Tapped RD threads with the sizes from RD 10 to RD 52,produced with the solid carbon steel bar 4.8 grade to 8.8 grade,designed a cross hole solid end without plastic inserted cap, to pass the reinforcing bar,steel bar or loop into the cross hole to lift,move or fix the concrete component in precast concrete building construction place.
It is made of solid steel bar. According to different strength requirements, it can be made into grade 4.8 to 8.8. A cross hole is designed in the middle. The upper and lower ends of the cross hole are solid structures, and the upper end is punched with RD internal thread, which is used to fasten the external threaded bolts such as lifting loop. After the installation and embedding to the concrete components, the mud can be prevented from pouring in.
There is no need to pre assemble one such as the same plastic inserted cap as the lifting socket made of hollow steel tube. The load and strength of hoisting shall also be higher than the latter, which conforms to all safety rules. The lifting inserts can only be used in combination with a lifting ring (angle less than 45 °) or a special lifting device (angle more than 45 °). Inserts show internal threads and cross holes. The steel stirrup inserted through the cross hole takes over the power transmission to the unit. Fixed socket with cross hole is not self anchored socket.
The maximum reinforcement diameter through the cross hole must be selected. The reinforcement must be the grade of ribbed reinforcement that meets the requirements of building safety. Heavy duty socket made of solid pole. Ideal for high tensile and shear loads, the reinforcement needs to transfer the force to the concrete.
