電纜橋架擺放不好會導(dǎo)致電纜扭曲變形、霉變、脫膠、油漆暴裂,或者鼓泡、退色,今天給大家介紹一下有關(guān)
山東橋架的保管與部件安裝事項。
Improper placement of the cable tray will lead to distortion, mildew, degumming, paint cracking, blistering and discoloration of the cable. Today, I would like to introduce the storage and component installation of Shandong cable tray.
橋架的保管
Storage of bridge
橋架暫時不能安裝時,其貯存場所宜干燥、有遮蓋、有良好的通風(fēng)環(huán)境,應(yīng)避免酸、堿、鹽等腐蝕性物質(zhì)的侵蝕。在保存場所一定要分類碼放,不得摔打,層間應(yīng)用適當軟墊物隔開,避免高壓,以防變形和防腐層損壞,影響施工和橋架質(zhì)量。在有腐蝕的環(huán)境,還應(yīng)有防腐蝕的措施,一經(jīng)發(fā)現(xiàn)有變形和防腐層損壞,應(yīng)及時處理后再存放。
When the bridge cannot be installed temporarily, the storage place should be dry, covered and well ventilated, and the corrosion of acid, alkali, salt and other corrosive substances should be avoided. In the storage place, it must be stacked by classification, and it is not allowed to fall. The layers shall be separated by appropriate soft cushions to avoid high pressure, so as to prevent deformation and damage of anti-corrosion coating, which will affect the construction and bridge quality. In corrosive environment, anti-corrosion measures shall also be taken. Once deformation and damage of anti-corrosion coating are found, they shall be treated in time before storage.
橋架吊架安裝
Installation of bridge hanger
采用通絲螺桿雙桿式吊架安裝方式。
The installation method of through screw double rod hanger is adopted.
水平橋架支架采用鍍鋅通絲螺桿作吊桿,鍍鋅角鋼作橫擔(dān),支架間距按2m設(shè)置,在橋架的轉(zhuǎn)角處要設(shè)置支架,支架采用膨脹螺栓在樓板下固定。
The horizontal bridge support adopts galvanized through wire screw as suspender and galvanized angle steel as cross arm. The support spacing is set at 2m. The support shall be set at the corner of the bridge. The support shall be fixed under the floor with expansion bolts.
通絲吊桿要根據(jù)橋架的寬度來選擇,見下:
The through wire suspender shall be selected according to the width of the bridge, as shown below:
豎向橋架支架采用型鋼制作,固定件要與橋架配套。支架固定在墻體或樓板上,采用膨脹螺栓固定。豎向橋架穿樓板時,需要考慮防震要求的地方,使用減震支架。平面橋架安裝時近量往上抬,少應(yīng)滿足底距吊頂50mm。
The vertical bridge support shall be made of profile steel, and the fixings shall be matched with the bridge. The support is fixed on the wall or floor and fixed with expansion bolts. When the vertical bridge passes through the floor, the shock-absorbing support shall be used where the anti vibration requirements need to be considered. When the plane bridge is installed, the distance between the bottom and the ceiling shall be at least 50mm.

橋架支、吊架的調(diào)整
Adjustment of bridge supports and hangers
橋架安裝中,對橋架的支、吊架位置誤差,應(yīng)嚴格控制。電纜橋架支、吊架應(yīng)安裝牢固,橫平豎直。支、吊架的固定方式應(yīng)按要求進行。各支、吊架的同層橫擔(dān)應(yīng)在同一水平面上,其高低偏差不應(yīng)大于5mm/m;橋架支、吊架沿橋架走向左右的偏差不應(yīng)大于10mm/m。
During the installation of the bridge, the position error of the supports and hangers of the bridge shall be strictly controlled. The supports and hangers of cable tray shall be installed firmly, horizontally and vertically. Support and hanger shall be fixed as required. The cross arms of the same layer of each support and hanger shall be on the same horizontal plane, and the height deviation shall not be greater than 5mm / M; The left and right deviation of bridge supports and hangers along the bridge direction shall not be greater than 10mm / m.
橋架與各種管道的小凈距
Small clear distance between bridge and various pipes
橋架與一般工藝管道平行架設(shè)時,間距不應(yīng)小于400mm;電纜橋架與熱力管道平行架設(shè)時,其間距當熱力管道有保溫層時不小于500mm,無保溫層時,不應(yīng)小于1000mm。
When the bridge is erected in parallel with the general process pipeline, the spacing shall not be less than 400mm; When the cable tray is erected in parallel with the heat pipe, the distance between the cable tray and the heat pipe shall not be less than 500mm if the heat pipe has an insulation layer, and not less than 1000mm if there is no insulation layer.
橋架與一般工藝管道交叉時,凈距不應(yīng)小于300mm,橋架在管道下方安裝時,應(yīng)使用隔熱板保護。電纜橋架不宜在熱力管道的上方平行安裝,當無法避免需在熱力管道上方平行安裝時,間距不應(yīng)小于1000mm,其間應(yīng)采取有效的隔熱措施;電纜橋架與熱力管道交叉時,當熱力管道有保溫層時,交叉距離不應(yīng)小于500mm,無保溫層時,交叉距離不應(yīng)小于1000mm,且有交叉處應(yīng)用隔熱板(例如石棉板)將電纜橋架保護起來,隔熱板長度不應(yīng)小于熱力管保溫層外徑加2000mm。
When the bridge crosses with the general process pipeline, the clear distance shall not be less than 300mm. When the bridge is installed under the pipeline, it shall be protected with heat insulation board. The cable tray shall not be installed in parallel above the heat pipe. When it is unavoidable to install in parallel above the heat pipe, the spacing shall not be less than 1000mm, and effective thermal insulation measures shall be taken; When the cable tray crosses with the heat pipe, the crossing distance shall not be less than 500mm when the heat pipe has an insulation layer; when there is no insulation layer, the crossing distance shall not be less than 1000mm, and the cable tray shall be protected with a heat insulation plate (such as asbestos plate) at the intersection. The length of the heat insulation plate shall not be less than the outer diameter of the heat pipe insulation layer plus 2000mm.
此外橋架施工前需對綜合管線進行優(yōu)化排布,保持合理間距,減少翻彎、碰撞等,有條件的可以使用技術(shù)進行優(yōu)化調(diào)整。很重要,有事來網(wǎng)站

In addition, before the bridge construction, it is necessary to optimize the layout of the comprehensive pipelines, maintain a reasonable spacing, reduce bending and collision, etc. if conditions permit, technology can be used for optimization and adjustment. Safety is very important. Come to the website if you have something to do http://m.ymmgjx.net Consult!
