L-shaped section branch end external wrapped box iron-concrete composite special-shaped column and construction method thereof

Abstract

The invention discloses an L-shaped section branch end external wrapped box iron-concrete composite special-shaped column and a construction method thereof, and belongs to the field of construction. The L-shaped section end external wrapped box iron-concrete composite special-shaped column comprises a base and an L-shaped special-shaped column vertically mounted on the base, the L-shaped special-shaped column forms two branch ends, the two branch ends are provided with groove-shaped steel correspondingly, and the exterior of the two branch ends are sleeved with the groove-shaped steel; and notches of the groove-shaped steel face toward the center of the L-shaped special-shaped column, concave backs of the groove-shaped steel are exposed outside the two branch ends of the L-shaped special-shaped column, corners of the L-shaped special-shaped column are provided with angle steel, the angle steel is arranged outside the corners of the L-shaped special-shaped column in a sleeving mode, andnotches of the angle steel face toward the turning position of the L-shaped special-shaped column. The construction method of the L-shaped section branch end external wrapped box iron-concrete composite special-shaped column includes the steps of rebar bone binding, composite L-shaped steel skeleton assembling, template erecting, and moulding by casting. According to the L-shaped section branch end external wrapped box iron-concrete composite special-shaped column and the construction method thereof, the problem that steel skeletons of profile steel concrete special-shaped columns are complexand consequently construction is inconvenience is effectively solved, and the construction time and cost are saved; and anti-seismic performance of reinforced concrete special-shaped column structures is effectively improved, and the bearing capacity of the reinforced concrete special-shaped column structures 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 L-shaped cross-section extremities 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, T-shaped, or 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. It is easy to be widely welcomed by users and developers because of its superiority, so it has been widely used in practical engineering. [0003] However, due to the irregul...

Problems solved by technology

[0009] The patent number is 201721687444.2, and the name is the prior application for concrete-filled steel tube special-shaped columns. Its main technical point is that multiple pieces of steel bars are welded on the periphery. Although it solves the advantages of insufficient seismic performance of traditional special-shaped columns to a certain extent, it also has many shortcomings. , the main reason is that the special-shaped columns of pure outsourcing steel plates are greatly restricted in the actual use and construction process. First, it is not easy to plaster when used in houses. The steel plate needs multiple steel plates to be welded and formed, and the workload is very cumbersome and complicated, which greatly increases the construction cost in practical applications; the patent number is 201611266329.8, and the patent name is the prior application of L-shaped aluminum alloy concrete special-shaped columns, and its technical points are also It is metal outsourcing. In addition to the above-mentioned shortcomings, the outer surface in this application is not in the same plane. In the actual construction process, additional plastering is required for the groove, which further increases the difficulty of the work.
