Problems solved by technology

However, due to the lack of forest resources in our country, the state has strict control over timber felling. Even in artificial afforestation, due to the long period of timber maturity, the source of logs is limited, and it is impossible to build a large number of timber structures.

Embodiment 1

[0026] Embodiment 1: as figure 1 and figure 2 As shown, the bamboo long plate member of the present invention comprises upper and lower two-layer bamboo strip surface layers 1 and longitudinally continuous fiber layers 3 and transverse connection layers 2 alternately arranged between the two-layer bamboo strip surface layers 1, and the longitudinal continuous The fiber layer 3 is composed of continuous bamboo materials arranged longitudinally (such as long bamboo sheets), and the transverse connection layer 2 is composed of vertical or oblique bamboo strips or hemp ropes. Stiffeners 4 can be provided in the longitudinal continuous fiber layer 3 as required. The stiffening strips 4 are arranged longitudinally or horizontally, or arranged in a grid. The arrangement direction and shape of the stiffening strips 4 can be selected according to actual needs. The materials of the stiffening strips 4 are carbon fiber reinforced plastics, glass fiber reinforced plastics, and aramid fi...

Embodiment 2

[0034] Embodiment 2: as image 3 and Figure 4 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1. First, the bamboo raft surface layer 1, the longitudinal continuous fiber layer 3 and the transverse connecting layer 2 are woven into a bamboo curtain. If the transverse connecting layer 2 is made of other materials, also weave Form a curtain, and then impregnate the bamboo curtain with adhesive. Layer and tile each layer of material on the pressurized equipment again, first tile a layer of bamboo strip surface layer 1, then alternately tile the horizontal connection layer 2 and the longitudinal continuous fiber layer 3, the material consumption ratio of the two can be adjusted, the longitudinal The higher the proportion of the continuous fiber layer 3 is, the greater the bending stiffness and bearing capacity of the bamboo beam member will be. Finally, spread one deck of bamboo strip surface layer 1 again. The binder in the material is sol...

Embodiment 3

[0043] Embodiment 3: as Figure 5 and Figure 6 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1. First, the bamboo raft surface layer 1, the longitudinal continuous fiber layer 3 and the transverse connecting layer 2 are woven into a bamboo curtain. If the transverse connecting layer 2 is made of other materials, also weave into a curtain shape, and then in the bamboo beam member, that is, the longitudinal continuous fiber layer 3 or the transverse connection layer 2 is provided with a tubular reserved channel 6, the outer surface of the bamboo curtain and the reserved channel 6 is impregnated with adhesive, and the reserved channel 6 The material can be metal pipe, plastic pipe or composite pipe. Layer and tile each layer of material on the pressurized equipment again, first tile a layer of bamboo strip surface layer 1, then alternately tile the horizontal connection layer 2 and the longitudinal continuous fiber layer 3, the material co...

Abstract

The invention discloses a bamboo beam member, which comprises two layers of bamboo strip surface layers and longitudinal continuous fiber layers and transverse connection layers alternately arranged between the two layers of bamboo strip surface layers. Composed of bamboo, the horizontal connection layer is composed of vertical or oblique bamboo strips or hemp ropes. The invention is a bamboo beam with low cost, convenient processing and manufacture, large size, high rigidity and strength, good processability, and can meet the requirements of use function and durability as a structural component.

Description

technical field [0001] The invention mainly relates to the field of building components in civil engineering, in particular to a bamboo beam component that can be used as a structural component. Background technique [0002] In today's society, reinforced concrete structures, steel structures and various composite structures with steel and cement as the main raw materials are the most important structural forms in the field of civil engineering. Metallurgy and cement industries have always been high energy consumption and high pollution industries. The production of steel and cement needs to consume a lot of energy and non-renewable natural resources, and at the same time produce a lot of waste water, waste gas and waste residue, which seriously affects the ecological environment and does not conform to sustainable development. requirements. The use of natural, environmentally friendly, and renewable organic materials is processed and made into structural components through...
