Description

Technical Field

[0001] This utility model relates to the field of steel component connection technology, and in particular to a connection device for heterogeneous steel column nodes in a conversion layer. Background Technology

[0002] Transformed layer anisotropic steel members are high-performance structural materials manufactured using special metallurgical processes. Their mechanical properties are directionally controlled by constructing a gradient transformation layer within the steel matrix. This technology utilizes multi-layer composite rolling and controllable heat treatment processes to create a continuously varying microstructure and mechanical property distribution across the member's cross-section, from the surface to the core. The surface typically acquires a high-hardness martensitic structure to improve wear resistance and fatigue strength, while the core maintains a tough ferrite-pearlite structure to ensure overall impact resistance. The various components are typically connected by welds, bolts, or rivets.

[0003] In existing technologies, steel structure support column connecting components are typically installed using multiple bolts. This method requires installing each bolt individually, increasing on-site construction costs and workload. Furthermore, when component replacement is needed, the disassembly process is cumbersome and inconvenient, affecting subsequent maintenance efficiency. After long-term use, bolts may corrode or lose preload, adding unnecessary workload to later maintenance.

[0004] Therefore, it is necessary to provide a connection device for the heterogeneous steel column nodes in the conversion layer to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a connection device for the node of the heterogeneous steel column in the conversion layer, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a conversion layer anisotropic steel column node connection device, comprising a first steel column and a second steel column, one end of the first steel column being fixed with a mounting base, the second steel column being inserted into the mounting base, the mounting base having an inner cavity, the inner cavity being provided with a connecting component, the connecting component being provided in multiple sets and arranged in a ring, and the mounting base being provided with a pressure regulating component communicating with the inner cavity.

[0007] As a further embodiment of this utility model, the connecting assembly includes a liquid cylinder a fixed in the inner cavity, and multiple liquid cylinders a are provided and arranged in a ring. A rod is inserted inside the liquid cylinder a, and a piston plate a is fixed on one end of the rod and fits tightly against the inner wall of the liquid cylinder a. A groove is provided on the side of the second steel column to fit the end of the rod.

[0008] As a further embodiment of this utility model, the ends of the plurality of insertion rods are provided with arc-shaped ends.

[0009] As a further embodiment of this utility model, a spring is provided inside the liquid cylinder a, and the two ends of the spring are fixed to the side of the piston plate a and the side of the inner cavity, respectively.

[0010] As a further embodiment of this utility model, the pressure regulating assembly includes a liquid cylinder b fixed to the outer wall of the mounting base and communicating with the inner cavity. A nut sleeve is fixed inside the end of the liquid cylinder b away from the mounting base. A threaded rod inserted into the liquid cylinder b is connected to the internal thread of the nut sleeve. An end plate that fits tightly against the inner wall of the liquid cylinder b is fixed to one end of the threaded rod.

[0011] As a further embodiment of this utility model, an end plate is fixed to one end of the threaded rod located outside the liquid cylinder b, and a handle rod is fixed to the side of the end plate.

[0012] As a further embodiment of this utility model, a rubber sleeve is fitted onto the surface of the handle rod, and the length of the rubber sleeve is equal to the length of the handle rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] A pressure regulating component injects a certain amount of liquid into the inner cavity, creating hydraulic pressure. This hydraulic pressure drives multiple connecting components to work synchronously, uniformly clamping the second steel column inserted into the mounting base at multiple points around its circumference. This securely connects the first and second steel columns into a single unit, effectively improving the connection stability. When removal is needed, rotating the pressure regulating component releases the hydraulic pressure within the inner cavity and connecting components, releasing the clamping force on the second steel column and allowing for quick removal. This eliminates the need for manual installation and removal of multiple bolts, significantly improving the efficiency of assembling and disassembling the first and second steel columns.

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5 This utility model provides a connection device for a non-uniform steel column node in a conversion layer, including a first steel column 4 and a second steel column 5. One end of the first steel column 4 is fixed to a mounting base 3. The second steel column 5 is inserted into the mounting base 3. An inner cavity 6 is formed inside the mounting base 3, and a connecting assembly 1 is provided inside the inner cavity 6. Multiple sets of the connecting assembly 1 are arranged in a ring. A pressure regulating assembly 2 communicating with the inner cavity 6 is provided on the mounting base 3. When connecting the first steel column 4 and the second steel column 5, the second steel column 5 is inserted into the mounting base 3. By rotating the input end of the pressure regulating assembly 2, a certain amount of liquid is forced into the inner cavity 6 through the pressure regulating assembly 2. This generates hydraulic pressure inside the inner cavity 6, which in turn drives multiple sets of connecting components 1 to work synchronously. These components clamp the second steel column 5, which is inserted into the mounting base 3, at multiple points around its circumference, thus firmly connecting the first steel column 4 and the second steel column 5 into one unit. This effectively improves the connection stability of the first steel column 4 and the second steel column 5. When it is necessary to remove them, the hydraulic pressure inside the inner cavity 6 and the connecting components 1 is removed by rotating the pressure adjustment component 2, thereby releasing the clamping of the second steel column 5 by the connecting components 1. This allows the second steel column 5 to be quickly removed, eliminating the need for manual installation and removal of multiple bolts and effectively improving the installation and removal efficiency of the first steel column 4 and the second steel column 5.

[0025] Further as Figure 2 and Figure 3As shown, it is worth noting that the connecting assembly 1 includes a liquid cylinder a106 fixed inside the inner cavity 6. Multiple liquid cylinders a106 are arranged in a ring. A rod 101 is inserted inside each liquid cylinder a106. A piston plate a104, which fits tightly against the inner wall of the liquid cylinder a106, is fixed to one end of the rod 101. A groove 103, which fits the end of the rod 101, is provided on the side of the second steel column 5. During use, liquid is introduced into the liquid cylinder a106, creating hydraulic pressure inside. This hydraulic pressure pushes multiple rods 101 to extend synchronously from inside the liquid cylinder a106. The end of cylinder a106 is inserted into groove 103, thereby clamping the second steel column 5 inserted into the mounting base 3 in a circumferential, multi-point uniform manner through multiple liquid cylinders a106. This securely connects the first steel column 4 and the second steel column 5 into a single unit, effectively improving the connection stability of the first steel column 4 and the second steel column 5. When it is necessary to remove it, the hydraulic pressure inside the inner cavity 6 and the liquid cylinder a106 is removed by rotating the pressure adjustment component 2, thereby releasing the clamping of the insertion rod 101 on the second steel column 5. This allows the second steel column 5 to be quickly removed, eliminating the need for manual installation and removal of multiple bolts and effectively improving the installation and removal efficiency of the first steel column 4 and the second steel column 5.

[0026] Further as Figure 3 As shown, it is worth noting that the ends of the multiple insertion rods 101 are all provided with arc-shaped ends 102; in actual operation, the arc-shaped ends 102 make it easy for the ends of the insertion rods 101 to be inserted into the grooves 103.

[0027] Further as Figure 3 As shown, it is worth noting that a spring 105 is installed inside the liquid cylinder a106. The two ends of the spring 105 are fixed to the side of the piston plate a104 and the side of the inner cavity 6, respectively. In actual operation, the spring 105 pulls the insertion rod 101 to reset, thereby improving the reset efficiency of the insertion rod 101 and facilitating the removal of the second steel column 5.

[0028] Further as Figure 1 and Figure 2As shown, it is worth noting that the pressure regulating assembly 2 includes a liquid cylinder b205 fixed to the outer wall of the mounting base 3 and communicating with the inner cavity 6. A nut sleeve 202 is fixed inside the end of the liquid cylinder b205 away from the mounting base 3. A threaded rod 201 inserted into the liquid cylinder b205 is connected to the internal thread of the nut sleeve 202. A piston plate b204 that fits tightly against the inner wall of the liquid cylinder b205 is fixed to one end of the threaded rod 201. In specific operation, the liquid cylinder b205 and the inner cavity 6 are filled with liquid, which can be hydraulic oil or water, etc. By rotating the threaded rod 201, the threaded rod 201 drives the piston plate b204 to move inside the liquid cylinder b205, thereby pressing the liquid inside the liquid cylinder b205 into the inner cavity 6 through the piston plate b204, so that the inner cavity 6 has hydraulic pressure, and the multiple insert rods 101 firmly clamp the second steel column 5.

[0029] This solution has the following working process: When connecting the first steel column 4 and the second steel column 5, the second steel column 5 is inserted into the mounting base 3. By rotating the threaded rod 201, the threaded rod 201 drives the piston plate b204 to move inside the liquid cylinder b205. Thus, the piston plate b204 forces the liquid inside the liquid cylinder b205 into the inner cavity 6, thereby creating hydraulic pressure inside the inner cavity 6. This hydraulic pressure then drives multiple insertion rods 101 to extend synchronously from inside the liquid cylinder a106. The ends of the liquid cylinder a106 are inserted into the groove 103, thereby using multiple liquid cylinders a106 to uniformly clamp the second steel column 5 inserted into the mounting base 3 at multiple points around the circumference. This securely connects the first steel column 4 and the second steel column 5 into one unit, effectively improving the connection stability of the first steel column 4 and the second steel column 5.

[0030] Further as Figure 5 As shown, it is worth noting that an end plate 203 is fixed on one end of the threaded rod 201 located outside the liquid cylinder b205, and a handle rod 206 is fixed on the side of the end plate 203; in actual operation, the threaded rod 201 can be easily rotated by the handle rod 206, which facilitates operation.

[0031] Further as Figure 1 and Figure 5 As shown, it is worth noting that a rubber sleeve 207 is fitted onto the surface of the handle 206, and the length of the rubber sleeve 207 is equal to the length of the handle 206. In actual operation, the rubber sleeve 207 increases the friction when gripping the handle 206, preventing slippage.

[0032] In summary: When the second steel column 5 is inserted into the mounting base 3, a certain amount of liquid is forced into the inner cavity 6 by the pressure adjustment component 2, thereby generating hydraulic pressure inside the inner cavity 6. This hydraulic pressure drives multiple sets of connecting components 1 to work synchronously, thus clamping the second steel column 5 inserted into the mounting base 3 at multiple points around its circumference. This securely connects the first steel column 4 and the second steel column 5 into one unit, effectively improving the connection stability of the first steel column 4 and the second steel column 5. When it is necessary to remove them, the hydraulic pressure inside the inner cavity 6 and the connecting components 1 is removed by rotating the pressure adjustment component 2, thereby releasing the clamping of the connecting components 1 on the second steel column 5. This allows the second steel column 5 to be quickly removed, eliminating the need for manual installation and removal of multiple bolts and effectively improving the installation and removal efficiency of the first steel column 4 and the second steel column 5.
