Construction method of steel-section-concrete T-shaped section column

Abstract

The invention relates to a construction method of a steel-section-concrete T-shaped section column. The construction method comprises the following steps: 1) producing T-shaped steel sections and square steel tubes; 2) punching holes in steel flange plates and web plates on two sides of the T-shaped steel sections and in tube walls of four sides of the square steel tubes; 3) mounting the vertical T-shaped steel sections in each column limb of the T-shaped column respectively, and mounting vertical square steel tubes (4) in the core zone of the T-shaped section column, wherein all the steel sections (1-4) are anchored at the top of a foundation, and welding end plates to strengthen anchoring; 4) arranging longitudinal force-bearing steel bars; 5) arranging stirrups (9, 10) at certain intervals in directions parallel to the flange and the web plate of the T-shaped section column respectively by tightly adhering to the outer surfaces of the longitudinal force-bearing steel bars; 6) mounting a moulding plate; 7) pouring concrete. By the construction method of the steel-section-concrete T-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 construction method for a steel concrete T-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 T-shaped cross-section special-shaped column, the stirrup parallel to the direction of the flange and the web 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. The upper hole is punched through or welded, and the construction is complicated and difficult
