Prefabricated concrete laminated slab
The invention discloses a prefabricated concrete laminated slab. The prefabricated concrete laminated slab comprises a cuboid slab body, reinforcing grooves are formed in the upper end face of the slab body in parallel, dovetail grooves are transversely formed in the two end faces, perpendicular to the reinforcing grooves, of the slab body, the section of each reinforcing groove is in an inverted-T shape, truss steel bar sets are arranged in the reinforcing grooves, each truss steel bar set comprises erecting ribs and tie bars, the erecting ribs are longitudinally arranged, reinforcing bent ends are arranged at the bottoms of the erecting ribs and extend into the slab body, and the tie bars are parallel to the slab body. Compared with the prior art, the prefabricated concrete laminated slab has the advantages that the structure is clear, use is convenient, a formwork can be omitted when the prefabricated concrete laminated slab is used as a floor plate, a post-pouring concrete layer and a prefabricated part layer are firmly combined through the design of the truss steel bar sets and the reinforcing grooves, the weight of a whole component is lighter due to a light filler, the truss steel bar sets can be directly used for hoisting, hidden beams are additionally provided with reinforcing ribs to improve the tensile, compression-resistant and fracture-resistant performance, the structure is stable, construction is fast and convenient, and the practicability and the market popularization value are very high.
本发明公开了一种预制混凝土叠合板，包括长方体的板体，板体上端面平行设有加固槽，板体垂直于加固槽的两个端面横向设有燕尾槽，加固槽的截面呈倒T字形，加固槽内设有桁架钢筋组；桁架钢筋组包括架立筋和拉结筋，架立筋纵向设置，架立筋底部设有加固弯曲端，加固弯曲端伸入板体内部，拉结筋平行于板体设置。本发明与现有技术相比的优点在于：结构明确，使用方便，作为楼层板使用可以省去模板，桁架刚进组和加固槽的设计使后浇混凝土层与预制构件层结合牢固；轻质填充物使整体构件重量更轻便；桁架钢筋组可以直接用于吊装，暗梁增加加强筋增加抗拉、抗压、抗折的性能，结构稳定、施工快捷方便。具有很强的实用性和市场推广价值。
