Specific embodiment
The present invention will be further described with attached drawing combined with specific embodiments below, to help the contents of the present invention are understood.
As shown in figures 1-8, the compound damping wall of steel plate friction, including it is frame beam column 1, upper head plate 7, bottom plate, anti-buckling
Steel plate and frcition damper.
Wherein frame beam column 1, clamping plate 3 and embedded steel plate 2 are the prior art in the compound damping wall of steel plate friction, herein
It does not repeat them here.
The upper head plate 7 and the bottom plate are plate, are oppositely arranged and are fixed on frame by high-strength bolt 9 respectively
On beam column 1.The anti-buckling steel plate includes that embedded steel plate 2, clamping plate 3 and guide channel plate 4, the embedded steel plate 2 are welded on described
Between end plate 7 and the bottom plate, and it is orthogonal with the two；2 two sides of embedded steel plate are respectively arranged with clamping plate 3, institute
The middle section setting notch of the top and bottom of clamping plate 3 is stated, wherein the upper end of the clamping plate 3 and upper head plate 7 weld, the folder
The lower end of plate 3 is not contacted with bottom plate, forms free end；There is polytetrafluoroethylene (PTFE) profit between the embedded steel plate 2 and the clamping plate 3
Lubrication prescription.
Guide channel plate 4 is fixed on the bottom plate, for limiting the face outer displacement of 3 free end of clamping plate.The guide groove
The cross section of plate 4 is square, and two right-angle sides are contacted with bottom plate and clamping plate 3 respectively, and the quantity of guide channel plate 4 is four, point
It is not symmetricly set on two clamping plates, 3 outside, and is fixed by welding.Anti-buckling steel plate is arranged in the upper head plate 7 and institute
It states between bottom plate, and orthogonal with the two.
The frcition damper includes L-type steel plate 5, T-steel plate 6 and friction plate 8；6 upper end of T-steel plate passes through high-strength
Bolt 9 is fixed on 7 lower surface of upper head plate；L-type steel plate 5 is two and is separately positioned on the two sides of T-steel plate 6, under T-steel plate 6
End and the upper end of L-type steel plate 5 are overlapped, and are additionally provided with friction plate 8 between two faying surfaces.The lower end of the T-steel plate 6 is provided with
Horizontal sliding slot；The L-type steel plate 5 and the friction plate 8 have bolt hole, pass through sliding slot and bolt hole for T with high-strength bolt 9
Shape steel plate 6, L-type steel plate 5 and friction plate 8 link together.Therefore T-steel plate 6 and L-type steel plate 5 in the horizontal direction being capable of phases
It is relatively fixed to mobile position in the other direction.The frcition damper is fixed between upper head plate 7 and bottom plate.
Each component erection sequence of the compound damping wall of steel plate friction provided by the invention is as follows:
Refering to attached drawing 2-3, the embedded steel plate 2 is welded with the upper head plate 7 and bottom plate first, coats polytetrafluoroethylene (PTFE)
After lubricant, in the fixed upper two clamping plates 3 in both ends, and 3 upper end of two clamping plates and the upper head plate 7 are welded.
Further, refering to attached drawing 4, upper guide groove plate 4 is welded on bottom plate, limits the lower free end of the clamping plate 3
Face outer displacement.
Further, refering to attached drawing 5-6, the L-type steel plate 5 in two pieces of strap bolt holes is bolt-connected to and is provided with bolt hole
Bottom plate on, equally the T-steel plate 6 with sliding slot is bolt-connected on the upper head plate 7 for being provided with bolt hole.
Further, refering to attached drawing 7, the friction plate 8 in strap bolt hole is inserted between L-type steel plate 5 and T-steel plate 6, with height
Strength bolt 9 connects the hole slot between two blocks of L-type steel plates 5 and T-steel plate 6 and friction plate 8, and pretightning force group is arranged using torque wrench
Synthesize the frcition damper.
Further, it refering to attached drawing 8, finally will integrally be bolted on the frame beam column 1.
The working principle of the compound damping wall of steel plate friction are as follows: high-strength bolt 9 first on adjusting frcition damper
Pretightning force makes it play the yield force that sliding power is less than embedded steel plate 2.The compound damping wall of steel plate friction starts in the first energy consumption stage
In the stage, upper head plate 7 is horizontal mobile in the same direction with T-type plate and embedded steel plate 2, and frcition damper only occurs flexible deformation, not yet rises
It is sliding.Steel plate 2 is embedded at this time, and lesser flexible deformation is occurred by transverse shearing force effect；Continue load deflection, is displaced when having reached sliding
When x1, axle power suffered by frcition damper reaches the maximum static friction force under the setting of 9 pretightning force of high-strength bolt, and static friction becomes dynamic and rubs
It wipes, the beginning of high-strength bolt 9 slides in the sliding slot of T-steel plate 6, embeds steel plate 2 at this time and continues to be cut deformation, but does not reach yet
To surrender.Continue load deflection, when displacement reaches x2, the compound damping wall of steel plate friction entered for the second energy consumption stage, at this time
Embedded steel plate 2 is cut surrender, starts to be plastically deformed, and start to consume energy, and frcition damper is still in lasting slip state, and interior
Embedding 2 shared of steel plate energy consumption work is until reach displacement amplitude x3.
It is moderate that the compound damping wall of steel plate friction of the invention adds a rigidity on the basis of anti-buckling steel plate, plays consumption
The lesser frcition damper of Displacement Ratio, forms the damping unit of a two steps type, and when can effectively solve small shake, anti-buckling steel plate is cut
The shortcomings that power wall can not consume energy.Notch is arranged in the middle section of the top and bottom of the clamping plate 3, and it is compound to reduce steel plate friction
The self weight of type damping wall.The compound damping wall of steel plate friction can be made accordingly according to the randomness and earthquake size of earthquake
Self-control.
Specific case used herein elaborates inventive concept, the explanation of above example is only intended to
Help understands core of the invention thought.It should be pointed out that for those skilled in the art, not departing from this
Under the premise of inventive concept, any obvious modification, equivalent replacement or the other improvements made should be included in the present invention
Protection scope within.
