Mechanical and electrical pipeline seismic applications in steel structure industrial workshop
In industrial workshops, there are common pipes installed for factory process production. Such as water supply and drainage, fire protection system, steam pipeline, hot water pipeline and gas pipeline system, etc. The mechanical and electrical pipelines of steel structure industrial workshops are intricate.
The installation design and construction of the anti-seismic support of the steel structure industrial workshops are complicated, and there are many difficulties in rooting the steel structure. Through the design calculation of the anti-seismic support and the structural characteristics of the site, the anti-seismic support of the inter-professional electromechanical pipeline and the anti-seismic support of the single-system electromechanical pipeline are designed. The rooting of the steel structure adopts beams Clamp fixed channel steel for rooting.
In steel structure industrial workshops, according to the design of anti-seismic supports in different types of electromechanical pipelines, if there are rigidly connected pipes for water supply, hot water and fire protection pipes, the maximum distance between anti-seismic supports and hangers is 12.0m laterally and 24.0m longitudinally. When flexibly connecting metal pipes, non-metallic pipes and composite pipes, the maximum distance between seismic supports and hangers is 6.0m laterally and 12.0m vertically.
Multi-storey buildings in areas with degrees 8 and below can be selected according to the materials specified in the current standards. The main pipes and standpipes of high-rise buildings and buildings in 9-degree areas should adopt copper pipes, stainless steel pipes, metal composite pipes and other high-strength and ductile pipes, and the connection methods can be connected by pipe fittings or welding. When the cable tray is made of rigid material, the maximum distance between the seismic supports and hangers is 12.0m laterally and 24.0m vertically.
For rigidly connected horizontal pipes, the longitudinal offset value is allowed between two adjacent seismic supports and hangers. Wire bushings shall not exceed 1/16 of the maximum side support hanger spacing and cable ladders, cable trays and cable troughs shall not exceed twice their width.
Tray-type, trough-type, step-type, glass anti-corrosion and flame-retardant cable trays or ordinary steel bridges can be selected according to the site environment and technical requirements. It is advisable to add a cover plate in the environment or outdoor places that are easy to accumulate dust and need to be covered.
In the construction industry, with the use of steel structure workshops becoming more and more popular, the manufacturing, transportation and installation technology of steel structure workshops has received more and more attention, and has also achieved rapid development and continuous improvement. Following the pace of the times, we are committed to the steel structure energy-saving construction industry, and are willing to cooperate with all sectors of society to create a green, environmentally friendly and beautiful future.
