High-pressure load bearing wallboard and preparation method thereof

Abstract

At present, total energy consumption of the buildings tops the list of energy consumption in the country, the proportion of the energy for buildings to the energy consumption of the country is still increasing year by year, and the energy conservation of buildings is one of the key fields for saving energy of the whole society, wherein the energy conservation and heat insulation of the external walls of buildings is one of the important points for energy conservation and consumption reduction of the buildings at present. The invention provides a high-pressure load bearing wallboard which comprises a decoration layer on outer surface, a protection layer composed of alkali-resistant grid cloth, a heat insulation layer and a concrete structure layer, wherein the decoration layer is composed of decorative finish mortar; and the concrete structure layer is composed of prefabricated reinforced concrete.

Description

technical field [0001] The invention relates to building enclosure structures in the technical field of building energy conservation, in particular to a high-pressure load-bearing wallboard and a preparation method thereof. Background technique [0002] At present, the total energy consumption of buildings in my country ranks first in energy consumption, and the proportion of building energy consumption in my country's energy consumption is still increasing year by year. Building energy conservation has become one of the key areas of energy conservation in the whole society. One of the key points of energy saving and consumption reduction. There are mainly three energy-saving methods of the existing building envelope structure, three methods of external wall internal insulation, external wall internal insulation and sandwich insulation. These three insulation methods have their own advantages and disadvantages. The advantage of external wall insulation is that it can effecti...

AI Technical Summary

Problems solved by technology

These three insulation methods have their own advantages and disadvantages. The advantage of external wall insulation is that it can effectively avoid the generation of cold and heat bridges and effectively protect the main structure. However, its disadvantage is that the widely used organic insulation boards have relatively poor fire performance. , and its construction is relatively difficult; the advantage of internal insulation of the external wall is that the construction is relatively simple and the cost is low, but its disadvantages are also obvious. It is difficult to avoid the generation of cold and thermal bridges by adopting the method of internal thermal insulation of the external wall. The junction of layers is prone to condensation, mildew, etc.; the advantage of sandwich insulation is that it has lower requirements for insulation materials, especially the strength of insulation materials. The disadvantage is that the generation of cold and heat bridges cannot be avoided, and construction is difficult.
