Description

Joint part joining method of double composite waterproof sheet {COMBINING PROCESS OF COMPLETE SHEET}

The present invention relates to a joint part bonding method of a double composite waterproof sheet, and more particularly, to a joint of a double composite waterproof sheet laminated with an upper layer using a synthetic polymer system as a main raw material and a bottom adhesive layer using rubberized asphalt and unvulcanized butyl rubber. In the partial joining method, the synthetic polymer system is formed on the upper part of the joint overlapping part in the state where the joint edges of the double composite waterproof sheet laminated with the upper layer using the synthetic polymer system as the main raw material and the lower adhesive layer using the rubberized asphalt and the unvulcanized butyl rubber are overlapped. It relates to a seam partial joining method of a double composite waterproof sheet bonded using an upper layer using a main raw material.

The structure of the double composite waterproof sheet at the initial stage of the development and use of the double composite waterproof sheet is laminated on both sides of the upper layer using the synthetic polymer system as the main raw material and the width of both sides of the lower adhesive layer using the rubberized asphalt and the unvulcanized butyl rubber. A double composite waterproof sheet laminated with an upper layer using an unformed synthetic polymer system as a main raw material and a bottom adhesive layer using rubberized asphalt and unvulcanized butyl rubber. The conventional waterproofing method using such a double composite waterproof sheet is a double-walled structure wall. At the same time, one side of the composite waterproof sheet is closely adhered, and the waterproof adhesive layer of the double composite waterproof sheet is closely adhered to the bottom of the structure, and then the right side of the double composite waterproof sheet is on the upper layer using the other synthetic polymer system as the main raw material of the double composite waterproof sheet. Part of lower adhesive layer using rubberized asphalt and unvulcanized butyl rubber This method is repeated and connected by double composite waterproof sheet. At the finishing stage of coating waterproofing, the other end of the final double composite waterproof sheet is cut to be in close contact with the wall of the structure and adhered to the wall. The lower adhesive layer using rubberized asphalt and non-vulcanized butyl rubber is adhered to the bottom to be adhered to complete the film formation of the double composite waterproof sheet.

The waterproofing method obtained using the double composite waterproof sheet does not connect the lower adhesive layer using rubberized asphalt and unvulcanized butyl rubber to form an integral full layer coating layer of the lower adhesive layer using rubberized asphalt and unvulcanized butyl rubber. In the joint, a lower adhesive layer using rubberized asphalt and unvulcanized butyl rubber is bonded between the upper layer using the synthetic polymer system as the main raw material and the upper layer using the synthetic polymer system as the main raw material, but the adhesion between the foreign materials is poor and the synthetic polymer system is used as the main raw material. Adhesion is poor due to the original return force caused by the severe decoration of the upper layer. Also, when the surface layer is formed by shear force or concrete mortar generated when the roller is compacted after forming the entire layer with the coating waterproof sheet Phenomena occurring during work such as impact or shear force After forming the surface layer with synthetic resin coating material, polyurethane resin, epoxy resin, etc. to complete waterproofing, high viscosity rubberized asphalt adhered between heterogeneous inner layers by various types of impact, shear force, etc. The lower adhesive layer is easily pushed out using the unvulcanized butyl rubber, which worsens the adhesive state.

In order to solve the above problems and at the same time, according to the demand of more effective waterproofing method, various types of double composite waterproof sheets with margins have appeared. When introducing such multilayer waterproof sheets, the upper layer and rubberized asphalt using synthetic polymer system as the main raw materials are introduced. And a double composite waterproof sheet in which a lower adhesive layer using non-vulcanized butyl rubber is laminated, a double composite waterproof sheet having a margin at the right edge of the upper layer using a synthetic polymer as a main raw material, and an upper layer and rubberized asphalt using a synthetic polymer system as a main raw material.
