Research on Key PC Stair Pre-installation Technology Based on a Stair Installation Combined Support Tool
PC stair is a kind of product of prefabricated components suitable for industrial manufacturing.Based on the self-developed PC stair pre-installation combined support tool,this paper proposes a PC stair pre-installation method,so as to achieve the goal of precise control of the height difference between the stair step and the rest platform.Taking a school project in Yangling as an example,the pre-installation technology is verified and analyzed.The results show that the PC stair pre-installation method can better control the height difference between the stair step and the rest platform,and the difference is controlled at 20±2 mm,thus saving the cost of later repair processing.
