Description

A thermal insulation building PC exterior wall

technical field

The utility model relates to the technical field of thermal insulation of PC outer wall buildings, in particular to a thermal insulation type building PC outer wall.

Background technique

At present, most of the new building walls are still constructed by traditional pouring concrete or masonry methods, which have problems such as long construction period, serious construction site pollution, low labor productivity, unstable quality, and large waste and loss.

In modern residential buildings, the trend of modular installation has gradually developed. This kind of modular installation, as the name implies, is to complete the production of various modules in the house, such as bay windows, columns, walls, etc. in the factory, and then transport them to the site for combined installation, which greatly shortens the construction time of the building. The PC used in these modules is precast concrete, also called precast concrete.

The application of prefabricated concrete wall panels can greatly reduce the labor intensity of construction personnel, and the cross operation is convenient and orderly; each process in the assembly can be checked for its accuracy like equipment installation to ensure construction quality and reduce noise during construction. , the material stacking site is reduced, which is conducive to environmental protection; due to the completion of standardized and large-scale production in the factory, the stability of building quality has been improved. In the current production of each module, it is necessary to meet various requirements such as stability, heat preservation and practicality. .

In the traditional building exterior wall structure, the internal insulation method is simply to bury the insulation sheet made of sponge and other materials in the outer wall concrete, but in the later use of the outer wall, it is easy to cause the deformation of the insulation sheet due to external temperature changes. , which will affect the thermal insulation effect of the external wall. Therefore, many advantages of precast concrete wall panels are unmatched by traditional building construction methods.
