胶合模板支撑体系优化设计与BIM研发

Plybamboo formwork supporting system optimization design and BIM research and development

为达到优化胶合模板支撑体系,节约胶合模板施工成本的目的,根据胶合模板支撑体系特点,结合优化理论提出胶合模板体系优化模型,以施工成本最低为目标,各支撑杆件承载力为约束条件,根据楼板尺寸,合理计算主、次肋及支撑间距.优化结果表明:传统的模板支撑体系设计过于保守,且没有考虑楼板尺寸对支撑体系设计的影响,胶合模板体系优化模型可以根据实际情况,合理选择支撑类型、优化设计支撑间距,可达到节约施工成本的目的.同时,开发了模板优化设计软件,使复杂的模板优化设计过程变得简单易操作,大大提高了设计者的工作效率,并与BIM技术相结合,利用BIM技术3D可视化、施工模拟等优势解决了设计图纸复杂,设计交底困难等问题,实现胶合模板设计、施工、管理的一体化.

On the purpose of optimizing plybamboo plybamboo forrnwork, according to characteristics of formwork supporting system, saving the construction cost of plybamboo formwork supporting system, plybamboo formwork system optimal model is put forward in combination with optimization theory, which could reasonably calculate the space of stringers, joists and shores, in order to reach the aim of meeting the requirement of saving construction cost under the condition of bearing capacity. Optimization result shows that the traditional design method is more conservative, it ignores the influence of floor size on support system. The optimization model that built in this paper could select the type of support and design the space of support reasonably, so that the construction cost could be saved. The optimization design software is developed to make the complex design optimal process become easy to operate, greatly improving the efficiency of the designers＇ work, and combined with BIM technology,which has the advantages of 3D visualization and simulation of construction, to solve the problem of complex design drawings and design clarifying difficultly, finally realize the integration of formwork design, construction and management.
