Factory rental talk about the cause of water leakage in the factory.

1. Reasons for design scheme.

1. The roof drainage system software does not set overflow countermeasures according to the standard. When the compressive strength of rainstorm exceeds the sewage discharge capacity of the precipitation system software, it will exceed the overlapping joints and even the flat roof, leading to network security accidents.

2. The total number of drainage pipes is insufficient, and the mobility distance and time of precipitation along the gutter are long, resulting in backwater; The upper end of the wall is not provided with L-shaped side, which leads to water seepage inside the drainage ditch.

The design scheme of Caigang roof drainage fittings is unscientific and cannot achieve the actual effect of waterproofing.

4. The standard requires the deformation operation value of prefabricated building components, and the steel purlin cross-section design scheme is small. If the interval is too large, the deformation of steel purlins and profiled steel sheets under wind load will be too large.

Without considering structural deformation, temperature difference deformation, drying shrinkage deformation, vibration and other hazards, the deployment does not meet the needs of rural base deformation.

6 in the specific design scheme, the roof slope of many steel structure warehouse two-story building projects is too small, and the precipitation on the flat roof cannot be discharged into the ditch immediately.

7. The canopy is designed with backwater conditions, resulting in water seepage at the canopy position.

3. Application and maintenance.

The load on the steel purlin rises at will, resulting in roof deformation.

The precipitation castor accumulates a lot of pollution and has water retaining function.

3. Waterproof glue. The sealant is brittle and lacks necessary maintenance during the whole application process.
