Abstract

带钢筋桁架翼缘板的预制预应力板及制作方法是一种具有双向受力性能的装配式混凝土叠合楼板的及制作方法,由预制预应力混凝土底板、预制混凝土翼缘条状板及分别浇筑在上下板内的钢筋桁架组成,底板与翼缘板之间留有穿电线管和钢筋的间隙。制作时先将钢筋桁架与混凝土翼缘条状板浇筑在一起,再将带钢筋桁架翼缘板翻转180度连同位于三角形钢筋桁架尖点的纵向钢筋和折线腹筋弯折部及横向分布筋共同压入已张拉预应力筋并布混凝土料的底板内,振捣混凝土并养护,形成带钢筋桁架翼缘板的预制预应力混凝土板。本发明能实现工厂高效率流水生产,浇筑叠合楼板整体性好,简化了楼板的施工工艺,能节省模板和用工量。
The invention relates to a prefabricated prestressed plate with a reinforced truss flange plate and a production method thereof, in particular to an assembly type concrete overlapped floor slab with a bidirectional mechanical performance and the production method thereof. The prefabricated prestressed plate consists of a prefabricated prestressed concrete base plate, a prefabricated concrete flange strip plate and reinforced trusses which are respectively cast in an upper plate and a lower plate; and a gap through which a wire tube and a reinforcing steel bar penetrate is reserved between the base plate and the flange plate. When the prefabricated prestressed plate is produced, the reinforced trusses are cast with the concrete flange strip plate together; the flange plate with the reinforced truss is turned by 180 degrees and is commonly pressed in the base plate which is provided with stretch-drawing prestressed bars and a concrete material together with a longitudinal reinforcing steel bar positioned at a sharp point of the triangular reinforced truss, a broken line bending part and a transverse distribution bar; and concrete is vibrated and cured to form the prefabricated prestressed concrete plate with the reinforced tress flange plate. According to the prefabricated prestressed plate and the production method thereof disclosed by the invention, high-efficiency streamline production of a factory is realized; the integrity of the cast overlapped floor slab is favorable; a construction process of the floor slab is simplified; and a template and the labor intensity can be saved.
