常用桥架有钢制桥架、玻璃钢桥架、铝合金桥架和江南jn体育下载 4类。下面 山东电缆桥架厂家来进行说明。

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)钢制桥架、玻璃钢桥架、铝合金桥架安装，又分别有槽式桥架、梯式桥架和托盘式桥架3种，均区分桥架规格(宽+高)，以“10m”为计量单位，不扣除弯头、三通、四通等所占长度。其中桥架、盖板和隔板的主材费另计。

(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不锈钢桥架按本章钢制桥架定额乘以系数1.1计算。

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钢制桥架主结构设计厚度大于3mm时，定额人工、机械乘以系数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玻璃钢梯式桥架和铝合金梯式桥架定额均按不带盖考虑，如这两种桥架带盖板，则分别执行玻璃钢槽式桥架和铝合金槽式桥架项目的定额。

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)江南jn体育下载 以每片长度2m为一个基型片，需要在施工现场将基型片进行组合成桥架，以“100片”为计量单位计算，主材费另计。

(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)江南jn体育下载 支撑架以“100kg”为计量单位。适用于立柱、托臂及其他各种支撑架的安装。本定额已综合考虑了采用螺栓、焊接和膨胀螺栓3种固定方式，实际施工中，不论采用何种固定方式，定额均不做调整。

(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)桥架、托臂、立柱、隔板、盖板为外购件成品，连接用螺栓和连接件随桥架成套购买，计算质量可按桥架总重的7%计算。

(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.
