Description
Technical field
The invention belongs to the bridge technology field, particularly relate to the horizontal elastic damping device of a kind of bridge.
Background technology
At present, the super-huge bridge of floating or half floating system, bridge span is often very big, very big horizontal movement can take place in the beam body under mobile load effects such as vehicle, wind carry, and existing bridge generally is the vertical force that adopts vertical support carrier bar body, the vertical force bearing can't play return action when the beam body bears bigger horizontal movement under temperature, mobile load effect when, therefore, the horizontal movement that how to utilize the big horizontal rigidity control bridge mobile load of bridge attachment device to cause becomes the direction that these those skilled in the art make great efforts.
Summary of the invention
Purpose of the present invention just provides the horizontal elastic damping device of a kind of bridge, the beam body horizontal rigidity of control beam body mobile load displacement can be converted to vertical rigidity, thereby solve the problem of the horizontal insufficient rigidity of bridge.
Purpose of the present invention realizes by following technical proposals:
The horizontal elastic damping device of a kind of bridge, comprise wedge type block, following wedge type block, vertical spring, horizontal stopping means and base, be slidingly matched by trapezoidal faces or the trapezoidal faces of falling between last wedge type block and the following wedge type block, vertical spring and horizontal stopping means are connected between following wedge type block and the base.
As preferably, have many to the wedge type block group, the wedge type block group goes up wedge type block by one and constitutes with a following wedge type block, and wedge type block and all following wedge type blocks connect as a wholely separately all on, and many slide planes to the wedge type block group are trapezoidal faces, the trapezoidal faces of falling is arranged alternately.
This structure is conducive to this damping unit balance and bears horizontal load, when the beam body is applied a horizontal load, because each slide plane to the wedge type block group is trapezoidal faces, the trapezoidal faces of falling is arranged alternately, therefore this damping unit can bear the vertical force of symmetry, thereby the assurance force balance avoids taking place unbalance loading.
As preferably, described vertical spring be in rubber spring, metal spring or the rubber-metal cluster spring any one.
As preferably, described vertical spring vertically alternately is socketed to form by outer toroid and interior annulus, and the fitting face between outer toroid and the interior annulus is taper seat.
When vertical spring bears axial load, interior annulus by compression and reduced, outer toroid is stretched and enlarged-diameter, thereby interior annulus plays spring action with outer toroid along the relative generation axial deformation of sliding of taper seat, is particularly suitable for the situation that rigidity is big, structure is little.
As preferably, described horizontal stopping means comprises vertical guiding steel pipe and horizontal shear pin, and the steel pipe that vertically leads is fixed on the base, and horizontal shear pin one end is fixed on down the wedge type block bottom, and the other end inserts in the vertical guiding steel pipe.
As preferably, described horizontal stopping means is horizontal baffle, and this horizontal baffle is fixed on the base, and symmetry is connected in down face or front-back about wedge type block.
Compared with prior art, beneficial effect of the present invention is: simple in structure, reasonable in design, the horizontal force that the beam body can be subjected to is converted to vertical force, thereby realize that the big displacement movement of beam body level is converted to vertical little displacement movement, beam body horizontal damping rigidity is converted into vertical damping rigidity, avoids the horizontal movement of beam body excessive.

The specific embodiment
The present invention is further illustrated below in conjunction with specific embodiments and the drawings.
Embodiment one
As depicted in figs. 1 and 2, the horizontal elastic damping device of a kind of bridge, comprise wedge type block 1, following wedge type block 2, vertical spring, horizontal stopping means and base, go up wedge type block 1 and a pair of wedge type block group of following wedge type block 2 formations for one, be slidingly matched by trapezoidal faces or the trapezoidal faces of falling between last wedge type block 1 and the following wedge type block 2, many the wedge type block group is arranged side by side, and the face of being slidingly matched is trapezoidal faces, the trapezoidal faces of falling is arranged alternately, and wedge type block 1 and following wedge type block 2 are connected to an integral body separately by bolt on all.Described vertical spring is connected in down between wedge type block 2 and the base 3, and this vertical spring overlappingly alternately is socketed to form by outer toroid 4 and interior annulus 5 are vertical, and the fitting face between outer toroid 4 and the interior annulus 5 is taper seat.Described horizontal stopping means comprises vertical guiding steel pipe 6 and horizontal shear pin 7, and the steel pipe 6 that vertically leads places vertical spring and is fixed on the base 3, and horizontal shear pin 7 one ends are fixed on down wedge type block 2 bottoms, and the other end inserts in the 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.
This damping unit can be converted to vertical force with horizontal force, utilizes the deadweight of beam body to form horizontal rigidity.When the bridge beam body horizontal movement, the horizontal force that the beam body is subjected to passes to down wedge type block 2 by last wedge type block 1, at present wedge type block 2 horizontal directions are fixed by horizontal stopping means together, the beam body drive to go up wedge 1 along with following wedge type block 2 be slidingly matched towards on move, under the effect of beam body weight power, the vertical spring of following wedge type block 2 compressions, vertical spring produces vertical counter-force, form horizontal damping to the beam body by the trapezoidal fitting face between the upper and lower wedge type block 1,2, thereby beam body horizontal rigidity is converted to vertical rigidity.Horizontal shear pin 7 effectively passes to following pier with horizontal force.
This damping unit can use jointly with common vertical support, and when the anhydrous prosposition of beam body moved, damping unit did not produce vertical counter-force, did not namely have horizontal resistance, and 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 this moment, beam body vertical load was born jointly by vertical support and damping unit.Because this damping unit produces vertical counter-force, then produces horizontal resistance simultaneously, its horizontal resistance size increases with the increase of displacement, but the maximum vertical counter-force is no more than vertical support.
Embodiment two
As shown in Figure 3, the difference of present embodiment and embodiment one is that described horizontal stopping means is horizontal baffle 8, and this horizontal baffle 8 is symmetricly set on down wedge type block 2 left and right sides, and is connected in down between wedge type block 2 and the base 3.
When the horizontal movement of beam body, horizontal baffle 8 passes to following pier with the horizontal force that the transmission of beam body comes by base 3.
Embodiment three
As shown in Figure 4, the difference of present embodiment and embodiment one is, described horizontal stopping means is for comprising horizontal baffle 8 and horizontal shear part 9, horizontal shear part 9 is symmetricly set on down wedge type block 2 front-backs, and be connected in down between wedge type block 2 and the base 3, be symmetrical arranged two horizontal baffles 8 on the horizontal shear part 9, horizontal baffle 8 is connected with horizontal shear part 9 and base 3.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
