Description

CFT column reinforcement structure {CFT COLUMN REINFORCEMENT STRUCTURE}

The present invention relates to a CFT column reinforcement structure, wherein concrete is filled in an interior space to configure a reinforcement structure according to bending resistance, and a joint area is variably configured according to the bending resistance of a beam installed horizontally from a vertical column structure. , It relates to a CFT column reinforcement structure having a multifaceted area and a reinforcing structure so as to be able to respond to the stress applied by constructing a reinforcing structure according to the bending resistance inside.

Conventionally, in order to construct a structure, a vertical structure of H-beam was constructed, a horizontal structure installed horizontally from the vertical structure was joined to each other, and a floor plate and a roof were installed to construct a steel structure.

As the height of the steel structure increases and the size of the structure increases, the size and thickness of the H-beam used as a vertical structure and a horizontal structure must be increased together, so that the self-weight of the steel structure is also increased.

In addition, as the stress increases with the increase of the self-weight, there is a problem in that the cost increases and the length of time according to the additional work increases as a reinforcing structure must be additionally configured at the point where the concentrated stress acts on each steel structure.

Therefore, in place of the conventional H-beam, recently, a hollow structure is used, and a structure of a concrete filled steel (CFT) column is used to fill concrete inside when the installation is completed.

However, conventional CFT pillars are constructed to have a ㅁ, ㅇ, and ㅍ-shaped structure by bending steel plates and welding them to each other. However, since the interior is made of hollow, the horizontal structure connected horizontally to the CFT column There is still a problem in that a bending phenomenon occurs in the CFT column due to the resulting external stress.

Accordingly, there is a need for a new structured CFT column reinforcement structure having an internal reinforcement structure to be able to resist the bending phenomenon caused by the horizontal structure joined to the CFT column.
