Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] The BIM technology-based steel structure tension beam roof construction method disclosed in the present invention uses the BIM technology in the construction process of the spoke tension beam structure roof, and uses the BIM three-dimensional dynamic simulation of the entire construction process to estimate the completion time of the project.

[0041] A virtual spoke-type string beam structure roof was established through BIM in advance, such as figure 1 As shown, a total of 30 stringed box girders are arranged radially on the roof, and each stringed string 5 includes an upper stringer and a lower stringer. The upper stringer and the lower stringer are supported by vertical struts to form a stringer structure. The string beams 5 form a roof, and the roof st...

Abstract

The invention relates to a steel structure tension beam roof construction method based on a BIM technology, and belongs to the technical field of building construction. The BIM technology is applied in the construction process of a spoke-type string beam structure roof, a virtual spoke-type chord beam structure roof is established in advance through BIM, each lower chord beam is a pre-stressed cable, the cables are divided into three groups and two stages for circulation tension, the BIM technology is applied to perform simulation analysis of the whole process of the virtual cable tensioning construction, and the cable force and key point displacement of each lower chord beam in the tensioning process are dynamically tracked. According to the construction method, the BIM technology is applied to carry out three-dimensional dynamic simulation of the BIM in advance, and all the pre-stressed chord beams are subjected to three-batch two-stage cyclic tensioning; and on the premise of ensuring that the influence on the adjacent group of pre-stressed chord beams is minimal when the indifferent group of pre-stressed chord beams are inhaul cable tensioning construction, the construction period is reduced to the maximum extent. The required number of jacks is 1 / 3 that of the pre-stressed chord beams, and 2 / 3 of the original number of the jacks is decreased. The economic benefit is good,the construction quality control is good, mature operability is achieved, and the construction process safety is high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a steel structure tension beam roof based on BIM technology. Background technique [0002] Zhang Xianliang is a new type of hybrid roof system that is different from traditional structures. The string beam structure is a hybrid structural system formed by rigid components with upper chords, flexible cables, and vertical struts in the middle. One of the more successful creations in the development of hybrid structural systems. The tension string beam structure system is simple, the force is clear, the structural forms are diverse, and the advantages of rigid and flexible materials are fully utilized, and the manufacturing, transportation, and construction are simple and convenient, so it has a good application prospect. [0003] In the construction of the spoke-type tension beam structure roof, there are generally disadvantages of large in...
