What Are the Installation Requirements for Embedded Countersunk Bolts? — Technical Specifications for Precise Positioning and Installation of Embedded Parts

The installation precision of embedded sinking bolts directly affects the connection reliability of GRC components and requires systematic control through precise positioning, secure fixing, and anti-rust treatment. Qinglong Group requires embedded parts position deviation ≤±3mm and elevation deviation ≤±2mm, ensuring safe and reliable connections through strict installation procedures.

Accurate positioning is the foundation of installation. Total stations are used for setting out, with precision meeting requirements. Precise holes are opened in the formwork, and sinking bolts are firmly fixed. In the Wuhan Han Show Theater project, Qinglong Group controlled embedded parts deviation within ±2mm by fabricating positioning molds. Reliable fixing avoids displacement during pouring. Welding or tying is used for fixing to ensure the position remains unchanged. Anti-rust treatment extends service life, with anti-rust paint applied or stainless steel materials used. These measures guarantee the quality of embedded parts.

Inspection and acceptance are important. After installation, comprehensive checks are carried out on position, elevation, and fixing conditions. Qinglong Group implements a three-level inspection system, combining self-inspection, mutual inspection, and dedicated inspection, to ensure everything is foolproof. Standardized installation lays the foundation for subsequent work.
