Assembled external wall panel for CF autoclaved porcelain powder aerated concrete shear wall and manufacture method thereof

Abstract

The invention discloses an assembled external wall panel for a CF autoclaved porcelain powder aerated concrete shear wall and a manufacture method thereof, and belongs to the field of construction engineering. The external wall panel comprises a plurality of wall panel bodies, wherein each wall panel body comprises an inner vane board and an outer vane board, each outer vane board is a CF autoclaved porcelain powder aerated concrete panel, and each inner vane board is a reinforced concrete shear wall panel; horizontal reinforcing steel bars are arranged in the horizontal direction of each inner vane board, and vertical reinforcing steel bars are arranged in the vertical direction of each inner vane board; a reinforcing steel bar connecting sleeve is respectively in the inner vane board ofthe lower part of each vertical reinforcing steel bar; a slurry outlet and a grouting hole are respectively formed in upper and lower parts of each reinforcing steel bar connecting sleeve; horizontalseams among the wall panel bodies are rabbets while vertical seams are flat seams; waterproof devices are respectively arranged in the horizontal seams and the vertical seams of each outer vane board;the horizontal seams and the reinforcing steel bar sleeves of each inner vane board are filled with slurry; and vertical connecting parts are arranged in the vertical seams of each inner vane board.The assembled external wall panel has the characteristics of excellent insulating performance, good waterproofing property and durability and the like.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an assembled CF autoclaved porcelain powder aerated concrete shear wall outer wall panel and a manufacturing method thereof. Background technique [0002] In recent years, with the improvement of my country's green construction, energy conservation and emission reduction, and the substantial increase in labor market prices, prefabricated buildings have begun to be vigorously promoted and applied. At present, most of the prefabricated buildings that have been built and are under construction in my country adopt prefabricated concrete shear wall structures. The external wall panels of the prefabricated shear wall structure usually adopt the prefabricated sandwich thermal insulation shear wall external wall panels (commonly known as sandwich wall panels) integrating structure, decoration and heat preservation. The structure of this type of wallboard is the inner leaf board, ...

AI Technical Summary

Problems solved by technology

During the concrete pouring and vibration process of the inner and outer leaf wall panels, it is easy to cause the middle insulation board to be displaced and damaged, resulting in cracks in the insulation board or excessive gaps in the joints of adjacent insulation boards, and the phenomenon of cold and heat bridges is very obvious, resulting in The thermal insulation performance of the prefabricated shear wall external wall panels integrated with structure, decoration and thermal insulation decreases

[0005] (2) Poor waterproof and durability

If the construction quality of the sealant at the joints of the exterior wall panels is poor and the joints crack, or if the sealant fails after the building is used for more than the validity period, the external rainwater can easily enter the insulation layer, causing the middle insulation layer to absorb water and become damp, which seriously reduces the external appearance. Insulation performance and durability of wall panels
