The invention discloses a detachable deck type steel bar truss laminated slab, and relates to the field of building structures. The problems that an existing steel bar truss prefabricated slab steel bar truss is wasted, the slab span is small, the number of supports is large, the slab thickness is large, electromechanical pipeline crossing is difficult, installation and construction are complex, and the construction period is prolonged are solved. According to the technical scheme, a steel bar truss in a conventional steel bar truss prefabricated slab is placed on the upper surface of a squarepyramid frustum protruding out of the upper surface of a prefabricated bottom plate; an embedded steel plate and a connecting steel bar are welded to a steel bar at the lower chord of the steel bar truss; the steel bar is anchored into the prefabricated bottom plate; the center line of a horizontal support at the bottom of the prefabricated bottom plate coincides with the center line of the protruding square pyramid frustum; and after post-poured concrete on the prefabricated bottom plate reaches the design strength, the connecting steel bar is cut off, and the steel bar truss is detached soas to be recycled next time.
本发明公开了一种可拆卸的上承式钢筋桁架叠合板，涉及建筑结构领域，解决了现有钢筋桁架预制板钢筋桁架白白浪费、板跨度小、支撑偏多、板厚偏大、机电管线穿越困难、安装施工繁琐、工期延长等问题。本发明采用的技术方案是：将常规钢筋桁架预制板中钢筋桁架搁置在从预制底板上表面凸出的正方形棱台上表面，钢筋桁架下弦钢筋焊有预埋钢板和连接钢筋，该钢筋锚入预制底板内，预制底板底水平支撑的中心线与凸出的正方形棱台的中心线重合，当预制底板上的后浇混凝土达到设计强度后割除连接钢筋将钢筋桁架拆卸以便下次周转使用。
