Description

Technical Field

[0001] The utility model belongs to the technical field of structural engineering, and particularly relates to a detection and reinforcement configuration for the void between a concrete-filled square steel tube column. Background Technique

[0002] With the continuous progress and development of structural engineering, due to its superior bearing capacity and seismic performance, concrete-filled square steel tube columns have been widely used in high-rise buildings, bridges and large public facilities. However, in actual projects, the void between the square steel tube and the concrete is likely to occur due to various factors such as construction errors, material aging, and temperature changes, which will affect the bearing capacity of the entire structure.

[0003] At present, there are already some detection and reinforcement methods for the void problem of concrete-filled square steel tube columns in actual projects. Among them, a common reinforcement method is to increase the filler inside the steel tube or adopt a special connection method to enhance the connection strength between the steel tube and the concrete. However, these methods often have problems such as complex construction, high cost, and poor reinforcement effect, and it is difficult to meet the needs of actual projects.

[0004] In terms of detection, although there are some non-destructive testing techniques that can be used to detect the void of concrete-filled steel tube columns, these techniques are often affected by factors such as equipment limitations, construction disturbances, and on-site environments, and it is difficult to popularize to each construction site.

[0005] Therefore, it is necessary to propose a detection and reinforcement configuration for the void between a concrete-filled square steel tube column. Content of the Utility Model

[0006] The purpose of the utility model is to provide a detection and reinforcement configuration for the void between a concrete-filled square steel tube column, which can effectively increase the contact area between the square steel tube and the concrete, reduce the occurrence of voids, and achieve accurate detection of the void situation.

[0007] The technical solution adopted by the utility model is specifically as follows:

[0008] A detection and reinforcement configuration for the void between a concrete-filled square steel tube column includes a square steel tube. A plurality of limiting rods are arranged inside the square steel tube.

A cavity is arranged inside the limiting rod, and an opening is arranged at one end of the cavity far away from the square steel tube.

[0009] A striking component is installed inside the cavity, and the striking component is used to detect whether there is a void inside the square steel tube.

[0010] The hitting assembly includes a mounting bracket fixed on the inner wall of the limiting rod. A sliding column is assembled inside the mounting bracket. One end of the sliding column away from the opening of the limiting rod is fixed with a hitting ball. A fixed block is also fixed on the outer side of the sliding column between the mounting bracket and the hitting ball, and a spring is assembled between the fixed block and the mounting bracket;

[0011] A side wall hitting structure is also installed on the outer side of the fixed block, and the side wall hitting structure is used to detect whether the limiting rod is voided.

[0012] The side wall hitting structure includes at least one fixing plate fixed on the outer side of the fixed block.

A spring piece is also assembled inside the fixing plate, and the spring piece is connected to the sliding plate.

[0013] An arc-shaped hitting block is arranged at one end of the sliding plate away from the spring piece.

[0014] The technical effects achieved by the present utility model are as follows:

[0023] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation modes of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0024] As Figures 1-5 shown, a detection and reinforcement configuration for the void in a square concrete-filled steel tube column includes a square steel tube 1. A plurality of limiting rods 2 are arranged inside the square steel tube 1. When pouring concrete into the inside of the square steel tube 1, through the arrangement of the limiting rods 2, the contact area between the square steel tube 1 and the concrete can be increased, and thus the situation of concrete void in the square steel tube 1 can be reduced. A plurality of limiting arc strips 3 are arranged around the circumference inside the square steel tube 1 and around the limiting rods 2. Through the arrangement of the limiting arc strips 3, the limiting arc strips 3 can further increase the contact area between the square steel tube 1 and the concrete, and by using the gap between the limiting rods 2 and the limiting arc strips 3, the firmness between the concrete and the limiting rods 2 can be increased, thereby restricting the situation of concrete void. One end of the limiting rod 2 away from the square steel tube 1 extends to the outside of the square steel tube 1 and is flush with the outer wall of the square steel tube 1. A cavity 4 is arranged inside the limiting rod 2, and an opening is arranged at one end of the cavity 4 located away from the square steel tube 1.

[0025] A striking component is installed inside the cavity 4, and the striking component is used to detect whether there is a void inside the square steel tube 1.

[0026] Referring to the attached Figures 3-4 , the striking component includes a mounting frame 5 fixed on the inner wall of the limiting rod 2. A sliding column 6 is assembled inside the mounting frame 5. The sliding column 6 can slide and rotate with respect to the mounting frame 5. One end of the sliding column 6 away from the opening of the limiting rod 2 is fixed with a striking ball 9. The striking ball 9 is made of metal. Thus, when the striking ball 9 strikes the inner wall of the limiting rod 2, the sound generated is the same as when knocking on the square steel tube 1, and the materials of the square steel tube 1, the limiting rod 2, and the limiting arc strip 3 are the same. A fixing block 7 is also fixed on the outer side of the sliding column 6 and between the mounting frame 5 and the striking ball 9, and a spring 8 is assembled between the fixing block 7 and the mounting frame 5.

[0027] When using this detection tool, the sliding column 6 can be pulled, thereby driving the striking ball 9 to move, and driving the spring 8 to be compressed through the fixing block 7. Then, release the sliding column 6, so that the sliding column 6 drives the sliding column 6 and the striking ball 9 to hit the inner wall of the limiting rod 2 through the elasticity of the spring 8. Whether the concrete inside the square steel tube 1 and the limiting rod 2 is void can be detected through the impact sounds at multiple positions and multiple impact settings.

[0028] On the outer side of the fixed block 7, a sidewall hitting structure is also installed, and the sidewall hitting structure is used to detect whether the limiting rod 2 is disengaged.

[0029] Refer to the appendix Figures 4-5 , the sidewall hitting structure includes at least one fixed plate 10 fixed on the outer side of the fixed block 7. A sliding plate 11 is slidably connected inside the fixed plate 10, and a bearing plate 14 corresponding to the sliding plate 11 is provided on the inner wall of the limiting rod 2. An elastic piece 12 is also assembled inside the fixed plate 10, and the elastic piece 12 is connected to the sliding plate 11. An arc-shaped hitting block 13 is provided at one end of the sliding plate 11 away from the elastic piece 12, and the arc-shaped hitting block 13 is made of the same material as the square steel pipe 1;

[0030] When it is necessary to detect whether the concrete on the sidewall of the limiting rod 2 is void, the sliding column 6 can be rotated, thereby driving the fixed block 7 to rotate and generating a torsional force on the spring 8. When the sliding column 6 is released, the torsional force of the spring 8 wanting to reset can drive the fixed block 7 and the sliding column 6 to rotate and reset. Then, the fixed plate 10 is driven to rotate by the fixed block 7, so that the sliding plate 11 and the arc-shaped hitting block 13 on the fixed plate 10 hit the bearing plate 14. After the hitting is completed, the remaining torsional force drives the sliding plate 11 and the arc-shaped hitting block 13 to continue rotating. When rotating, to prevent the arc-shaped hitting block 13 from getting stuck with the bearing plate 14, the sliding plate 11 slides inside the fixed plate 10, and an elastic piece 12 is provided, so that the arc-shaped hitting block 13 can avoid getting stuck with the bearing plate 14;

[0031] This application can effectively increase the contact area between the square steel pipe 1 and the concrete while keeping the construction simple and the cost low, reduce the occurrence of void phenomenon, and achieve accurate detection of the void situation, improving the bearing capacity of the square steel pipe 1 concrete column.

[0032] Further, when rotating the sliding column 6, to prevent damage to the spring 8, the spring 8 and the mounting bracket 5 can also be rotatably connected through a rotating piece, and the rotating piece can be torsionally spring-connected to the mounting bracket 5.

[0033] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, if not specifically stated and limited, are implemented according to the conventional means in the art.
