Method for anti-seepage construction between hidden frame glass window and building structure

Abstract

The invention discloses a method for the anti-seepage construction between a hidden frame glass window and a building structure, which comprises the following steps: firstly, according to the separation distance and the shape of a structural surface at a joint seam of the outer side of a window frame and the building structure, cutting a waterproof sheet material made of ethylene propylene diene rubber; adhering the waterproof sheet material to the joint seam by using a waterproof paste, and then compacting and fixing the waterproof sheet material and the joint seam of the building structure and the window frame by using an aluminum strip; fully packing the gaps between the periphery of the window frame and the adjacent building structure by using a foaming agent; and mounting a piece of glass, then packing the foaming agent in the joint seam of an aluminum sleeve frame and an adjacent structure, closing up the joint seam on the outer side of the foaming agent by using a mortar, and finally sealing joint seam by using a weatherproof sealant. According to the method, the ethylene propylene diene rubber sheet material, the foaming agent and the weatherproof sealant form a three-path waterproof thin part node, so common quality problems of the seepage on the periphery of the window frame are effectively controlled; besides, the material can be recycled for reuse, and simultaneously the maintenance caused by the seepage is reduced during engineering use.

Description

technical field [0001] The invention relates to a building construction method, in particular to an anti-seepage construction method between a hidden frame glass window and a building structure. Background technique [0002] At present, high-end hotels or office buildings adopt a large number of novel shapes composed of hidden frame glass windows and stone curtain walls in order to make the outer facades more beautiful. Because glass windows are in contact with wind and rain every day, it is necessary to ensure their functional requirements of anti-seepage, energy saving, and resistance to deformation. According to statistics, most of the external facade leakage occurs at the joints between windows and structures and window frames. The main reason is that it is difficult to control the density and continuity of filling materials such as foaming agents; After several years of use in winter and summer, the surface of the glue will age, crack, and fall off. If it is not repair...

Problems solved by technology

According to statistics, most of the external facade leakage occurs at the joints between windows and structures and window frames. The main reason is that it is difficult to control the density and continuity of filling materials such as foaming agents; After several years of use in winter and summer, the surface of the glue will age, crack, and fall off. If it is not repaired in time, rainwater will seep into the room through the weak joints between the window frame and the structure.
