Prefabricated prestressed reinforced concrete folding beam and construction method thereof
The invention discloses a prefabricated prestressed reinforced concrete folding beam and a construction method thereof. The prefabricated prestressed reinforced concrete folding beam comprises a first prefabricated straight beam and a second prefabricated straight beam which are inclined, and the upper end of the first prefabricated straight beam and the upper end of the second prefabricated straight beam are in butt joint to form an inverted V shape; prestressed tensioning through holes are reserved in the first prefabricated straight beam and the second prefabricated straight beam in the length direction of the first prefabricated straight beam and the second prefabricated straight beam; and bent prestressed cables penetrate into the prestressed tensioning through holes of the first prefabricated straight beam and the second prefabricated straight beam. The use amount of molds can be effectively saved, mold machining is simpler, the construction procedure is simple, operation is convenient, the construction period and labor force are saved, the safety and stability of joints at the bending position of the bent beam can be effectively guaranteed, and comprehensive development of the fabricated technology is promoted.
本发明公开一种用于预制预应力钢筋混凝土折梁及其施工方法，包括倾斜的第一预制直梁和第二预制直梁，第一预制直梁和第二预制直梁的上端对接连接构成倒V型；第一预制直梁和第二预制直梁内沿其长度方向预留有预应力张拉通孔；第一预制直梁和第二预制直梁的预应力张拉通孔内穿入有弯折的预应力索；其能有效节省模具用量，使模具加工更简单，其施工工序简单，便于操作，节省工期和劳动力，能有效保证折梁弯折处节点的安全性和稳定性，推动装配式技术的全面发展。
