Novel fabricated main beam and secondary beam connecting joint and construction method
The invention relates to a novel fabricated main beam and secondary beam connecting joint and a construction method. The novel fabricated main beam and secondary beam connecting joint comprises a left side secondary beam, a right side secondary beam and a main beam. A reversed L-shaped lower clamping block is arranged at one end of the left side secondary beam, a first bent steel bar matched with the lower clamping block in shape is pre-buried in the left side secondary beam, an inverted L-shaped upper clamping block is arranged at one end of the right side secondary beam, a second bent steel bar matched with the upper clamping block in shape is pre-buried in the right side secondary beam, and the upper clamping block is buckled with the lower clamping block. One end of the first bent steel bar penetrates through the lower clamping block and is connected with a nut in a screwed mode, and one end of the second bent steel bar penetrates through the upper clamping block and is connected with a nut in a screwed mode. A groove is formed in the middle of the front face of the main beam, two grouting square holes are formed in the two sides of the groove in a staggered mode, the upper clamping block and the lower clamping block are buckled into the groove together, the nuts are located in the corresponding grouting square holes, and the grouting square holes are filled with filling materials. The advantages of a fabricated structure are reflected to a greater extent, the assembly efficiency is improved, the field workload is reduced, and the construction period is shortened.
本发明涉及一种新型装配式主、次梁连接节点及施工方法，包括左侧次梁、右侧次梁和主梁，左侧次梁一端设有呈“┛”形的下卡块，左侧次梁内部预埋有与下卡块形状配合的第一弯折钢筋，右侧次梁一端设有呈“┏”形的上卡块，右侧次梁内部预埋有与上卡块形状配合的第二弯折钢筋，上卡块与下卡块扣接，第一弯折钢筋的一端贯穿下卡块并旋接有螺母，第二弯折钢筋的一端贯穿上卡块并旋接有螺母，主梁正面的中部开设有沟槽，沟槽的两侧错位开设有两个灌浆方孔，上卡块与下卡块一起扣入到沟槽内，螺母位于对应的灌浆方孔内，灌浆方孔内通过填充材料填充。本发明更大程度的体现出装配式结构的优点，提高了装配效率，减少了现场的作业量，缩短了施工工期。
