Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a steel structure connection joint. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components are usually connected by welds, bolts, or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges, and other fields. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance. Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. It has good homogeneity and isotropy, belonging to an ideal elastic body, best conforming to the basic assumptions of general engineering mechanics. It also has good plasticity and toughness, allowing for large deformation and excellent resistance to dynamic loads. Construction time is short, and its high degree of industrialization allows for highly mechanized and specialized production.

[0003] During the construction of steel structures, the connection between two H-beams requires a steel structure connector. In the existing connection process, each steel structure and connector is connected separately. After a period of use, the loosening of bolts can cause the individual steel structure to loosen, affecting the overall stability. Furthermore, prolonged exposure to air and slow oxidation can also lead to bolt loosening, affecting safety. Therefore, we propose a steel structure connector. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a steel structure connecting joint that solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure connecting joint, comprising a first support frame, a stabilizing block fixedly fitted inside the first support frame, an H-shaped steel movably fitted inside the inner cavity of the first support frame, a second support frame disposed behind the first support frame, a positioning ring fixedly supported in front of the second support frame, an annular limiting groove adapted to the positioning ring being formed inside the H-shaped steel, a support fan fixedly supported outside the first support frame, and a support block located inside the support fan fixedly supported outside the first support frame.

[0006] Optionally, the first support frame has a connecting block fixedly supported inside, the inner side of the H-shaped steel is attached to the outer side of the connecting block, and the outer side of the stabilizing block is attached to the H-shaped steel.

[0008] Optionally, a sealing sleeve is fixedly installed on the outside of the support fan and the positioning ring, a sealing sheet is movably installed on the outside of the sealing sleeve, and an air extraction pipe is fixedly supported inside the sealing sheet.

[0009] Optionally, the internal fixed support of the suction pipe has two sealing rings, one of which has a sealing spring connected to its outer side, and the end of the sealing spring is connected to a sealing plate, which fits against the other sealing ring.

[0010] Optionally, the second support frame is internally fitted with connecting bolts, the inner side of which is bolted into the inner cavity of the connecting block.

[0011] Optionally, the sealing sleeve is located outside the locking bolt or locking nut, and the front-to-back length of the sealing sleeve is greater than the length of the locking bolt and locking nut extending to the outside of the positioning ring and the support fan.

[0012] Optionally, the inner side of the extraction pipe is provided with an air exchange groove, the vertical cross-section of the sealing ring is annular, and the diameter of the sealing piece is greater than the inner diameter of the sealing ring.

[0013] This invention provides a steel structure connecting joint, which has the following beneficial effects:

[0014] This steel structure connecting joint, through the setting of the first support frame, has a stabilizing block fixedly installed inside the first support frame, which can help to position the H-beam and prevent the H-beam from shaking. At the same time, an annular groove is opened on the outside of the H-beam, which can be used in conjunction with the second support frame and the positioning ring to achieve a stable connection between the four H-beams and the first support frame, avoiding the instability of the individual H-beams. The overall linkage can effectively improve the overall stability.

[0015] A support fan is installed on the outside of the first support frame, and a support block is fixedly installed on the outside of the first support frame to help to provide stable support for the positioning ring. The locking bolts and locking nuts play an auxiliary connection role, thereby ensuring the stability and tightness of the connection between the second support frame and the first support frame. At the same time, a connecting block is fixedly installed in the middle of the inside of the first support frame, so that the connecting bolts on the inside of the second support frame can be moved to assist in completing the connection between the second support frame and the first support frame.

[0016] A sealing sleeve is installed on the outside of the support fan and positioning ring, located outside the locking bolt and locking nut. The sealing sleeve can be sealed by the cooperation of the sealing plate. At the same time, an air extraction pipe is fixedly installed inside the sealing plate. By using the cooperation of the sealing ring and sealing spring inside the air extraction pipe with the sealing plate, the inner cavity of the sealing sleeve can be kept in a low air pressure state after air extraction, which can ensure the sealing effect of the sealing plate and prevent corrosion.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Please see Figures 1 to 6This invention provides a technical solution: a steel structure connecting joint, including a first support frame 1, with a stabilizing block 3 fixedly fitted inside the first support frame 1. The stabilizing block 3 assists in supporting an H-shaped steel 2 and prevents the H-shaped steel 2 from swaying. The H-shaped steel 2 is movably fitted inside the cavity of the first support frame 1, and an annular groove is formed on the inner side of the H-shaped steel 2 to engage with a positioning ring 8. A second support frame 7 is provided behind the first support frame 1, which seals the first support frame 1 to ensure the stability of the seal. A positioning ring 8 is fixedly supported in front of the second support frame 7, which assists in stabilizing and engaging the H-shaped steel 2. To ensure the stability of the H-shaped steel 2, an annular limiting groove adapted to the positioning ring 8 is provided inside the H-shaped steel 2. The positioning ring 8 can simultaneously link multiple directions of the H-shaped steel 2, ensuring the overall stability of the H-shaped steel 2, preventing the loosening of individual H-shaped steel 2, and effectively strengthening the overall integrity. The first support frame 1 is externally fixedly supported by a support fan 6. The support fan 6 plays a role in assisting stability and connecting the positioning ring 8, ensuring the overall stability of the positioning ring 8. The outer side of the first support frame 1 is fixedly supported by a support block 5 located inside the support fan 6. The support block 5 cooperates in supporting and limiting the positioning ring 8, and assists the support fan 6 in stabilizing the positioning ring 8.

[0026] The first support frame 1 has a connecting block 4 fixedly supported inside. The inner side of the H-shaped steel 2 is attached to the outer side of the connecting block 4, and the outer side of the stabilizing block 3 is attached to the H-shaped steel 2. The connecting block 4 can play an auxiliary connection role and can cooperate to connect the first support frame 1 and the second support frame 7. At the same time, the outer side of the H-shaped steel 2 is attached to the connecting block 4.

[0027] The inner side of the positioning ring 8 is supported on the outer side of the support block 5. The support block 5 can help to provide stable support for the positioning ring 8 and ensure the stability of the support. The radius of the positioning ring 8 is the same as the radius of the support fan 6. The positioning ring 8 and the support fan 6 are internally fitted with locking bolts 10, and the locking bolts 10 are externally fixed with locking nuts 11.

[0028] A sealing sleeve 12 is fixedly installed on the outside of the support fan 6 and the positioning ring 8 respectively. A sealing plate 13 is movably installed on the outside of the sealing sleeve 12. An air extraction pipe 14 is fixedly supported inside the sealing plate 13. The sealing sleeve 12 and the sealing plate 13 can cooperate to form a sealed space, thereby helping to fully protect the locking bolt 10 and the locking nut 11, and preventing corrosion at the connection position of the locking bolt 10 and the locking nut 11, which would affect the overall safety and stability.

[0029] The internal fixed support of the exhaust pipe 14 has two sealing rings 15. A sealing spring 16 is connected to the outside of one of the sealing rings 15. A sealing plate 17 is connected to the end of the sealing spring 16. The sealing plate 17 fits against the other sealing ring 15. The exhaust pipe 14 can play a role in unidirectional flow restriction, thereby assisting in exhaust.

[0030] The second support frame 7 has a connecting bolt 9 installed inside. The inner side of the connecting bolt 9 is fitted into the inner cavity of the connecting block 4. The connecting bolt 9 can be used to connect the second support frame 7 and the first support frame 1, ensuring the stability of the second support frame 7.

[0031] The sealing sleeve 12 is located outside the locking bolt 10 or locking nut 11, and the front-to-back length of the sealing sleeve 12 is greater than the length of the locking bolt 10 and locking nut 11 extending to the outside of the positioning ring 8 and the support fan 6.

[0032] The inner side of the extraction pipe 14 is provided with an air exchange groove, the vertical cross-section of the sealing ring 15 is annular, and the diameter of the sealing piece 17 is greater than the inner diameter of the sealing ring 15.

[0033] In summary, when using this steel structure connecting joint, firstly, the four H-shaped steels 2 to be installed are inserted into the inner cavity of the first support frame 1 from four directions, so that the inner side of the H-shaped steel 2 fits against the outer side of the connecting block 4. Then, the second support frame 7 drives the positioning ring 8 to fit against the outside of the first support frame 1, so that the positioning ring 8 is supported on the outside of the support block 5, and the front of the positioning ring 8 and the rear of the support fan 6 fit against each other. At the same time, by rotating the connecting bolt 9, the initial positioning of the second support frame 7 and the first support frame 1 can be completed, so that the second support frame 7 is completely fitted against the first support frame 1. At the same time, the positioning ring 8 will be locked inside the four H-shaped steels 2. By using the cooperation of the positioning ring 8, the first support frame 1 and the second support frame 7, the H-shaped steels 2 can be stably fixed. Then, the locking bolt 10 is used to lock the support fan 6. The rear of 6 passes through the support fan 6 and the positioning ring 8, extending to the rear of the positioning ring 8. The locking bolt 10 is then fixed using the locking nut 11. The sealing plate 13 is then placed outside the sealing sleeve 12, assisting in sealing the sleeve 12. Simultaneously, the connection bolt 9 and the connection point of the second support frame 7 are fully welded, allowing the inner side of the sealing plate 13 to enter the interior of the sealing sleeve 12. An air extraction device is then placed outside the air extraction pipe 14 to extract air from the inner cavity of the sealing sleeve 12 and the sealing plate 13. When the air pressure inside the sealing sleeve 12 is lower than the outside pressure, the sealing spring 16, in conjunction with the supporting sealing plate 17, adheres to the sealing ring 15, effectively preventing outside air from entering the inner cavity of the sealing sleeve 12, thus preventing the locking bolt 10 and locking nut 11 from corroding and loosening.
