Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "connected" and "linked" used in this invention should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0034] According to specific embodiments of the present invention, such as Figure 1-3 As shown, this invention provides a fire-resistant testing device for movable and retractable fireproof eaves on the exterior of high-rise buildings. The testing device includes:

[0035] The simulation features a high-rise building with a track assembly on one side.

[0036] The track assembly includes multiple parallel horizontal slide rails 1 and multiple parallel vertical slide rails 2, with the multiple horizontal slide rails 1 and the multiple vertical slide rails 2 intersecting each other.

[0037] Fireproof eaves assembly, which includes a horizontal eaves 3 and a vertical eaves 4.

[0038] Each horizontal slide rail 1 is provided with a horizontal eave 3, and each vertical slide rail 2 is provided with a vertical eave 4.

[0039] The driving device includes a horizontal driving structure and a vertical driving structure. The horizontal driving structure is used to drive the horizontal eaves 3 to move along the horizontal slide rail 1; the vertical driving structure is used to drive the vertical eaves 4 to move along the vertical slide rail 2.

[0040] In this testing device, multiple horizontal slide rails 1 and vertical slide rails 2 are set on the side of the simulated high-rise building, so that the horizontal eaves 3 on each horizontal slide rail 1 can move along the horizontal slide rail 1 to any horizontal position of the simulated high-rise building; the vertical eaves 4 on each vertical slide rail 2 can move along the vertical slide rail 2 to any vertical position of the simulated high-rise building; then when a fire occurs at any position on the simulated high-rise building, the eaves on the upper, lower, left and right slide rails of the fire point can be adjusted to form a square shape, thereby minimizing the impact of the fire point on the vicinity; that is, the testing device of this application can greatly utilize the flexibility of the fireproof eaves, so that the fireproof eaves have a more suitable and efficient fire-proof function.

[0041] In this embodiment, the horizontal eaves 3 and the vertical eaves 4 are made of carbon fiber reinforced flame-retardant polymer lightweight composite material. In other embodiments, the horizontal eaves 3 and the vertical eaves 4 can also be made of other non-combustible or flame-retardant materials.

[0042] Both the horizontal slide rail 1 and the vertical slide rail 2 have a T-slot structure in cross-section. The ends of the horizontal eaves 3 and vertical eaves 4 that engage with the track assembly are T-shaped, so that the T-shaped end of the horizontal eaves 3 engages in the T-slot of the horizontal slide rail 1, and the T-shaped end of the vertical eaves 4 engages in the T-slot of the vertical slide rail 2. This design prevents the horizontal eaves 3 from detaching from the horizontal slide rail 1 and the vertical eaves 4 from detaching from the vertical slide rail 2, thus ensuring that the fireproof eaves can slide stably within the track assembly.

[0043] In other embodiments, the cross-sections of the horizontal slide rail 1 and the vertical slide rail 2 can also be dovetail grooves. In this case, one end of the horizontal eaves 3 and the vertical eaves 4 that are engaged in the track assembly is a dovetail end, so that the dovetail end of the horizontal eaves 3 is engaged in the dovetail groove of the horizontal slide rail 1, and the dovetail end of the vertical eaves 4 is engaged in the dovetail groove of the vertical slide rail 2.

[0044] The horizontal slide rail 1 and the vertical slide rail 2 are in the same plane. At the intersection of the horizontal slide rail 1 and the vertical slide rail 2, the T-slot of the horizontal slide rail 1 and the T-slot of the vertical slide rail 2 are interconnected. This ensures that the horizontal eaves 3 and the vertical eaves 4 can move to any position along the corresponding slide rails without interference.

[0045] Both the horizontal and vertical drive structures are winches. The connecting rope on the winch is connected to the fireproof eaves assembly so that the winch can pull the fireproof eaves assembly to move on the track assembly.

[0046] A winch is set at one end of the horizontal slide rail 1 and a horizontal eave 3 is set at the other end. The connecting rope in the winch is connected to the horizontal eave 3 to drive the horizontal eave 3 to move on the horizontal slide rail 1.

[0047] A winch is installed at the top of the vertical slide rail 2. A vertical cantilever 4 is connected to the connecting rope of the winch. The vertical cantilever 4 is installed close to the winch at the top of the vertical slide rail 2.

[0048] In this embodiment, the horizontal eaves 3 on the horizontal slide rail 1 are first moved into place, and then the vertical eaves 4 on the vertical slide rail 2 are lowered to the corresponding position. This arrangement can avoid interference between the connecting rope of the horizontal winch and the connecting rope of the vertical winch.

[0049] A bottom winch 6 is set at one corner of the bottom of the track assembly. A horizontal cantilever 3 is set at one end of each horizontal slide rail 1 away from the bottom winch 6. A fixed pulley 7 is set at the other end of the horizontal slide rail 1. A drive rope is connected to each horizontal cantilever 3. The drive rope passes around the fixed pulley 7 at the end of the horizontal slide rail 1 and extends to the vicinity of the winch at the bottom.

[0050] In use, the drive rope on the horizontal eaves 3 on the horizontal slide rail 1 that needs to be moved is connected to the winch, and the bottom winch 6 drives the movement. In addition, the drive ropes of at least two horizontal eaves 3 on the horizontal slide rail 1 can be connected to the bottom winch 6 at the same time, so that the bottom winch 6 can drive at least two horizontal eaves 3 to move at the same time, which can greatly improve the efficiency of the movement of the horizontal eaves 3 and is more conducive to suppressing the spread of fire.

[0051] A top winch 5 is set at one corner of the top of the track assembly. A vertical cantilever 4 is set on the upper part of each vertical slide rail 2. A fixed pulley 7 is set at the top of each vertical slide rail 2. A drive rope is connected to each vertical cantilever 4. The drive rope passes around the fixed pulley 7 at the top of the vertical slide rail 2 and extends to the vicinity of the top winch 5.

[0052] In this embodiment, the drive ropes on all vertical eaves 4 can be simultaneously connected to the top winch 5, so that the top winch 5 drives the vertical eaves 4 to move down to the same height as the fire point in the simulated high-rise building, thereby preventing the fire point from spreading within the same floor. It should be noted that, in order to avoid interference between the drive ropes of the vertical eaves 4 and the horizontal eaves 3, the horizontal eaves 3 are moved first, and then the vertical eaves 4 are lowered.

[0053] In addition, the top winch 5 and the bottom winch 6 can be directly fixed to the exterior wall of the simulated high-rise building.

[0054] In other embodiments, a fixed rod can be set next to the top winch 5. First, the drive ropes on all the vertical eaves are fixed to the fixed rod. When it is necessary to move some of the vertical eaves 4, the drive ropes on these vertical eaves 4 are untied from the fixed rod and connected to the top winch 5, so that the top winch 5 can drive the required number of vertical eaves 4 to be lowered to the height of the fire point.

[0055] Both the horizontal eaves 3 and the vertical eaves 4 are retractable structures.

[0056] When there is no fire, the horizontal eaves 3 and the vertical eaves 4 are reduced to their shortest length. When a fire occurs, the horizontal eaves 3 and the vertical eaves 4 are extended to their longest length, so that the horizontal eaves 3 and the vertical eaves 4 can better prevent the fire source and unburned particles from escaping.

[0057] Both the horizontal eaves 3 and the vertical eaves 4 include a mother plate 10 and multiple sub-plates 11 nested within the mother plate 10. The sub-plates 11 located inside the mother plate 10 are guided to move within the mother plate 10. Between any two adjacent mother plates 10 and sub-plates 11, one end is provided with an inwardly protruding retaining edge, and the other end is provided with an outwardly protruding retaining edge, so that any two adjacent mother plates 10 and sub-plates 11 are mutually limited by the retaining edges.

[0058] In this embodiment, the multiple sub-plates 11 are also nested together. Between any two adjacent sub-plates 11, the end of the outer sub-plate 11 is provided with an inwardly protruding retaining edge, and the end of the inner sub-plate 11 is provided with an outwardly protruding retaining edge. The two retaining edges cooperate with each other to prevent the inner sub-plate 11 from coming out of the outer sub-plate 11 after the inner sub-plate 11 extends out.

[0059] Both the mother plate 10 and the daughter plate 11 are hollow structures. A water inlet is provided on the mother plate 10, which is connected to the hollow structure inside the mother plate 10 and the daughter plate 11. The water inlet is connected to the water tank through a water inlet pipe for supplying water to the mother plate 10.

[0060] Water outlets are provided on the sides and / or bottom of the mother plate 10 and the daughter plate 11. When it is necessary to extend the daughter plate 11 out of the mother plate 10, high-pressure water is injected into the mother plate 10 through the water inlet, and the high-pressure water pushes the daughter plate 11 out of the mother plate 10.

[0061] This application uses high-pressure water to directly push the sub-plate 11 out of the mother plate 10. The high-pressure water can both extend the horizontal eaves 3 and the vertical eaves 4, and also give the horizontal eaves 3 and the vertical eaves 4 a certain fire-extinguishing function, achieving two goals at once and greatly improving the utilization efficiency of the fireproof eaves. Specifically, water outlets are provided on the underside of the mother plate 10 and the sub-plate 11 in the horizontal eaves 3, and on the sides of the mother plate 10 and the sub-plate 11 in the vertical eaves 4, thereby achieving a better fire-extinguishing effect. In other embodiments, water outlets can also be provided on the sides and underside of the mother plate 10 and the sub-plate 11.

[0062] In this test device, the water inlet on the fireproof eaves mother plate 10 is directly connected to the water tank through the water inlet pipe; in actual application, the water inlet on the fireproof eaves mother plate 10 can be connected to the water supply pipeline or fire water pipeline on the same floor through the water inlet pipe.

[0063] In other embodiments, a hook may be provided at the front end of the sub-plate 11, and a telescopic rope may be connected to the hook. By pulling the telescopic rope outward, the sub-plate 11 may be pulled out of the mother plate 10.

[0064] In summary, the technical solution of the movable and retractable eaves fire-resistant testing device for high-rise facades provided by this invention allows the eaves on the upper, lower, left, and right sliding rails to move and enclose into a U-shape, thereby minimizing the impact of the fire point on the surrounding area. This enables the testing device to maximize the flexibility of the fire-resistant eaves, resulting in a more suitable and efficient fire-resistant effect. Furthermore, the testing device uses high-pressure water to directly push the sub-panel out of the mother panel. The high-pressure water not only extends both the horizontal and vertical eaves but also gives them a certain fire-extinguishing function, achieving two goals at once and greatly improving the efficiency of the fire-resistant eaves.

[0065] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
