Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, and more particularly to a cabin-type prefabricated building. Background Technology

[0002] Prefabricated modular buildings are being widely used in various fields such as emergency mobile storage and agricultural product processing. They possess significant advantages, including mobility, relocation, replicability, and fixed-location deployment, which enable them to play a crucial role in practical applications. However, several issues regarding their mobility and relocation capabilities remain to be addressed.

[0003] In terms of hoisting, the traditional hoisting and transportation method is similar to that of containers, which involves setting two forklift fork extension slots on the bottom frame of the modular building and installing standard container corner fittings at each right angle of the frame, using one or two cranes for lifting. While this method offers good structural strength and a high degree of integration, it also brings a series of drawbacks. First, its disassembly and assembly performance is poor, limiting the flexible assembly and disassembly capabilities of the modular building. This makes disassembly and assembly operations extremely inconvenient. Furthermore, removing the container corner fittings can cause significant damage to the main structure of the modular building, increasing the difficulty of subsequent maintenance and reuse. Utility Model Content

[0004] The main purpose of this application is to provide a modular prefabricated building that addresses the technical problems of flexible assembly and disassembly performance and easy damage during disassembly of existing modular prefabricated buildings.

[0005] To achieve the above objectives, this application provides a modular prefabricated building, including a building body and a plurality of hoisting structures. The plurality of hoisting structures are respectively connected to the bottom corners of the bottom surface of the building body. Each hoisting structure includes a first hoisting member, a second hoisting member, and a third hoisting member. The first hoisting member and the third hoisting member are connected through the second hoisting member. The first hoisting member and the third hoisting member are connected to the bottom surface of the building body. One end of the first hoisting member extends away from the building body and has a hoisting hole.

[0008] Optionally, the upper flange of the second lifting member is used to connect the upper flanges of the first lifting member and the third lifting member, the lower flange of the second lifting member is used to connect the lower flanges of the first lifting member and the third lifting member, one end of the web of the second lifting member extends into the groove of the first lifting member and connects to the first lifting member, and the other end of the web of the second lifting member extends into the groove of the third lifting member and connects to the third lifting member.

[0009] Optionally, the number of lifting holes is two, and the two lifting holes are arranged parallel and symmetrically on the upper flange plate of the first lifting member.

[0010] Optionally, the lifting hole is elongated.

[0011] Optionally, the modular building further includes a fixing structure, which includes a fixing plate and a limiting member. The fixing plate is connected to a transport vehicle for transporting the modular building, and the limiting member is connected to the bottom surface of the building body.

[0015] The beneficial effects that this application can achieve are:

[0016] This application proposes a modular prefabricated building system. A second lifting member enhances the connection stability between the first and third lifting members, allowing them to share the weight of the building body. This ensures the reliability of the connection between the lifting structure and the building body, enabling them to work collaboratively and maintain the stability of the modular prefabricated building during lifting and transportation. Furthermore, unlike standard container corner fittings, the installation and disassembly of the modular prefabricated building does not require complex operations to separate the connection from the building body. The lifting structure in this invention does not limit the flexible assembly and disassembly performance of the modular prefabricated building, making it easy to assemble and disassemble without the need for large and complex equipment, reducing the requirements for site and equipment and further improving assembly and disassembly efficiency. Simultaneously, the lifting structure can be relatively easily removed from the building body, reducing damage caused during the disassembly of the modular prefabricated building.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In existing technologies, standard container corner fittings are typically welded tightly to the modular building frame or connected via high-strength bolts at the right angles (i.e., the intersections of the main beams of the frame structure) to form a highly integrated structure. This connection method makes the standard container corner fittings an integral part of the modular building frame, making them difficult to disassemble and cumbersome to install, thus limiting the flexibility of disassembling the modular building frame. Furthermore, disassembly requires handling complex welding points or bolt connections, which can easily cause significant damage to the main structure of the modular building frame, increasing the difficulty of subsequent maintenance and reuse.

[0027] Therefore, in order to solve the technical problems of flexible assembly and disassembly performance and easy damage during disassembly of existing modular prefabricated buildings, this application proposes a new modular prefabricated building.

[0028] Reference Figures 1 to 3 A modular prefabricated building includes a building body 1 and a plurality of hoisting structures 2. The hoisting structures 2 are respectively connected to the bottom corners of the bottom surface of the building body 1. The hoisting structure 2 includes a first hoisting member 3, a second hoisting member 4 and a third hoisting member 5. The first hoisting member 3 and the third hoisting member 5 are connected through the second hoisting member 4. The first hoisting member 3 and the third hoisting member 5 are connected to the bottom surface of the building body 1. One end of the first hoisting member 3 extends away from the building body 1 and has a hoisting hole 10.

[0029] It should be noted that the first lifting component 3, as the main lifting connector, is secured to the lifting rope 9 via the lifting hole 10 at its extended end. The second lifting component 4, as an intermediate connector in the lifting structure 2, strengthens the connection stability between the first lifting component 3 and the third lifting component 5. The third lifting component 5, as a balancing component, shares the weight of the building body 1 with the first lifting component 3 and balances the lifting force horizontally, preventing the modular building from tilting or swaying. Both the first lifting component 3 and the third lifting component 5 are connected to the bottom surface of the building body 1, providing a wider support area and a more stable point of force in the horizontal direction. During lifting, the lifting force can be evenly distributed on the first lifting component 3 and the third lifting component 5, effectively preventing the building body 1 from tilting or deforming due to excessive force at a single point. For example, when the crane lifts, the tension transmitted through the lifting rope 9 is distributed to the connection points between the first lifting component 3 and the third lifting component 5 and the bottom surface of the building body 1, keeping the entire modular prefabricated building stable during vertical ascent and greatly improving structural stability during lifting.

[0030] Specifically, when transporting the modular building, firstly, two cranes are driven to appropriate positions at the front and rear ends of the modular building, respectively, ensuring that the cranes' operating radius can cover the corresponding lifting points at the ends of the modular building. Then, for the lifting points at the front end of the modular building, the lifting rope 9 is lowered using the hook of the front crane and tied to the extended outer edges of the two front first lifting components 3. Similarly, for the lifting points at the rear end of the modular building, the rear crane performs the same rope 9 tying operation, tying the rope 9 to the extended outer edges of the two rear first lifting components 3. After both cranes have completed the rope 9 tying and verified that everything is correct, both cranes simultaneously and slowly raise their hooks, applying lifting force. As the modular building is gradually lifted to a certain height, the cranes adjust the boom extension angle and hook height according to the position and height of the transport vehicles 8, slowly lifting the modular building above the transport vehicles 8. During the hoisting process, the two cranes must maintain coordinated movements to ensure that the modular building remains level and does not collide with surrounding obstacles. Once the modular building is accurately positioned above the transport vehicle 8, the two cranes will work together again to slowly lower the hooks and place the modular building smoothly onto the transport vehicle 8.

[0031] The modular building proposed in the above embodiment strengthens the connection stability between the first lifting component 3 and the third lifting component 5 through the second lifting component 4. This allows the first lifting component 3 and the third lifting component 5 to share the weight of the building body 1, ensuring the reliability of the connection between the lifting structure 2 and the building body 1. This enables them to work collaboratively and maintain the stability of the modular building during lifting and transportation. Furthermore, the installation and disassembly of the modular building do not require the complex operations of handling standard container corner fittings to separate the connection from the building body 1. The lifting structure 2 in this invention does not limit the flexible assembly and disassembly performance of the modular building, making it easy to assemble and disassemble without the need for large and complex equipment, reducing the requirements for site and equipment, and further improving assembly and disassembly efficiency. Simultaneously, the lifting structure 2 can be relatively easily removed from the building body 1, reducing damage caused during the disassembly of the modular building.

[0032] As an feasible approach, refer to Figure 2 The first lifting component 3, the second lifting component 4, and the third lifting component 5 are all made of H-shaped profiles.

[0033] It should be noted that the H-type profile includes two flanges and a web perpendicular to the two flanges, and the flange located at the top is called the upper flange, and the flange located at the bottom is called the lower flange.

[0034] Specifically, due to the structural characteristics of the H-shaped profile, the force is distributed and transmitted along the upper flange, lower flange, and web. The upper and lower flanges mainly bear the lateral tensile and compressive forces, while the web bears the vertical shear forces, evenly distributing the force throughout the entire lifting structure 2. Simultaneously, the H-shaped profile has a high moment of inertia and flexural modulus, effectively resisting bending deformation when subjected to lifting forces. Its optimized cross-sectional shape allows it to provide better mechanical properties than other profile shapes with the same material usage.

[0035] As an feasible approach, refer to Figure 2 The first lifting component 3 and the third lifting component 5 are arranged in parallel.

[0036] Specifically, when the lifting force is applied to the lifting hole 10 at the extension end of the first lifting member 3, since the first lifting member 3 and the third lifting member 5 are arranged in parallel, the force will be evenly transmitted to the building body 1 along these two lifting members. The parallel arrangement makes the direction of the force relatively stable during the transmission process, and there will be no force decomposition or reversal due to different lifting member angles.

[0037] As an feasible approach, refer to Figure 2 and Figure 3 The upper flange of the second lifting member 4 is used to connect the upper flanges of the first lifting member 3 and the third lifting member 5. The lower flange of the second lifting member 4 is used to connect the lower flanges of the first lifting member 3 and the third lifting member 5. One end of the web of the second lifting member 4 extends into the groove of the first lifting member 3 and is connected to the first lifting member 3. The other end of the web of the second lifting member 4 extends into the groove of the third lifting member 5 and is connected to the third lifting member 5.

[0038] It should be noted that the grooves of the first lifting component 3 and the third lifting component 5 refer to the grooves formed between their respective upper flange, web, and lower flange.

[0039] Specifically, when the lifting force is applied to the lifting hole 10 of the first lifting member 3, the force is first transmitted along the first lifting member 3. The upper flange of the first lifting member 3 transmits part of the lateral tensile force to the upper flange of the second lifting member 4, and the lower flange similarly transmits the lateral pressure or tensile force. The upper and lower flanges of the second lifting member 4 then transmit the force to the corresponding flanges of the third lifting member 5, realizing the lateral transmission of force between the first lifting member 3 and the third lifting member 5. At the same time, one end of the web of the second lifting member 4 extends into the groove of the first lifting member 3 and connects with the first lifting member 3. The vertical force on the first lifting member 3 is transmitted to the second lifting member 4 through its web, and then the other end of the web of the second lifting member 4 transmits the force to the third lifting member 5. Finally, the force forms a complete transmission path in the entire lifting structure 2, ensuring that the weight of the building body 1 and the external load can be effectively transmitted to the lifting equipment.

[0040] As an feasible approach, refer to Figure 2There are two lifting holes 10, which are arranged in parallel and symmetrically on the upper flange plate of the first lifting component 3.

[0041] Specifically, when using the lifting rope 9 to connect to the lifting hole 10 for lifting operations, one end of the lifting rope 9 first passes through one of the lifting holes 10 of the first lifting member 3, then wraps around the first lifting member 3 once and exits through the other lifting hole 10, finally converging at the lifting point for winding and tightening. The two parallel and symmetrically arranged lifting holes 10 enable the lifting force to be evenly distributed on the first lifting member 3, achieving a balance of force in the horizontal direction.

[0042] As an feasible approach, refer to Figure 2 The lifting hole 10 is elongated.

[0043] Specifically, the elongated lifting hole 10 allows for a certain amount of movement of the lifting rope 9 or hook within the hole. During hoisting operations, if the hook cannot be precisely aligned with the center of the lifting hole 10 due to operational errors or environmental factors, the elongated lifting hole 10 allows the hook to adjust its position within a certain range, still ensuring effective connection with the lifting hole 10, thus facilitating smooth hoisting. For example, during the hoisting process, the building body 1 may tilt or sway at a certain angle due to wind, the starting and stopping of the hoisting equipment, etc. The elongated lifting hole 10 can adapt to such angle changes, avoiding additional stress on the hoisting structure 2 or connection failure due to the shape limitation of the lifting hole 10.

[0044] As an feasible approach, refer to Figure 1 , Figure 4 and Figure 5 The modular building also includes a fixing structure, which includes a fixing plate 6 and a limiting member 7. The fixing plate 6 is connected to the transport vehicle 8 used to transport the modular building, and the limiting member 7 is connected to the bottom surface of the building body 1. Both ends of the fixing plate 6 are provided with notches that match the hoisting structure 2, and the fixing plate 6 is provided with limiting grooves that match the limiting member 7.

[0045] Specifically, when placing the modular building, the lifting structure 2 fits perfectly into the notch, while the limiting component 7 enters the corresponding limiting groove on the fixing plate 6. That is, the lifting structure 2, the limiting component 7, and the fixing plate 6 work together to form a clamping positioning structure, thus positioning and fixing the modular building on the transport vehicle 8. This prevents the building body 1 from shifting forward, backward, or left and right during vehicle movement. For example, when the vehicle accelerates, decelerates, or turns, the building body 1 may tend to move due to inertia, but the cooperation of the limiting component 7 and the limiting groove effectively blocks this movement, ensuring that the building body 1 remains in a fixed position, thereby guaranteeing the safety and stability of transportation.

[0046] As an feasible approach, refer toFigure 1 and Figure 4 The limiting component 7 is set along the width direction of the building body 1.

[0047] Specifically, when the limiting member 7 is installed along the width direction of the building body 1, it can provide stable support force from the width direction of the building body 1. That is, the limiting member 7 can both work with the hoisting structure 2 to limit the building body 1 and work with the hoisting structure 2 to support the building body 1. There is no need to set up an additional special support structure, saving space at the bottom of the building body 1.

[0048] As an feasible approach, refer to Figure 1 and Figure 4 The number of limiting components 7 is several, and the several limiting components 7 are evenly distributed along the length direction of the building body 1.

[0049] Specifically, several limiting members 7 are evenly distributed along the length of the building body 1, so that various external forces experienced by the building body 1 during transportation can be evenly distributed to each limiting member 7. For example, when the vehicle brakes suddenly, the forward inertial force of the building body 1 can be evenly transmitted to the fixed plate 6 through the evenly distributed limiting members 7, avoiding local structural damage or deformation caused by the concentration of force in a few parts. Each limiting member 7 shares a relatively balanced force, thereby extending the service life of the fixed structure and the building body 1, and ensuring structural safety during transportation.

[0050] As an feasible approach, refer to Figure 1 and Figure 4 The limiting component 7 can be installed at the intersection of the structural longitudinal beams and structural transverse beams of the bottom frame of the building body 1.

[0051] As one feasible approach, the fixing structure also includes several connecting rings (not shown in the figure), which are connected to the fixing plate 6 and are evenly distributed along the outer periphery of the fixing plate 6.

[0052] Specifically, during the transport of the modular building, one end of each fastening strap is wrapped around the lifting structure 2 and the limiting component 7, while the other end of the straps is fixed to the connecting ring. This connects the lifting structure 2 to the connecting ring and the limiting component 7 to the connecting ring, securing the building body 1 from multiple angles. During transport, regardless of vertical bumps, horizontal swaying, or other external forces, the modular building remains firmly restrained on the transport vehicle 8. This comprehensive reinforcement method significantly improves the stability of the modular building during transport, effectively preventing displacement, tilting, or falling, thus ensuring transport safety.

[0053] It should be noted that connecting rings may be installed at regular intervals (e.g., 1-2 meters) to facilitate the selection of the appropriate number and placement of connecting rings for fastening operations based on the size and weight of the modular assembly building. Near the front and rear of the vehicle, the distribution of connecting rings may be more dense, as these areas are more susceptible to bumps and impacts during transportation and require stronger fastening constraints. Furthermore, connecting rings may come in various forms, commonly including metal rings or threaded metal buckles, to accommodate different types of fastening strap connection methods.

[0054] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
