Corrosion-resistant structure of assembled building exterior wall dry hanging node and construction method of corrosion-resistant structure

Abstract

The invention discloses a corrosion-resistant structure of an assembled building exterior wall dry hanging node and a construction method of the corrosion-resistant structure. The exterior wall dry hanging node comprises a pre-embedded box pre-embedded into a prefabricated dry hanging exterior wall board and a pothook seat fixedly connected with a building main body, wherein the upper part of the pothook seat enters the upper part of an inner cavity of the re-embedded box to support the whole prefabricated dry hanging exterior wall board after passing through an opening in the side of the pre-embedded box; and a grouting pipe of which the upper end is exposed out of a floor layer and the lower end is communicated with the inner cavity of the pre-embedded box is pre-embedded into the prefabricated dry hanging exterior wall board, meanwhile, a U-shaped foam stick for surrounding the exterior wall dry hanging node is arranged in a construction joint located between the prefabricated dry hanging exterior wall board and the building main body, and the pre-embedded box and the construction joint surrounded by the U-shaped foam stick are filled with filling cement slurry to wrap the whole dry hanging node. By using the corrosion-resistant structure, the dry hanging node can be prevented from being corroded for a long term, an exterior hanging wall board can be kept not to fall off, the service life is long, and the construction quality and safety performance can be ensured.

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...
