PURPOSE: A construction method for a lattice beam is provided to improve construction quality and constructing efficiency, and drastically reduce manufacturing cost. CONSTITUTION: A construction method for a lattice beam includes: a step of installing a mold plate(1); a step of fastening a cylinder mold on the mold plate with plural screws; a step of assembling a cylinder cover on the cylinder mold; a step of installing plural steel reinforcing bars among the cylinder molds; a step of forming a concrete layer by injecting and hardening concrete among the cylinder molds on the upper side of the mold plate; a step of removing the cylinder cover and the screws after the concrete layer is hardened; a step of inserting a division mold plate into the cylinder mold, and then rotating the division mold plate at a certain angle in order to insert the periphery of the division mold plate into latching grooves on the plural side vanes of the cylinder mold; a step of upwardly pulling the division mold plate by using a suspended loop in order to remove the cylinder mold from the concrete layer; and a step of removing the mold plate after curing the concrete layer. [Reference numerals] (AA) Installing a mold plate; (BB) Fixing the position of a cylindrical mold on the mold plate with a plurality of screws; (CC) Assembling a cylinder cover; (DD) Installing steel reinforcing bars; (EE) Injecting concrete; (FF) Removing the cylinder cover and the screws; (GG) Inserting a division mold plate in the cylindrical mold; (HH) Rotating the division mold plate to be inserted and installed inside the cylindrical mold; (II) Pulling up the division mold plate to separate the cylindrical mold; (JJ) Removing the mold plate
