Description
Technical field
The invention belongs to bridge technology field, particularly relate to the horizontal elastic damping device of a kind of bridge.
Background technology
At present, the extra-large bridge of floating or half floating system, bridge span is often very large, very large horizontal movement can be there is in beam body under vehicle, wind such as to carry at the live loading, and existing highway bridge is generally the vertical force adopting vertical support carrier bar body, when beam body bears larger horizontal movement under temperature, live loading time, vertical force bearing cannot play return action, therefore, the horizontal movement how utilizing bridge attachment device large horizontal rigidity control bridge mobile load to cause becomes the direction that these those skilled in the art make great efforts.
Summary of the invention
Object of the present invention is just to provide the horizontal elastic damping device of a kind of bridge, the beam body horizontal rigidity controlling the displacement of beam body mobile load can be converted to vertical rigidity, thus solve the problem of the horizontal insufficient rigidity of bridge.
Object of the present invention is realized by following technical proposals:
The horizontal elastic damping device of a kind of bridge, comprise wedge type block, lower wedge type block, Vertical Spring, Compact Mounts and base, be slidably matched by trapezoidal faces or inverted trapezoidal face between upper wedge type block and lower wedge type block, lower Vertical Spring and the Compact Mounts of being connected between wedge type block and base.
As preferably, there is multipair wedge type block group, wedge type block group is made up of a upper wedge type block and a lower wedge type block, and all upper wedge type blocks and all lower wedge type blocks connect as a whole separately, and the slide plane of multipair wedge type block group is trapezoidal faces, inverted trapezoidal face is arranged alternately.
This structure is conducive to this damping unit balance and bears horizontal load, when a horizontal load is applied to beam body time, slide plane due to each pair of wedge type block group is trapezoidal faces, inverted trapezoidal face is arranged alternately, therefore this damping unit can bear symmetrical vertical force, thus guarantee force balance, avoid unbalance loading occurs.
As preferably, described Vertical Spring be in rubber spring, metal spring or rubber-metal cluster spring any one.
As preferably, described Vertical Spring is vertically alternately socketed to form by outer toroid and interior annulus, and the fitting face between outer toroid and interior annulus is taper seat.
When Vertical Spring bears axial load, interior annulus reduced by compression, outer toroid Tensile and enlarged-diameter, interior annulus and outer toroid produce axial deformation along taper seat relative sliding thus play spring action, are particularly suitable for the situation that rigidity is large, structure is little.
As preferably, described Compact Mounts comprises vertical guiding steel pipe and horizontal shear pin, and vertical guiding steel pipe is fixed on base, and horizontal shear pin one end is fixed on bottom lower wedge type block, and the other end inserts in vertical guiding steel pipe.
As preferably, described Compact Mounts is horizontal baffle, and this horizontal baffle is fixed on base, and symmetry is connected in lower face, wedge type block left and right or front-back.
Compared with prior art, beneficial effect of the present invention is: structure is simple, reasonable in design, the horizontal force that beam body is subject to can be converted to vertical force, thus realize beam body horizontal Large travel range motion be converted to vertical thin tail sheep motion, beam body horizontal damping rigidity is converted into vertical damping rigidity, avoids the horizontal movement of beam body excessive.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
Embodiment one
As depicted in figs. 1 and 2, the horizontal elastic damping device of a kind of bridge, comprise wedge type block 1, lower wedge type block 2, Vertical Spring, Compact Mounts and base, a upper wedge type block 1 and a lower wedge type block 2 form a pair wedge type block group, be slidably matched by trapezoidal faces or inverted trapezoidal face between upper wedge type block 1 and lower wedge type block 2, multipair wedge type block group is arranged side by side, and the face of being slidably matched be trapezoidal faces, inverted trapezoidal face is arranged alternately, it is one overall that all upper wedge type blocks 1 and lower wedge type block 2 are connected separately by bolt.Described Vertical Spring is connected between lower wedge type block 2 and base 3, and this Vertical Spring is alternately socketed to form by outer toroid 4 and the vertical overlap of interior annulus 5, and the fitting face between outer toroid 4 and interior annulus 5 is taper seat.Described Compact Mounts comprises vertical guiding steel pipe 6 and horizontal shear pin 7, and vertical guiding steel pipe 6 is placed in Vertical Spring and fixes on the base 3, and horizontal shear pin 7 one end is fixed on bottom lower wedge type block 2, and the other end inserts in vertical guiding steel pipe 6.
Above-mentioned Vertical Spring also can adopt other springs such as rubber spring, metal spring or rubber-metal cluster spring to replace.
Horizontal force can be converted to vertical force by this damping unit, utilizes beam body to conduct oneself with dignity and forms horizontal rigidity.When bridge beam body horizontal movement, the horizontal force that beam body is subject to passes to lower wedge type block 2 by upper wedge type block 1, same wedge type block 2 horizontal direction is at present fixed by Compact Mounts, beam body drives upper wedge 1 to move upward along the face of being slidably matched with lower wedge type block 2, under beam body Action of Gravity Field, lower wedge type block 2 compresses Vertical Spring, Vertical Spring produces vertical counter-force, form the horizontal damping to beam body by the trapezoidal fitting face between upper and lower wedge type block 1,2, thus beam body horizontal rigidity is converted to vertical rigidity.Horizontal force is effectively passed to pier below by horizontal shear pin 7.
This damping unit can use jointly with common vertical support, and when beam body is without horizontal movement, damping unit does not produce vertical counter-force, and namely without horizontal resistance, beam body vertical force is all born by vertical support.When the horizontal movement of beam body, this damping unit produces vertical counter-force, and now beam body vertical load is born jointly by vertical support and damping unit.Because this damping unit produces vertical counter-force, then produce horizontal resistance, its horizontal resistance size increases with the increase of displacement, but maximum vertical counter-force is no more than vertical support simultaneously.
Embodiment two
As shown in Figure 3, the difference of the present embodiment and embodiment one is, described Compact Mounts is horizontal baffle 8, and this horizontal baffle 8 is symmetricly set on lower wedge type block 2 left and right side, and is connected between lower wedge type block 2 and base 3.
When the horizontal movement of beam body, the horizontal force that the transmission of beam body comes by horizontal baffle 8 passes to pier below by base 3.
Embodiment three
As shown in Figure 4, the difference of the present embodiment and embodiment one is, described Compact Mounts is for comprising horizontal baffle 8 and horizontal shear part 9, horizontal shear part 9 is symmetricly set on lower wedge type block 2 front-back, and be connected between lower wedge type block 2 and base 3, horizontal shear part 9 is symmetrical arranged two horizontal baffles 8, horizontal baffle 8 is connected with horizontal shear part 9 and base 3.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
