Abstract
The utility model provides an anchorage cable spreading apparatus, relating to the architecture pre-stress construction tool technical field. The utility model comprises a hollow shell, wherein the shell is orderly provided inside with an anchor plate provided inside with a taper hole, a clamping piece of the outer surface is the conical surface, a spring arranged between the clamping piece and the anchor plate and an end cover arranged on an opening of the shell; a position on the shell, which corresponds to the taper hole of the anchor plate, is provided with a through hole; a small end of the clamping piece is arranged in the taper hole of the anchor plate, one end of a big end of the clamping piece is extended out of the through hole of the end cover. The anchorage cable spreading apparatus of the utility model is used to spread the anchorage cable and withdraw the anchorage of the anchorage cable; when the utility model is used together with the prior arm brace and front chuck type jack with top pressurizer, the operation of moving the clamping piece of the anchorage device by hand is eliminated; thereby the utility model has the advantages of safe and reliable use; moreover, compared with prior art, the construction efficiency of the utility model is increased by 5 times.
Description
Technical field
The utility model relates to building pre-stress construction technical field of tools, and especially a kind of being used for discharges the instrument that withdraws from ground tackle to anchor cable tension force.
Background technology
In the prior art, the release of anchor cable tension force is to adopt the spike of stretch-draw jack and band window to carry out.This instrument is moving back anchor when putting vang power, anchor cable passes and adopts the spike of band window to penetrate in the stretch-draw jack again, when the stretch-draw jack is pulled out the further tensioning of anchor cable, anchor clipper is pulled out together, need this moment to withstand intermediate plate with instruments such as hand-held screwdrivers, and then by stretch-draw jack playback anchor cable, because stretch-draw jack stroke is limited, at stretch-draw jack playback stroke nearly the time, with instruments such as hand-held screwdrivers intermediate plate is dialled back again and clamped the anchor cable that tension force is still arranged in the anchor slab, unclamp the clamping of stretch-draw jack.Using such method repeats aforesaid operations, discharges fully until anchor cable tension force.Only rely on above-mentioned instrument to carry out anchor cable and put and open, its labour intensity is big, withstands intermediate plate and intermediate plate dialled back with instruments such as hand-held screwdrivers to have very big danger in the anchor slab.In addition, in post-tensioned construction, when the intermediate plate that moves back is two-chip type, often arranges intermediate plate to be put back to continue in the anchor slab to put for bending and open because of drag-line; In the pre-tensioning system construction, when the intermediate plate that moves back is three-chip type, after moving back anchor taking-up intermediate plate, also intermediate plate can't be put back to anchor slab, when at this moment anchor cable discharges, the unexpected release of Suo Li can cause the damage of instrument intermediate plate and anchor cable, and economic loss is bigger, also causes personal injury accident easily.
Summary of the invention
Subject matter to be solved in the utility model provides a kind of efficiency of construction height, and the anchor cable of processing ease, safety is put prop.
In order to address the above problem, the scheme that the utility model adopts is: it has a hollow housing, be equipped with successively in this housing and be provided with an anchor slab that is provided with taper hole in it, it has the intermediate plate of taper surface, an end cap that is located at the spring between intermediate plate and the anchor slab and is contained in described shell nozzle place outward, described housing is provided with through hole over against the position of described anchor slab taper hole, the microcephaly of described intermediate plate is arranged in described anchor slab taper hole, and an end of described intermediate plate major part stretches out the outside of described end cap through hole.
The front end of above-mentioned anchor slab is provided with screw thread and connects with described housing, and described end cap links by screw thread and described housing.
One end of the major part of above-mentioned intermediate plate is meant an end of the big end of the outside conical surface of intermediate plate, and the microcephaly's of above-mentioned intermediate plate a end is meant an end of the small end of the outside conical surface of intermediate plate.
Owing to adopted such scheme the utility model compared with prior art to have following beneficial effect:
The utility model is as a kind of instrument, it in use, match with the spike of prior art band window, the preceding cassette jack of band top pressing device, rely on its inner spring and outside top pressing device the effect of the intermediate plate in the housing to be replaced desiring moving back fully the action that eases out and clamp of the intermediate plate of ground tackle, thereby not only can need not manual operations stir anchor clipper fully, use fool proofly, and action is more reliable, and efficiency of construction improves five times than prior art.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment under user mode.
The specific embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
Shown in Figure 1, the utility model is made of hollow housing 4, anchor slab 5, spring 6, two intermediate plates 7 and end cap 8.Housing 4 links by screw thread with the front end of anchor slab 5, housing 4 is provided with through hole over against the position of anchor slab 5 taper holes, in the major part of anchor slab 5 taper holes intermediate plate 7 is housed, has taper surface outside the intermediate plate 7, the major part of intermediate plate 7 taper surfaces is provided with boss, to between the rear end face of anchor slab 5 spring 6 is housed at intermediate plate 7 boss, connects with housing 4 by screw thread outside the end cap 8, one section central through hole by end cap 8 behind intermediate plate 7 boss stretches out outside the end cap 8.
The utility model in use, be connected on spike 3 back of band window and the very heavy item of preceding cassette of the band top pressing device formed by roof pressure piston 9, jack piston 10, jack intermediate plate 11 and very heavy cylinder body 12 etc. before.When anchor cable is put construction, after spike 3 withstands on the ground tackle of being made up of the anchor slab of desiring to move back 2 and its intermediate plate 1, anchor cable passes spike 3, housing 4, anchor slab 5, intermediate plate 7, in roof pressure piston 9 and the jin top intermediate plate 11, when jin top intermediate plate 11 is clamped anchor cable to the posttension position, anchor cable drives intermediate plate 1 and withdraws from backward, can take out intermediate plate 1 this moment from the window of heel brace 3, the jack piston 10 playback anchor cable that travels forward then, travel forward before stroke will finish at jack piston 10, roof pressure piston 9 promotes intermediate plate 7 forward and overcomes the active force of spring 6 and travel forward and clamp anchor cable and enter in the anchor slab 5 to replace the clamping anchorage effects of intermediate plate 1 and anchor slab 2, jack piston 10 moves forward loosening to intermediate plate 11 afterwards, last jack piston 10 moves backward, intermediate plate 11 is clamped anchor cable again, roof pressure piston 9 discharges, can carry out putting of aforementioned process once more and open, discharge fully until tension force.
