Construction method of light steel keel cement board exterior wall

Abstract

The invention relates to an external wall construction method, in particular to a light steel keel cement board external wall construction method which includes the steps: mounting light steel keels and cement boards; cleaning a base layer comprising waterproof coiled material pavements and waterproof coiled material surfaces; brushing interface agents; mounting metal nets with diamond meshes and barbs; avoiding clinging to waterproof coiled material in paving of the metal nets, fixing the metal nets by self-tapping screws with the mounting space of 300-500mm in quincunx arrangement and making mounting points of the self-tapping screws into concave surfaces; sticking ash cakes; plastering a bottom layer, performing configuration according to the material parameter ratio of manufacturers, uniformly stirring materials, selecting manual or mechanical spraying and covering the materials with the metal nets; plastering a surface layer by a method the same as the bottom layer plastering method; performing maintenance. The plastering thickness of the surface layer cannot exceed 20mm, and the surface is finished by a spatula after plastering. The external wall construction method is applied to external wall construction, working efficiency can be effectively improved, and cost is reduced.

Description

technical field [0001] The invention relates to wall construction, in particular to an exterior wall construction method. Background technique [0002] Many modern construction projects have tight schedules, and for construction enterprises, the profits are also very low. Among them, the cost of building brick walls, pouring reinforced concrete walls and steel structure walls is high, the cycle is long, and some construction difficulties are relatively large. [0003] The light steel keel cement board wall system is currently mainly used in indoor partition walls, but due to the different requirements of exterior walls and indoor partition walls, this type of wall has not been reported in the application of exterior wall systems, but light steel keel wall systems and Compared with other exterior wall systems, it can shorten the construction period and reduce the construction cost, so it is necessary to find a suitable construction method.
