Roof construction method of broken bridge waterproof roof gutter spout funnel

A construction method and the technology of sinking bucket, which are applied in the direction of roof, roof covering, roof drainage, etc., can solve the problem of not considering the closed combination of flat coil and fan-shaped coil at the sink, shortening the service life of the building, affecting the use function, etc. The problem is to avoid the roof seepage, increase the stroke, and slow down the speed of leakage.

Problems solved by technology

[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. Affect the use of functions

Embodiment Construction

[0022] refer to figure 1 The embodiment of the roof construction method of a broken bridge waterproof roof gutter of the present invention will be further described.

[0023] A roof construction method for the water-repellent roof of a broken bridge. A concrete layer 9 is laid on the roof. Generally, the thickness of the concrete is about 120mm. The ring 10 is pre-embedded in the concrete layer 9; it is poured together with the concrete layer 9. After the strength of the concrete layer 9 is qualified, the first leveling layer 8 is laid on the concrete layer 9. Generally, the thickness of the first leveling layer 8 is 20mm. Left and right, because the surface of the concrete layer 9 is pitted, it is necessary to lay the first leveling layer 8 to make the surface smooth for subsequent construction. After the first leveling layer 8, lay a vapor barrier layer 7 of about 10mm and a heat insulation layer of about 80mm 6. The purpose is to avoid the problem of water seepage in the r...

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...
