Bare concrete prefabricated bridge expansion device
The bare concrete prefabricated bridge expansion device comprises a left structure and a right structure, the left structure and the right structure are the same in structure and are arranged in a mirror image mode, the left structure is provided with a box body top plate and a box body bottom plate which are oppositely arranged up and down, and the side, away from the right structure, of the box body top plate is provided with a box body rear plate connected with the box body bottom plate; the upper portion of the other side of the box body is provided with edge beam steel connected with the box body top plate, the lower portion of the other side of the box body is provided with a box body front plate connected with the box body bottom plate, and reinforcing ribs and special-shaped ribs are arranged in the left structure. The thermal expansion and cold contraction deformation of the expressway bridge caused by the change of the environment temperature can be solved, and the method is widely applied to various expressway bridges.
本发明公开了种裸砼预制式桥梁伸缩装置，包括左结构、右结构，所述左结构、右结构相结构相同且镜像设置，所述左结构上下相对设置的箱体顶板、箱体底板，所述箱体顶板远离右结构的一侧设置与箱体底板连接的箱体后板，另一侧上部设置与箱体顶板连接的边梁钢，下部设置与箱体底板连接的箱体前板，所述左结构内设置加强筋与异形筋，本发明通过设置加强筋、异形筋能够保证桥梁伸缩缝的强度，构造简单、牢固耐用，能够解决高速公路桥梁由于环境温度的变化产生的热胀冷缩变形，广泛应用在各个高速桥梁。
