Description

Technical Field

[0001] This utility model relates to the field of column assembly tooling technology, and in particular to a steel guardrail column assembly tooling. Background Technology

[0002] With economic development, more and more highways require the construction of bridges. During the construction of bridges and roads, it is often necessary to build crash barriers to ensure the safety of vehicles traveling on bridges and roads. Therefore, the construction of crash barriers has become an important task in the construction process. Because common crash barriers require irregularly shaped steel guardrail posts to facilitate the installation of the rear guardrail railings, steel guardrail posts composed of curved parts, web plates, front plates, and base plates form a spatial frame structure. This not only makes it easier to install the railings but also provides high structural strength and an aesthetically pleasing appearance.

[0003] Steel guardrail posts require the assembly of various components first, followed by spot welding of key connections to facilitate the overall structural welding and ensure structural strength. However, irregular shapes increase processing difficulty, and positioning, assembly, and pre-welding of the guardrail components become challenging during assembly. Therefore, a steel guardrail post assembly fixture needs to be designed. Utility Model Content

The several post fixing limiting structures are spaced apart. The steel guardrail posts are placed on the post base plate limiting structure and the several post fixing limiting structures for positioning and assembly.

[0007] Furthermore, the steel guardrail post includes a base plate, a web plate, a back plate, stiffening ribs, wing plates, and angle steel beams.

The wing plate fixing plate is arranged horizontally, the transverse limiting plate and the side limiting structure are arranged on both sides of the wing plate fixing plate, and the web plate support plate is arranged at the front end of the wing plate fixing plate. The height of the web plate support plate is higher than that of the wing plate fixing plate.

[0010] Furthermore, pre-tightening bolts are provided on the transverse limiting plate, and the pre-tightening bolts are tightened laterally to compress and fix the column back plate.

[0011] Furthermore, the side limiting structure includes a pad limiting plate and an angle steel limiting plate. The pad limiting plate is arranged opposite to the transverse limiting plate, and the angle steel limiting plate is arranged on the side of the pad limiting plate.
