【文章內容簡介】 tween these two hanging bracket. 對于安裝在鋼結構上的支架，直接用卡扣卡在鋼結構上，用螺栓緊固，不得焊接；Support installed in the steel structure will be used clamp and bolt to install not allow to welding. 吊頂安裝在樓面的支架，先標出需要打眼部位，用沖擊電錘鉆出合適的孔洞，通過內膨脹螺栓固定預制好的支架；If bracket need to install in the structure ceiling, firstly draw hole position and make hole with electric punch hammer drill, then bracket be fixed by expansion bolt. 橋架預制Cable tray prefabrication 橋架預制都在預制場地進行，預制橋架過程中，只允許用切割機進行切割，嚴禁用電焊、氣焊切割，切割完后清楚毛刺并打磨光滑；the cable tray will be prefabricated in the prefabrication shop. abrasive cutting machine will be used to cut prefabricated cable tray and it is forbidden using welding machine to cut. after finishing cutting, removing burrs and make it smooth. Galvanized lacquer will be sprayed in the processed part of cable tray.對于鍍鋅橋架,應在預制處噴涂鍍鋅漆； 不準用電焊直接把兩段橋架焊在一起；It is forbidden to connect two cable tray with welding method. 橋架安裝Installation for cable tray 橋架安裝前應盡量在地面進行預組裝；對于管廊處大跨距橋架，直接在支架上安裝；The cable tray will be assembled in the floor as best as we can before installation. 在地面預組裝完后，將橋架架上托臂，把橋架調整水平，然后用壓板固定；After finishing assemble, cable tray will be put on the bracket arm, then make leveling and fixed by clamping plate. 橋架固定應牢固，連接無錯邊，連接板螺栓應緊固且螺母應位于橋架槽的外側,螺帽應安裝在內側。The cable tray will be firmly fixed, there is no change in the connection joint。 bolt will be tighten in the connection plate and nut will be outside in the cable tray, head of bolt will be inside in the cable tray. 連接螺栓前應在螺栓上噴上防卡劑；Before connecting bolt, anti block agent will be sprayed in the bolt. 同一水平面橋架水平度要一致、無變形，多層橋架間距應保持一致；The horizontality should be the same in the same horizontal and no deformation。 The distance of cable tray between layer should keep the same. 橋架穿越樓板洞、墻洞，應用防火膠泥密封；Cable tray through floor hole and wall hole,fire proof clay will be used to seal hole after cable to be laid. 橋架接地線敷設Laying earthling wire of cable tray. 橋架安裝完后，應對橋架做接地處理，After cable tray be installed, earthling of cable tray will be done according to technical requirement. see item ８、 施工注意事項及措施Construction precaution and measurement to be taken SPCII電纜橋架安裝大部分是在生產與施工的環境下同時進行，務必要求所有進入生產區域現場施工的人員不得接觸任何與施工無關的設備，并且嚴禁碰撞生產設備、管線，施工用的材料只能堆放在指定的場所，當日施工結束后，必須清掃干凈；In SPCII project, cable tray be installed is under production and operation environment in the same workshop, It is required that all construction people can not touch any irrespective equipment with construction and forbidden to hit any production equipment and pipe. The material using for construction only put appointed site. Work finished every day, construction site should be cleaned. 生產區域內介質都為有毒的液體、氣體或粉末狀物質，在建筑物內生產區域施工時，應設置警戒線，只能在規定的警戒線范圍內施工；從管廊進入B204區域橋架施工時，應在施工區域內搭設防護欄，并且派專人看管，施工時嚴禁動用電焊或氣焊；There are a lot of poisonous gas and liquid material in production area, guarding line will be set up in construction area of inside building. Construction only be made within stated guarding line. When cable tray be installed from outside pipe rack into B204 area, guard rail will be established in this construction area and should have person to be in charge. Welding will be prohibited in the construction. 在防爆區域內施工時，要求所有施工用電器設備都具有防爆功能，所用的臨時施工電源要求使用防爆插座，并配置防爆插頭；When construction made in the antidetonation area, It is required that all electrical appliance for construction should have explosion proof function and all temporary power should use explosion proof receptacle and plug. 在生產區域施工時，施工用電源線不能直接跟運行設備、管線接觸，應加工電纜掛鉤掛臨時電源線，掛鉤也不能掛在設備及管線上，并且掛鉤上應用塑料套管隔離。When construction made in the production area, power cable for temporary construction can not touch operation equipment and pipe. Leased clamp be used for hanging the temporary power cable and can not hang on the equipment and pipe. 在對有電纜在內的橋架開槽時，應把運行電纜隔離開，嚴禁損壞一期原有電纜，采取的防護措施如下：在需切割的部位事先放上C形狀的薄鐵板，然后用防火布覆蓋，并且在橋架下方鋪設一層防火布，再用砂輪切割機切割，切割后清除毛刺，并打磨光滑；When we need to make duct in the cable tray with living cable, cable with electricity will be unplugged and not allowed to damage existing cable, measure will be taken as follow: the places we need to cut should put a pieces of C type thin steel plate in advance, then cover a piece of fire proof cloth on the steel plate and put fire proof cloth under cable tray at the same time, then we can cut hole with abrasive cutting machine , after cutting, remove burry and make it smooth. 從B196至B204廠房間的橋架都位于室外管廊上，且屬于高空作業， 除了遵守相應的高空作業規定外，霧天、雨天應禁止在管廊上施工作業；Some installation from B196 to B204 in the outside pipe rack is aloft work, except following relevant regulation of aloft work, it should be prohibited in the rain and fog weather. 在生產區域施工時，禁止利用原有的電纜橋架、工藝管線或風道及設備來搭設跳板，嚴禁踩踏；It should be prohibited to use exist cable tray and pipe or ventilation duct to set up sleeper and to trample the equipment in the production area. 在生產區域動火作業時（包括用電錘、電鉆、磨光機等用電設備）必須有專人監護，且必須事先準備好消防器材； There are special people to supervise when hot work( including using electric hammer and drill as well as grater etc ) to be done in the production area, at the same time, firefighting apparatus will be prepared in advance. 在B19管梁上、B204生產區域內施工時必須開操作票，辦理工作許可證，無證嚴禁施工 Before job performed in the B196 area, outside pipe rack, B204 production area, operating sheet and permitting work certificate should be done, if no this kinds of certification, it is prohibited that not allowed to work in above area. 施工特別措施Special measurement to be taken in construction 在B196區G36～G37軸線安裝時，在+150橋架同原有預留橋架連接，通過管廊鋼梁做支架立柱，把C型鋼用卡扣固定在鋼梁上做橋架支架，. ，連接時需在橋架開槽，；在施工作業前，需搭設腳手架，腳手架操作平臺搭設區域見附圖1，樣式圖見附圖2；When we install cable tray at axis of G36G37 in B196 area, 900x150 cable tray will be connected to exist 900x150 cable tray at +, using clamp to fix C steel as bracket to the steel beam of pipe rack, then install vertical cable tray up to and put cable tray on bracket and connected to exist cable tray. When cable tray need to be connected to exist cable tray, somet
