Joint reinforcement structure for existing buildings and construction method

Abstract

The invention provides a joint reinforcement structure for existing buildings and a construction method. The construction method comprises the steps that the outer side wall of a middle supporting body of an existing structure and the inner side wall of the side wall are roughened to form concave-convex faces, and a plurality of vertical steel bars are laid; the upper surface of a bottom plate andthe lower surface of the a top plate are roughened, a plurality of transverse steel bars are laid, and the vertical steel bars and the transverse steel bars are connected and fixed to main steel barsin the bottom plate and the top plate; the outer side faces of a bottom beam and a top beam are roughened; the outer side wall of the middle supporting body, the inner side wall of the side wall, theupper surface of the bottom plate, the lower surface of the top plate, and the outer side faces of the bottom beam and the top beam are subjected to thickening pouring to form poured layers; and theupper surface of the top plate is roughened, transverse steel bars are laid, thickening pouring is conducted, and a rail traffic structure foundation is formed. Under the situation that certain important building structures cannot be avoided by rail traffic, joint reinforcement transformation is conducted on the existing building structure, thus passing can be achieved in a rail traffic zone, andmeanwhile the existing building structure is not dismantled.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a combined reinforcement structure for existing buildings and a construction method. Background technique [0002] Rail transit has become an effective way to relieve urban traffic congestion due to its advantages of large capacity, safety and comfort, and low transportation cost. With the development of the city, there are inevitably existing structures on the rail transit route. However, the price of urban land is becoming increasingly expensive, and some buildings and structures have relatively important functions, so it is very difficult to requisition and demolish them. In the case of rail transit overpassing existing structures, a part of it can be reserved as the track foundation of rail transit as appropriate. At this time, it needs to be reinforced and reconstructed to meet the requirements of rail transit. [0003] When the rail transit route cannot avoid the exis...

AI Technical Summary

Problems solved by technology

If you choose the in-situ combined reconstruction scheme, the time period will be longer, and the relevant needs cannot be met before the reconstruction is completed

The reliability and redundancy of a single reinforcement scheme for existing buildings and structures are insufficient, and cannot meet the characteristics of heavy load and vibration of rail transit
