A sleeve pipe pull-out tool and a pull-out lead screw are additionally arranged, the pull-out tool is screwed with the bolt sleeve pipe through a of the thread pull-out tool, the pull-out lead screw ejects the screw, the lead screw is rotated to take a threaded pipe sleeve out of a hole, or the pull-out tool and the step of the bolt sleeve pipe are directly used for taking the bolt sleeve pipe out, and then an expansion bolt is taken out.
Description
Technical field
The present invention relates to a kind of expansion bolt, is characterized in that fastening position easily can be extracted after discarding and repeatedly uses.
Background technology
At present, common expansion bolt construction is by the traction screw of cone-shaped end, expansion sleeve, pad, spring washer, nut.
During use, expansion set is all filled in the circular hole of the go-no-go being drilled on body of wall in advance, constantly tightens nut, strength during use
Expansion set is delivered to by packing ring, pad, center bolt is pulled out against from expansion set, the center bolt end with taper seat design
The spreading of expansion set is made expansion bolt firmly be stuck in circular hole by head.But after fixed position is discarded, due to expansion bolt it is swollen
Deform when being enclosed within fastening and be stuck in hole, simultaneously because expansion set puts forth effort position without external, it is impossible to which expansion set is taken out, so as to cannot
Take out discarded expansion bolt, so as to be exposed to matrix surface, affect matrix surface it is attractive in appearance, while also resulting in the safety of matrix surface
Hidden danger, the single use of expansion bolt also result in ample resources waste.
The content of the invention
It is an object of the invention to provide it is a kind of it is discarded after easily extract, and can reusable expansion bolt external member.
What the present invention was realized in：
The present invention provides a kind of detachable reusable expansion bolt external member, is made up of main part and annex, and main part is to complete
The fastening part of article, increases screw thread or step screw thread in the non-openend of setscrew expansion set, and annex completes tearing open for expansion bolt
Except function.Main part is divided into two big class, and a class is conical screw expansion bolt, and another kind is tapered cup nut type expansion bolt.Taper
Screw type expansion bolt primary structure is made up of four parts：Conehead screw mandrel, threaded or band step screw thread expansion set, plain cushion, packing ring
And nut；Tapered cup nut type expansion bolt is by tapered cup nut, threaded or band step threaded tube, plain cushion, packing ring and spiral shell
Bolt is constituted.Annex by driver-extractor, rise and pull out bolt and constitute.Driver-extractor is Double-ended nut, and threaded one end matches with expansion set external screw thread, separately
Same the rising of threaded one end pulls out the hexagons such as bolt matching, profile, acts primarily as expansion set and screws and the rotation stop pulled out during bolt an is screwed work
With.After fixture is removed, using driver-extractor with the threaded connection of pipe box, rotate and pulled out bolt, expansion set has been taken out, while taking out cone
Shape screw rod or tapered cup nut, complete the removing of securing member and repeat to recycle function.
In the present invention, expansion sleeve is welding materials in the tube or seamless pipe, is easy to the processing of non-openend screw thread.
In the present invention, driver-extractor one end internal thread matches with expansion set screw thread, and same the rising of other end screw thread pulls out bolt matching, rises and pulls out
Bolt can be itself bolt in expansion bolt.
In the installation of a kind of detachable reusable expansion bolt sleeve provided using the present invention, first on body of wall
Punching, its depth exceed expansion bolt length, after fixing object hole with the alignment of body of wall hole, expansion bolt are positioned in hole,
Expansion set exposes surface of wall, less than washer face, tightens nut so as to fixed.
When a kind of detachable reusable expansion bolt external member for being suitable for present invention offer is dismantled, first using spanner
Nut is removed, removes pad, with the end of hammer bolt, made stud base contact body of wall bottom outlet, screwed in using driver-extractor
Expansion set, has screwed in the driver-extractor other end and has pulled out bolt, has rotated and has pulled out bolt, takes out expansion set, and takes out dilating screw in the lump.
The beneficial effect that the present invention reaches：
（1）The detachable reusable expansion bolt external member that the present invention is provided be mainly used in metope fastening in construction,
In engineering in temporary guard rail and road engineering consumable accessory fastening（Deceleration strip and guard rail）, solve construction cost height, road
Road potential safety hazard and flooring-safe hidden danger, provide the repeatable expansion bolt for utilizing for subsequent construction, eliminate safe hidden trouble, increase
Plus body of wall and ground aesthetic property.
（2）A kind of detachable reusable expansion bolt external member that the present invention is provided is that a kind of making is simple, operation
Strong, the reusable expansion bolt external member of property.
