Roof construction method of broken bridge waterproof roof gutter spout funnel

Abstract

The invention discloses a roof construction method of a broken bridge waterproof roof gutter spout funnel. The roof construction method includes the following steps that a water stop ring on an outerbarrel of the gutter spout funnel is pre-embedded in a concrete layer when a roof reinforced concrete floor slab is poured; a first leveling layer, a vapor barrier layer, a heat insulating layer, a slope making layer and a second leveling layer are laid successively on the concrete layer; a coiled material layer is laid on the second leveling layer, the tail end of the coiled material layer is putinto a water stop groove of the outer barrel, and then the water stop groove is filled with waterproof glue; a waterproof layer and a coiled material protective layer are laid successively on the coiled material layer; and the gutter spout funnel is inserted into the outer barrel pre-embedded in the concrete layer through an inner barrel. According to the roof construction method of the broken bridge waterproof roof gutter spout funnel, the waterproof effect is good.

Description

technical field [0001] The invention relates to the field of roof waterproofing, and more specifically relates to a roof construction method for a waterproof roof drop bucket on a broken bridge. 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. The length of the downspout is not enough to cause hanging feet, and the drain pipe is directly connecte...

[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. The length of the downspout is not enough to cause hanging feet, and the drain pipe is directly connected to the outside. The temperature difference between the indoor and outdoor cold bridges will condense and produce condensed water. The root of the downspout absorbs water to form a false leak.
