Concrete strength detection method for cast-in-place concrete floor
The invention relates to a concrete strength detection method for a cast-in-place concrete floor. The concrete strength detection method comprises the following steps: S1, positioning: setting out anddetermining a measuring point, and installing at least two positioning lines on the side template of the periphery support of the floor, so that the intersection of the positioning lines is a measuring point; s2, installation of an anchoring part: after concrete is poured into the space defined by the side formworks arranged around the floor slab, inserting the anchoring part into the concrete inthe vertical direction, wherein one end of the anchoring part is located in the concrete, and the other end of the anchoring part is located outside the concrete; s3, installation of a pull-out instrument; after concrete curing is completed, installing a pull-out instrument at the end, located outside the concrete, of the anchoring part; s4, drawing of the concrete; starting the pulling-out instrument to apply pulling force to the anchoring part, and recording the pulling force value measured by the pulling-out instrument. In the invention, the positioning lines are arranged to position the measuring points, and therefore the installation position of the anchoring part can be conveniently determined after concrete pouring is completed.
本发明涉及一种现浇砼楼板的混凝土强度检测方法，包括如下步骤：S1，定位；放样并确定测量点；在楼板周边支护的侧模板上安装定位线，定位线设置至少两根，使得定位线的交叉处为测量点；S2，安装锚固件；在楼板周围设置的侧模板所围成的空间内浇筑混凝土后，将锚固件沿竖直方向插入到混凝土中，使得锚固件一端位于混凝土内部，另一端位于混凝土外部；S3，安装拔出仪；待混凝土养护完成后，在锚固件位于混凝土外部的一端安装拔出仪；S4，拉拔混凝土；启动拔出仪对锚固件施加拉力，并记录拔出仪测得的拉力数值。本发明设置定位线对测量点进行定位，从而在混凝土完成浇筑后便于确定锚固件的安装位置。
