带双梁的框架结构节能体系及其热工性能分析

对框架结构进行了改进,提出了一种带双梁的框架结构节能体系,并对该体系及其技术原理进行了介绍.用Fluent软件建立三维稳态传热模型,对梁、柱的热工性能进行了计算分析.结果表明:该体系与普通框架结构体系相比节能59%,梁、柱部分的热流量降低了79%,有效消除了梁、柱处的热桥影响,节能保温效果显著.因该体系大幅度减少结构冷热桥的出现,保证新型墙材的大面积使用,并且无须再做外墙内、外保温,避免了这些技术的诸多弊病,是一种更适合绿色生态节能建筑要求的新的结构体系.

Research on the Energy-efficient System and Thermal Performance of Frame Structure with Dual-beams

This research improved the frame structure and advanced the energy-efficient system of frame structure with dual-beams, whose principles were introduced. The thermal performances of the beams and columns were also analyzed with fluent software by building a three-dimensional steady thermal conduction model. The results have shown that this system is energy saving by 59%, compared with frame system. The heat flow of the beams and columns has been reduced by 79%, which indicates that this system has a distinct energy-saving effect. With the cold and hot bridges reduced and a large area of the new wall materials used, there is no need to build outside and inside insulation, whose shortages are avoided. Because of these, this new system better meets the requirements of green ecological energy-efficient buildings.
