Wall reinforcing structure and method for improving integrality of historic buildings

Abstract

The invention discloses a wall reinforcing structure and method for improving the integrality of historic buildings. According to the wall reinforcing structure and method, the characteristics that most historic buildings are of brick concrete structures, no ring beam is used, and dead loads are large are considered, walls are reinforced through the reinforcing scheme based on offsite component prefabricating and site assembling, and the historic buildings are prevented from being continuously collapsed by vibration. By means of the wall reinforcing structure and method, the structure integrality can be improved, when vibration loads are externally and suddenly exerted, deformation of the walls is effectively controlled, and continuous collapse caused by overall instability of the historic buildings is prevented. Meanwhile, the wall reinforcing structure and method have the advantages of being high in reversible degree, free of working with naked fire in a site, easy to operate, convenient to apply, free of damage to historic building bodies and the like, the effective protection effect can be achieved when the historic buildings and particularly key cultural relics distributed in urban areas with dense buildings are influenced by construction technologies, with vibration characteristics, of municipal administration dismantling projects, metro building blasting projects, metro building deep foundation pit excavation projects, metro building large-diameter pile foundation construction and the like, and the wall reinforcing structure and method have the wide application prospects in the aspect of preventing extreme damage conditions, such as continuous collapse, of the historic buildings.

Description

[0001] technical field [0002] The invention belongs to the technical field of building reinforcement, and relates to a wall reinforcement structure and method for strengthening the integrity of ancient buildings. [0003] Background technique [0004] With the development of the times, urban construction is getting faster and faster, large-scale buildings, tunnels and other projects can be seen everywhere, and many projects are adjacent to ancient buildings. Since ancient buildings are mostly brick-concrete structures or wood component systems, they cannot form a complete frame system, lack seismic ring beams and structural column components, and have the characteristics of self-heavy, poor integrity, and low natural frequency, so they are very sensitive to vibration. Surrounding large-scale engineering construction, especially municipal engineering, blasting engineering for subway construction, deep foundation pit excavation engineering, and large-diameter pile foundatio...

Problems solved by technology

Vibration during this process may lead to continuous collapse and damage of the above-mentioned ancient buildings, resulting in irreversible consequences

Due to the long service life, long-term alternation of cold and heat, rain immersion, air oxidation, earthquake and some man-made damage, the walls of ancient buildings are aging, the bearing capacity is greatly reduced, and the structural integrity is poor. The damage of a piece of wall is likely to cause the continuous collapse of the whole structure
