Abstract
The invention discloses a bridge damping structure which comprises an upper box plate.At least two damping insertion plates are vertically mounted at a position, close to the middle, of the lower surface of the upper box plate, the bottom of each damping insertion plate is connected with the upper box plate and positioned on a buffering platform, a protecting frame coats the outer side of each damping insertion plate, a reinforcing plate is arranged between the outer side of each protecting frame and the corresponding buffering platform and fixed on the corresponding protecting frame and the corresponding buffering platform respectively, each protecting frame is embedded in the corresponding buffering platform, the bottom of each buffering platform is positioned on a lower box plate, and the lower box plate and the buffering platforms are connected through internally-arranged reinforcing screws.The bridge damping structure is firm in connection, high in reliability, low in manufacturing cost and quite convenient to mount and replace, a need on one-way free sliding in a daily working state and a need on damping in a damping direction under seismic load action are meet, and reduction in damping effect caused by changing of gaps among the damping insertion plates during working can be avoided.
Description
Technical field
The present invention relates to a kind of damping structure, particularly to a kind of bridge damping structure.
Background technology
Bridge is as an important social infrastructure, have the advantages that investment is big, public character is strong, maintenance management is difficult, bridge is again an important component part in Seismic Resistance And Disaster Reduction management system simultaneously, and the anti-seismic performance improving bridge is one of seismic losses mitigation, the reinforced region most important basic measures of safety. Reality often has the generation of the natures such as earthquake or human accident, therefore, the structural performance requirements of bridge self is more and more higher, especially anti-seismic performance, reduce the factor such as earthquake to the broken meeting of these engineerings, improve engineering service life, be that there is very real meaning.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, it is provided that the bridge damping structure that a kind of self structure connectivity is firm, reliability is high.
To achieve these goals, the technical solution used in the present invention is such that the bridge damping structure of the present invention, including upper boxboard, upper boxboard lower surface is vertically provided with damping plate near middle part, damping plate at least two, it is connected with upper boxboard bottom it, it is positioned on a buffer table bottom it, it is coated with protective frame outside damping plate, reinforcement plate it is provided with outside protective frame and between buffer table, strengthen plate and be separately fixed on protective frame and buffer table, protective frame embeds and is arranged in buffer table, it is positioned on boxboard bottom buffer table, lower it is connected by built-in reinforcement screw between boxboard with buffer table, lower boxboard is equipped with reinforcement near buffer table both sides place, it is connected with lower boxboard bottom reinforcement, its top is connected through lower boxboard with buffer table.
Further, as a kind of concrete version, four drift angle places, upper boxboard top of the present invention are equipped with connecting hole.
Further, as a kind of concrete version, bottom lower boxboard of the present invention, four base angles place is equipped with connecting hole.
Further, as a kind of concrete version, the height of protective frame of the present invention is less than the height of damping plate.
Further, as a kind of concrete version, lower boxboard lower surface of the present invention is provided with antiskid plate, and antiskid plate is pasted onto on lower boxboard.
Further, as a kind of concrete version, buffer table of the present invention is trapezoidal-structure.
Further, as a kind of concrete version, inside reinforcement plate of the present invention and between protective frame, form right-angle structure.
Compared with prior art, it is an advantage of the current invention that: the bridge damping structure self structure connectivity of the present invention is firm, reliability is high, low cost of manufacture, installation and change all very convenient, not only meet the unidirectional free sliding of routine work state, meet the damping damping direction under seismic (seismal effect simultaneously and subtract shock insulation needs, can better guarantee that the gap between damping plate will not change in work process and reduce damping effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the present invention; In figure: 1. go up boxboard; 2. damping plate; 3. protective frame; 4. strengthen plate; 5. buffer table; 6. descend boxboard; 7. reinforcement.
Detailed description of the invention
