Abstract
The invention discloses an overturn and lift-off prevention T-shaped sliding lever of a shock-insulative base. The T-shaped sliding lever comprises a transverse lever (1), a longitudinal lever (2), a first fixing block (3), a second fixing block (4), a third fixing block (5) and a tensile plug (6), wherein a sliding groove (7) is formed on the transverse lever (1); one end of the transverse lever (1) is connected with the first fixing block (3) through a pin shaft (8), and the longitudinal lever (2) is arranged at the other end of the transverse lever (1); two ends of the longitudinal lever (2) are respectively connected with the second fixing block (4) and the third fixing block (5); and the tensile plug (6) is arranged in the sliding groove (7) of the transverse lever (1) in an inserted mode. Through force transmission in the vertical direction, upward pulling force is dissipated to ensure that the distance between a building and the ground remains unchanged; the shock-insulative base is not affected by drawing force to avoid generation of the overturn and lift-off phenomenon; and both the transverse lever and the tensile plug can horizontally slide, and horizontal displacement of the shock-insulative base in different directions is not affected by combined effect of the transverse lever and the tensile plug.
Description
Technical field
The present invention relates to the constructure shakeproof apparatus, the overturn-preventing that is specifically related to a kind of shock isolating pedestal is lifted from "T"-shaped slippage lever.
Background technology
In order to improve the damping effect of building, be provided with shock isolating pedestal between building and ground when construction, shock isolating pedestal possesses four specific characters: bearer properties, shock insulation characteristic, reset feature and energy dissipation behavior.Due to following problem: 1, the highrise building depth-width ratio is relatively large, and the effect of toppling is obvious; 2, in macroseism, Vertical Seismic Load is often very large, and this makes Seismic Isolation of Isolation Layer often lift from phenomenon; Present shock isolating pedestal does not possess overturn-preventing and lifts from characteristic, so shock isolating pedestal tension problem becomes one of major obstacle that seismic isolation technology applies in highrise building, macroseism is difficult to avoid to the destruction of shock isolating pedestal.
Summary of the invention
The object of the invention is to: provide a kind of overturn-preventing of shock isolating pedestal to lift from "T"-shaped slippage lever, this "T"-shaped slippage lever is assisted shock isolating pedestal, solves shock isolating pedestal tension problem.
Technical solution of the present invention is: this "T"-shaped slippage lever comprises horizontal lever, vertically lever, fixed block, No. two fixed blocks, No. three fixed blocks and tension bolt, laterally open chute on lever, laterally an end of lever connects a fixed block through bearing pin, laterally vertical lever is placed in the other end of lever top, vertically the two ends of lever connect respectively No. two fixed blocks and No. three fixed blocks, tension bolt plug-in type is arranged in the chute of horizontal lever, the "T"-shaped slippage lever of whole formation.
During construction, between building and ground, the other "T"-shaped slippage lever in parallel of shock isolating pedestal, a fixed block of "T"-shaped slippage lever, No. two fixed blocks, No. three fixed blocks fix on the ground, its lower connection earth anchor, very strong resistance to tension is arranged, and the top of tension bolt is connecting building; When building produced uplift force, "T"-shaped slippage lever directly was delivered to ground and following earth anchor thereof to power vertically downward, and power is dissipated, and shock isolating pedestal in parallel can the effect of tension power with it, just can not produce to topple yet and not lift from phenomenon.
The present invention has the following advantages: 1, vertical direction: "T"-shaped slippage lever remains unchanged the distance on building and ground, and shock isolating pedestal is the effect of tension power not, avoids generation to topple and lifts from phenomenon; 2, horizontal direction: but horizontal lever and tension bolt horizontal sliding all, and their synergies do not exert an influence to the horizontal movement of any direction of shock isolating pedestal; 3, on bearer properties, reset feature and the energy dissipation behavior of shock isolating pedestal without any impact.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure: 1 horizontal lever, 2 vertical levers, No. 3 fixed blocks, 4 No. two fixed blocks, 5 No. three fixed blocks, 6 tension bolts, 7 chutes, 8 bearing pins.
The specific embodiment
As shown in Figure 1, this "T"-shaped slippage lever comprises horizontal lever 1, vertically lever 2, fixed block 3, No. two fixed blocks 4, No. three fixed blocks 5 and tension bolt 6, laterally open chute 7 on lever 1, laterally an end of lever 1 connects a fixed block 3 through bearing pin 8, laterally vertical lever 2 is placed in the other end of lever 1 top, vertically the two ends of lever 2 connect respectively No. two fixed blocks 4 and No. three fixed blocks 5, tension bolt 6 plug-in types are arranged in the chute 7 of horizontal lever 1, the "T"-shaped slippage lever of whole formation.
During construction, at the other "T"-shaped slippage lever in parallel of shock isolating pedestal, a fixed block 3 of "T"-shaped slippage lever, No. two fixed blocks 4, No. three fixed blocks 5 fix on the ground, the top of tension bolt 6 is connecting building, laterally the bearing pin end of lever 1 is rotatable, laterally the other end end of lever 1 can be in slippage under vertical lever, and tension bolt 6 can slippage in the chute 7 of horizontal lever 1; When building produced uplift force, the transmission dissipation approach of power was: bearing pin end and the other end of building → tension bolt 6 → horizontal lever 1 → horizontal lever 1; Again by the bearing pin end of horizontal lever 1 → No. a fixed block 3 → ground, 2 → No. two fixed blocks 4 of lever of and the other end of horizontal lever 1 → vertically and No. three fixed block 5 → ground; When the earthquake shear wave makes shock isolating pedestal (building) produce horizontal movement, laterally lever 1 bearing pin end rotates, laterally the other end of lever 1 is in vertically 2 times slippages of lever, work in coordination with or tension bolt 6 slippage in the chute 7 of horizontal lever 1, can the horizontal movement of shock isolating pedestal not exerted an influence at the "T"-shaped slip lever of which direction.
Claims (1)
1. the overturn-preventing of shock isolating pedestal is lifted from T shape slippage lever, it is characterized in that: this T shape slippage lever comprises horizontal lever (1), vertical lever (2), a fixed block (3), No. two fixed blocks (4), No. three fixed blocks (5) and tension bolt (6), laterally open chute (7) on lever (1), laterally an end of lever (1) connects a fixed block (3) through bearing pin (8), laterally vertical lever (2) is placed in the other end of lever (1) top, vertically the two ends of lever (2) connect respectively No. two fixed blocks (4) and No. three fixed blocks (5), tension bolt (6) plug-in type is arranged in the chute (7) of horizontal lever (1), whole formation T shape slippage lever.
