Transverse segmental prefabricated prestressed concrete bent cap structure and assembling method thereof
The invention discloses a transverse segmental prefabricated prestressed concrete bent cap structure and an assembling method thereof. The transverse segmental prefabricated prestressed concrete bentcap structure comprises a bent cap body and prefabricated stand columns. The bent cap body comprises a plurality of prefabricated sections spliced in the transverse direction; a hole through which a steel strand penetrates is reserved in each prefabricated section; every two adjacent prefabricated sections are connected through a wet joint section; an upper profile steel lap joint structure and alower profile steel lap joint structure which are matched with each other are pre-buried in the joint surfaces, close to the two sides of the wet joint section, of every two adjacent prefabricated sections respectively; the transverse steel bars on the top face, the bottom face and the vertical face of each prefabricated section extend into the range of the corresponding wet joint section, and thetransverse steel bars of each prefabricated section and the transverse steel bars of another adjacent prefabricated section are arranged in a staggered lap joint mode. The small-tonnage segmented prefabricated assembly of the large-volume prestressed concrete bent cap is achieved, stress of the bent cap structure can be better ensured, the structure quality is improved, and the construction speedis increased.
本发明公开了横向分段预制装配预应力混凝土盖梁构造及拼装方法，包括盖梁主体和预制立柱；盖梁主体包括若干沿横向拼接的预制节段；每一预制节段均预留穿钢绞线的孔洞；每两个相邻的预制节段间通过湿接缝段连接；每两段相邻的预制节段靠近湿接缝段两侧的接缝面均分别预埋有相匹配的上型钢搭接构造和下型钢搭接构造；每一预制节段的顶面、底面和立面的若干横向钢筋均伸出至相应的湿接缝段范围内，且每一预制节段的若干横向钢筋与相邻的另一预制节段的若干横向钢筋互相交错搭接布置。本发明实现大体量预应力混凝土盖梁的小吨位分段预制装配，能够更好地确保了盖梁结构的受力，提高结构质量、加快施工速度。
