[0003] At present, there are various connection methods between modules of existing modular steel structure buildings, including but not limited to applying prestress in columns, using cast steel parts as a whole for beam-column connectors, column-to-column connectors with special structures, column base welding, mortise and tenon connections, etc.; although these methods meet the requirements of structural connection to a certain extent, they generally have the disadvantages of complex construction, high project cost, and the need for on-site welding operations. More importantly, due to the special structure of modular buildings, relative sliding is likely to occur between modules under lateral actions, and it is difficult for upper and lower module beams to cooperate in bearing force, which not only affects the normal work and life of people in the building, but also may cause the overall instability of the structure. Especially in the context that all regions in China are seismic fortification areas, the seismic performance of the module connection structure has become an important factor affecting the development of modular buildings.

Detailed implementation manners

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the description of this application and the above drawings are used to distinguish different objects and are not used to describe a specific order.

[0031] References to "embodiments" in this specification mean that particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] An embodiment of the present invention provides a modular steel structure connection device, as Figure 1-10 shown. The modular steel structure connection device includes: a connection shell 2 assembled at the bottom of the upper modular steel column 1, the connection shell 2 being used to connect and assemble the lower modular steel column 3; a docking block 4 disposed within the connection shell 2 and capable of being separated, the bottom of the docking block 4 being fixedly connected to the top of the lower modular steel column 3; a positioning socket 5 opened on the docking block 4 for positioning, a separable plug block 6 being disposed within the socket 5, one end of the plug block 6 being fixedly connected to the inner wall of the connection shell 2; a locking mechanism disposed on the plug block 6 for positioning the docking block 4; and a reset mechanism disposed on the plug block 6 for resetting the locking mechanism.

[0033] It should be noted that most of the existing connection methods between modular steel structure building modules require highly professional construction skills and complex operation processes. For example, applying prestress in columns requires precise control of the magnitude and distribution of prestress to ensure the strength and stability of the connection, which usually involves complex calculations and construction processes. Another example is that the overall beam-column connection area uses cast steel parts. Although it can improve the strength and durability of the connection, the production cycle of cast steel parts is long, the cost is high, and on-site installation requires high-precision positioning and fixing. These complex construction processes and on-site operations not only increase the construction difficulty and time cost, but also pose higher requirements for the skills and experience of construction workers. The high project cost is one of the common problems of the existing connection methods. Using special materials and complex processes often means higher material costs and processing fees. For example, the production and processing costs of cast steel parts are significantly higher than those of ordinary steel, and column connectors with special structures usually need to be customized, which will increase the project cost. In addition, the complex construction process will also lead to an increase in labor costs and time costs, further driving up the total cost. The high project cost not only increases the burden on the construction party, but also limits the application of modular steel structure buildings in a wider range of fields. The special structure of modular buildings makes it prone to problems when subjected to lateral loads. Since the connection between modules mostly relies on the contact and fixation at the joints, when subjected to horizontal forces, relative slip or angular displacement is likely to occur between modules. This kind of slip or displacement will not only reduce the overall stiffness and stability of the structure, but also exacerbate the dynamic response of the structure, resulting in greater damage. Especially during natural disasters such as earthquakes, the sudden increase in lateral loads may cause the overall instability or even collapse of the structure, causing heavy losses to personnel and property. Another key problem of modular buildings is the cooperative force-bearing between the upper and lower module beams. Due to the gaps between modules and the flexibility of connection nodes, it is difficult for the upper and lower module beams to form an effective overall action when bearing loads. This leads to a complex and unpredictable internal force distribution in the structure under the combined action of vertical and horizontal loads. At the same time, due to the insufficient cooperative action between the upper and lower module beams, stress concentration and damage may also occur in local areas of the structure. In summary, a modular steel structure connection device is needed to solve the above problems.

[0034] In this embodiment, the connection housing 2 is assembled to the bottom of the upper module steel column 1, which is the basis for the installation of the connection device, ensuring that the connection housing 2 can stably support and connect subsequent components. The docking block 4 is snapped into the connection housing 2. After the docking block 4 is snapped in, the insertion block 6 will be inserted into the insertion hole 5 on the docking block 4, and the locking mechanism on the insertion block 6 is used to position and lock the docking block 4. This step realizes the precise docking and stable connection between the upper module steel column 1 and the lower module steel column 3, preventing relative slip or angular displacement; when it is necessary to disassemble or adjust the connection device, the locking mechanism is reset through the reset mechanism, and then the docking block 4 and the insertion block 6 are separated to complete the disassembly, and the operation is relatively convenient. Through the assembly of the connection housing 2 and the bottom of the upper module steel column 1, the fixed connection between the docking block 4 and the top of the lower module steel column 3, and the insertion positioning of the insertion hole 5 and the insertion block 6, the construction process is simplified, without complex prestress control or high-precision positioning, reducing the difficulty of on-site construction and the dependence on the skills of construction workers; after using this device, there is no need to use costly cast steel parts or customized connectors, reducing the use of special materials and complex processes, thereby reducing material costs and processing fees. At the same time, the simplified operation process reduces labor costs and time costs, effectively controlling the project cost; the locking mechanism on the insertion block 6 ensures the stable connection between the modules. Even when subjected to lateral loads, such as natural disasters like earthquakes, it can effectively prevent relative slip or angular displacement between the modules, improving the overall stiffness and stability of the structure, enhancing the seismic performance, and reducing the risk of structural damage; the setting of the reset mechanism facilitates the rapid reset of the locking mechanism and is convenient for the disassembly of the upper module steel column 1 and the lower module steel column 3.

[0035] In a further preferred embodiment of the present invention, the locking mechanism includes: a slide bar 7 fixed on the insertion block 6, and a sleeve block 8 that can move up and down is sleeved on the slide bar 7; a connecting plate 9 assembled on the sleeve block 8, a positioning block 10 is fixed on the top of the connecting plate 9, and the positioning block 10 is used for inserting and locking the docking block 4; a first spring 11 arranged on the insertion block 6, and the top of the first spring 11 is fixedly connected to the bottom of the connecting plate 9.

[0036] In this embodiment, the sliding rod 7 serves as the guiding track for the up-and-down movement of the sleeve block 8, ensuring that the sleeve block 8 does not deviate from the predetermined path during movement, thus ensuring the overall performance of the locking mechanism. The movement of the sleeve block 8 is triggered by an external operation (such as pressing or lifting), and the locking or unlocking function is achieved by changing its position on the sliding rod 7; the connecting plate 9 serves as an intermediate transmission member to convert the movement of the sleeve block 8 into a change in the position of the positioning block 10; when the docking block 4 is inserted into the connection housing 2, it will squeeze the positioning block 10, and the sleeve block 8 moves downward to compress the first spring 11. After the docking block 4 completes the insertion action, the positioning block 10 is inserted into the corresponding insertion slot of the docking block 4, and the first spring 11 rebounds to achieve locking. Conversely, when the positioning block 10 disengages from the insertion slot, the unlocking function is achieved; through the precise cooperation of the sliding rod 7, the sleeve block 8, the connecting plate 9, and the positioning block 10, the stable locking of the docking block 4 is realized. The process of the positioning block 10 inserted into the docking block 4 is stable and reliable, effectively preventing relative sliding or angular displacement between the modules; the design of the locking mechanism is simple and clear, making it easy for construction personnel to operate and maintain. The locking or unlocking function can be achieved only by pressing or lifting the sleeve block 8, without the need for complex tools or skills.

[0037] In a further preferred embodiment of the present invention, the reset mechanism includes: a connecting rod 12 fixedly installed on the connecting plate 9 for regulating its up-and-down movement, and both ends of the connecting rod 12 penetrate through the insertion block 6; a sliding plate 14 slidably installed on the insertion block 6, a connecting frame 13 is fixed to the bottom end of the sliding plate 14, and one end of the connecting frame 13 is fixedly connected to the bottom end of the connecting rod 12; a second spring 15 sleeved on the sliding plate 14, the bottom of the second spring 15 is in contact with the top of the insertion block 6; an assembly plate 16 slidably sleeved on the sliding plate 14, the bottom of the assembly plate 16 is fixedly connected to the top end of the connecting rod 12; a first hand piece 17 fixed on the sliding plate 14 for pressing.

[0038] In this embodiment, the design of the reset mechanism ingeniously combines mechanical principles to achieve the automatic reset function of the locking mechanism. When the locking mechanism is in the locked state, the connecting plate 9 and the positioning block 10 firmly lock related components (such as connectors between modules) together. At this time, the sliding plate 14 is located at a certain position within the plug-in block 6, and the second spring 15 provides an upward supporting force to maintain the reset state. The assembly plate 16 is stably sleeved on the sliding plate 14 and is connected to the connecting plate 9 through the connecting rod 12. When the user needs to unlock, by pressing the first hand piece 17, the first hand piece 17 drives the assembly plate 16 to slide downward along the sliding plate 14. During this process, the second spring 15 is compressed, and at the same time, the connecting rod 12 descends accordingly, thereby driving the connecting plate 9 and the positioning block 10 to move downward. As the positioning block 10 disengages from the plug-in slot, the locking mechanism is unlocked, and the connection between the modules is released. Once the pressed first hand piece 17 is released, the restoring force of the second spring 15 immediately starts to act, pushing the sliding plate 14 to slide upward. The upward movement of the sliding plate 14 is transmitted to the connecting plate 9 through the connecting frame 13 and the connecting rod 12, thereby driving the positioning block 10 back to its initial position. In this way, the locking mechanism completes the automatic reset process and is ready for the next locking operation. The automatic reset function reduces the need for manual intervention, enabling construction personnel to complete the connection and unlocking operations between modules faster, thus improving the overall construction efficiency.

[0039] In a further preferred embodiment of the present invention, a positioning mechanism for positioning the sliding plate 14 is provided on the plug-in block 6. The positioning mechanism includes: a mounting block 18 fixed to the bottom of the plug-in block 6, a retractable pin rod 19 slidably mounted on the mounting block 18; a first pulling ring 20 fixed to one end of the pin rod 19 for pulling; a third spring 21 sleeved on the pin rod 19 and capable of contracting, one end of the third spring 21 being fixedly connected to the mounting block 18; and a limiting block 22 assembled at the other end of the pin rod 19 for positioning the sliding plate 14.

[0040] In this embodiment, the positioning mechanism added to the plug-in block 6 provides a more precise positioning function for the sliding plate 14, thereby enhancing the stability and reliability of the reset mechanism. The mounting block 18 is fixed to the bottom of the plug-in block 6 as the mounting base of the positioning mechanism. The pin rod 19 is slidably mounted on the mounting block 18 and is designed to be pullable. The pulling action of the pin rod 19 is the key for the positioning mechanism to achieve the positioning function. The first pull ring 20 is fixed to one end of the pin rod 19 for the user to pull the pin rod 19. When the reset mechanism is in a non-working state or ready for reset, the limit block 22 is usually located at the end of the pin rod 19 and is under the thrust of the third spring 21 to maintain a certain tension. At this time, the limit block 22 does not contact the positioning groove 23 on the sliding plate 14. When it is necessary to reset the positioning block 10, the user first presses the sliding plate 14 to slide downward. As the sliding plate 14 slides down, the positioning groove 23 on it will gradually approach the limit block 22. When the positioning groove 23 is aligned with the limit block 22, under the elastic force of the third spring 21, the limit block 22 will snap into the positioning groove 23. At this time, the sliding plate 14 is accurately positioned at a specific position on the plug-in block 6. Once the sliding plate 14 is positioned, the positioning block 10 will correspondingly retract into the assembly groove on the docking block 4. This positioning prevents the first spring 11 and the second spring 15 from rebounding. When it is necessary to separate the docking block 4 from the connection shell 2, since the sliding plate 14 has been accurately positioned and fixed, the user can more easily control the separation process. After the docking block 4 is separated from the connection shell 2, by simply releasing the operation and pulling the first pull ring 20 to slide the pin rod 19, the limit block 22 is disengaged from the positioning groove 23, thereby unlocking the sliding plate 14, and the positioning block 10 will also be reset accordingly.

[0041] In a further preferred embodiment of the present invention, a positioning groove 23 is formed on the sliding plate 14, the positioning groove 23 is adapted to the limit block 22, and a guide rod 24 is fixedly installed on the inner wall of the connection shell 2. The guide rod 24 penetrates through the plug-in block 6 for limiting and guiding it.

[0042] In this embodiment, a positioning groove 23 is formed on the sliding plate 14, and the groove is adapted to the limit block 22. This design enables the limit block 22 to accurately snap into the positioning groove 23, thereby achieving precise positioning of the sliding plate 14. A guide rod 24 is fixedly installed on the inner wall of the connection shell 2. The guide rod 24 penetrates through the plug-in block 6 and is used for limiting and guiding it. The presence of the guide rod 24 restricts the movement trajectory of the plug-in block 6 in the connection shell 2, preventing the plug-in block 6 from shifting during the reset or separation process. At the same time, the guide rod 24 also provides stable support for the plug-in block 6, enhancing the stability of the connection.

[0043] In a further preferred embodiment of the present invention, a detachable side cover 25 is provided on the side of the connection shell 2. A groove block 26 for limiting the guide rod 24 is fixedly installed on the inner wall of the side cover 25. A separable insertion rod 31 is provided on the groove block 26, and the bottom end of the insertion rod 31 is clamped with the guide rod 24.

[0044] In this embodiment, the sealed side cover 25 is provided on the side of the connection shell 2. It is not only detachable for easy inspection of internal components, but also has a sealing performance to prevent external factors such as dust and moisture from invading the inside of the connection shell 2 and protecting the internal components from damage. The groove block 26 is fixedly installed on the inner wall of the sealed side cover 25 for limiting the guide rod 24. The design of the groove block 26 ensures the stable position of the guide rod 24 inside the connection shell 2 and prevents it from shifting or shaking. The insertion rod 31 is provided on the groove block 26 and is a separable component. The bottom end of the insertion rod 31 is clamped with the guide rod 24. The guide rod 24 can be fixed or released through a simple plugging and unplugging action, further improving the stability of the docking block 4 and preventing its displacement for safety insurance.

[0045] In a further preferred embodiment of the present invention, an adjusting mechanism for regulating the lifting of the guide rod 24 is provided on the side cover 25. The adjusting mechanism includes: an assembly rod 27 fixed on the side cover 25, and a fourth spring 28 is sleeved on the assembly rod 27; a sleeve plate 29 that is sleeved on the assembly rod 27 and can slide up and down, and the sleeve plate 29 is fixedly connected to the insertion rod 31; a second hand piece 30 fixed on the sleeve plate 29, and one end of the second hand piece 30 extends out of the side cover 25.

[0046] In this embodiment, the assembly rod 27 is firmly fixed to the side cover 25 and serves as the main support structure of the entire adjustment mechanism. It not only provides a stable track for the up-and-down sliding of the sleeve plate 29 but also ensures the firm installation of the adjustment mechanism on the side cover 25; the stability of the assembly rod 27 guarantees the smoothness and reliability of the sleeve plate 29 during the sliding process. Even when adjusted frequently or subjected to external forces, the sleeve plate 29 can slide stably along the track of the assembly rod 27, avoiding shaking or deviation. Before separating the docking block 4, the user can pinch the two second handpieces 30 with fingers and move them closer to each other. This action indirectly acts on the sleeve plate 29 through the fixed connection between the sleeve plate 29 and the second handpieces 30. As the two second handpieces 30 move closer to each other, the distance between the two sleeve plates 29 also becomes smaller. This change occurs along the axial direction of the assembly rod 27, ensuring the smoothness and directionality of the sliding. The decrease in the distance between the sleeve plates 29 causes the sleeve plates 29 to generate a compressive force on the fourth spring 28. The fourth spring 28, as an elastic element, plays a buffering and resetting role in this process. When the external force (i.e., the force exerted by the user to pinch the second handpieces 30) disappears, the fourth spring 28 releases the stored elastic potential energy and pushes the sleeve plate 29 back to its original position. As the sleeve plate 29 slides and the fourth spring 28 is compressed, the bottom end of the insertion rod 31 gradually disengages from the slot on the guide rod 24 and the groove block 26. This action unlocks the guide rod 24 and the insertion rod 31, facilitating subsequent disassembly operations. After the insertion rod 31 is completely disengaged from the guide rod 24 and the groove block 26, the user can easily remove the side cover 25 from the connection shell 2 for subsequent disassembly operations.

[0047] In a further preferred embodiment of the present invention, a sealing cover 32 for sealing and capable of covering the second handpiece 30 is provided on the side cover 25. A second pull ring 34 for pulling is provided on the sealing cover 32. Magnet blocks 33 that can adsorb each other are inlaid on the contact surface between the sealing cover 32 and the side cover 25.

[0048] In this embodiment, the design of the side cover 25 has been further optimized. In particular, by adding a sealing cover 32, which is arranged on the side cover 25. Its main function is to seal the assembly port on the side cover 25 and cover the second handle piece 30. This design effectively prevents external factors such as dust and moisture from invading the interior of the device through the gap between the second handle piece 30 and the assembly port on the side cover 25, further improving the sealing performance and protection level of the device. To facilitate the user to open the sealing cover 32, a second pull ring 34 is provided on the sealing cover 32. The user only needs to simply pull the second pull ring 34 to easily separate the sealing cover 32 from the side cover 25, thus exposing the second handle piece 30 below for subsequent operations. On the contact surface between the sealing cover 32 and the side cover 25, magnet blocks 33 that can adsorb each other are inlaid. This design utilizes the adsorption force of the magnets to maintain the stability of the sealing cover 32 in the closed state. When the sealing cover 32 is correctly installed on the side cover 25, the magnet blocks 33 will attract each other and fit tightly, preventing the sealing cover 32 from accidentally opening or loosening.

[0049] In a further preferred embodiment of the present invention, an installation groove for inserting the docking block 4 is provided on the connection shell 2. A detachable baffle 35 is arranged on the connection shell 2. A plurality of mounting pieces 36 are symmetrically and fixedly installed on the baffle 35. Screws for positioning are provided on the mounting pieces 36, and the screws are threadedly connected to the connection shell 2.

[0050] In this embodiment, an installation groove for inserting the docking block 4 is provided on the connection shell 2. This design enables the docking block 4 to be accurately positioned and fixed on the connection shell 2, ensuring the overall stability and reliability of the reset mechanism. The sealing baffle 35 is installed on the connection shell 2 to hermetically cover the operation groove on the connection shell 2. A plurality of mounting pieces 36 are symmetrically and fixedly installed on the baffle 35. Screws for positioning are provided on the mounting pieces 36. These screws match the threaded holes on the connection shell 2, and the baffle 35 and the connection shell 2 are tightly fixed together through threaded connection.

[0051] In a further preferred embodiment of the present invention, a sloped guiding groove and a plugging groove are provided on the docking block 4, and both the guiding groove and the plugging groove are adapted to the positioning block 10.

[0052] In this embodiment, the guiding groove provided on the docking block 4 not only has the function of guiding the insertion of the positioning block 10, but also the groove wall is designed as a slope. This slope design enables the positioning block 10 to gradually adapt to the change in groove width during the insertion process, thus making it easier to achieve smooth transition and accurate positioning. The introduction of the sloped guiding groove reduces the insertion resistance and improves the convenience of installation. The plugging groove connected to the guiding groove and the tight fit between the plugging groove and the positioning block 10 achieve the stable positioning of the docking block 4.

[0053] To further improve the usage effect of this device, in addition to the above solution, this solution also has the following embodiments:

[0054] In another embodiment of the present invention, an oil injection mechanism for introducing lubricating oil to infiltrate the internal components is provided on the connection shell 2. The oil injection mechanism includes: a conduit 37 fixedly connected to the connection shell 2 for injecting lubricating oil, a valve 38 provided at the oil inlet end of the conduit 37, a funnel 39 assembled at the liquid inlet end of the valve 38, and an oil bottle 40 for containing lubricating oil provided on the funnel 39.

[0055] In this embodiment, in order to maintain the smooth operation of the internal components of the connection shell 2 and delay the rust and damage caused by friction, oxidation, etc., an oil injection mechanism is specially added. This design aims to reduce the friction between internal components through regular lubrication, thereby protecting the components from wear and extending the service life of the entire device; the conduit 37 serves as a channel for the lubricating oil to enter the internal components, and the conduit 37 is fixedly connected to the connection shell 2. Its design ensures that the lubricating oil can be accurately delivered to the parts that need to be lubricated; the valve 38 is provided at the oil inlet end of the conduit 37 to control the injection amount and timing of the lubricating oil. By switching the valve 38, the user can easily control the lubrication process and avoid the situation of excessive or insufficient lubricating oil; the funnel 39 is assembled at the liquid inlet end of the valve 38, and its shape design helps to guide the smooth flow of the lubricating oil. The presence of the funnel 39 reduces the risk of splashing or overflowing of the lubricating oil, making the oil injection process safer and more efficient; the oil bottle 40 is used as a storage container for the lubricating oil, and the oil bottle 40 is provided on the funnel 39. The user can pour the lubricating oil into the oil bottle 40 and then inject it into the connection shell 2 through the funnel 39 and the conduit 37. The design of the oil bottle 40 ensures the sufficient supply and convenient replacement of the lubricating oil. The lubricating oil injected through the oil injection mechanism can fully infiltrate the internal components such as the docking block 4, the plug-in block 6, the sliding rod 7, the sleeve block 8, the connecting plate 9, the positioning block 10, the first spring 11, the connecting rod 12, the connecting frame 13, the sliding plate 14, and the second spring 15. Under the action of the lubricating oil, the friction coefficients of these components are significantly reduced and the operation is smoother; the lubricating oil not only has the function of reducing friction, but also can form a protective film on the surface of the components to isolate air and moisture, thereby delaying the rust and damage of the components. This is of great significance for improving the overall durability and reliability of the device.

[0056] In summary, compared with the related technologies, the modular steel structure connection device proposed by the present invention simplifies the construction process through the insertion and positioning of the jack 5 and the insertion block 6, and the stable assembly of the connection shell 2 and the modular steel column. There is no need for complex prestress control or high-precision positioning, reducing the on-site construction difficulty and the dependence on the skills of construction workers. By adopting standard part design, the requirements for special materials and complex processes are reduced, and the material cost and processing cost are lowered. At the same time, the simplified operation process reduces the labor cost and time cost, effectively controlling the project cost. The locking mechanism ensures the stable connection between modules, effectively preventing relative slip or angular displacement, improving the overall stiffness and stability of the structure, enhancing the seismic performance, and reducing the risk of structural damage. Through the design of the locking mechanism and the reset mechanism, it is easy for construction workers to operate and maintain, without the need for complex tools or skills, improving the construction efficiency. The reset mechanism realizes the automatic reset function of the locking mechanism, reducing the need for manual intervention and making the connection and unlocking operations between modules more rapid and convenient.
