Broken bridge water-proof roof gutter spout funnel

Abstract

The invention discloses a broken bridge water-proof roof gutter spout funnel. The broken bridge water-proof roof gutter spout funnel comprises an outer barrel, a water-proof cover, and an inner barrel, wherein the outer barrel is pre-buried in a structural layer, the water-proof cover is used for overlapping coiled materials, and the inner barrel is suitable for variety of the thicknesses of the structural layer, a water stopping groove is formed in the side wall of the circumference of the outer barrel, annular hot melt adhesive is arranged at the bottom of the water-proof cover, the hot meltadhesive is internally provided with a resistance wire, the hot melt adhesive is arranged in the water stopping groove, the inner barrel is arranged in the outer barrel in an inserting mode, and thetop of the inner barrel is connected with a water diversion cover and a strainer. The broken bridge water-proof roof gutter spout funnel is convenient to operate and good in water-proof effect.

Description

technical field [0001] The invention relates to the field of construction engineering, and more specifically relates to a broken bridge waterproof roof drain bucket. Background technique [0002] At present, the roof leakage of construction projects is a common quality problem in national projects. There have been no good measures to solve it for many years, which shortens the service life of normal buildings. It did not take into account the closed combination of the flat coiled material and the fan-shaped coiled material of the drain, making it a weak link for waterproofing, nor did it take into account the influence of the thickness of the roof structure layer, leveling layer, slope layer, and insulation layer, resulting in the protection of the coiled material layer. There is only one simple caulking with the flange ring for waterproofing, and the length of the sink is not long enough to cause hanging feet, and the drain pipe is directly connected to the outside, the tem...

[0002] At present, the roof leakage of construction projects is a common quality problem in national projects. There have been no good measures to solve it for many years, which shortens the service life of normal buildings. It did not take into account the closed combination of the flat coiled material and the fan-shaped coiled material of the drain, making it a weak link for waterproofing, nor did it take into account the influence of the thickness of the roof structure layer, leveling layer, slope layer, and insulation layer, resulting in the protection of the coiled material layer. There is only one simple caulking with the flange ring for waterproofing, and the length of the sink is not long enough to cause hanging feet, and the drain pipe is directly connected to the outside, the temperature difference between the indoor and outdoor cold bridge condensation will produce condensed water, and the roof plate at the root of the sink will absorb water to form a false leak , affecting the use of functions
