In this embodiment, the ceiling plate 11, the head structure and the tail structure are integrally formed by punching, and meanwhile, a first weight-reducing cavity 111 is provided on the ceiling plate 11, and a reinforcing rib 112 is provided in the first weight-reducing cavity 111. Therefore, compared with the traditional ceiling board, the weight is greatly reduced, and the working hours and the transportation cost can be reduced in secondary transportation or transportation; the rigidity of the replaced aluminum plate material is hard, and the integral stamping forming process is adopted to further improve the rigidity of the plate, so that deformation and bending of the suspended ceiling plate under the action of gravity can be prevented after the suspended ceiling plate is installed; the appearance color of the surface of the aluminum plate is more various, the modeling structure is more changeable, and the beautiful decoration requirements of consumers are met.
The slotted plate unit 2 comprises a plate body 201 arranged on the end part of the ceiling plate 11, and a transverse clamping groove 202 arranged on the lower surface of the plate body 201 and used for being spliced with the clamping plate unit 4.
In this embodiment, the connection effect of the two suspended ceilings 11 can be basically satisfied by the vertical clamping groove 1 and the clamping plate unit 4, and the connection strength of the two suspended ceilings 11 is further enhanced by the horizontal clamping groove 202 and the clamping plate unit 4, so that the connection is tighter and the joint is invisible.
The screw unit 3 includes a boss screw mounting plate 301 provided on the plate body 201, a screw 302 provided on the boss screw mounting plate 301 for fixing the ceiling plate 11, and an L-shaped supporting and limiting plate 303 provided on an end of the boss screw mounting plate 301.
In this embodiment, the protruding screw mounting plate 301 is provided with a screw hole 301a for positioning and mounting the screw 302, so as to basically achieve the effect of fixing the ceiling plate 11. The protruding screw mounting plate 301 has an inverted L-shaped structure, and a cavity formed between the protruding screw mounting plate and the upper surface of the subsequent ceiling plate 11 is used for accommodating the tail of the screw 302; the L-shaped supporting and limiting plate 303 extends from the protruding screw mounting plate 301, and the L-shaped supporting and limiting plate 303 abuts against the upper surface of the subsequent ceiling plate 11 after the subsequent ceiling plate 11 is inserted, so as to support the protruding screw mounting plate 301 and prevent the protruding screw mounting plate 301 from deforming.

In this embodiment, the L-shaped mounting groove 501 is formed on the edge of the ceiling board 11, and the length of the L-shaped mounting groove 501 needs to meet the requirement that the L-shaped supporting and limiting plate 303 does not fall into the L-shaped mounting groove 501 after the ceiling board 11 is plugged. Meanwhile, the width of the L-shaped mounting groove 501 needs to be slightly larger than the thickness of the tail of the screw 302 so that the tail of the screw 302 can enter the L-shaped mounting groove 501, and the thickness of the fixing elastic strip 502 is enough to generate downward pressure on the tail of the screw 302, so that the screw 302 can be fixed, and the screw 302 is prevented from backing back to loosen the connection between the ceiling plate 11 and the ceiling.
In this embodiment, as shown in fig. 6, another function of the fixed elastic strip 502 is: after the first ceiling plate 11 is fixed by the screw 302 in a limiting manner, during the process of inserting the second ceiling plate 11 into the first ceiling plate 11, the fixing elastic strip 502 moves along the a direction so as to generate a thrust force along the b direction on the stud of the screw 302, and the thrust force is consistent with the screwing direction of the screw 302, so that the fixing elastic strip 502 can screw the screw 302 during plugging, and the screw 302 is prevented from backing. In this embodiment, the fixed elastic strips 502 provide resistance to insertion of the second ceiling tile 11 into the first ceiling tile 11, but the resistance is moderate and does not affect installation.
In the prior art, after the fixing of the screw 302 is completed, the tail of the screw 302 must not exceed the cavity formed between the protruding screw mounting plate 301 and the upper surface of the subsequent ceiling plate 11, otherwise, the screw 302 will jack up the ceiling plate 11 to cause the surface flatness of the plate body to be poor; in this embodiment, the length of the screw 302 is selected to be larger due to the presence of the L-shaped mounting groove 501, and the length of the screw is only required to be not more than the bottom surface of the L-shaped mounting groove 501.
The rubber strip unit 5 further includes a connection strip 503 provided on the fixed elastic strip 502, and a rubber strip 504 provided on the L-shaped mounting groove 501 and connected to the connection strip 503. The rubber strip 504 is disconnected from the connecting strip 503 in use and is fixedly locked to the vertical clamping plate 402 or the horizontal clamping plate 403 by being installed in the vertical clamping groove 1 or the horizontal clamping groove 202.
In this embodiment, the plugging of the vertical clamping groove 1 with the vertical clamping plate 402 is used for reinforcing the connection between the two suspended ceiling plates 11 in the vertical direction; the plugging of the transverse clamping groove 202 and the transverse clamping plate 403 is used for reinforcing the connection along the connection direction of the suspended ceiling plates 11 to prevent the joint of the two suspended ceiling plates 11 from being oversized; the rubber strip unit 5 has the effect of reinforcing the connection in the third direction to prevent misalignment of the two ceiling tiles 11 after connection. When the two suspended ceilings 11 are connected, the rubber strip 504 is forced to break with the connecting strip 503, and then is placed into the vertical clamping groove 1 or the horizontal clamping groove 202, and the surface friction coefficient of the rubber strip 504 is large, so that the vertical clamping plate 402 or the horizontal clamping plate 403 is difficult to displace after being inserted, and the connection strength between the two suspended ceilings 11 is enhanced. Similarly, the rubber strips 504 provide resistance to insertion of the second ceiling tile 11 into the first ceiling tile 11, but the resistance is moderate and does not affect installation.
