Crisscross-section concrete composite special-shaped column with ends coated with channel steel and construction method of special-shaped column

Abstract

The invention discloses a crisscross-section concrete composite special-shaped column with ends coated with channel steel and a construction method of the special-shaped column, and belongs to the field of buildings. The crisscross-section concrete composite special-shaped column with ends covered with the channel steel comprises a base and a crisscross special-shaped column vertically installed on the base. The construction method of the special-shaped column comprises the following steps: binding rebars, assembling the rebars to form a combined crisscross steel skeleton, erecting a formwork,and performing casting molding. Ends of the special-shaped column are coated with the channel steel by the steel-concrete composite special-shaped column, the construction process is relatively simple, the difficulty in rebar binding is the same as the difficulty in rebar binding of ordinary reinforced concrete special-shaped columns, the outer-coated channel steel can be produced in advance andthen assembled on site, obstruction of excess steel materials at beam-column joints is avoided, the problems of insufficient internal space and difficult rebar penetration are solved, the problem of inconvenience in construction caused by complexity of steel skeletons of steel reinforced concrete special-shaped columns is effectively solved, and construction time and cost are saved; seismic performance of ordinary reinforced concrete special-shaped columns is effectively improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a composite special-shaped column with a cross-section extremity covered with channel steel concrete and a construction method thereof. Background technique [0002] Special-shaped column refers to the column whose section is L-shaped, cross-shaped, cross-shaped, and the ratio of section height to limb thickness is less than or equal to 4. The thickness of the limbs of special-shaped columns is usually consistent with the thickness of the wall, which prevents the columns from protruding from the wall, makes the interior of the building beautiful, and also indirectly increases the usable space of the room. Therefore, special-shaped columns have an irreplaceable role in architectural functions. Superiority, it is easy to be generally welcomed by users and developers, so it is widely used in practical engineering. [0003] However, due to the irregularity of the section of t...

Problems solved by technology

[0011] The invention discloses a cross-section extremity outsourcing channel steel concrete combined special-shaped column and a construction method thereof. The steel-concrete composite structure special-shaped column is used to wrap the channel steel on the outside of the special-shaped column extremities, and the channel steel and concrete are welded by bolts. The parts are connected, and the problems such as crowded steel bars and insufficient space in the concrete will not be caused by the channel steel being embedded in the concrete; in order to achieve the above-mentioned purpose, the technical solution of the present invention is:
