Prestressed integral seamless terrace
The invention provides a prestressed integral seamless terrace. The prestressed integral seamless terrace comprises a foundation layer, a PE film layer laid on the foundation layer and a concrete layer laid on the PE film layer, the concrete layer comprises concrete and prestressed tendons arranged in the concrete, and a middle cushion layer is further arranged between the PE film layer and the foundation layer. According to the prestressed integral seamless terrace, the prestressed tendons are arranged in the concrete, and after the strength of the concrete meets a design requirement, the prestressed tendons can be tensioned to apply prestressed pressure to the concrete, so that the shrinkage stress of the concrete is solved, the external load effect during normal use of the terrace is resisted, and the problem that the terrace is prone to cracking is effectively solved; meanwhile, through the mode of applying prestress, a terrace cutting seam and a common reinforcing mesh in a traditional terrace can be omitted.
本发明提供一种预应力整体无缝地坪，包括地基层、铺设于所述地基层之上的PE膜层、以及铺设于所述PE膜层之上的混凝土层，所述混凝土层包括混凝土及布置于所述混凝土内的预应力筋，所述PE膜层与所述地基层之间还设有中间垫层。本发明通过在混凝土内布置预应力筋，在混凝土强度达到设计要求后，还可以通过张拉预应力筋来对混凝土施加预应压力，以此来解决混凝土自身收缩应力，并抵抗地坪正常使用期间的外荷载作用，从而有效解决地坪容易开裂的问题；同时，通过施加预应力的方式，可以取消地坪切割缝和传统地坪中的普通钢筋网片。
