The present invention relates to a reinforcing bar connector for connecting a reinforcing bar.

Conventional connector of reinforcing rods is known, such as consisting of two brackets made of sheet metal, or a combination of two tubes. However, in the conventionally known connector, the strength is weak, and it is complicated in the assembly operation and poor in the durability of the connector.

The present invention eliminates the drawbacks of the prior art, and furthermore, its strength is greater than that of the connector, and the connector is easily assembled and disassembled into the reinforcing bar, and the problem is to create a reinforcing bar connector having excellent durability. It was set as.

This task consists of technical means in the scope of the claims, namely two tube bodies and a cheesy sleeve, each having a ring-shaped groove engaging with the ribs of the reinforcing rods to be interconnected, and an axial direction of the cheesy sleeve. It consists of a tube body of two reinforcing bar connecting members, and a retaining sleeve, characterized in that it has a flange for fixing, a pin hole for press-fitting a stopper pin for fixing in the axial direction of the retaining sleeve, The tubes are each two flanges (3) and (4) in which a flange for axial fixation of the crank sleeve and one sleeve (5) pre-fitted into the iron (2) to be interconnected are joined together. Wound and wound from outside to hold the two tube bodies 3 and 4 integrally, wherein one end of the sleeve 5 is the flange 3a of the two tube bodies 3 and 4 ) And (4a). On the other hand, the other end of the sleeve 5 is fixed by the stopper pins 6 and 6 pressed into the pin holes 3c and 4c provided in the two tube bodies 3 and 4. As a result, the sleeve 5 is prevented from moving in the axial direction on the tube bodies 3 and 4. Since the sleeve 5 increases the strength particularly in the central range of the connector, the sleeve 5 can be covered with a reinforcing ring 7 on its outer surface, and the reinforcing ring 7 tightly fitted to the sleeve 5 is welded. It is fixed on the outer surface of the sleeve 5 by the.

6, 7 (a) and 7 (b) show a second embodiment of the reinforcing bar connector, and according to FIG. 6 the integral sleeve 5 and the reinforcing ring of the first embodiment Instead of 7), the sleeve and the reinforcing ring are formed into two pieces. Reinforcing rings 13 and 17 are coupled to one sleeve half 11 and the other half sleeve 15 by welding 14 and 18, respectively. And (15) are fitted over the tubes 3 and 4 shown in FIG. 2, and then tightened by bolts and nuts (not shown). The structures and actions of the tubes 3 and 4 are the same as in the case of the first embodiment shown in FIGS. 1 and 2. According to FIGS. 7A and 7B, 11 and 15 represent one and the other half of the sleeve half, and 11a and 15a show a bracket having a configuration for passing a bolt (not shown). And (13) and (17) represent reinforcement rings, and (14) and (18) represent reinforcement rings 13 on one and the other of the sleeve halves 11 and 15 because of the reinforcement of the sleeve half. ) And (17) are shown as spot welding.

According to the present invention, one sleeve is sewn on the outer surface of the two tube bodies, so that the assembly and disassembly of the connector to the reinforcing bar in the field is easy, and furthermore, the durability and the strength of the reinforcing bar connector are high. Can be obtained.
