Abstract

The utility model relates to a connecting device for reinforcing bars, which comprises a metal sleeve barrel, wherein, the sleeve barrel comprises a first end part; tapered inner threads are arranged on the first end part; the sleeve barrel also comprises a second end part; inner threads are arranged on the second end part, so the second end part can be connected with a moving sleeve provided with outer threads of which the specification is similar to the appearance; a fixing sleeve is sheathed in the moving sleeve; tapered inner threads are arranged at the outside of the fixing sleeve. The cone angle of the tapered inner thread in the fixing sleeve and the tapered inner threads in the first end part is 3 DEG, and the thread pitch is 2.5 mm. Tapered inner thread holes are connected with the reinforcing bars which are cut into outer threads with the same specification. Thus, the connection strength is greatly enhanced.

Description

Connecting device for reinforcing bar
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.Especially when needs connect into certain angle with two reinforcing bars, shortcoming in above-mentioned traditional method of attachment seems particularly evident, people have proposed multiple novel reinforcing bar connector for this reason, connect but these connectors are difficult to that also two reinforcing bars are pressed certain angle (non-rectilinear).
The purpose of this utility model is to provide a kind of reinforcing bar connector, and this reinforcing bar connector can couple together reinforcing bar by required suitable angle.
Above-mentioned purpose of the present utility model is to realize by the reinforcing bar connector of following structure, this reinforcing bar 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, the above-mentioned first end that is provided with conical internal thread has the externally threaded reinforcing bar of same specification to be connected with cutting, metal sleeve also comprises and the first end opposite second end, this inner end portion is a cylinder hole, the inner in this hole is provided with the inner face that metal sleeve forms, the outer end opening in this hole, above-mentioned cylinder hole is divided into inside and outside two parts, be level and smooth column face wherein near the hole inner end portion, near outer end of hole partly is the column inner threaded surface, in cylinder hole, be provided with the fixing metal cover, this metallic sheath is made of base portion and anchorage part, this base portion is near the inner, hole, it just inserts in the level and smooth column face in the cylinder hole and is pressed against on the inner face of metal sleeve, anchorage part and pedestal part in this metallic sheath are divided into integral body, this anchorage part is provided with conical internal thread, its formed taper thread hole is little near the diameter of the inboard of metal sleeve, and it is big near the diameter in the metal sleeve outside, the above-mentioned fixing metal cover that is provided with conical internal thread has the externally threaded reinforcing bar of same specification to be connected with cutting, above-mentioned anchorage part appearance is with the live metal cover, this live metal cover outer end is provided with crowning, its inner appearance is provided with the external screw thread identical with the internal thread specification of metal sleeve the second end, is rotatably connected in the inside of this metal sleeve the second end by this live metal cover of this external screw thread.
Another characteristics of the present utility model are that the tapering of the conical internal thread in the anchorage part of conical internal thread in the above-mentioned metal sleeve first end and fixing metal cover is 3 °, and the pitch of internal thread is 2.5mm.
Advantage of the present utility model is and reinforcing bar can be linked together by required angle, connects fast, and is easy to operate, compares with welding method and can save a large amount of energy, compares with the assembling reinforcement method and can save great deal of steel.
Another advantage of the present utility model is, owing to adopted specific cone angle and pitch, can improve bonding strength greatly.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a general plane schematic diagram of the present utility model;
Fig. 2 is the floor map of the live metal cover in the utility model connector;
Fig. 3 is the floor map of the fixing metal cover in the utility model connector;
Fig. 4 is the floor map of the metal sleeve in the utility model.
As shown in Figure 1, reinforcing bar connector of the present utility model comprises metal sleeve (1), it 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 end of this conical internal thread (3) (2) with cutting, above-mentioned metal sleeve (1) also comprises end (5), as shown in Figure 4, this inner end portion is formed with cylinder hole, the inner of cylinder hole is to be formed by the inner face of metal sleeve (6), above-mentioned cylinder hole outer end opening, the inboard of cylinder hole is the level and smooth face of cylinder (7), the cylinder hole outside is column inner threaded surface (8), by this inner threaded surface, above-mentioned end (5) spins mutually with the externally threaded live metal cover (9) that appearance is formed with same specification, as shown in Figure 2, this live metal cover outer end is provided with crowning (10), be set with fixing metal cover (11) in this live metal cover, as shown in Figure 3, fixing metal cover (11) comprise base (12) and with this base all-in-one-piece anchoring body (13), above-mentioned base (11) just inserts in the level and smooth face of cylinder (7), the bottom abutment of base is on inner face (6), anchoring body (13) is provided with conical internal thread (14), has the externally threaded reinforcing bar (15) of same specification to be connected by the above-mentioned anchoring body of this conical internal thread with cutting.When construction, can earlier reinforcing bar be connected with the end (2) of metal sleeve (1), then the fixing metal cover is connected with reinforcing bar (15), the fixing metal cover (11) that will have reinforcing bar (15) afterwards inserts in the cylinder hole on the inner face (6) of bottom abutment in the hole of the base (12) of fixing metal cover (11), at last live metal cover (9) is screwed in the end (5) and makes reinforcing bar and fixing metal cover location, reinforcing bar (4) and (15) angle are on demand linked together.
