Embodiment 1

[0052] like Figure 1 to Figure 4 and Figure 21As shown, a self-resetting combined swing impact energy-dissipating shock-isolating device of the present invention includes a grooved upper support 1, a corresponding grooved lower support 2, and a middle of the two supports A freely placed columnar rocking impact energy dissipation block 3 and a group of two-stage tension limiting auxiliary devices 4. The upper support 1 and the lower support 2 are respectively connected with the upper structure and the foundation through embedded parts. The swing impact energy consumption block 3 can swing freely, and the depth of the swing impact energy consumption block 3 embedded in the grooves 13 and 23 of the upper support 1 and the lower support 2 is greater than that of the swing impact energy consumption block 3 on the contact surface 10, One side of 20 is the design value of the lifting height of the other side when the fulcrum is swinging. The second-stage tension limiting auxilia...

Embodiment 2

[0054] like Figure 5-8 and Figure 21 As shown, in the second preferred solution of the present invention, it includes a grooved upper support 1, a corresponding grooved lower support 2, and a freely placed columnar swing impact energy dissipation in the middle of the two supports. Block 3 and a group of two-stage tension limiting auxiliary devices 4. The upper support 1 and the lower support 2 are respectively connected with the upper structure and the foundation through embedded parts. The columnar rocking impact energy dissipation block 3 can swing freely, and the depth of the grooves 13 and 23 embedded in the upper support 1 and the lower support 2 is greater than that of the swinging impact energy dissipation block 3 on the contact surface 10 , One side of 20 is the design value of the lifting height of the other side when the fulcrum is swinging. The second-stage tension limiting auxiliary device 4 is fixed on the periphery of the upper support 1 and the lower suppor...

Embodiment 3

[0056] like Figure 9-12 and Figure 22 As shown, in the third preferred solution of the present invention, it includes a grooved upper support 1, a corresponding grooved lower support 2, and a freely placed columnar swing impact loss in the middle of the two supports. Energy block 3 and a group of two-stage tension limiting auxiliary devices 4. The upper support 1 and the lower support 2 are respectively connected with the upper structure and the foundation through embedded parts. The columnar rocking impact energy consumption block 3 can swing freely, and the depth of the grooves 13, 23 embedded in the upper support 1 and the lower support 2 is greater than that of the rocking impact energy consumption block 3 on the contact surface 10, One side of 20 is the design value of the lifting height of the other side when the fulcrum is swinging. The second-stage tension limiting auxiliary device 4 is fixed on the periphery of the upper support 1 and the lower support 2 through ...

Abstract

The invention discloses a self-centering combined swinging and impacting energy consumption seismic isolation device. The device comprises an upper support and a lower support, which are opposite to each other, wherein grooves are formed in the opposite surfaces of the upper and lower supports; a swinging and impacting energy consumption block is arranged between the upper and lower supports, and the two ends of the swinging and impacting energy consumption block are arranged in the grooves of the upper and lower supports respectively; an auxiliary pulled limiting device is further arranged between the upper and lower supports to limit the relative movement distance of the upper and lower supports in stages; a soft material is arranged between the end part of the hard swinging and impacting energy consumption block and the upper and lower supports; the swinging and impacting energy consumption block is not adhered to the upper and lower supports. According to the device, the lifting and falling impacting action of the swinging and impacting energy consumption block is utilized for seismic isolation, and structural deformation is concentrated into a seismic isolation system, so that damage to a main body structure is reduced and even avoided; different materials are combined for use in the seismic isolation device, so that the damage of swinging actions to the seismic isolation device is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a self-resetting combined swing impact energy-consuming shock-isolation device. Background technique [0002] my country is a country severely affected by earthquakes, with high frequency of earthquakes, strong earthquakes with shallow focus and wide distribution. The casualties and direct economic losses caused by earthquakes in our country are huge every year. [0003] Ordinary concrete buildings designed according to codes can no longer fully meet the growing seismic demand of buildings. The structure needs to be under the action of earthquakes and other disasters without excessive damage to the structure, and after the disaster can be repaired under reasonable technical and economic conditions to restore its expected function, that is, the damage controllable structure. [0004] Structural damage is reflected in the overall effect of component damage, including th...
