Problems solved by technology

[0005] Although the above method can achieve the goal of modeling, it is time-consuming, laborious, and error-prone, which obviously cannot meet the needs of designers for rapid modeling
[0006] Moreover, due to the special structure of the external closed stirrups of concrete bridge strip members, there is no related rapid modeling method

Embodiment

[0058] like Figure 1 to Figure 7 As shown, the computer-aided design method of the external closed stirrups of concrete bridge strip components; based on the CATIA software environment, and the concrete bridge components are modeled using the BIM model; in the BIM model of the concrete bridge components, multiple continuous intersections and The component surfaces that can form closed space graphics are used as the selected surface group, and the specific steps to generate closed stirrups are as follows:

[0059] Step 1. Offset the selected surface group according to the design cover thickness of the reinforcement, and the offset direction is to the inner side of the concrete bridge member;

[0060] Create multiple surfaces corresponding to multiple continuous surfaces in the selected surface group to form a steel bar datum face group, where multiple continuous surfaces in the steel bar datum face group are continuously intersected and form a closed space graphic structure; ...

Abstract

The invention discloses a computer-aided design method for an external closed stirrup of a concrete bridge strip-shaped component a plurality of continuously intersected component surfaces capable offorming a closed space graph are selected as selected surface groups for design in a BIM (Building Information Modeling) of the concrete bridge component based on a Dasso CATIA (Computer-aided Three-dimensional Interactive Application) software environment. The method comprises the following steps: firstly, selecting a reinforcing steel bar reference surface group, a reference line segment of a first closed stirrup in a configuration direction, a reference line segment of a tail end hook position, an initial auxiliary reinforcing steel bar surface and a reference auxiliary reinforcing steel bar plane; then, solving a closed stirrup datum line segment group by utilizing an intersection function in CATIA, and obtaining a center line of a first closed stirrup; solving the arrangement range ofthe closed stirrups and the number of the intervals of the closed stirrups; and finally, building a template for arranging closed stirrups in a certain direction on the surface of the concrete bridgecomponent in batches. By the application of the method, the closed stirrup model group in a certain direction can be quickly established on the surface of the concrete member.

Description

technical field [0001] The invention relates to the technical field of computer-aided design of concrete bridge components, in particular to a computer-aided design method for external closed stirrups of concrete bridge strip components. Background technique [0002] In the current BIM design software, there is a concrete component reinforcement modeling function for civil building structures, which can generate reinforcement models in batches for conventional components such as beams, slabs, and columns; there is also a concrete component reinforcement modeling function for small hydraulic structures. It can generate reinforcement models in batches for some simple shaped components. [0003] However, due to the differences in design methods and habits of civil building structures, hydraulic structures, and bridge structures, the above-mentioned related reinforcement modeling functions are not applicable. [0004] When bridge designers use the current BIM design software to...
