Assembly type control point vertical projection measurement hole fixing device
The invention discloses an assembly type control point vertical projection measurement hole fixing device. The assembly type control point vertical projection measurement hole fixing device comprises a cover plate, wherein a projection measurement hole penetrates through the end face, facing a hole, 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 that 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 screws and the bent rods integrally form L-shaped foundation bolts; the ends, located at the cover plate and away from the bent rods, of the screws are in threaded connection with hand-screwed nuts; the hand-screwed nuts are butterfly nuts; the end face, close to the bent rods, of the cover plate is fixedly connected with a limiting plate; a working hole right opposite to the projection measurement hole penetrates through the limiting plate; and the cover plate covers the limiting plate. 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 missing of steps or falling of large objects are reduced, the effect of projection and paying-off of a control point can be achieved, and the beneficial effect that the hole protection device is recycled 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，包括朝向洞口的端面贯通有投测孔的盖板，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，螺杆和弯折杆一体形成L型地脚螺栓，螺杆位于盖板远离弯折杆的一端螺纹连接有手拧螺母，该手拧螺母为蝶形螺母，盖板靠近弯折杆的端面固定连接有限位板，限位板贯通有与投测孔正对的工作孔，盖板覆盖限位板设置。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的有益效果。
