Reverse cumulative lifting construction method for single-layer spherical reticulated shell structure

Abstract

The invention belongs to the field of steel structure construction, and specifically relates to a single-layer spherical reticulated shell structure cumulative jacking construction method. The specific construction steps are as follows: Step 1: Determine the plane position for assembly, level the site, and position and set out the line; Step 2: According to the calculation Analyze the results, select several jacking points on the reticulated shell structure for the first jacking; Step 3: Set up the operating frame, and assemble the reticulated shell structure for the first jacking on the ground; Step 4: The first jacking operation, Lift the assembled reticulated shell structure to the height of one internode; Step 5: Install the rods of an internode under the assembled reticulated shell structure; Step 6: Cycle the fourth to fifth steps; Step 7: Install Structural support, remove the jacking bracket and jacking equipment. In the construction process of the invention, the force transmission is clear, the force conversion process is uniform and safe, the overall stability of the structure is good, the structure deformation is small, the construction precision is high, and the cost of temporary construction measures and the use of large mechanical equipment are reduced at the same time.

Description

technical field [0001] The invention belongs to the field of steel structure buildings, and in particular relates to a cumulative jacking construction method for a single-layer spherical reticulated shell structure. Background technique [0002] At present, the construction method of a single-layer spherical reticulated shell structure is generally hoisting in pieces or erecting a full-scale scaffolding assembly. The hoisting in pieces has high requirements for construction machinery, and a large number of support frames need to be erected. The amount of scaffolding assembled with full-scale scaffolding is very large, and the construction period is relatively short. Long, the installation quality cannot be guaranteed, and there are personnel safety issues. There are certain defects in the above two construction methods, and there are certain limitations in their application. In view of the above situation, a single-layer spherical reticulated shell structure reverse method ...
