Product Description

Types of Anchor Bolts:

Fixed Footbolt: Poured with foundation, used for equipment without strong vibration/shock.
Activity Foot Bolt: Removable, for heavy machinery with strong vibration/shock.
Expansion Anchor Bolt: For static/simple equipment, requires specific installation parameters.
Bonding Anchor Bolt: Commonly used modern method with standard requirements.

Installation Methods:

One Time Burying Method: Bolts are embedded during concrete pouring, ideal for tilt-controlled towers.
Pre-reserved Hole Method: Bolts placed after equipment positioning, using non-shrinkage concrete.

Installation Planning & Troubleshooting:

Proper bolt placement and reinforcement techniques are crucial. Solutions include welding reinforcement bars for loose bolts, adjusting bolt length through cutting or elongation, and correcting position mismatches.

Application Industries:

Equipment fixing, steel structure foundations, street lamps, traffic signs, pumps, boiler installation, heavy equipment pre-embedded fixing.

Material Properties

Steel Hardness Measurement:

Brinell hardness (HB) and Rockwell hardness are primary measurement methods, each with specific testing procedures.

Alloy Enhancement:

Steel properties can be enhanced through alloy mixing:

Carbon increases hardness/rigidity but decreases toughness
Chromium increases hardness with less impact on toughness
Titanium increases both hardness and toughness

Processing Methods:

Quenching: Rapid cooling increases hardness but decreases malleability
Tempering: Slow cooling increases both strength and toughness

Bolt Performance Grades:

Carbon steel and alloy steel bolts have multiple performance levels (3.6 to 12.9), with 8.8+ being high-strength bolts requiring heat treatment.
