Embodiment Construction

[0012] In order to make the technical means, creative features, goals and functions achieved by the present invention clearer and easier to understand, the present invention will be further elaborated below in conjunction with specific embodiments:

[0013] The present invention proposes a steel structure box girder simulation method, including the following steps 1), erecting steel box formwork, including skeleton modeling, box girder shell modeling and box girder diaphragm modeling, and positioning the skeleton for parameterized change The steel box girder hooks the model as a whole. The axis of the steel box girder is created by the expression of the number of lines or the fitting method of the horizontal and vertical lines. The shell of the box girder includes the top plate, bottom plate and side plate. The surface of the knife is used to cut the initial mold of the diaphragm; 2), the software is used for secondary development to realize the rapid generation of the model, a...

Abstract

The invention provides a steel structure box girder simulation method. The method comprises the following steps of 1, erecting a steel box die, wherein framework modeling, box beam shell modeling andbox beam transverse clapboard modeling are involved; 2, utilizing software for secondary development to quickly generate a model; 3, utilizing a program for generating a 3D axis, a horizontal curve and a key sectional sketch for the steel box beam; 4, utilizing the program for automatically completing overall erection of the steel box beam model; 5, selecting an optimal result for installation, and meanwhile, updating key data in real time in the installing process. Based on a BIM technology and numerical simulation, a wireless transmission technology is utilized for selecting key points whichcan reflect the actual state of the steel box beam and control the safety of the steel box beam, and thus internal force deformation of beam sheets in the hoisting process and stress change of structures in the hanging process are timely and accurately known. By analyzing monitored data and grasping the change rule, the whole process of hanging and installing the steel box beam is guided, and smooth proceeding of construction is ensured.

Description

technical field [0001] The invention relates to the field of municipal construction, in particular to a method for simulating a steel structure box girder. Background technique [0002] With the development of my country's iron and steel industry and steel structure technology, the number of steel structure municipal bridges is increasing. The box section has light weight, good overall performance, beautiful structure, high degree of industrial production, fast construction speed, and large clearance under the bridge. The advantages make the steel box girder structure widely used in the design and construction of municipal bridges. At the same time, the complexity of the municipal steel box girder construction environment, the diversity of functional requirements, and the large span have brought many technical problems to its fabrication, installation and construction that are different from the construction of railway and highway steel box girders. Among them, what is parti...
