How to Choose the Space Frame Support

2021-04-30

The space frame is welcomed by the construction market because of its high efficiency, novelty, beautiful appearance, quick construction and convenience. The space frame is mainly used in large and medium-sized buildings such as high-speed railway stations, gymnasiums, industrial workshops, charging stations, and coal sheds. The larger the span, the more obvious the superiority and economic benefits of the space frame. So how to choose the space frame support in the application?

 

When designing space truss support nodes, appropriate supports should be selected according to the frame type, span size, acting load, cross-sectional shape of the truss components, processing and manufacturing methods, and construction and installation methods. In the internal structure, the seismic steel truss should not only have a large bearing capacity, but also a high horizontal deformation capacity.

 

The rubber material supported by the coal shed is a highly elastic material. Although it can give the product deformability, the seismic steel support can only be made of rubber material, which can only meet the elastic reset of the building, but cannot meet the rigidity requirements of the building. In terms of shape and structure, the support can be designed as a cylinder, or a cuboid or a cuboid, according to the installation characteristics of the seismic steel support for the building. Reasonable truss structure size can not only meet the requirements of bearing capacity rigidity and horizontal deformation of seismic steel bearings, but also enable the truss to support the building under static pressure and withstand abnormal deformation.

 

When selecting the support, pay attention to the bearing capacity, vertical tension and horizontal force, and pay attention to the displacement and rotation angle. The restraint directions of the damping support, namely displacement and stiffness, are given, which are the needs of engineering shock absorption.
