Orthogonal glued bamboo material for building structure and preparation method thereof

Abstract

The invention discloses an orthogonal glued bamboo material for a building structure and a preparation method thereof. The orthogonal glued bamboo material for the building structure comprise a plurality of bamboo strips; the bamboo strips include the short bamboo strips and the long bamboo strips, and the cross sections of the short bamboo strips and the long bamboo strips are the same; the multiple short bamboo strips are arranged side by side to form longitudinal row plates; the multiple long bamboo strips are arranged side by side to form horizontal row plates; the longitudinal row platesand the transverse row plates are the same in size, the width of the longitudinal row plates is equal to the length of the long bamboo strips, the width of the transverse row plates is equal to the length of the short bamboo strips, the longitudinal row plates and the transverse row plates are overlapped in an interlaced mode to form the bamboo material, the axis of the short bamboo strips is perpendicular to the axis of the long bamboo strips, and the cross section of the bamboo material is rectangular; the bamboo strips are glued and connected; and fiber reinforced composite materials, steelfibers or high-strength fiber materials are arranged between the adjacent bamboo strips. The bamboo material is good in strength, toughness, stability and durability.

Description

technical field [0001] The invention belongs to the field of steel-bamboo structural materials, and relates to an orthogonally glued bamboo material for building structures and a preparation method thereof. Background technique [0002] my country is one of the countries with the richest bamboo resources and the longest history of bamboo cultivation in the world. At present, the bamboo forest area is nearly 6 million hectares, and the bamboo resources are abundant. With the gradual development of civil engineering in the direction of environmental protection, low carbon and green environmental protection, steel and bamboo composite structures are also continuously applied in the construction field, and have received more attention in recent years. As a low-cycle, renewable, sustainable, environmentally friendly and low-carbon resource, bamboo can replace wood as the main material of wood structures after being glued with special techniques and construction methods. Bamboo a...

Problems solved by technology

[0003] With the development of the civil engineering industry and the requirements for material performance, the existing bamboo has low mechanical properties and cannot meet the requirements for material performance. It is necessary to provide a composite bamboo with higher strength, toughness, stability and durability.
