Description

Technical Field

[0001] This invention relates to the field of steel structure connection technology, and in particular to a steel structure node connection component. Background Technology

[0002] Steel structures are structural systems built primarily of steel, and are widely used in construction projects, industrial plants, and large stadiums. The main function of steel structure node connection components is to connect steel pipes or sections, ensuring effective force transmission between components and thus guaranteeing the stability of the entire steel structure system.

[0003] Existing steel structure technologies typically require workers to weld multiple steel members together on-site, and then reinforce the welded areas with three-dimensional angle steel structures as connecting components. However, repeated positioning and calibration are necessary during welding to ensure the perpendicularity between the steel members, resulting in low construction efficiency. Furthermore, angle steel structures occupy significant vertical space, cannot be neatly arranged on a flat surface, reduce space utilization, and are inconvenient to transport. Moreover, the rigid connection of individual steel members through welding reduces the buffer space during earthquakes, making the welded areas prone to fracture and leading to insufficient seismic performance of the structure. Summary of the Invention

[0004] In view of the above-mentioned prior art, the present invention provides a steel structure node connection component. The components of the connection component adopt a standardized modular design, which facilitates transportation, installation and commissioning. The mortise and tenon and bolt connections improve the seismic resistance and can be disassembled and reused.

[0005] To achieve the above objectives, the technical solution of this invention is implemented as follows: A steel structure node connection assembly includes an upper connecting plate, a lower connecting plate, a side connecting plate, and a vertical square tube. The upper and lower connecting plates are L-shaped. The side connecting plates are snapped onto each other by a tenon and mortise structure. The upper and lower connecting plates are provided with vertically aligned through holes. The vertical square tube is provided with a threaded hole. The side connecting plate is provided with a first through hole. A first bolt passes through the first through hole and connects to the threaded hole.

[0006] Furthermore, the upper connecting plate and the lower connecting plate are parallel, the upper edge and the lower edge of the side connecting plate are parallel, the side connecting plate is perpendicular to the upper connecting plate and the lower connecting plate, the upper side and the lower side of the side connecting plate are provided with a first latching protrusion, and the upper connecting plate and the lower connecting plate are provided with a first latching groove that mates with the first latching protrusion. The first latching protrusion and the first latching groove constitute the mortise and tenon structure.

[0007] Furthermore, there are two side connecting plates, which are located on both sides of the upper connecting plate and the lower connecting plate, respectively.

[0008] Furthermore, the depth of the first card slot is greater than the thickness of the side connecting plate, the width of the first card slot is 0.5-1.5mm greater than the width of the first card protrusion, and the outer edge of the first card slot is chamfered.

[0009] Furthermore, one end of the side connecting plate is provided with a second latching protrusion, and the other end of the side connecting plate is provided with a second latching groove that cooperates with the second latching protrusion.

[0010] Furthermore, the side connecting plate is provided with a second through hole, through which a second bolt for fixing the external steel structure can pass.

[0011] Furthermore, both the upper connecting plate and the lower connecting plate include a horizontal plate and a vertical plate, which are integrally formed and the connection between the horizontal plate and the vertical plate is a right-angle transition. Both the horizontal plate and the vertical plate are provided with several third through holes.

[0012] Furthermore, a fourth through hole is provided at the connection between the transverse plate and the longitudinal plate.

[0013] Furthermore, the vertical square tube includes an inner tube and an outer tube, the inner tube is inserted into the outer tube, the inner tube is fixedly connected to the outer tube, and the clearance between the through hole and the outer tube is 0.5-1.5mm.

[0014] Furthermore, the outer tube is composed of four steel plates, which are connected to the outer side wall of the inner tube, and the side edges of adjacent steel plates are separated from each other.

[0015] The beneficial effects of this invention are as follows: The standardized modular design of the upper connecting plate, lower connecting plate, and side connecting plate greatly improves the efficiency of factory pre-processing. Before assembly, the various components of the connecting assembly are planar structures, greatly facilitating the transportation of the connecting assembly. On-site, there is no need for numerous tedious installation procedures such as positioning and calibration, significantly increasing assembly speed. Through mortise and tenon joints and bolt connections, the connecting assembly possesses a certain degree of repair and energy dissipation capabilities. Under seismic action, the tenons and mortises at the joints can slide and rotate relative to each other, absorbing and dissipating seismic energy. This invention has a wide range of applications; when it is necessary to renovate, expand, or demolish a building, it can be easily disassembled and, after simple cleaning and maintenance, applied to other projects.

[0018] It should also be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element.

[0019] Please refer to the attached document. Figures 1-4This application provides a steel structure node connection assembly, including an upper connecting plate 1, a lower connecting plate 2, a side connecting plate 3, and a vertical square tube 4. The upper connecting plate 1 and the lower connecting plate 2 are L-shaped. The side connecting plate 3 is snapped onto the sides of the upper connecting plate 1 and the lower connecting plate 2 via a tenon and mortise structure. The upper connecting plate 1 and the lower connecting plate 2 have vertically aligned through holes. The vertical square tube 4 has a threaded hole 6. The side connecting plate 3 has a first through hole 5 aligned with the threaded hole 6. A first bolt 7 passes through the first through hole 5 and connects to the threaded hole 6. The upper connecting plate 1 and the lower connecting plate 2 are parallel, and the side connecting plate 3 is inserted between the upper connecting plate 1 and the lower connecting plate 2, snapping onto the upper connecting plate 1 and the lower connecting plate 2. At the same time, the side connecting plate 3 can be connected to the vertical square tube 4 via the first bolt 7. Under the action of the upper connecting plate 1, the lower connecting plate 2, and the vertical square tube 4, the two side connecting plates 3 are perpendicular to each other. Meanwhile, since both the upper connecting plate 1 and the lower connecting plate 2 are provided with through holes 20, after the vertical square tube 4 passes through the vertically aligned through holes, the vertical square tube 4 is also perpendicular to the two side connecting plates 3, thus forming a three-dimensional connecting assembly, and the three directions of the connecting assembly are perpendicular to each other. Therefore, by connecting the steel materials in the three directions to the side connecting plates 3 and the vertical square tube 4, the three steel materials are perpendicular to each other in the three-dimensional spatial structure.

[0020] Because the upper connecting plate 1, lower connecting plate 2, and side connecting plate 3 adopt a standardized modular design, these components can be produced quickly and accurately using modern advanced CNC machining equipment. Furthermore, a thickness of 20-50mm is sufficient to maintain a flat surface after processing, greatly improving the efficiency of factory pre-processing. Before assembly, each component of the connecting assembly has a planar structure, greatly facilitating the transportation of the connecting components.

[0021] On the construction site, workers only need to connect and fix standardized component modules using mortise and tenon joints according to design requirements, eliminating the need for numerous tedious installation procedures such as positioning and calibration, greatly improving assembly speed. Compared to traditional welding, it reduces time by 70%, with single-node assembly time ≤3 minutes, and offers better seismic resistance. It also reduces steel consumption by 15%-20% compared to fully welded structures, and standardized production ensures a scrap rate of <3%.

[0022] By employing mortise and tenon joints and bolt connections, the connecting components possess a certain degree of repair and energy dissipation capabilities. Under seismic loads, the tenons and mortises at the joints can slide and rotate relative to each other, absorbing and dissipating seismic energy. This invention has a wide range of applications. When buildings need to be renovated, expanded, or demolished, the components can be easily disassembled and, after simple cleaning and maintenance, applied to other projects, achieving resource recycling, reducing construction waste, and aligning with the concept of sustainable development. It is suitable for various prefabricated building scenarios, such as modular integrated housing, emergency rapid construction systems like medical cabins, and large-span spatial structures like stadiums.

[0023] Specifically, the upper connecting plate 1 and the lower connecting plate 2 are parallel, the upper edge and the lower edge of the side connecting plate 3 are parallel, and the side connecting plate 3 is perpendicular to the upper connecting plate 1 and the lower connecting plate 2. The upper and lower sides of the side connecting plate 3 are provided with first locking protrusions 8, and the upper connecting plate 1 and the lower connecting plate 2 are provided with first locking grooves 9 that mate with the first locking protrusions 8. The first locking protrusions 8 and the first locking grooves 9 constitute the mortise and tenon structure. The parallelism of the upper connecting plate 1 and the lower connecting plate 2, and the parallelism of the upper and lower edges of the side connecting plate 3, ensures that the assembled structural components fit tightly, improving stability. The first locking protrusions 8 and the first locking grooves 9 cooperate to form a mortise and tenon structure, which has a certain self-resetting ability and energy dissipation ability. Under seismic action, the tenons and mortises at the joints can slide and rotate relative to each other, absorbing and dissipating seismic energy. Steel structures inherently possess excellent corrosion resistance and durability. With appropriate anti-corrosion and fireproofing treatments, their service life is extended. The mortise and tenon joint method avoids problems such as weld corrosion and cracking that can occur with traditional welding, further improving structural durability and reducing later maintenance costs. The design of steel structure mortise and tenon joints possesses a unique aesthetic appeal. Their ingenious structural forms and refined processing techniques showcase the charm of traditional architectural culture while maintaining the simplicity and grandeur of modern architecture, adding a touch of cultural depth and artistic flair to the exterior and interior spaces of prefabricated houses.

[0024] Specifically, there are two side connecting plates 3, located on either side of the upper connecting plate 1 and the lower connecting plate 2. The two side connecting plates 3 are positioned in both the horizontal and vertical directions. After the steel structure is installed in the connecting assembly, the steel structure fits snugly against the side connecting plates 3 of the connecting assembly, improving the stability of the connection.

[0025] Specifically, the depth of the first slot 9 is greater than the thickness of the side connecting plate 3, and the width of the first slot 9 is 0.5-1.5mm greater than the width of the first protrusion 8. The outer edge of the first slot 9 is chamfered. A 0.5-1.5mm expansion gap is provided to ensure a stable fit between the first protrusion 8 and the first slot 9. The chamfer on the outer edge of the first slot 9 facilitates the insertion of the first protrusion 8 into the first slot 9.

[0026] Specifically, one end of the side connecting plate 3 is provided with a second latching protrusion 10, and the other end of the side connecting plate 3 is provided with a second latching groove 11 that cooperates with the second latching protrusion 10. The two side connecting plates 3 are connected to each other through the cooperation of the second latching protrusion 10 and the second latching groove 11, thereby improving the connection stability of the two side connecting plates 3.

[0027] Specifically, the side connecting plate 3 is provided with a second through hole 12, through which a second bolt for fixing the external steel structure can pass. After the steel is inserted into the connecting assembly, the second bolt passes through the second through hole 12 to connect with the steel, thereby improving the stability of the connection.

[0028] Specifically, both the upper connecting plate 1 and the lower connecting plate 2 include a horizontal plate 14 and a vertical plate 15, which are integrally formed. The connection between the horizontal plate 14 and the vertical plate 15 is a chamfered right angle transition. Both the horizontal plate 14 and the vertical plate 15 are provided with several third through holes 16. The horizontal plate 14 and the vertical plate 15 are cut from the same steel plate, making them a single unit. A chamfer is provided at the junction of the horizontal plate 14 and the vertical plate 15, resulting in a large connection area that allows for the provision of through holes. Third through holes 16 are also provided next to the through holes, allowing third bolts to be passed through and tightened, thus improving the connection strength.

[0029] Specifically, a fourth through hole 17 is provided at the connection between the transverse plate 14 and the longitudinal plate 15. After the fourth screw is passed through the fourth through hole 17, it is connected to the steel structure to improve the stability of the connection.

[0030] Specifically, the vertical square tube 4 includes an inner tube 18 and an outer tube 19. The inner tube 18 is inserted into the outer tube 19, and the inner tube 18 and the outer tube 19 are fixedly connected. The clearance between the through hole 20 and the outer tube 19 is 0.5-1.5mm. The clearance between the through hole 20 and the outer tube 19 is in the range of 0.5-1.5mm to ensure a stable connection between the vertical tube and the through hole 20. A steel structure can be inserted into the inner tube 18 and then tightened with bolts, or the steel structure can be welded to the vertical square tube 4.

[0031] Specifically, the outer tube 19 is composed of four steel plates, which are connected to the outer wall of the inner tube 18, and the side edges of adjacent steel plates are separated from each other. The side edges of the four steel plates are either connected or separated from each other, and in the separated state, they are inserted into the through hole 20 of the outer tube 19.

[0032] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention should be determined by the scope of the claims.
