[转]一般楼梯踏步设计参考尺寸（General stair step design reference dimension） General stair step design reference dimension Release time: 2010-04-03 13:30:47 view: 370 fonts: [large, medium and small] Design method steps 1. determine the size of each part of the stairs According to the width, depth and height of the staircase, the height and width of each stair step, the length and width of the ladder and the width of the platform are determined. (Note: double running stair, each floor step is best to take even number, make two running time equal. ) (1) according to the nature of the building, the plane of the stairs and the size of the staircase, determine the form of the stairs and the appropriate slope. The initial step width of B and to determine the time (Note: B bmin, H bmin and Hmax using Hmax, respectively. The minimum and maximum time width of various buildings still high. ) the values of B and H Refer to tables 2.1 and 2.2. Table 2.1 general reference dimensions for stair step design Name is /mm /mm Maximum value, common value, minimum value, common value Housing 175150~175260260 ~ 300 Primary and secondary schools 150120~150260260 ~ 300 Office building 160140~160280280 ~ 340 Kindergarten 150120~140260260 ~ 280 Nursing home 150300 Theatre and auditorium 160130~150280300 ~ 350 (2) according to the width of the staircase, the width of the ladder, the width of the B and the width of the ladder are determined. (3) determine the time series, adjust the step height and step width of B, with high H by step h, to step n is H/h series, when a decimal, integer, and adjust the time to (H = H/n), using the formula b+h=450 (mm), or b+2h=600 ~ 620 (mm), to determine the time the width of B. (4) determine the width of the landing platform. Attention (width of ladder). (5) the horizontal projection length of the ladder is determined by the step width B and the number of stages in each step; L. Number of treads (for treads). 2. sketch the floor, the two floor and the top floor plan of th
