[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] Example:

[0027] The utility model provides a technical solution: a concrete floor expansion joint column pin reinforcement part,

[0028] It comprises a first connecting member 1 with a groove on the inner side, wherein the first connecting member 1 is provided in two groups and is used to support the expansion joint gap of the concrete floor;

[0029] A steel bar structure 22, wherein the steel bar structure 22 is installed on the first connecting member 1 in a plurality of groups and is equidistantly arranged. The steel bar structure 22 is used to connect concrete;

[0030] A telescopic mechanism, which is arranged between the two groups of the first connecting members 1, with both ends of the telescopic mechanism respectively connected to the steel structure 22, and is used for adaptive adjustment of the steel structure 22 to changes in the expansion joint gap of the concrete floor;

[0031] An adjustment mechanism is provided on the top of the two groups of the first connecting members 1 and connects the two groups of the first connecting members 1. The adjustment mechanism is used to adjust the spacing between the two groups of the first connecting members 1 according to the spacing of the expansion joints of the concrete floor.

[0032] In specific implementation:

[0033] First Connector 1: This is the base of the reinforcement, with grooves on its inside to support the gap in the concrete floor expansion joint. This design allows the first connector to be firmly embedded in the expansion joint, providing support for subsequent structures.

[0034] Rebar structures 22: These are mounted on the first connector 1 and are arranged in several equidistant groups. Their primary function is to connect the concrete and provide additional strength and stability to resist deformation of the expansion joint caused by factors such as temperature changes and foundation settlement.

[0035] Telescopic Mechanism: Located between the two sets of first connectors 1, its ends are connected to the steel structure 22. This mechanism's design allows it to adaptively adjust to changes in the concrete floor's expansion joint. When the joint expands or contracts due to temperature fluctuations or other factors, the mechanism adjusts accordingly within a small range to maintain structural integrity and functionality.

[0036] Adjustment Mechanism: Located on top of and connecting the two sets of first connectors (1), the adjustment mechanism adjusts the spacing between the two sets of first connectors based on the actual spacing of the concrete floor expansion joint. This adjustability ensures that the reinforcement can accommodate expansion joints of varying widths, providing a flexible solution.

[0037] Specifically, the first connecting member 1 further includes a reinforcing plate 11 connected to the outer side of its lower end, which serves to enhance the support stability at the bottom.

[0038] Specifically, one end of the steel bar structure 22 is provided with an arc, which serves to expand the connection area and to adjust the telescopic adjustment in a small range. One end of the steel bar structure 22 passes through the inner side of the first connecting member 1, and is connected to the steel bar structure 22 of another group of first connecting members 1 on the inner side and the connection is completed through a telescopic mechanism. The telescopic mechanism can adaptively adjust the spacing in a small range according to the changes in the expansion joint gap of the concrete floor. The first connecting member 1 is also equidistantly provided with several groups of connection holes 15 for installing the steel bar structure 22, so that the steel bar structure 22 can move outward and inward on the first connecting member 1 to adapt to different usage requirements of the expansion joint gap of the concrete floor.

[0039] Specifically, the telescopic mechanism includes two groups of special-shaped metal parts 23 and elastic parts 24. The elastic parts 24 are connected between the two groups of special-shaped metal parts 23. The two groups of special-shaped metal parts 23 are respectively connected between the two groups of steel bar structures 22. The special-shaped metal parts 23 can be steel bars or other metal parts with high corrosion resistance. The special shape can be an arc shape to provide space for movement and change to meet the changes in the gap after installation in the expansion joint of the concrete floor. The elastic part 24 is a workpiece with elastic force and can be a spring. It tensions and stretches the special-shaped metal parts 23, and together plays a fixing role that changes with the changes in the gap of the expansion joint of the concrete floor.

[0040] Specifically, several groups of slide grooves 12 for installing the adjustment mechanism are equidistantly provided on the top of the first connecting member 1. The adjustment mechanism includes a slider 13 whose lower end is embedded in the slide groove 12 and a fixed workpiece 14. The fixed workpiece 14 is screwed into the two groups of sliders 13 on the first connecting member 1. The slide groove 12 and the slider 13 can be T-shaped or other shapes that will not fall off. The fixed workpiece 14 can be a screw plus a nut or other workpiece that can play a fixing role, and has the function of being fixed according to the position after the slider 13 moves.

[0041] Specifically, the length of the slide groove 12 is greater than that of the slider 13, providing sliding space for the slider 13 to adapt to the change in the spacing between the two groups of first connecting members 1, so as to meet the changing usage requirements of the gap behind the expansion joint of different concrete floors.

[0042] Working Principle: The first connector 1 serves as the foundation of the reinforcement. The inner sides of the two sets of first connectors 1 are provided with grooves for support and deformation space. A reinforcing plate 11 attached to the outer side of the lower end enhances the support stability of the base. Several sets of steel reinforcement structures 22 are equidistantly mounted on the first connector 1, each with a curved end extending through the inner side of the first connector 1 and secured by connection holes 15, providing additional strength and stability. Elastic members 24 are connected between the special-shaped metal members 23, which are in turn connected between the steel reinforcement structures 22, allowing for adaptive adjustment according to changes in the expansion joint gap. The length of the chute 12 is greater than that of the slider 13, providing sliding space for the slider to accommodate changes in the spacing between the two sets of first connectors 1. When the concrete floor expansion joint expands and contracts, the expansion mechanism achieves a small range of adaptive adjustment through the cooperation of the special-shaped metal members 23 and the elastic member 24. The adjustment mechanism allows the distance between the two sets of first connectors 1 to be adjusted as needed by moving the slider 13 within the chute 12, thereby adapting to different expansion joint gaps and ensuring the stability and durability of the floor.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
