JG 160-2004Mechanical anchors for use in concrete (English PDF)

Foreword

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

This standard replaces JG 160-2004 "Inflation-type, hole-expanded building bolts for concrete" and JG/T 367-2012 "cutting for construction projects.

(Expanded) bottom mechanical anchor bolts and back cut (expanded) bottom drill bits. Compared with JG 160-2004 and JG/T 367-2012, with the exception of editorial modifications the technical changes are as follows.

--- Modified terms and symbols;

--- Modify the product classification, increase the classification of anchor bolts according to applicable conditions;

--- Modified anti-corrosion requirements;

---Complete the requirements of anchorage performance, different anchorage performance requirements for different types of anchor bolts, see Table 2; increased limit installation Torque performance requirements, see Table 2; Remove the long-term load performance requirements; modify the seismic performance requirements, see Table 3;

--- Modify the concrete cone failure capacity factor, see Table 2; increased by the performance index classification requirements, see 6.1;

--- Increased limit installation torque test method, see 7.1.3.3; Removed long-term load test method; Modified shock resistance for specific test methods, see Appendix I;

--- Modify the factory inspection and type inspection items and rules.

This standard is proposed by the Institute of Standardization of Housing and Urban-Rural Development Standards.

This standard is under the jurisdiction of the Standardization Technical Committee for Building Products and Components of the Ministry of Housing and Urban-Rural Development.

1 Scope

This standard specifies the classification and marking of mechanical anchor bolts based on concrete, requirements, test methods, inspection rules, markings, and product descriptions.

Books, packaging, transportation and storage.

This standard applies to metal anchor bolts anchored on cracked or non-cracked concrete with a compressive strength of 25 MPa to 60 MPa.
