Description
Technical field
The utility model belongs to Bridge Seismic technical field, particularly relates to a kind of U-shaped damper bearing shock-damping structure.
Background technology
The shock-damping structure that current bridge uses mainly contains friction pendulum support, viscous damper, yielding rubber bearing etc.When, displacement not high in earthquake shock is little, good cushioning effect can be played, be applicable to distant shock district.And for Earthquake Fault Zone near earthquake region, when earthquake occurs, earthquake shock is strong, displacement is very large, how the structural damping in such region carries out, and becomes this those skilled in the art's problem demanding prompt solution.
Utility model content
The purpose of this utility model is just to provide a kind of U-shaped damper bearing shock-damping structure, and structure is simple, easy for installation, thus solves above-mentioned prior art Problems existing completely.
The purpose of this utility model is realized by following technical proposals:
A kind of U-shaped damper bearing shock-damping structure, comprise the bearing be arranged between beam body and pier, four sides of described bearing are all provided with U-shaped damper, this damper comprises top connection and lower contact, upper lower contact is connected by U-shaped elastic component, and the corresponding upper base plate with bearing of upper lower contact and lower seat board are connected.
As preferably, described top connection, U-shaped elastic component and lower contact are one-body molded.
As preferably, described U-shaped damper is steel.
As preferably, described bearing is one-way movable support or bi-directional movable bearing, be fixedly connected with the seat board up and down of bearing along the upper lower contact correspondence of bridge to the U-shaped damper of both sides, the top connection of the U-shaped damper of direction across bridge both sides is plugged on the upper base plate of bearing, and lower contact is fixedly connected with the lower seat board of bearing.
As preferably, described bearing is fixed bearing, is being fixedly connected with to the upper lower contact of direction across bridge U-shaped damper is all corresponding along bridge with the seat board up and down of bearing.
As preferably, described U-shaped elastic component is horizontal positioned or vertically places or both combine placement.
In actual use, when the generation displacement of damper two ends is less, U-shaped damper is in elastic state, now can provide certain rigidity for structure.When the displacement of damper two ends generation is larger, damper enters plasticity duty, and by the upper and lower seat board power transmission of bearing, the U-shaped damper of both sides occurs bending and deformation, and displacement is larger, is out of shape larger.In deformation process, the U-shaped damper of the left and right sides acts on simultaneously, by forming the full hysteresis loop around starting point, realizes the power consumption to structure.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, reasonable in design, easy to install and use, under various earthquake intensity and wind carry under all there is good damping effect.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
Embodiment one
As shown in Figures 1 to 5, a kind of U-shaped damper bearing shock-damping structure, comprise the bearing be arranged between beam body and pier, four sides of described bearing are all provided with U-shaped damper 1, this damper 1 comprises top connection 11 and lower contact 12, upper lower contact 11,12 is connected by U-shaped elastic component 13, and the corresponding upper base plate 2 with bearing of upper lower contact 11,12 and lower seat board 3 are connected.
Described U-shaped damper 1 is steel.Described top connection 11, U-shaped elastic component 13 and lower contact 12 are one-body molded.
See Fig. 4 and Fig. 5, described U-shaped damper 1 has two kinds of structural forms, and the top connection 11 of the first U-shaped damper is level board, and lower contact 12 is vertical plate, and top connection 11 is mutually vertical with lower contact 12; The upper lower contact 11,12 of the second U-shaped damper is vertical plate, and their bottom surface is positioned on same perpendicular.
See Fig. 1 and Fig. 2, described bearing is one-way movable support, along bridge, the first U-shaped damper is installed to both sides, the upper lower contact 11,12 of damper is corresponding to be bolted to connection with the seat board up and down 2,3 of bearing, the second U-shaped damper is installed in direction across bridge both sides, the top connection 11 of damper is plugged on bottom the upper base plate 2 of bearing, and lower contact 12 is bolted to connection with the lower seat board 3 of bearing.
Operating principle is as follows:
Under normal circumstances, realize beam body by bearing normally spacing, U-shaped damper is inoperative.When earthquake occurs, when being greater than the shear pin shear strength on bearing when earthquake horizontal force, shear pin is cut off, and bearing baffle plate comes off, and now, U-shaped damper starts to play cushioning effect, realizes two-stage damping.
When less horizontal movement occurs damper when small earthquake (wind carry or), U-shaped damper is still in elastic state, for structure provides certain rigidity.When U-shaped damper is when larger horizontal movement occurs (moderately strong earthquake), portion of material enters non-resilient duty and earthquake energy.Due to the restriction of the upper and lower seat board of bearing, limit the vertical deflection of structure, the straightway displacement approximate circle arc in U-shaped damper, thus the distortion of structure is play a part " soft lock ".Therefore, this shock-damping structure be applicable to various earthquake intensity and wind carry under energy-dissipating and shock-absorbing requirement, and manufacture, install, very easy to use.
Embodiment two
See Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the difference of the present embodiment and embodiment one is, described bearing is bi-directional movable bearing, along bridge, the first U-shaped damper is installed to both sides, the upper lower contact 11,12 of damper is corresponding to be bolted to connection with the seat board up and down 2,3 of bearing, the second U-shaped damper is installed in direction across bridge both sides, and the top connection 11 of damper is plugged on bottom the upper base plate 2 of bearing, and lower contact 12 is bolted to connection with the lower seat board 3 of bearing.
Embodiment three
See Fig. 5, Fig. 8 and Fig. 9, the difference of the present embodiment and embodiment one is, described bearing is fixed bearing, is all installing the second U-shaped damper along bridge to direction across bridge, and upper lower contact 11,12 correspondence of damper is fixedly connected with the seat board up and down 2,3 of bearing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
