Construction method of steel structure roof waterproof and heat insulation system

Abstract

The invention relates to a construction method of a steel structure roof waterproof and heat insulation system. The method comprises the following steps: after a profiled steel plate is mounted, a polyethylene PE film steam separation layer is paved on the profiled steel plate; a glass wool plate is fixed on a PE film by a self-tapping screw and a sleeve; finally, a PVC (Polyvinyl Chloride) waterproof roll is paved on the glass wool plate; a lamp joint of the PVC waterproof roll adopts a hot air welding manner and the material of the lamp joint is a base material, namely PVC which is connected by welding is a whole material without a connector; the joint formed by the process and the base material can be integrally formed and are firm and reliable; a formed roof is an integrated whole body and a partially weak phenomenon and the like do not exist. The main construction method comprises the following steps: construction preparation, base layer treatment, pavement of the PE film, pavement and fixation of a heat insulation layer, pavement and fixation of the PVC roll, treatment of thin part nodes and inspection and acceptance.

Description

technical field [0001] The invention relates to roof waterproof and thermal insulation construction, in particular to a construction method for a steel structure roof waterproof and thermal insulation system. Background technique [0002] In the prior art, the roof of the steel structure generally adopts the color plate roof, which results in serious water seepage of the structural workshop and many quality defects. [0003] The above-mentioned ordinary waterproof and thermal insulation methods can no longer meet the construction quality and construction period requirements of large-scale steel structure roof waterproof and thermal insulation in the prior art. It is urgent to develop a new waterproof and thermal insulation construction method to meet the needs of the scale of existing steel structure buildings. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a construction method of a complete waterproof and ther...
