Semi-assembled bamboo plywood-steel pipe dust collection mountain flour concrete combined column and manufacturing method thereof

Abstract

The invention relates to a semi-assembled bamboo plywood-steel pipe dust collection mountain flour concrete combined column, further relates to a manufacturing method of the semi-assembled bamboo plywood-steel pipe dust collection mountain flour concrete combined column and belongs to the technical field of engineering structure bearing columns. The semi-assembled bamboo plywood-steel pipe dust collection mountain flour concrete combined column comprises a bamboo plywood layer, a steel pipe, a dust collection mountain flour concrete column, steel pull rods and nuts. The dust collection mountain flour concrete column is located in the steel pipe, the bamboo plywood layer is bonded on the outer wall of the steel pipe, and dust collection mountain flour concrete is prepared from cement adulterated with dust collection mountain flour. The steel pull rods are arranged perpendicular to the axial direction of the steel pipe in a crossed mode, the two ends of the steel pulling rods are providedwith the nuts, and the nuts are connected with the steel pulling rods through threads. According to the combined column, a steel pipe-dust collection mountain flour concrete reinforcement strategy isadopted, the slender proportion of the combined column can be reduced, anti-compression instable failure of the large-slender proportion combined column is regulated, the anti-compression strength isimproved to reduce anti-compression deformation and creeping, the anti-compression bearing capacity of the combined column is improved, and traditional decoration technological treatment such as embedding, wrapping, riveting, grinding and coating can be adopted on the surface.

Description

technical field [0001] The invention relates to the technical field of load-bearing columns of engineering structures, in particular to a semi-assembled bamboo plywood-steel tube dust-collecting stone powder concrete composite column and a manufacturing method thereof. Background technique [0002] my country's bamboo resources are very rich, and the development and utilization of bamboo is the priority theme of the national medium and long-term scientific and technological development plan. At present, bamboo plywood is the most widely used bamboo product in industrial production and application, but the application of bamboo plywood in the field of structural engineering is mainly as templates for concrete structures, interior decoration materials, etc., and the application area is narrow and the method is single. There are few applications, and it is still in the low-end development stage. It is urgent to develop new utilization methods of bamboo plywood. [0003] In the...

Problems solved by technology

The stone dust in the air is the main pollution source of PM2.5. It is difficult to use after recycling. It needs to be landfilled to prevent secondary environmental pollution, which consumes a lot of manpower, material resources and land resources.
