How to choose the space frame support in space frame processing?


How to choose the space frame support in the space frame processing? The space frame is warmly welcomed by the construction market for its high-efficiency bearing characteristics, novel and beautiful style, and fast and convenient engineering construction. The space frame is mainly used in large and medium-span buildings, such as high-speed railways, stadium steel structure, steel structure workshop, glass dome building, high-speed toll stations, coal sheds, etc. The larger the span, the more obvious the advantages and economic development effects of using space frames.
When designing the support connection points of the space frame, it should be based on the type of the space frame, the size of the span, the functional load status, the cross-sectional shape of the space frame members, and its production, processing, manufacturing methods, and engineering construction installation methods. Way support.
In terms of internal structure, the seismic-grade steel space frame support not only has a large bearing capacity but also has a relatively high level of deformation capacity. The plastic material of the coal shed space frame support is a high-elastic material. Although it can give the product the ability to deform, if the anti-seismic steel support is only made of plastic, it can only meet the elastic calibration requirements of the building. It does not meet the rigidity requirements of the building.
In terms of appearance design and structure, the space frame support is based on the installation characteristics of the anti-seismic grade steel support on the building. Its geometric shape can be designed as a cylinder, and can also be designed as a rectangle or cube.
Among them, the effective structural specifications of the space frame support can not only meet the load-bearing capacity bending stiffness and horizontal deformation requirements of the seismic-grade steel support but also enable it to support the building and bear the abnormal deformation of the building under negative pressure.
When choosing a space frame support, pay attention to the size of the bearing capacity, the size of the longitudinal tension, the size of the horizontal force, and pay attention to the offset and corner. Unilateral active type, fixed type. The orientation of the tube bundle of the shock-absorbing support is given deflection and bending stiffness, which is necessary for the better shock-absorbing of the space frame project.
