Abstract
The utility model relates to a non-sticking reinforced anchoring head antisepsis device. The utility model is characterized in that the utility model is composed of a end head oil sealing cover A, a PE sleeve pipe B, and a heat shrinkable tube C, wherein, the end head oil sealing cover A is composed of a screw hole 1, an oil injecting hole 2, antisepsis oil 3, and a sealing packing ring 5, and the PE sleeve pipe B is beforehand sheathed on a steel strand. The structure of the utility model is simple, and the utility model can reliably carry out the long antisepsis and the effective antisepsis to the integration of a non-striking reinforced anchoring head part (comprising an anchoring device, steel strand).
Description
The utility model relates to a kind of prestress wire anchor head anti-corrosive apparatus.
In the existing prestressed reinforced concrete structure engineering, bear all on the anchoring tool because unbonded tendon is prestressed, so, very high to the requirement for anticorrosion of anchoring tool and steel strand.But for a long time, the way of all adopt in the termination and apply some antiseptic oils, on every unbonded tendon termination, overlapping a PE cover, this method can play antisepsis in short-term, but the time has been grown, because the erosion of water or air etc., anchoring tool, unbonded tendon are easily by corrosion, to the anchoring of anchoring tool was lost efficacy.
The purpose of this utility model be to provide a kind of simple in structure, and can be reliably to prestressing force unbonded tendon anchor head partly (containing anchoring tool, steel strand) wholely carry out long-time, effective corrosion-resistant unbonded tendon anchor head anti-corrosive apparatus.
For reaching above-mentioned purpose, the unbonded tendon anchor head anti-corrosive apparatus of the utility model by termination oil sealing cover, be enclosed within the outer field PE sleeve pipe of steel strand, heat-shrinkable tube three parts are formed.
Below in conjunction with drawings and Examples the utility model architectural feature is described further.
Accompanying drawing: unbonded tendon anchor head anti-corrosive apparatus structure and user mode reference diagram.
Embodiment:
As shown in drawings, the unbonded tendon anchor head anti-corrosive apparatus of the utility model is by the cover 2 with band screw hole 1 and oil filler point 4, antiseptic oil 3, the termination oil sealing cover A that seal washer 5 constitutes, the PE cover B and the heat-shrinkable tube C that are enclosed within on the steel strand 6 constitute, during use, PE is overlapped B and heat-shrinkable tube C is enclosed within on the unbonded tendon 6 in advance, after stretch-draw finishes, excision stretch-draw end or the unnecessary steel strand of fixed end, stay the 30mm-50mm termination, termination oil sealing cover A covered link with screw behind the termination or be bonded on the work anchor slab 9, PE is overlapped B to be sent in work anchor slab 9 holes, heat hot collapsible tube C makes its PE that wraps unbonded tendon cover B and PE layer 8 (referring to Fig. 1), irritate antiseptic oil 3 with pressure then, the exposed parts long period of soaking that makes work clip sheet 7 and unbonded tendon 6 in antiseptic oil 3, thereby reach long-term antisepsis.
The utility model apparatus structure is simple, easy to use, has solved preferably to carry out long-time, effective corrosion-resistant problem to the unbonded tendon anchor head is whole, is specially adapted to whole anticorrosion to unbonded tendon annular ground tackle anchor head.
