Bamboo-wound pipe and cast concrete integrated column for buildings and preparation method of bamboo-wound pipe and cast concrete integrated column for buildings

Abstract

The invention discloses a bamboo-wound pipe and cast concrete integrated column for buildings and a preparation method of the bamboo-wound pipe and cast concrete integrated column for the buildings. The column comprises a protection layer, a bamboo-wound decoration structure, a middle bamboo-wood combined winding structure and an inner concrete structure sequentially from outside to inside. The bamboo-wound decoration structure is formed by uniformly and continuously winding bamboo fibrous belts and lining mesh belts through resin glue in an annular and longitudinal plane winding combined manner. The middle bamboo-wood combined winding structure is formed by winding transverse bamboo split units or transverse wood veneers and longitudinal fibrous materials in an annular and longitudinal winding combined manner, wherein the winding angle is 25-86 degrees. Due to the fact that the inner concrete is under protection and binding functions of a bamboo-wound pipe, natural erosion and buckling failure are avoided, and long service life, low cost, remarkable energy saving and emission reduction effects and considerable economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a bamboo winding pipe concrete pouring composite column for building and a preparation method thereof. Background technique [0002] Reinforced concrete columns are the most basic load-bearing components in various engineering structures such as houses, bridges, and hydraulic engineering. The current manufacturing processes are mainly: cast-in-place columns and prefabricated columns. Cast-in-place reinforced concrete columns have good integrity, but the formwork requires a lot of work; prefabricated reinforced concrete columns are more convenient to construct, but the quality of joint connections is poor. In addition, the bearing column is not only subjected to pressure load but also shear force in the actual application process, especially the slender column is prone to instability and failure in the direction of 45 degrees. [0003] Bamboo winding composite pipe is a new typ...
