Abstract

A ladder used for a building structure includes a main member, a secondary member, a connecting rod and a fixing rod. The main member includes a plurality of horizontal rungs, a pair of first rails symmetrically fixed with two opposite ends of the horizontal rung, and a 5 groove formed at a side of the first rail. The secondary member also includes a plurality of horizontal rungs and a pair of second rails symmetrically fixed with two opposite ends of the horizontal rung. The amount of the horizontal rung is measured according to actual usage of the height of the ladder. The second rail includes a fixing block formed on its bottom at a side near the main member to fix with the groove. One end of the connecting rod is rotatably 10 connected with the bottom of the first rail, and the other end of the connecting rod is slidably connected with the bottom of the second rail. One portion of the fixing rod is hinged with the top of the first rail, and the other portion can be clamped with the top of the second rail. The structure of the present disclosure can be optionally exchanged between a herringbone ladder and a linear ladder, and have a good structural strength while obtaining a higher height than an 15 original height of the herringbone ladder when it is exchanged as the linear ladder.
