Description

Technical Field

[0002] In traditional ancient buildings, the roof structure mostly adopts a combination of cantilevered eaves and sloped tiles to achieve wind and rain shelter and decorative functions. However, under long-term exposure to the natural environment, especially under extreme weather conditions such as strong winds and blizzards, the roof tiles lack effective wind pressure buffering and snow removal structures, which often lead to problems such as tile lifting, loose connection parts, structural deformation, and snow accumulation that is difficult to remove, resulting in roof leakage and icicles hanging, which bring safety hazards and seriously affect the structural safety and service life of ancient buildings. Although there are ways to set tile pressure strips and windproof nails in the prior art to prevent the roof from being damaged, the existing technology has not been able to solve the problem of roof tiles being damaged or sluggish. Passive reinforcement, but cannot cope with frequent and irregular wind pressure disturbances, and lacks an active drainage structure linked to the airflow. Especially in terms of snow clearing, most of them still rely on manual maintenance, which is labor-intensive, inconvenient to operate, and easy to damage the original roof components. It cannot adapt to the requirements of ancient building maintenance for structural concealment, reversibility and ductility.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element. The term "more than two" includes two or more than two.

[0030] Please refer to Figures 1 to 9 , an anti-wind support device for the ancient building sleeping eaves board 40 provided in the embodiment of the present application includes the outermost roofing tiles 10 and the waterproof board 20 located below the roofing tiles 10, and further includes: an eaves board 30, a sleeping eaves board 40, a drive channel 50 and a vibration limiting member 60;

[0031] The top end of the eaves board 30 is fixedly connected to the roof tile 10, the bottom end of the eaves board 30 does not contact the waterproof board 20, and a plurality of rotating baffles 35 are also arranged on the eaves board 30; the sleeping eaves board 40 can be vertically lifted and clamped above the waterproof board 20 and is located inside the eaves board 30. The vertical part of the sleeping eaves board 40 can be elastically reset, and the vertical part of the sleeping eaves board 40 can abut against the flipped eaves board 30 to limit the flipping of the eaves board 30 and the roof tile 10. The top end of the sleeping eaves board 40 abuts against the lower part of the roof tile 10; the vibration limiting member 60 penetrates through the waterproof board 20 and is connected to the bottom end of the sleeping eaves board 40 to limit the lifting and shaking range of the sleeping eaves board 40; the driving flow channel 50 is arranged below the lifted sleeping eaves board 40 and in the gap between the eaves board 30 and the waterproof board 20; wherein, when the air flow flows from the eaves board 30 towards the sleeping eaves board 40, the rotating baffle 35 can be opened to reduce the force on the roof tile 10. When the air flow flows from the sleeping eaves board 40 towards the eaves board 30, the driving flow channel 50 is in an open state, and the sleeping eaves board 40 can push the roof tile 10 to shake up and down to remove the snow or icicles accumulated on the roof tile 10.

[0032] The anti-wind support device for the sleeping eaves board of the ancient building maintains the overall structural stability in a static wind state. The eaves board 30 fits and closes between the roof tile 10 and the waterproof board 20, maintaining the appearance and integrity of the traditional building without affecting the visual sense and the rainwater drainage function. In the case of wind, the external air flow is introduced into the area of the eaves board 30 through the edge of the roof tile 10. Under the action of the positive air flow, the rotating baffle 35 arranged on the eaves board 30 is pushed open by the air pressure to form a wind-dispersing and pressure-relieving channel. The roof tile 10 is allowed to slightly lift due to the structural design, so as to achieve overall buffering, relieve the tensile stress burden of the fastening screws at the connection part under the irregular wind pressure, and reduce the risks of loosening and fatigue. During the flipping process of the eaves board 30, its bottom end is limited and abutted by the vertical part of the sleeping eaves board 40 to avoid excessive opening causing structural misalignment. The sleeping eaves board 40 maintains vertical mobility by being clamped with the waterproof board 20, and the vibration limiting member 60 connected to its bottom penetrates through the waterproof board 20 to ensure that the amplitude of the sleeping eaves board 40 during the up and down movement caused by the wind is limited, preventing structural interference or derailment. In the case of snow or icicle accumulation, the self-cleaning function can be started by the reverse air guiding method, that is, using the air flow from the sleeping eaves board 40 towards the eaves board 30 to form an organized upward air flow in the driving flow channel 50. This air flow generates periodic disturbances on the lower surface of the sleeping eaves board 40, causing the sleeping eaves board 40 to shake up and down. Then, through the contact between the top end and the bottom edge of the roof tile 10, the vibration is transmitted to the roof tile 10, making it vibrate synchronously, effectively shedding the surface snow layer and icicles, enhancing the winter safety performance of the ancient building and extending the service life of the tiles.

[0033] Such as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, in some examples, further, the roofing tile 10 is provided with a front fixing member 11 and a rear connecting member 12. The front fixing member 11 is fixedly arranged on the front side of the bottom end of the roofing tile 10. The front fixing member 11 is fixedly connected to the top end of the eaves board 30. A fixed abutting position is further arranged on the bottom end of the front fixing member 11. The top end of the eaves board 40 abuts within the abutting position. The rear connecting member 12 is fixedly arranged on the rear side of the bottom end of the roofing tile 10. The rear connecting member 12 is used to provide a rotating position for the roofing tile 10.

[0034] In further structural optimization, by arranging the front fixing member 11 and the rear connecting member 12 on the roofing tile 10, the control of the force conduction path and the restriction of the rotation behavior of the roofing tile 10 are realized. The front fixing member 11 is arranged on the front side of the bottom end of the roofing tile 10. It forms a fixed connection with the top end of the eaves board 30, constructing a starting fulcrum for the rotation of the front part of the roofing tile 10. And an abutting position is arranged at its bottom end. The top end of the eaves board 40 just abuts inside the abutting position in the normal structural state, forming a closed and stable triangular support relationship, so as to provide reverse support when the roofing tile 10 is lifted during wind pressure or airflow disturbance, preventing structural loosening or abnormal warping. The rear connecting member 12 is arranged on the rear side of the bottom end of the roofing tile 10, constituting a limiting mechanism for the controllable rotation of the roofing tile 10. Under the action of wind or airflow, it allows the roofing tile 10 to swing up and down at a small angle around the front fixing member 11, releasing the wind load impact. At the same time, it ensures that when the airflow passes through the driving channel 50 in the reverse direction to push the eaves board 40 to move up and down, the roofing tile 10 can generate local vibration accordingly, accelerating the snow and ice shedding rate, and improving the structural adaptability and operation stability of the ancient building roofing system in extreme climates.

[0035] As Figure 1 、 Figure 2 and Figure 4 shown, in some examples, further, the waterproof board 20 is provided with purlins 21, two support seats 22, at least one hollow hole 23 and a wind blocking board 24. The purlins 21 are fixedly arranged on the top end of the waterproof board 20. The two support seats 22 are arranged on the purlins 21 at intervals. The top ends of the two support seats 22 are respectively rotatably connected to both ends of the rear connecting member 12. At least one hollow hole 23 is opened on the waterproof board 20 between the front fixing member 11 and the rear connecting member 12. The wind blocking board 24 is arranged below the hollow hole 23 in a manner that can be opened and closed.

[0036] In the further structural arrangement, the waterproof board 20 serves as the bearing foundation of the entire roof system. By integrating the rafters 21, the support seats 22, the hollow holes 23 and the wind-blocking plates 24, the multiple functions of the rotation support, airflow control and internal structure protection of the roof tile 10 are realized. The rafters 21 are fixedly arranged at the top of the waterproof board 20, and serve as the main load-bearing components of the roof tile 10 and its auxiliary structures, providing a stable lateral bearing platform. The two support seats 22 are installed on the rafters 21 and maintain a certain distance. The top ends thereof are respectively rotatably connected to the two ends of the rear connecting member 12 at the bottom of the roof tile 10, forming a hinge point for the controllable rotation of the rear side of the roof tile 10, so that the roof tile 10 can change its angle with the front fixing member 11 as the fulcrum under the action of wind pressure, thereby enhancing the buffering response ability of the roof tile 10. At least one hollow hole 23 is provided between the front fixing part 11 and the rear connecting part 12 of the waterproof board 20. The hole is located in the key area of the airflow channel 42, taking into account the structural opening and air pressure guiding functions, so that the airflow can pass through the lower structure of the roof system under two wind directions, and cooperate with the driving flow channel 50 to cause the eaves board 40 to vibrate. An openable wind blocking plate 24 is provided below the hollow hole 23 to form a valve structure with airflow regulation capability. It is kept closed under normal conditions. When it is necessary to clean the snow and icicles on the roof tiles 10, it can be opened when the reverse wind flow is introduced to expand the air inlet area, guide the airflow to enter and flow in the reverse direction, thereby enhancing the linkage effect of the airflow driving the eaves board 40 to vibrate and the roof tiles 10 to slightly lift, and improving the wind resistance, snow discharge and structural stability capabilities of the entire ancient building roof.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in some examples, further, the eaves board 30 is also provided with: a connecting piece 31, a plate body 32, a one-way buckle end 33 and a lace 34, the connecting piece 31 is fixedly connected to the bottom end of the front fixing member 11 by screws; the plate body 32 is fixedly connected to the bottom of the connecting piece 31; the one-way buckle end 33 is fixedly connected to the bottom end of the plate body 32, and the one-way buckle end 33 is spaced above the waterproof board 20 to form a driving flow channel 50 path; the lace 34 is fixedly arranged in a vertical state at the bottom end of the one-way buckle end 33 and is located on the outside of the plate body 32.

[0038] In this implementation structure, the eaves board 30 further constructs a composite module that integrates air flow guidance, structural reinforcement, and aesthetics through an integrated connecting piece 31, a board body 32, a one-way fastening end 33, and a lace 34. The connecting piece 31 is fixedly installed at the bottom end of the front fixing piece 11 by screws and serves as an intermediate connecting bridge between the board body 32 and the eaves board 30, enabling the board body 32 to stably extend to the lower region of the eaves board 30 structurally. A plurality of one-way fastening ends 33 are connected to the lower end of the board body 32. The one-way fastening ends 33 are spaced above the waterproof board 20, forming an intermittent flow channel gap therebetween. The semi-surrounding posture of the one-way fastening board on the upper half of the waterproof board 20 enables the one-way fastening board to rotate slightly upward following the roof tile 10. The one-way fastening board and the waterproof board 20 are spaced apart to construct a complete driving flow channel 50. When the air flow enters the structure in the reverse direction from the direction of the dormer eaves board 40, it can finally pass through the one-way fastening ends 33 to form an orderly channel, enhancing the flow guiding property and kinetic energy release effect. On the one hand, this structure can effectively drive the dormer eaves board 40 to vibrate, and on the other hand, it realizes air flow control to prevent external air flow from interfering with the internal structure operation randomly. The lace 34 is arranged on the outer side of the bottom of the one-way fastening end 33 and is in an overall vertical state. On the one hand, it forms a decorative edge, which is coordinated with the overall style of the ancient building. On the other hand, through its vertical baffle function, it restricts the dissipation of air flow, helps to improve the sealing property of the driving flow channel 50 and the pressure difference formation efficiency, and enhances the response performance and external appearance unity of the entire device in strong wind or ice and snow weather.

[0039] As Figure 4 , Figure 5 , Figure 7 and Figure 8 shown, in some examples, furthermore, a plurality of strip-shaped through holes are provided on the eaves board 30, and there are also provided: a rotating baffle 35 and a force applying member 36. The rotating baffle 35 is rotatably arranged inside the strip-shaped through hole, and the rotating baffle 35 maintains a closed posture in the default state; the force applying member 36 is sleeved on the outer side of the edge of the dormer eaves board 40, and the force applying member 36 includes at least one roller, and the roller abuts against the outer wall of the vertical part of the dormer eaves board 40.

[0040] In this example, the functions of air flow regulation and structural stress conduction and control are realized through the strip-shaped through holes on the eaves board 30, the rotating baffle 35, and the force application member 36 arranged on the outer side of the eaves board 40. Specifically, a plurality of strip-shaped through holes are provided on the eaves board 30, and a baffle that can rotate around an axis is arranged inside the through holes. The rotating baffle 35 remains closed in the default windless state, and fits against the inner wall of the through hole by its own gravity or elastic structure to form a sealing interface to block the direct penetration of air flow. When the forward wind flow impacts the surface of the eaves board 30, the air pressure acts on the inner side of the baffle. When the wind force is large enough, it drives the tile to turn inward around the rotating shaft. After turning, it drives the entire eaves board 30 to move, and the plurality of rotating baffles 35 in the eaves board 30 open to form a ventilation and pressure relief window, avoiding excessive impact loads caused by local accumulation of wind force between the tile and the eaves board 30, and at the same time guiding the evacuation of part of the air flow.

[0041] A force application member 36 is sleeved on the outer side of the edge of the eaves board 40. At least one roller is configured in the force application member 36. The roller remains in close contact with the outer wall of the vertical part of the eaves board 40. During the process of the eaves board 30 and the roof tile 10 being slightly turned upward under force, the roller plays a role of guiding support and surface limit, ensuring that the eaves board 30 is restricted by the vertical position of the eaves board 40 during turning. A flexible damping is formed through the friction and reaction force between the roller and the vertical outer wall to limit vibration and the upward turning amplitude, and improve the service life of the structure.

[0042] As Figure 5 and Figure 6 shown, in some examples, further, the eaves board 40 includes: a bottom plate 41, a plurality of air flow channels 42, a longitudinal plate 44, a middle beam body 45, and a support end 48. The bottom plate 41 is attached to the top end face of the waterproof board 20, and the top end of the vibration limit member 60 is fixed to the bottom plate 41; a plurality of air flow channels 42 are opened on the bottom single end face of the bottom plate 41, and the air flow channels 42 are opened along the eaves board 40 towards the eaves board 30; the longitudinal plate 44 is fixedly connected to the top end of the bottom plate 41 and is located on one side of the eaves board 30. A plurality of longitudinal strip-shaped through holes are opened in the middle of the longitudinal plate 44 for allowing air flow to enter the hollow hole 23; the middle beam body 45 is arranged at equal intervals in the strip-shaped through holes of the longitudinal plate 44; the top of the support end 48 is in an arc shape, and the support end 48 is fixedly arranged at the top end of the longitudinal plate 44.

[0043] In this example, a multifunctional eaves board 40 module with airflow guidance, structural support and tile shaking conduction capabilities is constructed by integrating the bottom plate 41, the airflow channel 42, the longitudinal plate 44, the middle beam 45 and the support end 48. The bottom plate 41 is used as the basic component of the eaves board 40. Its bottom surface is attached to the top end surface of the waterproof board 20 to ensure that the overall structure is firmly embedded. After being lifted, it can be used as the entrance of the driving flow channel 50. Multiple airflow channels 42 pass through the bottom plate 41 from back to front to form a continuous path for guiding the airflow from one side of the eaves board 40 to the side of the sealing eaves board 30, which is used to generate shaking force when the wind reverses and cooperates with the wind cutting. The top of the vibration limiter 60 is fixed to the middle of the bottom plate 41 structure, and the vertical amplitude of the eaves board 40 is limited by structural constraints to prevent separation or interference caused by excessive vibration. A plurality of vertically arranged strip through holes are opened in the middle of the longitudinal plate 44 to further guide the airflow entering from the rotating baffle 35 when the wind pressure is large. The middle beam 45 serves as an equidistant reinforcement member in the through hole, which enhances the overall rigidity of the longitudinal plate 44 and improves the rotation limiting strength of the longitudinal plate 44 on the fascia plate 30. The top of the longitudinal plate 44 is fixedly installed with a support end 48, and the top surface of the support end 48 is an arc-shaped structure, which is used to provide a flexible support contact interface during the flipping process of the fascia plate 30, so that a transition buffer is formed when flipping to the extreme position, avoiding hard impact of the structure edge, and improving the reset stability of the fascia plate 30 and the overall anti-fatigue performance of the device.

[0044] In further structural configuration, through the vertical contact and coordination between the eaves board 40 and the fascia board 30, the flipping path of the roof tile 10 under the action of wind is effectively restricted and buffered, ensuring that the roof tile 10 is always in a controlled state during the arc movement. Since the roof tile 10 rotates in an arc trajectory when it is lifted by the wind, the front end is connected to the fascia board 30 and begins to tilt upward, and the fascia board 30 flips and moves inward, making contact with the vertical part of the eaves board 40. This contact surface forms a vertical deformation resistance during the continuous lifting of the roof tile 10. The eaves board 40 generates a continuous reaction force on the fascia board 30 through its own elastic structure, constructing a gradually increasing reset resistance field. As the flipping angle of the roof tile 10 increases, the higher the height to which it pushes the fascia board 30 to rise, the greater the elastic deformation of the fascia board 40 in contact with it, and the reverse supporting force provided is also enhanced accordingly, so that the fascia board 30 is subjected to a stronger rebound force to limit its continued flipping, thereby forming a step-by-step buffering effect, and ultimately achieving the coordinated operation of path control, improved structural stability and smooth airflow when the roof tile 10 is flipped by the wind.

[0045] like Figure 3 , Figure 5 and Figure 6As shown, in some examples, further, the eaves soffit plate 40 further includes: a guiding plate 43, at least one damping support 46, and a plurality of connecting and strengthening plates 47. The guiding plate 43 is fixedly arranged at one end of the bottom plate 41 away from the fascia board 30, and is in an upwardly warped state at the farthest end from the fascia board 30, forming a guiding area for air flow to enter the driving channel 50; at least one damping support 46 is rotatably arranged between the bottom plate 41 and the longitudinal plate 44; a plurality of connecting and strengthening plates 47 are fixedly connected between the telescopic ends of the two damping supports 46, and the middle parts of the plurality of connecting and strengthening plates 47 are connected to the middle beam body 45.

[0046] In this example, by providing the guiding plate 43, the damping support 46 and the connecting and strengthening plates 47, the collaborative functions of the eaves soffit plate 40 in terms of air flow driving, self-resetting control and structural stability are further enhanced. The guiding plate 43 is installed at one end of the bottom plate 41 away from the fascia board 30, and extends in an upwardly warped angle towards the direction of the rafter 21, forming a low-pressure induction area. During the process of external air flow flowing from the eaves soffit plate 40 to the fascia board 30, the guiding plate 43 changes the air flow entry angle and streamline distribution, making the air flow more stable and concentrated and flowing into the plurality of air channels 42 below the bottom plate 41, thereby enhancing the starting pressure and pneumatic efficiency of the driving channel 50. At least one rotatable damping support 46 is installed between the bottom plate 41 and the longitudinal plate 44. When the fascia board 30 and the tiles are lifted externally, the support generates elastic deformation, and at the same time provides flexible support and motion damping, adjusts the vibration frequency and amplitude, and prevents the structure from becoming unstable or suffering from fatigue cracking due to excessive air flow excitation. A plurality of connecting and strengthening plates 47 are arranged between the two damping supports 46, which play a role in restricting the distance between the damping supports 46, transmitting displacement and coordinating motion. The central area thereof is connected to the middle beam body 45 in the middle strip-shaped through hole of the longitudinal plate 44, forming a linkage framework, so that the vibration energy is evenly distributed among the longitudinal plate 44, the damping structure and the connecting plate, and the response consistency and durability of the overall structure are improved.

[0047] As Figure 6 shown, in some examples, further, the vibration limiting member 60 includes: an adjusting bolt 61, at least two rod bodies 62, and a limiting end block 63. At least two rod bodies 62 can movably penetrate through the bottom plate 41 and the waterproof plate 20; the adjusting bolt 61 is screwed to the top end of the rod body 62 and is located at the top end of the bottom plate 41; the limiting end block 63 is fixedly arranged at the bottom end of the rod body 62.

[0048] In this example, by adjusting the cooperation of the adjusting bolt 61, the movable rod body 62 and the limiting end block 63, the adjustable limitation of the vertical vibration amplitude of the sleep eave board 40 and the enhancement of the structural stability are realized. At least two rod bodies 62 vertically penetrate between the bottom plate 41 of the sleep eave board 40 and the lower waterproof board 20 and maintain the axial movement ability. During the working process, when the sleep eave board 40 vibrates up and down under the excitation of the air flow, the limiting end block 63 provides a fixed anchor point, and the adjusting bolt 61 serves as the upper limit constraint surface, constructing an upper and lower double limiting structure, effectively restraining the structural impact or interference caused by the excessive amplitude of the sleep eave board 40, ensuring that the vibration feedback is orderly and controllable, and improving the durability and anti-fatigue performance of the overall system.

[0049] Working principle:

[0050] The wind-proof support device for the sleep eave board 40 of this ancient building realizes the functions of flexible buffering, pressure relief and snow self-cleaning when the wind force is large through the coordinated cooperation of structures such as the roof tile 10, the eaves board 30, the sleep eave board 40, the waterproof board 20 and the drive channel 50; when the external wind pressure rises, the air flow is introduced from the edge of the roof tile 10, and a plurality of strip-shaped through holes provided on the eaves board 30 are pushed by the high-pressure air flow to open the internal rotating baffle 35, so that part of the air volume is discharged into the cavity between the eaves board 30 and the sleep eave board 40 along the way. Through the front fulcrum formed by the rotating structure and the front fixing piece 11, the roof tile 10 can perform a small-amplitude arc-shaped flip around the rear connecting piece 12 provided on the waterproof board 20. During the flipping process, the bottom end of the eaves board 30 forms a buffer contact with the vertical part of the sleep eave board 40. As the lifting angle increases, the sleep eave board 40 provides an increasingly enhanced reverse supporting force due to its elastic reset ability, constituting a flexible limit response to prevent the roof tile 10 from being structurally displaced or the screws from loosening due to excessive wind force. In the reverse snow-clearing mode, the wind-blocking plate 24 is manually opened actively, and the air flow reversely flows in from below the hollow hole 23 of the waterproof board 20, guiding the wind to enter from one side of the sleep eave board 40 into the air flow channels 42 provided on a plurality of bottom plates 41, and passing through along the direction of the drive channel 50. Finally, a strong guiding air flow is formed between the one-way buckling end 33 and the eaves board 30. This air flow flows through the bottom of the sleep eave board 40, causing the sleep eave board 40 to vibrate up and down rhythmically, and further transmitting the impact to the lower edge of the roof tile 10, thereby causing the roof tile 10 to vibrate slightly, making the snow and icicles attached to its surface lose stability and slide off, realizing the self-cleaning function of the roof without manual intervention, and comprehensively improving the adaptability, safety performance and structural service life of the ancient building roof under complex climate conditions.

For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
