style="text-indent:25px">橋架安裝選擇需屏蔽電氣干擾的電纜回路，有腐蝕的場所、易燃粉塵場所，應(yīng)選用無蓋無孔封閉型托盤，當(dāng)需要因地制宜的場所，宜選用組裝式托盤或有孔托盤及梯架；在容易積灰和其它需遮蓋的環(huán)境或戶外場所，宜帶有蓋板。低壓電力電纜與控制電纜共用同一托盤或梯架時，應(yīng)選用中間有隔板的托盤或梯架；在托盤、梯架分支、引上、引下處應(yīng)設(shè)適當(dāng)?shù)膹澩?；因受空間條件限制不便裝設(shè)彎通或有特殊要求時，可選用軟連接板，鉸接板；伸縮縫應(yīng)設(shè)置伸縮板；連接兩段不同寬度或高度的托盤、梯架可配置變寬或變高板。但在施工中，支、吊架和橋架的選擇應(yīng)依設(shè)計或工程布置條件選擇。</p><p style="text-indent:25px">從橋架側(cè)面取15cmX0.8在橋架底部畫點將這段距離等分,然后三個點連接就成一個45°的等腰三角形 (另一邊用同一方法)，然后將這個三角切掉就形成一個45°彎，然后再用要做的高度X1.41為**里邊的頂點再畫三角形，方向與前面那個相反，做出來就是一個45°之字彎。90°彎是取要做的那一面的2倍畫三角，例如400X150做水平彎頭,則取400X2畫三角切掉就行了，如果要做垂直彎頭則取150X2。橋架總結(jié)出來的公式：比如45度的坡度彎頭，你只要記住這句話就知道怎么做了“爬坡45 度，橋架高度乘以0.8中分劃三條線為一個彎，斜邊是爬坡高度乘以1.41 30度是橋架高度乘以0.8除以45乘以30中分劃三條線為一個彎，斜邊是爬坡高度乘以2 水平90度彎是橋架寬度乘以0.8中分劃線，斜邊(內(nèi)邊)600以上200乘以1.41 600以下100乘以1.41”。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">對于橋架的安裝需要注意：橫平豎直，彎頭處要平緩。當(dāng)橋架分層的時侯，比較好用組合架。橋架內(nèi)部要加設(shè)防火封堵或加設(shè)防火包。鋼制30米，鋁合金及塑料的15米要加伸縮節(jié)。過建筑物變形縫處（伸縮縫、沉降縫）加補(bǔ)償裝置。橋架的支架間距一般要求水平的為1.5 - 3米，垂直的為2米一個。螺母位于橋架的外側(cè)。當(dāng)支架與鋁合金橋架連接時，注意防電化措施。注意轉(zhuǎn)彎處支架的設(shè)置。配電室大型橋架要采用可調(diào)式組合支架大型工程橋架彎曲度要一致。樂山橋架哪家好</p><p style="text-indent:25px">樂山橋架哪家好</p><p
