Abstract

The utility model relates to a quick strong connector for steel bars, comprising a compression nut, two semi-circular clamping members, and a main connecting body. The clamping members are combined to be a structural member, the outer side of the structural member is provided with an upper and a lower conical surfaces, and the structural member is engaged with the steel bars through threads. When the quick strong connector for steel bars is used, the connected steel bars are inserted into both ends of the cylindrical main connecting body; each steel bar is sheathed with the clamping member; both ends of the main connecting body are tightly screwed through cap nuts; both ends of the main connecting body and a conical surface formed after the cap nut is screwed are used to be matched with the two conical surfaces of the clamping members, and accordingly, two steel bars are firmly connected together. The utility model has fast speed for connecting the steel bars, the steel bars on the connecting position are straight, and the intensity is improved.

Description

Quick-acting strong connector for concrete bar

The utility model relates to a kind of reinforcing bar rapid strong connector.

Connect and reinforcing bar is inserted in the useful steel wire lashing of the existing connecting method for reinforcing bars of construction work, electric welding with a sleeve, with the interconnective method of tapered thread, but adopt the steel wire lashing method, nonconforming because of its connection stress, pass into disuse already, adopt welding, though can improve its junction intensity, but often because of when welding produces high temperature, make the rotten overall construction intensity that influence of steel, and will move during construction, because of the difference of job location and weld equipment, time-consuming; And the employing threaded connection method, because of tapered thread, processing difficulties, and between reinforcing bar and sleeve, be difficult for cooperating, loosening easily, be difficult for ensuring the quality of products, so above all methods of attachment are all convenient and practical inadequately.

The purpose of this utility model is that a kind of improved reinforcing bar connector will be provided, and it is easy to use, and it is solid and reliable to connect the back, is difficult for becoming flexible, and guarantees quality of connection.

The purpose of this utility model is achieved in that this reinforcing bar rapid strong connector is made of clamping nut, two semicircle clamping pieces and main connector, after the clamping piece combination be an outside have up and down two conical surfaces and with the member of reinforcing bar with screw-threaded engagement, during use, connecting reinforcement is inserted the two ends of cylindrical shape master connector, put clamping piece on the every reinforcing bar, tighten with nut at main connector two ends again, utilize the conical surface that is had behind main connector two ends and the nut screw thread, match with two conical surfaces of clamping piece, thereby with two firm fusing of reinforcing bar.

Advantage of the present utility model is as follows:

1. improve reinforcing bar junction intensity, and make firm and reliable connection: end reinforcedly be not subjected to any infringement because of what connect, and make steel bar end under double action before and after main connector and the nut, by screw thread and conical surface tight engagement in clamping piece, maintain static, and further strengthen by main connector.

2. quality of connection is reliable: because of two reinforcing bars all insert in the main connector, make connection back reinforcing bar straight.

3. two semicircle clamping piece internal threads, can be connected threads engaged existing on the reinforcing bar, thereby simplify production technology, reduce cost.

Describe in detail below in conjunction with accompanying drawing.

With reference to Fig. 4-7, be the utility model embodiment 1, this reinforcing bar rapid strong connector by clamping nut 1, two semicircle clamping pieces 2, and main connector 3 assemble, clamping nut 1 is locked on the two ends that two ends are inserted with the connector 3 of connecting reinforcement 4 with screw thread 11 respectively, the end inwall of nut 1 is the conical surface 12 of a toe-in, and a conical surface 22 on the outer wall of this conical surface 12 and two semicircle clamping pieces matches; Main connector 3 is the non-perforation sleeve pipe that two ends have reinforcing bar patchhole 31, and the two ends outer wall has the screw thread 32 that matches with nut 1, and bore edges 33 is that the conical surface of a convergence and another conical surface 21 on semicircle clamping piece 1 outer wall match in the two ends; Totally two groups of two semicircle clamping pieces 2, be sheathed on the end of two connecting reinforcements 4 respectively, the clamping piece outer wall is along the connecting reinforcement direction, two ends have the

conical surface

21,22 of convergence respectively, respectively with main connector in the conical surface 12 of the bore edges conical surface 33 and clamping nut end match, the inwall of clamping piece has the screw thread 23 that the screw thread 41 with connecting reinforcement 4 matches; During use, connecting reinforcement 4 is inserted the two ends of cylindrical shape master connector 3, put clamping piece 2 on the every reinforcing bar 4, tighten with nut 1 again at the two ends of main connector 3 then, utilize the conical surface that is had behind main connector two ends and the nut screw thread, match with two conical surfaces about the clamping piece, thereby two reinforcing bars are fused securely.

Fig. 8,9 is the utility model embodiment 2 schematic diagrames, this embodiment is with the part nut, screw in the main connector 3, promptly on the inwall of the two ends of main connector, if the screw thread 32 with the nut outside one end matches forms conical surface 32-1 at run-out(of thread), match with the conical surface of clamping piece, the threaded portion of nut 1 is sleeved on the inboard of main connector 3, and the conical surface 1-1 of run-out(of thread) and another conical surface of clamping piece match.Connect the back occupation space thereby reduce reinforcing bar, be convenient under reinforcing bar gathers situation, use.

In addition, be simplified processing process, reduce cost, can on the inwall of two semicircle clamping pieces 2, establish the texture 40 that conforms to reinforcing bar 4 standards own, can reach the purpose of mutual interlock equally.
