Precast concrete sandwiched heat-insulation external wall

Abstract

The invention aims to provide a precast concrete sandwiched heat-insulation external wall, which can meet various structural systems. The precast concrete sandwiched heat-insulation external wall for realizing the purpose is characterized by comprising an outer side precast concrete plate, heat-insulation waterproof mortar, overlapped ribs, an inner side precast concrete plate and a connecting part used for being connected with a main body structure, the heat-insulation waterproof mortar and the overlapped ribs are arranged between the outer side precast concrete plate and the inner side precast concrete plate, and the overlapped ribs are connected with the inner side precast reinforcement concrete plate and the outer side precast reinforcement concrete plate in a pulled manner, and are sealed in the heat-insulation waterproof mortar.

Description

technical field [0001] The invention relates to thermal insulation walls, in particular to wall components suitable for industrialized residential construction methods. Background technique [0002] China's urbanization process is rapid, and the rapidly growing demand for housing has stimulated the rapid development of the housing industry. Our country has a large low-cost labor force, which has fueled the growth of construction companies and created serious problems. Due to the difficult working environment in the construction industry, construction personnel entering the construction industry are relatively low-quality, highly mobile, and lack of training. If you want to ensure the quality of the project, the management cost is very high, and even uncontrollable. In the absence of high-quality construction personnel, how to ensure the quality of the project, not only to meet the rapidly expanding housing market demand, but also to ensure high-quality housing construction ...

Problems solved by technology

[0003] A variety of lightweight composite wall panels have been developed in China, such as the application number 01128617.2 lightweight composite wall core board. Difficult, such as the patent No. 92221294.5 stencil hollow foam composite board, the patent No. 93235378.9 composite lightweight wall board, as the outer wall has the above problems, at the same time, the temperature stress deformation and interlayer displacement will cause cracks and waterproof problems in the outer wall

There are also applications of prefabricated concrete sandwich insulation exterior walls in China, but the waterproof aging of the sandwich insulation layer has not been considered, resulting in durability problems. Therefore, an energy-saving and environmentally friendly prefabricated concrete sandwich that can meet various structural systems has been developed. Insulation exterior wall is the need of the development of the times
