Fixing structure for insulation boards of upper bay window and lower bay window

The invention relates to the technical field of building outer wall heat preservation construction, in particular to an upper bay window heat preservation plate fixing structure and a lower bay window heat preservation plate fixing structure. The heat preservation structure comprises a plurality of heat preservation nails which are vertically inserted into a heat preservation plate from the outdoor side, the tail portions of the heat preservation nails extend into steel bar frameworks of the upper bay window and the lower bay window, and the tail portions of the heat preservation nails are bent and hooked and tied to the steel bar frameworks. The fixing effect of the heat preservation nail on the heat preservation plate is enhanced, and the probability that the heat preservation nail is partially pulled out of the heat preservation plate is reduced. 本申请涉及建筑外墙保温施工的技术领域，尤其是涉及一种上、下飘窗保温板固定结构。其包括若干从室外侧垂直插入保温板的保温钉，所述保温钉的尾部伸入上、下两个飘窗的钢筋骨架的内部，且若干所述保温钉的尾部均弯折并均与钢筋骨架钩挂拉结。本申请具有增强保温钉对保温板的固定作用，降低保温钉从保温板内部分拔出的概率的效果。
