S-lap-joint-type-waterproof-cover-combined roof rainwater flow guide device with silencing function and buffering function

Abstract

The invention discloses an S-lap-joint-type-waterproof-cover-combined roof rainwater flow guide device with the silencing function and the buffering function. The waterproof cover can effectively prevent rainwater from permeating into a structural plate of a roof and connecting gaps between the roof and walls of a house. The waterproof cover is spliced by a plurality of aluminum-plastic plates, and the processing difficulty of the waterproof cover can be reduced. The edges of the opposite ends of every two adjacent aluminum-plastic plates are processed to be in an S shape, and are in lap joint in a matched mode. By means of a flow guide groove, it is prevented that rainwater directly scours the walls, the walls are corroded and damaged, and even rain leakage occurs. The side wall of the outer side of the flow guide groove is in an arc shape, splashed rainwater can be better guided to fall back into the flow guide groove, and impacting of rainwater of the flow guide groove is reduced. The portion between the double pipe walls of a flow guide pipe is divided into a plurality of closed small spaces, the small spaces are filled with energy absorption balls, energy of vibration of sound waves is absorbed, and noise is eliminated. Protrusions are arranged on the inner side of the inner pipe wall, the rainwater scouring speed is decreased, sounds generated by pipe wall impacting are reduced, and the effect of eliminating noise is achieved.

Description

technical field [0001] The invention belongs to the technical field of waterproofing of modular houses, and in particular relates to a roof rainwater diversion device combined with the sound-absorbing and buffering function of an S lap-jointed waterproof cover. Background technique [0002] With the rapid development of society in recent years and the improvement of people's living standards, architecture is also quietly changing. [0003] People's requirements for architecture are not only to provide a place to live, but also to pay more attention to the overall structural performance of the house. Modular building is the mainstream of building development, and it is more and more favored by people because of its superior performance. [0004] The direction of building modularization is to use designed building components to be manufactured in a factory environment, and then transported to the construction site for installation. It generally includes a steel structure fra...
