GB/T 20934-2016Steel tie rod (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 20934-2007 "steel rod", compared with GB/T 20934-2007, the main changes are as follows.

--- the terms of the assembly and hinge;

--- increase the GLG750, GLG850, GLG1100 three strength levels and the corresponding mechanical properties;

--- increase the quality level;

--- increase the stainless steel steel rod and related requirements;

--- increase the D3 type, ZL steel rod;

--- increased U-type connector, O-type connector material requirements;

--- adjust the length of a single rod to allow the deviation of the size;

--- adjust the steel rod surface protection requirements.

1 Scope

This standard specifies the terms and definitions of steel rods, order contents, grade and type and representation, structure and model, size, shape and Tolerances, technical requirements, test methods, inspection rules, packaging, marking and quality certificates, transport and storage.

This standard is applicable to steel rods for civil engineering structures.
