The invention relates to a PEC
beam column and column-column connecting
system capable of achieving efficient pouring and
butt joint, bracket web inserting grooves with upward openings are formed in the ends, away from a PEC column, of brackets, PEC beam webs at the two ends of a PEC beam are inserted into the bracket web inserting grooves of the brackets on the two sides correspondingly, and U-shaped
steel plates serve as steel molds of a column-column post-pouring belt and a
beam column post-pouring belt; and the reinforcing ribs are inserted between the upper PEC column and the lower PEC column and between the bracket and the
flange of the PEC beam. The method has the beneficial effects that
butt joint is conducted at the
butt joint position of the PEC beam and the bracket in a web slot mode, the butt joint efficiency is improved, the positioning difficulty in
beam column butt joint is low, the needed positioning time is shortened compared with traditional positioning, the construction
workload is greatly reduced, the connection accuracy and stability of the PEC beam and the bracket are directly guaranteed after
insertion, and the construction efficiency is improved. Subsequent installation of the U-shaped steel plate is facilitated; and in the post-cast strip pouring aspect, formwork erecting and disassembling steps are not needed, the construction process is
environmentally friendly, the construction time is greatly saved, and material waste is effectively avoided.
