Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the embodiments of the present invention are not limited thereto.

[0041] Such as Figure 1-Figure 3As shown, this embodiment is based on a detachable and replaceable reinforced concrete column-column connection structure based on flange connection, including an upper section of reinforced concrete column 1, a lower section of reinforced concrete column 9 and a detachable and replaceable section between the two sections of reinforced concrete columns. The reinforced concrete column, wherein the detachable and replaceable reinforced concrete column includes a reinforced concrete column 4, a flange 3, a flange 2 with an overhanging plate, a shear connector, a jack 10 and a high-strength bolt 8. The shear connectors, stirrups 7 and longitudinal bars 5 are pre-embedded in the reinforced concrete column 4 , and the shear connectors and longitudin...

Abstract

The invention discloses a detachable and replaceable reinforced concrete column-column connecting structure and method based on flange connection. The detachable and replaceable reinforced concrete column-column connecting structure comprises an upper-section reinforced concrete column, a lower-section reinforced concrete column and a detachable and replaceable reinforced concrete column arrangedbetween the two sections of concrete columns. Flange plates are arranged at the two ends of the detachable and replaceable reinforced concrete column, flange plates with externally-extending plates are arranged at the two ends of the upper-section reinforced concrete column and the lower-section reinforced concrete column, shear connectors are embedded in the upper-section reinforced concrete column, a middle-section reinforced concrete column and the lower-section reinforced concrete column, and the shear connectors are connected with the flange plates in a welded manner. The detachable and replaceable reinforced concrete column is connected between the upper-section reinforced concrete column and the lower-section reinforced concrete column through the flange plates by using high-strength bolts, and a jack is used for demounting and replacing the reinforced concrete column between the outwards-extending plates of the upper flange plate and the lower flange plate. The structure configuration is simple, machining and manufacturing are convenient, the force transmission path is definite, the reinforced concrete column can be demounted and replaced in a full-life cycle, and a foundation is laid for a full-life cycle detachable and replaceable structure system.

Description

technical field [0001] The invention relates to the field of column-column connection in a detachable and replaceable structural system in the whole life cycle, in particular to a detachable and replaceable reinforced concrete column-column connection structure and method based on flange connection. Background technique [0002] The detachable and replaceable structural system of the whole life cycle is a brand-new structural system concept, which is in line with the earthquake-resistant design concept of green buildings and sustainable development. That is, the structure can be disassembled into individual components after the normal use state or service period expires, so as to realize the recycling or reuse of components; the structure can be damaged according to the expected mode under the action of earthquakes, and the damaged removable and replaceable components can be disassembled and replaced , to realize the rapid restoration of structural functions after the earthq...
