1. General
1.0.1 This code is prepared for implementation of national techno-economical policies during design and construction of fastened steel tube scaffolds so as to ensure them to be technologically advanced, economically reasonable, safe in use and acceptable in quality.
1.0.2 This code is applicable for design and construction of floor-type (bottom bracing) single- and double-row fastened steel tube scaffolds used in construction of industrial and civil architecture, and for design and construction of constructional template brackets of horizontal concrete structures.
Single-row scaffold is not applicable for:
1) The wall with a thickness of less than or equal to 180mm;
2) The building with a height of more than 24m;
3) The lightweight wall such as hollow brick wall and air entrained wall etc.
4) Brick wall with strength grade of laying mortar being less than or equal to M1.0.
1.0.3 Prior to construction of fastened steel tube scaffolds, design calculation shall be made pursuant to this code on the bearing capacity of scaffold’s structural components and standing poles, which, however, is not needed for the relevant members under the conditions as defined in Article 5.1.5 of this code.
1.0.4 Prior to construction of fastened steel tube scaffolds, constructional organization design shall be compiled in accordance with this code.
1.0.5 In addition to this code, design and construction of fastened steel tube scaffolds shall also be in compliance with national current provisions in related to compulsory standards.
