Prefabricated local composite floor slab
The invention discloses a prefabricated local composite floor slab. The prefabricated local composite floor slab comprises a middle full prefabricated slab and peripheral composite prefabricated slabswhich are integrated through concrete pouring, wherein the peripheral composite prefabricated slabs are located on the two sides of the middle full prefabricated slab in the width direction, a plurality of penetrating through holes are formed in the middle of the middle full prefabricated slab in the length direction at equal intervals, a plurality of longitudinal first steel bars and transversesecond steel bars are pre-buried in the positions, above the through holes, of the middle full prefabricated slab, a plurality of longitudinal third steel bars are pre-buried in the positions, below the through holes, of the middle full prefabricated slab, a plurality of longitudinal fourth steel bars are pre-buried in the peripheral composite prefabricated slabs, and the fourth steel bars and thethird steel bars are parallel to each other in the same plane. According to the prefabricated local composite floor slab, the self weight of the concrete composite floor slab is effectively reduced,the amount of concrete poured on site is greatly reduced, a steel truss does not need to be arranged, the use amount of extra steel bars in a floor is reduced, the workload of on-site steel bar binding is reduced, and a slab bottom support is not needed in the construction process, so that the construction cost and the construction period are effectively saved.
本发明公开了一种预制局部叠合楼板，包括通过混凝土浇筑为一体结构的中间全预制板和四周叠合预制板，四周叠合预制板位于中间全预制板沿宽度方向的两侧，中间全预制板的中部沿长度方向等距离开设有多个贯穿的通孔，通孔上方的中间全预制板中预埋有多根纵向第一钢筋和横向第二钢筋，通孔下方的中间全预制板中预埋有多根纵向第三钢筋，四周叠合预制板中预埋有多根纵向第四钢筋，第四钢筋与第三钢筋在同一平面内相互平行。本发明有效地降低了混凝土叠合楼板的自重，大大减少了现场浇筑的混凝土量；不需要设置钢桁架，减少了楼板内额外钢筋的用量，减少了现场钢筋绑扎的工作量；施工过程中不需要设置板底支撑，有效节省施工成本和工期。
