Abstract

The utility model cone plug type floating anchor device for a centralized anchor sheet, which is characterized in that the utility model is composed of an anchor ring 2 and a centralized clamping sheet 1 of a cone plug, wherein, the circumference of the centralized clamping sheet 1 of the cone plug is uniformly distributed with arc-shaped grooves with tooth-shaped antislip faces, and a clamping mouth which can cause a steel strand to be floated on the circumference and to be vertically fixed is formed by the centralized clamping sheet 1 and the anchor ring. Because of the structure, the utility model has the characteristics of full float and self center adjustment. The utility model overcomes the defect in braiding and bundling steel strands, and causes the steel strands to be uniformly stressed. The utility model has the advantages of convenient operation and reliable and safe anchor fixation.

Description

Male cone type is concentrated the unsteady ground tackle of anchor sheet

The utility model relates to the ground tackle in the building prestress anchoraging engineering, particularly a kind of being applicable to compiling the unsteady ground tackle of the concentrated anchor sheet of male cone type that the bundle steel hinge line carries out prestressed stretch-draw.

In the prestress anchoraging engineering, all ground tackles are based on clip type.This kind ground tackle does not have from loosening function, so can't make in the stretch-draw that to loosen curve entirely be full strain-contain anchoring section flow.Loosen device though abroad be equipped with special use, complex structure, technical requirements is higher, and price is expensive, and domestic still do not have a production of units, more do not see application.

Also have the tapered ground tackle of a kind of KT-2 type in the prior art, though possess from loosening performance, the locking function of its wedge type folder is still not as clip type.More than two types of ground tackles can't regulate automatically each root steel strand unbalance stress phenomenon, though the available single tendon stretch of clip type remedy, operate very cumbersome, poor effect.Steel hinge line is compiled intrafascicular defective, and the two all can't remedy, this is because when the cast steel hinge line is compiled bundle, can not accomplish circumferentially uniform, sometimes even in the shape of a spiral shape, carrying out making each root steel hinge line unbalance stress when anchoring stretches like this, and causing the safety factor of steel hinge line big, the prestressing force that has is not enough, influence workmanship, and cause the waste of steel hinge line.

The purpose of this utility model is to provide a kind of full floating, from aligning, can overcome because steel hinge line is compiled intrafascicular deficiency, make steel hinge line have the problem of discontinuity, and easy and simple to handle, anchoring reliable and secure male cone type is concentrated the anchor sheet ground tackle that floats.

Above-mentioned purpose of the present utility model, be to realize by such technical scheme: promptly a kind of male cone type concentrates the unsteady ground tackle of anchor sheet it is characterized in that: concentrate intermediate plate to form by anchor ring, tapered plug, wherein, be evenly equipped with the deep-slotted chip breaker that has the profile of tooth non slip surface on the circumference of the concentrated intermediate plate of tapered plug, it and anchor ring constitute can make steel hinge line 10 circumference float and vertical fixing clamp port.

Said structure of the present utility model can further specify by the non-limiting embodiment that accompanying drawing provides.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the utility model cross-sectional view;

Accompanying drawing 2 is concentrated the vertical view cutaway drawing of intermediate plate for the utility model tapered plug;

Accompanying drawing 3 is the utility model user mode section reference view.

Referring to accompanying drawing 1,2, the utility model male cone type concentrates the unsteady ground tackle of anchor sheet to concentrate intermediate plate 1 to form by anchor ring 2, tapered plug, wherein, be evenly equipped with the deep-slotted chip breaker that has the profile of tooth non slip surface on the circumference of the concentrated intermediate plate 1 of tapered plug, it and anchor ring constitute can make steel hinge line 10 circumference float and vertical fixing clamp port.In order to reduce the friction factor of anchor ring inner conical surface, the inner conical surface of anchor ring is shiny surface or has smooth layer.

Referring to accompanying drawing 3, the utility model not only can be used as moveable anchor but also can be used as work anchor, and the upper end is a moveable anchor among the figure, and the lower end is a work anchor.Its installation is such: the work anchor that will be installed with steel hinge line 10 is installed on the location-plate 12; The anchor ring 2b of work anchor is fixing by the pressure-bearing retainer ring on it 8, by the oil cylinder 6 of pressure-bearing locating ring 7 setting pressure machines, by positioning sleeve 3 beam splitter 5, anchor restorer 4 and moveable anchor is installed on it on the pressure-bearing retainer ring.Operating principle is such: touch moveable anchor before the stretch-draw and concentrate intermediate plate 1a, the tooth of intermediate plate and the consistent steel hinge line that clamps of anchor ring 2a inner conical surface, because anchor ring and little (special use is retouched and executed) intermediate plate of steel hinge line frictional force and steel hinge line engages fixed, friction greatly, nothing relatively moves, when the jack of oil cylinder moves up and carries out stretch-draw, concentrate intermediate plate 1a to avoid with steel dumpling line is both down tight moving that KT-2's fly the anchor phenomenon, in ring, do the revolution of floating again, can remedy and compile intrafascicular distortion, the stressed size of each root steel dumpling line can be regulated and homogenising again automatically simultaneously, (stressed big person will concentrate intermediate plate to push little direction to) finished and circumferentially floated and radial floating---full floating, to give full play to the function of steel dumpling line and anchor system.When oil cylinder returns zero, as concentrated intermediate plate 1b in the work anchor and steel dumpling line, between anchor ring or relaxation state (and can not go into do not glided) by tape thus system return safely in addition, can make full strain curve, when need are locked, as long as hold the stretch-draw oil cylinder, the top oil cylinder drives 9 actions of top anchor device, the concentrated intermediate plate 1b of work anchor can be pushed the location, intermediate plate is with in the engaging-in steel dumpling line, with system's anchoring reliably.

The good effect that the utility model is produced owing to described structure is: this technology is to prestressed anchor Gu engineering significance is great. The problem of entirely loosening that it can not only solve in the stretch-draw effectively is beneficial to anchoring System carries out full test and monitoring; And because of its full floating, Self-aligning, it is intrafascicular both to have overcome volume Foot can make again steel dumpling line stressed evenly, and easy and simple to handle, and anchoring is reliable and secure. Can more give full play to the steel dumpling The function of line and whole anchor system is conducive to the foundation of anchoring technological procedure system, to stop because of ground tackle The engineering project disaster that lost efficacy and caused. Therefore will promote to give the stress anchoring engineering and more develop by leaps and bounds, be me Modernization construction make useful contribution.
