Description

Technical Field

[0001] This utility model relates to the field of cast steel nodes, specifically a movable irregular cast steel node for steel structures. Background Technology

[0002] Cast steel joints are a type of steel structure connection solution that achieves high customization, excellent mechanical properties, and aesthetic appeal through precision design and casting technology. They are widely used in key load-bearing components of large-span spatial structures, bridges, and large public buildings.

[0003] Chinese patent application number CN202022261609.8 discloses a cast steel node with a positioning structure. This invention solves the problem that the conventional method of inserting the steel pipes to be connected into the cast steel node and then fixing them with bolts is not feasible. Because the stability of the splicing between the steel pipes needs to be ensured, the dimensional fit between the steel pipes and the cast steel node is relatively high, which makes it inconvenient for the operator to align the steel pipes and the cast steel node when splicing them, thus reducing the efficiency of splicing between the steel pipes and the cast steel node. This invention improves the efficiency of splicing and aligning the main body of the cast steel node and the connecting pipe, thereby improving the overall work efficiency.

[0004] However, most existing irregular cast steel nodes for steel structures are integrally formed, and the angle of the cast steel body is difficult to adjust according to the angle of the building, making them inflexible and inconvenient to use. Furthermore, for nodes with complex structures or limited internal space, integral casting may result in some structures that are difficult to complete. Therefore, a movable irregular cast steel node for steel structures is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, most existing irregular cast steel nodes for steel structures are integrally formed, and the angle of the cast steel body is difficult to adjust according to the angle of the building, making it inflexible and inconvenient to use. Furthermore, for nodes with complex structures or limited internal space, integral casting may present some structural problems that are difficult to complete. This utility model proposes a movable irregular cast steel node for steel structures.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a movable steel structure irregular cast steel node, including an irregular cast steel node body; the irregular cast steel node body is externally connected to a movable component, and the irregular cast steel node body is externally connected to an assembly component.

[0007] The movable component includes a pair of connecting rings, which are fixedly connected to the outer wall of the main body of the irregular cast steel node. A connecting plate is fixedly connected to the outer wall of the pair of connecting rings. A damping shaft one is rotatably connected to the outer side of the upper connecting plate. A threaded sleeve is fixedly connected to the outer side of the damping shaft one. A flange is fixedly connected to the outer side of the threaded sleeve. A threaded head is threadedly connected to the inner side of the threaded sleeve. An irregular cast steel node movable body is fixedly connected to the outer side of the threaded head. A second damping shaft two is rotatably connected to the outer side of the lower connecting plate. A hydraulic cylinder is fixedly connected to the outer side of the second damping shaft two.

The third damping shaft three is fixedly connected to the output rod.

[0008] By setting up movable components, the hydraulic cylinder drives the output rod to extend and retract. When the hydraulic cylinder drives the output rod to extend, it pushes the movable body of the irregular cast steel node upward, allowing the unrestricted end of the movable body to move upward. Conversely, when the hydraulic cylinder drives the output rod to retract, it pulls the movable body of the irregular cast steel node downward, allowing the unrestricted end of the movable body to move downward. This allows for flexible adjustment of the angle between the movable body of the irregular cast steel node and the main body of the irregular cast steel node, making it suitable for nodes with complex structures or limited internal space, and enabling the completion of more difficult structures.

[0009] The threaded sleeve and threaded head facilitate the installation and disassembly of the irregular cast steel node movable body and the irregular cast steel node body, and make it easy to replace and install irregular cast steel node movable bodies of different diameters according to different needs. The flange and locking screw improve the firmness of the connection between the irregular cast steel node movable body and the threaded sleeve.

[0010] Preferably, the threaded sleeve is rotatably connected to the upper connecting piece, the hydraulic cylinder is rotatably connected to the lower connecting piece, and the output rod is rotatably connected to the fixed piece.

[0011] Preferably, the pair of connecting rings are symmetrically distributed vertically, and the connecting pieces are also symmetrically distributed vertically.

[0012] Preferably, the flange and one end of the irregular cast steel node movable body are detachably connected by a locking screw, the locking screw being threadedly connected to the flange and the irregular cast steel node movable body.

[0013] Preferably, the assembly includes a flange, which is fixedly connected to the upper and lower ends of the irregular cast steel node body, and the outer end of the flange has a screw hole.

[0014] Preferably, the outer end of the irregular cast steel node movable body is fixedly connected to a flange two, and the outer end of the flange two is provided with a screw hole two.

[0015] Preferably, the internal thread of the screw hole one is connected to a bolt one, and the internal thread of the screw hole two is connected to a bolt two.

[0016] The advantages of this utility model are:

[0017] 1. This utility model, by setting up a movable component, uses a hydraulic cylinder to drive the output rod to extend and retract. When the hydraulic cylinder drives the output rod to extend, it pushes the movable body of the irregular cast steel node upward, allowing the unrestricted end of the movable body to move upward. Conversely, when the hydraulic cylinder drives the output rod to retract, it pulls the movable body of the irregular cast steel node downward, allowing the unrestricted end of the movable body to move downward. This allows for flexible adjustment of the angle between the movable body of the irregular cast steel node and the main body of the irregular cast steel node, making it suitable for nodes with complex structures or limited internal space, and enabling the completion of more difficult structures.

By setting a threaded sleeve and a threaded head, this utility model can facilitate the installation and disassembly of the movable body of the irregular cast steel node and the main body of the irregular cast steel node, and facilitate the replacement and installation of irregular cast steel node movable bodies of different diameters according to different needs.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a movable, irregularly shaped cast steel joint for steel structures. (Refer to...) Figures 1-4 A movable steel structure irregular cast steel node includes an irregular cast steel node body 1; the irregular cast steel node body 1 is externally connected to a movable component 2, and the irregular cast steel node body 1 is externally connected to an assembly component 3.

[0028] The active component 2 includes a pair of connecting rings 201, which are fixedly connected to the outer wall of the irregular cast steel node body 1. A connecting piece 202 is fixedly connected to the outer wall of the pair of connecting rings 201. A damping shaft 203 is rotatably connected to the outer side of the upper connecting piece 202. A threaded sleeve 204 is fixedly connected to the outer side of the damping shaft 203. A flange 205 is fixedly connected to the outer side of the threaded sleeve 204. A threaded head 206 is threadedly connected inside the threaded sleeve 204. An irregular cast steel node is fixedly connected to the outer side of the threaded head 206. The cast steel node movable body 207 has a damping shaft 208 externally rotatably connected to the lower connecting piece 202. A hydraulic cylinder 209 is fixedly connected to the external side of the damping shaft 208. An output rod 210 is fixedly connected to the output end of the hydraulic cylinder 209. A fixing ring 211 is fixedly connected to the external side of the irregular cast steel node movable body 207. A fixing piece 212 is fixedly connected to the lower end of the fixing ring 211. A damping shaft 213 is rotatably connected to the external side of the fixing piece 212. The damping shaft 213 is fixedly connected to the output rod 210.

[0029] By setting the movable component 2, the hydraulic cylinder 209 drives the output rod 210 to extend and retract. When the hydraulic cylinder 209 drives the output rod 210 to extend, it will push the irregular cast steel node movable body 207 upward, so that the unrestricted end of the irregular cast steel node movable body 207 can move upward. Conversely, when the hydraulic cylinder 209 drives the output rod 210 to retract, it will pull the irregular cast steel node movable body 207 downward, so that the unrestricted end of the irregular cast steel node movable body 207 can move downward. This allows for flexible adjustment of the angle between the irregular cast steel node movable body and the irregular cast steel node body, making it suitable for nodes with complex structures or limited internal space, and enabling the completion of more difficult structures.

[0030] Damping shaft 1 203, damping shaft 208, and damping shaft 3 213 respectively improve the damping properties of threaded sleeve 204, hydraulic cylinder 209, and output rod 210, thereby improving the overall stability of the device.

[0031] The threaded sleeve 204 and threaded head 206 facilitate the installation and disassembly of the irregular cast steel node movable body 207 and the irregular cast steel node body 1, and make it convenient to replace and install irregular cast steel node movable bodies 207 of different diameters according to different needs. The flange 301 and locking screw 214 improve the firmness of the connection between the irregular cast steel node movable body 207 and the threaded sleeve 204.

[0032] Reference Figures 1-4 The threaded sleeve 204 is rotatably connected to the upper connecting piece 202, the hydraulic cylinder 209 is rotatably connected to the lower connecting piece 202, and the output rod 210 is rotatably connected to the fixed piece 212.

[0033] Reference Figures 1-4 A pair of connecting rings 201 are symmetrically distributed vertically, and connecting pieces 202 are symmetrically distributed vertically.

[0034] Reference Figures 1-4 The flange 205 and one end of the irregular cast steel node movable body 207 are detachably connected by a locking screw 214. The locking screw 214 is threadedly connected to the flange 205 and the irregular cast steel node movable body 207.

[0035] Reference Figures 1-4 The assembly component 3 includes a flange 301, which is fixedly connected to the upper and lower ends of the irregular cast steel node body 1. The outer end of the flange 301 is provided with a screw hole 302.

[0036] Reference Figures 1-4 The outer end of the irregular cast steel node movable body 207 is fixedly connected to a flange 303, and the outer end of the flange 303 is provided with a bolt hole 304.

[0037] Reference Figures 1-4Bolt 305 is connected to the internal thread of screw hole 302, and bolt 306 is connected to the internal thread of screw hole 304.

[0038] By setting flange 301, when assembling multiple irregular cast steel node bodies 1, the flanges 301 of two adjacent irregular cast steel node bodies 1 are aligned and then locked with bolt 305. When assembling two irregular cast steel node movable bodies 207, the flanges 303 of two adjacent irregular cast steel node movable bodies 207 are aligned and then bolt 306 is locked, which facilitates the modular installation of irregular cast steel nodes.

[0039] Working principle: The hydraulic cylinder 209 drives the output rod 210 to extend and retract. When the hydraulic cylinder 209 drives the output rod 210 to extend, it will push the irregular cast steel node movable body 207 upward, so that the unrestricted end of the irregular cast steel node movable body 207 can move upward. Conversely, when the hydraulic cylinder 209 drives the output rod 210 to retract, it will pull the irregular cast steel node movable body 207 downward, so that the unrestricted end of the irregular cast steel node movable body 207 can move downward. This allows for flexible adjustment of the angle between the irregular cast steel node movable body and the irregular cast steel node body, making it suitable for nodes with complex structures or limited internal space, and enabling the completion of more difficult structures.

[0040] Damping shaft 1 203, damping shaft 208, and damping shaft 3 213 respectively improve the damping properties of threaded sleeve 204, hydraulic cylinder 209, and output rod 210, thereby improving the overall stability of the device.

[0041] The threaded sleeve 204 and threaded head 206 facilitate the installation and disassembly of the irregular cast steel node movable body 207 and the irregular cast steel node body 1, and make it convenient to replace and install irregular cast steel node movable bodies 207 of different diameters according to different needs. The flange 301 and locking screw 214 improve the firmness of the connection between the irregular cast steel node movable body 207 and the threaded sleeve 204.

[0042] When assembling multiple irregular cast steel node bodies 1, align the flanges 301 of two adjacent irregular cast steel node bodies 1, and then tighten them with bolts 305. When assembling two irregular cast steel node movable bodies 207, align the flanges 303 of two adjacent irregular cast steel node movable bodies 207, and then tighten bolts 306. This facilitates the modular installation of irregular cast steel nodes.
