The invention discloses a bent groove-shaped steel plate type laminate member which comprises a base plate and concrete ribs, wherein a steel plate is arranged on the base plate; the bottom of the steel plate in a height direction is embedded in the base plate; the top of the steel plate in the height direction is embedded in the concrete ribs; the steel plate is bent in a length direction to form a number of grooves; opening directions of every two adjacent grooves are opposite; a number of through holes are formed in the middle of the steel plate. The base plate of the laminate member provided by the invention can be equal to smaller than 30 mm; the weight of the laminate member is reduced by 50% or higher while achieving excellent supporting, compression resistance and other conditions and properties; the weights of beams, columns, walls and foundation members are reduced; the clear height of each building storey is increased; the bent groove-shaped steel plate type laminate member provided by the invention further has advantages of being high in overall strength, good in fastness and free of distortion, and improves the quality of buildings.
