Problems solved by technology

One is that it is difficult to select the assembly posture. The arrangement of the rods of this type of structure is very irregular and the number of layers is large. If the original posture is used for assembly, the layout of the assembly tire frame is difficult, and due to the high height of the roof structure, the mass distribution is uneven , the stability of the roof structure and the assembled tire frame is difficult to be effectively guaranteed; second, the height of the irregular space structure from the ground is usually very large. There is a greater risk to the security of

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0038] ginseng figure 1 As shown, the embodiment of the present invention provides a construction method for high-altitude turnover and lifting of an irregular space grid structure.

[0039] The irregular spatial grid structure 8 has the characteristics of large overhangs, messy arrangement of rods, and large uneven mass distribution. ginseng figure 1 As shown in the figure, a BIM-based space grid structure turning over construction method includes a main mechanical lifting device 1 and an auxiliary mechanical lifting device 2, and the lifting ropes 5 and 6 of the lifting device 1 are connected with the irregular space respectively. The lifting points 9 and 10 on the grid structure 3 are connected; the lifting rope 7 of the lifting device 2 is connected to the lifting point 11 on the irregular space grid structure 3; the hook 12 of the lifti...

Abstract

The invention relates to a space grid structure turn-over and base stripping construction method based on a BIM technology. The construction method includes the main steps that a main machine hoistingdevice is slowly lifted in the vertical direction, an irregular space grid structure gradually rotates around a hoisting hook of an auxiliary machine hoisting device to be in an in-place posture; based on BIM, coordinates (Xi, Yi, Zi) of the hoisting hook and coordinates (Xj, Yj, Zj) of a hoisting point are dynamically monitored in the rotating process, the distance Lk between the two ends of each hoisting rope is obtained due to conversion, the actual lengths L0 of the hoisting ropes are compared in real time, and a stress state (Lk<L0: a loose state, Lk=L0: a critical state, Lk>L0: a tightened state) of the hoisting ropes are judged. According to the method, in combination with strong construction simulation analysis and a colliding check function of the BIM technology, it is achieved that the irregular space grid structure gradually completes turn-over and base stripping construction in a manner that main and auxiliary hoisting machines are combined from a reasonable splicing posture low in gravity center.

Description

technical field [0001] The invention relates to a BIM technology-based construction method for a spatial grid structure turning over and being reborn, and belongs to the technical field of building steel structure construction. Background technique [0002] With the rapid development of my country's economy and construction technology, people's requirements for architectural aesthetics have been continuously improved, and a large number of space structures with unique shapes and complex stresses have gradually emerged. [0003] With the development and maturity of steel structure design and construction technology, there are many large-span and irregular space grid structure projects in China. Some steel structure roofs of station buildings and exhibitions adopt irregular space grid structure, and their shapes are novel. It is beautiful and very artistic, but it undoubtedly increases the difficulty of steel structure installation. One is that it is difficult to select the a...
