Seamless expansion device, bridge deck expansion joint structure and paving method of bridge deck expansion joint structure
The invention relates to the technical field of bridge expansion and contraction devices, in particular to a seamless expansion and contraction device, a bridge floor expansion and contraction joint structure and a paving method thereof.The seamless expansion and contraction device comprises two sets of displacement box bodies, a joint crossing plate and a reinforcing piece, and displacement sliding grooves are horizontally formed in the opposite sides of the two displacement box bodies; the joint crossing plate abuts against the upper end face of the displacement box body, connecting pieces slidably connected to the displacement sliding grooves are arranged on the two sides of the joint crossing plate so that the joint crossing plate can slide relative to the displacement box body, each reinforcing piece comprises a reinforcing pipe, a reinforcing rod, an inclined supporting rod and an elastic piece, the reinforcing pipes are arranged on the displacement box body or the beam body, the reinforcing pipes are vertically arranged, and the inclined supporting rod is arranged between the reinforcing pipes. The reinforcing rod is inserted into the reinforcing pipe in a sliding mode in the axial direction, one end of the inclined supporting rod is hinged to the lower end face of the middle of the seam crossing plate, the other end of the inclined supporting rod is hinged to the reinforcing rod, and the elastic piece is arranged between the reinforcing pipe and the reinforcing rod. The joint-crossing steel plate has the effect of improving the structural strength of the joint-crossing steel plate.
本申请涉及桥梁伸缩装置技术领域，尤其涉及一种无缝式伸缩装置、桥面伸缩缝结构及其铺装方法，一种无缝式伸缩装置，包括位移箱体、跨缝板以及加强件，位移箱体设置有两组，两所述位移箱体的相对侧沿水平开设有位移滑槽，跨缝板抵接于位移箱体的上端面，跨缝板的两侧均设置有滑移连接于位移滑槽的连接件使得跨缝板能够相对位移箱体进行滑移，每组加强件包括加强管、加强杆、斜撑杆以及弹性件，加强管设置于位移箱体或者梁体，加强管呈竖向设置，加强杆沿轴向滑移插设于加强管，斜撑杆的一端铰接于跨缝板中部下端面，斜撑杆的另一端铰接于加强杆，弹性件设置于加强管和加强杆之间。本申请具有提高跨缝钢板的结构强度的效果。
