Description

Technical Field

[0001] This utility model relates to the field of non-metallic material manufacturing technology, specifically to highway shoulder inlay panels. Background Technology

[0002] In current highway and urban road construction, the shoulders are typically inlaid with cement or stone products. While these traditional products possess a certain degree of sturdiness and can meet the basic requirements of road shoulders to some extent, they have several significant drawbacks in practical application, adversely affecting road construction, maintenance, and road safety. These drawbacks are as follows: Construction is difficult: Cement or stone products are heavy, and a lot of manpower and resources are needed for transportation, installation and adjustment during construction. This not only prolongs the construction period, but also greatly increases the construction cost and reduces the overall efficiency of road construction.

[0003] Poor connection stability: The connection between traditional road shoulder inlays relies on cement sealing. However, after long-term erosion from natural environmental factors such as wind, rain, and sun exposure, the cement bonding layer is prone to aging and peeling. At the same time, over time, the ground surface will undergo natural settlement and displacement, which will further lead to unevenness between the inlays, seriously affecting the overall aesthetics of the road and potentially causing interference to passing vehicles.

[0004] Significant safety hazards: Due to the inherent characteristics of cement and stone materials, their surfaces are not very smooth, and the edges of the products often have sharp corners. When a vehicle runs over the shoulder panel due to an accident, these uneven surfaces and sharp corners can easily scratch and damage the vehicle's tires, and may even lead to serious accidents such as tire blowouts. Especially on highways, where vehicles travel at high speeds, the consequences of such safety hazards are even more serious, posing a threat to the lives and property of the vehicle and its occupants.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this utility model is to provide a road shoulder panel to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides a highway shoulder inlay plate, comprising: The panel has a rectangular parallelepiped structure with a hollow cavity inside. The narrow side of the panel has an opening that communicates with the hollow cavity, and the edges of the outer surface of the panel have rounded corners. A connecting plate is provided, wherein two adjacent panels are axially connected by the connecting plate. The connecting plate includes an end plate portion that fits against the narrow surface of the panel. The end plate portion has a flat plate structure. A snap-fit ​​portion extending along the thickness direction is formed on the side wall of the end plate portion. The snap-fit ​​portion is inserted into the hollow cavity through an opening.

[0008] Furthermore, the outer wall of the snap-fit ​​part and the inner wall of the insert are in clearance fit, and the clearance range is 0.2-0.5mm.

[0009] Furthermore, the structure of the snap-fit ​​part is adapted to the narrow surface of the panel, so that after the snap-fit ​​part is connected to the panel, it fits against the narrow surface of the slot to limit the radial displacement of the panel.

[0010] Furthermore, the panel is provided with a plurality of partitions extending along the width direction of the panel, and the partitions are spaced apart along the height direction of the inner wall of the hollow cavity of the panel, and the hollow cavity is divided by the partitions to form a plurality of independent hollow grooves.

[0011] Furthermore, a slot is formed between the uppermost partition and the top wall of the hollow cavity, and the locking part is inserted into the inside of the slot.

[0012] Furthermore, the shape of the snap-fit ​​portion is adapted to the shape of the slot.

[0013] Furthermore, the panel has an inner facade facing the road and an outer facade facing away from the road. The outer facade is a straight surface. The inner facade is divided into a lower straight section and a sloping facade that extends continuously along the length of the panel. One end of the sloping facade smoothly connects to the top of the lower straight section of the inner facade, and the other end extends to the top surface of the panel and forms a smooth transition.

[0014] Furthermore, grooves are provided at the lower part of both the inner and outer facades. The grooves are recessed into the inlay panel and extend along the length of the inlay panel, with the length of the grooves being the same as the length of the inlay panel.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention uses ultra-high molecular weight polyethylene modified material for the panel, which significantly reduces the weight compared to traditional cement and stone products. It can be handled by a single person without the need for heavy lifting. At the same time, the assembly method of fitting the end plate of the connecting plate and inserting the snap-fit ​​part into the slot eliminates the need to wait for the cement to solidify, and can quickly complete the axial connection and radial positioning of adjacent panels, greatly shortening the construction cycle and reducing construction labor and time costs.

[0016] This invention combines the weather resistance of ultra-high molecular weight polyethylene modified material with the elasticity of polyurethane connecting plate, which can resist natural environmental erosion and ground subsidence, avoiding the problems of aging and peeling of traditional cement connecting layer and cracking of panel. On the other hand, the internal partition and hollow groove support structure of panel, and the matching and fixing of vertical groove and foundation further enhance the overall damage resistance, reduce the frequency of later replacement, and reduce maintenance costs during road operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-7 This utility model provides a technical solution: a highway shoulder inlay plate, comprising, Panel 1 has a rectangular parallelepiped structure with a hollow cavity inside. Panel 1 is made of ultra-high molecular weight polyethylene modified material by extrusion molding. The narrow side of panel 1 has an opening that communicates with the hollow cavity inside. The edges of the outer surface of panel 1 have rounded corners. The connecting plate 6 is made of polyurethane material by injection molding. Two adjacent panels 1 are axially connected by the connecting plate 6. The connecting plate 6 includes an end plate portion 61 that fits into the narrow surface of the panel 1. The end plate portion 61 has a flat plate structure. A snap-fit ​​portion 62 extending along its thickness direction is formed on the side wall of the end plate portion 61. The snap-fit ​​portion 62 is inserted into the hollow cavity through the opening.

[0021] Specifically, panel 1 is designed as a rectangular hollow structure, made of ultra-high molecular weight polyethylene modified material through extrusion molding. Its narrow side has an opening that communicates with the hollow cavity, and the outer surface edges are rounded. The hollow structure reduces its own weight while ensuring the strength of the foundation. The opening provides an assembly interface for connecting panel 6, and the rounded corners eliminate sharp edges. The physical properties of ultra-high molecular weight polyethylene modified material lay the foundation for solving subsequent construction and safety issues.

[0022] The connecting plate 6 is injection molded from polyurethane material. The axial connection of adjacent panels 1 is achieved by the end plate part 61 fitting and the snap-fit ​​part 62 inserting. The end plate part 61 fits into the narrow surface of the panel 1 to complete the positioning. The snap-fit ​​part 62 is inserted into the hollow cavity of the panel 1 from the opening to form a mechanical connection structure, replacing the traditional cement sealing method.

[0023] As a technical optimization of this utility model, the outer wall of the snap-fit ​​part 62 and the inner wall of the insert 1 are in clearance fit, and the fit gap range is 0.2-0.5mm.

[0024] Specifically, the gap design is based on mechanical assembly logic: a small gap of 0.2-0.5mm can prevent the snap-fit ​​part 62 from getting stuck when inserted into the hollow cavity of the panel 1 due to excessive tightness, thus ensuring ease of assembly; and can also prevent lateral loosening after the adjacent panels 1 are connected due to excessive gap, thus ensuring the structural stability after connection.

[0025] As a technical optimization of this utility model, the structure of the snap-fit ​​part 62 is adapted to the narrow surface of the insert 1, so that after the snap-fit ​​part 62 is connected to the insert 1, it fits against the narrow surface of the slot 3 to limit the radial displacement of the insert 1.

[0026] Specifically, the shape and size of the snap-fit ​​part 62 match the narrow surface of the panel 1 and the narrow surface of the slot 3. After connection, a "face-to-face" contact structure is formed, which restricts the movement of the panel 1 in the radial direction and perpendicular to the length of the panel, and prevents adjacent panels 1 from being misaligned in the radial direction.

[0027] As a technical optimization of this utility model, the panel 1 is provided with a plurality of partitions extending along the width direction of the panel 1. The partitions are spaced apart along the height direction of the inner wall of the hollow cavity of the panel 1, and the hollow cavity is divided by the partitions to form a plurality of independent hollow grooves 5.

[0028] Specifically, the partition is equivalent to the internal support skeleton of the panel 1, which can disperse external forces and prevent the hollow structure from cracking due to local stress concentration. It can reduce weight while ensuring strength. Multiple independent hollow slots 5 can optimize the internal stress distribution of the panel 1 and provide a basic structure for the subsequent formation of the slot 3, realizing the multi-functional integration of weight reduction, strengthening and positioning.

[0029] As a technical optimization of this utility model, a slot 3 is formed between the uppermost partition and the inner top wall of the hollow cavity, and the snap-fit ​​part 62 is inserted into the inside of the slot 3.

[0030] Specifically, by cooperating with the cavity wall, a positioning space is formed inside the insert 1, and the uppermost part of the slot 3 is fixed to match the size of the latching part 62, which can guide the latching part 62 to be inserted accurately.

[0031] As a technical optimization of this utility model, the shape of the snap-fit ​​part 62 is adapted to the shape of the slot 3.

[0032] Specifically, surface contact is achieved through shape matching rather than point contact: for example, if the slot 3 is a rectangular slot, the snap-fit ​​part 62 is designed as a rectangular block. When the two are fitted together, there is no gap, which can maximize the contact area, distribute the force on the connection part, and avoid local stress concentration that could damage the snap-fit ​​part 62 or the slot 3.

[0033] As a technical optimization of this utility model, the panel 1 has an inner facade close to the road and an outer facade facing away from the road. The outer facade is a straight surface. The inner facade is divided into a lower straight section along the height direction of the panel 1 and an inclined facade 4 that extends continuously along the length direction of the panel 1. One end of the inclined facade 4 is smoothly connected to the top of the lower straight section of the inner facade, and the other end extends to the top surface of the panel 1 and forms a smooth transition.

[0034] Specifically, the smooth transition structure of the sloping facade 4 replaces the traditional right-angle facade. When a vehicle accidentally runs over the shoulder, it can guide the tire to make smooth contact, reducing impact and scratches. This is its core structural function. Since panel 1 is made entirely of ultra-high molecular weight polyethylene modified material, the sloping facade 4 can be made in colors that are significantly different from the road surface and shoulder base color, such as striking yellow or orange, through material color matching processes, such as adding specific color masterbatch before extrusion molding. This color design makes the sloping facade 4 a visual road edge marking strip, especially at night under lighting, in inclement weather such as rain or fog, or in low visibility conditions. The color contrast can clearly define the boundary between the shoulder and the driving lane, reminding drivers to correct their driving trajectory in time and avoid vehicles accidentally driving off the shoulder.

[0035] In practice, based on material properties and color matching techniques, the color design of the sloping facade 4 is implemented according to different scenarios, and strictly complies with the "Specifications for Setting Up Highway Traffic Signs and Markings" and local supplementary road safety regulations. A scene with a completely yellow sloping facade and no-parking signs: Before extrusion molding of panel 1, high weather-resistant yellow masterbatch is added to ultra-high molecular weight polyethylene raw material to ensure that the inclined vertical surface 4 presents a uniform yellow color. The all-yellow sloping facade forms a continuous shoulder boundary marking strip, clearly defining the parking area and the driving lane; reminding drivers that this is a stationary parking area, and they need to slow down before entering, so as to avoid mistakenly taking the parking area shoulder as an extension of the driving lane. A yellow and a black sloping facade, a scene of temporary parking signs: Before the panel 1 is extruded, high weather-resistant black masterbatch is added to the ultra-high molecular weight polyethylene raw material to ensure that the entire inclined surface 4 is uniformly black. Then, it is combined and assembled with the panel 1 of the yellow inclined surface 4 to form a striped structure of yellow and black continuous alternation. This area is identified as a temporary parking zone by color contrast, and drivers should exercise caution and avoid it. It also replaces traditional temporary parking signs, reducing the secondary work costs associated with installing and removing signs during construction.

[0036] As a technical optimization of this utility model, a groove 2 is provided at the lower part of both the inner and outer facades. The groove 2 is recessed into the inner side of the panel 1 and extends along the length of the panel 1. The length of the groove 2 is the same as the length of the panel 1.

[0037] Specifically, the groove 2 reduces the contact area between the panel 1 and the ground. When the ground settles, it can reduce the friction between the panel 1 and the ground, thus preventing cracking or displacement due to excessive force.

[0038] This utility model of a road shoulder inlay plate aims to solve the problems of difficult construction, poor connection stability, and prominent safety hazards of traditional cement and stone road shoulder products through innovative structural design and material selection. The specific structural analysis of each component is as follows: Panel 1 is made of ultra-high molecular weight polyethylene modified material through extrusion molding. Compared with traditional cement and stone, this material has the characteristics of being lightweight, high-strength, and wear-resistant. On the one hand, it significantly reduces the self-weight of a single panel 1, reducing the manpower and material input for handling and installation during construction, and directly solving the problem of the high construction difficulty of traditional products. On the other hand, the weather resistance of the material can avoid aging and damage after long-term use, extending the service life of the shoulder panel. Panel 1 has a rectangular structure with a hollow cavity inside. The hollow design further reduces weight, and through the structural balance between the hollow and solid parts, it ensures the overall load-bearing strength of panel 1, avoiding structural fragility due to weight reduction. Its narrow side has an opening that connects to the hollow cavity, providing an interface for subsequent assembly with connecting panel 6. The rounded corners of the outer surface eliminate the sharp corner hazards of traditional stone and cement products, preventing tires from being scraped when vehicles accidentally run over them, reducing safety risks from structural details. The connecting plate 6 is made of polyurethane material by injection molding. Polyurethane has good elasticity and toughness. Compared with the traditional cement connecting layer, it can better adapt to the stress changes caused by surface subsidence and displacement. Its structure includes an end plate part 61 that fits the narrow side of the panel 1 and a snap-fit ​​part 62 that is inserted into the hollow cavity of the panel 1. By fitting and positioning the end plate and inserting and fixing the snap-fit ​​part, the axial connection of adjacent panels 1 is realized, replacing the traditional cement sealing connection and solving the problem of poor connection stability from the perspective of connection method.

[0039] The snap-fit ​​part 62 has a clearance of 0.2-0.5mm with the inner wall of the panel 1. This clearance avoids assembly difficulties caused by excessive tightness and prevents the panel 1 from loosening after connection due to excessive clearance. At the same time, the structure of the snap-fit ​​part 62 is adapted to the narrow surface of the panel 1. After connection, it can fit against the narrow surface of the slot 3, directly restricting the radial displacement of the panel 1 and preventing adjacent panels 1 from shifting radially. This further improves the overall stability after connection and avoids the unevenness problem caused by loose connection in traditional products.

[0040] Multiple partitions are arranged inside the panel 1 along the width direction and are spaced apart along the height direction of the inner wall of the hollow cavity. These partitions divide the hollow cavity into multiple independent hollow slots 5. On the one hand, the partitions are equivalent to the internal support skeleton, which can disperse the external force borne by the panel 1, avoid local stress concentration caused by the hollow structure, and strengthen the overall structural strength of the panel 1. On the other hand, the slot 3 formed by the uppermost partition and the top wall of the hollow cavity provides a precise insertion and positioning space for the snap-fit ​​part 62. The shape of the snap-fit ​​part 62 is adapted to the slot 3, ensuring the assembly accuracy of the connecting plate 6 and the panel 1 and reducing connection problems caused by assembly deviation.

[0041] The inner facade of panel 1, near the road side, is divided into a lower straight section and a continuously extending sloping facade 4. The two ends of the sloping facade 4 are smoothly connected to the top of the lower straight section and the top surface of panel 1, respectively. This design replaces the right angle or rough facade of traditional products. When a vehicle accidentally runs over the road shoulder, the smooth sloping facade 4 can reduce the impact and scratches on the tires. At the same time, the outer facade is set as a straight surface to ensure the regularity of the outer side of the road shoulder and further reduce safety hazards.

[0042] The lower part of both the inner and outer facades of panel 1 has a groove 2 extending along its length, and the length of the groove 2 is the same as that of panel 1. The groove 2 is recessed towards the inner side of panel 1. On the one hand, it can fit and engage with the road shoulder foundation structure such as concrete base and fasteners during installation, thereby improving the connection stability between panel 1 and road shoulder foundation. On the other hand, the groove 2 can reduce the contact area between panel 1 and the ground, reduce the ground friction force on panel 1 when the ground settles, and prevent panel 1 from cracking due to excessive force.

[0043] In actual road construction, the single panel 1 is first transported to the designated position on the shoulder. Because the ultra-high molecular weight polyethylene modified material is lightweight, it can be transported by a single person, reducing the difficulty of construction. Then, the snap-fit ​​part 62 of the connecting plate 6 is inserted into the uppermost slot 3 inside the panel 1 through the opening of the narrow side of the panel 1, so that the end plate part 61 fits against the narrow side of the panel 1, completing the axial connection of adjacent panels 1. At the same time, the fit between the snap-fit ​​part 62 and the slot 3 restricts the radial displacement of the panel 1. Finally, the panel 1 is fitted and fixed to the shoulder foundation structure through the groove 2 at the bottom of the vertical surface, completing the overall installation.

[0044] In long-term use, the weather resistance of the ultra-high molecular weight polyethylene modified material can resist the erosion of the natural environment, and the elasticity of the polyurethane connecting plate 6 can adapt to the surface subsidence and displacement, avoiding the aging and peeling of the connecting layer; the rounded corners of the panel 1 and the sloping vertical surface 4 eliminate sharp corners and rough surfaces, reducing the safety risk of accidental vehicle crushing, and ultimately achieving the road shoulder use requirements of "convenient construction, stable connection, safety and durability".
