Reinforcing structure of ladder
According to the prevention, a structure for reinforcing a ladder includes: a pair of vertical frames spaced apart from each other to be in parallel with each other from side to side to support a load; one or more horizontal supports which are installed between the vertical frames and on which a worker can step and climb; first brackets installed on lower portions of the horizontal supports; diagonal reinforcing members of which one end is connected to the first brackets and which are installed to be rotatable; and second brackets installed to be rotatable with the other end of the diagonal reinforcing members and connected to lower ends of the horizontal supports. Therefore, the structure for reinforcing a ladder can reinforce the horizontal supports of the ladder in a diagonal direction.
