Description

Technical Field

[0001] The present invention relates to a processing technology of bamboo, and particularly to a method for making a bamboo ladder with anti-corrosion, anti-moth and anti-cracking properties for bamboo. Background Art

[0002] As the most basic climbing tool for communication, electricity and daily construction, the commonly used bamboo ladders are prone to cracking, rotting, and their durability and safety are greatly reduced. For example, ladders made of fiberglass are insulated but very heavy and inconvenient to carry. Although aluminum alloy ladders are light and have high strength, they are not insulated, and the use of metal ladders is generally prohibited in general construction, with many potential safety hazards. Aramid fiber, also known as (Kevlar fiber), is a material for making bulletproof products, with excellent tensile strength. Its tensile strength is 5 times that of steel wire of the same weight, and it is insulated and fireproof. Using resin glue as an adhesive to make a bamboo ladder of bamboo composite material can increase the strength, safety and durability of the bamboo ladder. In summary, the superiority, lightness and insulation of the bamboo ladder made of aramid fiber composite material are irreplaceable by other materials. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a method for making a bamboo ladder with anti-corrosion, anti-moth and anti-cracking properties for bamboo. In summary, this invention can greatly increase the service life of the bamboo ladder and better guarantee the climbing safety of construction workers in communication, electricity and daily construction.

[0004] The present invention is realized through the following technical solutions: (1) Cut and process the bamboo raw material of the bamboo ladder to the required length, and polish the bamboo joints smoothly. (2) Steam the cut bamboo at a high temperature for 30 minutes to kill insects, prevent corrosion and prevent moths. (3) Place the steamed bamboo in a ventilated place and air-dry it to remove the moisture inside the bamboo for later use. (4) Use resin glue as an adhesive to evenly wind the woven aramid fiber mesh cloth on the surface of the air-dried bamboo for 2-3 layers. After sufficient drying, it can become a composite material for making a bamboo ladder. (5) For the bamboo ladder made by the composite material process, at each joint of the ladder, use resin glue and aramid fiber cloth to bind and bond again to increase the strength of the bamboo ladder and prevent the bamboo ladder from loosening and cracking.

Claims

1. A method for increasing the strength of a bamboo ladder and preventing cracking, characterized in that The method comprises the following steps: (1) Raw material processing: the raw material bamboo of the bamboo ladder is cut to the required length, and the bamboo joints are polished to be smooth. (2) Insecticide and moth-proofing treatment: the cut bamboo is steamed at high temperature for 30 minutes to kill insects, prevent corrosion and prevent moth. (3) Drying treatment: the steamed bamboo is placed in a ventilated place with a spacing of 5 cm to dry in the shade for later use. (4) Material synthesis: resin glue is used as an adhesive, and the woven aramid fiber mesh cloth is evenly wrapped around the surface of the shade-dried bamboo for 2-3 layers. After being fully dried, it can become a composite material for bamboo ladders. (5) Production method: the composite material is made into bamboo ladders by drilling holes as required, and the mortise and tenon joints of each ladder are again wrapped, tied and bonded with resin glue and aramid fiber cloth to increase the strength of the bamboo ladder and prevent the bamboo ladder from loosening and cracking.

2. According to claim 1, the bamboo made by the new composite material process is characterized in that: The material of the bamboo ladder is high-temperature steaming to kill insects and prevent rot. After the bamboo is dried in the shade, it is wrapped with a mesh cloth woven with aramid fiber and sprayed with resin glue as an adhesive to increase the strength of the bamboo and prevent cracking.

3. According to claim 2, the bamboo ladder is made of specially treated bamboo, and each riveted part of the ladder is bonded with aramid fiber mesh cloth wrapped with resin glue to prevent the riveted part from loosening and increase its strength.
