Abstract
The invention relates to a combination screw rod overlapping thread comprising a locking belt, a locking nut for locking two ends of the locking belt, and a fixing core arranged in the locking nut. The two ends of the locking belt are each provided with an external screw thread connected with a screw thread of the locking nut and an internal screw thread connected with a screw thread of the fixing core, and contacting positions of the fixing core and the locking nut are connected by the screw threads. The combination screw rod overlapping thread has a certain anti-tension capability and a certain anti-compression capability with the use of the structure; and the combination screw rod overlapping thread has a fastening force which can be preset, and has the advantages of excellent fastening performance, strong bearing capability, convenient operation, anti-compression and anti-tension performance.
Description
?
Technical field
What the present invention relates to is a kind of rope band connected fastener, and 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, each tries to shirk responsibility the two ends of U-shaped locking strip under the big situation of rope band pulling force with a nut ease of connection, therefore easily causes fixing instability, the problem of complicated operation.
Especially existing building reinforcement construction technology, the overlap joint of reinforcing bar generally is to carry out manual colligation according to national regulation, or welding, manual colligation complexity, tightness is poor, and the dynamics of bearing is not enough, and causing has potential safety hazard.And existing welding manner does not generally allow to use in the construction of building site, and is disconnected to steel wire welded easily in the middle of the existence welding, causes potential safety hazard big, and bone does not allow to use.Realize the overlap joint of two reinforcing bars then with grip of concrete, therefore when not having concreting, compressive stress and tensile stress can not be born by lap-joint, and this does not satisfy the requirement of novel splicing construction.
Summary of the invention
At the deficiency that exists on the prior art, the present invention seeks to be to provide a kind of punching press splicing screw thread (CYPJ screw thread), namely make up the screw mandrel lap buckle, have that bearing capacity is strong, easy to operate, the advantage of resistance to compression tension, can satisfy the stable stress of needs in the splicing.
To achieve these goals, the present invention realizes by the following technical solutions:
Combination screw mandrel lap buckle, it comprises locking strip, is used for the locking nut at locking locking strip two ends and is arranged on the interior fixed core of locking nut, described locking strip two ends are provided with the external screw thread that is threaded with lock nut and the internal thread that is threaded with fixed core, and described fixed core and locking nut contact position are by being threaded.
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, in described lock slots, be provided with the groove screw thread suitable with the locking strip external screw thread, the described lock slots degree of depth equates that with the locking strip end portion thickness described locking strip two ends are inserted and constituted a core screw rod in the lock slots.
Above-mentioned combination screw mandrel lap buckle, wherein, described locking nut is hex nut.
CYPJ screw thread of the present invention (punching press splicing screw thread) namely makes up the screw mandrel lap buckle and certain bearing capacity is provided can for the overlap joint reinforcing bar, can satisfy the stable stress of needs in the splicing.It utilizes U-shaped steel plate band, in both side ends the screw thread that strikes out arc is arranged, and utilizes the punching press screw thread of a fixed core and U-shaped locking strip in addition, is spliced into the core screw rod, and other joins a locking nut.The use of combined type bayonet socket is that the overlap joint reinforcing bar is placed among the U-shaped locking strip, be spliced into the core screw rod with fixed core, screwing with locking nut then, in the process that screws inwards of locking nut, U-shaped locking strip compresses two overlap joint reinforcing bars, under positive pressure, will provide certain tension and anti-pressure ability; 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 present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Referring to Fig. 1 and Fig. 2, a kind of punching press splicing of the present invention 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, be used for the locking nut 20 at locking locking strip two ends and be arranged on fixed core 30 in the locking 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 external screw thread that is threaded with lock nut 20 and the internal thread that is threaded with fixed core 30 at locking strip 10 two ends, internal and external screw thread constitutes curved screw thread 11.
In the present embodiment, this fixed core 30 and locking nut 20 contact positions are by being threaded, fixed core 30 is provided with for fixedly locked lock slots 31 with 10 ends, in lock slots 31, be provided with the groove screw thread suitable with the locking strip external screw thread, the degree of depth of lock slots 31 equates with the locking strip end portion thickness, and match with the locking strip end, locking nut 20 is hex nut, the external screw thread of the external screw thread of its internal thread and fixed core 30 and locking strip 10 is suitable, and the core screw rod that constitutes whole connection locking nut internal thread in the lock slots is inserted at locking strip 10 two ends.The external screw thread of the lock slots of present embodiment is provided with long enough, can guarantee that nut can lock the purpose of rope band, and the rope band of present embodiment is reinforcing bar 40.
Present embodiment is using, at first two reinforcing bars 40 are placed on up and down in the U-shaped steel band, 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 the lock slots 31, its internal thread matches with the groove screw thread and constitutes the core screw rod, then locking nut 20 is enclosed within on the core screw rod, by spanner rotational lock nut 20, locking nut is screwed, in the process that screws inwards of locking nut, nut moves down and compresses reinforcing bar 40, and making up and down, two reinforcing bars 40 tightly are locked together, under positive pressure, will provide certain tension and anti-pressure ability; 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.
