Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a combination device for anti-slip and anti-fall of building stairs to improve safety. Background Technology

[0002] In modern building systems, staircases, as core vertical transportation facilities connecting different floors, not only play a vital role in the efficient flow of people and goods but are also a crucial component of building safety systems. Whether in residential buildings, commercial complexes, public buildings, or industrial plants, staircase safety directly impacts the life, health, and property safety of users. With the rapid development of the construction industry and the increasing awareness of safety among the public, the requirements for staircase safety are becoming increasingly stringent. Therefore, it is necessary to design a combined anti-slip and anti-fall device for building staircases to enhance safety.

[0003] In terms of anti-slip properties, traditional staircases often use anti-slip stripes. However, these stripes are easily filled with dust and water stains, and the friction coefficient is significantly reduced when exposed to oil stains. They are unable to cope with complex environments such as dampness and oil, and cannot effectively ensure the safety of pedestrians. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Please refer to Figures 1 to 11 Example 1:

[0034] This utility model proposes a combined anti-slip and anti-fall device for building staircases to improve safety, comprising: a staircase frame 1; staircase steps 2 installed on the staircase frame 1, with grooves on the staircase steps 2, and an installation frame 21 installed in the grooves; a stop block 211 fixed at the lower end of the installation frame 21; a cover plate 22 installed on the installation frame 21 via a hinge; two horizontal strips 221 and two connecting plates 222 installed at the lower end of the cover plate 22, the two connecting plates 222 being located on the left and right sides of the horizontal strips 221 respectively; a T-shaped plate 223 connected between the horizontal strips 221 and the connecting plates 222 via a pin; the T-shaped plate 223 being installed at the lower end of the cover plate 22 via a screw; the T-shaped plate 223 being rotatable around the screw; a rectangular through groove on the cover plate 22; a plate base 23 installed in the rectangular through groove; a flexible plate 232 installed on the plate base 23; and a serrated anti-slip plate 2321 installed on the flexible plate 232.

[0035] In this embodiment, a rotatable rotating plate 225 is installed at the lower end of the cover plate 22. The rotating plate 225 is connected to a horizontal bar 221 near the front of the cover plate 22 via a pin. The cover plate 22 has a through hole, and a rotatable control rod 2251 is installed in the through hole. The upper end of the control rod 2251 has an internal hexagonal groove, and the lower end of the control rod 2251 is fixedly connected to the rotating shaft of the rotating plate 225. Pins are also installed on both horizontal bars 221 and both connecting plates 222. The locking plate 224 has a waist-shaped through groove. Its function is to rotate the control rod 2251 by using an Allen wrench, which can drive the rotating plate 225 to rotate, thereby linking the horizontal bar 221 and the connecting plate 222, so that the locking plate 224 rotates around the pin, realizing the rapid opening and closing of the cover plate 22. The waist-shaped through groove allows the locking plate 224 to be finely adjusted within a certain range, ensuring that the cover plate 22 is stable after installation and easy to disassemble, which is convenient for maintaining the components in the groove of the stair step 2 or cleaning accumulated water.

[0036] In this embodiment, a hook 231 is fixed at the lower end of the plate base 23, and a slot is provided at the rectangular through groove on the cover plate 22. The hook 231 is snapped into the slot on the cover plate 22. Its function is to achieve quick positioning and installation of the plate base 23 and the cover plate 22 by snapping the hook 231 into the slot.

[0037] In Example 2, based on Example 1, a T-shaped rail 233 is provided on the plate base 23, and a T-shaped groove is provided at the lower end of the flexible plate 232 to cooperate with the T-shaped rail 233 for installation. Its function is to realize the quick assembly of the flexible plate 232 and the plate base 23 through the sliding engagement structure of the T-shaped rail 233 and the T-shaped groove. At the same time, the engagement structure can restrict the lateral displacement of the flexible plate 232, ensuring that it maintains a stable position when subjected to stepping force, and avoiding the impact of loosening on the anti-slip effect.

[0038] In Example 3, based on Examples 1 and 2, a fixed post 3 is fixed to the stair step 2. A top rod 31 is fixed to the upper end of the fixed post 3, and a handrail 32 is welded to the upper end of the top rod 31. Two handrails 32 are provided, and three railings 33 are bolted to the fixed post 3. Handles 331 are welded to the railings 33, and movable rings 321 are movably mounted on the handrails 32. Safety rope hanging rings 322 are welded to the movable rings 321. The movable rings 321 have openings with the same width as the diameter of the top rods 31. The function of these openings is to provide a flexible plate 232 and a serrated anti-slip plate 2321 on the cover plate 22 of the stair step 2. The serrated structure increases the friction with the sole of the shoe, effectively preventing pedestrians from slipping even in wet, oily, or other slippery environments. The board 232 has a certain cushioning deformation capacity, conforms to the shape of the shoe sole, further enhances the anti-slip effect, and ensures walking safety. The fixed posts 3, top bars 31, and handrails 32 fixed on the stair steps 2 form a stable support frame. The two handrails 32, together with the three railings 33, provide multi-level protection for pedestrians and effectively prevent the body from accidentally rushing off the edge of the stairs. The handles 331 on the railings 33 are easy for pedestrians to grasp and use for leverage, helping to maintain body balance when going up and down the stairs. The movable rings 321 on the handrails 32 can slide flexibly along the opening of the diameter of the top bar 31. Together with the safety rope hanging rings 322, it is convenient for construction workers or people with special needs to quickly install safety ropes, restrict the range of movement, reduce the risk of falling from heights, and the adjustability of the movable rings 321 can adapt to different usage scenarios and personnel needs.

[0039] The working principle of this embodiment is as follows: When a pedestrian steps on the stair step 2, the flexible plate 232 on the cover plate 22 deforms under force, conforming to the contour of the shoe sole and increasing the contact area. The serrated anti-slip plate 2321 on its surface increases the friction between the anti-slip plate and the shoe sole through a dense protrusion structure, preventing slipping. When there are water or oil stains on the step surface, the grooves can temporarily store the liquid, preventing the liquid from spreading to the walking area and further reducing the risk of slipping. During the process of going up and down the stairs, pedestrians can maintain their balance by holding the handle 331 on the railing 33 and the handrails 32 on both sides. The protective structure composed of the railing 33 and the handrails 32 can effectively prevent the body from accidentally rushing off the edge of the stairs. For high-altitude workers or those with special needs, one end of the safety rope can be connected to the safety rope loop 322 on the movable ring 321, using the movable ring... 321 slides freely within a certain range along the opening of the top rod 31, while the safety rope restricts its range of motion to prevent falls from heights. When it is necessary to clean the water or debris in the groove of the stair step 2, use an Allen wrench to rotate the control rod 2251. The control rod 2251 drives the rotating plate 225 to rotate around the pin shaft. The rotating plate 225 is linked to the horizontal bar 221 and the connecting plate 222, which in turn causes the locking plate 224 to rotate around the pin shaft, unlocking the connection between the cover plate 22 and the mounting bracket 21. The cover plate 22 can then be opened for cleaning. If the flexible plate 232 or the serrated anti-slip plate 2321 is worn, simply remove the hook 231 at the lower end of the plate base 23 from the slot of the cover plate 22, and then pull out the flexible plate 232 along the T-shaped rail 233 to complete the disassembly and replacement. The maintenance operation is convenient and efficient.
