Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, and in particular to an efficiently installed bridge guardrail. Background Art

[0002] Guardrails are very common isolation and protection devices on roads and bridges. They are usually composed of columns and crossbars, which can be assembled and erected on the road surface during installation.

[0003] Different from the common highway guardrails, the installation of bridge guardrails is completely fixed, that is, the columns are completely fixed to the bridge deck through bolts and other structures, while most of the guardrails on highways simply place the columns (usually concrete piers with a certain weight) on the ground, which mainly play a role of isolation, while the guardrails on bridges mainly play a protective role, so the guardrails on bridges need to be completely fixed.

[0004] The guardrail on the bridge is also composed of columns and crossbars. When installing, the columns are first fixed to the ground by bolts, and then the crossbars are fixed through the holes on the columns. However, it is cumbersome to punch holes. If the hole diameter is too large, the column will be unstable and easy to loosen. If the hole diameter is too small, it will be difficult to pass through. In addition, multiple crossbars will pass through a column, and there will be a column every few meters, so it will take a lot of time to install. Therefore, a guardrail that can be installed faster and more efficiently can be designed. Utility Model Content

[0005] The utility model aims to provide a bridge guardrail that can be installed efficiently, which eliminates the need for punching operations and makes installation faster and more efficient.

[0007] Furthermore, the opening of the first mounting groove is oriented obliquely upward; and the opening of the second mounting groove is oriented obliquely downward.

[0008] Furthermore, the connecting member includes a first connecting hole opened in the bottom plate, a connecting plate arranged at the lower end of the second vertical plate, a second connecting hole opened in the connecting plate, and a first bolt passing through both the first connecting hole and the second connecting hole.

[0009] Furthermore, the connecting member also includes a third connecting hole opened at the upper end of the first vertical plate, a fourth connecting hole opened at the upper end of the second vertical plate, and a second bolt passing through both the third connecting hole and the fourth connecting hole.

[0010] Furthermore, upper ends of the first vertical plate and the second vertical plate are both arc-shaped surfaces.

[0011] Furthermore, a groove is formed on a side of the first vertical plate close to the second vertical plate.

[0012] Furthermore, a through hole is formed in the middle of one side of the second vertical plate close to the first vertical plate.

[0013] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects: the efficiently installed bridge guardrail of the utility model is to first install the base plate on the ground during installation, and then directly put the cross bar in the first installation groove on the first vertical plate, and then stick the second vertical plate on the first vertical plate, and make the second installation groove buckle on the cross bar, and then use the connecting piece to connect the first vertical plate and the second vertical plate, so that there is no need for tedious punching operations when installing the cross bar, and the installation speed is faster and more efficient; and the first installation groove and the second installation groove can tightly clamp the cross bar to prevent it from rotating or axial movement, etc., the overall stability of the guardrail is higher, and the single first vertical plate and the second vertical plate can be removed without affecting the cross bar and other structures, so as to facilitate maintenance, replacement and other operations.
