Prefabricated fiber concrete slab structural member
The invention discloses a prefabricated fiber concrete slab structural member. In order to solve the problems that concrete slabs are insufficient in toughness and prone to generating shrinkage cracks, the prefabricated fiber concrete slab structural part comprises a plurality of prefabricated fiber concrete slabs and a plurality of connecting pieces, a plurality of through holes are formed in the upper top surface and the lower bottom surface of the prefabricated fiber concrete slab; the plurality of connecting pieces respectively penetrate through the plurality of through holes and are filled with flat mortar; the prefabricated fiber concrete slab comprises basalt fibers with the volume content being 0.2% and the length being 6 mm. The upper top face and the lower bottom face of the prefabricated fiber concrete slab are both subjected to chiseling treatment and filled with flat mortar. According to the invention, the toughness of the concrete can be improved by doping basalt fibers, and through the design of the through holes and the connecting pieces, a plurality of concrete slabs can be conveniently connected through the prestressed connecting pieces and the flat mortar on a construction site, so that the connection is firm.
本发明公开了一种预制纤维混凝土板结构件。为解决混凝土板韧性不足、容易产生收缩裂缝的问题，本发明的一种预制纤维混凝土板结构件，包括多块预制纤维混凝土板和多个连接件，其中任一预制纤维混凝土板具有长方体形状，且在该预制纤维混凝土板的上顶面和下底面设有多个贯穿孔洞；所述多个连接件分别穿过所述多个贯穿孔洞，并灌入平砂浆；该预制纤维混凝土板包含体积含量为0.2％的且长度为6mm的玄武岩纤维；该预制纤维混凝土板的上顶面和下底面均经过凿毛处理，且灌入平砂浆。本发明通过掺杂玄武岩纤维可提升混凝土韧性，且通过贯穿孔洞和连接件的设计便于在施工现场才需将多块混凝土板通过预应力连接件和平砂浆连接起来，连接牢靠。
