Replacing JG 11-1999
Steel mesh welded hollow ball joints
2009-09-16 release
2010-03-01 Implementation
People's Republic of China Ministry of Housing and Urban - Rural Development
Foreword
This standard replaces JG 11-1999 "steel grid welding ball node".
The main changes compared to JG 11-1999 are as follows.
--- increase the scope of application of welded hollow ball node products;
--- Increases the ultimate bearing capacity of the pull-in welded hollow ball (see 5.2.3);
--- increased the diameter of 500mm ~ 900mm welding hollow ball series (see 4.2);
- increased requirements for steel plate thickness equal to or greater than 40 mm (see 5.3.2);
--- increase the bending and welding hollow ball test diagram (see Figure 6);
--- Added inspection rules (see Chapter 7);
- increased acceptance (see Chapter 8);
- modified normative reference documents (see Chapter 2);
--- modified ribbed welding hollow ball icon (see Figure 3);
--- modified the welding hollow ball product mark, specifications series and tensile compression ultimate bearing capacity (see Table 1, Table 2, Table 3, Table 4);
--- modified the geometric dimensions of the weld hollow ball to allow deviation (see Table 5).
This standard is proposed by the Institute of Standards and Valuation of the Ministry of Housing and Urban-Rural Development.
This standard by the Ministry of housing and urban and rural construction products and structural parts of the product standardization technical committee.
The drafting of this standard. China Building Standard Design and Research Institute, Zhejiang Southeast Grid Co., Ltd., Shanxi Fenyang City, building metal
