[0017] Reference Figures 1 to 5 This utility model discloses a clamp-type bridge crash barrier sound barrier mounting base, including a lower clamp 2, a set screw 3, a column 4, an upper clamp 5, and a locking bolt 6. The lower clamp 2 is configured to clamp the opposite ends of the bridge crash barrier 1, and the lower clamp 2 has a threaded hole 21 perpendicular to the clamping surface. The set screw 3 is installed in the threaded hole 21, and the end of the set screw 3 can be pressed against the mounting groove 11. The set screw 3 is configured to provide anchoring force to prevent the lower clamp 2 from slipping. The column 4 is arranged at the upper end of the lower clamp 2 in a vertical direction. The upper clamp 5 is arranged at the upper end of the lower clamp 2 and is configured to clamp the opposite ends of the column 4. The locking bolt 6 passes through the upper clamp 5 and the column 4, and the locking bolt 6 pulls and locks the upper clamp 5, the column 4, and the lower clamp 2 together, so that the lower clamp 2 is clamped and fixed on the crash barrier 1.

[0018] This utility model relates to a clamp-type bridge crash barrier sound barrier installation base, mainly applied to crash barriers 1 installed along the edge of a bridge. Specifically, the crash barrier 1 is vertically installed at the edge of the bridge's driving lane and extends along the bridge. An installation groove 11 is pre-drilled on the side wall of the crash barrier 1. This installation groove 11 is a shallow hole with controlled depth, less than the thickness of the concrete protective layer, thereby avoiding damage to the internal steel reinforcement of the barrier. This achieves minimal damage installation to the original barrier structure, effectively ensuring the safety and durability of the main structure.

[0019] like Figure 1 and Figure 2 As shown, the lower clamp 2 is fitted onto the upper end of the crash barrier 1 in a clamping manner, with a vertically arranged column 4 on its upper part. The upper clamp 5 is installed on the upper end of the lower clamp 2 and clamps the outside of the column 4. The clamping arm 22 of the lower clamp 2 has a threaded hole 21, and the set screw 3 is installed in the threaded hole 21. One end of the set screw 3 abuts against the outside of the lower clamp 2, and the other end passes through the clamp and extends into the mounting groove 11 of the crash barrier 1, and is finally tightened to the bottom of the mounting groove 11. The locking bolt 6 is horizontally set, passing through the upper clamp 5 and the column 4, and the upper clamp 5, the column 4 and the lower clamp 2 are tightly connected by tightening the nut, thereby firmly holding the entire system to the crash barrier 1. This utility model combines the clamping effect generated by the locking bolt 6 with the local anchoring provided by the set screw 3 to form a dual fixing mechanism with clear primary and secondary components, which can achieve reliable and efficient installation of the sound barrier without damaging the original guardrail structure.

[0020] In some specific embodiments of this utility model, the lower clamp 2 includes two symmetrically arranged clamping arms 22, which are respectively arranged at opposite ends of the crash barrier 1. The clamping arms 22 are L-shaped and adapted to the contour of the crash barrier 1. The upper clamp includes two symmetrically arranged clamping panels 53, which are respectively arranged at opposite ends of the column 4.

[0021] like Figure 1 and Figure 5 As shown, the lower clamp 2 consists of a pair of symmetrically arranged L-shaped clamping arms 22. Each L-shaped clamp has a vertical clamping arm 22 and a horizontal supporting arm. The inner contour formed by the vertical clamping arm 22 and the horizontal clamping arm 22 is adapted to the outer contour of the corner of the crash barrier 1. Thus, the two L-shaped clamping arms 22 can tightly cover the sides and top surface of the crash barrier 1, thereby achieving stable initial positioning and load-bearing. Correspondingly, the upper clamp 5 consists of a pair of symmetrically arranged clamping panels 53. The pair of clamping panels 53 are respectively set on the left and right sides of the column 4. Their inner sidewalls are in contact with the outer surface of the column 4. Through the pulling action of the horizontal locking bolts 6, the clamping panels 53 on both sides can clamp inward simultaneously, thereby firmly fixing the column 4 above the lower clamp 2.

[0022] The upper clamp 5 and the lower clamp 2 together form a self-balancing force system. The L-shaped structure of the lower clamp 2 mainly bears the vertical load and provides anti-overturning moment, while the flat plate structure of the upper clamp 5 is responsible for clamping the column 4 and transmitting the horizontal load. The two work together through the locking bolt 6 to form a reliable connection node with a simple structure and convenient installation.

[0023] In some specific embodiments of this utility model, the column 4 is an I-beam, which includes a web 43 and flanges 44 vertically arranged at opposite ends of the web 43. The bottom of the flanges 44 is supported on the lower clamp 2, and the flanges 44 are in contact with the clamping surface of the upper clamp 5.

[0024] like Figure 4 As shown, the I-beam is vertically installed in the reserved slot between the two clamping panels 53. Its web 43 is arranged perpendicular to the clamping panels 53, and the flanges 44 at both ends are parallel to the clamping panels 53, forming a large-area stable contact with the inner surface of the corresponding clamping panels 53. The locking bolts 6 horizontally penetrate the reserved holes in the clamping panels 53 and the corresponding holes in the flanges 44, and by applying preload, the upper clamp 5, the I-beam flanges 44, and the lower clamp 2 are pressed together into an integral load-bearing structure. This structure fully utilizes the material advantages of the I-beam, such as its large moment of inertia and outstanding bending resistance, enabling the column 4 to efficiently bear the bending moment and wind load transmitted by the sound barrier.

[0025] It should be noted that the web plate 43 of the I-beam and the two side flanges 44 together form a vertical limiting groove. This limiting groove structure provides a reliable installation interface for the sound barrier panel. The sound barrier panel can be directly inserted into or fixed in the groove through connectors, realizing the rapid and precise docking of the sound barrier system and the supporting structure.

[0026] In some specific embodiments of this utility model, a widening plate 41 is provided at the bottom of the wing plate 44. The widening plate 41 is perpendicular to the wing plate 44. The widening plate 41 is attached to the clamping surface of the upper clamp 5 and connected to the upper clamp 5 by the locking bolt 6.

[0027] like Figure 3 As shown, the bottom of the wing plate 44 extends symmetrically to the left and right sides along its length to form a widening plate 41. The widening plate 41 is located within the coverage area of ​​the clamping panel 53, ensuring that the clamping force applied by the clamping panel 53 can be evenly transmitted to the full width of the widening plate 41. By increasing the pressure area, plastic deformation or loosening of the connection caused by local stress concentration of the wing plate 44 is avoided, thereby improving the load-bearing stability and fatigue life of the node.

[0028] Furthermore, the widened plate 41 and the column 4 are formed by welding or integral casting to ensure the strength and reliability of the connection.

[0029] In some specific embodiments of this utility model, the column 4 is horizontally provided with stiffening ribs 42, which connect between the two wing plates 44 and span between the widening plate 41 and the wing plates 44. For example... Figures 3 to 5 As shown, stiffening ribs 42 are disposed within the limiting groove formed by the flanges 44 and the web 43. The stiffening ribs 42 extend horizontally and are vertically connected between the flanges 44 on both sides, while also bridging the flanges 44 and their extended widening plates 41. This structure effectively enhances the connection stiffness between the widening plate 41 and the main body of the column 4, significantly improving the overall stability and deformation resistance of the base. Simultaneously, it allows the bending moment load transmitted by the sound barrier to be effectively dispersed through the stiffening ribs 42, avoiding stress concentration. This significantly reduces the risk of fatigue damage at the connection points under long-term wind loads and vibration, ensuring the long-term safety and durability of the sound barrier installation structure.

[0030] In some specific embodiments of this utility model, multiple stiffening ribs 42 are evenly arranged in the vertical direction, and multiple locking bolts 6 are evenly arranged in the vertical direction. The multiple stiffening ribs 42 and multiple locking bolts 6 are arranged alternately in the vertical direction. like Figure 2 and Figure 3As shown, the stiffening ribs 42 and locking bolts 6 are arranged alternately in the vertical direction. Specifically, multiple stiffening ribs 42 are evenly distributed along the height of the column 4, while multiple sets of locking bolts 6 are also evenly arranged in the vertical direction. The two are spatially staggered, forming an alternating arrangement. This layout creates multiple continuous stiffness-enhancing zones and pressure-tightening zones in the vertical direction of the column 4. The stiffening ribs 42 are responsible for improving the local stiffness and bending resistance of the column 4 itself, while the locking bolts 6 ensure that the upper clamp 5 and the lower clamp 2 can evenly transmit the clamping force to the column 4. The alternating arrangement of the two makes the structural stiffness and connection strength uniformly and continuously strengthened in the vertical direction, effectively avoiding local weak points that may occur due to the intermittent arrangement of components.

[0031] In some specific embodiments of this utility model, the upper clamp 5 is provided with a reinforcing rib 51, which is connected to the lower clamp 2, and the reinforcing rib 51 is located at the end of the upper clamp 5 away from the column 4. For example... Figure 5 As shown, multiple reinforcing ribs 51 are evenly arranged along the left-right direction on the clamping panel 53. All reinforcing ribs 51 are located at the end of the clamping panel 53 furthest from the column 4. By setting the reinforcing ribs 51, the bending stiffness of the cantilever end of the clamping panel 53 can be enhanced, preventing warping or deformation under the high preload of the locking bolts 6. Simultaneously, the reinforcing ribs 51 connect the upper clamp 5 and the lower clamp 2 into a single unit, forming a stable triangular support structure, thereby improving the stability of the entire base connection and the load distribution efficiency.

[0032] In some specific embodiments of this utility model, a gasket 52 is provided on the clamping surface of the upper clamp 5. The gasket 52 is attached to the wall surface of the widened plate 41 and the column 4 and is located between the column 4 and the upper clamp 5. It should be noted that the gasket 52 is made of elastic wear-resistant material. Its placement between the upper clamp 5 and the column 4 can effectively increase the friction between the contact surfaces and improve the anti-slip capability. At the same time, the elastic deformation of the gasket 52 can compensate for the micro-unevenness of the contact surface, ensuring that the preload of the locking bolt 6 is evenly distributed and avoiding component damage caused by local stress concentration.

[0033] The following reference Figures 1 to 5 The structure shown further illustrates the mounting base for this clamp-type bridge crash barrier sound barrier.

[0034] In this specific embodiment, the column 4 is made of I-beams, and its web 43 and the two side flanges 44 together form two limiting grooves. Three stiffening ribs 42 are evenly arranged vertically in each limiting groove. These stiffening ribs 42 extend horizontally and are vertically welded between the corresponding flange 44 and the widening plate 41. The upper clamp 5 and the lower clamp 2 are locked together by four sets of locking bolts 6. A set of bolts is evenly distributed between two adjacent stiffening ribs 42, thus forming an optimized layout in which the stiffness reinforcement zone and the bolt fastening zone are alternately distributed vertically. The lower clamp 2 includes two clamping arms 22, and five internal hexagonal recessed set screws are evenly arranged on the clamping arms 22. The set screws are tightened into the shallow holes in the side wall of the crash barrier 1, and together with the horizontal locking bolts 6, they form a dual anti-slip fixing structure with a clear distinction between primary and secondary components. The upper clamp 5 includes two clamping panels 53. Each clamping panel 53 has three reinforcing ribs 51 evenly arranged on its outer side along the left-right direction. These reinforcing ribs 51 are rigidly connected to the clamping arm 22 on the corresponding side to enhance the structural rigidity and stability of the cantilever end of the clamping panel 53 and prevent it from deforming under stress.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
