一、施工流程:I. Construction process:
設備點件檢查→支架製作及安裝→封閉插接母線安裝→試運行驗收Equipment inspection → support production and installation → closed plug bus installation → test run acceptance
二、設備點件檢查:Two, equipment inspection:
1、設備開箱點件檢查,應有安裝單位、建設單位或供貨單位共同進行,並做好記錄。1. Equipment unpacking inspection should be carried out by the installation unit, the construction unit or the supplier together, and the record should be made.
2、根據裝箱單檢查設備及附件,其規格、數量、品種應符合設計要求。2. Check the equipment and accessories according to the packing list, and the specifications, quantity and varieties shall meet the design requirements.
3、檢查設備及附件,分段標誌應清晰齊全、外觀無損傷變形,母線絕緣電阻符合設計要求。3, check the equipment and accessories, the section mark should be clear and complete, the appearance of no damage deformation, bus insulation resistance in line with the design requirements.
4、檢查發現設備及附件不符合設計和品質要求時,必須進行妥善處理,經過設計認可後再進行安裝。4, the inspection found that the equipment and accessories do not meet the design and quality requirements, must be properly handled, after the design approval before installation.
三、支架製作及安裝:Three, bracket production and installation:
支架製作和安裝應按設計和產品技術檔的規定製作和安裝,如設計和產品技術檔無規定時,按下列要求製作和安裝。The manufacture and installation of the support shall be made and installed according to the provisions of the design and product technical documents. If there is no stipulation in the design and product technical documents, the manufacture and installation shall be made and installed according to the following requirements.
1、支架製作:1. Support production:
(1)根據施工現場結構類型,支架應採用角鋼或槽鋼製作。應採用“一”字型、“1”型、“U”字型、“T”字型四種型式。(1) According to the construction site structure type, the support should be made of Angle steel or channel steel. The four types should be "one" type, "one" type, "U" type and "T" type.
(2)支架的加工製作按選好的型號,測量好的尺寸斷料製作,斷料嚴禁氣焊切割,加工尺寸大誤差5mm。(2) The processing of the support is made according to the selected model and the measured size of the material cutting. The material cutting is strictly prohibited by gas welding and cutting, and the processing size has a large error of 5mm.
(3)型鋼架的煨彎宜使用臺鉗用鎯頭打制,也可使用油壓煨彎器用模具頂制。(3) The bending of the section steel frame should be made by using a vise with head, or using an oil pressure bending mould
(4)支架上鑽孔應用台鑽或手電筒鑽鑽孔,不得用氣焊割孔,孔徑不得大於固定螺栓直徑2mm。(4) Bench drill or hand electric drill shall be used to drill holes on the support, and gas welding shall not be used to cut holes, and the aperture shall not be greater than the diameter of the fixed bolt by 2mm.
(5)螺杆套扣,應用套絲機或套絲板加工,不許斷絲。(5) screw sleeve buckle, the application of the wire machine or wire plate processing, do not break the wire.
2、支架的安裝:2, bracket installation:
(1)封閉插接母線的另彎處以及與箱(盤)連接處必須加支架。直段插生產建設母線支架的距離不應大於2m。(1) The other bend of the closed plug in bus and the connection with the box (disk) must be supported. The distance of bus support in the production and construction of straight segment insertion shall not be greater than 2m.
(2)埋注支架用水泥砂漿,灰砂比1∶3。425號及其以上水泥,應注灰飽滿、嚴實、不高出牆面,埋深不少於80mm。(2) Cement mortar for buried support, cement-sand ratio of 1∶3. No. 425 and above cement, should be filled with ash, strict, not higher than the wall, buried not less than 80mm.
(3)膨脹螺栓固定支架不少於兩條。一個吊架應用兩根吊杆,固定牢固,螺扣外露2~4扣,膨脹螺栓應加平墊和彈簧墊,吊架應用雙螺母夾緊。(3)At least two supports for fixing expansion bolts. One hanger should use two hanger rods, fixed firmly, screw buckle exposed 2 ~ 4 buckle, expansion bolt should be added flat washer and spring washer, hanger should be clamps with double nuts.
(4)支架及支架與埋件焊接處刷防腐油漆應均勻,無漏刷,不污染建築物。(4) Bracket and bracket and embedded welding brush anti-corrosion paint should be uniform, no brush leakage, do not pollute the building.
四、封閉式母線的安裝:Four, the installation of the enclosed bus:
封閉式母線施工要求高,工程量較大,所以在施工工程中要嚴格遵守施工品質規範要求,保證施工品質。The construction requirements of closed busbar are high and the amount of work is large, so the construction quality specifications should be strictly observed in the construction project to ensure the construction quality.
1、一般要求:1. General requirements:
(1)封閉插接母線應按設計和產品技術檔規定進行組裝,組裝前應對每段進行絕緣電阻的測定,測量結果應符合設計要求,並做好記錄。(1) The closed plug in bus shall be assembled in accordance with the design and product technical documents. Before assembly, the insulation resistance of each section shall be measured. The measurement results shall meet the design requirements and be well recorded.
(2)匯流排,固定距離不得大於2.5m。水準敷設距地高度不應小於2.2m。(2) The fixed distance of busbar shall not be more than 2.5m. The horizontal laying distance should not be less than 2.2m.
