Prefabricated UHPC prestressed plate component and prefabrication process thereof
The invention relates to the technical field of highway traffic and buildings, in particular to a UHPC prefabricated slab component which is formed by pouring a UHPC material. Fibers doped in the UHPC material used by the UHPC prefabricated slab component are steel fibers or other fibers with high elastic modulus; the particle size of aggregate used by the UHPC material used by the UHPC prefabricated slab component is 0-1 mm; steel wires of the UHPC prefabricated slab components are tensioned by adopting a pre-tensioning method; the diameter of the steel wires of the UHPC prefabricated slab type components is 1 mm-5 mm, and the distance between the steel wires is 1 cm-10 cm. The plate thickness of the UHPC prefabricated plate component is 3-10 cm, prestress is applied to the steel bars, so that the bending and tensile resistance of the UHPC is improved, the bending and tensile strength of the UHPC plate component is enhanced, and the UHPC prestressed plate component has the advantages of ultrahigh mechanical property and ultrahigh durability of the UHPC, also has ultrahigh bending and tensile strength, integrates the advantages of the UHPC and a prestressed structure, and has the advantages of being simple in structure, low in cost and high in practicability. And the performance is more outstanding.
本发明涉及公路交通及建筑技术领域，具体为一种UHPC预制板类构件，所述UHPC预制板类构件由UHPC材料浇筑而成；所述UHPC预制板类构件所用UHPC材料掺加的纤维为钢纤维或其他高弹性模量纤维；所述UHPC预制板类构件所用UHPC材料所用骨料粒径为0mm‑1mm；所述UHPC预制板类构件采用先张法对钢丝进行张拉；所述UHPC预制板类构件钢丝直径为1mm‑5mm,间距为1cm‑10cm；所述UHPC预制板类构件板厚为3mm‑10cm，通过对钢筋加持预应力，使UHPC的抗弯拉性能得以提高，增强了UHPC板类构件抗弯拉强度，UHPC预应力板类构件不仅具有UHPC超高力学性能，超高耐久性能的优势，也具备超高的抗弯拉强度，集UHPC和预应力结构优点于一身，性能更加突出。
