Description

Technical Field

[0001] The utility model relates to the technical field of building drilling protection devices, in particular to a building drilling protection device. Background Art

[0002] During the construction of the building structure, technicians need to drill holes at fixed positions on the foundation floor to pave the way for subsequent pipeline construction. The sizes of these holes range from large to small. After the drilling is completed, users need to fill these holes with fillers to avoid blockages caused by subsequent construction and to prevent falling objects and casualties.

[0003] At present, some cloth or plastic bags are usually used for filling. In the later construction process, the cement and other lime produced will accumulate on them, which makes it difficult for the users to find them when they open the holes again, affecting the later construction. At the same time, when subjected to certain external forces, these fillers are easy to fall off, resulting in the holes being exposed, which poses certain safety hazards. Utility Model Content

During the rotation of the forward and reverse screw rods 3, the two threaded blocks 4 are driven away from each other, and the arc-shaped opening plates 6 connected to the push rods 5 are pushed away from each other by the threaded blocks 4. The arc-shaped opening plates 6 are pressed against the inner wall of the pit 2, thereby protecting the pit 2 and preventing the pit 2 from being exposed to the outside and causing accidents. During the lateral movement of the arc-shaped opening plate 6, the T-shaped block 11 installed on the top of the arc-shaped opening plate 6 slides in the C-shaped groove 12, thereby improving the stability of the lateral moving arc-shaped opening plate 6.
