Description

TECHNICAL FIELD

[0001] The utility model relates to an integrated device of a decorative tray and a spray head in a grid ceiling, and belongs to the technical field of grid ceilings. BACKGROUND ART

[0002] In architectural design, when the permeable area of a permeable ceiling accounts for no more than 70% of the total ceiling area, according to the requirements of fire protection regulations, spray heads need to be arranged both above and below the ceiling, wherein the pendent spray head must be equipped with a water baffle. The water baffle needs to be a square or circular metal plate, and its plane area should not be less than 0.12 m², so as to ensure that water can effectively cover the protection area when the spray head works, and avoid affecting the fire extinguishing effect due to improper water flow diffusion.

[0003] At present, in practical engineering applications, the installation method of the water baffle of the spray head is relatively simple and crude. Usually, a metal plate is separately arranged directly below the spray head as the water baffle, and fixed on the ceiling keel or other structural bodies through a simple support. It lacks structural integration with the grid ceiling, and is often exposed on the ceiling surface, which damages the simple and elegant overall aesthetic of the grid ceiling. In addition, the fitting degree between the water baffle and the ceiling is low, which is prone to deformation due to installation stress or water spray impact. At the same time, there is the problem that water splashes pollute the ceiling. And due to the crude installation method, there is often an obvious height difference between the water baffle and the bottom surface of the grid ceiling, generally about 5-10 mm, and it is difficult to ensure the levelness of the water baffle. As a result, when observed from below, an obvious visual gap is formed between the water baffle and the grid ceiling, which seriously affects the decorative effect of the ceiling, thus making it difficult to meet the dual requirements of fire protection function and architectural aesthetics.

[0016] Hereinafter, the implementation of the present application will be described in detail with reference to the accompanying drawings and embodiments, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] As Figures 1-4As shown, the integrated device of a decorative disk and a sprinkler head in a grid ceiling provided by this embodiment comprises a plurality of metal members 1, and the cross section of each metal member 1 is in an inverted "Ω" shape. A plurality of uniformly distributed suspension assemblies 2 are respectively arranged at both ends of the plurality of metal members 1, and the plurality of metal members 1 are connected to each other by a plurality of grid ceiling plates 3. The plurality of metal members 1 and the plurality of grid ceiling plates 3 are spliced and enclosed to form a closed rectangular area 4, and the plane area of the closed rectangular area 4 is not less than 0.12 m². Grid bars 5 are arranged below the grid ceiling plates 3, and a plurality of symmetrically distributed sprinkler head water baffles 6 are installed on the plurality of grid bars 5. The sprinkler head water baffle 6 and the plurality of grid bars 5 connected thereto are an integrally formed structure; A through hole 61 is opened on the sprinkler head water baffle 6, the aperture of the through hole 61 is DN20, and an upwardly protruding annular reinforcing edge 62 is provided at the edge of the through hole 61. The height of the annular reinforcing edge 62 is 5-10 mm, and the wall thickness is 1.5-3 mm. The annular reinforcing edge 62 and the sprinkler head water baffle 6 are of an integrally formed structure. The metal members 1 are fixed via the suspension assemblies 2 uniformly distributed at both ends with the inverted "Ω" shaped cross section, and are spliced with the grid ceiling plates 3 to enclose the closed rectangular area 4 with a plane area of not less than 0.12 m², so as to meet the water retaining specifications. The grid bars 5 below the grid ceiling plates 3 and the sprinkler head water baffles 6 are integrally formed to enhance the structural stability. Wherein, the DN20 through hole 61 on the sprinkler head water baffle 6 is for a sprinkler pipe to pass through, and the annular reinforcing edge 62 with a height of 5-10 mm and a thickness of 1.5-3 mm at the edge of the through hole and the sprinkler head water baffle 6 are integrally formed, which strengthens the strength at the through hole 61 and prevents deformation caused by force during the installation of the sprinkler head or impact of water spray. At the same time, the sprinkler head water baffle 6 can block splashing water from polluting the ceiling, and realizes the integration of decoration and fire-fighting functionality. The bottom of the metal member 1 is flush with the grid ceiling plate 3 to realize hidden installation, which not only meets the requirements of fire-fighting specifications for the installation of the sprinkler head water baffle, but also improves the fitting degree when the sprinkler head water baffle 6 is installed in a grid ceiling decoration space, thereby ensuring the overall aesthetics and achieving the unification of function and aesthetics.

[0018] Further, as Figures 1-4As shown, the metal component 1 includes a crossbar 11, a connecting rod 12, and a suspension component 13. The bottoms of several crossbars 11 are aligned with the bottoms of several grid ceiling panels 3. One end of the connecting rod 12 is fixedly connected to the crossbar 11, and the other end of the connecting rod 12 is fixedly connected to the suspension component 13. The suspension component 13 has a suspension groove 131, which is strip-shaped. The inner end face of the suspension groove 131 is attached to the upper end face of the support rod 7 and fixed with bolts. The bottom of the crossbar 11 is aligned with the bottom of the grid ceiling panel 3, ensuring that the bottom of the metal component 1 is flush with the bottom of the grid ceiling panel 3, thus enhancing the concealment effect. The connecting rod 12 connects the crossbar 11 and the suspension component 13 to form a stable support structure. The strip-shaped suspension groove 131 on the suspension component 13 is attached to the upper end face of the support rod 7 and fixed with bolts. The strip-shaped suspension groove 131 can be adapted to the spacing of the support rod 7, making it easy to adjust the installation position and achieve stable suspension of the metal component 1. This not only ensures the structural load-bearing capacity but also improves the installation adaptability and convenience.

[0019] Furthermore, such as Figures 1-4 As shown, the suspension assembly 2 includes a hanger 21, one end of which is fixedly connected to the top of the wall, and the other end of which is fixedly connected to an adjustable screw 22. A hanging member 23 is located below the adjustable screw 22. The end of the adjustable screw 22 away from the hanger 21 passes through the hanging member 23 and extends to the inside of the hanging member 23. A locking nut 24 is threadedly connected to the end of the adjustable screw 22 located inside the hanging member 23. The bottom surface of the locking nut 24 abuts against the inner top surface of the hanging member 23, and the bottom surface of the locking nut 24 has anti-slip textures. Several hanging members 23 are provided with two symmetrically distributed support rods 7, and the several hanging members 23 are respectively hung on the two support rods. The device is mounted on the support rod 7 and secured with bolts. One end of the rod 21 is fixed to the top of the wall, and the other end is connected to an adjustable screw 22. The adjustable screw 22 passes through the hanger 23 and is threaded to a locking nut 24 with anti-slip texture. Tightening the locking nut 24 can lock the height of the hanger 23, allowing for fine adjustment of the device's vertical position. The hanger 23 is attached to the support rod 7 and secured with bolts. It cooperates with the suspension groove 131 of the metal component 1 to form a double fixation. The adjustable structure adapts to the ceiling installation height error, and the anti-slip texture enhances the locking stability of the locking nut 24. At the same time, the double fixation ensures the overall load-bearing strength, thereby improving the accuracy, stability and adaptability of the device installation.

[0020] Furthermore, such as Figures 1-4 As shown, a slot 31 is provided at the lower end of the grid ceiling panel 3, and a locking block 51 is inserted into the slot 31. The locking block 51 is fixedly installed at the upper end of the grid strip 5. The slot 31 at the lower end of the grid ceiling panel 3 is inserted into the locking block 51 at the upper end of the grid strip 5, so as to quickly realize the positioning and connection of the two, enhance the overall structure, avoid loosening and displacement, simplify the installation process, and ensure that the grid strip 5 and the grid ceiling panel 3 fit tightly, thereby maintaining the decorative aesthetics.

[0021] like Figures 1-4 As shown in this embodiment, the principle of the integrated device for decorative panels and sprinkler heads in the grid ceiling is as follows: In use, first fix the hanging rod 21 to the wall and ceiling. Then, use the adjustable screw 22 to pass through the hanging part 23 and connect it to the locking nut 24 with anti-slip texture. Rotate the locking nut 24 to adjust the height of the hanging part 23 to suit the installation requirements. Then, hang the hanging part 23 on the support rod 7 and fix it with bolts. Then, the suspension part 13 of the metal component 1 is attached to the support rod 7 through the strip suspension groove 131. Its horizontal bar 11 is aligned with the bottom of the grid ceiling panel 3. The connecting rod 12 connects the two to form a support. The metal component 1 and the grid ceiling panel 3 are spliced ​​together to form a closed rectangular area 4 of not less than 0.12㎡. The slot 31 at the lower end of the grid ceiling panel 3 is connected to the grid. The upper end of the grid strip 5 is inserted into the locking block 51 to achieve a stable connection between the two. The grid strip 5 and the integrally formed sprinkler head baffle 6 are kept flat. Finally, the sprinkler pipe is passed through the DN20 through hole 61 on the baffle. The annular reinforcing edge 62 enhances the strength of the through hole 61 to prevent deformation. At the same time, the sprinkler head baffle 6 can also prevent water from splashing and polluting the ceiling, achieving a fusion of decoration and fire protection function. The bottom of the metal component 1 is flush with the grid ceiling panel 3 to achieve a concealed installation, which not only meets the fire protection code requirements for sprinkler head baffle installation, but also improves the fit of the sprinkler head baffle 6 in the grid ceiling decoration, thus ensuring the overall aesthetics and achieving a unity of function and aesthetics.
