Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Fig.1, is a kind of concrete bridge construction prestressed anchor disclosed by the utility model, including anchor slab 1, anchor pad
Plate 2, more cable wires 3.Anchor slab 1 is used for fixing tightwire 3, and anchor plate 2 is used to support anchor slab 1, and the power that anchor slab 1 is subject to is transferred to
At concrete structure.
Anchor plate 2 is equipped with spiral bar 4 away from the plate face of anchor slab 1, is arranged with bellows 5 outside the cable wire 3 in spiral bar 4,
All cable wires 3 are wrapped in interior by bellows 5.When casting concrete, spiral bar 4 is fixed in concrete, and spiral bar 4 is for improving
The compression strength of concrete after anchor prevents concrete under anchor from local failure occurs under the action of tension stress.Bellows 5 is used for
Pore-forming, convenient for the lashing of cable wire 3.
Referring to Fig. 2 and Fig. 3, anchor slab 1 is cylinder, offers multiple mounting holes 11 passed through for cable wire 3 on anchor slab 1, is pacified
The aperture for filling hole 11 is tapered towards 4 direction of spiral bar, axis circumferentially array distribution of all mounting holes 11 about anchor slab 1.Often
It is respectively provided in a mounting hole 11 there are three intermediate plate 12, three intermediate plates 12 are identical, simultaneously can form rotary table, rotary table by combination
Lateral wall it is tapered, the inclined direction of taper is corresponding with mounting hole 11.Three intermediate plates 12 are circumferentially surrounded in outside cable wire 3,
Intermediate plate 12 is offseted by the inner wall of outer wall and mounting hole 11.Intermediate plate 12 contacts fixation with cable wire 3 by stiction, when cable wire 3
When moving along the direction of anchor slab 1 towards spiral bar 4, the mounting hole 11 of taper forces in intermediate plate 12, and intermediate plate 12 is generated to 3 side of cable wire
To mobile trend, intermediate plate 12 can be reliably clamped cable wire 3.
Anchor slab 1, which is used to dismount, offers thread groove 13 in the plate face of intermediate plate 12, the quantity and mounting hole 11 1 of thread groove 13
One is corresponding, and the axis of thread groove 13 is overlapped with the axis of mounting hole 11, and thread groove 13 is annular groove, and inner ring surface is screw thread.Often
Pressing sleeve 6 is threaded on a thread groove 13, pressing sleeve 6 includes the abutment ring 61 for abutting 12 end of intermediate plate, abutment ring 61
Lateral wall be regular hexagon, the inner ring of abutment ring 61 passes through for cable wire 3.Pressing sleeve 6 is divided into two semiorbicular sub-sets, abuts
Ring 61, which is divided to, to be located at two sons for two parts and puts on, and to form cylindrical pressing sleeve 6 whole by mutually fastening for two sub-sets.Thread groove 13
Just it can be embedded in for pressing sleeve 6, the external annulus sliding contact of the lateral wall and thread groove 13 of pressing sleeve 6.
After cable wire 3 is installed on anchor slab 1 by intermediate plate 12, personnel can tighten pressing sleeve 6 in thread groove 13, and pressing sleeve 6 is logical
Cross abutment ring 61 push against in 12 end of intermediate plate, then when cable wire 3 is moved along the direction of spiral bar 4 towards anchor slab 1, intermediate plate 12 due to
It is limited by pressing sleeve 6, then cable wire 3 can move simultaneously together with intermediate plate 12, anchor slab 1, and intermediate plate 12 will not be fallen from mounting hole 11, this is pre-
The spontaneous the case where falling of intermediate plate 12 is less prone to when stress anchorage installation, the installation of anchorage is more convenient.
Since pressing sleeve 6 can be installed on outside cable wire 3 by way of fastening, then when wearing cable wire 3 on anchor slab 1, without general
Cable wire 3 is previously threaded through pressing sleeve 6, and pressing sleeve 6 can fill later；When the length that cable wire 3 stretches out anchor slab 1 is longer, pressing sleeve 6 also can be easily
It is installed.The 61 energy convenient wrench clamping of abutment ring of regular hexagon, personnel can reliably be tightened pressing sleeve 6 by spanner.
Anti- DNA releaxed circular DNA 7 is also threaded on anchor slab 1, anchor slab 1 establishes screw thread company by cylindrical lateral wall and anti-DNA releaxed circular DNA 7
It connects, anti-DNA releaxed circular DNA 7 can be realized with anchor slab 1 and be dismounted.Anti- DNA releaxed circular DNA 7 includes the fastening plates 71 of annular, and the interior collar extension of fastening plates 71 is for supplying
All cable wires 3 pass through, and fastening plates 71 are abutted with the demitoroidal of all abutment rings 61.After tightening anti-DNA releaxed circular DNA 7 on anchor slab 1, tightly
Solid plate 71 can play the role of preventing pressing sleeve 6 from loosening, and further increase the stability of intermediate plate 12.The outer wall of anti-DNA releaxed circular DNA 7 is circumferentially
It is provided with non-slip texture 72, hand is not easy to skid when personnel rotate anti-DNA releaxed circular DNA 7.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
