Abstract
A wedge-type anchor rod is composed of wedge block, wedge holder in contact with the inclined surface of wedge block, rod body passing through wedge holder and fixed to wedge block, supporting frame between wedge holder and tray, tray at lower end of rod body, and nut. The lower nut is screwed to pull the wedge block at the upper end to move downwards and apply force to the hole wall in the radial direction, so that the anchoring purpose is achieved. The device can realize integral installation, integral recovery, error correction construction and false construction avoidance, and has the advantages of simple structure, quick installation, low cost and convenient popularization and use.
Description
Technical field
The utility model relates to a kind of anchor pole, a kind of especially wedge-type anchor pole.
Background technology
Patent " easily reclaims anchor pole " (publication number: 2086796) be a kind of modified anchor pole on metal inverted wedge type anchor rod architecture basics.It is made up of nut, last voussoir, lower wedge block, the body of rod, pallet, upper and lower voussoir inserts in the boring hole with iron wire binding back, then with voussoir afterbody in the hammering of special-purpose cover, make between two voussoirs and the hole wall and produce anchored force, the body of rod being passed the through hole of lower wedge block and last voussoir and the nut of last voussoir spins again, the cover mounting plate, fastening nut.It is simple in structure, can be partially recycled.Its weak point is:
1. by the mounting method of iron wire binding, sleeve pipe hammering, its operation is comparatively complicated, can not integral installation, waste time and energy, and anchored force is less, especially to deep hole anchoring difficulty especially.
2. have sillar to stop up in the middle of in the hole, upper and lower voussoir is obstructed midway, and anchoring does not in advance then reach construction requirement in the hammering process.
3. can not all reclaim, can only reclaim the body of rod, supporting plate and nut, voussoir is stayed in the hole.
4. can not error correction construction (when referring to that promptly anchor pole runs into anchoring midway, being intended to the full part of anchor pole is withdrawed from finishing boring, the method that repeats to construct).
The utility model content
The purpose of this utility model be exactly to provide a kind of simple in structure, integral installation, recycled in its entirety, simple installation, can the error correction construction the wedge-type anchor pole.
For achieving the above object, the utility model adopts following technical scheme: comprise the wedge-type anchor pole of voussoir, holder wedge, the body of rod, pallet, nut, its body of rod upper end is passed and is ask wedge to fixedly connected with voussoir, and the inclined-plane of voussoir contacts cooperation with the inclined-plane of holder wedge.Be provided with support between holder wedge and pallet, holder wedge and support are connected as a single entity, and support end in addition contacts with pallet, keeps the space that the body of rod is tilted because of the voussoir radial displacement between the body of rod and the support at least, and the holder wedge is provided with the space that the body of rod is tilted.The holder wedge is made of an inclined-plane at least, and each inclined-plane of holder wedge all has the voussoir to contact cooperation with it, and the inclined-plane of holder wedge is two above structures, the inclined-plane entad and circle distribution, the pole that is connected as a single entity with it is arranged at body of rod top, and fixedlys connected with voussoir respectively.Described support is a pipe fitting; Perhaps mid-stent is a rod member, fixedlys connected with last dish, lower wall respectively in its two ends, and mid-stent is made of a rod member at least.The maximum radius of support is less than boring radius.Described voussoir axial external surface bottom is centroclinal arc surface, and there is chamfering voussoir and holder wedge upper end.Be convenient to install and reclaim.Described voussoir end is welded with the rubble cutter head.
During use, with the bottom in the utility model patchhole, fastening nut makes voussoir to bottom offset, and radially to the tube wall application of force,, make it produce anchored force, and pallet is fastening.The utlity model has following advantage:
1. integral installation.Need not decompose installation, operation is simple, and is quick for installation.
2. recycled in its entirety.As long as unclamp nut, upwards hammering can make voussoir break away from anchoring, and full part is pulled out recovery.
3. can realize the error correction construction.To undesirable anchor pole is installed, can lay down at any time, reuse after the finishing.
4. can avoid false construction.Anchor pole welds because of an end, and tail end is a screw thread, can not saw one section for it, can guarantee construction quality effectively.
5. in case of sillar there being, can using the wedge-type anchor pole that has the rubble cutter head in the hole midway,, go deep at the bottom of the hole to overcome the resistance of rubble.
6. it is simple in structure, is easy to make, and is with low cost

The specific embodiment
With reference to Fig. 1.Comprise voussoir 6, holder wedge 10, the body of rod 2, pallet 3, nut 4, body of rod upper end is passed and is ask wedge to fixedly connected with voussoir, and the inclined-plane 7 of voussoir contacts cooperation with the inclined-plane 8 of holder wedge, is provided with support 1 between holder wedge and pallet, and support is a body.Holder wedge and support are connected as a single entity, and support end in addition contacts with pallet, keeps the space 13 that the body of rod is tilted because of the voussoir radial displacement between the body of rod and the support at least, and the holder wedge is provided with the space that the body of rod is tilted.
With reference to Fig. 2, Fig. 3.Mid-stent is a rod member, fixedlys connected with last dish 11, lower wall 12 respectively in its two ends, and mid-stent is made of a rod member at least, and the maximum radius of support is less than boring radius.
With reference to Fig. 4.The holder wedge is made of an inclined-plane at least, each inclined-plane of holder wedge all has the voussoir to contact cooperation with it, and the inclined-plane of holder wedge is two above structures, and the inclined-plane entad and circle distribution, the pole 9 that is connected as a single entity with it is arranged at body of rod top, and fixedlys connected with voussoir respectively.Described voussoir axial external surface bottom is centroclinal circular arc inclined-plane 14.Described voussoir end is welded with rubble cutter head 15.
