Abstract
The utility model discloses a connecting joint for a reinforced bar, which comprises a pair of semicircular connecting clamping sleeves, a pair of reinforced bar end heads with connecting threads which are processed in a rolling or turning way, and a pair of ring hoops, wherein the inner surfaces of the connecting clamping sleeves are provided with threads corresponding to the threads which are processed at the surface of a reinforced bar; the two ring hoops are arranged at the outer sides of the clamping sleeves. The diameter of the middle part of the outer side of each connecting clamping sleeve is larger than the diameters of both ends, the dimension of the nominal diameter of the thread of the inner side of each connecting clamping sleeve is equal to or slightly smaller than the dimension of the nominal diameter of the thread of the outer side of each end part of the reinforced bar and the inner diameter of each ring hoop is slightly larger than the outer diameters of both ends of each connecting clamping sleeve. Because of the outer diameter difference of both ends and the middle part of each connecting clamping sleeve, when the utility model is used for connecting, the ring hoops move to the middle parts and the connecting clamping sleeves and the threads of the end parts of the reinforced bar are tightly engaged to realize the fastening and the connection. The utility model has the advantages that the fit clearances of the threads of the joint are small, the strength exceeds parent metals of the reinforced bar, the assembly is convenient and quick at site, the test is visual, the performance is reliable and the connecting joint is superior to the existing joint of a straight thread of a reinforced bar.
Description
Technical field
The utility model relates to a kind of reinforcing bar fast connecting joint in the construction work.
Background technology
In the modern architecture, reinforcing bar connects speed of application and joint quality has very big influence to programming and workmanship, therefore is regarded as a key link of structure design and construction always.The connecting method for reinforcing bars that adopts in the concrete building structures mainly contains colligation, welding both at home and abroad, and mechanical connection, and at present, the taper thread in the mechanical connection method connects, the sleeve extruding connects, jumping-up is threaded, roll extrusion straight thread connection etc. used more general.But these methods all exist deficiency: taper thread connects, and the intensity of joint does not reach parent material of reinforcement rebar intensity, and the application in structure is restricted; The sleeve extruding connects, and the sleeve steel using amount is big, and cost is higher, and equipment is heavy when station is constructed, and connection speed is slower; Jumping-up, roll extrusion straight thread connect, a screw thread steel silk machining period is longer, and the number of turns of rotational sleeve is also more during connection, and the winding operation in the intensive reinforcing bar is pretty troublesome, when screw shell and screw thread steel fit clearance were big sometimes, phenomenon can appear pulling in joint straight draw test.Once the someone had proposed a kind of " Ribbed Bar kink jointing " (Chinese patent ZL97215872.3), its joint connection speed is fast, but need the cross rib of reinforcing bar appearance and the helicla flute in its adapter sleeve well to coincide and to use, and concerning reinforcing bar, the cross rib of most of reinforcing bar appearances of determining not is to design for connecting reinforcement, the angle of the cross rib of the reinforcing bar of The field, shape, size difference is very big, the manufacturer of adapter sleeve can't corresponding cross rib difference big reinforcing bar like this, design one by one, production has the spiral fluted adapter sleeve that accurately cooperates with the reinforcing bar cross rib, so this joint can't actually be applied.
Summary of the invention
The purpose of this utility model just provides a kind of new reinforcing steel bar jointing, solves construction inconvenience and inefficient problem that prior art exists.Satisfy architectural design, unit in charge of construction better to reinforcing bar connection speed and performance demands.
The technical solution of the utility model: comprise a pair of end reinforced, a pair of semicircle chuck and two hoops of connecting that have connecting thread, a pair of connection chuck is to being buckled in outside two end reinforced connecting threads, two hoops are enclosed within and connect outside the chuck, be provided with and the corresponding screw thread of end reinforced connecting thread in described connection chuck inboard, and mesh together with end reinforced connecting thread; The middle part diameter in the outside of described connection chuck is greater than the diameter at two ends, the internal diameter of at least one end of endoporus of described hoop is greater than the external diameter that connects the chuck two ends, two hoops are when the joint middle part advances, two connection chucks are drawn close, be close to reinforcing bar, and the screw thread thread on the connection chuck is compressed into the thread of steel bar joint screw, reaches tight engagement.
The connecting thread of described steel bar end is made with the equicohesive screw thread cold working of reinforcing bar method with existing, send out as stripping rib rolling behind turning method or the steel bar thick behind direct rolling method, stripping rib rolling method, the steel bar thick etc., screw thread is a straight thread, tooth form is preferably triangle, and thread pitch is in 1.5mm～6.0mm scope.
The pitch of described connection chuck inside thread is identical with the pitch of end reinforced connecting thread, and the nominal diameter of screw thread is equal to or slightly less than the nominal diameter of end reinforced connecting thread.
Advantage of the present utility model: because the external diameter at the two ends of connection chuck of the present utility model and middle part is poor, can be fastening to the mobile realization at middle part when connecting by hoop, connect interior screw thread of chuck and end reinforced connecting thread tight engagement, the Screw Thread Fit Clearance of adapter sleeve and reinforcing bar is at utmost reduced, switching performance and comfort level are better than the existing straight thread connector that is rotatably connected, the narrow positions of the inconvenient turning tool that reinforcing bar is intensive at the construction field (site) particularly, perhaps the invar hypertrophy of tendon and muscle weighs and the position of inconvenience butt joint, and the utility model is more more convenient than the joint winding of existing straight-thread connection method, fast.In addition, the volume of joint is little, bonding strength is high, check is directly perceived, dependable performance, applied widely, no matter be plain bar, or Ribbed Bar, as long as can process screw thread, can both finish connection apace with this structure, therefore be the outstanding new reinforcing steel bar mechanical connecting structure of a kind of advantage.
Below in conjunction with accompanying drawing syndeton of the present utility model is described further.
Description of drawings
Fig. 1 is the overall syndeton vertical section schematic diagram of the utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1;
The specific embodiment
Referring to Fig. 1 and Fig. 2, reinforcing bar jointing of the present utility model comprises end reinforced 1, a pair of semicircle chuck 3 and two hoops 2 of connecting of butt joint.Be equipped with the connecting thread 4 that coincide mutually in described end reinforced 1 the outside and the inboard that is connected chuck 3,3 pairs of a pair of connection chucks are buckled in outside a pair of end reinforced 1, and their screw thread is meshing with each other together.Two hoops 2 are enclosed within the outside at the close two ends that connect chuck 3.The middle part diameter in the outside of described connection chuck 3 is greater than the diameter at two ends, the screw thread 4 nominal diameter sizes that connect chuck 3 inboards are equal to or slightly less than the nominal diameter size of the screw thread in end reinforced 1 outside, the internal diameter of hoop 2 is slightly larger than the external diameter that connects chuck 3 two ends, two hoops 2 are when the joint middle part advances, make connection chuck 3 draw close and be close to, promptly finish connection with reinforcing bar 1.Screw thread 4 is a straight thread, and the tooth form of screw thread 4 is preferably triangle, and the pitch of screw thread is in 1.5mm～6.0mm scope.
