Preparation method of fireproof anti-cracking ultra-high performance concrete beam
The invention belongs to the technical field of constructional engineering application, and particularly relates to a preparation method of a fireproof anti-cracking ultra-high performance concrete beam. Comprising a concrete beam body and a steel bar net rack arranged on the concrete beam body, and the steel bar net rack comprises steel bar net rings arranged in the long edge direction of the concrete beam body at intervals, and transverse steel bars and longitudinal steel bars arranged in the steel bar net rings; the concrete beam body comprises a mixed cement part and an ultra-high-performance concrete part wrapping the mixed cement part, the structure of an existing ultra-high-performance concrete beam is improved, the ultra-high-performance concrete wrapping the steel bar net rack is doped with the foaming cement, the closed-cell characteristic of the foaming cement is utilized, and the foaming cement is added into the ultra-high-performance concrete; and the whole heat conduction system is lowered, so that the internal temperature is controlled, the influence of a fire house on the heat conduction system is reduced, and the purpose of prolonging the service life is achieved.
本发明属于建筑工程应用技术领域，尤其涉及一种防火抗裂化超高性能混凝土梁的制备方法。包括混凝土梁本体以及设置在混凝土梁本体的钢筋网架，所述钢筋网架包括沿混凝土梁本体长边方向间隔设置的钢筋网圈以及设置在钢筋网圈内的横向钢筋和纵向钢筋，所述混凝土梁本体包括混合水泥部以及包裹在混合水泥部外的超高性能混凝土部，本发明通过对现有的超高性能混凝土梁的结构进行改进，使其包裹钢筋网架的超高性能混凝土内掺杂发泡水泥，利用发泡水泥的闭孔的特性，降低整体的导热系统，进而使其内部温度得到控制，从而降低火宅对其的影响，达到提高使用寿命的目的。
