Steel-bamboo combination pipe and manufacturing method thereof

Abstract

The invention discloses a steel-bamboo combination pipe. The interior of an inner steel pipe is hollow, the inner surface of the inner steel pipe is coated with an inner protective layer, the outer surface of the inner steel pipe is glued with one or more layers of bamboo strips through resin adhesive, cross-sectional areas of the one or more layers of bamboo strips are not less than 1.5 times ofa cross-sectional area of the inner steel pipe, the length direction of the bamboo strips is consistent with the height direction of the inner steel pipe, every two adjacent layers of bamboo strips are glued and spliced with each other to be combined into a predetermined cross-sectional shape, the outside of the outermost layer of bamboo strips is continuously wrapped with one or more layers of bamboo slicing slices to constitute a protective barrier and an outer restraint, and the bamboo fiber direction of the bamboo slicing slices is perpendicular to an axis of the inner steel pipe. The steel-bamboo combination pipe is easy and convenient to manufacture, good in integrity, high in bearing capacity, good in durability, and high in architectural aesthetics, the composite bamboo strips glued on the periphery have the function of auxiliary bearing, the wound bamboo slicing slices have the strong restraint function, thus buckling of the steel pipe is restrained, and according to the steel-bamboo combination pipe, a new product is provided for construction of ecological buildings.

Description

technical field [0001] The invention relates to a composite pipe structure, in particular to a steel-bamboo composite pipe and a manufacturing method thereof, belonging to the field of civil engineering. Background technique [0002] Steel pipe is a form of steel structure with light weight and high strength. As a structural component, steel pipe can be used as beam and column members in the field of structural engineering. It has the advantages of high bearing capacity and good ductility, but steel pipe also has certain limitations. For example, under the condition of plane bending, the bending rigidity of the steel pipe is small, local buckling damage is prone to occur, and the surface of the steel pipe is prone to corrosion. The simple steel pipe structure has high steel consumption, high cost, and poor economy. [0003] Concrete is filled in the steel pipe and compacted to increase the strength and rigidity of the steel pipe to form a steel pipe concrete structure, which...

AI Technical Summary

Problems solved by technology

However, under the action of load, the steel pipe still has defects such as local buckling and surface corrosion. At the same time, there are shortcomings such as self-heavy weight and large material consumption.

[0004] In summary, whether it is a simple steel pipe structure or a steel pipe concrete structure, under load, its steel pipes are prone to local buckling, which reduces the use efficiency of steel pipe materials; at the same time, the surface of steel pipes is facing the test of environmental corrosion and shortened service life
