stainless steel for piping is connected to the lower pipe body 4B, and a drainage pipe (not shown) is further connected to this steel pipe 5.
Therefore, drainage holes 4A' and 4B' are formed in the upper and lower tubes 4A and 4B at opposite positions, and a handle 4A'' having a planar cross shape is provided in the upper tube 4A. Therefore, by supporting this handle, the upper tube body 4
When A is rotated, the drain holes 4A' and 4B' are opened and closed.

6 is a stainless steel bellows tube that is connected to and stands up from the upper tube body 4A, and an upper and lower tube 7 is connected to the upper end of this tube 6.
A second pipe joint 7 in which A and 7B are screwed together is connected. A horizontal edge 7A' is connected to the upper edge of this upper tube 7A.

C operation Explain along with the effects.

C. Effect of the invention A circular mounting hole 3A is opened at the desired location for drain installation in the frame 3, and the above-mentioned second
The pipe joint 7 is set so that the upper surface thereof is located slightly below the surface of the frame, and the mounting edge 2C is brought into contact with the lower surface of the frame and fixed with the anchor 8. Fine adjustment of the level is done by rotating the upper and lower tubes. Circular hole 9A for drain opened in face material 9 laid on the surface of the structure
is welded to the horizontal edge 7A'. In this case, the inner peripheral surface of the circular hole 3A is dimensioned so as not to come into contact with the drain 1 of the present application.

Even if the stainless steel waterproof face material expands or contracts due to temperature differences, the bellows pipe of the present application will adapt by swinging from the first pipe joint to the second pipe joint, so the face material will not expand or contract due to temperature differences. It will not break or be damaged even if it is stretched and stretched repeatedly. In addition, if rainwater enters between the facing material and the frame during construction, conventionally it will seep out and stain the surrounding area after a considerable period of time has passed after construction, but in the case of the present application, drainage is provided through drainage holes 4A' and 4B'. Because we can, we can solve these problems.
