alt="抗震支架能抵御地震作用力" src="http://www.ruimingdaxia.cn/uploads/allimg/200711/1-200G115010NC.jpg" style="width: 500px; height: 332px;" /></div> <div> </div> <div> 那么抗震支吊架是如何抵御地震作用力，避免機電設施掉落損壞的呢？我們從以下這幾個方面簡單了解。</div> <div> </div> <div> 1、抗震支架為什么能抵御地震作用力？</div> <div> </div> <div> 地震是地殼釋放能量的過程中造成的振動，通過地震波對人類的生活造成影響甚至破壞。</div> <div> </div> <div> 地震波可以分為縱波（P波）、橫波（S波）、和面波（L波）三種形式：</div> <div> </div> <div> 縱波屬于推進波，使地面發生上下的震動，破壞性相對較弱；</div> <div> </div> <div> 橫波屬于剪切波，使地面發生前后左右的抖動，破壞性較強；</div> <div> </div> <div> 面波屬于縱波和橫波在地表相遇后激發產生的混合波，破壞性最強。</div> <div> </div> <div> 重力支吊架雖可起到抵抗、緩解垂直地震力（即縱波）的作用，但抗震支吊架，通過其獨特的斜撐結構，大大的抵抗和緩解水平地震力（即橫波）的作用。</div> <div> </div> <div> 2、抗震支吊架的抗震斜撐有什么作用？</div> <div> </div> <div> 上面我們說到抗震支吊架是通過抗震斜撐的加固，來起到抗震的作用?？拐鹦睋蔚拇嬖?，使得本來在水平方向上毫無束縛的管道支吊架系統能夠在地震發生時做到安全可靠，防止管道支吊架系統垮塌掉落，造成嚴重的次生災害。</div> <div> </div> <div> 我們可以通過簡單的圖片來理解：</div> <div> </div> <div> <img alt="抗震支吊架的抗震斜撐作用" src="http://www.ruimingdaxia.cn/uploads/allimg/200711/1-200G11503235U.jpg" style="width: 447px; height: 321px;" /></div> <div> </div> <div> 應用到實際中來，抗震斜撐起到“抗震”的功能，也是按照上述原理。假如未設置抗震斜撐，請參考下圖效果：</div> <div> </div> <div> <img alt="未設置抗震斜撐參考效果圖" src="http://www.ruimingdaxia.cn/uploads/allimg/200711/1-200G115040HZ.gif" style="width: 395px; height: 222px;" /></div> <div> </div> <div> 3、斜撐與承載重力有否關系？</div> <div> </div> <div> 由第2點我們可以知道，抗震斜撐在力學上，有一定的重力荷載效應。當然，管道支吊架系統所承載的重力越大，抗震斜撐上承受的重力效應值也越大，所以斜撐的抗震作用與承載重力確實存在一定的關系。</div> <div> </div> <div> 但是，有一點我們需要注意，抗震支吊架的功能性主要是“抗震”，而非“承載”?？拐鹬У跫馨惭b的前提是，重力支吊架必須符合條件，能夠滿足垂直方向上所有管道及介質等因素的重力作用，即不考慮抗震支吊架上的重力作用也能滿足功能需求。通俗的說，可以概括成：抗震斜撐上有重力作用，但是我們在進行設計和計算時，暫不考慮抗震支吊架的重力效應，即不考慮重力共架。（特例除外，某些空間狹小的地方可能會出現重力共架的情況。）</div> <div> </div> <div> 4、抗震連接件的功能性分析</div> <div> </div> <div> 抗震連接件一般有如下幾種形式：</div> <div> </div> <div> <img alt="抗震連接件" src="http://www.ruimingdaxia.cn/uploads/allimg/200711/1-200G115051b36.jpg" style="width: 509px; height: 753px;" /><br /> <img alt="抗震連接件" src="http://www.ruimingdaxia.cn/uploads/allimg/200711/1-200G1150600X5.jpg" style="width: 500px; height: 344px;" /></div> <div> </div> <div> 由以上我們可以知道，抗震連接構件基本都是采用鉸鏈形式，在地震發生時，提供一個類似緩沖的功能，避免純剛性的連接可能會造成的拉斷。</div> <div> </div> <div> 抗震連接構件與混凝土建筑結構連接的地方，一般采用后擴底錨栓，這類錨栓具備很好的錨固作用，比常規的膨脹螺栓連接強度更高。</div> <div> </div> <div> 建筑機電抗震系統的組成包括立管管束、鋼梁及檁條夾鉗、環狀管吊、防震斜撐系統、防震鋼吊件與支撐等等。</div> </div> <div class="syp">上一篇：<a href='http://www.ruimingdaxia.cn/wt/104.html'>抗震支架的檢測都有哪些項目?</a> </div> <div class="syp">下一篇：<a
