Abstract

The invention discloses a composite steel pipe concrete column-beam-column joint and a column-column inner steel pipe flange connection system. The composite steel pipe concrete column is composed of an outer steel pipe and an inner steel pipe; The outer steel beam; the stiffening components include longitudinal PBL stiffeners, diaphragms and longitudinal stiffeners between diaphragms. The inner and outer steel pipes of the composite steel pipe concrete column are divided into two parts, which are not connected into a whole. The upper and lower ends of the inner steel pipes have outer flanges. The inner steel pipes are connected, and then the outer steel pipes are installed; the inner and outer steel pipes are prefabricated in the factory, and the inner steel pipes of the upper and lower columns are connected by flanges, the inner and outer steel pipes are also connected by bolts, and the outer pipes of the upper and lower columns are connected by welding, which greatly reduces the construction cost. It can greatly adapt to the needs of industrialization, improve the construction efficiency and shorten the construction period.

Description

technical field [0001] The invention relates to a composite steel pipe concrete column-beam-column joint and a column-column inner steel pipe flange connection system, and the invention belongs to the technical field of civil engineering super high-rise building structures and large-scale pier engineering. Background technique [0002] With the development of the economy and the advancement of urbanization, high-rise and super high-rise buildings in my country continue to develop, and the structural height is constantly being broken and refreshed. Conventional structural forms can no longer meet the requirements of structural design, and more and more composite structural forms are applied to practical projects, such as: square concrete-filled steel tube column (CFST), circular steel-filled concrete column (CFT), steel concrete column (SRC) ( Also known as steel reinforced concrete column), steel tube concrete composite column (ST-RC, also known as steel tube concrete compos...
