Structure having a core bar

Abstract

The present disclosure relates to a structural member with a core bar which has good mechanical strength and quality properties compared to existing metallic structural members, significantly reduces manufacturing costs, enables easy construction of various curved building structures such as a dome-shaped building structure or an arch-shaped building structure without a truss structure or a formwork to be economically feasible and excellent in construction efficiency, and contributes to the protection of the global environment. The structural member includes: at least one elastic core bar formed in a bar shape; and an outer body or an outer cover into which the at least one core bar is inserted. The core bar is formed at least one of wood such as a bamboo strip or a composite bamboo bar, a synthetic resin material, a glass fiber composite material, and a carbon fiber composite material. The outer body or the outer cover is formed of at least one of a metallic material such as aluminum, a synthetic resin material, a glass fiber composite material, and a carbon fiber composite material.

Description

technical field [0001] Compared with the previous metal building materials, the core bar building material of the present invention has obvious advantages in terms of mechanical strength and quality characteristics, and has a significant effect on reducing manufacturing costs. Not only that, when constructing the frame of dome, arch and various curved buildings, it can be easily constructed without the trouble of building trusses or formwork. Therefore, it has superior economic benefits and constructability, and is conducive to protecting the earth's environment. Background technique [0002] Metal construction materials made of steel and aluminum are widely used in the field of machinery and equipment such as automated production equipment, starting with the construction industry. [0003] The raw materials of such metal building materials are not only expensive, but also difficult to take and place because of their heavy weight. The carbon emissions generated during the ...

Problems solved by technology

However, the overall casing is made of metal materials such as aluminum, which wastes expensive metal materials and increases the economic burden

[0008] In addition, in order to connect in the length direction (extended length), a hole is left in the center of the end face of the aluminum profile, and a tapping (Tapping) process is required every time the connection is made, so the construction is troublesome and the man-hour is prolonged
