Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for the positioning of guardrail construction, and particularly relates to a positioning device for the facing panel of an anti-collision guardrail. Background Technique

[0002] On both sides of some expressways or ordinary roads, various guardrails are installed. One of the common guardrails is a concrete anti-collision guardrail, whose main structure is made of concrete and processed with strong and reliable steel products. The concrete anti-collision guardrail is a guardrail cast from reinforced concrete. The anti-collision guardrail is generally used on expressways or highway bridges, which is relatively strong and reliable, and can avoid being damaged by impact. When a vehicle has an accident and hits the anti-collision guardrail, it will not break through the anti-collision guardrail and fall below the road surface or bridge deck, causing greater losses and casualties.

[0003] When manufacturing the anti-collision guardrail on a bridge, generally, steel bars are implanted in the bridge concrete layer, and the steel bars are welded to form a steel bar support. Then, templates are installed on both sides of the steel bars, and finally, concrete is poured from the top of the steel bar support to manufacture the anti-collision guardrail base. Finally, the steel railing is installed on the anti-collision guardrail base. In the above operations, the bottom thickness of the anti-collision guardrail base connected to the concrete layer is required to be greater than the upper thickness. Therefore, a bent template is needed. During the pouring process, the bottom end of the bent template is unstable under the action of the poured concrete, which is likely to cause the top end of the template to be skewed, which is not conducive to accurate installation and realizing the positioning of the poured concrete. When the concrete is poured outside the steel bars to form the anti-collision guardrail base, there is a problem that there is no design that can accurately and stably install and position the poured concrete. For this reason, the present application proposes a positioning device for the facing panel of an anti-collision guardrail. Content of the Utility Model
