Problems solved by technology

In view of the restrictions of these specifications, if the concrete-filled steel tube columns are made, the wall thickness must be very thick, other conditions are also more stringent, and the amount of steel used is large, resulting in high cost and poor economy of the entire structure

Abstract

The invention provides a steel pipe-batten plate combined building column and a construction technology thereof. The steel pipe-batten plate combined building column comprises a column skeleton and formworks detachably mounted outside the column skeleton, wherein the column skeleton comprises square steel pipes arranged at corners of the column skeleton and batten plates arranged between adjacent square steel pipes; the batten plates are arranged in the vertical directions of the square steel pipes according to certain intervals. The square steel pipes and the batten plates are combined to form the column skeleton, the steel pipe is arranged at each corner of the whole column skeleton, the formworks are arranged among the steel pipes, and then concrete is cast in place to form the steel-concrete combined column; the steel pipes are arranged at the corners of the column skeleton, while only batten plates are arranged at the middle positions of the column skeleton, so that when a beam is connected with an independent column, steel bars can freely extend into the column body and thus a fighting phenomenon of steel bars in the conventional reinforced concrete column is avoided; after the concrete is poured, a whole is formed, so that the rigidity in a node area is better.

Description

technical field [0001] The invention relates to the technical fields of architecture and civil engineering, and is suitable for large-scale column projects such as building frame columns with large cross-sections and viaduct bridge columns, and specifically relates to a building column combined with a steel pipe and a decorative plate and a construction process thereof. Background technique [0002] National standards and regulations such as "Technical Specifications for Concrete-filled Steel Tube Structures" and "Code for Design of Steel Structures" put forward relatively high requirements for the steel pipe part of the CFST technology. For example: the ratio B / t of the side length and wall thickness of the rectangular steel pipe section should not be greater than The slenderness ratio λ of the column shall not be greater than 80. Compared with the single steel pipe, the "Code for Design of Steel Structures" has a stricter requirement that the slenderness ratio of the stee...
