Description

Technical Field

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

[0002] Prefabricated construction is a type of building where prefabricated building components and accessories are manufactured in a factory, transported to the construction site, and assembled on-site using reliable connection methods. In different regions, appropriate prefabricated materials and structural designs must be used based on the local climate, topography, and other conditions.

[0003] In related technologies, in high-risk areas such as coastal and mountainous regions, due to environmental factors such as wind coming from different directions and strong winds, the use of inappropriate prefabricated house structures may result in poor wind resistance of the prefabricated houses, leading to structural damage or even collapse. Summary of the Invention

[0004] This application provides a prefabricated house structure that can improve the technical problem in related technologies where prefabricated house structures are difficult to adapt to wind loads from different wind directions during environmental changes, leading to house damage.

[0005] This application provides a prefabricated housing structure, including:

[0006] Subbase;

[0007] The foundation, set on the subbase, is used for load-bearing;

[0008] Precast walls, set on the aforementioned foundation; and

[0009] The roof includes a top floor slab and a windproof device, wherein the top floor slab is disposed on the precast wall; a first end of the windproof device is disposed on the top floor slab, and a second end of the windproof device is disposed on the precast wall;

[0010] The windproof device includes a shielding assembly, which comprises multiple sliding rods and multiple shielding parts. One end of each sliding rod is slidably mounted on the top floor slab, and the other end is slidably mounted on the precast wall. One end of each shielding part is connected to one of the sliding rods, and the other end is connected to another sliding rod adjacent to the first sliding rod. The windproof device has a windproof state in which the multiple sliding rods move the multiple shielding parts to form a wind-relief angle opposite to the incoming wind for wind protection, and a sun-exposed state in which the multiple sliding rods fold and retract the multiple shielding parts.

[0011] The technical solutions described in this application embodiment have at least the following technical effects:

[0012] The subbase layer distributes the weight and load of the prefabricated house, thus providing more stable support. The foundation is placed on the subbase and supports the weight load of the prefabricated house, ensuring its stability on the ground. Prefabricated walls are placed on the foundation and support the weight load of the roof, floor, etc., as well as bearing loads from the natural environment such as wind, snow, and seismic loads that affect the structure. Prefabricated walls also divide the interior space of the prefabricated house structure to form different rooms and areas. The roof protects the interior space of the prefabricated house structure from external environmental damage (such as strong winds, rain, and snowfall). The top floor slab is placed on the prefabricated walls to protect the interior space of the prefabricated house structure.

[0013] Because the roof includes windproof devices installed on the top floor slab and prefabricated walls, when the prefabricated house structure is subjected to strong wind loads, the windproof devices switch from a sun-exposed state to a wind-proof state. Multiple sliding rods move multiple shielding parts to create an angle of deflection opposite to the incoming wind between adjacent shielding parts. Due to the sharper shape of the deflection angle, the pressure difference between the airflow and the surface of the shielding part is reduced, thereby reducing the wind load on the shielding part. When it is calm and windless, and the house needs sunlight, the windproof devices switch from a wind-proof state to a sun-exposed state. Multiple sliding rods fold and retract multiple shielding parts to prevent the shielding parts from blocking sunlight from entering the interior space of the prefabricated house structure.

[0014] In some embodiments, the windproof device further includes:

[0015] A first sliding ring is disposed on the top floor slab, and one end of the sliding rod is slidably disposed on the first sliding ring; and

[0016] The second sliding ring is disposed on the precast wall and located below the first sliding ring, and the other end of the sliding rod is slidably disposed on the second sliding ring.

[0017] In some embodiments, the prefabricated wall comprises:

[0018] Multiple prefabricated exterior walls are installed on the foundation slab; and

[0019] Multiple precast wall columns are set on the foundation slab and connected to two adjacent precast exterior walls;

[0020] The prefabricated exterior walls, the prefabricated wall columns, and the top floor slab form a closed room space, and the second sliding ring is disposed on the prefabricated wall columns.

[0021] In some embodiments, the occlusion component further includes:

[0022] A first rotation drive unit is disposed on the first sliding ring; the first rotation drive unit includes a plurality of first sub-rotation drive units, and the power output end of each first sub-rotation drive unit is connected to each of the sliding rods in a corresponding manner, for driving the sliding rods to move on the first sliding ring and the second sliding ring, so that the windproof device switches between the windproof state and the sun exposure state.

[0023] In some embodiments, the occlusion component further includes:

[0024] A wind direction detection unit is disposed on the first sliding ring. The wind direction detection unit is communicatively connected to the first rotation drive unit and is used to detect the wind direction.

[0025] In some embodiments, the windproof device further includes:

[0026] A support portion is disposed on the top floor slab; the first sliding ring is disposed on the support portion.

[0027] In some embodiments, the first sliding ring includes a plurality of first sub-sliding segments, which are detachably connected to each other;

[0028] The second sliding ring includes a plurality of second sub-sliding segments, which are detachably connected to each other.

[0029] In some embodiments, the shielding assembly further includes a plurality of stabilizing components, which are stacked along the length direction of the support portion, and the stabilizing components include:

[0030] A locking component includes a locking part and two connecting parts; one end of one of the connecting parts is connected to the sliding rod, the other end of the other connecting part is connected to the locking part, one end of the other connecting part is connected to the locking part, and the other end of the other connecting part is connected to the support part; in the windproof state, the one connecting part connected to the sliding rod is tightened, and the locking part restrains the sliding rod through the one connecting part to stabilize the windproof state; in the sun exposure state, the one connecting part connected to the sliding rod is relaxed so that the locking part does not restrict the rotation of the sliding rod.

[0031] In some embodiments, the locking element further includes:

[0032] A take-up drive unit is connected to the support unit. The power output end of the take-up drive unit is connected to the other connecting part and connected to the locking part through the other connecting part. The take-up drive unit is used to pull the connecting part so that one of the connecting parts is tightened or loosened, thereby allowing the windproof device to switch between the windproof state and the sun exposure state.

[0033] In some embodiments, the stabilizing component further includes:

[0034] Multiple second rotation drive units are disposed on the support unit, and the power output ends of the second rotation drive units are connected to each of the take-up drive units in a corresponding manner, for driving the locking unit to rotate as the sliding rod rotates.

[0054] Prefabricated construction is a type of building where prefabricated building components and accessories are manufactured in a factory, transported to the construction site, and assembled on-site using reliable connection methods. In different regions, appropriate prefabricated materials and structural designs must be used based on the local climate, topography, and other conditions.

[0055] In related technologies, in high-risk areas such as coastal and mountainous regions, due to environmental factors such as wind coming from different directions and strong winds, the use of inappropriate prefabricated house structures may result in poor wind resistance of the prefabricated houses. Strong winds may exert pressure on the walls, causing them to tilt, crack, or collapse. Strong winds may also tear or peel off the roof covering material, damaging the building roof.

[0056] Based on this, in order to improve the technical problem that prefabricated housing structures in related technologies are difficult to adapt to wind loads from different wind directions during environmental changes, which can lead to housing damage, the embodiments of this application provide the following solutions.

[0057] Please refer to the following: Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 This application provides a prefabricated house structure 100, including a subfloor, a foundation 10, prefabricated walls 20, and a roof 30. The foundation 10 is disposed on the subfloor and is used for load-bearing. The prefabricated walls 20 are disposed on the foundation 10. The roof 30 includes a top floor slab 31 and a windproof device 32. The top floor slab 31 is disposed on the prefabricated walls 20. The first end 321 of the windproof device is disposed on the top floor slab 31, and the second end 322 of the windproof device is disposed on the prefabricated walls 20.

[0058] The windproof device 32 includes a shielding assembly 323. The shielding assembly 323 includes multiple sliding rods 3231 and multiple shielding parts 3232. One end of each sliding rod 3231 is slidably mounted on the top floor slab 31, and the other end is slidably mounted on the precast wall 20. One end of each shielding part 3232 is connected to one of the sliding rods 3231, and the other end is connected to another sliding rod 3231 adjacent to it. The windproof device 32 has a windproof state where the multiple sliding rods 3231 move the multiple shielding parts 3232 to form a wind-relief angle 323201 opposite to the incoming wind for wind protection, and a sun-exposed state where the multiple sliding rods 3231 fold and retract the multiple shielding parts 3232.

[0059] It is understood that the subbase can be of various types, such as concrete subbase, steel plate subbase, crushed stone subbase, etc., but is not limited to these. The foundation 10 can be of various types, such as precast reinforced concrete foundation, prestressed concrete foundation, etc., but is not limited to these. The precast wall 20 can include various types of walls, such as precast concrete wall, composite wall panel, steel frame wall, etc., but is not limited to these. The top floor slab 31 can be of various types, such as precast concrete floor slab, steel frame floor slab, reinforced concrete floor slab, composite floor slab, etc., but is not limited to these. The connection method between the sliding rod 3231 and the precast wall 20 can be various, such as sliding plug connection, wheel groove connection, etc., but is not limited to these. The shielding part 3232 can be made of various materials with windproof, rainproof and foldable properties, such as latex coated cloth, polyvinyl chloride coated cloth, nylon canvas, etc., but is not limited to these. In the windproof state, the wind-relief angle 323201 formed by two adjacent shielding parts 3232 opposite to the incoming wind can be a variety of angles that are conducive to windproofing (for example, it can be 60° to 90°, specifically 60°, 65°, 70°, 80°, 90°, etc., but not limited to this).

[0060] As can be seen from the above, the prefabricated house structure 100 provided in this application embodiment has a subbase layer used to distribute the weight and load of the prefabricated house, prevent settlement of the prefabricated house and the penetration of soil moisture into the prefabricated house structure 100, thereby providing more stable support for the prefabricated house. The foundation 10 is set on the subbase layer. The foundation 10 is used to support the weight load of the prefabricated house and to resist natural disasters such as earthquakes and wind loads, so that the building stands firmly on the ground. Prefabricated walls 20 are set on the foundation 10. The prefabricated walls 20 are used to support the weight load of the roof, floor, etc., of the prefabricated house, and to bear the loads affecting the prefabricated house structure 100 caused by natural environmental factors such as wind loads, snow loads, and earthquake loads. The prefabricated walls 20 are also used to divide the internal space of the prefabricated house structure 100 to form different rooms and areas. The roof 30 is used to protect the internal space of the prefabricated house structure 100 from external environmental damage (such as strong winds, rain, snowfall, etc.). The top floor slab 31 is set on the prefabricated wall 20 to protect the interior space of the prefabricated house structure 100.

[0061] When the prefabricated building structure 100 is subjected to a strong wind load, the windproof device 32 switches from a sun-exposed state to a windproof state. Multiple sliding rods 3231 drive multiple shielding parts 3232 to move so that adjacent shielding parts 3232 form a wind-relief angle 323201 opposite to the incoming wind. Due to the sharper shape of the wind-relief angle 323201, air molecules are brought closer together, thus forming a higher velocity region. The higher velocity results in lower static pressure, so the wind-relief angle 323201 can better reduce the wind load. The wind-relief angle 323201 can also reduce turbulence and eddies when the airflow passes through the wind-relief angle 323201, thereby reducing energy loss and wind load. The wind-relief angle 323201 formed by two adjacent shielding parts 3232 can further push the separation point of the airflow, extending the distance the airflow travels across the surface of the shielding part 3232, which helps to delay airflow separation, thereby reducing the pressure difference between the airflow and the surface of the shielding part 3232, and thus reducing the wind load on the shielding part 3232. When it is calm and windless and sunlight is needed inside the house, the windproof device 32 switches from the windproof state to the sunlight exposure state. Multiple sliding rods 3231 drive multiple shielding parts 3232 to fold and retract, so as to prevent the shielding parts 3232 from blocking sunlight from entering the interior space of the prefabricated house structure 100.

[0062] In some embodiments, please refer to the following: Figure 1 and Figure 2 The windproof device 32 also includes a first sliding ring 324 and a second sliding ring 325. The first sliding ring 324 is disposed on the top floor slab 31, and one end of the sliding rod 3231 is slidably disposed on the first sliding ring 324. The second sliding ring 325 is disposed on the precast wall 20 and located below the first sliding ring 324. The other end of the sliding rod 3231 is slidably disposed on the second sliding ring 325. The diameter of the second sliding ring 325 is larger than the diameter of the first sliding ring 324.

[0063] The connection between the first sliding ring 324 or the second sliding ring 325 and the precast wall 20 can be in various ways, such as a locking pin connection, a tenon and mortise connection, a threaded connection, etc., but is not limited to these. The connection between the sliding rod 3231 and the first sliding ring 324 or the second sliding ring 325 can be in various ways, such as a plug connection, a groove connection, etc., but is not limited to these.

[0064] With this configuration, the sliding rod 3231 rotates around the prefabricated wall 20 along the circular track of the first sliding ring 324 and the second sliding ring 325. The second sliding ring 325 is below the first sliding ring 324, and the diameter of the second sliding ring 325 is larger than the diameter of the first sliding ring 324. This allows the sliding rod 3231 to drive the shielding part 3232 to form a certain angle between itself and the horizontal plane, which is beneficial for reducing wind load (for example, it can be 30° to 60°, specifically 30°, 45°, 50°, 55°, 60°, etc., but not limited to this). The second sliding ring 325 is set on the prefabricated wall 20, so that the shielding part 3232 connected to the sliding rod 3231 set on the second sliding ring 325 can shield part of the prefabricated wall 20, providing wind protection for the prefabricated wall 20, thereby improving the stability of the prefabricated house structure 100.

[0065] In some embodiments, please refer to the following: Figure 1 and Figure 2 The precast wall 20 includes multiple precast exterior walls 21 and multiple precast wall columns 22. The multiple precast exterior walls 21 are mounted on the foundation 10. The multiple precast wall columns 22 are mounted on the foundation 10 and connected to adjacent precast exterior walls 21. A closed room space is formed between the multiple precast exterior walls 21, the multiple precast wall columns 22, and the top floor slab 31. A second sliding ring 325 is mounted on the precast wall columns 22.

[0066] It is understood that the precast exterior wall 21 can be of various types, such as precast concrete wall, prestressed concrete wall, composite wall panel, steel frame wall, etc., but is not limited to these. The precast wall column 22 can also be of various types, such as reinforced concrete wall column, prestressed concrete wall column, pressure-membrane wall column, etc., but is not limited to these. The connection method between the precast wall column 22 and the precast exterior wall 21 can be various, such as concrete pouring and solidification connection, welding, precast tenon and mortise connection, etc., but is not limited to these. The connection method between the second sliding ring 325 and the precast wall column 22 can be various, such as locking pin connection, tenon and mortise connection, threaded connection, etc., but is not limited to these.

[0067] This arrangement enhances the overall structural stability of the prefabricated building structure 100 by combining the prefabricated wall column 22 with the prefabricated exterior wall 21. The prefabricated wall column 22, acting as a support for the prefabricated building structure 100, shares the building's load, providing additional strength and stiffness, helping to resist wind and seismic loads, and improving the stability of the prefabricated building structure 100. The second sliding ring 325, located on the prefabricated wall column 22, does not affect the opening of doors and windows on the prefabricated exterior wall 21.

[0068] In some embodiments, please refer to the following: Figure 1 and Figure 2The shielding assembly 323 also includes a first rotation drive unit 3233. The first rotation drive unit 3233 is disposed on the first sliding ring 324. The first rotation drive unit 3233 includes a plurality of first sub-rotation drive units 32331. The power output end of each first sub-rotation drive unit 32331 is connected to each sliding rod 3231 in a corresponding manner, for driving the sliding rod 3231 to move on the first sliding ring 324 and the second sliding ring 325, so that the windproof device 32 switches between windproof state and sun exposure state.

[0069] It can be understood that the first sub-rotation drive unit 32331 is a rotation drive device used to provide driving force for the movement of the sliding rod 3231 on the first sliding ring 324 and the second sliding ring 325. It can be a variety of drive devices, such as a stepper motor, an AC motor, etc., but is not limited to these.

[0070] With this configuration, the first sub-rotation drive unit 32331 provides rotational driving force for the sliding rod 3231, thereby driving the sliding rod 3231 to move on the first sliding ring 324 and the second sliding ring 325, which in turn drives the two adjacent shielding parts 3232 to form a wind-relief angle 323201 opposite to the incoming wind or drives multiple shielding parts 3232 to fold and retract, so that the windproof device 32 can switch between windproof state and sun exposure state.

[0071] In some embodiments, please refer to the following: Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The shielding assembly 323 also includes a wind direction detection unit 3234. The wind direction detection unit 3234 is disposed on the first sliding ring 324. The wind direction detection unit 3234 is communicatively connected to the first rotation drive unit 3233. The wind direction detection unit 3234 is used to detect the wind direction.

[0072] It is understood that the components used by the wind direction detection unit 3234 to detect wind direction can be of various types, such as electronic wind vanes, GPS wind direction detectors, etc., but are not limited to these. The communication connection between the wind direction detection unit 3234 and the first rotation drive unit 3233 can be in various ways, such as wireless communication, serial communication, etc., but are not limited to these.

[0073] With this configuration, when the wind direction detection unit 3234 detects that the wind force has reached a preset wind force level and the direction of the strongest wind, it transmits the wind direction information to the first rotation drive unit 3233. The first rotation drive unit 3233 then applies a rotational driving force to the sliding rod 3231 according to a preset schedule. This drives the sliding rod 3231 to move the two adjacent shielding parts 3232 to form a wind-relief angle 323201 opposite to the detected strongest wind, resisting wind loads and protecting the prefabricated house structure 100. As the strongest wind direction changes, the wind direction detection unit 3234 transmits the wind direction information to the first rotation drive unit 3233 in real time. The first rotation drive unit 3233 then applies a rotational driving force to the sliding rod 3231 according to a preset schedule. This causes the orientation and angle of the wind-relief angle 323201 to change with the direction of the strongest wind, achieving a better windproof effect and thus better protecting the prefabricated house structure 100.

[0074] Optionally, in some embodiments, the first rotation drive unit 3233 further includes a control component. The control component is communicatively connected to the wind direction detection unit 3234.

[0075] It is understood that control components can be of various types, such as microcontrollers, MCUs, chip controllers, etc., but are not limited to these.

[0076] With this configuration, the first rotation drive unit 3233 is controlled by the control component to apply a rotational driving force to the sliding rod 3231, thereby causing the orientation and angle of the wind relief angle 323201 to change with the wind direction of the strongest wind, so as to achieve a better windproof effect and thus better protect the prefabricated house structure 100.

[0077] For example, please refer to the following: Figures 6 to 8 There are three sliding rods 3231, defined as a first sliding rod 3231a, a second sliding rod 3231b, and a third sliding rod 3231c, which are arranged sequentially along the circumference of the first sliding ring 324. There are two blocking parts 3232, defined as a first blocking part 3232a and a second blocking part 3232b; the first blocking part 3232a is connected to the first sliding rod 3231a and the second sliding rod 3231b, and the second blocking part 3232b is connected to the second sliding rod 3231b and the third sliding rod 3231c.

[0078] The windproof device 32 has several different forms in the windproof state, including a first windproof state, a second windproof state, and a third windproof state. In the first windproof state, the distance between the first sliding rod 3231a and the second sliding rod 3231b is the same as the distance between the third sliding rod 3231c and the second sliding rod 3231b, and the first blocking part 3232a and the second blocking part 3232b are approximately symmetrical about the second sliding rod 3231b. In the second windproof state, the distance between the first sliding rod 3231a and the second sliding rod 3231b is smaller than the distance between the third sliding rod 3231c and the second sliding rod 3231b, and the unfolded area of ​​the first blocking part 3232a is smaller than the unfolded area of ​​the second blocking part 3232b. In the third windproof state, the distance between the first sliding rod 3231a and the second sliding rod 3231b is greater than the distance between the third sliding rod 3231c and the second sliding rod 3231b, and the unfolded area of ​​the first shielding part 3232a is greater than the unfolded area of ​​the second shielding part 3232b.

[0079] With this configuration, when the wind direction detection unit 3234 detects a single and stable incoming wind, the control component controls the first sub-rotation drive unit 32331, whose power output end is connected to the second sliding rod 3231b, to apply a rotational driving force to the second sliding rod 3231b, causing the second sliding rod 3231b to rotate to a position opposite to the incoming wind. The control component also controls the first sub-rotation drive unit 32331, whose power output end is connected to the first sliding rod 3231a, to apply a rotational driving force to the first sliding rod 3231a. Finally, the control component controls the first sub-rotation drive unit 32331, whose power output end is connected to the third sliding rod 3231c, to apply a rotational driving force to the third sliding rod 3231c, so that the first sliding rod 3231a and the third sliding rod 3231c rotate relative to the second sliding rod 3231b to a position where the distance between the first sliding rod 3231a and the second sliding rod 3231b is the same as the distance between the third sliding rod 3231c and the second sliding rod 3231b. The incoming wind flows through the first shielding part 3232a and the second shielding part 3232b, which have equal surface areas, thus improving the windproof efficiency.

[0080] When the wind direction detection unit 3234 detects that the incoming wind includes a first incoming wind and a second incoming wind (where the wind level of the first incoming wind is greater than that of the second incoming wind), the control component controls the first sub-rotation drive unit 32331, whose power output end is connected to the second sliding rod 3231b, to apply a rotational driving force to the second sliding rod 3231b. The control component also controls the first sub-rotation drive unit 32331, whose power output end is connected to the third sliding rod 3231c, to apply a rotational driving force to the third sliding rod 3231c, so that the second sliding rod 3231b and the third sliding rod 3231c rotate, thereby making the line connecting the point where the second sliding rod 3231b is connected to the second sliding ring 325 and the point where the third sliding rod 3231c is connected to the second sliding ring 325 the same as the wind direction of the first incoming wind. The control component controls the first sub-rotation drive unit 32331, whose power output end is connected to the first sliding rod 3231a, to apply a rotational driving force to the first sliding rod 3231a. This causes the first sliding rod 3231a to rotate relative to the second sliding rod 3231b, thereby making the line connecting the point where the second sliding rod 3231b is connected to the second sliding ring 325 and the point where the first sliding rod 3231a is connected to the second sliding ring 325 in the same direction as the second incoming wind. The stronger first incoming wind flows through the second shielding part 3232b with a larger surface area, while the weaker second incoming wind flows through the first shielding part 3232a with a smaller surface area. This makes the windproof device 32 more effective at blocking the stronger first incoming wind and also provides windproof protection for the second incoming wind, thus improving windproof efficiency.

[0081] When the wind direction detection unit 3234 detects that the incoming wind includes a first incoming wind and a second incoming wind (where the wind level of the first incoming wind is greater than that of the second incoming wind), the control component controls the first sub-rotation drive unit 32331, whose power output end is connected to the second sliding rod 3231b, to apply a rotational driving force to the second sliding rod 3231b. The control component also controls the first sub-rotation drive unit 32331, whose power output end is connected to the third sliding rod 3231c, to apply a rotational driving force to the third sliding rod 3231c, so that the second sliding rod 3231b and the third sliding rod 3231c rotate, thereby making the line connecting the point where the second sliding rod 3231b is connected to the second sliding ring 325 and the point where the third sliding rod 3231c is connected to the second sliding ring 325 the same as the wind direction of the second incoming wind. The control component controls the first sub-rotation drive unit 32331, whose power output end is connected to the first sliding rod 3231a, to apply a rotational driving force to the first sliding rod 3231a, causing the first sliding rod 3231a to rotate relative to the second sliding rod 3231b. This causes the line connecting the point where the second sliding rod 3231b is connected to the second sliding ring 325 and the point where the first sliding rod 3231a is connected to the second sliding ring 325 to align with the direction of the first incoming wind. The stronger first incoming wind flows through the first shielding part 3232a with a larger surface area, while the weaker second incoming wind flows through the second shielding part 3232b with a smaller surface area. This makes the windproof device 32 more effective at blocking the stronger first incoming wind and also provides windproof protection against the second incoming wind, thus improving windproof efficiency.

[0082] In some embodiments, please refer to Figure 2 The windproof device 32 also includes a support part 326. The support part 326 is disposed on the top floor slab 31. The first sliding ring 324 is disposed on the support part 326.

[0083] It is understandable that the connection between the support 326 and the top floor slab 31 can be in various ways, such as bolt connection, locking connection, threaded connection, etc., but is not limited to these.

[0084] With this configuration, the support part 326 is used to support and fix the first sliding ring 324, so that the windproof device 32 is more stably installed on the top floor slab 31.

[0085] In some embodiments, please refer to the following: Figures 6 to 8 The first sliding ring 324 includes a plurality of first sub-sliding arc segments 3241, which are detachably connected to each other. The second sliding ring 325 includes a plurality of second sub-sliding arc segments 3251, which are detachably connected to each other.

[0086] It is understood that the first sub-sliding arc segment 3241 can be detachably connected in various ways, such as threaded connection, latching connection, pin connection, etc., but is not limited to these. The second sub-sliding arc segment 3251 can also be detachably connected in various ways, such as threaded connection, latching connection, pin connection, etc., but is not limited to these.

[0087] This configuration allows multiple first sub-sliding segments 3241 to be detachably connected, making the installation of the first sliding ring 324 more convenient and quick. Similarly, multiple second sub-sliding segments 3251 are detachably connected, making the installation of the second sliding ring 325 more convenient and quick.

[0088] Optionally, in some embodiments, please also refer to Figure 1 , Figure 2 and Figure 4 The sliding rod 3231 includes a winding drive unit 32311, a sliding rod winding shaft 32312, and a sliding rod housing 32313. The sliding rod housing 32313 has a winding opening 323101 for the obstruction unit 3232 to enter and exit. The winding opening 323101 extends along the length of the sliding rod housing 32313. The power output end of the first rotation drive unit 3233 is connected to the sliding rod housing 32313. One end of the sliding rod housing 32313 is slidably mounted on a first sliding ring 324, and the other end is slidably mounted on a second sliding ring 325. The winding drive unit 32311 and the sliding rod winding shaft 32312 are disposed within the sliding rod housing 32313. The sliding rod winding shaft 32312 is arranged along the length of the sliding rod housing 32313. A winding drive unit 32311 is disposed at one end near the bottom inner wall of the sliding rod housing 32313. The power output end of the winding drive unit 32311 is connected to the sliding rod winding shaft 32312. A blocking part 3232 is connected to the sliding rod winding shaft 32312.

[0089] It can be understood that the winding drive unit 32311 is a rotation drive device used to provide driving force for the rotation and winding of the sliding rod winding shaft 32312. It can be various types of drive devices, such as stepper motors, AC motors, etc., but is not limited to these.

[0090] With this configuration, the first rotation drive unit 3233 applies a rotational driving force to the sliding rod 3231. When the distance between two adjacent sliding rods 3231 is shortened, the rolling drive unit 32311 applies a rotational driving force to the sliding rod rolling shaft 32312, causing the sliding rod rolling shaft 32312 to rotate. This causes the shielding part 3232 between two adjacent sliding rods 3231 to be rolled up from the sliding rod housing 32313, reducing the usable area of ​​the shielding part 3232 outside the sliding rod housing 32313. This can be used to adjust to a position suitable for flattening the shielding part 3232, or to retract the shielding part 3232 when switching from a windproof state to a sun-exposed state, so as to prevent the shielding part 3232 from blocking sunlight from entering the interior space of the prefabricated house structure 100.

[0091] The first rotation drive unit 3233 applies a rotational driving force to the sliding rod 3231. When the distance between two adjacent sliding rods 3231 increases, the winding drive unit 32311 applies a rotational driving force to the sliding rod winding shaft 32312, causing the sliding rod winding shaft 32312 to rotate. This causes the shielding part 3232 between two adjacent sliding rods 3231 to be released from the sliding rod housing 32313, increasing the usable area of ​​the shielding part 3232 outside the sliding rod housing 32313, thereby enhancing the windproof effect in windproof mode.

[0092] Alternatively, in other embodiments, please refer to [the relevant documentation / reference]. Figure 3 and Figure 5 The shielding assembly 323 also includes a plurality of sub-sliding rods 3236. Each sub-sliding rod 3236 is slidably mounted on the first sliding ring 324 via a connecting component (which may be a connecting rope or a connecting ring). One end of each sub-sliding rod 3236 is stacked and hinged together, and the other end of each sub-sliding rod 3236 is connected to the outer edge of the shielding portion 3232. The sub-sliding rods 3236 are slidably located between two adjacent sliding rods 3231 and connected to the shielding portion 3232. The shielding portion 3232 connecting each pair of adjacent sub-sliding rods 3236 between two adjacent sliding rods 3231 forms a stepped arrangement along one sliding rod 3231 toward the other, so that when the two adjacent sliding rods 3231 move closer together, the sub-sliding rods 3236 between the two adjacent sliding rods 3231 are stacked sequentially.

[0093] With this configuration, the blocking portions 3232 between two adjacent sub-sliding rods 3236 form a gradient in the height direction of the sub-sliding rods 3236. This allows the sliding rods 3231 to fold and retract the blocking portions 3232, with each sub-sliding rod 3236 stacked on top of the adjacent sub-sliding rod 3236. This causes the blocking portions 3232 connected to the sub-sliding rods 3236 to fold and stack on top of the blocking portions 3232 connected to the adjacent sub-sliding rods 3236, until the predetermined folding and retraction effect is achieved.

[0094] Optionally, please refer to the following as well. Figure 3 and Figure 5 The sub-sliding rod 3236 includes a first sub-sliding rod 32361 and a second sub-sliding rod 32362. One end of the first sub-sliding rod 32361 is slidably mounted on the first sliding ring 324 via a connecting component, and the other end of the first sub-sliding rod 32361 is connected to the outer edge of the shielding portion 3232. The first sub-sliding rod 32361 slides between two adjacent sliding rods 3231 and is connected to the shielding portion 3232. The second sub-sliding rod 32362 is connected to the first sub-sliding rod 32361, located above the first sliding ring 324, and connected to the shielding portion 3232. The ends of each second sub-sliding rod 32362 away from the first sub-sliding rod 32361 are stacked and hinged together. In the windproof state, a windproof space is formed between the multiple first sub-sliding rods 32361, the multiple second sub-sliding rods 32362, and the multiple shielding portions 3232. The support part 326, the first rotation drive part 3233, and the wind direction detection part 3234 (e.g., the part of the wind direction detection part 3234 used to collect and analyze wind direction information) are located inside the windproof space. The part of the wind direction detection part 3234 used to detect wind direction is located outside the windproof space.

[0095] With this configuration, the windproof space formed between the multiple first sub-sliding rods 32361, the multiple second sub-sliding rods 32362, and the multiple shielding parts 3232 protects the first rotation drive unit 3233 and the wind direction detection unit 3234 from wind load.

[0096] Optionally, please refer to the following as well. Figure 3 and Figure 5 The shielding assembly 323 also includes a third sub-sliding rod 32363. The third sub-sliding rod 32363 is disposed on the sliding rod 3231, located above the first sliding ring 324, and connected to the shielding part 3232.

[0097] With this configuration, the third sub-sliding rod 32363 is mounted on the sliding rod 3231, and together with multiple first sub-sliding rods 32361 and multiple second sub-sliding rods 32362, it supports the shielding part 3232, thereby enhancing the load-bearing capacity against wind loads and increasing wind protection efficiency.

[0098] In some embodiments, please refer to Figure 2 The shielding component 323 also includes multiple stabilizing components 3235. These stabilizing components 3235 are stacked along the length of the support portion 326, with each stabilizing component 3235 corresponding to a sliding rod 3231. Each stabilizing component 3235 includes a locking member 32351. The locking member 32351 includes a locking portion 323511 and two connecting portions 323512. One end of one connecting portion 323512 is connected to the sliding rod 3231, and the other end of the other connecting portion 323512 is connected to the locking portion 323511; one end of the other connecting portion 323512 is connected to the locking portion 323511, and the other end of the other connecting portion 323512 is connected to the support portion 326. In windproof mode, one of the connecting parts 323512 connected to the sliding rod 3231 is tightened, and the locking part 323511 restrains the sliding rod 3231 through this connecting part 323512 to stabilize the windproof state. In sun-exposed mode, one of the connecting parts 323512 connected to the sliding rod 3231 is relaxed so that the locking part 323511 does not restrict the rotation of the sliding rod 3231.

[0099] It is understood that the connecting part 323512 can be made of various materials used for pulling the locking part 323511, such as steel wire, composite fiber, natural fiber, etc., but is not limited to these. The locking part 323511 can be various structural components that can cooperate with the connecting part 323512 and be used to restrain the sliding rod 3231, such as a magnetic attraction device (another magnetic attraction accessory is fixedly installed on the top floor slab 31, and the magnetic attraction device and the magnetic attraction accessory can be magnetically attracted), a counterweight, etc., but is not limited to these.

[0100] With this configuration, in windproof mode, the sliding rod 3231 moves to a preset position, and one of the connecting parts 323512 connected to the sliding rod 3231 tightens. The locking part 323511 restrains the sliding rod 3231 through one of the connecting parts 323512, temporarily fixing the sliding rod 3231 to stabilize the windproof state and prevent wind load from moving the sliding rod 3231, thereby causing the shielding part 3232 to move and reducing the windproof effect. In sun-exposed mode, one of the connecting parts 323512 connected to the sliding rod 3231 loosens, so that the locking part 323511 does not restrict the rotation of the sliding rod 3231.

[0101] In some embodiments, please refer to Figure 2The locking member 32351 also includes a take-up drive unit 323513. The take-up drive unit 323513 is connected to the support unit 326. The power output end of the take-up drive unit 323513 is connected to another connecting part 323512, and is connected to the locking part 323511 through another connecting part 323512. The take-up drive unit 323513 is used to pull the connecting part 323512, so that one of the connecting parts 323512 is tightened or loosened, thereby allowing the windproof device 32 to switch between windproof state and sun exposure state.

[0102] It is understood that the take-up drive unit 323513 is a take-up drive device that provides driving force to the take-up of the connecting unit 323512. It can be various types of drive devices, such as a winding machine, a stranding machine, etc., but is not limited to these.

[0103] With this configuration, in windproof mode, when the sliding rod 3231 moves to a preset position, the take-up drive unit 323513 releases line from another connecting part 323512, causing the locking part 323511 connected to the other connecting part 323512 to tighten one of the connecting parts 323512 connected to the sliding rod 3231. The locking part 323511 restrains the sliding rod 3231 through one of the connecting parts 323512, temporarily fixing the sliding rod 3231 to stabilize the windproof state and prevent wind load from moving the sliding rod 3231, thereby causing the shielding part 3232 to move and reducing the windproof effect. In sun-exposed mode, the take-up drive unit 323513 takes up line from the other connecting part 323512, causing one of the connecting parts 323512 connected to the sliding rod 3231 to loosen, thus preventing the locking part 323511 from restricting the rotation of the sliding rod 3231.

[0104] In some embodiments, please refer to Figure 2 The stabilizing component 3235 also includes a plurality of second rotation drive units 32352. The plurality of second rotation drive units 32352 are disposed on the support unit 326. The power output ends of the second rotation drive units 32352 are connected one-to-one to each take-up drive unit 323513, for driving the locking unit 323511 to rotate with the rotation of the sliding rod 3231.

[0105] It can be understood that the second rotation drive unit 32352 is a rotation drive device for providing driving force to the rotation of the take-up drive unit 323513. It can be various types of drive devices, such as drive components such as AC motors and stepper motors and transmission components such as gear transmission mechanisms connected to the drive components, but is not limited to these.

[0106] With this configuration, the first rotation drive unit 3233 applies a rotational driving force to the sliding rod 3231, so that when the sliding rod 3231 rotates, the second rotation drive unit 32352 applies a rotational driving force to the take-up drive unit 323513, which is indirectly connected to the sliding rod 3231, so that the take-up drive unit 323513 rotates with the sliding rod 3231, thereby driving the locking part 323511, which is connected to the take-up drive unit 323513 through the connecting part 323512, to rotate with the sliding rod 3231, so as to avoid affecting the rotation of the sliding rod 3231.

[0107] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
