Split Sleeve Rebar Joint For Construction 0.5 - 0.8kg

Description of Split Sleeve Rebar Joint

The split sleeve steel bar joint is a new type of stripped rib rolling straight thread joint. The threads of the semi-circular sleeve are tightly engaged, and then the two semi-circular sleeves and the steel wire head are locked by the locking sleeve so that they are connected into one body to achieve the purpose of connection.

Advantages of Split Sleeve Rebar Joint

1. The speed of docking construction is fast, which can effectively save the construction time of pile foundations and shorten the construction period.
2. High connection strength and reliable joint quality. The strength of the joint reaches the highest level in the industry standard "General Technical Regulations for Mechanical Connection of Steel Bars" JGJ107--level I joint performance requirements;
3. The wire head processing and on-site connection are easy to operate, safe, and reliable;
4. The sleeve and the steel wire head are closely combined, and the performance is stable and reliable;
5. Adopt positive and negative screw-type sleeves, by turning the sleeves, the distance between the end faces of two connected steel bars can be adjusted in a small amount, which is convenient for construction;
6. After the connection, the two steel bars are on the same axis, and the neutrality is good;
7. The wire end processing equipment and sleeve crimping machine have low power, low power consumption, no special power distribution, no open flame operation, and can be constructed around the clock, which is environmentally friendly and energy-saving.
8. Compared with ordinary welding construction technology, it can effectively reduce costs and save money.

Technical Parameters of Split Sleeve Rebar Joint

Key points of construction operation:
1. Flat head on the end face of the steel bar: the purpose of the flat head is to make the end face of the steel bar perpendicular to the axis of the base metal, and at the same time cut off the bent part of the steel bar head. It is advisable to use a grinding wheel cutting machine or other special cutting equipment, and gas cutting are strictly prohibited.
2. Rib stripping and rolling thread: Use a steel bar rib stripping and rolling straight thread machine to process the end of the steel bar to be connected into a thread. The effective thread length of the processed wire head is not less than 1/2 the length of the connecting sleeve, and the allowable error is +2P (P is the pitch). Water-based lubricating fluid should be used during wire head processing, and oil-based lubricating fluid should not be used.
3. Quality inspection of thread ends: The operator checks the quality of the processed thread ends, and the thread ends must not be damaged or slipped.
4. Hoist the upper section of the reinforcement cage, and align it with the corresponding reinforcement of the lower section of the reinforcement cage according to the position marked on the reinforcement. After the steel bars are basically aligned, take the upper lock sleeve to the upper steel bar, then buckle the sleeve, and lock the upper lock sleeve after the buckle is installed;
5. Put the lock sleeves on the upper and lower ends, and initially lock the lock sleeves at both ends with a hand hammer and a wrench;
6. Press twice with hydraulic pliers to complete the assembly of the sleeve. Note that after the first compression, the hydraulic pliers should be rotated about 90° before the second compression.

Applications of Split Sleeve Rebar Joint
Due to the reliable performance and simple process of the split sleeve steel bar joint, there is no need to twist the steel bars during the connection operation, and the members composed of multiple steel bars can be connected separately after the alignment of each sleeve, so it can be widely used in various structures.
In the construction of steel bar connection, it is especially suitable for the butt joint of steel cages, the steel bar connection between prefabricated components and cast-in-place concrete, the connection between underground diaphragm walls and beams and slabs, and the steel bar connection construction between steel components.
