Description
Technical Field
The utility model belongs to the metal containment system field of large-span steel construction building specifically, relates to a location locking bearing structure of metal roofing.
Background
The steel structure building is gradually becoming a substitute of a concrete structure due to the advantages of light weight, high strength, rapid construction, green and energy conservation, large-span shaping and the like, has become a mainstream of application in some special fields, and also puts higher requirements on a roof system matched with the steel structure building. The metal roof is widely popularized and applied in China as an important roof system.
The metal roof can not only realize the normal function of resisting wind and rain, but also enable the building to generate stronger modern sense and times breath, and also accord with the principle of green environmental protection sustainable development, so the metal roof is widely applied to roofs of large modern public buildings such as airport terminal buildings, large-scale exhibition rooms, gymnasiums, novel railway stations and the like.
Among them, the metal roof standing-seam crimping system is most widely applied at the present stage. The roof board of the system is fixed by clamping the roof board on the plum blossom head of the fixed seat and then locking the board ribs on the fixed seat by using an electric serging machine.

However, in this connection, the roof panel ribs are not directly and effectively fixed to the plum blossom-shaped heads of the fixing seats, so that a slidable metal roof system is formed. This causes the following problems:
1. as the temperature changes, the metal roofing system can bear greater temperature stresses. Under the repeated stress action of expansion with heat and contraction with cold, the system can produce repeated telescopic deformation and asynchronous slippage. This is because slidable metal roofing system, does not have direct effectual fixed between the plum blossom head of roof boarding rib and fixing base, and when the system produced the deformation of stretching out and drawing back repeatedly, both can not the one-to-one, produced dislocation and deviated each other. The original occlusion position is deviated, and the positioning can not be realized. Thereby causing the disadvantages of the original occlusion mode and reducing the bearing capacity and the wind uncovering resistance of the structure.
2. When wind load acts on the roof, the bending and shearing resistance bearing forces between the plates of the metal roofing system and between the plates and the supports are transmitted by repeated rubbing for a long time. In the existing slidable metal roof system, the plates and the support are not directly and effectively fixed, so that the abrasion of the plum blossom heads of the roof plate and the fixing seat at the position of the fixing seat is thinned and reduced, even the fixing seat falls off, and the whole system cannot be locked, so that the wind resistance of the whole roof is reduced, and the whole roof is lifted and damaged under severe weather conditions.
