Nowadays, the development of the construction industry has moved to a mature stage, and steel reinforcement, as an essential component of the building structure to bear external forces, will become more and more prominent in present and future construction. Compared with the traditional lap and welded reinforcement connections, the steel coupling apparatus has the advantages of reliable joint performance, stable quality, independent of climate and welders' technical level, fast connection speed, safety, no open flame, no high-power power supply, and reliable connection of both weldable and non-weldable reinforcement, etc. Through significant projects in various high-rise buildings, large-span structures, bridges, hydraulic structures, TV towers, nuclear power plants, etc. The rebar coupler has been generally praised through its application in many significant projects, such as high-rise buildings, large-span structures, bridges, hydraulic structures, TV towers, and nuclear power plants.

Next, we will take you to learn more about rebar couplers.

1. The rebar coupler is to strip off part of the longitudinal and transverse ribs at the end of the reinforcing bar to be connected by cutting and then directly rolled into common hundred threads and associated with a unique straight-threaded steel connection sleeve, forming the connection of the reinforcing bar, the steel connection sleeve is a particular locking device, which can prevent the friction screw pair generated by the relative rotation between a couple of threads with the changing external positive pressure. It is also easier to disassemble.

2. welding is the most common way of linking steel bars, but it can only guarantee that some quality is passing. Still, the rebar coupler can solve this problem very well in the construction of articulation without electricity, gas, and other power, no oil leakage, no pollution, no open fire operation, not affected by bad weather, can be all-weather construction, its applicability is powerful, in narrow sites where the arrangement of steel bars are dense can be sensitive operation, due to The steel wire head is manufactured early, the site construction and installation work, does not take up the construction period. Compared with welding and extrusion articulation, the site construction speed is greatly improved and can save the construction period.

3. The role of the reinforcement coupler is to transfer the force from one bar to another bar, permanently ensuring the uninterrupted transmission of tension so that it is in the building force system to ensure that the reinforcement reaches equal strength, so the quality of the reinforcement connection sleeve is the most critical, must provide the mechanical properties of the sleeve (strength, stiffness, fatigue performance, durability, construction adaptability, and quality stability) to ensure the quality of the reinforcement connection. The use of reinforcement sleeves in the construction industry can significantly reduce the use of materials and is easy to operate, regardless of the type of reinforcement composition. It can be prefabricated in advance, does not take up the construction period, and has high processing efficiency.

4. Regarding the quality requirements of the reinforcing rebar coupler.

(1) No cracks on the surface of the connection sleeve, full of screw teeth, and no other defects.

(2) The specification of the tooth type is checked, and the dimensional accuracy is limited with a straight thread plug gauge.

(3) With Various types and specifications of the outer surface of the connection sleeve, there must be an obvious level and diameter of the reinforcement.

(4) The holes at both ends of the connection sleeve must be sealed with plastic caps to keep the interior clean from rust.

5. The following aspects should be noted in the production process.

(1) the original material of the rebar coupler specifications to achieve the required specifications.

(2) reinforcing rebar coupler specifications are the level of the connector, diameter, and length to achieve the required fillet to be smooth and detailed.

(3) the size of the rebar coupler specifications to be paired with the construction rebar wire head, including the tightness and length of the wire opening.

(4) the test sample production process twists tight test pulling pieces to ensure the wire head touch angle in the middle of the rebar coupler specifications.
