Description

Technical Field

[0001] The invention belongs to the field of earthquake-resistant reconstruction of buildings, and in particular relates to a stepped tension-compression-shearing type building shock-absorbing structure. Background Art

[0002] Adding floors and remodeling projects have a significant effect on saving land, reducing project costs and many other aspects. In general, the addition and renovation of houses can be divided into the addition and renovation of civil and industrial houses. Among them, civil buildings such as residential buildings, office buildings, hospitals, hotels, shops, etc. are relatively large and wide-ranging buildings, and the policy of demolishing and rebuilding them all cannot be adopted. According to the survey, there are a large number of low-rise or multi-story civil buildings in towns and cities, which cannot be stopped from use and urgently need to expand the use area. Adding floors in combination with improving the use function of houses or overhauling them is an important way to transform and utilize low-rise or multi-story houses into multi-story, medium and high-rise houses. Some of these buildings were not seismically fortified in the past construction or the fortification standards were low. Such buildings can be reinforced and remodeled to achieve the purpose of improving the use function of houses, seismic reinforcement and structural energy dissipation and shock absorption, ensuring that the connection is sufficiently stable while improving the seismic performance. Earthquake disasters are sudden and destructive, and seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur in the world every year. A major earthquake can cause economic losses of hundreds of billions of dollars and lead to the death or serious disability of hundreds of thousands of people. During an earthquake, the poor seismic resistance of the structural connections of the multi-storey buildings can easily lead to a large amount of damage and collapse, causing serious damage to the main load-bearing structure or even collapse, which is the direct cause of earthquake disasters. In order to avoid the occurrence of the above-mentioned disasters, people must control the seismic response of the multi-storey building structure and eliminate the poor seismic resistance, so that it has sufficient rigidity to meet the use requirements during small winds or small earthquakes. When a large earthquake or strong wind occurs, the structure has a certain elastic effect and produces a large damping, which can consume a large amount of earthquake or wind vibration energy input into the structure, so that the structural kinetic energy or elastic potential energy and other energies are converted into heat energy and dissipated, protecting the structure from damage in strong earthquakes or strong winds. The multi-storey building structure currently developed has poor seismic resistance, so the manufacturing process and energy consumption capacity still need to be further improved. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides a stepped tension-compression-shear type shock-absorbing structure. The present invention can well protect the collision, pulling or shearing process between the two, and can allow the original and the added-story buildings to move slightly with the earthquake shear and collision pulling process without causing rigid damage. When shear movement occurs, the kinetic energy of the shear seismic sliding energy-absorbing plate and the shear compression shock-absorbing spring and the shear displacement damping layer squeeze each other. When the shear reaches the limit, the shear energy-absorbing shock-absorbing ribs on the shear seismic sliding energy-absorbing plate can dissipate energy to resist earthquakes, and play a stepped seismic and shock-absorbing effect. The present invention is suitable for structures under construction that have not been seismically fortified or have low fortification standards, especially for reinforcing and adding stories to such buildings to achieve seismic reinforcement and structural energy dissipation and shock-absorbing functions.

The low construction cost is a significant advantage of the present invention. The present invention is suitable for structures under construction that have not been seismically fortified or have low fortification standards, especially for reinforcing and adding floors to such buildings to achieve seismic reinforcement and structural energy dissipation and shock absorption functions.
