Description

The tie bar cable system of band wire separating ring

Technical field:

The utility model relates to and is applied to concrete or steel work, as the tie bar cable system in the steel tube arch structural bridge.

Background technology:

Arch bridge has long applicating history in bridge engineering, be to adopt a kind of very widely structural shape in the bridge.And the tie-rod rope is the key structure unit that is bearing by dead load and the caused horizontal thrust of mobile load in arch bridge, is the life place of bridge engineering.Along with modern bridge to stride greatly the footpath continuous development, the specification that is applied to the tie-rod rope in the arch bridge is also increasing.According to prior art, the steel strand tie-rod rope that is adopted is to cohere steel strand and the tie-rod cable anchorage is made by steel strand finished product rope or many nothings, and cable body wherein partly is to make by wearing the high strength low relaxed prestress steel strand bundle in the HDPE outer tube.The weight of cable body itself is that the Support bracket by per 3～5 meters intervals supports.

This form of structure has following defective and inconvenience in the construction of tie-rod rope and working service process:

1,, when passing the HDPE outer tube, steel strand can not guarantee between each root steel strand and be arranged in parallel that phase mutual interference friction also just can't realize single tendon stretch between each steel strand, can make troubles the increase construction cost to construction independent for the tie-rod rope.

2, for the bigger tie-rod rope of specification, even stretch-draw is to the proof stress of tie-rod rope, because the weight of self, will certainly cause the interior steel strand mutual extrusion of pipeline, overlapping, in this case, not only can't carry out single tendon stretch, also can't carry out the replacing of single steel strand in the future, bring very inconvenience for the maintenance of bridge in construction and the use.

3, because the contact surface of the HDPE outer tube of passive Support bracket and tie-rod rope is less; can cause the distortion of the Support Position HDPE of place outer tube generation lateral expansion; influence the attractive in appearance of construction and cable body; even cause damage; make tie-rod rope part lose the protection of outer tube, have influence on the application life of tie-rod rope.

The utility model content:

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of tie bar cable system with wire separating ring is provided, separate to guarantee each root steel strand, be convenient to installation, stretch-draw, monitoring and the replacing of single steel strand, avoid the HDPE outer tube lateral expansion distortion to take place at place, Support bracket Support Position.

The utility model is that the technical scheme that the technical solution problem is adopted is:

The tie bar cable system of the utility model band wire separating ring, its design feature is in the outer tube of tie-rod rope, be positioned at place, Support bracket position wire separating ring is set, wire separating ring is a disc-shaped component, the steel strand through hole that is used for steel strand that wire separating ring has is separate, that equate with the quantity of steel strand, axis all parallels with the axis of outer tube, every steel strand independently are located in the steel strand through hole of wire separating ring corresponding position, form parallel and separate between each root steel strand.

The design feature of the tie bar cable system of the utility model band wire separating ring also is the periphery of wire separating ring, and a positioning rope hole and two guide rail rope holes are set respectively on the position triangular in shape.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model utilizes wire separating ring to make in the tie-rod rope each root steel strand keep independence and be arranged in parallel, can realize single tendon stretch, controls the uniformity of each root steel strand Suo Li of every Shu Suozhong better, also is convenient to construction, saves construction cost.

2, the wire separating ring that is provided with at interval in the utility model makes that each root steel strand is spaced from each other in the tie-rod rope, not overlapped, mutual extrusion not makes bridge very convenient in the future working service, promptly can carry out monitoring and the replacing of Suo Li to any steel strand under the situation that does not influence traffic.

3, each wire separating ring is arranged on the Support bracket in the utility model, improved the rigidity of the tie-rod rope Support Position HDPE of place outer tube, effectively avoided the lateral expansion distortion of HDPE outer tube, the convenient construction of tie-rod rope, safeguard the attractive in appearance of tie-rod rope, guaranteed the ordinary life of outer tube.

4, the utility model can make construction equipment lighting, miniaturization, is convenient to construction, monitoring, safeguards, has saved human and material resources and engineering time, reduces construction and use cost.
