Description

Technical Field

[0002] The steel roof truss is an important part of the steel structure workshop, bearing the load of the entire roof and maintaining the stability of the frame structure of the steel structure workshop. Commonly used steel roof trusses are divided into structural forms such as welded structures, truss structures, and screw rod structures, and both ends of the roof truss are fixed on the top of the steel columns; due to the large span of the steel roof truss, the steel roof truss often has local torsional bending, resulting in the spacing between adjacent two steel roof trusses not meeting the design requirements, and the verticality at the mid-span and the lateral bending deflection exceeding the standard, affecting the stress of the steel roof truss, further affecting the structural life, and even resulting in serious consequences such as buckling instability and roof collapse, and there may also be a situation where the diagonal bracing of the roof truss cannot be installed smoothly. At the same time, the height of the steel roof truss from the ground is usually more than 10m, and in some cases, it can reach 30m. Therefore, when the steel roof truss has torsional bending and the spacing between adjacent two steel roof trusses does not meet the design requirements, how to adjust this spacing in a timely and effective manner during high-altitude operations to meet the design and installation requirements is a technical difficulty encountered at present.
