Abstract
The utility model discloses a lightening-proof road highway bridge and belongs to the field of highway bridge technology. The technical scheme of the utility model is that the lightening-proof road highway bridge comprises a bridge body, supporting bars, lightening arresters and bridge piers. The lightening-proof highway bridge is characterized in that two sides of the top part of the bridge body are provided with multiple supporting bars; a wire (I) is arranged in each supporting bar; the top part of each supporting bar is provided with a bridge pier; and the bottom part of the bridge pier is provided with a bearing platform and a foundation pile. Compared with the prior art, the lightening-proof highway bridge is advantageous by low cost, safety and reliability, so that damage of strong lightning wave to the highway bridge can be effectively avoided; and the lightening-proof highway bridge is simply structured and well designed with convenient usage.
Description
Technical field
The utility model relates to the Highway bridge technique field, relates in particular to a kind of lightning preventing highway bridge.
Background technology
Along with improving constantly of China's living standards of the people, highway bridge construction has also entered the fast-developing epoch.The Bridges on Highway electrification has begun to popularize, and the highway bridge basic configuration has the equipment such as street lamp, crisis phone only, electrified warning sign, electron camera, and these electronic equipments easily cause damage when highway bridge runs into thunderbolt.At present, the Bridges on Highway aspect adopts the mode of the plug-in single steel bar ground connection of simple bridge, can play anti-lightning strike effect, but when the dash current of lightning wave generation is excessive, ground connector can not fully be released the lightning wave electric current into the earth, the destruction that can not reliably avoid lightning wave to cause.
The utility model content
The purpose of this utility model is the deficiency that exists for prior art, a kind of lightning preventing highway bridge is provided, and this utility model has advantages of with low cost, safe and reliable, can effectively avoid powerful lightning wave to the damage of highway bridge, and simple in structure, reasonable in design, easy to use.
The purpose of this utility model is achieved through the following technical solutions: a kind of lightning preventing highway bridge, comprise beam body, support bar, lightning protection and bridge pier, both sides, described beam body top are provided with many support bars, be provided with wire I in support bar, support bar top is provided with lightning protection, described beam body bottom is provided with bridge pier, and the bridge pier bottom is provided with cushion cap and foundation pile.
Described lightning protection comprises shell and lightning rod, be provided with wire II, transformer, resistance and inductance coil in described shell, the end of described wire II is in series with the primary coil of transformer, the two ends of the secondary coil of transformer are connected with resistance, are in series with inductance coil on the primary coil of transformer and the wire II between lightning rod.
Wire I in the other end of described wire II and support bar is connected.
Be provided with a ground rebar in described bridge pier, one end of described ground rebar is connected with wire I, the other end connects the articulating reinforcing bar in cushion cap, is provided with an elongated ground rebar in described foundation pile, and the upper end of described elongated ground rebar is connected with described articulating reinforcing bar.
The beneficial effects of the utility model are: the utlity model has with low cost, safe and reliable advantage, the inductance coil of connecting on wire II can scabble the crest of lightning wave, reduce dash current, the primary coil of series transformer on wire II, absorb the energy of lightning wave, the electric resistance changing that is connected by the secondary coil of transformer becomes dissipation of heat to go out, and can effectively avoid so powerful lightning wave to the damage of highway bridge, and simple in structure, reasonable in design, easy to use.
