Description

Technical Field

[0001] The utility model relates to the technical field of stair safety, in particular to a stair safety protection net. Background Art

[0002] Stairs refer to a building component composed of continuous steps, platforms and enclosing structures for transportation between floors. In the field of stair construction, during the construction process of stairs, in order to prevent outsiders from entering the unfinished stairs and falling and other injuries, a safety net must be set at the stair entrance to intercept outsiders. Therefore, a stair safety net is needed.

[0003] For this purpose, a Chinese patent with announcement number CN217871941U discloses a construction stair safety net, including a net body and a wall, wherein the outer wall of the net body is fixedly connected with a first fork, the outer wall of the net body is fixed with a second fork, and the inner wall of the first fork is slidably connected with a first horizontal axis. During the installation of the construction stair safety net, the universal wheel at the bottom is first used to move the net body to the installation position, and then the first block is aligned with the reserved groove at the stair entrance, and then the second support body is pulled to the right. After the second support body is subjected to force, it moves with the connecting rod, and when the connecting rod moves, it slides with the first horizontal axis in the first fork, and when the connecting rod moves, it slides with the second horizontal axis in the second fork. At this time, the angle between the connecting rods becomes smaller, and the second support body begins to move to the right until the right outer wall of the second support body contacts the wall surface.

[0004] However, in this patent, since the left and right sides of the staircase are fixed by aligning the first clamping block with the reserved groove at the stair entrance and the second clamping block tightly against the reserved groove on the right wall, the top and bottom are still not fixed to the ground, which may make it fix unreliably and reduce its safety protection effect. In addition, in this patent, since the protective net body and its other structures are integrated, when it needs maintenance and when the protective net body needs to be cleaned during the maintenance, the protective net body cannot be removed separately, so it needs to be cleaned as a whole, which increases the objects to be cleaned and increases the difficulty of maintenance.
