Description
Technical field
The invention belongs to building beam column connection area more particularly to a kind of damping shock absorption beams.
Background technique
Steel building have intensity it is high, from heavy and light, speed of application is fast, anti-seismic performance is good and the spies such as industrialization degree height
Point.Steel structure member by connecting node composed structure system, the selection of joint form for structural integrity, reliability, build
If period and Accessory Members design and construction have direct influence.In modern factories, the equipment of some large sizes needs to fix
On the crossbeam of steel construction, and the gravity of equipment itself and equipment operation make generated vibration, and crossbeam mode can be made to be bent,
And common beam-to-column joint structure, crossbeam both ends are all to fix on the support columns, thus generate stress at crossbeam both ends and concentrate, and are held
It is easily that the junction of crossbeam and support column is broken, it is therefore desirable to which a kind of beam column shock-absorption connecting structure, can in crossbeam bend
It is concentrated with reducing the stress at both ends, prevents from being broken.
Summary of the invention
In order to solve the above technical problems, can solve prior art beam column company the present invention provides a kind of damping shock absorption beam
It connects crisis and is easy the problems in stress collection.
The present invention is achieved by the following technical programs.
A kind of damping shock absorption beam provided by the invention, including support column, crossbeam, damper, the crossbeam both ends are equipped with recessed
Slot, groove is interior to be equipped with connecting shaft A, and connecting shaft A is connect by link block with the connecting shaft B in support column, and the link block is in L
Type, link block middle part are connect with connecting shaft B, and link block one end and crossbeam are hinged, and described damper one end and support are column articulated, resistance
Buddhist nun's device other end and link block one end are hinged.
There are four the damper is total, set on every support column there are two damper, damper is separately positioned on link block
Upper and lower two sides, two damper one end are column articulated with support, and two damper other ends pass through connector and link block is cut with scissors
It connects.
The connector includes that hinged block A, hinged block B, the hinged block A and hinged block B are interconnected by connecting shaft B phase
It connects, and hinged block A and hinged block B are connect with damper respectively.
The angle of the damper and link block is 75 ° to 85 °, the angle phase of the damper and link block of upper and lower two sides
Deng.
The damper is viscous damper.
Gap between the crossbeam two sides and support column is 2cm to 4cm.
The link block vertical extension is the 1/2 to 1/3 of its lateral length.
The beneficial effects of the present invention are: by the way that link block is arranged between crossbeam and support column, in crossbeam swing process
In, by link block band fluctuation dampers, reduce the vibration of equipment by damper, while being bent by external force in crossbeam
When, crossbeam both ends can rotate, and prevent stress from concentrating at crossbeam both ends, improve the service life of building.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1 to Figure 3, a kind of damping shock absorption beam, including support column 1, crossbeam 2, damper 7,2 both ends of crossbeam
Equipped with groove 4, connecting shaft A5 is equipped in groove 4, connecting shaft A5 is connect by link block 3 with the connecting shaft B6 in support column 1, institute
It is L-shaped to state link block 3,3 middle part of link block is connect with connecting shaft B6, and 3 one end of link block and crossbeam 2 are hinged, the damper 7 one
End is hinged with support column 1, and 7 other end of damper and 3 one end of link block are hinged.
When equipment is mounted on crossbeam 2, crossbeam 2 is affected by gravity, and is bent, due to 2 both ends of crossbeam and company
It is hinged to connect block 3, after bending in the middle part of crossbeam 2,2 both ends of crossbeam can rotate, and crossbeam 2 and the junction of support column 1 go out
Existing stress is concentrated, and the stability and physical life of steel construction are improved, and when swinging in equipment operation, crossbeam 2 drives L-type to connect
The rotation of block 3 is connect, since 3 end of link block is connect by damper 7 with support column 1, during the swing, passes through damper 7
Viscous effect, eliminates the energy of swing, to reduce vibration.
The damper 7 altogether there are four, set on every support column 1 there are two damper 7,7 company of being separately positioned on of damper
Connect about 3 two sides of block, two 7 one end of damper are hinged with support column 1, two 7 other ends of damper pass through connector 8 with
Link block 3 is hinged, will drive L-type link block 3 when crossbeam 2 is swung and rotates, and two dampers 7 are from upper and lower two sides and link block 3
End connection, in 3 rotation process of link block, damper 7 stretches simultaneously, by the hydraulic oil and spring in damper 7,
Thermal energy is converted by the kinetic energy of swing, to reduce vibration.
As shown in figure 3, the connector 8 is logical including hinged block A9, hinged block B10, the hinged block A9 and hinged block B10
Connecting shaft B11 interconnection is crossed, and hinged block A9 and hinged block B10 are connect with damper 7 respectively, make two by connector 8
Damper 7 and link block 3 are connected with each other, and when crossbeam 2 is swung, 2 both ends of crossbeam pass through link block 3 and connect with damper 7, are led to
The collective effect for crossing four dampers 7, eliminates the energy of swing, to reduce vibration.
The angle of the damper 7 and link block 3 is 75 ° to 85 °, the damper 7 of upper and lower two sides and the angle of link block 3
Equal, when link block 3 rotates, about close to vertical, the stretching speed of damper 7 is bigger for damper 7 and the angle of link block 3,
The viscous effect of damper 7 is also bigger, and the damper 7 of upper and lower two sides is equal with the angle of link block 3, when crossbeam 2 is swung, resistance
The flexible stroke of Buddhist nun's device 7 is identical, is easy to use the damper 7 of same model.
The damper 7 is viscous damper, and viscous damper is mutual using resisting medium and damper structure component
The principle that effect generates damping force converts thermal energy for the kinetic energy of swing when damper 7 stretches, to quickly reduce pendulum
Dynamic amplitude reduces harm of the vibration equipment to steel building.
Gap between 2 two sides of crossbeam and support column 1 is 2cm to 4cm, be free to crossbeam 2 in support column 1
It swings.
3 vertical extension of link block is the 1/2 to 1/3 of its lateral length, will by link block 3 when crossbeam 2 is swung
Its Amplitude amplification so that the distance of stretch out and draw back of damper 7 be made to become larger, therefore only needs to select the lesser damper 7 of specification, and saving is set
Standby cost.
