High-protruding object periphery waterproof treatment device and method for steel structure roof

Abstract

The invention discloses a high-protruding object periphery waterproof treatment device and method for a steel structure roof and belongs to the technical field of house water proofing. A waterproof structure comprises a gutter, a downpipe, waterproof closing edges and a waterproof plug. The gutter is an internal wall type gutter, is installed between a roof high-protruding object and a roof face plate and is made by welding a galvanized iron sheet, the cross section of the gutter is U-shaped, the gutter is transversely arranged in the side direction of a house ridge, flanges on the left and right sides of the gutter are respectively fixed to a roof high-protruding object wall face plate and the roof face plate, the gutter is utilized to collect rainwater from the house roof, the downpipe is utilized to drain water to the ground, it can be completely avoided that rainwater is accumulated to form huge water flow, the huge water flow is prevented from spilling over wave crests of the roofface plate to cause water leakage at lock catch positions of the roof face plate, meanwhile another three roof face plates at the bottom of the high-protruding object all adopt closing edges to serveas high-low-span flashing structures, a very good waterproof effect is played, and the applicability of the steel structure house is improved to some degree.

Description

technical field [0001] The invention relates to the technical field of house waterproofing, in particular to a device and method for waterproofing the periphery of high protrusions on a steel structure roof. Background technique [0002] When traditional waterproofing methods and devices are applied to the surrounding structures of steel structure roof overhangs, there are the following deficiencies: [0003] 1. The traditional waterproofing method usually adopts a herringbone-shaped shunt water retaining bar on the bottom roof of the high protrusion facing the slope of the roof to divert the water from the slope of the roof to avoid water leakage on the bottom roof of the high protrusion. However, in the heavy rain season, the rainwater will pass through The herringbone diverter water retaining strips form a huge water flow over the peaks of the roof tiles on both sides of the bottom of the high protrusion, and through the cracks at the connection position between the herri...

Problems solved by technology

[0003] 1. The traditional waterproofing method usually adopts a herringbone-shaped shunt water retaining bar on the bottom roof of the high protrusion facing the slope of the roof to divert the water from the slope of the roof to avoid water leakage on the bottom roof of the high protrusion. However, in the heavy rain season, the rainwater will pass through The herringbone diverter water retaining strips form a huge water flow over the peaks of the roof tiles on both sides of the bottom of the high protrusion, and through the cracks at the connection position between the herringbone diverter water retaining strips and the roof panel locks, resulting in large-scale water leakage;

[0004] 2. When the traditional waterproof method is used for lateral waterproofing of high protrusions, sealing paste is used to seal the roof tiles on the joints of the roof panels on both sides of the bottom of the high protrusions to form a closed roof to prevent flooding of the joints of the roof panels. After the steel structure roof has undergone one or two years of drastic temperature changes in summer and winter, the roof tiles will expand with heat and contract with cold, and the masonry mortar and locking sealant will inevitably produce cracks, with short effective service life and poor waterproof performance;

The waterproof method in the prior art is greatly affected by the environment, limited by seasonal temperature difference changes and rainfall, which often leads to structural damage and rainwater accumulation, resulting in large-scale water leakage on the roof. Its scope of application is limited, and to a certain extent The applicability of steel structure houses
