Background

China is a country with high energy consumption, the building energy consumption accounts for about 30 percent of the total energy consumption, and the building envelope structure not only accounts for the high proportion of the building energy consumption, but also directly influences the heat insulation performance of the building structure. With the continuous high standard and high requirement of China on the heat insulation performance of building structures, China is vigorously developing housing industrialization in order to realize energy conservation and emission reduction. At present, the inner partition wall adopts more precast concrete sandwich heat-insulation wall bodies, so that heat insulation of a building can be realized, and the self weight of the structure can be reduced. However, the prefabricated partition wall cannot continuously preserve heat at the concrete beam position, and in order to ensure the continuity of heat preservation and heat insulation, an insulating layer needs to be arranged on the side surface of the beam at a later stage. Not only increases the workload of decoration, but also has certain influence on the heat preservation and insulation effect of the wall body.

In order to solve the problems, the connection method of the top of the prefabricated partition wall and the position of the cast-in-place concrete beam is urgently needed to be developed, so that the prefabricated partition wall can meet the development requirements of housing industrialization, the workload of later-stage decoration and finishing can be reduced, and a good heat preservation and insulation effect is realized.
