Reinforced concrete column welding ring rib reinforced structure and construction method thereof

Abstract

The invention discloses a reinforced concrete column welding ring rib reinforced structure. A reinforced cage is arranged on the side face of the bottom of a to-be-reinforced reinforced concrete column, the height of the reinforced cage is equal to the length of a column bottom plastic hinge area of the to-be-reinforced reinforced concrete column, the reinforced cage comprises more than one vertical longitudinal ribs and more than one welding ring ribs, the vertical longitudinal ribs are located inside the welding ring ribs, the welding ring ribs are fixedly connected with the vertical longitudinal ribs, and a concrete layer covering the reinforced cage is poured on the side face of the bottom of the to-be-reinforced reinforced concrete column. The invention also discloses a construction method of the reinforced concrete column welding ring rib reinforced structure. The reinforced concrete column welding ring rib reinforced structure is used for realizing small construction workload and simple construction process, aiming to the phenomenon that the column end of the reinforced concrete column is damaged in the earthquake, the weak column bottom is reinforced, and part of the reinforced concrete column is reinforced to achieve anti-seismic reinforcement of the whole column.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a reinforced concrete column welded ring reinforcement structure and a construction method thereof. Background technique [0002] Buildings often need to strengthen their structures due to changes in building functions, building aging, natural disasters or human factors. At the current stage, in addition to meeting the requirements of bearing capacity, structural reinforcement must also consider the seismic requirements, so that the reinforced structure can meet the corresponding seismic requirements. my country's anti-seismic fortification standards can be summarized as "small earthquakes are not damaged, moderate earthquakes can be repaired, and large earthquakes do not collapse." When a building does not meet the requirements of the current design codes and cannot meet the current anti-seismic fortification standards, it is necessary to carry out targeted structura...

AI Technical Summary

Problems solved by technology

However, when using these reinforcement methods to strengthen reinforced concrete columns, there are problems such as complicated construction procedures, slow construction speed, and how to ensure that the reinforcement materials have sufficient durability.

For example, using enlarged cross-sections to strengthen reinforced concrete columns will lead to heavy wet work workload on the construction site and a long construction period. In addition, the increase in the size of the column components may affect its use function and the mechanical performance of other components; the use of pasted reinforcement materials To strengthen reinforced concrete columns, it is necessary to consider the durability of the reinforcement material and the adhesion between the reinforcement material and the surface of the column. It is necessary to carry out fire and anticorrosion treatment on the reinforcement material and organic glue to increase the service life of the material.
