Problems solved by technology

[0003] The current composite exterior wall panels still have the problem of low construction efficiency. During the construction process, it is still necessary to repeatedly measure and calculate the values, and the integrated construction cannot be carried out. In addition, the thermal insulation effect needs to be improved.

Abstract

The invention discloses a fair-faced concrete composite exterior wall panel, comprising a fair-faced concrete structural layer and an insulating layer arranged on the surface of the fair-faced concrete structural layer. The fair-faced concrete structural layer is produced by an anti-beating process, and its thickness is 160mm-300mm. The insulation layer is sprayed after pouring the fair-faced concrete layer, with a thickness of 0.5mm-5mm, and the clear-faced concrete structure layer is provided with a pre-embedded mechanism. The present invention fully considers the design of the embedded parts, perfects the requirements in this respect as far as possible, fully considers the installation of the diagonal braces during the demoulding and later installation in the design stage, combines the demoulding embedded parts and the diagonal braces into one design, and reduces the The types of embedded parts are specified. The type of demoulding embedded parts is embedded bolts. The specifications of embedded bolts are selected according to the different weights of wall panels. During the construction of external wall panels, waterproof materials are used for vertical waterproofing between wall panels. Combined with concrete, the construction process adopts the spray construction method, which eliminates the post-formwork process and reduces the difficulty of construction.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete buildings, in particular to a fair-faced concrete composite exterior wall panel and a construction method thereof. Background technique [0002] Prefabricated structure is the abbreviation of prefabricated concrete structure, which is a concrete structure assembled with prefabricated components as the main force-bearing components. Prefabricated reinforced concrete structure is one of the important directions for the development of my country's building structure. It is conducive to the development of my country's building industrialization, improving production efficiency and saving energy, developing green and environmentally friendly buildings, and is conducive to improving and ensuring the quality of construction projects. [0003] The current composite exterior wall panels still have the problem of low efficiency in construction. During the construction process, it is still nec...
