Description
Technical field
The utility model belongs to long strands field, and in particular to a kind of steel structure earthquake-resistant bearing.
Background technology
The structure that steel construction is made up of steel material, is one of main building construction types.Structure is main by shaped steel
With the component composition such as the girder steel, steel column, the steel truss that are made such as steel plate, between each component or part generally using weld seam, bolt or
Rivet interlacement, because its deadweight is lighter, and easy construction, it is widely used in the fields such as large-sized workshop, venue, Super High.
Earthquake be also known as earthquake, vibrate, be that vibration is caused during earth's crust quick release of energy, during which can produce seismic wave
A kind of natural phenomena.Mutual extrusion and collision between plate and plate on the earth, causes edge of plate and plate interiors to produce wrong
Dynamic and rupture, is the main cause for causing earthquake.According to statistics, it is annual on the earth about to occur more than 500 ten thousand secondary earthquakes, i.e., to send out daily
The earthquake of raw up to ten thousand times.Current scientific and technological level there is no the arrival of method prediction earthquake, following interior for quite a long time, earthquake
It is also unpredictable.
For earthquake, what we should more do is to improve building aseismicity grade, carry out defence.Existing steel construction is usually used
Bearing sets anti-seismic material to improve the anti seismic efficiency of steel construction as connecting elements, and in bearing, and anti-seismic material is generally
Rubber blanket or spring, can only play certain anti seismic efficiency, for strong earthquakes, vibration pole of the steel construction in horizontally and vertically direction
Fragile anti-seismic material, so as to cause steel construction to damage, shortens the service life of steel construction.
Utility model content
The purpose of this utility model is：The problem of for above-mentioned existing steel structure earthquake-resistant effect difference, the utility model is carried
For a kind of steel structure earthquake-resistant bearing.
The technical solution adopted in the utility model is as follows：
A kind of steel structure earthquake-resistant bearing, including steel construction supporting leg, the bottom of the steel construction supporting leg are connected with supporting plate, institute
The bottom for stating supporting plate is connected with quake-proof seat, and the quake-proof seat is to be set in groove A, the groove A that opening upwards are set
There is the first damping device, first damping device includes the pressure-bearing rubber block for being fixed on groove A bottoms, the pressure-bearing rubber block
Two ends be arranged with first through hole, first through hole the first elastic component be installed, the middle part of the pressure-bearing rubber block is provided with the
The connecting plate that is provided with and can be rotated around support bar at the top of support bar, the support bar is installed, even in two through holes, the second through hole
The two ends of fishplate bar are connected with the first elastic component respectively, and one end of connecting plate is connected with the supporting plate by support column, the branch
Dagger, to be slidably connected, is provided with the second elastic component with connecting plate between the inwall of the support column and quake-proof seat.

When steel construction vibrates in the horizontal direction, due to support column with connecting plate to be slidably connected, therefore, supporting plate drives support column to exist
Moved in horizontal direction, the second elastic component of support column side is stretched and rebounded, the second elastic component of support column opposite side
Compressed and rebounded, can reach damping effect.
The connecting plate and the upper surface of support column connection end are provided with groove B, and the bottom of the support column is connected with friction
Piece, friction plate is to be slidably connected with groove B.Can open up groove in the side of connecting plate, and friction plate side connection with it is recessed
The L-type plate of groove cooperation simultaneously makes L-type plate be slidably connected with groove clamping to realize.When earthquake causes steel construction to shake in the horizontal direction
When dynamic, supporting plate drives support column to move in the horizontal direction, so that friction plate is slided in groove B, is consumed by friction plate
Energy can further damping.In addition, the vibration on the further buffer level direction of rubber layer can be set in groove B side wall.Meanwhile,
Groove B side wall can be spacing to the mobile carry out of steel construction in the horizontal direction, it is to avoid the second elastic component is damaged.
The junction of the supporting plate and quake-proof seat is provided with the second damping device, can further improve damping effect.
Second damping device includes rubber layer, steel plate layer and the rubber layer set gradually from top to bottom.By ground
During shake, supporting plate and the rubber layer of quake-proof seat junction can aid in the first damping device, and the vibration on vertical direction is played
Further cushioning effect, and steel plate layer can make the second damping device bear larger impact.
Positive stop is arranged with quake-proof seat inwall above the connecting plate, positive stop can be to connecting plate perpendicular
The upward mobile carry out of Nogata is spacing so that steel construction because connecting plate around support bar rotate and caused by angle of inclination be limited in one
Individual less scope, it is to avoid steel construction because angle of inclination is excessive and to the first damping device caused by catastrophic collapse.
First elastic component and the second elastic component are spring.
The quake-proof seat is fixed on building foundation by anchorage screw.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. there is provided a kind of steel structure earthquake-resistant bearing, the first damping device is set inside the bearing, by can be around support bar
The connecting plate of rotation realizes the first elastic component and pressure-bearing rubber block and coordinates damping, so as to be shaken to steel construction in the vertical direction
It is dynamic to play buffering effect, and buffering is played to the vibration of steel construction in the horizontal direction by the second elastic component and friction plate power consumption
Effect, so as to reach the purpose of antidetonation；
2. by setting the second damping device in the junction of supporting plate and quake-proof seat, further improve damping effect；
3. the first elastic component of the present utility model and the second elastic component are protected by pressure-bearing rubber block and groove B respectively,
Its stretching is set, not over elastic range, to increase the service life with compression；
4. simple in construction, anti seismic efficiency of the present utility model is good, and is hardly damaged, with stronger practicality.
