Abstract
The utility model relates to a connecting device for reinforcing bar which is provided with a metal sleeve. The end part of the sleeve is provided with conical contour internal threads. The end part provided with internal threads is connected with a metal clip sleeve provided with outer screws of the same standard on the surface, and the inner of the metal clip sleeve also has conical contour internal threads. The metal clip sleeve provided with conical contour internal screw threads is connected with steel bars which are provided with outer screws of the same standard. The advantages of the utility model are that the connection strength can be greatly improved and the phenomenon of steel bars fracturing on the connecting position can be avoided.
Description
The utility model relates to a kind of reinforcing bar connector, and it is used for the connection of building operations reinforcing bar.
At present, owing to developing rapidly of domestic economy, living standards of the people improve day by day, and urban population is intensive, and building land more and more lacks, so highrise building rolls up thereupon.But the inside of high-rise building need be provided with a large amount of reinforcing bars, and to form firm steel work, building is high more, and its difficulty of construction is big more.The basic charge that the reinforcing bar of highrise building sets up accounts for high ratio in whole engineering cost, so people wish that the connection of reinforcing bar is simple and convenient.
At present, general connecting method for reinforcing bars comprises colligation overlap joint and welding in the building operations, and is low through the reinforced steel bar strength of colligation overlap joint, and expends great amount of manpower and material resources, and the electric welding connecting reinforcement engineering time is long, energy consumption is high, and can produce secondary stress to reinforcing bar.People have proposed multiple novel reinforcing bar connector for this reason, but all there is the low shortcoming of bonding strength in these connectors.
The purpose of this utility model is to provide a kind of reinforcing bar connector, and this reinforcing bar connector can improve the bonding strength of reinforcing bar greatly, and it is quick and convenient that reinforcing bar is connected.
Above-mentioned purpose of the present utility model is to finish by the connector of following structure, this connector comprises metal sleeve, two opposed ends of this metal sleeve are provided with conical internal thread, formed taper thread hole is little near the diameter of metal sleeve inboard, and the diameter in the outside of close metal sleeve is big, above-mentioned two ends that are provided with conical internal thread have the externally threaded metal chuck of same specification to be connected with the appearance cutting, be provided with conical internal thread in this metal chuck, formed taper thread hole is little near the diameter of metal sleeve inboard, and big near the diameter in the metal sleeve outside, this metal chuck that is provided with conical internal thread has the externally threaded reinforcing bar of same specification to be connected with the appearance cutting.
Another characteristics of above-mentioned connector are that the cone angle in formed taper thread hole, metal sleeve end is 3 °, and the pitch of screw thread is 2.5mm.
Characteristics again of above-mentioned connector are that the cone angle in the formed taper thread of metal chuck hole is 3 °, and the pitch of screw thread is 2.5mm.
Advantage of the present utility model is that the bonding strength of reinforcing bar can improve greatly, has avoided the often phenomenon of fracture of connecting portion reinforcing bar.
Another advantage of the present utility model is, owing to selected specific cone angle and pitch for use, makes limit tension bonding strength limit 1.45 times of tensile strength for the raw steel tendon exhaustion.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the generalized section of the utility model connector;
Fig. 2 is that the axle side of the utility model connector is decomposed generalized section.
As depicted in figs. 1 and 2, connector of the present utility model comprises metal sleeve (1), this metal sleeve (1) comprises end (2) and (3), above-mentioned end (2) and (3) are provided with conical internal thread (4) and (5), this end (2) and (3) inside are connected with the appearance cutting respectively the external screw thread (6) of same specification and metal chuck (8) and (9) of (7), this metal chuck (8) and (9) inside are respectively equipped with conical internal thread (10) and (11), and this metal chuck (8) that is provided with metal internal thread has the external screw thread (12) of same specification and the reinforcing bar (14) of (13) to be connected with (15) with (9) with cutting.
Claims (3)
1, a kind of reinforcing bar connector, it is characterized in that it comprises metal sleeve, two opposed ends of this metal sleeve are provided with conical internal thread, formed taper thread hole is little near the diameter of metal sleeve inboard, and it is big near the diameter in the metal sleeve outside, above-mentioned two ends that are provided with conical internal thread have the external screw thread metal chuck of same specification to link to each other with the appearance cutting respectively, also be provided with conical internal thread in this metal chuck, formed taper thread hole is little near the metal sleeve inside diameter, and big near the diameter in the metal sleeve outside, this metal chuck that is provided with metal internal thread has the externally threaded reinforcing bar of same specification to be connected with cutting.
2, connector according to claim 1 it is characterized in that the cone angle in formed taper thread hole, above-mentioned metal sleeve end is 3 °, and the pitch of screw thread is 2.5mm.
