Abstract

The invention relates to a composite material ladder which is composed of vertical rods and transversal rods both being made from a composite material. The vertical rods and the transversal rods each include a rod-like core part, which is coated with an axial reinforcing layer and a circumferential reinforcing layer. The reinforcing layers are formed by wrapping the core parts with high-strength fibers and coating the fibers with resin, wherein the fibers and the resin are integrated through heat curing. Two joint parts are arranged on two ends of each transversal rod. A plurality of connection plates are arranged on periphery of each vertical rod. The joint parts are connected to the connection plates through bolts to form a main body of the ladder. The ladder has high strength and light weight, and is convenient to move and use.

Description

technical field [0001] The present invention relates to a lightweight composite ladder. Background technique [0002] Ladders are a common tool. At present, lighter ladders are made of aluminum alloy or wooden ladders, but they are still heavy and not very convenient to carry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite material ladder which has the advantages of high strength and light weight. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A ladder made of composite material comprises two parallel vertical bars arranged vertically, and a plurality of cross bars are arranged between the two vertical bars. The joint part of the joint part, and the T-shaped transverse part of the joint part is close to the core part, and the T-shaped vertical part is provided with at least two bolt holes, and also includes an axial reinforcement layer,...
