The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In an embodiment, the convex-type suspended ceiling of the square-letter shape is as shown in fig. 1, fig. 2 and fig. 3, the suspended ceiling is connected with the elevator car through a suspended seat 1, a plurality of reinforcing ribs 2 are installed at the top of the suspended ceiling, in the horizontal direction, the suspended ceiling comprises a central box body 3, an annular inner frame 4 and an annular outer frame 5 which are sequentially connected in a nested manner from inside to outside, the annular outer frame is surrounded by a plurality of outer frame strips, and each outer frame strip comprises an outer frame strip bottom wall 51, an outer frame installation part 52, an outer frame strip outer side curled edge 53 and an outer frame strip inner side curled edge 54.
The outer frame mounting part 52 is formed by the middle part of the bottom wall of the outer frame strip protruding downwards, and the down lamp 6 is fixed on the outer frame mounting part 52. The outer frame strip outer side curled edge 53 is formed by bending the outer side of the outer frame strip bottom wall 51, and the outer frame strip outer side curled edge 53 is fixedly connected with the hanging seat 1. The outer frame strip inner side bead 54 is formed by bending the inner side of the outer frame strip bottom wall 51, the top surface of the outer frame strip inner side bead 54 is lower than the top surface of the outer frame strip outer side bead 53, and the outer frame strip inner side bead is connected with the annular inner frame.
The top of the reinforcing rib 2 is fixed with the outside of the outer frame strip of one of the outer frame strips in a curled mode, and the bottom of the reinforcing rib is fixed with the inside of the outer frame strip of the other outer frame strip in a curled mode.
The ' Chinese character ' Hui ' of the Chinese character ' Hui ' convex type elevator suspended ceiling in the embodiment means that the projection shape of the bottom surface shape of the suspended ceiling on the horizontal plane basically presents a plurality of mutually nested annular shapes. The central box 3 is substantially in the horizontal direction at the lateral center and the longitudinal center of the elevator ceiling, and the "inner side" in this embodiment can be understood as the side near the central box 3, and the "outer side" in this embodiment can be understood as the side facing away from the central box 3. The downward direction in this embodiment is understood to be a direction toward the car floor, and the upward direction in this embodiment is understood to be a direction away from the car floor.
Each outer frame strip in the embodiment is directly connected with the corresponding hanging seat 1 through the outer side turned edge of the outer frame strip, so that the annular outer frame 5 is connected with the elevator car, the annular inner frame 4 is sequentially connected with the annular outer frame 5, and the central box body 3 is connected with the annular inner frame 4. Because the top of central box body 3, annular inside casing 4 and annular outer frame 5 all needn't be connected with the roof of furred ceiling, consequently, the roof can be cancelled to this embodiment, and the convenience is to each down lamp inspection and maintenance.
The heights of the folded edges of two adjacent outer frame strips (including the outer frame strip bottom wall 51, the outer frame mounting part 52, the outer frame strip outer folded edge 53 and the outer frame strip inner folded edge 54) are flush with each other. The two ends of each folding edge in the length direction are provided with inclined edges, and the projection of each inclined edge in the horizontal plane forms an included angle of 45 degrees with the length direction of each folding edge. When each frame strip concatenation encloses into annular frame 5, the hypotenuse at frame strip both ends pastes in the hypotenuse of another frame strip of corresponding end respectively and leans on and forms 45 degrees patchings, in order to further reduce 45 degrees patchings department light leaks, can be sealed at the top of 45 degrees patchings black glue application. Because each outer frame strip is directly connected with the hanging seat 1, the 45-degree seam welding reinforcement is not needed.
In order to prevent the inner side of the ring-shaped outer frame from being deformed by pressing down, the embodiment transfers the pressure of the inner side bead 54 of the outer frame to the outer side bead 53 of the outer frame via the reinforcing rib 2 and then to the hanger base 1, thereby preventing the ring-shaped inner frame 4 from being deformed and collapsing at the joint of the ring-shaped outer frame 5.
