Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a floor slab recessed lighting structure. Background Technology

[0002] Many existing hotel lobby lighting fixtures are recessed chandeliers, approximately 4.5 meters in length. These typically consist of multiple recessed chandeliers fixed to the floor slab in a specific arrangement. Each chandelier is usually directly screwed to the floor, making it difficult to determine its orientation, achieve precise installation, and resulting in high positioning difficulty and low efficiency. Furthermore, the numerous screws on the floor affect its structural strength and can damage wiring. Additionally, the unevenness of the floor makes it difficult to determine the relative positions of the chandeliers, requiring confirmation of each chandelier's installation location, leading to low installation efficiency and difficulty in guaranteeing the final installation effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a floor slab recessed chandelier structure that has little impact on the strength of the floor slab structure, high installation efficiency, and easy guarantee of the final installation effect.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A floor slab recessed pendant light structure includes a floor slab, a mounting plate, a ceiling, multiple connectors, and multiple cylindrical pendant lights. The mounting plate is suspended from the floor slab by a suspension rod. The ceiling is suspended from the floor slab and located below the mounting plate. The mounting plate has multiple threaded holes arranged in a horizontal and vertical array. Each connector is fixed to the mounting plate by a fixing screw and is distributed in a predetermined shape. The fixing screw is threadedly connected to the corresponding threaded hole. Each connector passes through the ceiling and connects with each cylindrical pendant light one by one, and is arranged at an angle.

[0005] As a further improvement to the above technical solution: The top of the connector is rotatably fitted with a pressure block, which is fixed to the mounting plate by fixing screws. The top of the connector is pressed between the floor slab and the pressure block.

[0006] The pressure block has a central hole in the middle and is fixed to the mounting plate at the four corners by fixing screws. The top of the connector has a rotating column, which rotates with the central hole. The top of the rotating column has an outer protruding ring, which presses against the floor slab and the pressure block.

[0007] The connector is columnar, and the top of the cylindrical chandelier is fitted and fixed to the corresponding connector.

[0008] The top of the cylindrical chandelier is threaded to the corresponding connector or fixed by bolts.

[0009] The pressure block, rotating column, and connector are connected at the center to form a wire passage. The mounting plate is provided with wire holes between adjacent threaded holes. The wire passage is connected to the corresponding wire hole. The connecting wire of the cylindrical chandelier passes through the corresponding wire passage and wire hole to connect to the main wire.

[0010] The top surface of the cylindrical chandelier rests against the ceiling.

[0011] The ceiling is connected to the corresponding threaded holes by connecting screws.

[0012] The shape of each of the aforementioned connectors can be circular, polygonal, elliptical, or a multi-row straight line.

[0013] The top end of the suspension rod is connected to the floor slab by expansion bolts, and the bottom end is fixedly connected to the mounting plate by fixing bolts.

[0014] Compared with the prior art, the advantages of this utility model are: The construction process of this utility model for a floor-mounted cylindrical chandelier structure is as follows: First, the mounting plate is suspended from the floor slab using hanging rods. Second, each connector is fixed to the mounting plate with fixing screws, arranged in a predetermined shape. Next, the ceiling is suspended from the floor slab, positioned below the mounting plate, with the connectors extending through the ceiling and below it. Finally, each cylindrical chandelier is connected to its respective connector. Since the cylindrical chandeliers are mounted on the mounting plate via connectors, and the mounting plate is suspended from the floor slab using hanging rods, on the one hand, the number of hanging rods is less than the number of cylindrical chandeliers, resulting in fewer connection points with the floor slab and less impact on the structural strength of the floor slab. On the other hand, after the mounting plate is horizontally installed and positioned on the floor slab, each connector only needs to be fixed to the mounting plate with fixing screws, allowing the fixing screws to connect with the corresponding threaded holes. This eliminates the influence of the floor slab's flatness, making it easy to determine the relative positions of the cylindrical chandeliers, resulting in high installation efficiency and ensuring a good final installation effect. Furthermore, the orientation and positioning of each cylindrical chandelier are easy to determine, facilitating precise installation. Attached Figure Description

[0023] Figures 1 to 3This invention illustrates an embodiment of the floor slab recessed pendant light structure. The floor slab recessed pendant light structure of this embodiment includes a floor slab 1, a mounting plate 2, a ceiling 3, multiple connectors 4, and multiple cylindrical pendant lights 5. The mounting plate 2 is suspended on the floor slab 1 by a hanging rod 6. The ceiling 3 is suspended on the floor slab 1 and located below the mounting plate 2. The mounting plate 2 has multiple threaded holes 21 arranged in a horizontal and vertical array. Each connector 4 is fixed to the mounting plate 2 by a fixing screw 7 and is distributed in a predetermined shape. The fixing screw 7 is threadedly connected to the corresponding threaded hole 21. Each connector 4 passes through the ceiling 3 and is connected to each cylindrical pendant light 5 one by one, and is arranged at an angle.

[0024] The construction process of this floor slab recessed chandelier structure is as follows: First, the mounting plate 2 is suspended from the floor slab 1 by the hanging rod 6; second, each connector 4 is fixed to the mounting plate 2 by fixing screws 7 and distributed in a predetermined shape; next, the ceiling 3 is suspended from the floor slab 1, with the ceiling 3 located below the mounting plate 2 and the connectors 4 extending through the ceiling 3 to below the ceiling 3 (the ceiling 3 is a conventional structure, such as consisting of a hanging bracket suspended from the floor slab 1 and multiple square ceiling plates set on the hanging bracket); finally, each cylindrical chandelier 5 is connected to each connector 4 one by one. Since the cylindrical chandeliers 5 are mounted on the mounting plate 2 via connectors 4, and the mounting plate 2 is suspended from the floor slab 1 via rods 6, on the one hand, compared to the number of cylindrical chandeliers 5, the number of rods 6 is less, and there are fewer connection points with the floor slab 1, thus having less impact on the structural strength of the floor slab 1; on the other hand, after the mounting plate 2 is horizontally installed on the floor slab 1 and positioned, each connector 4 only needs to be fixed to the mounting plate 2 by fixing screws 7, so that the fixing screws 7 are threadedly connected to the corresponding threaded holes 21, no longer affected by the flatness of the floor slab 1, the relative positions between each cylindrical chandelier 5 are easy to determine, the installation efficiency is high, and the final installation effect is easy to guarantee. Furthermore, for each cylindrical chandelier 5, the orientation is easy to determine, the positioning is easy, and precise installation is easy to achieve.

[0025] Furthermore, such as Figure 2 As shown, in this embodiment, a pressure block 41 is rotatably fitted onto the top of the connector 4. The pressure block 41 is fixed to the mounting plate 2 by fixing screws 7, and the top of the connector 4 is pressed between the floor slab 1 and the pressure block 41. Thus, before the fixing screws 7 are tightened, the connector 4 can be rotated to adjust its tilt direction, allowing the subsequent cylindrical chandelier 5 to be installed in any tilt direction, thereby improving adjustability and adaptability. Specifically, the pressure block 41 has a central hole 411 in its middle, and its four corners are fixed to the mounting plate 2 by fixing screws 7. The top of the connector 4 has a rotating column 42, which rotatably engages with the central hole 411. The top of the rotating column 42 has an outwardly protruding ring 43, which is pressed between the floor slab 1 and the pressure block 41. Preferably, the pressure block 41 is square.

[0026] Furthermore, in this embodiment, the connector 4 is columnar, and the top of the cylindrical chandelier 5 is sleeved and fixed with the corresponding connector 4, which facilitates the installation of the cylindrical chandelier 5.

[0027] Furthermore, in this embodiment, the top of the cylindrical chandelier 5 is threaded to the corresponding connector 4 or fixed by bolts, which facilitates disassembly and assembly.

[0028] Furthermore, in this embodiment, the pressure block 41, the rotating column 42 and the connector 4 are connected in the center to form a wire passage 8. The mounting plate 2 is provided with wire passage holes 22 between adjacent threaded holes 21. The wire passage 8 is connected to the corresponding wire passage hole 22. The connecting wire of the cylindrical chandelier 5 passes through the corresponding wire passage 8 and wire passage hole 22 to connect with the main wire, preventing the wire from being exposed and improving the installation effect.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the top surface of the cylindrical chandelier 5 rests against the ceiling 3, improving the stability after installation.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the ceiling 3 is connected to the corresponding threaded hole 21 by connecting screws 31. In this way, the ceiling 3 is connected to the mounting plate 2 by connecting screws 31, which improves the stability of the overall structure.

[0031] Furthermore, in this embodiment, the distribution shape of each connector 4 is a multi-row straight line, so that the tilting direction of adjacent rows of cylindrical chandeliers 5 is opposite. In other embodiments, the distribution shape of each connector 4 can also be circular, polygonal, elliptical, etc., depending on actual needs.

[0032] Furthermore, in this embodiment, the top end of the hanger 6 is connected to the floor slab 1 by an expansion bolt 9, and the bottom end is fixedly connected to the mounting plate 2 by a fixing bolt 61. If the fixing bolt 61 occupies the position of the threaded hole 21, the threaded hole 21 at that position can be provided on the fixing bolt 61.

[0033] Furthermore, in this embodiment, the mounting plate 2 is square. In other embodiments, the mounting plate 2 may also be circular, elliptical, etc., depending on actual needs.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
