Problems solved by technology

[0005] The present invention provides a BIM-based flip-chip construction method for large-scale steel structure rotating ramps, the purpose of which is to solve the problem that the rotating ramps used in large-scale venues proposed in the above background technology are generally relatively large, mostly relatively independent structural systems, and high in height. There are many components, most of which are arc-shaped, and the installation is difficult. This method has fast construction speed, high precision and obvious economic benefits.

Embodiment 1

[0043] Such as figure 1 The shown is a BIM-based flip-chip construction method for large-scale steel structure rotary ramps, which is suitable for the installation and construction of various complex steel structure rotary ramps. The "flip-chip method" is used to start installation from the top of the building and end at the bottom of the building , including the following steps:

[0044] 1. Construction preparation

[0045] (1) Establish a BIM model, determine the installation sequence of the rods, use software to establish a refined data model in the computer, and then use the method of reverse simulation to simulate the entire construction process, determine the installation sequence of the rods and number all the components;

[0046] (2) Assemble the upper and lower chords of the truss into a complete truss on the ground, and at the same time assemble the central pressure ring of the rotating ramp. After the two parts are assembled, they will be corrected, and the compone...

Abstract

The invention provides a BIM-based large steel structure rotating slope reverse construction method, which is applicable to spiral slope installation construction of various complicated steel structures. A reverse method is used; and the installation is started from the top of a building and is completed when the bottom of the building is reached. The method aims at solving the problems that rotary slopes used by large gymnasiums are generally large; most structures are relatively independent structure systems; the height is great; components are many; and most components are arc-shaped components, so that the installation difficulty is great. The method has the advantages that the construction speed is high; the precision is high; and the economic benefits are obvious.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a BIM-based flip-chip construction method for a large steel structure rotating ramp. Background technique [0002] With the development of the economy, more and more large-scale stadiums are being built, and with the continuous breakthrough of architectural design concepts, the structural forms of rotating ramps are gradually increasing. [0003] Among them, there is a circular concrete core tube in the middle, and the steel beam is connected to the concrete core tube through embedded parts, and the steel beam spirals up around the core tube to form a ramp. The structural form of the connection is also relatively common. [0004] However, since the rotating ramps used in large venues are generally large, most of them are relatively independent structural systems with high height and many components, and most of the components are arc-shaped, so the installation is difficu...
