[0037] An embodiment of the present application provides a prefabricated building, including columns, crossbeams, and connectors. The columns are connected to the ground and extend in a vertical direction away from the ground to be connected to the crossbeams. One end of the connector is fixedly connected to the column and is located at the end of the column away from the ground, and the other end is sleeved with the crossbeam in a direction perpendicular to the vertical direction. The connector is located inside the crossbeam. The connector includes: a fixing portion and a fixing groove. The fixing portion is fixedly connected to the column and is installed in the vertical direction, and is sleeved with the crossbeam in the vertical direction and is located inside the crossbeam. The fixing groove is integrally formed with the fixing portion and is opened at the end of the fixing portion away from the ground and is in close connection with the crossbeam, and the path of the fixing groove is consistent with the vertical direction close to the ground.

[0038] Wherein, in the vertical direction, the crossbeam approaches the connector and is sleeved to form a vertical connection; in the vertical direction, the crossbeam is clamped with the connector at the end close to the ground to form a vertical connection.

[0039] The prefabricated building provided above improves the connection structure of the columns, connectors, and crossbeams. Among them, the connector and the crossbeam are sleeved and matched, and the connecting portion of the crossbeam is connected to the connecting groove of the column, so as to improve the stability of the prefabricated building.

[0040] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0041] Please refer to Figures 1-6 , an embodiment of the present application provides a prefabricated building 100, including a column 10, a crossbeam 20, and a connector 30. The column 10 is connected to the ground and extends in a vertical direction 40 away from the ground to be connected to the crossbeam 20. One end of the connector 30 is fixedly connected to the column 10 and is located at the end of the column 10 away from the ground, and the other end is sleeved with the crossbeam 20 in a direction perpendicular to the vertical direction 40. The connector 30 is located inside the crossbeam 20. The connector 30 includes: a fixing portion 31 and a fixing groove 32. The fixing portion 31 is fixedly connected to the column 10 and is installed in the vertical direction 50, and is sleeved with the crossbeam 20 in the vertical direction 50 and is located inside the crossbeam 20. The fixing groove 32 is integrally formed with the fixing portion 31 and is opened at the end of the fixing portion 31 away from the ground and is in close connection with the crossbeam 20, and the path of the fixing groove 32 is consistent with the vertical direction 40 close to the ground.

[0042] Wherein, in the vertical direction 50, the crossbeam 20 approaches the connector 30 and is sleeved to form a vertical connection; in the vertical direction 40, the crossbeam 20 is clamped with the connector 30 at the end close to the ground to form a vertical connection.

[0043] Specifically, the column 10 serves as the main support structure of the prefabricated building 100, responsible for bearing the weight of the building and transmitting loads. The connection to the ground ensures the stability of the structure, and the extension in the vertical direction 40 provides the basis for connecting with the cross beam 20. The design of the column 10 enables the prefabricated building 100 to have a stable support structure, capable of withstanding external forces and ensuring building safety.

[0044] Furthermore, during the construction process, the column 10 is first fixed to the ground and then extends upward along the vertical direction 40 until it reaches the height for connecting with the cross beam 20. The column 10 is applicable to various types of prefabricated buildings 100, such as residential buildings, commercial buildings, etc., as the main load-bearing structure.

[0045] Still further, the connector 30 is responsible for firmly connecting the column 10 and the cross beam 20 together, ensuring the stability and integrity between the two. The fixing part 31 provides the basis for socket connection, and the fixing groove 32 is fitted and connected with the cross beam 20 to enhance the firmness of the connection. Through the design of the connector 30, the rapid and accurate connection between the column 10 and the cross beam 20 is achieved, improving the construction efficiency and quality of the prefabricated building 100.

[0046] Even further, the fixing part 31 is fixedly connected to the column 10 and installed along the vertical direction 50, and is socketed with the cross beam 20 along the vertical direction 50. The fixing groove 32 is opened at one end of the fixing part 31 away from the ground and is fitted and connected with the cross beam 20, and the path is consistent with the vertical direction 40 close to the ground. The fixing part 31 provides a supporting surface for socketing with the cross beam 20, and the fixing groove 32 enhances the connection stability with the cross beam 20 through the fitted connection. The design of the fixing part 31 and the fixing groove 32 makes the connection more firm and reliable, reduces errors and deviations during the assembly process, and improves the assembly accuracy.

[0047] During the assembly process, the fixing part 31 is first fixedly connected to the column 10, and then the cross beam 20 is socketed on the fixing part 31 along the vertical direction 50. At the same time, the fixing groove 32 is closely fitted with the cross beam 20 to ensure a tight and gapless connection between the two. The fixing part 31 and the fixing groove 32 are applicable to the joints of prefabricated buildings 100 that require high-precision and high-stability connections, such as important load-bearing joints or connection positions 221 with large forces.

[0048] In summary, through the design of features such as the column 10, the connector 30, the fixing part 31, and the fixing groove 32, the prefabricated building 100 achieves a rapid, accurate, and stable assembly process, improving the overall performance and construction quality of the prefabricated building 100. This design scheme shows good application prospects and practical value in various application scenarios.

[0049] In a specific embodiment, the cross beam 20 includes a main body 21, and the main body 21 is sleeved with the fixing part 31 in the vertical direction 50, and the fixing part 31 is located inside the main body 21.

[0050] Specifically, the main body 21 of the cross beam 20 is a main load-bearing component in the prefabricated building 100, responsible for bearing and dispersing the loads from the upper structure. Through the sleeving with the fixing part 31, the main body 21 of the cross beam 20 is stably connected to the column 10, ensuring the stability of the entire structure.

[0051] Furthermore, since the fixing part 31 is located inside the main body 21 of the cross beam 20, this design method enhances the connection strength between the cross beam 20 and the column 10, thereby improving the stability of the entire prefabricated building 100. By sleeving the main body 21 of the cross beam 20 and the fixing part 31, the installation process becomes more simple and rapid, improving the construction efficiency. The design of the main body 21 of the cross beam 20 fully considers the load-bearing requirements and can effectively disperse and bear the loads from the upper part, ensuring the safety of the building.

[0052] Still further, during the construction process of the prefabricated building 100, first install the column 10 to ensure its firm connection to the ground. Then, fix the fixing part 31 of the connecting piece 30 at the end of the column 10 away from the ground. Next, sleeve the main body 21 of the cross beam 20 on the fixing part 31 in the vertical direction 50, so that the fixing part 31 is completely located inside the main body 21 of the cross beam 20. In this way, the cross beam 20 and the column 10 are stably connected through the connecting piece 30.

[0053] Even further, this design method is applicable to various types of prefabricated buildings 100, especially buildings that need to bear large loads or have high requirements for structural stability, such as high-rise residential buildings, commercial complexes, industrial factories, etc. In these application scenarios, the design of the main body 21 of the cross beam 20 can ensure the stability and safety of the structure, meeting the usage requirements of the building.

[0054] In summary, the sleeving design of the main body 21 of the cross beam 20 and the fixing part 31 plays a key role in the prefabricated building 100, not only improving the structural stability and load-bearing capacity, but also simplifying the installation process and improving the construction efficiency. This design scheme has broad application prospects and practical value in practical applications.

[0055] In a specific embodiment, the cross beam 20 includes a connecting block 22, the connecting block 22 is integrally formed with the main body 21, is located on the side of the main body 21 close to the connecting piece 30, and is in fitting connection with the fixing groove 32 and located inside the fixing groove 32 along the vertical direction 40 close to the ground.

[0056] Specifically, the design of the connection block 22 increases the contact area between the cross beam 20 and the connector 30, thereby improving the connection stability between the two. The connection block 22 is located in the contact area between the cross beam 20 and the connector 30, which can effectively disperse the stress between the column 10 and the cross beam 20 and prevent structural damage caused by local stress concentration. The fitting connection between the connection block 22 and the fixing groove 32 provides precise positioning for the connection between the cross beam 20 and the connector 30, ensuring that the two can be accurately connected.

[0057] Furthermore, by enhancing the connection strength between the cross beam 20 and the connector 30, the stability of the entire prefabricated building 100 is improved, enabling it to withstand greater external forces and loads. At the same time, the design of dispersing stress reduces the stress concentration phenomenon in the structure, reduces the risk of structural damage, and thus extends the service life of the building. The precise positioning function of the connecting block 22 and the fixing groove 32 also simplifies the installation process and improves construction efficiency.

[0058] Furthermore, during the construction of the prefabricated building 100, the columns 10 and the connectors 30 are first installed to ensure that the connectors 30 are firmly fixed to the columns 10. Next, the main body 21 of the beam 20 is sleeved on the fixing portion 31 of the connector 30 along the vertical direction 50. At this time, the connecting block 22 on the beam 20 corresponds to the fixing groove 32 of the connector 30. By adjusting the position of the beam 20, the connecting block 22 is fitted and connected to the fixing groove 32 along the vertical direction 40 close to the ground, and is completely located in the fixing groove 32. In this way, the beam 20 and the connector 30 are stably connected.

[0059] Furthermore, it is applicable to various scenarios of prefabricated buildings 100 that require high-strength and stable connections, such as high-rise residential buildings, commercial complexes, industrial plants, etc. In these application scenarios, the stable connection between the cross beam 20 and the connector 30 is crucial to ensure the stability and safety of the entire structure. By adopting the fitting connection method of the connection block 22 and the fixing groove 32, the connection strength can be effectively improved to meet the use requirements of the building.

[0060] In summary, the design of the connecting block 22 in the cross beam 20 plays a key role in the prefabricated building 100, which enhances the connection strength between the cross beam 20 and the connecting piece 30, improves the stability and service life of the structure, and simplifies the installation process. This design has broad application prospects and practical value in practical applications.

[0061] In a specific implementation example, the connection block 22 includes a connection portion 221 and a limiting portion 222. The connection portion 221 is connected to the fixing groove 32 in a vertical direction 40 close to the ground and is located in the fixing groove 32. The limiting portion 222 abuts against one end of the fixing groove 32 away from the column 10 in a vertical direction 50.

[0062] Specifically, the connecting portion 221 is an important component of the connecting block 22, and is designed to be fitted and connected with the fixing groove 32. This connection not only ensures a stable connection between the cross beam 20 and the column 10, but also increases the stability of the entire structure.

[0063] Furthermore, the limiting portion 222 is another key part of the connecting block 22, which is located above the connecting portion 221 and abuts against the top of the fixing groove 32. The main function of the limiting portion 222 is to prevent the cross beam 20 from excessively moving in the vertical direction 50, and ensure that the relative position between the cross beam 20 and the column 10 is stable.

[0064] Furthermore, the contact between the limiter 222 and the fixing groove 32 effectively prevents the cross beam 20 from loosening and displacement in the vertical direction 50, thereby improving the stability of the structure. Under the action of external forces such as earthquakes, the limiter 222 can limit the movement range of the cross beam 20, reduce the vibration amplitude of the structure, and thus improve the earthquake resistance of the building. The setting of the limiter 222 makes the structural layout more reasonable and avoids safety hazards caused by structural looseness.

[0065] Furthermore, during the construction of the prefabricated building 100, the fixing portion 31 of the connector 30 is first fixedly connected to the column 10. Then, the main body 21 of the beam 20 is sleeved with the fixing portion 31 along the vertical direction 50, and the connecting block 22 moves with the main body 21 of the beam 20. When the connecting block 22 reaches the position of the fixing groove 32, the connecting portion 221 is fitted and connected with the fixing groove 32 along the vertical direction 40 close to the ground, and is completely located in the fixing groove 32. At the same time, the limiting portion 222 abuts against the end of the fixing groove 32 away from the column 10 along the vertical direction 50, so as to achieve a stable connection between the beam 20 and the column 10.

[0066] In summary, the design of the connection portion 221 and the limit portion 222 in the connection block 22 plays a key role in the prefabricated building 100. They together enhance the stability and connection strength of the structure and improve the safety of the building. This structure has broad application prospects and practical value in practical applications.

[0067] In a specific implementation example, the column 10 is provided with a connection groove 11 , and the connection groove 11 is connected to the connection portion 221 for reinforcing the connection between the column 10 and the beam 20 .

[0068] Specifically, the design of the connecting groove 11 is mainly to provide an additional connection point to enhance the connection stability between the upright column 10 and the cross beam 20. Through the combination of the connecting groove 11 and the connecting part 221, the connection between the upright column 10 and the cross beam 20 can be made more firm, thereby improving the structural strength of the entire prefabricated building 100.

[0069] Furthermore, the combined use of the connecting groove 11 and the connecting part 221 can effectively reduce the swaying and displacement in the structure and improve the stability of the overall structure. By increasing the connection points, the connection strength between the upright column 10 and the cross beam 20 can be significantly enhanced, enabling the structure to withstand greater external forces. The design of the connecting groove 11 makes the installation process more convenient, reduces the possible errors during the installation process, and improves the construction efficiency.

[0070] Still further, the connecting part 221 is a part of the connecting block 22 of the cross beam 20, and it is connected in cooperation with the connecting groove 11 to ensure a firm connection between the cross beam 20 and the upright column 10. The shape and size of the connecting part 221 are designed to match the connecting groove 11 to achieve a tight fit and a stable connection.

[0071] Even further, the precise design of the connecting part 221 can ensure a tight fit with the connecting groove 11, reduce the errors during the installation process, and improve the connection accuracy. The combined use of the connecting part 221 and the connecting groove 11 can ensure a more reliable connection between the cross beam 20 and the upright column 10 and reduce the potential safety hazards caused by loose connections. Through the connection between the connecting part 221 and the connecting groove 11, the integrity between the upright column 10 and the cross beam 20 can be enhanced, and the collaborative working ability of the entire structure can be improved.

[0072] In summary,

[0073] During the construction process of the prefabricated building 100, first install the upright column 10 and open the connecting groove 11 on the upright column 10. Then, align the connecting block 22 of the cross beam 20 with the connecting groove 11 on the upright column 10 to ensure that the connecting part 221 can be completely inserted into the connecting groove 11. Then, through appropriate fastening measures (such as bolt connection, welding, etc.), fix and connect the connecting part 221 with the connecting groove 11. In this way, a firm connection relationship is formed between the cross beam 20 and the upright column 10.

[0074] In a specific embodiment, the depth of the fixing groove 32 is denoted as x, the depth of the connecting groove 11 is denoted as y, and the length of the connecting part 221 is denoted as z, satisfying the relationship:

[0075] x + y ≤ z.

[0076] Specifically, the depth x of the fixing groove 32 determines the depth to which the connecting portion 221 can be inserted, thereby affecting the connection strength between the connecting member 30 and the cross beam 20. An appropriate depth can ensure that the connecting portion 221 is firmly inserted into the fixing groove 32, improving the structural stability.

[0077] Furthermore, the depth y of the connecting groove 11 is the depth of the notch opened on the column 10, which determines the connection tightness between the connecting portion 221 and the column 10. A deeper connecting groove 11 can provide stronger support force to ensure a more secure connection between the connecting portion 221 and the column 10.

[0078] Still further, the length z of the connecting portion 221 is the length of the part of the connecting block 22 that is used to insert into the fixing groove 32 and the connecting groove 11. Its length must be long enough to ensure that it can be inserted into both the fixing groove 32 and the connecting groove 11 simultaneously to form a stable connection. By ensuring that x + y ≤ z, the connecting portion 221 can be inserted into the fixing groove 32 and the connecting groove 11 simultaneously to achieve a three-dimensional stable connection, thereby improving the structural stability of the entire prefabricated building 100. The depth matching of the connecting portion 221 in the fixing groove 32 and the connecting groove 11 enhances the shear resistance and tensile resistance of the connection point, making the connection between the column 10 and the cross beam 20 more reliable and less likely to loosen or fall off. The reasonable design makes the installation process of the connecting member 30 more simple and fast, reducing the adjustment work during installation and improving the construction efficiency.

[0079] Even further, during the construction process of the prefabricated building 100, first ensure that the fixing portion 31 of the connecting member 30 is firmly connected to the column 10, then sleeve the main body 21 portion of the cross beam 20 onto the fixing portion 31 so that the connecting portion 221 on the connecting block 22 can be smoothly inserted into the fixing groove 32. Next, extend the connecting portion 221 further into the connecting groove 11 on the column 10 until the condition of x + y ≤ z is met. Finally, through appropriate fastening measures, ensure the stable position of the connecting portion 221 in the fixing groove 32 and the connecting groove 11 to form a firm connection.

[0080] In a specific embodiment, the width of the connecting groove 11 is denoted as a, the width of the connecting portion 221 is denoted as b, and the width of the limiting portion 222 is denoted as c, satisfying the relationship:

[0081] b ≤ a < c.

[0082] Specifically, the width a of the connection groove 11 determines the installation space size of the connection part 221 on the column 10. An appropriate width a of the connection groove 11 can ensure that the connection part 221 is firmly embedded in the connection groove 11, while avoiding an overly wide structure that is not compact. The width b of the connection part 221 directly affects its mating tightness with the connection groove 11. The width b of the connection part 221 should be less than or equal to the width a of the connection groove 11 to ensure that the connection part 221 can be smoothly inserted into the connection groove 11. The width c of the limiting part 222 plays a role in fixing and limiting. It should be greater than the width b of the connection part 221 and less than the width a of the connection groove 11 to ensure that the limiting part 222 can closely fit on the edge of the connection groove 11 and prevent the connection part 221 from sliding or falling off in the groove.

[0083] Furthermore, by satisfying the relationship b ≤ a < c, the connection part 221 can maintain a stable position in the connection groove 11, while the limiting part 222 can prevent the connection part 221 from being displaced when subjected to external forces, thereby improving the stability of the connection. A reasonable width design makes the connection between the connector 30 and the column 10 more compact, reduces unnecessary material waste, and also improves the aesthetics of the overall structure. An appropriate width fit makes the installation and disassembly of the connector 30 more convenient and improves the construction efficiency.

[0084] Still further, during the construction process of the prefabricated building 100, first align the connection part 221 of the connector 30 with the connection groove 11 on the column 10, and then insert the connection part 221 into the connection groove 11. Since b ≤ a, the connection part 221 can smoothly enter the connection groove 11. Then, the limiting part 222 closely fits with the edge of the connection groove 11. Since c > b, the limiting part 222 can play a role in fixing and limiting to prevent the connection part 221 from sliding in the groove. Finally, through appropriate fastening measures, ensure that the connection between the connector 30 and the column 10 is firm and reliable.

[0085] In a specific embodiment, a first chamfer 321 is provided in the fixing groove 32, and the first chamfer 321 is located between the fixing groove 32 and the fixing part 31.

[0086] Specifically, the presence of the first chamfer 321 makes it easier to align the fixing groove 32 and the connection block 22 during the assembly process, reduces the assembly difficulty, and improves the assembly efficiency. During the assembly process, stress concentration often occurs at the contact between components. The design of the first chamfer 321 can disperse these stresses and reduce the risk of component damage caused by stress concentration. By optimizing the assembly process and reducing stress concentration, the first chamfer 321 helps to enhance the stability of the overall structure and improve the durability of the prefabricated building 100.

[0087] Furthermore, optimizing the assembly process means reducing the assembly time, thus improving production efficiency. Reducing the risk of component damage means lowering the costs of repair and replacement parts, thereby reducing the overall cost. The enhanced stability and durability of the prefabricated building 100 can improve user satisfaction and trust in the product.

[0088] Furthermore, during the assembly process of the prefabricated building 100, when the connecting block 22 of the crossbeam 20 docks with the fixing groove 32, due to the existence of the first chamfer 321, the connecting block 22 can enter the fixing groove 32 more smoothly. As the connecting block 22 goes deeper, the first chamfer 321 gradually fits with the second chamfer 322, forming a smooth transition. Eventually, the connecting block 22 completely enters the fixing groove 32 and is tightly connected to the fixing portion 31.

[0089] In a specific embodiment, the connecting block 22 is provided with a second chamfer 322. The second chamfer 322 is located at one end of the connecting block 22 that fits and connects with the fixing groove 32, and the second chamfer 322 fits and connects with the first chamfer 321.

[0090] Specifically, the existence of the second chamfer 322 enables the connecting block 22 to enter the fixing groove 32 more smoothly during the assembly with the fixing groove 32, reducing the assembly difficulty and improving the assembly efficiency. The fitting connection between the second chamfer 322 and the first chamfer 321 reduces the friction area during the assembly process, reduces the component wear caused by friction, and thus extends the service life of the components.

[0091] Furthermore, by optimizing the assembly process and reducing wear, the second chamfer 322 helps to enhance the connection stability between the connecting block 22 and the fixing groove 32, improving the stability of the overall structure.

[0092] Furthermore, due to the optimized assembly process, the production efficiency of the prefabricated building 100 is significantly improved. Reducing the costs of component replacement and maintenance caused by friction and wear reduces the overall production cost.

[0093] Furthermore, during the assembly process of the prefabricated building 100, when the connecting block 22 docks with the fixing groove 32, due to the existence of the second chamfer 322, the connecting block 22 can enter the fixing groove 32 more smoothly along the guidance of the first chamfer 321. As the connecting block 22 goes deeper, the second chamfer 322 gradually fits with the first chamfer 321, forming a smooth transition. Eventually, the connecting block 22 completely enters the fixing groove 32 and is tightly connected to the fixing portion 31.

[0094] In a specific embodiment, the connecting member 30 is made of high-strength steel.

[0095] Specifically, high-strength steel has excellent tensile, compressive, and flexural properties, which can significantly improve the overall structural strength of the prefabricated building 100 and ensure its stability and safety under various environmental conditions. High-strength steel has excellent corrosion resistance and fatigue resistance, and can resist deformation and wear during long-term use, thereby extending the service life of the prefabricated building 100.

[0096] Furthermore, although high-strength steel has high strength, its density is relatively low. Therefore, using high-strength steel as the connecting member 30 can reduce the overall weight of the building while ensuring strength, which is beneficial to reducing the cost of the foundation project.

[0097] Moreover, the use of high-strength steel connecting member 30 can significantly improve the seismic resistance, wind resistance and other properties of the prefabricated building 100, ensuring safety under extreme weather conditions. Although the price of high-strength steel is relatively high, since it can reduce its own weight and extend the service life, it can reduce the maintenance cost during long-term use and optimize the total cost. High-strength steel can be recycled and reused, which conforms to the development trend of green buildings and is beneficial to reducing environmental pollution caused by construction waste.

[0098] Even further, during the construction process of the prefabricated building 100, the high-strength steel connecting member 30, as a key component, plays an important role in connecting the column 10 and the cross beam 20. First, according to the design requirements, the high-strength steel is processed into a connecting member 30 with a fixing part 31 and a fixing groove 32. One end of the connecting member 30 is fixedly connected to the column 10, and the other end is sleeved with the cross beam 20. During this process, the fixing part 31 of the connecting member 30 is sleeved with the cross beam 20 in the vertical direction 50, and the fixing groove 32 is fitted and connected with the connecting block 22 of the cross beam 20. With the clamping connection between the cross beam 20 and the connecting member 30 completed, the structure of the entire prefabricated building 100 is formed and maintained stable.

[0099] Thus, a prefabricated building 100 provided above improves the connection structure of the column 10, the connecting member 30, and the cross beam 20. Among them, the connecting member 30 and the cross beam 20 are sleeved and matched, and the connecting part 221 of the cross beam 20 is connected to the connecting groove 11 of the column 10, so as to improve the stability of the prefabricated building 100.

[0100] The above are only the implementation manners of the present application. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present application, but these all belong to the protection scope of the present application.
