Description

Technical Field

[0001] This utility model belongs to the field of Mongolian yurt construction technology, specifically relating to a prefabricated Mongolian yurt that is easy to assemble and disassemble and has excellent thermal insulation performance, suitable for temporary or semi-permanent residential buildings in outdoor camping, folk tourism display and other scenarios. Background Technology

[0002] The yurt is a traditional dwelling of nomadic peoples such as the Mongols. Its round, domed shape is well-suited to the grassland climate (reducing wind resistance and preventing snow accumulation) and facilitates migration as people move with their livestock, making it a carrier of nomadic culture. It also holds unique value in modern folk tourism and outdoor camping. Traditional yurts are supported by wooden frames (khana, toonao, uni) and covered with felt. They are flexible to assemble and disassemble without damaging grassland vegetation, but their limitations have become increasingly apparent with social development.

[0003] Traditional Mongolian yurts have poor living performance. The felt is not good at heat insulation, rain and moisture protection, fire resistance and light transmission, which affects the comfort of living. The construction depends on manual experience, which is time-consuming and of inconsistent quality. After disassembly, the parts are difficult to transport and store, and it is difficult to adapt to the needs of rapid mass construction and relocation in modern scenarios. The wooden parts are handmade, and the specifications are difficult to standardize, which makes it impossible to mass-produce them industrially, resulting in high costs and long supply cycles.

[0004] Existing improved yurts have shortcomings: yurts with brick, cement, or reinforced concrete structures, while improving stability and durability, are complex to construct, have long construction periods, require a lot of labor, are costly, and cannot be moved. They also easily pollute the environment and waste raw materials. Yurts with metal frames covered with wall panels or tarpaulins are cumbersome to assemble, heavy, and have poor insulation and soundproofing. The joints are prone to leakage and loosening, and safety is difficult to guarantee in severe weather.

[0005] Even with some prefabricated yurt technology, there are still shortcomings: some solutions have complex connection structures between the wall panels and the foundation, increasing installation difficulty; some wall panel splicing nodes disrupt the continuity of the insulation layer, reducing insulation performance; and some prefabricated components have poor versatility in specifications, making it difficult to flexibly adjust the size of the yurt to suit different scenarios.

[0006] With the development of outdoor camping and grassland cultural tourism, the market urgently needs prefabricated yurts that combine the characteristics of traditional Mongolian yurt culture with modern architectural performance to solve the problems of low construction efficiency, poor living comfort, and weak adaptability of existing yurts. Utility Model Content

[0007] The purpose of this utility model is to overcome the defects of the existing technology and provide a prefabricated yurt that inherits and carries forward the core advantages of the traditional yurt, such as its round dome and ease of relocation. At the same time, through modular design and optimized structure, it achieves the characteristics of structural stability, good heat preservation, easy construction, and beautiful appearance, making it suitable for various scenarios such as outdoor camping and folk tourism display.

The steel plates possess excellent structural strength and corrosion resistance, ensuring the long-term stability of the wall structure. Insulation layers and backing boards are sequentially installed on the inner sides of the main wall panel, door panel, window panel, and window panel. The insulation layer effectively blocks heat transfer between the interior and exterior, improving living comfort, while the backing boards protect the insulation layer and optimize the interior visual effect. All wall panels include curved square panels, with two stamped, double-folded side panels on both sides. The folding angle is controlled between 86-90°, ensuring a tight fit without obvious gaps when adjacent wall panels are joined, and facilitating industrial stamping. Curved end plates are welded to the top and bottom of the curved square panels, maintaining the same curvature as the curved square panels. This enhances the structural strength of the upper and lower ends of the wall panels and ensures a neat ring structure after the wall is joined.

[0009] The aforementioned roof includes a skylight containing a circular ring formed by bending a steel plate. This ring serves as the core supporting component of the skylight, ensuring the overall structural stability of the skylight. Several radially arranged diagonal support rods connect the ring to the wall, providing uniform and stable support for the roof. Between adjacent diagonal support rods are roof grooves made of steel plate, filled with insulation material to further enhance the roof's insulation performance. Above the roof grooves and insulation material, a steel plate roof panel is installed, effectively blocking rainwater and dust, forming the outer protective structure of the roof and protecting the internal components from external environmental influences.

[0010] Preferably, the top groove is composed of a fan-shaped groove bottom plate and two folded groove side plates, wherein the two folded groove side plates are formed by stamping on both sides of the fan-shaped groove bottom plate; the top groove is connected to the adjacent inclined support rod by the two folded groove side plates, and the connection position is fixed by self-tapping screws passing through the two folded groove side plates and the inclined support rod to ensure that the top groove is firm and reliable and does not shake after installation.

The connecting plate includes strips for connecting the inner side of the upper end of the wall, and obtuse-angled folded plates are arranged at equal intervals on the upper edge of the strips for connecting the bottom plate of the fan-shaped groove. The connecting plate can support and position the top groove, ensuring that the installation position of the top groove is accurate and avoiding displacement after installation.

[0015] Preferably, the diagonal support rod is made of metal tubing, which combines good strength with lightweight, facilitating transportation and installation. The upper end of the diagonal support rod is connected to the ring of the skylight via a plug-in structure, and the lower end is connected to the wall via a support member. Both ends of the curved wall end plate at the upper end of the wall are provided with two strip holes. The support member is formed by stamping steel plate and includes four wall plate connecting claws corresponding to the strip holes of the adjacent curved wall end plates, as well as one diagonal support rod connecting claw fixedly connected to the lower end of the diagonal support rod. The support member can connect the upper ends of adjacent wall plates and a diagonal support rod together, significantly enhancing the connection stability between the wall and the roof.

[0016] Preferably, a steel plate stamping frame is installed on the outer side of the upper end of the wall. The frame includes side panels, with right-angled two-fold plates evenly spaced along the lower edge of the side panels and acute-angled two-fold plates evenly spaced along the upper edge. The side panels surround and connect to the outer side of the upper end of the wall. The right-angled two-fold plates enhance the tightness of the connection between the frame and the wall, while the acute-angled two-fold plates support the lower end of the fan-shaped top panel, providing stable support for the top panel.

[0025] The following detailed description of specific embodiments of the prefabricated yurt of this utility model is provided in conjunction with the accompanying drawings. These embodiments are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] I. Specific Embodiments of the Prefabricated Mongolian Yurt of this Utility Model like Figures 1 to 16 As shown, the prefabricated yurt of this embodiment includes walls (1) and a roof (2), which together form a complete living space, suitable for temporary or semi-permanent living needs such as outdoor camping and folk tourism displays.

[0027] (a) Wall structure The wall (1) is composed of a main wall panel (13), a door wall panel (14), a window wall panel (15), and a window wall panel (16) connected in a ring. All wall panels are made of steel plate, which has good rigidity and corrosion resistance, and can ensure the stability of the wall for long-term use. The core structure of each wall panel is an arc-shaped square panel. The arc of the arc-shaped square panel is designed according to the overall ring size of the yurt to ensure that a regular circular wall is formed after splicing. The two sides of the arc-shaped square panel are made into two-fold wall side panels by stamping process. The folding angle is controlled at 86-90°. In this embodiment, 88° is preferred. This angle can make the two-fold wall side panels of adjacent wall panels fit tightly and there is no obvious gap after splicing. At the same time, it is convenient for stamping processing and on-site assembly. The upper and lower ends of the arc-shaped square panel are respectively welded with arc-shaped wall end plates. The arc of the arc-shaped wall end plates is consistent with that of the arc-shaped square panel to ensure that the weld is firm and there are no problems of false welding or missing welding. The arc-shaped wall end plates can enhance the structural strength of the upper and lower ends of the wall panel and avoid deformation of the wall panel edges.

[0028] On the inner side of each wall panel, an insulation layer (17) and a backing board (18) are installed sequentially from the outside to the inside. The insulation layer (17) is made of polyurethane insulation board, which has a low thermal conductivity, excellent insulation performance, and is lightweight, so as not to increase the weight of the wall panel excessively. It is fixed to the inner side of the wall panel with a special adhesive.

Obtuse angle folded plates (62) are arranged at equal intervals on the upper side of the strips (61). The obtuse angle folded plates (62) and the strips (61) are stamped together. Its obtuse angle is designed to be 116°, which can fit tightly with the fan-shaped groove bottom plate (221) of the top groove (22) to provide stable support for the top groove (22).

[0031] An edge frame (4) is installed on the outer side of the upper end of the wall (1). The edge frame (4) is formed by stamping steel plate and includes edge strips (41), right-angled two-fold plates (42), and acute-angled two-fold plates (43). The edge strips (41) are fixed to the arc-shaped wall end plate on the outer side of the upper end of the wall (1) by self-tapping screws. Right-angled two-fold plates (42) are arranged at equal intervals on the lower side of the edge strips (41). The right-angled two-fold plates (42) are integrally stamped with the edge strips (41) and the right angle is 90°. The upper part is arranged with two acute-angled folding plates (43) at equal intervals. The acute-angled folding plates (43) are also integrally stamped with the surrounding strips (41). The acute angle is 64° and is used to support the fan-shaped top panel (241) of the yurt top plate (24). On the periphery of the right-angled folding plates (42) and the acute-angled folding plates (43) of the surrounding frame (4), the decorative strips (5) are fixed with self-tapping screws. The decorative strips (5) are made of thin steel plates and the surface can be sprayed according to requirements to improve the appearance of the yurt.

[0032] In addition, two strip holes (19) are opened at both ends of the upper arc-shaped wall end plate of the wall (1). The length of the strip hole (19) is 4 cm and the width is 0.5 cm. They are used to cooperate with the wall plate connecting claw (31) of the support member (3). The support member (3) is formed by stamping steel plate and includes four wall plate connecting claws (31) and one inclined support connecting claw (32). The four wall plate connecting claws (31) correspond to the strip holes (19) on the arc-shaped wall end plates of the two adjacent wall plates respectively. The four wall plate connecting claws (31) are inserted into the strip holes (19) of the adjacent arc-shaped wall end plates respectively to fix the support member (3) to the adjacent wall plates. The inclined support connecting claw (32) is welded to the lower end of the inclined support (21) for fixed connection.

[0033] (ii) Top Structure The roof (2) includes a skylight (7), a diagonal support rod (21), a roof groove (22), insulation material (23), and a roof plate (24). In this embodiment, there are 16 diagonal support rods (21), roof grooves (22), and roof plates (24), which are evenly distributed radially.

[0034] Assembly of the skylight (7): The skylight (7) includes a ring (71), a support beam (72), a connector (73), a skylight column (74), and a skylight cover (75). The ring (71) is formed by bending steel plate and then fixing it by welding. The weld is ground smooth. The diameter of the ring (71) is designed according to the overall size of the yurt to ensure that it is located in the center of the top (2) of the yurt. Inside the ring (71), the support beam (72) is welded along the diameter direction. The support beam (72) is made of steel pipe and is fully welded to the ring (71) to enhance the structural strength of the ring (71) and prevent the ring (71) from deforming under stress. On the outside of the ring (71), connectors are welded at equal intervals. 73) The plug claw (73) is made of steel pipe and the number is the same as that of the diagonal support (21). Six skylight columns (74) are evenly welded on the top of the ring (71). The height of the skylight column (74) is 15 cm. The welding point is reinforced to ensure a firm connection. The upper end of the skylight column (74) is welded with a skylight cover (75). The skylight cover (75) is made of steel plate and is circular. The diameter of the skylight cover (75) is larger than the inner diameter of the ring (71) and can completely cover the skylight (7) to prevent rainwater and dust from entering the room.

[0035] Installation of the diagonal support rod (21): The diagonal support rod (21) is made of metal pipe. The metal pipe is made of galvanized steel pipe, which has good corrosion resistance and strength. The length of the diagonal support rod (21) is designed according to the height of the wall and the curvature of the roof to ensure that it is inclined at a 26° angle after installation. First, insert the four wall plate connecting claws (31) of the support rod (3) into the strip holes (19) of the adjacent curved wall end plates to fix the support rod (3) to the wall (1). Then, weld the lower end of the diagonal support rod (21) to the diagonal support rod connecting claw (32) of the support rod (3). The upper end of the diagonal support rod (21) is fitted onto the plug claw (73) on the outside of the skylight (7) ring (71). Adjust the verticality and tilt angle of the diagonal support rod (21) appropriately to ensure that all diagonal support rods (21) are subjected to uniform force.

[0036] Installation of the top groove (22): The top groove (22) is formed by stamping steel plate, including a fan-shaped groove bottom plate (221) and two folded groove side plates (222) on both sides. The arc of the fan-shaped groove bottom plate (221) is consistent with the arc of the top of the bag. The folding angle of the two folded groove side plates (222) is designed to be 90°, so that it can fit tightly with the outside of the inclined support rod (21). Place the top groove (22) between two adjacent inclined supports (21), so that the two folded groove side plates (222) overlap the outside of the inclined supports (21). Adjust the position of the top groove (22) so that the lower end of the fan-shaped groove bottom plate (221) fits against the obtuse angle one-fold plate (62) of the upper inner connecting plate (6) of the wall (1). Then, fix the top groove (22) to the inclined supports (21) by passing self-tapping screws through the two folded groove side plates (222) and the inclined supports (21). At the same time, fix the fan-shaped groove bottom plate (221) to the obtuse angle one-fold plate (62) by self-tapping screws to ensure that the top groove (22) is installed firmly and without shaking.

[0037] Filling of insulation material (23): Insulation material (23) is filled inside each top groove (22). The insulation material (23) is glass wool, which has excellent insulation performance and is lightweight. When filling, the glass wool needs to be cut into a shape that matches the internal size of the top groove (22) to ensure that the internal space of the top groove (22) is filled without gaps. After filling, the edges of the glass wool are fixed with special tape to prevent the glass wool from shifting.

[0038] Installation of the top panel (24): The top panel (24) is formed by stamping steel plate and includes a fan-shaped top panel (241), a single-fold top side panel (242) and a three-fold top side panel (243). The arc of the fan-shaped top panel (241) is consistent with the arc of the top panel, and its area is adapted to the area enclosed by the top groove (22) and the two adjacent diagonal support rods (21). The folding angle of the single-fold top side panel (242) is 90°, and the folding angles of the three-fold top side panel (243) are 90°, 90° and 90° respectively, to ensure that the adjacent top panels (24) can be tightly fastened. Cover the top plate (24) over the top groove (22) and the insulation material (23), so that the lower end of the fan-shaped top panel (241) is placed on the acute angle two-fold plate (43) of the edge frame (4), and adjust the position of the top plate (24); when installing adjacent top plates (24), insert the one-fold top side plate (242) of one side top plate (24) into the three-fold top side plate (243) of the other side top plate (24) to achieve a snap-fit ​​connection. After snap-fit, apply neutral silicone sealant to the connection. Apply the sealant evenly with a thickness of 2-3 mm to ensure a waterproof seal and prevent rainwater leakage.

[0039] II. Working principle of this utility model The core working principle of this prefabricated yurt revolves around "modular support - layered insulation - convenient connection": Structural support principle: The wall is formed by the circular splicing of steel plate wall panels to create a closed external enclosure structure. The two-fold wall side panels on both sides of the wall panel and the arc-shaped wall end panels at the top and bottom enhance its rigidity. The roof is centered on the skylight ring and connected to the wall through radial diagonal supports. The lower ends of the diagonal supports are fixed to the wall panels with the support members, forming a "center-radial" support frame. The support members also connect adjacent wall panels, further enhancing the overall connection between the wall and the roof. The diagonal supports not only connect the wall to the skylight ring, but also provide uniform and stable support for the roof. The acute-angled two-fold plates of the perimeter frame support the roof plate, so that the stress on the roof structure is evenly distributed. The lower end of the wall is bolted to the base or foundation to ensure the stability of the overall structure and resist external loads.

[0040] Insulation principle: The wall adopts a three-layer structure of "steel plate + insulation layer + lining board". The insulation layer blocks the heat transfer of the wall. The roof adopts a three-layer structure of "roof panel + insulation material + roof groove". The insulation material fills the interior of the roof groove to form a continuous roof insulation layer. At the same time, the wall panel joints are tightly fitted by two folded wall side panels, and the roof panel is sealed with sealant by folded edges. The sealant can further seal the joint gaps to prevent cold air from seeping in or hot air from escaping, reduce the thermal bridging effect caused by gaps, achieve overall insulation of the wall and roof, and ensure stable indoor temperature.

[0041] Connection principle: All components adopt a modular design. The wall panels are spliced ​​by two folded wall side panels, the roof groove is fixed to the diagonal support rod with self-tapping screws, the roof panel is connected by folded edge fastening, and the skylight is connected to the diagonal support rod and the skylight column to the skylight cover through plug-in claws. All of these require no complicated construction process, realize quick assembly and disassembly, and meet the needs of flexible relocation.
