Kahulugan ng Large-Span Spatial Steel Structure
Ang large-span spatial steel structure ay isang steel structure system na may span na mahigit 30m at pangunahing gumagamit ng spatial grid o prestressed structure. Malawak itong ginagamit sa mga stadium, airport terminal, malalaking logistics warehouse, at iba pang gusali.
Mahahalagang Punto sa Lifting
Sa pag-angat ng large-span steel structure, kailangang isaalang-alang ang bigat ng component, lokasyon ng lifting points, at construction conditions. Ang Phase I ng Shenzhen Pinghu South Comprehensive Logistics Hub ay may lawak na 500,000㎡ at 35,000 toneladang steel structure, kaya napakataas ng requirement sa pagpili ng lifting equipment at construction organization.
Design ng Temporary Support System
Dapat isaalang-alang sa design ng temporary support system ang self-weight ng structure, construction load, wind load, at iba pang salik. Sa paggamit ng staged unloading technology, epektibong makokontrol ang final geometry at deformation ng structure.
