FRP biomass composite component with circular exterior and square interior and manufacturing method

Abstract

The invention relates to an FRP biomass composite component with the round exterior and the square interior and a manufacturing method. The component sequentially comprises a bamboo layer, a gypsum layer, a hollow ribbed thin-wall steel cylinder, a biomass material and an FRP profile square cylinder from outside to inside. The manufacturing method comprises the steps that the hollow ribbed thin-wall steel cylinder is cast in a factory at a time, and the four steel ribs are evenly distributed in the hollow ribbed thin-wall steel cylinder; the FRP section square cylinder is placed on the inner side of the hollow ribbed thin-wall steel cylinder, and the FRP section square cylinder is fixed to the center of the steel cylinder through the four steel ribs; the space formed by the steel cylinder and the FRP section bar square cylinder is filled with biomass materials, a gypsum layer with the thickness not smaller than 20 mm is tightly wrapped outside the steel cylinder, the outer side of the gypsum layer is wrapped with a bamboo layer, and the bamboo fiber direction of the bamboo layer is transverse. Compared with a traditional construction method, the manufacturing method has the advantages of light weight, high strength, resource conservation, environment friendliness, corrosion resistance, fire resistance, attractive appearance and the like.

Description

technical field [0001] The invention relates to an outer circle and inner square FRP biomass composite component and a manufacturing method, and belongs to the field of building component manufacturing. Background technique [0002] The traditional building structure is self-heavy and the construction process is cumbersome. The use of a large number of building materials will accelerate the consumption of non-renewable resources and have an impact on the environment. New building structural components can solve the above problems through improvement. Steel has high strength, uniform material and flexible connection, but poor stability and fire resistance. [0003] FRP materials can meet the requirements of mechanical properties of building structures while saving resources and protecting the environment. In recent years, bamboo and wood structures have been gradually applied in my country. Bamboo has a short growth cycle, light weight, low strength loss at high temperature,...

Problems solved by technology

In recent years, bamboo and wood structures have been gradually applied in my country. Bamboo has short growth cycle, light weight, low strength loss under high temperature, renewable and easy processing. However, due to the low bearing capacity of bamboo and wood structure columns, low strength and anisotropy, The application of bamboo and wood structures in high-rise buildings and bridges is limited
