Ultra-high performance concrete and common concrete composite beam and construction method thereof
The invention provides an ultra-high-performance concrete and common concrete composite beam and a construction method thereof.The ultra-high-performance concrete and common concrete composite beam comprises a composite beam body, the composite beam body is formed by pouring ultra-high-performance concrete and common concrete materials, the ultra-high-performance concrete is located on the lower edge of the middle portion of the composite beam body, and the common concrete is located on the lower edge of the middle portion of the composite beam body; the common concrete is poured at the top and two ends of the ultra-high performance concrete. Common concrete is used for parts without tensile stress or with small tensile stress, ultra-high performance concrete is located at the lower edge of the middle beam bottom with large tensile stress, the advantages of the two materials can be fully played, and the tensile stress state of the beam bottom is improved; the toughness and tensile strength of the ultra-high performance concrete can prevent the beam body from cracking, enhance the durability of the structure and prolong the service life of the structure; the composite material beam body does not generate cracks, so that the real rigidity of the composite material beam body is not reduced, the structural stress is improved, and the deformation is smaller during use.
本发明提供了一种超高性能混凝土与普通混凝土复合梁及其施工方法，包括复合材料梁体，所述复合材料梁体采用超高性能混凝土和普通混凝土材料浇注而成，所述超高性能混凝土位于所述复合材料梁体的中间部分的下缘，所述普通混凝土浇筑于所述超高性能混凝土的顶部和两端。本发明将普通混凝土用于没有拉应力或拉应力很小的部位，超高性能混凝土位于拉应力较大的中部梁底下缘，能充分发挥两种材料的优点，改善梁底拉应力状态；超高性能混凝土韧性和抗拉强度可以避免梁体开裂，增强结构耐久性，延长结构的使用寿命；由于复合材料梁体不产生裂缝可以使得其真实刚度不减小，有助于改善结构受力，使用时的变形更小。
