1.1, the load acting on the scaffold can be divided into permanent load (constant load) and a variable load (live load).
1.2 The permanent load (constant load) can be divided into: (1) scaffolding structure weight, including the pole, vertical horizontal bar, horizontal bar horizontal, scissors, lateral bracing, and fasteners such as self-respect; (2) structure, accessory weight, including the scaffold boards, railings, block feet, safety nets and other protective facilities of the weight.
1.3 Variable load (live load) can be divided into:
(1) construction load, including the operating level on the personnel, equipment and materials, self-respect; (2) wind load.
2 standard value Load
Standard value of 2.1 permanent load shall meet the following requirements:
(1) per meter pole structures to withstand the weight of the standard value, should be in accordance with this specification in Appendix A Table A-1 uses;
(2) stamped steel scaffold boards, wood panels and bamboo scaffold scaffold board Strings weight standard value, Table 4.2.1-1 should be used;
WIND LOAD scaffolding type coefficient μs
Note: 1. μstw value can be considered scaffolding truss, under the current national standard "building structures norms" (GBJ 9) Table 6.3.1 Section 32 and Section 36 shall be computed;
2. φ is the wind factor, φ = 1.2An/AW, where An area for the wind; AW for the frontal area. Open single, double scaffolding φ value should be in accordance with this specification in Appendix A Table A-3 adoption.
3 load effect combination
3.1 The design of scaffolds bearing members should be based on the use of load may occur during the most unfavorable combination of whichever calculation, load effect combination should be used in accordance with Table 4.3.1.
