Abstract
A kind of stretch-draw jack sliding support, comprise crossbeam, slide fastener and support bar, crossbeam is provided with slide fastener, and they sup-port is passed through at crossbeam two ends.Support bar socket is arranged at outside adjusting rod, is provided with universal caster wheel bottom adjusting rod.Be provided with cucurbit below pulley, below cucurbit, be provided with stretch-draw jack.Slide fastener is provided with pulley.By adopting said structure, by the movement of pulley on crossbeam, driving whole tensioning equipment system to move, realizing stretching construction simply and easily.Meanwhile, adjusting rod ensures that stretch-draw jack can carry out stretching construction to the stretch-draw object of differing heights.And universal caster wheel is set bottom the support bar of bracing or strutting arrangement, realizing whole bracing or strutting arrangement with this can carry out displacement easily.Meet in stretching construction by the jack suspending Different Weight in midair, the different prestressing force demands of different structure.And this apparatus structure is simple, easy to operate, cost is lower.
Description
Technical field
The utility model relates to the realm of building construction, particularly a kind of stretch-draw jack sliding support.
Background technology
Along with the development of technology, the more and more application of prestressing force is in the structure, easy and simple to handle, and the jack tension bracing or strutting arrangement of use safety obtains technical staff and pays close attention to.Precast construction also more and more centralization in current engineering project, industrialization, also requires that prestressed stretch-draw operation improves work efficiency, safe and reliable.Long structure, high-prestressed structural requirement such as grade configures more greatly, heavier jack, to meet manufacturing requirements.
Summary of the invention
The purpose of this utility model is: provide the stretch-draw jack sliding support that a kind of adaptive faculty is strong, easy to operate and with low cost, it can overcome above-mentioned the deficiencies in the prior art, make and easy to use fast, cost is low, stretching process is also very safe and reliable.
The purpose of this utility model is achieved through the following technical solutions: a kind of stretch-draw jack sliding support, and comprise crossbeam, slide fastener and support bar, crossbeam is provided with slide fastener, and they sup-port is passed through at crossbeam two ends.
In preferred scheme, described support bar socket is arranged at outside adjusting rod, is provided with universal caster wheel bottom adjusting rod.
In preferred scheme, be provided with cucurbit below described pulley, below cucurbit, be provided with stretch-draw jack.
In preferred scheme, described pulley can horizontally slip on crossbeam, and stretch-draw jack can move under cucurbit traction.
In preferred scheme, described crossbeam adopts backrest channel-section steel assembled, and slide fastener adopts steel plate to make, and support bar adopts welded tube to be made into square support, and adjusting rod adopts and regulates collet to make.
In preferred scheme, described slide fastener is provided with pulley, and crossbeam is when jack weight is less, and the structure that support bar can be adopted to pass pulley substitutes.
A kind of stretch-draw jack sliding support that the utility model provides, by adopting said structure, by the movement of pulley on crossbeam, driving whole tensioning equipment system to move, realizing stretching construction simply and easily.Meanwhile, the adjusting rod of setting can adjust according to stretch-draw object height, ensures that stretch-draw jack can carry out stretching construction to the stretch-draw object of differing heights.And universal caster wheel is set bottom the support bar of bracing or strutting arrangement, realizing whole bracing or strutting arrangement with this can carry out displacement easily.Crossbeam adopts backrest channel-section steel assembled, can bear larger jack, and when jack weight is less, support bar welded tube can be utilized directly to substitute through pulley.Meet in stretching construction by the jack suspending Different Weight in midair, the different prestressing force demands of different structure.And this apparatus structure is simple, easy to operate, cost is lower.
Accompanying drawing explanation
Be described further below in conjunction with drawings and Examples.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is crossbeam of the present utility model and slide fastener link position structural representation.
Fig. 3 is support bar of the present utility model and pulley link position structural representation.
In figure: crossbeam 1, slide fastener 2, support bar 3, adjusting rod 4, universal caster wheel 5, pulley 6, cucurbit 7, stretch-draw jack 8.
Detailed description of the invention
As shown in Figures 1 to 3: a kind of stretch-draw jack sliding support, comprise crossbeam 1, slide fastener 2 and support bar 3, crossbeam 1 is provided with slide fastener 2, and crossbeam 1 two ends are supported by support bar 3.
In preferred scheme, described support bar 3 socket is arranged at outside adjusting rod 4, is provided with universal caster wheel 5 bottom adjusting rod 4.Adopt universal caster wheel to drive whole bracing or strutting arrangement, can move easily for different stretching construction position, and the support bar of socket can carry out height adjustment, increases with this scope that jack can carry out stretching construction.
In preferred scheme, be provided with cucurbit 7 below described pulley 6, below cucurbit 7, be provided with stretch-draw jack 8.
In preferred scheme, described pulley 6 can horizontally slip on crossbeam 1, and stretch-draw jack 8 can move under cucurbit 7 is drawn.Utilize cucurbit to drive stretch-draw jack to move on the vertical plane of crossbeam place, realize carrying out stretching construction to the stretch-draw object of differing heights.
In preferred scheme, described crossbeam 1 adopts backrest channel-section steel assembled, and slide fastener 2 adopts steel plate to make, and support bar 3 adopts welded tube to be made into square support, and adjusting rod 4 adopts and regulates collet to make.
Preferred scheme is as in Fig. 3, and described slide fastener 2 is provided with pulley 6, and crossbeam 1, when jack weight is less, can adopt support bar 3 to substitute through the structure of pulley 6.When jack weight is less, crossbeam assembled for backrest channel-section steel is replaced by the support bar that welded tube makes, reduces the cost of whole bracing or strutting arrangement.
Be described further below in conjunction with example:
During stretching construction, first move before whole stretch-draw support is fixed on stretching end, hung over by cucurbit on slide fastener, swing cucurbit and slide fastener is slided to crossbeam rear end, fall cucurbit and hook stretch-draw jack, traction jack rises to stretch-draw Shu Gaodu.Then stretch-draw bundle is penetrated jack, slip slide fastener passes anchor plate and intermediate plate before making jack top.Namely complete a branch of prestressed stretch-draw according to design drawing and specification stretch-draw, the above-mentioned operation that circulates completes place stretching end stretch-draw.Mobile whole support supports down to another place's stretching end at universal caster wheel, and adjusting rod can according to stretch-draw object height up and down, before whole stretch-draw support is fixed on stretching end.
Be proven, the utility model has simple and efficient to handle, use safety, stable, the advantage reduced costs.
