Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure construction, and particularly relates to an assembled unloading structure applicable to steel structure space lattice shells and grid structures. Background Art

[0002] Steel structure space lattice shells or grid structures are widely used in modern large-span roof main structures due to their good visual effects of space structures. During their implementation, many construction methods such as the jacking method and the high-altitude scattered assembly method for each unit are often used. First, the entire roof structure needs to be jacked up to the design elevation or assembled and then unloaded, so as to convert the structural force system, and transfer the self-weight of the roof structure from the temporary support frame to the permanent support. The implementation of this conversion process usually shows the conversion of the elevation of the roof structure, that is, the elevation of the temporary support frame is usually higher than that of the permanent support.

[0003] Electronic control hydraulic synchronous unloading is the unloading method with the highest unloading synchronization rate and accuracy in the existing unloading technologies. The main hydraulic jacks for unloading are usually installed on the top of the temporary support.

[0004] When the existing steel structure space lattice shells or grid structures are converting the structural force system during construction, due to many factors such as the specifications and dimensions of the temporary support frame, construction operation conditions, cost control, and safety control, it is often impossible to use the electronic control hydraulic synchronous unloading method for system conversion. This leads to complex operations, high implementation costs, and high requirements for on-site construction operation conditions and the structural form of the temporary support frame during the conversion of the structural force system.
