Reinforcing and transforming method for low-strength concrete floor
The invention discloses a method for reinforcing and transforming a low-strength concrete floor. The method comprises the following steps: unloading a low-strength concrete slab; stripping a plate bottom concrete layer in the low-strength concrete plate, so that lower-layer steel bars in the original plate are exposed outside; newly-added plate steel bars are implanted below the lower-layer steel bars in the original plate; brushing an adhesion agent on the contact surface of the new and old concrete slabs; a hole is formed in the middle of the formwork, and a grouting material pouring valve is installed; a formwork is erected, a height-adjustable supporting mechanism is installed, and lifting supporting legs are arranged on the top of the height-adjustable supporting mechanism; arranging an infrared electronic ruler for monitoring the height of the template; grouting materials are poured through a grouting material pouring valve to reach the designed thickness; the liftable supporting legs are adjusted to enable the formworks to move upwards synchronously and integrally; removing the height-adjustable supporting mechanism; and a cutting machine is adopted to conduct leveling treatment on the newly-poured floor slab. The method can effectively solve the problem that the bearing capacity of the floor slab is greatly reduced due to the frosting phenomenon, existing decoration layers such as floor tiles do not need to be dismantled, the operation period is short, the effect is fast, and the construction technology is simple.
一种低强混凝土楼板的增强改造方法，对低强度混凝土板进行卸载；对低强度混凝土板中板底混凝土层进行剥离，使原板内下层钢筋暴露在外；在原板内下层钢筋下方植入新增板钢筋；新旧混凝土板接触面刷界面剂；在模板的中部开洞，并安装灌浆料浇注阀门；支设模板、安装高度可调节支撑机构，可调节支撑机构顶部具有可升降支腿；布置对模板高度进行监测的红外电子尺；通过灌浆料浇注阀门浇注灌浆料达到设计厚度；调整可升降支腿使模板同步整体上移；撤除高度可调节支撑机构；采用切割机对新浇筑的楼板进行整平处理。该方法能有效解决因起砂现象而造成楼板承载能力大幅度下降的问题，其不需拆除现有的地砖等装修层，其作业工期短、见效快、施工工艺简单。
