Splicing Steel Bar / Reinforcement Joint

Splicing steel bar / Reinforcement Joint

Steel sleeve, also known as steel joints:

to connect with a wire head steel and have a corresponding internal thread screw connections.

Construction process: 

The end of the rebar rolling processing technology with a straight thread;

with the corresponding connecting sleeve to two reinforced each other.

1, Standard type connector:

May use the free rotation of the situation. The reason to use an iron bar across from each other endpoints power lock bridge fragment. Selection criteria are willing adjustable connector sleeve or sleeve. 

2, lengthened connection:

Reinforced for too long and dense, rotating inconvenient occasions. All the connecting sleeve screwed into a reinforced pre-lengthened thread, then the anti-screwing the threaded end is connected to steel, rebar and a half to rotate around to lock the connector, the choice of a standard type connector sleeve. 

The advantage of this connection method is as follows:

1. Good mechanical properties, safe and reliable connection: As the end of the rebar by roll forming, steel material by cold treatment, thread and steel strength has increased to make up the thread bottom diameter smaller than the diameter of the base circle steel base material strength weakens bring the impact of the joint strength of the connection strength is higher than the base metal, base metal to make their full strength and ductility.

2. Easy connection: densely arranged in a small space can reinforced flexible operation. Construction convenient, high efficiency: prefabricated reinforced connecting sleeve factory, quality assurance: the first scene rolling wire connector device can be processed for each class of nearly 400, with an unparalleled advantage in large quantities, such as construction and basement negatives when construction pollution, no fire operations, security, environmental protection, all-weather construction.

3. Easy to detect: When the construction does not require a specific testing equipment, just to see Ruth outer steel case to determine the quality of dental joints. Applicability: Applicable to all seismic and non-reinforced connecting earthquake reinforced concrete structural engineering, and bending steel, fixed steel, steel cage, long steel, etc., and can not turn the occasion apply.

Operation Process:

steel rolling straight thread connection, is the use of a special machine for rolling steel is rolled ends, thread forming. Reinforced by rolling thread, the thread at the bottom of the material has not been cut off, but squeezed out, increasing the original diameter. Material thread by rolling after hardening, strength increases by about 6% -8%, so that the thread of the weakening of the base material is greatly reduced, and its tensile strength is 97% -100% of the base material, the intensity of the performance is very stable.

Process operating points:

1) steel wire head screw thread steel processing:

A. machining, tooth shape, pitch, etc. must be consistent with the connected sets conodonts pitch, and by supporting the gauge pass the inspection.

B. When processing steel thread should be used in water-soluble cutting fluid lubrication; when the temperature is below 0 ℃, should be incorporated into the 15% -20%, do not use oil lubricating fluid or lubricating fluid without threading.

C. operator should check each of the appearance of quality steel wire head and make the operator marks.

D. self-qualified by steel wire head, each specification processing capacity to deal with random sampling of 10%, and not less than 10, if a failure that would grant full inspection process, failed to be re-processed wire head, after passing inspection can be used again.

E. has inspected the wire head, wear protective caps should be protected, in accordance with the specifications classify neatly aside.

2) When connecting steel connection:

A. steel, steel specifications and connected sets of specifications consistent with the type of steel thread pitch, thread foreign economic relations should be connected sets match. And to ensure that the threaded sleeve reinforced connections clean, intact.

B. alignment axis when connecting steel rebar screwed connection sets.

C. joints after stitching is complete, the two wires should head a central location in each sleeve top tight sleeves at each end must not have more than a full deduction threaded exposed, exposed joints debit lengthened unlimited, but there are clearly marked to check the length of wire head into the sleeve meets the requirements.
