A piping space for connecting and connecting the equipment and the external piping arranged therein, and a lid is detachably disposed so as to cover the upper surface of the concave portion and to be substantially flush with the floor surface of the waterproof pan. It is characterized by having been established.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The width and depth of the concave portion on the floor of a waterproof pan used as a piping space are such that water supply / hot water pipes and drain pipes for each equipment in the equipment unit are concentrated in one concave portion. It is formed to a size that can be piped. In addition, the position of the concave portion in the waterproof pan differs depending on the arrangement position of various equipments in the equipment unit, but is mainly provided on one or two sides inside a wall panel that is erected on the outer edge of the waterproof pan.

Water supply / hot water pipes and drain pipes from the outside penetrate through the holes formed in the bottom wall or side wall of the recess and are taken into the recess, and the pipes from the outside are appropriately branched in the recess. After connecting to the branch pipe, piping to various equipment in the equipment unit connected to the branch pipe is routed through the inside of the recess, and this piping is passed through the upper surface of the lid that covers the upper surface of the recess to the equipment. Connect piping.

[0010] After connecting the equipment and the external piping arranged in the equipment unit in the recess and performing piping, the upper surface opening of the recess is covered so as to be substantially flush with the floor surface of the waterproof pan. The lid is detachably provided. Steps are formed in advance on both sides of the upper end of the opening of the recess so that both ends of the lid can be placed, and a connection portion between the floor surface of the waterproof pan and the lid has water inside the recess. Is waterproofed with a water sealant so that no water enters.
