As we all know, poor corrosion is a fatal shortcoming of bolt ball space frame, so in the design of steel structure, we must pay attention to its drainage effect, and must not cause water dredging. How to do a good job of waterproof engineering is directly related to the service cycle of the steel structure of the space frame, so it is very important to do a good job of roof waterproof.
Now in many buildings will be widely used steel structure space frame, because the steel space frame structure compared with the traditional concrete building has its particularity, because in the steel design and construction of the building will use different building materials for building patchwork and overlap, so that the waterproof technology of steel structure building is mainly based on dredge-oriented, blocking as a supplement.
At present, the use effect of waterproof materials for steel structure houses is not very ideal and the life is short, so building selection, drainage organization, structural design has become the top priority of waterproof design for steel structure buildings. In practical engineering, the waterproof performance of steel structure buildings can be guaranteed or improved from the following points:
1, building selection, as far as possible to choose a single ridge form, to avoid the appearance of ditches in the building, the same side ditches are also as far as possible to use the outer gutter and avoid the inner gutter; The roof plate type should be reasonably selected according to the drainage slope and slope length, the slope is small and the slope is long, then the roof plate should use the wave high plate type.
Water leakage in steel structure buildings is often not a design problem, and is often caused by the construction unit in the construction process, so the strict control of the construction quality of the space frame company is also an important aspect of the waterproof steel structure.
2, structural measures, first of all, we must be familiar with the various methods of steel structure waterproof structural measures, flexible use in the actual project, waterproof materials must be used in the place.
3, drainage organization, reasonable layout of drainage points, it should be noted that the precipitation intensity of each region is different, drainage organization design is to have sufficient theoretical basis, rather than subjective feeling.
