PROBLEM TO BE SOLVED: To enable an operator to perform the coupling operation of a support post with a horizontal rail by oneself by temporarily placing a panel in a stable state between support posts. ! SOLUTION: In a construction method of a guard fence (1), a panel has a pair of upper and lower horizontal rails (21) and a plurality of vertical rails (22) bridged between both horizontal rails, and a bracket is mounted on a support post such that the outer peripheral part of the support post is surrounded, and formed with a support post mounting part (31) partially having a missing part (31a) and a pair of horizontal rail coupling parts (32) extended from both ends of the support post mounting part for coupling the horizontal rails. The construction method of the guard fence (1) includes the steps of: mounting the support post mounting part of the bracket on the support post; mounting a fixture (40) for construction on both horizontal rail coupling parts to prevent the opening of both horizontal rail cou |
