Description

Technical Field

[0001] This utility model relates to the field of building reinforcement technology, specifically a rectangular concrete column reinforcement structure. Background Technology

[0002] In the field of building construction, rectangular concrete columns, as the main load-bearing components of buildings, directly affect the safety and durability of the entire structure due to their stability and load-bearing capacity. However, in actual use, due to various factors such as construction quality, environmental erosion, and increased load, rectangular concrete columns may experience problems such as cracks, deformation, and reduced strength, thereby affecting their normal use and safety.

[0003] To address these issues, traditional reinforcement methods typically involve increasing cross-sectional dimensions, bonding steel plates, or adding reinforcing bars. However, these methods suffer from drawbacks such as long construction periods, high costs, and significant impacts on the building's appearance and functionality. Particularly for large load-bearing components like rectangular concrete columns, traditional reinforcement methods often fail to achieve the desired reinforcement effect and may even adversely affect the overall structure of the building. Therefore, we propose a reinforcement structure for rectangular concrete columns. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete column reinforcement structure that is easy to construct, low in cost, has minimal impact on the building's appearance, and can significantly improve the load-bearing capacity of rectangular concrete columns.

[0005] The technical solution of this utility model to solve the above problems is:

[0006] A rectangular concrete column reinforcement structure includes a rectangular concrete column and a concrete beam. The four corners of the rectangular concrete column are respectively provided with full-height angle steel. The full-height angle steels are welded together by steel connecting plates with a spacing that is dense at both ends and sparse in the middle. The upper ends of adjacent full-height angle steels are welded through openings in the concrete beam by several beam-area equivalent reinforcing bars. The lower ends of the full-height angle steels are supported and welded to a steel base plate. The steel base plates are welded together.

[0007] Furthermore, the opening is filled with a first structural adhesive; the gap between the steel connecting plate and the rectangular concrete column is filled with a second structural adhesive.

[0008] Furthermore, the equivalent reinforcement in the beam area is a plain round steel bar with a diameter of 10mm to 16mm, and the spacing between adjacent equivalent reinforcement bars in the beam area is 150mm to 200mm.

[0009] Furthermore, the steel connecting plate has a thickness of 4mm and a width of 100mm.

[0010] Furthermore, the thickness of the full-height angle steel is 6mm and the width is 80mm. Beneficial effects

[0011] 1. This utility model improves the shear resistance of rectangular concrete columns by setting full-height angle steel at the four corners of the column and welding the full-height angle steel to each other with steel connecting plates at a spacing that is dense at both ends and sparse in the middle. The upper ends of adjacent full-height angle steel are welded through openings in the concrete beam by several beam-area equivalent reinforcing bars. Compared with increasing the cross-sectional size, pasting steel plates or adding reinforcing bars, this method is convenient to construct, low in cost, and highly efficient, with little impact on the appearance of the building.

[0012] 2. This utility model can significantly improve the stiffness of beam-column joints and enhance the building reinforcement effect by setting beam-area reinforcement at the top of the column and welding it with full-height angle steel. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Examples, such as Figures 1 to 6As shown, the structure includes a rectangular concrete column 1 and a concrete beam 2. The four corners of the rectangular concrete column 1 are each provided with a full-height angle steel 5. The full-height angle steels 5 are welded together by steel connecting plates 3 with a spacing that is denser at both ends and sparser in the middle. The upper ends of adjacent full-height angle steels 5 are welded through openings 7 in the concrete beam 2 by several beam-area equivalent reinforcing bars 4. The lower ends of the full-height angle steels 5 are supported and welded to a steel base plate 6, and the steel base plates 6 are welded together. This invention not only enhances the structural strength of the rectangular concrete column 1 with the full-height angle steel 5, but also provides a solid foundation for subsequent connections. The dense-at-both-ends and sparse-in-the-middle arrangement of the steel connecting plates 3 ensures the strength of the connection and optimizes the stress distribution of the structure. The beam-area equivalent reinforcing bars 4 are welded to the full-height angle steels 5, forming a stable connection node. Through ingenious design, the structure is strengthened, and the overall performance and safety are improved.

[0022] Furthermore, the opening 7 is filled with a first structural adhesive 8, which can adhere tightly to the steel bars and concrete to form a strong connection node, while preventing the penetration of moisture and corrosive substances; the gap between the steel connecting plate 3 and the rectangular concrete column 1 is filled with a second structural adhesive 9, which can effectively seal the gap and prevent the intrusion of moisture and corrosive substances, thereby extending the service life.

[0023] Furthermore, the equivalent reinforcing bars 4 in the beam area are plain round steel bars with a diameter of 10mm to 16mm, and the spacing between adjacent equivalent reinforcing bars 4 in the beam area is 150mm to 200mm.

[0024] Furthermore, the steel connecting plate 3 has a thickness of 4mm and a width of 100mm.

[0025] Furthermore, the thickness of the full-height angle steel 5 is 6mm and the width is 80mm.
