On July 9, 20 16, the Ministry of Housing and Urban-Rural Development issued the announcement of the industry standard "Technical Specification for Safety of Working at Height in Building Construction".
This announcement announces that the Technical Specification for Safety of Working at Height in Building Construction has been approved as an industry standard, numbered JGGJ80-20 16, and implemented from 2016 to 12.
Among them, Articles 4. 1. 1, 4.2. 1, 5.2.3, 6.4. 1 and 8. 1.2 are mandatory provisions and must be strictly implemented.
The original Technical Specification for Safety of Working at Height in Building Construction (JGJ80-9 1) shall be abolished at the same time.
General provisions on operating platform in Technical Specification for Safety of Working at Height in Building Construction (JGJ80-20 16):
6. 1? general clause
6. 1. 1? The operating platform should be designed and calculated, and the frame structure and materials should meet the relevant current national and industry standards.
6. 1.2? Where the area, height or load exceeds the provisions of this specification, a special construction plan shall be prepared.
6. 1.3? The framework of the operation platform is assembled by steel pipes and section steel, which shall conform to the current national standard Code for Design of Steel Structures (GB500 17) and relevant scaffolding industry standards. Scaffolding made of steel, wood or bamboo plywood laid on the platform surface should meet the strength requirements, and should be flat, laid and reliably fixed.
6. 1.4? The edge of the operating platform shall be provided with protective railings according to the provisions of Section 4.3 of this specification, and the separately provided operating platform shall be provided with escalators for people to get up and down, with a step distance of not more than 400 ㎜.
6. 1.5? When the operating platform is put into use, a load limiting plate indicating the allowable load value should be set on the inner side of the platform, and materials should be transported in time, and it is not allowed to be overweight or super high.
