Description

Technical Field

[0001] This utility model relates to the technical field of building fall protection equipment, and in particular to a building fall protection device. Background Technology

[0002] Building construction fall prevention refers to a series of safety measures and equipment used during building construction to prevent workers from falling from heights. This is a crucial aspect of ensuring the safety and health of construction workers. During building construction, the edges of newly built staircases may not be equipped with guardrails in a timely manner, posing a risk of workers falling while walking on the stairs.

[0003] Chinese utility model patent with publication number CN220036211U discloses a protective device for the exposed edge of a staircase at a construction site. It includes at least two support mechanisms clamped at the exposed edge of the staircase and a protective railing assembly connected to the at least two support mechanisms. The support mechanism includes a support plate, an upper clamping plate, a lower clamping plate, and a pressing plate. The upper clamping plate is an L-shaped clamping plate, and the vertical side plate of the L-shaped clamping plate is installed on the support plate. A sleeve is installed at the center of the top surface of the horizontal plate. The lower clamping plate includes a trapezoidal side plate and a bottom plate. The protective railing assembly includes a vertical post, an inclined railing, and a horizontal railing connected to one end of the inclined railing through an L-shaped sleeve. A protective plate is connected between the support plates of two adjacent support mechanisms. The structure is relatively complex, cannot be folded, and is inconvenient for storage, placement, and transportation. Moreover, its application scenario is limited, and it can only protect staircases with fixed slope and fixed thickness. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a building fall prevention device that can quickly install temporary guardrails on the side of newly built stairs and has high safety.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes two clamping plate assemblies. The clamping plate assembly includes an upper clamping plate, a lower clamping plate that guides and cooperates with the rear section of the upper clamping plate, and at least two locking members that are threadedly engaged with the lower pressure plate for adjusting the height. The upper clamping plate and the lower clamping plate cooperate to form a limiting space for clamping the inclined surface of the staircase; a width adjusting member, which is detachably connected between the two upper clamping plates; a guard rod, which is detachably connected to the upper part of the upper clamping plate; the width adjusting member, which is detachably connected between the two upper clamping plates; and the guard rod, which is detachably connected to the upper part of the upper clamping plate.

[0006] Furthermore, a connecting plate is provided at the rear section of the upper clamping plate, the connecting plate having at least two openings that guide and cooperate with the lower clamping plate, and an mounting sleeve is provided on the upper surface of the upper clamping plate, with a positioning sleeve in the middle of the mounting sleeve for threaded engagement of a locking screw.

[0007] Furthermore, the rear section of the lower clamping plate is fixedly connected with at least two threaded rods, each threaded rod corresponding to and engaging with the corresponding opening guide, and each threaded rod engaging with the locking member threadedly. The front section of the lower clamping plate forms an inclined surface that engages with the inclined surface at the bottom of the staircase.

[0008] Furthermore, the angle of the inclined surface is 30-50 degrees.

[0009] Furthermore, a rubber pad is guided and connected to the lower surface of the upper clamping plate along the length direction. The rubber pad is provided with a plurality of rubber heads for insertion. The lower surface of the upper clamping plate is formed with a reserved hole corresponding to the guide and fit of the corresponding rubber head.

[0010] Furthermore, the upper surface of the upper clamping plate is provided with an ear plate, and a through hole is opened in the middle of the ear plate. The width adjustment component includes an internal threaded sleeve, two screws and two locking nuts. Each screw is threadedly engaged with one end of the internal threaded sleeve. Each screw passes through the corresponding through hole and is threadedly connected to the corresponding locking nut. Each locking nut is limitedly engaged with the corresponding ear plate.

[0011] The beneficial effects of this utility model are: This utility model can adjust the length of the two screws in the internal threaded tube according to the width of the upper surface of the stair step, thereby increasing or decreasing the distance between the two upper clamping plates. When the distance between the two upper clamping plates meets the requirement of the width of the upper surface of the stair step, the relative position of the screws and the lugs is restricted by the two nuts, so that the relative position of the two upper clamping plates is restricted, which is suitable for the needs of stair steps of different widths.

[0012] Place the lower clamping plate on the slope at the bottom of the stairs, so that the inclined surface of the lower clamping plate fits against the slope at the bottom of the stairs. Then, use the clamping nut and threaded rod to restrict the relative position of the connecting plate and the lower clamping plate. At this time, the limiting space formed by the upper clamping plate, the lower clamping plate and the connecting plate are clamped and fixed on the stairs. The guardrail is located at the edge of the stairs. Use cross buckles to install the guardrail tube, forming a guardrail structure at the edge of the newly built stairs, improving safety.

[0018] like Figures 1 to 4 As shown, in this embodiment, the present invention includes two clamping plate assemblies 1, each clamping plate assembly 1 including an upper clamping plate 11, a lower clamping plate 12 that guides and cooperates with the rear section of the upper clamping plate 11, and at least two locking members 13 that are threadedly engaged with the lower clamping plate 12 for adjusting height. The upper clamping plate 11 and the lower clamping plate 12 cooperate to form a limiting space 14 for clamping the inclined surface of the staircase; a width adjusting member 2, which is detachably connected between the two upper clamping plates 11; and a protective rod 3, which is detachably connected to the upper part of the upper clamping plate 11.

[0019] According to the width of the upper surface of the stair step, adjust the length of the two screws 22 in the internal thread tube, thereby increasing or decreasing the distance between the two upper clamping plates 11. When the distance between the two upper clamping plates 11 meets the requirement of the width of the upper surface of the stair step, use two nuts to restrict the relative position of the screws 22 and the lugs, so that the relative position of the two upper clamping plates 11 is restricted, which is suitable for the needs of stair steps of different widths.

[0020] Place the lower clamping plate 12 on the inclined surface at the bottom of the stairs. At this time, the inclined surface 4 on the lower clamping plate 12 is in contact with the inclined surface at the bottom of the stairs. Then, use the locking piece 13 and the threaded rod 19 to adjust the thread to control the relative position of the connecting plate 15 and the lower clamping plate 12. At this time, the limiting space 14 formed by the upper clamping plate 11, the lower clamping plate 12 and the connecting plate 15 is clamped and fixed on the stairs. At this time, the guardrail 3 is located at the edge of the stairs. Use the cross buckle to install the guardrail on the guardrail 3 to form a guardrail structure at the edge of the newly built stairs, thereby improving safety.

[0021] In this embodiment, a connecting plate 15 is provided at the rear end of the upper clamping plate 11. The connecting plate 15 has at least two openings 16 that guide and cooperate with the lower clamping plate 12. An mounting sleeve 17 is provided on the upper surface of the upper clamping plate 11. A positioning sleeve 18 for threaded engagement of a locking screw is provided in the middle of the mounting sleeve 17.

[0022] The lower end of the protective rod 3 is installed in the mounting sleeve 17 by a locking screw. A positioning sleeve 18 is installed on the outer surface of the upper end of the mounting sleeve 17. The positioning sleeve 18 communicates with the internal space of the mounting sleeve 17, so that the locking screw is threadedly connected in the positioning sleeve 18. Tightening the locking screw makes one end of the locking screw contact the surface of the protective rod 3, thus completing the assembly of the protective rod 3 and the mounting sleeve 17.

[0023] In this embodiment, at least two threaded rods 19 are fixedly connected to the rear section of the lower clamping plate 12. Each threaded rod 19 corresponds to a guide engagement with a corresponding opening 16, and each threaded rod 19 is threadedly engaged with the locking member 13. The front section of the lower clamping plate 12 forms an inclined surface 4 that engages with the inclined surface at the bottom of the staircase. The threaded rods 19, in conjunction with the locking member 13, control the distance between the upper clamping plate 11 and the lower clamping plate 12 through the threads, so that the lower clamping plate 12 is placed on the inclined surface at the bottom of the staircase, at which time the inclined surface 4 on the lower clamping plate 12 is in contact with the inclined surface at the bottom of the staircase.

[0024] In this embodiment, the angle of the inclined surface 4 is 30-50 degrees. The inclined surface 4 is designed to facilitate a tighter fit between the lower clamping plate 12 and the lower inclined surface of the stairs, thereby providing greater clamping force and further improving safety.

[0025] In this embodiment, a rubber pad 5 is guided and connected to the lower surface of the upper clamping plate 11 along its length. The rubber pad 5 is provided with a plurality of rubber heads 6 for insertion. The lower surface of the upper clamping plate 11 has pre-drilled holes corresponding to the guide fit of the respective rubber heads 6. An interference fit is used between the rubber heads 6 and the pre-drilled holes, which increases the friction force and improves the safety of use during the clamping process of the upper clamping plate 11 and the lower clamping plate 12.

[0026] In this embodiment, the upper surface of the upper clamping plate 11 is provided with an ear plate 7, and a through hole 71 is opened in the middle of the ear plate 7. The width adjusting component 2 includes an internal threaded sleeve 21, two screws 22, and two locking nuts 23. Each screw 22 is threadedly engaged with one end of the corresponding internal threaded sleeve 21. Each screw 22 passes through the corresponding through hole 71 and is threadedly connected to the corresponding locking nut 23. Each locking nut 23 is limitedly engaged with the corresponding ear plate 7. A support plate is provided on one side of the ear plate 7. When the screw 22 is connected, it passes through the support plate of the ear plate 7 and is threadedly engaged with the locking nut 23. Because there is a gap between the support plate and the ear plate 7, when the locking nut 23 and the screw 22 cannot be properly separated due to corrosion, the part of the screw 22 between the support plate and the ear plate 7 can be cut off with a hacksaw blade, which facilitates the reuse of the upper clamping plate 11 and other structures.

[0027] The working principle of this utility model:

[0028] The length of the two screws 22 inside the internal threaded tube can be adjusted according to the width of the upper surface of the stair step, thereby increasing or decreasing the distance between the two upper clamping plates 11. When the distance between the two upper clamping plates 11 meets the requirement of the width of the upper surface of the stair step, the relative position of the screws 22 and the ear plate 7 is restricted by the two nuts, so that the relative position of the two upper clamping plates 11 is restricted.

[0029] Adjust the height of the limiting space 14 between the upper clamping plate 11 and the lower clamping plate 12 by rotating the locking part 13, so that the lower clamping plate 12 is placed on the inclined surface at the bottom of the stairs. At this time, the inclined surface 4 on the lower clamping plate 12 is in contact with the inclined surface at the bottom of the stairs, thus completing the installation and fixing of the clamping plate assembly 1 to the stairs.

[0030] The lower end of the protective rod 3 is installed in the mounting sleeve 17 by a locking screw. A positioning sleeve 18 is installed on the outer surface of the upper end of the mounting sleeve 17. The positioning sleeve 18 communicates with the internal space of the mounting sleeve 17, so that the locking screw is threadedly connected in the positioning sleeve 18. Tightening the locking screw makes one end of the locking screw contact the surface of the protective rod 3, thus completing the assembly of the protective rod 3 and the mounting sleeve 17.

[0031] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
