Method for mounting ALC plate wall with post-applied prestress

Abstract

The invention relates to a method for mounting an ALC plate wall with post-applied prestress, which comprises the following steps of: S1, a plurality of vertical positioning steel bars on a structural beam can be pre-buried; prestressed steel bars are fixedly installed on the structural columns; S2, through holes are formed in the side faces of the ALC plates, the prestressed steel bars penetrate through the through holes, and the positioning steel bars are located in abutted seam holes formed between every two adjacent ALC plates; S3, when the window is mounted, the prestressed steel bars are sleeved with steel pipes, driven into the ALC plates, and nuts are screwed; S4, the other side is installed in the same mode; S5, the ALC plate below the window is started to be installed, and the height of the positioning steel bars is larger than that of the ALC plate below the window; S6, concrete is injected into the abutted seam holes in the two sides of each plate; and S7, a pressing plate is installed on the upper end face of the ALC plate below the window, and then a steel bar head higher than the pressing plate is cut off. The wall body manufactured through the method has the advantages of being high in integrity and convenient and fast to assemble.

Description

technical field [0001] The invention relates to the field of building structure installation, in particular to a method for installing an ALC plate wall after prestressing. Background technique [0002] With the country's admiration for green buildings, ALC panels, that is, autoclaved aerated concrete panels, are becoming more and more common as interior and exterior wall panels. The existing ALC panel installation methods can be summarized into two categories. The first category is to install the panels one by one on site, and the panels are connected by adhesives. Since the panels are installed separately, relying solely on Adhesives are difficult to connect multiple boards into a whole wall, so this installation method has certain defects in grasping the integrity of the wall; the second type of installation method is to directly use the pre-installation method to prestress the combined large boards , that is, in the early stage of construction, according to the design s...
