Bidirectional self-stress prefabricated slab and prefabricating method thereof
The invention relates to a bidirectional self-stress prefabricated slab and a prefabricating method thereof.The bidirectional self-stress prefabricated slab comprises expansive concrete, a prefabricated slab base and a self-stress device, self-stress tensioning plates distributed in the longitudinal direction and the transverse direction are caused to move outwards through expansion of the poured expansive concrete, the self-stress tensioning plates drive self-stress ribs to be tensioned, and the self-stress ribs are tensioned; meanwhile, the self-stress tension plate reversely applies longitudinal and transverse bidirectional self-stress to the prefabricated plate, the bidirectional self-stress plate is high in longitudinal and transverse rigidity and integrity and has the advantages of being high in quality, simple in process, low in manufacturing cost, free of mud jacking, environmentally friendly and the like, and the problems that a common prefabricated plate is low in rigidity and prone to cracking, and a bidirectional prestressed prefabricated plate is high in manufacturing cost, complex in process, poor in durability and the like are solved.
本发明涉及一种双向自应力预制板及其预制方法，所述双向自应力预制板包括：膨胀混凝土、预制板底座和自应力装置，通过浇筑的膨胀混凝土膨胀引起布设在纵横两个方向的自应力张拉板外移，自应力张拉板带动自应力筋张拉，同时自应力张拉板反向给预制板施加纵横双向的自应力，双向自应力板纵横向刚度和整体性强，具有质量高、工艺简单、造价低、不用压浆、绿色环保等特点，解决了普通预制板刚度低、易开裂、双向预应力预制板造价高、工艺复杂、耐久性差等难题。
