Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a beam-column connection node suitable for steel pipe columns and its processing device. Background Technology

[0002] For steel structures, firstly, steel structure buildings are green buildings, and steel structure construction is green construction, with a high degree of industrialization, short construction cycle, less on-site labor, high labor productivity, and easy quality assurance; secondly, construction occupies less land, can be dry-constructed, saves water, and generates less noise and dust; thirdly, steel is recyclable, reducing construction waste and environmental pollution; steel structures are a vital industry for people's livelihood, with light weight, high strength, and good plasticity, enabling continuous breakthroughs in building height and span, larger usable space, and superior seismic performance.

[0003] Currently, in the construction of steel structure beam-column connection nodes, steel columns are connected to the nodes by welding, the webs of steel beams are mainly connected to the nodes by bolts, and the flanges of steel beams are connected to the nodes by welding. However, achieving fixed connections through on-site penetration welding involves many procedures, requires a lot of time and manpower, is cumbersome to operate, and the quality of on-site welding cannot be guaranteed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a beam-column connection node and its processing device suitable for steel pipe columns. This invention facilitates both on-site construction and factory prefabrication, effectively improving the performance of the beam-column connection node.

[0005] The technical solution to the technical problem solved by this utility model is as follows: On the one hand, the embodiment of this utility model provides a beam-column connection node suitable for steel pipe columns, including a steel column and a steel beam, and also includes a core component. The core component includes a core steel pipe, a connecting plate and a first mating plate. The first mating plate is vertically arranged in the middle of the core steel pipe. The connecting plate is arranged at the top and bottom of the core steel pipe. The edge of the connecting plate is provided with a second mating plate. The outer side of the connecting plate is connected to the mating end of the steel column. The core steel pipe is connected to the steel beam through the first mating plate and the second mating plate. The steel beam is arranged between the two sets of second mating plates.

[0006] As an optimization, a vertical connector is provided on the connecting plate. The connector fits tightly against the inner wall of the mating end of the steel column, and the connector is connected to the steel column by high-strength bolts. By setting the connector, the connection strength with the steel column is enhanced, and on-site installation is facilitated.

[0007] As an optimization, the connector has a first bolt hole, and the butt joint of the steel column has a second bolt hole that mates with the first bolt hole. A nut is provided on the inner side of the connector. The high-strength bolt passes through the second bolt hole and the first bolt hole and is connected to the nut. By setting the first bolt hole, the second bolt hole, and the nut, the high-strength bolt is prevented from passing through the steel column horizontally. Long bolts are not required; only short bolts are needed to pass through the side walls of the steel column and the connector and connect to the nut. This allows all high-strength bolts to be located on the same horizontal plane, resulting in a high degree of standardization and aesthetics of the components. On-site full penetration welding is not required, facilitating on-site installation and reducing the labor intensity of workers.

[0008] As an optimization, the connector is made of a single piece of steel pipe. The single-piece steel pipe improves the strength of the joint and facilitates factory prefabrication, thereby increasing production efficiency.

[0009] As an optimization, the connector includes four sets of steel plates, with a reinforcing plate on the side of the connector away from the steel column. By including four sets of steel plates in the connector, it is easy to weld the nut to the inside of the steel plates, facilitating factory prefabrication. The reinforcing plate enhances the connection strength between the connector and the connecting plate, strengthens the shear resistance of the joint, and also facilitates factory prefabrication welding, ensuring that the connector is vertically welded to the connecting plate.

[0010] As an optimization, four sets of steel plates are arranged in a rectangle, with the ends of adjacent sets of steel plates connected to each other. This allows the four sets of steel plates to form a whole, combining the advantages of both steel plates and steel pipes, which not only improves the strength of the joint but also facilitates installation.

[0011] On the other hand, an embodiment of the present invention provides a processing device for beam-column connection nodes suitable for steel pipe columns, used to process the beam-column connection nodes suitable for steel pipe columns, including a processing table, a rotating worktable and a moving device on the top of the processing table, a positioning column that cooperates with a second docking plate on the rotating worktable, the moving device being disposed on one side of the rotating worktable, and an installation device being slidably disposed on the moving device.

[0012] As an optimization, the rotary table includes a turntable and locating pins. The turntable has insertion holes, and a rotating shaft is located at the center of its bottom. The rotating shaft is rotatably mounted on the machining table via tapered roller bearings. The locating pins are located on the machining table on one side of the turntable. Several sets of locating holes corresponding to the insertion holes are provided through the machining table, and the bottom of the locating pins passes through the insertion holes and is positioned within the locating holes. By setting up the turntable, rotating shaft, and tapered roller bearings, the turntable can support the core component and drive it to rotate stably. By setting up the insertion holes, locating pins, and locating holes, the position of the turntable can be fixed, thereby fixing the position of the core steel pipe and preventing the core steel pipe from rotating when the first mating plate is pushed, ensuring that the first mating plate is vertically welded to the side wall of the core steel pipe, and the through locating holes can prevent weld slag blockage.

[0013] As an optimization, the moving device includes a bracket, a motor, a lead screw, a limit rod, and a slider. Both ends of the lead screw are mounted on the bracket via bearings, and both ends of the limit rod are fixedly mounted on the bracket. The output end of the motor is connected to one end of the lead screw. The slider is connected to the lead screw via a thread, and slides on the limit rod through a limit hole. By setting up the bracket, the lead screw and limit rod can be supported; by setting up the motor, the slider can be driven to move horizontally via the lead screw; by setting up the limit rod, the slider can be prevented from rotating, allowing it to move horizontally stably; by setting up the lead screw and slider, they work together with the bracket to stably support and push the installation device.

[0014] As an optimization, the installation device includes push rods, shaft stops, mounting sleeves, and springs. Two sets of push rods are provided; one end of the push rod passes through the slider and connects to the shaft stop, while the other end passes through the bracket and connects to the mounting sleeve. The mounting sleeve has a slot on the side facing the rotary table. A baffle is provided on the push rod between the slider and the bracket, and the spring is located on the push rod between the baffle and the slider. By setting two sets of push rods, the first mating plate can be pushed onto the side wall of the core steel pipe, and the mounting sleeve can be prevented from rotating, ensuring that the first mating plate is vertically aligned with the core steel pipe. The shaft stop facilitates the installation of the push rod onto the slider, preventing it from falling off. The mounting sleeve and slot allow the first mating plate to be installed. The spring and baffle ensure that when the first mating plate abuts against the core steel pipe, the push rod and mounting sleeve press the first mating plate firmly against the core steel pipe, while allowing the slider to slide on the push rod, preventing damage to the motor and lead screw and providing time for the operator to shut down the motor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model is applicable to beam-column connection nodes for steel pipe columns. By setting a core component, it can connect steel columns and steel beams. By setting a core steel pipe, a connecting plate, and a first mating plate, it can be easily prefabricated in the factory to form standard components with a high degree of standardization, which facilitates on-site installation and reduces on-site construction time. The connecting plate can support both ends of the core steel pipe to prevent bulging deformation during use. The first mating plate can be connected to the web of the steel beam. By setting a second mating plate, it can be connected to the flange of the steel beam and can wrap the steel beam for easy installation.

[0017] This utility model relates to a processing device for beam-column connection nodes of steel pipe columns. By setting up a processing table, a rotating worktable and a moving device can be installed. The rotating worktable allows for the placement of the core steel pipe, connecting plate, and first butt plate, facilitating the rotational welding of the core steel pipe and connecting plate. This rotational welding of the core steel pipe and the first butt plate eliminates the need to move the core steel pipe, reducing the labor intensity of the workers. The positioning column allows the second butt plate to be fixed via bolt holes, thus determining the position of the core steel pipe and ensuring that the side wall of the core steel pipe is perpendicular to the moving direction of the moving device, thereby guaranteeing perpendicular welding of the first butt plate to the side wall of the core steel pipe. The moving device allows for easy movement of the first butt plate, placing it against the side wall of the core steel pipe, facilitating welding by a single operator, eliminating the need for additional support, and significantly improving processing efficiency. The installation device clamps the first butt plate, placing it against the side wall of the core steel pipe. Attached Figure Description

[0025] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Figures 1 to 2 As shown in the figure, in one embodiment of this utility model, a beam-column connection node suitable for steel pipe columns includes a steel column 1 and a steel beam 2, and also includes a core component 3. The core component 3 includes a core steel pipe 4, a connecting plate 5, and a first connecting plate 6. The first connecting plate 6 is vertically arranged in the middle of the core steel pipe 4. The connecting plate 5 is arranged at the top and bottom of the core steel pipe 4. The edge of the connecting plate 5 is provided with a second connecting plate 7. The connecting plate 5 and the second connecting plate 7 are integrally formed. The outer side of the connecting plate 5 is connected to the connecting end of the steel column 1. The core steel pipe 4 is connected to the steel beam 2 through the first connecting plate 6 and the second connecting plate 7. The first connecting plate 6 is provided with a third bolt hole, and the second connecting plate 7 is provided with a fifth bolt hole. The steel beam 2 is arranged between the two sets of second connecting plates 7. The web of the steel beam 2 is provided with a fourth bolt hole corresponding to the third bolt hole, and the flange of the steel beam 2 is provided with a sixth bolt hole corresponding to the fifth bolt hole. The steel beam 2 is arranged between the two sets of second connecting plates 7.

[0028] By setting the core component 3, the steel column 1 and the steel beam 2 can be connected; by setting the core steel pipe 4, the connecting plate 5 and the first docking plate 6, it is possible to facilitate factory prefabrication to form standard components with a high degree of standardization, which facilitates on-site installation and reduces on-site construction time. The connecting plate 5 can support both ends of the core steel pipe 4 to prevent the core steel pipe 4 from bulging and deforming during use. The first docking plate 6 can be connected to the web of the steel beam 2; by setting the second docking plate 7, it can be connected to the flange of the steel beam 2 and can wrap the steel beam 2 for easy installation.

[0029] A connector 8 is vertically mounted on the connecting plate 5. The connector 8 is tightly attached to the inner wall of the mating end of the steel column 1, and the connector 8 is connected to the steel column 1 by high-strength bolts 9. By setting the connector 8, the connection strength with the steel column 1 can be enhanced, and on-site installation can be facilitated.

[0030] The connector 8 has a first bolt hole 10, and the butt end of the steel column 1 has a second bolt hole 11 that mates with the first bolt hole 10. A nut 12 is provided on the inner side of the connector 8. The high-strength bolt 9 passes through the second bolt hole 11 and the first bolt hole 10 and is then connected to the nut 12. By providing the first bolt hole 10, the second bolt hole 11, and the nut 12, the high-strength bolt 9 is prevented from piercing the steel column. No long bolts are needed; only short bolts are required to pass through the side walls of the steel column 1 and the connector 8 and connect to the nut 12. This allows all the high-strength bolts 9 to be located on the same horizontal plane, resulting in a high degree of standardization and aesthetics. On-site full penetration welding is not required, facilitating on-site installation and reducing the labor intensity of workers.

[0031] Connector 8 is a one-piece molded steel pipe. The one-piece molded steel pipe can improve the strength of the joint and facilitate factory prefabrication, thereby improving production efficiency.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that, as Figure 3 and 4 As shown, the connector 8 includes four sets of steel plates, and a reinforcing plate 13 is provided on the side of the connector 8 away from the steel column 1. By including four sets of steel plates in the connector 8, the nut 12 can be easily welded to the inner side of the steel plates, facilitating factory prefabrication. By providing the reinforcing plate 13, the connection strength between the connector 8 and the connecting plate 5 can be enhanced, the shear resistance of the joint can be increased, and factory prefabrication welding can be facilitated, ensuring that the connector 8 is vertically welded to the connecting plate 5.

[0034] Four sets of steel plates form a rectangle, with the ends of adjacent sets of steel plates connected to each other. This allows the four sets of steel plates to form a whole, combining the advantages of both steel plates and steel pipes. It not only improves the strength of the joint but also facilitates installation.

[0035] During on-site construction, one steel column 1 is first installed. Then, the connector 8 at the bottom of the core component 3 is inserted into the top of the installed steel column 1. High-strength bolts 9 are passed through the second bolt hole 11 and the first bolt hole 10 to connect the high-strength bolts 9 with the nuts 12. This installation is quick and avoids piercing the steel column 1. Then, another steel column 1 is inserted into the connector 8 at the top of the core component 3 and fixed again with high-strength bolts 9, completing one set of column-to-column connections. After the two sets of column-to-column connections are completed, the steel beam 2 is hoisted up, and the end is inserted between the two sets of second mating plates 7. The web of the steel beam 2 is close to the first mating plate 6. The corresponding high-strength bolts are passed through the third bolt hole and the fourth bolt hole to fix the web of the steel beam 2 and the first mating plate 6. The flange of the steel beam 2 is close to the second mating plate 7. The corresponding high-strength bolts are passed through the fifth bolt hole and the sixth bolt hole to fix the flange of the steel beam 2 and the second mating plate 7, completing the beam-column installation. The overall construction speed is fast, on-site construction is convenient, and positioning can be easily performed before welding when welding reinforcement is required.

[0036] Figure 5 , Figure 6 This utility model discloses a processing device for beam-column connection nodes of steel pipe columns. The device is used to process the beam-column connection nodes of steel pipe columns. It includes a processing table 14, a rotating worktable 15 and a moving device 16 on the top of the processing table 14. The rotating worktable 15 is provided with a positioning column that cooperates with the second docking plate 7. The moving device 16 is located on one side of the rotating worktable 15, and an installation device 17 is slidably provided on the moving device 16.

[0037] By setting up the processing table 14, a rotary worktable 15 and a moving device 16 can be installed. The rotary worktable 15 can hold the core steel pipe 4, connecting plate 5, and first mating plate 6, facilitating the rotary welding of the core steel pipe 4 and connecting plate 5, and the rotary welding of the core steel pipe 4 and first mating plate 6 without moving the core steel pipe 4, reducing the labor intensity of workers. By setting up positioning columns, the second mating plate 7 can be fixed through bolt holes, thus determining the position of the core steel pipe 4, ensuring that the side wall of the core steel pipe 4 is perpendicular to the moving direction of the moving device 16, thereby ensuring that the first mating plate 6 is welded perpendicularly to the side wall of the core steel pipe 4. By setting up the moving device 16, the first mating plate 6 can be easily moved, allowing it to abut against the side wall of the core steel pipe 4, facilitating welding by workers, allowing for single-person operation without the need for others to fix it, and significantly improving processing efficiency. By setting up the mounting device 17, the first mating plate 6 can be clamped and abutted against the side wall of the core steel pipe 4.

[0038] The rotary worktable 15 includes a turntable 18 and a positioning pin 19. The turntable 18 has four sets of insertion holes 20 vertically arranged in a 90° pattern. A rotating shaft 21 is located at the center of the bottom of the turntable 18. The rotating shaft 21 is rotatably mounted on the machining table 14 via a tapered roller bearing 22. The positioning pin 19 is located on the machining table 14 on one side of the turntable 18. Several sets of positioning holes 23 corresponding to the insertion holes 20 are provided through the machining table 14. The bottom of the positioning pin 19 passes through the insertion hole 20 and is located in the positioning hole 23. By setting up a turntable 18, a rotating shaft 21, and a tapered roller bearing 22, the turntable 18 can support the core component 3 and drive the core component 3 to rotate stably. By setting up an insertion hole 20, a positioning pin 19, and a positioning hole 23, the position of the turntable 18 can be fixed, thereby fixing the position of the core steel pipe 4 and preventing the core steel pipe 4 from rotating when the first docking plate 6 is pushed, ensuring that the first docking plate 6 is vertically welded to the side wall of the core steel pipe 4, and the through positioning hole 23 can prevent welding slag from clogging.

[0039] The moving device 16 includes a bracket 24, a motor 25, a lead screw 26, a limiting rod 27, and a slider 28. Both ends of the lead screw 26 are mounted on the bracket 24 via bearings. Both ends of the limiting rod 27 are fixedly mounted on the bracket 24. The output end of the motor 25 is connected to one end of the lead screw 26. The slider 28 is connected to the lead screw 26 via a thread, and slides on the limiting rod 27 through a limiting hole. The bracket 24 supports the lead screw 26 and the limiting rod 27; the motor 25 drives the slider 28 to move horizontally via the lead screw 26; the limiting rod 27 prevents the slider 28 from rotating, ensuring stable horizontal movement; and the lead screw and slider 28 work together with the bracket 24 to stably support and push the mounting device 17.

[0040] The mounting device 17 includes a push rod 29, a shaft stop 30, a mounting sleeve 31, and a spring 32. The push rod 29 is provided in two sets. One end of the push rod 29 passes through the slider 28 and is connected to the shaft stop 30. The other end of the push rod 29 passes through the bracket 24 and is connected to the mounting sleeve 31. The mounting sleeve 31 has a slot 33 on the side facing the rotary table 15. A baffle 34 is provided on the push rod 29 between the slider 28 and the bracket 24. The spring 32 is provided on the push rod 29 between the baffle 34 and the slider 28. By setting two sets of push rods 29, the first docking plate 6 can be pushed onto the side wall of the core steel pipe 4, and the mounting sleeve 31 can be prevented from rotating, ensuring that the first docking plate 6 is vertically docked with the core steel pipe 4. By setting the shaft stop 30, the push rod 29 can be easily installed onto the slider 28, preventing the push rod 29 from falling off. By setting the mounting sleeve 31 and the slot 33, the first docking plate 6 can be installed. By setting the spring 32 and the baffle 34, when the first docking plate 6 abuts against the core steel pipe 4, it can be ensured that the push rod 29 and the mounting sleeve 31 press the first docking plate 6 tightly onto the core steel pipe 4, and the slider 28 can slide on the push rod 29, avoiding damage to the motor 25 and the lead screw 26, and providing time for the operator to shut down the motor 25.

[0041] During factory processing and use, the integrally formed connecting plate 5 and the second mating plate 7 are placed on the turntable 18. The positioning pins on the turntable 18 can be inserted into the fifth bolt holes on the second mating plate 7 for fixation. Then, the worker places the core steel pipe 4 onto the connecting plate 5 for welding. During welding, the positioning pin 19 is inserted into the insertion hole 20 and the positioning hole 23 to lock the turntable 18, allowing welding to be performed on one side of the core steel pipe 4 and the connecting plate 5. It should be noted that after locking, the side of the core steel pipe 4 is perpendicular to the push rod 29, and the side of the core steel pipe 4 corresponds to the mounting sleeve 31. To facilitate the subsequent welding of the first mating plate 6; after welding one side of the core steel pipe 4 and the connecting plate 5, the worker removes the positioning pin 19 and rotates the turntable to weld the other side; after welding all four sides, the worker inserts a set of first mating plates 6 into the slot 33, starts the motor 25, and the lead screw 26 drives the slider 28 to move. The slider 28 drives the push rod 29 and the mounting sleeve 31 to move horizontally towards the core steel pipe 4 until the first mating plate 6 abuts against the side wall of the core steel pipe 4. At this time, the push rod 29 stops moving. As the motor 25 continues to drive the slider 28, the spring 32 is in the slider 28 Compression begins under the action of the baffle 34. Before the spring is fully compressed, the operator turns off the motor 25. At this time, the spring 32 presses the first mating plate 6 against the side wall of the core steel pipe 4 through the push rod 29 and the mounting sleeve 31, which can prevent the welding from being weak. Then the operator can weld the first mating plate 6 and the core steel pipe 4. After completing the welding of one set of first mating plates 6, the motor 25 is started and reversed to make the mounting sleeve 31 detach from the welded first mating plate 6. Then another set of first mating plates 6 is inserted. Then the turntable 18 is rotated to change the side of the core steel pipe 4 and weld again. Note: The key feature is that, depending on the actual requirements of on-site construction, the four sides of the core steel pipe 4 can be selectively welded. Welding can be done on one side, two sides, three sides, or all four sides. After the first butt plate 6 is welded, the connecting plate 5 is removed from the positioning column, and another set of connecting plates 5 is placed on the turntable 18. The core steel pipe 4 is then inverted, and the connecting plates 5 are welded again. Finally, the workers can weld the connecting piece 8 onto the welded core component 3. After welding one side, the other side of the connecting piece 8 is welded by rotating the turntable 18. After welding all four sides, the beam-column connection node is completed. This utility model, applicable to the processing device for beam-column connection nodes of steel pipe columns, can quickly process beam-column connection nodes and ensure stable welding angles, preventing poor fit with the steel column 1 and steel beam 2, avoiding secondary processing on-site, and effectively improving the processing efficiency and performance of beam-column connection nodes.
