portant;">

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">1、基础梁接头位置不对，按楼层框架梁接头位置设置，且没有错开。基础梁与框架梁的受力正好相反，接头亦然。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">2、筏板钢筋接头在施工缝处预留长度不够，且接头没错开。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">3、基础马凳摆放错误，如果换一方向，每一排马凳可省一固定用通长钢筋。或者，马凳上通长钢筋利用筏板上部同方向纵筋。这条解释起来较困难，最好在现场演示。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">4、筏板面积较大，却仍按50%接头百分率，未按25%百分率接头，导致钢筋接头浪费。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">5、底板纵筋接头长度有的太长，超过一个搭接长度，有的则太短，不能满足规范所要求的长度。底板通长筋没绑扎成平行直线，导致同截面钢筋根数不同。这是施工技术和质量问题。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">6、筏板封边构造没按规范和设计，擅自设置筏板上下纵筋弯折长度。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">7、筏板纵筋接头不宜设置在后浇带位置。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">8、接桩钢筋并在一块。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); word-wrap: break-word !important;">

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">1、顶层中柱弯折，顶层中柱纵筋如果在梁内满足直锚就不需要弯折。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">2、柱梁节点箍筋未设置或间距太大。柱梁节点是核心节点，是抗震的关键节点。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">3、柱纵筋没有长短交错，这是钢筋翻样问题，对柱上下钢筋根数发生变化时没在下层调整竖向钢筋长度，导致接头未能错开。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">4、柱保护层未满足最小保护层厚度。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">5、有的暗柱很长，暗箍筋采用U型，增加钢筋接头，应该是封闭式箍筋，可节约钢筋。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">6、暗柱箍筋有内折角，这是下允许的。两个箍筋相交或锚固形成的角度不属于内折角。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">7、无地下室柱加密从正负零以上H0/3，应该是从基础顶面开始算起。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); word-wrap: break-word !important;">

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; word-wrap: break-word !important;">3

portant; display: -webkit-flex; margin: 0px; padding: 0px; max-width: 100%; width: 144.516px; justify-content: center; align-items: center; word-wrap: break-word !important;">

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; white-space: nowrap; word-wrap: break-word !important;">墙

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">1、墙水平筋（外侧与内铡）在同一位置搭接，没有按接头百分率错开接头。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">2、墙水平筋接头未设置在受力最小处。外墙外侧水平钢筋应位于跨中三分之一或墙高四分之一区域，外墙内侧应位于支座及支座附近。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">3、地下室外墙竖向钢筋接头位置错误，根据规范外墙外侧竖向钢筋应位于墙高中间的三分之一区域，外墙内侧竖向纵筋应位于墙高根部的四分之一区域。当然，这条规定本身是有问题的（从受力角度没有问题），缺少可操作性，无论如何是满足不了，属于规范脱离实际的无用条文。外墙可不采用插筋，一次性从基础到顶，不仅节约大量钢筋，而且，从受力角度也是最好的。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">4、外墙外侧钢筋顶模，无保护层，外墙外侧钢筋露筋后果很严重，最终把整个外墙破坏掉。外墙外侧是直接接触泥土和水，保护层不少于40mm。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">5、结构总说明未注明顶板是外墙的简支承还是弹性嵌固支承，施工也没按照按其施工，外墙纵筋弯折按墙厚减保护层，不知施工依据什么，还是想当然。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">6、墙纵向钢筋搭接长度过长，直接按墙高度。墙封顶时墙竖向钢筋应该是减去下面预留长度再加搭接长度。

portant; margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; font-family: 微软雅黑; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); text-align: justify; line-height: 2em; word-wrap: break-word !important;">7、墙拉筋绑扎不规范，要么间距不对，要么做法不对，如没拉住墙水平筋，要么拉筋长度不对，施工时不是垂直拉而是斜拉。
