TECHNICAL FIELD OF THE INVENTION
The present invention relates to a piping structure for a waterproof floor pan.
[0002]
[Prior art]
As shown in FIG. 5, the waterproof floor pan has a piping structure for supplying water and hot water from the outside of the bathroom to the inside of the bathroom. 100 is connected by a joint 101, rises on the floor from a pipe inlet 210 formed in the waterproof floor pan 200, and is connected to a water tap or a hot water tap in a bathroom (for example, See Patent Document 1.).
[0003]

Japanese Utility Model Publication No. 1-57162 (FIG. 1)
[0004]
Further, an opening 210 for introducing a pipe is formed in a minimum necessary size for introducing the pipe 100, and a lid 220 having a pipe insertion hole 221 into which only each pipe can be inserted after the pipe is introduced. Although not shown, a gap between the pipe insertion hole 221 and the pipe 100 is sealed by a caulking material or the like in a watertight manner.
[0005]
In addition, a header pipe construction method that has been widely used is that a long pipe branched from a main water supply pipe or a main hot water supply pipe in a octopus shape through a header is connected to a water faucet of each water supply facility such as a bathroom. This is a method of connecting one-to-one with a branch pipe that is branched from the main water supply pipe or main hot water supply pipe in order through a joint, and then connected to the faucet of each water supply facility. In comparison, the number of connection points at the joint is small, so that water leakage due to poor construction can be suppressed, and the flow rate change is small at the time of simultaneous use of the water circulating equipment, so that stable water supply and hot water supply are also possible.
[0006]
Even when a header piping method is used as a piping method for the bathroom unit to the waterproof floor pan, the number of connection points at the joints is small, and water leakage due to poor construction can be suppressed.
However, as shown in FIG. 5, when the pipe is started up by the joint 101, the alignment of the pipe at the opening 210 for introducing the pipe is easy, but when the header pipe method is used, a long pipe is required. Since the joint is not used near the lower part of the opening for introducing the piping, there is a problem that the alignment of the piping is difficult.
[0007]
Further, the pipe insertion hole 221 of the lid 220 as shown in FIG. 5 does not prevent the pipe from being centered, but the long pipe is curved to rise to the opening or is formed in a coil shape. Due to being wound and sold and having a winding habit, long pipes face various directions at openings for introducing pipes. For this reason, there is a problem that stress is generated from the long pipe to the lid 220, and watertightness between the waterproof floor pan and the lid 220 cannot be ensured.
[0008]
[Problems to be solved by the invention]
In view of such circumstances, an object of the present invention is to provide a waterproof floor pan in which piping can be easily aligned at an opening for introducing piping and watertightness can be ensured.
[0009]
