Connecting structure for existing buildings and construction method

Abstract

The invention relates to a connecting structure for existing buildings and a construction method and belongs to the technical field of reinforcement and reconstruction. The connecting structure comprises the existing building A, the existing building B, frame columns, outer wrapping steel plates, brackets, main steel beams and sliding rubber supports. The outer wrapping steel plates are arranged on the original frame columns. The outer wrapping steel plates and the frame columns are connected through chemical anchor bolts. The brackets are welded to the steel plates. It should be ensured that the elevations of the upper surfaces of the brackets in each layer are consistent. The additionally arranged main steel beams are seated on the brackets. The main steel beams are joist steel, and the sliding rubber supports serve as joints. According to the connecting structure, the sliding rubber supports are adopted as the connecting joints between two adjacent buildings, and therefore the problem that two buildings with different inherent frequencies and amplitudes are prone to structural damage when receiving an earthquake or other strong vibration after structural connection is solved.

Description

technical field [0001] The invention relates to a connection structure and a construction method between existing buildings, and belongs to the technical field of reinforcement and transformation. Background technique [0002] With the continuous improvement of people's living standards, the continuous innovation of urban and rural construction planning, and the continuous development of production, people will continue to put forward new requirements for the use functions and conditions of various existing production and living houses, so that they can continuously adapt to the development of new situations needs, so there will inevitably be projects to transform existing buildings. [0003] At present, in the process of renovating old houses in our country, it is often encountered that due to development and operation needs, it is necessary to connect two adjacent buildings into one to increase the usable area or to facilitate walking. Especially buildings such as shoppin...

AI Technical Summary

Problems solved by technology

Especially buildings such as shopping malls, hospitals and schools, but considering that the structural forms of two adjacent buildings and newly added connecting parts are different, their natural frequencies and amplitudes are different, and under the influence of temperature, earthquakes or other strong vibrations, the generated The deformation is different, and the two adjacent buildings are prone to structural damage and even collapse events
