Variable-cross-section complex special-shaped prestressed stair beam-slab integrated component and manufacturing method thereof
The invention discloses a variable cross-section complex special-shaped prestressed stair beam and slab integrated component and a manufacturing method thereof.The integrated component comprises a prestressed beam, a high-side wing plate, a low-side wing plate and prestressed tendons, the high-side wing plate and the low-side wing plate are arranged on the two sides of the prestressed beam respectively, and the cross-sectional area of the prestressed beam is gradually increased in the length direction of the prestressed beam; one ends of the prestressed tendons are anchored in the prestressed beam, the other ends of the prestressed tendons extend out of the beam end and then are tensioned and anchored in the cast-in-place connecting section between the two components, and the number of the prestressed tendons is gradually reduced in the direction from the tensioning end to the cantilever end; the manufacturing method comprises the following steps that firstly, the adjustable pouring mold is installed; secondly, embedded parts are installed, prestressed tendons are laid, and beam steel bars are bound; thirdly, UHPC slurry is poured; 4, maintaining the components; and fifthly, the component is demolded. On the premise that the structural bearing requirement is met, the using amount of steel bars and the requirement for concrete anchoring space are reduced, and the lightweight design of the component is achieved.
本发明公开了一种变截面复杂异形预应力楼梯梁板一体化构件及其制作方法，所述一体化构件包括预应力梁、高边翼板、低边翼板、预应力筋，高边翼板、低边翼板分别设置于预应力梁两侧，预应力梁的截面面积沿其长度方向逐渐增大，所述预应力筋的一端锚固于预应力梁的内部，另一端伸出梁端后张拉锚固于两个构件之间的现浇连接段中，沿张拉端至悬挑端的方向预应力筋的数量逐渐减少；其制作方法包括以下步骤：步骤一、安装可调型浇筑模具；步骤二、安装预埋件、敷设预应力筋、绑扎梁钢筋；步骤三、浇筑UHPC浆料；步骤四、构件养护；步骤五、构件脱模。本发明在满足结构承载需求的前提下，减少钢筋用量及对混凝土锚固空间的需求，实现构件轻量化设计。
