Abstract
The utility model relates to a structure in the technical field of bridge manufacture, in particular to a shaping clamp of linear unit main cable strand of a simulated suspension bridge. The shaping clamp comprises a toothed clamp body, a toothed clamp cover, bolts, nuts, and fixed bolts, wherein the toothed clamp body is matched with the toothed clamp cover and fixed through the bolts, the nuts and the fixed bolts. The shaping clamp is characterized in that the toothed shapes on the toothed clamp body and the toothed clamp cover are consistent with the shape of the gap of the rectangular cable strand so as to keep the wire in the gap position immobile. Therefore, scattering or wire displacement of the cable strand before lapping is prevented, and the always consistent cross-section shape of the cable strand is guaranteed.
Description
Technical field
The utility model relates to the structure in a kind of bridge manufacturing technology field, specifically is a kind of reshaping clamp of unit strand imitating main cable linearity of suspension bridge.
Background technology
Unit strand is the composition of main push-towing rope in bridges such as suspension bridge, self-anchored suspension bridge and the building structure, is the stressed member of the bearing load of main push-towing rope in bridges such as suspension bridge, self-anchored suspension bridge and the building structure.The steel wire length that present unit strand is formed a bundle strand is all identical, on the bundle thigh of a segment distance at a certain distance at steel tendon thigh outer wrapping reinforced polyester band or finer wire.Along with the development of bridge technology, in bridges such as some suspension bridges, self-anchored suspension bridge and building structure, require main push-towing rope can carry out bending.Yet traditional unit strand owing to the complexity of main cable linear, makes that every steel wire is stressed and unbalanced, thereby makes indivedual steel wires stressed greater than other steel wire that the tensile strength that may surpass steel wire that has cause the existence of potential safety hazard behind imposed load.This just requires to form the relative length difference of every steel wire in the steel tendon thigh of main push-towing rope, to guarantee unit strand (or claiming strand) every steel wire stress equalization behind imposed load.
Because the particularity of its shape, traditional hexagon main push-towing rope bundle thigh is inapplicable, has made the whole rectangular unit strand of its cross section into.But the strand of square-section is from its cross section, and the compact degree of its structure causes it in process not as the cellular structure of traditional hexagon main push-towing rope unit strand, the bundle burst phenomenon that appearance is at random or steel wire misplaces before wrapped.
Summary of the invention
The utility model provides a kind of reshaping clamp of unit strand imitating main cable linearity of suspension bridge at above-mentioned the deficiencies in the prior art, prevents to restraint thigh and a phenomenon at random or the steel wire dislocation occurs before wrapped, guarantees that the cross sectional shape of bundle thigh remains unanimity.
The utility model is achieved by the following technical solution, and the utility model comprises: zigzag clamp, serrated clips lid, bolt, nut, set bolt.The zigzag clamp matches with the serrated clips lid, and fixes by bolt, nut, set bolt three.It is characterized in that, described zigzag clamp, serrated clips lid, the seam shape of zigzag fashion on it and RECTANGULAR BEAM thigh coincide, and makes the fixation with steel wire of its gap position motionless.
Compared with prior art, zigzag fashion of the present utility model has just in time been filled up the space that is presented in the bundle burst cross section, and can make the fixation with steel wire of its position, space motionless, is unlikely to make the steel wire dislocation, to obtain a good section of steel wire shape.And the utility model can also continue to step up certain amount clip to the position on bundle strand after, and is compacter between the steel wire of bundle strand and the steel wire when making twining package tape or finer wire wrapped, prevents that wrapped power is not enough and causes the steel wire after wrapped at random.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of symbols: 1-zigzag clamp, 2-serrated clips lid, 3-bolt, 4-nut, 5-set bolt.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment has provided detailed embodiment being to implement under the prerequisite with technical solutions of the utility model, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: zigzag clamp 1, serrated clips lid 2, bolt 3, nut 4, set bolt 5.Zigzag clamp 1 matches with serrated clips lid 2, and fixes by bolt 3, nut 4, set bolt 5 threes.It is characterized in that, described zigzag clamp 1, serrated clips lid 2, the seam shape of zigzag fashion on it and RECTANGULAR BEAM thigh coincide, and makes the fixation with steel wire of its gap position motionless.Zigzag fashion has just in time been filled up the space that is presented in the bundle burst cross section, and can make the fixation with steel wire of its position, space motionless, is unlikely to make the steel wire dislocation, to obtain a good section of steel wire shape.And the utility model can also continue to step up certain amount clip to the position on bundle strand after, and is compacter between the steel wire of bundle strand and the steel wire when making twining package tape or finer wire wrapped, prevents that wrapped power is not enough and causes the steel wire after wrapped at random.
