Construction method of galvanized steel plate waterproof layer at inside of opening type ceramic plate curtain wall

Abstract

The invention discloses a construction method of a galvanized steel plate waterproof layer at inside of an opening type ceramic plate curtain wall. The construction method comprises the following steps of 1, measuring and lofting: determining the location and dividing size of the galvanized steel plate waterproof layer; 2, installing of a section steel arranging the section steel base on the outer wall surface of a constructed building; 3, installing of keels: installing the main keels and secondary keels; 4, constructing of the galvanized steel plate waterproof layer: fixedly connecting the galvanized steel plate and the main keels, fixedly connecting flanges of the galvanized steel plate and the secondary keels, and using sealant to seal the adjacent galvanized steel plates at the main keels, and the fixed connecting part of the flanges and secondary keels. The construction method has the advantages that the steps are simple, the design is reasonable, the construction is simple and convenient, and the use effect is good; a galvanized steel plate can form the tight waterproof layer at the inside of the opening type ceramic plate curtain plate; the galvanized steel plate waterproof layer is installed by the main keels and the secondary keels of the opening type ceramic plate curtain wall; the construction complexity is decreased, and the construction quality can be easily guaranteed.

Description

technical field [0001] The invention belongs to the construction technical field of a building curtain wall waterproof system, and in particular relates to a construction method of a galvanized steel plate waterproof layer inside an open ceramic panel curtain wall. Background technique [0002] The curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large-scale and high-rise buildings. Composed of panels and supporting structure systems, it can have a certain displacement capacity relative to the main structure or itself has a certain deformation capacity, and does not assume the role of the main structure. The building envelope or decorative structure. [0003] Curtain wall is an external wall construction method that uses various strong, light and beautiful building materials to replace the traditional mason...

Problems solved by technology

Usually, the internal waterproofing process of traditional open curtain walls in my country uses paint as a waterproof layer, but there are several defects in paint waterproofing: on the one hand, due to the need for cross-processes in the construction process, it is easy to damage the waterproof layer, causing rainwater to seep into the wall; On the one hand, the waterproof coating pollutes the surrounding environment during the construction process, which is not conducive to environmental protection, and the waterproof and corrosion resistance of the coating is poor. Over time, the waterproof coating may partially crack or fall off from the wall, causing rainwater to fall off through cracking Parts seep into the inner wall, affecting the building function
