Local UHPC reinforced efficient prefabricated concrete laminated plate
The invention discloses a local UHPC reinforced efficient prefabricated concrete laminated plate. Crossed bottom ribs and pre-embedded bolt columns are arranged in each prefabricated UHPC reinforcingblock, and a groove is reserved in the bottom surface. The prefabricated UHPC reinforcing blocks are distributed at the edge of a prefabricated concrete bottom plate, one side of an angle steel connecting piece is installed in the bottom surface groove of each UHPC reinforcing block, and a lead block is inlaid at the corner; after the prefabricated concrete bottom plate is installed in a buildingstructure, the other side of each angle steel connecting piece is connected with the building structure through bolts; and ordinary steel bars are laid on the upper portion, and the cast-in-place concrete is poured on the prefabricated concrete bottom plate. According to the local UHPC reinforced efficient prefabricated concrete laminated plate, a prefabricated UHPC shell with excellent performance is used at the joint of the lower part of the prefabricated concrete laminated plate, the stress performance is improved, the advantages of the prefabricated UHPC shell and the prefabricated concrete laminated plate are combined, and the construction cost is reduced. The connection between the prefabricated laminated plate bottom plate and the building structure is carried out through the special angle steel connectors, so that the problem that the mounting efficiency is affected due to the fact that the prefabricated laminated plate bottom ribs extend out is solved, and the connection strength and the energy consumption capability are enhanced.
本发明公开了一种局部UHPC增强的高效装配式混凝土叠合板，在预制UHPC增强块中设置交叉底筋和预埋螺栓柱，底面留设凹槽；在预制混凝土底板的边缘分布设置有所述预制UHPC增强块，角钢连接件一侧安装于UHPC增强块的底面凹槽内，在折角处镶嵌铅块；预制混凝土底板安装于建筑结构中后，通过螺栓将角钢连接件另一侧与在建筑结构连接；铺设上部普通钢筋，浇筑所述现浇混凝土浇筑于所述预制混凝土底板上。本发明将性能优越的预制UHPC壳用于预制混凝土叠合板下部连接处，提高受力性能，结合二者的优势，降低造价，通过特制角钢连接器进行预制叠合板底板和建筑结构的连接，解决预制叠合板底筋伸出影响安装效率的问题，增强连接强度和耗能能力。
