Description

Technical Field

[0001] The utility model relates to the technical field of stairs, in particular to a prefabricated stair. Background Art

[0002] Prefabricated stairs, also known as precast stairs, are a stair system pre-produced in a factory and assembled on-site. They usually consist of precast treads, load-bearing side plates, handrails, and necessary connecting parts. Prefabricated stairs are popular in the construction industry for their efficient installation process, excellent quality control, and customizability.

[0003] The published patent No. CN216446382U discloses a prefabricated stair, including: two load-bearing side plates, which are arranged opposite to each other; a plurality of precast treads, which are arranged in a stepped manner between the two load-bearing side plates and are respectively connected to the two load-bearing side plates at both ends. Each precast tread includes a tread board and a first riser board. The tread board is horizontally arranged, and the first riser board is perpendicular to the tread board and is connected to the edge of the tread board; a reserved gap is provided between two adjacent precast treads; a plurality of fillers are arranged in the reserved gap between two adjacent precast treads, and each filler is respectively connected to the first riser board and the tread board of two adjacent precast treads. Although when manufacturing the precast treads of this kind of prefabricated stair, a reserved gap is left, and after the assembly is completed, the reserved gap is filled with fillers to tightly connect adjacent precast treads together to avoid interference between adjacent precast treads during assembly. However, when the stair is used at night or in an environment with insufficient light, its visibility is relatively low, which is likely to cause users to fall or get injured, especially in places lacking sufficient lighting. In addition, existing stair safety signs or luminous devices are often fixedly installed. Once damaged or reaching the end of their service life and need to be replaced, the process is cumbersome and often requires professional tools or staff to intervene, increasing the maintenance cost and complexity. Therefore, improvements are needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems raised in the above background art.

[0005] The utility model adopts the following technical scheme: a prefabricated stair, including load-bearing side plates, a tread board is fixedly installed on the side surface of the load-bearing side plates, a riser board is fixedly installed on the bottom surface of the tread board, a card slot is opened on the surface of the riser board, a magnet is fixedly installed on the inner wall of the card slot, a fluorescent strip is arranged on the inner wall of the card slot, and an iron sheet is fixedly installed on the back surface of the fluorescent strip.

[0006] Preferably, the number of the magnets is two groups, and the two groups of magnets are symmetrically distributed on the inner wall of the card slot.

[0007] Preferably, the pedals and kick plates are arranged at equal distances on the surface of the load-bearing side plates.

[0008] Preferably, screws are inserted into the surface of the load-bearing side plates, and the pedals and kick plates are fixedly installed on the surface of the load-bearing side plates through the screws. Here, the assembly can be facilitated.

[0009] Preferably, an anti-slip mechanism is provided on the top surface of the pedal. The anti-slip mechanism includes a warning layer fixedly installed on the top surface of the pedal. A rubber layer is fixedly installed on the top surface of the warning layer, and anti-slip strips are fixedly installed on the top surface of the rubber layer. Here, the safety can be improved.

[0010] Preferably, the anti-slip strips are arranged at equal distances on the top surface of the rubber layer, and the materials of the rubber layer and the anti-slip strips are both natural rubber. Here, the anti-slip effect of the rubber layer and the anti-slip strips can be improved.

[0011] Preferably, the material of the warning layer is dyed PP plastic.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. By providing fluorescent strips on the pedals, the present utility model can emit weak light at night or in a dim environment, significantly improving the visibility of the stairs, reducing the risk of users falling or getting injured. Moreover, the fluorescent strips are equipped with a magnetic fixing mechanism, and users can easily pull and replace the fluorescent strips without using any tools, making maintenance and updating simple and fast. This not only makes the use of the stairs at night safer but also provides high convenience for users by simplifying the replacement process of the fluorescent strips, making the daily maintenance of the stairs easier. At the same time, since the fluorescent strips emit light only relying on the optical principle and do not require power supply, this design is both environmentally friendly and energy-saving.

[0014] 2. The rubber layer in the present utility model itself has a large friction force, which can significantly increase the grip of users when walking on the stairs and reduce the occurrence of slipping accidents. The additionally provided anti-slip strips further enhance the anti-slip effect of the stair treads, especially under wet and slippery conditions. When the rubber layer wears to a certain extent, the underlying red warning layer is exposed, providing an obvious replacement signal for maintenance personnel and timely reminding them to replace the anti-slip mechanism, thereby avoiding the slipping risk caused by wear. At the same time, through the design of the warning layer, it is possible to accurately determine when the anti-slip layer needs to be replaced, avoiding unnecessary costs caused by premature replacement and preventing potential safety hazards caused by late replacement. The practicability is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1

[0026] Please refer to Figures 1-6, the present utility model provides a technical solution: an assembled staircase, including a load-bearing side plate 1, on the surface of which screws 8 are inserted. The connection method fixed by the screws 8 is not only simple but also stable. For example, the screws 8 can be in the form of self-tapping screws or machine bolts, etc., to ensure a tight connection between the tread 2 and the riser 3 and the load-bearing side plate 1. The technical effect of such a connection method is convenient for installation and disassembly, while ensuring the stability and durability of the staircase structure. A tread 2 is fixedly installed on the side surface of the load-bearing side plate 1, and a riser 3 is fixedly installed on the bottom surface of the tread 2. The tread 2 and the riser 3 are arranged at equal distances on the surface of the load-bearing side plate 1, providing uniform supporting force and ensuring safety and comfort during use. A card slot 4 is opened on the surface of the riser 3, and magnets 5 are fixedly installed on the inner wall of the card slot 4. The number of magnets 5 is two groups, and the two groups of magnets 5 are symmetrically distributed on the inner wall of the card slot 4. This symmetrical layout of the magnets 5 enhances the stability of the fluorescent strip 6 in the card slot 4 and prevents it from sliding or falling off during use. A fluorescent strip 6 is arranged on the inner wall of the card slot 4, and an iron sheet 7 is fixedly installed on the back of the fluorescent strip 6. Such a design enables the fluorescent strip 6 to be firmly adsorbed in the card slot 4 by the magnet 5, and at the same time, it is convenient for users to easily replace the fluorescent strip 6 when needed.

[0027] Please refer to Figures 1-6 , during assembly, only need to place the tread 2 and the riser 3 on the load-bearing side plate 1, and then fix them through the screws 8 to complete the assembly. At the same time, through the set fluorescent strip 6, it can emit a weak light at night, which can facilitate users to walk at night and reduce potential safety hazards. After the fluorescent strip 6 reaches the end of its service life, the user only needs to pull the fluorescent strip 6 outwards, and then the fluorescent strip 6 can drive the iron sheet 7 away from the magnet 5. At this time, the fluorescent strip 6 leaves the card slot 4, and the fluorescent strip 6 is removed. Then, only need to align the new fluorescent strip 6 and put it into the card slot 4. After the iron sheet 7 abuts against the magnet 5, due to the magnetic force, the magnet 5 can attract the iron sheet 7, thereby fixing the fluorescent strip 6 in the card slot 4. The design of this fluorescent strip 6 not only facilitates users to walk at night and increases safety, but also its replacement process is simple and fast, greatly facilitating the daily maintenance of users. At the same time, since the fluorescent strip 6 only emits light based on the optical principle and does not require power supply, this design is both environmentally friendly and energy-saving.

[0028] Embodiment Two

[0029] Please refer to Figures 5-6, an anti-slip mechanism is provided on the top surface of the pedal 2. The anti-slip mechanism includes a warning layer 9. The material of the warning layer 9 is dyed PP plastic, which is not only strong and durable but also has a good warning effect. Especially when dyed in a bright color such as red, it can immediately attract attention when the pedal 2 is severely worn and the warning layer 9 is exposed. The warning layer 9 is fixedly installed on the top surface of the pedal 2, and it can be fixed by gluing or screwing. Such an assembly method is convenient for maintenance and replacement. A rubber layer 10 is fixedly installed on the top surface of the warning layer 9, and an anti-slip strip 11 is fixedly installed on the top surface of the rubber layer 10. The anti-slip strips 11 are arranged at equal distances on the top surface of the rubber layer 10. The equal-distance arrangement design enables a uniform anti-slip effect to be obtained with each step of stepping. The materials of the rubber layer 10 and the anti-slip strips 11 are both natural rubber. This material not only has good elasticity and wear resistance but also can effectively increase the friction force to prevent slipping.

[0030] Working principle: During assembly, only the pedal 2 and the kick plate 3 need to be placed on the load-bearing side plate 1, and then they can be completely assembled by fixing with screws 8. At the same time, through the set fluorescent strip 6, it can emit a faint light at night, which can facilitate users to walk at night, reduce safety hazards. After the service life of the fluorescent strip 6 expires, the user only needs to pull the fluorescent strip 6 outwards. Then the fluorescent strip 6 can drive the iron sheet 7 to leave the magnet 5. At this time, the fluorescent strip 6 leaves the card slot 4, and at this time the fluorescent strip 6 is removed. Then only need to align the new fluorescent strip 6 and put it into the card slot 4. After the iron sheet 7 abuts against the magnet 5, due to the magnetic force, the magnet 5 can attract the iron sheet 7, thus fixing the fluorescent strip 6 in the card slot 4. By setting the fluorescent strip 6 on the pedal 2, the utility model can emit a faint light at night or in a dim environment, significantly improving the visibility of the stairs and reducing the risk of users falling or getting injured. And the fluorescent strip 6 is equipped with a magnetic fixing mechanism, and the user can easily pull and replace the fluorescent strip 6 without using any tools, making maintenance and update simple and fast. This not only makes using the stairs at night safer, but also provides a high degree of convenience for users by simplifying the replacement process of the fluorescent strip 6, making the daily maintenance of the stairs easier. At the same time, since the fluorescent strip 6 only emits light relying on the optical principle and does not require power supply, this design is both environmentally friendly and energy-saving. The set rubber layer 10 has a large friction force, which can improve the safety of users when walking and prevent slipping. And through the set anti-slip strip 11, the friction force can be further improved. When the rubber layer 10 is severely worn, the underlying warning layer 9 is exposed. At this time, since the warning layer 9 is dyed PP plastic, if it is dyed red, the red layer is exposed, and at this time the staff can be reminded to replace the anti-slip mechanism to reduce safety hazards. The rubber layer 10 in the utility model itself has a large friction force, which can significantly increase the grip of users when walking on the stairs and reduce the occurrence of slipping accidents. The additionally set anti-slip strip 11 further enhances the anti-slip effect of the stair treads, especially under wet conditions. When the rubber layer 10 is worn to a certain extent, the underlying red warning layer 9 is exposed, providing an obvious replacement signal for maintenance personnel and timely reminding that the anti-slip mechanism needs to be replaced, thus avoiding the slipping risk caused by wear. At the same time, through the design of the warning layer 9, it can accurately determine when the anti-slip layer needs to be replaced, avoiding unnecessary costs caused by premature replacement and preventing increased safety hazards caused by late replacement.

[0031] The above is only a preferred embodiment of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent change equivalent embodiments and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
