Abstract

The invention relates to the technical field of expansion joint construction, in particular to an expansion joint device. The expansion joint device is arranged on a bridge concrete layer and comprises a first bridge body, a second bridge body and an expansion joint. The first bridge body is provided with a first fixing piece; the second bridge body is provided with a second fixing piece; the upper portions of the first fixing piece and the second fixing piece are provided with lap joint pieces. Each lap joint piece comprises a lintel and a lintel limiting and fixing piece; a plurality of lintel limiting and fixing pieces and lintels are fixedly arranged on the first fixing piece and the second fixing piece at intervals; one end of the lintel is fixedly connected with the first fixing piece or the second fixing piece, and the other end can move freely; the first fixing piece or the second fixing piece is connected with a first fixing mechanism arranged in the first bridge body and a first fixing mechanism arranged in the second bridge body. The lintel is connected with a second fixing mechanism arranged in the first bridge body and the second bridge body. The device is small in vibration, high in bearing capacity and convenient to construct.

Description

technical field [0001] The invention relates to the technical field of expansion joint construction, in particular to an expansion joint device. Background technique [0002] Construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate part along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation into two independent parts, so that the building or structure can be expanded horizontally along the long direction. [0003] In construction such as highways, expansion joints are very common. For continuous bridge decks, cracks often appear on the surface pavement. To solve the problem, pre-cut the bridge deck, set the joints, or use a softer pavement layer to absorb the cracks, or install small expansion devices. Combin...
