電纜橋架安裝的平整度檢測需通過以下要點進行，確保安裝質(zhì)量符合規(guī)范要求：

　　The flatness inspection of cable tray installation should be carried out through the following points to ensure that the installation quality meets the specifications:

　　一、水平度檢測

　　1、 Levelness detection

　　整體水平度

　　Overall levelness

　　使用精度0.02mm/m的框式水平儀，沿橋架全長測量，每10m取3個測點，水平偏差平均值≤3mm/m（總偏差≤15mm/10m）。例如10m長橋架總偏差≤20mm。

　　Using a frame level with an accuracy of 0.02mm/m, measure along the entire length of the bridge, taking 3 measuring points every 10m, with an average horizontal deviation of ≤ 3mm/m (total deviation ≤ 15mm/10m). For example, the total deviation of a 10m long bridge is ≤ 20mm.

　　局部調(diào)整

　　partial adjustment

　　若局部偏差超標(biāo)，可在吊架與橋架間墊設(shè)0.5-2mm厚的薄鋼板微調(diào)，非常多不超過3層，調(diào)整后需用螺栓緊固。

　　If the local deviation exceeds the standard, a thin steel plate with a thickness of 0.5-2mm can be placed between the hanger and the bridge for fine adjustment, with a maximum of 3 layers. After adjustment, it needs to be fastened with bolts.

　　二、垂直度檢測

　　2、 Verticality detection

　　整體垂直度

　　Overall verticality

　　垂直橋架需用線錘或激光投線儀檢測，垂直偏差≤3mm/m（10m高橋架總偏差≤30mm），確保無傾斜。

　　Vertical cable trays need to be inspected with a plumb bob or laser wire projector, with a vertical deviation of ≤ 3mm/m (total deviation of 10m high bridge frame ≤ 30mm), to ensure no tilting.

　　橋架連接處加裝定位角鋼或?qū)蚣畛瑯?biāo)時需重新校準(zhǔn)或更換變形節(jié)段。

　　Install positioning angle steel or guide components at the connection of the bridge frame. If the deviation exceeds the standard, recalibration or replacement of the deformed section is required.

　　拼接處水平度

　　Levelness at the joint

　　橋架拼接時，用水平尺檢測拼接面水平度偏差≤2mm，縫隙需均勻（≤1mm），防止電纜卡頓或絕緣層磨損。

　　When splicing cable trays, use a level ruler to check the levelness deviation of the splicing surface, which should be ≤ 2mm, and the gap should be uniform (≤ 1mm) to prevent cable jamming or insulation layer wear.

　　三、驗收標(biāo)準(zhǔn)補充

　　3、 Supplementary acceptance criteria

　　外觀檢查

　　Visual inspection

　　目視檢查橋架表面是否平整光滑，無明顯劃痕、凹陷或樹脂脫落，顏色均勻。

　　Visually inspect the surface of the bridge for smoothness, no obvious scratches, dents, or resin peeling, and uniform color.

　　尺寸偏差

　　dimensional deviation

　　橋架與墻面/地面間距≥100mm，大跨度需加加強支撐。

　　The distance between the bridge and the wall/floor should be ≥ 100mm, and reinforcement support should be added for large spans.

　　連接件螺栓擰緊后外露絲扣≥2扣，防腐涂層無起皮、漏涂。

　　After tightening the connecting bolts, the exposed threads should be ≥ 2, and the anti-corrosion coating should not peel or be missed.

　　四、工具與方法

　　4、 Tools and Methods

　　水平儀 ：用于測量水平和垂直度，精度要求高。

　　Level gauge: used for measuring horizontal and vertical levels, with high precision requirements.

　　激光投線儀 ：輔助檢測垂直度，尤其適用于高精度場景。

　　Laser projector: assists in detecting verticality, especially suitable for high-precision scenes.

　　塞尺 ：檢測拼接縫隙寬度，確保≤0.5mm。

　　Feeler gauge: Check the width of the splicing gap to ensure it is ≤ 0.5mm.

　　通過以上檢測方法，可多維度評估電纜橋架安裝的平整度及整體質(zhì)量，確保符合GB50168等規(guī)范要求。

　　Through the above testing methods, the flatness and overall quality of cable tray installation can be comprehensively evaluated to ensure compliance with specifications such as GB50168.
