A kind of prefabricated preparation process of prefabricated wall without facing layer

Abstract

The invention discloses a forehead preparation process for a finish coat free assembled wall. The wall comprises a concrete wall body and a heat-preservation plate, wherein the heat-preservation plate is arranged outside the concrete wall body; a protection layer is arranged outside the heat-preservation plate. According to the forehead preparation process, the assembled self-heat-preservation wall plate is produced by using a heat-preservation plate forehead construction process, and connecting parts for connecting external plates with inside and outside components in a conventional sandwich structure are not used, so that the cost can be greatly lowered, the production efficiency can be improved, the self-weight of a building can be reduced, and large-scale popularization of assembled buildings can be ensured.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to the field of manufacturing method, design and installation of a novel prefabricated wall. Background technique [0002] As the largest developing country, my country's energy consumption per unit of GDP is more than twice the world's average level. Faced with an increasingly severe energy security situation, the country is vigorously promoting energy conservation and emission reduction in various fields. Building energy consumption accounts for 20-30% of my country's total energy consumption, so building energy conservation is particularly important. The latest building energy-saving standard is that the northern regions such as Beijing, Tianjin, Shandong, Hebei, Xinjiang and other provinces have achieved 75% energy-saving standards. Most of the urban residential buildings in most areas require 65%, and very few areas require 50%. Due to the late development of buildi...

Problems solved by technology

However, at present, the prefabricated wall generally adopts a sandwich structure. This structure is to connect the 5-8cm thick concrete plate on the outside of the insulation board with the concrete of the main structure through the connector passing through the insulation board. The sandwich structure There are cumbersome production, high cost, and low safety system. There is no implementation standard for the connectors used to fix the outer 5-8cm thick concrete slab, the quality is difficult to guarantee, and a large number of cold bridges are formed. At present, all rely on imports, and the cost is high. No less, it is difficult to promote the current prefabricated buildings, and the incremental cost remains high
