Background technology
FRP(fibre reinforced composites) Transverse Shear Strength of twisted wire is lower, unsuitable crooked, the drag-line that at present FRP material is made and application thereof are the study hotspots of current bridge engineering Jie He academia, but the guy cable length of large bridge easily hundreds of rice is even gone up km, FRP twisted wire must block because of transportation problem, FRP twisted wire connector is spreading twisted wire arbitrarily, is convenient to application.
If member length exceeds certain scope, temperature deformations etc. are by uncontrollable, and long member must affect prestressed stretch-draw, FRP twisted wire connector not only can bear the load with mother metal ultimate tension equivalence, and can meet the multinomial engine request of prestress engineering.
Summary of the invention
In order to overcome, because FRP twisted wire is long, cause transportation difficulty, overlength duct affects prestressing force and loads effect, the problems such as waste of material that overlap joint prestressing force twisted wire exists, the utility model provides a kind of FRP twisted wire connector, not only can spreading twisted wire, can also transmit the internal force of FRP twisted wire, also can be used as anchored end in the time of as connector, be the connection anchoring element using when cloth muscle, subsection tension are constructed continuously in ultra-long prestressed structure.
The technical solution adopted in the utility model is: a kind of connector that can connect single FRP twisted wire, comprise branch sleeve and Working-Clip sleeve tubular type ground tackle two parts, and described Working-Clip sleeve tubular type ground tackle is positioned at branch sleeve inside, and is threaded with branch sleeve; Described Working-Clip sleeve tubular type ground tackle is annular hollow structure, and FRP twisted wire is positioned at Working-Clip sleeve tubular type ground tackle center, and fits tightly with described Working-Clip sleeve tubular type ground tackle inwall.
Technique scheme, described Working-Clip sleeve tubular type ground tackle comprises intermediate plate, metal sleeve, anchor cup; Described branch sleeve inwall and anchor cup external surface are provided with screw thread, and described branch sleeve is threaded with anchor cup; Described intermediate plate is hollow wedge-shaped structure, and described metal sleeve is sleeved on intermediate plate inside, and the inwall that described intermediate plate contacts with metal sleeve is provided with anti-skid structure, and FRP twisted wire is positioned at the center of metal sleeve; Described anchor cup between intermediate plate for wedge shape is combined.
Technique scheme, described intermediate plate is divided equally three, has the spacing of 1 ~ 2mm between every two.
Technique scheme, described anti-skid structure is the tooth line that is positioned at intermediate plate inwall, described tooth line profile of tooth is inwards.
Technique scheme, described intermediate plate tooth line is 60 ° of angles, and described tooth line spacing is 1mm.
Technique scheme, the wedge shape inclination angle of described intermediate plate is between 3 ° ~ 6 °.
Technique scheme, described intermediate plate tip is provided with chamfering.
Technique scheme, the inner wall smooth of described anchor cup, and wedge shape inclination angle is between 3 ° ~ 6 °.
, between described intermediate plate and anchor cup, there is the differential seat angle of 0.1 ° ~ 0.5 ° in technique scheme.
Technique scheme, described branch sleeve external surface is regular hexagon.
The beneficial effects of the utility model are: (1) the utility model FRP twisted wire connector is considered the laterally weak drawback of shear resistance of FRP material itself, can weaken circumference stress concentrates, improve integrated connection effect, and this FRP twisted wire connector structure is simple, convenient processing, assembling; (2) the utility model branch sleeve external surface is regular hexagon, elegant in appearance, modern design, and be convenient to connect, convenient construction, and can repeatedly reuse.

The specific embodiment
See Fig. 1 to Fig. 7, the utility model FRP twisted wire connector is divided into A, B two parts, A is partly Working-Clip sleeve tubular type ground tackle, comprise anchor cup 5, intermediate plate 2, metal sleeve 3 three parts, there is chamfering 22 the sharper one end of intermediate plate 2, inwall has tooth line 21, and the anchor cup 5 with smooth inner wall is for wedge shape is combined between intermediate plate 2, and both wedge shape inclination angles are all between 3 ° ~ 6 °.For fear of notch effect, between intermediate plate 2 and anchor cup 5, there is the differential seat angle of 0.1 ° ~ 0.5 °, FRP twisted wire 4 is positioned at the center of metal sleeve 3, metal sleeve 3 has avoided intermediate plate 2 directly to clamp FRP twisted wire 4, thereby be unlikely to FRP twisted wire 4 pinch ofves, destroy, anchor cup 5 external surface certain lengths have screw thread; B is partly branch sleeve 1, sees Fig. 6 and Fig. 7, and outward appearance is regular hexagon nut shape, is convenient to connection construction; Inner surface is circular, branch sleeve 1 inwall have screw thread and internal diameter identical with anchor cup 5 external diameters.
See 4 and Fig. 5, preferably, there is chamfering the thinner one end of intermediate plate 2, and divide equally three, between every two, have 1 ~ 2mm spacing, 21 one-tenth 60 ° of angles of intermediate plate 2 inwall tooth line, tooth line 21 spacing are 1mm, and tooth line 21 profiles of tooth inwards, to being housed, the metal sleeve 3 of FPR twisted wire 4 there is good positioning action, to prevent that metal sleeve 3 from outwards skidding off.
FRP twisted wire 4 connector mounting processs are convenient, by coated metal sleeve pipe 3 around FRP twisted wire 4 one end, metal sleeve 3 fits tightly with intermediate plate 2 inwalls, reach anchor cup 5 inside, reserved a bit of length tingle 2 and anchor cup 5, pretension ground tackle, is screwed into respectively branch sleeve 1 two ends by ground tackle and can forms FRP twisted wire connector.Because the effect of metal sleeve 3 has weakened hoop concentrated stress, avoid crushing FRP twisted wire, anchor cup 5 is convenient to manually be screwed in orthohexagonal branch sleeve 1 surface.
