Embodiment
In order to make those skilled in the art more fully understand the technical solution in the present invention, below in conjunction with of the invention real
The attached drawing in example is applied, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described implementation
Example is only part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this area is common
Technical staff's all other embodiments obtained without making creative work, should all belong to protection of the present invention
Scope.
The embodiment of the present invention is write by the way of progressive.
As shown in FIG. 1 to 3, a kind of anti-fall girder apparatus, including four fixing devices, 1, two limiting device 2 and three drawings
Rope 3, four 1 combination of two of fixing device, are symmetrically connected in each combination between two fixing devices 1 by a drag-line 3,
And a limiting device 2 is provided among the drag-line 3 of two fixing devices 1 of every connection, pass through one between two limiting devices 2
Root drag-line 3 connects；Fixing device 1 includes fixed seat 11, compression spring 12 and billet 13, and 3 both ends of drag-line sequentially pass through solid
Reservation 11, compression spring 12 and billet 13, are fixedly connected by fixing piece 4 with billet 13；Limiting device 2 includes limited block
21 and three yielding rubbers 22, limited block 21 be prismatoid, be provided with two passes in prismatoid, two passes connect ladder respectively
The opposite flank of body, the axis of two passes intersect vertically, and each parallel to the upper and lower surface of prismatoid；Three buffering rubbers
Glue 22 is arranged on three side peripheries of prismatoid, and three sides are respectively prismatoid towards the two sides of fixing device 1 and are somebody's turn to do
Prismatoid is back on a side of another limited block 21；The center of yielding rubber 22 is fixed on drag-line 3 by fixing piece
On, there is also gap between the side of yielding rubber 22 and prismatoid, cross passage and penetrate between drag-line therein, buffering rubber
Existing gap is the small movements of beam body in the case where normal use and frequently occurred earthquake act between the side of glue and prismatoid
Space is left with expanding with heat and contract with cold, ensures that bridge being capable of normal operation.
Anti-fall girder apparatus is applied to the junction of adjacent two beam body, and three drag-lines 3 are overlooked into I-shaped during use, wherein connecting
Connect below the gap that the drag-line 3 between two limiting devices 2 is arranged in parallel between two beam bodies, and two beam bodies are right on the drag-line 3
Claim to set, which is fixed on beam pier top by two limiting devices 2, and four fixing devices 1 are symmetrically arranged in adjacent two
Beam body both sides, the drag-line 3 per side under the limitation of two fixing devices 1 and limiting device 2 into V-shaped, such coupling beam device,
Existing reliable longitudinal girder falling performance, but with good horizontal girder falling effect, perfect in shape and function is simple for structure, avoids ground
Earthquake centre falls the generation of beam accident, achievees the purpose that to provide fortification against earthquakes；Simple in structure, easy to operate, use easy to spread at the same time.
As shown in Fig. 4~Fig. 6, in rarely occurred earthquake, following several situations may occur between two adjacent beam bodies：
A, adjacent two beam body is moved along the same direction parallel to Liang Dun, and two drag-lines 3 for connecting fixing device 1 at this time paste
Close and continue to deviate in the side of 21 internal channel of limited block, two beam bodies of limitation；
B, two piece drag-line 3 phases of adjacent two beam body along the opposite square motion parallel to Liang Dun, at this time connection fixing device 1
The limitation of passway is received after rotating by a certain angle for the cross aisle to intersect vertically in limited block 21, prevents two beam bodies from continuing
Offset；
C, adjacent two beam body is moved along the same direction perpendicular to Liang Dun；It is now placed in the buffering of two limited blocks, 21 the same side
Rubber 22 is fitted in 21 side of limited block, and two beam bodies of limitation continue to deviate；
D, limited block 21 fails, and adjacent two beam body can not be limited, and two beam bodies fall at the same time, but in the process of whereabouts
Two drag-lines 3 of two beam bodies of middle connection can be limited be subject to Liang Dun, can ensure that beam body will not fall beam destruction.
Above content is that a further detailed description of the present invention in conjunction with specific preferred embodiments, it is impossible to is assert
