Problems solved by technology
The herringbone ladder is generally composed of two ladder frames that can rotate relative to each other. It can be folded, occupies a small area, is easy to store, is light in weight, and is easy to move. It can be used. In addition, when part of the bottom surface cannot meet the conditions for unfolding the ladder, the ladder can be folded into a ladder for use. However, most of the ladders that can form a ladder on the market are maintained The height of the original herringbone, even if it exceeds the original height, the fixing effect is not very good

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] See attached figure 1 - attached Figure 7 , the invention discloses a ladder for construction engineering, comprising a main ladder 1, an auxiliary ladder 2, a fixed rod 4 and a connecting rod 5, the main ladder 1 includes a plurality of ladder rods 3 and first support rods symmetrically fixed at both ends of the ladder rods 3 11. There is a dark groove 111 on one side of the first support rod 11, and the auxiliary ladder 2 includes a plurality of lad...

A ladder for construction engineering, comprising a main ladder (1), an auxiliary ladder (2), connecting bars (5), and fixed bars (4). The main ladder (1) comprises a plurality of ladder bars (3) and first support bars (11) symmetrically fixed at two ends of the ladder bars (3). One side of each first support bar (11) is provided with a hidden groove (111). The auxiliary ladder (2) comprises a plurality of ladder bars (3) and second support bars (21) symmetrically fixed at two ends of the ladder bars (3), wherein the number of ladder bars (3) is measured by the actually used height of a step ladder. The bottom ends of the second support bars (21) at one side close to the main ladder (1) are provided with fixed blocks (211). The fixed blocks (211) may be fixedly connected to the hidden grooves (111). One end of each connecting bar (5) is rotatably connected to the lower end of each first support bar (11), and the other end is slidably connected to the lower end of each second support bar (21). One end of each fixed bar (4) is hinged with the top end of each first support bar (11), and the other end may be clamped to the top end of each second support bar (21). In general, the ladder for construction engineering may be interchanged between a step ladder and an I-shaped ladder, and when switching to the I-shaped ladder, the ladder has good structural strength while obtaining a height that is higher than the step ladder.
Description
technical field [0001] The invention relates to the technical field of herringbone ladders, in particular to a ladder for construction engineering. Background technique [0002] Herringbone ladder: A kind of climbing tool used for decoration and other work in the space above the plane. Because when in use, the front and rear ladder rods and the ground form an isosceles triangle, which looks like a "person" character, so it is called "herringbone ladder". The herringbone ladder is generally composed of two ladder frames that can rotate relative to each other. It can be folded, occupies a small area, is easy to store, is light in weight, and is easy to move. It can be used. In addition, when part of the bottom surface cannot meet the conditions for unfolding the ladder, the ladder can be folded into a ladder for use. However, most of the ladders that can form a ladder on the market are maintained When the height of the original herringbone is exceeded, even if it exceeds the...
