Abstract
The utility model discloses an extrusion taper sleeve locking-type reinforcement joint. The extrusion taper sleeve locking-type reinforcement joint comprises a double-screw bolt, externally sleeved nuts, taper sleeves and locking plates, wherein the externally sleeved nuts are a pair; the pair of externally sleeved nuts are installed on the double-screw bolt back to back; each externally sleeved nut is internally provided with a taper sleeve, and the end surface of each taper sleeve is exposed to the outside of the end surface of each externally sleeved nut; the taper sleeves are internally provided with the locking plates. The pair of externally sleeved nuts are installed, and the externally sleeved nuts are connected with the double-screw bolt in a screwing manner, so that the taper sleeves inside the externally sleeved nuts press the locking plates, and the locking plates and reinforcing steel bars are fastened so as to connect reinforcing steel bars; the end surfaces of the taper sleeves are exposed to the outside of the end surfaces of the externally sleeved nuts, and an extrusion device can be adopted for extruding the taper sleeves, so that the torque is reduced, the extrusion taper sleeve locking-type reinforcement joint is convenient to install, saves labor, is high in production efficiency, and is reliable in connection.
Description
Technical field
The utility model belongs to reinforcing bar locking and connecting device technical field, is specifically related to a kind of crush cones lock set compact form joint of connecting reinforcement.
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.
Summary of the invention
The above-mentioned technical problem existing in order to overcome prior art field, the purpose of this utility model is, the bar splice of a kind of crush cones lock set compact form is provided, easy for installation, efficient, connects reliable.
The crush cones lock set compact form bar splice that the utility model provides, it comprises double-screw bolt, cap nut, tapered sleeve and locking plate, described cap nut is provided with a pair of, a pair of cap nut is back-to-back to be arranged on double-screw bolt, in described each cap nut, be all set with tapered sleeve, and the end face of tapered sleeve exposes in the outside of overcoat nut end face, in described tapered sleeve, locking plate is installed; Described double-screw bolt is two-way double-screw bolt, and a pair of cap nut connects respectively the two ends screw thread of two-way double-screw bolt; The two ends of described locking plate external surface are frustum, and the two ends of described tapered sleeve intracavity section are also frustum, and locking plate cooperation is arranged in tapered sleeve.
The crush cones lock set compact form bar splice that the utility model provides, its beneficial effect is, a pair of cap nut is set, adopt cap nut to screw and be connected with double-screw bolt, thereby make the tapered sleeve of cap nut inside compress locking plate, locking plate and reinforcing bar are fastenedly connected, realize the connection of reinforcing bar; The end face of tapered sleeve exposes in the outside of overcoat nut end face, can adopt pressurizing unit, and tapered sleeve is pushed, and has reduced moment of torsion, makes easy for installation laborsavingly, and production efficiency is high, connects reliable.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of crush cones lock set compact form bar splice;
Fig. 2 is the mounting structure schematic diagram of crush cones lock set compact form bar splice connecting reinforcement.
In figure, mark:
1. cap nut; 2. tapered sleeve; 3. locking plate; 4. double-screw bolt; 5. be connected reinforcing bar; 6. pressurizing unit.
The specific embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the crush cones lock set compact form bar splice that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the crush cones lock set compact form bar splice of the present embodiment, it comprises double-screw bolt 4, cap nut 1, tapered sleeve 2 and locking plate 3, described cap nut is provided with a pair of, a pair of cap nut is back-to-back to be arranged on double-screw bolt 4, in described each cap nut, be all set with tapered sleeve 2, and the end face of tapered sleeve 2 exposes in the outside of cap nut 1 end face, in described tapered sleeve 2, locking plate 3 is installed; Described double-screw bolt 4 is two-way double-screw bolt, and a pair of cap nut 1 connects respectively the two ends screw thread of two-way double-screw bolt; The two ends of described locking plate 3 external surfaces are frustum, and the two ends of described tapered sleeve 2 intracavity sections are also frustum, and locking plate 3 cooperations are arranged in tapered sleeve 2.
Crush cones lock set compact form bar splice connecting reinforcement, at the two ends of crush cones lock set compact form bar splice, is sleeved on by locking plate, tapered sleeve, cap nut the end that is connected reinforcing bar 5 respectively successively, then a pair of cap nut is screwed, is tightened with double-screw bolt simultaneously; Adopt pressurizing unit 6 to be enclosed within the bar splice of crush cones lock set compact form, behind location, the end face of tapered sleeve protrusion cap nut part is applied to extruding force and push, make two ends tapered sleeve Distance Shortened, locking plate tightens up bites reinforcing bar, between cap nut and tapered sleeve, occurs gap; Again screw cap nut and double-screw bolt, eliminate the gap between cap nut and tapered sleeve; Repeat extruding, screw, until tapered sleeve, locking plate are fixed.
Claims (3)
