Abstract:
The reinforcement of aluminum alloy formwork is divided into screw system and pull piecesystem. The screw system reinforces the wall and column formwork through the through-wall screw, nutand steel pipe back corrugated. The pull piece system does not need to be drilled, and there is no hole inthe wall after the formwork is removed, which significantly reduces the risk of leakage of the externalwall, and has good construction quality, high installation efficiency and low cost. Combined withengineering examples, compared with the traditional bolt system, it is pointed out that the aluminum alloyformwork pull piece system has the advantages of excellent construction quality, high installationefficiency and small formwork damage in super high-rise residential buildings. Aiming at the durabilityproblem of easy corrosion of the pull piece, the solution is given according to the national waterproofspecification, and specific suggestions are put forward for type selection, installation and quality control.
