Directional metal fiber reinforced butterfly-shaped concrete plate and preparation method thereof
The invention relates to a directional metal fiber reinforced butterfly-shaped concrete slab and a preparation method, the directional metal fiber reinforced butterfly-shaped concrete slab comprises a concrete slab main body, two sides of the concrete slab main body are inwards and oppositely concaved to form arc-shaped grooves, so that the concrete slab main body is in a butterfly shape; the middles of the two arc-shaped grooves extend in the tangential direction of the arc-shaped grooves to separate a parallelogram-like tension-compression mixed stress area and two main pressure stress areas with trapezoid-like opposite angles in the concrete slab body area, and the tension-compression mixed stress area and the main pressure stress areas are formed through pouring of concrete doped with metal fibers. The metal fibers in the tension-compression mixed stress area are directionally distributed in a consistent direction after a directional magnetic field is applied, the metal fibers in the main pressure stress area are distributed in a disordered direction, the structural design is reasonable, industrial production can be achieved, and the production efficiency is improved. The method has the advantages of being convenient to construct, reducing structural dead weight, improving structural size precision and quality and reducing the steel bar consumption of the structure.
本发明涉及一种定向金属纤维增强的蝶形混凝土板及制备方法，包括混凝土板主体，所述混凝土板主体两侧朝内相向内凹有弧形槽以使混凝土板主体呈蝶形，两弧形槽中部沿其切线方向延伸将混凝土板主体区中呈类平行四边形的拉压混合受力区以及两对角呈类梯形的主压受力区分隔，所述拉压混合受力区与主压受力区内均经掺有金属纤维的混凝土浇筑成型；所述拉压混合受力区内的金属纤维经施加定向磁场呈朝向一致的定向分布，所述主压受力区内的金属纤维呈乱向分布，该结构设计合理，可实现工业化生产，具有施工方便、减轻结构自重、提高结构尺寸精度和质量、减少结构的钢筋用量的优势。
