Embodiment

[0024] Such as Figure 1-3 The earthquake-resistant height-increasing structure shown is composed of a low building 8 and a height-increasing structure 1. The earthquake-resistant rigid-flexible space building and space real estate height-increasing structure 1 are divided into three rigid sections A, B, and C. In the rigid sections A and B , B and C, and C and the foundation 18 are respectively provided with shock-isolation and shock-absorbing devices 2, and the rigid section C of the height-increasing structure 1 spanning the low and low buildings 8 is composed of a bearing girder 9, a column 10 and a crossbeam 11 between the columns 10 The frame is provided with a shock-absorbing pit 3 on the outside of the column 10 and the foundation 16, and easily compressible building materials or waste materials 4 are filled between the walls of the reinforced concrete pit. The shock-isolation and shock-absorbing device 2 adopts rubber laminated cushion layers placed at intervals, and l...

Abstract

The invention belongs to a building energy saving and emission reduction: the existing building anti-seismic heightening structure, which is mainly composed of the original low building, heightening structure, shock isolation and shock absorbing device and coupling device, between the superstructure of the heightening structure and its foundation or the superstructure A shock-isolation and shock-absorbing device is provided in the horizontal direction or vertical direction between each rigid section of the structure, a coupling device is provided between the height-increasing structure and the original low building, and a load-bearing structure is installed above the height-increasing structure spanning the low building. girder. The main advantage of this earthquake-resistant space building and the height-increasing structure of space real estate is that it not only improves the earthquake resistance of the original low-slung buildings, but also protects the original low-slung buildings from continuing to be used, which can save investment by 30% compared with large-scale demolition and reconstruction. -60%.

Description

Technical field: [0001] The invention belongs to an anti-seismic heightening structure of an existing building, in particular to an anti-seismic characteristic heightening structure above the original low building. Background technique: [0002] The anti-seismic heightening structure of existing buildings is a new topic in urban construction. As far as the specific situation of our country is concerned, urban buildings from the 1950s to the 1960s were basically 3-5 storeys, and some 6-9 storeys began to appear in the 1970s. In the 1980s, with the increase of population and With the development of economic construction, the planning requirements of new urban buildings are basically more than 6 floors. According to my country's national conditions, in the use and management of buildings, it is not possible to generally use elevators, generally 6-9 floors are beneficial. my country has a large population and little arable land, and urban development is restricted. According t...
