A prefabricated l-shaped special-shaped steel pipe concrete composite column

Abstract

The invention discloses a prefabricated L-shaped special steel pipe concrete combined column. The prefabricated L-shaped special steel pipe concrete combined column comprises a first concrete combined column and a second concrete combined column, wherein each of the first concrete combined column and the second concrete combined column comprises a first side plate, a second side plate, first square iron, second square iron and a reinforcement plate; the two side surfaces of the reinforcement plate are respectively connected with the inner side surface of the first side plate and that of the second side plate; the two ends of the first side plate are respectively connected with the right side surface of the first square iron and the left side surface of the second square iron; the two ends of the second side plate are respectively connected with the right side surface of the first square iron and the left side surface of the second square iron; the first side plate is flush with the front surface of the first square iron and that of the second square iron; the second side plate is flush with the back of the first square iron and that of the second square iron. The prefabricated L-shaped special steel pipe concrete combined column is good in bearing capacity, ductility and observability, saves space, and is short in construction time.

Description

technical field [0001] The invention relates to a concrete composite column, in particular to a prefabricated L-shaped special-shaped steel tube concrete composite column. Background technique [0002] At present, my country's "Technical Regulations for Rectangular Steel Tube Concrete Structures" (GECS159: 2004) provides that the steel tube concrete columns are mainly composed of inner diaphragm type, outer ring plate type and other joints, but so far, the existing L-shaped concrete columns are often used. Local buckling occurs, bearing capacity and ductility are poor, and indoor columns often protrude from corners, which effectively reduces the usable area and visibility of the house. In addition, most of the existing L-shaped concrete columns are poured on the construction site. The construction is inconvenient, and the construction time is long, which seriously affects the construction period. Contents of the invention [0003] The purpose of the present invention is to ...
