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 external wallboard. The fair-faced concrete composite external wallboard comprises a fair-faced concrete structural layer and a heat-insulatinglayer arranged on the surface of the fair-faced concrete structural layer; the fair-faced concrete structural layer is produced by a reverse beating process and has a thickness of 160 mm to 300 mm; the heat-insulating layer is subjected to spraying construction after the fair-faced concrete structural layer is poured and has a thickness of 0.5 mm to 5 mm; and a pre-embedded mechanism is arranged on the fair-faced concrete structural layer. The design of pre-embedded pieces is taken into full consideration, the demand in the aspect is perfected as much as possible, demolding and mounting of inclined struts during later mounting are taken into full consideration at the design stage, and demolding embedded pieces and the inclined struts are integrally designed, so that the varieties of the pre-embedded pieces are reduced; the demolding embedded pieces are pre-embedded bolts, the specification of the pre-embedded bolts is selected according to wallboards with different weights, vertical watertightness between the wallboards adopts combination of a waterproof material and concrete during construction of the external wallboard, and a construction process adopts the spraying constructionmethod, so that a back formwork erecting process is avoided and the construction difficulty is reduced.

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...
