Net frame integral installation device and construction method thereof

Abstract

The invention discloses a net frame integral installation device and a construction method thereof. The net frame integral installation device comprises a self-balancing lifting device, a temporary supporting seat and a temporary supporting frame for additionally adding rods in high altitude in a net frame joint. The construction method comprises the steps that (1) an original structure supportingseat of the net frame is installed; (2) the temporary supporting seat for additionally adding the rods in high altitude in the net frame joint is manufactured; (3) a net frame structure is assembled;(4) a temporary balance supporting seat and a main balance supporting seat are installed; (5) a hydraulic cylinder for lifting is installed; (6) the net frame is lifted; (7) the rods are additionallyadded in high altitude in the net frame; (8) the temporary supporting seat for additionally adding the rods in high altitude in the net frame joint is dissembled; (9) a self-balancing adjusting shoulder pole beam is dissembled; (10) the temporary balance supporting seat and the main balance supporting seat are disassembled; and (11) the temporary supporting frame is dissembled. According to the net frame integral installation device and the construction method thereof, self balancing is achieved between symmetrical force points on the temporary supporting frame in the lifting process, the center of a lifting device and the center of the temporary supporting frame are in the same lead line to ensure that the axis of the temporary supporting frame is stressed, the rods are accurately addedon the net frame, and the safety of lifting of the net frame and the accuracy of the construction are improved.

Description

technical field [0001] The invention belongs to the technical field of on-site assembly and construction of a grid structure system, and in particular relates to a grid overall installation device and a construction method thereof. Background technique [0002] At present, the grid structure system is developing rapidly. Because of its light weight, high rigidity, and good seismic performance, it is widely used in gymnasiums, theaters, exhibition halls, stadiums, airports and other construction facilities. This type of structure usually has a large overall span, which can meet the structural system requirements of various large-span public buildings. The common construction method of the current grid structure is: setting hydraulic cylinders and other lifting equipment at multiple points above the grid structure, and synchronously lifting through computer control to realize the overall hoisting of the grid structure. There are several problems in this construction method: (...

AI Technical Summary

Problems solved by technology

There are several problems in this construction method: (1) Temporary support frames need to be set up for the overall lifting of the grid structure, and multiple lifting force points should be set on the temporary support frames. If there are no reliable measures, the resultant force of multiple lifting force points and temporary The axis of the support frame is inconsistent, causing the temporary support frame to be eccentrically stressed, which further increases the difficulty of controlling the overall stability of the temporary support frame, and may even cause safety hazards that are difficult to control due to instability during the dynamic installation process; (2) Overall During the lifting process, the poles that coincide with the horizontal projection surface of the temporary support frame need to wait for the overall structure to be lifted into place before the high-altitude pole repair can be performed. The cost of safety measures for high-altitude pole repairs is increased, it is uneconomical, and the role of temporary support frames is not fully utilized
