UHPC (Ultra High Performance Concrete) curtain wall plate
The invention discloses a UHPC (Ultra High Performance Concrete) curtain wall plate, which belongs to the field of building materials and is novel and reasonable in structure, a novel PR-UHPC curtain wall plate is formed by pre-embedding a pre-stressed part consisting of a pre-stressed tendon and a sleeve into a UHPC base plate, the ultrahigh compressive property of UHPC and the high tensile property of the pre-stressed tendon are fully utilized, and the service life of the UHPC curtain wall plate is prolonged. A reinforcing and toughening system is formed in the UHPC base plate, the bending resistance of the UHPC curtain wall plate is improved on the basis that the weight of the plate is slightly increased, the tail ends of the sleeves in part of or all the prestress pieces penetrate through the back face of the UHPC base plate, installation of the UHPC curtain wall plate can be achieved without matching of an extra frame body on the back face of the UHPC base plate, and the installation cost is reduced. Compared with the prior art, use of an aluminum alloy or steel frame structure on the back face of the UHPC panel is simplified, and the problems of cracking, deformation and the like of an existing UHPC curtain wall plate are solved.
本发明公开一种UHPC幕墙板，属于建筑材料领域，结构新颖合理，通过将由预应力筋和套筒组合成的预应力件预埋入UHPC基板中，从而形成一种新型预应力超高性能混凝土(PR‑UHPC)幕墙板，其不仅充分利用了UHPC的超高抗压性能和预应力筋的高抗拉性能，在UHPC基板内部形成了增强、增韧体系，在较少增加板材重量的基础上，提高了UHPC幕墙板的抗弯性能，而且通过将部分或全部预应力件中的套筒尾端贯穿UHPC基板的背面布置，无需再在UHPC基板背面搭配额外的架体即可实现UHPC幕墙板的安装，相比现有技术简化了UHPC面板背面的铝合金或钢质框架结构的使用，一并解决了目前UHPC幕墙板的开裂和变形等问题。
