Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in this utility model, below in conjunction with this practicality
Accompanying drawing in new embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that
Described embodiment is only a part of embodiment of this utility model rather than whole embodiments.New based on this practicality
Embodiment in type, the every other reality that those of ordinary skill in the art are obtained under not making creative work premise
Execute example, all should belong to the scope of this utility model protection.
This utility model embodiment uses the mode gone forward one by one to write.
As shown in FIG. 1 to 3, a kind of bridge earthquake resistance attachment means, including 1, two stopping means 2 of four fixing devices
With three drag-lines 3, four fixing device 1 combination of two, by one between two fixing devices 1 in each combination
Drag-line 3 is symmetrical to be connected, and is provided with a stopping means 2 in the middle of the every drag-line 3 connecting two fixing devices 1, and two
Connected by a drag-line 3 between individual stopping means 2；Fixing device 1 includes fixing seat 11, compression spring 12 and steel
Backing plate 13, drag-line 3 two ends all sequentially pass through fixing seat 11, compression spring 12 and billet 13, by fixture 4
Fix with billet 13 and be connected；Stopping means 2 includes limited block 21 and three yielding rubbers 22, and limited block 21 is ladder
Body, is provided with two passes in prismatoid, two passes connects the opposite flank of prismatoid respectively, the axle of two passes
Line intersects vertically, and each parallel to the upper and lower surface of prismatoid；Three yielding rubbers 22 are arranged on three of prismatoid
Side periphery, it is spacing back on another towards two sides and this prismatoid of fixing device 1 that three sides are respectively prismatoid
One side of block 21；The center of yielding rubber 22 is fixed on drag-line 3 by fixture, yielding rubber 22
And there is also gap between the side of prismatoid, cross passage and penetrate between drag-line therein, yielding rubber and prismatoid
Side between the gap that exists use and in the case of frequently occurred earthquake effect, small movements and flatulence of heat type for beam body are cold normal
Contracting leaves space, it is ensured that bridge can normal operation.
Bridge earthquake resistance attachment means is applied to the junction of adjacent two beam body, and during use, three drag-lines 3 overlook into I shape,
The drag-line 3 wherein connected between two stopping means 2 is set in parallel in below the gap between two beam body, and two beam body about
This drag-line 3 is symmetrical arranged, and this zip 3 is fixed on beam pier top by two stopping means 2, and four fixing devices 1 are respectively
Being symmetricly set in adjacent two beam body both sides, the drag-line 3 of every side becomes under the restriction of stopping means 2 in two fixing devices 1
V-shaped, such coupling beam device, existing reliable longitudinal girder falling performance, there is again good horizontal girder falling effect,
Perfect in shape and function, simple for structure, it is to avoid the generation of earthquake decline beam accident, reach the purpose provided fortification against earthquakes；Structure letter simultaneously
Single, easy to operate, it is easy to promote the use of.
As shown in Fig. 4～Fig. 6, in rarely occurred earthquake, it may happen that following several situations between two adjacent beam body:
A, adjacent two beam body are moved along the same direction being parallel to Liang Dun, now connect two drag-lines of fixing device 1
3 sides being fitted in limited block 21 internal channel, limit two beam body and continue skew；
B, adjacent two beam body, along being parallel to the contrary square motion of Liang Dun, now connect two drag-lines of fixing device 1
3 rotate to an angle relative to the cross passage intersected vertically in limited block 21 after receive the restriction of passway, prevent two beams
Body continues skew；
C, adjacent two beam body are moved along the same direction being perpendicular to Liang Dun；It is now placed in two limited block 21 the same sides
Yielding rubber 22 is fitted in described limited block 21 side, limits two beam body and continues skew；
D, limited block 21 lost efficacy, it is impossible to limiting adjacent two beam body, two beam body fall simultaneously, but were falling
During connect two drag-lines 3 of two beam body and can be limited by Liang Dun, it is possible to ensure that the beam body beam that will not fall destroys.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to recognize
Fixed of the present utility model being embodied as is confined to these explanations.Ordinary skill for this utility model art
For personnel, without departing from the concept of the premise utility, its steel structure can be flexible and changeable, can be with derived line
