基于BIM技术的房建梁柱节点配筋优化和成本研究

Optimization of reinforcement and cost research for building beam and column nodes based on BIM technology

以天津生态城南部片区15号地块公屋二期2C期项目梁柱节点钢筋稠密的房建工程实践为例开展分析,该工程绑扎钢筋空间狭小导致时常出现钢筋绑扎间距不合规范要求,并容易出现梁柱钢筋碰撞、钢筋数量和设计数值不匹配、钢筋具有较高损耗率且加工措施十分烦琐等问题。为此,文章结合BIM技术和精益建造技术,依托Revit构建梁柱节点三维模型并对梁柱节点进行参数化分析,优化钢筋配置,有效解决了钢筋避让等施工重难点,同时BIM技术的应用能够辅助开展钢筋智能化加工,有效提高钢筋加工速率的同时也降低了生产损耗,具有广泛的应用价值。

Taking the example of the construction project of densely reinforced beams and columns in Phase 2C of Block 15 public housing in the southern area of Tianjin Eco-city, this analysis highlights various challenges. The limited space for reinforcing bar binding in the construction process often leads to non-compliance with spacing regulations, resulting in issues such as collisions between beam and column reinforcement, discrepancies in the quantity of reinforcement, and complex processing procedures with a high rate of wastage. To address these challenges, a combination of BIM(Building Information Modeling) technology and lean construction techniques was employed. Leveraging Revit, a three-dimensional model of the beam-column nodes was constructed, and parametric analysis was conducted to optimize the reinforcement layout. This approach effectively resolved construction difficulties, including reinforcement clashes and clearance issues. Additionally, the application of BIM technology assisted in achieving intelligent reinforcement processing, improving processing efficiency, and reducing production losses. The utilization of BIM not only addressed construction challenges but also demonstrated significant value in enhancing productivity and reducing material wastage.
