Space frame has the advantages of easy installation, regular shape, light weight, high stiffness, good seismic performance, etc. Space frame upper or lower chord members can be arranged in a regular way into a square, rectangular, triangular and other mesh, the upper and lower chord members are connected through the diagonal web to form a spatial stress system.
With the development of society,people's demand for infrastructure is increasing day by day, and the infrastructure construction of some cement, electric power, coal and other industries has undergone tremendous development.
Existing space frame structure due to changes in load, some local rods will be in the stability test stress exceeds the allowable stress, some small tension ties into compression rods and bending deformation.
For the reinforcement of three-dimensional truss, the additional tension chord reinforcement can be adopted. The upper and lower chords of three-dimensional truss are generally continuous rods with less variation of pipe diameter and wall thickness, which can withstand larger axial force, and it is convenient to install nodal plates on the fittings with clamps, which is more suitable for adding tension chords to form a three-dimensional truss structure.
This coal shed closed reconstruction project researches the overall jacking technology in the construction of the arched space frame . There are structures that are fully utilized and lifted in stages , so that the arched space frame can be lifted and assembled at the same time , effectively improving the efficiency and quality of the arched space frame construction.
