Bridge reinforcing and maintaining device
The invention discloses a bridge reinforcing and maintaining device which comprises two pieces of expansion joint profile steel symmetrically arranged at the two sides of an expansion joint gap and is characterized in that a lower steel plate and an upper steel plate are sequentially arranged on the upper portion of the expansion joint profile steel from bottom to top, and the upper steel plate, the lower steel plate and the expansion joint profile steel are fixedly connected through connecting bolts; and the bottom of the upper steel plate is provided with a first zigzag contact surface, the top of the lower steel plate is provided with a second zigzag contact surface which is matched with the first zigzag contact surface in a staggered mode, empty grooves are formed between the expansion joint profile steel located on the two sides, between the lower steel plates and between the upper steel plates, and elastic waterproof filling pieces are fixedly arranged in the empty grooves in an adhesive mode. The bridge reinforcing and maintaining device has the advantages that normal compression of the expansion joint is achieved by compressing or stretching the elastic waterproof filling pieces in the empty grooves, solid waste is isolated from entering the expansion joint, the zigzag connecting faces which are matched in a staggered mode are arranged between the upper steel plate and the lower steel plate, and certain structural stability can be kept continuously when connecting bolts fall off accidentally.
本发明公开了一种桥梁加固维修装置，包括对称设置在伸缩缝空隙的两侧的两个伸缩缝型钢，特点是伸缩缝型钢的上部从下至上依次设置有下钢板和上钢板，上钢板、下钢板和伸缩缝型钢通过连接螺栓固定连接，上钢板的底部设置有第一锯齿形接触面，下钢板的顶部设置有与第一锯齿形接触面相互交错配合的第二锯齿形接触面，位于两侧的伸缩缝型钢之间、下钢板之间及上钢板之间形成空槽，空槽内粘结固定设置有弹性防水填充件；优点是通过压缩或拉伸空槽中的弹性防水填充件，实现伸缩缝的正常压缩，并隔离固体垃圾进入伸缩缝，上钢板与下钢板之间设置相互交错配合的锯齿形连接面，能够在当连接螺栓意外脱落时，继续保持一定的结构稳定性。
