Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to a self-locking modular steel structure connection node. Background Technology

[0002] Modular steel structure buildings refer to the spatial division of traditional houses into individual room-based building modules. The structural, maintenance, interior, and equipment piping systems are designed as a single unit, and the structural components, floor slabs, ceilings, and wall panels of each module are prefabricated and connected in the factory. These modules are then transported to the site for stacking and connection to form a complete building. Steel structure nodes are the connections between various steel components that make up the steel structure. The design and connection methods of these nodes are crucial to the overall performance and safety of the steel structure.

[0003] Currently, welding is the most common connection method for steel structures. Most shapes of structures can be connected by welds. It is simple to construct, saves labor and materials, and can be automated, resulting in high production efficiency. It does not require drilling, saving labor and time. However, after welding, it is difficult to disassemble the two steel structures and make it difficult to reuse them multiple times. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A self-locking modular steel structure connection node, comprising:

[0006] A crossbeam and a vertical beam are provided. The crossbeam is located to the right of the vertical beam. Two pairs of first through holes are provided on the right side of the vertical beam. A first outer shell is connected to the inner wall of the vertical beam near the first through holes. A second outer shell is connected to the outer side of the crossbeam near the first through holes. A third through hole is provided on the right side of the second outer shell. A second connecting rod is slidably connected inside the third through hole. One end of the second connecting rod is connected to a first connecting rod. A movable block is slidably connected to the outer side of the first connecting rod. A top block is connected to one end of the first connecting rod. One end of the top block penetrates the interior of the first through hole and extends into the interior of the first outer shell. A driving mechanism is provided at the other end of the second connecting rod. A positioning mechanism is provided inside the first outer shell.

[0007] In one possible implementation, the positioning mechanism includes a pair of lifting blocks that slide inside the first housing. A lifting rod is connected to the outside of the lifting blocks. One end of the lifting rod extends to the outside of the first housing. A first spring is sleeved on the outside of the lifting rod. One end of the first spring is fixedly connected to the lifting blocks, and the other end of the first spring is fixedly connected to the inner wall of the first housing.

[0008] The lifting block has a chamfer on its right side.

[0009] In one possible implementation, a fourth through hole is provided on the upper and lower sides of the first housing, and one end of the lifting rod passes through the interior of the fourth through hole.

[0010] In one possible implementation, the left and right side walls of the first housing are provided with sliding grooves, and a slider is slidably connected inside the sliding groove, with one end of the slider being fixedly connected to the lifting block.

[0011] In one possible implementation, the movable block has chamfers on both sides, and the cross-section of the movable block is set to a rhombus shape;

[0012] The top block is configured as a hemispherical shape.

[0013] In one possible implementation, the drive mechanism includes a screw connected to the other end of the second connecting rod, the outer side of the screw being threadedly connected to a threaded sleeve, the threaded sleeve being fixedly connected to the second housing, and one end of the screw extending to the outer side of the second housing and connected to a wheel.

[0014] In one possible implementation, two pairs of second through holes are provided on the right side of the vertical beam at the middle position of the two pairs of first through holes. Right-angle plates are connected to the left and right side walls of the horizontal beam near the pair of second through holes. A pair of positioning plates are connected to the front side of the right-angle plates. One end of the positioning plate passes through the interior of the second through hole and extends to the inside of the vertical beam. A sixth through hole is provided inside the positioning plate on the inside of the vertical beam. An L-shaped plate is slidably connected inside the sixth through hole.

[0015] The L-shaped plate has a pair of eighth through holes at its end, and a fixing mechanism is provided inside the eighth through holes.

[0016] In one possible implementation, the bottom positioning plate has a seventh through hole and a pair of fifth through holes inside. One end of the fifth through hole is connected to the sixth through hole, and the other end of the fifth through hole is connected to the seventh through hole. A side plate is connected inside the seventh through hole. A pair of insert rods are connected to one side of the side plate. One end of the insert rods extends into the interior of the fifth and eighth through holes. A pair of second springs are connected to the other side of the side plate. One end of the second springs is fixedly connected to the positioning plate. A handle is connected to the other side of the side plate at the middle position of the pair of second springs.

[0019] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0020] One end of the crossbeam is attached to the vertical beam, and four second connecting rods are inserted into the interior of the first housing. This causes the top block at one end of the second connecting rod to lift the upper and lower lifting blocks. As the top block continues to move deeper, the lifting block slides from the front to the back of the top block. Simultaneously, under the elastic action of the first spring, the lifting block abuts against the first connecting rod, thus limiting the second connecting rod and completing the connection between the crossbeam and the vertical beam. Conversely, to separate them, simply rotate the wheel to drive the second connecting rod forward, causing the lifting block to slide from the front to the back of the movable block. Then, pull the second connecting rod backward, and the lifting block slides from right to left across the back of the movable block and the front of the top block. Once the top block is no longer restrictive, the crossbeam and vertical beam can be separated. The disassembly and assembly process is simple and allows for reuse. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] This application provides a self-locking modular steel structure connection node, which solves the problems in the prior art.

[0033] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0034] Example 1:

[0035] The specific structure of this embodiment is as follows: Figures 1-6 As shown, a self-locking modular steel structure connection node includes:

[0036] A horizontal beam 1 and a vertical beam 4 are provided. The horizontal beam 1 is located to the right of the vertical beam 4. Two pairs of first through holes 7 are provided on the right side of the vertical beam 4. A first outer shell 3 is connected to the inner wall of the vertical beam 4 near the first through holes 7. A second outer shell 5 is connected to the outer side of the horizontal beam 1 near the first through holes 7. A third through hole 15 is provided on the right side of the second outer shell 5. A second connecting rod 16 is slidably connected inside the third through hole 15. One end of the second connecting rod 16 is connected to a first connecting rod 11. A movable block 14 is slidably connected to the outer side of the first connecting rod 11. One end of the first connecting rod 11 is connected to a top block 12. One end of the top block 12 passes through... The first through hole 7 extends into the interior of the first outer shell 3. The other end of the second connecting rod 16 is provided with a driving mechanism. The interior of the first outer shell 3 is provided with a positioning mechanism. By providing the positioning mechanism, it is convenient to connect the crossbeam 1 and the vertical beam 4. By providing the driving mechanism, the second connecting rod 16 is driven to go further forward, so that the lifting block 9 slides from the front of the movable block 14 to the back. At this time, the second connecting rod 16 is pulled out backward. The lifting block 9 slides from right to left past the back of the movable block 14 and the front of the top block 12. After the top block 12 is no longer restricted, the crossbeam 1 and the vertical beam 4 can be separated.

[0037] In some examples, the positioning mechanism includes a pair of lifting blocks 9 sliding inside the first housing 3. Lifting rods 6 are connected to the outside of the lifting blocks 9. One end of the lifting rods 6 extends to the outside of the first housing 3. A first spring 13 is sleeved on the outside of the lifting rods 6. One end of the first spring 13 is fixedly connected to the lifting blocks 9, and the other end of the first spring 13 is fixedly connected to the inner wall of the first housing 3. When the second connecting rod 16 is inserted into the inside of the first housing 3, the top block 12 at one end of the second connecting rod 16 lifts the upper and lower lifting blocks 9. As the top block 12 continues to penetrate, the lifting blocks 9 slide from the front of the top block 12 to the back of the top block 12. At the same time, under the elastic action of the first spring 13, the lifting blocks 9 abut against the first connecting rod 11, thereby limiting the second connecting rod 16 and completing the connection between the crossbeam 1 and the vertical beam 4.

[0038] The lifting block 9 has a chamfer on its right side. By having a chamfer on the right side of the lifting block 9, it is convenient for the lifting block 9 to slide along the left and right sides of the movable block 14 and along the outside of the top block 12.

[0039] In some examples, the upper and lower sides of the first housing 3 are provided with fourth through holes 20, and one end of the lifting rod 6 passes through the interior of the fourth through hole 20, so that the lifting rod 6 can slide along the interior of the fourth through hole 20.

[0040] In some examples, the left and right side walls of the first outer shell 3 are provided with sliding grooves 21. A slider 10 is slidably connected inside the sliding groove 21. One end of the slider 10 is fixedly connected to the lifting block 9. When the top block 12 lifts the upper and lower lifting blocks 9, it drives the slider 10 to slide along the inside of the sliding groove 21. Under the connection between the slider 10 and the sliding groove 21, it is beneficial to increase the stability of the lifting block 9 during the lifting process.

[0041] In some examples, both sides of the movable block 14 are chamfered, and the cross-section of the movable block 14 is set to a rhombus shape, which is conducive to fitting the right side of the lifting block 9 and making it easy for the lifting block 9 to slide along the left and right sides of the movable block 14.

[0042] The top block 12 is set in a hemispherical shape. By setting the top block 12 in a hemispherical shape, it is easier to fit the right side of the lifting block 9, and the lifting block 9 can slide along the outside of the top block 12.

[0043] In some examples, the drive mechanism includes a screw 18 connected to the other end of the second connecting rod 16. A threaded sleeve 17 is threadedly connected to the outer side of the screw 18. The threaded sleeve 17 is fixedly connected to the second housing 5. One end of the screw 18 extends to the outer side of the second housing 5 and is connected to a rotating wheel 19. When it is necessary to separate the crossbeam 1 and the vertical beam 4, the rotating wheel 19 is rotated to drive the second connecting rod 16 to go further forward, so that the lifting block 9 slides from the front of the movable block 14 to the back. At this time, the second connecting rod 16 is pulled out backward, and the lifting block 9 slides from right to left across the back of the movable block 14 and the front of the top block 12. After the top block 12 is no longer restricted, the crossbeam 1 and the vertical beam 4 can be separated.

[0044] By adopting the above technical solution:

[0045] One end of the crossbeam 1 is attached to the vertical beam 4, and four second connecting rods 16 are inserted into the interior of the first outer casing 3. This causes the top block 12 at one end of the second connecting rod 16 to lift the upper and lower lifting blocks 9. As the top block 12 continues to move deeper, the lifting block 9 slides from the front of the top block 12 to the back of the top block 12. At the same time, under the elastic action of the first spring 13, the lifting block 9 abuts against the first connecting rod 11, thus limiting the second connecting rod 16 and completing the connection between the crossbeam 1 and the vertical beam 4. Conversely, when it is necessary to separate them, simply rotate the rotating wheel 19 to drive the second connecting rod 16 to move further forward, causing the lifting block 9 to slide from the front of the movable block 14 to the back. Then, pull the second connecting rod 16 out backward, and the lifting block 9 slides from right to left across the back of the movable block 14 and the front of the top block 12. After the top block 12 is no longer restricted, the crossbeam 1 and the vertical beam 4 can be separated. The disassembly and assembly process is simple and can be reused.

[0046] Example 2:

[0047] The specific structure of this embodiment is as follows: Figure 7 As shown, two pairs of second through holes 8 are provided on the right side of the vertical beam 4, located in the middle of the two pairs of first through holes 7. Right angle plates 32 are connected to the left and right side walls of the horizontal beam 1 near the pair of second through holes 8. A pair of positioning plates 25 are connected to the front side of the right angle plates 32. One end of the positioning plate 25 passes through the interior of the second through hole 8 and extends to the inside of the vertical beam 4. A sixth through hole 26 is provided inside the positioning plate 25 located inside the vertical beam 4. An L-shaped plate 2 is slidably connected inside the sixth through hole 26.

[0048] The L-shaped plate 2 has a pair of eighth through holes 31 at its end. The eighth through holes 31 are equipped with a fixing mechanism. The positioning mechanism fixes the horizontal beam 1 and the vertical beam 4, while the positioning plate 25 is inserted into the vertical beam 4. Then, the L-shaped plate 2 is inserted into the positioning plates 25 on the upper and lower sides in sequence to limit the positioning plates 25 and further improve the connection stability between the horizontal beam 1 and the vertical beam 4.

[0049] In some examples, the bottom positioning plate 25 has a seventh through hole 29 and a pair of fifth through holes 22 inside. One end of the fifth through hole 22 is connected to the sixth through hole 26, and the other end of the fifth through hole 22 is connected to the seventh through hole 29. A side plate 27 is connected inside the seventh through hole 29. A pair of insert rods 30 are connected to one side of the side plate 27. One end of the insert rod 30 extends into the interior of the fifth through hole 22 and the eighth through hole 31. A pair of second springs 23 are connected to the other side of the side plate 27. One end is fixedly connected to the positioning plate 25, and the other side of the side plate 27 is connected to a handle 28 at the middle position of a pair of second springs 23. After the L-shaped plate 2 is inserted into the positioning plates 25 on the upper and lower sides in sequence, the insertion rod 30 is inserted into the eighth through hole 31 by the elastic action of the second spring 23, thus completing the positioning of the L-shaped plate 2 and preventing it from falling off. Conversely, before inserting the L-shaped plate 2 into the positioning plate 25, the insertion rod 30 is taken out from the eighth through hole 31 by pulling the handle 28.

[0050] In some examples, a pair of stiffening plates 24 are connected to the back side of the right-angle plate 32. By setting the stiffening plates 24, the strength of the right-angle plate 32 can be increased, and deformation can be avoided.

[0051] In some examples, the stiffening plate 24 is set in the shape of a right triangle, and both right-angled plates of the stiffening plate 24 are fixedly connected to the right-angled plate 32. The right-angled triangle shape is stable, which helps to increase the strength of the right-angled plate 32 and prevent it from deforming.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
