This connector has higher reliability and durability.
Description
Technical field
This utility model belongs to bridge, technical field of buildings, relates to the connection of section construction presstressed reinforcing steel, specifically refers to anticorrosion, durable prestressed steel bar screw thread coupling.
Background technology
Current conventional concrete continuous beam, the firm structure of T beam, for easy construction, many employing section construction modes, again because prestressed steel bar Dou Shi factory scaleization produces, for the ease of transport, length is usually no more than 12.5 meters, so, for the civil engineering of overlength continuous structure or bigger, the presstressed reinforcing steel of its laying needs spreading.The mode of spreading has welding and connects two kinds by adapter, butt welding must adopt large-scale special fixture and set up rod iron fixed support, concentricity and the glacing flatness of docking rod iron can be ensured, being limited by rod iron peripheral space, design, installation are used for the special fixture of built-in rod iron welding and support difficulty is big, speed of application slow, difficult quality guarantee；Adapter is easy to connect reliably, but existing adapter is all the docking effect considering adapter, and adapter is placed in concrete, long-term corrosion, it is easy to lost efficacy, and then cause that prestressed steel bar lost efficacy, part being installed additional to the adapter of sheath, because not sealing, its protection effect is also inconspicuous.
Summary of the invention
This utility model is for the ease of construction and improves the reliability that prestressed steel bar connects, devise a kind of prestressed steel bar anticorrosion adapter, the two sections of rod iron terminations docked by threaded cylinder and connecting cylinder are carried out preserving and sealing, improves reliability and the durability of adapter.
The technical solution of the utility model is: a kind of prestressed steel bar anticorrosion adapter, including the female thread connecting cylinder that two ends are connected with upper and lower rod iron respectively, it is critical only that: the outside of described connecting cylinder is provided with protective jacket, the bottom of protective jacket seals by backing plate or surrounding member, top seals by closure, being provided with, in closure and backing plate or surrounding member, the through hole allowing upper and lower rod iron traverse, the annular seal space indoor between protective jacket and closure, backing plate or surrounding member, upper and lower rod iron and connecting cylinder add and are filled with anticorrosion medium.
The beneficial effects of the utility model are: screw in two sections with externally threaded rod iron link and dock in female thread connecting cylinder and by protective jacket, upper closure, lower bolster and anticorrosion medium, two rod iron terminations and connecting cylinder are carried out preserving and sealing, make prestressed steel bar, adapter and air insulated, long-term corrosion is avoided to cause that prestressed steel bar and adapter lost efficacy, significantly improve reliability and the durability of adapter, there is higher bonding strength and antiseptic effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In accompanying drawing, 1 is connecting cylinder, and 1-1 is positioning table, and 2 is closure, and 3 is protective jacket, and 4 is location nut, and 5 is backing plate, and 6 is upper rod iron, and 7 is lower rod iron, and 8 is surrounding member, and 9 is anticorrosion medium.
Detailed description of the invention
A kind of prestressed steel bar anticorrosion adapter, including the female thread connecting cylinder 1 that two ends are connected with upper and lower rod iron 6,7 respectively, it is critical only that: the outside of described connecting cylinder 1 is provided with protective jacket 3, the bottom of protective jacket 3 seals by backing plate 5 or surrounding member 8, top seals by closure 2, being provided with, in closure 2 and backing plate 5 or surrounding member 8, the through hole allowing the traverse of upper and lower rod iron 6,7, the annular seal space indoor between protective jacket 3 and closure 2, backing plate 5 or surrounding member 8, upper and lower rod iron 6,7 and connecting cylinder 1 add and are filled with anticorrosion medium 9.
Closure 2 be that taper, less conehead push in protective jacket 3, and the external screw thread link of upper rod iron 6 passes its reserved through hole and is connected with connecting cylinder 1.
Surrounding member 8 or backing plate 5 weld or by being threaded in bottom protective jacket 3, and the external screw thread link of lower rod iron 7 is connected through the reserved through hole of surrounding member 8 or backing plate 5 with connecting cylinder 1.Backing plate 5 and protective jacket 3 adopt and weld or threaded ensure that anticorrosion medium 9 does not spill over.When protective jacket 3 is threadeded with backing plate 5, backing plate 5 screws in and is provided with the external screw thread coordinated with protective jacket 3 on protective jacket 3 inner bottom, outer peripheral face.When employing is welded to connect fixing, backing plate can be saved, protective jacket 3 is directly welded together with surrounding member 8.
Anticorrosion medium 9 is unbonded prestressing tendon anti-corrosion grease.When this adapter is for unbonded prestressing tendon, the internal prestressed steel bar of adapter carries out anticorrosion by the preservative injected in adapter；Rod iron outside adapter is by applying anti-corrosion grease and carrying out anticorrosion in outside wrap jacket on barred body.
It is provided with positioning table 1-1, it is possible to ensure effective screwing length when two rod irons connect, to realize high standard, high-quality docking between the two sections of female threads being connected with upper and lower rod iron 6,7 respectively in connecting cylinder 1.
The location nut 4 of the external screw thread link traverse allowing lower rod iron 7 it is provided with, so that lower rod iron 7 to be positioned or locking between backing plate 5 and connecting cylinder 1.
When being embodied as, with reference to accompanying drawing, backing plate 5 or surrounding member 8 are inserted in lower rod iron 7 termination and connecting cylinder 1 are screwed on lower rod iron 7, it is threaded to positioning table place → will closure 2 links that penetrate into upper rod iron 6, also protective jacket 3 is penetrated into the other end of the link of upper rod iron 6 → screwed in by the link of upper rod iron 6 connecting cylinder 1 simultaneously, is threaded to positioning table place → protective jacket 3 and backing plate 5 are screwed or be welded and fixed with surrounding member 8 → inject anticorrosion medium 9 → finally closure 2 be pushed in protective jacket 3 and seals.Integral tension after first two sections of rod irons can being connected when carrying out prestressed stretch-draw, it is possible under pretensioning, rod iron 7 connects integral tension again.
