Research on No-bracket Construction of Building Structure Reinforcement

This paper studies the no-bracket construction technology for reinforced concrete reinforcement, and uses planting-bar as support to solve problem that scaffolding cannot be erected due site factors. Firstly, steel bar pullout test was carried out study influence of strength, planting diameter, depth, structure type on force planting-bar. Secondly, finite element method used simulate selection formwork parameters under different working conditions. The simulation results were basically consistent with test, which provided appropriate situations a theoretical reference reconstruction expansion project factors such insufficient erection supports.
