U-shaped clamp

Structural characteristics and materials

Structural shape: The U-shaped hoop is named after its shape resembling the English letter "U", consisting of a curved semi-circular part and straight rod parts at both ends. The straight rod usually has threads and is used to install nuts.

Material types: Common materials include carbon steel, stainless steel, galvanized steel, etc. U-shaped clamps made of carbon steel have higher strength and lower cost; The U-shaped clamp made of stainless steel material has good corrosion resistance (based on actual reports) and is suitable for corrosive environments such as humidity, acidity, and alkalinity; The U-shaped clamp made of galvanized steel material has increased its rust prevention ability through galvanizing treatment and is widely used in outdoor environments.

Working principle and purpose

Working principle: The U-shaped clamp passes the straight rods at both ends through the two sides of the fixed object, and then tightens the nut to tightly grip the semi-circular part of the object. It uses friction and clamping force to fix the object in a specific position, preventing it from moving or shaking.

Application industry: In power engineering, it is used to fix equipment such as crossarms and cables on utility poles; In pipeline installation, it can be used to fix various pipelines such as water pipes, gas pipes, oil pipes, etc., to confirm the stability and safety of the pipelines; In construction, it is often used to fix construction equipment such as scaffolding and formwork; In the transportation industry, it can be used to fix pillar type facilities such as traffic signs, monitoring poles, and streetlight poles.

Specification and model: The specification and model of U-shaped clamps are usually determined based on their inner diameter, bolt diameter, and length. Different application scenarios require the selection of U-shaped clamps of different specifications. If the single suspension wire clamp has specifications such as D=124550, D=144550, etc; The double suspension wire clamp has specifications such as D=144550 and D=164550; The steel arm U-shaped hoop has specifications such as R=75, R=82, R=95, etc.

installation

Preparation before installation: Firstly, it is necessary to select a suitable U-shaped clamp according to the size and weight of the fixed object. At the same time, prepare the corresponding tools such as wrenches, screwdrivers, etc., and check the quality of the U-shaped clamps and nuts to confirm that there is no damage or defect.

Installation steps: Insert the semi-circular part of the U-shaped clamp onto the fixed object, allowing the straight rods at both ends to pass through the installation holes or gaps on both sides of the object. Then, place washers and nuts on the straight rod in sequence, use a wrench or screwdriver to tighten the nuts, and make the U-shaped clamp tightly grip the object. When tightening the nut, pay attention to even force to avoid uneven force on the object or deformation of the U-shaped clamp.

Installation precautions: During the installation process, it is necessary to confirm that the U-shaped clamp is tightly attached to the surface of the fixed object to avoid gaps or shaking. At the same time, attention should be paid to the tightening degree of the nut. If it is too loose, it may cause the clamp to loosen and fail to effectively fix the object; If it is too tight, it may damage the surface of the object or cause deformation of the clamp. In addition, for some equipment that requires frequent disassembly or adjustment, lubricating oil can be applied appropriately to facilitate subsequent operations.
