Problems solved by technology

[0003] (1). It is a huge workload for experienced rebar samplers to manually turn over samples;
[0004] (2). With the help of rebar remodeling software such as Glodon and Luban, etc., but because the software is mainly aimed at components in the field of housing construction, and is based on 2D CAD drawings, once the model is established, it cannot be modified, and problems occur. The collision situation is difficult to adjust, and the applicability to heterogeneous components such as bridges and tunnels is poor;
[0005] (3). Use conventional 3D modeling software to directly create steel bar models based on design drawings in the 3D structural model. The disadvantage is that the design drawings do not include information on steel bar joints, and the position and form of joints in the steel bar model cannot be automatically created. Manual modeling The efficiency is low, and an accurate bill of materials cannot be formed, so it has little significance for on-site construction guidance
[0006] Therefore, for some complex structures, it is still necessary to use experienced workers with rich reinforcement experience to complete the detailed drawings based on experience, and the work efficiency is low; at the same time, the two-dimensional reinforcement diagram is not fully expressed, which further increases the difficulty of specific construction

Embodiment Construction

[0022] Such as figure 1 As shown, a 3D rebar flip method based on BIM technology, the specific implementation steps are as follows:

[0023] (1). For special-shaped components, the solid model of concrete components built by conventional 3D modeling software (CATIA, REVIT, 3DMAX, etc.) can be imported, and then the design reinforcement modeling is carried out; for standard components, concrete components can be automatically generated according to the design parameters Solid models, including design reinforcement models. The thickness, size, and specifications of the protective layer of steel bars are all parameterized settings, which can be dynamically updated according to design requirements.

[0024] (2). According to the national building standard design atlas and the component details provided by the design unit and the overlapping form of the steel bars, and combined with the fixed length of the steel bars (6, 9, 12 meters), set the steel bar joint form and the lap join...

Abstract

The invention relates to a three-dimensional reinforcing steel bar lofting method. The three-dimensional reinforcing steel bar lofting method includes the specific steps that 1, a concrete member solid model is generated through three-dimensional modeling software, 2, the types and the lap joint lengths of reinforcing steel bar connectors are preset according to the design and standard requirements for reinforcing steel bars; 3, the types and the number of the connectors are automatically calculated according to the positions of the reinforcing steel bars and the selected types of the connectors, and corresponding connector type models are generated at the lap joint positions of the reinforcing steel bars; 4, after the positions of the connectors are partially adjusted, the related positions of the connectors and the whole model are automatically updated through refreshing; meanwhile, generation of three-dimensional or two-dimensional material lists are supported, and the statistics of the quantity of reinforcing steel bars is carried out in real time. By means of the three-dimensional reinforcing steel bar lofting method, blanking in the three-dimensional model mode can be achieved; as for complex members, observation can be carried out in any direction, any sectioning can be carried out, and a reinforcing steel bar arrangement person can conveniently learn drawings; due to consideration of the positions of the reinforcing steel bar connectors, calculation of the construction quantity can be sufficiently achieved, project cost is saved, and workloads are reduced.

Description

technical field [0001] The invention relates to a computer-aided design in building construction, in particular to a three-dimensional steel bar flipping method in building construction. Background technique [0002] As one of the main building materials, steel bars have always been the focus and difficulty of cost control for construction units. Conventional rebar sampling and blanking are carried out based on the two-dimensional drawings issued by the design unit for deepening and statistics. There are three commonly used methods: [0003] (1). It is a huge workload for experienced rebar samplers to manually turn over samples; [0004] (2). With the help of rebar remodeling software such as Glodon and Luban, etc., but because the software is mainly aimed at components in the field of housing construction, and is based on 2D CAD drawings, once the model is established, it cannot be modified, and problems occur. The collision situation is difficult to adjust, and the appli...
