The invention relates to the technical field of large-span concrete slabs, in particular to a large-span pipe truss prestressed concrete slab which comprises a concrete slab, transverse/vertical load-bearing steel bars, a pipe truss and spiral rib stress relief steel wires. The spiral rib stress relieving steel wires are arranged on the concrete slabs and are used for solving the problem that the concrete slabs crack in the stacking, transporting and installing processes of the concrete slabs; the stress effect of the concrete slab can be further enhanced by adding the spiral rib stress relieving steel wires, the laying direction of the spiral rib stress relieving steel wires is in the length direction of the concrete slab, and compared with single stress steel bars, the problem that the concrete slab cracks in the stacking, transporting and installing processes is solved; therefore, the probability of cracking of the concrete slab is reduced.
本发明涉及大跨度混凝土板技术领域，更具体地说是一种大跨度管桁架预应力混凝土板，包括：混凝土板、横向/竖向受力钢筋、管桁架和螺旋肋消除应力钢丝，所述管桁架设置在所述混凝土板上，所述螺旋肋消除应力钢丝设置在所述混凝土板上，所述螺旋肋消除应力钢丝用于解决所述混凝土板的堆码、运输、安装过程中混凝土板开裂问题；本发明通过增加螺旋肋消除应力钢丝能够进一步增强混凝土板的受力效果，螺旋肋消除应力钢丝的铺设方向沿着混凝土板的长度方向，相对于采用单一的受力钢筋防止混凝土板堆码、运输、安装过程中出现开裂的问题，从而降低了混凝土板出现开裂的概率。
