Traditional ball shaped steel bearing only has pressure-bearing, displacement and rotating function, but without energy consumption effect, when earthquake produces larger horizontal force, support body can occur to destroy and cause its disabler, cause bridge structure to suffer damage, jeopardize people's life and property safety.On the other hand, in recent years, the increasing with country to infrastructure construction dynamics, bridge has obtained the development of high speed, the especially construction of high-speed railway bridge and city rail bridge with architectural engineering, and technical performance and function to spherical bearing propose requirement higher.In order to develop the ball shaped steel bearing with dissipation seismic energy, the present invention explores a kind of energy-dissipating type ball shaped steel bearing.Prior art, is mainly buffered and is consumed energy by rubber or friction pair, such as patent has the spherical bearing of power consumption friction pair(CN201581517U), shock-proof damper ball type support base(CN2705494Y), the entitled spherical bearing with power consumption friction pair(Publication No.:CN201581517U), bearing has multiple friction pairs, and the coefficient of friction difference very little of each friction pair is difficult to ensure that power consumption friction pair can play one's part to the full;High-damping rubber is easily affected by environment, causes its hydraulic performance decline.Entitled shock-proof damper ball type support base(Publication No. CN2705494Y)It is squeezed power consumption only with high-damping rubber, energy consumption effect is still to be tested.
The content of the invention
The present invention is on the basis of existing ball shaped steel bearing, there is provided a kind of steel damping energy dissipation type ball shaped steel bearing, it is therefore intended that consumed energy using steel damping element, Energy Dissipation Mechanism is clear and definite, it is not easy to affected by environment, energy consumption effect is good.In addition to it can meet the normal service condition of bridge or building, bridle iron of the present invention can make steel damping element dissipation seismic energy when bearing earthquake displacement is larger, can effectively protect bearing not to be damaged and come off, and protect bridge or structural safety.
To reach above-mentioned purpose, the technical solution adopted by the present invention is as follows:A kind of steel damping energy dissipation type ball shaped steel bearing, including anchor rod, upper base plate, stainless steel plate, planar lasting board, spherical crown liner plate, spherical wearing plate, lower seat board, the lower seat board edge of a wing, the upper base plate edge of a wing and steel damping element, the upper base plate edge of a wing is fixedly connected and downwardly projecting with upper base plate, the lower seat board edge of a wing is fixedly connected and protruding upward with lower seat board, and steel damping element is connected between the lower seat board edge of a wing and the upper base plate edge of a wing.
Further, steel damping element is connected between lower seat board edge of a wing inner side and upper base plate edge of a wing outside by otic placode.
Further, steel damping element shape is c-type, semicircle type, circle, and steel damping element is elastoplasticity dissipative cell.
Further, with certain gap when steel damping element is connected with otic placode, to facilitate steel damping element to adapt to the normal displacement of bearing.
Further, steel damping element arrangement is single or multiple, is arranged to together with direction across bridge in bridge direction across bridge arrangement, or the vertical bridge of bridge.
Further, upper base plate edge of a wing upper end is wide, and lower end is narrow, is inverted trapezoidal section, and the inner edge in inverted trapezoidal section can be straight line or camber line.
Further, the upper base plate edge of a wing and seat of honour plate weld or global formation.
Further, the lower seat board edge of a wing is welded or global formation with lower seat board.
Further, anchor rod Surface Machining has the diagonal rib of projection, increases the cementation of anchor rod and concrete.
The present invention makes it have following advantage and beneficial effect due to using above structure:
1.)The effect of bearing bearing capacity over one's competence is reached by setting the inverted trapezoidal upper base plate edge of a wing and the lower seat board edge of a wing;
2.)The energy dissipation capacity of bearing is realized by being connected with steel damping element between the lower seat board edge of a wing and the upper base plate edge of a wing.During so as to protecting bridge to bear greater level power, support body will not be destroyed, and protection bridge structure exempts from damage and destroys.
