A novel laminated type plate hook includes a plate hook formed by laminating a plurality of layers of steel plates; each layer of steel plate is provided with communicated connection holes, each connection hole is internally provided with a fastener, each fastener passes through the connection hole, two steel plates at the outside are clamped tightly and fixed by the fasteners, two ends of each fastener are each of a round-head shape, and the fasteners are uniformly distributed on the plate hook. When the plurality of steel plates are riveted, the fasteners pass through the connection holes, the two steel plates at the outside are clamped tightly and fixed by the fasteners, welding is avoided when the plate hook is riveted, and welding seaming does not appear at a riveting position, so that the quality of the plate hook can be improved, heat influence and stress concentration cannot be generated at the riveting position, and the plate hook is avoided from generating deformation in the process.
