A construction method of an external wall of a building

Abstract

The invention provides a construction method of an external wall of a building and belongs to the field of building. The method comprises the steps of wall body outside surface layer construction, thermal insulation layer laying, wall body location, wall body spray construction, and wall surface painting. The method is high in construction efficiency, reduces the labor intensity of construction workers and the work risks, is convenient, facilitates the transportation of construction materials, improves the bonding force of a wall body outside decoration plate and a wall body and enables the external wall of a building to be beautiful and durable.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a method for constructing an exterior wall of a building. Background technique [0002] Traditional building exterior walls, when constructed, mostly adopt the following steps, 1. Wall positioning, 2. Masonry wall, 3. Exterior wall painting, 4. Insulation layer laying, 5. Exterior wall surface layer construction; Taking a building as an example, step 1 is to plan the position and structural form of the wall to be built on the load-bearing body such as floors, beams, columns, etc.; step 2 is to use blocks such as bricks at the fixed position , cement blocks, etc. for masonry; step 3 is to paint a layer of cement mortar on the outer surface of the masonry wall; step 4 is to lay a layer of insulation on the outer surface of the wall in order to achieve energy-saving requirements, so as to facilitate the building The overall thermal insulation; step 5 is to install a decorative protectiv...

[0002] Traditional building exterior walls, when constructed, mostly adopt the following steps, 1. Wall positioning, 2. Masonry wall, 3. Exterior wall painting, 4. Insulation layer laying, 5. Exterior wall surface layer construction; Taking a building as an example, step 1 is to plan the position and structural form of the wall to be built on the load-bearing body such as floors, beams, columns, etc.; step 2 is to use blocks such as bricks at the fixed position , cement blocks, etc. for masonry; step 3 is to paint a layer of cement mortar on the outer surface of the masonry wall; step 4 is to lay a layer of insulation on the outer surface of the wall in order to achieve energy-saving requirements, so as to facilitate the building The overall thermal insulation; step 5 is to install a decorative protective layer on the outer surface of the laid insulation layer, such as decorative boards, granite slabs, so as to facilitate the beautiful and durable appearance of the building; the defect of this construction method is that the construction efficiency Low, because the scaffolding used for construction needs to be built many times; the risk of construction workers is high, because when constructing on the outer surface of the outer wall, the construction workers are working on the outside of the building, and the psychological fear increases when the height is relatively high; the labor intensity is high , because the wall has already been constructed during the construction of the exterior wall, and the construction space is small; the material transportation is complicated, because all materials need to be transported from the outside of the building, and it is difficult to meet all the working surfaces; Negative wind pressure exists between the wall materials, which can easily damage the external wall materials
