Track type tensile support

Abstract

The invention relates to a track type tensile support which comprises an upper track connected with an upper building, a lower track connected with a lower building and a sliding track steering block used for connecting the upper track with the lower track, wherein the upper track and the lower track are connected with the sliding track steering block in a sliding manner, and the sliding direction of the lower track relative to the sliding track steering block is vertical to the sliding direction of the upper track relative to the sliding track steering block. Compared with the prior art, the track type tensile support has the advantages of strong tensile capacity and capacity of realizing the large displacement motion in the horizontal direction, and can be applied in the fields of buildings and bridges, effectively reduce the impacts caused by earthquake disasters and protect life and property security.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and bridge engineering, in particular to a tensile bearing used for civil engineering structures and bridge structures. Background technique [0002] In the design of building structures, the installation of shock-isolation and shock-absorbing bearings can effectively reduce earthquake disasters. [0003] According to the requirements of the national standard GB50011-2001 "Code for Seismic Design of Buildings", rubber seismic isolation bearings are usually used as seismic isolation devices, but rubber seismic isolation bearings can only withstand the pressure transmitted from above, and the ability to withstand tensile forces is limited. Under the action of an earthquake, the seismic isolation bearings of medium and high-rise buildings usually need to bear a large tensile force, but the tensile capacity of the existing seismic isolation bearings is insufficient; at the same time, the bu...

[0003] According to the requirements of the national standard GB50011-2001 "Code for Seismic Design of Buildings", rubber isolation bearings are usually used as isolation devices, but rubber isolation bearings can only withstand the pressure transmitted from above, and the ability to withstand tension is limited

Under the action of an earthquake, the seismic isolation bearings of medium and high-rise buildings usually need to bear a large tensile force, but the tensile capacity of the existing seismic isolation bearings is insufficient; at the same time, the building may also undergo a large horizontal displacement, and the existing bearings The range of allowable horizontal displacement is relatively small, which cannot meet the requirements of buildings and bridges to resist large-intensity earthquakes in engineering practice
