Self-leveling prefabricated assembly type pavement slab for airport pavement slab replacement
The invention provides a self-leveling prefabricated assembly type pavement slab for airport pavement slab replacement, which comprises a prefabricated slab adopting a profile steel frame, a reserved groove is arranged at the bottom corner of the prefabricated slab, and a leveling bolt is arranged in the reserved groove; the profile steel frame comprises upper angle steel and lower angle steel, the upper angle steel clings to the inner wall and the top wall of the reserved groove, and the lower angle steel is fixed on the ground; the leveling bolt comprises an upper screw rod, a lower screw rod and an adjusting nut, the upper screw rod is fixed with the upper angle steel, the lower screw rod is fixed with the lower angle steel, the upper screw rod and the lower screw rod are connected through the adjusting nut, and the adjusting nut is rotated to adjust the distance between the upper screw rod and the lower screw rod. The leveling bolt transmits force to a base layer through the profile steel, bidirectional adjustment is achieved through the middle nut, local stress at the bolt is reduced, the leveling speed is high, side face grooves and slab joints are treated in a coordinated mode, and the working procedure is simplified.
本发明提供了一种用于机场道面换板的自调平预制装配式道面板，包括采用型钢边框的预制板，预制板的底角处设置预留凹槽，预留凹槽内设置有调平螺栓；所述型钢边框包括上角钢和下角钢，上角钢紧贴预留凹槽内壁和顶壁，下角钢固定在地面上；所述调平螺栓包括上螺杆、下螺杆和调节螺母，其中上螺杆与上角钢固定，下螺杆与下角钢固定，上螺杆和下螺杆之间通过调节螺母连接，旋转调节螺母以调节上螺杆和下螺杆之间的间距。本发明的调平螺栓通过型钢传力于基层，且通过中间螺母实现双向调节，减小了螺栓处的局部应力且调平速度快，侧面凹槽与板缝协调处理，工序简化。
