The precast concrete post concatenation node, the section of post angle connecting piece is the L type, the section of post limit connecting piece is the II type.
The prefabricated concrete column splicing node is characterized in that the cross section profiles of the column corner connecting piece and the column edge connecting piece are consistent with the cross section size of a lap joint groove formed after the prefabricated concrete upper column is in butt joint with the prefabricated concrete lower column.
The height of the column corner connecting piece and the column edge connecting piece is equal to the height of a lap joint groove formed after the precast concrete upper column is in butt joint with the precast concrete lower column.
Has the advantages that: the invention provides a prefabricated concrete column splicing node which is simple in structure, few in accessories, convenient and fast to assemble and reliable in performance. The assembly between the precast concrete upper and lower columns only needs the fastening operation of the nuts, and the prefabricated concrete columns, the connecting pieces and other accessories are prefabricated in a factory, so that the construction is rapid and the overall performance is reliable. Based on the advantages, the precast concrete column splicing node has a good application prospect.
