AI Technical Summary

Problems solved by technology

[0003] 1. The prefabricated wall structure of concrete external wall panels is complex, heavy, unfavorable for earthquake resistance, high in cost, and requires a lot of land and formwork during prefabrication. Prefabrication and installation are inconvenient, and there are many thermal bridges, making it difficult to build low-energy buildings.

[0004] 2. Many prefabricated walls generally have the problem of many thermal bridges, poor energy saving and heat preservation

[0005] 3. The joint problem of the prefabricated wall panel of the prefabricated wall has not been solved

There is a project with this structure in Harbin. In winter, the joints are cold, ventilated, dew-condensed, and the indoor walls are dripping, moldy, and hairy, and cause the wooden floor to warp. Affect the durability of the wall and affect the comfort of living

This situation leads to the fear of adopting prefabricated thermal insulation walls in severe cold areas, which affects the process of residential industrialization and building energy conservation.

Or some use a prefabricated wall, and the outside is decorated with PVC plastic gussets or metal gussets to cover the gaps. Although no cracks can be seen, thermal bridges still exist at the joints, and there are hidden dangers of cold and ventilation at the joints. Still, the corrosion problem of steel columns and steel beams at the joints still exists

[0006] 4. There are frequent earthquakes in my country and the world, and the proportion of high-rise buildings in my country is very large. The existing prefabricated wall structure that adapts to the deformation of the main structure of the building is too complicated and expensive

Such as 1), Yu Yan's article "The connection structure of Japanese building wall panels", from the article and the accompanying drawings, it can be seen that the seismic structure of Japan's slidable prefabricated walls is too complicated

2), also like 08SJ110-2 and 08SG333 in the architectural standard design atlas "Prefabricated Concrete External Wall Panels". It can be seen from the drawings and descriptions that the structure of the slidable prefabricated wall is too complicated, and it is difficult to process prefabricated insulation panels. High difficulty, large amount of steel bars, heavy weight, large prefabrication area occupation, and high cost are not conducive to the popularization of prefabricated walls, and affect the safety of buildings against earthquakes and lateral movement of high-rise buildings

[0007] Traditional aerated concrete walls are built with aerated concrete blocks and then plastered, or for the installation of internal reinforcement aerated concrete wall panels and then plastered. Even if it is used in the south, the surface plaster is easy to bulge, crack, fall off, and seep. Quality problems such as leakage and cracking of joints, many wet operations on site, many thermal bridges, need to use thermal insulation mortar for insulation, and the earthquake resistance is not good

Air-entrained concrete has a high thermal conductivity and is not suitable for low-energy building applications in heating areas, especially not suitable for building energy conservation requirements in severe cold areas
