Assembly type waterproof structure of horizontal joint of external wall body and construction method of waterproof structure

Abstract

The invention discloses an assembly type waterproof structure of a horizontal joint of an external wall body and a construction method of the waterproof structure. The structure includes a lower prefabricated wall plate, a reinforced concrete beam is poured on the upper portion of the lower prefabricated wall plate, one part of water-stop rubber belt is embedded in a groove above the left end of the reinforced concrete beam, and water penetration is effectively prevented; the upper portion of the water-stop rubber belt is fixed with an upper prefabricated wall plate to form a first joint, thefirst joint is filled with non-shrinkage grouting materials, and the waterproof effect is enhanced; the left sides of the prefabricated wall plates are provided with a thermal insulation layer, the left end of a second joint on the thermal insulation layer is provided with a polyethylene foaming bar, and water penetration is effectively prevented; the left side of the thermal insulation layer is provided with an external wall protection layer, a third joint of the external wall protection layer is obliquely arranged, and water penetration is prevented through the gravity effect; the third joint is filled with non-shrinkage grouting materials, the left end of the third joint is provided with a weatherproof building sealant in a sealing mode, and the two materials are cooperated in preventing water penetration. The structure is simple, the waterproof effect is good and construction is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a waterproof structure at horizontal joints of an assembled outer wall and a construction method thereof. Background technique [0002] The construction of reinforced concrete structures by prefabrication method is one of the main ways to realize the industrialization of construction. Generally, the external wall components of prefabricated reinforced concrete are waterproofed and decorated in the professional component workshop. However, the waterproof treatment of the connection nodes of each prefabricated external wall panel can only be carried out at the construction and installation site. At present, in the domestic prefabricated building system waterproofing projects, the relevant standards and atlases for waterproofing measures for roofs, bathrooms and kitchens are relatively mature, while the waterproofing measures for prefabricated external walls are relat...

Problems solved by technology

Generally, the exterior wall components of prefabricated reinforced concrete are waterproofed and decorated in the professional component workshop. However, the waterproof treatment of the connection nodes of each prefabricated exterior wall panel can only be carried out at the construction and installation site.

At present, in the domestic prefabricated building system waterproofing projects, the relevant standards and atlases for waterproofing measures for roofs, bathrooms and kitchens are relatively mature, while the waterproofing measures for prefabricated external walls are relatively simple, mainly through simple caulking, waterproofing poor effect
