Integrated-tray, shock-insulation and reinforcing structure for historic building foundation and construction method thereof

Abstract

The invention relates to an integrated-tray, shock-insulation and reinforcing structure for a historic building foundation and a construction method thereof. The integrated-tray, shock-insulation and reinforcing structure comprises static pressure piles, oriented drilling steel tube concrete beams and shock-insulation pads. The static pressure piles are arranged on the outer side of the existing historic building, the bottom of a foundation horizontally penetrates through the oriented drilling steel tube concrete beams, the shock-insulation pads are arranged between the piles and the beams, and accordingly novel n-shaped shock-insulation foundation frames for the existing building is formed. In the longitudinal direction, the plurality of n-shaped shock-insulation foundation frameworks are integrally connected through connecting beams to form a shock-insulation foundation system of the whole building. In order to guaranteed connection between the steel tube concrete beams and an upper portion original foundation, necessary anchor rods are utilized to pull and knot. The steel tube beams can bear all vertical load of the original building and all load of indoor soil and structures above the bottom of the foundation. Gaps between the steel tube concrete beams are filled up with oriented drilling rear plain concrete to form an integrated supporting platform. The steel tube beams are supported by the piles at two ends through the shock-insulation pads. In earthquake, the shock-insulation pads can greatly reduce various effects of earthquake force on the upper portion buildings.

Description

technical field [0001] The invention relates to an ancient building foundation integrated pallet seismic isolation reinforcement structure and a construction method thereof, in particular to a foundation isolation system composed of piles, steel pipe beams and isolation pads, belonging to the technical field of seismic reinforcement. Background technique [0002] Earthquake prevention and disaster reduction during China's 12th Five-Year Plan period is an important task of the government. Frequent earthquakes in recent years have caused huge damage to ancient buildings that have been around for hundreds or even thousands of years. Take the 8.0-magnitude Wenchuan earthquake in 2008 as an example. According to incomplete statistics, according to preliminary statistics In Sichuan Province alone, 83 national key cultural relics protection units and 174 provincial-level cultural relics protection units suffered varying degrees of damage, causing huge social losses, and their econom...

[0002] Earthquake prevention and disaster reduction during China's 12th Five-Year Plan period is an important task of the government. Frequent earthquakes in recent years have caused huge damage to ancient buildings that have been around for hundreds or even thousands of years. Take the 8.0-magnitude Wenchuan earthquake in 2008 as an example. According to incomplete statistics, according to preliminary statistics In Sichuan province alone, 83 national key cultural relics protection units and 174 provincial-level cultural relics protection units have suffered damage to varying degrees, causing huge social losses, and the economic losses are incalculable

Traditional ancient building repair and reinforcement focuses on partial replacement of upper rods and renovation of finishes, but the impact of moderate and above-level earthquakes cannot be reduced. Traditional building reinforcement technologies such as slab wall reinforcement, ring beam structural column reinforcement, and carbon fiber reinforcement require indoor construction. , First, it will destroy the original indoor decoration that cannot be recreated, second, the interior space cannot be used for construction operations, third, it may destroy the complete shape, and fourth, there may be religious taboos

In addition, traditional reinforcement is hard resistance, and the limitations of indoor reinforcement are too large
