Steel Structure Portal Rigid Framee
Dec 12, 2023
Portal rigid frame is a traditional structure system, the upper main frame of this kind of structure includes rigid frame inclined beam, rigid frame column, support, purlin, tie rod, gable frame and so on.
The portal rigid frame has the characteristics of simple force, clear force transmission path, fast component production, easy factory processing, short construction period, etc., so it is widely used in industrial and civil buildings such as industry, commerce, cultural and entertainment public facilities.
Portal frame light steel structure originated in the United States, has experienced nearly a hundred years of development, has become a relatively perfect design, production and construction standards of a structural system.
Portal rigid frame light steel structure is a branch of light steel structure, the main characteristics of this structure type are:
1.The light steel structure reflects the characteristics of light, fast and efficient, the application of energy-saving and environmentally friendly new building materials, to achieve factory processing and production, on-site construction and assembly, convenient and fast, saving construction cycle;
2.The structure is durable, the building appearance is novel and beautiful, the quality is good and the price is reasonable, and the economic benefits are obvious.
3.The size arrangement of column mesh is free and flexible, and can meet the construction and use requirements under different climatic conditions.
The main application scope of portal frame includes single-storey industrial workshops, civil supermarkets, exhibition halls and various types of warehouse industrial and civil buildings, etc., which has a wide range of market application prospects.
According to the type of structure, gantry rigid frame can be divided into single span, double span, multi-span rigid frame, rigid frame with eaves and rigid frame with roof.
The connection between the middle column and the inclined beam of the multi-span rigid frame is generally hinged. The multi-span rigid frame should be double-slope or single-slope roof. If necessary, the multi-span rigid frame composed of multiple double-slope roof can also be adopted. The beam column section can be equal section or variable section, and the column foot is generally hinged or rigid.
