[0054] Embodiment one

[0055] The following will be combined Figures 1-14 The present application provides a multifunctional building eaves structure.

[0056] In this embodiment, a multifunctional building eaves structure is provided, which is applied to a building outer wall 2; the building eaves structure comprises an eaves platform 1 and a rotating plate 3.

[0057] Specifically, the eaves platform 1 is arranged at a first preset angle on the building outer wall 2; the first preset angle herein is preferably 90°, that is, the eaves platform is vertically connected to the outer side of the building outer wall.

[0058] Preferably, in combination Figures 1-4 As shown, the eaves platform 1 is a flat plate structure (the flat plate structure herein can be understood as a one-word structure of the eaves platform 1).

[0059] Preferably, in combination Figures 5-9 As shown, the eaves platform 1 is an L-shaped structure, the L-shaped eaves platform 1 comprises a horizontal plate 18 perpendicular to the building outer wall 2 and a vertical plate 19 perpendicular to the horizontal plate 18 and away from the building outer wall 2, when the eaves platform 1 is an L-shaped structure, one end of the rotating plate 3 is rotatably connected to the end of the vertical plate 19 away from the horizontal plate 18. More preferably, the vertical plate 19 is integrally formed with the horizontal plate 18.

[0060] Specifically, one end of the rotating plate 3 is rotationally connected to the end of the eaves platform 1 away from the building outer wall 2, so that the end of the rotating plate 3 away from the eaves platform can be buckled to or opened from the building outer wall 2; when the rotating plate 3 is opened from the building outer wall 2, the rotating plate 3 is perpendicular to the eaves platform 1 or the horizontal plate 18, and the rotating plate 3 serves as a protective fence, so that the rotating plate, the eaves platform (or the horizontal plate and the vertical plate), and the building outer wall form an escape or maintenance passage.

[0061] In summary, in actual use: in the normal state (initial state), the rotating plate is buckled to the building outer wall; when a fire occurs in the house or the outer wall needs to be maintained, the rotating plate is opened from the building outer wall, i.e., the rotating plate is separated from the building outer wall and is perpendicular to the eaves platform, at which time the rotating plate has the function of a protective fence, so that the rotating plate, the eaves platform, and the building outer wall form a temporary horizontal (horizontal refers to between neighbors on the same floor or between left and right rooms) escape passage, or can be used for a maintenance passage, which is used when maintaining air conditioners, photovoltaic devices, etc. hung on the building outer wall; when the rotating plate does not need to be opened from the building outer wall, the rotating plate is always buckled to the building outer wall, i.e., the rotating plate is buckled to the building outer wall at a certain inclination angle at this time, and such an inclined rotating plate can prevent thieves from entering the house through the window to steal.

[0062] It is worth noting that: (1) In actual use: the eaves platform of the building eaves structure needs to be reinforced (for example, reinforcing bars are provided on the lower side of the eaves platform and close to the side of the building outer wall, one end of the reinforcing bars is fixed to the eaves platform and the other end is fixed to the building outer wall), which meets the load-bearing requirements of the personnel escape or maintenance passage. (2) The rotating plate 3 needs to reach the height required by the building fence during escape or maintenance. (3) The eaves platform 1 can be a cornice, a bracket, an air conditioner platform, a canopy, a protective platform, a protective canopy, etc. in actual use. (4) The eaves platform 1 and the building outer wall 2 can be designed as an integrated structure to enhance the stability of the eaves platform 1; in addition, fixed connecting members can be pre-buried in the building outer wall 2 during construction, and the eaves platform 1 and the rotating plate 3 can be designed as modules and installed as a whole. (5) The rotating plate 3 can be a plate, a frame, a net, or a fence structure, and is a plate structure when combined with power generation or heat collection functions.

[0063] In this embodiment, the rotating plate 3 is combined with a driving member. Figures 1-9 As shown in the figure, the two ends of the driving member are movably connected to the rotating plate and the eaves platform, and the driving member has a driving part and a telescopic part connected to the driving part; the driving part is movably connected to the eaves platform 1, and the telescopic part is movably connected to the rotating plate 3; the driving member can drive the rotating plate to be opened from or buckled to the building outer wall.

[0064] Specifically, the driving member is combined with the rotating plate 3. Figures 1-4As shown, taking the cantilevered platform as a flat structure, with the drive unit connected to the cantilevered platform and the telescopic unit connected to the rotating plate as an example, the following detailed explanation will be given: The drive component is a gas strut, which includes a cylinder 25 (the cylinder 25 serves as the drive unit), a gas spring telescopic rod 23 (the gas spring telescopic rod 23 serves as the telescopic unit), and a gas strut head 24; one end of the gas spring telescopic rod 23 is inserted into the cylinder 25 and can move relative to the cylinder 25, and the other end of the gas spring telescopic rod 23 is movably connected to the rotating plate 3 through the gas strut head 24, and the end of the cylinder 25 away from the gas spring telescopic rod 23 is movably connected to the cantilevered platform 1 through the gas strut head 24.

[0065] Specifically, in combination Figures 5-9 As shown, taking an L-shaped structure of the outer eaves platform, with the drive unit connected to the outer eaves platform and the telescopic unit connected to the rotating plate as an example, a detailed explanation will be given. The drive component is a gas strut, which includes a cylinder 25 (the cylinder 25 serves as the drive unit), a gas spring telescopic rod 23 (the gas spring telescopic rod 23 serves as the telescopic unit), and a gas strut head 24. One end of the gas spring telescopic rod 23 is inserted into the cylinder 25 and can move relative to the cylinder 25. The other end of the gas spring telescopic rod 23 is movably connected to the rotating plate through the gas strut head 24. The end of the cylinder 25 away from the gas spring telescopic rod 23 is movably connected to the horizontal plate 18 through the gas strut head 24.

[0066] Preferably, the gas strut model is TLG-07. More preferably, the gas strut must have the function of unlocking and manually opening / closing in the event of a power outage, that is, the rotating plate 3 can be manually opened even when the power is off.

[0067] It is worth noting that, in addition to the structure described above, the drive component can also adopt the following structure: the drive component 4 can be an electric push rod, and the electric push rod has the function of unlocking and manually opening and closing when the power is off. The electric push rod consists of a drive motor part and a telescopic rod part. The drive motor part of the electric push rod is movably connected to the outer eaves platform 1 (or the horizontal plate 18), and the telescopic rod part is movably connected to the rotating plate 3.

[0068] In this embodiment, combined with Figure 5 , Figure 8 As shown, the building's external eaves structure also includes a locking component; the locking component includes a locking part and a limiting part; the limiting part is located at the end of the rotating plate 3 near the building's external wall 2, and the locking part is located on the building's external wall 2; when the rotating plate 3 is fastened to the building's external wall 2, the locking part can lock onto the limiting part so that the rotating plate 3 can be fixed to the building's external wall 2.

[0069] Preferably, the locking assembly includes a buckle 20 that can serve as a locking part and a slot that can serve as a limiting part (the slot is not shown in the figure, but is understood by those skilled in the art); when the buckle 20 is inserted into the slot, the rotating plate 3 can be stably fixed to the building exterior wall 2.

[0070] In this embodiment, the building's external eaves structure also includes a limiting component, which is used to limit the opening position of the rotating plate 3 when the rotating plate 3 is opened on the building's external wall 2.

[0071] In a preferred embodiment, combining Figure 3 As shown, when the overhanging platform is a plate-shaped structure, the limiting component is a limiting rod 14. The limiting rod 14 ensures that the limiting angle between the rotating plate 3 and the overhanging platform 1 cannot exceed 90 degrees. More preferably, the limiting rod 14 is set vertically at the end of the overhanging platform 1 away from the building's outer wall 2. That is, the limiting rod 14 enables the rotating plate 3 to be perpendicular to the overhanging platform when the rotating plate 3 is opened to the building's outer wall 2, so that it can be used as a guardrail.

[0072] Another preferred option is to combine Figure 5 , Figure 6 As shown, when the overhanging platform is L-shaped, the limiting component is the limiting plate 22. The limiting plate 22 is a part of the rotating plate 3 that extends away from the building's exterior wall. When the rotating plate opens the building's exterior wall, the limiting plate 22 will eventually abut against the vertical plate 19 to form a 90-degree vertical guardrail. The top of the rotating plate 3 is rotatably connected to the top of the vertical plate 19.

[0073] In this embodiment, a spring (not shown in the figure, but understood by those skilled in the art) can be optionally installed between the building's external eaves platform 1 and the rotating plate 3 to facilitate the rapid opening and fixing of the rotating plate 3 when it is opened.

[0074] Example 2

[0075] Combination Figures 12-14 As shown, the building's external eaves structure also includes an escape component 9 disposed below the external eaves platform 1 (or the horizontal plate 18); the escape component 9 is a folding staircase, which includes two fixed connecting rods 5, two movable connecting rods 6, and multiple step stools 7. The two fixed connecting rods 5 extend vertically and are fixed to the building's external wall 2 at intervals in the horizontal direction. The two movable connecting rods 6 are respectively positioned corresponding to the two fixed connecting rods 5. The multiple step stools 7 are disposed at intervals between the fixed connecting rods 5 and the movable connecting rods 6 in the vertical direction; the two ends of the step stools 7 are respectively rotatably connected to the fixed connecting rods 5 and the movable connecting rods 6.

[0076] The overhanging platform 1 (or the horizontal plate 18) has a skylight 8 at the position corresponding to the escape component 9. In the initial state, the movable link 6 is folded to the fixed link 5. In the event of a fire, the skylight 8 is opened, and the movable link 6 is pulled outward from the rotation direction 21 to open the folding ladder. The movable link 6 is used as a handrail, and the foot pedal 7 is used to escape downwards. When not in use, the movable link 6 is pulled back towards the outer wall to close it on the fixed link on the outer wall.

[0077] In summary, once there is a fire, the driving member 4 first opens the rotating plate 3 from the building outer wall 2, so that the rotating plate 3 is used as a protective fence; then the escape member 9 can be opened, and through the escape member 9, one can escape from the floor where the fire occurs to other floors.
