Abstract
The utility model relates to a combined screw rod lap joint buckle, which comprises a locking belt, lock nuts used for locking both ends of the locking belt, and fixed cores arranged in the lock nuts, wherein external threads in threaded connection with the lock nuts and internal threads in threaded connection with the fixed cores are arranged on both ends of the locking belt, and the fixed cores are in threaded connection with the lock nuts at contact positions. Through the structure, the combined screw rod lap joint buckle has a certain tensile resistance and pressure resistance; fastening force can be predetermined, and the combined screw rod lap joint buckle has the advantages of good fastening performance, strong bearing capacity, convenience for operation, pressure resistance and tensile resistance.
Description
Technical field
The utility model relates to a kind of rope band connected fastener, what be specifically related to is that a kind of rope band is with making up the screw mandrel lap buckle.
Background technology
What present two rope bands adopted as the overlap joint of steel cable is the locking lap buckle, it comprises U-shaped locking strip and fixed cover, and this fixed form is by the two ends of U-shaped locking strip, nut to be installed to arrive the locking purpose, but this mode is fixing unstable, and, the two ends of U-shaped locking strip each with a nut ease of connection in the situation that the rope band pulling force is large tries to shirk responsibility, therefore easily cause fixing unstable, the problem of complicated operation.
Especially existing building reinforcement construction technique, the overlap joint of reinforcing bar is generally to carry out manual colligation according to national regulation, or welding, and manual colligation is complicated, and tightness is poor, and the dynamics of bearing is inadequate, and causing has potential safety hazard.And existing welding manner does not generally allow to use in the construction of building site, and is easily disconnected to steel wire welded in the middle of the existence welding, causes potential safety hazard large, and bone does not allow to use.Then realize the overlap joint of two reinforcing bars with grip of concrete, therefore when there is no casting concrete, compression effort and tensile stress can not be born by lap-joint, and this can not meet the requirement of Novel splicing structure.
The utility model content
For the deficiency that exists on prior art, the utility model purpose is to be to provide a kind of punching press splicing screw thread (CYPJ screw thread), namely make up the screw mandrel lap buckle, have advantages of that bearing capacity is strong, easy to operate, the resistance to compression tension, can meet the stable stress of needs in splicing.
To achieve these goals, the utility model is to realize by the following technical solutions:
Combination screw mandrel lap buckle, it comprises locking strip, is used for the jam nut at locking locking strip two ends and is arranged on the interior fixed core of jam nut, described locking strip two ends are provided with the outside thread that is threaded with lock nut and the negative thread that is threaded with fixed core, and described fixed core and jam nut contact position are threaded connection.
Above-mentioned combination screw mandrel lap buckle, wherein, described locking strip takes the shape of the letter U, and its end cross-sectional is in the arc-shaped.
Above-mentioned combination screw mandrel lap buckle, wherein, described fixed core is provided with the lock slots for fixedly locked strap end portion, be provided with the groove screw thread suitable with the locking strip outside thread in described lock slots, the described lock slots degree of depth equates with the thickness of locking strip end, and described locking strip two ends are inserted in lock slots and formed a core screw rod.
Above-mentioned combination screw mandrel lap buckle, wherein, described jam nut is hexagonal nut.
The utility model CYPJ screw thread (punching press splicing screw thread) namely makes up the screw mandrel lap buckle can provide certain bearing capacity to the overlap joint reinforcing bar, can meet the stable stress of needs in splicing.It utilizes U-shaped steel plate strip, and the screw thread that strikes out arc is arranged in both side ends, utilizes in addition the punching press screw thread of a fixed core and U-shaped locking strip, is spliced into the core screw rod, separately joins a jam nut.The use procedure of compound type bayonet socket is that the overlap joint reinforcing bar is placed among U-shaped locking strip, be spliced into the core screw rod with fixed core, then screwing with jam nut, in the process that screws inwards of jam nut, U-shape lock surely is with and is compressed two overlap joint reinforcing bars, under positive pressure, will provide certain tension and pressure resistance; Its fastening force can be preset, and fastening performance is good, and bearing capacity is strong, easy to operate, the advantage of resistance to compression tension.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand,, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, a kind of punching press splicing of the utility model screw thread (CYPJ screw thread), namely make up the screw mandrel lap buckle, the overlap joint that is mainly used in architectural two reinforcing bars 40 is fixed, it comprises locking strip 10, is used for the jam nut 20 at locking locking strip two ends and is arranged on the interior fixed core 30 of jam nut 20, the U-shaped steel band that this locking strip 10 adopts, its end cross-sectional is in the arc-shaped.All be processed with the outside thread that is threaded with lock nut 20 and the negative thread that is threaded with fixed core 30 at locking strip 10 two ends, internal and external screw thread forms curved screw thread 11.
In the present embodiment, this fixed core 30 is threaded connection with jam nut 20 contact positions, fixed core 30 is provided with for fixedly locked lock slots with 10 ends 31, be provided with the groove screw thread suitable with the locking strip outside thread in lock slots 31, the degree of depth of lock slots 31 equates with the thickness of locking strip end, and with the locking strip end, match, jam nut 20 is hexagonal nut, the outside thread of the outside thread of its negative thread and fixed core 30 and locking strip 10 is suitable, and the core screw rod that forms whole connection jam nut negative thread in lock slots is inserted at locking strip 10 two ends.The outside thread of the lock slots of the present embodiment is provided with long enough, can guarantee that nut can lock the purpose of rope band, and the rope band of the present embodiment is reinforcing bar 40.
the present embodiment is using, at first two reinforcing bars 40 are placed in the U-shaped steel band up and down, then fixed core 30 is placed between the U-shaped steel band two ends of reinforcing bar 40 tops, U-shaped steel band two ends are placed in lock slots 31, its negative thread matches with the groove screw thread and forms the core screw rod, then jam nut 20 is enclosed within on the core screw rod, by spanner rotational lock nut 20, jam nut is screwed, in the process that screws inwards of jam nut, nut moves down and compresses reinforcing bar 40, up and down two reinforcing bars 40 tightly are locked together, under positive pressure, certain tension and pressure resistance will be provided, its fastening force can be preset, and fastening performance is good, and bearing capacity is strong, easy to operate, the advantage of resistance to compression tension.
Above demonstration and described groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
