Description

Concrete load-bearing insulation board

technical field

The utility model belongs to the technical field of buildings, in particular to a concrete load-bearing and thermal insulation integrated board.

Background technique

The industrialization of prefabricated buildings, housing industrialization and urbanization require active promotion of prefabricated buildings. The key indicator for assessing the level of building industrialization is the degree of assembly of exterior walls. The promotion and application of prefabricated lightweight concrete exterior wall panels is in line with the national industrial policy of green buildings and building energy conservation, and is an important part of the sustainable development strategy of the construction industry. As an excellent product for energy-saving and thermal insulation of building exterior walls, thermal insulation and decorative integrated panels, how to combine with prefabricated buildings is an important issue for prefabricated buildings.

The prefabricated composite wall panels in foreign countries were mainly developed after 70 years. The light-weight wallboard in the United States is mainly made of various gypsum boards. It is famous for its variety, complete specifications and high degree of production mechanization. The annual output is 2 billion square meters, ranking first in the world. The production of Japanese asbestos cement boards, autoclaved Guihan boards, and glass fiber reinforced cement boards (GRC boards) ranks at the leading level in the world. The UK mainly uses asbestos-free osmanthus Korean board. Germany and Finland mainly produce hollow lightweight concrete wall panels. For a long time, the prefabricated houses have mainly formed the FCIS wall system of the Csatel Eiffle residential complex in Dijon, France, the BSAIS industrial building exterior wall system in Italy, and the PCa wall panel system used in the walls of high-rise steel structure houses in Japan. Development status and performance comparison of domestic prefabricated exterior wall panels Building exterior walls are the main components of buildings, and their structure and materials used affect building energy consumption indicators and indoor living comfort. In the energy consumption of the enclosure structure of residential buildings: 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.

The production of wall panels and wall materials in some developed countries has accounted for as high as 60% of the total output of wall materials in their countries, while our country only accounts for 3%. In terms of the exterior wall structure of buildings, my country is vigorously encouraging the development of green building materials, 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 on wind resistance, earthquake resistance, etc., deduced Some specific theories and formulas, but the research results about composite wall panels are not deep and comprehensive enough. The main problems are as follows: most sandwich composite wall panels use ordinary concrete as the structural layer, and light bone There are relatively few studies on concrete as a surface layer, and there is a lack of literature related to the research on the point-supported flexural load-bearing performance of composite wall panels, and the basic mechanical indicators of the structural layer required for the basic installation and use of wall panels are not clear. 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 the good thermal insulation performance of lightweight aggregate concrete materials requires further development. Improving the strength of lightweight aggregate concrete has become a subject of research and discussion. The basis and advantage of energy-saving composite wall panels are their superior thermal insulation performance, but there is a lack of research on the relevant thermal performance indicators and the node structure of energy-saving composite wall panels, so it is necessary to choose a scientific node installation method. It can not only ensure excellent heat transfer performance, but also achieve the basic mechanical performance indicators required by itself.

In recent years, smog has begun to wreak havoc across the country. With the rapid development of my country's economy, problems such as energy consumption and environmental pollution have become increasingly prominent. The air quality is getting worse and worse, and people's demand for environmental protection is becoming more and more urgent. For the construction industry with huge energy consumption, it is urgent to develop green and energy-saving buildings.

The relationship between prefabricated buildings and green buildings, one is an important carrier of construction industrialization, and the other is the overall direction of construction development. On the road of exploring and refreshing the application value of building materials, the two should be combined, and the thermal insulation and decoration integrated board should be used as the starting point. From production to installation to operation, the green concept of low emission and low energy consumption should be implemented.

Production: The thermal insulation and decoration integrated board is completed on the automatic assembly line through modern production technology and equipment, and has the characteristics of integration and modularization.

Construction: The thermal insulation and decoration integrated board has been prefabricated in the factory, which is convenient and fast to install during construction, reducing environmental pollution on the construction site.

Energy saving: In addition to the energy-saving performance of thermal insulation materials, the unique structure of thermal insulation bridge and special ventilation device have independent breathing function and comfortable living.

Maintenance: The thermal insulation and decoration integrated board has a stable chemical and physical structure, will not decompose and mildew, has no radiation, no pollution, and is green and environmentally friendly. The thermal insulation and decoration integrated board can be disassembled and reinstalled flexibly, easy to clean, durable and has a long service life.

Refreshing the green productivity of buildings requires the joint promotion of the entire industrial chain. Explore trends and innovate the application of environmentally friendly and energy-saving materials.
