Description

Technical Field

[0051] like Figure 1-Figure 6As shown, the pluggable column bridge guardrail includes: a column member 01 for supporting and fixing and a cross beam member 02 for anti-collision connection, and the side of the column member 01 is fixedly connected to the cross beam member 02.

[0052] In order to facilitate the connection between the column member 01 and the bridge deck, the column member 01 includes: a column body 1 that is connected to the e-level cross beam member 02, and a plug-in socket 2 that is fixedly connected to the bridge deck. A plug-in hole is reserved in the center of the plug-in socket 2, and the lower end of the column body 1 is inserted into the plug-in hole. The column body 1 and the plug-in socket 2 are fixed by multiple bolts to ensure the connection strength. The plug-in connection method facilitates the assembly between the column member 01 and the bridge deck. It improves the construction efficiency and ensures the installation strength and stability after construction.

[0053] In order to facilitate the connection between the plug socket 2 and the column body 1, the stability of the plug socket 2 itself can be improved, thereby ensuring the strength of the entire guardrail. The plug socket 2 includes: a central tube 21 for limiting the connection with the column body 1, a support tube 22 and a support rib 23 for supporting and fixing the central tube 21. The central tube 21 is provided with a plug-in hole, the outer wall of the central tube 21 is fixedly connected to the support tube 22, and the outer wall of the support tube 22 is fixedly connected to the support rib 23.

The support rib 23 and the support tube 22 are integrally connected to ensure the connection strength and the support effect on the support tube 22.

[0057] It also includes: a fixing plate 03 that is fixedly connected to the bridge deck and ensures the connection and fixing of the plug socket 2. The lower ends of the central tube 21, the support tube 22 and the support rib plate 23 are fixedly connected to the upper surface of the fixing plate 03, and the fixing plate 03 is fixedly connected to the bridge deck to be connected.

[0058] In order to achieve the height adjustment of the column body 1, the plug-in structure can meet different construction requirements in a more diverse manner, especially for special temporary construction processes, where the height of the guardrail needs to meet a certain height. After the construction is completed, it is necessary to restore the original structure. The column body 1 includes: an outer column 11 connected to the cross beam 02, an extension tube 12 and an extension column 13 for extending the support height. The center of the outer column 11 is connected to the extension tube 12, and the center of the extension tube 12 is connected to the extension column 13; the extension tube 12 and the extension column 13 can extend to a set height, so that the entire column body 1 can support different heights, thereby meeting the support of different heights of the cross beam 02, which is convenient for meeting construction requirements.

[0059] A plurality of connection holes 14 are provided through the outer column 11, the extension tube 12 and the extension column 13, and bolts are passed through the connection holes 14 to fix them. When the extension tube 12 and the extension column 13 are extended along the outer column 11, a plurality of connection holes 14 can be aligned at each extended position, so that a bolt can be inserted into each connection hole to ensure the connection strength of the outer column 11, the extension tube 12 and the extension column 13.

[0060] The side of the outer column 11 is fixedly connected to the cross beam 02 .

[0061] In order to ensure the extension effect of the outer column 11, the extension tube 12 and the extension column 13, it is ensured that during the extension process, the extension tube 12 and the extension column 13 are extended together first, and the extension column 13 is extended last. The connection area between the fixed plate 03 is ensured to be the largest, and the support strength of the column body 1 is improved. The column body 1 also includes: an extension component 15 for limiting the extension effect, and the inner wall of the outer column 11, the upper end of the extension tube 12 and the upper end of the extension column 13 are slidably connected through the extension component 15.

[0062] In order to reasonably limit the extension effect of the outer column 11, the extension tube 12 and the extension column 13. The extension component 15 includes: an upper extension component 151 that mainly limits the extension tube 12 and a lower extension component 152 that mainly limits the extension column 13. The lower end of the upper extension component 151 is fixedly connected to the upper end of the extension tube 12, the upper extension component 151 is limitedly connected to the inner wall of the outer column 11, the lower end of the lower extension component 152 is fixedly connected to the upper end of the extension column 13, and the upper end of the lower extension component 152 is limitedly connected to the upper end of the extension tube 12.

[0063] In order to achieve the cooperation with the inner wall of the outer column 11, and the cooperation connection with the extension tube 12, the upper extension assembly 151 includes: an upper limit plate 3 and an upper connecting column 4, the lower end of the upper limit plate 3 is fixedly connected to the upper connecting column 4, the lower end of the upper connecting column 3 is fixedly connected to the upper end of the extension tube 12, and a limiting boss 5 is arranged at the cavity position of the upper connecting column 4 and the inner wall of the outer column 11; through the limiting action between the limiting boss 5 and the upper limit plate 3, the outer column 11 can be pulled up to a set height to drive the extension tube 12.

[0064] In order to further prevent the outer column 11 and the extension tube 12 from rotating relative to each other, thereby affecting the alignment of the connection holes and causing inconvenience in the installation and connection of the bolts, the end surface of the limiting boss 5 close to the upper connection column 4 is in an arc shape, and the limiting boss 5 is sleeved on the outer wall of the upper connection column 4. The arc-shaped structure limits the relative rotation of the outer column 11 and the extension tube 12, ensuring that multiple bolts can be installed smoothly after extension.

[0065] In order to achieve the cooperation with the end of the extension tube 12, it can also be connected with the extension column 13. The lower extension component 152 includes: a lower limit plate 6 and a lower connecting column 7. The lower end of the lower limit plate 6 is fixedly connected to the lower connecting column 7. The lower end of the lower connecting column 7 is fixedly connected to the upper end of the extension column 13. The outer diameter of the lower limit plate 6 is larger than the inner diameter of the extension tube 12 (the lower extension component 152 can be driven to slide by the extension tube 12, thereby driving the extension column 13), and the outer wall of the lower limit plate 6 is provided with a notch, and the side of the upper connecting column 4 close to the lower limit plate 6 extends into the notch for limiting. The notch structure limits the relative rotation of the extension tube 12 and the extension column 13, further ensuring the normal position of the connecting hole 14, thereby ensuring the connection.

[0066] In order to improve the anti-collision effect of the guardrail, the crossbeam 02 includes: a D-shaped crossbeam 8, a corrugated plate 9 and a connecting block 10. The D-shaped crossbeam 8 is fixedly connected to the side of the outer column 11 near the upper end, and the side of the outer column 11 near the lower end is fixedly connected to the corrugated plate 9 through the connecting block 10.

[0067] 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.
