Tensile bonded rebar structure

Abstract

The invention relates to the technical field of construction engineering, in particular to a tensile bonded rebar structure for connecting an original concrete column with an additionally arranged beam. The tensile bonded rebar structure is applied through a splay connection steel plate, a rebar bolted or welded to a web of the connection steel plate and a carbon fiber sheet wrapped on the periphery of the original concrete column and connected with the splay connection steel plate, thus, the quantity and the area of rebars needing to be planted on the original concrete column can be greatly decreased, the number of holes drilled in the original concrete column is decreased, damage to the original concrete column is reduced, a reinforcement effect on the original concrete column is achieved, and the bearing capacity of the original concrete column is greatly improved; and in addition, a part of tension of the additionally arranged beam to the bonded rebar interface is converted into lateral pressure to the original concrete column through the carbon fiber sheet, not only is the tension of the additionally arranged beam to the bonded rebar interface decreased, but also a three-directional pressure state of the original concrete column is formed, the reinforcement effect on the original concrete column is achieved, and the bearing capacity of the original concrete column is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a tensile reinforcement planting structure. Background technique [0002] With the development of society, the area of ​​new domestic buildings begins to peak, and the reinforcement and transformation of existing buildings will become the main business of the construction industry. In the process of reinforcement and transformation, the technology of planting reinforcement and adding layers is often used to change the use of buildings. Functional requirements. In the process of planting reinforcement and adding layers, it is necessary to drill holes on the column, which causes some damage to the column, and the new layer makes the column need to bear extra weight. The tensile effect of the planting bar interface is an important key to the success of the bar planting. Therefore, a new type of technology is needed to reduce the number and area of ​​rebars, reduce...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems in the prior art that there are too many bars planted on the surface of the column, the column is damaged greatly, the bearing capacity is insufficient, and the tensile capacity of the planted bar interface is insufficient, and a tensile planted bar structure is provided.
