Assembly type control point vertical projection measurement hole fixing device and using method thereof
The invention discloses an assembly type control point vertical projection measurement hole fixing device and a using method thereof. The assembly type control point vertical projection measurement hole fixing device is characterized by comprising a cover plate, wherein a projection measurement hole penetrates through the end face, facing a hole, of the cover plate; the projection measurement hole is located in the center of the plane of the cover plate; a plurality of through holes penetrate through the plane of the cover plate; the extending direction of the through holes is consistent with the extending direction of the projection measurement hole; screws are inserted into the through holes; the ends, away from the cover plate, of the screws are integrally connected with bent rods; the bent rods and the screws form L-shaped foundation bolts; the screws are in threaded connection with hand-screwed nuts; the hand-screwed nuts are butterfly nuts; the plane of the cover plate is square; the number of the through holes is four; and the four through holes are distributed in the four vertex angle positions of the plane of the cover plate respectively. By the adoption of the arrangement, on the premise that a protection device of the hole does not need to be moved away, the potential safety hazards such as step missing or falling of large objects are reduced, the effect of projection and paying-off of a control point can be achieved, the hole protection device can be recycled, and the beneficial effect of stable installation is achieved.
本发明公开了一种装配式控制点竖向投测洞口固定装置及其使用方法，其特征在于：包括朝向洞口的端面贯通有投测孔的盖板，投测孔位于盖板平面的中心位置，盖板的平面贯通有若干通孔，通孔的延伸方向与投测孔的延伸方向一致，通孔插接有螺杆，螺杆远离盖板的一端一体连接有弯折杆，二者形成L型地脚螺栓，螺杆螺纹连接有手拧螺母，该手拧螺母为蝶形螺母，盖板的平面呈正方形设置，通孔的数量为四个，四个通孔分别分布在盖板平面上的四个顶角位置。通过采用上述设置，在不需要移开洞口的防护装置的前提下，减少出现踩空或较大物件坠落等安全隐患，可以实现控制点投射放线的作用，且实现洞口防护装置的循环反复利用，且实现安装稳固的作用的有益效果。
