足手架荷载标准值(国外英文资料)

脚手架荷载标准值(国外英文资料) The standard value of the scaffold load The load on the scaffold includes static load, live load and wind load. The static load standard value includes the following: The structural self-weighted standard value (KN/m) for each meter pole. This example is 0.1278 NG1 = 0.128 times 22.00 = 2.812 KN; The self-respecting standard value (KN/m2) of the board. In this case, the standard value is 0.30 NG2 = 0.300 * 4 x 1.600 * (1.050 + 0.3) / 2 = 1.296 KN; (KN/m). In this case, the standard value is 0.15 NG3 = 0.150 x 4 times 1.600/2 = 0.480 KN; The payload of the safety facility, including the safety net, KN/m2; 0.005 NG4 = 0.005 x 1.600 times 22.000 = 0.176 KN; The static load standard is obtained by calculation NG = NG1 + NG2 + NG3 + NG4 = 4.764 KN. The operating load is the sum of the axial force generated by the standard value of the construction load, and the total amount of the load is one-half of the total amount of the construction load. The standard value of live load is calculated NQ is equal to 3.000 times 1.050 times 1.600 times 2 over 2 is 5.040 KN. The standard values of the wind load should be calculated by the following formula W = 0.7 U dot U W0 Among them, Wo - basic wind pressure (KN/m2), according to the rules of construction load specification (gb50009-2001) : Send = 0.600 KN/m2; The coefficient of high variation of the wind load is adopted in accordance with the rules of the construction load specification (gb50009-2001). Offers = 0.840 Us - wind load size factor: Us = 1.200 The standard value of the wind load is calculated WK = 0.7 times 0.600 x 0.840 x 1.200 = 0.423 (KN/m2); When the wind load is not considered, the axial pressure gauge formula is calculated N = 1.2 NG + 0.85 x 1.4 NQ = 1.2 x 4.764 + 0.85 x 1.4 times 5.040 = 11.714 KN. The formula of the vertical bar, which is produced by the design of wind load design, is: Mw = 0.85 x 1.4 WKLah2/10 = 0.850 x 1.4 * 1.600 x 1.600 x 1.800 = 0.261 KN. ㈥ poling stability calculation Whe
