Description

Guardrail reinforcing steel bar protection layer positioning die carrier Technical Field The utility model belongs to the technical field of reinforced concrete structure construction, and particularly relates to a positioning formwork for a guardrail reinforcement protection layer. Background The bridge deck guardrail is a key component of bridge engineering and plays an important role in ensuring driving safety and maintaining the stability of the whole structure of the bridge, so that the construction quality of the bridge deck guardrail is important. The thickness of the protective layer of the guardrail reinforcing steel bar is one of important indexes for measuring the quality of the guardrail, and the verticality of the reinforcing steel bar inside the guardrail and the distance between the reinforcing steel bars are core factors for ensuring that the thickness of the protective layer of the reinforcing steel bar meets design requirements. In the traditional bridge deck guardrail steel bar binding construction process, the control of the steel bar verticality and the steel bar spacing mainly depends on constructors experience and simple tools, such as visual inspection, line weight and steel rule adjustment. However, the positioning mode is difficult to guarantee in precision, low in construction efficiency and easy to be influenced by capability differences of constructors and subjective factors. In the actual construction process, the problems of overlarge deviation of the verticality of the steel bars, uneven spacing of the steel bars and the like are easy to occur, and the uniformity of the thickness of the steel bar protection layer is directly affected, so that the protection performance and the structural stability of the guardrail are reduced.
