A GRID PATTERN BOARD ARRANGE TYPE COMBINATION FOR COMPLEX WATERPROOF AND COMPLEX WATERPROOFING CONSTRUCTION METHOD OF BUILDING CONSTRUCTION ROOFTOP THAT USE THIS

摘要

The composite waterproof construction method of the rooftop of a building structure using the composite waterproof checkerboard type waterproof sheet combination of the present invention is attached to the wall surface and the bottom surface of a concrete slab having a vertical surface and a horizontal surface having an adhesive surface on the outer surface and forming a roof of the construction structure. A plurality of first waterproof sheets for corners; A plurality of second corner waterproof sheets having an adhesive surface on the outer surface and having a plurality of vertical surfaces disposed to be perpendicular to each other, and having one horizontal surface extending in an outward or inward direction of the vertical surface; A partition waterproof sheet having a horizontal surface having an adhesive surface on an outer surface thereof and a vertical surface extending upward from a center of the horizontal surface; The inner wall of the concrete slab that forms the roof of the construction structure is provided with a plurality of box-shaped waterproof sheets composed of rectangular or square bottoms and sides extending upward from the four ends of the bottom and having an adhesive layer on the entire outer surface. A corner waterproof sheet attaching step of attaching the first corner waterproof sheet and the second corner waterproof sheet to the wall surface and the bottom surface; A plurality of box-shaped waterproof sheets are tiled to the bottom surface of the concrete slab and bonded to each other, and the box-shaped waterproof sheet located at the outer side of the arranged state is formed by the vertical surfaces of the waterproof sheet for the first corner and the waterproof sheet for the second corner. A box-type waterproof sheet attaching step of attaching the box-shaped waterproof sheet to the bottom surface of the concrete slab by mutually bonding the bottom surface with the horizontal surfaces of the first corner waterproof sheet and the second corner waterproof sheet; A partition waterproof sheet attaching step of arranging and attaching a plurality of partition waterproof sheets while keeping a predetermined interval in spaced spaces between the first corner waterproof sheet and the second corner waterproof sheet and the box-shaped waterproof sheet; Pressing in the space between the inner space and each of the partition waterproof sheet of the tiled box-shaped waterproof sheet is characterized in that the construction is completed in the finishing step of laying the wire mesh to finish the concrete. According to this, the expansion and contraction of the pressed concrete in the box-type waterproof sheet can be made elastically according to the temperature change, so that the response to the repeated expansion and contraction of the pressed concrete can be enhanced to prevent the crack of the waterproof layer as much as possible. As the waterproof layer is divided into multiple partitions by the waterproof sheet, it is easy to check the damaged part when the waterproof layer is broken, and partial repair is possible to repair only the damaged part, thereby reducing the maintenance cost of the waterproof layer, and not removing the existing waterproof layer. Since it is possible to form a new waterproof layer in a non-state, it is possible to improve the work efficiency during waterproof construction on the roof, and to reduce the cost of dismantling the existing waterproof layer.
