Description
Technical field
The utility model relates to a kind of bridge anti-fall girder apparatus, particularly a kind of guy of twisted steel cable formula anti-fall girder apparatus.
Background technology
The major disaster that earthquake causes is well-known, bridge is as the multi-purpose project in the traffic lines, in case avalanche takes place then whole transportation network is paralysed, bring great difficulty for shake back disaster relief work, secondary disaster is increased the weight of, particularly, will influence the running of entire city production and the performance of function, thereby cause tremendous loss modern city.Therefore, catastrophic damage such as the beam that falls that takes place during for fear of earthquake generally all adopt anti-fall girder apparatus when bridge design.And the pattern of China's anti-fall girder apparatus mainly contains crab-bolt formula, block type, steel bracket type etc. at present, wherein most widely used is block type, but because the block type anti-fall girder apparatus seldom is provided with necessary padded coaming between block and beam body, which floor asphaltic felt what have just puts, of long duration, asphaltic felt is aging, and its anti-fall beam effect is also just poorer; And the anti-fall beam effect of the anti-fall girder apparatus of other pattern is also unsatisfactory, and structure is also reliable inadequately.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of guy of twisted steel cable formula anti-fall girder apparatus, to solve the reliable inadequately problem of anti-fall beam weak effect, structure that prior art exists.
The technical scheme that solves the problems of the technologies described above is: a kind of guy of twisted steel cable formula anti-fall girder apparatus, comprise the ground tackle that connects drag-line, is installed in connection drag-line two ends, described connection drag-line is a steel strand integral bundle extruding drag-line, described ground tackle is the steel strand integral bundle Extrusion anchor ground tackle that comprises anchoring cartridge, nut, and this ground tackle also has snubber in the installed inside of nut; It is the mobile terminal ground tackle that the described ground tackle that is installed in connection drag-line two ends has an end at least, and this mobile terminal ground tackle also is equipped with spring between described nut and snubber, and on steel strand integral bundle extruding drag-line deflector is installed also.
Further technical scheme of the present utility model is: described snubber mainly is made up of buffer plate and the high-damping rubber pad that is built-in with steel plate.
Described spring is a volute spring, and baffle plate also is installed between this spring and nut.
Described deflector has tubaeform endoporus.
The two halves formula structure of described deflector for adopting high-strength active powder concrete or epoxy polymer to make.
Of the present utility model more further technical scheme be: described steel strand integral bundle extruding drag-line comprises many anticorrosive steel strands, high-strength polyester band and outer hdpe layer sheath in will many anticorrosive steel strands being wrapped in, and described each root anticorrosive steel strand includes PC steel strand, anticorrosion grease and PC steel strand, anticorrosion grease are wrapped in interior interior hdpe layer sheath.
Described steel strand integral bundle Extrusion anchor ground tackle comprises anchoring cartridge, nut, sealing drum and the sealing device that is arranged on sealing drum one end; Be provided with a plurality of steel strand extruded holes in the described anchoring cartridge, have the external screw thread that matches with nut inner thread on the anchoring cartridge cylindrical; Described sealing drum is installed in the end of anchoring cartridge, and is perfused with the filler that bonds that can protect steel strand within it, and the described sealing device that is arranged on sealing drum one end is installed between the finished product rope of sealing drum and steel strand integral bundle extruding drag-line.
Described ground tackle also is equipped with protective cover outward.
Because adopt said structure, the guy of twisted steel cable formula anti-fall girder apparatus of the utility model is compared with existing anti-fall girder apparatus, has following beneficial effect.
1, have reliable anti-fall beam function:
Because the utility model guy of twisted steel cable formula structure, it comprises the ground tackle that connects drag-line, is installed in connection drag-line two ends, and the ground tackle at two ends all is equipped with snubber, and wherein the mobile terminal ground tackle also is provided with baffle plate, volute spring and deflector.Described baffle plate, volute spring can make and the utlity model has certain axial internal clearance, and it can prevent that under severe earthquake action power bridge from dropping; Snubber available buffer seismic forces is to the influence of bridge construction, is installed in deflector on the steel strand integral bundle extruding drag-line and can also prevents to connect drag-line and bend disrumpent feelings under severe earthquake action.
2, have good antidetonation destruction, shock proof ability:
Because snubber of the present utility model mainly is made up of buffer plate and the high-damping rubber pad that is built-in with steel plate, wherein buffer plate can be delivered on the high-damping rubber pad connecting the stressed of drag-line, and the steel plate in this high-damping rubber pad can improve the whole rigidity of snubber, makes its effective support connect drag-line; And the high-damping rubber between each steel plate is given snubber and is absorbed energy, elastic reset and supporting capacity, and this makes snubber have good antidetonation destruction, shock proof ability.
3, can relax local buckling stress and have guide effect:
Because the utility model also includes deflector, this deflector has guide effect for the multi-directional bending that earthquake causes, and can relax the local buckling stress that occurs in the connection drag-line, makes ground tackle can not produce flexure stress and shear stress.In addition, because this deflector adopts high-strength active powder concrete or epoxy polymer to make, its compressive strength is higher, can afford bigger deflection compressive stress.
In addition, because connection drag-line of the present utility model adopts steel strand integral bundle extruding drag-line, it also has the following advantages:
(1), each stress unit isolates mutually, under corrosive environment, very difficult meeting runs into the situation of corrosion degree basically identical, therefore, drag-line from the part or part muscle material disrumpent feelings to whole fracture, have one long period and significantly distortion, the maintenance personnel find easily and can in time get rid of hidden danger.
(2), the cable body diameter is less;
Have, because ground tackle of the present utility model adopts the steel strand integral bundle Extrusion anchor ground tackle, it also has the following advantages again:
(1), be connected between anchoring cartridge and the steel strand reliable, safe.The steel strand boundling penetrates anchoring cartridge, can adjust the thrust of extrusion machinery and the length that compresses according to stressed needs, makes anchoring cartridge be squeezed the back plastic strain and the bond stress to steel strand that produces can guarantee can not take place the stripped thread situation; Simultaneously, because the hardness ratio steel strand of anchoring cartridge is low, steel strand are damaged can be not big as the intermediate plate anchor, can reach the better anchoring efficiency factor.In addition, no matter how stressed steel strand are, anchoring cartridge all is constant to its bond stress, and at the steel strand low stress, or even negative stress can not get loose.
(2), the outside dimension of anchoring cartridge is more much smaller than hawser ground tackles such as chill casting anchor, hot-cast anchor, and is littler with the clip type steel strand anchorage, and structure preformed hole size is reduced, and helps the structure optimization of bridge.
(3), bond filler between steel strand in the anchoring cartridge, make it in ground tackle, all can be in mutual isolation from a free section cable body.
Below, the technical characterictic to the guy of twisted steel cable formula anti-fall girder apparatus of the utility model is further described in conjunction with the accompanying drawings and embodiments.
