Of course, three or more frames 2 may be used, and then the frames 2 located in the middle portion may be connected to the adjacent frames 2 through the telescopic rods 4 on both sides, and finally, after all the telescopic rods 4 are fixed, stable connection of a plurality of frames 2 may be achieved.

In summary, in the construction process of the main structure of the building engineering, the application is applicable to the horizontal protection of the elevator horizontal holes 1 and the stair horizontal holes 1 with different sizes of the working layer, and the telescopic rods 4 are used for connecting a plurality of frames 2, so that the frames 2 can be stably connected, and the distance between two adjacent frames 2 can be adjusted, thereby ensuring that the horizontal holes 1 with different width types can be applicable and the holes in the width direction can be covered. And in the length direction of the horizontal opening 1, a plurality of groups of protection facilities of the application can be arranged, so that the opening in the length direction is covered. Meanwhile, a protection flat plate 3 is further erected on the frame 2, so that a stable surface support can be provided for walking of personnel. Therefore, the protective facility arranged in the mode can be assembled and spliced on the ground according to the size of the horizontal hole 1, and has the advantages of convenience in erection, strong applicability, high turnover rate, low construction cost and good protective effect.

In addition, because a certain interval may appear in the telescopic process of the adjacent frames 2, the protective turning plate 5 is additionally arranged on the protective flat plate 3, the protective turning plate 5 is positioned on the side edge of the protective flat plate 3, the side edge is a side edge close to the adjacent protective flat plate 3, after the protective turning plate 5 turns over, the interval between the adjacent frames 2 can be covered, so that the adjacent frames are lapped on the protective flat plate 3 or the telescopic rod 4 between the two frames 2, surface support is provided for the interval at the position, and the frames 2 are ensured to have a larger supporting area.

For the telescopic adjustment of the telescopic rod 4, please refer to fig. 2, a plurality of bolt holes 23 are distributed on the side wall of the short square tube 22 along the length direction thereof, meanwhile, a locking hole 41 may be formed on the telescopic rod 4, the bolt 8 penetrates through the bolt holes 23 and the locking hole 41 to fix the telescopic rod 4 inside the short square tube 22, and the locking hole 41 corresponds to different bolt holes 23 according to different extending positions of the telescopic rod 4, thereby realizing the telescopic function of the telescopic rod 4 relative to the two frames 2.

In order to further improve the safety of the protection arrangement laid on the horizontal opening 1, when a plurality of frames 2 are fixedly connected through telescopic rods 4, and the formed integral structure is laid above the horizontal opening 1, two frames 2 positioned at the outermost side are respectively overlapped with two opposite sides of the horizontal opening 1. Thereby ensuring that both sides of the protection facility have a certain supporting width on the horizontal hole 1 and improving the safety of the protection facility.
