Description

Technical Field

[0001] The utility model belongs to the technical field of cavity column connection, and particularly relates to a cavity column connection structure. Background Art

[0002] A cavity column is a commonly used structural element in architecture and civil engineering, and it has a design with a central cavity. This design aims to reduce the structural weight, improve the material utilization rate, and in some cases, it can also provide additional functionality, such as for pipeline layout or improving the thermal efficiency of the building. When installing the cavity column, a connection structure is required to connect with the base steel bars to ensure the safety and stability of the structure.

[0003] Traditional connection methods for cavity columns include welding connection and sleeve connection. Among them, in the welding connection, the reserved bars at both ends are welded during use, and then the connection of the cavity column is completed. However, during use, it is difficult to effectively control the welding stub depth of the reserved bars during the welding process, and it is difficult to weld or fill the reserved bars in the central part, resulting in poor welding effect, unable to achieve effective connection of the cavity column, and prone to causing the cavity column to tilt; although the sleeve connection can realize the connection of two opposite reserved steel bars by rotating the threaded sleeve, although the threaded connection of the outer sleeve can achieve quick alignment, if no limiting measures are taken, it is easy to produce sliding during use, resulting in loosening of the connection, affecting the stability of the structure, and also affecting the safety of the entire building.

[0004] Therefore, the utility model proposes a new cavity column connection structure to solve the problems existing in the above-mentioned prior art. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a cavity column connection structure, which has the advantages of being convenient to limit the connection structure and enhance the stability after the cavity column is connected, and solves the problems existing in the existing cavity column connection technology that the existing connection structure can achieve quick alignment through the threaded connection of the outer sleeve, but if no limiting measures are taken, it is easy to produce sliding during use, resulting in loosening of the connection, affecting the stability of the structure, and also affecting the safety of the entire building.

[0007] (2) Technical Solutions

[0008] To achieve the above-mentioned purpose of the cavity column connection technology, the utility model provides the following technical solutions:

[0009] A cavity column connection structure.

[0010] As a preferred embodiment of the cavity column connection structure of the present utility model: The cavity column connection structure includes a first outer sleeve, which is arranged on the first steel bar on the upper side of the base and is threadedly connected to the first steel bar; a limiting component, which is arranged between the first steel bar and the second steel bar at the lower end of the cavity column and is adapted to the second steel bar and the first outer sleeve; a guiding component, which is arranged on the second steel bar above the limiting component and is adapted to the limiting component and the second steel bar.

[0011] Based on the above technical features: The cooperation of the first outer sleeve and the limiting component can be used to achieve the rapid connection of the base and the cavity column. The connection between the first outer sleeve and the second steel bar is limited and fixed by the limiting component, thereby increasing the stability after the connection of the first steel bar and the second steel bar and avoiding the sliding of the connection or the connection components. At the same time, when the first steel bar and the second steel bar are connected, the guiding component facilitates the connection of the first steel bar and the second steel bar, ensures the precise alignment during the connection process, and simplifies the installation process. It solves the problem of poor stability of the existing connection structure.

[0012] As a preferred embodiment of the cavity column connection structure of the present utility model: The limiting component includes a second outer sleeve threadedly connected to the surface of the second steel bar, and the second outer sleeve is threadedly connected to the connection groove at one end of the first outer sleeve.

[0013] Based on the above technical features: Through the connection between the second outer sleeve and the connection groove, the rapid connection of the base and the cavity column can be achieved.

[0015] Based on the above technical features: When the second outer sleeve is threadedly connected to the connection groove of the first outer sleeve, the guiding block is synchronously abutted against the inner wall of the second outer sleeve. When connecting, the guiding block is pushed to synchronously compress the spring. Thus, after the first outer sleeve and the second outer sleeve are threadedly connected, the guiding block generates an outward force through the tension of the spring, so that the guiding block tightly abuts against the inner wall of the second outer sleeve, effectively preventing the threaded connection part from loosening due to vibration or load, ensuring the stability and reliability of the connection, and enhancing the durability of the overall structure. At the same time, one side of the guiding block extends into the second outer sleeve and abuts against the inner wall of the second outer sleeve. The guiding block is arranged in a semi-circular spherical structure. The semi-circular spherical structure of the guiding block enables it to more smoothly adapt to and contact the inner wall of the second outer sleeve, facilitating the connection with the second outer sleeve.

[0021] Based on the above technical features: after the second outer sleeve moves downward to be connected to the first outer sleeve, the limiting cap can perform a threaded movement on the surface of the second steel bar by rotation, so that one side of the limiting cap abuts against the second outer sleeve. Through the fastening action of the limiting cap, the loosening of the connection part under external force or vibration is effectively prevented, and the safety and reliability of the whole structure are improved.

[0022] As a preferred solution of a cavity column connection structure described in the present utility model: the guiding assembly includes a movable ring slidably arranged on the surface of the second steel bar, at least one limiting rod is arranged at the bottom of the movable ring, one end of each limiting rod penetrates through the limiting cap and extends to one end of the second outer sleeve, and is adapted to a limiting hole arranged at the end of the second outer sleeve close to the limiting rod;

[0023] Based on the above technical features: after the limiting cap abuts against the second outer sleeve, the movable ring can be moved to slide downward on the surface of the second steel bar, and the two limiting rods penetrate through the limiting cap and are slidably connected to the limiting holes at one end of the second outer sleeve, enhancing the anti-shear ability during connection and ensuring stability.

[0028] 1. Through the settings of the first outer sleeve, the limiting component and the guiding component, this connecting structure can utilize the cooperation of the first outer sleeve and the limiting component to achieve the rapid connection of the base and the cavity column. The connection between the first outer sleeve and the second steel bar is limited and fixed by the limiting component, thereby increasing the stability after the connection of the first steel bar and the second steel bar and avoiding sliding of the connection or the connecting components. At the same time, when the first steel bar and the second steel bar are connected, the guiding component facilitates the connection of the first steel bar and the second steel bar, ensuring precise alignment during the connection process and simplifying the installation process; it solves the problem of poor stability of the existing connecting structure.

[0029] 2. Through the setting of the limiting component, when connecting adjacent first steel bars and second steel bars, the connection between the first outer sleeve and the second steel bar can be limited and fixed by the limiting component, thereby increasing the stability after the connection of the first steel bar and the second steel bar and avoiding sliding of the connection or the connecting components.

Specific implementation manner

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0039] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0040] A connection structure for a hollow column, used to connect the base 1 and the hollow column 2, including a first outer sleeve 3, a limit component 4 and a guide component 5; among them

[0041] The first outer sleeve 3 is arranged on the first steel bar 11 on the upper side of the base 1 and is threadedly connected to the first steel bar 11;

[0042] The limit component 4 is arranged between the first steel bar 11 and the second steel bar 21 arranged at the lower end of the hollow column 2 and is used in cooperation with the second steel bar 21 and the first outer sleeve 3;

[0043] The guide component 5 is arranged on the second steel bar 21 on the upper side of the limit component 4 and is used in cooperation with the limit component 4 and the second steel bar 21;

[0044] In this embodiment, when connecting adjacent first steel bars 11 and second steel bars 21, the connection between the first outer sleeve 3 and the second steel bar 21 can be limited and fixed by the limiting component 4, thereby increasing the stability after the connection of the first steel bar 11 and the second steel bar 21 and preventing the connection or the connecting components from sliding. At the same time, when the first steel bar 11 and the second steel bar 21 are connected, the guiding component 5 can also facilitate the connection of the first steel bar 11 and the second steel bar 21, ensure the precise alignment during the connection process, and simplify the installation process.

[0045] As a preferred implementation, as Figure 2 、 Figure 3 and Figure 4 shown, the limiting component 4 includes a second outer sleeve 41 threadedly installed on the surface of the second steel bar 21. A plurality of the first steel bars 11 are aligned with a plurality of the second steel bars 21. A connection groove 44 is formed on one side of the first outer sleeve 3. One end of the second outer sleeve 41 is threadedly connected to the connection groove 44. An inner sleeve 43 is arranged inside the connection groove 44. A support rod 45 is slidably installed on one side of the inner sleeve 43. One end of the support rod 45 is fixedly installed with a guiding block 46. A spring 47 is sleeved outside the support rod 45. Two ends of the spring 47 are fixedly connected to the surface of the guiding block 46 and the inner sleeve 43 respectively.

[0046] In this embodiment, when the second outer sleeve 41 is threadedly connected to the connection groove 44 of the first outer sleeve 3, the guiding block 46 is simultaneously pressed against the inner wall of the second outer sleeve 41. When connecting, the guiding block 46 is pushed to simultaneously compress the spring 47. Thus, after the first outer sleeve 3 and the second outer sleeve 41 are threadedly connected, the guiding block 46 generates an outward force through the tension of the spring 47, so that the guiding block 46 closely abuts against the inner wall of the second outer sleeve 41, effectively preventing the threaded connection part from loosening due to vibration or load, ensuring the stability and reliability of the connection, and enhancing the durability of the overall structure. At the same time, one side of the guiding block 46 extends into the second outer sleeve 41 and abuts against the inner wall of the second outer sleeve 41. The guiding block 46 is set as a semi-circular spherical structure. The semi-circular spherical structure of the guiding block 46 enables it to more smoothly adapt to and contact the inner wall of the second outer sleeve 41, facilitating the connection with the second outer sleeve 41.

[0047] As a preferred implementation, as Figure 3 、 Figure 4 and Figure 5 shown, a limiting cap 42 is slidably connected to the surface of the second steel bar 21. The limiting cap 42 is located above the second outer sleeve 41, and one side of the limiting cap 42 is in contact with one end of the second outer sleeve 41.

[0048] In this embodiment, after the second outer sleeve 41 moves downward and is connected to the first outer sleeve 3, the limit cap 42 can perform a threaded movement on the surface of the second steel bar 21 by rotation, so that one side of the limit cap 42 abuts against the second outer sleeve 41. Through the fastening action of the limit cap 42, loosening of the connection part when subjected to external forces or vibrations is effectively prevented, improving the safety and reliability of the entire structure.

[0049] As a preferred embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the guiding assembly 5 includes a movable ring 52 slidably mounted on the surface of the second steel bar 21. Two limit rods 53 are fixedly installed at the bottom of the movable ring 52. One end of each of the two limit rods 53 penetrates through the limit cap 42 and extends to one end of the second outer sleeve 41. A plurality of limit holes 54 are formed in one end of the second outer sleeve 41 close to the limit rods 53, and both limit rods 53 are slidably connected to adjacent limit holes 54;

[0050] In this embodiment, after the limit cap 42 abuts against the second outer sleeve 41, the movable ring 52 can be moved to slide the movable ring 52 downward on the surface of the second steel bar 21, so that the two limit rods 53 penetrate through the limit cap 42 and are slidably connected to the limit holes 54 at one end of the second outer sleeve 41, enhancing the anti-shear ability during connection and ensuring stability;

[0051] As a preferred embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the bottom end of the limit rod 53 is set to a semi-circular shape, and the edge of one end of the limit hole 54 is set to a rounded corner;

[0052] In this embodiment, through the semi-circular shape at the bottom end of the limit rod 53 and the rounded corner edge of the limit hole 54, it is helpful for the limit rod 53 to be inserted into or withdrawn from the limit hole 54 more smoothly, reducing friction and wear during the installation process.

[0053] As a preferred embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, a guiding groove 51 is formed in the inner wall of one end of the second outer sleeve 41. The guiding groove 51 is located on one side of the guiding block 46, and the guiding groove 51 is set to a trumpet shape;

[0054] In this embodiment, the horn-shaped setting helps the guiding block 46 enter the second outer sleeve 41 more smoothly. The horn-shaped guiding groove 51 can effectively guide and align the guiding block 46, and can automatically adjust even when the guiding block 46 is slightly offset, ensuring that the guiding block 46 enters smoothly, thereby improving the fault tolerance rate and installation efficiency of the connection process.

[0055] During the construction of the cavity column connection structure of the present utility model: when the second outer sleeve 41 is threadedly connected to the connection groove 44 of the first outer sleeve 3, the guiding block 46 is simultaneously pressed against the inner wall of the second outer sleeve 41. When connecting, the guiding block 46 is pushed to simultaneously compress the spring 47. Thus, after the first outer sleeve 3 and the second outer sleeve 41 are threadedly connected, the guiding block 46 generates an outward force through the tension of the spring 47, making the guiding block 46 tightly abut against the inner wall of the second outer sleeve 41, effectively preventing the threaded connection part from loosening due to vibration or load, ensuring the stability and reliability of the connection, and enhancing the durability of the overall structure. After the second outer sleeve 41 moves downward to be connected to the first outer sleeve 3, the limit cap 42 can be rotated to perform a threaded movement on the surface of the second steel bar 21, so that one side of the limit cap 42 abuts against the second outer sleeve 41. Through the fastening action of the limit cap 42, the loosening of the connection part when subjected to external force or vibration is effectively prevented, improving the safety and reliability of the entire structure. After the limit cap 42 abuts against the second outer sleeve 41, the movable ring 52 can be moved to make the movable ring 52 slide downward on the surface of the second steel bar 21, and the two limit rods 53 are passed through the limit cap 42 and slidably connected to the limit holes 54 at one end of the second outer sleeve 41, enhancing the anti-shear ability during connection to ensure stability. Through the semicircle at the bottom end of the limit rod 53 and the rounded edge of the limit hole 54, it helps the limit rod 53 to insert or withdraw from the limit hole 54 more smoothly, reducing friction and wear during the installation process, helping the guiding block 46 enter the second outer sleeve 41 more smoothly. The horn-shaped guiding groove 51 can effectively guide and align the guiding block 46, and can automatically adjust even when the guiding block 46 is slightly offset, ensuring that the guiding block 46 enters smoothly, thereby improving the fault tolerance rate and installation efficiency of the connection process.
