Prestressed reinforcement reinforcing system used for dome ring beam and construction method of prestressed reinforcement reinforcing system
The invention discloses a prestressed reinforcement reinforcing system used for a dome ring beam and a construction method of the prestressed reinforcement reinforcing system. The prestressed reinforcement reinforcing system comprises an upper layer of prestressed tension structure and a lower layer of prestressed tension structure, and each layer of prestressed tension structure comprises at least one set of prestressed reinforcements. Each set of prestressed reinforcements comprises four prestressed reinforcements which are uniformly distributed in an annular array manner, and each prestressed reinforcement is horizontally arranged in the radial direction of the dome ring beam. All the prestressed reinforcements of each layer of prestressed tension structure are uniformly distributed inthe annular array manner. One ends of the prestressed reinforcements are anchored to the dome ring beam, and the other ends of the prestressed reinforcements are anchored to annular connecting pieces.The construction method comprises the steps of grouping, penetrating and anchoring the prestressed reinforcements on each layer and tensioning the prestressed tension structures on the upper layer and the lower layer in a layered manner. According to the system, the problem that connection of the dome ring beam and a wall body is prone to deforming in the related technology is solved, concrete cracks generated at the joint of the dome ring beam and the wall body are reduced, and therefore the bearing capacity of the reinforced concrete structure is improved.
本发明公开了一种用于穹顶环梁的预应力钢筋增强体系及其施工方法。所述预应力钢筋增强体系包括上、下两层的预应力张拉结构，每层预应力张拉结构包括至少一组预应力筋；每组预应力筋包括四根呈环形阵列均匀分布的预应力筋，每根预应力筋沿穹顶环梁的径向水平设置；每层预应力张拉结构的所有预应力筋呈环形阵列均匀分布；预应力筋的一端锚固于穹顶环梁，另一端锚固于环形连接件；施工方法包括每层预应力筋分组穿束、锚固以及上、下两层的预应力张拉结构分层张拉的方式。本发明解决相关技术中穹顶环梁与墙体连接易出现变形的情况，减少穹顶环梁与墙体连接处混凝土裂缝的产生，从而提高钢筋混凝土结构的承载能力。
