Description
Technical field
The utility model relates to a kind of shock-proof ball shaped steel bearing that subtracts, and relates to a kind of unidirectional activity or rather and subtracts shock-proof ball shaped steel bearing.Belong to the bridge engineering field of components.
Background technology
Along with the development of bridge and space structures engineering, ball shaped steel bearing has been widely used on highway and the engineerings such as railroad bridge and space truss structure.The domestic and international at present ball shaped steel bearing that generally uses, its primary structure is, have seat board and under the bearing that can be fixed on the bridge pedestal and can be fixed on bearing upper bracket plate (top board) on the Bridge Beam base plate, close-fitting is provided with the spherical crown steel liner plate in the bearing lower support plate and between the bearing top board.Spherical crown steel liner plate planar section is embedded with a polytetrafluoroethylene (PTFE) slide plate, and forms the planar friction pair with the corrosion resistant plate that places bearing top board lower plane; Land portions forms the pivoting friction pair with the sphere polytetrafluoroethylene (PTFE) slide plate that is embedded in lower support plate concave surface place.By said prior art as seen, do not have antidetonation and energy-dissipating device in the structure, do not possess antidetonation and shock-absorbing function.Therefore will be restricted in the higher regional use of earthquake intensity.China is the earthquake hotspot, and in order to reduce the destruction that earthquake causes to bridge, have relatively high expectations to the providing fortification against earthquakes bridge pad in area of research has important value.
Summary of the invention
The purpose of this utility model provides a kind of ball shaped steel bearing that has antidetonation and damping effectiveness simultaneously, and existing opposing horizontal force has the energy-dissipating and shock-absorbing effect again, can cut down the earthquake peak value, makes bridge exempt from sudden destruction.According to the requirement of bridge, this shock-proof ball shaped steel bearing that subtracts can be divided into unidirectional activity and fix two types the bearing difference in functionality.
The technical solutions of the utility model that realize above-mentioned purpose are, similar to prior art have basin and at the bottom of the bearing that can be fixed on the bridge pier and can be fixed on bearing top board on the Bridge Beam base plate, and the bearing top board places on the plane polyfluortetraethylene plate of spherical crown steel liner plate.Characteristics of the present utility model are, the one, earthquake resistant structure is set in bearing.Change non-glide direction baffle plate of bearing top board and the incorporate way of top board (upper bracket plate), the baffle plate of non-glide direction is adopted bolt fixed mode with being connected of top board, and set up the shear-pin identical with bolt quantity, make baffle plate change shearing-resistance blocks into, also promptly be provided with the shearing-resistance blocks that is connected with shear-pin with bolt, form earthquake resistant structure in the non-glide direction side of bearing top board.When strong horizontal force produces, bearing concave surface steel liner plate extruding shearing-resistance blocks, when extruding force surpassed the yield strength of shear-pin and bolt, both were cut off, earthquake resistant structure generation effectiveness.The 2nd, seismic isolation and reduction structure is set in bearing, former lower support plate is divided into two, promptly be divided into concave surface steel liner plate and end basin, and the concave surface steel liner plate places in the end basin, and be installed with energy dissipating plate at concave surface steel liner plate soffit; In the pelvic cavity of end basin, be installed with energy dissipating plate; Be installed with a damping shock absorption circle at end basin inner edge mouth again.Thus, the utility model makes between bearing concave surface steel liner plate and the end basin, that is has formed a dry friction slide surface between the upper and lower energy dissipating plate, produces slippage under the earthquake horizontal force action, and it is as the dry-friction damping earthquake energy.Meanwhile, the damping shock absorption circle of basin inner edge mouth can produce crimp at the bottom of the bearing, and seismic energy is released, and has consumed seismic energy once more.And at ordinary times, since bearing top board and the sliding friction pair coefficient of friction resistance that is embedded in the polyfluortetraethylene plate in the spherical crown steel liner plate greatly the end in the coefficient of friction resistance of dry friction slide surface, the bearing slippage is finished thus, the not slippage of dry friction face, and the damping shock absorption circle does not produce crimp yet.The 3rd, set up a sphere corrosion resistant plate at spherical crown steel liner plate spherical crown surface, form the sphere friction pair with the sphere polyfluortetraethylene plate, make bearing rotate inflexible drawback with the corrosion of eliminating because of the spherical crown steel liner plate.
See by described structure, the utility model has not only kept advantages such as protocorm shaped steel bearing bearing capacity is big, counter-force is even, rotating torque is little, building height is low, and, the utility model adopts bolt connecting mode with non-glide direction baffle plate of bearing and top board, make baffle plate change shearing-resistance blocks into, form earthquake resistant structure.When strong horizontal force is cut off shear-pin and bolt, earthquake resistant structure generation effectiveness.In addition, seismic isolation and reduction structure is set, promptly at energy dissipating plate in the setting of bearing concave surface steel liner plate soffit and place between the following energy dissipating plate on basin pelvic cavity surface, the end and formed a new dry friction slide surface, it can slippage under the earthquake horizontal force action as dry-friction damping, earthquake energy.Simultaneously, the damping shock absorption circle that is provided with on the bearing steel basin inner edge mouth can produce crimp after dry friction slide surface generation slippage, seismic energy can be discharged, and damping material has consumed seismic energy once more.So the utility model has antidetonation and energy-dissipating and shock-absorbing effect preferably when earthquake takes place, avoided earthquake disaster that structure such as bridge are done great damage.The used damping material of the utility model conveniently is easy to get, and damped ring and energy dissipating plate are all replaceable after the earthquake.The utility model uses when common ball shaped steel bearing when non-earthquake, but therefore peak clipping damping during earthquake can satisfy the requirement of the higher regional bridge engineering of the intensity of providing fortification against earthquakes to bearing.
