Kind Code:
A
Abstract:
To solve the problem that when attempting to connect a fixture to a base plate laid on a horizontal floor with a waterproof base having a horizontal floor and a rising wall extending upward from the horizontal floor, the fixture floats due to the slope of the joint surface and the unevenness of the surface, resulting in poor adhesion and unevenness at the joint of the fixture, making it difficult to fit and difficult to form a waterproof layer.SOLUTION: Provided is a waterproof structure including: a heat insulating material laid on a horizontal floor 1 of a waterproof substrate having a horizontal floor 1 and a rising wall 2 provided upward from the horizontal floor 1; fixtures 5b, 5c, 5d each having a rising piece joined to the rising wall 2 and a horizontal piece provided continuously from the rising piece at a substantially right angle and arranged on the heat insulating material; a bonding agent 6 to bond the rising piece to the rising wall; and a waterproof layer 4 laid on the horizontal pieces of the fixtures 5b, 5c, 5d and the heat insulating material and joined to the horizontal pieces. The fixtures 5b, 5c, and 5d have claws on the horizontal pieces, and the claws are pierced into the heat insulating material. Also provided is a construction method.SELECTED DRAWING: Figure 3
