Abstract

A method for reinforcing a round-log bending member through bamboo wood includes the following steps that, firstly, the surface of a round log (1) is cleaned, the defects on the surface of the round log (1) is subjected to gum dipping through compound bamboo fragments (2), longitudinal bamboo fiber strips (3) are wound in the length direction of the round log (1), circumferential-direction bamboofiber cloth (4) are wound in the circumferential direction of the round log (1), then packaging bamboo fiber fabrics (5) are wound in the circumferential direction, an external protection material (6)is brushed, the round log (1), the compound bamboo fragments (2), the longitudinal bamboo fiber strips (3), the circumferential-direction bamboo fiber cloth (4), the packaging bamboo fiber fabrics (5) and the external protection material (6) form a whole, and bending reinforcement of the round log (1) is achieved. The invention aims to provide the method for reinforcing the round-log bending member through bamboo wood, the advantages, such as good toughness and high tensile strength, of the bamboo wood are made full use of, the reinforcement of the round-log bending member is achieved, the core goal that ancient buildings are repaired as before is reached, meanwhile abundant bamboo resources in our country are made full use of, and the method is in line with the existing sustainable development concept in our country.

Example Embodiment

[0044] Examples:
[0045] Picture 11 A schematic diagram of the overall structure of a bamboo reinforced round wood bending member in the present invention is given. The structure consists of round wood 1, composite bamboo fragments 2, longitudinal bamboo fiber strips 3, circular bamboo fiber cloth 4, and encapsulated bamboo fibers. The fabric 5 and the external protective material 6 are composed of composite bamboo fragments 2 dipped in glue to fill up the cracks and other defects of the log 1 and then ground, and then the longitudinal bamboo fiber strips 2 are continuously and evenly wound along the bending area of ​​the log 1 with an adhesive. After curing, wind a 25cm circular bamboo fiber cloth 4 on both ends of the circular log 1 to anchor the longitudinal bamboo fiber strip 3, the winding angle is 30° perpendicular to the axis of the circular log 1, and the longitudinal bamboo fiber strip 3 and the circular bamboo fiber cloth 4 are glued into a whole, then wrap the 0.2mm thick encapsulated bamboo fiber fabric 5 on the entire surface of the log 1 to make the component beautiful, and then evenly paint the surface of the encapsulated bamboo fiber fabric 5 , So that the surface of the component is smooth, beautiful, durable, and fixed and formed. The round wood 1, the composite bamboo fragments 2, the longitudinal bamboo fiber strips 3, the circular bamboo fiber cloth 4, the encapsulated bamboo fiber fabric 5 and the external protection 6 are integrated, That is, a bamboo reinforced log bending member is formed.
[0046] Compared with the traditional method of strengthening round timber bending members, the present invention has obvious advantages. It not only greatly improves the bearing capacity and durability of the structure, but also makes full use of existing renewable resources and saves resources. , Reduce energy consumption, reduce pollutant emissions, and follow my country's existing sustainable development concepts.
