Frame formed from solid-web steel pipe concrete combination columns and combination beam, and construction method thereof

Abstract

The present invention relates to a frame formed from solid-web steel pipe concrete combination columns and a combination beam, and a construction method thereof. The frame is formed by connecting combination columns and a combination beam through a node, wherein the combination beam is horizontally arranged between the combination columns, the node is an outer sleeve integral node filled with self-compacting concrete, the combination column is a segmental solid-web steel pipe concrete combination column, the combination beam is an I-shaped honeycomb concrete beam with an external pre-stress upper flange being rectangular steel pipe, the node is fixedly connected to the combination column through an upper connection ring and a lower connection ring, the node is connected to the combination beam through an end beam connection plate and a node web plate connection plate, and the self-compacting fine-aggregate concrete of the combination beam and the self-compacting fine-aggregate concrete in the upper wing edge steel pipe of the node end beam are communicated to each other. According to the present invention, with the frame and the construction method, the complex problem of the connection node between the solid-web steel pipe concrete combination column and the I-shaped beam having the upper flange being the rectangular steel pipe is solved.

Description

technical field [0001] The invention relates to a building frame structure in the field of civil and architectural structures, in particular to a frame composed of solid composite steel pipe concrete composite columns and composite beams and a construction method thereof. Background technique [0002] In the conventional reinforced concrete frame structure system, the frame joints are mostly reinforced concrete cast-in-place joints. This kind of reinforced concrete joints needs formwork, binding steel bars and then pouring concrete like frame beams and columns. Not only the bearing capacity of the components is low, but the construction period is long. Moreover, the nodes are prone to damage under the action of earthquakes. With the rapid development of the civil construction industry, concrete-filled steel tube structures have been widely used in long-span, heavy-load and super-high buildings. The concrete-filled steel tube frame with prestressed tendons is a new structural...
