Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a fireproof partition and a combined suspended ceiling. Background Technology
[0002] Fire-resistant partitions are structures used to prevent the spread of fire to adjacent areas during a fire. Existing fire-resistant partitions in indoor passageways mainly include fire doors and fire-resistant roller shutters. Fire doors open in the direction of evacuation and must have self-closing and smoke-proof functions. Fire-resistant roller shutters are mainly used to separate passageways from atriums, escalators, large open spaces, and other openings to ensure the formation of closed fire-resistant zones in the event of a fire.
[0003] Fire-resistant roller shutters require sufficient installation height to ensure they can be fully lowered to form an effective fire compartment. If the building has a low ceiling or limited space above openings, fire-resistant roller shutters may not be able to be installed. Furthermore, in densely populated areas such as shopping malls and warehouses, if the roller shutter is obstructed during descent, it cannot form a complete fire compartment, thus losing its fire-resistant function. Roller shutters that have not been used for a long time may malfunction due to dust accumulation on the tracks, rust on the motor, or deformation of the curtain slats, resulting in improper opening and closing, reduced overall height due to obstructed passageway height, and negatively impacting the interior space's aesthetics and comfort.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0054] The following is combined with Figures 1 to 4 The fireproof partition and combined ceiling provided by the present invention will be described in detail through specific embodiments and application scenarios.
[0055] Firstly, such as Figure 1 and Figure 3 As shown, this embodiment provides a fireproof partition 1, including: a fixed bracket 11 and a fireproof board 12.
[0056] The fixed bracket 11 includes a main keel 111 and a secondary keel 112. Multiple main keels 111 and multiple secondary keels 112 are provided. Multiple main keels 111 are used to be installed side by side on the top surface of the indoor passage, and multiple secondary keels 112 are installed side by side on the main keel 111.
[0057] One end of the fireproof board 12 is rotatably mounted on the main keel 111 to switch between a first position P and a second position N.
[0058] When the indoor passage is closed, the fireproof board 12 rotates to the first position P, which is perpendicular to the main keel 111, and the fireproof board 12 closes the indoor passage.
[0059] With the indoor passageway open, the fireproof board 12 rotates to a second position N parallel to the fixed bracket 11 and is housed under the fixed bracket 11.
[0060] Understandably, in this embodiment, the main keel 111 is arranged in parallel intervals and is suspended from the top surface of the indoor passageway by hangers. The secondary keel 112 is arranged perpendicularly to the main keel 111, and the overlaps of the secondary keel 112 and the main keel 111 are fixedly connected. Multiple main keels 111 and multiple secondary keels 112 form a three-dimensional suspension structure, which can stably support the rotation of the fireproof board 12 between the first position P and the second position N. Furthermore, the arrangement of the main keels 111 and secondary keels 112 can be flexibly adjusted according to the characteristics of the building's interior space, adapting to interior spaces with different building structures and improving the versatility of the fireproof partition 1.
[0061] When the interior is in its normal state, the interior passageway is open, and the fireproof board 12 is in the second position N, housed as a regular suspended ceiling under the fixed bracket 11, and integrated with the surrounding suspended ceiling units 2, ensuring overall aesthetics. Furthermore, the fireproof board 12 and the main keel 111 and secondary keel 112 of the fixed bracket 11 are all embedded within the suspended ceiling space, occupying minimal space. The overall thickness of the fireproof partition 1 is also relatively small, maximizing the preservation of floor height, making it particularly suitable for space-constrained renovation projects and low-ceiling projects such as underground spaces.
[0062] In case of an emergency such as a fire indoors, a fireproof partition 1 is needed to close the indoor passageway to prevent the fire from spreading. The fireproof panel 12 rotates from the second position N to the first position P, changing from its concealed state to a position perpendicular to the main keel 111, thus sealing the indoor passageway. Compared to fire doors and fireproof roller shutters, which require space to open and close and require storage boxes, the fireproof panel 12 of this application is normally concealed under the fixed bracket 11 as part of the ceiling, integrating into the indoor space. In the event of a fire, it can rotate to a position perpendicular to the passageway, thus blocking the indoor passageway.
[0063] The fireproof partition 1 provided by this utility model, by setting main keel 111 and secondary keel 112 on the fixed bracket 11, and by installing multiple main keels 111 and multiple secondary keels 112 side by side and in an alternating manner, adapts to different building interior environments. The fireproof board 12 is rotatably set on the fixed bracket 11. In normal state, the fireproof board 12 is rotated to a position parallel to the fixed bracket 11 and housed under the fixed bracket 11 for use as a ceiling. In the event of a fire, the fireproof board 12 is rotated to a position perpendicular to the main keel 111, closing the interior passage and isolating the interior passage to prevent the spread of fire. Since the main keel 111, secondary keel 112 and fireproof board 12 are all embedded in the ceiling, they occupy little space, maximize the preservation of floor height, and can close the interior passage in the event of a fire. This realizes the flexible switching between ceiling function and fireproof function, and achieves the effect of forming an effective fireproof partition in a narrow passage with low floor height.
[0064] like Figure 1 As shown, the fixed bracket 11 in this embodiment also includes a housing 113 and a rotating shaft 114.
[0065] The enclosure 113 is located on one of the main keels 111 closest to the fireproof board 12. The length of the enclosure 113 extends along the length of the main keel 111, and the enclosure 113 has a hollow inner cavity.
[0066] The rotating shaft 114 is rotatably disposed in the inner cavity and is connected to one end of the fireproof board 12 near the top surface of the indoor passage.
[0067] Understandably, the pivot 114 can drive the fireproof board 12 to rotate between the first position P and the second position N. The housing 113 can accommodate the pivot 114, ensuring an overall uniform appearance. The fireproof board 12 and the housing 113 rotate via the pivot 114, which realizes the rotation function of the fireproof board 12 without increasing the space occupied, and the structure is simple and easy to install.
[0068] Since the fireproof board 12 can fall by gravity without the need for additional drive equipment, it does not need to rely on electricity or backup power. In the event of a fire, it falls rapidly by its own weight to form a fire barrier, avoiding the failure of drive equipment due to power outages or mechanical failures, and has a better response to fire.
[0069] Specifically, the rotating shaft 114 is provided with a limiting structure, so that the fireproof board 12 can only rotate between the first position P and the second position N, with a rotation angle of 90°.
[0070] like Figure 1 As shown, the fireproof partition 1 in this embodiment also includes: an elastic traction belt 13.
[0071] The first end of the elastic traction belt 13 is connected to the box 113, and the second end of the elastic traction belt 13 is wrapped around the top surface of the fixed bracket 11 and connected to the end of the fireproof board 12 away from the box 113.
[0072] Understandably, to ensure the stability of the fireproof board 12's rotation, this embodiment includes an elastic traction belt 13. The elastic traction belt 13 wraps around the top of the fixed bracket 11 and connects to the fireproof board 12. During the rotation of the fireproof board 12, the elastic traction belt 13, capable of extending and shortening, provides rotational damping, slowing down the rotation speed of the fireproof board 12. Furthermore, when the fireproof board 12 is housed under the fixed bracket 11, the elastic traction belt 13 can also secure the end of the fireproof board 12 away from the housing 113, making the housing state of the fireproof board 12 more reliable.
[0073] like Figure 1 As shown, the fireproof partition 1 in this embodiment also includes a guide component 14.
[0074] The guide assembly 14 is provided on the housing 113; when the fireproof plate 12 rotates from the second position N to the first position P, the guide assembly 14 is used to guide the second end of the elastic traction belt 13 to move from the second position N to the first position P.
[0075] Understandably, to prevent the elastic traction belt 13 from swaying due to factors such as airflow during its descent, this embodiment includes a guide assembly 14. The guide assembly 14 guides the movement of the second end of the elastic traction belt 13 as the fireproof plate 12 rotates from the second position N to the first position P, ensuring that the elastic traction belt 13 is not subjected to any external forces other than the reaction force of the fireproof plate 12. This restricts the movement path of the elastic traction belt 13 during the rotation of the fireproof plate 12, thereby ensuring the stability of the elastic traction belt 13.
[0076] like Figure 1 and Figure 2 As shown, the guide assembly 14 in this embodiment includes a guide frame 141 and a guide wheel 142.
[0077] The first end of the guide frame 141 is rotatably disposed on the housing 113 and located between the fireproof plate 12 and the fixed bracket 11. The guide frame 141 has a limiting hole 14121.
[0078] The guide wheel 142 is rotatably mounted on the second end of the guide frame 141 and is positioned toward the limiting hole 14121. The elastic traction belt 13 passes through the limiting hole 14121 and rotates in contact with the guide wheel 142.
[0079] Understandably, the guide frame 141 is positioned between the fireproof plate 12 and the housing 113. When the fireproof plate 12 rotates, the guide frame 141 rotates accordingly, with a rotation angle of 0° to 45°. The guide wheel 142 can rotate relative to the guide frame 141, allowing the elastic traction belt 13 to pass through the limiting hole 14121 and abut against the guide wheel 142. As the elastic traction belt 13 is pulled, the guide wheel 142 rotates accordingly. The two sides of the elastic traction belt 13 are constrained within the limiting hole 14121, preventing it from swaying left or right. Furthermore, due to the sliding contact between the guide wheel 142 and the elastic traction belt 13, the traction effect of the elastic traction belt 13 is not affected, thus achieving a good guiding effect for the elastic traction belt 13.
[0080] like Figure 1 and Figure 2 As shown, in this embodiment, there are two elastic traction straps 13, which are respectively located on both sides of the fireproof board 12.
[0081] The guide frame 141 includes a first frame 1411 located in the middle and a second frame 1412 located on both sides of the first frame 1411. The second frame 1412 has a limiting hole 14121.
[0082] Two guide wheels 142 are also provided, and the two guide wheels 142 are respectively located on the two second frames 1412. Each elastic traction belt 13 is arranged opposite to each guide wheel 142.
[0083] Understandably, in order to ensure the balance of force on the fireproof board 12, the elastic traction belt 13 in this embodiment is provided with two belts.
[0084] Accordingly, each elastic traction belt 13 is provided with a corresponding limiting hole 14121 and a guide wheel 142. In this embodiment, the first frame 1411 of the guide frame 141 is located in the middle to support and hold the two second frames 1412 located on both sides. The first frame 1411 is provided with two intersecting reinforcing ribs to reinforce the overall structure. The second frame 1412 has a strip-shaped limiting hole 14121 and a guide wheel 142 is provided at the end of the second frame 1412 facing the ground. The two guide wheels 142 respectively rotate into contact with the corresponding elastic traction belt 13 to guide and limit the elastic traction belt 13 on each side.
[0085] The fireproof partition 1 in this embodiment also includes a switching component.
[0086] The switching component is located at the end of the fireproof board 12 away from the fixed bracket 11, and the fireproof board 12 can be selectively connected to the main keel 111 through the switching component.
[0087] Understandably, in order to ensure that the fireproof board 12 can be stably used as a ceiling when it is in the second position N, this embodiment also includes a switching assembly. Under normal conditions, the switching assembly securely connects the main keel 111 to the fireproof board 12, preventing the fireproof board 12 from detaching. In the event of a fire, the switching assembly separates from the main keel 111, ensuring the normal rotation of the fireproof board 12.
[0088] Specifically, the switching component can be a telescopic protrusion, with a corresponding groove set on the main keel 111. The connection and separation of the fireproof board 12 and the main keel 111 can be achieved by the telescopic protrusion extending and retracting relative to the groove.
[0089] like Figure 1 and Figure 4 As shown, the fireproof partition 1 in this embodiment also includes a chain 15 and a sprocket 16.
[0090] The sprocket 16 is rotatably disposed inside the housing 113, and the chain 15 is wound around the sprocket 16 and connected to the end of the fireproof plate 12 away from the housing 113.
[0091] When the indoor passage is in the open state, the chain 15 is housed in the housing 113; when the indoor passage switches from the closed state to the open state, the chain 15 slides around the sprocket 16 to rotate the fireproof plate 12 to the second position N.
[0092] Understandably, for fireproof partition 1 without power equipment, the fireproof board 12 rotates to the first position P under the action of gravity. After a fire, when it is necessary to rotate the fireproof board 12 back to the second position N, the chain 15 and sprocket 16 can be used to achieve the reset function of the fireproof board 12.
[0093] The sprocket 16 is located inside the housing 113, and the chain 15 is normally stored inside the housing, neither taking up space, and the housing 113's concealment ensures the aesthetics of the space. During the repositioning process of the fireproof plate 12, the worker pulls one end of the chain 15, and under the action of the sprocket 16, the end of the fireproof plate 12 away from the housing 113 rotates toward the fixed bracket 11 until the fireproof plate 12 is reset.
[0094] The fireproof board 12 in this embodiment includes a first metal plate layer, a heat insulation layer, and a second metal plate layer; the heat insulation layer is sandwiched between the first metal plate layer and the second metal plate layer.
[0095] Understandably, the first and second metal plates can prevent the spread of fire, and the insulation layer can isolate the heat generated during a fire.
[0096] Specifically, both the first and second metal plates can be made of galvanized steel, and the insulation layer can be made of rock wool or aluminum silicate limiting layer.
[0097] The fixed bracket 11 in this embodiment includes a fireproof metal part and a fireproof coating; the fireproof coating is applied to the outside of the fireproof metal part.
[0098] Understandably, both the main keel 111 and the secondary keel 112 are made of fire-resistant metal components, which helps maintain shape stability in a fire. Furthermore, a fire-retardant coating is applied to the outer layer of the fire-resistant metal components, further ensuring the fire-resistant function of the fixing bracket 11.
[0099] Secondly, such as Figure 1 and Figure 3 As shown, this embodiment provides a combined ceiling, including: ceiling unit 2 and the fireproof partition 1 as described above.
[0100] Fireproof partition 1 is installed at the opening and closing point of the indoor passage. Multiple ceiling units 2 are provided, and multiple ceiling units 2 are arranged in sequence with fireproof partition 1. The panels of ceiling units 2 and fireproof boards 12 have the same decorative surface layer.
[0101] Specifically, since the combined ceiling includes a fireproof partition 1, and the specific structure of the fireproof partition 1 is as described in the above embodiments, the combined ceiling shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be elaborated here.
[0102] Understandably, fire-resistant partition 1 is installed in indoor passageways where it needs to be separated in the event of a fire. In daily use, fire-resistant partition 1 serves as part of the combined suspended ceiling, acting as the suspended ceiling itself. The combined suspended ceiling adopts a modular layout, with multiple suspended ceiling units 2 and fire-resistant partition 1 all being components of suspended ceiling units 2.
[0103] Specifically, the panels of the ceiling unit 2 and the fireproof board 12 can be fitted with the same decorative surface layer and kept in line with the style of the overall space. This allows the fireproof partition 1 to function as part of the ceiling when not in use, ensuring the overall aesthetics and improving the overall quality of the space.
[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
