套管式爬升脚手架试验研究

A Research of Loading Test Into Problems on the Tubular Lifting Scaffold

通过对爬架片作足尺模型加载试验，从理论上分析了爬架的受力特点，对试件各杆件、焊接节点、外立杆进行了研究；从爬架极限承载力，试件变形、加力点沉降量、杆件内应力等几方面测试、观察、分析，得出的结论。为套管式脚手架的推广应用及安全保证提供了理论依据。

Through a full scale model loading test of the tubular lifting scaffold, ithas demonstrated clearly the ultimate bearing capacities of its members and done on asound theoretical basis. All members of the tubular lifting scaffold, including items such as:its welding joints. its specimens' deformations, its key points' deflections and its members'internal stresses etc. have been tested. recorded. investigated and analyzed. In conclusion. ithas confirmed that tubular lifting scaffold is superior in construction and there forshould be popularized in the future.
