Prefabricated aerated concrete wall panel with decorative panel and installation method of its decorative panel

technical field

The invention belongs to the technical field of construction, and in particular relates to an assembled aerated concrete wall panel with a decorative panel and an installation method for the decorative panel.

Background technique

At present, my country is in the rapid process of urbanization. By 2020, it will achieve "all-round well-off", the urbanization level will reach about 60%, the urban population will increase by about 300 million, and the number of urbanized housing construction will remain at a relatively high level for a long time . Promoting the industrialization of construction and housing construction is a major measure to realize the transformation of housing construction from extensive to intensive, improve housing quality and save housing energy consumption, and is an important way to ensure the sustainable development of the construction industry. Development has extremely far-reaching meanings.

Construction industrialization, housing industrialization, and urbanization require active promotion of prefabricated construction. In the enclosure structure, the key indicator for assessing the level of building industrialization is the degree of assembly of the outer walls.

Research status of foreign prefabricated composite wallboards: Foreign prefabricated composite wallboards were mainly developed after 70 years. The light-weight wallboards in the United States are mainly made of various gypsum boards, with many varieties, complete specifications, and the degree of production mechanization. It is famous for its high quality, with an annual output of 2 billion square meters, ranking first in the world; Japan's production of asbestos cement board, autoclaved Guihan board, and glass fiber reinforced cement board (GRC board) ranks at the leading level in the world; Britain's asbestos-free Guihan board is the leading Mainly; Germany and Finland mainly produce hollow lightweight concrete wall panels. For a long time, foreign countries have mainly formed the FCIS wall system of the Csatel Eiffle residential complex in Dijon, France, the Italian BSAIS industrial building exterior wall system, and the PCa wall panel system used in Japanese high-rise steel structure residential walls.

Development status and performance comparison of domestic prefabricated exterior wall panels: The exterior wall of a building is the main component of a building, and its structure and materials used affect building energy consumption indicators and indoor living comfort. In residential buildings, the energy consumption of the envelope structure: the outer wall can account for 34%, and the stair partition wall accounts for about 11%. The development of high-quality composite thermal insulation wall panels for exterior walls is an important shortcut to realize the industrialization of housing and promote energy-saving buildings. In terms of the exterior wall structure of buildings, my country is vigorously encouraging the development of green building materials, vigorously promoting various non-clay brick, light, large-size wall materials, and further improving the productivity of widely used green exterior wall insulation materials.

At present, the main types of wall panels that can be used as prefabricated external wall panels in China are: load-bearing concrete rock wool composite external wall panels, thin-walled concrete rock wool composite external wall panels, concrete polystyrene composite external wall panels, and concrete perlite composite external wall panels. Wall panels, steel mesh cement insulation sandwich panels, SP prestressed hollow panels, aerated concrete exterior wall panels and vacuum extrusion fiber cement panels (ECP for short).

Prefabricated energy-saving composite wall panels have been applied and promoted because of their excellent characteristics, especially good thermal insulation performance, and a lot of research has been done on the performance of composite wall panels at home and abroad, including wind resistance and earthquake resistance. Some specific theories and formulas, but the research results on composite wall panels are not deep and comprehensive enough, the main problems are as follows:

1. Most sandwich composite wall panels use ordinary concrete as the structural layer, while there are relatively few studies on lightweight aggregate concrete as the surface layer. There is a lack of literature on the point-supported flexural load-bearing performance of composite wall panels, and The basic mechanical indicators of the structural layer required to complete the basic installation and use of wall panels are not clear.

2. Lightweight aggregate concrete has a certain thermal insulation effect in energy-saving composite wall panels, but the low thermal conductivity of lightweight aggregate is premised on sacrificing its strength. Therefore, how to maintain good thermal insulation performance of lightweight aggregate concrete materials, Further development and improvement of the strength of lightweight aggregate concrete has become a subject of research and discussion.

3. The basis and advantage of the promotion of energy-saving composite wall panels is its own superior thermal insulation performance, but there is a lack of research between the relevant thermal performance indicators and the node structure of energy-saving composite wall panels, so it is necessary to choose a scientific node The installation method can not only ensure excellent heat transfer performance, but also achieve the basic mechanical performance indicators required by itself.

4. From the research status at home and abroad, it can be known that if the existing wallboard materials are converted into a wall thickness of 150mm, their heat transfer coefficients are generally above 1.3W/(㎡·K), and even fail to reach the specification limits in some special areas Therefore, it is necessary to develop an energy-saving composite wallboard whose heat transfer coefficient can be lower than 1.3W/(㎡·K), which provides design ideas for the development of energy-saving wallboards with low heat transfer coefficients.

5. The specific thermal insulation and energy-saving effect of energy-saving composite wall panels in the project is not clear. There are few relevant data on energy consumption and energy-saving rate of energy-saving composite wall panels in specific building constructions, and the relationship between heat transfer coefficient and building energy consumption There is a lack of qualitative and quantitative relationships. Therefore, it is necessary to use the corresponding energy consumption evaluation mechanism to judge the superiority of energy-saving composite wall panels.

For the decoration of exterior wall panels, the wet paste method is mostly used. The traditional wet paste process is prone to hollowing, cracking, falling off of the board, whitening and discoloration of the board surface, and the large amount of labor is not conducive to the project. schedule.

At present, the research and development, production and application of domestic prefabricated exterior wall panels have made great progress. With the continuous in-depth research of composite wall panels, the improvement of wall panel design theory, the improvement of wall panel node types, the improvement of wall panel installation technology, and the use of new materials, the application of composite wall panels in engineering will be strongly promoted. Aerated concrete exterior wall panels and extruded cement fiber wall panels have the functions of light weight, high strength, energy saving, fire prevention, waterproof, and structural integration, and will become the direction of current and future promotion and application.
