Multi-layer prestressed structure construction technology
The invention relates to the field of building construction, in particular to a multi-layer prestressed structure construction technology which comprises the following construction steps that S1, a Yth floor slab is built, specifically, a formwork supporting system is built; a reinforcing mesh and prestressed tendons are laid on the formwork supporting system; concrete is poured, and the reinforcing mesh and the prestressed tendons are buried in the concrete; s2, after the concrete strength of the Yth layer reaches 1.2 N/mm, the step S1 is repeated till all floors are built; when the concrete strength of the Nth layer of floor slab reaches 80%-100% of the design strength, prestressed tendons of the Nth layer of floor slab are tensioned, N is a positive integer, and the Nth layer of floor slab is the topmost layer of floor slab where the prestressed tendons are not tensioned; anchor sealing is conducted on the prestressed tendons and the floor slabs; and S4, the step S3 is repeated until the prestressed tendons in all the floor slabs are tensioned. The construction method has the effect of shortening the construction period.
本申请涉及一种多层预应力结构施工工艺，涉及建筑施工的领域，其包括如下施工步骤：S1：修建第Y层楼板：搭建模板支撑体系；在模板支撑体系上铺设钢筋网和预应力筋；浇筑混凝土，将钢筋网和预应力筋埋设于混凝土内；S2：待第Y层的混凝土强度达到1.2N/mm²后，重复S1，直至所有楼板修筑完成；S3：预应力施工：待第N层楼板的混凝土强度达到设计强度的80%‑100%，张拉第N层楼板的预应力筋，其中，N为正整数，第N层楼板为所有未张拉预应力筋的最顶层的楼板；对预应力筋和楼板进行封锚；S4：重复S3，直至所有楼板中的预应力筋张拉完成。本申请具有能够缩短施工周期的效果。
