Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel - wrapped reinforcement structure for top - floor columns. Background Art

[0002] After rigorous design and calculation, by wrapping steel materials outside the concrete column, that is, the steel - wrapped column structure, the bearing capacity and seismic performance of the concrete column are improved. This structure is widely used in building construction. However, at the intersection position of the top of the column and the bottom of the beam in the steel - wrapped column structure, the externally - wrapped steel materials cannot directly pass through the beam to the roof, resulting in difficult construction at the intersection position of the top of the steel - wrapped column and the bottom of the beam, and relatively low strength at the intersection position of the top of the steel - wrapped column and the bottom of the beam, which affects the bearing capacity and seismic performance of the steel - wrapped column. Therefore, it is necessary to provide a steel - wrapped reinforcement structure for top - floor columns to solve the problem of relatively low strength at the intersection position of the top of the steel - wrapped column and the bottom of the beam in the prior art. Summary of the Invention

[0003] The purpose of the utility model is to provide a steel - wrapped reinforcement structure for top - floor columns, which can solve the problem of relatively low strength at the intersection position of the top of the steel - wrapped column and the bottom of the beam in the prior art.

[0004] The utility model is implemented as follows:

[0005] A steel - wrapped reinforcement structure for top - floor columns includes a steel - wrapped column main body, a first reinforcement beam, and a second reinforcement beam; the longitudinal angle steels at the corners of the steel - wrapped column main body extend upward into the floor slab and are fixedly connected to the floor slab, the first reinforcement beam is arranged around the top surface of the steel - wrapped column main body and is fixedly connected to the bottom surface of the beam body; the second reinforcement beam is arranged around the side wall of the steel - wrapped column main body and is fixedly connected to the bottom surface of the floor slab; the first reinforcement beam and the second reinforcement beam are respectively fixedly connected to the longitudinal angle steels of the steel - wrapped column main body.

[0006] The first reinforcement beam includes several first unit beams, and the first unit beams are horizontally connected between two adjacent longitudinal angle steels, and several first unit beams are circumferentially arranged at the top edge of the steel - wrapped column main body.

[0007] The cross - section of the first unit beam is L - shaped, so that the horizontal section of the first unit beam is fixedly connected to the bottom surface of the beam body through several first implanting connectors, the vertical section of the first unit beam is in fit connection with the top edge of the steel - wrapped column main body, and the horizontal section and the vertical section at the end of the first unit beam are connected by three - sided fillet welding to the longitudinal angle steel.

[0008] The second reinforcement beam includes several second unit beams, and the second unit beams are horizontally connected between two adjacent longitudinal angle steels, and several second unit beams are circumferentially arranged on the top side wall of the steel - wrapped column main body and are in fit connection with the bottom surface of the floor slab.

[0009] The cross-section of the second unit beam is L-shaped, so that the horizontal section of the second unit beam is attached to the bottom surface of the floor slab and fixedly connected through the first implanted connector. The vertical section of the second unit beam is attached to the top side wall of the steel-encased column main body, and the horizontal and vertical sections at the end of the second unit beam are welded and fixed to the longitudinal angle steel.

[0010] The top section of the longitudinal angle steel extending into the floor slab is fixed on the floor slabs on both sides of the beam body through the second implanted connector.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Since the utility model is provided with the first reinforcement beam and the second reinforcement beam, the first reinforcement beam is used to fixedly connect the bottom surface of the beam body and the longitudinal angle steel, and connect and fix the bottom of the beam body to the top of the steel-encased column main body. The second reinforcement beam is used to fixedly connect the bottom surface of the floor slab and the longitudinal angle steel, and connect and fix the bottom of the floor slab to the top of the steel-encased column main body. At the same time, circumferential reinforcement is formed at the top of the steel-encased column main body, thus ensuring the structural strength at the intersection position between the steel-encased column main body and the bottom of the beam body, and further ensuring the bearing capacity and seismic performance of the steel-encased column main body, and the construction method is simple and convenient.

[0013] 2. Since the upper end of the longitudinal angle steel at the corner of the steel-encased column main body of the utility model extends into the floor slabs on both sides of the beam body and is fixed, the column top structural strength of the steel-encased column main body is further improved, which is easy to construct, and solves the problem that the strength of the intersection position between the top of the steel-encased column main body and the bottom of the beam is low due to the fact that the steel-encased column main body cannot pass through the beam body to the roof in the prior art.
