桥架及电缆作为机电安装工程的重要部分，施工好坏直接影响工程整体质量，这里选取桥架及电缆工程验收中屡见不鲜的施工问题，以供大家逐一对照引以为戒，提升质量管理水平。下面 山东电缆桥架厂家为您解答

As an important part of the electromechanical installation project, the construction quality of the bridge and cable directly affects the overall quality of the project. Here we select the construction problems that are common in the acceptance of the bridge and cable project, so that we can learn from each other and improve the quality management level. Next, Shandong cable bridge manufacturer will answer for you

线管和桥架连接使用波纹管，且未可靠固定

Corrugated pipes are used for the connection between the line pipe and the bridge and are not reliably fixed

桥架间跨接线应连接在连接片两端，不得接在连接片上

The jumper wire between bridges shall be connected at both ends of the connecting piece, and shall not be connected on the connecting piece

规范要求非镀锌电缆桥架间连接板的两端跨接铜芯接地线，接地线小允许截面积不小于4㎜2。

The specification requires that both ends of the connecting plate between non-galvanized cable trays shall be connected with copper core grounding wire, and the small allowable sectional area of the grounding wire shall not be less than 4 mm2.

桥架间连接片两端没有跨接地线

There is no jumper wire at both ends of the connecting piece between bridges

桥架间跨接线应连接在连接片两端，不得接在连接片上

The jumper wire between bridges shall be connected at both ends of the connecting piece, and shall not be connected on the connecting piece

【正确做法】

[Correct practice]

桥架间跨接线连接在连接片两端，符合要求

The jumper wire between bridges is connected at both ends of the connecting piece, which meets the requirements

桥架三通处三个方向都有支架，符合要求

There are supports in three directions at the bridge tee, which meet the requirements

桥架内电缆敷设用电线绑扎，且敷设混乱

The cable laying in the bridge is bound with wires, and the laying is chaotic

规范要求电缆敷设严禁有绞拧、铠装压扁、护层断裂和表面严重划伤等缺陷。

The specification requires that the cable laying shall be free from defects such as twisting, flattening of armor, breakage of protective layer and serious scratch on the surface.

【正确做法】

[Correct practice]

桥架内电缆敷设整齐、顺直，无绞拧

The cables in the bridge shall be laid in order and straight without twisting

桥架中电缆有中间接头

The cable in the bridge has an intermediate joint

桥架内电缆敷设混乱、无绑扎，支架螺杆过长，防火封堵不符合要求

The cable laying in the bridge is disordered, without binding, the support screw is too long, and the fireproof plugging does not meet the requirements

电缆桥架接地不符合要求，扁钢未固定

The grounding of cable tray does not meet the requirements, and the flat steel is not fixed

导线裸敷在梯架内，线缆堆集没有绑扎或绑扎不符合要求

The conductor is laid bare in the ladder, and the cables are stacked without binding or binding does not meet the requirements

电缆桥架跨越变形缝没有补偿装置，连接片螺栓不全，接地跨接未连接

The cable bridge crosses the deformation joint without compensation device, the connecting lug bolts are incomplete, and the grounding jumper is not connected

规范要求直线段钢制电缆桥架长度超过30m、铝合金或玻璃钢制电缆桥架长度超过15m设有伸缩节；电缆桥架跨越建筑物变形缝处设置补偿装置。

The specification requires that the length of steel cable tray in straight section is more than 30m, and the length of aluminum alloy or glass fiber reinforced plastic cable tray is more than 15m, with expansion joints; The compensation device shall be set at the place where the cable bridge crosses the deformation joint of the building.

钢制桥架与镀锌桥架混接，且没有连接片，底部开孔用螺栓连接，没有跨接线

The steel bridge is mixed with the galvanized bridge, and there is no connecting piece. The bottom opening is connected with bolts, and there is no jumper wire
