Several types of expansion joints often used in bridge construction

点击数:860 2016-04-22 Hits: 860

Bridges play a great role in the economic lifeline of our country. We are talking about the types of bridge expansion joints that are practically used in engineering from a professional perspective.

Below, we will introduce several types of expansion joints often used in bridge construction from a professional perspective.

、钢制支承式伸缩缝,是用钢材装配制成的,能直接承受车轮荷载的一种构造。 1. Steel-supported expansion joints are made of steel assembly and can directly bear wheel loads. Because various heavy-duty vehicles are often used on those elevated roads, this type of telescopic device was mostly used for steel bridges, and now it is also used for concrete beams.

、无缝式伸缩装置,是接缝构造不伸出桥面时,在桥梁端部的伸缩间隙中填入弹性材料并铺上防水材料,然后在桥面铺装层铺筑粘弹性复合材料,使伸缩接缝处的桥面铺装与其它铺装部分形成一连续体,以连接缝的沥青混凝土等材料的变形承受伸缩的一种构造。 2. Seamless telescopic device, when the joint structure does not protrude from the bridge deck, fill in the elastic material in the telescopic gap at the end of the bridge and pave the waterproof material, then pave the viscoelastic composite material on the bridge deck A structure in which the bridge deck pavement at the expansion joint and other pavement parts form a continuous body, and the deformation of the asphalt concrete and other materials connected to the joint is subjected to expansion and contraction. Played a great role in building bridges. This type of deformed seam is well sold in our Ruishu deformed seam device in Changshu.

、橡胶组合剪切式伸缩缝,这类伸缩装置是一种具有刚柔结合的装置。 3 , rubber combined shear expansion joints, this type of expansion device is a device with rigid and flexible combination. This deformation seam can make the car run smoothly, regardless of the weight of the car.

、模数支承式伸缩缝,这类伸缩装置利用吸震缓冲性能好又容易做到密封的橡胶材料,与强度高刚性好的异型钢材组合的,在大位移量情况下能承受车辆运行。 4. Modular-supported expansion joints. This type of expansion device uses rubber materials with good shock absorption and cushioning properties and is easy to seal. It is combined with special-shaped steel with high strength and rigidity, and can withstand vehicle operation under large displacement.

The above are the different bridge expansion joints introduced by Changxin Ruixin Deformation Joints for you. Different forms have different characteristics and application advantages.

If you have something to add, we at Changshu Ruixin Deformation Sewing Device welcome your suggestions at any time, and hope that each project can pay more attention when it is operating.
