Description

[Technical Field]

[0001] The present invention relates to the field of modular construction technology, and more particularly to the overall structure of a modular house, its assembly method and on-site installation method. [Background technology]

[0002] Modular houses, also known as container houses or mobile homes, have the characteristics of being quickly constructed, portable, and reusable. Conventional modular houses generally adopt a container-type structure, including end frames, beams, and floor panels, which are assembled in a factory and then transported in a containerized form to the construction site for installation and fixing. However, conventional modular houses have the following main defects:(1) They have low flexibility, and floor panels, window bodies, etc. cannot be rotated, so they can only be built by assembling each module house individually, which results in slow installation speeds and high transportation costs. (2) When building a high-rise or super-tall building, the load-bearing capacity of the beam rods is weak when multiple module houses are stacked one on top of the other. (3) When lifting and joining the upper and lower module houses, it is difficult to quickly position and connect the upper module house to the lower module house. (4) The air conditioner outdoor unit needs to be installed on-site, which is time-consuming and labor-intensive. (5) Curtains are generally installed on the outer surface of the glass, which is not wind-resistant, easily damaged, difficult to customize, and takes up space. When installed inside the glass, air is easily leaked through the glass and is difficult to inspect and repair. (6) The traditional prefabrication of module houses in factories mainly involves the manufacture of modules such as wall panels, roofs, floors, doors and windows, and then adding electrical circuits, piping arrangements, and interior decorations. However, the module house (7) When transporting conventional modular houses, they can only be transported individually, and when they are stacked, their load-bearing capacity is low. For example, when transporting by sea, multiple modular houses must be stacked, and the corner members are not strong enough, resulting in low load-bearing capacity. (8) When constructing conventional modular houses on site, the movable floor panels are stored and then lifted up, and then lifted to the desired position and then turned over to open. This method takes time and effort to lower the floor panels at high altitudes, and the movable floor panels are prone to loosening and turning downward during the lifting process, resulting in a high risk of accidents. (9) Traditional rooftop machinery rooms are generally designed to fit the structure of the house and do not match the dimensions of the container, resulting in high material transportation costs and slow construction. In addition, solar panels are generally installed separately from the rooftop machinery room, taking up a large amount of space.

[0003] To sum up, the present invention urgently needs to design a new mode of modular frame chamber to solve the above technical problems. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention is to overcome the above-mentioned drawbacks of the prior art and to provide a modular house overall structure, assembly and on-site installation method that has high space utilization, high flexibility, low transportation cost and is easy to assemble.

[0016] Furthermore, before lifting the modular house, the movable floor plate of the modular house is first inverted downward to a horizontal position, and then lifted.

[0017] Furthermore, beam rods are prefabricated on both ends of the movable floor panel, and the movable floor panel is connected to the columns of the end frames of the adjacent modular houses via the beam rods.

[0018] Furthermore, a pier foundation is provided between the modular house located on the bottom layer and the embedded foundation member. The pier foundation adopts a composite structure, with the upper layer made of the same material as the main body of the modular house and the lower layer made of the same material as the embedded foundation member. [Effects of the Invention]

[0019] (1) By installing movable floors and movable windows, container standards can be met during transportation. They can be transported together with the modular house, and when installed on site, they can be inverted and used as part of another modular house. This significantly improves installation speed and reduces transportation costs compared to assembling individual modular houses. (2) By adding auxiliary beam rods in addition to the conventional beam rods, the beam rods and auxiliary beam rods can bear the overall load, greatly improving the structural strength and making it particularly suitable for high-rise or super-high-rise buildings, with safe load-bearing capacity. (3) By setting pin holes and positioning pins on the flange plates of the columns for positioning, the upper modular house can be quickly installed in the designated position, improving the installation speed, and the positioning pins can be removed after positioning. (4) The air conditioner outdoor unit is designed to be both built-in and externally mounted, which not only meets transportation requirements and greatly improves transportation efficiency, but also allows the air conditioner outdoor unit to be directly pushed out and connected on site, eliminating the need to transport the air conditioner outdoor unit separately and install it on site. This greatly simplifies the assembly steps, saving time and effort. (5) The curtain is installed inside the cavity of the hollow glass, so it does not occupy space outside the glass. It can be installed at the same time as the glass during installation, so no additional work is required and it is easy to install. By installing an inspection and repair port and an inspection and repair stop plate, the curtain can be inspected and repaired under the condition that the insulation and sealing of the glass are guaranteed. In addition, combined with the air inlet core, it can prevent air leakage and condensation in the glass cavity, which is especially suitable for hollow glass cavities with large spaces. (6) When a modular house is prefabricated in a factory, components of other modular houses can be placed inside it, such as movable windows and movable floors, making full use of the interior space of the modular house. Materials that need to be installed on-site can be packed together and placed inside the modular frame, which corresponds to the transportation of two modular houses in the prior art. However, the present invention allows the construction of two modular houses by transporting only one modular house. Furthermore, the present invention allows different assembly methods for side-type modules, ladder-type modules, etc., making it highly flexible and applicable in a wide range of applications. (7) The installation of reinforced corner members greatly improves the stability of the house modules when stacked in multiple layers, making them particularly suitable for overseas transportation, and makes them less likely to be deformed when pressed. (8) When installing on site, the movable floor plate is first lowered to a horizontal position, connected to the fixed floor plate, and then lifted up. There is no need to lower it again when working at high altitudes, and there is no need to worry about the movable floor plate loosening and flipping over during the lifting process. This greatly improves the safety factor and saves time and effort when installing on site. (9) The roof machinery room module is designed to meet the dimensions of container transport standards, and a folded functional bracket is installed on the machinery room module, allowing it to be stored during transportation. As a result, the functional bracket can be transported by sea or land together with the machinery room module, reducing transportation costs. When installed on site, it can be placed directly on the roof, eliminating the need for a separate construction like in conventional machinery rooms, greatly reducing the amount of construction work on site. The functional bracket can also be used to unfold and install solar panels or hang clothes, etc. [Brief explanation of the drawings]

[0021] The invention will now be described in more detail with reference to the drawings and specific examples in the specification. [Example]

[0022] As shown in Figure 1, the overall structure of a modular house includes a modular frame body 1 and a movable floor plate 2. The modular frame body 1 includes two end frames 11, a beam body 12 provided between the end frames, and a fixed floor plate 13 provided at the bottom. The movable floor plate 2 is hingedly connected to the fixed floor plate 13, and the movable floor plate 2 can be inverted along the fixed floor plate 13.

[0023] In this embodiment, a beam 12 is installed on one side between the two end frames 11, and no beam is installed on the surface where the movable floor panel is installed. For example, a beam 12 is installed on the upper part of one side of the two end frames, and the beam is installed toward the inside of the end frames, making it easy to install exterior walls on the outside. A plurality of inner link rods 14 are installed at intervals between the beam 12 and the fixed floor panel 13. Braces 15 are installed between both end frames 11 and the upper beam 12. One side of the bottom fixed floor panel 13 is directly connected to the prefabricated beam, and the other side is connected to the movable floor panel 2 via a hinge. The movable floor panel 2 can be flipped 90° along the fixed floor panel and flipped upward to form a side wall of the module frame 1, or lowered to a horizontal position to form the bottom panel of another space.

[0024] As shown in Figure 2, in this embodiment, the end frame 11 includes two columns 111 and an upper cross beam 112 and a lower cross beam 113 connected between the columns. One column has a rectangular cross section, while the other has a square or nearly square cross section. Both the top and bottom surfaces of the columns are provided with flange plates 114, which cover the surfaces of the columns and enable threaded connections between the columns of the upper and lower module frames. For flange plates with large areas, a hole may be drilled in the center. For example, the screw holes in the flange plate may be positioned around the outer edge of the flange plate, with a hole drilled in the middle of the flange plate. In this way, the cut plate can be reused for other purposes, thereby saving material. Lifting holes 115 are provided on both sides of the top of the upper cross beam 112, making it easy to lift the modular house. In this embodiment, the corner members are preferably designed as removable corner members 5, which are used during transportation and are removed for on-site installation. However, removing the corner members would prevent lifting. Therefore, lifting holes 115 are provided in the upper cross beam to enable on-site lifting of the modular house. Preferably, the structure of the lifting holes 115 is the same as that of the lifting holes in the corner members. Prefabricated connection seats 116 are provided on both the side and end surfaces of the columns, facilitating screw connections with other components. In this embodiment, the end frame 11 is a prefabricated structure; that is, the columns, cross beams, flange plates, and all connection seats are all prefabricated together in the factory to form the end frame. Furthermore, a fire-resistant layer 117 is provided on the columns and cross beams of the end frame.

[0025] As shown in Figures 3 and 4, the flange plate of the column is further provided with pin holes 118. When connecting the upper and lower modular houses, positioning pins 3 are inserted into the pin holes 118 of the lower modular house. When lifting the upper modular house above the lower modular house, the pin holes on the lower end surfaces of the columns of the upper modular house are inserted through the positioning pins of the lower modular house to position the upper and lower modular houses. After the upper modular house is placed in position, the positioning pins are removed, and the columns of the upper and lower modular houses are then fastened together with screws using flange plates 114. Furthermore, when positioning the bottom modular house to the ground, the bottom surface of the column of the bottom modular house is also positioned using the positioning pins 119 and pin holes 118, respectively. This positioning method enables quick positioning and installation of the upper and lower modular houses.

[0026] The modular house of this embodiment can be used as a residential house, a ladder-type house module, a machine room module, etc. For example, when used as a ladder-type house module, stairs and elevators can be installed inside the module frame, and when used as a machine room module, power-consuming devices and the like are installed inside the module frame and the machine room module is placed on the roof. Regardless of the type of construction used, all of them meet container transport standards and can be transported by sea or land, and on-site installation is similar to assembling building blocks, making transportation and installation easy and saving time and labor.

[0027] As shown in Figure 5, in this embodiment, a ceiling group 3 is provided on top of the module frame 1, and a suspended ceiling group 4 is provided below the ceiling group 3, with air, water, and electrical equipment and piping arranged between the ceiling group 3 and the suspended ceiling group 4, and transported together with the module house. Here, the suspended ceiling group 4 includes suspended ceiling panels 41, suspended ceiling retaining plates 42, and a suspended ceiling frame 43, and can be used to place equipment such as a new fan or air conditioner inside the suspended ceiling frame 43, and the ceiling group 3 is installed above the suspended ceiling frame.

[0028] As shown in Figures 6 to 8, in this embodiment, the fixed floor plate 13 at the bottom of the upper module frame and the ceiling group 3 of the lower module frame located below it can be prefabricated in a factory and connected together, and the entire structure can be transported or installed on site. Alternatively, a movable floor plate is lowered and connected to the ceiling group of the lower module frame located below it via a connection assembly 31 for on-site installation. Specifically, the ceiling group includes a plurality of plates joined together, and the long sides of adjacent plates are designed as a two-stage groove structure. After the two-stage groove 32 is locked, a fire-resistant sealing material is filled into the gap. A C-shaped frame 33 is attached to the short side of each plate of the ceiling group. The connection assembly 31 includes a ceiling base 311, a ceiling connection base 312, a ceiling rod 313, and a ceiling connection plate 314. The ceiling base 311 is connected to the movable floor plate 2 and can be prefabricated onto the movable floor plate. The ceiling connection base 312 and the ceiling base 311 are connected by screws. The upper end of the ceiling rod 313 is connected to the ceiling connection base 312, and the lower end of the ceiling rod is connected to the ceiling connection plate 314, which is then connected by screws to the C-shaped frame 33 of the ceiling group of the lower house module. Since the ceiling group below the fixed floor plate 13 is installed adjacent to the ceiling group below the movable floor plate 2, the ceiling connection plate 314 can be extended to the C-shaped frame of the ceiling group below the fixed floor plate, and the ceiling connection plate 314 can be simultaneously screwed between the two adjacent ceiling groups, thereby greatly improving the installation speed.

[0029] It can be understood that the ceiling connecting plate of this embodiment can also be designed as a ceiling hook, so that the C-shaped frame can be directly hooked by the ceiling hook, eliminating the need for screw connection, which is faster to install but less stable than screw connection.

[0030] 9, in this embodiment, beam rods 21 are prefabricated at both ends of the movable floor panel 2, and auxiliary beam rods 22 are installed below the beam rods 21. When multiple modular houses are stacked one on top of the other, for example, the movable floor panel of an upper modular frame is lowered to a horizontal position, and one end of the beam rod 21 is screwed to the column 111 of the end frame of that modular frame via the connecting seat, and the other end of the beam rod 21 is connected to the column of another adjacent modular frame. The auxiliary beam rods 22 are installed on site, and both ends of the auxiliary beam rod 22 are screwed to the column 111 of the adjacent modular frame below, and the auxiliary beam rods 22 and 21 are fixed with bolts. Here, nuts are pre-embedded in the beam rods 21, and bolts are inserted into the beam rods via the auxiliary beam rods 22 and connected to the pre-embedded nuts, forming an integrated structure that meets the overall load-bearing requirements. In other words, in this embodiment, by adding auxiliary beam rods in addition to the conventional beam rods, the beam rods and auxiliary beam rods can bear overall force, significantly improving the structural strength and making it particularly suitable for high-rise or skyscraper buildings.

[0031] In this embodiment, support beams are prefabricated below the movable floor plate 2 and the fixed floor plate 13, and when the movable floor plate is inverted until it is level with the fixed floor plate, the two support beams abut, connect, and are fixed.

[0032] 10, in this embodiment, after the movable floor plate 2 is lowered, it is connected to and fixed with the fixed floor plate 13, that is, floor plate connection seats 21 are installed on the bottom surfaces of the movable floor plate 2 and the fixed floor plate 13, and a connection plate 22 is shared between the two floor plate connection seats, with one bolt passing through the connection plate and connected to the floor plate connection seat of the movable floor plate, and the other bolt passing through the connection plate and connected to the floor plate connection seat of the fixed floor plate, thereby securing the two together. A layer of rock wool 23 is filled in the gap between the movable and fixed floor plates.

[0033] As shown in FIG. 11 , in this embodiment, a modular house further includes a movable window 6, e.g., a residential room. The movable window 6 is connected to a pillar 111 of an end frame 11 via a window hinge 61, and one end of the window hinge 61 is connected to the inside of the pillar 111. The movable window 6 is stored within the modular frame during transportation, allowing the modular house to be transported in accordance with container standards. When installed on site, the movable window 6 is flipped over to form part of another space together with the movable floor panel 2. The movable window 6 may also be a bay window or balcony window. For example, a bay window is hinged to one end frame, and a balcony window is hinged to the other end frame. When installed on site, the window is flipped over to form a new modular house structure together with the movable floor panel 2 as end windows at both ends of another space.

[0034] In this embodiment, at least one end frame 11 is provided with an exterior wall 7, for example, both end frames are provided with exterior walls 7, or one end frame is provided with an exterior wall and the other end frame is directly provided with a balcony window. A window may also be provided on the exterior wall.

[0035] When the modular house of this embodiment is prefabricated in a factory, if air, water, and electrical pipelines such as water supply and drainage pipes, oil smoke vertical pipes, sewage discharge pipes, and outside air pipes are prefabricated within the modular frame, and sanitary hardware such as hand wash basins, toilets, and basins are also prefabricated, then it can be said that all hardware is prefabricated in this invention, and when the house is transported to the site and installed, it is only necessary to connect the air, water, and electrical pipelines between the upper and lower floors. For modular houses that require interior walls, the interior walls 9 are prefabricated within the modular frame in advance at the factory.

[0036] In this embodiment, the fixed floor panels, movable floor panels, and ceiling group all use metal core panels, preferably stainless steel or aluminum, and include an upper panel, a lower panel, and a sandwich layer sandwiched between them, the sandwich layer including a plurality of hollow tube arrays, brazed to the panels, and the plurality of hollow tubes are spaced apart, with a thermal insulation layer provided in the adjacent gaps. As can be appreciated, the sandwich layer of the present invention can also be other spaced apart structures, such as a corrugated cardboard core.

[0037] The specific assembly method of the modular house of this embodiment in the factory includes the following steps.

[0038] Assembly and welding of the modular frame: The end frames 11, fixed floor plates 13, beams 12, and inner link rods 14 are assembled to form the modular frame structure, where the connecting seats on the end frames 11 and the connecting seats on the fixed floor plates 13, the beam rods, and the support beams are all prefabricated on the main body and can be assembled and welded on-site. Furthermore, because the fixed and movable floor plates have a core plate structure, cutting the core plate requires cutting both the front and back sides. The core plate is not a single-layer plate, but has a sandwich layer in the middle with a certain thickness. If cutting directly from the top panel to the bottom panel, the cutting is likely to be inaccurate. Therefore, after cutting the front panel, the plate can be flipped over to the back side and the back panel can be cut. When assembling and welding the core plates to form the floor panels, front and back welding is required.

[0039] Assembling the exterior walls: For modular houses that require exterior walls, the exterior walls are assembled, for example, by installing the exterior wall 7 on the outside of the end frame and installing the side exterior wall on one side of the modular frame beam 12.

[0040] Assembling the fireproof layer: Install the fireproof layer 117 on the columns and cross beams of the front end frame and the rear end frame to encase the columns and cross beams and improve the fireproof performance.

[0041] Assembly of suspended ceiling group: For modular houses requiring suspended ceilings, the suspended ceiling group 4 is assembled on top of the modular frame.

[0042] Assembly of electromechanical devices: Assembly of electromechanical devices and ducts is carried out inside the module frame, and the assembly of the electromechanical devices and ducts can be selectively assembled with the inner wall 9 to perform insertion work.

[0043] Interior assembly: For modular houses that require interior decoration, we assemble bathroom and sanitary hardware and sanitary fixtures and doors inside the module frame.

[0044] Assembly of movable windows: For modular houses requiring movable windows 6, the movable windows can be attached to the inside of the end of the module frame and can be moved in and out along the end frame.

[0045] Assembling the ceiling group: Install the ceiling group 3 above the suspended ceiling group 4.

[0046] Loading of parts: Materials that need to be installed on site are packed together and placed inside the module frame.

[0047] Assembly of the movable floor board: The movable floor board 2 and the fixed floor board 13 are hingedly connected to form an inverted structure. After storing the movable floor board 2, the side boards of the module frame 1 are formed, thereby forming a complete module house.

[0048] Here, if the house is a ladder-type house module, it is not necessary to assemble the suspended ceiling group, the interior sanitary fixtures, the movable window group, and the movable floor boards. Instead, the module frame body can be assembled and welded, followed by the assembly of the exterior walls and the fireproof layer. After the fireproof layer is assembled, the assembly of the electromechanical equipment and pipelines can proceed directly. After the electromechanical equipment is assembled, the doors can be assembled. After the doors are assembled, the parts can be loaded, and after loading, the ceiling group can be assembled, and then waterproofing measures can be taken, packaged, and transported.

[0049] In this embodiment, the modular house assembly process in a factory includes a structural segment, an interior segment, a loading segment, a movable panel segment, and a packaging and shipping segment along the overall assembly direction of the modular house. Each segment's production line, together with a towing and transport system, transports the modular house from its initial working position to its final working position, thereby forming the final modular house structure. For example, the structural segment includes at least three work spaces, each of which assembles end frames, fixed floor panels, beams, etc. to form the initial modular frame structure, with a focus on ensuring dimensional accuracy. The interior segment includes at least six work spaces and is used to complete the interior of the modular frame, primarily including fire protection, suspended ceilings, walls, doors, and air, water, and electrical equipment. Any materials weighing more than 15 kg are lifted using specialized lifting equipment, and each module is moved to the appropriate position for installation. The loading segment includes one loading work space, where materials that need to be installed on-site are centrally packed and transported to the installation site together with the house modules, such as interior wall doors, cabinets, and auxiliary beam rods that need to be installed on-site. The movable plate segment includes one movable plate workspace, which is used to weld the movable and fixed floor panels together with hinges, then rotate them 90 degrees using a half-door machine to clamp and secure them in place. The packaging and shipping segment includes a film protection workspace and a shipping workspace. The film protection workspace is used to wrap the completed modular houses in coated fabric and fasten them with nylon ropes, and the shipping workspace is used to lift the completed modular houses onto trucks and send them to the installation site or buffer area. [Example]

[0050] As shown in Figures 12 and 13, based on Example 1, a movable part for connecting an air conditioner outdoor unit 71 is provided in the exterior wall cavity of this example, and the air conditioner outdoor unit 71 can be selectively built into the exterior wall cavity or extend along the exterior wall cavity. When the modular house is transported, the air conditioner outdoor unit 71 is installed in the exterior wall cavity, and when it is installed on site, the air conditioner outdoor unit 71 extends along the exterior wall cavity.

[0051] Here, the movable part may be a removable structure or a push-pull structure. In the case of a removable structure, it can be fixed and removed using a screw assembly 74. For example, an outdoor unit bracket 72 is provided at the bottom of an air conditioner outdoor unit 71, which is screw-fixed to a screw assembly in an exterior wall cavity via the outdoor unit bracket 72. When a portion of the outdoor unit is pushed out of the exterior wall cavity, the air conditioner outdoor unit is removed and pushed into an air conditioner grille 73 connected to the exterior of the exterior wall. The air conditioner grille 73 is then installed on-site, with the inner portion of the outdoor unit bracket 72 of the air conditioner outdoor unit connected to the screw assembly 74 and the outer portion of the outdoor unit fixed to the air conditioner grille via connecting parts. In the case of a push-pull structure, a sliding rail structure may be designed, i.e., two sliding rails are provided in the exterior wall cavity. The sliding rails are connected to a push-pull plate. The outdoor unit bracket of the air conditioner outdoor unit is fixed to the push-pull plate with bolts. The push-pull parts are manually pushed out or retracted, thereby realizing two states of the air conditioner outdoor unit: built-in and external. [Example]

[0052] As shown in FIG. 14, based on Example 1, a hollow glass 8 is provided in the outer wall and / or movable window, a curtain 81 is provided in the cavity of the hollow glass 8, an inspection and repair opening is provided in the hollow glass, an inspection and repair stop plate 82 is provided in the inspection and repair opening, and an air pump core 83 communicating with the hollow glass cavity is provided in the gap between the window frame and the hollow glass.

[0053] Specifically, two pump cores 83 are provided between the window frame and the hollow glass, communicating with the hollow glass cavity. The two pump cores are installed one above the other, with one used for injecting air and the other for exhausting air, thereby forming an air inlet / exhaust passage between the hollow glass cavity and the window frame. The pump cores 83 are preferably valve cores, such as metal valve cores used in automobiles or motorcycles, and have a small outer diameter, typically 3-6 mm, so they do not occupy much space. The two pump cores can be selected for either pumping or exhausting air based on the density of the inert gas used. For example, in this embodiment, argon gas is preferably used. Since the density of argon gas is greater than that of air, the lower pump core is selected for pumping air, and the upper pump core is used for exhausting air.

[0054] A curtain 81 is provided in the cavity of the hollow glass 8, so that it does not need to occupy space outside the glass. Conventional hollow glass has a small cavity space, so it can be treated with a molecular sieve. In this embodiment, a curtain is provided in the glass cavity, so the glass cavity space is large, making it difficult for the molecular sieve to treat the air leakage phenomenon. Therefore, the problem can be effectively solved by providing two air pump cores.

[0055] To allow for inspection and maintenance of the electrical components in the wave curtain or the curtain itself, this embodiment further provides an inspection and repair port at the top of the hollow glass. The inspection and repair port is located between the inner glass (facing the room) of the hollow glass 8 and the window frame. An inspection and repair stopper plate 82 is provided at the inspection and repair port. The inspection and repair stopper plate 82 is designed with a thermal insulation structure and includes thermal insulation padding and an outer panel installed around the thermal insulation padding. The outer panel is equipped with a hem to encase the thermal insulation padding. The lower end of the outer panel is hermetically connected to the inner glass of the hollow glass. An L-shaped member 84 is installed inside, one end of the L-shaped member 84 is glued to the hem of the outer panel and the other end is glued and fixed to the inner wall of the inner glass. The upper end of the outer panel is hermetically connected to the window frame using a sealant and a sealing member. The upper air inlet core is connected to the inspection and repair stopper plate, and the air inlet core 83 penetrates the heat insulation layer of the inspection and repair stopper plate 82 to communicate with the cavity of the hollow glass 8 and is welded and fixed to the outer panel to prevent shaking during air injection and exhaust. If the curtain 81 needs to be repaired, the colloid can be cut and the inspection and repair stopper plate 82 can be removed for repair. After repair, the inspection and repair stopper plate can be kept sealed with the colloid, and air can be again injected and exhausted using the two upper and lower air inlet cores 83. [Example]

[0056] When the modular house is packed and then transported, the transportation method includes:

[0057] (1) Removable corner members 5 are installed at the four corner positions of the front end frame and the rear end frame, specifically at the upper position of the front end face of the pillar body. The removable corner members 5 include a corner member base 51 and a corner member body 52. ​​The structure of the corner member body 52 is the same as that of the standard corner member of a conventional container. It is fixed to the pillar body 111 with screws via the corner member base 51, and the corner member body 52 extends horizontally along the corner member base 51, complying with container transportation standards, specifically as shown in Figure 15.

[0058] (2) If the modular house has a movable window, rotate the movable window to the inside of the module frame. (3) If the module house has an exterior wall and an air conditioner outdoor unit, the air conditioner outdoor unit is stored in the exterior wall cavity. (4) The movable floor panel is stored in the side of the module frame, forming a structure that complies with container transport standards, and is transported in the manner shown in Figure 16.

[0059] As can be seen, when multiple modular houses need to be stacked for transportation, the bottom fixed floor plates of the upper modular frame and the ceiling group of the lower modular frame located below are connected at the factory, and the end frames of the upper modular frame and the end frames of the lower modular frame are connected, When multiple modular houses are stacked for overseas shipment, the removable corner members used are designed with a thick structure. Because more modular houses need to be stacked for overseas shipment, the corner members must be thickened to make the entire house module more stable and able to withstand greater forces. In this case, the thickness of the corner member seat designed to thicken corner member 5' is greater than the thickness of the corner member seat of the removable corner member described above, thereby improving the corner member's load-bearing capacity, as shown in Figure 17. [Example]

[0060] According to the fourth embodiment, after the modular house is transported to the construction site, the method for installing the modular house on site specifically includes the following steps:

[0061] (1) Remove the four removable corner members on the modular house.

[0062] (2) Lifting the modular house: Before lifting, the movable floor of the modular house is first flipped downward to a horizontal position, and then lifted. The purpose of doing this is as follows: If the modular house is first lifted to the target position and then lowered, on the one hand, lowering it, especially on a very high floor, is time-consuming and laborious due to the weight of the movable floor, and is prone to danger. On the other hand, if the connection of the movable floor is unstable during the lifting process and it flips downward, danger may arise. Considering all aspects, in this embodiment, the movable floor is first lowered to a horizontal position, connected to and fixed with the fixed floor, and then lifted. After the module house is lifted to the target position, the next module house is lifted and installed at a distance from the previously placed module house, with a movable floor panel inverted horizontally between them, and the movable floor panel is connected and fixed to the two adjacent module houses to form a third module house. In addition, beam rods are prefabricated on both ends of the movable floor panel, and the movable floor panel is connected to the columns of the end frames of the adjacent module houses via the beam rods, with auxiliary beam rods connected below the beam rods. When adjacent module houses are stacked one on top of the other, one end of the beam rod is connected to the column of the adjacent module house on the upper level, and one end of the auxiliary beam rod is connected to the column of the adjacent module house on the lower level.

[0063] (3) If the modular house is provided with a movable window, the movable window is rotated to form a bay window or balcony window at the end of the third modular house, and the movable window is fixed.

[0064] (4) If the modular house has an exterior wall and an air conditioner outdoor unit, push out the air conditioner outdoor unit and secure it in place.

[0065] (5) The movable floor boards are connected on-site to the ceiling group of the lower modular house located below them via a connection assembly, and when they are installed on-site, the ceiling connection plate of the connection assembly prefabricated on the upper movable floor boards is simply screwed to the ceiling group of the lower modular house.

[0066] (6) All the modular houses are stacked and fixed, and the air, water, and electrical equipment within each modular house are connected.

[0067] (7) In addition to being stacked vertically, the modular houses can also be arranged horizontally, including left-right and front-to-back. When arranged front-to-back, the end frame columns of each modular house are aligned front to back and connected together via screw connectors to form a double-column structure, which can greatly improve the overall load-bearing stability.

[0068] (8) After the construction of all the modular houses is completed, the roof group and the machinery room module are installed to form the overall structure. Here, the machinery room module includes a modular frame and can meet the container shipping standards. The roof group and the machinery room module are transported separately. [Example]

[0069] 18, in this embodiment, a foldable functional bracket 101 is provided on at least one side of the machinery room module 10. When the machinery room module 10 is transported, the functional bracket 101 is in a stowed state to comply with container transportation standards, and when the machinery room module 10 is installed on site, the functional bracket 101 is in an unfolded state. Here, the functional bracket 101 is hingedly connected to the side of the machinery room module 10 and can be rotated within a 90° range. Preferably, the functional bracket is a solar bracket, and a solar panel 102 is installed on the functional bracket to provide electrical energy to the power-consuming devices in the machinery room module, thereby saving on power consumption costs. [Example]

[0070] As shown in Figures 19 and 20, in this embodiment, a pier foundation 15 is installed between the modular house located on the bottom layer and the foundation embedded member 16. The pier foundation 15 adopts a composite structure, with the upper layer made of the same material as the main body of the modular house, and the lower layer made of the same material as the foundation embedded member 16.

[0071] Specifically, the pier foundation 15 includes a foundation body 151 and a foundation bottom plate 152. The foundation body 151 is connected to the modular house. For example, the modular house in this embodiment is made of stainless steel, so the foundation body is also made of stainless steel and is fastened to the modular house with bolts. The foundation embedding members 16 are installed in the underground concrete. Preferably, carbon steel is used. To effectively connect the stainless steel and carbon steel materials, this embodiment designs the foundation bottom plate 152 as a stainless steel-carbon steel composite plate, thereby forming a two-layer structure. The upper layer is made of stainless steel and is integrally welded to the foundation body 151, and the lower layer is made of carbon steel and is integrally welded to the foundation embedding members 16. In this way, the modular house and the embedded foundation members are connected together using a stainless steel-carbon steel composite plate. On the one hand, the cost of the embedded foundation members is greatly reduced, while the use of stainless steel for the embedded foundation members greatly increases the cost, solving the cost problem of using carbon steel. On the other hand, the stainless steel-carbon steel composite plate is not a structure in which a stainless steel plate and a carbon steel plate are bonded together, but is a composite plate, so there are no gaps between the two layers of plates, there is no corrosion, and the service life is greatly improved.

Any modifications or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application shall be subject to the scope of protection of the claims.
