[0029] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Please see attached Figure 1 and attached Figure 2 An adjustable horizontal opening protection device comprises a pair of protection units symmetrically arranged at a horizontal opening 101 of a floor slab 1, each group of protection units comprises a protection plate 2 and an adjustment clamping mechanism; the protection plates 2 of a pair of protection units respectively cover the horizontal openings 101 of the floor slab 1, and adjustment grooves 201 are respectively formed on the side portions of the pair of protection plates 2 close to each other, and the adjustment clamping mechanism vertically penetrates the protection plates 2 and the floor slab 1 through the adjustment grooves 201 and the horizontal opening 101, and the adjustment clamping mechanism abuts against the top surface of the protection plate 2 and the bottom surface of the floor slab 1, so that the protection plate 2 is locked on the floor slab 1, and the pair of protection plates 2 are spliced ​​to form a protection plate body and cover and close the horizontal opening 101.

[0031] The adjusting clamping mechanism passes through the protective plate 2 and the floor slab 1. At the same time, the adjusting clamping mechanism forms two upper and lower opposite clamping forces by abutting against the top surface of the protective plate 2 and the bottom surface of the floor slab 1. It can not only lock and fix the protective plate 2 on the floor slab 1, but also adapt to floor slabs 1 of different thicknesses.

[0032] A pair of protective units are arranged roughly symmetrically, and are convenient and quick to disassemble and assemble. The splicing of a pair of protective plates 2 can effectively cover and protect horizontal openings 101 of different sizes. Preferably, the protective plates 2 can be made of 600*300*5mm steel plates, which have high strength and ensure the protective effect. At the same time, the size after splicing is large, which can adapt to the size of the current conventional horizontal openings 101.

[0033] Please see attached Figure 3 To Attachment Fig. 9 The adjustable clamping mechanism includes a clamping adjustment member 3, a clamping rod 4 and a clamping fixing member 5. The clamping rod 4 vertically penetrates the protective plate 2 and the floor slab 1 through the adjustment groove 201 and the horizontal hole 101. The clamping adjustment member 3 is adjustably arranged on the clamping rod 4 and can abut against the top surface of the protective plate 2. The clamping fixing member 5 is arranged at the bottom of the clamping rod 4 and can abut against the bottom surface of the floor slab 1.

[0034] By moving the clamping adjustment member 3 up and down along the clamping rod 4, the distance between the clamping adjustment member 3 and the clamping fixing member 5 can be adjusted, so that the clamping adjustment member 3 presses against the top surface of the protective plate 2, and the clamping fixing member 5 presses against the bottom surface of the floor 1, thereby ensuring the locking and fixing effect of the protective plate 2 on the floor 1 of different thicknesses, and having good versatility.

[0035] The clamping rod 4 is a screw rod, and the clamping adjusting member 3 is a nut matching the screw rod, so that the clamping adjusting member 3 can be rotatably adjusted on the clamping rod 4 .

[0036] Preferably, the clamping rod 4 can be made of a steel pipe with a length of 200 mm and a diameter of 20 mm, and the outer part of the steel pipe is threaded to form a hollow screw. The clamping adjustment member 3 can be made of a nut with an inner diameter of 22 mm and an outer diameter of 50 mm, which is used to match and screw with the thread of the screw.

[0037] By rotating the nut clockwise or counterclockwise, the nut can be moved up and down relative to the screw rod, thereby adapting to floor slabs 1 of different thicknesses.

[0038] Please see attached Figure 1 and attached Figure 2 The outer diameter of the nut is larger than the width of the adjusting groove 201 , and the diameter of the screw is slightly smaller than the width of the adjusting groove 201 , so that the bottom surface of the nut can fit tightly against the top surface of the protective plate 2 , and the screw can pass through the adjusting groove 201 .

[0039] Preferably, the width of the adjustment slot 201 can be set to 24 mm, which is convenient for the screw to penetrate and move, and the screw is not easy to slide and deviate in the adjustment slot 201 after locking. The outer diameter of the nut is larger than the width of the adjustment slot 201, ensuring that the nut has sufficient contact and tightening area on the top surface of the protective plate 2, thereby ensuring the locking effect of the protective plate 2.

[0040] Please see attached Figure 6 To Attachment Figure 8 A screw hole (not shown in the figure) is formed at the bottom of the clamping rod 4, and the clamping fixture 5 is a bolt matching the screw hole, so that one end of the clamping fixture 5 is threadedly screwed into the screw hole at the bottom of the clamping rod 4, and the other end of the clamping fixture 5 abuts against the bottom surface of the floor slab 1.

[0041] Preferably, the diameter of the screw hole is 12 mm, the diameter of the bolt is 10 mm, the diameter of the bolt head is 20 mm, and the length of the bolt is 80 mm. The bolt is screwed into the screw hole to ensure that the bolt is fixed at the bottom of the clamping rod 4 and will not fall off.

[0042] The length of the bolt is longer than the diameter of the clamping rod 4, so that the other end of the bolt can extend longer to the outside of the clamping rod 4, so that the other end of the clamping fixture 5 can abut against the bottom surface of the floor 1, thereby ensuring the locking effect of the protective plate 2 on the floor 1.

[0043] Please see attached Fig. 9 The axial direction of the clamping fixture 5 is perpendicular to the axial direction of the clamping rod 4, which can ensure the locking effect of the protective plate 2 on the floor slab 1 to the greatest extent.

[0044] Please see attached Figure 1 and attached Figure 2 The length direction of the adjustment slot 201 is consistent with the width direction of the horizontal hole 101, and the length of the adjustment slot 201 is not less than half of the width of the horizontal hole 101, ensuring that each set of adjustment clamping components has a sufficient adjustment range to meet the use requirements at horizontal holes 101 of different sizes.

[0045] Please see attached Figure 1 and attached Figure 2 The length of the protective plate 2 is not less than the length of the horizontal opening 101, and the width of the protective plate 2 is greater than the width of the adjustment groove 201, ensuring that the protective plate 2 has sufficient overlapping width on the floor slab outside the horizontal opening 101, thereby ensuring the locking effectiveness and stability of a pair of protective plates 2, not easy to fall off, and improving the protection effect.

[0046] The width of the adjustment slot 201 is relatively small, and hardly affects the protective effect of the pair of protective plates 2 on the horizontal opening 101 .

[0047] Please see attached Figure 1 To Attachment Fig.11 , the installation method of the utility model is:

[0048] According to the size of the horizontal opening 101, a steel plate of appropriate size is selected as the protective plate 2, and an adjustment slot 201 is opened according to the adjustment range. According to the thickness of the floor 1, a screw rod of appropriate length is selected as the clamping rod 4, and a nut matching the screw rod is used as the clamping adjustment part 3.

[0049] A pair of protective plates 2 are laid at the horizontal opening 101 , and the pair of protective plates 2 are roughly symmetrically arranged about the center line of the horizontal opening 101 , so that the overlapping range of the pair of protective plates 2 and the floor slab 1 outside the horizontal opening 101 is roughly the same, ensuring that the pair of protective plates 2 are evenly stressed.

[0050] According to the width of the horizontal opening 101, the position of the clamping rod 4 is adjusted along the adjustment slot 201, so that the other end of the clamping fixture 5 moves to the bottom of the floor 1. The clamping rod 4 is pulled upward, so that the other end of the clamping fixture 5 abuts against the bottom surface of the top-tightening floor 1. The clamping adjustment member 3 is screwed downward through the thread, so that the bottom surface of the clamping adjustment member 3 abuts against the top surface of the top-tightening protective plate 2, and the protective plate 2 is locked and fixed on the floor 1.

[0051] The protective plates 2 of a pair of protective units are fixed on the floor 1 in the same manner, which will not be described one by one here. The pair of protective plates 2 are spliced ​​to form a protective plate body, and the horizontal hole 101 is covered by the protective plate body to achieve an effective protective effect.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
