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 constructure shakeproof apparatus, be specifically related to a kind of overturn-preventing lift-off T-shaped slippage lever of shock isolating pedestal.
Background technology
In order to improve the damping effect of building, be provided with shock isolating pedestal when constructing between building and ground, shock isolating pedestal possesses four kinds of characteristics: bearer properties, shock insulation characteristic, reset feature and energy dissipation behavior.Due to following problem: 1, highrise building depth-width ratio is relatively large, effect of toppling is obvious; 2, in macroseism, Vertical Seismic Load is often very large, and this makes Seismic Isolation of Isolation Layer often have lift-off phenomenon; Current shock isolating pedestal does not possess overturn-preventing lift-off characteristic, so shock isolating pedestal tension problem becomes one of major obstacle that seismic isolation technology applies in highrise building, and the destruction of macroseism to shock isolating pedestal is difficult to avoid.
Summary of the invention
The object of the invention is to: the overturn-preventing lift-off T-shaped slippage lever providing a kind of shock isolating pedestal, shock isolating pedestal assisted by this T-shaped slippage lever, solves shock isolating pedestal tension problem.
Technical solution of the present invention is: this T-shaped slippage lever comprises horizontal lever, longitudinal lever, a fixed block, No. two fixed blocks, No. three fixed blocks and tension bolts, chute opened by horizontal lever, one end of horizontal lever is through pinned connection fixed block, longitudinal lever is placed above the other end of horizontal lever, the two ends of longitudinal lever connect No. two fixed blocks and No. three fixed blocks respectively, tension bolt plug-in type is arranged in the chute of horizontal lever, overall formation T-shaped slippage lever.
During construction, T-shaped slippage lever in parallel between building with ground, by shock isolating pedestal, a fixed block, No. two fixed blocks, No. three fixed blocks of T-shaped slippage lever fix on the ground, connect earth anchor under it, have very strong resistance to tension, the top of tension bolt is connected to building; When building produces uplift force, T-shaped slippage lever is directly delivered to ground and earth anchor below thereof vertically downward power, and power is dissipated, and shock isolating pedestal in parallel with it can not the effect of tension power, also would not produce lift-off phenomenon of toppling.
The present invention has the following advantages: 1, vertical direction: T-shaped slippage lever makes the distance on building and ground remain unchanged, and shock isolating pedestal is the effect of tension power not, avoids generation to topple lift-off phenomenon; 2, horizontal direction: horizontal lever and tension bolt all can horizontal slidings, their synergies do not have an impact to the horizontal movement in any direction of shock isolating pedestal; 3, on the bearer properties of shock isolating pedestal, reset feature and energy dissipation behavior without any impact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 horizontal lever, 2 longitudinal levers, No. 3 fixed blocks, 4 No. two fixed blocks, 5 No. three fixed blocks, 6 tension bolts, 7 chutes, 8 bearing pins.
Detailed description of the invention
As shown in Figure 1, this T-shaped slippage lever comprises horizontal lever 1, longitudinal lever 2, fixed block 3, No. two fixed blocks 4, No. three fixed blocks 5 and tension bolt 6, chute 7 opened by horizontal lever 1, one end of horizontal lever 1 connects a fixed block 3 through bearing pin 8, longitudinal lever 2 is placed above the other end of horizontal lever 1, the two ends of longitudinal lever 2 connect No. two fixed blocks 4 and No. three fixed blocks 5 respectively, and tension bolt 6 plug-in type is arranged in the chute 7 of horizontal lever 1, overall formation T-shaped slippage lever.
During construction, at the other T-shaped slippage lever in parallel of shock isolating pedestal, a fixed block 3, No. two fixed blocks 4, No. three fixed blocks 5 of T-shaped slippage lever fix on the ground, the top of tension bolt 6 is connected to building, the bearing pin end of horizontal lever 1 is rotatable, the other end end of horizontal lever 1 can slippage under longitudinal lever, and tension bolt 6 can slippage in the chute 7 of horizontal lever 1; When building produces uplift force, the transmission dissipation approach of power is: the bearing pin end of building → tension bolt 6 → horizontal lever 1 → horizontal lever 1 and the other end; Again by the bearing pin end → No. mono-fixed block 3 → ground of horizontal lever 1, and the other end of horizontal lever 1 → longitudinal lever 2 → No. bis-fixed blocks 4 and No. three fixed block 5 → ground; When secondary wave makes shock isolating pedestal (building) produce horizontal movement, horizontal lever 1 bearing pin end rotates, the other end of horizontal lever 1 is in the 2 times slippages of longitudinal lever, collaborative tension bolt 6 slippage in the chute 7 of horizontal lever 1, at which direction T-shaped slip lever all can not have an impact to the horizontal movement of shock isolating pedestal.
Claims (1)
1. the overturn-preventing lift-off T-shaped slippage lever of shock isolating pedestal, it is characterized in that: this T-shaped slippage lever comprises horizontal lever (1), longitudinal lever (2), a fixed block (3), No. two fixed blocks (4), No. three fixed blocks (5) and tension bolt (6), horizontal lever (1) opens chute (7), one end of horizontal lever (1) connects a fixed block (3) through bearing pin (8), longitudinal lever (2) is placed above the other end of horizontal lever (1), the two ends of longitudinal lever (2) connect No. two fixed blocks (4) and No. three fixed blocks (5) respectively, tension bolt (6) plug-in type is arranged in the chute (7) of horizontal lever (1), overall formation T-shaped slippage lever.
