Description
Technical field
The utility model relates to bearing, and particularly a kind of lamination steel-plumbous bearing, belongs to technical field of isolation.
Background technology
Seismic isolation technology increases suitable cushion bottom building and between ground or between supporting construction and superstructure, the acceleration response of building after being subject to ground seismic wave function is weakened greatly, allow the displacement of building bear primarily of shock isolation system simultaneously, thus the distortion making building produce in earthquake is very little, to reach protection object.Isolated component has laminated rubber bases, lead core rubber support, sand cushion, graphite bed course, friction slipper and neoprene bearing and friction slipper compound in parallel etc.Laminated rubber bases and lead core rubber support are the two kinds of forms comparatively commonly used.Laminated rubber damping bearing belongs to steel plate, rubber combined thick product, and general requirements is comparatively large, and the number of plies is many, needs long-time sulfuration.The requirement of sulfuration is also very high, processes improper meeting and causes state of cure (vulcanization) inequality, rubber layer thickness unequal, can cause the unstability of bearing like this.And the damping of normal stack neoprene bearing is unsatisfactory, how to use together with damper, or add lead for retractable pencil formation lead core rubber support to improve the energy dissipation capacity of bearing.But because the distortion of isolation structure Seismic Isolation of Isolation Layer under rarely occurred earthquake effect can up to 350mm, general displacement type damper distortion amplitude far can not meet this technical indicator; And lead block is arranged in lead core rubber support middle hole of drawing on the basis of laminated rubber bases, processing technology is more more complex again than laminated rubber bases.
Utility model content
Based on above-mentioned defect, the utility model proposes a kind of lamination steel-plumbous bearing, the problem of large deformation and highly energy-consuming can not be met in order to solve existing normal stack neoprene bearing.
The technical solution of the utility model is as follows:
A kind of lamination steel-plumbous bearing, described bearing comprises upper and lower cover plate and steel sheet, also comprises stereotype, and described stereotype and steel sheet spacer stack are arranged between upper and lower cover plate, and what be close to inside upper and lower cover plate is stereotype; Described stereotype planar dimension is less than described upper and lower cover plate and steel-sheet planar dimension, and the upper and lower cover plate contacted with described stereotype and steel sheet part are provided with the first groove and the second groove by stereotype planar dimension respectively, described stereotype all or major part be embedded in upper and lower cover plate and steel sheet.
Further, the bight of described upper and lower cover plate is provided with 4 bolts hole, to adopt connecting bolt to be connected with upper and lower part connector.
Further, described upper and lower cover plate is steel plate; Described stereotype is prefabricated cutting stereotype or in-site pouring cooling forming stereotype.
Further, described upper and lower cover plate and steel sheet all adopt Q235 steel plate; Described in-site pouring cooling forming stereotype employing purity is the lead perfusion of 99.99%.
Further, the described upper and lower cover plate (1) contacted with described stereotype (2) and the position of steel sheet (3) are sandblasting or plucking surface.
Further, the shape of described steel sheet and stereotype is square or circular.
Further, described stereotype shape is square or circular, and its length of side or diameter dimension are 500-700mm; Described steel sheet is of a size of square or circle, and its length of side or diameter dimension are 550-750mm, and described upper and lower cover plate shape is square, and its size dimension is 800-1000mm.
Preferably, described stereotype shape is square or circular, and its length of side or diameter dimension are 600mm; Described steel sheet is of a size of square or circle, and its length of side or diameter dimension are 650mm, and described upper and lower cover plate shape is square, and its size dimension is 900mm.
Further, total number of plies that described stereotype and steel sheet are superimposed together is 30-60 layer, and its overall height is 300-700mm.
Preferably, total number of plies that described stereotype and steel sheet are superimposed together is 50 layers, and its overall height is 500mm.
Compared with prior art, the utility model has following beneficial effect:
1. the stereotype that stacks primarily of upper and lower cover plate and upper and lower covers sheet separation of this bearing and steel sheet are formed; Steel-sheet exists makes stereotype suffer restraints in the distortion of shear direction, makes bearing have larger vertical bearing capacity and vertical rigidity.
2. support style simple structure, attractive in appearance, part is less and can prefabrication, precision is guaranteed, can reduce construction error.
3., after structural constraint using function, this bearing convenient disassembly, can reuse after dismounting, economical rationality.
4. the shear strain by lead flake provides plasticity to consume energy, and avoids and installs extra damper or borehole filling lead in laminated rubber bearing.
5. this bearing can provide large deformation energy dissipation capacity by very simple mode, such as displacement amplitude reaches 350mm, this is most of damper or the indeterminable technical indicator of shock isolating pedestal, damped part now in isolation structure generally adopts viscous damper, and its reason is that displacement type damper is difficult to provide the distortion of Seismic Isolation of Isolation Layer under extreme displacement to a great extent.Simultaneously, stromatolithic structure of the present utility model is consistent with the structure of rubber pad in the market, shape also can be consistent with it, need not design in engineering like this damper mount scheme what, need to increase damping, directly some rubber pad is replaced by lead pad just passable, design and construction all convenient.
6. arrange in pairs or groups to use with laminated rubber bases and can make up mutual defect.
