在日常的生活中我們經(jīng)??梢砸姷缴綎|電纜橋架,它的出現(xiàn)給我們帶來了很大的方便,但在生產(chǎn)完之后是有一些部件安裝以及保管事項(xiàng)需要我們?nèi)プ⒁獾模敲吹降资窃鯓拥哪??接下來讓我們的工作人員來給大家簡單介紹一下其相關(guān)知識(shí)點(diǎn)。
In our daily life, we can often see Shandong cable tray. Its appearance has brought us great convenience. However, after production, we need to pay attention to the installation and storage of some parts. So what exactly is it? Next, let our staff give you a brief introduction to their relevant knowledge points.
電纜橋架部件安裝的注意事項(xiàng):
Precautions for installation of cable tray components:
1、吊架安裝:采用通絲螺桿雙桿式吊架安裝方式。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。通絲吊桿要根據(jù)橋架的寬度來選擇,見下: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(shí),需要考慮防震要求的地方,使用減震支架。平面橋架安裝時(shí)近量往上抬,少應(yīng)滿足底距吊頂50mm。
1. Hanger installation: adopt threaded screw double rod hanger installation method. The support of horizontal bridge adopts galvanized threaded rod as suspender and galvanized angle steel as cross arm. The spacing between supports is 2m. The support shall be set at the corner of the bridge. The support shall be fixed under the floor with expansion bolts. The wire hanger shall be selected according to the width of the cable tray, as shown below: the vertical cable tray support shall be made of section steel, and the fastener shall be matched with the cable tray. The support shall be fixed on the wall or floor and fixed with expansion bolts. When the vertical cable tray passes through the floor, the shock absorption support shall be used where the seismic requirements need to be considered. When installing the plane bridge, lift it up to at least 50mm from the bottom to the ceiling.
2、支、吊架的調(diào)整:橋架安裝中,對橋架的支、吊架位置誤差,應(yīng)嚴(yán)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(jìn)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。
2. Adjustment of supports and hangers: During the installation of bridge, the position error of supports and hangers of bridge shall be strictly controlled. The supports and hangers of cable tray shall be installed firmly, horizontally and vertically. The fixing method of supports and hangers shall be as required. The cross arms on 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 deviation of bridge supports and hangers from left to right along the bridge shall not be greater than 10mm/m.
3、橋架與各種管道的小凈距:橋架與一般工藝管道平行架設(shè)時(shí),間距不應(yīng)小于400mm;電纜橋架與熱力管道平行架設(shè)時(shí),其間距當(dāng)熱力管道有保溫層時(shí)不小于500mm,無保溫層時(shí),不應(yīng)小于1000mm。橋架與一般工藝管道交叉時(shí),凈距不應(yīng)小于300mm,橋架在管道下方安裝時(shí),應(yīng)使用隔熱板保護(hù)。電纜橋架不宜在熱力管道的上方平行安裝,當(dāng)無法避免需在熱力管道上方平行安裝時(shí),間距不應(yīng)小于1000mm,其間應(yīng)采取隔熱措施;電纜橋架與熱力管道交叉時(shí),當(dāng)熱力管道有保溫層時(shí),交叉距離不應(yīng)小于500mm,無保溫層時(shí),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(hù)起來,隔熱板長度不應(yīng)小于熱力管保溫層外徑加2000mm。
3. Small clear distance between cable tray and various pipes: when cable tray is erected in parallel with general process pipes, the distance shall not be less than 400mm; When the cable tray is erected in parallel with the thermal pipeline, the distance between them shall not be less than 500mm when the thermal pipeline has thermal insulation layer, and not less than 1000mm when there is no thermal insulation layer. When the cable tray crosses the general process pipe, the clear distance shall not be less than 300mm. When the cable tray is installed under the pipe, it shall be protected by heat insulation board. The cable tray should not be installed in parallel above the thermal pipeline. When it is unavoidable to install it in parallel above the thermal pipeline, the spacing should not be less than 1000mm, and thermal insulation measures should be taken between them; When the cable tray crosses the thermal pipeline, the crossing distance shall not be less than 500mm when the thermal pipeline has thermal insulation layer, and 1000mm when there is no thermal insulation layer. The cable tray shall be protected by heat insulation board (such as asbestos board) at the intersection. The length of the heat insulation board shall not be less than the outer diameter of the thermal pipeline insulation layer plus 2000mm.
橋架的保管:橋架暫時(shí)不能安裝時(shí),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(dāng)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(shí)處理后再存放。
Storage of cable tray: When the cable tray cannot be installed temporarily, its storage place should be dry, covered, well ventilated, and protected from corrosive substances such as acid, alkali and salt. In the storage place, it must be classified and stacked, and shall not be knocked. The layers shall be separated with appropriate soft cushion to avoid high pressure, so as to prevent deformation and damage of anti-corrosion coating, which will affect the construction and bridge quality. In the corrosive environment, there should also be anti-corrosion measures. Once deformation and anti-corrosion coating damage are found, they should be handled in time before storage.
