Description

A kind of adjustable damping shock-damping structure
Technical field
The utility model belongs to engineering structures Seismic Resistance And Disaster Reduction technical field; Relate to a kind of adjustable damping shock-damping structure specifically.
Background technology
Reinforced concrete structure adopts maximum a kind of structure typess in current China infrastructure project, its under geological process to collapse with destroying be the main reason of the casualties that causes of earthquake and property loss, the seismic design of concrete structure is under given fortification intensity, geological process is resisted by improving the performance of structure own, structural element size is strengthened as utilized, more high-strength material is adopted to increase the rigidity of structure, or store and consumed energy by the destruction of some component in structural system, but due to people can not the size of foreseeing earthquake load and characteristic in advance, and concrete structure does not possess the ability of carrying out self-control according to the size of geological process, once exceed seismic fortification intensity, structure under strong geological process even without collapsing, also larger damage and permanent set can be produced, structure function is caused to be lost, final structure can only be pushed over reconstruction, cause huge waste.
Summary of the invention
Goal of the invention of the present utility model:
Mainly in order to provide a kind of damping force automatically can identify according to geological process size, then the reinforced concrete structure of the adjustable damping shock absorption of the automatic adjustment of damping force is realized, thus reach damping and combat a natural disaster, guarantee the technique effect of people's property and life security.
The technical solution of the utility model is:
Provide a kind of adjustable damping shock-damping structure, comprise the cylinder of the top beam of reinforced concrete structure body, bottom beam and both sides, in the below of top beam, junction steel plate is provided with MR damper, the downside of MR damper is provided with the type steel support in isosceles trapezoid, MR damper is fixedly connected with by link with type steel support, two, the left and right of the type steel support of isosceles trapezoid, footing place is provided with Welded Plate joint, left and right Welded Plate joint respectively at left and right cylinder and bottom beam by being welded and fixed.
Bottom beam is also provided with sensor, the side of sensor is provided with controller, controller is interconnected respectively at sensor and MR damper by wire.
Described type steel support adopts hot-rolling H-shaped steel.
The beneficial effects of the utility model are:
This adjustable damping control structure is simply applicable; can according to the size of earthquake intensity and characteristic thereof by realizing the self-control of damping system after accurate Analysis of Vibration Reduction; thus the dynamic response of effective reduction structure under geological process; thus the safety of architecture protection structure under geological process to greatest extent, reduce the safety of life and property risk of the people.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure; 1 is cylinder; 2 is top beam; 3 is type steel support; 4 is link; 5 is MR damper; 6 is junction steel plate; 7 is Welded Plate joint; 8 is controller; 9 is sensor; 10 is wire; 11 is bottom beam.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, provide a kind of adjustable damping shock-damping structure, comprise the top beam 2 of reinforced concrete structure body, the cylinder 1 of bottom beam 11 and both sides, in the below of top beam, junction steel plate 6 is provided with MR damper 5, the type steel support 3 in isosceles trapezoid is provided with in the downside of MR damper 5, MR damper and type steel support fix 4 connections by link, two, the left and right of the type steel support of isosceles trapezoid, footing place is provided with Welded Plate joint 7, left and right Welded Plate joint 7 respectively at left and right cylinder 1 and bottom beam 11 by being welded and fixed, bottom beam is also provided with sensor 9, the side of sensor 9 is provided with controller 8, controller 8 is interconnected respectively at sensor 9 and MR damper 5 by wire 10, described type steel support adopts hot-rolling H-shaped steel, in the structure of this utility model, can not deformation be there is in hot rolled H-shaped support 3 when earthquake, and by relative storey displacement, speed and acceleration are converted to the displacement at MR damper 5 two ends, speed and acceleration, thus realize Structural Energy Dissipation shock-absorbing function, sensor 9 is connected with controller 8 by wire 10, the size of the seismic signal that controller 8 records according to sensor 9 and characteristic select suitable electric current, and be input in MR damper 5 by wire 10, thus change the size of damping force, and then realize the adjustable function of structure, this adjustable damping control structure is simply applicable, can according to the size of earthquake intensity and characteristic thereof by realizing the self-control of damping system after accurate Analysis of Vibration Reduction, thus the dynamic response of effective reduction structure under geological process, thus the safety of architecture protection structure under geological process to greatest extent, reduce the safety of life and property risk of the people.
