Problems solved by technology

The traditional method is that in the installation and construction of the ball joint in the rotating device, most of the construction personnel complete it under the condition of two-dimensional drawings. Since they do not have an intuitive understanding of the physical structure of the ball joint and have no vivid understanding of the installation process, it is easy to Deviations will affect the installation quality and construction progress

Embodiment 1

[0040] In an embodiment of the present invention, a BIM-based method for simulating construction of a rotating device for a pier-top swivel bridge includes the following steps:

[0041] 1) Creation of BIM model component family files: according to the construction drawings, use Revit software to establish family files of related components of bridge pier, rotating device, and beam body 0# section;

[0042] The family file contains the technical parameter information of the component. By establishing the reference surface or reference line and using the alignment command to associate the technical parameters of the 3D model, the model can be informatized and parameterized. During the simulated installation and construction process, the installation scheme can be optimized and adjusted by adjusting the component type parameters.

[0043] The establishment of the family type file of the BIM model component also includes the following steps:

[0044] 1-1), determine the family ca...

Embodiment 2

[0063] A BIM-based construction simulation method for a rotating device of a pier-top swivel bridge. The embodiment of the present invention is further limited on the basis of embodiment 1.

[0064] Further, preferably, the family file includes the steel bar family category, the pier pier family category, the bridge pier pallet family category, the girder body 0# segment family category, and the rotating device series family category; the rotating device series family category includes spherical hinges Brackets, slideway brackets, lower ball joints, sliders, upper ball joints, steel casings, connecting plates, pins and bolts.

Abstract

The invention relates to a construction simulation method, in particular to a BIM-based pier top swivel bridge rotating device construction simulation method, which comprises the following steps of: establishing a group type file of a BIM model component, and establishing a group file of a pier, a rotating device and a beam body 0 # segment by utilizing Revit software; Establishing a project fileof the BIM model component, establishing a three-dimensional model, and establishing a project file with the pier top swivel device installation model as the name by using Revit software; Manufacturing and installing a three-dimensional simulation animation, and establishing a bridge pier, a rotating device and a beam body 0 # segment step-by-step simulation construction animation file by utilizing Navisworks software; And carrying out construction scheme making and technical disclosure training. According to the method, the abstract and complex installation and construction process of the bridge pier top swivel rotating device can be simulated in a three-dimensional model animation mode for scheme research and technical communication, constructors can visually know construction objects, steps and requirements, and therefore the construction accuracy and precision are improved, rework caused by errors is avoided, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a construction simulation method, in particular to a BIM-based construction simulation method for a rotating device of a pier top swivel bridge. Background technique [0002] In bridge projects spanning existing railways and highways, the use of the swivel method can reduce the impact on the operation of existing lines. The pier top swivel method is one of the common methods of bridge swivel construction. There are many construction techniques and high precision requirements for the swivel of the bridge pier top, especially the installation of the spherical joint in the swivel device is the key to the smooth progress of the swivel. The traditional method is that in the installation and construction of the ball joint in the rotating device, most of the construction personnel complete it under the condition of two-dimensional drawings. Since they do not have an intuitive understanding of the physical structure of the ball joint ...
