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, because developing rapidly of domestic economy, living standards of the people improve day by day, 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, 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.Especially in the time two reinforcing bars need being linked together at a certain distance or connect two fixing reinforcing bars, the shortcoming of above-mentioned traditional reinforcing bar connected mode just seems particularly evident.Though people have proposed multiple novel reinforcing bar connector, these connectors all can not fine solution with two reinforcing bars problem of linking together of spacing on demand.
The purpose of this utility model is to provide a kind of reinforcing bar connector, and this reinforcing bar connector can link together two reinforcing bars by required spacing, and connects quick and convenient.
Above-mentioned purpose of the present utility model is to realize by the connector of following structure, this connector comprises metal sleeve, this sleeve comprises first end, this end is 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, this end has the externally threaded reinforcing bar of same specification to link to each other with cutting, metal sleeve also comprises and the first end opposite second end, this end is provided with internal thread, above-mentioned connector also comprises flexible metallic sheath, this metallic sheath comprises first end, this end appearance is provided with the external screw thread identical with the internal thread specification of above-mentioned metal sleeve the second end, be somebody's turn to do the second end that flexible metallic sheath is screwed in metal sleeve by this external screw thread, and this metal sleeve moves axially along metal sleeve relatively, above-mentioned flexible metallic sheath also comprises and its first end opposite second end, this the second end is 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, this end has the externally threaded reinforcing bar of same specification to be connected with cutting, between the second end of the second end of above-mentioned flexible metallic sheath and metal sleeve, be provided with the locking metallic sheath, this locking metallic sheath is provided with and the identical internal thread of metallic sheath first end external screw thread specification that stretches, should lock the metallic sheath rotation set on the external screw thread of the first end of flexible metallic sheath by this internal thread, above-mentioned in addition locking metallic sheath also is provided with and the set identical external screw thread of internal thread specification in the metal sleeve the second end outside near a side appearance of metal sleeve the second end, and the opposite side of locking metallic sheath is provided with the boss that radially outwards protrudes, can be screwed into the second end of metal sleeve near a side of metal sleeve by the above-mentioned locking metallic sheath of this external screw thread, and the boss of metallic sheath opposite side is pressed on the side of metal sleeve the second end, thereby realizes the locking of flexible metallic sheath.
Another characteristics of the present utility model are, the cone angle in above-mentioned conical internal thread hole is 3 °, and the pitch of conical internal thread is 2.5mm.
Advantage of the present utility model is and reinforcing bar can be coupled together to adapt to the occasion of multiple construction by the spacing that is fit to.
Another advantage of the present utility model is to connect fast, saves the energy, and is easy to operate.
An advantage more of the present utility model is, owing to adopted specific cone angle and taper thread spacing, thus improved the bonding strength of reinforcing bar greatly.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the floor map of the utility model connector.
As shown in Figure 1, connector of the present utility model comprises metal sleeve (1), this sleeve comprises end (2), this end is provided with conical internal thread (3), there is the externally threaded reinforcing bar (4) of same specification to link to each other by this conical internal thread end (2) with cutting, metal sleeve (1) also comprises end (5), this end (5) is relative with end (2), this end (5) is inner for having the cylindrical bore of internal thread (6), by this internal thread (6), end (5) has the externally threaded flexible metallic sheath (7) of same specification to spin mutually with cutting, should stretch metallic sheath (7) by rotation moving axially along metal sleeve (1), thereby realize the flexible of whole connector, flexible metallic sheath outer end (8) is provided with conical internal thread (9), by this conical internal thread, this outer end (8) has the externally threaded reinforcing bar (10) of same specification to be connected with cutting, between the outer end (8) of the end (5) of metal sleeve (1) and flexible metallic sheath, be provided with locking metallic sheath (11), this locking metallic sheath (11) is provided with internal thread, this internal thread is identical with the external screw thread specification of flexible metallic sheath (7), thereby should locking metallic sheath rotatably encapsulation in the outside of flexible metallic sheath, the side appearance cutting that locks the end (5) of the close metal sleeve of metallic sheath in addition has external screw thread, this external screw thread is identical with the internal thread specification in end (5) outside, thereby a side of the close metal sleeve end (5) of this locking metallic sheath (11) can screw in this end (5) to realize the locking of flexible metallic sheath (7).
Can be earlier during construction the end (2) of metal sleeve (1) be linked to each other with the end of reinforcing bar (4), afterwards, to lock the outside that metallic sheath (11) is enclosed within flexible metallic sheath (7), the flexible metallic sheath (7) that will have locking metallic sheath (11) again is screwed in the end (5) of metal sleeve (1), reinforcing bar (10) is screwed in conical internal thread (9) hole of flexible metallic sheath (7), if at this moment the end of reinforcing bar (10) is not screwed into fully, the metallic sheath that stretches (7) outwards can be screwed out suitable distance, so that the end of reinforcing bar (10) all is screwed in the conical internal thread hole of flexible metallic sheath, at last, the spin locking metallic sheath, its end is screwed in the metal sleeve end (5), thereby realizes the locking of flexible metallic sheath (7).
