Abstract
Description
Technical Field
[0001] This utility model relates to the field of road infrastructure technology, and in particular to a municipal tactile paving with raised sections that are not easily detached. Background Technology
[0002] Tactile paving refers to special paths set up on sidewalks or other areas specifically for visually impaired people. Tactile paving includes directional tactile paving and indicator tactile paving. Directional tactile paving uses raised strips of tactile paving bricks to help visually impaired people clearly perceive the direction of travel, while indicator tactile paving uses dotted tactile paving bricks and is used at intersections, bus stops, and other places where people need to stop or change direction. The installation of tactile paving provides visually impaired people with safe and convenient walking path guidance, helping them move independently in the urban environment and ensuring their travel safety and right of way.
[0003] The raised structures on tactile paving bricks are generally integrally formed with the paving brick body, and are usually made of ordinary cement or ceramic materials. The raised structures are exposed to the outdoor environment for a long time, and are prone to cracking, peeling or breaking due to wind, sun and rain erosion, temperature changes, etc. At the same time, the raised structures are also subjected to the trampling of pedestrians and the crushing of vehicles (such as electric vehicles, bicycles and even motor vehicles encroaching on the tactile paving). In particular, the raised structure part of the tactile paving brick is more likely to be worn flat or crushed, causing the raised structure to gradually fall off or be worn away from the tactile paving brick body, eventually making the raised structure less noticeable and weakening the function of the tactile paving brick. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a municipal tactile paving with raised sections that are less prone to detachment. This solves the problem that when the raised structure is made of ordinary cement or ceramic materials, the raised structure is more easily worn down or crushed, leading to the gradual detachment or wear of the raised structure from the tactile paving bricks.
[0005] To achieve the above objectives, the basic solution of this utility model is as follows: a raised, non-detachable municipal tactile paving, comprising tactile paving bricks, wherein a plurality of mounting holes are provided through the tactile paving bricks, and further comprising:
[0006] Several metal protrusions are installed on the mounting holes of the tactile paving bricks. A connecting shaft is fixedly installed on the side of the metal protrusions near the mounting holes. A socket is provided on the end of the connecting shaft away from the metal protrusions. The socket is arranged radially along the connecting shaft. A pin that can be detachably installed at the socket can abut against the tactile paving bricks.
[0007] The technical principle of this utility model is as follows: When laying tactile paving bricks, after the connecting shaft on the metal protrusion passes through the mounting hole, the insertion hole on the end of the connecting shaft is exposed on the lower surface of the tactile paving brick. At this time, a pin is inserted into the insertion hole, and the pin abuts against the lower surface of the tactile paving brick to achieve the limiting and fixing of the connecting shaft and the metal protrusion. When the tactile paving is used after installation, the metal protrusion is not easily worn or damaged, is not easily affected by severe weather or environmental conditions, and is not afraid of being run over by small non-motorized vehicles. The metal protrusion is not easily damaged or falls off. When an impact force is applied to the metal protrusion, the pin and the connecting shaft can limit the metal protrusion, making it difficult for the metal protrusion to fall off the tactile paving brick.
[0008] Furthermore, several mounting holes are evenly distributed along the upper surface of the tactile paving bricks.
[0009] With the above settings, the mounting holes can accommodate the different installation positions required by the metal protrusions, thus making the selection of the installation position of the metal protrusions more adaptable; at the same time, it makes the information indication of the tactile paving bricks more comprehensive and accurate.
[0010] Furthermore, a water-permeable groove is provided between each pair of adjacent mounting holes in the tactile paving bricks.
[0011] With the above settings, when it rains, rainwater can be quickly diverted through the drainage channels, making it less likely for excessive water to accumulate on the tactile paving. This makes the tactile paving easier to walk on, less prone to water damage, and more suitable for maintenance and daily use. The tactile paving bricks and metal protrusions are also less likely to be damaged.
[0012] Furthermore, the width of the longitudinal section of the water-passing groove is 1 to 2 centimeters, and several water-passing grooves are interconnected to form a grid.
[0013] With the above settings, the width of the drainage groove is more suitable, making it less likely for the white cane to be embedded in the speaker to obtain information. Furthermore, after several drainage grooves are interconnected to form a grid, the entire drainage groove can guide rainwater more smoothly, allowing the rainwater to flow in a more comprehensive direction, thus improving the drainage performance.
[0014] Furthermore, the metal protrusion is in the shape of a frustum or a keyway, and a ring is integrally formed on the end of the metal protrusion with a larger diameter. The ring is coaxially arranged with the metal protrusion, and an arched groove is coaxially arranged at the mounting hole of the tactile paving brick for embedding the ring.
[0015] With the above settings, depending on the different types of tactile paving, frustum-shaped or keyway-shaped metal protrusions can be installed on the tactile paving bricks to achieve different information indication functions of the tactile paving; the rings and grooves make the metal protrusions more stably installed on the tactile paving bricks.
[0016] Furthermore, the edge of the metal protrusion furthest from the mounting hole has a smooth curved surface.
[0017] With the above configuration, when force is applied to the smooth curved surface of the metal protrusion, the smooth curved surface transmits the force to the center of the metal protrusion, making the local part of the metal protrusion less susceptible to impact damage.
[0018] Furthermore, the metal protrusions have anti-slip textures on their cross-sections away from the mounting holes.
[0019] With the above-mentioned design, the anti-slip texture on the raised metal surface of the tactile paving can effectively prevent slipping, making it safer for blind people to walk. Attached Figure Description

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0025] This embodiment is basically as follows: Figure 1 , Figure 2 and Figure 3 As shown in the figure, this utility model embodiment proposes a municipal tactile paving with raised sections that are not easy to fall off, including a tactile paving brick body 10 and several metal protrusions 20. Several mounting holes 101 are provided through the tactile paving brick body 10. The mounting holes 101 are evenly arranged along the upper surface of the tactile paving brick body 10. A water-permeable groove 102 is provided between two adjacent mounting holes 101 of the tactile paving brick body 10. The width of the longitudinal section profile of the water-permeable groove 102 is 1.5 cm, and the several water-permeable grooves 102 are interconnected to form a vertically intersecting grid. The horizontal distance between a single water-permeable groove 102 and an adjacent mounting hole 101 is consistent.
[0026] like Figure 1 As shown, the metal protrusion 20 is installed on the mounting hole 101 of the tactile paving brick 10. A connecting shaft 201 is integrally formed on the side of the metal protrusion 20 near the mounting hole 101. The connecting shaft 201 passes through the mounting hole 101, and an insertion hole 202 is provided on the end of the connecting shaft 201 away from the metal protrusion 20. Figure 2 and Figure 3 As shown, the insertion hole 202 is arranged radially along the connecting shaft 201. A pin 203 that can abut against the tactile paving brick 10 is detachably installed at the insertion hole 202. Nuts 213 that can abut against the side wall of the connecting shaft 201 are provided at both ends of the pin 203.
[0027] At the same time, such as Figure 1 As shown, the metal protrusion 20 is in the shape of a frustum or a keyway, and a ring 205 is integrally formed on the end of the metal protrusion 20 with a larger diameter. The ring 205 is coaxially arranged with the metal protrusion 20. A groove for embedding the arched ring 205 is coaxially arranged at the mounting hole 101 of the tactile paving brick body 10. The edge of the end of the metal protrusion 20 away from the mounting hole 101 is a smooth curved surface. Anti-slip texture 204 is provided on the cross-section of the metal protrusion 20 away from the mounting hole 101.
[0028] In addition, the metal protrusion 20, the connecting shaft 201 and the pin 203 are all made of stainless steel, and the upper surface of each tactile paving brick 10 is square.
[0029] In this embodiment, a type of municipal tactile paving with raised sections that are not easily detached is used. When the tactile paving brick 10 is installed on the pedestrian walkway, several metal protrusions 20 are first installed on the tactile paving brick 10. After the connecting shaft 201 on the metal protrusion 20 passes through the mounting hole 101, the insertion hole 202 on the end of the connecting shaft 201 is exposed on the lower surface of the tactile paving brick 10. At this time, a pin 203 is inserted into the insertion hole 202, and a nut 213 is installed on the pin 203. The pin 203 abuts against the lower surface of the tactile paving brick 10 to limit and fix the connecting shaft 201 and the metal protrusion 20. During this process, depending on the different types of tactile paving, frustum-shaped metal protrusions 20 or keyway-shaped metal protrusions 20 can be installed on the tactile paving brick 10 to achieve different information indication functions of the tactile paving.
[0030] After installing the metal protrusions 20, ensure that the pins 203 on the tactile paving bricks 10 are all facing downwards, and then use an adhesive such as concrete to lay the tactile paving bricks 10 on the road.
[0031] When the tactile paving is in use, the blind person's cane can strike the metal protrusion 20 to obtain the directional information. At the same time, the anti-slip texture 204 on the top surface of the metal protrusion 20 can effectively prevent slipping. The metal protrusion 20 is not easily worn or damaged, nor is it affected by severe weather or environmental conditions. It is also not afraid of being run over by small non-motorized vehicles. The metal protrusion 20 is not easily damaged or detached. When an impact force is applied to the metal protrusion 20, the pin 203 and the connecting shaft 201 can limit the metal protrusion 20, making it difficult for the metal protrusion 20 to fall off the tactile paving brick 10.
[0032] When encountering severe weather such as rain and snow, the stainless steel metal protrusions 20 also have good environmental adaptability and are not easily damaged or detached.
[0033] When it rains, rainwater can be quickly diverted through the drainage channels, making it less likely for excessive water to accumulate on the tactile paving. This makes the tactile paving easier to walk on and less prone to water damage, making the maintenance and daily environment of the tactile paving more suitable. The tactile paving bricks 10 and metal protrusions 20 are also less likely to be damaged.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
