在安装济南电缆桥架时,要准确测量电缆桥架的各段长度和角度,采用电缆桥架厂标准件和工厂预制件,是为了减少现场切割桥架,保证工程质量。下面就来看看电缆桥架安装过程中细节事项汇总。
When installing the cable tray in Jinan, the length and angle of each section of the cable tray shall be accurately measured, and the standard parts and factory prefabricated parts of the cable tray factory shall be used to reduce the cutting of the cable tray on site and ensure the project quality. Now let's take a look at the summary of details during the installation of cable tray.
敷设在竖井内和穿越不同防火区的桥架,应按设计要求位置,有防火隔离措施,电缆桥架在电气竖井内敷设可采用角钢固定。
The cable tray laid in the shaft and crossing different fire zones shall be provided with fire isolation measures according to the design requirements. The cable tray laid in the electrical shaft can be fixed with angle steel.
托臂是直接支承托盘、梯架单独固定的刚性部件,托臂有螺栓固定可预埋螺栓,也可采用膨胀螺栓,也可卡接。
The corbel is a rigid part that directly supports the tray and the ladder and is fixed separately. The corbel can be fixed with bolts, embedded bolts, expansion bolts or clamped.
电缆桥架水平敷设时,支撑跨距一股为1.5-3m,电缆桥架垂且敷设时固定点间距不宜大于2m。桥架弯通弯曲半径不大于300mm时,应在跨距弯曲段与直线段结合处300-600mm的直线段侧设置一个支架、吊架。支、吊架和桥架安装须考虑电缆敷设弯曲半径满足规范很小弯曲半径。
When the cable tray is laid horizontally, the support span is 1.5-3m. When the cable tray is laid vertically, the spacing between fixed points should not be greater than 2m. When the bending radius of the bridge is not more than 300mm, a support and hanger shall be set at the side of the 300-600mm straight section at the junction of the span bending section and the straight section. For the installation of supports, hangers and bridges, it must be considered that the bending radius of cable laying meets the requirements of very small bending radius.
门型角钢支架的安装:梯型桥架沿墙垂直敷设,可使用门型角钢支架,支架的固定应尽可能配合土建施工预埋;也可在土建施工中预埋开角螺栓,用开角螺栓固定支架;也可以采用膨胀螺栓固定。
Installation of gate type angle steel support: the ladder type cable tray is vertically laid along the wall, and the gate type angle steel support can be used. The support shall be fixed in coordination with the civil construction as far as possible; Open angle bolts can also be embedded in civil construction, and the bracket can be fixed with open angle bolts; Expansion bolts can also be used for fixing.

梯型角钢支架的安装:桥架沿墙、柱水平安装时,托壁需安装在异型钢立柱上,而立柱要安装在梯型角钢支架上,使柱和墙上的桥架固定支架(或托臂)在同一条直线上。底架与门型架焊接时,焊角高度5mm。
Installation of ladder type angle steel support: when the cable tray is horizontally installed along the wall and column, the supporting wall shall be installed on the special-shaped steel column, and the column shall be installed on the ladder type angle steel support, so that the fixed support (or bracket) of the cable tray on the column and the wall is in the same straight line. When the underframe is welded with the portal frame, the weld fillet height is 5mm.
电缆桥架立柱侧壁式安装:立柱是直接支承托臂的部件,分工字钢槽钢、角钢、异型钢立柱;立柱可以在墙上、柱上安装、也可悬吊在梁板上安装。做法在混凝土可预埋铁件;砌体可砌筑预制砌块;也可以采用膨胀螺栓但须在混凝土强度C20或砖强度在MU10以上的砖砌体上。
Side wall installation of cable tray column: column is a component that directly supports the corbel, including channel steel, angle steel and special-shaped steel column; The column can be installed on the wall, on the column, or suspended on the beam and slab. Method: embedded iron parts in concrete; Masonry can be built with prefabricated blocks; Expansion bolts can also be used, but must be used on brick masonry with concrete strength C20 or brick strength above MU10.
电缆桥架应敷设在易燃易爆气体管和热力管道的下方,当设计无要求时,与管道的很小净距,符合一般规定。更多相关事项的了解就来我们网站http://www.sddlqj.cn一起咨询吧!
The cable tray shall be laid under the flammable and explosive gas pipe and heat pipe. When there is no design requirement, the clear distance between the cable tray and the pipe shall be very small, which shall comply with the general provisions.
