The invention relates to a jointing construction method of concrete construction joints. The method comprises steps of construction of a lower concrete structure and construction of an upper concrete structure, wherein when concrete pouring is performed on the lower concrete structure, the construction joints are reserved according to process, normal height or standard requirements; before initial setting of concrete of the lower concrete structure, coarse aggregates are inserted into the upper surface of concrete which has been poured; a layer of plain cement slurry or an interfacial agent is applied to the surface of the concrete with the aggregates inserted, and the upper concrete structure is poured. According to the jointing construction method of the concrete construction joints, manual or mechanical secondary scabbling is not required, the construction cost is reduced, and the construction efficiency is improved; water is saved, noise is reduced, dust pollution is reduced, and environmental protection
