Description

Roof rainwater collecting port structure

Technical Field

The utility model relates to a construction field, concretely relates to rain water discharging equipment's of building roofing rainwater collection mouth structure.

Background

The main task of roof drainage design is to divide the roof into a plurality of drainage areas, and then guide the rainwater to respective downpipes and then drain the rainwater to the ground through appropriate drainage slopes and drainage ditches. The method comprises the following specific steps: (1) determining a forming method and gradient magnitude of a roof gradient; (2) selecting a drainage mode and dividing a drainage area; (3) determining the section form and size of the gutter; (4) determining the material, size and spacing of the downpipe, and drawing a roof drainage plan. The width of the roof with single-slope drainage is not more than 12m, the clear width of the rectangular gutter is not less than 200mm, and the distance from the highest position of a longitudinal slope of the gutter to the upper opening of the gutter is not less than 120 mm. The inner diameter of the downpipe is not smaller than 75mm, the space between the downpipes is generally 18 m-24 m, and each downpipe can drain about 200 square meters of roof rainwater. The water-proof professional standard is that each downpipe can discharge about 250 square meters of roof catchment area (catchment area includes the wall surface area of the roof). The prior art is scientific for the roof waterproof standard, but in actual construction, water in a roof drainage area is drained to the ground or a sewer pipeline through a drainage collecting pipe, and the problem of rainwater gathering or leakage often occurs at the position of a collecting port of a drainage pipe.

SUMMERY OF THE UTILITY MODEL

The utility model provides a mouth structure is collected to roofing rainwater, the problem of rainwater gathering or seepage can often appear in the collection mouth department that it had solved the roofing drain pipe.

In order to solve the above problem, the utility model adopts the following technical scheme: the roof rainwater collecting port structure comprises a roof 1, a parapet wall 2 is arranged on the periphery of the outer side of the roof 1, and a drainage pipeline is arranged below the parapet wall 2; the drainage pipeline comprises a rainwater collector 3 and a drainage pipe 4, the rainwater collector 3 is in a quadrangular frustum pyramid shape with two open ends, the drainage pipe 4 is composed of a transverse pipe and a vertical pipe, and the end of the horizontal pipe of the drainage pipe 4 is welded with the small end of the rainwater collector 3; the horizontal pipes of the drain pipes 4 and the rainwater collectors 3 are arranged below the parapet wall 2 and in the holes, and the horizontal pipes are arranged in a gradient manner with the inner part higher and the outer part lower by 2 percent; the big end of the rainwater collector 3 is positioned on the inner side surface of the parapet wall 2; have polyurethane waterproofing membrane 8 above roofing waterproofing membrane 7, polyurethane waterproofing membrane 8 extends to downside in rainwater collector 3 and to drain pipe 4 border position, and polyurethane waterproofing membrane 8 surface forms the 2% slope of height outside high.

Further, heat preservation rock wool 5 is filled around rainwater collector 3 and the pipe is violently managed to drain pipe 4, is provided with sealed glue 6 between hole port and the 3 open ends of rainwater collector.

Further, the edge of the waterproof coiled material 7 on the roof 1 is pasted and paved on the edge of the lower side surface of the port of the rainwater collector 3 and is adhered with the sealant 6.

The utility model discloses the advantage:

1. the rainwater collector in the shape of the quadrangular frustum pyramid is adopted, the large opening end of the rainwater collector can collect rainwater more easily, and drainage is facilitated.

2. Polyurethane waterproofing coating layer on aspect waterproofing membrane extends to in the rainwater collector lower surface for form the slope inclined plane of extension with the roofing below the rainwater collector, can not cause the gathering of rainwater.

3. The edge of the waterproof coiled material of the roof is paved to the edge of the lower side surface of the port of the rainwater collector and is bonded through the sealant, so that the waterproof and prevention performances are improved.

4. The gradient of the transverse pipe of the drainage pipeline is smoothly extended with the gradient of the roof waterproof coating, and the drainage performance reaches the best.
