Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, and in particular to a high-toughness, pressure-resistant tactile paving strip. Background Technology

[0002] Blind people, as a special group in society, cannot rely on sight to identify directions and potential dangers when traveling, unlike sighted people. They mainly rely on hearing, touch, and assistive devices to navigate and ensure their safe arrival at their destination. Traveling is fraught with inconvenience for the blind. Tactile paving is a road facility specifically laid for the blind in urban roads and public areas. By installing tactile strips on its surface, blind people can use their canes and the tactile sensation of their feet to sense and determine their route. However, tactile paving strips wear down and break over time. Therefore, a high-toughness tactile paving strip is needed that can generate moderate elastic deformation like a spring when subjected to external impact, buffering the external force and preventing breakage. This ensures that the tactile paving provides stable and reliable guidance for the blind, improving its durability and practicality, and better serving their travel needs.

[0003] Existing tactile paving strips are made of various materials such as concrete, ceramic, plastic, and stainless steel. They use different textures to prevent slipping and provide guidance. Although they all have a certain guiding and identification function, they are prone to wear and tear and falling off during long-term use. Stainless steel tactile paving strips with anti-slip textures and installed on special roads have increased durability, but they lack toughness and are easily deformed and damaged under greater or concentrated pressure. Vibrations from passing vehicles can easily cause the installation to loosen, resulting in falling off and reduced effectiveness. Furthermore, when it rains, rainwater comes into contact with the surface of the tactile paving strips, which significantly reduces the static friction coefficient compared to normal conditions and other types of tactile paving, reducing anti-slip performance and greatly affecting the travel safety of visually impaired people, making it difficult to meet their travel needs. Utility Model Content

A limiting groove 203 is opened at the bottom of the inner wall of the connecting block 202. The connecting plate 201 is connected and fixed to the connecting block 202. The limiting groove 203 at the bottom of the inner wall of the connecting block 202 restricts the range of movement of the connecting plate 201 and prevents it from falling off after long-term use. Multiple hidden holes 204 are opened on the front and rear sides of the top of the connecting block 202. A rubber block 205 is fixedly connected to the top of the inner wall of the connecting block 202. A screw 206 is threadedly connected to the inner wall of the hidden hole 204. The hidden hole 204 is to provide additional fixing points without affecting the overall aesthetics. The screw 206 is used to fix the overall structure of the tactile paving strip. The rubber block 205 provides a squeezing effect to ensure its effectiveness and durability in actual application.

[0033] Please see the appendix Figure 1 and attached Figure 4 The top center of the top plate 7 has a nameplate slot 11. The inner wall of the nameplate slot 11 is fixedly connected to a nameplate 12, which can firmly fix a nameplate 12 to the inner wall of the nameplate slot 11, making the identification information clearer. The front top of the sealing strip 6 is fixedly connected to a reflective strip 13, and the rear top of the reflective strip 13 is fixedly connected to a reflective strip 2 14.

The inner wall of the sealing strip 6 is fixedly connected to the outer wall of the top plate 7, and multiple human-shaped strips 9 are arranged symmetrically from left to right.

[0034] Please see the appendix Figure 1 and attached Figure 5 A decorative strip 15 is fixedly connected to the top left side of the right connecting block 202, and a decorative strip 26 is fixedly connected to the top right side of the right connecting block 202. The decorative strips 15 and 26 provide aesthetics and also play an auxiliary anti-slip role. A mating piece 17 is fixedly connected to the rear top of the right connecting block 202, and a mating groove 18 is opened on the front top of the right connecting block 202. The screw 206 is threadedly connected to the inner wall of the rubber block 205 and the connecting plate 201. The mating piece 17 is connected to other connecting blocks 202 through the mating groove 18. The modular structure facilitates maintenance. The screw 206 is threadedly connected to the inner wall of the rubber block 205 and the connecting plate 201, ensuring the stability of the structure. The bottom of the connecting plate 201 is engaged with the inner wall of the limiting groove 203.

[0035] Working principle: The base plate 1 provides bottom support for the structure. A rubber pad 3 is fixedly connected to the top of the base plate 1 for initial cushioning. An installation groove 4 is opened on the top of the rubber pad 3 so that the aluminum foam 5 can be installed inside. Due to the aluminum foam 5's certain metal strength, porous foam structure, and lightweight material, it has excellent energy absorption and cushioning capabilities. The top plate 7 is installed on top of the aluminum foam 5 and is fixedly connected to the top of the rubber pad 3 by the sealing strip 6 to form a sealing structure. The aluminum foam 5 and the rubber pad 3 work together to enable the tactile paving strip to better cope with the impact of large and concentrated pressure, effectively protecting its structural integrity and installation firmness. A guide slope 8 is opened on the top of the top plate 7, and human-shaped strips 9 are evenly set on the top to provide anti-slip performance. Anti-slip grooves 10 are also evenly opened on the top of the human-shaped strips 9 to further enhance anti-slip performance. When it rains, the guide slope 8 and human-shaped strips 9 prevent water accumulation and increase friction to ensure travel safety and meet the needs of people.

[0036] When installing tactile paving strips, the connecting block 202 is fixedly connected to the accurate position on the special road. Since the connecting plates 201 are fixedly connected to both ends of the base plate 1, the connecting plates 201 can be slidably installed into the connecting block 202. During the installation and sliding process, the rubber block 205 set on the top of the inner wall of the connecting block 202 provides extrusion force. When sliding to the designated position, stop sliding and release to lock the connecting plate 201 into the limiting groove 203, effectively preventing loosening and falling off after long-term use. At this time, tighten the screw 206 to make it enter the hidden hole 204 and hide and tighten it to complete the fixing of the tactile paving strip. When it is accidentally damaged and needs to be disassembled and replaced, simply unscrew the screw 206 and pull the tactile paving strip upward to slide it out. This structure allows for quick installation and replacement, prevents loss after falling off, and allows for material recycling and reuse, meeting the usage requirements.
