Description

Technical Field

[0001] The present application relates to a steel-concrete corner column structure, and in particular to a steel-frame concrete corner column structure for a building, belonging to the technical field of construction engineering. Background Art

[0002] Steel-concrete structures offer advantages such as a short construction period and excellent seismic resistance. However, compared to traditional cast-in-place concrete beam-column structures, the connection points between steel corner columns and crossbeams, for example, require higher structural strength, which cannot be met by conventional welding methods. Existing corner column structures mostly connect only the upper and lower steel columns or the left and right crossbeams, without providing a complete connection and fixation between the upper and lower steel columns and the left and right crossbeams. Furthermore, these connection points present difficulties in formwork support during the pouring of the concrete cladding, and the subsequent installation of the glass curtain wall lacks steel supports that are securely connected to the main load-bearing structure, making installation more difficult.

[0003] Therefore, there has long been a lack of a reliable corner column structure that can not only anchor the upper steel columns and the lower steel columns, but also anchor the left steel beams and the right steel beams, thereby solving the technical problem of low strength of the connection nodes between the existing steel corner columns and the beams. At the same time, it is also beneficial to the fixation of the casting formwork and the subsequent installation of the glass curtain wall. Summary of the Invention

[0004] The purpose of the present application is to address the defects and shortcomings of the existing corner column structures, most of which only connect the upper and lower steel columns or the left and right cross beams, without integrally connecting and fixing the upper and lower steel columns and the left and right cross beams. At the same time, the connection node parts of the corner column structure are difficult to support the formwork when pouring the concrete covering layer and are difficult to install the glass curtain wall later. The present application provides a building steel frame concrete corner column structure with a reasonable structure that can not only anchor the upper and lower steel columns, but also anchor the left and right steel cross beams, and is also conducive to the fixation of the pouring formwork and the later installation of the glass curtain wall.

[0005] In order to achieve the purpose of the above application, the technical solution of the present application is: a building steel frame concrete corner column structure, including an upper steel column and a lower steel column, characterized in that: the upper steel column and the lower steel column are located on the same straight line and the lower end of the upper steel column is welded and fixed to the upper end of the lower steel column, a first steel beam is fixed on one side of the welding joint between the upper steel column and the lower steel column, and a second steel beam is fixed on the other side of the welding joint between the upper steel column and the lower steel column, and the upper steel column, the lower steel column, the first steel beam and the second steel beam are fixed. A connecting steel seat is installed at the connection node, and the connecting steel seat includes an upper connecting steel plate, a lower connecting steel plate and an intermediate connecting plate. The upper connecting steel plate is respectively connected and fixed to the upper steel column, the first steel beam and the second steel beam, and the lower connecting steel plate is respectively connected and fixed to the lower steel column, the first steel beam and the second steel beam. The upper connecting steel plate and the lower connecting steel plate are connected by one or more intermediate connecting plates. The outer sides of the upper steel column, the lower steel column, the first steel beam and the second steel beam are respectively fixed with multiple outer embedded parts and cast with a concrete covering layer.

[0006] Furthermore, the upper connecting steel plate and the lower connecting steel plate have the same shape and size and are parallel to each other. The upper end face of the first steel beam and the upper end face of the second steel beam are fixed to the lower surface of the upper connecting steel plate, and the lower end face of the first steel beam and the lower end face of the second steel beam are fixed to the upper surface of the lower connecting steel plate.

[0007] Furthermore, a notch is provided at the same corner of the upper connecting steel plate and the lower connecting steel plate, the notch of the upper connecting steel plate is fixed to the upper steel column, and the notch of the lower steel column is fixed to the lower steel column.

[0008] Furthermore, the outer sides of the upper steel column, the lower steel column, the first steel beam and the second steel beam are installed with casting templates, and the outer sides of the upper steel column, the lower steel column, the first steel beam and the second steel beam are cast with a concrete covering layer through the casting template.

[0009] Furthermore, a glass curtain wall is provided on the outer side of the concrete covering layer, and the outer end of the outer embedded part supports and fixes the glass curtain wall through a curtain wall support member.

[0010] The beneficial effects of this application are:

[0011] 1. This application involves fixing connecting steel seats at the connection points between the upper and lower steel columns and the steel beams on both sides.

The external embedded parts can be used to fix and limit the casting template during the construction phase. During the installation phase, they can be used as fixing bases for installing and fixing the glass curtain wall, thereby facilitating the fixing of the casting template and the subsequent installation of the glass curtain wall.

The outer embedded parts can be used to fix and limit the casting template during the construction phase, and can be used as a fixing seat for installing and fixing the glass curtain wall during the installation phase.

[0026] The upper steel column 1 and the lower steel column 2 are located on the same straight line, the lower end of the upper steel column 1 is welded and fixed with the upper end of the lower steel column 2, and the upper steel column 1 and the lower steel column 2 can adopt common I-shaped steel or square steel. One side of the welding joint of the upper steel column 1 and the lower steel column 2 is welded and fixed with the first steel cross beam 3 arranged horizontally, and the other side of the welding joint of the upper steel column 1 and the lower steel column 2 is welded and fixed with the second steel cross beam 4 arranged horizontally.

[0027] The connection node part of the upper steel column 1, the lower steel column 2, the first steel cross beam 3 and the second steel cross beam 4 is provided with a connecting steel seat 5.
