Description
Technical field
The invention belongs to engineering construction technical field, in particular to a kind of stretching end anchorage for anchorage cable anchoring.
Background technique
Stretching end anchorage installation can remain its anchor in the stretching end of presstressed reinforcing steel in the stretching process of presstressed reinforcing steel
Solid fraction state.When in use, first guidance presstressed reinforcing steel passes through anchor slab, intermediate plate is placed in anchor slab taper hole, then tensioned prestressing bar,
Presstressed reinforcing steel elongation, after removing tensioning external force, presstressed reinforcing steel will bounce back and drive position in the taper hole of the presstressed reinforcing steel in the same direction of intermediate plate one
It moves, to clamp presstressed reinforcing steel, realizes the reliable anchoring of presstressed reinforcing steel.
Presstressed reinforcing steel generallys use steel strand wires, and the antiseptic property of steel strand wires will directly affect prestressed maintenance and use the longevity
Life.In the prior art, presstressed reinforcing steel generallys use the steel strand wires with PE oversheath, and the PE oversheath can not be engaged with intermediate plate,
Therefore the presstressed reinforcing steel in intermediate plate occlusion fixed section must be completely stripped the PE oversheath of steel strand wires periphery cladding.PE oversheath
Strip calculating of the length based on steel strand wires stress elongation percentage, but the actual elastic modulus of material and theoretical elasticity modulus have difference
It is different, so that there are deviations for the calculating elongation percentage and practical elongation percentage of steel strand wires, to influence the precision of PE stripping outer jacket length.
Due to the too short general of PE stripping outer jacket section so that PE oversheath enters intermediate plate occlusion section, cause intermediate plate that can not sting with presstressed reinforcing steel
It closes, steel strand wires will be deviate from from anchorage under stress, cause the major accidents such as construction instrument damage even casualties.
Therefore, when construction at present, based on security considerations, longer PE oversheath can be stripped, then by increasing outside intermediate plate and anchorage
The mode of coupling tube or sealing drum is arranged in the outer end face of anchor slab or anchor plate such as to realize on the outside of anchorage in the spacing of end face
It is complicated to anchor at high cost and construction for the anti-corrosion of exposed steel strand wires.
The information for being disclosed in the background of invention technology segment is merely intended to deepen the reason to general background technique of the invention
Solution, and it is known to those skilled in the art existing to be not construed as recognizing or imply that the information is constituted in any form
Technology.
Summary of the invention
The purpose of the present invention is to provide a kind of stretching end anchorages, can be simple while compensating stripping outer jacket error in length
Change anchor device structure.
In order to achieve the above object, the technical solution adopted by the present invention are as follows: a kind of stretching end anchorage, including anchor slab, on anchor slab
Equipped with the anchor hole passed through for presstressed reinforcing steel, the inner end of anchor hole is the taper hole that outside is big, inside is small, the periphery of taper hole and intermediate plate
Shape is consistent, and the front end of taper hole, which is equipped with, constitutes blocking surface against cooperation with the end face of the oversheath of presstressed reinforcing steel, on blocking surface
It is passed through equipped with hole for steel strand wires.
With need to strip longer oversheath in the prior art on the contrary, the present invention only needs to strip shorter outer shield when in use
Set, in tensioned prestressing bar, blocking surface is displaced terminal as oversheath end face, oversheath is limited on the outside of taper hole, effectively
Oversheath is prevented to enter security risk caused by taper hole.Meanwhile the steel strand wires of presstressed reinforcing steel are just in exposed within blocking surface
State need to only guarantee the antiseptic property at blocking surface in this way, can be achieved with the reliable anti-corrosion of exposed steel strand wires, to greatly simplify
The anti-corrosion structure of presstressed reinforcing steel.

Specific embodiment
With reference to the accompanying drawing, by the description of the embodiment, making further specifically to a specific embodiment of the invention
It is bright.
For convenient for narration, anchor hole 11 is denoted as outer end for the one end for entering anchor slab 11 presstressed reinforcing steel A, will anchored by the present invention
Hole 11 is pierced by anchor slab 11 for presstressed reinforcing steel A and the one end cooperated with intermediate plate 20 is denoted as inner end.Presstressed reinforcing steel A includes steel strand wires A1,
The periphery of steel strand wires A1 is arranged with oversheath A2, and oversheath A2 has good elastic property.
A kind of stretching end anchorage, including anchor slab 10, anchor slab 10 are equipped with the anchor hole 11 passed through for presstressed reinforcing steel A, anchoring
The inner end in hole 11 is the taper hole 111 that outside is big, inside is small, and taper hole 111 is consistent with the peripheral shape of intermediate plate 20, before taper hole 111
End is equipped with the blocking surface 112 with the end face of the oversheath A2 of presstressed reinforcing steel A composition against cooperation, and blocking surface 112 is equipped with hole
It is passed through for steel strand wires A1.
In the specific implementation, the oversheath A2 that length is less than steel strand wires A1 elongation is stripped, exposed steel strand wires A1 is worn
Anchor hole 11 is crossed, then tensioned prestressing bar A, presstressed reinforcing steel A stress extends, and the end face of oversheath A2 is therewith to blocking surface 112
The displacement of place side.Oversheath A2 generallys use nonmetallic materials, has good elastic property, in oversheath A2 and blocking surface
Continue tensioned prestressing bar A after 112 fittings, oversheath A2, which is pressurized, occurs elastic deformation, is blocked face 112 and is blocked in taper hole 111
Outside, so that effectively avoiding oversheath A2 from entering taper hole 111 influences operation safety.The end face of oversheath A2 can be and oversheath
A2 axial direction is at the arbitrary face of angle, and when the end chamfer of oversheath A2, chamfering also constitutes the one of the end face oversheath A2
Part, blocking surface 112 can be consistent with the end face of oversheath A2, or along the radial direction arrangement of anchor hole 11, as long as 112 energy of blocking surface
The end face enough and oversheath A2 is connected and oversheath A2 is prevented to enter taper hole 111 and just can protect operation safety.
Preferably, retaining ring 12 is equipped at the inner wall of 11 outer end of anchor hole and/or at opening's edge, the outer end face of retaining ring 12 is constituted
The end face of the oversheath A2 of blocking surface 112 and presstressed reinforcing steel A are against cooperation, the steel of the middle part hole of retaining ring 12 for presstressed reinforcing steel A
Twisted wire A1 is passed through.In this case, retaining ring 12 is passed through for steel strand wires A1 and is connected with protective jacket A2, meanwhile, retaining ring 12 is pressurized
Deformation and anchor hole 11, presstressed reinforcing steel A constitute sealing cooperation and are also avoided that anti-corrosion medium reveals caused anti-corrosion and fails, i.e. retaining ring
12 had not only realized the safe and reliable tensioning of presstressed reinforcing steel A, but also simplified its anti-corrosion while guaranteeing presstressed reinforcing steel A antiseptic property
Structure.
