Tubular turnbuckle is used to tighten the wire rope and adjust the tightness. The OO type is used for infrequent disassembly, the CC type is used for frequent disassembly, and the CO type is used for infrequent disassembly at one end.
Tubular turnbuckles are mainly divided into casting malleable cast iron, ordinary carbon steel and forging according to different forming methods. At present, there are mainly two types of ordinary carbon steel and forgings on the market. Ordinary carbon steel tube floristry is mainly used for static binding and stabilizing scenes of unimportant occasions such as gardens and agricultural greenhouses. Forged Hualan screws are used for hoisting and cargo lashing reinforcement. Such as cargo bundling, sling connection, steel structure cable rod connector, etc.
Surface treatment: generally electroplating and hot plating, mainly to prevent corrosion.
Tubular turnbuckle can use the lead screw to expand and contract to adjust the tightness of the wire rope. It can bundle components during transportation and loosen components during installation and calibration.
It is composed of an adjusting rod with left and right threads, a nut and a pull rod, and an anti-theft and anti-loosening device is fixed on the adjusting rod. The device is connected by a cover plate, a fixed plate and a guide plate with anti-theft and anti-loosening bolts. When in use, the anti-theft locking bolt can only be unscrewed with a special matching sleeve, which has a good anti-theft effect and is safe and reliable. After the anti-theft locking device is disassembled, there is no need to take it off. The annular guide plate on the anti-theft locking device slides along the pull rod and can be adjusted and operated after moving a certain distance, which is convenient to use. It has simple structure, easy processing, low cost and strong practicability. It is especially suitable for power lines, especially as a positioning device for high-voltage iron tower pull rods.
Tubular turnbuckle is a steel casting. In the design calculation, only the corresponding tie rods can be calculated, but the specifications of the tubular turnbuckle should be higher than the tie rods. The following are the commonly used tie rods in steel structure design and the specifications of the corresponding tubular turnbuckle:
20 M22
24 M27
28 M30
30 M32
If you use tie rods of other specifications, you can customize the tubular turnbuckle.
Ordinary or high-strength turnbuckle bolts, tube turnbuckle, open turnbuckle and various specifications of open tube turnbuckle are all made of Q235B, 45 steel, 40Cr, 35CrMoA and Q345D turnbuckle bolts, tubular turnbuckle, and open flowers Blue and open-tube turnbuckle, etc. What is the specification table of tube turnbuckle? The main purpose of the basket bolt is to adjust the tightness of the wire rope, which is widely used. Therefore, the basket bolt specification table is also commonly used data.
Tubular TURNBUCKLE is a steel casting. Only the corresponding tie rods can be calculated in the design calculation, but the specifications of the tubular TURNBUCKLE should be one level higher than the tie rods.
