Reinforcement structure and reinforcement method for column removal of top layer of building structure

Abstract

The invention discloses a reinforcement structure and a reinforcement method for column removal of a top layer of a building structure. The reinforcement structure for column removal of the top layer of the building structure comprises a column to be removed, first and second adjacent reserved column bodies symmetrically arranged on the two sides of the column to be removed, a reserved beam body erected on the upper parts of the column to be removed and the adjacent reserved column bodies and a roof panel, wherein a reconstruction underpinning beam is arranged on the upper part of the reserved beam body along the longitudinal direction of the reserved beam body, and is connected with the reserved beam body through chemically-bonded rebar; the roof panel, the reconstruction underpinning beam and the reserved beam body are fixedly connected through a connecting mechanism; a reaction beam is arranged on the upper part of the reconstruction underpinning beam, and multiple jacks are arranged at equal intervals at the bottom of the reaction beam along the longitudinal direction of the reaction beam. The reinforcement structure and the reinforcement method have the advantages of convenience for construction and calculation, small construction quantity, capability of saving construction time, small influence on the normal using condition of a building, high stress performance and the like.

Description

technical field [0001] The invention relates to the technical field of reinforcement and underpinning of building structures, in particular to a reinforcement structure for extracting columns on the top floor of building structures. In addition, the invention also relates to a method for strengthening the top-floor extraction column of the building structure. Background technique [0002] In the process of some architectural design and use, there are often some situations that cannot meet the use of architectural space, and some columns need to be extracted to meet the needs of the use of space. However, when the column extraction is carried out, the balance state of the building structure system is destroyed. First, the beam supported on the column loses the support of the column, and the span increases, and the mechanical performance of the structure undergoes new changes, which makes the beam The deflection, cracks, bearing capacity, etc. of the column do not meet the de...

Problems solved by technology

[0004] The invention provides a reinforcement structure and a reinforcement method for drawing columns on the top floor of a building structure, to solve the problem that most of the construction process of the existing building structure renovation measures is carried out indoors, and the normal use of the floors below the drawing column layer will cause relatively large If necessary, it is necessary to strengthen the foundation of the relevant columns, which has the problems of complex construction, large amount of engineering, and high construction difficulty
