Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Composite ladder, including the montant of two parallel vertical layouts, is provided with many cross bars between two montants,
It is T-shaped connector portions 11 that described cross bar includes that shaft-like core 1, core 1 two ends are provided with cross section, and connector portions 11T font
Lateral part near core 1, T-shaped vertical section is provided with at least two bolt hole 111, also includes axial enhancement Layer 2,
Described axial enhancement Layer 2 is wound around along core 1 length direction by high-intensity fiber, and wraps the T-shaped lateral part of connector portions 11,
And coating resin be heating and curing after formed；The axially outside circumference enhancement Layer 3 that is provided with of enhancement Layer 2, described circumference enhancement Layer 3 is by height
Strong fiber is circumferentially wound along core 1, and coating resin be heating and curing after formed；
Described montant includes that shaft-like core, core outer layer are provided with axial enhancement Layer, is provided with outside axial enhancement Layer
Circumference enhancement Layer, axial enhancement Layer by high-intensity fiber along core length direction be wound around, and coating resin be heating and curing after formed；Institute
State circumference enhancement Layer circumferentially wound along core by high-intensity fiber, and coating resin be heating and curing after formed, montant circumference reinforcement
The outer connecting plate 4 being additionally provided with L-shaped of layer, described connecting plate 4 is wound around by high-intensity fiber and is bundled in circumference enhancement Layer side face, and is coated with
Cloth resin forms one, connecting plate 4 specular of two montants after being heating and curing；The connector portions 11 at described cross bar two ends is respectively
It is connected with connecting plate 4 bolt of two montants；
Described core is polystyrene foam, described high-intensity fiber be glass fibre, polyester fiber, nylon fiber, poly-third
Alkene fiber or polyimide fiber, described resin is epoxy resin, phenolic resin, polyimide resin or BMI tree
Fat.
As it is shown in figure 1, be the part-structure schematic diagram of ladder, both sides vertical for montant, middle for cross bar as upper
The pedal of lower ladder.
Vertical and cross bar is composite, and inside is core 1, and core 1 is polystyrene foam, very light weight.Core 1
The outer high-intensity fiber of compact winding the most along its length forms axial enhancement Layer 2, and all fibres is wrapped up by coating resin, adds
Form entirety after heat cure, in like manner, also form circumference enhancement Layer 3 at the axial outer circumferentially wound high-intensity fiber of enhancement Layer 2 and be coated with
All fibres is wrapped up by cloth resin, forms entirety after being heating and curing.
