[0002] Steel bridges are a common building structure widely used in highways, railways, urban transportation and other fields. The thermal and electrical conductivity of steel bridges have an important impact on the safety and service life of bridges. Compared with thermal conductivity, steel has poor electrical conductivity and high resistivity, which means that the current will be greatly hindered when propagating in the steel bridge. This characteristic makes steel bridges vulnerable to lightning strikes in thunderstorm weather conditions.
[0003] In the existing technology, in order to improve the lightning resistance of steel bridges, lightning protection facilities such as lightning rods and lightning strips can be installed on the surface of the bridge. However, there is still a possibility that lightning will strike the steel trestle plates. Since steel trestle plates are generally made of steel and have conductive properties, when the steel trestle plates are struck by lightning, the steel trestle plates will conduct the current, causing people walking on the bridge deck to be electrocuted and get electric shocks. The safety needs to be improved, and it is necessary to propose an anti-electric shock structure for steel trestle plates to solve the above problem. Utility Model Content

It also includes an anti-electric shock component for protecting the trestle board main body 1 from electric shock, and the anti-electric shock component is arranged on the top surface of the support plate 3. The anti-electric shock component includes: an insulating plate 2, the insulating plate 2 is fixedly installed on the top surface of the trestle board main body 1, a fixing frame 4 is fixedly installed on the inner top surface of the trestle board main body 1, and several first rubber plates 5 and two arc plates 7 are fixedly installed on the bottom surface of the fixing frame 4. A second rubber plate 8 is fixedly installed on the bottom surface of the arc plate 7, and a second protective plate 9 is fixedly installed on the bottom surface of the second rubber plate 8. The bottom surface of the first rubber plate 5 is fixedly installed with a first protective plate 6. Elastic plates 11 are respectively fixedly installed on both sides of the trestle board main body 1, and a first conductive plate 12 is fixedly installed on one side of the elastic plate 11.
[0023] In this embodiment, a conductive cable 13 is fixedly installed on one side of the first conductive plate 12, and second fixing holes 14 are respectively opened on both sides of the trestle plate main body 1. The second fixing holes 14 are movably connected to the conductive cable 13. One end of the conductive cable 13 is fixedly installed with a second conductive plate 15, and the second conductive plate 15 is fixedly installed to the inner side of the trestle plate main body 1. A plurality of threaded columns 16 are fixedly installed on the bottom surface of the support plate 3, and a plurality of first circular through holes are opened on the top surface of the trestle plate main body 1.

A plurality of fixing bars 18 are fixedly installed on the top surface of the insulating plate 2, and a rubber frame 19 is fixedly connected to the outside of the insulating plate 2. Two L-shaped plates 20 are respectively fixedly installed on both sides of the trestle plate main body 1.
[0024] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: by setting the trestle board main body 1, when the user needs to lay the steel trestle board, the user uses the lifting cable to hook the L-shaped plate 20 so that the trestle board main body 1 is moved and laid on the steel trestle, so that the first protective plate 6 and the second protective plate 9 are in contact with the supporting steel beam of the steel trestle, and the trestle board main body 1 is supported, and the bottom surface of the trestle board main body 1 is strengthened by the setting fixing frame 4. Since the curved plate 7 is curved, it can bend to a certain extent when the trestle board main body 1 is pressed down, so that it can be used in conjunction with the first rubber plate 5 and the second rubber plate 8 to The bottom surface of the trestle board body 1 is shock-absorbing, and the first rubber plate 5 and the second rubber plate 8 are protected by the first protective plate 6 and the second protective plate 9. At the same time, the insulating plate 2 is provided. The insulating plate 2 is composed of resin and glass fiber, that is, glass fiber reinforced plastic, and is made by a pultrusion molding process. This process makes the insulating plate 2 have high compressive strength and good dimensional stability, and the insulating plate 2 has high strength, corrosion resistance, non-conductivity and flame retardancy. Therefore, the insulating plate 2 effectively insulates the top surface of the trestle board body 1 and can withstand a certain downward pressure. When an electric shock occurs, it effectively blocks the spread of current. At the same time, by setting the rubber The rubber frame 19 separates and protects the outside of the insulating plate 2. At the same time, when the trestle board body 1 is installed, the first conductive plates 12 on one side of the adjacent trestle board body 1 will contact each other, so that the trestle board body 1 is connected as one. The installer installs the cable on the first conductive plate 12 on the side of the last trestle board body 1 and conducts the current into the soil through the lightning rod for grounding. Then, when an electric shock occurs, the person walks on the top surface of the insulating plate 2, and the insulating plate 2 can be better insulated to prevent electric shock. The current of the trestle board body 1 is conducted into the soil for grounding through the first conductive plate 12, the conductive cable 13 and the second conductive plate 15. The first rubber plate 5 is used to insulate the trestle board body 1 and the bridge to prevent current from being transmitted to the bridge, thereby achieving a good anti-electric shock effect, thereby comprehensively achieving the effect of preventing users from being electrocuted. When the trestle board body 1 or the bridge is struck by lightning, the insulating plate 2 can be used to insulate the trestle board body 1 from the human body, and the first rubber plate 5 and the second rubber plate 8 can be used to insulate the bottom surface of the trestle board body 1. By means of a grounding wire, the people on the top surface of the trestle board body 1 are further prevented from being electrocuted, and the anti-electric shock effect is good. In addition, the first rubber plate 5 and the second rubber plate 8 can be used to reduce shock on the bottom surface of the trestle board body 1, which is more practical.
