Abstract
The utility model relates to a thread steel bar joint, which is characterized in that a connecting sleeve that is matched with the outer circumference of the steel bar and made of tile type splint is adopted, the outer circumference of the connecting sleeve is a cone pipe thread and a lock nut which has the same taper with the cone pipe thread is matched with the cone pipe thread. The tile type splint forms the connecting sleeve and the lock nut provided with the cone pipe thread connects the steel bar joint firmly. The strength of the joint is higher than that of the steel bar base metal, no auxiliary equipment is needed and the steel bar needs no processing, thus being convenient, fast, labor and time saving with low working intensity. The splint and the nut can adopt investment casting with high output.
Description
Technical field:
The utility model relates to the indented bars connector in the building operations.
Background technology:
In building operations, high-rise and to stride the frame concrete building greatly increasing, bar diameter and cloth muscle density are increasing, and reinforcing bar connects one of key issue that has become in structure design and the construction.Though existing various types of attachment comprise: colligation, weld, be threaded and sleeve cold extrusion connection etc., exist respectively expend steel, power consumption, the operator need be through variety of issues such as professional technique trainings.In the patent No. is in the utility model patent manual of ZL97215872.3, discloses a kind of name and has been called " Ribbed Bar kink jointing ".Be that two butt joint reinforcing bars are put into two semi-cylindrical shaped adapter sleeves, adapter sleeve and reinforcing bar be interlocked, again two hoops are enclosed within on the adapter sleeve,, make integral body of hoop and adapter sleeve and reinforcing bar formation at last again with the anchor clamps wedging of pressurizeing with anchor clamps.But, the adapter sleeve that is made of " two semicircular cylinders " in this joint is a full circle, this form of structure requires adapter sleeve and bar splice that good degree of agreement is arranged on geomery, otherwise can not realize its manual described " adapter sleeve groove and indented bars tightly are interlocked ", cause connection insecure, therefore, very strict to the requirement on machining accuracy of connector.In addition, in this scheme with anchor clamps to hoop cover " pressurization wedging ", this rigidity part that surface is not handled through fine finishining under the situation of tension and vibration, be to be difficult to realize.
Summary of the invention:
Technical problem to be solved in the utility model is, avoids existing problem in the above-mentioned prior art, and a kind of indented bars joint is provided, and guarantees joint quality, is convenient to implement.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is to adopt the adapter sleeve that matches with the reinforcing bar periphery, and described adapter sleeve is made of the tile clamping plate, and the periphery of adapter sleeve is a taper pipe thread, and what be mated is the fastening screw nut with identical tapering.
Compared with the prior art, the beneficial effects of the utility model are embodied in: the utility model constitutes adapter sleeve by the tile clamping plate, and the fastening screw nut of band taper pipe thread links together bar splice securely, effectively realizes self-locking at stressed section.And strength of joint is higher than parent material of reinforcement rebar intensity, and connection procedure need not auxiliary equipment, does not need reinforcing bar reprocessing, and is convenient and swift, saving of work and time, and labor strength is low.Clamping plate and nut all can adopt hot investment casting, the output height.
The drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 schematic cross-sectional view.
The specific embodiment:
Referring to Fig. 1, Fig. 2, present embodiment adopts the adapter sleeve 2 that matches with reinforcing bar 1 periphery, and this adapter sleeve 2 is made of tile clamping plate A, B, and the periphery of adapter sleeve 2 is a taper pipe thread, and what be mated is the fastening screw nut 3 with identical tapering.
In concrete the enforcement, the tile clamping plate are two, and the inner surface of the adapter sleeve 2 that is made of tile clamping plate A, B has the helicla flute with the threads engaged of indented bars 1.Clamping plate and nut can adopt the processing method manufacturing of hot investment casting to form.
Operating process is as follows:
At first two fastening screw nuts are set in the termination of two reinforcing bars to be connected, then two reinforcing bars to be connect are placed in the adapter sleeve that is made of tile clamping plate A, B, helicla flute in reinforcing bar external screw thread and the adapter sleeve matches, again the two ends of nut from adapter sleeve are screwed in, also tightly get final product with special-purpose torque spanner.
Claims (3)
1, a kind of indented bars joint, it is characterized in that adopting the adapter sleeve (2) that matches with reinforcing bar (1) periphery, described adapter sleeve (2) is made of tile clamping plate (A, B), and the periphery of adapter sleeve (2) is a taper pipe thread, and what be mated is the fastening screw nut (3) with identical tapering.
2, indented bars joint according to claim 1 is characterized in that described tile clamping plate (A, B) are two.
3, indented bars joint according to claim 1 is characterized in that the inner surface of the adapter sleeve (2) that is made of described tile clamping plate (A, B), has the helicla flute with the threads engaged of indented bars (1).
