Summary of the invention:
It is single that goal of the invention of the present utility model is to overcome existing base isolation device effect, the deficiency of level of isolation and perpendicular several geological processes and provide a kind of and can effectively alleviate the series connection composite foundation earthquake isolating equipment of vertical earthquake response simultaneously with advancing the level of isolation earthquake.
The utility model adopts following technical scheme:
A kind of series connection composite foundation earthquake isolating equipment, comprise the bottom steel plate, the middle part steel plate, the top steel plate, between described bottom steel plate and the middle part steel plate steel plate group and drag-line are housed, this steel plate group places the symmetrical centre position of bottom steel plate and middle part steel plate, between every adjacent two of this steel plate group beam is housed, described drag-line places around this steel plate group, main steel core post and auxiliary steel core post are housed between described middle part steel plate and the top steel plate, the upper end of this main steel core post and auxiliary steel core post is respectively installed with the top gland that is connected with the top steel plate, the main steel core post of gland lower end, top and auxiliary steel core post are set with the disk spring group outward respectively successively, inner sleeve, shock reducing structure, outer sleeve, the bottom and the middle connecting plate of this outer sleeve are affixed.
The utility model of employing technique scheme compared with prior art, the level and the vertical effect that can effectively weaken seismic forces are also born upper load jointly to the influence of superstructure, has higher vertical bearing capacity, under the normal mode of occupation of building structure, conventional load that can the safety supports superstructure guarantees the normal instructions for use of building structure.And because main steel core post centre, around auxiliary steel core post is distributed on, can effectively hang down the height of isolator, for device provides stability preferably, this device has suitable vertical rigidity, horizontal rigidity and damping capacity, and rigidity and damping are easy to adjust, restore easily the shake back, stable performance.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
A kind of series connection composite foundation earthquake isolating equipment, referring to accompanying drawing 1, form by bottom steel plate 1, rubber pad 2, drag-line 3, middle part steel plate 4, first outer sleeve 5, first shock reducing structure 6, first inner sleeve 7, auxiliary steel core post 8, the first disk spring group 9, the first top gland 10, top steel plate 11, the second top gland 12, main steel core post 13, the second disk spring group 14, second inner sleeve 15, second shock reducing structure 16, second outer sleeve 17, steel plate 18.
Bottom steel plate 1 and middle part steel plate 4 are rectangular respectively, between bottom steel plate 1 and the middle part steel plate 4 steel plate group and the drag-line 3 that is made of steel plate 18 is housed, drag-line 3 is made by SMA (marmem), between every adjacent two steel plates 18 rubber pad 2 is housed, the steel plate group that is made of steel plate 18 places the symmetrical centre position of bottom steel plate 1 and middle part steel plate 4.
Drag-line 3 connects middle part steel plate 4 and bottom steel plate 1 around placing the steel plate group, totally eight of drag-lines 3, and each end face of middle part steel plate 4 is provided with two drag-lines 3, is the right-angled intersection shape and connects bottom steel plate 1.
Between middle part steel plate 4 and the top steel plate 11 main steel core post 13 and auxiliary steel core post 8 are housed, the upper end of main steel core post 13 is set with the second top gland 12 that is connected with top steel plate 11, the main steel core post 13 outer second disk spring group 14, second inner sleeve 15, second shock reducing structure 16, second outer sleeves 17 of being set with successively of 12 lower ends of the second top gland, the bottom of second inner sleeve 15 and second outer sleeve 17 is connected with middle part steel plate 04 respectively, and wherein second shock reducing structure 16 adopts VE viscoelasticity damping material to make.
Auxiliary steel core post 8 is that the centre of gyration is distributed on the steel plate 4 of middle part radially with main steel core post 13, its quantity is four, the upper end of auxiliary steel core post 8 is set with the second top gland 10 that is connected with top steel plate 11, the auxiliary steel core post 8 outer first disk spring group 9, first inner sleeve 7, first shock reducing structure 6, first outer sleeves 5 of being set with successively in the lower end of the first top gland 10, the bottom of first inner sleeve 7 and first outer sleeve 5 is connected with middle part steel plate 4 respectively, and wherein first shock reducing structure 6 adopts VE viscoelasticity damping material to make.
The level and the vertical effect that can effectively weaken seismic forces are also born upper load jointly to the influence of superstructure, has higher vertical bearing capacity, under the normal mode of occupation of building structure, conventional load that can the safety supports superstructure guarantees the normal instructions for use of building structure.And because the master collet centre around auxiliary socket is distributed on, can effectively hang down the height of isolator, for device provides stability preferably, this device has suitable vertical rigidity, horizontal rigidity and damping capacity, rigidity and damping are easy to adjust, and restore easily the shake back, stable performance.
Present embodiment can effectively weaken the level and the vertical effect of seismic forces upper load is also born in the influence of superstructure jointly, has higher vertical bearing capacity, under the normal mode of occupation of building structure, conventional load that can the safety supports superstructure guarantees the normal instructions for use of building structure.And because main steel core post 13 centres, around auxiliary steel core 8 posts are distributed on, can effectively hang down the height of isolator, for device provides stability preferably, this device has suitable vertical rigidity, horizontal rigidity and damping capacity, and rigidity and damping are easy to adjust, restore easily the shake back, stable performance.
