Reinforcing reinforced concrete column and construction method thereof

Abstract

The invention provides a reinforcing reinforced concrete column and a construction method thereof. The reinforcing reinforced concrete column includes a reinforced concrete column body, two prefabricating fiber reinforced concrete duct pieces and a plurality of fiber cloth layers; the two prefabricating fiber reinforced concrete duct pieces are embraced together around the periphery of the reinforced concrete column body and the two prefabricating fiber reinforced concrete duct pieces and the reinforced concrete column body are fixedly connected by a plurality of penetrating bolts; the fiber cloth layers are tightly arranged on the outer surfaces of the two prefabricating fiber reinforced concrete duct pieces in a surrounding mode; and the rest of fiber cloth layers are successively surrounded on the periphery of the fiber cloth layers and the fiber cloth layers are connected in an adhesive mode by adhesives. The construction method includes the following steps of manufacturing the prefabricating fiber reinforced concrete duct pieces, drilling bol holes, chiseling grooves, injecting glue, planting bars, mounting the prefabricating fiber reinforced concrete duct pieces and twining cloth. According to the reinforcing reinforced concrete column and the construction method thereof, the construction period is short, bearing capacity, rigidity and ductility deformability of the reinforced concrete column can be effectively improved, and the reinforcing column has the rigidity and the ductility at the same time.

Description

technical field [0001] The invention specifically relates to a reinforced concrete column and a construction method thereof. Background technique [0002] Structural columns in bridges, multi-storey and high-rise buildings are the most basic and important load-bearing components of structures. The combination of axial force, bending moment and base shear force makes the structural column more vulnerable to damage, and once it fails, it will directly lead to the overall collapse of the structure. A large number of industrial and civil buildings, with the development of economy and technology, need to improve their original design level, change their use function, or increase the constant live load in reinforcement and reconstruction projects. Specifications require reinforcement. In addition, due to construction quality problems, deterioration of the use environment, material aging, natural disasters and sudden accidents, a large number of early reinforced concrete columns ...

AI Technical Summary

Problems solved by technology

[0003] Enlarging section method is one of the most important methods to improve the bearing capacity of reinforced concrete columns. This method is easy to obtain materials, simple construction technology and reliable effect. It is widely used in the reinforcement of structures. There are many operations, which have a great impact on the surrounding environment, and the increase in stiffness after reinforcement increases the seismic force distributed, resulting in a decrease in its ductile deformation capacity, which is not conducive to earthquake resistance
