Description

Technical Field

[0001] The utility model relates to a large-span flexible support roof. Background Art

[0002] A roof refers to the top structure of a building. A roof is usually composed of load-bearing members and covering members. The load-bearing members include purlins, ridges, crossbeams, etc., and the covering layer includes tiles, metal plates, etc. The main function of the roof is to protect the entire house from wind and rain, and at the same time play the roles of heat preservation, cold insulation and sunshade. The roof is mostly arranged on the roof slab. In the construction industry, steel structures provide many opportunities for steel structure projects due to their easy construction and excellent performance. Steel structure grids have become the main structural forms of existing roof trusses and have played a huge role in reflecting the architectural shape and realizing the use function. Common roof structure forms include thin-shell structures, space grid structures, three-dimensional truss structures, etc. At present, steel pipe truss structures in China are receiving more and more attention and are widely used. It is formed by welding steel pipes together organically. The space pipe truss structure is developed on the basis of the reticulated shell structure and the grid structure, usually with a triangular cross-section and good stability.

[0003] In the existing roof, most of the load-bearing members are connected to the wall, and the middle is an overhead structure, making the load-bearing capacity of this roof poor and unable to achieve a large span, thus limiting its application range; and most of the existing roof trusses are rigidly connected to the roof or the wall, and rigid failures occur under vibration or load. For example, CN116556506A discloses an assembled cold-formed thin-walled steel structure house system, including a roof, a floor, a combined wall, a staircase, a connecting piece, a base, a double-insulation structure and a double-interlayer structure; the floor is embedded inside the combined wall, and the roof is arranged on the top of the combined wall, and the roof, the floor, the combined wall, the staircase and the base and inside the roof, the floor, the combined wall and the staircase are all fixedly connected through different connecting pieces, and the bottom of the combined wall is located on the base. This roof includes multiple groups of roof trusses and multiple groups of combined plates; the roof trusses are upwardly convex triangular structures, and multiple groups of roof trusses are connected to each other through ceiling keels; the combined plates are arranged between adjacent two groups of roof trusses (12) through anti-lifting connecting hardware, and the combined plates are laid in a staggered manner with each other. The roof trusses in CN116556506A are tripods. Although they have sufficient rigidity, they do not have energy absorption ability, so they are poor in withstanding wind, snow and other loads, and the covering plates of the floor and the roof trusses are often separated under relatively harsh climates, so the safety is poor.
