Connecting joint of double-wall hollow pier column and bent cap and construction method

Abstract

The invention discloses a connecting joint of a double-wall hollow pier column and a bent cap. The double-wall hollow pier column and the bent cap are fixedly connected through a first conversion section and a bent cap conversion section or are fixedly connected through the first conversion section, a second conversion section and the bent cap conversion section; when the first conversion section and the second conversion section are fixedly connected with the bent cap conversion section, the bottom of the steel pipe in the first conversion section is connected with the top of the steel pipe of the double-wall hollow pier column through a first steel partition plate, and the top is connected with the steel rib in the second conversion section through a second steel partition plate. The top of the steel rib in the second conversion section extends into the bent cap conversion section and is connected with the steel rib in the bent cap conversion section; when the first conversion section is connected with the bent cap conversion section, the bottom of the steel pipe in the first conversion section is connected with the top of the steel pipe of the double-wall hollow pier column through the first steel partition plate, and the top of the steel pipe extends into the bent cap conversion section to be fixedly connected with the steel rib in the bent cap conversion section. The connecting joint has the advantages of wide application range, reliable connection, gentle rigidity change of the node area, good anti-seismic property and the like.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a connection node between a double-walled hollow pier column and a cover beam, and also relates to a construction method for the connection node between a hollow pier column and a cover beam. Background technique [0002] The composite pipe-concrete-steel double-walled hollow member is a new type of composite member proposed by Professor Teng Jinguang, which consists of an outer composite pipe, an inner hollow steel pipe and sandwich concrete between them. In the composite pipe-concrete-steel double-wall hollow member, the outer composite pipe has excellent corrosion resistance and can protect the inner steel pipe in a corrosive environment; at the same time, the fiber winding direction of the composite pipe is hoop or close to Circumferential, which provides lateral restraint for sandwich concrete and provides shear capacity. The existence of the inner steel pipe re...
