Abstract
The utility model discloses a variable stiffness elastic steel support base used for engineering structures, which comprises an upper cover, a middle core, a base and a fixed box body. The side wall of the upper cover is fixed with a variable stiffness elastic damping device through screw bolts, wherein, the variable stiffness elastic damping device is formed by fixing a plurality of bow-shaped spring plates on the side wall of the upper cover through screw bolts. The variable stiffness of the utility model can be realized by a regulating plate which can be regulated by a screw bolt, can be realized by adopting a bow-shaped spring plate with variable cross sections, and can be realized by simultaneously adopting the two modes. The variable stiffness elastic steel support base used for engineering structures has strong damping capability and strong earthquake resistance capability, and can be suitable for the requirements of different stiffness. Therefore, the utility model can be used in various engineering structures, such as building structures, bridge structures, hydraulic engineering structures, etc.
Description
Technical field
The utility model relates to a kind of Engineering Structure Component, particularly a kind of bearing that is used for engineering structures.
Background technology
In the design and construction of bridge, building engineering structure, must consider the influence that earthquake, vibration etc. cause engineering structures.Bearing is a kind of structural vibration reduction element that engineering construction is particularly widely applied in the bridge engineering, not only will give substructures such as bridge pier, column the weight transfer of central structure in bridge and other building structure, but also will have vibration damping and earthquake-resistant effect.Recently the ball crown type bearing occurred, this bearing is made of loam cake, spherical SMIS and the base that has a hemisphere face cavity, and this bearing can adapt to the moment of flexure on all directions, and the resist displacement ability is strong, but its vibration damping and antiseismic ability are relatively poor.
The content of utility model
At the vibration damping of existing ball crown type bearing and the problem of earthquake resisting performance difference, the purpose of this utility model is providing a kind of change rigidity Elastic Steel bearing, the vibration damping and the shock resistance of this steel support are strong, but the not only vibration of the Chinese People's Anti-Japanese Military and Political College and earthquake, and because it is for becoming rigidity, so can adapt to the needs of different-stiffness.
To achieve these goals, the technical solution of the utility model is: become rigidity Elastic Steel bearing, comprise loam cake, SMIS and base, also comprise a static housing, base, SMIS and loam cake are installed in the static housing, become the rigidity elastic vibration clamper and are fixed on and cover having between loam cake sidewall and the wall box.
Above-mentioned change rigidity elastic shock-absorbing device can be semielliptic spring plate group, is fixed on the loam cake sidewall by screw rod, and the two ends of outmost spring plate contact with the sidewall of static housing, and the elastic board chip of latch plate group is the thin variable cross-section shape in thick middle two ends.
Above-mentioned change rigidity elastic shock-absorbing device also can be made up of the semielliptic spring plate group and the rigidity adjustable plate that are fixed on the loam cake sidewall, the rigidity adjustable plate is parallel with the side plate of static housing, a plurality of adjusting bolts are installed in the screwed hole of wall box, and the top is regulated to analyse with rigidity and contacted; The outmost latch plate of semielliptic spring plate group two ends contact with the rigidity adjustable plate.The elastic board chip of its semielliptic spring plate group also can be the thin variable cross-section shape in thick middle two ends.
Change rigidity Elastic Steel bearing of the present utility model is owing to adopted elastic device between loam cake and static housing sidewall, so good absorbing, vibration damping, anti seismic efficiency can be arranged, make the vibration of going up central structure be difficult to pass to substructure, because the vibration of the lower member that earthquake causes also is difficult for passing to upper component.Owing to adopt the spring plate of variable cross-section to become the rigidity elastic device, the needs that not only can adapt to different-stiffness, and make that the distortion of elastic device and suffered pressure are non-linear relation, its adaptive ability is strong, make the scope of application wider, bigger vibration force can be adapted to, less vibration force can be adapted to again.The employing of rigidity adjustable plate effectively in the installation of bearing, can be carried out under stress-free conditions during installation, installs the back and will adjust the rigidity of elastic device by adjusting the adjusting bolt according to shaking, and make bigger vibration of its adaptation and the earthquake requirement to rigidity.
Description of drawings
Fig. 1 is the structure chart of the change rigidity Elastic Steel bearing of embodiment 1 of the present utility model;
Fig. 2 is the vertical view of change rigidity Elastic Steel bearing shown in Figure 1;
Fig. 3 is the structure chart of the change rigidity Elastic Steel bearing of embodiment 2 of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but embodiment only is used for change rigidity Elastic Steel seat structure of the present utility model and principle are described further, and its specific embodiment is not limited in the content among the embodiment.
With reference to Figure 1 and Figure 2, become rigidity Elastic Steel bearing and comprise a loam cake 1, SMIS 2 and base 3, SMIS 2 is between loam cake 1 and base 3, be installed in the static housing 8 by the guide rail (not shown), rigidity adjustable plate 6 is arranged in static housing 8, regulate in the screw of sidewall that bolt 7 is installed in static housing 8, regulate bolt 7 tops and be against on the adjustable plate 6 for two.By bolt 4 the latch plate group of being made up of a plurality of semielliptic spring plates 5 is installed on the sidewall of loam cake 1, the cross sectional shape of spring plate is a variable cross-section, and the thick middle both sides are thin, and outmost spring plate two ends are against on the adjustable plate 6.Construction will become rigidity Elastic Steel bearing installation in position earlier man-hour, adjust adjusting bolt 7 and push adjustable plate, and extruding semielliptic spring plate group is to desired location.
Because the latch plate in the latch plate group 5 is a variable cross-section, so its distortion is very little when being subjected to bigger extruding force, so the scope of application is bigger.And can adjust its rigidity by the position of regulating adjustable plate, to adapt to the needs of engineering structures different-stiffness.
As shown in Figure 3, in the present embodiment, be fixed with semielliptic spring plate group 15 in last 11 lid sides by bolt 14, latch plate wherein is a variable cross-section, and promptly the thick middle two ends are thin.The two ends of outmost latch plate are against on the sidewall of fixed case 18.
