Reinforced concrete beams and columns

Abstract

This invention provides a reinforced concrete beam and column reinforcement structure, which includes: an inner layer of reinforcing bars, an outer layer of frame, and a plurality of fixed connectors; the construction method includes: a prefabrication step, an assembly step, a sealing step, and a grouting step; through the structural design of the inner layer of reinforcing bars, the outer layer of frame, and the plurality of fixed connectors, the reinforcement structure can be prefabricated and only needs to be assembled on site. In addition to reducing the amount of on-site cutting and adjustment work, improving safety and reducing manpower requirements, it can also shorten the construction period of reinforced concrete beams and columns.

Claims

A reinforced concrete beam-column reinforcement structure, comprising: an inner layer of reinforcing bars; an outer frame assembly surrounding the inner layer of reinforcing bars and having a plurality of steel bars arranged along a first direction and forming a ring, and a plurality of external connectors arranged along a second direction and connecting the steel bars; and a plurality of fixed members fixed to the inner layer of reinforcing bars and the outer frame assembly.

2. The reinforced concrete beam-column reinforcement structure as described in claim 1, wherein, The inner reinforcement group has a plurality of steel bars arranged along the first direction and forming a ring, and a plurality of inner connectors arranged along the second direction and connecting each steel bar.

3. The reinforced concrete beam-column reinforcement structure as described in claim 2, wherein, The inner connectors form a plurality of rings, and the outer connectors form a plurality of rings.

4. The reinforced concrete beam-column reinforcement structure as described in claim 3, wherein, The plurality of the fixed members are fixed to the steel bars and / or inner connectors of the inner layer steel reinforcement group and the steel bars and / or outer connectors of the outer frame group.

5. The reinforced concrete beam-column reinforcement structure as described in claim 1, wherein, The inner layer of reinforcing bars is made of H-beams.

6. The reinforced concrete beam-column reinforcement structure as described in claim 5, wherein, The plurality of the fixed members are fixed to the H-beams of the inner reinforcing steel group and the steel bars and / or external connecting members of the outer frame group.
