| 摘 要： | 当楼板混凝土强度较低时 ,粘钢加固法、粘贴碳纤维布加固法已不能使用 ,如将楼板砸掉重新浇筑 ,加固范围又比较大 ,支承楼板的墙体也将无法保留。结合实际工程 ,提出了开槽设暗梁的楼板加固方法 ,避免了全部拆除重建

| Abstract: | When the concrete compressive strength of a floor slab is lower, the adhesive steel plate or CFRP can not be used for strengthening it. If we demolish the floor slab and place concrete again, the strength area is larger, the wall of bearing floor slab will not be kept. The strengthening method of digging groove and increasing hidden beam is proposed by combining an actual project, which avoids all of demolition and restitution. |
