Description

A modular house overall structure, assembly and on-site installation method Technical Field

[0001] The present invention relates to the technical field of modular buildings, in particular to an overall structure of a modular house, an assembly method and an on-site installation method. Background Art

[0002] Modular homes, also known as container homes or mobile homes, are quick to erect, portable, and reusable. Existing modular homes typically utilize a containerized structure, including end frames, beams, and floor slabs. After being factory-assembled, they are uniformly transported in containers to the construction site for installation and securement. However, the existing modular houses have the following main defects: (1) poor flexibility, the floor slabs, windows, etc. cannot be rotated, and the modular houses can only be assembled one by one, which leads to slow installation speed and high transportation costs; (2) if you want to build a high-rise or super-high-rise building, when several modular houses are stacked up and down, the load-bearing capacity of the beams is weak; (3) when the upper and lower modular houses are hoisted and spliced, the upper modular house is not easy to quickly locate and connect with the lower modular house; (4) the air-conditioning outdoor unit needs to be installed on site, which is time-consuming and labor-intensive; (5) curtains are usually set outside the glass, which are not wind-resistant, easy to damage, difficult to customize, and take up space. If they are set inside the glass, it is easy for the glass to leak and difficult to repair; (6) when the existing modular houses are prefabricated in the factory, they mainly include the production of modules such as wall panels, roofs, floors, doors and windows, and even add electrical wiring, pipeline layout and room Interior decoration, but the space utilization rate in the modular house is still low, resulting in increased transportation costs; and the factory cannot selectively assemble according to the different uses of the modular house; (7) The existing modular house can only be transported individually, and the load-bearing capacity is poor when stacked for transportation. For example, several modular houses need to be stacked for sea transportation, resulting in insufficient strength of the corner parts and poor load-bearing capacity; (8) When the existing modular house is constructed on site, the movable floor is retracted and hoisted, and then flipped open after being hoisted to the target position. However, this method will make the floor time-consuming and labor-intensive when lowering from a high altitude, and the movable floor is prone to loosening during the hoisting process, causing it to flip downward, which is a high risk factor; (9) The existing rooftop machine room is usually designed as a house structure, not in line with the size of a container, with high material transportation costs and slow construction. In addition, the solar panels are usually set separately from the rooftop machine room, occupying a large space.

[0003] In summary, the present invention urgently needs to design a new model of formwork house to solve the above technical problems.

[0023] Component loading: Pack the materials that need to be installed on site and place them in the formwork;

[0024] Movable floor assembly: The movable floor is hinged to the fixed floor to form a flip structure. When the movable floor is retracted, it forms the side panels of the formwork, thus forming a complete modular house.

[0025] Furthermore, when the modular room is a ladder formwork, the ceiling assembly, interior sanitary ware assembly, movable window assembly and movable floor assembly are not carried out. After the formwork is welded, the exterior wall assembly and fire protection layer assembly are carried out. After the fire protection layer is assembled, the electromechanical equipment and pipeline assembly are directly carried out. After the electromechanical equipment and pipeline assembly, the door assembly is carried out. After the door assembly, the components are loaded. After loading, the ceiling assembly is carried out. After that, waterproofing measures are taken and the room is packaged for transportation.

[0026] A method for on-site installation of a modular house according to the present invention comprises the following steps:

[0027] If the corner fittings on the modular house are detachable, remove them;

[0028] Hoist the module room. After the module room is hoisted to the target position, hoist the next module room. The next module room is separated from the already placed module room. The two share a movable floor that has been turned to a horizontal position. The movable floor is connected and fixed to the adjacent two module rooms.

[0029] When the modular room has a movable window, the movable window is rotated out to serve as an end bay window or balcony window of the third modular room, and the movable window is fixed;

[0030] When the modular room has an exterior wall and an air-conditioning outdoor unit, push the air-conditioning outdoor unit out;

[0031] Stack and fix all modular rooms, and connect the electromechanical equipment and pipelines inside each modular room;

[0032] After all the modular rooms are built, the roof assembly and machine room formwork are installed to form the overall structure.

[0033] Furthermore, before hoisting the modular room, the movable floor of the modular room is first turned down to a horizontal position and then hoisted.

[0034] Furthermore, beams are prefabricated at both ends of the movable floor, and the movable floor is connected to the columns of the end frames of adjacent modular houses through the beams; a filler beam is provided below the beam, and when adjacent modular houses are stacked up and down, one end of the beam is connected to the column of the upper modular house, and one end of the filler beam is connected to the column of the lower modular house; when adjacent modular houses are connected front to back, the columns of each modular house are aligned front to back and connected into one by threaded connectors to form a double-column structure.

[0035] Furthermore, when the machine room mold is installed on the roof group, at least one side of the machine room mold is provided with a foldable functional bracket. When the machine room mold is transported, the functional bracket is in a retracted state to meet the container transportation standards; when installed on site, the functional bracket is in an unfolded state.

[0036] Furthermore, a base pier is provided between the module house on the ground floor and the foundation embedded parts. The base pier adopts a composite structure, with the upper layer and the main body of the module house being made of the same material, and the lower layer and the foundation embedded parts being made of the same material.

[0037] Beneficial effects of the present invention:

[0038] (1) By setting up movable floors and movable windows, the modular house can meet the container standards during transportation and be transported together with the modular house. When installed on site, they can be turned over and used as part of another modular house. Compared with assembling modular houses one by one, the installation speed can be greatly improved and the transportation cost can be reduced;

[0039] (2) Adding a supplementary beam on the basis of the original beam can make the beam and the supplementary beam bear the force as a whole, greatly improving the structural strength. It is particularly suitable for high-rise or super high-rise buildings and has a safe bearing capacity.

[0040] (3) By setting pin holes and positioning pins on the flange plate of the column, the upper module room can be quickly installed in place, improving the installation speed, and the positioning pins can be removed after positioning;

[0041] (4) By designing the air conditioner outdoor unit into a structure that can be installed both inside and outside, it can meet the transportation requirements and greatly improve the transportation efficiency. In addition, the air conditioner outdoor unit can be directly pushed out for connection on site, eliminating the need to transport the air conditioner outdoor unit for on-site installation, greatly simplifying the assembly steps and saving time and effort.

[0042] (5) By arranging curtains in the cavity of the insulating glass, there is no need to occupy the space outside the glass, and the curtains can be installed at the same time as the glass during installation, without the need for additional operations, and the installation is convenient; by arranging inspection ports and inspection sealing plates, the curtains can be inspected while ensuring the insulation and sealing of the glass; and combined with the inflatable core, it can prevent air leakage and condensation in the glass cavity, which is particularly suitable for situations where the inner cavity of the insulating glass is large;

[0043] (6) When the modular house is prefabricated in the factory, components of other modular houses can be placed inside it, such as movable windows and movable floors, making full use of the internal space of the modular house, and the materials that need to be installed on site can be packed and placed in the formwork. This is equivalent to transporting two modular houses in the prior art, while the present invention only needs to transport one modular house to achieve the construction of two modular houses; furthermore, the present invention can perform different assembly of side molds, ladder molds, etc., with strong flexibility and a wide range of applications;

[0044] (7) By setting up reinforced corner pieces, it is particularly suitable for overseas transportation, greatly improving the stability of the house formwork when stacking multiple layers, and is not easily deformed by pressure;

[0045] (8) During on-site construction, by lowering the movable floor to a horizontal position and connecting it with the fixed floor before hoisting, there is no need to lower it again during high-altitude operations, and there is no need to worry about whether the movable floor will loosen and turn over during the hoisting process, which greatly improves the safety factor and saves time and effort during on-site installation;

[0046] (9) By designing the rooftop computer room template to a size that meets the container transportation standards and providing a foldable functional bracket on the computer room template, it can be retracted during transportation, so that the functional bracket can be transported by sea and land along with the computer room template, thereby reducing transportation costs; when installed on site, it can be placed directly on the roof without the need for additional construction like a traditional computer room, greatly reducing the amount of on-site construction, and the functional bracket can be unfolded to lay solar panels or hang clothes, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0072] Example 1

[0073] As shown in Figure 1: a modular house overall structure, including a formwork 1 and a movable floor 2; the formwork 1 includes two end frames 11, a beam 12 arranged between the end frames, and a fixed floor 13 arranged at the bottom; the movable floor 2 is hinged to the fixed floor 13, so that the movable floor 2 can be flipped along the fixed floor 13.

[0074] In this embodiment, a beam 12 is provided on one side between the two end frames 11, while no beam is provided on the side where the movable floor is provided. For example, a beam 12 is provided on the upper portion of one side of the two end frames, and the beam is provided against the inner side of the end frames to facilitate the installation of an exterior wall. A plurality of spaced inner connecting rods 14 are provided between the beam 12 and the fixed floor 13. Diagonal braces 15 are provided between the two end frames 11 and the upper beam 12. The beam is prefabricated directly on one side of the fixed floor 13 at the bottom, and the other side is connected to the movable floor 2 by a hinge, allowing the movable floor 2 to flip 90 degrees along the fixed floor. By flipping upward, it can serve as the side wall of the formwork 1; by lowering it to a horizontal position, it can serve as the floor of another space.

[0075] As shown in Figure 2, in this embodiment, the end frame 11 comprises two columns 111 and an upper crossbeam 112 and a lower crossbeam 113 connecting the columns. One column has a rectangular cross-section, while the other has a square or quasi-square cross-section. Flange plates 114 are provided on both the upper and lower surfaces of the columns. These flange plates cover the surfaces of the columns and enable threaded connections between the columns of the upper and lower formwork. For larger flange plates, a hole can be drilled in the center. For example, the threaded holes on the flange plate can be arranged around the outer edge of the flange plate, with a hole drilled in the center. This allows the cut plate to be used for other purposes, saving material. Lifting holes 115 are provided on both sides of the top of the upper crossbeam 112 to facilitate hoisting of the modular house. The corner fittings in this embodiment are preferably designed as detachable corner fittings 5 ​​for use during transportation. However, removing the corner fittings during on-site construction prevents hoisting. Therefore, by providing lifting holes 115 in the upper crossbeam, on-site hoisting of the modular house is possible. Preferably, the structure of the lifting holes 115 is the same as that of the lifting holes on the corner fittings. Connecting sockets 116 are prefabricated on the side and end faces of the column to facilitate threaded connection with other components. In this embodiment, the end frame 11 is a prefabricated structure, meaning that the column, crossbeam, flange plate, and all connecting sockets are prefabricated in the factory to form the end frame. In addition, a fireproof layer 117 is provided on the column and crossbeam of the end frame.

[0076] As shown in Figures 3 and 4, the column flanges are also equipped with pin holes 118. When connecting the upper and lower modular rooms, the positioning pin 3 is connected to the pin hole 118 of the lower modular room. When the upper modular room is hoisted above the lower modular room, the pin hole on the lower end of the column of the upper modular room is inserted through the positioning pin of the lower modular room to achieve the positioning of the upper and lower modular rooms. After the upper modular room is in place, the positioning pin is removed, and the columns of the upper and lower modular rooms are then screwed together using flange plates 114. Furthermore, when the lower modular room is positioned with the ground, the bottom surface of the column of the lower modular room is also positioned with the ground using positioning pins 119 and pin holes 118, respectively. This positioning method enables rapid positioning and installation of the upper and lower modular rooms.

[0077] The modular house of this embodiment can be used as a residential building, stairwell module, or computer room module. For example, when used as a stairwell module, stairs and elevators can be installed within the module frame. When used as a computer room module, electrical equipment and other equipment can be installed within the module frame and placed on the roof. Regardless of the building type, the modular house can meet container transportation standards for both land and sea transport. On-site installation is similar to building blocks, making it easy to transport and install, saving time and effort.

[0078] As shown in Figure 5, in this embodiment, a ceiling assembly 3 is installed on top of the formwork 1, and a suspended ceiling assembly 4 is installed below the ceiling assembly 3. Mechanical and electrical equipment and pipelines, such as plumbing, electricity, and other related equipment, are placed between the ceiling assembly 3 and the suspended ceiling assembly 4, and are transported with the modular house. The suspended ceiling assembly 4 includes a suspended ceiling panel 41, a suspended ceiling gusset 42, and a suspended ceiling frame 43. The suspended ceiling frame 43 can be used to house equipment such as a fresh air blower and air conditioner. The ceiling assembly 3 is installed above the suspended ceiling frame.

[0079] As shown in Figures 6-8, in this embodiment, the fixed floor slab 13 at the bottom of the upper formwork and the ceiling assembly 3 of the lower formwork below it can be prefabricated and connected in the factory for integrated transportation or installed on-site. The movable floor slab is connected to the ceiling assembly of the lower formwork below it via a connecting assembly 31 for on-site installation. Specifically, the ceiling assembly comprises multiple interconnected panels, with the long edges of adjacent panels designed as a clevis. The clevis 32 is snapped together, and the gaps are filled with fireproof sealing material. C-shaped frames 33 are provided on the short edges of each panel. The connecting assembly 31 includes a ceiling base 311, a ceiling connecting base 312, a ceiling rod 313, and a ceiling connecting plate 314. The ceiling base 311 is connected to the movable floor 2 and can be prefabricated on the movable floor in advance. The ceiling connecting base 312 is threadedly connected to the ceiling base 311. The upper portion of the ceiling rod 313 is connected to the ceiling connecting base 312, and the lower end of the ceiling rod is connected to the ceiling connecting plate 314. The ceiling connecting plate 314 is threadedly connected to the C-shaped frame 33 of the ceiling assembly of the lower room formwork. Because the ceiling assembly below the fixed floor 13 and the ceiling assembly below the movable floor 2 are arranged adjacent to each other, the ceiling connecting plate 314 can extend to the C-shaped frame of the ceiling assembly below the fixed floor, allowing the ceiling connecting plate 314 to be threadedly connected to the two adjacent ceiling assemblies at the same time, thereby greatly improving installation speed.

[0080] It is understandable that the ceiling connection plate of this embodiment can also be designed as a ceiling hook, which can directly hook the C-shaped frame through the ceiling hook without using a threaded connection. However, although this method is faster to install, the connection stability is worse than that of a threaded connection.

[0081] As shown in Figure 9, in this embodiment, beams 21 are prefabricated at both ends of the movable floor 2. Below the beams 21, there are filler beams 22. When multiple modular houses are stacked and installed, for example, the movable floor of the upper formwork is lowered to a horizontal position. One end of the beam 21 is threadedly connected to the column 111 of the end frame of that formwork layer through a connector, while the other end of the beam 21 is connected to the column of the adjacent formwork layer. The filler beam 22 is installed on-site, with both ends of the filler beam 22 threadedly connected to the column 111 of the lower adjacent formwork layer. The filler beam 22 is also secured to the beam 21 with bolts. Nuts are embedded in the beams 21, and the bolts pass through the filler beams 22 and into the beams, connecting to the pre-embedded nuts, forming a single unit that meets the overall load-bearing requirements. This embodiment, by adding filler beams to the existing beams, allows the beams and filler beams to bear loads as a whole, significantly improving structural strength. This is particularly suitable for high-rise or super-high-rise buildings.

[0082] In this embodiment, support beams are prefabricated at the lower parts of the movable floor 2 and the fixed floor 13. When the movable floor is turned over to be level with the fixed floor, the support beams of the two are connected and fixed.

[0083] As shown in Figure 10, in this embodiment, after the movable floor 2 is lowered, it is connected and fixed to the fixed floor 13. Specifically, floor connection bases 21 are provided on the bottom surfaces of the movable floor 2 and the fixed floor 13, respectively. A connecting plate 22 is shared between the two floor connection bases. One bolt passes through the connecting plate to connect to the floor connection base of the movable floor, and another bolt passes through the connecting plate to connect to the floor connection base of the fixed floor, thereby securing the two. A rock wool layer 23 is filled in the gap between the movable floor and the fixed floor.

[0084] As shown in Figure 11, in this embodiment, some modular houses also include a movable window 6, such as a residential house. The movable window 6 is connected to the column 111 of the end frame 11 via a window hinge 61, with one end of the window hinge 61 connected to the inner side of the column 111. When the movable window 6 is stored in the formwork during transportation, the modular house can be transported in accordance with container standards. During on-site installation, it is flipped out and, together with the movable floor 2, becomes part of another space. The movable window 6 can be a bay window or a balcony window, for example. For example, a bay window can be hinged on one end frame, and a balcony window can be hinged on the other end frame. During on-site installation, the movable window 6 is flipped out and serves as the end window at each end of another space, forming a new modular house structure together with the movable floor 2.

[0085] In this embodiment, at least one end frame 11 is provided with an outer wall 7. For example, both end frames are provided with an outer wall 7, or one end frame is provided with an outer wall and the other end frame is provided with a balcony window. Windows can also be provided on the outer wall.

[0086] During factory prefabrication of the modular house of this embodiment, plumbing and electrical piping, such as water supply and drainage pipes, oil fume risers, sewage pipes, and fresh air ducts, are prefabricated within the formwork. Bathroom hardware and sanitary ware, such as sinks, toilets, and showers, are also prefabricated. In other words, the present invention prefabricates all hardware. Upon transport to the site for installation, only the plumbing and electrical piping between the upper and lower floors need to be connected. For modular houses requiring interior walls, these walls are also prefabricated within the formwork at the factory.

[0087] In this embodiment, the fixed floor, movable floor, and ceiling assembly all utilize metal core panels, preferably made of stainless steel or aluminum. The core panels comprise upper and lower panels, and a sandwich layer sandwiched between them. The sandwich layer comprises an array of hollow tubes brazed to the panels. The tubes are spaced apart, with insulation layers positioned in the gaps between adjacent tubes. It is understood that the sandwich layer of the present invention may also utilize other spaced-apart structures, such as a corrugated core.

[0088] The specific method of assembling the modular house in the factory of this embodiment includes the following steps:

[0089] Formwork welding: Assemble the end frame 11, fixed floor slab 13, beam body 12, and inner connecting rod 14 to form a formwork structure; wherein, the various connection seats on the end frame 11 and the connection seats, beams, and support beams on the fixed floor slab 13 are all prefabricated on the main body in advance, and only need to be welded on site. In addition, since the fixed floor slab and the movable floor slab are core plate structures, when cutting the core plate, it is necessary to cut the front and back sides, because the core plate is not a single-layer plate, and there is a sandwich layer in the middle, which has a certain thickness. If you cut directly from the upper panel to the lower panel, it is easy to cut inaccurately. Therefore, after cutting the front panel, turn it over to the back to cut the back panel. When welding the core plates to form the floor slab, it is also necessary to weld the front and back sides.

[0090] External wall assembly: For modular houses that require external walls, external wall assembly is performed, such as installing the external wall 7 on the outside of the end frame and installing the side external wall on the side of the formwork beam 12.

[0091] Fireproof layer assembly: Install fireproof layer 117 on the columns and beams of the front end frame and the rear end frame to wrap the columns and beams to improve fire resistance.

[0092] Assembly of suspended ceiling group: For modular rooms that require suspended ceiling, assemble suspended ceiling group 4 on the top of the formwork.

[0093] Mechanical and electrical equipment assembly: Mechanical and electrical equipment and pipelines are assembled inside the formwork. The mechanical and electrical equipment and pipelines can be selectively assembled and interlaced with the inner wall 9.

[0094] Interior assembly: For modular houses that require interior decoration, bathroom hardware sets and doors are assembled inside the mold frame.

[0095] Assembly of movable window group: For modular houses that require movable windows 6, movable windows are installed on the inner side of the end of the formwork, which can be rotated out or retracted along the end frame.

[0096] Ceiling assembly: Install ceiling assembly 3 above suspended ceiling assembly 4.

[0097] Component loading: The materials that need to be installed on site are packed together and placed in the formwork.

[0098] Movable floor assembly: The movable floor 2 is hinged to the fixed floor 13 to form a flip structure. When the movable floor 2 is retracted, it forms the side panel of the formwork 1, thereby forming a complete modular house.

[0099] Among them, when the modular room is a staircase room module, it is not necessary to assemble the suspended ceiling, interior sanitary ware, movable windows and movable floor slabs. After the formwork is welded, the exterior wall and fire protection layer can be assembled. After the fire protection layer is assembled, the electromechanical equipment and pipelines can be assembled directly. After the electromechanical equipment is assembled, the door can be assembled. After the door is assembled, the components are loaded. After loading, the ceiling can be assembled. After that, waterproof measures are taken and the equipment is packaged for transportation.

[0100] In this embodiment, when the modular house is assembled in the factory, it includes a structural section, an interior decoration section, a loading section, a movable plate section, and a packaging and shipping section along the direction of the modular house assembly. The production lines of each section jointly transfer the modular house from the first station to the last station through a traction conveyor system, thereby forming the final modular house structure. For example, the structural section includes at least three stations, which respectively assemble the end frame, fixed floor slab, beam body, etc. to form a preliminary formwork structure, focusing on ensuring dimensional accuracy. The interior decoration section includes at least six stations, which are used for the internal decoration of the formwork, mainly including fireproof layer, ceiling, wall, door, and Fengshui and electricity; all materials weighing more than 15kg are matched with special lifting equipment for lifting, and each module is moved to the appropriate position for positioning and installation. The loading section includes a loading station, which centrally packages the materials that need to be installed on site and transports them to the installation site along with the house formwork, such as interior wall doors, cabinets, and beam rods that need to be installed on site. The movable floor section includes a movable floor station, which welds the movable floor slab to the fixed floor slab with hinges and then uses a semi-gantry crane to flip the slab 90° and secure it. The packaging and shipping section includes a film covering station, where the finished modular houses are completely wrapped with scraper cloth and tied with nylon ropes, and a shipping station, where the finished modular houses are hoisted onto trucks for shipment to the installation site or storage area.

[0101] Example 2

[0102] As shown in Figures 12 and 13: Based on Example 1, a movable part for connecting the air-conditioning outdoor unit 71 is provided in the outer wall cavity of this embodiment, and the air-conditioning outdoor unit 71 can be selectively built into the outer wall cavity or extended along the outer wall cavity; when the module room is transported, the air-conditioning outdoor unit 71 is arranged in the outer wall cavity; when installed on site, the air-conditioning outdoor unit 71 extends along the outer wall cavity.

[0103] Among them, the movable part is a detachable structure or a push-pull structure. When it is a detachable structure, it can be fixed and disassembled by a screw assembly 74. For example: an external unit bracket 72 is provided at the bottom of the air-conditioning outdoor unit 71, and the external unit bracket 72 is threadedly fixed to the screw assembly in the outer wall cavity. When a part of the air-conditioning outdoor unit is pushed out of the outer wall cavity, the air-conditioning outdoor unit is removed and pushed into the air-conditioning grille 73 connected to the outside of the outer wall. The air-conditioning grille 73 is installed on site. The inner part of the external unit bracket 72 of the air-conditioning outdoor unit is connected and fixed to the screw assembly 74, and the outer part is fixed to the air-conditioning grille through a connector. When it is a push-pull structure, it can be designed as a slide rail structure, that is, two slide rails are provided in the outer wall cavity, and the slide rails are connected to the push-pull plate. The external unit bracket of the air-conditioning outdoor unit is fixed to the push-pull plate by bolts. By manually pushing out or retracting the push-pull part, the internal and external states of the air-conditioning outdoor unit can be realized.

[0104] Example 3

[0105] As shown in Figure 14: Based on Example 1, hollow glass 8 is provided on the exterior wall and / or the movable window, a curtain 81 is provided in the cavity of the hollow glass 8, an inspection port is provided on the hollow glass, an inspection sealing plate 82 is provided at the inspection port, and an inflatable core 83 connected to the hollow glass cavity is provided between the window frame and the hollow glass.

[0106] Specifically, two inflatable cores 83 connected to the hollow glass cavity are provided between the window frame and the gap between the hollow glass. The two inflatable cores are arranged one above the other, one for inflation and the other for exhaust, so as to form an inflation and exhaust channel between the hollow glass cavity. The inflatable core 83 is preferably a valve core, such as a metal valve core used in cars or motorcycles, which has a small outer diameter, usually 3 to 6 mm, and does not take up too much space. The two inflatable cores can be selected for inflation or exhaust according to the density of the inert gas filled. For example, in this embodiment, argon is preferably filled. Since the density of argon is greater than that of air, the inflatable core located at the bottom is selected for inflation, and the inflatable core located at the top is selected for exhaust.

[0107] The curtain 81 is provided within the cavity of the insulating glass 8, eliminating the need to occupy the space outside the glass. Conventional insulating glass, due to its small internal cavity, can be treated with a molecular sieve; however, the curtain in this embodiment results in a larger cavity, making it difficult for the molecular sieve to handle air leakage. Therefore, the provision of two inflatable cores effectively solves this problem.

[0108] In order to be able to inspect and maintain the electrical components at the wave curtain or the curtain itself, this embodiment also provides an inspection port on the upper part of the insulating glass. The inspection port is located between the inner glass of the insulating glass 8 (the side facing the interior) and the window frame. The inspection port is provided with an inspection seal 82. The inspection seal 82 is designed as a thermal insulation structure, including thermal insulation cotton and an outer panel arranged around the outer periphery of the thermal insulation cotton. The outer panel is provided with a rim that can wrap the thermal insulation cotton. The lower end of the outer panel is sealed to the inner glass of the insulating glass. An L-shaped piece 84 is provided on the inside. One end of the L-shaped piece 84 is glued to the rim 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 sealed to the window frame by sealant and a sealing member. The inflatable core located at the top is connected to the inspection seal. The inflatable core 83 passes through the thermal insulation layer of the inspection seal 82 and is connected to the cavity of the insulating glass 8. It is also welded and fixed to the outer panel to prevent shaking during inflation and degassing. When the curtain 81 needs to be repaired, the colloid can be cut off and the inspection sealing plate 82 can be disassembled for repair. After the repair, the inspection sealing plate is further sealed with colloid and re-inflated and exhausted through the upper and lower inflatable cores 83.

[0109] Example 4

[0110] When the modular house is packed for transportation, the transportation methods include:

[0111] (1) Removable corner fittings 5 ​​are installed at the four corners of the front end frame and the rear end frame, specifically at the upper front end surface of the column. The removable corner fittings 5 ​​include a corner fitting seat 51 and a corner fitting body 52. ​​The structure of the corner fitting body 52 is the same as that of the existing standard corner fittings of containers. The corner fitting seat 51 is screwed to the column 111, and the corner fitting body 52 extends horizontally along the corner fitting seat 51, which meets the container transportation standards, as shown in Figure 15.

[0112] (2) When the modular house has a movable window, rotate the movable window into the mold frame;

[0113] (3) When the modular room has an exterior wall and an air-conditioning outdoor unit, retract the air-conditioning outdoor unit into the cavity of the exterior wall;

[0114] (4) The movable floor is folded to the side of the formwork to form a structure that meets the container transportation standards for transportation. The transportation method is shown in Figure 16.

[0115] It is understood that when several modular houses need to be stacked for transportation, the fixed floor slab at the bottom of the upper formwork is connected to the ceiling assembly of the lower formwork located therebelow; and the end frame of the upper formwork is connected to the end frame of the lower formwork;

[0116] When stacking multiple modular houses for overseas transport, the detachable corner fittings are designed with a thickened structure. Since more modular houses need to be stacked for overseas transport, the corner fittings need to be thickened to make the entire house form more stable and able to withstand greater forces. Therefore, the thickness of the corner fitting seat of the thickened corner fitting 5' is greater than that of the detachable corner fitting seat, thereby increasing the corner fitting's load-bearing capacity, as shown in Figure 17.

[0117] Example 5

[0118] On the basis of Example 4, after the modular house is transported to the construction site, the on-site installation method of the modular house specifically includes the following steps:

[0119] (1) Remove the four detachable corner pieces on the modular house.

[0120] (2) Before hoisting the modular room, the movable floor of the modular room is first turned down to a horizontal position before hoisting. The purpose of this is that if the modular room is hoisted to the target position before lowering, on the one hand, especially when lowering it to a very high floor, the movable floor is very heavy, which is not only time-consuming and labor-intensive but also prone to danger. On the other hand, if the movable floor connection is unstable and turns downward during the hoisting process, it will also be dangerous. Taking all factors into consideration, this embodiment lowers the movable floor to a horizontal position and connects it to the fixed floor before hoisting. After the module room is hoisted to the target position, the next module room is hoisted, and the next module room is separated from the placed module room, and the two share a movable floor that has been flipped to a horizontal position, and the movable floor is connected and fixed to the two adjacent module rooms to form a third module room; in addition, beams are prefabricated at both ends of the movable floor, and the movable floor is connected to the columns of the end frames of the adjacent module rooms through the beams; supplementary beams are connected below the beams, and when adjacent module rooms are stacked up and down, one end of the beam is connected to the column of the upper adjacent module room, and one end of the supplementary beam is connected to the column of the lower adjacent module room.

[0121] (3) When the modular room has a movable window, the movable window is rotated out to serve as an end bay window or balcony window of the third modular room, and the movable window is fixed.

[0122] (4) When the modular room has an exterior wall and an air-conditioning outdoor unit, push out and secure the air-conditioning outdoor unit.

[0123] (5) The movable floor and the ceiling assembly of the lower modular room below it are installed on-site through connecting components. During on-site installation, it is only necessary to thread the ceiling connecting plate of the connecting component prefabricated on the upper movable floor and the ceiling assembly of the lower modular room.

[0124] (6) All modular houses are stacked and fixed, and the air, water and electricity inside each modular house are connected.

[0125] (7) In addition to being stacked up and down, the modular houses can also be placed horizontally, including left-right and front-to-back arrangements. When arranged front-to-back, the end frame columns of each modular house are aligned front-to-back and connected together through threaded connectors to form a double-column structure, which can greatly improve the overall stress stability.

[0126] (8) After all modular rooms are built, the roof assembly and the machine room formwork are installed to form the overall structure. The machine room formwork includes a formwork frame that can meet container transportation standards. The roof assembly and the machine room formwork are transported separately.

[0127] Example 6

[0128] As shown in Figure 18, in this embodiment, a foldable functional bracket 101 is provided on at least one side of the machine room module 10. When transporting the machine room module 10, the functional bracket 101 is retracted to comply with container transportation standards; during on-site installation, the functional bracket 101 is extended. The functional bracket 101 is hinged to the side of the machine room module 10 and can be rotated within a 90° range. Preferably, the functional bracket serves as a solar panel, with solar panels 102 installed on the functional bracket to provide power to the electrical equipment within the machine room module, thereby saving electricity costs.

[0129] Example 7

[0130] As shown in Figures 19 and 20: In this embodiment, a base pier 15 is provided between the module house on the bottom floor and the foundation embedded parts 16. The base pier 15 adopts a composite structure, with the upper layer and the main body of the module house being made of the same material, and the lower layer and the foundation embedded parts 16 being made of the same material.

[0131] Specifically, the foundation pier 15 comprises a pier body 151 and a pier base plate 152. The pier body 151 is connected to the modular housing. For example, if the modular housing in this embodiment is made of stainless steel, then the pier body is also made of stainless steel. The pier body and modular housing are secured together by bolts. The foundation embedded components 16 are located within the underground concrete and are preferably made of carbon steel. To effectively connect the stainless steel and carbon steel components, the pier base plate 152 in this embodiment is designed as a stainless steel-carbon steel composite plate, forming a two-layer structure. The upper layer is made of stainless steel and welded to the pier body 151, while the lower layer is made of carbon steel and welded to the foundation embedded components 16. In this way, the modular house and the foundation embedded parts are connected into one by the stainless steel-carbon steel composite plate. On the one hand, the cost of the foundation embedded parts is greatly reduced, because if the foundation embedded parts are made of stainless steel, the cost will be greatly increased, and the use of carbon steel will solve the cost problem; on the other hand, the stainless steel-carbon steel composite plate is not a structure in which stainless steel plates and carbon steel plates are bonded together, but a composite plate. There is no gap between the two layers of plates, and there will be no corrosion, which greatly improves the service life.

[0132] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
