Problems solved by technology

[0004] One of the purposes of the present invention is to provide a tension-resistant device for earthquake-isolated buildings. This tension-resistant device effectively solves the overturning problem of high-rise and super-high-rise earthquake-isolated buildings with large aspect ratios, and makes up for the shortcomings of existing tension-resistant devices.

Embodiment 1

[0027] Embodiment 1: as Figure 1~4 As shown, the tensile device of the earthquake-isolated building includes the upper pre-embedded fixed tensile member, the lower embedded fixed tensile member and the follower limiter;

[0028] The structure of the upper embedded fixed tensile member is the same as that of the lower embedded fixed tensile member, both including 4 anchor rods 1, 4 nuts 2, tensile anchor pads 3, supporting positioning columns 7, and anchor rod positioning plates 8. The tensile anchor plate 3 is provided with a central hole 14 and 4 anchor bolt connection holes 15, and the anchor rod positioning plate 8 is provided with 4 anchor bolt positioning holes 16, and the support positioning column 7 One end is supported on the anchor rod positioning plate 8, and the other end supports the tensile anchor pad 3. The pre-embedded sections of the four anchor rods 1 are treated as right-angled hooks in an "L" shape. The four anchor rods 1 The exposed sections of the anchor...

Embodiment 2

[0036] Embodiment 2: The structure of this embodiment is the same as that of Embodiment 1. The difference is that the number of the upper pre-embedded fixed tensile parts, the lower pre-embedded fixed tensile parts and the follow-up limit parts are 2, and 2 The upper pre-buried fixed tensile parts are symmetrically distributed on both sides of the seismic isolation pier 12 above the seismic isolation support 9, and the two lower pre-embedded fixed tensile parts are symmetrically distributed on the lower seismic isolation pier below the seismic isolation support 9. On both sides of the pier 10, two follow-up limiters are respectively connected with the upper pre-embedded fixed tensile member and the lower pre-embedded fixed tensile member on both sides of the seismic isolation support 9.

[0037] When the assembled tensile device is under the action of an earthquake, when the horizontal shear deformation of the seismic isolation support 9 is less than the design displacement lim...

Abstract

The invention discloses a tensile device and method of anti-seismic buildings, and belongs to the engineering anti-seismic technical field. The tensile device comprises pre-buried fixed tensile piecesand a follow-up limiting piece. According to the different burying positions of the pre-buried fixed tensile pieces in an anti-seismic layer, the pre-buried fixed tensile pieces include the upper pre-buried fixed tensile pieces and the lower pre-buried fixed tensile pieces; when the horizontal shearing deformation of an anti-seismic support reaches a design displacement threshold, the tensile device exerts reverse tensile force on the upper structures of the anti-seismic buildings, the anti-seismic support is prevented from continuing to deform, the horizontal displacement of the anti-seismicbuildings is prevented from exceeding the limit, and the collapsing problem of the high-rise and ultrahigh-rise anti-seismic buildings with large heights is effectively solved; most parts of the device are selected from standard parts, cost is low, construction is simple, the requirement for installation precision is not high, main parts are convenient to replace, performance is stable and controllable, the collapsing problem of anti-seismic buildings can be effectively solved, and the tensile device and method have great significance in increasing the height-width ratio limit value of the anti-seismic buildings and applying the anti-seismic technology to the ultrahigh-rise buildings.

Description

technical field [0001] The invention relates to a tensile device and method for an earthquake-isolated building, belonging to the technical field of engineering anti-seismic technology. Background technique [0002] Earthquake is one of the natural disasters that poses a huge threat to human beings in the world. In order to prevent the great loss of human life and property caused by earthquakes, people are actively engaged in the research of earthquake prediction and structural engineering for earthquake prevention and disaster reduction. Because the causes of earthquakes are very complicated, people's understanding of the earth itself is not enough, so it is still impossible to accurately predict earthquakes. Therefore, building earthquake disaster mitigation has become a research hotspot in this field. Base isolation is one of the better anti-seismic measures. It is different from the so-called rigid anti-seismic vibration through the seismic strength or energy absorption...
