Description
Technical field
The utility model relates to a kind of shock-insulation building damper, and the utility model especially relates to a kind of from spacing multiaspect drag-resisting frcition damper.
Background technique
At present, the damper being widely used in shock-insulation building has: U-shaped damper, annular rod iron damper, oil damper and frcition damper etc.And existing frcition damper has more shortcomings such as frictional force is easily lost, resistance to tension is weak, can only unidirectionally be out of shape.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provide a kind of can planar all directions larger friction damping force is provided and have limit function and certain vertical resistance to tension from spacing multiaspect drag-resisting frcition damper.
According to the technological scheme that the utility model provides, described from spacing multiaspect drag-resisting frcition damper, it comprises precompressed bolt, upper junction plate, upper friction plate, rigid link, middle friction plate and lower friction plate, friction plate in being provided with above lower friction plate, above middle friction plate, be provided with friction plate, above upper friction plate, be provided with upper junction plate; Upper friction plate offers upper limit through hole, upper junction plate and middle friction plate are fixed as one by some rigid link, the number of rigid link coordinates with the number of upper limit through hole, every root rigid link is through the upper limit through hole described in, upper friction plate and lower friction plate are fixed by precompressed bolt, and precompressed bolt applies pretightening force to upper friction plate, middle friction plate and lower friction plate.
Described upper limit through hole is circular port or slotted eye.
Described upper junction plate offers attachment hole.
The utility model planar all directions can not only provide larger friction damping force, also has limit function and certain vertical resistance to tension; The utility model has the advantages such as structure is simple, compact, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Should from spacing multiaspect drag-resisting frcition damper, it comprises precompressed bolt 1, upper junction plate 2, upper friction plate 3, rigid link 4, middle friction plate 5 and lower friction plate 6, friction plate 5 in being provided with above lower friction plate 6, above middle friction plate 5, be provided with friction plate 3, above upper friction plate 3, be provided with upper junction plate 2; Upper friction plate 3 offers upper limit through hole 3.1, upper junction plate 2 and middle friction plate 5 are fixed as one by some rigid link 4, the number of rigid link 4 coordinates with the number of upper limit through hole 3.1, every root rigid link 4 is through the upper limit through hole 3.1 described in, upper friction plate 3 is fixed by precompressed bolt 1 with lower friction plate 6, and upper friction plate 3 given by precompressed bolt 1, middle friction plate 5 applies pretightening force with lower friction plate 6.
Described upper limit through hole 3.1 is circular port or slotted eye.
Described upper junction plate 2 offers attachment hole 2.1.
The utility model is compressed by precompressed bolt 1 and provides pretightening force, and the size of precompressed bolt 1 and pressure damping force as required and vertical stretching resistance determine.
During use, upper junction plate 2 and superstructure bolt anchoring, lower friction plate 6 is fixed on the cushion cap of bottom, when bottom cushion cap and superstructure have relative displacement, there is relative sliding with upper friction plate 3 and lower friction plate 6 in middle friction plate 5, thus produces friction damping force.
Because upper limit through hole 3.1 is circular or oval, the distortion of different direction therefore can be met; When Seismic Isolation of Isolation Layer displacement is less than the radius of upper limit through hole 3.1, damper can be free to slide, and when Seismic Isolation of Isolation Layer displacement is excessive, the edge of upper limit through hole 3.1 can stop that rigid link 4 continues motion, thus plays limit effect.
By reference to the accompanying drawings the utility model embodiment is illustrated above; but the utility model is not limited to above-described embodiment; multiple change can also be made according to the object of innovation and creation of the present utility model; change, the modification made under all Spirit Essences according to technical solutions of the utility model and principle, substitute, combination, to simplify; all should be the substitute mode of equivalence; as long as meet goal of the invention of the present utility model; only otherwise deviate from know-why and the inventive concept of the utility model frcition damper, protection domain of the present utility model is all belonged to.
