Problems solved by technology
In addition, due to the initial defects of the scaffold structure and components, such as the initial bending and corrosion of the rods, the size error of the erection, and the eccentricity of the load, the rationality of the force of the scaffold structure is poor. There are architectural defects and structural defects in the exhibition hall

The invention relates to a multi-stage assembly type lattice framework building structure which comprises a main structure and a sub structure arranged on the main structure. The main structure is of a lattice portal framework structure which comprises a plurality of vertical truss assemblies arranged in parallel and horizontal truss assemblies arranged between every two adjacent vertical truss assemblies. Every two adjacent vertical truss assemblies are connected together through the horizontal truss assemblies. The sub structure is of a detachable scaffold structure and is used for transmitting gravity loads to the main structure. Compared with the prior art, the scaffold structure, the portal framework structure and the lattice structure are combined together, the assembly type building structure is formed through a reasonable connection mode, the whole structure is clear and reasonable in stress, the requirement of a vertical bearing system and the requirement for lateral rigidity under wind loads can both be met through mutual cooperation of the main structure and the sub structure, and the multi-stage assembly type lattice framework building structure is convenient to detach and can meet the requirement of temporary buildings.
Description
technical field [0001] The invention belongs to the technical field of building structure engineering and relates to a multi-stage assembled lattice frame building structure. Background technique [0002] In recent years, with the development of my country's construction industry, building structures have gradually shown a trend of diversification. Portal rigid frame is a common building structure, mainly including rigid frame inclined beams, rigid frame columns, supports, purlins, tie rods, gable skeletons, etc. Houses with portal frame structure have the characteristics of simple force bearing, clear force transmission path, quick component manufacturing, convenient factory processing, and short construction period, so they are mostly used in industrial and civil buildings such as industrial, commercial, cultural and entertainment public facilities. The portal frame structure is specifically used in single-storey factory buildings, civil construction supermarkets and exhi...
