PROBLEM TO BE SOLVED: To provide a beam insulation structure in a simple structure which insulates a horizontal beam hung with an electric conductor without a clearance and is easily positioned/attached uniformly at mounting. SOLUTION: The beam insulation structure for insulating the horizontal beam 2 includes a pair of insulation support units 50 having one end attached to the flange-like member 2a of the horizontal beam 2 and the other end for clamping the electric conductor 1 and hanging the two electric conductors 1 in parallel; a pair of mounting fittings 40 mounted to the flange-like member 2a and making the pair of insulation support units 50 detachable respectively; and an insulation cover 30 having a flat plate-like shape fitted to the flange-like member 2a in which lips 12, 22 of a cross section groove-like form at an opposite side position are engaged with the opposite side position of the flange-like member 2a to cover it and ends abutted on a pair of parts are mounted without a clearance. The insulation cover 30 integrally includes opening holes 16, 26 for penetrating the insulation support units 50; covering parts 14, 24 for fitting the mounting fittings 40 into the peripheries of the opening holes; and a superposed part A in which the ends abutted on the pair of parts are superposed.
