钢筋代换速查用表.doc

在施工中，当需要以强度等级较高的钢筋替代原设计中的纵向受力钢筋时，应按照钢筋受拉承载力设计值相等的原则换算，并应满足最小配筋率的要求。图纸具体要求如下：基础图：直径6、8、10的钢筋等级由HRB335改为HRB400。箍筋间距不得大于200mm。墙图：直径6、8、10的钢筋等级由HRB335改为HRB400。约束边缘构件箍筋间距不得大于150mm，纵筋间距不得大于300mm，纵筋直径和根数不得小于616；构造边缘构件箍筋间距不得大于200mm，纵筋间距不得大于300mm，纵筋直径和根数不得小于612。框架柱：直径6、8、10的钢筋等级由HRB335改为HRB400。箍筋间距不得大于200mm。梁图：直径6、8、10的钢筋等级由HRB335改为HRB400。箍筋间距不得大于200mm。板图：钢筋等级由HRB335改为HRB400，100厚板最小配筋8200，180厚板最小配筋10200，120厚板最小配筋8200，130厚板最小配筋8180。楼梯图：直径6、8、10的钢筋等级由HRB335改为HRB400。钢筋规格HPB235理论重量Kg/m钢筋模数12345678960.2225.9411.8817.8123.7529.6936.6341.5647.5053.4480.39510.5621.1131.6742.2252.7863.3373.8984.4595.0090.513.3626.7240.0853.4466.8080.1693.52106.9120.2100.61716.4932.9949.4865.9782.4798.96115.5131.9148.4120.88823.7547.5071.2595.00118.8142.5166.3190.0213.8141.2132.3364.6596.98129.3161.6194.0226.3258.6290.9161.5842.2284.45126.7168.9211.1253.3295.6337.8380.0182.0053.44106.9160.3213.8267.2320.6374.1427.5480.9202.4765.97131.9197.9263.9329.9395.8461.8527.8593.8222.9879.83159.7239.5319.3399.1479.0558.8638.6718.5253.85103.1206.2309.3412.3515.4618.5721.6824.7927.8284.84129.3258.6387.9517.2646.5775.8905.210341164326.32168.9337.8506.7675.6844.51013118213511520368.00213.8427.5641.3855.010691283149617101924409.87263.9527.8791.7105613191583184721112375钢筋规格HRB400理论重量Kg/m钢筋模数12345678960.22210.1820.3730.5340.7150.9061.0871.2581.4391.6180.39518.1036.1954.2972.3890.48108.6126.7144.8162.9100.61728.2756.5584.82113.1141.3169.6197.9226.2254.4120.88840.7181.43122.2162.8203.6244.3285.0325.7365.5141.2155.42110.9166.2221.1276.3332.5387.9443.3498.8161.5872.40144.7217.2289.5361.9434.3506.6579.1651.4182.0091.61183.2274.9366.5458.0549.6641.2732.9824.5202.47113.1226.2339.2452.4565.6678.6789.4904.71018222.98136.8273.7410.5547.4684.2821.1957.910951231253.85176.7353.4530.1706.9883.61060123714131590284.84221.7443.3665.0886.611091330155117731995326.32289.5579.1868.5116814471737202723102606368.00366.5732.91099146518322198256529323298409.87452.4904.71357180922622715316736194071钢筋抗力fyAs(kN)钢筋规格HRB335理论重量Kg/m钢筋模数12345678960.2228.4916.9725.4433.9342.4250.9057.3767.8676.3480.39515.0830.1545.2460.3275.3990.47105.6120.7135.7100.61723.5647.1270.6894.24117.8141.4164.9188.5212.0120.88833.9367.86101.8135.7169.6203.6237.5271.4305.3141.2145.6792.36138.6184.7230.9277.1323.2369.5415.6161.5860.32120.7181.0241.2301.5361.9422.2482.5542.9182.0076.34152.7229.1305.3381.7458.0534.4610.7687.1202.4794.24188.5282.8377.0471.2565.4659.7753.9848.2222.98114.0228.1342.1456.2570.2684.2798.3894.81027253.85147.3294.5441.8588.9736.3883.5103111781326284.84172.8345.6518.4691.2864.01036121013831555326.32225.7451.4677.1902.811281354158018062031368.00285.7571.3857.0114314281714199922852571409.87352.6705.31058141117632116246928213174钢筋规格HPB300理论重量Kg/m钢筋模数12345678940.09812.625.137.750.362.875.488.0100.5113.150.15419.639.358.978.598.2117.8137.4157.1176.760.22228.356.584.8113.1141.4169.6197.922625480.39550.3100.5150.820125130235240245290.563.6127.2190.9254318382445509573100.61778.5157.1236314393471550628707120.888113.12263394525656797929051018141.21153.9308462616770924107812321385161.5820140260380410051206140716081810182.00254509763101812721527178120362290202.47314628942125715711885219925132827222.983807601140152119012281266130413421253.854919821473196324542945343639274418284.8461612321847246330793695431049265542326.3280416082413321740214825563064347238368.00101820363054407250896107712581439161409.8712572513377050276283754087961005311310钢筋面积As（mm2）1m宽的钢筋面积As（mm2）钢筋间距（mm）理论重量Kg/m钢筋直径（mm）66/888/101010/121212/14148035349162880598211981414166919249031443655971687310651257148417101002833935036447859581131133515391102573574575857148711028121413991202363274195376547989421113128313021730238749560473787010271184140202280359460561684808954110015018826233542952463975489010261601772453144034915997078349621701662312963794625646657859061801572182793584365326287428551901492072653394135045957038102001411962513223934795656687702101351872393073744565396367332201291782282933574365146077002301231712192803414174925816692401181642092683273994715566412501131572012583143834525356161m宽的钢筋面积As（mm2）钢筋间距（mm）钢筋直径（mm）66/888/101010/121212/141414/161616/181818/202020/222222/25257040456171892011221369161619072199253628723254363540624488495954306221701275377524670859104712781508178020532367268130373393379141894629506858076545803534916288059821198141416691924221925132847318135543927433947525444616385333462591758924112713311571181120882365268029943345369640844472512457759031443655971687310651257148417101972223425312827315934913857422448395454952984135296788271009119014051620186821162398267929933307365440014584516710028339350364478595811311335153917752011227825452843314234713801435549091102573574575857148711028121413991614182820712313258528563156345639594462120236327419537654798942111312831479167618982121236926182893316836294091125226314402515628767905106812321420160818222036227525132777304134843927130217302387495604737870102711841365154717521957218724172670292433505776140202280359460561684808954110012681436162718182031224424802715311135061501
