Problems solved by technology

The technology of bridge steel formwork to make curved bridges is relatively mature. As long as the formwork is formed according to the curve of the bridge, the difficulty of later construction will be reduced accordingly. However, the steel formwork has no value of repeated use, and the economic and social benefits are small

Embodiment Construction

[0038] The implementation of the present invention is described below through specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0039] A curved bridge formed by BIM-based combined formwork support technology ( figure 2 Shown is the method for curved bridge structure schematic diagram of the present invention), comprises the following steps:

[0040] 1) Calculation: Calculate and determine the distance between the supporting structures according to the self-weight of the bridge structure and the weight of the supporting system;

[0041] 2) Modeling: According to the calculated actual distance, the bridge is built on the computer based on BIM technology, combined with the bridge

[0042] For special curves and formwork support special construction schemes, see formwork support and formwork dimensions image 3 ;

[0043] 3) Cutting: combined w...

Abstract

The invention discloses a method for forming a curve bridge based on BIM by adopting a combined template support process of a customized arc-shaped steel pipe and a flexible template. The method comprises the steps of BIM-based modeling, blanking, encoding, mold splicing and mold release oil brushing. Based on application of the BIM technology, steel pipe waste in the arc-shaped steel pipe manufacturing process is reduced, the manufacturing accuracy of the radian of each steel pipe is improved, and the method has the advantages that the operation procedure is simple, the construction period isremarkably shortened, the engineering cost is reduced, the construction speed is high, and the application range is wide.

Description

technical field [0001] The invention relates to a method for forming a curved bridge based on BIM using a combined formwork support process, more specifically, a method for forming a curved bridge based on BIM using a combined formwork support process of custom-made curved steel pipes and flexible formwork. Background technique [0002] With the process of urbanization and the continuous improvement of people's aesthetics, the planar form of bridges is constantly updated. The plane shape of auxiliary bridges in many projects is curved, with up and down slopes, and the corner radius of the wing is very small. The practical significance of using wooden formwork no longer exists, and it is impossible to make a curved shape with ordinary wooden formwork. [0003] There are only two forms of formwork left: steel formwork and bamboo plywood. The technology of bridge steel formwork to make curved bridges is relatively mature. As long as the formwork is formed according to the curv...
