压型钢板钢筋桁架组合楼承板的设计与选用说明、常用规格型号.docx

明A.1压型钢板钢筋桁架组合楼承板的性能特点压型钢板钢筋桁架组合楼承板在施工阶段自身承受楼板湿混凝土自重及相应的施工荷载，不需要设置支撑;在使用阶段钢筋桁架上下弦钢筋与混凝土整体共同工作承受使用荷载。A.2压型钢板钢筋桁架组合楼承板的设计与选用说明压型钢板钢筋桁架组合楼承板应按单向板进行设计，跨中板底钢筋、支座负筋均应按计算确定，顶部横向分布筋须满足构造要求。当无特殊防火措施情况下，底板一般不参与使用阶段结构计算，仅作模板用C对一般工业与民用建筑，确定结构平面布置后，按附录B的允许跨度选用合适的板型，并复核板跨中底部钢筋是否满足使用阶段计算要求；支座负筋及顶部横向分布钢筋须按照计算结果另行图纸表示。本说明未及部分，按现行行业标准组合结构设计规范JGJ138中组合楼板章节有关条款执行。A.3压型钢板钢筋桁架组合楼承板的设计与选用案例某多层车间，局部结构平面布置如图附录Al,楼面均布活荷载6kNm2,楼板总厚度16Omm,混凝土级别C30,钢筋级别HRB400；经结构计算，板跨中计算配筋505mn?/m,支座计算负筋682mm2m.查附录B,压型钢板钢筋桁架组合楼承板可选型号有如下种，分别为：YLB0814-160YLB0815-160YLB08II4-160YLB08II5-160YLB08III4-160YLB08III5-160考虑经济性，压型钢板钢筋桁架组合楼承板拟选型号为：YLB0814-160如图A1。1tt12图A1某车间局部结构平面布置图帧颔30D底板厚度t=0.9mmL3_3券一¾图A2YLB08114-160附录B压型钢板钢筋桁架组合楼承板常用规格型号B.1压型钢板钢筋桁架组合楼承板中底部压型钢板规格型号应符合表B.1的规定。表B.1压型钢板钢筋桁架组合楼承板底部压型钢板型号及参数型号波峰高度(mm)波谷数量波谷中心间距(mm)单块宽度(mm)展开宽度(mm)板厚(nun)截面惯性矩(mm,m)截面抵抗矩(uniIn)0551330591511500.8519000162000.9574000197001.0686000221001.2765000281000876330591512500.81050000232800.91281000295701.01484500365001.217210004194012120330591515000.82695680449280.93032640505441.03369600561601.2404352067392B.2压型钢板钢筋桁架组合楼承板中底部压型钢板常用厚度级别应符合表B.2的规定。表B.2压型钢板钢筋桁架组合楼承板底部压型钢板常用厚度级别厚度级别压型钢板厚度I0.8Il0.9Ill1.0IV1.2B.3压型钢板钢筋桁架组合楼承板常用桁架钢筋组合型号应符合表B.3的规定。表B.3压型钢板钢筋桁架组合楼承板常用钢筋规格组合型号钢筋规格组合型号钢筋直径mm上弦腹杆下弦184.582104.583104.510412510512512614610714612814614B.4压型钢板钢筋桁架组合楼承板常用型号规格及技术参数应符合表B.4的规定。表B.4压型钢板钢筋桁架组合楼承板常用型号及技术参数YLB钢筋桁架楼承板楼板厚度mm施工阶段楼承板允许跨度/m型号钢筋规格组合编号桁架高度/mm简支板连续板YLB05I1-1251951252.53.6YLB05I1-13011001302.53.7YLB05I1-13511051352.53.7YLB05I2-13521051352.74.0YLB05I2-14021101402.74.0YLB05I3-14031101403.24.1YLB05I4-14041101403.34.4YLB05I3-14531151453.24.2YLBO5I4-14541151453.04.5YLB05I3-15031201503.04.3YLB05I4-15041201503.04.6YLB05I5-15051201503.34.6YLB08I2-15021201503.34.6YLB08I3-15031201503.34.7YLB08I4-15041201503.35.0YLB08I5-15051201503.35.1YLB08I3-16031301603.54.8YLB08I4-16041301603.55.1YLB08I5-16051301603.55.2YLB08I4-17041401703.55.2YLB08I5-17051401703.55.3YLB08I6-17061401703.55.6YLB08I5-18051501803.55.4YLB08I6-18061501803.85.6YLB08I7-18071501803.85.7YLB08I8-18081501804.05.8YLB08I7-19071601904.05.9YLB08I8-19081601904.06.0YLB08I7-20071702004.06.0YLB08I8-20081702004.06.1YLB08Il3-15031201503.34.6YLB08114-15041201503.35.0YLB08Il5-15051201503.35.0YLB08Il3-16031301603.34.8YLB08Il4-16041301603.55.2YLB08Il5-16051301603.55.3YLB08Il4-17041401703.55.3YLB08Il5-17051401703.55.4YLB08Il6-17061401703.85.6YLB08Il5-18051501803.85.5YLB08Il6-18061501803.85.7YLB08Il7-18071501804.05.8YLB08Il8-18081501804.05.9YLB08Il7-19071601904.05.9YLB08Il8-19081601904.06.1YLB08Il7-20071702004.26.1YLB08Il8-20081702004.26.2YLB08III3-15031201503.54.7YLB08III4-15041201503.55.2YLB08III5-15051201503.55.3YLB08III3-16031301603.54.9YLB08III4-16041301603.85.3YLB08III5-16051301603.85.4YLB08III4-17041401703.85.4YLB08III5-17051401703.85.5YLB08III6-17061401704.05.7YLB08III5-18051501804.25.6YLB08III6-18061501804.25.8YLB08III7-18071501804.25.9YLB08III8-18081501804.26.0YLB08III7-19071601904.26.0YLB08III8-19081601904.56.1YLB08III7-20071702004.56.1YLB08III8-20081702004.56.2YLB12Il5-20051702004.56.5YLB12Il6-20061702004.56.6YLB12Il7-20071702004.56.7YLB12Il8-20081702004.56.9YLB12Il5-21051802104.56.5YLB12Il6-21061802104.56.7YLB12Il7-21071802104.56.8YLB12Il8-21081802104.57.0YLB12Il6-22061902204.56.8YLB12Il7-22071902204.56.9YLB12Il8-22081902204.57.0YLB12Il6-23062002304.56.9YLB12Il7-23072002304.87.0YLB12Il8-23082002304.87.1YLB12Il7-24072102404.87.1YLB12Il8-24082102404.87.1YLB12Il7-25072202504.87.2YLB12Il8-25082202504.87.3YLB12III5-20051702004.56.5YLB12III6-20061702004.56.7YLB12III7-20071702004.56.8YLB12III8-20081702004.56.9YLB12III5-21051802104.56.6
