style="text-indent:25px">鋼結(jié)構(gòu)是連接樓頂與軌道的承重結(jié)構(gòu)，鋼結(jié)構(gòu)涉及到整個活動隔斷系統(tǒng)的安全性，所以決不能掉以輕心。按照施工圖在樓頂打拉爆螺絲，然后把角鐵焊接固定。按設計要求選擇軌道固定件。安裝軌道前要考慮墻面、地面、頂棚的收口做法并方便活動隔墻的安裝。安裝軌道：⑴懸吊式軌道:懸吊導向的固定方式是在隔扇頂面安裝滑輪，并與上部懸吊的軌道相連。軌道、滑輪應根據(jù)承載重量的大小選用。輕型活動隔斷墻，軌道用木螺釘或?qū)Q螺釘固定在沿頂木框或鋼框上。重型活動隔墻，軌道用對擰螺釘或焊接固定在型鋼骨架上。⑵支承式軌道:支承導向的固定方式是滑輪在隔板下部，與地面軌道構(gòu)成下部支承點。軌道用脹栓或與軌道預埋件固定，并在沿頂木框上安裝導向軌。⑶安裝軌道時應根據(jù)軌道的具體情況，提前安裝好滑輪或軌道預留開口(一般在靠墻邊1/2隔扇)</p><p style="text-indent:25px">鋼軌與軌枕間的聯(lián)結(jié)是通過中間聯(lián)結(jié)零件實現(xiàn)的。中間聯(lián)結(jié)零件也稱扣件，要求具有足夠的強度、耐久性和一定的彈性，以便長期有效地保持鋼軌與軌枕的可靠聯(lián)結(jié)，阻止鋼軌相對于軌枕的移動，并能在動力作用下充分發(fā)揮其緩沖減震性能，延緩軌道殘余變形的積累。由于火車的車身很笨重，如果火車輪子直接在石子路或水泥路上行駛，就會使路面產(chǎn)生下陷的現(xiàn)象，用了鋼軌和枕木等，就能降低沉重的火車對地基的壓強。而且，鐵路的兩條鋼軌之間有一定的距離，叫做軌距，它跟同軸的兩個有輪緣的火車輪的距離是相配合的。這樣，通過車輪與鋼軌的固定關(guān)系，火車就能順著兩條鋼軌的方向行駛了，這也是火車要在鋼軌上行駛的另一個原因。鋼軌的類型是以每米長的鋼軌質(zhì)量千克數(shù)表示的。</p><div

style="text-indent:25px">火車的載重量很大，而且隨著科技的發(fā)展，其載重量越來越大，這也就意味著鋼軌的承受能力要足夠大。鋼軌的承受能力除了和鋼軌的材質(zhì)有關(guān)以外，還和鋼軌的形狀有關(guān)。由于在同一種材質(zhì)下，受力面積越大，受到的壓力就越小，所以，鋼軌的頂面即軌頭需要有一定的寬度來承載火車的重量。因為面積較大，鋼軌的穩(wěn)定性就更好，所以鋼軌的底面即軌底也需要一定的寬度。加上，火車的車輪邊緣有一定的高度，為了適應這種高度，鋼軌也必須有一定的高度。于是,鋼車織成了工字形。鋼軌是鐵路軌道的主要組成部件，它在于引導機車車輛的車輪前進，承受車輪的巨大壓力，并傳遞到軌枕上。南京標準滑軌鋼</p><p style="text-indent:25px">減緩鋼軌接觸疲勞傷損的措施有：凈化軌鋼，控制雜物的形態(tài)。無錫冷軋軌鋼</p><p style="text-indent:25px">鋼軌的打磨需要對接頭和絕緣接頭軌端肥邊，應及時整修處理。固定型轍叉及可動心軌頂面不平順，尖軌、固定型轍叉、可動心軌、翼軌工作邊及尖軌非工作邊出現(xiàn)肥邊，應打磨整修。鋼軌上打眼注意事項：打軌腰處，打多個的話，距離別太小，不可過密?；乇芎缚p和鋼軌軌道電路的螺栓孔和電線。鋼軌的高強螺栓安裝注意事項：1.當天安裝的高強螺栓，當天終擰完畢；2.螺栓穿入方向以方便施工為準，每個節(jié)點整齊一致；3.高強螺栓超擰時應更換，并不得重復使用；4.安裝中的錯孔、漏孔不得用氣割開孔，錯孔補焊后砂輪打磨，重新鉆孔；5.螺栓、螺母及墊圈應放在**工具袋內(nèi)，嚴防高空墜落；6.安裝用螺栓不得用高強螺栓代替。無錫冷軋軌鋼</p></p><br
