Special shape column

Abstract

The invention relates to a special shape column. The shape of the cross section of the special shape column is a '-' shape, a T shape, a U shape, an L shape, a crossed shape, a square shape, an oval shape or a circular shape. The invention is characterized in that the special shape column comprises reinforced concrete and steel ribs, wherein the steel ribs are positioned in the reinforced concrete, and the reinforced concrete is in a structure with combined self compact concrete and reinforced steel bars. Thereby, the structure of the special shape column can effectively reduce the unnecessary structure protrusion in the building structure, the condition of the surface formed by the self compact concrete is good, the casting and filling compactness can be easily realized, the gripping force of the reinforced steel bars can be effectively improved, the column structure with higher intensity can be obtained, and the invention can be perfectly applied to structures with high and strong carrying force and high or ultrahigh structures, has obvious environmental benefits, economic benefits and social benefits, can particularly and effectively reinforce the indexes such as pressure resistance strength, density, chopping and pulling strength, folding strength, elastic modulus and the like, and is applicable to structures of bridges, garages, retaining walls, protective walls, ordinary buildings, high buildings or ultrahigh buildings and the like.

Description

(1) Technical field [0001] The invention relates to a concrete component, in particular to a special-shaped column. (2) Background technology [0002] Concrete column structure is widely used in various building structures and is inseparable from our daily life. [0003] The cross-sections of column structures currently used in buildings are mostly square and rectangular in regular shapes. Some of these column structures are factory prefabricated. When this prefabricated column structure is combined with other elements to form a frame structure, the structure of the frame nodes is complicated and the amount of steel used is large. At the same time, the structural section size of the column exceeds the thickness of the wall, and there is a prominent column structure at the indoor corner, which is not conducive to interior decoration and furniture layout, and affects the use function. The special-shaped columns that have appeared in recent years use the on-site vibrating method. Com...

Problems solved by technology

[0003] At present, most of the column structures used in buildings have regular shapes such as square and rectangle. Some of these column structures are prefabricated in factories. When this prefabricated column structure forms a frame structure with other components, the structure of the frame joints is complicated and the steel consumption is large. At the same time, the cross-sectional size of the column exceeds the thickness of the wall, and the column structure protrudes at the corner of the room, which is not conducive to interior decoration and furniture layout, and affects the use function

The special-shaped columns that have appeared in recent years adopt the on-site vibration method. Compared with the existing square and rectangular columns, the special-shaped columns have better moment resistance and work performance, and overcome the problems caused by the column structure protruding from the wall surface. Poor disadvantages, but the use of on-site vibration, labor-intensive, complex construction, can not be industrialized construction
