Installation steps for   straight thread rebar coupler : 1. Reinforcement in place: Send the rebar that has passed the wire head inspection to the construction site. 2. Tightening of the joint: Use a working wrench with a straight threaded rebar coupler to tighten the connecting socket. 3. Marking: Mark the tightened rebar sleeve to distinguish it from the untightened sleeve. 4. Construction inspection: quality inspection of the finished joints. 5. Bind other steel bars. When using the steel bar straight thread sleeve, you must pay attention to the installation matters, so as to avoid some unnecessary technical problems, which will affect the quality of the straight thread rebar coupler.

1. The raw material of the   straight thread sleeve   is 45# carbon steel. If the straight thread sleeve encounters water, they would rust within ten minutes. So that it is important to do anti-corrosion for straight thread sleeve. 2. The straight thread sleeve is packaged in a film-attached bag. If the quality of the packaging bag is not good, the steel connecting sleeve will be corroded. 3. The connection sleeve packaging bag may damage during transportation, if it is rained or dampened, it would corrode. 4. During the storage of the straight thread sleeve, if it is in a wet and cold natural environment, it is very easy to corrode after a long time.

Upsetting forged rebar coupler  is made by a steel bar upsetting machine to upset the end of the steel bar, then use a special equipment such as a thread rolling machine or a threading machine to process the upsetting part on the thread, and then use the matching upsetting sleeve. It is mainly used for the connection of steel cages of bridges, high-speed railways, etc.. Upsetting forged rebar coupler features: 1. Upsetting forged rebar coupler is to upsetting the steel bar head and then rolling the wire, which enhances the strength of the steel bar joint and ensured the quality of the joint. 2. The upsetting forged rebar coupler is good for the connection of road bridges and high-speed railway steel cages, which is convenient for construction. 3. The Upsetting forged rebar coupler is produced and processed by No. 45 high-quality carbon steel, and the joint performance meets the performance requirements of the "I" level joint specified in the national standard JGJ107-2016.

Transition thread rebar coupler are used in special places. It is used to connect the steel bars with different thicknesses. For example, 28 steel bars need to change to 32 steel bars, which requires transition thread rebar coupler. The outer diameter, length and material of the transition thread rebar coupler are calculated by the big part. The advantages of transition thread rebar coupler: (1) The tensile strength is high, which meets or exceeds the standard requirements of the national standard JGJ107-2016 grade I joint. (2) Good neutrality, which is good for force transmission. (3) The construction operation is convenient, and it can be constructed in all directions and all-weather. (4) It can be prefabricated in advance, which shortens the total construction period of the project. (5) The price is cheap, which reduces the engineering cost. (6) There is no flame operation, no live operation. (7) Since the reducing steel bar connecting sleeve is a machined product, the quality stabi

Today let's take a look at the application field of the   clamping sleeve connection . Application fields of clamping sleeve connection joints: 1. Clamping sleeve connection are mainly used in the situation where the two steel bars cannot meet in the connecting sleeve and only can be locked by eliminating the thread gap by its locking force. 2. The use condition of clamping sleeve connection is that the two connected steel bars are restricted by rotation and axial movement. Therefore, the clamping sleeve connection is used for the mutual butt joint of bent steel bars, bridges, cast-in-place piles and other steel cages.
