[0036] Reference Figures 1 to 5 As shown in the drawings, the present application provides a high and large space aluminum plate overall ceiling structure, comprising: a keel 1, a hanging plate 2, a vertical plate 3, and a horizontal plate 4.

[0037] The keel 1 is hung on the ceiling. Specifically, the keel is hung on the ceiling by a hanging rod. The number of keels is multiple. The multiple keels are arranged in the same direction.

[0038] The hanging plate 2 is installed on the keel 1. In this embodiment, the hanging plate is arranged at the position of the keel close to the hanging rod. The bottom of the hanging plate 2 is formed with a supporting beam 21. The two ends of the supporting beam respectively extend to the outside of the opposite sides of the hanging plate. The length of the supporting beam is greater than the length of the hanging plate. The two ends of the supporting beam 21 are respectively hinged with a first pressing rod 22.

[0039] The vertical plate 3 is arranged along the width direction of the keel. The inner side of the vertical plate 3 is formed with a sliding groove. The opposite sides of the groove opening of the sliding groove are oppositely extended to form a anti-off plate 31. The supporting beam 21 is slidably arranged in the sliding groove. The supporting beam 21 is installed with a driving structure 5. The driving structure 5 is used to drive the first pressing rod 22 to support the first pressing rod 22 on the groove wall of the sliding groove.

[0040] The horizontal plate 4 is arranged along the length direction of the keel. The opposite ends of the horizontal plate 4 are respectively hung on the anti-off plates 31 of the adjacent two vertical plates 3. The end of the horizontal plate 4 is downwardly formed with a buckle plate 41. The buckle plate 41 abuts against the opposite sides of the two anti-off plates 31. The opposite ends of the supporting beam 21 are respectively elastically installed with a second pressing rod 23. The second pressing rod 23 is supported on the buckle plate 41 to lock the horizontal plate 4.

[0041] In this embodiment, refer to Figure 2 and Figure 3As shown, the two ends of the support beam 21 are formed with protrusions 211. The opposite sides of the anti-off plate 31 are downwardly formed with limiting flanges 32. The limiting flanges 32 abut against the opposite sides of the two protrusions 211. The buckle plate 41 abuts against the outer sides of the limiting flanges 32.

[0042] As a preferred embodiment, each end of the support beam 21 is provided with two first pressing rods 22. The end of the support beam 21 is provided with an assembly hole. The assembly hole is arranged along the width direction of the support beam. The assembly hole penetrates the support beam. One end of the two first pressing rods 22 is rotatably mounted in the opposite two ports of the assembly hole through a first hinge shaft 221. The first hinge shaft is vertically arranged.

[0043] In combination Figure 3 and Figure 5 As shown, the end of the first pressing rod is connected with a pressing plate 222 through a pressurized air bag. The pressing plate 222 is supported on the groove wall of the sliding groove. The bottom of the first pressing rod is mounted with an expansion air bag 223. The expansion air bag 223 is supported on the groove bottom of the sliding groove. The pressurized air bag is communicated with the expansion air bag through a pipeline.

[0044] The end of the first pressing rod is formed with the pipeline. The pipeline is mounted with a check valve. After the pressing plate at the end of the first pressing rod is pressed against the groove wall of the sliding groove of the vertical plate, the gas in the pressurized air bag is squeezed to be input into the expansion air bag, so that the expansion air bag is vertically expanded to be elongated, and further presses downward the groove bottom of the sliding groove of the vertical plate.

[0045] In some embodiments, the expansion air bag is a vertically arranged bellows. The two ends of the bellows are closed. The pressing plate is arc-shaped. The interior of the end of the first pressing rod is formed with the pipeline to be communicated with the pressurized air bag and the expansion air bag.

[0046] In the present embodiment, the driving structure 5 comprises: a driven gear 51, a transmission rod 52, a driving member 53.

[0047] The driven gear 51 is coaxially connected to the first hinge shaft 221. The transmission rod 52 is movably arranged between the two driven gears 51. One end of the transmission rod 52 is elastically mounted in the assembly hole. The opposite two sides of the transmission rod 52 are respectively formed with toothed patterns. The toothed patterns are engaged with the driven gears 51.

[0048] The upper portion of the support beam 21 is provided with a through hole communicated with the assembly hole. The through hole is arranged below the anti-off plate 31. The driving member 53 is elastically mounted in the through hole. One end of the driving member 53 is supported on the anti-off plate 31. The other end of the driving member 53 abuts against the other end of the transmission rod 52.

[0049] As a preferred embodiment, the end surface of the other end of the transmission rod 52 is obliquely arranged upward toward one end of the transmission rod 52.

[0050] When the support beam is not assembled with the vertical plate, one end of the driving member extends into the sliding groove. After the support beam is slid in the sliding groove of the vertical plate, the anti-disengagement plate presses the driving member and retreats into the through hole. At this time, the driving member pushes against the transmission rod, so that the transmission rod moves along the length direction of the support beam, so that the other ends of the two first pressing rods are close to each other, and then are pressed against the groove walls of the sliding groove of the vertical plate.

[0051] Referring to Figure 3 In the embodiment, a vertical accommodating groove is formed in the hole wall of the through hole. The accommodating groove is arranged along the axial direction of the through hole. The outer portion of the driving member is formed with a guide rod, and the guide rod is slidably arranged in the accommodating groove. The guide rod is connected to one end of the accommodating groove through a jacking spring, and the jacking spring provides a jacking force for the upward movement of the guide rod.

[0052] In the embodiment, the number of the second pressing rods 23 at each end of the support beam 21 is two. The upper portion of the support beam 21 is provided with a first guide groove. The first guide groove is arranged along the length direction of the support beam 21. A base is slidably arranged in the first guide groove. A first elastic member is arranged between the base and one end of the first guide groove. Two second pressing rods are rotatably arranged on the base through a second hinge shaft 231. A tie spring is arranged between the two second pressing rods.

[0053] As a preferred embodiment, the second hinge shaft is vertically arranged. The two second pressing rods are hingedly connected together through the second hinge shaft.

[0054] The side portion of the hanging plate 2 is provided with a vertically arranged second guide groove. A sliding seat 24 is slidably arranged in the second guide groove. One side of the sliding seat 24 extends to the outside of the second guide groove. A second elastic member is arranged between the sliding seat 24 and one end of the second guide groove. The sliding seat 24 supports the second hinge shaft 231.

[0055] Referring to Figure 3 As shown, the bottom portion of the sliding seat 24 is formed with an inclined guide slope surface 240. Before the horizontal plate is mounted on the vertical plate, the sliding seat is lifted upward, the base moves toward the hanging plate under the elastic pulling force of the first elastic member, and the two second pressing rods are spread apart. Then, the end portion of the horizontal plate is arranged on the anti-disengagement plate of the vertical plate, so that the buckle plate of the horizontal plate abuts against the outside of the limiting flange. Finally, the two second pressing rods and the sliding seat are loosened, so that the sliding seat presses downward on the second hinge shaft, the two second pressing rods are contracted and pressed against the outside of the buckle plate of the horizontal plate, and the horizontal plate is locked on the vertical plate.

[0056] The present application provides a construction method of a high and large space aluminum plate overall suspended ceiling structure, comprising the following steps:

[0057] S1, the furring 1 is hung on the ceiling.

[0058] S2, install multiple hanging plates 2 on the keel 1.

[0059] S3, slide the support beam 21 of the hanging plate 2 in the sliding groove of the vertical plate 3.

[0060] S4, drive the first pressing rod 22 by the driving structure 5, and support the first pressing rod 22 on the groove wall of the sliding groove to lock the vertical plate 3.

[0061] S5, hang the opposite two ends of the horizontal plate 4 on the anti-off plates 31 of the adjacent two vertical plates 3, so that the buckling plate 41 abuts against the opposite sides of the two anti-off plates 31, and the second pressing rod 23 of the opposite two ends of the support beam 21 is supported on the buckling plate 41 to lock the horizontal plate 4.

[0062] In the embodiment, the support beam of the bottom of the hanging plate is movably clamped in the sliding groove of the vertical plate. The two second pressing rods are symmetrically installed on the top surface of the two sides of the hanging plate. The two first pressing rods are symmetrically installed inside the two ends of the hanging plate.

[0063] The two second pressing rods are elastically connected by an arc-shaped spring. The ends of the two second pressing rods away from each other are made of rubber material.

[0064] The sliding seat is in contact with the L-shaped stopper connected to the second hinge shaft through the guide slope of the bottom of the sliding seat, and as the sliding seat moves downward, the L-shaped stopper drives the two second pressing rods to move.

[0065] The inside of the first pressing rod is provided with a pipeline for communicating the inflation air bag and the pressurized air bag. The inside of the inflation air bag is filled with gas. When the pressurized air bag is squeezed, the gas in the inside of the pressurized air bag is transported to the inside of the inflation air bag through the pipeline, so that the inside of the inflation air bag is additionally supplemented with gas, and the inflation air bag is vertically expanded.

[0066] The end of the pressurized air bag away from the pressing plate is fixedly connected to the outer wall of the first pressing rod, and the end of the pressurized air bag away from the first pressing rod is fixedly connected to the pressing plate. The pressing plate is made of rubber.

[0067] The transmission rod is elastically installed on the hole wall of the assembly hole through the spring telescopic cylinder. In the embodiment, the spring telescopic cylinder includes a sleeve and a guide rod. The guide rod is coaxially connected to the end of the transmission rod. The other end of the guide rod is movably inserted into one end of the sleeve. The other end of the sleeve is connected to the hole wall of the assembly hole. The sleeve is provided with a spring. The spring is supported on the other end of the guide rod and the bottom of the sleeve. When the transmission rod is forced to move, the driven gear will be driven to rotate through the teeth or teeth on both sides of the transmission rod, so that the driven gear drives the first pressing rod to rotate through the rotating shaft, and at this time the spring telescopic cylinder is compressed.

[0068] The end of the transmission rod away from the spring telescopic cylinder is in contact with the driving member. The contact end of the transmission rod and the driving member is provided with an inclined angle (i.e. an inclined end surface).

[0069] When the top end of the driving piece contacts the limiting flange of the vertical plate, the limiting flange will press downward to make the driving piece move downward, and the bottom end of the driving piece will abut against the inclined surface of the transmission rod, so that the end of the transmission rod away from the driving piece extrudes the spring telescopic cylinder.

[0070] The two sides of the vertical plate are clamped with the horizontal plate, the upper end of the hanging plate is clamped with the keel, and the top surface of the keel is equidistantly installed with the hanging rod.

[0071] The side of the horizontal plate close to the hanging plate is in abutment with the second pressing rod.

[0072] When the high and large space aluminum plate overall ceiling structure is constructed, first, the keel is installed at the top of the high and large space through the hanging rod, the hanging plate is clamped on the keel and placed on the adjacent side of the hanging rod, and the vertical plate is clamped on the two sides of the hanging plate.

[0073] When the vertical plate is clamped on the two sides of the hanging plate, the top end of the two sides of the vertical plate presses downward on the driving piece, so that the driving piece moves downward under force, and the driving piece extrudes the inclined angle end of the transmission rod in the process of moving downward, at this time, the transmission rod will move away from the driving piece, in the process of moving, the transmission rod will be engaged with the driven gear synchronously, so that the driven gear drives the first pressing rod to rotate through the rotating shaft, at this time, the transmission rod will drive the two first pressing rods to rotate simultaneously through the driven gear and the rotating shaft, the two first pressing rods will rotate towards each other, so that the pressing plate presses the side wall of the vertical plate, the pressing plate will be extruded to compress the gas bag due to the resistance of the vertical plate and the movement of the first pressing rod, so that the gas in the gas bag is compressed to the inside of the pipeline, and the gas is transported to the inside of the expansion gas bag through the pipeline, at this time, the inside of the expansion gas bag is filled with additional gas, so that the expansion gas bag expands vertically.

[0074] After that, in the process of expansion of the expansion gas bag, the bottom surface will contact the top surface of the vertical plate, and the expansion gas bag will continuously extrude the top surface of the vertical plate due to the filling of the gas in the expansion gas bag, so that the vertical plate is subjected to the downward pressure from the expansion gas bag above, the clamping force is improved, and the ends away from each other of the two first pressing rods will abut against the side wall of the vertical plate, so that the fastening effect of the vertical plate and the hanging plate is improved.

[0075] After the vertical plate and the hanging plate are installed, the horizontal plate is horizontally clamped on the adjacent two vertical plates, the first spring is compressed by pulling the sliding seat upward, the sliding seat is released from the pressure of the L-shaped block, the two second pressing rods are moved towards each other under the elastic force of the arc spring, the L-shaped block moves away from the second pressing rod in the interior of the hanging plate, the horizontal plate is clamped above the vertical plate, the sliding seat is released from the upward pull, the sliding seat is driven downward by the elastic force of the first spring, the inclined angle end of the sliding seat gradually pushes the L-shaped block to move away from the hanging plate, the two second pressing rods gradually expand away from each other, the two second pressing rods are gradually in contact with the side wall of the horizontal plate due to the continuous pushing of the L-shaped block, so as to improve the reinforcement of the vertical plate and the horizontal plate.

[0076] The high and large space aluminum plate overall hanging ceiling structure of the application realizes the pressure locking of the vertical plate and the horizontal plate through the cooperation of the first pressing rod and the second pressing rod, avoids the unstable connection between the vertical plate and the hanging plate, prevents the unstable connection, and improves the installation efficiency and installation quality of the aluminum plate overall hanging ceiling structure.
