First of all, it should be noted that the longitudinal direction of the bridge in the present application refers to the extension direction of the bridge, while the transverse direction of the bridge refers to the width direction of the bridge; which is different from the ordinary anti-collision guardrail in the prior art, which is directly arranged at the mid-span of the widened bridge 30 to connect the new bridge 310 and the old bridge. In this way, when uneven settlement occurs between the old bridge and the new bridge 310 in the widened bridge 30, the anti-collision guardrail will be damaged, resulting in the problem of vertical deformation of the anti-collision guardrail. The present application solves the above-mentioned defects in the prior art by providing an anti-collision guardrail for unevenly settled bridges and a widened bridge 30 structure. The details are as follows:

[0034] Specifically, the anti-collision guardrail for unevenly settled bridges in the present application includes a plurality of anti-collision support structures 10 spaced apart along the longitudinal direction of the bridge and a plurality of anti-collision components 20 extending along the longitudinal direction of the bridge. The anti-collision support structure 10 is used for the installation of the anti-collision component 20 and serves as a support body for the anti-collision component 20; the anti-collision component 20 is used for anti-collision, serves as a lane separator and prevents vehicles and pedestrians from rushing out of the guardrail, and its two ends are respectively connected to two adjacent anti-collision support structures 10, thereby forming an anti-collision guardrail.

[0035] Each of the anti-collision support structures 10 includes two anti-collision support units 110 arranged opposite to each other in the transverse direction of the bridge and a plurality of connection components 120 arranged at intervals in the vertical direction. The two anti-collision support units 110 are used to be respectively arranged on the new bridge 310 and the old bridge 320, and the connection components 120 connect the two anti-collision support units 110 as a whole to achieve coordinated deformation and thus avoid uneven settlement. Each of the anti-collision support units 110 includes a base 111, a transverse support vertical plate 112 and a longitudinal anti-collision vertical plate 113. The base 111 is used to be fixedly connected to the bridge deck and to be used for the installation of the transverse support vertical plate 112 and the longitudinal anti-collision vertical plate 113. Considering the convenience of construction and the fastening and tightening, a plurality of bolt holes are opened on the base 111 to fix the base 111 on the bridge deck by means of a through-connection method of fastening bolts 114. Each of the anti-collision support structures 1 0, the two bases 111 are respectively fixed on the bridge decks of the new bridge 310 and the old bridge 320; the transverse supporting upright plate 112 extends in the transverse direction of the bridge to facilitate the installation and connection of the connecting component 120, thereby increasing the connection contact surface and ensuring the stability of the connection, and it is fixedly connected to the inner side of the longitudinal anti-collision upright plate 113 to improve the transverse structural strength of the longitudinal anti-collision upright plate 113 and avoid deformation in the transverse direction, thereby forming a T-shaped cross-section structure with light weight, material saving, and sufficient strength; and the longitudinal anti-collision upright plate 113 is used for the installation of the anti-collision component 20, and its longitudinal extension can increase the installation surface, facilitate the connection and tightening effect when installing the anti-collision component 20, and at the same time improve the installation portability for construction, and can also make one longitudinal anti-collision upright plate 113 simultaneously for the installation of two anti-collision components 20, and the two ends of the anti-collision component 20 are respectively connected to the two adjacent longitudinal anti-collision upright plates 113.

[0036] As a preferred embodiment of the utility model, each of the connecting components 120 includes two connecting plates 121 arranged opposite to each other along the longitudinal bridge direction and a plurality of connecting bolts 122. The connecting plates 121 are provided with connecting holes arranged opposite to each other along the transverse bridge direction. The transverse supporting vertical plates 112 are provided with first through holes arranged one-to-one corresponding to the connecting holes. The connecting bolts 122 pass through the connecting holes and the first through holes to fix the two connecting plates 121 to the two sides of the transverse supporting vertical plates 112 respectively, and the two ends of the connecting plate 121 are respectively connected to the two transverse supporting vertical plates 112 arranged opposite to each other along the transverse direction.

[0037] It should be noted that the connecting plate 121 is used to connect the two horizontal supporting vertical plates 112 that are spaced apart into one body, and then fixed by the connecting bolts 122. The multiple connecting plates 121 are arranged along the vertical intervals to ensure that the connection stiffness can be evenly guaranteed from top to bottom, improve the degree of integration, and increase the coordination of uniform settlement. The connection method using the connecting bolts 122 is convenient and fast, and it is easier to disassemble during later maintenance and replacement.

[0038] As a preferred embodiment of the present utility model, the anti-collision assembly 20 includes a plurality of anti-collision units arranged at intervals along the vertical direction, each of the anti-collision units includes two longitudinal anti-collision columns 210 arranged opposite to each other along the horizontal direction, the two longitudinal anti-collision columns 210 are respectively arranged on the outer sides of the two longitudinal anti-collision vertical plates 113 arranged opposite to each other along the horizontal direction, and the two ends of each longitudinal anti-collision column 210 are respectively connected to the longitudinal anti-collision vertical plates 113 of the two adjacent anti-collision support structures 10.

[0039] It should be noted that the anti-collision assembly 20 includes a plurality of anti-collision units arranged at vertical intervals to ensure sufficient upper and lower anti-collision heights, and each of the anti-collision units includes two longitudinal anti-collision columns 210 arranged opposite to each other in the transverse direction, and are respectively arranged on the outer sides of the two longitudinal anti-collision vertical plates 113 arranged opposite to each other in the transverse direction, so as to serve as the mid-span anti-collision assembly 20 of the new bridge 310 and the old bridge 320 respectively, where the outer side refers to the side away from each other between the two longitudinal anti-collision vertical plates 113.

[0040] As a preferred embodiment of the utility model, it also includes a plurality of mounting pads 220 and mounting bolts 230 arranged at intervals along the longitudinal direction, the mounting pads 220 are provided with a plurality of mounting holes, the longitudinal anti-collision vertical plate 113 is provided with a plurality of second through holes 1131 arranged one-to-one corresponding to the mounting holes, the mounting pads 220 are connected to the outer side of the longitudinal anti-collision vertical plate 113 by the mounting bolts 230 that penetrate the mounting holes and the second through holes in sequence, and the longitudinal anti-collision column 210 is fixed on the mounting pads 220.

[0041] It is worth mentioning that the mounting pad 220 can reduce the pressure between the mounting bolts 230 and the longitudinal anti-collision vertical plate 113, and ensure the stability and reliability of the connection, thereby avoiding damage or deformation caused by pressure and extrusion during the bolt connection process, and the mounting pad 220 can play a buffering role; at the same time, it is used for the installation of the longitudinal anti-collision column 210, and is connected by welding. The construction is convenient, firm and reliable, and the longitudinal anti-collision column 210 does not need to be in direct contact with the longitudinal anti-collision vertical plate 113 during installation, thereby reducing the loss generated during installation.

[0042] Furthermore, the second through hole 1131 is elliptical.

[0043] It should be noted that the elliptical shape allows the structure to be easily deformed in a small range in the longitudinal direction, thereby facilitating a small longitudinal displacement movement in the elliptical hole, thereby increasing the deformation adaptation range and providing protection for the longitudinal anti-collision vertical plate 113 .

[0044] As a preferred embodiment of the present utility model, the number of the anti-collision units is three, and the three anti-collision units are arranged at intervals along the vertical direction.

[0045] It is worth noting that the number of the anti-collision units can be determined based on the height of the longitudinal anti-collision vertical plate 113 and the height range to be protected. Preferably, the number of the anti-collision units is three, and technical personnel in this field can choose according to actual needs.

[0046] Furthermore, the mounting holes are distributed in a matrix along the circumference of the mounting pad 220 .

[0047] It should be noted that the matrix distribution can better ensure that the four sides of the mounting pad 220 can be fixed on the longitudinal mounting vertical plate, thereby improving the connection stability.

[0048] Furthermore, the height of each connecting plate 121 is 45 mm to 50 mm.

[0049] It should be understood that the height of the connecting plate 121 needs to match the size of the connecting bolt 122 to ensure that the connecting bolt 122 can be easily penetrated and fixed, and the height does not need to be too large to save costs. The connecting plates 121 are arranged at certain intervals to ensure uniform connection coordination stiffness. Preferably, the height of each connecting plate 121 can be set to 45mm~50mm.

[0050] The present application also provides a structure of a widened bridge 30, including a widened bridge 30, wherein the widened bridge 30 includes a new bridge 310 and an old bridge 320, and also includes an anti-collision guardrail for uneven settlement bridges as described above, wherein bases 111 arranged relatively along the transverse direction of the bridge in the anti-collision guardrail are respectively fixed on the bridge decks of the new bridge 310 and the old bridge 320.

[0051] In a preferred embodiment, it also includes a concrete curbstone 330, which extends longitudinally and is respectively arranged on the bridge deck of the new bridge 310 and the old bridge 320, and a longitudinal seam 340 is formed between the new bridge 310 and the old bridge 320. The base 111 in the anti-collision guardrail is connected to the concrete curbstone 330 by fastening bolts 114 that penetrate the bolt holes and the concrete curbstone 330 in sequence and extend into the bridge deck.

[0052] It should be noted that in the partially widened bridge 30, the mid-span portion uses a concrete curb 330 to span across the new bridge 310 and the old bridge 320 to separate them and form a longitudinal seam 340. Therefore, when setting the anti-collision guardrail of the present application, in order to ensure uniform settlement force on both sides, the two bases 111 in each of the anti-collision support structures 10 need to be respectively set on the concrete curb 330 of the new bridge 310 and the old bridge 320, and the fastening bolts 114 are passed through the bolt holes and the concrete curb 330 in sequence and extended into the bridge deck to be connected to the concrete curb 330; the distance between the bases 111 needs to be set accordingly according to the size of the longitudinal seam, and the length of the connecting plate 121 in the connecting assembly 120 may need to be adjusted synchronously.

[0053] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
