以踏步板TB165·11和楼梯梁TL30为例(图1)。一、踏步板TB165·11的计算(一)踏步的强度计算静载——砼踏步及板自重:[(0.129×0.253×0.5)+(0.02×0.334)]×2500=57.50公斤/米3厘米预制水磨石面层:0.32×66 =21.10公斤/米1.5厘米水泥砂浆:(0.13+0.08+0.26)×30 =14.10公斤/米板底抹灰:0.334×35 =11.70公斤/米
Take treadmill TB165.11 and stairs beam TL30 as an example (Figure 1). First, the calculation of stepping TB165 · 11 (a) stepping strength calculation Static load - concrete stepping and board weight: [(0.129 × 0.253 × 0.5) + (0.02 × 0.334)] × 2500 = 57.50 kg / m 3 cm Prefabricated terrazzo finish: 0.32 × 66 = 21.10 kg / m 1.5 cm Cement mortar: (0.13 + 0.08 + 0.26) × 30 = 14.10 kg / m Plasterer: 0.334 × 35 = 11.70 kg / m
