Description

Technical Field

[0001] The utility model relates to the technical field of diversion buffering, in particular to a rainwater diversion structure for high-low cross roofs. Background Technique

[0002] In the related art, in order to increase the ventilation and air change inside the factory building, the roof is usually partially raised in the middle of the factory building.

[0003] When designing the drainage of the high-span roof of the existing high-low cross roof, it can be divided into two types: using rainwater pipes to hang inside the factory building, hanging to the outer wall of the factory building, buried underground or extending outdoors at the ground level. This method has a high cost, occupies the internal height of the factory building, and increases the load of the structural beam.

This method saves indoor space and reduces the hanging load of the structure. However, the rainwater coming down from the high span is relatively fast. After long-term use, it will cause problems such as damage to the coiled material, damage to the surface coating of the profiled sheet, and displacement of the profiled sheet or coiled material on the low-span roof under the long-term high-speed rain erosion.
