Anti-corrosion structure and construction method of dry-hanging node of prefabricated building exterior wall

Abstract

An anti-corrosion structure and a construction method of a dry-hanging joint of an exterior wall of a prefabricated building, the dry-hanging joint of an exterior wall includes a pre-embedded box embedded in a prefabricated dry-hanging exterior wall panel and a hook seat fixedly connected to a building body The upper part of the hook seat passes through the side opening of the pre-embedded box and enters the upper part of the inner cavity of the pre-embedded box to support the entire prefabricated dry-hanging exterior wall panel; The grouting pipe in the inner cavity of the box, at the same time, in the construction gap between the prefabricated dry-hanging outer wall panel and the main body of the building, there are U-shaped foam rods surrounding the dry-hanging nodes of the outer wall, and the U-shaped foam rods in the pre-embedded box Inject filling cement slurry into the surrounding construction gaps to wrap the entire dry-hanging node. The invention can make the dry-hanging nodes long-term anti-corrosion, ensure that the external wall boards do not fall off, have a long service life, and ensure building quality and safety performance.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an anti-corrosion structure and a construction method of a dry-hanging node on an exterior wall of an assembled building. Background technique [0002] At present, in Chinese buildings, glass curtain walls are mainly used for dry hanging of external walls, but in foreign countries, many public building projects use a large number of concrete external wall panels. This kind of concrete external wall panels can well reflect the overall effect of the external facade. But at the same time, there are also anti-corrosion problems at the dry-hanging nodes. This is because the dry-hanging components are made of steel, so long-term and effective anti-corrosion work is required to ensure that the external wall panels do not fall off and make them the same as the building. Longevity, ensuring building quality and safety. Contents of the invention [0003] The...
