Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a longitudinal steel bar anti-deviation structure for a large-section core column. Background Art

[0002] The existing method of preventing the longitudinal reinforcement of the frame core column from deviating mainly adopts positioning hoops. If a frame core column with a large cross-sectional size is encountered, during the pouring of concrete, with the impact of concrete and the interference of the vibrating rod, the longitudinal reinforcement is very likely to be deviated if only relying on the constraint of the positioning hoops. Once the longitudinal reinforcement is deviated, the cross-sectional size of the column after forming cannot be guaranteed and chiseling and repairing will also waste a lot of manpower and material resources. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a large-section core column longitudinal reinforcement anti-displacement structure, which can prevent the longitudinal reinforcement of the frame core column with a larger cross-sectional size from being displaced during the pouring of concrete.

[0005] Furthermore, the two annular steel bars and two fastening steel plates around the longitudinal reinforcement of each frame core column are in a tic-tac-toe shape.

[0006] Furthermore, the through groove is a strip-shaped groove.

[0007] Furthermore, the fastener is a hexagonal bolt.

[0008] Furthermore, the large-section core column longitudinal reinforcement anti-deviation structure also includes a gasket, and the gasket is located between the fastener and the annular steel bar.

[0009] Furthermore, the fastening steel plate is located in the annular steel bar and is in contact with the annular steel bar.

[0010] Furthermore, the plurality of annular steel bars are parallel to each other.

[0011] Furthermore, the plurality of fastening steel plates are parallel to each other.

[0012] Furthermore, each of the annular steel bars is perpendicular to each of the fastening steel plates.

[0013] Furthermore, some of the annular steel bars have different lengths, some of the fastening steel plates have different lengths, and two short annular steel bars and four short fastening steel plates form a casting space.

[0014] Compared with the prior art, the large-section core column longitudinal reinforcement anti-displacement structure of the present invention also includes a plurality of annular steel bars, a plurality of fastening steel plates and a plurality of fasteners. Each annular steel bar is provided with a through groove. Each frame core column longitudinal reinforcement is clamped between two annular steel bars. The fastening steel plates are located on both sides of the frame core column longitudinal reinforcement and pass through the annular steel bars.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be another intermediate component through which it is fixed. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be another intermediate component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be another intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] See also Figures 1 to 4 The present invention discloses a large-section core column longitudinal reinforcement anti-deviation structure, which includes a plurality of frame core column longitudinal reinforcements 10, a plurality of annular steel bars 20, a plurality of fastening steel plates 30, a plurality of fasteners 40 and a gasket 50.

[0024] Each annular steel bar 20 is provided with a through slot 21, and the through slot 21 is a strip-shaped slot. The fastener 40 is a hexagonal bolt.

[0025] Each frame core column longitudinal steel bar 10 is clamped between two annular steel bars 20. The fastening steel plates 30 are located on both sides of the frame core column longitudinal steel bars 10 and pass through the annular steel bars 20. The fasteners 40 fix the annular steel bars 20 and the fastening steel plates 30 through the grooves 21. The gasket 50 is located between the fasteners 40 and the annular steel bars 20. Each frame core column longitudinal steel bar 10 is clamped between the two annular steel bars 20 and the two fastening steel plates 30 to prevent the frame core column longitudinal steel bar 10 from being offset during pouring. The two annular steel bars 20 and the two fastening steel plates 30 around each frame core column longitudinal steel bar 10 are in a well shape. At this time, a plurality of annular steel bars 20 are parallel to each other. A plurality of fastening steel plates 30 are parallel to each other. Each annular steel bar 20 is perpendicular to each fastening steel plate 30. The lengths of a plurality of annular steel bars 20 are different, the lengths of a plurality of fastening steel plates 30 are different, and two short annular steel bars 20 and four short fastening steel plates 30 form a pouring space 60.

[0026] Through the above design, the large-section core column longitudinal steel bar anti-deviation structure has greater rigidity than the traditional positioning stirrup anti-deviation device. Under the impact of concrete and the interference of the vibration plate, the frame core column longitudinal steel bar 10 is not easy to deviate, thereby improving the one-time casting rate of the large-section core column, ensuring the cross-sectional size, and avoiding later chiseling and repair.

[0027] The large-section core column longitudinal reinforcement anti-misalignment structure is made entirely of steel, which can not only effectively prevent the frame core column longitudinal reinforcement 10 from misalignment, but is also easy to install and not easy to fall off during construction, thus completely realizing turnover. It is widely used in modern high-rise and super-high-rise buildings, has high work efficiency, and is very practical.

[0028] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
