Directional fiber reinforced concrete-RC composite beam construction method and composite beam
The invention relates to an oriented fiber reinforced concrete-RC composite beam construction method and a composite beam, and belongs to the technical field of concrete beams. The method comprises the steps that oriented fiber reinforced concrete is poured, groove-shaped steel bars are pre-buried, and a uniform magnetic field is applied to form a tension area in the RC composite beam; common concrete is continuously poured on the oriented fiber reinforced concrete poured and formed in the tensile area through the shaping mold; and the common concrete and the stirrup embedded part form a pressed area of the composite beam. A tension area of the composite beam is made of oriented fiber reinforced concrete, and a compression area of the beam is made of common concrete. Through calculation and optimization, the directional fiber reinforced concrete-RC composite beam has excellent working performance and economical efficiency, and cracking of the directional fiber reinforced concrete can be greatly reduced.
本发明涉及定向纤维增强混凝土‑RC组合梁施工方法及组合梁，属于混凝土梁技术领域。该方法分为：浇筑定向纤维增强混凝土，并预埋槽形钢筋，施加均匀磁场形成RC组合梁中的受拉区；在受拉区浇筑成型的定向纤维增强混凝土上利用定型模具继续浇筑普通混凝土；普通混凝土与箍筋预埋件形成组合梁的受压区。本组合梁的受拉区为定向纤维增强混凝土，梁的受压区为普通混凝土。通过计算和优化，定向纤维增强混凝土‑RC组合梁具有优异的工作性能和经济性，而且定向纤维增强混凝土可以大大减小混凝土的开裂。
