Technical field
The utility model belongs to rebar connecting technology field, is specifically related to the instrument of a kind of tapered sleeve locking type steel bar connector and field joint.
Background technology
At production fields such as buildings, often metal wire rod need to be connected, for example, in building operations, usually can run into interconnective problem between reinforcing bar, generally adopt welding manner, the end of adjacent two reinforcing bars is welded and fixed together, when welding, need to use welding equipment, job site, often in work high above the ground, is subject to job site spatial limitation, use welding equipment difficulty very large, have huge potential safety hazard, welding consumes mass energy, and environment is caused to very large pollution; And the interface of welding is firm not, gets rusty easily, snaps.
In recent years, occurred that one exempts from welded reinforcement linkage, this device is threaded connection, by adjacent two end reinforced hitch screw threads, by long nut, two ends are connected, the mode complex process being threaded, needs prior or on-the-spot hitch screw thread, use reinforcing bar hitch screw thread special equipment, still have potential safety hazard, in addition because reinforcing bar is longer, therefore hitch screw thread is wasted time and energy, production efficiency is low, cost is high, has limited it and has applied.
Utility model content
The above-mentioned technical problem existing in order to overcome prior art field, the purpose of this utility model is, a kind of tapered sleeve locking type steel bar connector and erecting tools thereof are provided, easy for installation, efficient, handling safety connect reliably, and cost of production is low.
Described tapered sleeve locking type steel bar connector, it comprises tapered sleeve and lock sheet groups, and described tapered sleeve is a pair of, and inner chamber is taper, and described lock sheet groups external surface is shuttle shape, inner surface is provided with locking teeth groove, and a pair of tapered sleeve symmetry is sleeved in lock sheet groups.A pair of tapered sleeve is set, adopts the method for extruding tapered sleeve, by the effect of tightening up on tapered sleeve inclined-plane, make lock sheet groups tightly bite reinforcing bar by teeth groove; Between tapered sleeve and locking plate, realize and fixing by inclined-plane self-lock mechanism simultaneously, thereby complete the connection to reinforcing bar, simple in structure, easy to operate, be connected firmly.
Described lock sheet groups inner surface is provided with a boss.The position of the end that this design has guaranteed two reinforcing bars to be connected in lock sheet groups.
Described boss is arranged on the centre position of lock sheet groups inner surface.
It is described for the erecting tools of tapered sleeve locking type steel bar connector is installed, it comprises pressure head, screw mandrel, guide rail, worm gear and worm screw, described pressure head coordinates with guide rail, can do back and forth movement along guide rail, on pressure head, be provided with screw thread near guide rail one end, on two pressure heads, hand of spiral is contrary, and with screw mandrel mix proportion feed screw nut pair, described screw mandrel two ends are respectively positive and negative trapezoidal thread, screw mandrel one end is fixedly connected with worm gear, worm gear and worm screw mix proportion worm couple.Drive the rotation of worm gear and screw mandrel by rotary worm, then by the gearing of feed screw nut pair, make pressure head produce axial compression campaign and mutually close, tapered sleeve end is applied to extruding force push, thereby realize the object of hypotelorism between two tapered sleeves.Simple in structure, easy to operate, alleviate operator's the amount of labour.
The other end of described pressure head designs for opening, and opening bore is greater than bar diameter to be connected, is less than tapered sleeve end diameter.Opening design makes erecting tools very easy to use, is conducive to taking off of erecting tools after erecting tools engaging reinforcing bar and installation.
Described worm screw one end is provided with square toes.Can coordinate with manual, pneumatic, electric wrench.
Tapered sleeve locking type steel bar connector and erecting tools thereof that the utility model provides, its beneficial effect is, utilize inclined-plane self-lock mechanism to realize sting the fixing tight and tapered sleeve and lock sheet groups between of lock sheet groups to reinforcing bar, can realize the firm connection of reinforcing bar without other component, simple in structure, easy to operate, greatly alleviate operator's the amount of labour, improve production efficiency, and be connected firmly, non-loosening, stretching resistance experiment shows, adopts tensile strength after this joint connects considerably beyond welded construction.
