Siphon drainage system for steel structure warehouse

Abstract

The invention relates to a siphon drainage system for a steel structure warehouse. The siphon drainage system comprises a plurality of siphon type roof drains embedded on a roof, a horizontal pipe, avertical pipe located under the horizontal pipe, and an outlet pipe located under the vertical pipe, each siphon type roof drain comprises a bucket body, a rectifier arranged inside the bucket body, and a fairwater arranged at the top portion of the bucket body; and the vertical pipe is arranged below a drainage hole, a connecting pipe is arranged between the vertical pipe and the horizontal pipe,the connecting pipe comprises an upper pipe part, a taper pipe part and a lower pipe part which are matched with the lower end of the vertical pipe, and multiple guide pipes are arranged between thebucket body and the taper pipe part. According to the siphon drainage system for the steel structure warehouse, the guide pipes and the connecting pipe are additionally arranged, the drainage efficiency is promoted by 1.21-1.37 times, the accumulated water depth of the roof can be reduced to the maximum extent, and the rain load on the roof is reduced to the minimum; and at the same time, rated flow of the siphon type roof drains is enhanced, the implementation effect is good, and the application value is high.

Description

technical field [0001] The invention relates to a siphon drainage system for a steel structure warehouse, belonging to the technical field of steel structure buildings. Background technique [0002] The principle of the siphon roof rainwater drainage system is to rely on the design of a special rain bucket to separate air and water, so that the rainwater standpipe is in a full flow state. When the water in the standpipe reaches a certain capacity, the siphon effect occurs. . During rainfall, the entire system drains rainwater from the roof surprisingly quickly thanks to the continuous siphon action. [0003] The existing siphonic roof rainwater drainage system usually consists of the following components: multiple siphonic rainwater buckets embedded in the roof, horizontal pipes, vertical pipes below the horizontal pipes, exit pipes below the vertical pipes, siphonic rainwater There are many bucket structures, for details, please refer to the "metal structure roof siphon r...

Problems solved by technology

[0005] Although the current siphonic roof rainwater drainage system has relatively high rainwater discharge, in the current siphonic rainwater bucket, due to the existence of the rectifier, although the rectifier can prevent the generation of eddy currents, it also limits the continuous increase of the rainwater flow in the vertical pipe, so that At present, the rainwater drainage efficiency of the siphonic roof rainwater drainage system has reached the bottleneck
