Description
Technical field
It is specially a kind of readily removable to remove and repeatable utilize expansion bolt the present invention relates to technical field of fastening.
Background technology
Expansion bolt is a kind of anchor for the installation that can be drilled on existing building.During installation, expansion bolt is put
Enter in the drilling of existing building, screw rod is pulled out by tightening nut, the iron sheet pipe with cut ends is passively outwards opened
Open so that screw rod conehead applies the normal pressure perpendicular to hole wall to conduit peschel, so as to produce certain withdrawal resistance, reaches anchoring mesh
's.
It is deep to be welcome by engineering circles because expansion bolt is cheap, install convenient.But undeniable to be, existing expansion
Bolt, which exists, removes the problem of difficult so that exposed shank of bolt, which is not easy to be blocked, covering and easily to get rusty, influence it is attractive in appearance, even if by force
Row is pulled out and can not also reused.
The content of the invention
The present invention carries to solve the problems, such as existing expansion bolt in the presence of that can not be reused after being not easy to remove and removing
Supply a kind of readily removable to remove and repeatable utilize expansion bolt.
The present invention adopts the following technical scheme that realization：It is a kind of it is readily removable remove and it is repeatable utilize expansion bolt, it is including swollen
Swollen bolt body and dismounting mechanism：Expansion bolt body includes screw rod and the expansion tube being enclosed on the outside of it, and the left part of screw rod is set
The nut being threadedly coupled with it is equipped with, the right-hand member of screw rod is provided with right side diameter and is more than left side diameter and more than expansion bore
Taper boss, the left end of expansion tube are provided with integral and on the outside of it pad I with it, and expansion tube lateral wall, which is provided with, to be located at
On the right side of pad I and external diameter is more than the pad II of mounting hole internal diameter, and pad I external diameter is more than pad II external diameter, the right side of expansion tube
End sidewalls are provided with some axially arranged bar-shaped troughs, and the spring washer being enclosed on screw rod is provided between nut and pad I；Tear open
Include two pry heads at the step of insertion pad I and pad II formation except mechanism, the outer end of two pry heads is provided with and its one
And the pry handle being symmetrical set, the connecting rod that one end is hinged with its be hinged, other end is provided with the middle part of two pry handles,
The lower end of two pry handles is provided with the connector integral with it, is provided with rubber roll on two connectors, and two connectors
Adjacent one end is provided with the horizontal groove that pry head outer end is inserted in it, and opposite one end of two connectors, which is screwed with, penetrates horizontal groove
And the fixing screws being threadedly coupled with pry head.
During installation, suitable drill bit is selected according to the length of expansion tube and external diameter, in building stationary plane injection mounting hole,
Expansion bolt is inserted into mounting hole, pulls screw rod to be moved to mounting hole direction by tightening nut, forces taper boss
Enter in the expansion tube with bar-shaped trough, expansion tube right-hand member is produced axial crushing deformation, opening portion by the effect of axial force
Expand outwardly, extruding installation hole wall, enough normal pressures are provided for resistance to plucking resistance after taper boss is superimposed with expansion tube thickness, real
The fastening of existing expansion bolt；
When need remove when, first by nut unscrew and be screwed to it is concordant with screw rod left end, using hand hammer touch screw head, force
Taper boss is exited from expansion tube, and now, nut is backed out from screw rod, and both sides pry head is inserted into pad I and pad II
At the step of formation, pry head is set to clamp expansion tube, then both hands push pry handle simultaneously, and pry handle is using rubber roll as fulcrum, i.e.,
Expansion tube can be extracted out of mounting hole, as expansion tube is gradually extracted, pry head slip occurs with pad I and even results in cunning
Sled, but rubber roll moves to expansion bolt side in the presence of lower pressure horizontal component, can effectively prevent sled, expansion bolt
It is reusable that simple finishing is passed through after dismounting, and overcoming after existing expansion bolt presence is not easy to remove and removed to repeat
The problem of utilization.
Remove mechanism and replace with following mechanism：Including ripping bar, support pier and fixture, ripping bar is by tilting section pole and level
Section pole is integrally formed, and the upper end of the infall and support pier of tilting section pole and horizontal segment pole is hinged, horizontal segment branch
The left end of bar is provided with the ripping bar axle of front and rear distribution, and fixture includes two be hinged clamping bars in middle part, and the upper end of two clamping bars is all provided with
Steel wire rope node is equipped with, the lower end of two clamping bars, which is provided with to its inner side extension and insertion pad I and pad II, forms step
The horizontal brace rod at place, grip block is provided with the inside of two horizontal brace rods, ripping bar axle is circumscribed with two steel wire rope nodes
The steel wire rope of closing.
When carrying out dismounting operation, grip block is inserted at the step of pad I and pad II formation, pull down ripping bar, prized
The horizontal segment pole of bar is rotated clockwise using the pin joint of support pier as axle, so drive steel wire rope pull fixture two clamping bars to
Inner side is withdrawn, and grip block and pad II clampings is effectively prevented sled；Continue to pull down ripping bar, make in the flexibility of steel wire rope
Under, a upward pulling force is applied to expansion tube, most it is extracted out of mounting hole at last.
The present invention is simple in construction, reasonable in design, coordinates removal tool by improving existing expansion bolt structure optimization
Exploitation, a kind of easy to disassemble and recycling expansion bolt being obtained, unloading process is convenient and swift, is not limited by dimensional orientation,
It ensure that mounting hole site surface may be repeated utilization without hard damage, and the expansion bolt by repairing, save a large amount of
Cost, there is the advantages of processing is simple, the time saving and energy saving and cost of operation is low.
