Description of the Related Art As a building air-conditioning system, a heat pump and a heat storage tank are combined, cold water and hot water are made with cheap electricity at night and stored in the heat storage tank, and an air conditioner or fan coil unit is used during the time when air conditioning is required. Many systems that perform heat exchange and heating and cooling have been adopted. Here, the heat storage tank that stores cold water or hot water is required to have sufficient heat insulation performance to prevent heat loss and increase efficiency, and to have excellent heat insulation performance for long-term maintenance. . Therefore, it is known that a heat insulating material such as hard polyurethane foam is attached to the inner surface of the tank, and a waterproof sheet is attached on the heat insulating material. In the L-shaped corner portion between the bottom surface and the wall surface in the heat storage tank having such a structure, a strip-shaped sheet made of an alloy of EPDM and an olefin resin is formed on the inner surface of a hard L-shaped member 100 made of polyethylene as shown in FIG. The sheet 101 was attached with both ends thereof bonded (heat-sealed), and a waterproof sheet made of the same material as the sheet 101 was bonded to the belt-shaped sheet 101. However, since the heat-sealing property between the L-shaped member 100 and the band-shaped sheet 101 is not good, it is known that the L-shaped member 100 and the belt-shaped sheet 101 are manufactured by multilayer extrusion molding. Alternatively, as shown in FIG. 5, a steel plate was used as the L-shaped member 100, and a steel plate whose entire surface was covered with vinyl chloride was attached to an L-shaped corner portion, and a vinyl chloride waterproof sheet was adhered.

In this case, the belt-shaped sheet 10
There was a possibility that 1 may peel from the L-shaped member 100. In the case where the L-shaped member 100 is made of a steel plate and is coated with vinyl chloride, rust may be generated from the nail surface or the like when a nail or the like is used for attachment to the cut surface or the heat insulating material, and the steel plate and the vinyl chloride are used. There was also the problem of peeling with.
