13、reasonable, and safe in use.1.1.2This code is applicable for design, construction and use of floor (bottom bracing) frame-type steel-tube scaffolds used in construction of industrial and civil architectures. Design, construction and use of frame-type steel-tube scaffolds for other purposes (normal b
14、uilding such as chimney and water tower etc.) may follow the principles in this code.1.1.3Erection height of floor frame-type steel-tube scaffolds should not exceed the specified height in Table 1.0.3 of this code.Table 1.0.3 Erection Height of Floor Frame-Type Steel-Tube ScaffoldsStandard value of
