Description

Anti-uplift isolation

The invention relates to an anti-upper isolation isolator; in particular to a device for supporting or preventing vibration or vibration of a general building structure, and a support or shock absorber for mechanical engineering components, having the functions of bearing and horizontal sliding, and bearing vertical tension .

As shown in Fig. 1, the ball is isolated and supported, and the ball device is placed on the base provided with the spherical groove, and the rolling behavior of the ball in the spherical groove achieves the function of isolation and automatic reset.

As shown in Fig. 2, the friction single pendulum isolation support has a spherical sliding sub-assembly on the base provided with the spherical groove, and the sliding action in the spherical groove is used to achieve the isolation and automatic reset. The effect, and the use of sliding friction behavior to achieve energy dissipation.

The above-mentioned vibration-isolating support is not provided with a tensile device, and when subjected to a vertical tensile force, the component of the vibration-isolating support is liable to be detached, so that the vibration-isolating support completely loses its function, and the structure may be dumped and destroyed due to the disassembly of the component.

In order to make the vibration isolation device and the isolated structure have better stability and safety during the earthquake, the anti-uplift isolator is considered to be sandwiched by the movable sub-group on the upper and lower sets of the pedestal with the concave spherical surface. The movable element can be slid or rolled on the concave spherical surface to isolate the horizontal vibration and the vertical load, and the tension connector and the articulated jointer are connected to the upper and lower groups of the bases to be horizontally and vertically intersecting the circular line track. There is no vertical separation between the isolators.

As shown in Figures 3 and 4, the base (20) is provided with four sets of concave spherical surfaces (21), and the concave spherical surface (21) is provided with a circular arc line between the back surfaces. The track (22), the moving element (30) is a rolling actuating ball, and the tensile connector (40) is connected to the latch (41) on the circular arc track of the upper and lower sets of bases by the articulated joint (42). The cassette (41) is rotatable relative to the tension connector (40) so that vertical separation does not occur when the upper and lower groups of bases (20) are horizontally moved relative to each other.

Figure 5 shows the action of the anti-upper isolation (10). When the horizontal relative movement between the upper and lower bases (20) occurs, the tensile connector (40) moves simultaneously with the articulated joint (42). And the angle is converted so that the cassette (41) and the circular line track (22) remain attached.

Figure 6 shows a preferred version of the slider (30) for the slider, and Figure 7 shows a preferred version of the cartridge (30) for the roller.

In the anti-uplash isolator (10) shown in Fig. 8, the movable element (30) is a convex spherical slider that is slidably operated.

As shown in Fig. 9, in the anti-uplash isolators (10), the movable member (30) of the slider is another preferred version of the convex spherical slider that is slidably actuated.

As shown in Fig. 10, in the anti-uplash isolators (10), the movable member (30) of the slider is another preferred version of the convex spherical slider that is slidably actuated.

As shown in Fig. 11, in the anti-uplash isolators (10), the movable member (30) of the slider is another preferred type of the convex spherical slider that is slidably actuated.

Figure 12 is a better application of the anti-uplift isolator (10) placed on the structure (60) A schematic diagram of an embodiment.

Figure 13 is a schematic diagram of a preferred application embodiment of the anti-uplift isolator (10) disposed on the equipment machine or display cabinet.

In Fig. 14, a mass (61) is mounted on the anti-uplash isolator (10) to form a mass damper. The mass damper is placed on the top of the structure (60) or in the floor by the mass. (61) The returning force during the swing counteracts the effect of the earthquake caused by the earthquake or the wind, and has the effect of buffering the horizontal vibration and reducing the amplitude.
