      结构工程师告诉你飘窗为什么不能轻易砸！！

      发布于：2021-05-18 08:40:18 来自：建筑结构/混凝土结构 [复制转发]

      小编自从开始关注装修之后，潜伏在各种群里的我经常看见业主想要 “砸飘窗”。小编每回看见都要杀进去苦口婆心地说明现在的商品房不能轻易砸飘窗。然而“砸飘窗”这个话题几乎每个月都会被重提一次。仿佛在很多人的意识中，飘窗区域就是开发商赠送的面积，它的存在就是用来砸掉扩充面积的。基于此，小编不得不以结构工程师的角度专门送上一篇文章，告诉大家，飘窗真的不能随意砸！！



      可能在大家的眼中，飘窗是电视剧里女主角用来坐在窗边边喝红酒听音乐边望着窗外灯火阑珊的城市发呆的载体，又或是清晨傍晚阳光射进房间时主人公坐着看书喝茶的地方，总之一切都是那么悠闲又充满了诗意。



      但因为现在城市的高房价，再加上目前流行的户型设计风格倾向于客厅面积大，卧室面积小，很多业主装修时都想充分利用自己家中的每一寸空间。可并不是所有的飘窗都是可以随意砸掉的，如果乱砸可能会后患无穷，遗憾终身。下面小编就跟大家好好聊一聊关于飘窗的事宜。



      先来聊一聊什么是飘窗？


      飘窗是舶来品，起源于英国维多利亚时期，它是建筑本身的凸形结构。现在，中国的商品房中飘窗一般呈矩形或梯形向室外凸起，一面或者三面都装有玻璃。飘窗有 内飘 和 外飘 两种类型，外飘是凸的，内飘是平凹的。


      外飘窗 一般三面都是玻璃窗，凸出墙体，底下是凌空的；

      内飘窗 一般都有一面玻璃，两面是墙，比较安全，但是会占用室内的空间。


      飘窗能让房间看上去比实际大。这个非常好理解，外凸的飘窗能让房间看上去大一圈，视线被不自觉得延伸。

      根据规范，空间高度（从飘窗台到天花板的距离）低于2.2m的飘窗一般不计入建筑面积。因此，飘窗处的面积也不计入总房款，是附赠空间，这对于居住者来说当然是好事，相当于白白赚了好几万。既然飘窗是赠送的，那么飘窗能不能砸了重新利用呢？


      如果你家是假飘窗，那么，也许可以砸！如果你家是真飘窗，那么，坚决不能砸！

      现在的商品房绝大部分都是外飘窗，只有遇到非常良心的开发商才会做个不算面积的内飘窗吧。



      为什么外飘窗不能砸呢？

      小编又要默默拿出自己收藏很久的飘窗小图片给大家讲解了。

      飘窗有三种类型（如下图所示）：

      A-A剖面


      第一种：飘窗的台面是用砖砌起来的，就是在楼面处飘窗最外侧有一根梁。这种飘窗俗称内飘窗（假飘窗），砸掉确实是没有什么安全隐患。

      A-A剖面


      第二种：飘窗的台面是从飘窗起始部位上翻混凝土墩，然后挑板形成的，这种飘窗称之为外飘窗（真飘窗），根据立面的造型，有可能你砸掉这个飘窗后，飘窗下就直接漏了，直接通向通户外，有可能也是一个密闭的空间，砸掉这种飘窗，对结构有影响，也会影响建筑外立面、防水，另外还有窗户掉落的危险。

      A-A剖面


      第三种：飘窗的台面板是直接从飘窗起始处上翻梁挑出去的，这种飘窗外飘窗（真飘窗），砸掉最危险。这种飘窗要砸掉，就势必会砸掉那根上翻梁，为什么结构设计要做成上翻？那是因为这跟梁是连梁，由于剪跨比很小（窗户窄，两边就是剪力墙）导致这根梁剪力很大，必须要做很高才行，梁高了但是又不能漏到下楼，所以只能上翻。


      而且这样的上翻梁一般所配的钢筋都是直径较大的梁纵筋。砸断这根上翻梁，那绝对是要对主体结构安全产生很大影响的。不要命只要空间和美观的朋友就尽管砸吧，物业发现这个问题绝对会要求停工并做加固恢复原样的，房管局查到了还会重罚的！因为你影响到了整栋楼的安全，如果一旦拆除，很有可能就会造成楼板开裂、房屋坍塌，后果不堪设想。



      另外，现在很多商品房（尤其是上海）都对房屋的装配率有一定的要求，所以很多结构的外墙做了预制墙体。这样飘窗位置的梁不仅要承担自己飘窗板的重量，还需要承担几吨重的实心混凝土外墙重量。假设梁钢筋被砸断，预制墙体砸下来，画面将非常惨烈。



      “一锤子下去钢筋混凝土，再一锤子下去楼板连着空气，三锤子下去楼很可能都会塌了”。真的不是在和你开玩笑！如果砸了相当于给你家戳个洞，毁的不是一间房，分分钟毁掉一栋楼。



      所以，对于“砸飘窗”，我们一定要慎重下手，最好是根据现有的图纸去合理利用飘窗。能拥有一个温馨可爱的小家，不是很好嘛。

        现在好多都是真飘窗了，对于假飘窗 扩展室内面积的砌砖而成的，可以拆掉
