The present invention relates to a kind of portable prestressed anchors, including doughnut body, axially disposed on anchor body to have cylindrical hole, are provided with rotary table on the cylindrical hole of anchor body both ends of the surface.Further include the arc groove that the cylindrical hole two sides of anchor body are set, insert the arc fixed block in the arc groove, the cylinder being plugged on the cylindrical hole is provided with the oval compression boss that can rotate press arc fixed block in the rotary table on the cylinder.Prestressed anchor provided by the present invention is simple, convenient locking and absent-mindedness steel hinge line, improves 20 times or more than traditional handicraft, relaxes the steel hinge line working time after improvement and is no more than 3 seconds, traditional handicraft then needs 60 seconds or more；If prestressing force is excessive, under working instrument anchor can not may just be relaxed, directly scrap, and anchorage of the invention is then easy to operate, convenient, safe.
Description
Technical field
The invention belongs to engineerings to build anchorage equipment technical field, and in particular to a kind of portable prestressed anchor.
Background technique
Prestressed anchor is mainly in Process of Engineering Construction, the anchorage of concrete pre-stress tensioning.Generally applied in bridge
It is often used in work, installs positioning in advance, then casting concrete, be embedded in the both ends of concrete, that is, the two of bellows
A end is the end face being arranged for the stabilization of jack when tensioning.
The anchorage used in construction can be divided into two classes:
(a) stretching end anchorage:, which being mounted on presstressed reinforcing steel end, and can open anchorage is also referred to as prestressed anchor, so-called anchorage,
It is in post stretching structure or component, to keep the pulling force of presstressed reinforcing steel and passing it to the mixed anchorage drawn.
(b) fixing end anchorage: being mounted on presstressed reinforcing steel end, in usual Transducers Embedded in Concrete and not to the anchorage of tensioning.
Be widely used in highway bridge, railroad bridge, city intersection, urban light rail, skyscraper, water conservancy and hydropower dam,
Port and pier, the anchoring of rock mass slope protection, strengthening of foundation, tunnel mine top anchor top, prestressed space grids, subway, large-scale office building, auditoriums, hotels, warehouse
Workshop, point building, heavy lift, the propulsion of synovial membrane interval, bridge tunnel pushing tow, large container and ship, sleeper, replacement bridge branch
Seat, reinforced bar engineering, antimagnetic and antiseptic project (fiber anchorage), carbon fiber reinforcement, is first opened Liang Chang and is applied bridge and building strengthening
In the projects such as work, external prestressing engineering, suspension cable, suspension cable.But existing prestressed anchor has the following problems:
1, when existing working instrument anchor is relaxed, artificial backward hammer blow working instrument anchor edge is needed, thus can artificially be hammered onto steel hinge often
Line, jack, working instrument anchor can also accidentally injure operator sometimes；
2, there is direct relation in the time required for existing working instrument anchor is relaxed with prestressing force is applied, and application prestressing force is bigger, required
Time it is longer, it could even be possible to can not ease up, if prestressing force is excessive, under working instrument anchor can not may just be relaxed,
Directly scrap；
3, existing working instrument anchor installation is more troublesome, and needs worker to carry out using tools such as hammers, and expend and realize.
Invent a kind of portable prestressed anchor art scheme urgently to solve above-mentioned technical problem.
Summary of the invention

Specific technical solution is: a kind of portable prestressed anchor, including doughnut body are set on the anchor body along axial direction
It is equipped with cylindrical hole, is provided with rotary table on the cylindrical hole of the anchor body both ends of the surface.
It further include the arc groove that the cylindrical hole two sides of anchor body are set, the arc groove is axially opened up along anchor body, described
The first semicircle orifice of interspersed steel wire is provided on arcwall face on arc groove far from cylindrical hole.
It further include the arc fixed block inserted in the arc groove, corresponding first semicircle orifice is opened on the arc fixed block
Equipped with the second semicircle orifice.
It further include compact heap, the compact heap includes the cylinder being plugged on the cylindrical hole, is arranged on the cylinder
There are the oval compression boss that press arc fixed block can be rotated in the rotary table.
First semicircle orifice and the second semicircle orifice are combined to form the threaded hole of steel of interspersed steel wire.
It further, further include ratchet knob block, the ratchet knob block is vertically set on one end face of cylinder.
Further, guide groove, the corresponding guiding are additionally provided on the arcwall face on the arc groove far from cylindrical hole
Slot is provided with guide ledges on the mounting surface of arc fixed block and arc groove.
Further, further include agreeing with the anchorage lid for being mounted on the anchor body both ends of the surface, cover corresponding steel wire in the anchorage
Hole offers steel wire cap bore, and corresponding compact heap is provided with compact heap cap bore.
Beneficial effects of the present invention:
1, not damaged formula absent-mindedness working instrument anchor and steel hinge line；
2, simple, convenient locking and absent-mindedness steel hinge line；
3,20 times or more are improved than traditional handicraft, the steel hinge line working time is relaxed after improvement no more than 3 seconds, traditional handicraft then needs
60 seconds or more；
4, anchorage is easy to operate, convenient, safe.
