The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Prestress wire actinobacillus device, comprises framework 1 and cylindrical-conical unwrapping wire casing 2, and described unwrapping wire casing 2 is fixedly installed on framework 1 front.
The cube structure of described framework 1 for being welded by channel-section steel.Described framework 1 bottom is provided with crossbeam 7, as the lower support structure of whole dish prestress wire.As preferably, described crossbeam 7 has twice, and space certain distance, in order to reasonable distribution load-bearing.Described framework 1 both sides are provided with guard rail 8, in order to prevent when the steel strand landing from the side when the construction later stage tails off of whole dish steel strand.As preferably, described guard rail 8 You San roads, are equidistantly distributed on framework 1 middle part, side.The aft end face of described framework 1 is provided with netted guard rail 9.As preferably, on described framework 1 former and later two end faces, be provided with line pressing rod 3, on described line pressing rod 3, be provided with wire pressing block.When the construction later stage remains a small amount of prestress wire, compress wire pressing block, due to the effect of steel strand self rigidity, steel strand outer contour shape and steel strand ordering can not change, and have avoided steel strand winding.
Bracing or strutting arrangement when described unwrapping wire casing 2 extracts for steel strand unwrapping wire, comprises 4 road annulus 2a of the coaxial spaced set that radius successively decreases from the inside to surface and is connected and fixed 6 straight-bar 2b of annulus 2a.Described 6 straight-bar 2b distribution that is centrosymmetric around annulus 2a axle center.Described 6 straight-bar 2b inner side is weldingly fixed on framework 1, thus the position of positioning framework 1 and unwrapping wire casing 2.
During use, whole bundle prestress wire is put into framework 1, then steel strand are extracted out from the outlet of cylindrical-conical unwrapping wire casing 2, thereby carry out prestress wire lashing work, avoided relaxing because of steel strand the steel strand that cause and flicked.
As preferably, the annulus 2a in described outside is provided with preventing rubber circle 4, in order to prevent the wearing and tearing of prestress wire.
As preferably, described framework 1 top is provided with mobile suspension ring 5, handling and movement to whole dish steel strand while having facilitated construction.
Because of the operation in the open of steel strand line laying work, when raining season construction, steel strand, through drenching with rain and soaking, cause the corrosion of steel strand, make the quality of steel strand cannot meet the code requirement of design and construction.Therefore framework 1 is provided with 4 feets, make steel strand and ground have certain height high up in the air, prevent from getting rusty.Described framework 1 top is also provided with protection canopy cover 6, in order to prevent that steel strand from being drenched with rain.Protection canopy cover 6 can, by wiring colligation on mobile suspension ring 5, facilitate installation and the dismounting of protection canopy cover 6.The position of the corresponding mobile suspension ring 5 of protection canopy cover 6 is provided with hole, installs after protection canopy cover 6, and mobile suspension ring 5 are still exposed to top, are convenient to handling and the movement of whole dish steel strand.
The utility model is illustrated according to embodiment, is not departing under the prerequisite of present principles, and this strutting system can also be made some distortion and improvement.It should be pointed out that all employings are equal to the technical scheme that the modes such as replacement or equivalent transformation obtain, and all drop in protection domain of the present utility model.
