Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a siphon drain outlet filtering device for a metal roof. Background Art

[0002] With the increasing use of metal roofs in modern buildings, the waterproof performance of metal roofs is increasingly closely related to people's production and life. The waterproof performance of metal roofs mainly depends on the anti-leakage performance and timely drainage. Often, the design, production, and construction units are most concerned about the anti-leakage performance of metal roofs, but in fact, whether the metal roof can be drained in time is equally important.

[0003] If the metal roof cannot be drained in time, rainwater will first accumulate and cause leakage in the metal roof; secondly, excessive accumulation of rainwater will increase the load on the metal roof and affect the safety of the roof structure.

[0004] At present, the most common drainage method for metal roofs is: the drainage ditch collects the flowing rainwater; the water collection well collects the rainwater; and then the rainwater is discharged into the urban pipe network through the siphon drainage outlet at the bottom of the water collection well and connected to the rainwater pipe. In the actual engineering application process, it is found that garbage (such as leaves, branches, dust, and other floating objects) is easily accumulated on the roof. The garbage is washed by rainwater, flows through the drainage ditch, and collects in the water collection well. It is very easy to cause the siphon drainage device to be blocked, affecting the drainage effect. In severe cases, it directly causes the complete failure of the siphon drainage, causing a large amount of rainwater to be retained on the metal roof, which in turn causes water overflow and causes serious leakage on the roof. Even due to the continuous increase in rainwater load, the structure of the metal roof is damaged, which directly causes safety accidents.

[0005] The existing solution to this problem is to arrange special personnel to regularly clean the roof drains, water collection wells and siphon drain holes, which consumes manpower and material resources. Whenever it rains, special personnel need to be arranged to check the roof drains, water collection wells and siphon drain outlets to ensure smooth drainage. Since metal roofs are slippery on rainy days and are high-altitude operations, there are major safety hazards in clearing operations on rainy days. Utility Model Content
