Description

Anticorrosion device of highway bridge tunnel structure and anticorrosion, waterproof and seismic structure thereof

The new model relates to a building component structure, in particular to an anti-corrosion device of a highway bridge tunnel structure and its anti-corrosion, waterproof and seismic structure.

The conventional anti-vibration device can be installed in two ways. The first is to install it on the bridge deck, which is generally called a metal rubber expansion joint. The rubber expansion joint includes a shell with a gap formed on the surface, and a shell arranged in the gap. The metal and a rubber shock-absorbing block can not only reduce the temperature stress caused by thermal expansion and contraction through the gap, but also can absorb vibration through the metal and the rubber shock-absorbing block to achieve the effect of shock absorption. The second is to install between the bridge pier and the bridge, generally called rubber shock absorber, the rubber shock absorber includes two mounting plates fixed to the bridge and the bridge pier with screws, and one set between the mounting plates The rubber shock-absorbing block also absorbs vibration through the rubber shock-absorbing block to achieve the effect of shock absorption.

However, no matter which kind of anti-corrosion device of highway bridge tunnel structure is installed outdoors, it is easy to be corroded by the atmosphere and reduce its service life. Examples but not limited to the following:

1. The rubber shock absorber is easily damaged by external substances such as dust or sand in the environment or physically damaged by collisions. Secondly, it may also be caused by chemical substances in the environment (such as vehicle exhaust substances, acid rain, cleaning Liquid) contact with chemical damage.

2. The metal and rubber shock-absorbing blocks are embrittled under the influence of ultraviolet radiation and environmental temperature difference, thereby reducing the shock-absorbing effect.

3. The atmosphere in the environment will enter the interior of the anti-seismic device, causing corrosion of the steel bars or screws inside, and reducing the crack resistance and tensile strength of the anti-seismic device, so that the anti-seismic device is gradually damaged and cannot be used effectively. .

Therefore, the purpose of the present invention is to provide an anti-corrosion, waterproof and shock-proof structure that can increase the service life.
