Embodiment Construction

[0015] The specific implementation manner of the invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The combined "V"-shaped concrete-filled steel pipe column is located above the reinforced concrete floor structure at an elevation of 26.2m outside the H-axis of the east and west areas of the main stadium of the Nanjing Olympic Sports Center. The length of the inclined column is from 14m to 20m, the vertical column is about 15m high, the outer diameter of the steel tube concrete column is 1000mm, and the wall thickness of the steel tube is 18mm. The top of the CFST column intersects with the 44.28m high reinforced concrete ring beam. The angle between the inclined fork steel pipe and the vertical steel pipe ranges from 20° to 32°. Technical scheme of the present invention is created in the actual construction of this project exactly. Aiming at the problems of making and installing embedded parts, anchoring steel ...

Abstract

The invention discloses composite type V shape steel core concrete column construction method. Its features are that using embedded parts precision processing and installing for the steel tube and floor to ensure V steel tube welded connection; adopting computer setting out transversal for each phase to ensure V shape steel tube exact installation; inserting the chute into anchor connected reinforcing cage; using high position throwing down for the concrete cast to ensure steel tube concrete three-way under stress performance reach the design demand. The invention can be used in various composite type V shape steel core concrete column construction and application.

Description

technical field [0001] The invention belongs to the technical field of steel pipe concrete construction, in particular to the field of construction methods of combined "V" shaped steel pipe concrete columns. Background technique [0002] The combined "V"-shaped concrete-filled steel pipe column is welded and connected by two steel pipes at a certain angle at the bottom. After the combined "V"-shaped steel pipe is installed and welded, concrete is poured inside the steel pipe, and the top of the steel-filled steel pipe concrete-filled column intersects with the inclined beam. Due to the many and complicated curved lines connected by steel pipes, many difficulties have been brought to the manufacture and installation of embedded parts and steel pipes. The elevation of the installation location of the steel pipe is relatively high, and the distance from the edge of the platform is relatively far, so the selection of hoisting scheme is also a difficult problem. The design and p...
