万科钢筋工程施工标准化做法（一） 条形捆扎交货形式 圆盘交货形式 施工机具 场地布置合理，原材料与半成品分开堆放 材料标识牌，600mm*450mm 长条钢筋采用塔吊直接吊运，严禁单股钢丝绳吊运 箍筋采用料斗吊运，严禁装载超过料具上口 墙柱钢筋绑扎要求画线绑扎，水平（箍筋）钢筋间距满足设计要求，水平筋或箍筋与每根主筋相交位置绑扎到位，严禁跳绑 钢筋在浇筑混凝土前，用PVC管保护主筋不受污染 距离浇筑板面500mm处加箍筋，固定柱主筋偏位 墙、柱钢筋直径≥20mm，采用机械接头 墙、柱钢筋直径＜20mm，采用电渣压力焊 柱核心区箍筋：加工焊接成如图所示钢筋笼，梁钢筋绑扎完成时一同下沉到预定位置；梁钢筋绑扎主筋间距分布均匀，箍筋绑扎到位（箍筋与每根主筋相交位置必须有效绑扎牢固） 梁主筋直径≥20mm，采用机械接头；梁主筋＜20mm采用焊接或绑扎搭接 主次梁交接处，主梁方向箍筋在交接位置按设计图纸间距绑扎 梁、柱箍筋按抗震要求，弯成135度角 梁钢筋一排筋与二排筋采用分隔筋隔开，分隔筋直径≥主筋直径或25mm；分隔筋距支座边500mm设置一道，中间每隔3m设置一道 板面筋在边支座锚固时，直接延伸到梁最外面一根钢筋的内侧弯下 板配筋采用双层双向+分离式配筋，取消分离式配筋形式（面筋推荐不小于Ф8，具体以设计为准） 面筋锚固端与梁箍筋（主筋）、墙主筋（水平筋）绑扎牢固，面筋绑扎要满绑 板底筋绑扎前，画线控制间距，建议采用弹线控制 板面筋采用满绑（纵横钢筋交接位置都必须进行绑扎），不得出现“隔一绑一”的跳绑形式 楼板上预留洞口≥500mm，封口处采用U型钢筋 板内阳角增加7根直径同板面筋的放射钢筋，长度不小于1700mm （未完待续，请继续关注） the principle of simplified EIA of construction projects in the region. In terms of land, linked to the implementation of urban and rural construction land increase and decrease, replacement indicators for priority areas project. Charges, into the projects of water, electricity, administrative charges and preferential policies. In the area of taxation, and settled in areas of industry and its production company, within 5 years after the completion of fiscal incentives to enterprises. In terms of financing, integration of land, tax, financial and other resources, and construct Government credit + business credit credit system, establishment of marketization, commercialization and modernization of the investment and financing platform; effective Bank-enterprise docking, encourages private capital into the Park, to raise industry development fund. 5, optimize the environment and service industries. To create policy lowlands, Highlands, integrity of service land, development land as the goal, to optimize the area under development environment.
