Description

Technical Field

[0001] The present application relates to the technical field of drainage, and in particular to a rainwater downpipe for a building. Background Art

[0002] At present, most buildings have ordinary PVC downpipes installed on the exterior walls. In the north, rainwater has a long interval throughout the year, which results in residual scale inside the downpipes after rain. In addition, there will be a lot of dust and impurities falling inside the downpipes due to no rain for a period of time, causing blockage. In the south, there is more rain, and because the rainy season lasts for a long time, the bottom of the downpipe will be under water pressure for a long time when draining water, which will cause damage to the bottom of the downpipe.

[0003] Announcement No. CN217601892U proposes a new type of building rainwater downpipe, which is arranged on the facade of the building wall along the wall, including a dust net, a slot, a downpipe body, a thread, a downspout, a buffer pipe, and a descaling agent. A dust net is provided at the top of the downspout, and slots are provided on both sides. The descaling agent is placed in the slots. The downpipe body has threads at both ends, and the thread diameter of the upper end of each section of the downpipe body is 1 cm larger than the thread diameter of the lower end. A buffer pipe is provided at one-third of the bottom of the downpipe body, and the downpipe bodies are screwed together by threads to form an integrated structure. The utility model adopts a threaded splicing method and a design method of adding a dust net and a descaling agent at the downspout, which increases the integrity of the building rainwater downpipe, facilitates the replacement of a single downpipe body after damage, reduces the damage of scale to the pipe body itself, improves the use efficiency of the downpipe, increases the service life of the downpipe, and avoids the waste of the downpipe.

[0004] In the actual use of the above case, the impact force inside the water pipe is reduced by designing a prismatic pipe. This not only requires additional mold design, but also requires multiple replacements of the prismatic pipe, which increases the cost and replacement frequency. For this reason, we propose a rainwater downpipe for buildings. Utility Model Content
