The Support Type And Function Of Steel Structure Workshop
In the application of steel structure, the application of steel structure workshop is undoubtedly the most, other steel structure applications such as the application of steel structure color steel plate activity room and the application of steel structure canopy, these are steel structure buildings with high building requirements, and they have been well tested in the construction market.
The support types of steel structure workshop buildings are divided into roof support and intercolumn support.
The role of roof support:
(1) Ensure the overall role of the structure in space
The roof structure, consisting of planar frames and roofing materials, is an unstable system, and all the roof trusses supported on the top of the columns may fall towards one case. If some roof trusses are connected with supports in appropriate parts to become a stable space system, and the rest of the roof trusses are connected to this space stability system by other components, the stability of the entire roof structure is ensured and it becomes a spatial whole.
(2) Avoid lateral instability of the pressure rod and prevent excessive vibration of the tie rod
The support can be used as the lateral support point of the roof truss chord, reduce the calculated length of the chord outside the roof truss plane, ensure the lateral stability of the compression chord, and make the pulled down chord not produce excessive vibration under certain dynamic actions (such as when the crane is running).
(3) Bear and transfer horizontal loads
(4) Ensure the stability and convenience of structural installation
The installation of the roof generally starts from one end of the temperature section of the house, and first uses supports to connect the two adjacent roof trusses to form a basic spatial stabilizer, on the basis of which other components can be installed sequentially.
The role of inter-column support:
(1) Form a strong longitudinal structure to ensure the longitudinal rigidity of the plant.
(2) Bear the wind load of the gable at the end of the plant, the longitudinal horizontal load of the crane and the temperature stress in the seismic area, etc. should still bear the seismic force of the longitudinal plant and transmit it to the foundation.
(3) It can be used as the fulcrum of the frame column outside the frame plane to reduce the calculated length of the column outside the frame plane.
