Problems solved by technology
Reinforced concrete columns and concrete foundations in existing buildings are integrated vertically. The concrete columns of this structure have poor lateral seismic performance. Once a strong earthquake occurs, the roots of the columns are easily broken under the action of lateral external forces, resulting in the collapse of the building.

Embodiment Construction
[0017] The present invention will be further described below in conjunction with drawings and embodiments.
[0018] This embodiment is a reinforced concrete column in a building, such as figure 1 with figure 2 As shown, the cross-section of the concrete column 1 is 400mm╳400mm square, the height of the concrete column is 3600mm, and it is integrated with the concrete foundation 6.
[0019] The construction method of the reinforced concrete column comprises the following steps:
[0020] 1. Processing and making cylindrical steel block 3, basic steel block 5 and v-shaped steel bar 4
[0021] The front of the column steel block 3 is 200mm╳200mm square, and the thickness is 50mm. On the two sides opposite to the thickness direction, three reserved holes are drilled at a distance of 40mm from one end face. The reserved holes are through holes. The mutual distance is 60mm;
[0022] The shape and size of the basic steel block 5 are the same as that of the cylindrical steel block...

The invention discloses a reinforced concrete column. Two sides of the lower part of the concrete column body are respectively provided with column body steel blocks integrally welded with reinforcement cages of the concrete column body, foundation steel blocks corresponding to the column body steel blocks and integrally welded with the reinforcement cages of concrete foundation reinforcement cages are arranged at the upper part of the concrete foundation; and two side surfaces of parts, exposed out of the concrete column body, of the column body steel blocks and two side surfaces of the part, exposed out of the concrete foundation, of the foundation steel blocks are connected into a whole by welding V-shaped reinforcing steel bars into preformed holes. As two groups of V-shaped reinforcing steel bars in fixed connection with the concrete foundation are added at the two sides of the root of the concrete column body, the reinforced concrete column has the anti-seismic property, when suffering from powerfully lateral external force resulted from earthquake, even if the concrete column body inclines, only the V-shaped reinforcing steel bars deform, and the earthquake energy is consumed by the deformed V-shaped reinforcing steel bars, so the concrete column body is not easy to break from the concrete foundation, the building is not easy to collapse, and the anti-seismic property is improved.
Description
technical field [0001] The invention relates to a building structure, in particular to a reinforced concrete column with anti-seismic performance and a construction method thereof. Background technique [0002] Reinforced concrete columns are architecturally important components that play an important role in the strength of buildings. Reinforced concrete columns and concrete foundations in existing buildings are integrated vertically. The concrete columns of this structure have poor lateral seismic performance. Once a strong earthquake occurs, the roots of the columns are easily broken under the action of lateral external force, resulting in the collapse of the building. Contents of the invention [0003] The object of the present invention is to provide a reinforced concrete column with anti-seismic performance and its construction method for the above-mentioned defects of the existing reinforced concrete column, so as to reduce the damage to the building caused by the e...
