BRB inclined and X-shaped arranged dry-type connection fabricated reinforced concrete frame structure

Abstract

The invention provides a BRB inclined and X-shaped arranged dry-type connection fabricated reinforced concrete frame structure. The structure is formed by combining a prefabricated beam-column combined component (1), a prefabricated beam (2), an embedded part connecting plate (3), an anti-buckling support end part (4), an anti-buckling support BRB (5), a column-column connecting joint (6) and a beam-column combined component connecting joint (7). The BRB inclined and X-shaped arranged dry-type connection fabricated reinforced concrete frame structure is characterized in that the prefabricatedbeam-column combined component (1) and the prefabricated beam (2) are connected through the dry-type connecting joint (6), and the prefabricated beam-column combined component (1) and the beam-columncombined component (1) are connected through the dry-type connecting joint (7), so that the fabricated reinforced concrete frame structure is formed; and on the basis, the anti-buckling support (5) isarranged and combined with the fabricated reinforced concrete frame structure into a whole through the embedded part connecting plate (3) and the anti-buckling support end part (4). According to theBRB inclined and X-shaped arranged dry-type connection fabricated reinforced concrete frame structure, the defect that a dry-type connecting joint in an existing fabricated damping structure is proneto being damaged under a strong earthquake is overcome, and the bearing capacity of the damping component BRB and the energy dissipation capacity in the earthquake are fully exerted; and meanwhile, the damping component BRB can be replaced after the earthquake and has the function recoverability, so that the provided structure has the advantages of being easy to assemble, replaceable, good in anti-seismic property and the like, and further development of the fabricated concrete structure can be promoted.

Description

Technical field[0001]The invention relates to a dry connection assembled reinforced concrete frame structure with BRB diagonal and X-shaped arrangement, which is applied to an assembled building structure and belongs to the field of civil engineering.Background technique[0002]Prefabricated buildings have the advantages of high production efficiency, high construction quality, and low environmental impact, and have received extensive attention and applications. my country is located at the intersection of the world's two major seismic belts, namely the Circum-Pacific seismic belt and the Eurasian seismic belt. There are frequent seismic activities and serious earthquake disasters. Prefabricated concrete frame structures are widely used in Chinese cities. Once the building structure collapses due to earthquakes, it will cause huge economic and personal casualties, and bring immeasurable negative effects to society. For this reason, it is particularly important to improve the seismic p...

Problems solved by technology

[0005] The purpose of the present invention is to provide a dry-connected assembled reinforced concrete frame structure with BRB oblique and X-shaped arrangement, which can solve the defect that the dry-connected joints in the existing assembled damping structure are easy to be damaged under strong earthquakes, and give full play to the damping effect. The bearing capacity of the shock-absorbing component BRB and the energy dissipation capacity in the earthquake, at the same time, the shock-absorbing component BRB can be replaced after the earthquake, which has the function of recoverability, so the proposed structure has the advantages of easy assembly, replaceability, good seismic performance, etc. Advantages, can promote the further development of prefabricated concrete structures
