Detailed description of the invention
The utility model provides a kind of bar connecting device, as shown in Figure 1, its Structure composing comprises a master collet 10, Fig. 2 shows the sectional structure of master collet, this master collet 10 entirety is the long tubular that mid diameter is large, reduce gradually to both ends diameter, the two ends of master collet 10 are respectively equipped with from internal thread hole that is open-ended, that extend to middle part, are respectively the first internal thread hole 11 and the second internal thread hole 12, two internal thread holes are coaxially arranged; Wherein, the internal thread of the first internal thread hole 11 and the end reinforced external screw thread formed through screw thread process match; In second internal thread hole 12, the internal diameter size of internal thread can penetrate for end reinforced just, and on the sidewall of the second internal thread hole 12, relative both sides have and cut two straight joints 13 to the second internal thread hole vertically from opening part, make the sidewall of the second internal thread be divided into two parts by two straight joints.One section of lateral wall that master collet 10 is positioned at the second position, internal thread hole openend is provided with external screw thread along its lateral wall tapering, securing member 20 is also socketed with in this section of external screw thread position of master collet, Fig. 3 shows the sectional structure of securing member, as shown in Figure 3, this securing member 20 comprises the annular element 21 of a circulus, the lateral wall of annular element 21 is polygon, such as hexagon, octagon etc. (the annular element lateral wall shown in Fig. 3 is octagon), the instruments such as spanner easy to use clamp, the inside wall of annular element 21 have be positioned at the second position, internal thread hole openend with master collet lateral wall on the internal thread that matches of the external screw thread at diameter minimum position place, securing member 20 is connected on the external screw thread of the second position, internal thread hole openend of master collet 10 by the internal thread rotation on annular element 21 inside wall.
Bar connecting device of the present utility model for connect in prefabricated units two cannot rotate reinforcing bar time, its using method is as follows: first, by the external screw thread needing the end of the first side reinforcing bar connected to be formed by screw thread process, then use bar connecting device of the present utility model to be screwed on the end reinforced external screw thread in the first side by the first internal thread hole of its master collet, be fixed tightly on the first side reinforcing bar until master collet is spun, after this, on the external screw thread that diameter is minimum on the lateral wall that the second position, internal thread hole openend of bar connecting device master collet is socketed with securing member and securing member is only screwed in the second position, internal thread hole openend of master collet, now on master collet, the second internal thread hole is not received extruding by two parts sidewall that two straight joints are separated, be in relaxed state, at this moment in the second internal thread hole, the internal diameter size of internal thread can penetrate for end reinforced just, therefore will the end of the second side reinforcing bar connected be needed through the second internal thread hole penetrated after the annular element of securing member to master collet, finally, the lateral wall using the tool holdings such as spanner to live annular element rotates securing member, make to move to direction in the middle part of master collet under the cooperation of securing member between external screw thread on the second position, internal thread hole openend lateral wall of internal thread and the master collet of annular element, gradually the second position, internal thread hole openend is positioned to master collet in its moving process and forms inside extruding force, and then impel the second internal thread hole mutually to be drawn close by two parts sidewall that two straight joints are separated, to penetrating the second side end reinforced formation extruding occlusion in the second internal thread hole, make the master collet of bar connecting device and the second side is end reinforced is fixed together, realize the connection of the first side reinforcing bar and the second side reinforcing bar.Therefrom can see, bar connecting device of the present utility model, its master collet entirety is the long tubular that mid diameter is large, reduce gradually to both ends diameter, can ensure that two reinforcing bars after connecting have enough tensile strength at master collet connecting portion preferably, first internal thread hole of master collet mainly plays and to form externally threaded end with the first side steel bar meter and mutually to spin the effect agreed with, and the internal thread in the second screwed hole of master collet is not used to screw thread spins, at securing member by rotating in the process of direction movement in the middle part of master collet under institute's externally applied forces effect, the second side end reinforced formation extruding occlusion that two parts sidewall of master collet second internal thread hole is stressed and mutually draw close penetrating wherein, internal thread in second internal thread hole just can to the enough mechanical snap power of the second end reinforced formation in side and frictional resistance, its bonding strength is even higher than general mechanical connection, master collet is made to become to be integrated with the second side bar connecting securely, thus the reliability that two reinforcing bars are connected can be ensured well.
When specifically practicing, in the utility model bar connecting device, the annular element of securing member can directly adopt nut to realize.And as further improvement project, as shown in Figure 4, in the securing member 20 of the utility model bar connecting device, the lateral wall of its annular element 21 can also be fixedly connected with a lever 22, this lever 22 entirety is in strip, and its length direction is arranged towards the axis direction of annular element 21.Like this when carrying out connection, then directly can carry out turn Fastener by lever, and without the need to by the extra instrument such as spanner, connection operation is more convenient.
In sum, can see, bar connecting device bonding strength of the present utility model is high, and installation is convenient, and install and use the restriction not being subject to the factors such as grouting material solidifies, the connection to reinforcing bar can be realized fast, if when generation bar connecting installs the reinforcing bar makeing mistakes or need releasing to connect in addition, its disassembling section is the inverse process of fitting operation, dismantle also very convenient, and bar connecting device can be reused after dismounting, be conducive to saving material cost, good economy performance.As can be seen here, bar connecting device of the present utility model provides a kind of new connection equipment and Joining Technology for the bar connecting in prefabricated units, solves well between the reinforcing bar that cannot rotate in the prefabricated units of prior art and lacks simple, to connect equipment efficiently technical problem.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
