[0044] like Figure 1-Figure 6 As shown, the assembled bridge guardrail includes: a crossbeam 1 for providing anti-collision protection for the bridge, and a column 2 for fixed connection with the bridge deck to be installed, and the side of the column 2 is fixedly connected to the crossbeam 1. It also includes: an assembly seat 3 for facilitating the fixed connection between the column 2 and the bridge deck to be installed, the middle part of the assembly seat 3 is assembled and connected with the column 2; the bottom of the assembly seat 3 is fixedly connected with the bridge deck to be installed. Through the transition of the assembly seat 3, the connection between the column 2 and the bridge deck to be installed can be conveniently achieved.

[0045] In order to improve the fixed connection strength of the column 2, the column 2 includes: a front wall 21, a rear wall 22 and a side wall 23, and the front wall 21 and the rear wall 22 are fixedly connected or integrally formed by the side wall 23 respectively;

[0046] In order to ensure the fixed connection strength of the column 2 and the anti-collision strength of the column 2, the lower ends of the front wall 21 and the rear wall 22 are bent in opposite directions to form a pressure wall 24, and the lower end of the side wall 23 exceeds the lower side of the pressure wall 24 to form a limiting wall 25, which is adapted to the limited groove opened on the bridge deck to be installed, and the limiting wall 25 extends into the limiting groove. By setting the pressure wall 24, the compression and fixing strength of the column 2 can be improved. By setting the limiting wall 25, the position of the column on the bridge deck to be installed can be accurately positioned, and the limiting effect of the limiting groove can also better guarantee the fixing strength of the column 2.

[0047] In order to improve the connection stability of the column 2, especially to improve the support strength and ensure the anti-collision effect, the assembly seat 3 includes: a pressing member 31 for pressing and fixing the pressure wall 24 and a supporting member 32 for supporting the side wall 23. The pressing member 31 is pressed and fixedly connected to the upper surface of the pressure wall 24, the supporting member 32 is fixedly connected to the side wall 23, and the lower end of the supporting member 32 away from the crossbeam 1 is fixedly connected to the pressing member 31.

[0048] In order to further improve the coordination effect between the pressing member 31 and the column 2, especially to provide a certain supporting effect on the column 2, the pressing member 31 includes: a vertical plate 311 for supporting the column 2 and a lower plate 312 for pressing and fixing the pressure wall 24. The vertical plate 311 and the lower plate 312 are integrally bent 90 degrees to form a connection hole through the lower plate 312 and the pressure wall 24, and are fixedly connected to the bridge deck to be installed through the connection hole, and the vertical plate 311 and the front wall 21 or the rear wall 22 are closely supported.

[0049] In order to improve the support strength of the support member 32 on the column 2, the support member 32 includes: a U-shaped member 321 for supporting and a support plate 322 for connecting and fixing. In order to ensure the fixed connection strength of the U-shaped member 321, the lower side of the U-shaped member 321 is pressed between the lower plate 312 and the pressure wall 24. In order to ensure the support effect on the column 2, the outer width of the two protruding walls of the U-shaped member 321 is the same as the width of the side wall 23, so the two protruding walls of the U-shaped member 321 and the side wall 23 are flush, and further preferably, the thickness of the protruding wall is the same as the thickness of the side wall 23, so that the stability of the column 2 can be further ensured by the greater strength of the protruding wall to support the side wall 23, and the stability of the side wall 23. The U-shaped member 321 and the outer side of the rear wall 22 are tightly supported, and the support plate 322 and the side wall 23 are fixedly connected. The support plate 322 protrudes from the side wall 23 to the U-shaped member 321 and is fixedly connected between the U-shaped member 321. Therefore, the connection position between the support plate 322 and the U-shaped member 321 can be reasonably arranged to ensure the connection stability.

[0050] In order to ensure the connection strength between the support member 32 and the bridge deck to be installed, the support member 32 further includes: a fixing plate 323, the fixing plate 323 and the lower end of the support plate 322 are integrally formed, the fixing plate 323 and the support plate 322 are bent 90 degrees, and the fixing plate 323 is fixedly connected to the bridge deck to be installed. The fixing plate 323 is bent outward to avoid interference with the pressing member 31.

[0051] In order to ensure the compactness of the entire assembly seat 3, the end of the support plate 322 away from the column 2 is an arc surface, and the side of the U-shaped member 321 away from the column 2 is flush with the end of the support plate 322. The U-shaped member 321 is fixedly connected to the support plate 322.

[0052] In order to ensure the support strength of the column 2, especially for collisions with lower impact force, a greater support effect can be provided. The height of the support plate 322 is higher than the height of the lowest beam 1. Due to the lower impact, the torque is smaller, so the damage to the bridge is smaller, and a larger support fixation can be selected to ensure the safety effect of use.

[0053] In order to improve the supporting effect of the pressing member 31 on the column 2, the supporting effect on the column 2 can be ensured. The pressing member 31 also includes: a side plate 313, which is fixedly connected to the side of the vertical plate 311 and the lower plate 312. One side of the side plate 313 is set close to the column 2, and the side plate 313 and the U-shaped member 321 are fixedly connected.

[0054] In order to achieve the same structure of the pressing member 31 connecting the front wall 21 and the rear wall 22, reduce the types of assembly parts, and reduce the manufacturing cost, the height of the vertical plate 311 is lower than the height of the lowest cross beam 1 to avoid interference with the cross beam 1.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
