Plate and column side joint connecting structure, steel pipe concrete plate and column structure and construction method

The invention discloses a plate and column side joint connecting structure, a steel pipe concrete plate and column structure including the plate and column side joint connecting structure and a construction method of the steel pipe concrete plate and column structure, and relates to the field of steel pipe concrete stiffening and mixing structures. The plate and column side joint connecting structure comprises symmetric T-shaped steel supporting plates, multiple first locating steel plate assemblies and multiple first locating sliding block assemblies. Compared with traditional means of anchorbolts, shear reinforcements and the like, the symmetric T-shaped steel supporting plates, the first locating steel plate assemblies and the first locating sliding block assemblies are adopted for cooperating, continuous shear resisting can be achieved, punching resistance of plate and column side joints is greatly improved, and the punching resisting requirement of the plate and column side joints can be met; and meanwhi
