Oriented steel fiber reinforced UHPC (Ultra High Performance Concrete) encircling concrete structure and preparation method thereof
The invention relates to a directional steel fiber reinforced UHPC surrounding concrete structure and a preparation method, and belongs to the technical field of building structures. The directional steel fiber reinforced UHPC enclosure concrete structure comprises an enclosure prepared from directional steel fiber reinforced UHPC, and common concrete poured in the directional steel fiber reinforced UHPC enclosure, the UHPC encircling sleeve reinforced by the oriented steel fibers forms external constraint on the common concrete; the directional steel fiber reinforced UHPC encircling sleeve is of a cylindrical structure. The steel fibers in the UHPC are subjected to circumferential orientation, so that the fiber arrangement direction is kept consistent with the stress direction, and the reinforcing and toughening effects of the steel fibers are fully exerted. In the directional steel fiber reinforced UHPC encircling sleeve, when the arrangement direction of the steel fibers is consistent with the tension direction of the concrete, the steel fibers can effectively improve the tensile property along the direction of the steel fibers.
本发明涉及一种定向钢纤维增强的UHPC围套混凝土结构及制备方法，属于建筑结构技术领域。定向钢纤维增强的UHPC围套混凝土结构，包括由定向钢纤维增强的UHPC制备形成的围套，及浇筑在该定向钢纤维增强的UHPC围套内的普通混凝土；由定向钢纤维增强的UHPC围套对普通混凝土形成外部约束；定向钢纤维增强的UHPC围套为柱形体结构。本发明中将UHPC内部的钢纤维进行环向定向，使纤维排布方向与受力方向保持一致，充分发挥钢纤维的增强、增韧作用。在定向钢纤维增强的UHPC围套中，当钢纤维的排布方向与混凝土受拉力的方向保持一致时，钢纤维能够更有效地提高沿钢纤维方向的抗拉性能。
