装配式住宅梁柱搭接方法及热桥被动节能技术研究

Prefabricated Beam-Column Lap Method and Passive Energy Saving Technology of Thermal Bridge

在传统居住建筑的梁柱搭接方法中,房柱与房梁之间通常采用牛腿衔接,传递来自房梁的荷载。该部分成为上部建筑结构中的薄弱部位,另外,牛腿需要较大的建筑空间,影响建筑外观^([1])。研究一种装配式被动节能的建筑搭接结构,包括房柱、房梁和楼板。通过所提供的装配式节能建筑搭接结构,牛腿与房柱一体成型,通过凹槽、凸起配合+螺栓固定的做法与房梁进行搭接,具有良好的结构稳固性和竖向承载力。同时在建筑热桥处理上也做了深入的研究,在关键节点上做了保温处理,阻断了热桥,具有保温节能的作用。

As the beam-column joint method in traditional residential buildings,the corbel connection is adopted usually between the room and pillar and beam to transfer load from the beam. This part becomes weak part of the upper structure of building. In addition,the corbel needs larger building space and affect the appearance of buildings^([1]). An assembly type of passive energy-saving building lap joint structure is studied,including columns,beams and slab. For the assembly type energy-saving building lap joint structure,the integrated corbel and column is overlapped to beam through a groove,a convex and bolt,with good structural stability and vertical bearing capacity. The treatment on thermal bridge is expounded,especially the heat treatment in key nodes,blocking the bridge,achieving thermal insulation and energy saving effect.
