Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings;
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
Refering to shown in Fig. 1, a kind of novel building prestressing apparatus, including oil cylinder 1, piston 2, instrument anchor slab 3, tool clamping piece
4, limiting plate 5, steel strand wires 6, anchor plate 7 and high-pressure oil pump 20, described oil cylinder 1 is internally provided with piston 2, before described oil cylinder 1
Being provided with work anchor slab 9 on end, described work anchor slab 9 is provided with work clip sheet 8, described work anchor slab 9 is by work clip sheet 8
It is arranged with steel strand wires 6, described work anchor slab 9 side is correspondingly arranged on limiting plate 5, on the supporting seam of described piston 2 end
It is provided with instrument anchor slab 3, described instrument anchor slab 3 is provided with tool clamping piece 4, below described oil cylinder 1, is provided with pipeline A and pipeline
B, described oil cylinder 1 is connected with high-pressure oil pump 20, described pipeline A and pipeline B and high pressure by pipeline A and pipeline B through pipeline
Stop valve 10, choke valve 11 and relief valve 12 it is disposed with between oil pump 20.
It should be noted that and be additionally provided with overflow valve 15 between described pipeline B and high-pressure oil pump 20.
It should be noted that and on described pipeline A and pipeline B and the pipeline of high-pressure oil pump 20, be provided with Pressure gauge 13 and unidirectional
Valve 14.
It should be noted that the outer side-lower of described instrument anchor slab 3 is provided with anchor plate 7.
B road stop valve (oil return valve) is opened by this utility model, and A road stop valve is closed, and starts oil pump, to tension cylinder fuel feeding
Carry out stretch-draw.Regulate choke valve, to control oil pressure height and tensioning speed simultaneously;Intermediate plate when piston is overhanging, in moveable anchor
Steel strand wires can be clamped voluntarily.Intermediate plate in work anchor is now limited by limiting plate, is carried over into locating dimension only the most voluntarily
Stop;When stretch-draw reaches process specifications, choke valve should be circled round, i.e. stop, to A road fuel feeding, the gentliest returning stop valve
(oil return valve), A road pressure is down to zero point.Due to the retraction of steel strand wires, piston will be pulled some millimeters, the at this moment folder of work anchor
Clamp voluntarily in sheet is brought into anchor slab;Stop valve is closed on B road, and throttle valve control is boosted, and backward stroke of the piston stays 10 20 millimeters slightly
Returning choke valve, when making piston put in place, pressure is not more than 25MPa, then opens stop valve, and B road pressure drops to zero point, closes power supply
Shut down.
The standardized element that this utility model uses all can commercially, shaped piece according to description and accompanying drawing
Record all can carry out customized, the concrete connected mode of each part all uses in prior art ripe bolt, rivet, weldering
