Description

Technical Field

[0001] This utility model relates to the field of building technology, and more specifically, it relates to a buffer-type anti-collision staircase. Background Technology

[0002] A component in a building that serves as a vertical transportation link between floors, used for traffic connections between floors and when there are significant differences in elevation.

[0003] Modern buildings are mostly multi-story buildings. Although high-rise buildings use elevators as the main means of vertical transportation, staircases are still required for escape in case of fire. However, some existing traditional staircases still have some inconveniences when in use. One of them is that pedestrians may fall on the stairs due to distraction or slipping. Because the staircases are uneven and sloping, people who fall on the stairs usually suffer bruises, making the injuries more serious than those caused by falls on flat ground. Therefore, a new structure is needed to solve the problem of serious injuries caused by falls on existing staircases.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a buffer-type anti-collision staircase.

[0012] The present invention is further configured such that: the top side of the anti-slip strip near the step tread is provided with a first rounded corner, and the top side of the rigid pedal near the step tread is provided with a second rounded corner.

[0013] The present invention is further configured such that: a second elastic deformation layer is fixedly connected to the kick surface of the step, the length of the second elastic deformation layer is the same as the length of the step, the bottom surface of the second elastic deformation layer abuts against the top surface of the rigid tread, and the top surface of the second elastic deformation layer is flush with the top surface of the first elastic deformation layer.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This cushioned, anti-collision staircase, such as Figure 1 , Figure 2 and Figure 4 As shown, the staircase includes a stair body 1 and several steps 2 fixedly connected to it. The tread of each step 2 is provided with an elastic buffer that covers the tread and can be elastically deformed vertically. On the side of the elastic buffer near the riser, there is an anti-slip component 3 that can slide vertically and protrude from the top surface of the elastic buffer. The anti-slip component 3 enhances the overall anti-slip performance of the structure and reduces the chance of pedestrians slipping and falling. When a pedestrian falls, the elastic buffer exerts a force on it, which in turn pushes the elastic buffer to deform elastically. The elastic force generated by the elastically deformed buffer provides stable cushioning for the falling pedestrian, reduces the degree of impact during the fall, and provides stable protection for pedestrians.

[0023] like Figures 2-4 As shown, the elastic buffer includes a first elastic deformation layer 4 fixedly connected to the tread surface of the step 2 and a rigid pedal 5 fixedly connected to the top surface of the first elastic deformation layer 4. The first elastic deformation layer 4 is fixed to the tread surface of the step 2 by adhesive bonding, and the rigid pedal 5 is fixed to the first elastic deformation layer 4 by adhesive bonding. The first elastic deformation layer 4 is made of neoprene rubber. Utilizing the good elastic deformation performance, good flame retardancy, and good weather resistance of this type of material, the first elastic deformation layer 4 has good and stable elastic deformation performance, weather resistance, and flame retardancy. When a pedestrian falls, pressure is applied to the rigid pedal 5. Under this pressure, the first elastic deformation layer 4 is squeezed and undergoes elastic deformation. The elastic force generated by the elastic deformation of the first elastic deformation layer 4 cushions the falling pedestrian, reduces the degree of impact suffered by the falling pedestrian, and achieves stable protection for the falling pedestrian.

[0024] like Figures 2-4As shown, a row of rigid guide rods 6, arranged in an array along the length of the rigid pedal 5, is fixedly connected to the bottom of the rigid pedal 5 by welding. Several rigid guide rods 6 in the same row are located in the middle section of the width of the rigid pedal 5. Guide holes 7 are provided on the tread surface of the step 2 for the rigid guide rods 6 to pass through and slide. The distance between the rigid guide rod 6 and the bottom surface of the guide hole 7 is greater than zero. The guide holes 7 serve two purposes: firstly, to provide clearance for the sliding process of the rigid guide rods 6, and thus to provide clearance for the rigid pedal 5 to slide vertically downwards. This allows the rigid pedal 5 to slide vertically downwards under pressure and compress the first elastic deformation layer 4 to undergo elastic deformation, thus ensuring the stable buffering and protective function of the first elastic deformation layer 4. Secondly, it serves to facilitate the sliding process of the rigid guide rods 6. The stable limiting mechanism allows the rigid pedal 5 to slide more stably vertically when subjected to pressure, making the deformation process of the rigid pedal 5 pressing the first elastic deformation layer 4 more stable. An elastic deformation block 8 is provided between the inner bottom surface of the guide hole 7 and the bottom surface of the rigid guide rod 6. The elastic deformation block 8 is made of neoprene rubber. Utilizing the good elastic deformation performance, good flame retardancy and good weather resistance of this type of material, it is ensured that the elastic deformation block 8 has good and stable elastic deformation performance, weather resistance and flame retardancy. As the rigid guide rod 6 slides downward, it will also compress the elastic deformation block 8 to undergo elastic deformation. In turn, the elastic force generated by the elastic deformation of the elastic deformation block 8 will further buffer the sliding process of the rigid guide rod 6, making the overall buffering effect of the structure better.

[0025] like Figures 2-4 As shown, the first elastic deformation layer 4 is configured as a rubber screen plate and has a through hole 9 for the rigid guide rod 6 to pass through the first elastic deformation layer 4. The through hole 9 is used to provide stable clearance for the rigid guide rod 6 to pass through the first elastic deformation layer 4, so that the rigid guide rod 6 can stably enter the guide hole 7. The surface of the rubber screen plate is evenly distributed with several through holes. The through holes penetrate along the thickness direction of the first elastic deformation layer 4. The through holes weaken the overall structural strength of the first elastic deformation layer 4, so that the first elastic deformation layer 4 can better deform elastically when subjected to external force. When a pedestrian falls, the force applied to the rigid pedal 5 will be transmitted to the first elastic deformation layer 4, which will compress the first elastic deformation layer 4 to deform elastically. The elastic force generated by the elastic deformation of the first elastic deformation layer 4 can stabilize and buffer the pedestrian's fall, thus protecting the fallen pedestrian.

[0026] like Figures 2-4As shown, the bottom of the rigid pedal 5 is provided with a clearance groove 10 for the anti-slip component 3 to pass through and slide. Several through-holes 11 are provided through the inner top surface of the clearance groove 10. Several anti-slip strips 12, which extend from the through-holes 11 and exit the rigid pedal 5, are fixedly connected to the top of the anti-slip component 3 by welding. The clearance groove 10 is used to stably insert the anti-slip component 3, and the sidewall of the anti-slip component 3 abuts against the groove wall of the clearance groove 10 to stably guide and limit the sliding process of the anti-slip component 3, making the sliding process of the anti-slip component 3 within the clearance groove 10 more stable and smooth. The anti-slip strips 12, by extending through the anti-slip grooves onto the rigid pedal 5, increase the surface roughness of the rigid pedal 5 at that location, thus improving the anti-slip properties. The sliding strip 12 can increase the roughness of the surface of the rigid pedal 5 near the kick surface, thereby enhancing the anti-slip performance of the rigid pedal 5 and reducing the chance of pedestrians slipping and falling. At the same time, when a pedestrian falls and accidentally presses on the anti-slip strip 12, it will exert a force on the anti-slip strip 12. Under the action of this force, the anti-slip strip 12 will slide downward. During the downward movement of the anti-slip strip 12, it will push the anti-slip component 3 downward. During the downward movement of the anti-slip component 3, it will drive the first elastic deformation layer 4 to undergo elastic deformation. With the elastic force generated by the elastic deformation of the first elastic deformation layer 4, the pedestrian's fall process is stabilized and buffered, thereby reducing the damage to the fallen pedestrian and protecting the fallen pedestrian.

[0027] like Figures 2-4 As shown, the top side of the anti-slip strip 12 near the tread of step 2 is provided with a first rounded corner 13, and the top side of the rigid pedal 5 near the tread of step 2 is provided with a second rounded corner 14. With the help of the first rounded corner 13 and the second rounded corner 14, the edges of the anti-slip strip 12 and the rigid pedal 5 can be made smoother when they come into contact with a falling pedestrian, thereby reducing the degree of injury suffered by the pedestrian during the fall and collision, making the overall structure more friendly to the falling pedestrian, and providing stable protection for the fallen person.

[0028] like Figures 2-4As shown, a second elastic deformation layer 15 is fixedly connected to the riser surface of step 2 by adhesive. The length of the second elastic deformation layer 15 is the same as the length of step 2. The bottom surface of the second elastic deformation layer 15 abuts against the top surface of the rigid tread 5, and the top surface of the second elastic deformation layer 15 is flush with the top surface of the first elastic deformation layer 4. The second elastic deformation layer 15 is made of neoprene rubber. The good elastic deformation, weather resistance and fire resistance of this type of material are used to ensure that the second elastic deformation layer 15 has good and stable elastic deformation performance, weather resistance and fire resistance. With the second elastic deformation layer 15 on the riser surface, when a pedestrian accidentally falls and hits the riser surface, the elasticity of the second elastic deformation layer 15 can reduce the damage to the falling pedestrian, making the overall cushioning and anti-collision performance of the structure better.
