PURPOSE: A prefabricated timbering for construction is provided to prevent collapse by maintaining enough intensity with a simple structure, and reduce product cost by producing in quantity. CONSTITUTION: A prefabricated timbering for construction is composed of a vertical member(a), horizontal members(b), each coupling plate(1), brackets(2), and wedge pieces(3). A central groove(11) in which the vertical member is inserted is formed in the center of the coupling plate. A plurality of coupling grooves(12) in which the wedge pieces are coupled are formed near the central groove of the coupling plate. A fitting portion(21) in which the coupling plate is coupled is formed in one side of the bracket. A mounting guide(22) in which the vertical member is settled is formed on the upper and lower ends of the fitting portion. A fastening portion(23) in which the horizontal members are coupled is formed on the other side of the brackets. An upper fitting groove(24) and a lower fitting groove(25) in which the wedge pieces are inserted are formed on the upper and lower parts of the brackets. A head portion(31) is formed in right angle direction on the top end of the wedge pieces. A hanging projection(32) of a rivet shape and an outward projecting portion(33) are formed on the bottom part of the wedge pieces.
