Description
Technical Field

background
In the prior assembly type building construction, the joints of the prefabricated concrete beams and columns and the prefabricated concrete beams and columns are connected by adopting a secondary pouring wet method. The method comprises the steps of overlapping the steel bar sections reserved at the end heads of the precast beams and the steel bar sections reserved on the beam joints of the node members, correspondingly binding the adjacent steel bars, then pouring concrete on the overlapped positions of the steel bars on site, and connecting the precast beams and the precast node members into a whole. Although the beam and the node member can be connected into a whole by the connection mode, the concrete poured in the construction site cannot be integrated with the previously solidified concrete on the prefabricated member in the solidification process, and the tensile strength at the interface is low. In addition, the steel bars of the two beam columns at the butt joint part are not directly connected, and the longitudinal force of the beam at the butt joint part is completely balanced by the shearing force between the concrete wrapping the steel bars and the steel bars, so that the stress state of the concrete at the butt joint part is deteriorated. The tensile strength and the bending strength are far lower than those of the prefabricated member. The 'wet method' is used for connecting the precast beam and the precast node member, so that a weak link is generated in the whole building, and the seismic performance of the building is reduced.
