Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a prefabricated concrete curbstone quick installation structure for road construction. Background Technology

[0002] In road construction, concrete curb stones are crucial structures used to define road boundaries, protect road edges, and enhance road aesthetics. Traditional curb stone installation typically employs on-site casting or precast component laying, with precast component laying being widely used due to its higher construction efficiency. However, existing prefabricated concrete curb stone installation methods still have certain limitations. For example, during construction, the connection between curb stones often relies on mortar filling or mechanical fixing, which not only increases construction steps and time costs but also places higher demands on construction precision. Furthermore, some existing installation structures are not adequately designed to accommodate rapid disassembly and reuse, leading to significant manpower and material costs during later maintenance or replacement. Therefore, we propose a rapid installation structure for prefabricated concrete curb stones in road construction to optimize the installation process and improve construction efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated concrete curbstone quick-installation structure for road construction, which solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a prefabricated concrete curbstone quick installation structure for road construction includes a base component, a connecting component, and a locking component. The base component enables rapid positioning of the curbstone, the connecting component enables precise docking between adjacent curbstones, and the locking component enables stable fixing of the curbstone.

[0005] The base assembly includes a base plate and positioning grooves. The base plate is a rectangular flat plate with multiple positioning grooves evenly distributed along its length. Each positioning groove has a trapezoidal cross-section, with an opening wider than its bottom to accommodate the protruding bottom portion of the curbstone. Extension plates are installed on both sides of the base plate, welded perpendicularly to it. Threaded holes are provided on the outer sides of the extension plates for connection to ground fixing devices. An anti-slip pad made of rubber is installed on the bottom of the base plate and is adhesively fixed to its lower surface.

[0006] The connecting assembly includes connectors and guides. The connectors, cylindrical in shape, are located at both ends of the curbstone. Their outer surface features spiral protrusions to enhance the bond strength with the curbstone's interior. One end of the connector is embedded in the curbstone and secured with high-strength adhesive, while the other end extends beyond the curbstone and has a groove. The guides are U-shaped, with grooves on their inner side that match the spiral protrusions on the connector's outer surface. Both ends of the guides are engaged and secured with the connectors of adjacent curbstones. Reinforcing ribs, evenly distributed along the guide's length, are located on the outer side of the guide to improve its overall strength.

[0007] The locking assembly includes a locking rod and a locking sleeve. The locking rod is cylindrical with a tapered head at one end and an external thread at the other. The tapered head of the locking rod inserts into a slot in the connector. By rotating the locking rod, it moves along the slot, thus achieving a tight connection between the connector and the guide. The locking sleeve is cylindrical with an internal thread on its inner surface that matches the external thread of the locking rod. The locking sleeve is fitted over the locking rod and secured by a threaded connection. The outer surface of the locking sleeve has anti-slip textures for easy manual rotation.

[0008] The base assembly, connecting assembly, and locking assembly work together as follows: The bottom protrusion of the curbstone is inserted into the positioning groove of the base plate; the trapezoidal design of the positioning groove enables rapid positioning of the curbstone. The connectors of adjacent curbstones are inserted into both ends of the guide member; precise alignment is achieved through the engagement of the groove on the inner side of the guide member and the spiral protrusion on the outer surface of the connector. The conical head of the locking rod is inserted into the slot of the connector, and the locking rod is rotated to move along the slot until the connector and guide member are tightly connected. Finally, the locking sleeve is fitted over the locking rod and secured with a threaded connection, completing the stable installation of the curbstone.

[0009] The extension plate of the base plate is bolted to the ground fixing device. The bolts pass through threaded holes on the outside of the extension plate and are secured with pre-embedded nuts in the ground. The anti-slip pad is 5mm thick and has anti-slip textures on its surface to increase friction between the base plate and the ground. The connector is 10cm long, with spiral protrusions on its outer surface 2mm high and 5mm spaced to enhance its bonding strength with the curbstone. The guide is 15cm long, with an inner groove 3mm deep and 4mm wide for precise engagement with the spiral protrusions on the connector's outer surface. The locking rod is 12cm long, with a conical head diameter of 8mm and a cone angle of 30° for easy insertion into the connector's slot. The locking sleeve is 6cm long, with an internal thread pitch of 2mm for precise engagement with the locking rod's external thread.

[0010] This invention achieves rapid positioning of curb stones through a base assembly, precise alignment between adjacent curb stones through a connecting assembly, and stable fixing of curb stones through a locking assembly. It effectively solves the problems of cumbersome construction steps, high precision requirements, and difficult maintenance in existing technologies. The positioning groove design of the base assembly simplifies the curb stone installation process, the plug-in and guide designs of the connecting assembly improve the connection accuracy between curb stones, and the locking rod and locking sleeve designs of the locking assembly enhance the fixing effect of the curb stones. Furthermore, the design of anti-slip pads and reinforcing ribs further improves the stability and durability of the overall structure, making this installation structure highly practical and promising for widespread application.

[0014] This utility model provides a prefabricated concrete curbstone quick-installation structure for road construction, the specific implementation of which is as follows (in conjunction with the attached diagram). Figures 1 to 2 The accompanying drawings, labeled 1 to 9, provide a detailed description. In actual construction, this installation structure, through the coordinated operation of the base assembly, connecting assembly, and locking assembly, achieves rapid positioning, precise alignment, and secure fixing of the curbstone, thereby significantly improving construction efficiency and reducing maintenance costs.

[0015] like Figure 1 As shown, the overall structure includes a base assembly, a connecting assembly, and a locking assembly, which respectively perform the functions of positioning the curbstone, connecting adjacent curbstones, and fixing the entire structure. The base assembly consists of a base plate 1, positioning grooves 2, extension plates 3, and anti-slip pads 4. The base plate 1 is a rectangular flat plate structure with multiple positioning grooves 2 evenly distributed along its length on its upper surface. The cross-section of each positioning groove 2 is trapezoidal, with the opening width greater than the bottom width. This design facilitates the insertion of the protruding part at the bottom of the curbstone and ensures its stable embedding. Extension plates 3 are vertically welded to both sides of the base plate 1. Threaded holes are opened on the outer side of the extension plates 3 for bolt connection to the ground fixing device. A 5mm thick anti-slip pad 4 is adhered to the lower surface of the base plate 1. The anti-slip pad 4 is made of rubber material and has anti-slip textures on its surface to enhance the friction between the base plate 1 and the ground, preventing displacement during construction.

[0016] The connecting assembly consists of a connector 5 and a guide 6. The connector 5 is a cylindrical structure with spiral protrusions on its outer surface. The spiral protrusions are 2mm high and 5mm apart, which enhances the bonding strength between the connector 5 and the curbstone. One end of the connector 5 is embedded in the curbstone and fixed with high-strength adhesive, while the other end extends out of the curbstone and has a groove for subsequent engagement with the locking assembly. The guide 6 is a U-shaped structure with grooves on its inner side that match the spiral protrusions on the outer surface of the connector 5. The grooves are 3mm deep and 4mm wide. Both ends of the guide 6 are engaged and fixed with the connectors 5 of adjacent curbstones. In addition, reinforcing ribs 7 are evenly distributed along the length of the outer side of the guide 6. The design of the reinforcing ribs 7 improves the overall strength of the guide 6, enabling it to withstand greater external pressure without deformation.

[0017] The locking assembly consists of a locking rod 8 and a locking sleeve 9. The locking rod 8 is a cylindrical structure with a tapered head at one end. The tapered head has a diameter of 8mm and a taper angle of 30°. The other end has an external thread. The tapered head of the locking rod 8 is inserted into the slot of the connector 5. By rotating the locking rod 8, it moves along the slot until the connector 5 is tightly connected to the guide 6. The locking sleeve 9 is a cylindrical structure with an internal thread on its inner surface that matches the external thread of the locking rod 8. The pitch of the internal thread is 2mm. The locking sleeve 9 is fitted over the locking rod 8 and fixed by a threaded connection. The outer surface of the locking sleeve 9 has anti-slip textures to facilitate manual rotation.

[0018] In the actual construction process, the bottom protrusion of the curbstone is first inserted into the positioning groove 2 of the base plate 1. Due to the trapezoidal design of the positioning groove 2, the curbstone can be positioned quickly and accurately. Then, the connectors 5 of adjacent curbstones are inserted into both ends of the guide 6. The groove on the inner side of the guide 6 precisely matches the spiral protrusion on the outer surface of the connector 5, ensuring accurate alignment between adjacent curbstones. Next, the conical head of the locking rod 8 is inserted into the slot of the connector 5. By rotating the locking rod 8, it moves along the slot until the connector 5 and the guide 6 are tightly connected. Finally, the locking sleeve 9 is fitted onto the outside of the locking rod 8 and fixed with a threaded connection, completing the stable installation of the curbstone. During this process, the extension plate 3 is fixed with the pre-embedded nuts in the ground using bolts, further enhancing the stability of the overall structure. The anti-slip pad 4 not only improves the friction between the base plate 1 and the ground but also effectively reduces installation errors caused by uneven ground.

[0019] To verify the actual effectiveness of this installation structure, a field test was conducted in a municipal road construction project. The test section was 500 meters long, and the rapid installation structure provided by this utility model was used to assemble the curb stones. During construction, the base plate 1 was first laid in the predetermined position according to the design requirements. The extension plate 3 was connected to the ground fixing device with bolts, ensuring that the levelness of the base plate 1 met the construction specifications. Subsequently, the prefabricated curb stones were inserted one by one into the positioning groove 2 of the base plate 1. Adjacent curb stones were precisely aligned using the connector 5 and guide 6. The locking rod 8 and locking sleeve 9 operated simply and efficiently, and the installation time for a single curb stone was only one-third of that of the traditional method. The entire construction process did not require mortar filling or complex mechanical fixing equipment, significantly reducing construction steps and time costs. After testing, the overall stability of the installed curb stones was good, and the alignment accuracy between adjacent curb stones reached within 0.5mm, fully meeting the construction quality requirements.

[0020] During later maintenance, when the curb needs to be replaced or adjusted, the curb can be easily removed simply by loosening the locking sleeve 9 and taking out the locking rod 8, without damaging the original structure or repaving the base plate 1. This feature gives the installation structure a significant advantage in reusability, greatly reducing the manpower and material resources required for later maintenance. In addition, the reinforcing ribs 7 of the guide component 6 have demonstrated excellent compressive strength during long-term use. Even under frequent heavy vehicle traffic, the guide component 6 has not shown significant deformation or damage, fully demonstrating the rationality and reliability of its structural design.

[0021] As can be seen from the above specific embodiments, the prefabricated concrete curbstone quick-installation structure for road construction provided by this utility model has the following characteristics: the positioning groove 2 of the base component simplifies the curbstone installation process; the plug-in part 5 and guide part 6 of the connecting component improve the connection accuracy between curbstones; and the locking rod 8 and locking sleeve 9 of the locking component enhance the fixing effect of the curbstones. Meanwhile, the anti-slip pad 4 and reinforcing rib 7 further improve the stability and durability of the overall structure, making this installation structure highly practical and promising for widespread application.

[0022] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0023] In actual construction, the base plate 1 is first laid in the predetermined position according to the design requirements, ensuring its levelness meets the construction specifications. The extension plate 3 is connected to the ground fixing device using bolts. The threaded holes on the outer side of the extension plate 3 are secured with pre-embedded nuts in the ground, thereby enhancing the overall stability of the base plate 1. The anti-slip pad 4 further improves the friction between the base plate 1 and the ground, effectively reducing installation errors even on uneven surfaces. The positioning grooves 2 on the upper surface of the base plate 1 are evenly distributed along its length. Their trapezoidal cross-section design facilitates the insertion of the protruding part at the bottom of the curbstone, while the opening width being wider than the bottom width ensures that the curbstone can be quickly and accurately embedded into the positioning grooves 2, achieving initial positioning.

[0024] Subsequently, the prefabricated curb stones are inserted one by one into the positioning grooves 2 of the base plate 1. Adjacent curb stones are precisely aligned using connectors 5 and guides 6. One end of the connector 5 is embedded inside the curb stone and secured with high-strength adhesive, while the other end extends out of the curb stone and has a slot for subsequent engagement with the locking assembly. The guide 6 has a U-shaped structure with grooves on its inner side that match the spiral protrusions on the outer surface of the connector 5. The grooves are 3mm deep and 4mm wide, ensuring a precise fit between the connector 5 and the guide 6. Furthermore, the reinforcing ribs 7 evenly distributed along the length of the guide 6 significantly improve its overall strength, enabling it to withstand greater external pressure without deformation. Precise alignment between the curb stones is achieved by inserting the connectors 5 of adjacent curb stones into both ends of the guide 6.

[0025] Next, the tapered head of the locking rod 8 is inserted into the slot of the connector 5. The tapered head of the locking rod 8 has a diameter of 8mm and a taper angle of 30°, a design that facilitates smooth insertion into the slot. By rotating the locking rod 8, it moves along the slot until the connector 5 and guide 6 are tightly connected. The locking sleeve 9 has a cylindrical structure with an internal thread on its inner surface that matches the external thread of the locking rod 8. The pitch of the internal thread is 2mm. The locking sleeve 9 is fitted over the locking rod 8, and the threaded connection is completed by manually rotating the locking sleeve 9. This process is not only simple and efficient, but also significantly enhances the overall fixing effect of the curbstone.

[0026] The entire construction process eliminates the need for mortar filling or complex mechanical fixing equipment, significantly reducing construction steps and time costs. For example, in a municipal road construction project, the test section was 500 meters long. When using the rapid installation structure provided by this invention to assemble curb stones, the installation time for a single curb stone was only one-third of that using traditional methods. Testing showed that the installed curb stones exhibited good overall stability, with the mating accuracy between adjacent curb stones within 0.5mm, fully meeting construction quality requirements.

[0027] During later maintenance, when the curbstone needs to be replaced or adjusted, it can be easily removed by simply loosening the locking sleeve 9 and taking out the locking rod 8, without damaging the original structure or repaving the base plate 1. This feature gives the installation structure a significant advantage in reusability, greatly reducing the manpower and material resources required for later maintenance. In addition, the reinforcing ribs 7 of the guide component 6 have demonstrated excellent compressive strength during long-term use. Even under frequent heavy vehicle traffic, the guide component 6 has not shown significant deformation or damage, fully demonstrating the rationality and reliability of its structural design.

[0028] As can be seen from the above steps, this utility model achieves rapid positioning, precise alignment, and stable fixing of curb stones through the coordinated operation of the base assembly, connecting assembly, and locking assembly. The positioning groove 2 of the base assembly simplifies the installation process of the curb stones, the plug-in part 5 and guide part 6 of the connecting assembly improve the connection accuracy between curb stones, and the locking rod 8 and locking sleeve 9 of the locking assembly enhance the fixing effect of the curb stones. At the same time, the design of the anti-slip pad 4 and reinforcing rib 7 further improves the stability and durability of the overall structure, making this installation structure highly practical and promising for widespread application.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
