Abstract
The utility model relates to a rope length adjuster which comprises a pull rope and is characterized in that a sleeve is also comprised; the inner wall of the sleeve is provided with internal threads, and the sleeve is cooperatively connected with adjusting bolt threads. The inner walls at the two ends of the sleeve are provided with internal threads; the two adjusting bolts are cooperatively connected with the internal threads at two ends of the sleeve; the internal threads arranged at the inner walls at the two ends of the sleeve are arranged in a reverse revolving direction. The rope length adjuster has reasonable structural design, simple adjustment for the rope length, can realize the adjustment of the maximum rope length of 30 cm, and effectively ensures the stability of the extension bearing force of the rope. The rope length adjuster is applicable to the adjustment of the ropes of various rope type pedestrian overpasses and midfield spanning bridges.
Description
Technical field
The utility model belongs to the accessory device field of drag-line bridge building, is specifically related to a kind of long adjuster of rope that is used to regulate drag-line length.
Background technology
Increase day by day along with urbanization construction and road traffic pressure, increasing city and area are selected to build on vehicle pass-through flow road, build overpass to alleviate traffic pressure, avoid the contradiction between pedestrian and the motor vehicle, improve the traffic safety degree.The overpass of various moulding has also beautified urban construction in addition, becomes a place or zonal sign.At present China builds and the overline bridge in building all adopts the pontic of steel framework or reinforced concrete structure, its construction period is longer, making and installation cost are higher, application life is very limited, this becomes the deadly defect that the city overline bridge is built, therefore a lot of places have to adopt cost higher, administer and maintain comparatively that the underground passage of difficulty replaces overpass, and underground passage can be given moving to change and bringing bigger influence and defective of city and road pipe network.Say objectively, the traffic guiding effect of People's Bank of China's overpass is stronger than underground passage, construction period is shorter relatively, cost is lower, can in the shortest time, mix the contradiction of going by transport solution node people car, by adopting the pedestrian overcrossing of new structure and material, can be good at solving the problems that present overline bridge construction exists.
Fibre reinforced composites (FRP) are to use increasingly extensive a kind of novel structural meterials in recent years in civil engineering.It has high-strength, lightweight, remarkable advantage such as corrosion-resistant, at the reinforcement and strengthening of structure, go along with sb. to guard him aspect such as anticorrosion and obtained good application.Along with the superior function of FRP material is approved by engineering circle gradually, external many engineerings begin it is applied in the newly-built bridge, or even in the Longspan Bridge.Since the seventies in last century, the FRP material just begins to attempt using in bridge engineering.Britain, the U.S. and Israel use this new material at first as the main member in building structure and the bridge construction, and what adopted mostly at that time is GFRP (glass fibre reinforced composion, i.e. glass fiber reinforced plastic).
Since the light weight of fibre reinforced composites, and pedestrian overcrossing does not need bigger load-bearing, and therefore structure and the requirement of strength to Tower Column of A Cable Stayed Bridge needn't be too high, and should meet easy construction, sound construction and lightweight advantage.Simultaneously because the load-bearing of drag-line is less demanding, and drag-line after long-term the use tensioning and loosen adjusting and must become more frequent, to adapt to the needs of pontic and Tower Column of A Cable Stayed Bridge.
The utility model content
The purpose of this utility model provides a kind of reasonable in design, can realize the long adjuster of rope of drag-line length flexible modulation, it can realize prolongation and the shortening adjusting within the specific limits of drag-line length easily, realizes the equilibrium that drag-line draws load, guarantees the stability of drag-line bridge.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The long adjuster of a kind of rope comprises drag-line, it is characterized in that the long adjuster of described rope also comprises a sleeve, and described sleeve lining is provided with internal thread, and sleeve is connected with the adjusting bolt thread.
Concretely, the two ends inwall of described sleeve is provided with internal thread, and two regulate bolt is connected with the screw-internal thread fit at sleeve two ends respectively, and the internal thread counter-rotating direction each other that described sleeve two ends inwall is provided with is provided with.
A described wherein other end of regulating bolt is fixedlyed connected the other end stay guy of drag-line connector with the drag-line connector.
Described drag-line connector comprises that end is provided with a drag-line anchor head, and a described drag-line anchor head and a drag-line fixed cover tensioning are fixed.
The middle part of described sleeve is provided with a through hole that can supply regulating arm to pass.
The long adjuster of this rope is provided with the sleeve of internal thread by one and the adjusting bolt that cooperates with internal thread of sleeve has been realized the long adjusting of rope, the adjusting bolt can be mounted in of sleeve one end, but also be installed in two of sleeve two ends respectively, by regulating sleeve and regulate the pitch length that cooperates between bolt, can realize controlling with the length of regulating the drag-line that bolt or sleeve be connected.
Drag-line can be connected and fixed with regulating bolt or sleeve by a drag-line connector, and the sleeve other end is connected with bridge main body syndeton by regulating bolt.
The beneficial effects of the utility model are that the long controller structure of this rope is reasonable in design, and the control manipulation long to rope is simple, can realize the drag-line length adjustment of maximum 30cm length, have guaranteed that effectively drag-line bears the stability of ability.The long adjuster of this rope goes for the drag-line of various drag-line pedestrian overcrossinges, midfield span bridge and regulates.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1, the long adjuster of this rope is made up of drag-line 1, drag-line connector, sleeve 5 and two adjusting bolts 4 and 6, the two ends inwall of sleeve 5 is provided with internal thread, the middle part of sleeve is provided with a through hole 7 that can supply regulating arm to pass, two regulate bolt is connected with the screw-internal thread fit at sleeve two ends respectively, and the internal thread counter-rotating direction each other that sleeve two ends inwall is provided with is provided with.The other end of regulating bolt 4 is fixedlyed connected the other end stay guy of drag-line connector with the drag-line connector.The drag-line connector comprises that end is provided with a drag-line anchor head 2, and drag-line anchor head 2 and a drag-line fixed cover 3 tensionings are fixed.
