Multidirectional displacement bridge expansion device
The invention discloses a multidirectional displacement bridge expansion device. A plurality of joint-crossing steel plates which are arranged along the transverse bridge direction and are vertically arranged are pre-embedded in an elastic main body of an elastic expansion component, the joint-crossing steel plates are arranged along the bridge direction, traction steel frames are respectively arranged on the left and right sides of the joint-crossing steel plates, and a plurality of extension springs are arranged between the joint-crossing steel plates and the traction steel frames; the extension springs are hinged and matched with the cross-seam steel plate and the traction steel frame; and the traction steel frame is connected with the U-shaped channel steel through a connecting piece. A large joint-crossing steel plate is replaced by a plurality of vertical joint-crossing steel plates, each joint-crossing steel plate is connected with a bridge structure through an extension spring, and each joint-crossing steel plate and the corresponding extension spring can independently deform; the bridge expansion device can meet the requirements of vertical deformation, horizontal dislocation deformation of a transverse bridge, fan-shaped deformation in the transverse bridge direction and distortion deformation in the transverse bridge direction.
本发明公开了一种多向变位桥梁伸缩装置，通过在弹性伸缩构件的弹性主体内部预埋多个沿横桥向排列且竖立设置的跨缝钢板，将跨缝钢板顺桥向设置，在其左右两侧分别设置牵引钢架，在跨缝钢板与牵引钢架之间设有多个拉伸弹簧，将拉伸弹簧与跨缝钢板和牵引钢架铰接配合；牵引钢架则通过连接件与U型槽钢实现连接。通过多个竖立的跨缝钢板来代替一个大的跨缝钢板，并通过拉伸弹簧来实现各个跨缝钢板与桥梁结构连接，各个跨缝钢板和其对应的拉伸弹簧都能够独立实施变形，使得桥梁伸缩装置能够满足竖向变形、横桥水平错位变形、横桥向扇形变形以及横桥向扭曲变形。
