Flexible connection structure for building block infilled wall and concrete frame structure, and construction method thereof

Abstract

The invention discloses a flexible connection structure for a building block infilled wall and a concrete frame structure, and a construction method thereof, belongs to the field of seismic resistancefor structure engineering, and aims at solving the problem of an insufficient planar outer bearing force of an infilled wall of a flexible connection structure between the infilled wall and a concrete frame. The flexible connection structure for the building block infilled wall and the concrete frame structure comprises a back plate, two side wing plates and a plurality of anchoring steel bars. The flexible connection structure is arranged between the building block infilled wall and the concrete frame, the plurality of anchoring steel bars are arranged on the plate surface of one side of theback plate, the anchoring steel bars are poured into the concrete frame, one side wing plate is arranged on the plate edges at the left side and the right side of the plate surface of the other sideof the back plate separately to form a groove, and building blocks of the building block infilled wall are located in the grooves. According to the flexible connection structure for the building blockinfilled wall and the concrete frame structure, connection between the concrete frame and the building block infilled wall is enhanced, so that the building block infilled wall is not liable to be separated from the concrete frame under a seismic action, the planar outer bearing force of the building block infilled wall is remarkably increased, and the stability of the building block infilled wall is ensured.

Description

technical field [0001] The invention belongs to the anti-seismic field of structural engineering, and in particular relates to a flexible connection construction structure of a block filling wall and a concrete frame structure and a masonry construction method of the block filling wall. Background technique [0002] Filled wall concrete frame structure is a widely used form of building structure. At present, the connection methods between the infill wall and the concrete frame are generally divided into two types: rigid connection and flexible connection. Among them, the rigid connection scheme is simple in construction and is the most common in actual engineering. However, due to the tight connection between the infill wall and the frame in the rigid connection scheme, the stiffness and strength of the structure will change, which will easily lead to brittle failure of the structure, such as shear failure at the end of the column, short column effect, etc., which will have...
