Prefabricated hollow bamboo floor slab and preparation method thereof

Abstract

The invention discloses a prefabricated hollow bamboo floor slab and a manufacturing method. The prefabricated hollow bamboo floor slab comprises high-strength industrial bamboo surface plates, industrial low-density bamboo plate ribs and anti-shearing bamboo pins, wherein high-strength industrial bamboo surface plates are adopted as both the upper and lower surface plates of the floor slab; the industrial low-density bamboo plate ribs are placed in equal distance between the upper and lower surface plates so as to form holes parallel to the stress direction of the floor slab; the bamboo pins are adopted to provide sufficient anti-pull and anti-shearing bearing capacity and are used for connecting the upper and lower surface plates with the plate ribs so as to form the floor slab with sufficient bearing capacity. The prefabricated hollow bamboo floor slab has the advantages of light self-weight, high bearing capacity efficiency, convenience in assembling and mounting, convenience in standardized production, simple process, relatively low manufacturing cost and the like, and the defects that a conventional assembled component is heavy, poor in universality, high in manufacturing cost and the like are greatly avoided; moreover bamboo is relatively low in carbon and environment-friendly as compared with the material of the conventional assembled component, so that a great deal of energy can be saved. The smoothness, the flatness and the hardness of the surface plate of the high-strength floor slab meet all requirements of an indoor floor slab, and no decoration is needed after mounting is completed.

Description

technical field [0001] The invention relates to a prefabricated hollow bamboo floor slab and a preparation method, which can be applied to a high-strength industrialized bamboo floor of an assembled structure, and belongs to the field of engineering technology. Background technique [0002] With the development of building industrialization, modern bamboo structure gradually shows its advantages as a new structural system. Due to the use of natural bamboo as raw materials, modern bamboo structures are more low-carbon and environmentally friendly than concrete structures and steel structure systems. Relevant surveys show that the energy consumption of bamboo production is only 1 / 8 of that of concrete and 1 / 50 of that of steel. In addition, my country's forest resources are short, and bamboo resources are relatively abundant. Natural bamboo is widely distributed and has a short growth cycle. The annual growth is 5 to 6 times that of trees. [0003] However, at this stage, th...

Problems solved by technology

[0003] However, at this stage, the design theory of prefabricated bamboo structures in my country is not perfect, and the design methods are backward. It is very necessary to analyze and design prefabricated bamboo structures based on modern structural analysis technology and structural design principles.

[0004] The disadvantages of the prefabricated structure with concrete and steel as the main raw materials are as follows: 1) heavy weight; 2) inconvenient transportation; 3) component size is determined according to design requirements, which is not universal and not conducive to standardized production; 4 ) cost is relatively high; the present invention can effectively improve this situation
