ECP wallboard installation construction method

Abstract

The invention discloses an ECP wallboard installation construction method. The method comprises the following steps that S1, paying-off and installation of embedded parts and keels are conducted; S2, installation of Z-shaped connecting pieces is conducted, wherein installation of the Z-shaped connecting pieces comprises line drawing, drilling, connecting piece installation and temporary connecting piece fixing; S3, installation of ECP wallboards is conducted, wherein the ECP wallboards are installed in a longitudinal and transverse installation mode; S4, board seams are adjusted; S5, welding of the Z-shaped connecting pieces is conducted; S6, sealant applying is conducted; and S7, repairing of the ECP wallboards is conducted. The ECP wallboards serve as non-structural decoration components, flexible connection is adopted during installation, the self-weight loads of the boards are borne by angle steel, and the horizontal loads are borne by the Z-shaped connecting pieces. During an earthquake, the boards can move in a staggered mode through gaps between the boards, and damage and falling which may occur due to mutual collision of the boards are avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for installing ECP wallboards. Background technique [0002] At present, construction industrialization, housing industrialization and urbanization construction require active promotion of prefabricated construction. In the enclosure structure, the key indicator for assessing the level of building industrialization is the degree of assembly of the outer walls. The promotion and application of prefabricated lightweight concrete exterior wall panels is in line with the national industrial policy of green building and building energy conservation, and is an important part of the sustainable development strategy of the construction industry. At present, the main types of wall panels that can be used as prefabricated external wall panels in China are: load-bearing concrete rock wool composite external wall panels (large surface density, low install...

AI Technical Summary

Problems solved by technology

At present, the main types of wall panels that can be used as prefabricated external wall panels in China are: load-bearing concrete rock wool composite external wall panels (large surface density, low installation efficiency, which is not conducive to popularization and application), thin-walled concrete rock wool composite external walls board (the production process is more complicated, which is not conducive to popularization and application), concrete polystyrene composite exterior wall panels (the surface density is relatively large, and special cranes are required for installation, which is not conducive to the promotion and application of current building industrialization), concrete perlite composite exterior wall panels (The surface density is high, requiring a special crane for installation, which is not conducive to the popularization and application of the current building industrialization), and the steel mesh cement insulation material sandwich panel (the production process is complicated, the quality is uneven, and it does not meet the industrialization application), after comprehensive consideration, Extruded cement fiber wallboard (ECP for short) is selected. Extruded cement fiber wallboard is made of siliceous materials (such as natural stone powder, fly ash, tailings, etc.), cement, fiber and other main raw materials. A new type of building cement wall panel made of molded hollow panels and then cured by high-temperature and high-pressure steam
