Abstract

The invention discloses a horizontal splicing bridge, which comprises a bridge main board, and the inner surface of the bridge main board is movably connected with a splicing mechanism; the splicing mechanism comprises a hexagonal mounting frame, a supporting vibration plate is movably connected to the top of the hexagonal mounting frame, positioning rings are movably connected to the top and the bottom of the inner surface of the hexagonal mounting frame, a vibration column is movably connected to the middle of the top of each positioning ring, and a vibration ball is movably connected to the bottom of each vibration column; a V-shaped internal energy mechanism is movably connected to the bottom of the outer surface of the vibration ball, an adjusting mechanism is movably connected to the inner surface of the supporting frame plate, and an electromagnetic ellipsoid is movably connected to the side, close to the vibration ball, of the inner surface of the supporting frame plate. By means of self vibration and arc-shaped structure design, connection points between bridges are strengthened, generated vibration force is dispersed, internal dispersion is achieved, the transmission direction of vibration is changed, mutual counteracting of vibration is achieved, and protection of the connection positions of the bridges is achieved.

Description

technical field

[0001] The invention relates to the technical field of bridges, in particular to a horizontal splicing bridge. Background technique

[0002] In recent years, highway reconstruction and expansion projects are increasing day by day. Most of them are widened directly on the basis of the original roadbed and bridges. Bridge splicing is the key and difficult point in highway reconstruction and expansion projects.

[0003] According to Chinese patent CN108797303A, the threaded rod is driven to move under the limit of the limit block through the turning knob arranged on the stabilizing block, so that the block fixed on the threaded rod can be moved out of the card slot more conveniently, and the fixed plate is fixed. Convenient disassembly and installation, by setting and pulling the first connecting rod and the second connecting rod to rotate on the rotating block, it can be fixed according to the distance between the horizontal plate and the bridge plate, so that ...
