Bridge formwork intelligent design method based on BIM

Abstract

The invention discloses a bridge formwork intelligent design method based on BIM, and belongs to the field of BIM bridges, and comprises the following steps: 1) preliminary design: determining a bridge scheme and overall structure concepts, such as arrangement of a bridge plane, a vertical surface and a cross section, by professionals; and 2) technical design: carrying out integral and local structure refinement processing on the bridge scheme determined in the preliminary design. The bridge formwork intelligent design method provided by the invention has a powerful rapid modeling function. Abridge three-dimensional model can be quickly created according to a CAD construction drawing. The problem that traditional two-dimensional design expression is not perfect, visual and clear is solved, through design conflict analysis, possible problems in the bridge construction process are found in advance and solved in advance, the traditional management thought is changed, namely, passive management of a waiting problem is converted into active management of an active discovery problem, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of architectural engineering design, more specifically, to a BIM-based intelligent design method for bridge formwork. Background technique [0002] Scaffolding and formwork engineering is an important link in bridge engineering. In the process of project implementation, scaffolding is often arranged manually, which is inefficient, and there is no visual model as a reference before construction. For example, manual statistics are required after the plan and elevation are designed manually The amount of engineering, the preparation of calculation books and construction plans, the workload of designers is heavy and the design cost is high. [0003] Building Information Modeling (Building Information Modeling) is BIM technology, which refers to the computable information created and used in the process of building design and construction. It is a digital multi-dimensional information model of buildings. Many advantages, ...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a BIM-based intelligent design method for bridge formwork, which solves the problem that the formwork has not been used in my country for a long time, and there is a lack of relevant basis for its design and construction, which leads to construction failures. The work efficiency is low and problems continue during the process; secondly, the expression of two-dimensional drawings is not perfect, intuitive, and clear; thirdly, the calculation of engineering quantities is relatively cumbersome, and the modification process and after modification will greatly increase the workload; and if the design Improperness can easily lead to potential safety hazards and waste of materials; finally, due to the lack of team collaboration ability, for different special mold matching designs contained in the same project, if each team does not communicate in time, for complex node positions, it is common to have repeated designs. The situation reduces the efficiency of project design and construction
