Description

Roof drain port waterproof structure

Technical Field

The utility model relates to a waterproof field of building, concretely relates to roofing mouth of falling into water waterproof construction.

Background

For collecting and discharging the rainwater, the building roof all is equipped with drainage structures, and the rainwater that falls to the roof collects the roof ditch with the rainwater through looking for the slope of roof, and the ditch collects the rainwater mouth with the rainwater, and the rainwater is annotated the downspout through the downspout, and the rethread downspout is arranged the rainwater to appointed outlet.

In the construction process, due to the reasons of environment, human factors and the like, particularly under the condition of wet operation, moisture exists between the roof heat-insulating layer and the waterproof layer after the construction is finished, and the moisture is evaporated under the influence of climate and temperature, but is always sealed in the roof waterproof layer and cannot be released. After long-term accumulation, moisture can be released through a part with relatively weak sealing performance (usually, a part close to a parapet wall), so that the phenomena of dampness, mildew, alkali return and the like are generated on the outer surface of the moisture-releasing part, and the indoor surface layer is expanded and has cracking risk. In addition, if the existing rainwater pipe is difficult to discharge in a short time in heavy rain, the problem of unsmooth drainage occurs.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide one kind can be drawn forth the aqueous vapor of heat preservation, prevent that the roofing surface course from bulging and fracture and can effectively promote a roofing water outlet waterproof construction to the rainwater discharge amount.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a roof drain port waterproof structure comprises a roof structure layer and a parapet wall vertically arranged on one side of the roof structure layer, wherein a first drain port is formed in the parapet wall, a drain pipe is arranged at the first drain port, one end of the drain pipe is fixed in the first drain port, and the other end of the drain pipe extends downwards to lead rainwater out of a roof; the roof structure layer comprises a structure plate, a waterproof layer, a heat preservation layer and a rigid concrete roof layer which are arranged from bottom to top, a first water filter pipe with the upper end flush with the rigid concrete roof layer and the lower end extending to the position of the heat preservation layer close to the waterproof layer is vertically arranged close to a first water falling port, a third water falling port is transversely arranged on the parapet wall close to the upper end of the waterproof layer, a second water filter pipe communicated with the lower end of the first water filter pipe and a water inlet of the third water falling port is transversely arranged on the waterproof layer and in the heat preservation layer, a plurality of rows of water filter holes are circumferentially arranged on the first water filter pipe and the second water filter pipe, and a water permeable layer is wrapped on each of the first water filter pipe and the second water filter pipe; the water outlet of the third water falling port is communicated with the water falling pipe through a transverse connecting pipe, and impurity filtering discs are arranged at the water inlets of the first water falling port, the third water falling port and the second water filtering pipe. Like this, through add the first strainer of vertical setting and the second strainer of horizontal setting at the heat preservation, and add the third mouth of a water in the first mouth of a water lower extreme, and simultaneously, first strainer, second strainer and third mouth of a water communicate each other, thereby can be effectively with the steam of heat preservation through first strainer and second strainer water conservancy diversion to third mouth of a water in the water, and in introducing these steam into the pipe of falling water through horizontal connecting pipe, can avoid the heat preservation to lead to the phenomenon that the roofing bloated and ftractures because of long-term overstock steam effectively. In addition, the upper end UNICOM of first strainer is close to first water outlet department to the roofing to can shunt the rainwater, prevent to dredge not smooth problem because of the rainwater appears when the rainfall is too big.

Furthermore, the rigid concrete roof layer has a gradient of 2% -3.5% near the parapet wall, and the position near the parapet wall is lower than the middle position of the rigid concrete roof layer. Therefore, under the slope, the rainwater can be quickly guided to flow to the first water falling port and the first water filter pipe, and the diversion of the rainwater is accelerated.

Further, the water permeable layer is a water permeable non-woven fabric. Like this, the non-woven fabrics cost is low, and has good water permeability, simultaneously, can also play filterable effect.

Furthermore, the impurity filtering disc is a filter screen or a rainwater grate. Like this, two kinds of filterable structures are all comparatively simple, and the operability is high, simple to operate.

Furthermore, one side of the waterproof layer, which is close to the parapet wall, extends upwards along the parapet wall and is embedded into the parapet wall at a position higher than the first water falling port. Therefore, even if the rainwater is large, the lower end of the parapet wall can not lead accumulated water into the structural layer through the parapet wall due to the soaking of the rainwater.

Furthermore, a clamping groove is formed in the parapet wall and above the first water falling port, and the outer edge of the waterproof layer is fixed in the clamping groove through ointment. Therefore, the outer edge of the waterproof layer is fixed through the factice, and the fixing operation is simple.

Furthermore, the transverse connecting pipe is obliquely arranged, and one end of the transverse connecting pipe close to the downpipe is lower than the other end of the transverse connecting pipe. Therefore, when accumulated water passes through the second water filtering pipe and the third water falling port, the water can quickly flow into the water falling pipe under the action of gravity and is discharged through the water falling pipe.

Furthermore, a second water falling port for assembling the first water filtering pipe is arranged at a position close to the first water falling port. Therefore, the first water filter pipe is convenient to assemble during operation.
