Fireproof I-shaped high-strength bamboo laminated wood beam and preparation method thereof

Abstract

The invention discloses a fireproof I-shaped high-strength bamboo laminated wood beam and a preparation method thereof. The fireproof I-shaped high-strength bamboo laminated wood beam structurally comprises a high-strength bamboo laminated wood upper flange, a high-strength bamboo laminated wood lower flange, a high-strength bamboo laminated wood web and low-density laminated wood anti-shear bamboo screw bamboo pins, wherein the high-strength bamboo laminated wood upper flange is connected with the upper portion of the high-strength bamboo laminated wood web through a clamping groove A and the anti-shear bamboo screw bamboo pin A, the high-strength bamboo laminated wood lower flange is connected with the lower portion of the high-strength bamboo laminated wood web through a clamping groove B and the anti-shear bamboo screw bamboo pin B, and the beam is coated with a solvent-free environment-friendly fireproof coating. The fireproof I-shaped high-strength bamboo laminated wood beam and the preparation method thereof have the advantages that the natural bamboo resource is utilized, energy consumption is low, and pollution is small; the beam is suitable for fabricated structures and also can meet the requirement for building diversity; as the clamping grooves and the bamboo screw bamboo pins are adopted for connection, and the bamboo pins are provided with threads, connecting strength and reliability can be improved, and quality is easy to control; due to the I-shaped section, the bearing capacity and deformability of the beam are improved, materials are saved, the weight of the member is reduced, and convenience is brought to building fabrication production; the beam is coated with the solvent-free environment-friendly fireproof coating, so that the fire resistance of the beam is improved.

Description

technical field [0001] The invention relates to a fireproof I-shaped high-strength bamboo laminated beam applicable to construction engineering structures and bridge structures and a preparation method thereof, belonging to the field of engineering technology. Background technique [0002] Environmental and resource issues are imminent. Seeking suitable biomass renewable structural materials is a new direction in the field of contemporary civil engineering. my country is the world's leading bamboo-producing country and is known as the "Kingdom of Bamboo". Bamboo's short cycle, high strength, and high yield give people the idea of ​​"substituting bamboo for wood". The characteristics of raw bamboo, such as thin wall and large taper, and the increasing market demand and requirements for bamboo materials have promoted the development of industrial bamboo. [0003] At present, industrial bamboo is mainly used in decoration, decorative materials, daily necessities and other fiel...

AI Technical Summary

Problems solved by technology

However, bamboo-based composite materials are flammable materials, and their applications are restricted by fire regulations.

[0005] However, at this stage, the theory of bamboo and wood structure design in my country is not perfect, and the design methods are backward. Under the guidance of sustainable development, under the situation of increasingly scarce labor force, it is very meaningful to develop bamboo structure buildings with prefabricated and factory standardized production. Therefore, according to the modern Structural analysis technology and structural design principles are very necessary for the analysis and design of prefabricated bamboo structures

[0006] At present, the prefabricated structure with concrete and steel as the main raw materials has the following disadvantages: (1) heavy weight; (2) inconvenient transportation; (3) the size of the components is determined according to the design requirements, which is not universal, which is not conducive to Standardized production; (4) high energy consumption, high pollution, and relatively high cost; the present invention can effectively improve the above conditions
