[0002] The aluminum plate integral ceiling is mainly made of aluminum alloy materials. Through special design and processing technology, the aluminum alloy plate is fixed to the ceiling through the "keel", forming a unique ceiling structure (such as the Chinese patent announcement number CN116254974B).

[0003] During the installation of the overall suspended ceiling of the aluminum plate in a large space, due to the large space, the number of parts such as keels required on the top will increase, and the number and area of ​​the overall aluminum plate splicing will also increase. The connection between the existing aluminum plates and the keel frames is generally achieved by overlapping, that is, the aluminum plate is directly stuck between the keel frames. However, in the process of installing and splicing the keel frames, the horizontal plates and vertical plates need to be spliced ​​into a similar mouth-shaped style, which will increase the gravity in the connection area between the horizontal plates and the vertical plates. Based on the existing direct overlapping method, the increase in gravity will cause the connection area between the horizontal plates and the vertical plates to be unstable, which will affect the subsequent installation effect of the overall suspended ceiling, so it needs to be improved.

[0034] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

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

[0037] The keel 1 is suspended from the ceiling. Specifically, the keel is suspended from the ceiling through a suspension rod. There are multiple keels. 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 a position of the keel close to the hanging rod. A supporting beam 21 is formed at the bottom of the hanging plate 2. The two ends of the supporting beam extend to the outside of the opposite sides of the hanging plate respectively. 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. A slide groove is formed on the inner side of the vertical plate 3. Anti-slip plates 31 are formed on opposite sides of the notch of the slide groove. The support beam 21 is slidably arranged in the slide groove. A driving structure 5 is installed on the support beam 21. The driving structure 5 is used to drive the first pressing rod 22 so that the first pressing rod 22 is supported on the groove wall of the slide groove.

[0040] The transverse plate 4 is arranged along the length direction of the keel. The opposite ends of the transverse plate 4 are respectively hung on the anti-slip plates 31 of the two adjacent vertical plates 3. The ends of the transverse plate 4 are turned down to form a gusset plate 41. The gusset plate 41 abuts against the opposite sides of the two anti-slip plates 31. The opposite ends of the support beam 21 are elastically mounted with second pressing rods 23. The second pressing rod 23 is supported on the gusset plate 41 to lock the transverse plate 4.

[0041] In this embodiment, see Figure 2 and Figure 3As shown, convex ribs 211 are formed at both ends of the support beam 21. The opposite sides of the anti-slip plate 31 are turned down to form a limiting flange 32. The limiting flange 32 abuts against the opposite sides of the two convex ribs 211. The buckle plate 41 abuts against the outer side of the limiting flange 32.

[0042] As a preferred embodiment, two first pressing rods 22 are provided at each end of the support beam 21. An assembly hole is provided at the end of the support beam 21. The assembly hole is provided 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 installed in two opposite ends of the assembly hole through the first hinge shaft 221. The first hinge shaft is provided vertically.

[0043] Combination Figure 3 and Figure 5 As shown, the end of the first pressing rod is connected to a pressing plate 222 through a pressurized airbag. The pressing plate 222 is supported on the groove wall of the chute. An inflatable airbag 223 is installed at the bottom of the first pressing rod. The inflatable airbag 223 is supported on the groove bottom of the chute. The pressurized airbag is connected to the inflatable airbag through a pipeline.

[0044] The end of the first pressing rod is formed with the pipeline. The pipeline is installed with a check valve. After the pressure plate at the end of the first pressing rod presses against the groove wall of the chute of the vertical plate, the gas in the pressurized airbag is squeezed and input into the expansion airbag, so that the expansion airbag expands vertically and stretches, and then the expansion airbag presses downward against the groove bottom of the chute of the vertical plate.

[0045] In some embodiments, the expansion airbag is a vertically arranged bellows. Both ends of the bellows are closed. The pressure plate is arc-shaped. The end of the first pressing rod is formed with the pipeline to communicate with the pressurized airbag and the expansion airbag.

[0046] In this embodiment, the driving structure 5 includes: a driven gear 51 , a transmission rod 52 , and 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 installed in the assembly hole. The transmission rod 52 is formed with teeth on opposite sides. The teeth mesh with the driven gear 51.

[0048] A through hole connected to the assembly hole is provided on the upper part of the support beam 21. The through hole is arranged below the anti-slip plate 31. The driving member 53 is elastically installed in the through hole. One end of the driving member 53 is supported on the anti-slip plate 31. The other end of the driving member 53 is supported on the other end of the transmission rod 52.

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

[0050] When the support beam is not assembled and connected with the vertical plate, one end of the driving member extends into the slide groove. After the support beam is slid into the slide groove of the vertical plate, the anti-slip plate presses the driving member and retracts it into the through hole. At this time, the driving member pushes against the transmission rod, causing the transmission rod to move along the length direction of the support beam, so that the other ends of the two first pressing rods approach each other, and then press against the groove wall of the slide groove of the vertical plate respectively.

[0051] See also Figure 3 As shown, in this embodiment, a vertically arranged accommodating groove is provided in the hole wall of the through hole. The accommodating groove is arranged along the axial direction of the through hole. A guide rod is formed on the outside of the driving member, 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 supporting spring, which provides a lifting force for the guide rod to rise.

[0052] In this embodiment, the number of the second pressure-resisting rods 23 at each end of the support beam 21 is two. A first guide groove is provided at the upper portion of the support beam 21. The first guide groove is arranged in a square shape along the length of the support beam 21. A base is slidably arranged in the first guide groove. A first elastic member is installed between the base and one end of the first guide groove. The two second pressure-resisting rods are rotatably installed on the base through a second hinge shaft 231. A tie spring is connected between the two second pressure-resisting 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] A second vertical guide groove is provided on the side of the hanging plate 2. A sliding seat 24 is slidably provided 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 installed between the sliding seat 24 and one end of the second guide groove. The sliding seat 24 is supported on the second hinge shaft 231.

[0055] See also Figure 3 As shown, the bottom of the sliding seat 24 is formed with an inclined guide slope 240. Before the horizontal plate is installed on the vertical plate, the slide is lifted upward, and the base moves toward the hanging plate under the elastic tension of the first elastic member, and the two second pressing rods are stretched out at the same time. After that, the end of the horizontal plate is placed on the anti-slip plate of the vertical plate, so that the buckle plate of the horizontal plate is against the outer side of the limit flange. Finally, the two second pressing rods and the sliding seat are loosened, so that the sliding seat presses the second hinge shaft downward, and the two second pressing rods shrink and press against the outer side of the buckle plate of the horizontal plate, thereby locking the horizontal plate on the vertical plate.

[0056] The present invention provides a construction method of a large-space aluminum plate integral ceiling structure, comprising the following steps:

[0057] S1. Hang the keel 1 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 into the slide groove of the vertical plate 3.

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

[0061] S5. Hang the opposite ends of the transverse plate 4 on the anti-slip plates 31 of the two adjacent vertical plates 3 respectively, so that the buckle plate 41 abuts against the opposite sides of the two anti-slip plates 31, and the second pressure rods 23 at the opposite ends of the supporting beam 21 are supported on the buckle plate 41 to lock the transverse plate 4.

[0062] In this embodiment, the support beam at the bottom of the hanging plate is movably connected to the slide groove of the vertical plate. The two second pressing rods are symmetrically installed on the top surface of both 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 via an arc spring. The ends of the two second pressing rods that are away from each other are made of rubber material.

[0064] The sliding seat contacts the L-shaped abutment block connected to the second hinge shaft through the inclined guide slope at the bottom thereof, and as the sliding seat moves downward, the L-shaped abutment block drives the two second pressing rods to move.

[0065] A pipeline for connecting the inflatable airbag and the pressurized airbag is provided inside the first pressing rod, and the inflatable airbag is filled with gas. When the pressurized airbag is squeezed, the gas inside the pressurized airbag is transported to the inflatable airbag through the pipeline, so that the inflatable airbag is additionally supplemented with gas, causing the inflatable airbag to expand vertically.

[0066] One end of the pressurized airbag away from the pressing plate is fixedly connected to the outer wall of the first pressing rod, and one end of the pressurized airbag 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 mounted on the wall of the assembly hole through a spring telescopic tube. In this embodiment, the spring telescopic tube 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 wall of the assembly hole. A spring is arranged in the sleeve. 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 pressure rod to rotate through the rotating shaft, and the spring telescopic tube is compressed at this time.

[0068] One end of the transmission rod away from the spring telescopic cylinder is in contact with the driving member, and the contact ends of the transmission rod and the driving member are provided with an oblique angle (ie an inclined end surface).

[0069] When the top of the driving member contacts the limiting flange of the vertical plate, the limiting flange will apply downward pressure to move the driving member downward, and the bottom of the driving member will contact the inclined surface of the transmission rod, so that the end of the transmission rod away from the driving member squeezes the spring telescopic cylinder.

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

[0071] One side of the transverse plate close to the hanging plate is in contact with the second pressing rod.

[0072] During the construction of the large space aluminum plate integral ceiling structure of the present invention, the keel is first installed on the top of the large space through the suspension rod, the suspension board is clamped on the keel and placed on the adjacent side of the suspension rod, and the vertical panels are clamped on both sides of the suspension board.

[0073] When the vertical plates are stuck on both sides of the hanging plate, the top ends of both sides of the vertical plates press the driving member downward, so that the driving member is forced to move downward. During the downward movement of the driving member, the beveled end of the transmission rod is squeezed. At this time, the transmission rod will move to the end away from the driving member. During the movement of the transmission rod, it will synchronously mesh with the driven gear, so that the driven gear drives the first pressure rod to rotate through the rotating shaft. At this time, the transmission rod will drive the two first pressure rods to rotate simultaneously through the driven gear and the rotating shaft. The two first pressure rods will rotate toward each other, so that the pressure plate presses against the side wall of the vertical plate. The pressure plate is subjected to the resistance of the vertical plate and the movement of the first pressure rod, which will cause the pressure plate to squeeze the pressurized airbag so that the gas inside the pressurized airbag is compressed into the inside of the pipeline, and the gas is transported to the inside of the expansion airbag through the pipeline. At this time, the inside of the expansion airbag is filled with additional gas, causing the expansion airbag to stretch vertically.

[0074] Afterwards, during the expansion process, the bottom surface of the inflatable airbag will contact the top surface of the vertical plate, and due to the filling of gas inside the inflatable airbag, the inflatable airbag will continuously squeeze the top surface of the vertical plate, so that the vertical plate is subjected to the downward pressure from the inflatable airbag above, thereby increasing the clamping force. At the same time, the opposite ends of the two first pressure rods will contact the side wall of the vertical plate, thereby increasing the fastening effect between the vertical plate and the hanging plate.

[0075] After the vertical plates and hanging plates are installed, it is necessary to clamp the transverse plate horizontally on the two adjacent vertical plates, pull up the sliding seat to compress the first spring, and the sliding seat releases the pressure on the L-shaped resistance block. The two second pressure rods will move toward each other due to the elastic force of the arc spring, so that the L-shaped resistance block moves inside the hanging plate in the direction away from the second pressure rod. At this time, clamp the transverse plate above the vertical plate, release the pull-up on the sliding seat, and the sliding seat is driven downward by the elastic force of the first spring, and the angled end of the sliding seat gradually pushes the L-shaped resistance block to move away from the hanging plate. At this time, the opposite ends of the two second pressure rods will gradually expand outward. At this time, due to the continuous push of the L-shaped resistance block, the opposite ends of the two second pressure rods will abut against the side wall of the transverse plate, thereby improving the reinforcement of the vertical and transverse plates.

[0076] The large-space aluminum plate integral ceiling structure of the present invention realizes the pressing and locking of the vertical panels and the horizontal panels by setting the cooperation of the first pressing rod and the second pressing rod and other structures, thereby avoiding the unstable connection between the vertical panels and the hanging panels, preventing the occurrence of unstable connection, and improving the installation efficiency and installation quality of the aluminum plate integral ceiling structure.

[0077] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
