Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of assembled buildings, and in particular to an assembled building steel structure connecting component. Background Art
[0002] Although the traditional welding connection method can achieve a strong connection strength, it has obvious disadvantages. At the construction site, welding operations have high requirements on the environment. In case of humid and windy weather, the welding quality is difficult to guarantee, and welding defects are prone to occur, affecting the reliability of the connection. Moreover, welding is an irreversible operation. Once the welding is completed, if problems are found in the connection or the structure needs to be adjusted later, it is extremely difficult to modify it. It often requires complex processes such as cutting and grinding, which not only consumes a lot of manpower and material resources, but also may cause damage to the steel structure and reduce its mechanical properties. In addition, the specifications of steel beams and load-bearing columns for different projects are diverse, and the adjustment requirements for welding process parameters are strict, making it difficult to achieve standardized and rapid construction, resulting in low construction efficiency and extended construction period.
[0003] Bolt connection, as another common method, also has its limitations. When ordinary bolt connections are subjected to long-term vibration, alternating loads and other working conditions, the bolts are prone to loosening, which in turn causes the connection parts to loosen and deform, endangering the safety of the building structure. In order to solve the loosening problem, although there are some anti-loosening measures such as double nuts and spring washers, these traditional anti-loosening methods have limited effects in complex actual working conditions and it is difficult to completely eliminate the phenomenon of bolt loosening. Moreover, during the installation process, the positioning and tightening of the bolts require precise operations, which require a high level of skill and work attitude from the construction workers. Any carelessness may lead to uneven tightening force of the bolts, affecting the quality of the connection.
[0004] Furthermore, the traditional connection method is not very adaptable to steel beams and load-bearing columns of different specifications. Due to the lack of a flexible adjustment mechanism, it is often necessary to customize the connection scheme for components of specific specifications, which cannot achieve the universality of the connection components, increasing the types of building components and inventory management costs. When the building design is changed or the components are replaced, the construction may be hindered and the construction period may be delayed due to incompatible connection methods.
[0005] In addition, traditional connection methods face many difficulties in maintenance and repair. When problems occur in the connection parts, such as loose bolts and cracked welds, the repair process is complicated and requires the removal of a large number of surrounding structures or ancillary facilities before repair work can be carried out.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0026] Reference Figure 1 to Figure 12 , which is the first embodiment of the present invention, proposes an assembled building steel structure connection component, which is used for connecting a steel beam 1 and a load-bearing column 2 in a steel structure building. The steel beam 1 and the load-bearing column 2 are both I-beams, including a first mounting member 3, the first mounting member 3 is arranged on the load-bearing column 2, the first mounting member 3 has a cavity 302 and a slide groove 301, the slide groove 301 is connected to the cavity 302, one end of the load-bearing column 2 is located in the cavity 302, the load-bearing column 2 and the inner wall of the cavity 302 form an installation cavity 303, and the second mounting member 4 has a limiting portion 402 and a sliding portion 401, the sliding part 401 is slidably set in the slide groove 301, the limiting part 402 is movably set in the installation cavity 303, and the limiting part 402 abuts against or cancels the abutment with the cavity wall of the installation cavity 303 after moving. The connecting member 5 is set on the first installation member 3, and the connecting member 5 is used to connect the steel beam 1 with the second installation member 4. The fastening bolt 6 passes through the steel beam 1 and the connecting member 5 in sequence, and is threadedly connected with the fastening nut 7. The first anti-loosening member 8 is slidably set on the second installation member 4. After the first anti-loosening member 8 slides, it clamps the fastening bolt 6 to prevent the fastening bolt 6 from rotating.
[0027] In this embodiment, the cavity 302 provided in the first mounting member 3 is used to accommodate one end of the load-bearing column 2. This design enables the connecting member to be well combined with the load-bearing column 2, and an installation cavity 303 is formed between the inner wall of the cavity 302 and the load-bearing column 2, which provides a spatial basis for the installation and activity of other subsequent components. In actual prefabricated building construction, although the specifications of the load-bearing columns 2 of different projects are mostly I-beams, there may be certain differences in details such as size, and the inclusive design of the cavity 302 can adapt to these differences within a certain range, improve the adaptability of the connecting member to load-bearing columns 2 of different specifications, and facilitate application in a variety of building scenes. At the same time, the first mounting member 3 can be welded or bolted to the load-bearing column 2, with a simple structure and easy maintenance. The slide groove 301 connected to the installation cavity 303 provides a sliding track for the sliding portion 401 of the second mounting member 4, so that the second mounting member 4 can flexibly adjust the position according to the specific installation position and requirements of the steel beam 1. By sliding the sliding part 401 in the slide groove 301, the corresponding change in the position of the second mounting member 4 can be easily achieved, thereby creating favorable conditions for moving the steel beam 1 to an accurate installation position, enhancing the flexibility of the entire connecting component during the installation process, and reducing the installation difficulty caused by changes in on-site construction conditions.
[0028] The sliding part 401 of the second mounting member 4 cooperates with the slide groove 301 to slide, and the limiting part 402 is movable in the mounting cavity 303 and can abut against the cavity wall or cancel the abutment. This design makes the connection process between the steel beam 1 and the load-bearing column 2 more convenient and adjustable. When installing the steel beam 1, first move the second mounting member 4 along the slide groove 301 through the sliding part 401 to a position that does not affect the connection between the steel beam 1 and the connecting member 5, use the fastening bolt 6 and the fastening nut 7 to connect the steel beam 1 and the connecting member 5, and then operate the limiting part 402 to make it abut against the cavity wall of the mounting cavity 303, fix the position of the second mounting member 4, slide the first anti-loosening member 8, and perform secondary anti-loosening on the fastening bolt 8 to prevent the fastening bolt 8 from falling off.
[0029] The first anti-loosening member 8 is slidably disposed on the second mounting member 4 and can slide to clamp the fastening bolt 6. This design plays an important role in preventing the fastening bolt 6 from loosening or rotating due to factors such as vibration and alternating loads during long-term use. In the actual working conditions of steel structure buildings, such as when the building is exposed to wind and vibrations caused by the operation of machinery and equipment, the fastening bolt 6 is prone to loosening. Once loosened, it will affect the stability of the connection between the steel beam 1 and the load-bearing column 2, thereby endangering the safety of the building structure. The first anti-loosening member 8 can effectively limit the rotation of the fastening bolt 6 by clamping it, maintain the pre-tightening force of the fastening bolt 6, ensure that the connection part is always in a reliable tightening state, extend the service life of the connecting component, and enhance the reliability and durability of the entire steel structure building connection.
[0030] Since the installation method of the components of the entire connecting component is simple, when a component needs to be maintained or replaced, the operation is relatively convenient, and the maintenance process does not require large-scale disassembly of the entire connecting component, which greatly reduces the difficulty and workload of maintenance, shortens the maintenance time, reduces the impact on the normal use of steel structure buildings, and reduces the maintenance cost caused by component damage and indirect use costs such as building downtime losses caused by maintenance.
[0031] From the perspective of versatility, the design of the prefabricated steel structure connection component can adapt to various specifications of steel beams 1 and load-bearing columns 2. As long as they are in the form of I-beams, they have the potential for application in prefabricated steel structure construction projects of different scales and types. There is no need to customize unique connection components for each project, which reduces product research and development costs and production costs. At the same time, its good installation flexibility, connection stability and easy maintenance characteristics can reduce the number of repairs and cost expenditures caused by connection component problems during the entire service life of the building, improve the economy and cost-effectiveness of the building, enhance its competitiveness in the construction market, and have broad application prospects.
[0032] Furthermore, it also includes a second anti-loosening member 9, which is slidably set on the second mounting member 4. After the second anti-loosening member 9 slides, it clamps the fastening nut 7 to prevent the fastening nut 7 from rotating. The first anti-loosening member 8 and the second anti-loosening member 9 both have a clamping groove 905. The locking member 10 is slidably set on the steel beam 1. The locking member 10 has a clamping part 1001. After the locking member 10 slides, the clamping part 1001 slides into or out of the clamping groove 905.
[0033] In this embodiment, the second anti-loosening member 9 is slidably arranged on the second mounting member 4 and can clamp the fastening nut 7 after sliding, which provides additional anti-rotation protection for the fastening nut 7. In the actual use of steel structure buildings, relying solely on the threaded connection of the fastening bolt 6 itself and the anti-rotation effect of the first anti-loosening member 8 on the fastening bolt 6 may not be enough to completely resist the loosening risk caused by frequent vibrations, material expansion and contraction caused by temperature changes under long-term complex working conditions. The second anti-loosening member 9 clamps the fastening nut 7 and cooperates with the first anti-loosening member 8 to form a double anti-loosening mechanism for the bolt connection part. In a building environment such as an industrial plant where large equipment is often running and large vibrations are generated, this double anti-loosening measure can more effectively maintain the pre-tightening force between the fastening bolt 6 and the fastening nut 7, ensuring that the connection between the steel beam 1 and the load-bearing column 2 is always stable and reliable, greatly enhancing the stability and durability of the entire steel structure connection, and ensuring the safety of the building structure under long-term bearing of various loads.
[0034] At the same time, the sliding setting mode of the second anti-loosening member 9 is convenient for operation during installation, maintenance, etc. After tightening the fastening nut 7, the construction personnel can easily slide the second anti-loosening member 9 to a suitable position to clamp the fastening nut 7, and when it is necessary to disassemble or adjust the connection, it can also be convenient to release its clamping state, which will not cause too much obstruction to the overall installation and maintenance process, thereby improving the efficiency of construction and maintenance.
[0035] The locking member 10 slides into or out of the clamping groove 905 of the first anti-loosening member 8 and the second anti-loosening member 9 through its clamping portion 1001, further strengthening the entire anti-loosening system. When the clamping portion 1001 slides into the clamping groove 905, it is equivalent to "locking" the first anti-loosening member 8, the second anti-loosening member 9 and the steel beam 1 and other related components to a certain extent, making the relative positions between the components more fixed, avoiding the situation where the anti-loosening member loses its anti-loosening effect due to accidental displacement caused by external forces such as wind blowing, slight collisions, etc., and the locking effect of the locking member 10 can ensure that the anti-loosening function of the entire connecting member is continuously effective, ensuring the long-term reliability of the connection between the steel beam 1 and the load-bearing column 2, and reducing the structural safety hazards that may be caused by loose connections.
[0036] Moreover, the way in which the locking member 10 is slidably arranged on the steel beam 1 makes its operation relatively convenient. During the installation and maintenance process, the construction personnel can flexibly control the sliding of the clamping part 1001 according to the actual situation to achieve locking or unlocking of the entire connection structure, thereby improving the operability and adaptability of the entire steel structure connection component in practical applications.
[0037] When it is necessary to maintain the connection components, such as checking the anti-loosening effect, replacing worn anti-loosening parts, etc., this structural design facilitates targeted operations. Maintenance personnel can observe the state of the locking member 10 to determine whether it is necessary to further check the first anti-loosening member 8 and the second anti-loosening member 9. If a certain anti-loosening member needs to be replaced, it is only necessary to slide the locking member 10 to make the clamping part 1001 slide out of the clamping groove 905, and then the corresponding anti-loosening member can be easily disassembled and replaced without large-scale disassembly of the entire connection component, which greatly reduces the difficulty and workload of maintenance, shortens the maintenance time, reduces the impact on the normal use of the steel structure building, and improves the maintainability and availability of the equipment.
[0038] The second anti-loosening member 9, the locking member 10 and other connecting member components such as the first mounting member 3, the second mounting member 4, the fastening bolt 6, etc. cooperate with each other to jointly enhance the integrity of the entire steel structure connecting member. Through the close connection and mutual cooperation between the various components, an organic whole is formed, so that the connection between the steel beam 1 and the load-bearing column 2 is not only firm and reliable, but also can cooperate and resist external forces when facing various external forces such as earthquake loads, wind loads and other complex building stress conditions, avoiding structural damage caused by excessive stress on a certain component or loose connection, and ensuring the integrity and safety of the entire prefabricated steel structure building structure.
[0039] Furthermore, the second anti-loosening component 9 includes a first main body 901, which is arranged on the fastening nut 7 and has a first accommodating groove 903 and a limiting groove 906. The first accommodating groove 903 is used to accommodate the fastening nut 7, and the limiting groove 906 is connected to the first accommodating groove 903. The second main body 904 is slidably arranged on the second mounting component 4 and has a clamping groove 905, a limiting clamping portion 902 and a yielding groove 907. The limiting groove 906 is used to accommodate the limiting clamping portion 902. After the second main body 904 slides, one end of the fastening bolt 6 is located in the yielding groove 907, and the limiting clamping portion 902 is located in the limiting groove 906.
[0040] In this embodiment, the first receiving groove 903 provided in the first body 901 is used to accommodate the fastening nut 7. This design enables the fastening nut 7 to be well accommodated therein, and plays a role in positioning and restraining the fastening nut 7 in space. In the actual operation of the steel structure building, the fastening nut 7 is prone to loosening, displacement, etc. due to factors such as vibration and external force impact, and the first receiving groove 903 can limit its movement within a certain range, prevent it from rotating at will or leaving the original installation position, and ensure the initial state stability of the connection between the fastening nut 7 and the fastening bolt 6, thereby enhancing the stability of the connection between the steel beam 1 and the load-bearing column 2.
[0041] At the same time, the limiting groove 906 of the first body 901 cooperates with the limiting clamping part 902 of the second body 904 to further strengthen the limiting function of the entire anti-loosening structure. After the limiting clamping part 902 is inserted into the limiting groove 906, a relatively fixed connection relationship is formed between the first body 901 and the second body 904, preventing the first body 901 from unnecessary movement or rotation when disturbed by external forces, ensuring that it can always play an effective limiting and anti-loosening role for the fastening nut 7, even in a complex and changeable building stress environment such as frequent wind loads, slight deformation of the building structure, etc., it can maintain the stable state of the fastening nut 7, thereby improving the long-term reliability of the entire steel structure connection component.
[0042] The clamping groove 905 of the second body 904 provides a corresponding clamping position for the clamping part 1001 of the locking member 10. When the clamping part 1001 slides into the clamping groove 905, it realizes the coordinated anti-loosening with other components such as the first anti-loosening member 8, further "locks" the entire connection structure, effectively prevents the loosening and failure of each anti-loosening component due to unexpected circumstances, and enhances the overall anti-loosening effect. For example, in a building environment such as an industrial plant where there are many equipment running and generating vibrations, through this clamping fit, it is possible to better resist the impact of vibration on the anti-loosening structure of the fastening nut 7, ensure the stability of the connection between the steel beam 1 and the load-bearing column 2, and reduce the structural safety hazards that may be caused by loose connections.
[0043] The connection design of the limit groove 906 and the clearance groove 907 cleverly solves the problems of spatial adaptation and functional coordination between components. The limit groove 906 accommodates the limit clamping part 902 to ensure the accurate connection and relative fixation of the first body 901 and the second body 904, and the clearance groove 907 can accommodate one end of the fastening bolt 6 after the second body 904 slides, which not only avoids interference between the fastening bolt 6 and the second body 904, but also makes the structural layout of the entire second anti-loosening member 9 more reasonable and compact. While realizing the anti-loosening function, it does not affect the normal installation and operation of other components, and jointly ensures the stability and reliability of the entire steel structure connection component, and improves its adaptability under different working conditions.
[0044] During the installation of the steel structure connection components of the prefabricated building, this structural design of the second anti-loosening member 9 is convenient for construction workers to operate. First, align the first receiving groove 903 of the first main body 901 and put it on the tightened fastening nut 7, so that the limit groove 906 is in a suitable position, and then slide the second main body 904 along the second mounting member 4, so that the limit clamping part 902 is accurately inserted into the limit groove 906, and at the same time, one end of the fastening bolt 6 naturally enters the clearance groove 907. The entire installation process has clear steps and simple operation. It does not require complicated alignment and adjustment operations, and can quickly and efficiently complete the installation of the second anti-loosening member 9, which improves the overall efficiency of on-site construction and reduces the extension of construction time and increase in labor costs caused by cumbersome installation links.
[0045] Moreover, the clear installation sequence and coordination method between the various components require relatively low skills from the construction workers, making it easy to promote and apply in different construction teams, ensuring the consistency of the installation quality of steel structure connection components, which is beneficial to ensuring the construction quality of the entire prefabricated steel structure building.
[0046] When the second anti-loosening member 9 needs to be maintained or repaired, such as checking whether it is worn or damaged, or when a certain part needs to be replaced, its structural characteristics make the operation more convenient. If a problem is found in the first body 901 or the second body 904, the maintenance personnel only need to release the relevant connection relationship first, such as sliding the second body 904 in the opposite direction along the second mounting member 4 to make the limiting clamping part 902 disengage from the limiting groove 906, and then the corresponding parts can be easily disassembled for replacement or maintenance, without large-scale disassembly of the entire steel structure connection component, which greatly reduces the difficulty and workload of maintenance, shortens the maintenance time, reduces the impact on the normal use of the steel structure building, and improves the maintainability and availability of the equipment.
[0047] This structural design of the second anti-loosening member 9 enhances the versatility of the entire prefabricated building steel structure connection component to a certain extent. The first receiving groove 903 and the limiting groove 906 of the first main body 901 and the various groove structures of the second main body 904 can be adapted to fastening nuts 7, fastening bolts 6 and second mounting members 4 of different specifications by reasonably adjusting parameters such as size. In different prefabricated steel structure building projects, although the specifications of the selected steel beams 1, load-bearing columns 2 and related connection components may be different, as long as they are within a certain size range, the second anti-loosening member 9 can effectively play its anti-loosening function, without the need to customize unique anti-loosening members for each project, reducing product research and development costs and production costs, improving production efficiency, and also facilitating construction units to uniformly adopt this type of connection components in different projects for standardized construction and management.
[0048] Furthermore, the first anti-loosening member 8 has a clamping groove 801 , and the clamping groove 801 is used to accommodate and clamp the nut portion of the fastening bolt 6 .
[0049] In this embodiment, the first anti-loosening member 8 is provided with a clamping groove 801 for accommodating and clamping the nut portion of the fastening bolt 6. This design plays an effective anti-loosening role from the source for the fastening bolt 6. The clamping groove 801 clamps the nut portion tightly, which can limit the rotation of the fastening bolt 6, making it difficult for it to change the pre-tightening state due to external interference, ensuring the initial tightness of the connection between the steel beam 1 and the load-bearing column 2 through the fastening bolt 6, greatly enhancing the stability of the connection, and effectively avoiding structural safety hazards caused by loose bolts, such as displacement of the steel beam 1, gaps in the connection parts, etc., to ensure the structural integrity of the entire steel structure building.
[0050] Moreover, compared with some traditional methods that rely solely on thread friction to prevent loosening, this mechanical clamping method of clamping the nut part through the clamping slot 801 is more reliable and can withstand greater external force impact and vibration. Even under long-term and complex working conditions, it can continue to play an anti-loosening role, thereby extending the service life of the connecting components and providing a strong guarantee for the long-term safe use of steel structure buildings.
[0051] The clamping action of the clamping slot 801 of the first anti-loosening member 8 cooperates with other anti-loosening components such as the second anti-loosening member 9 to form a more rigorous anti-loosening system. When the second anti-loosening member 9 performs the corresponding anti-loosening operation on the fastening nut 7, the first anti-loosening member 8 clamps the nut part of the fastening bolt 6 through the clamping slot 801, restricting it from both ends of the bolt, making it difficult for the fastening bolt 6 to loosen in all directions. The anti-loosening performance of the entire steel structure connection component is further improved, and the durability and safety of the structure under complex stress conditions are enhanced.
[0052] During the installation of the prefabricated building steel structure connection components, the design of the slot 801 of the first anti-loosening member 8 is convenient for construction workers to operate. After passing the fastening bolt 6 through the steel beam 1 and the connection member 5 and preliminarily tightening the fastening nut 7, the construction workers only need to slide the first anti-loosening member 8 to a suitable position so that the slot 801 accurately clamps the nut of the fastening bolt 6. The operation is simple and direct, and does not require complicated tools or special installation skills. The installation of the first anti-loosening member 8 can be completed quickly, which improves the efficiency of on-site construction and reduces the situation where the overall construction progress is affected by the long time spent on installing the anti-loosening member.
[0053] The structure of the slot 801 of the first anti-loosening member 8 can be adapted to fastening bolts 6 of different specifications by adjusting parameters such as size to a certain extent. In different prefabricated steel structure construction projects, although the sizes of the fastening bolts 6 selected may be different, as long as the design of the slot 801 meets the corresponding specification requirements, the first anti-loosening member 8 can be applied to achieve the anti-loosening function, without the need to customize a unique anti-loosening member for each project, reducing product R&D costs and production costs, improving production efficiency, and also facilitating its widespread use in prefabricated steel structure buildings of different sizes and types, enhancing the versatility and market competitiveness of the entire steel structure connection component.
[0054] Further, the second mounting member 4 further has a guide rod 403 and an adjustment rod 404, the first mounting member 3 further has a first guide hole 304 and a second guide hole 305, the guide rod 403 passes through the first guide hole 304, the adjustment rod 404 passes through the second guide hole 305, the adjustment rod 404 is a threaded rod, and further includes: The adjusting nut 11 is threadedly disposed on the adjusting rod 404 and is located outside the mounting cavity 303 and abuts against the first mounting member 3. The adjusting nut 11 is configured to drive the limiting portion 402 to abut against or cancel the abutment with the cavity wall of the mounting cavity 303 when rotating.
[0055] In this embodiment, the guide rod 403 of the second mounting member 4 passes through the first guide hole 304 of the first mounting member 3. This design provides accurate guidance for the second mounting member 4 during installation and subsequent position adjustment. In the on-site construction of prefabricated building steel structures, ensuring that each component is accurately installed in place is crucial to the stability and safety of the entire structure. The cooperation between the guide rod 403 and the first guide hole 304 is like installing a "track" for the second mounting member 4, so that it can only slide in a predetermined direction, avoiding offset and dislocation during the installation process, and improving the accuracy and efficiency of the installation.
[0056] The adjusting rod 404 passes through the second guide hole 305 and the adjusting nut 11 is threadedly arranged on the adjusting rod 404 and abuts against the first mounting member 3. By rotating the adjusting nut 11, the limiting portion 402 can be driven to abut against or cancel the abutment with the wall of the mounting cavity 303, which provides a convenient and precise adjustment method for fixing the position of the second mounting member 4.
[0057] Compared with some traditional fixing methods such as simple bolt fixing and welding, this adjustment method is more flexible. It can achieve position adjustment without large-scale disassembly or reinstallation of installed components. It not only improves construction efficiency, but also reduces the risk of damage to components caused by adjusting the installation position. At the same time, it is also convenient for timely maintenance and adjustment according to structural deformation, load changes, etc. during the subsequent use of the building, ensuring the long-term applicability and reliability of steel structure connection components.
[0058] The guide rod 403, the adjustment rod 404, the adjustment nut 11 and other components together with the first mounting member 3, the second mounting member 4 and the like form an integral structure that is subjected to coordinated force. When bearing load, the various components cooperate with each other to reasonably transfer the force transmitted from the steel beam 1 to the load-bearing column 2 through the second mounting member 4, the adjustment rod 404 and the like. At the same time, the abutment between the limit portion 402 and the wall of the mounting cavity 303 and the positioning function of the guide rod 403 ensure the stability of the force transmission path. This coordinated force-bearing method avoids damage caused by excessive force on a single component, enhances the integrity and durability of the entire steel structure connection component, enables the entire prefabricated steel structure building to better maintain the integrity of the structure during long-term use, reduces the cost expenditure of maintenance, reinforcement and the like caused by unreasonable structural force, and improves the economy and service life of the building.
[0059] Since the adjusting nut 11 is located outside the mounting cavity 303 and is easily accessible, when it is necessary to readjust the position of the second mounting member 4 or to perform maintenance on related components such as the adjusting rod 404 and the limiting portion 402, the operation is relatively convenient.
[0060] In summary, the related designs such as the guide rod 403, the adjustment rod 404 and the adjustment nut 11 of the second mounting part 4 in the prefabricated building steel structure connection component further optimize the performance of the entire steel structure connection component through the advantages shown in many aspects such as installation and adjustment convenience, structural stability, maintenance convenience and cost control, so that it can better meet the requirements of prefabricated steel structure buildings for the stable connection between the steel beam 1 and the load-bearing column 2 under complex construction conditions and long-term use, which is of great significance in practical applications.
[0061] Further, the steel beam 1 has a mounting hole 101 and a clamping surface 102, the clamping surface 102 is located on one side of the mounting hole 101, and the clamping portion 1001 penetrates and is slidably disposed in the mounting hole 101, and further includes: The swinging member 12 is swingably disposed on the clamping portion 1001. After the swinging member 12 swings, it abuts against or cancels the abutment with the clamping surface 102. The elastic member 13 has one end acting on the clamping portion 1001 and the other end acting on the swinging member 12 to provide a force for clamping the swinging member 12 with the clamping surface 102 .
[0062] In this embodiment, the swinging member 12 can abut against the clamping surface 102 after swinging. This design adds a reliable and stable defense line to the connection between the steel beam 1 and other components such as related structures connected to the load-bearing column through the connecting member. One end of the elastic member 13 acts on the clamping portion 1001, and the other end acts on the swinging member 12, continuously providing force for the clamping of the swinging member 12 and the clamping surface 102, which makes the stability of the connection continuous. During long-term use, even if there are some slight dimensional changes in the connection part due to factors such as temperature changes and slight structural deformation, the elastic member 13 can automatically adjust the abutment force between the swinging member 12 and the clamping surface 102 through its own elastic expansion and contraction characteristics, always maintain a good clamping state, maintain the reliability of the connection, ensure that the connection can function stably under different working conditions, extend the service life of the connecting component, and further enhance the durability of the entire steel structure building connection.
[0063] During the installation of the prefabricated building steel structure connection components, the cooperation of the swinging member 12, the elastic member 13 and the related structures makes the operation relatively simple. After the construction personnel pass the clamping part 1001 of the steel beam 1 through the installation hole 101, the swinging member 12 can naturally form a clamping connection with the clamping surface 102 by relying on the elastic force of the elastic member 13. Without the need for complicated additional fixing operations or the use of special tools, the connection work of this part of the steel beam 1 can be completed quickly, which improves the efficiency of on-site construction and reduces the extension of construction time and increase in labor costs caused by cumbersome installation links.
[0064] When the steel beam 1 needs to be disassembled, such as in the case of building renovation, maintenance or component replacement, the structure is also easy to operate. The maintenance personnel only need to overcome the elastic force of the elastic member 13 and push the swing member 12 away from the state of abutting against the clamping surface 102 to release the clamping relationship, and then smoothly pull the steel beam 1 out from the corresponding connection position without large-scale disassembly of the entire connection component, which greatly reduces the difficulty and workload of maintenance, shortens the maintenance time, reduces the impact on the normal use of the steel structure building, and improves the maintainability and availability of the equipment.
[0065] This structural design that realizes the clamping by the swinging member 12, the elastic member 13 and the clamping surface 102 can, to a certain extent, adapt to steel beams 1 of different specifications and other components connected thereto by adjusting parameters such as the size of related components and the elastic coefficient of the elastic member 13.
[0066] In summary, the structures such as the swinging member 12, the elastic member 13 and the matching clamping surface 102 arranged on the steel beam 1, through the advantages shown in many aspects such as connection stability, installation and disassembly convenience, structural adaptability and versatility, further optimize the performance of the connection components of the prefabricated building steel structure, so that it can better meet the requirements of the steel structure building for the stable connection of the steel beam 1 and other components under complex working conditions and different specifications, which is of great significance in practical applications.
[0067] Furthermore, the first mounting member 3 also has a connecting cavity 306 . The connecting cavity 306 and the receiving cavity 302 are respectively located on two sides of the first mounting member 3 . The connecting cavity 306 is used to accommodate another load-bearing column 2 .
[0068] In this embodiment, the connection cavity 306 provided in the first mounting member 3 is used to accommodate another load-bearing column 2. This design greatly expands the application scenarios and connection functions of the connection component. In prefabricated steel structure buildings, it is often necessary to connect or intersect multiple load-bearing columns 2. For example, at the node of the building, the load-bearing columns 2 in different directions need to bear force together and work together to support the entire building structure. Through the connection cavity 306, another load-bearing column 2 can be easily incorporated into the connection system of the existing load-bearing column 2 and the steel beam 1 to form a more complex and stable structural framework, meet the diverse architectural design needs, and make the building structure more reasonable and efficient in spatial layout and force transmission.
[0069] The connection cavity 306 and the receiving cavity 302 are respectively located on both sides of the first mounting member 3. This layout makes the connection of the load-bearing column 2 more flexible and diverse. Construction personnel can select different load-bearing columns 2 to connect to the first mounting member 3 from both sides according to the specific structural design of the building and the actual situation on site, ensuring that the vertically intersecting load-bearing columns 2 can be firmly connected by adjusting the connection cavity 306 and the receiving cavity 302. This has obvious advantages in dealing with complex building shapes, irregular structural layouts, etc., and can better adapt to the personalized needs of various prefabricated steel structure construction projects, reduce the connection problems caused by special structures, and improve construction efficiency and structural rationality.
[0070] The existence of the connection cavity 306 enables the first mounting member 3 to form a more compact and coordinated overall structure with the two load-bearing columns 2 and the steel beam 1. The various components interact and restrict each other, and can work together when bearing loads, thus avoiding the situation where the entire structure is unbalanced due to the deformation or displacement of a single component.
[0071] Furthermore, the connecting member 5 has an anti-rotation groove 501, and the anti-rotation groove 501 is used to accommodate the nut portion.
[0072] In this embodiment, the anti-rotation groove 501 provided in the connector 5 is used to accommodate the nut portion of the fastening bolt 6. This design fundamentally enhances the stability of the connection. In the actual use of the steel structure building, various external forces such as the wind load on the building, the vibration generated by the operation of the equipment, and the structural expansion and contraction caused by temperature changes can easily cause the fastening bolt 6 to rotate, thereby causing the connection to loosen. The anti-rotation groove 501 can accurately accommodate and limit the rotation of the nut portion, so that the fastening bolt 6 can maintain a stable state after installation, effectively preventing it from changing the pre-tightening degree due to external interference, ensuring that the connection between the steel beam 1 and the load-bearing column 2 through the connector 5 is always firm and reliable, greatly reducing the risk of structural safety hazards caused by bolt loosening, such as displacement of the steel beam 1, gaps in the connection part, etc., to ensure the integrity of the entire steel structure building structure. When installing the fastening bolt 6, the anti-rotation groove 501 can ensure the position of the nut portion of the fastening bolt 6 relative to the connector 5, and ensure the cooperation between the nut portion and the slot 801.
[0073] Moreover, compared with the conventional method of simply relying on thread friction to prevent the bolt from rotating, the mechanical limiting method of the anti-rotation groove 501 is more direct and reliable, and can withstand greater external force impact and vibration. Even under long-term and complex working conditions, it can continue to play an anti-rotation role, thereby extending the service life of the connecting components and providing a strong guarantee for the long-term safe use of steel structure buildings.
[0074] Furthermore, the sliding portion 401 has a lifting portion 405 , which is located at the lower side of the sliding portion 401 , and a gap 406 is provided between the steel beam 1 and the lifting portion 405 .
[0075] In this embodiment, the lifting part 405 can hold up the steel beam 1 when the steel beam 1 falls, so as to prevent the steel beam 1 from falling instantly, thereby ensuring the safety of personnel and leaving time for emergency repairs after damage to the steel structure building. The design of the gap 406 ensures that the sliding part 401 can slide smoothly.
[0076] Furthermore, a locking member 10 has two clamping parts 1001, and the clamping parts 1001 have threaded connection holes 1002. The threaded connection holes 1002 are arranged in a plurality, and the threaded connection holes 1002 on the two clamping parts 1001 correspond to each other one by one. It also includes: connecting bolts 14, and there are a plurality of connecting bolts 14, and each connecting bolt 14 is threadedly connected to a group of threaded connection holes 1002 at corresponding positions.
[0077] In this embodiment, a locking member 10 is provided with two clamping parts 1001, and is threadedly connected with corresponding threaded connection holes 1002 through a plurality of connecting bolts 14. This structural design greatly enhances the stability of the connection. In a steel structure building, the connection between the steel beam 1 and the load-bearing column 2 needs to withstand external forces from the deadweight of the building, personnel activities, wind loads, earthquake loads and other aspects. A stable connection is essential to ensure the safety of the entire building structure. The two clamping parts 1001 clamp the relevant components such as anti-loosening parts from different positions, and then with the help of the tightening effect of the connecting bolts 14, the locking member 10 can more firmly connect the components together to form a tight whole, effectively avoiding the occurrence of loose connection and separation due to external force impact or long-term vibration, ensuring the reliability of the connection structure between the steel beam 1 and the load-bearing column 2 under complex stress environments, and maintaining the integrity of the entire steel structure building structure system.
[0078] A plurality of arranged threaded connection holes 1002 are arranged on the clamping part 1001, and correspond to each other one by one, so that the connection bolts 14 can be evenly distributed on the clamping part 1001, which is conducive to dispersing the external force more evenly. When the building structure is subjected to load, the force will be transmitted and dispersed through each connection bolt 14. The layout of the plurality of threaded connection holes 1002 avoids the stress concentration on a few connection points, reduces the load borne by a single connection bolt 14, reduces the risk of damage and loosening of the connection bolt 14 due to excessive local force, prolongs the service life of the connection bolt 14 and the entire connection component, further enhances the durability and bearing capacity of the entire steel structure connection component, and ensures the stability of the steel structure building during long-term use.
[0079] During the installation of the prefabricated building steel structure connection components, the design of the locking member 10 with the double clamping parts 1001, the threaded connection holes 1002 and the connection bolts 14 is convenient for construction workers to operate. Construction workers only need to align the two clamping parts 1001 with the positions of the components to be clamped, and then pass the connection bolts 14 through the corresponding threaded connection holes 1002 in turn and tighten them. The operation steps are relatively clear and simple, and no complicated installation skills or special tools are required. The installation of the locking member 10 can be completed quickly, which improves the efficiency of on-site construction and reduces the extension of construction time and increase in labor costs caused by cumbersome installation links.
