A telescopic adjustment and elevation of the bridge joint device on both sides in the beam are respectively provided with a side beam, the lateral side beam is welded with a plurality of anchor interval linear distribution of ring beam and anchor plate, while below the beam is provided with a plurality of beams, the two ends of the beam by controlling the displacement of spring is installed in the box on both sides of the box are welded, displacement of anchor in the middle top beam and the beam connecting box are respectively welded at both ends of the displacement; and on both sides of the edge beam. A plurality of compensating plate are respectively and the beam and side beam width in the beam and side beam on the surface is covered with an anchoring hole in the welding, and the compensating plate and beam or side beam anchor welding, making it around the periphery of the plate and the beams or edge beam welding. The utility model has the advantages that: after the original bridge telescopic micro surfacing after paving joint device increases the compensating plate, eliminating or greatly reducing the height and the bridge expansion joint device, improve the driving comfort, to avoid the impact of the expansion joint device of vehicle through the extension of the expansion joint device the service life.
【技术实现步骤摘要】
本技术涉及一种调整与桥面高差的伸缩缝装置,主要用在经过微表处的桥面 的伸缩缝处。
技术介绍
现有的一种伸缩缝装置如图1和图2所示,在中梁2的两侧各设有一根边梁1,在 边梁1的外侧焊接有间隔直线分布的多个锚环锚板4 (呈梳齿状);在边梁1和中梁2的下 面设有多个横梁8,横梁8的两端通过控制弹簧5安装在位移箱6内,在位移箱6两侧焊接 有锚钉7,中梁2与横梁8的中部上面连接。两端的位移箱6分别与两边的边梁1焊接。在 应用时,两个边梁1的外侧的锚环锚板4插入桥面伸缩缝的两端内。经过微表处的桥面在伸缩缝处产生高差(即微表处的桥面与伸缩缝装置表面的 高度差),由于这种高差的影响,车辆通过时产生振动,舒适性极差,同时对伸缩缝产生了 更大的冲力,在这种长时间冲力的作用下就会导致伸缩装置边梁、中梁或横梁的断裂,缩 短了伸缩缝装置的使用寿命。
技术实现思路
本技术旨在提供一种调整与桥面高差的伸缩缝装置,以解决现有技术存在的 由于伸缩缝处的高差而缩短伸缩缝装置的使用寿命的问题。本技术的技术方案是一种调整与桥面高差的伸缩缝装置,在中梁的两侧各 设有一根边梁,在该边梁的外侧焊接有间隔直线分布的多个锚环锚板,在该边梁和中梁的 下面设有多个横梁,该横梁的两端通过控制弹簧安装在位移箱内,在该位移箱两侧焊接有 锚钉,该中梁与横梁的中部上面连接;两端的位移箱分别与两边的边梁焊接,其特征在于, 在所述的中梁和边梁的上表面覆盖有分别与该中梁和边梁等宽的多个补差板,在该补差板 上设有锚固焊孔并与该中梁或边梁锚焊,该补差板的周边与该中梁或边梁焊接。所述的补差板为平行四边形,其两个锐角为40 50°,在 ...
