Abstract
A prestress tensioning limit plate is characterized by comprising a limit plate body and a reference circle plate which are mutually hinged. A limit plate steel strand hole for installation of a steel strand is formed in the limit plate body, and a reference circle plate steel strand hole for installation of the steel strand is formed in the reference circle plate. The limit plate body and the reference circle plate are mutually hinged, so a hole is formed in the middle of the limit plate. A rotating shaft on the reference circle plate is hinged to the hole in the middle of the limit plate. The prestress tensioning limit plate has the advantages that the problem that a work anchor plate has to correspond to the hole of the limit plate when a worker wears the steel strand is avoided, labor efficiency of workers is improved, and the probability of wrong wearing of the steel strand is reduced.
Description
Technical field
The utility model relates to a kind of pre-stress stretching device for the civil building steel strand, particularly relates to a kind of prestressed stretch-draw limiting plate.
Background technology
Existing prestressed stretch-draw is the integral structure design with limiting plate, as shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 5.This limiting plate must make the position, hole of limiting plate arrange to arrange corresponding one by one with the position, hole of the anchor slab of working when mounted, this limiting plate is close to the work anchor slab in stretching process, if misdrawed, steel strand will limited plate and the work anchor plate holder dead, carry out stretch-draw in the situation that folder is dead, just probably broken in the situation that do not reach stretch-draw requirement steel strand.Existing limiting plate has the following disadvantages: (1) is not easy to install, and installation process is consuming time many; (2) in the situation that wrongly installed is easily broken steel strand.
The utility model content
The purpose of this utility model just is to provide the problem that a kind of workman of solution must be corresponding in steel strand time work anchor slab and spacing plate hole position, raising workman's efficiency, and the prestressed stretch-draw limiting plate of the probability of steel strand is misdrawed in minimizing.
Solution of the present utility model is such: the utility model comprises limiting plate and calibration plectane, described limiting plate and calibration plectane are hinged, have the limiting plate steel strand hole that steel strand are installed on described limiting plate, have the reference circle slab twisted wire hole that steel strand are installed on described calibration plectane.
Further: described limiting plate and calibration plectane are hinged and are the middle part perforate of limiting plate, and the hole in the middle part of the rotating shaft on the calibration plectane and limiting plate is hinged.
Further: the thickness of described calibration plectane is identical with the thickness at the place, limiting plate steel strand hole of limiting plate
Further: described limiting plate and the calibration plectane place of being hinged are provided with the limited step that restriction calibration plectane moves right.
The utility model has the advantages that and avoid the workman to work problem that anchor slab and spacing plate hole position must be corresponding improve workman's efficiency when steel strand, the probability of steel strand is misdrawed in minimizing.
Description of drawings
Accompanying drawing is used for explaining the utility model.
Accompanying drawing 1 is the structural representation that traditional prestressed stretch-draw is used limiting plate.
Accompanying drawing 2 is sectional views of accompanying drawing 1.
Accompanying drawing 3 is structural representations of the present utility model.
Accompanying drawing 4 is sectional views of accompanying drawing 3.
Accompanying drawing 5 is working condition schematic diagrames of traditional limiting plate.
Accompanying drawing 6 is working condition schematic diagrames of the present utility model.
The specific embodiment
The utility model comprises limiting plate 1 and calibration plectane 2 as shown in accompanying drawing 3 and accompanying drawing 4, and described limiting plate 1 is hinged with calibration plectane 2, can mutually rotate.Have the limiting plate steel strand hole that steel strand are installed on described limiting plate, have the reference circle slab twisted wire hole that steel strand are installed on described calibration plectane 2.Described limiting plate 1 is hinged with calibration plectane 2 and is the middle part perforate of limiting plate 1, and the hole in the middle part of the rotating shaft on calibration plectane 2 and limiting plate is hinged.The thickness of described calibration plectane 2 is identical with the thickness at the place, limiting plate steel strand hole of limiting plate 1.
As shown in Figure 4, described limiting plate 1 is provided with calibration plectane 2 places of being hinged and limits the limited step that calibration plectane 2 moves right.
Hole on the large reference circle of the present embodiment is equally distributed; Three holes on little reference circle are also equally distributed and can rotate.
Because the hole is equally distributed, on perforation steel strand and little reference circle, the perforation steel strand misplace if put on the large reference circle of the rear discovery of steel strand 3, and it is that recoverable limiting plate 1 realizes that with the anchor slab 4 of working the position, hole is corresponding one by one that rotation divides the body opening position, as shown in Figure 6.Thereby reduced the probability of misdrawing steel strand, improved operating efficiency.
