Technical field
A kind of a kind of the utility model bridge three-dimensional seismic isolation device, and in particular to bridge three-dimensional seismic isolation device.
Background technique
Bridge belongs to the structure of typical " top-heavy ", is subject to damage when coming earthquake, to rescue after shake and
The unimpeded of channel brings very big influence after calamity.Anti-seismic technology is widely applied in low intensity in quake zone, but in high-intensity earthquake
Area is general relatively reasonable using seismic isolation technology is subtracted by design courses, the limit value of technological means.Theory analysis and earthquake warp
It tests and shows high intensity Zone, in addition to horizontal earthquake will cause the serious destruction of works, vertical seismic action will also result in fearful
Disaster, when Bridge Earthquake Resistance Design is also considered as the effect of vertical seismic action.
Current bridge seismic isolation device relatively mostly uses damper, vibration absorption and isolation support etc., and damper can only solve a side
To Seismic Problems, to solve horizontally damping generally need to be arranged two orthogonal dampers, and vibration absorption and isolation support is general
Both direction can be solved the problems, such as simultaneously.Obviously, if to solve two horizontal directions (along bridge to, direction across bridge) and one simultaneously
The earthquake of vertical direction, depends damper alone and vibration absorption and isolation support is also extremely limited, need to consider further that setting other measures to solve to erect
To subtracting shock insulation problem.The pier top for resulting in script spatial position very nervous in this way is arranged vertically that subtract isolation measure just more tired again
Difficulty, and economic cost increases.
Exploitation, which designs a kind of three-dimensional for being not only able to satisfy horizontal earthquake requirement and being able to satisfy vertical seismic action demand and subtracts shock insulation, to be filled
It sets and is just seemed very necessary applied to the bridge of high intensity Zone.
Summary of the invention
The purpose of the utility model is to provide a kind of bridge three-dimensional seismic isolation devices, are set to pier top and bridge top
Connecting portion, while solving the problems, such as to subtract shock insulation to, direction across bridge and vertical three directions along bridge, structural earthquake carrys out interim stress
Demand.
The technology employed by the present utility model is
A kind of bridge three-dimensional seismic isolation device, it is characterised in that:
It from bottom to top include built-in fitting, tenon body and pressing plate；
Built-in fitting defaults in pier top, and the ring flange and tenon body bottom being arranged at the top of built-in fitting by pier top surface are fixed to be connected
It connects；
Tenon body is in the form of a column, and beam body is inserted on top, and top is fixed in the empty van of beam body by pressing plate.
Tenon body top has external screw thread, is fixed by realizing with the pressing plate bolt with screw hole.
It is cased with rubber block outside part in tenon body insertion beam body empty van, pressing plate is located at rubber block top.
Vertical preformed hole is prefabricated in beam body, beam body is inserted by preformed hole in tenon body top.
Tenon body and pressing plate are mild steel material.
Built-in fitting is structure steel material.
Built-in fitting is reinforcing bar or bolt, and top has external screw thread, is fixedly connected with ring flange by bolt mode.
Tenon body bottom is fixedly attached to ring flange upper surface by welding manner.
Tenon body is inserted into from flat of bottom in beam body empty van, and rubber block is the casing that cross section is circular ring shape.
Tenon body from beam body empty van inner chamfer partial insertion, rubber block be the casing that cross section is circular ring shape, bottom surface and chamfering
It is close to be in inclined-plane in face.
The utility model has the advantage that
By the way that the three-dimensional seismic isolation device of the utility model is arranged between pier top and beam body, level side is solved using tenon body
Subtract shock insulation problem to (along bridge to, direction across bridge), solves the problems, such as vertically to subtract shock insulation using the connection of pressing plate and tenon body, solve simultaneously
The seismic isolation design problem in three directions of bridge, saves pier top space, facilitates constructing operation, reduce project cost.
Detailed description of the invention
Fig. 1 is setting three-dimensional seismic isolation device bridge pier and beam body direction across bridge figure.
Fig. 2 be arranged three-dimensional seismic isolation device bridge pier and beam body along bridge to figure.
In figure, 1, built-in fitting, 2, tenon body, 3, preformed hole, 4, pressing plate, 5, beam body, 6, rubber block, 7, pier top.
Specific embodiment
The utility model is described in detail With reference to embodiment.
The utility model relates to a kind of bridge three-dimensional seismic isolation devices, are set to the interconnecting piece of pier top 7 Yu bridge top
Position, while solving the problems, such as to subtract shock insulation, the interim stress demand of structural earthquake to, direction across bridge and vertical three directions along bridge.
The utility model includes built-in fitting 1, tenon body 2 and pressing plate 4 from bottom to top, and tenon body 2 and pressing plate 4 are mild steel material, in advance
Embedded part 1 is structure steel material.
Built-in fitting 1 defaults in pier top 7, ring flange and 2 bottom of tenon body at the top of built-in fitting 1 by the setting of 7 surface of pier top
It is fixedly connected.Built-in fitting 1 is reinforcing bar or bolt, and top has external screw thread, is fixedly connected with ring flange by bolt mode.Tenon body
