Description

Technical Field

[0001] The present invention relates to the technical field of temporary buildings, and in particular to a double-layer foldable house and an integrated building method. Background Art

[0002] As a mobile, reusable temporary or permanent building structure, foldable houses are gaining increasing attention with the development of society and the increasing demand for flexible living spaces. While traditional foldable houses address the issues of transportability and construction speed to a certain extent, they still have many shortcomings.

[0003] The folding and unfolding ratio of existing folding houses is relatively low, and the volume after folding is large, which takes up transportation space. In addition, the structural design of some folding houses is complex, and the folding and building process requires a lot of manual operation, which is inefficient, and the overall stability is poor when used in multiple layers. In the field of construction, the construction method of folding houses also has limitations. In some existing technologies, the assembly of houses relies on complex mechanical structures or a large number of bolt connections, which is not only time-consuming and labor-intensive, but may also lead to structural instability due to improper operation. In recent years, although folding houses based on flexible enclosures or self-lifting frames have emerged, and the construction efficiency has been improved through integrated construction methods, it is still difficult to achieve fast, efficient and stable construction during the folding and unfolding of double-layer or multi-layer houses.

[0004] Therefore, the present invention aims to develop a double-layer foldable house with a high folding / expansion ratio and an integrated construction method thereof, which can effectively reduce the volume after folding and improve the construction efficiency and structural stability.

[0046] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0047] To address the aforementioned technical issues, the present invention provides a double-layer foldable house with a high expansion ratio, easy deployment, high maneuverability, and a relatively stable structure. This allows for rapid, large-scale deployment, transportation, and installation in a variety of environments. Furthermore, the house's entirety is folded using hydraulic rods, eliminating the need for mechanical assistance. When collapsed, it can store a complete set of supporting equipment, reducing transportation burdens and costs.

[0048] In a specific embodiment, Figure 1-Figure 7As shown, the double-layer foldable house provided by the present invention includes a roof assembly and a frame assembly 4. The roof assembly includes a horizontally retractable bottom plate assembly, a top plate assembly arranged parallel to the bottom plate assembly, a telescopic rod installed between the bottom plate assembly and the top plate assembly, a hidden panel foldably arranged between the bottom plate assembly and the top plate assembly, a lower side wall assembly foldably arranged between the bottom plate assembly and the hidden panel, and an upper side wall assembly foldably arranged between the top plate assembly and the hidden panel, wherein a door is provided on the lower side wall assembly; the telescopic rod is vertically arranged between the bottom plate assembly and the top plate assembly to drive the top plate assembly and the bottom plate assembly to move closer or further away; the telescopic rod can be in the form of a hydraulic rod, a pneumatic rod, or an electric telescopic rod. The frame assembly 4 includes a frame bottom plate, a frame top plate arranged parallel to the frame bottom plate, and a side frame connecting the frame bottom plate and the frame top plate. The side frames are detachably connected to the bottom plate assembly and the top plate assembly respectively. After the side wall panels of the house are unfolded, they are connected to the frame by groove bolts. The assembled frame can strengthen the overall structure of the house.

[0049] In this way, the double-layer foldable house has a foldable function by providing a horizontally retractable bottom plate assembly and a top plate assembly, as well as foldable upper and lower side wall assemblies and a foldable hidden plate, which is convenient for transportation and construction; the setting of the telescopic rod can conveniently adjust the distance between the top plate assembly and the bottom plate assembly to realize the expansion and folding of the house; the detachable connection method of the frame assembly 4 is convenient for providing additional support and protection after the house is expanded, thereby enhancing the stability and integrity of the house.

[0050] In some embodiments, the base plate assembly includes a base plate 11, a retractable base plate 10, and a bottom telescopic rod 30. The base plate 11 includes at least two detachable sub-base plate bodies, each of which, when combined, encloses a first accommodating space, within which the retractable base plate 10 is disposed. The bottom telescopic rod 30 is installed between any two of the sub-base plate bodies to drive the base plate assembly to expand or retract. The sub-base plate body on which the bottom telescopic rod 30 is installed has a built-in groove for accommodating the bottom telescopic rod 30, which can be a hydraulic rod or an electric telescopic rod.

[0051] The combined design of the base plate 11 and the retractable base plate 10 allows the base plate assembly to be horizontally retracted and extended. The driving action of the bottom telescopic rod 30 precisely controls the expansion and contraction of the base plate assembly, increasing the flexibility and convenience of house construction. In the expanded state, the base area of the house is expanded, providing a more spacious living space; in the folded state, the house's footprint is reduced, making it easier to transport and store.

[0052] In some embodiments, the top panel assembly includes a top panel 2, a retractable top panel 1 and a top telescopic rod 3; wherein, the top panel 2 includes at least two detachable sub-top panel bodies, and each of the sub-top panel bodies encloses a second accommodating space when combined; the retractable top panel 1 is arranged in the second accommodating space, and the top telescopic rod 3 is installed between any two of the sub-top panel bodies to drive the top panel assembly to expand or contract.

[0053] Similar to the bottom panel assembly, the design of the top panel 2 and retractable top panel 1, along with the driving action of the top telescopic rod 3, enables the top panel assembly to be retracted and extended horizontally. When unfolded, the roof area of the house is expanded to match the bottom panel assembly, providing a larger living space. When folded, the overall height and volume of the house are reduced, making it easier to transport and store.

[0054] Furthermore, the upper side wall assembly and the lower side wall assembly are connected via a double-layer hinge, allowing them to fold up and down. During deployment, the lower side wall assembly flips downward to a vertical position, while the upper side wall assembly flips upward to a vertical position. This double-layer hinge connection allows the upper and lower side wall assemblies to tightly fold up and down, reducing the volume of the house in its folded state. During deployment, the lower side wall assembly flips downward and the upper side wall assembly flips upward to a vertical position, quickly forming the house's side wall structure. This makes the construction process simple and efficient, while also ensuring the stability and sealing of the side walls.

[0055] Specifically, the upper side wall assembly includes a plurality of foldable and connected upper side panels, and adjacent upper side panels are locked or released by locks; and / or, the lower side wall assembly includes a plurality of foldable and connected lower side panels, and adjacent lower side panels are locked or released by locks. Each upper side panel includes a side wall panel without a hidden middle panel and a side wall panel with a hidden middle panel, and each lower side panel includes a side wall panel without a hidden middle panel and a side wall panel with a hidden middle panel. The side wall panels of the house are connected by two hinge structures, and all side wall panels have built-in grooves for placing self-locking buckles. Each side wall panel contains six self-locking buckle grooves. The side wall panels of the house with hidden middle panels are connected to the hidden panels by a hinge structure, and the connection is controlled by buckles. When the house is unfolded, the hidden panels are lowered to form the second floor of the foldable house.

[0056] The design of multiple foldable, connected upper and lower side panels further reduces the size of the side wall assembly when folded. The locking mechanism locks adjacent side panels together after the side wall assembly is unfolded, ensuring the integrity and stability of the side wall and preventing it from shaking or shifting during use, thereby improving the safety and reliability of the building.

[0057] Furthermore, an umbrella-shaped support plate 23 is installed on the lower surface of the hidden panel 22, and a support rod 26 is installed between the umbrella-shaped support plate 23 and the bottom plate assembly. The umbrella-shaped support plate 23 is connected to the hidden panel 22 and the side wall panel by grooves and bolts, and the umbrella-shaped support plate 23 is connected to the support rod 26 by groove bolts and has a self-locking structure. The umbrella-shaped support plate 23 part provides higher strength for the second floor of the foldable house. The setting of the umbrella-shaped support 23 and the support rod 26 provides an additional support structure for the hidden panel 22. After the house is unfolded, the hidden panel 22 is used as the second floor floor and can withstand a certain weight to ensure the safety and stability of the second floor space. At the same time, this support structure can be easily disassembled or stored when folded, without affecting the folding and transportation of the house.

[0058] In some embodiments, a telescopic ladder 17 is installed between the base and top panels. When the base is secured, the top panel rises as the telescopic rods extend, and the ladder simultaneously unfolds. This arrangement facilitates movement between upper and lower levels of the building. When the building is folded, the ladder 17 retracts vertically, minimizing space. When the building is unfolded, the ladder extends, providing convenient access and enhancing the building's usability.

[0059] Furthermore, the hidden plate 22 is provided with an escape notch, through which the telescopic ladder 17 passes through the hidden plate 22. The creation of the escape notch allows the telescopic ladder 17 to pass smoothly through the hidden plate 22, achieving connectivity between the upper and lower floors. This ensures the normal use of the telescopic ladder 17 while not affecting the integrity and functionality of the hidden plate 22 as the second floor, thereby making the spatial layout of the house more reasonable.

[0060] A storage box 12 is also provided on the base assembly, providing additional storage space for the house. During the construction of the house, tools, furniture, and other items can be stored in the storage box 12 for easy organization and storage. During the use of the house, some commonly used items can also be placed in the storage box 12, thereby improving the space utilization rate and living convenience of the house.

[0061] The present invention also provides an integrated construction method for the double-layer foldable house described above, comprising the following steps:

[0062] S1: Fix the lower end of the connected telescopic rod to the upper side of the bottom plate, and fix the upper end of the telescopic rod to the lower side of the top plate 2; by fixing the telescopic rod to the bottom plate and the top plate 2, a stable support structure is provided for the subsequent unfolding and folding of the house, ensuring that the telescopic rod can accurately drive the top plate assembly and the bottom plate assembly closer or farther away.

[0063] S2: The base plate is fixed to the ground. The telescopic rods between the sub-base plates extend, driving the retractable base plates between the sub-base plates to unfold, securing the base plates and leveling them. Fixing the base plates to the ground ensures the stability of the house. The extension of the telescopic rods causes the retractable base plates to unfold, expanding the floor area of the house. Leveling the base plates provides a smooth foundation for subsequent construction, ensuring the stability and safety of the overall structure.

[0064] S3: The roof is fixed to the ground. The top telescopic rods 3 between the sub-roof panels extend to expand the retractable roof panels 1 between the sub-roof panels, securing the roof and leveling it. Similar to the operations for the bottom panel, the securing and deployment of the roof expands the roof area of the house. Leveling the roof parallel to the bottom panel ensures the regularity and comfort of the interior space.

[0065] S4: unfold the folded upper side wall assembly and the lower side wall assembly outward, fix the upper end of each upper side panel to the top panel, and fix the lower end of each lower side panel to the bottom panel; by unfolding the upper and lower side wall assemblies and fixing them to the top panel and the bottom panel, the side wall structure of the house is preliminarily formed, providing a closed living space for the house and enhancing the integrity and sealing of the house.

[0066] S5: Expand and secure the telescopic rod between the bottom plate and the top plate; the lower side plates that are not fully expanded are expanded downward as the telescopic rod extends, and the upper side plates that are not fully expanded are expanded upward, and the expanded upper and lower side plates are locked with locks to maintain the expanded state of the side plates; the expansion of the telescopic rod further expands the height space of the house, and the complete expansion and locking of the lower and upper side plates ensures the integrity and stability of the side walls, allowing the house to withstand certain external forces and improving the safety of the house.

[0067] S6: Open the hidden panel buckle and lower the hidden panel to form the second floor of the double-layer foldable house. Lowering the hidden panel to form the second floor increases the usable space of the house, realizes the double-layer function of the house, and improves space utilization.

[0068] S7: Assemble the umbrella-shaped support plate and the support rod, and install and fix the umbrella-shaped support plate under the hidden plate; the installation of the umbrella-shaped support plate and the support rod provides support for the hidden plate, ensures the bearing capacity of the second-floor floor, and ensures the safety of people when they are on the second floor.

[0069] S8: Take out the furniture from the storage box and place it in place; taking out the furniture from the storage box and placing it in place makes the house have basic living functions and improves the convenience and comfort of the house.

[0070] S9: Install and secure the external frame to the unfolded double-layer foldable house. The external frame further enhances the stability and integrity of the house, while also providing additional protection and decorative features, improving both its appearance and practicality.

[0071] In the above-mentioned specific embodiment, the double-layer foldable house provided by the present invention is unfolded using hydraulic movable rods and folding side panels, and is filled with polyurethane internally, reducing the weight of the overall structure. This allows for easy deployment by manual extension without the need for large-scale equipment. This foldable house has a high expansion ratio and includes built-in storage compartments for supporting facilities, making it easy to transport and reducing transportation costs. The addition of an umbrella-like support structure and an external support frame ensures the foldable house's structural stability. Solar panels above the roof provide energy for daily activities for those living within the foldable house, making it environmentally friendly.

[0072] For ease of understanding, the overall structure and integrated construction process of the double-layer foldable house provided by the present invention will be briefly described below using a specific usage scenario as an example.

[0073] Please continue to refer to Figure 1-7 In this specific usage scenario, the double-layer foldable house provided by the present invention includes a retractable top plate 1, a top plate 2, a top telescopic rod 3, a movable hinge 5, and multiple upper side plates (such as Figure 2 The first upper side plate 6, the second upper side plate 16, the third upper side plate 15 and the fourth upper side plate 14) and multiple lower side plates (such as Figure 2 As shown, the second lower side panel 7, the second lower side panel 8, the third lower side panel 9 and the fourth lower side panel 13), the retractable bottom panel 10, the bottom panel 11, the telescopic ladder 17, the telescopic rod 18 connecting the top panel and the bottom panel, the door body 19, the self-locking buckle 20 and the hidden panel 22. The foldable house is prefabricated and folded in the factory and unfolded on site.

[0074] Among them, the first upper side panel 6, the second upper side panel 16, the third upper side panel 15 and the fourth upper side panel 14 are respectively vertically fixed on the top panel 2, and the second lower side panel 7, the second lower side panel 8, the third lower side panel 9 and the fourth lower side panel 13 are respectively vertically fixed on the bottom panel 11, and are fully unfolded to form the four side wall structures of the foldable house.

[0075] After folding, the upper and lower side panels are secured using frame assemblies 4 and movable hinges 5 to prevent the side panels from automatically unfolding. The top panel 2 and retractable top panel 1 apply load to the side panels via self-locking buckles 20, movable hinges 5, and bolts. The bottom panel 11 and retractable bottom panel 10 also apply load via telescopic rods 18 connecting the top and bottom panels.

[0076] In this embodiment, the first upper side panel 6, the second upper side panel 16, the third upper side panel 15, the fourth upper side panel 14, the first lower side panel 7, the second lower side panel 8, the third lower side panel 9, and the fourth lower side panel 13 can all be unfolded again. When the house is folded, the first upper side panel 6 and the second upper side panel 16 can be folded together, the first lower side panel 7 and the second lower side panel 8 can be folded together, the third lower side panel 9 and the fourth lower side panel 13 can be folded together, and the fourth upper side panel 14 and the third upper side panel 15 can be folded together. When the house is fully unfolded, after the first upper side panel 6, the second upper side panel 16, the third upper side panel 15, and the fourth upper side panel 14 are unfolded upward, the inner side of the upper side wall panel contains a hidden panel 22 that needs to be unfolded again. When the house is fully unfolded, after the first lower side panel 7, the second lower side panel 8, the third lower side panel 9, and the fourth lower side panel 13 are unfolded downward, the inner side of the upper side wall panel contains a hidden panel 22 that needs to be unfolded again.

[0077] In this embodiment, the door 19 contained within the first lower side panel 7 is usable only when the house is fully extended. The door handle of the door 19 is embedded and does not interfere with the folding of the house. The door 19 is connected to the first lower side panel 7 via a rotating shaft. The movable hinge 5 is made of a material with a certain degree of flexibility and ductility. The movable hinge 5 is installed in a pre-reserved groove in the side wall panel, which does not interfere with the folding and extension. The self-locking buckle 20 has a buckle groove 29 in the pre-reserved position in the side wall panel. The buckle 28 is installed in the buckle groove 29, and the buckle 28 is provided with a spring 27. When folded, the buckle 28 is completely located on one side wall panel. When extended, the buckle 28 is located between the two side wall panels.

[0078] In this embodiment, the umbrella-shaped support plate 23 is connected to both the side wall and the hidden panel 22. Bolts secure the umbrella-shaped support plate 23 to the side wall and hidden panel 22. The hidden panel 22 applies a load to the side wall via the pivot and the umbrella-shaped support plate 23. Simultaneously, the hidden panel 22 and the umbrella-shaped support plate 23 apply a load to the bottom panel via the support rod 26. The umbrella-shaped support plate 23 provides support for the hidden panel 22, stabilizing the overall two-story structure of the foldable house. The hidden panel 22 has a pre-scalloped, fan-shaped relief notch at the location where the telescopic ladder 17 is located, making it easier for people to fold up and down the second floor of the house.

[0079] In this embodiment, the frame top plate 21, the frame bottom plate 25 and the side frame 24 are connected and fixed to the side wall plates, the top plate 2 and the bottom plate 11 by grooves and bolts, and the gaps are filled with sealing strips.

[0080] Furthermore, the storage box 12 of the housing supporting components includes items such as a folding bed, folding tables and chairs, a folding cabinet, housing disassembly and assembly tools, and lamps, providing an integrated facility for the housing user and facilitating the use of the housing.

[0081] The above-mentioned integrated construction method of the double-layer foldable house comprises the following steps:

[0082] 1) Open the frame assembly 4, fix the lower end of the connected hydraulic telescopic rod 18 to the upper side of the bottom plate 11, and fix the upper end of the hydraulic telescopic rod 18 to the lower side of the top plate 2;
