Cable tray is widely used in petroleum, chemical industry, electric power, telecommunications and other industries. It is mainly used for the laying of power cables, control cables, lighting lines and telecommunications cables. The bottom plates of various existing cable trays are flat plate structures. Due to the large span of the bridge, the weight of the cable and the bridge itself is also large. In order to ensure the bearing capacity, the metal materials pressing the bridge tray need to have corresponding thickness and strength. At present, the steel plate of about 3mm is generally used to meet the strength requirements. The bridge made of such thick steel plate has considerable weight, so the manufacturing cost is relatively high, which brings great difficulties to transportation and construction lifting. Moreover, during the operation of the line after the completion of construction, due to its own heavy, coupled with the natural loosening of vibration fixing parts and supporting parts, the bridge gradually sinks, which is easy to lead to accidents and increase the difficulty and amount of maintenance. These situations have become common and long-standing problems in the project.

针对上述问题，轻型防震电缆桥架被逐渐获得关注，并发展起来了。该电缆桥架可以在保证原承载能力的情况下减轻桥架自重，降低能耗，降低因震动而产生的隐患。

In view of the above problems, light shockproof cable bridge has been gradually paid attention to and developed. The cable bridge can reduce the dead weight of the bridge, reduce energy consumption and reduce the hidden dangers caused by vibration under the condition of ensuring the original bearing capacity.

轻型电缆桥架结构：包括底板和分置于底板两端并与其互相垂直的桥架梯边，底板和梯边为整块钢板冲压而成，在底板和梯边的连接处设有倒S弯，能够减弱震动产生的冲击力,起到防震的功能。底板上设有纵横加强筋。即在底板宽度方向的中间部位设置横向加强筋，横向加强筋的两侧设有纵向加强筋。加强筋为长圆槽形。加强筋为模具一次冲压成形，错落有致，外形美观。

Light cable bridge structure: it includes the bottom plate and the bridge ladder edge placed at both ends of the bottom plate and perpendicular to each other. The bottom plate and ladder edge are stamped from a whole steel plate. An inverted S-bend is set at the connection between the bottom plate and ladder edge, which can reduce the impact force caused by vibration and play the function of earthquake prevention. The bottom plate is provided with vertical and horizontal stiffeners. That is, transverse stiffeners are set in the middle of the width direction of the bottom plate, and longitudinal stiffeners are set on both sides of the transverse stiffeners. The stiffener is in the shape of long circular groove. The stiffener is formed by one-time stamping of the die, which is staggered and beautiful in appearance.

电缆桥架底板上增加了加强筋后，所用材料料厚非常薄，可以使钢板厚度减小了一半，同等条件下，桥架重量将近减小了一半，而强度和承载能力仍保持不变，大大降低了能耗，节省了施工成本，降低了运输费用、采购成本和施工难度，解决了因为桥架自重过大而导致的塌陷问题。同时，在底板和梯边的连接处设置的倒S弯，能够解决因为震动而产生的冲击力，具有防震的功能。采用该电缆桥架后，原来需用专门设备才能完成举升操作，人工就可完成。这样大幅度提高了施工效率，提高了工作进度，节省了施工费用，降低了能耗，提高了经济效益。。

The thickness of the steel plate used in the bridge is nearly half that of the steel plate used in the construction, and the energy consumption can be greatly reduced by strengthening the thickness of the steel plate and the thickness of the steel plate used in the bridge. After the construction, the energy consumption can be reduced by nearly half, and the thickness of the steel plate is still the same as that of the bottom plate, The problem of collapse caused by excessive dead weight of the bridge is solved. At the same time, the inverted S-bend set at the connection between the bottom plate and the ladder edge can solve the impact force caused by vibration and has the function of earthquake prevention. After the cable bridge is adopted, the lifting operation can be completed only with special equipment, which can be completed manually. In this way, the construction efficiency is greatly improved, the work progress is improved, the construction cost is saved, the energy consumption is reduced, and the economic benefit is improved..
