RESEARCH ON CONSTRUCTION TECHNOLOGY OF LARGE-SPAN SPLIT-LEVEL MULTI-CURVED WELDED SPHERICAL STEEL MESH FRAME
The general construction process of large-span split-level multi-curved welded spherical steel grid includes:first,according to the existing construction drawings to locate the payout,determine the control point of the ball.Then build the support frame body,carry out the welding ball and the installation of the grid bar;After checking that the steel grid meets the design form,the lifting point of the steel grid is set according to the construction simulation results.The weld is inspected before lifting,and the displacement and deflection monitoring is carried out during the construction process to ensure the overall safety of the steel grid.The monitoring results show that the actual construction of the grid conforms to the requirements of the design scheme,which indicates that the construction technology adopted can meet the construction requirements of large-span split-layer multi-curved welded spherical steel grid.
