Abstract
The utility model relates to a pretensioning method connector, which comprises a clamping sheet 2 and a connecting anchor plate 6, wherein, the connecting anchor plate 6 is connected with a finish rolling deformed bar 4 provided with outer screw threads and a tensioning screw nut 9 by a screw thread screwing mode; the connecting anchor plate 6 is provided with an anchor eye provided with inner screw threads; the clamping sheet 2 and an automatical feeding spring 5 are arranged into the anchor eye of the anchor plate 6; a compression screw 1 is rotated on the screw threads in the anchor eye; the compression screw is screwed and pressed so that the automatical feeding spring tightly press the clamping sheet, and a steel strand 3 arranged in the clamping sheet 2 is tightly clamped. The connector has the advantages that the space between an anchoring device and a component is not required to be provided with a counterforce table seat, the operation process is very simple, convenient, and safe, the length of the demanded steel strand is shorter, and the connector can be repeatedly used for many times.
Description
The utility model relates to a kind of tensioner that the pretensioned prestressing member is carried out stretch-draw.
At present, it is with utilizing ground tackle and tensioner that the steel strand in the pretensioned prestressing member are carried out stretch-draw, in use, needing to be provided with a counter-force pedestal so that tensioner to be installed between ground tackle and member that the pretensioned prestressing member is carried out stretch-draw, make the section of stretching out steel strand increase cost height (referring to Fig. 2); 2, ground tackle is made up of anchor slab and intermediate plate, and the end face of intermediate plate might be not concordant during use, and intermediate plate follow-up state is bad when stressed, causes the steel strand stripped thread easily, intermediate plate accident such as fly out, poor reliability; When 3, the concrete of pretensioned prestressing member did not reach designing requirement, tensioner must keep stretching force, and is in running order always, and the stress instability.
The purpose of this utility model is to provide a kind of operating process very easy, safe and reliable; Required steel strand length is shorter; Can repeat nonexpondable pre-tensioning system coupling.
For reaching above-mentioned purpose, pre-tensioning system coupling of the present utility model by housing screw, intermediate plate, prestress wire, finish rolling deformed bar, automatically follow up spring, connect anchor slab, tensioning nut is formed, finish rolling deformed bar with connect anchor slab and tensioning nut and adopt the screw thread mode of screwing to connect, connect on the anchor slab tapped anchor hole is arranged, the intermediate plate and the spring that follows up are automatically put into the anchor hole that connects anchor slab, housing screw is spun on the interior screw thread of anchor hole, the spinning housing screw makes automatic follow-up spring compression intermediate plate, will be positioned at the central steel strand of intermediate plate and clamp.
Because adopt said structure, the pre-tensioning system coupling of the utility model has following advantage:
(1) the counter-force pedestal need not be set between ground tackle and member, thereby steel strand length simple in structure, safe and reliable, required is shorter.
(2) increased automatic follow-up spring and housing screw, can make the intermediate plate end face concordant, follow-up prevents that effectively intermediate plate from flying out freely, has improved reliability.
(3) by finish rolling deformed bar to the steel strand stress application after, withhold on bearing with tensioning nut, can take off tensioner.
Below, the architectural feature to pre-tensioning system coupling of the present utility model is described further in conjunction with the accompanying drawings and embodiments.
Fig. 1: the structural representation of the utility model pre-tensioning system coupling
Fig. 2: existing pre-tensioning system stretch-draw schematic diagram
Among the figure: 7-member, 8-stretching bed seat, 10-top board, 11-tensioner
Embodiment
A kind of pre-tensioning system coupling, as shown in the figure, this coupling comprises intermediate plate 2, connects anchor slab 6, on connection anchor slab 6, be connected with one and be with externally threaded finish rolling deformed bar 4 and tensioning nut 9 by the screw thread mode of screwing, on the connection anchor slab 6 tapped anchor hole is arranged, the intermediate plate 2 and the spring 5 that follows up are automatically put into the anchor hole that connects anchor slab 6, and housing screw 1 is spun on the interior screw thread of anchor hole, spinning housing screw 1 makes automatic follow-up spring 5 compress intermediate plate 2, will be positioned at intermediate plate 2 central steel strand 3 and clamp.
Claims (1)
1, a kind of pre-tensioning system coupling, comprise intermediate plate (2), connect anchor slab (6), it is characterized in that: upward being connected with one by the screw thread mode of screwing is with externally threaded finish rolling deformed bar (4) and tensioning nut (9) connecting anchor slab (6), connect on the anchor slab (6) tapped anchor hole is arranged, the intermediate plate (2) and the spring (5) that follows up are automatically put into the anchor hole that connects anchor slab (6), housing screw (1) is spun on the interior screw thread of anchor hole, spinning housing screw (1) makes automatic follow-up spring (5) compress intermediate plate (2), will be positioned at the central steel strand (3) of intermediate plate (2) and clamp.
