Description
Technical field
The invention belongs to Bridge Seismic technical field, particularly relate to a kind of U-shaped antivibrator bearing shock-damping structure.
Background technology
The shock-damping structure that bridge uses at present mainly has friction pendulum support, viscous damper, yielding rubber bearing etc..When, displacement the highest in earthquake shock is little, good cushioning effect can be played, it is adaptable to distant shock district.And for Earthquake Fault Zone near earthquake region, when earthquake occurs, earthquake shock is strong, displacement is very big, how the structural damping in such region is carried out, and becomes this skilled person's problem demanding prompt solution.
Summary of the invention
It is an object of the invention to provide a kind of U-shaped antivibrator bearing shock-damping structure, simple in construction, easy for installation, thus it is fully solved the problem that above-mentioned prior art exists.
The purpose of the present invention is realized by following technical proposals:
A kind of U-shaped antivibrator bearing shock-damping structure, including the bearing being arranged between beam body and pier, four sides of described bearing are mounted on U-shaped antivibrator, this antivibrator includes top connection and lower contact, upper lower contact is connected by U-shaped elastic component, and upper lower contact correspondence is connected with the upper base plate of bearing and lower seat board.
As preferably, described top connection, U-shaped elastic component and lower contact are one-body molded.
As preferably, described U-shaped antivibrator is steel.
As preferably, described bearing is one-way movable support or bi-directional movable bearing, up and down seat board with bearing corresponding to the upper lower contact of the U-shaped antivibrator of both sides along bridge is fixed and is connected, the top connection of the U-shaped antivibrator of direction across bridge both sides is plugged on the upper base plate of bearing, and lower contact is fixing with the lower seat board of bearing to be connected.
As preferably, described bearing is hold-down support, fixes at the seat board up and down with bearing all corresponding to the upper lower contact with direction across bridge U-shaped antivibrator along bridge and is connected.
As preferably, described U-shaped elastic component is horizontal positioned or vertical places or both combine placement.
In actual use, when antivibrator two ends produce displacement less time, U-shaped antivibrator is in elastic state, now can provide certain rigidity for structure.When the displacement of antivibrator two ends generation is bigger, antivibrator enters plasticity duty, and by bearing upper and lower seat board power transmission, the U-shaped antivibrator of both sides occurs bending and deformation, and displacement is the biggest, deforms the biggest.In deformation process, the U-shaped antivibrator of the left and right sides acts on simultaneously, will form the full hysteresis loop around starting point, it is achieved the power consumption to structure.
Compared with prior art, the beneficial effects of the present invention is: simple in construction, reasonable in design, easy to install and use, it is respectively provided with preferable damping effect under various earthquake intensities and under wind load.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
Embodiment one
As shown in Figures 1 to 5, a kind of U-shaped antivibrator bearing shock-damping structure, including the bearing being arranged between beam body and pier, four sides of described bearing are mounted on U-shaped antivibrator 1, this antivibrator 1 includes top connection 11 and lower contact 12, upper lower contact 11,12 is connected by U-shaped elastic component 13, and upper lower contact 11,12 correspondence is connected with the upper base plate 2 of bearing and lower seat board 3.
Described U-shaped antivibrator 1 is steel.Described top connection 11, U-shaped elastic component 13 and lower contact 12 are one-body molded.
Seeing Fig. 4 and Fig. 5, described U-shaped antivibrator 1 has two kinds of configurations, and the top connection 11 of the first U-shaped antivibrator is horizontal plate, and lower contact 12 is vertical plate, and top connection 11 is mutually perpendicular to lower contact 12；The upper lower contact 11,12 of the second U-shaped antivibrator 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 antivibrator is installed to both sides, the corresponding seat board up and down 2,3 with bearing of the upper lower contact 11,12 of antivibrator is bolted to connection, the second U-shaped antivibrator is installed in direction across bridge both sides, the top connection 11 of antivibrator 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.
Operation principle is as follows:
Under normal circumstances, realizing beam body by bearing the most spacing, U-shaped antivibrator is inoperative.When earthquake occurs, when earthquake horizontal force is more than the shear pin shear strength on bearing, shear pin is cut off, and bearing baffle plate comes off, and now, U-shaped antivibrator starts to play cushioning effect, it is achieved two-stage damping.
When antivibrator occurs less horizontal displacement (when wind load or small earthquake), U-shaped antivibrator, still in elastic state, provides certain rigidity for structure.When U-shaped antivibrator is when occurring greater level displacement (moderately strong earthquake), and portion of material enters non-resilient duty earthquake energy.Due to the restriction of the upper and lower seat board of bearing, limiting the vertical deflection of structure, the displacement of straightway in U-shaped antivibrator is generally radiused, thus the deformation of structure plays the effect of " soft-lock ".Therefore, this shock-damping structure is applicable to the energy-dissipating and shock-absorbing requirement under various earthquake intensity and wind load, and manufacture, install, very easy to use.
Embodiment two
See Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the present embodiment is with the difference of embodiment one, described bearing is bi-directional movable bearing, along bridge, the first U-shaped antivibrator is installed to both sides, the corresponding seat board up and down 2,3 with bearing of the upper lower contact 11,12 of antivibrator is bolted to connection, the second U-shaped antivibrator is installed in direction across bridge both sides, and the top connection 11 of antivibrator 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 present embodiment is with the difference of embodiment one, described bearing is hold-down support, is being respectively mounted the second U-shaped antivibrator along bridge to direction across bridge, and the corresponding seat board up and down 2,3 with bearing of the upper lower contact 11,12 of antivibrator is fixed and is connected.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
