Problems solved by technology

In order to ensure that the two different components of steel and concrete can work together, certain measures must be taken (such as welding studs or taking a certain thickness of the protective layer), otherwise the combined effect will not be achieved

Embodiment Construction

[0013] The L-shaped steel concrete special-shaped column with channel steel hollow frame, the web in the frame can bear the transverse shear force between the steel and concrete and at the same time play the role of a stud, which is very beneficial to ensure the cooperative work of the steel and concrete. Moreover, the webs can transmit shear force between the columns, which can effectively prevent the shear lag phenomenon of the special-shaped column section. Due to the repetitive nature of the earthquake, the configuration of cross webs can effectively improve the seismic performance and shear capacity. The cross webs are welded on both sides of the channel steel, and form a whole space with the channel steel, which not only has good overall rigidity to bear the load during the construction stage, but at the same time, the closed space formed by the web bars and the channel steel exerts certain constraints on the internal concrete It is very beneficial to improve the bearing...

Abstract

The invention discloses a L-shaped steel reinforced concrete special-shaped column matching with fasting skeleton of channel steel, comprising L-shaped reinforced concrete special-shaped columns and fasting skeleton of channel steel. The fasting skeleton of channel steel is matched with said L-shaped reinforced concrete special-shaped columns and said fasting skeletons of channel steel are connected by cross battened column. The L-shaped steel reinforced concrete special-shaped columns matching with fasting skeleton of channel steel can ensure section steel and concrete work in phase by reasonably matching section steel so as to improve the bearing ability and anti-shock performance of common RC special-shaped column. It makes special-shaped column structure apply widely in high-rise building and the building in the region with high earthquake intensity , especially the high-rise building in the region against more than eight degree of anti-shock.

Description

technical field [0001] The invention relates to a combined structure of steel and concrete and a mixed structure, in particular to a steel-concrete special-shaped column structure. Background technique [0002] The special-shaped column structure is a new type of structure developed in recent years. It is composed of L, T, and ten-shaped columns. The width of the columns is as thick as the filling wall, avoiding the protrusion of the columns, and can organically combine the beauty of the building with the flexibility of use, provide users with a comfortable working and living environment, and increase the number of rooms. The actual usable area is very high, and the "household rate" is high, which is very popular. In order to promote this new structure, the state has promulgated a number of guiding documents. However, with the deepening of engineering application and research, some limitations of the currently used reinforced concrete (RC) special-shaped columns are clearl...
