Technical Field
[0001] This application relates to the field of guardrail bracket technology, and more specifically, to a guardrail bracket for road and bridge design. Background Technology
[0002] In the construction of roads and bridges, guardrail supports play a crucial role. However, existing guardrail supports suffer from insufficient structural stability and are unable to withstand significant external impacts, such as vehicle collisions, which may lead to guardrail deformation or even damage, failing to effectively ensure driving safety. The assembly and disassembly process is cumbersome and complex, requiring substantial manpower and time costs, and subsequent maintenance and component replacement are extremely inconvenient. Furthermore, there are significant deficiencies in their coordination with surrounding facilities, resulting in insufficient adaptability. Therefore, we propose a new guardrail support design for roads and bridges. Utility Model Content
[0003] 1. Technical problems to be solved The purpose of this application is to provide a guardrail bracket for road and bridge design, which solves the technical problems mentioned in the background art. The guardrail bracket adopts a prefabricated design, with pre-embedded square tubes, J-shaped support tubes, horizontal tubes and other components connected by bolts, plugs and other methods. It is easy to install, greatly saves manpower and time costs, and is conducive to construction and later maintenance and repair. The overall structure is highly stable. The J-shaped support tubes are firmly combined with the pre-embedded square tubes, the horizontal tubes are reliably plugged in, the reinforcing bars connect the various parts, and there are arc-shaped wear-resistant pads for protection and corrugated plates for reinforcement. It can effectively resist external impact and ensure long-term stable and reliable protection. The elliptical through groove of the plug tube can be used to run cables, assist in equipment installation, and has strong expansion functions, meeting the technical effects of modern road and bridge diverse needs.
[0004] 2. Technical Solution This application provides a guardrail bracket for road and bridge design, comprising: a plurality of J-shaped support tubes, wherein the J-shaped support tubes are installed upside down and each of them has a pre-embedded square tube detachably installed at its bottom end; an arc-shaped support plate is fixedly welded to the upper end of each J-shaped support tube; horizontal tubes are fixed between the arc-shaped support plates by bolts, and adjacent horizontal tubes are connected end to end by interlocking; clamps are fitted on each J-shaped support tube; a fixing block is integrally fixed on each clamp; two through bars are installed horizontally between the fixing blocks; and corrugated plates are detachably installed between the fixing blocks for limiting their movement.
[0005] By adopting the above technical solution, the J-shaped support tubes are installed upside down, and the bottom ends can be detachably installed with pre-embedded square tubes. This design allows the J-shaped support tubes to stand stably on the ground foundation, providing reliable support for the entire support structure. The upper end of the J-shaped support tube is fixedly welded with an arc-shaped support plate to support the horizontal tubes. The arc structure of the J-shaped support tube helps to disperse pressure and effectively resist external impacts. The ends of the horizontal tubes are interlocked to further enhance the overall continuity and strength. The J-shaped support tubes are equipped with clamps, and the clamps are fixed with fixing blocks. Two through rods are installed horizontally between the fixing blocks, which plays a role in horizontally connecting and fixing the various parts, enhancing the lateral stability of the overall structure. Corrugated plates are detachably installed between the fixing blocks for limiting. The corrugated plates not only increase the aesthetics of the guardrail, but also play a certain role in buffering and protection. They can also be disassembled, replaced, or adjusted according to actual needs.
[0006] Optionally, a square plate is fixed to the bottom end of the J-shaped support tube, and square plates are fixed to both ends of the pre-embedded square tube. Four bolts are threadedly connected between the square plate and the square plate at the upper end of the pre-embedded square tube, and four anchor bolts are threaded through the square plate at the lower end of the pre-embedded square tube.
[0007] By adopting the above technical solution, the square plate provides a larger contact area for the connection between the J-shaped support tube and the pre-embedded square tube, which is conducive to the transmission and dispersion of force. Multiple bolts ensure a firm and reliable connection between the J-shaped support tube and the pre-embedded square tube, preventing loosening. Anchor bolts firmly fix the pre-embedded square tube to the ground foundation, providing a solid bottom support for the entire guardrail bracket. Combined with the arc-shaped structure at the upper end of the J-shaped support tube, it can resist external forces from all directions, such as the impact of vehicle collisions. The overall guardrail bracket, through its convenient prefabricated structure, significantly reduces labor and time costs, greatly improves the convenience of construction operations, and has high overall structural stability, effectively resisting various external forces and ensuring the long-term stability and reliability of the guardrail.
[0008] Optionally, both ends of the arc-shaped support plate are provided with an elliptical through groove, and two arc-shaped wear-resistant pads are welded to the inner wall of the arc-shaped support plate. Both ends of the horizontal tube are provided with through holes, and the arc-shaped support plate and the horizontal tube are fixed together by bolts through the through holes and the elliptical through groove.
[0009] By adopting the above technical solution, the design of the elliptical through grooves at both ends of the arc-shaped support plate facilitates the installation and positioning of the horizontal tubes, while also allowing for a certain amount of fine-tuning space, thus improving the flexibility and accuracy of installation. The two horizontal tubes are connected end to end by plugging, and the plugging connection is located at the arc-shaped support plate. The horizontal tubes and the arc-shaped support plate are fixed and positioned by bolts. The presence of the arc-shaped wear-resistant pad can reduce friction and wear between the horizontal tubes and the arc-shaped support plate, extend the service life of both, and play a certain role in buffering and shock absorption when subjected to vibration or impact, protecting the stability of the connection between the horizontal tubes and the arc-shaped support plate.
[0010] Optionally, one end of each horizontal tube is fixed with a connector, and each connector has an elliptical through groove for communicating with a J-shaped support tube. Two adjacent horizontal tubes are connected by inserting the connector.
[0011] By adopting the above technical solution, each end of the horizontal tube is fixed with a plug pipe, which provides a convenient plug-in method for connecting adjacent horizontal tubes, making the splicing of horizontal tubes faster and more efficient, and facilitating the disassembly, replacement or repair of horizontal tubes in the later stage, reducing maintenance costs and difficulties. The existence of the elliptical through groove II allows the horizontal tube to be connected to the J-shaped support tube, allowing cables to be threaded through the tube and assisting in the installation of lighting equipment, etc., enhancing the versatility and flexibility of the entire horizontal tube system.
[0012] Optionally, a rubber sleeve is provided inside the clamp, and multiple bolts are threaded onto the clamp for locking the clamp to the outside of the J-shaped support tube.
[0013] By adopting the above technical solution, a rubber sleeve is set inside the clamp, which has good elasticity and wear resistance. It can fit tightly against the surface of the J-shaped support tube, increase the friction between the clamp and the J-shaped support tube, prevent the clamp from sliding or loosening during use, and at the same time play a certain buffering and protection role to avoid the clamp from damaging the J-shaped support tube.
[0014] Optionally, each of the fixing blocks has two angular grooves for embedding and installing corrugated plates. Each angular groove has a positioning hole, and each fixing block has a horizontal hole corresponding to the angular groove. The horizontal hole is connected to the corresponding positioning hole, and the fixing block is installed through the horizontal hole.
[0015] By adopting the above technical solution, two angular grooves are opened on each fixing block for embedding and installing corrugated plates, which can make the corrugated plates more stable and less prone to shaking or falling out, ensuring the reliability of the connection between the corrugated plates and the fixing blocks. The design of the connection between the horizontal holes and the positioning holes allows the through-ribs to pass smoothly through the fixing blocks and be effectively connected and fixed to the corrugated plates at the positioning holes. This realizes the coordinated work between the through-ribs, the fixing blocks and the corrugated plates, enhances the structural strength and stability of the entire guardrail bracket in this local area, and greatly improves the guardrail bracket's resistance to deformation in the horizontal direction.
[0016] Optionally, the corrugated plate has through holes at each positioning hole of the fixing block for threaded installation of bolt four, and the bolt four is tightened against the through rib.
[0017] By adopting the above technical solution, the presence of through holes facilitates the installation and fixing of bolt four, enabling the corrugated plate to establish a firm connection with the through-rib through bolt four. By tightening bolt four, it can be firmly pressed onto the through-rib, further enhancing the friction and connection strength between the corrugated plate and the through-rib. This ensures that the corrugated plate and the through-rib will not undergo relative displacement or separation when subjected to external forces, thereby guaranteeing the stability and safety of the entire guardrail support structure and effectively leveraging the protective and decorative functions of the corrugated plate in the guardrail.
[0018] 3. Beneficial effects One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. The ground foundation is pre-embedded using anchor bolts for pre-embedded square tubes. J-shaped support tubes are installed upside down on the upper end of the pre-embedded square tubes. Multiple plug-in assembled horizontal tubes are then fixed at the joints using arc-shaped brackets and bolts. Clamps are installed on the outside of the J-shaped support tubes. The through-bars and corrugated plates installed between the fixing blocks on the clamps form a convenient prefabricated structure, which greatly reduces labor and time costs and significantly improves the convenience of construction operations. Whether it is the initial construction or the later maintenance and repair, the work can be carried out more quickly and efficiently. Moreover, the overall structure has high stability and can effectively resist various external forces, ensuring the long-term stability and reliability of the guardrail. 2. The design of the elliptical through groove on the plug tube connecting to the J-shaped support tube facilitates the threading of cables inside the tube and can assist in the installation of other equipment, such as lighting fixtures and monitoring equipment. This enhances the collaborative working ability and functional diversity of the guardrail bracket in the comprehensive road and bridge facilities, and better meets the development needs of modern road and bridge intelligence and multi-functionality.

The upside-down installation of the J-shaped support tubes 1 and the detachable installation of the pre-embedded square tubes 2 at their bottom ends allow the J-shaped support tubes 1 to stand stably on the ground foundation, providing a stable support for the entire bracket. Providing reliable support, the upper end of the J-shaped support tube 1 is fixedly welded with an arc-shaped support plate 3, which can be used to support the horizontal tube 4. The arc structure of the J-shaped support tube 1 helps to disperse pressure and effectively resist external impact. The ends of the horizontal tubes 4 are connected by interlocking, which further enhances the overall continuity and strength. The J-shaped support tube 1 is equipped with a clamp 5, and a fixing block 52 is fixed on the clamp 5. Two through rods 6 are installed horizontally between the fixing blocks 52, which play a role in horizontally connecting and fixing the various parts, enhancing the lateral stability of the overall structure. Corrugated plates 7 are detachably installed between the fixing blocks 52. The corrugated plates 7 not only increase the aesthetics of the guardrail, but also play a certain role in buffering and protection. They can be disassembled, replaced or adjusted according to actual needs.
[0021] Reference Figure 1 and Figure 2 A square plate 11 is fixed to the bottom of the J-shaped support tube 1, and square plates 21 are fixed to both ends of the embedded square tube 2. Four bolts 12 are threadedly connected between square plate 11 and the upper square plate 21 of the embedded square tube 2. Four anchor bolts 22 are threaded through the lower square plate 21 of the embedded square tube 2. Square plate 11 provides a larger contact area for the connection between the J-shaped support tube 1 and the embedded square tube 2, which is beneficial for force transmission and dispersion. Furthermore, the multiple bolt connections ensure a firm and reliable connection between the J-shaped support tube 1 and the embedded square tube 2. The pre-embedded square tube 2 is firmly fixed to the ground foundation using anchor bolts 22, thus providing a solid bottom support for the entire guardrail bracket. Combined with the arc structure at the upper end of the J-shaped support tube 1, it can resist external forces from all directions, such as the impact force during vehicle collisions. The overall guardrail bracket, through its convenient assembly structure, significantly reduces labor and time costs, greatly improves the convenience of construction operations, and has high overall structural stability, effectively resisting various external forces and ensuring the long-term stability and reliability of the guardrail.

Two arc-shaped wear-resistant pads 32 are welded to the inner wall of the arc-shaped support plate 3. Both ends of the horizontal tube 4 are provided with through holes 41. The arc-shaped support plate 3 and the horizontal tube 4 are fixed together by bolts 33 through the through holes 41 and the elliptical through grooves 31. The design of the elliptical through grooves 31 at both ends of the arc-shaped support plate 3 facilitates the installation and positioning of the horizontal tube 4, and also allows for a certain amount of fine adjustment space, which improves the flexibility and accuracy of installation. The two horizontal tubes 4 are connected end to end by insertion, and the insertion connection is located at the arc-shaped support plate 3. The horizontal tube 4 and the arc-shaped support plate 3 are fixed and positioned by bolts 33. The presence of the arc-shaped wear-resistant pads 32 can reduce the friction and wear between the horizontal tube 4 and the arc-shaped support plate 3, extend the service life of both, and play a certain role in buffering and shock absorption when subjected to vibration or impact, protecting the stability of the connection between the horizontal tube 4 and the arc-shaped support plate 3.
[0023] Reference Figure 1 and Figure 5 Each horizontal tube 4 has a plug tube 42 fixed at one end. Each plug tube 42 has an elliptical through groove 421 for connecting with the J-shaped support tube 1. Adjacent horizontal tubes 4 are connected by plugging in the plug tube 42. The plug tube 42 fixed at one end of each horizontal tube 4 provides a convenient plugging method for connecting adjacent horizontal tubes 4, making the splicing of horizontal tubes 4 faster and more efficient. It also facilitates the disassembly, replacement or repair of horizontal tubes 4 in the future, reducing maintenance costs and difficulty. The presence of the elliptical through groove 421 allows the horizontal tube 4 to connect with the J-shaped support tube 1, allowing cables to be threaded through the tube and assisting in the installation of lighting equipment, etc., enhancing the versatility and flexibility of the entire horizontal tube 4 system.
[0024] Reference Figure 2 and Figure 3 The clamp 5 has a rubber sleeve 51 inside, and multiple bolts 53 are threaded on the clamp 5 to lock the clamp 5 to the outside of the J-shaped support tube 1. The rubber sleeve 51 inside the clamp 5 has good elasticity and wear resistance. It can fit tightly against the surface of the J-shaped support tube 1, increase the friction between the clamp 5 and the J-shaped support tube 1, prevent the clamp 5 from sliding or loosening during use, and also play a certain role in buffering and protection to avoid the clamp 5 from damaging the J-shaped support tube 1.
[0025] Reference Figure 2 and Figure 3Each fixing block 52 has two angular slots 521 for embedding and installing the corrugated plate 7. Each angular slot 521 has a positioning hole 522. Each fixing block 52 has a horizontal hole 523 corresponding to the angular slot 521, and the horizontal hole 523 is connected to the corresponding positioning hole 522. The fixing block 52 is installed through the horizontal hole 523 to install the through rod 6. The two angular slots 521 on the fixing block 52 are used to embed and install the corrugated plate 7, which can make the corrugated plate 7 more stable and less prone to shaking or falling out, ensuring the reliability of the connection between the corrugated plate 7 and the fixing block 52. The design of the connection between the horizontal hole 523 and the positioning hole 522 allows the through rod 6 to pass smoothly through the fixing block 52 and be effectively connected and fixed to the corrugated plate 7 at the positioning hole 522. This realizes the coordinated work between the through rod 6, the fixing block 52 and the corrugated plate 7, enhances the structural strength and stability of the entire guardrail bracket in this local area, and greatly improves the guardrail bracket's resistance to deformation in the horizontal direction.
[0026] Reference Figure 1 and Figure 2 Each positioning hole 522 of the corrugated plate 7 is provided with a through hole 71 for threaded installation of bolts 72. The bolts 72 are set to abut against the through rib 6. The presence of the through holes 71 facilitates the installation and fixing of the bolts 72, so that the corrugated plate 7 and the through rib 6 can establish a firm connection through the bolts 72. By tightening the bolts 72, they can be pressed tightly against the through rib 6, further enhancing the friction and connection strength between the corrugated plate 7 and the through rib 6. This ensures that the corrugated plate 7 and the through rib 6 will not undergo relative displacement or separation when subjected to external forces, thereby ensuring the stability and safety of the entire guardrail support structure and effectively playing the protective and decorative role of the corrugated plate 7 in the guardrail.
[0027] Working principle: The pre-embedded square tube 2 is fixed to the ground foundation with anchor bolts 22. The J-shaped support tube 1 is connected to the square plate 21 on the pre-embedded square tube 2 via square plate 11 and bolt 12 to achieve inverted installation. The upper end of the J-shaped support tube 1 is fixedly welded with an arc-shaped support plate 3 for installing horizontal tubes 4. The through holes 41 at both ends of the horizontal tube 4 are aligned with the elliptical through grooves 31 on the arc-shaped support plate 3, and bolts 33 are installed and tightened to complete the assembly of the arc-shaped support plate 3 and the horizontal tube 4. Each arc-shaped support plate 3 supports two horizontal tubes 4 at the same time, and two arc-shaped wear-resistant pads 32 are set on the arc-shaped support plate 3 to effectively protect the horizontal tubes 4 and the arc-shaped support plate 3. Adjacent horizontal tubes 4 are connected end to end by plug-in pipes 42, and the elliptical through grooves 421 on the plug-in pipes 42 are connected to the J-shaped support tube 1 to facilitate the connection of cables inside the tube and to assist in the installation of other equipment.

A corrugated plate 7 is then embedded into the angular groove 521 of the fixing block 52 and secured with bolts 72 to the through-ribs 6. This allows the road and bridge guardrail bracket to achieve a prefabricated assembly effect, significantly saving manpower and time costs, facilitating construction and subsequent maintenance. The overall structure is highly stable and can effectively resist various external forces, ensuring the long-term stability and reliability of the guardrail.
