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 belt and fixed cover, and this fixed form is by the two ends of U-shaped locking belt 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 belt 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 cross according to national regulation to fix, but tie up not tight, double swerve, poor stability, 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 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 the cross-lap joint button, it is fixing to be mainly used in roof grid structure cross splicing for building, have that bearing capacity is strong, easy to operate, the advantage of resistance to compression tension, can not use main equipment controlled tensile stress is provided for the overlap joint reinforcing bar.
To achieve these goals, the present invention realizes by the following technical solutions:
The cross-lap joint button, it is characterized in that, it comprises locking belt, locking nut and is arranged on the interior fixed core of locking nut, described locking belt comprises two U-shaped bands that are right-angled intersection, each U-shaped band two ends is provided with the screw thread that is threaded with lock nut and fixed core, described fixed core is provided with the screw thread groove for the engaging screw thread, and described screw thread is inserted and constituted a core screw rod that is threaded with lock nut in the screw thread groove.
Above-mentioned cross-lap joint button, wherein, right-angled intersection place of two described U-shaped bands is fixedly connected, and described locking belt integral type casting.
Above-mentioned cross-lap joint button, wherein, described screw thread is the circular arc screw thread, described circular arc screw thread is installed in and constitutes described core screw rod in the screw thread groove.
Above-mentioned cross-lap joint button, wherein, described screw thread is provided with screw thread external screw thread and screw thread internal thread, is provided with the groove screw thread suitable with the screw thread internal thread in the described screw thread groove, and the described lock slots degree of depth equates with the locking belt end portion thickness.
Above-mentioned cross-lap joint button wherein, is provided with the core screw thread with the locking nut contact position on the described fixed core, and described core screw thread and screw thread external screw thread constitute the suitable threaded portion of locking nut internal thread.
Above-mentioned cross-lap joint button, wherein, described locking nut is hex nut.
Cross-lap joint button of the present invention provides certain bearing capacity can for the overlap joint reinforcing bar, can satisfy the stable stress of needs in the splicing, it utilizes two U-shaped bands to be cast into one and four side ends have the screw thread that strikes out arc, utilize a fixed core and screw thread in addition, be spliced into the core screw rod, the overlap joint reinforcing bar is cross and places among the U-shaped button, screw being enclosed within the core screw rod with locking nut then, in the process that screws inwards of locking nut, two U-shaped steel bands compress two and are font overlap joint reinforcing bar, under positive pressure, will provide certain tension and anti-pressure ability; Its fastening force can be preset, and is applicable to that roof grid structure cross splicing for building is fixing, and it is good to have fastening performance, and bearing capacity is strong, easy to operate, the advantage of resistance to compression tension, can not use main equipment controlled tensile stress is provided can for the overlap joint reinforcing bar.
