Description
Technical Field
[0001] The utility model relates to the technical field of roof drainage in house construction, in particular to a roof drainage structure in house construction. Background Art
[0002] In construction projects, roof drainage is very important. It can effectively remove rainwater and avoid problems such as water accumulation and leakage on the roof. There are two main types of roof drainage: organized drainage and unorganized drainage.
[0003] Unorganized drainage refers to extending the roof panel outside the wall to form an overhanging eaves, and rainwater drips directly from the eaves to the ground. This method has a simple structure and low cost, but it is easy to wet the walls, doors and windows, so it is only suitable for low-rise buildings (usually two or three floors) or temporary buildings.
[0004] Organized drainage refers to the centralized collection of rainwater through gutters, eaves gutters, downspouts, downspouts and other facilities, and the orderly discharge to designated locations. This method has high drainage efficiency and good prevention and control effects. It is suitable for all types of buildings, especially high-rise buildings, large-span buildings and areas with heavy rainfall.
[0005] Traditional flat-roofed buildings usually adopt an unorganized drainage method because the roof has no slope, that is, drain outlets are set on the eaves. However, this method has poor drainage effect and is prone to water accumulation and leakage on the roof.
[0006] The unorganized drainage method has low drainage efficiency and can easily cause water accumulation on the roof, especially in extreme weather conditions such as heavy rain, which makes roof leaks more likely to occur.
[0007] Moreover, the existing technology usually does not have effective measures to prevent clogging by debris such as mud, leaves, etc., and the drainage pipes are easily clogged, affecting the drainage effect; the traditional roof drainage system is difficult to maintain and the debris in the drainage pipes needs to be cleaned regularly, otherwise it is easy to cause poor drainage.
[0008] How to solve the above problems is the research topic of this program. Utility Model Content
[0009] In order to achieve the above-mentioned purpose of the utility model and to address the above-mentioned technical problems, the utility model provides a roof drainage structure for building construction.
[0010] The technical solution is as follows: it comprises a water collection tank and a drainage tank symmetrically arranged on both sides of the roof, a filter screen is arranged on the top of the water collection tank, a drainage pipe is arranged at the bottom of the drainage tank, the drainage pipe is connected to the inner cavity of the drainage tank, and a backwash unit is arranged on the inner wall of the water collection tank corresponding to the filter screen;
[0011] The backwash unit comprises a water pump and a plurality of nozzles, and the water pump and the nozzles are connected via water pipes.
[0012] The upper surface of the roof is arranged as an inclined surface which is inclined from the middle to the two ends, and two ends of the roof are arranged with inclined surfaces 2 which are inclined from top to bottom.
[0013] A partition is provided between the water collecting trough and the drainage trough, and the top of the partition is fixedly connected to the bottom of the second inclined surface;
[0014] The cavity formed between the partition, the second inclined surface and the wall is the cavity of the drainage trough.
[0015] A guide groove is provided in the middle upper part of the partition plate, which is inclined from the water collecting groove to the lower part of the drainage groove.
[0016] The main body of the filter screen is arranged as a U-shaped groove structure, and transverse connecting plates are arranged at both ends of the top of the U-shaped groove part;
[0017] The bottom of the inclined surface and the top of the partition are both provided with slots, and the connecting plate is fixedly connected to the slots by a plurality of bolts.
[0018] The water pipe is arranged inside the bottom of the inclined surface, and the water outlet of the water pump is connected to the water inlet of the nozzle through the water pipe;

[0020] The drain pipe is fixed on the side wall of the house through a fixing clamp.
[0021] The core of the roof drainage structure of the house construction lies in the sump and drainage trough symmetrically arranged on both sides of the roof, and the backwash unit inside the sump.
[0022] The sump is responsible for collecting part of the rainwater as the water source for the backwash unit, while the drain trough guides the rainwater to the drain pipe for discharge; the symmetrical structure can evenly distribute the rainwater and avoid local water accumulation.
[0023] The filter is installed on the top of the sump to intercept larger particles of impurities such as leaves and debris to prevent them from entering the drainage system and causing blockage.
[0024] Drain pipes carry rainwater away from the outside of the building.
[0025] When impurities are deposited on the filter, the water pump can be started to spray high-pressure water through the nozzle to flush the filter and keep it unobstructed.
[0026] Rainwater flows from the roof into the sump, passes through the filter to intercept impurities, and then flows into the gutter and out through the drain pipe. The backwash unit regularly flushes the filter to maintain its filtering effect.
[0027] The setting of sump and drainage trough can drain rainwater quickly, avoid water accumulation on the roof and improve drainage efficiency.
[0028] The filter can effectively intercept impurities and prevent the drainage system from being blocked.

[0031] The inclined roof structure allows rainwater to flow quickly to the gutter, avoiding water accumulation on the roof and facilitating the discharge of rainwater.
[0032] This solution adds partitions and diversion channels to further optimize the drainage structure.
[0033] The partition separates the sump and the drain, preventing impurities from entering the drain from the sump and reducing the risk of drain pipe blockage.
[0034] The diversion trough can guide the rainwater in the sump to the bottom of the drain trough, allowing the rainwater to flow more smoothly into the drain pipe, avoiding direct impact of the rainwater on the drain pipe, reducing noise, and also retaining part of the rainwater as the water source for the backwash unit.
[0035] The U-shaped groove structure of the filter can increase the filtering area and improve the filtering efficiency, and the horizontal connecting plate can conveniently fix the filter on the water collection tank.
[0036] The notch and bolt connection allows for easy removal and cleaning of the filter.
[0037] The water pump delivers water to the nozzles to provide power for backwashing. The water pipe connects the water pump to the nozzles.
[0038] The nozzles are installed on the inner wall of the sump and the side wall of the partition, and can evenly spray high-pressure water to flush the entire filter surface and remove deposited impurities.
[0039] The evenly arranged nozzles can ensure that the entire filter surface is effectively flushed to remove all deposited impurities. The high-pressure water flow can effectively remove impurities and improve backwashing efficiency.
[0040] The fixing clamp can firmly fix the drain pipe to the side wall of the house to ensure that it will not loosen or fall off due to rain erosion or other reasons. It can improve the safety of the drain pipe and avoid accidental injury or property loss.
