Concealed ladder stand for steel tube towers
The invention relates to special ladder stands for steel tube towers, in particular to a concealed ladder stand for the steel tube towers. A plurality of transverse rods (4) are arranged at intervals between two spaced vertical rods (7) from top to bottom, and the two vertical rods are fixed onto connection flanges (24) at upper and lower ends of a lowest steel tube tower (22) by the aid of upper inner connection rods (1) and lower inner connection rods (15) respectively. A plate (17) is provided with a plurality of projection blocks (9) at intervals, and each projection block (9) fits height and width of a space between each two adjacent transverse rods. Two sides of the lower portion of the plate are in hinged connection with one ends of two lower connection rods (13) respectively, and sleeve rings (19) at the other ends of the two lower connection rods sleeve two sides of a lower round rod (12) respectively. Two sides of the upper portion of the plate are in hinged connection with one end of two upper connection rods (5), and sleeve rings at the other ends of the two upper connection rods sleeve two sides of an upper round rod (2) respectively. By the aid of each projection block filled between each two adjacent transverse rods correspondingly, irrelevant personnel can be prevented from climbing the steel tube towers.
