常用橋架有鋼制橋架、玻璃鋼橋架、鋁合金橋架和組合式橋架4類。下面山東電纜橋架廠家來進行說明。

Common cable tray includes steel cable tray, glass fiber reinforced plastic cable tray, aluminum alloy cable tray and combined cable tray. The cable tray manufacturer in Shandong Province will give instructions below.

(1)鋼制橋架、玻璃鋼橋架、鋁合金橋架安裝，又分別有槽式橋架、梯式橋架和托盤式橋架3種，均區分橋架規格(寬+高)，以“10m”為計量單位，不扣除彎頭、三通、四通等所占長度。其中橋架、蓋板和隔板的主材費另計。

(1) The steel cable tray, glass fiber reinforced plastic cable tray and aluminum alloy cable tray are installed, and there are three types of cable tray: slot cable tray, ladder cable tray and tray cable tray. The cable tray specifications (width+height) are distinguished. The unit of measurement is "10m", and the length of elbows, tees and crosses is not deducted. The cost of main materials for cable tray, cover plate and diaphragm shall be calculated separately.

另外注意：

Also note:

①不銹鋼橋架按本章鋼制橋架定額乘以系數1.1計算。

① The stainless steel cable tray shall be calculated by multiplying the steel cable tray quota in this chapter by the factor 1.1.

②鋼制橋架主結構設計厚度大于3mm時，定額人工、機械乘以系數1.2。

② When the design thickness of the main structure of the steel bridge is greater than 3mm, the quota labor and machinery shall be multiplied by a factor of 1.2.

③玻璃鋼梯式橋架和鋁合金梯式橋架定額均按不帶蓋考慮，如這兩種橋架帶蓋板，則分別執行玻璃鋼槽式橋架和鋁合金槽式橋架項目的定額。

③ The norms of glass fiber reinforced plastic ladder type cable tray and aluminum alloy ladder type cable tray shall be considered without cover. If these two types of cable tray have cover plates, the norms of glass fiber reinforced plastic channel type cable tray and aluminum alloy channel type cable tray shall be implemented respectively.

(2)組合式橋架以每片長度2m為一個基型片，需要在施工現場將基型片進行組合成橋架，以“100片”為計量單位計算，主材費另計。

(2) The length of each piece of composite bridge is 2m as a base piece. The base pieces need to be combined into a bridge at the construction site. The unit of measurement is "100 pieces", and the cost of main materials is calculated separately.

(3)組合式橋架支撐架以“100kg”為計量單位。適用于立柱、托臂及其他各種支撐架的安裝。本定額已綜合考慮了采用螺栓、焊接和膨脹螺栓3種固定方式，實際施工中，不論采用何種固定方式，定額均不做調整。

(3) The unit of measurement for combined bridge support is "100kg". It is applicable to the installation of columns, corbels and other supporting frames. This norm has comprehensively considered the use of bolts, welding and expansion bolts. In actual construction, no matter what kind of fixing method is used, the norm will not be adjusted.

(4)橋架、托臂、立柱、隔板、蓋板為外購件成品，連接用螺栓和連接件隨橋架成套購買，計算質量可按橋架總重的7%計算。

(4) The cable tray, corbel, column, diaphragm and cover plate are purchased finished products. The connecting bolts and connectors are purchased with the cable tray in a complete set. The calculated mass can be calculated as 7% of the total weight of the cable tray.
