[0023] Please refer to Figure 1 and Figure 2 A side structure of a bridge in a preferred embodiment provided by the present invention includes a bridge body 100, a protective pier 200, a vertical rod 300, a top railing 400, a connection seat 500, a retrofit assembly 600, and a reinforcement member 700.

[0024] The protective pier 200 is provided on the side of the bridge body 100 and protrudes from the upper surface of the bridge body 100.

[0025] The vertical rod 300 is connected to the top of the protective pier 200, and the vertical rods 300 are arranged along the length direction of the protective pier 200. In this embodiment, the length direction of the protective pier 200 is Figure 3 the left - right direction. The top railing 400 extends along the length direction of the protective pier 200 to connect a plurality of vertical rods 300 in series. The connection seat 500 is connected to the protective pier 200, and the connection seat 500 is provided with a mounting plate 510 that extends from the gap between the vertical rods 300 to the outside of the vertical rods 300. Here, the outside refers to the side away from the center position of the bridge body 100, and the side close to the center position of the bridge body 100 is the inside. The bottom of the retrofit assembly 600 is fixedly installed on the mounting plate 510, and the retrofit assembly 600 includes, but is not limited to, a billboard or a sound barrier. One end of the reinforcement member 700 is connected to the retrofit assembly 600, and the other end is connected to the top railing 400. It can be understood that a plurality of connection seats 500 and reinforcement members 700 can be arranged along the length direction of the protective pier 200, so as to provide multiple positions for installing and fixing the retrofit assembly 600.

[0026] Wherein the mounting plate 510 is connected with a vertical plate �40, the vertical plate 540 extends to the inside of the top railing 400, the reinforcement member 700 is provided with a holding part 710, the holding part 710 is provided with an arc groove 711 for the top railing 400 to be embedded, and the holding part 710 and the vertical plate 540 are connected and fixed by a third fastener to hold the top railing 400 tightly. Thus, the reinforcement of the retrofit assembly 600 is realized to improve its installation stability and wind resistance. And the holding part 710 is not only connected to the top railing 400, but also connected to the vertical plate 540. Therefore, the acting force will not only be transmitted to the top railing 400, but also be transmitted to the vertical plate 540, the mounting plate 510, the clamping plate 530 and finally to the protective pier 200, so that the acting force received by the retrofit assembly 600 will not be overly concentrated on the top railing 400, avoiding structural damage caused by stress concentration and improving the structural life and reliability. Specifically, the third fastener can be a combination of a bolt and a nut.

[0027] A side structure of a bridge provided by the present invention forms a stable protection structure through the combination of a protection pier 200 and a vertical rod 300. The protection pier 200 protrudes from the upper surface of the bridge body 100, which can effectively prevent vehicles from rushing out of the bridge deck. The series design of the vertical rod 300 and the top railing 400 further enhances the protection ability and ensures the safety of the bridge side. The additional component 600 is fixed on the protection pier 200 through a connecting seat 500 and a mounting plate 510, and the mounting plate 510 is outside the vertical rod 300, avoiding occupying the effective passing width of the bridge deck. Also, through a reasonable structural layout, the additional component 600 is not directly installed on the surface of the bridge body, reducing the damage to the bridge surface. At most, only holes need to be drilled on the protection pier 200 to install fasteners, rather than drilling on the bridge surface. The additional component 600 can be designed individually according to needs. The reinforcement member 700 further enhances the connection stability between the additional component 600 and the top railing 400, improving the wind resistance and vibration resistance of the additional component 600. The side structure of the present invention not only provides safety protection but also can integrate other functions according to needs, such as lighting, advertising display, greening, sound insulation, etc. The additional component 600 can be a functional structural component such as a lighting bracket, a billboard, a sound insulation barrier, etc. Of course, the additional component 600 can also be a device integrating multiple functions, such as a sound insulation barrier with lighting.

[0028] Referring to Figure 2 and Figure 7 In some embodiments of the present invention, the connecting seat 500 includes a fitting plate 520 that fits against the inner side of the protection pier 200. The upper end of the fitting plate 520 is fixedly connected to the mounting plate 510. The side of the mounting plate 510 facing away from the fitting plate 520 extends outside the protection pier 200 and is fixedly connected to the bottom of the additional component 600, so that the additional component 600 does not occupy the space of the bridge deck after installation. A clamping plate 530 is attached to the side of the protection pier 200 facing away from the fitting plate 520. The clamping plate 530, the protection pier 200, and the fitting plate 520 are provided with corresponding holes for connection and fixation through a first fastener, thereby firmly fixing the fitting plate 520 on the protection pier 200. Specifically, the first fastener can be a combination of a bolt and a nut.

[0029] Referring to Figure 2 and Figure 7, in a further embodiment of the present invention, a connecting plate 531 is provided at the upper end of the clamping plate 530. The bottom of the additional component 600, the mounting plate 510, and the connecting plate 531 are sequentially attached from top to bottom and are provided with corresponding holes for connection and fixation by a set of second fasteners. Thus, the connection of the three is achieved through the same set of second fasteners. This not only realizes the connection between the additional component 600 and the mounting plate 510, achieving the installation and fixation of the additional component 600, but also realizes the connection between the mounting plate 510 and the connecting plate 531 at the upper end of the clamping plate 530, so that the upper end of the clamping plate 530 is connected and fixed to the mounting plate 510. Then, in cooperation with the first fasteners, multi-position connection is achieved, improving the connection stability between the connecting seat 500 and the protection pier 200, and also avoiding the problem that the end of the mounting plate 510 is prone to deformation due to its excessive extension. Thus, a stable installation foundation is also provided for the additional component 600. Specifically, the second fastener can be a combination of a bolt and a nut.

[0030] Refer to Figure 2 and Figure 7 , in a further embodiment of the present invention, a first reinforcing rib 532 is provided between the clamping plate 530 and the connecting plate 531 to improve the bearing capacity of the connecting plate 531 and prevent the connecting plate 531 from deforming or even being damaged due to bearing the gravity of the additional component 600.

[0031] Refer to Figure 2 and Figure 7 , in a further embodiment of the present invention, second reinforcing ribs 541 are provided between both the inner and outer sides of the vertical plate 540 and the mounting plate 510 to improve the structural strength of the vertical plate 540 in the lateral force direction.

[0032] Refer to Figure 3 , Figure 4 , Figure 5 and Figure 6In some embodiments of the present invention, the additional assembly 600 is a soundproof barrier, and the additional assembly 600 includes columns 610 and baffles 620. The columns 610 are arranged at intervals along the length of the protective pier 200. The columns 610 are provided with mounting slots 611, and the openings of the mounting slots 611 of two adjacent columns 610 are arranged opposite each other. The bottom of the columns 610 is connected and fixed to the mounting plate 510. Specifically, the bottom of the columns 610 is provided with a base plate, and the base plate and the mounting plate 510 are provided with corresponding holes for connection and fixation via fasteners. The connecting seat 500 and the reinforcement 700 are provided in a one-to-one correspondence with the columns 610, thereby achieving connection, fixation and reinforcement of the bottom of each column 610. When the cam 611 is in the closed position, the cam 611 is in the closed position, and the cam 611 is in the closed position, so that the cam 611 can be adjusted. Baffle 620 can reduce the impact of noise on the surrounding environment and can be made of foamed aluminum to achieve lightweight and improve sound insulation. During installation, the clamping plate 720 can be installed from the upper end of the column 610, so that the inner side wall of the installation groove 611 fits into the clamping groove 721. The clamping plate 720 can be raised and lowered to the desired position.

[0033] Reference Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 In some embodiments of the present invention, the mounting assembly 600 further includes a capping member 630 , a pre-tightening limit member 650 and an adjusting screw 660 .

[0034] The capping member 630 is fixedly installed at the upper end of the column 610. The bottom of the capping member 630 is embedded in the installation groove 611. The top of the capping member 630 is provided with an inclined shielding portion 631 that extends upward and inwardly; an auxiliary lighting lamp can be installed at the top of the inclined shielding portion 631. A photovoltaic panel 640 can be installed on the outer side of the inclined shielding portion 631. Usually, a storage battery is configured to store the electric energy converted by the photovoltaic panel 640, so as to supply power to the auxiliary lighting lamp. Of course, the auxiliary lighting lamp can also be connected to an external power supply line through a wire to provide electric energy when the electric energy of the storage battery is insufficient, thus saving energy and being environmentally friendly. The inclined shielding portion 631 can be provided with an installation frame 632 for connecting the photovoltaic panel 640. The inclined shielding portion 631 of the capping member 630 improves the sound insulation coverage range and at the same time enables the baffle 620 to be fixed in the installation groove 611. Pre-tightening limit members 650 are arranged on both sides of the baffle 620, and the pre-tightening limit members 650 are movably installed at the upper end of the corresponding installation groove 611; the bottom of the capping member 630 is provided with an installation block 633 that is embedded in the installation groove 611, and the installation block 633 is provided with a limit hole 634 for the adjusting screw 660 to pass through; the inner edges of the left and right sides of the baffle 620 are provided with first inclined surfaces 621, and the two first inclined surfaces 621 converge and approach inwardly; the pre-tightening limit member 650 is provided with a first fitting surface 651, the bottom of the capping member 630 is provided with a limit block 635 that is embedded in the installation groove 611, the bottom of the limit block 635 is provided with a second inclined surface 636, and the limit block 635 is provided with a limit notch 637 above the second inclined surface 636; the adjusting screw 660 is threadedly connected to the side wall of the installation groove 611 and is used to push the pre-tightening limit member 650 into contact with the baffle 620, and push a part of the first fitting surface 651 to fit with the first inclined surface 621 and a part to fit with the second inclined surface 636, so that the outer side of the baffle 620 is closely attached to the side wall of the installation groove 611, and the baffle 620 and the limit block 635 are clamped by the pre-tightening limit members 650 on both sides; the top of the pre-tightening limit member 650 is provided with a limit convex block 652 that is embedded in the limit notch 637. Specifically, the inner side wall of the installation groove 611 is provided with a first threaded hole 613 for the adjusting screw 660 to be threadedly connected, so as to push the pre-tightening limit member 650 to move outward. By pushing the pre-tightening limit member 650 into contact with the baffle 620 through the adjusting screw 660, the stable clamping of the baffle 620 is realized.The adjusting screw 660 can be adjusted in position by screwing to push the pre-tightening limiting member 650 to move outwards; the first inclined surface 621 of the baffle 620 is combined with the first fitting surface 651 on the pre-tightening limiting member 650. When the first fitting surface 651 is in close contact with the first inclined surface 621, it will push the baffle 620 to move outwards and be in close contact with the side wall of the installation groove 611. At the same time, the baffle 620 also has a tendency to move towards the pre-tightening limiting member 650 on the other side, and the pre-tightening limiting member 650 on the other side will also press the baffle 620, so that the baffle 620 is clamped left and right by the pre-tightening limiting members 650 on both sides, thereby realizing pre-tightening and clearance elimination in two directions. And due to the characteristics of the first inclined surface 621, the greater the pushing force of the pre-tightening limiting member 650, the better the pre-tightening effect, and the pre-tightening adjustment can be carried out according to actual needs. In addition, the first fitting surface 651 will also be in contact with the second inclined surface 636, and cooperate with the rear side wall of the installation groove 611 to clamp and fix the limiting block 635 at the same time, realizing the multi-position fixation of the capping member 630, avoiding the capping member 630 being limited and fixed only by the adjusting screw 660 passing through the limiting hole, and improving the installation and fixation stability of the capping member 630. Using the pre-tightening limiting member 650 can ensure that the baffle 620 and the capping member 630 are closely combined with the column 610 after installation, effectively avoiding the loosening and noise of the baffle 620 caused by vehicle vibration or external force. Then, by embedding the limiting convex block 652 into the limiting notch 637, multi-position vertical limiting and fixing of the limiting block 635 is realized, further improving the installation accuracy and installation stability of the capping member 630. It can be understood that in order to reduce the installation gap, the bottom surface of the limiting block 635 is in contact with the upper end surface of the uppermost baffle 620 or a rubber pad is clamped. The main function of the adjusting screw 660 is to push the pre-tightening limiting member 650 to move to clamp the baffle 620 and the limiting block 635. The capping member 630 realizes the limiting and fixing by the adjusting screw 660 passing through the limiting hole and the adjusting screw 660 pushing the limiting block 635 to be embedded into the limiting notch 637, so that the adjusting screw 660 has multiple functions, making the structure more ingenious and the installation and disassembly simpler.

[0035] Referring to Figure 11 , in some embodiments of the present invention, the side wall of the limiting block 635 is in contact with one side wall of the installation groove 611; the side wall of the installation block 633 is in contact with the other side wall of the installation groove 611. Specifically, the side wall of the limiting block 635 is in contact with the outer side wall of the installation groove 611; the side wall of the installation block 633 is in contact with the inner side wall of the installation groove 611. The two sets of contact side walls further optimize the installation accuracy and stability of the capping member 630. The overturning moment of the capping member 630 can be partially removed through the front and rear side walls of the installation groove 611, avoiding stress concentration, improving the overall structural strength of the sound barrier, and reducing the vibration and loosening problems caused by the installation gap.

[0036] In a specific embodiment of the present invention, a first guide rail 612 is provided on the side wall of the installation groove 611, and the pre-tightening limiting member 650 is provided with a first sliding groove 653 adapted to the first guide rail 612. This enables the pre-tightening limiting member 650 to slide smoothly along the first guide rail 612, improving the installation accuracy of the pre-tightening limiting member 650. Moreover, through the limiting effect of the first sliding groove 653, the stability of the pre-tightening limiting member 650 during the adjustment process is ensured. It can be understood that for the convenience of installation, there is a spacing for the pre-tightening limiting member 650 to be embedded between the outer end of the first guide rail 612 and the side wall of the installation groove 611 facing outward. This spacing is sufficient for the first sliding groove to align with the first guide rail after the pre-tightening limiting member is embedded, and then the pre-tightening limiting member is moved so that the first guide rail is embedded in the first sliding groove, thereby achieving the installation. It can be understood that during installation, the installation block will avoid the first guide rail and be embedded in the installation groove. For the convenience of disassembly, as Figure 11 shown, after installation, there is a spacing greater than the size of the limiting block protrusion between the inner side of the pre-tightening limiting member 650 and the installation block 633. As a result, during disassembly, there is sufficient space on the inner side of the pre-tightening limiting member for the pre-tightening limiting member to move inward so that the limiting convex block disengages from the limiting notch, releasing the limiting lock on the capping member.

[0037] Refer to Figure 5 and Figure 6, in some embodiments of the present invention, it further includes a pre-tightening member 670; there are multiple baffles 620 which are vertically stacked; the pre-tightening member 670 is correspondingly arranged at the splicing positions of the upper and lower adjacent baffles 620 and the lower end position of the lowermost baffle 620; that is, the upper end of the uppermost baffle 620 is clamped and fixed by the pre-tightening and limiting member 650, and the upper and lower end positions on the left and right sides of all other baffles 620 are clamped and fixed by the pre-tightening member 670, and the adjacent positions of the upper and lower adjacent baffles 620 can share the pre-tightening member 670, thereby reducing the number of pre-tightening members 670 and simplifying the installation. The splicing position is the lower end of the upper baffle 620 and the upper end of the lower baffle 620. The pre-tightening member 670 is located on the left and right sides of the baffle 620; the pre-tightening member 670 is movably installed in the corresponding mounting groove 611; the inner side wall of the mounting groove 611 is provided with a second threaded hole, and a screw is threadedly connected to the second threaded hole. The screw is used to push the pre-tightening member 670 into contact with the corresponding baffle 620, and a mutual acting force is generated at the contact position, thereby pressing the baffle 620. Specifically, the side wall of the mounting groove 611 is provided with a second guide rail, and the pre-tightening member 670 is provided with a second sliding groove adapted to the second guide rail. The pre-tightening member 670 is provided with a second fitting surface 671 that fits the first inclined surface 621; thereby, the second fitting surface 671 is used to clamp and fix the baffle 620 by the pre-tightening members 670 on both sides, eliminating the installation gap.
