Prefabricated assembled laminated slab structure
The invention relates to the technical field of bridge engineering, and discloses a prefabricated assembled laminated slab structure which comprises a prefabricated bottom plate and a cast-in-place top plate arranged in a stacked mode, wherein the prefabricated bottom plate is formed by sequentially connecting a plurality of regular trapezoidal plates and inverted trapezoidal plates in a matched mode, and the edge slopes of the regular trapezoidal plates in the width direction are matched with the edge slopes of the inverted trapezoidal plates in the width direction. The prefabricated bottom plate is formed by splicing the regular trapezoidal plates and the inverted trapezoidal plates through the edge slopes, gaps between traditional segment splicing plates can be compressed to the maximumextent, the prefabricated bridge deck slab makes edge slope joints more and more compact in contact under the action of the gravity of the prefabricated bridge deck slab, and the stress performance is better. The tail ends of the shear teeth and the shear tooth-shaped structures are cow leg parts capable of transmitting shear force, so that tension needing to be transmitted between the prefabricated regular trapezoidal plates and the inverted trapezoidal plates is converted into the shear force transmitted between tooth blocks at the joints, and then the joint sections of the adjacent trapezoidal plates can transmit the tension to each other.
本发明涉及桥梁工程技术领域，公开一种预制拼装叠合板构造，包括叠设的预制底板和现浇顶板，预制底板由多块正梯形板和倒梯形板依次匹配衔接而成，正梯形板宽度方向边缘斜面与倒梯形板宽度方向边缘斜面适配。预制底板由正梯形板和倒梯形板通过边缘斜面拼装而成，可最大限度压缩传统节段拼装板之间的缝隙，预制桥面板在自身的重力作用下将使边缘斜面接缝间的接触愈加紧密，受力性能更好；剪力齿和剪力齿状结构末端为可传递剪力的“牛腿部”，使预制的正梯形板和倒梯形板间需要传递的拉力转化成接缝处齿块间传递的剪力，进而使相邻梯形板接缝断面可相互传递拉力。
