Production method of steel-section-concrete +-shaped section column

Abstract

The invention relates to a production method of a steel-section-concrete +-shaped section column. The produced +-shaped section column comprises a steel-concrete composite core zone and four column limbs. The production method comprises the following steps: producing T-shaped steel sections and square steel tubes; punching holes in flanges and web plates of the T-shaped steel sections and in tube walls of four sides of the square steel tubes at intervals; vertically mounting the T-shaped steel section in each column limb respectively, wherein the flange of each T-shaped steel section is positioned at an outward position of the corresponding column limb; vertically mounting the square steel tube steel sections in the core zone, wherein all the steel sections are anchored at the top of a foundation, and welding end plates to strengthen anchoring; arranging steel bars; arranging transverse stirrups; mounting a moulding plate; pouring concrete. By the production method of the steel-section-concrete +-shaped section column, provided by the invention, a specially-shaped column structure can be popularized and applied to high-rise buildings and buildings in a region with high seismic fortification intensity.

Description

technical field [0001] The invention belongs to the technical field of steel concrete structures and relates to a method for manufacturing a steel concrete + shaped section column. Background technique [0002] The frame column protrudes from the corners of the wall so that the thickness of the column limbs is equal to that of the infill wall, and the column with the limb height and thickness ratio of each limb of the section is not greater than 4, which is called a special-shaped column, including L-shaped, T-shaped, cross-shaped and Z-shaped, etc. . The frame structure and frame-shear wall structure using special-shaped columns are called special-shaped column structure systems. Compared with the traditional structural system, the column limbs of the special-shaped column structure system are as thick as the filling wall of the room, and there is no protruding column edge in the room, which can avoid the inconvenience caused by room decoration and furniture arrangement.

Problems solved by technology

However, if the solid-web section steel is arranged in the +-shaped section special-shaped column, the stirrups parallel to the length direction of the two vertical column limbs and the longitudinally stressed reinforcement of the beam in the core area of ​​the beam-column joint will be blocked by the solid-web section steel in the column. Drilling through or welding the section steel, the construction is complicated and difficult
