Problems solved by technology

[0006] There is no doubt about the advancement of flexible seismic isolation theory and the excellent effect of flexible seismic isolation technology, but at present this advanced theory and technology can only be used in new buildings, how to apply this advanced theory and technology to a large number of Existing buildings, especially important buildings that need to get rid of the threat of strong earthquakes as soon as possible, such as: multi-storey brick-concrete structure residences and a large number of rural residential buildings, schools, kindergartens, hospitals, office buildings, ancient buildings, etc. unprecedented

Embodiment 1

[0017] Embodiment 1: see figure 1 , figure 2 . Determine the position and height of the flexible shock-isolation layer of the seismic-isolation reconstruction building; select the commercial rubber bearing (16) as the shock-isolation layer. The indoor and outdoor floors (13, 14) of the seismically isolated reconstruction building are excavated offline to the top of the original foundation (12). The connection beam (9) hole of the sliding beam is excavated on the wall body (11) of the building for seismic isolation reconstruction, and reinforced concrete is poured. The two sides of the original foundation (12) of the earthquake-isolation reformed building expand the foundation, and the reinforced concrete sliding beam (2) is poured on the enlarged foundation to the lower plane of the flexible earthquake-isolation layer. Rubber bearings (16) are set above the lower beam (2). The connection beam (8) hole of the upper sliding beam (1) is excavated on the wall body (11) of the...

Embodiment 2

[0018] Example 2: see image 3 , Figure 4. Determine the position and height of the flexible seismic-isolation layer of the seismically-retrofitted building; select the slip surface (3, 4, 5) as the flexible seismic-isolation layer. The indoor and outdoor floors (13, 15) of the building for earthquake-isolation reconstruction are excavated offline to the top of the original foundation (12). The connection beam (9) hole of the sliding beam is excavated on the wall body (11) of the building for seismic isolation reconstruction, and reinforced concrete is poured. The two sides of the original foundation (12) of the earthquake-isolation reformed building expand the foundation, and the reinforced concrete sliding beam (2) is poured on the enlarged foundation to the lower plane of the flexible earthquake-isolation layer. Considering the maximum slip of the seismically isolated retrofitted building during the highest level of earthquake, the two sides of the glide beam (2) are re...

Embodiment 3

[0019] Embodiment 3: see figure 1 , figure 2 . When the translational design of the building is carried out, the seismic isolation reconstruction design is carried out at the same time. Determine the position and height of the sliding or rolling surface of the translational building and the flexible shock-isolation layer; select commercial rubber bearings (16) or sliding surface anti-friction materials (5) as the shock-isolation layer for the translational building. The indoor and outdoor floors (13, 14) of the original site of the translation building are excavated to the top of the original foundation (12) offline. Excavate the connection beam (9) hole of the sliding beam on the body of wall (11) of the translational building, and pour reinforced concrete. The two sides of the original foundation (12) of the translational building are enlarged, and the reinforced concrete sliding girders (2) are poured on the enlarged foundation to the sliding or rolling surface and the ...

Abstract

The invention provides a method for reconstructing present shock insulation system of building and relative device, which can reconstruct present system into the ones that meeting flexible shock insulation theory and technique. When in earthquake, the rubber base or slide surface at the bottom of shock insulation building generates horizontal displacement, to insulate or baffle the transmission of earthquake additive force in building, to significantly reduce the damage on the buildings.

Description

Technical field: [0001] The invention relates to a method and device for seismic isolation of buildings, in particular to a method and device for seismic isolation reconstruction of existing buildings. Background technique: [0002] my country is one of the countries with severe earthquake disasters in the world. Thousands of destructive earthquakes have occurred since this century, especially the Tangshan earthquake in 1976, which caused hundreds of thousands of casualties. The lesson is extremely painful. In the new century, major earthquakes occur frequently in the world. For example, there are hundreds of earthquakes above magnitude 5 in the Bachu region of Xinjiang in my country every year. The latest major earthquake has caused thousands of casualties and destroyed hundreds of thousands of houses. [0003] In order to mitigate earthquake disasters, a set of traditional theories and norms of seismic design have been formed in academic circles and engineering circles at ...
