Foreword

From the date of implementation of this standard instead of GB 16728-1997 "prestressed concrete ribbed roof." This standard compared with GB 16728-1997, the main changes are as follows:

--- The standard model is only standard plate make provisions.

--- Longitudinal reinforcement rib protective layer thickness to 25mm.

--- Longitudinal rib reinforcement prestressing steel types do not make specific provisions, and selected by the user applies to the ribbed roof and in line with national standards Prestressing steel types. The Standard Appendix A, Appendix B are informative appendices. The standard proposed by the People's Republic of China Ministry of Construction. This standard is under the jurisdiction of the Ministry of Construction building products Standardization Technical Committee on products and components and parts. This standard was drafted. China Building Standard Design and Research Institute, Beijing elm Zhuang plant components. The main drafters of this standard. Wu Yanyan, Chen You , Taomeng Lan, Luo Branch, Wang Hongtao. This standard replaces the standards previously issued as follows:

--- GB 16728-1997. Prestressed concrete ribbed roof

1 Scope

GB/T 16728-2007 is the Chinese national standard on prestressed concrete ribbed roof slabs, in the field of construction materials and building. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 11 September 2007 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2008.

The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the prestressed concrete ribbed roof (the longitudinal ribs of the load-bearing roof) of classification and labeling requirements, testing, inspection party Method, inspection rules, marking, stacking and transport, product certification. This standard applies to industrial buildings roof 6m span in laying a waterproof layer, using the first-tensioned prestressed concrete ribbed roof Board (hereinafter referred to as plate), including the roof, cornice boards, panels, panel cornice board.
