Description

Technical Field

[0001] This application relates to the field of ceiling technology, and in particular to a unitized assembled aluminum panel ceiling structure. In addition, it also relates to a ceiling installation method. Background Technology

[0002] Suspended ceilings are a type of decoration used in the top decoration of residential buildings. They are an important part of interior decoration, serving functions such as heat insulation, sound insulation, and sound absorption. They also act as a concealed layer for electrical, ventilation, air conditioning, communication, fire protection, and alarm piping and equipment.

[0003] In the past, wooden keel and plastic panels were generally used for ceilings. However, the combination of wooden structure and plastic panels has poor fire resistance and is not durable. Therefore, aluminum panel ceiling structures, which have better fire resistance and are easier to install, are now often used.

[0004] While existing aluminum panel ceiling structures are easy to install, disassembly often requires the use of suction cups to pull the aluminum panels down, which are often not readily available in homes. Alternatively, disassembly may require using blades or screwdrivers to pry open the edges of the aluminum panels, which can easily damage them.

[0005] Therefore, a modular aluminum panel ceiling structure is needed. Summary of the Invention

[0006] To address the issues of aluminum panels being difficult to install and disassemble, and easily damaged during disassembly, this application provides a unitized aluminum panel ceiling structure and ceiling installation method.

[0007] The first aspect of this application provides a unitized prefabricated aluminum panel ceiling structure, which adopts the following technical solution: A unitized prefabricated aluminum panel ceiling structure includes a main keel, a secondary keel unit, and an aluminum panel. The main keel is connected to the wall, and the secondary keel unit is connected to the side of the main keel near the ground. The aluminum panel includes a decorative surface and an mounting strip disposed on the edge of the decorative surface. The aluminum panel is connected to the secondary keel unit via the mounting strip. The secondary keel unit includes multiple pairs of clamping members. Each pair of clamping members includes a first clamping plate and a second clamping plate. A receiving cavity suitable for accommodating the mounting strip is formed between the first clamping plate and the second clamping plate. When the clamping member moves away from the ground, the first clamping plate and the second clamping plate can move away from each other, and when the clamping member moves towards the ground, the first clamping plate and the second clamping plate can move closer to each other.

[0008] By adopting the above technical solution, setting the secondary keel unit as a clamping element (clamp) facilitates the installation and removal of aluminum plates. Specifically, when the clamping element moves away from the ground, the first clamping plate and the second clamping plate can move away from each other, thereby allowing the clamp to open. This facilitates inserting the aluminum plate's mounting strip into or removing it from the cavity formed between the first and second clamping plates, thus enabling the installation or removal of the aluminum plate. This makes the installation or removal process more convenient and faster. Furthermore, when the clamping element moves closer to the ground, the first and second clamping plates can move closer to each other to clamp the aluminum plate's mounting strip, thereby achieving the installation and fixation of the aluminum plate.

[0009] Furthermore, each pair of clamping members also includes multiple sets of interleaved connection mechanisms. Each set of interleaved connection mechanisms includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the main keel, and the other end of the first connecting rod is connected to the first clamping plate. One end of the second connecting rod is hinged to the main keel, and the other end of the second connecting rod is connected to the second clamping plate. The hinge point between the first connecting rod and the main keel is located above the second clamping plate, and the hinge point between the second connecting rod and the main keel is located above the first clamping plate.

[0010] By adopting the above technical solution, the first clamping plate and the second clamping plate can move downward under the action of gravity, thereby enabling the first clamping plate and the second clamping plate to move closer to each other to achieve the clamping action.

[0011] Furthermore, pre-compression springs are provided between the first connecting rod and the main keel, and between the second connecting rod and the main keel. When the first clamping plate and the second clamping plate approach and abut against each other, the pre-compression springs can apply a thrust to the first connecting rod and the second connecting rod.

[0012] By adopting the above technical solution, a downward thrust can be applied to the first clamping plate and the second clamping plate through the pre-compression spring, thereby ensuring that the first clamping plate and the second clamping plate have a greater clamping force, making it less likely for the aluminum plate clamped between the first clamping plate and the second clamping plate to fall off.

[0013] Furthermore, a first clamping plate stop strip is provided on the side of the first clamping plate facing the second clamping plate, and the first clamping plate stop strip is located on the side of the first clamping plate away from the main keel and extends along the length direction of the first clamping plate; a second clamping plate stop strip is provided on the side of the second clamping plate facing the first clamping plate, and the second clamping plate stop strip is located on the side of the second clamping plate away from the main keel and extends along the length direction of the second clamping plate; the mounting strip is located on the edge of the decorative surface and perpendicular to the decorative surface, and an edge banding strip is provided on the side of the mounting strip facing the center of the decorative surface away from the decorative surface.

[0014] By adopting the above technical solution, when the first clamping plate and the second clamping plate approach each other to clamp the mounting strip on the aluminum plate, the stop strips of the first clamping plate and the stop strips of the second clamping plate can both abut against the corresponding edge strips, thereby ensuring that the aluminum plate is not easy to fall off.

[0015] Furthermore, the first clamping plate stop bar protrudes from the convex surface of the first clamping plate as an arc surface protruding towards the second clamping plate; the second clamping plate stop bar protrudes from the convex surface of the second clamping plate as an arc surface protruding towards the first clamping plate.

[0016] By adopting the above technical solution, the friction force is reduced when the edge strip comes into contact with the first clamping plate stop strip or the second clamping plate stop strip, so as to facilitate the insertion and installation or disassembly of the aluminum plate.

[0017] Furthermore, the cross-section of the edging strip is semi-circular.

[0018] By adopting the above technical solution, the friction force is reduced when the edge strip comes into contact with the first clamping plate stop strip or the second clamping plate stop strip, so as to facilitate the insertion and installation or disassembly of the aluminum plate.

[0019] Furthermore, the mounting strip is provided with a reinforcing rib on the side facing the center of the finish. The reinforcing rib extends from the edging strip to the finish, and a receiving groove is formed between the reinforcing rib and the edging strip to accommodate the first clamping plate stop strip or the second clamping plate stop strip.

[0020] By adopting the above technical solution, the mounting strip can have sufficient strength to ensure that when the mounting strip moves upward and abuts against the first or second link, the mounting strip is not prone to bending deformation in the vertical direction. This ensures that the mounting strip can abut against the first or second link and push it upward, so that the clamping parts open, thereby facilitating the disassembly of the aluminum plate.

[0021] Furthermore, when the first clamping plate stop strip or the second clamping plate stop strip is in the receiving groove, it can simultaneously abut against the reinforcing rib and the edge banding strip.

[0022] By adopting the above technical solution, it can be ensured that the aluminum plate will not easily wobble in the vertical direction after installation.

[0023] Furthermore, the end of the reinforcing ridge near the receiving groove is configured as an arc surface.

[0024] By adopting the above technical solution, it is easy for the reinforcing rib to pass through the first clamping plate stop bar or the second clamping plate stop bar and continue to move upward.

[0025] The second aspect of this application provides a ceiling installation method, which adopts the following technical solution: A ceiling installation method includes the following steps:

[0026] S1. Connect the main keel to the wall or floor slab, and install the secondary keel unit on the main keel;

[0027] S2. Insert the mounting strip of the aluminum plate into the secondary keel unit;

[0028] S3. Lift the aluminum plate to be replaced and the aluminum plate adjacent to it upwards until the aluminum plate to be replaced comes out of the sub-keel unit, and insert the new aluminum plate into the sub-keel unit.

[0029] By adopting the above technical solution, the installation of aluminum panels is quick and convenient when installing the ceiling, and no other tools are needed when disassembling the aluminum panels. This ensures that the aluminum panels are not easily damaged when inspecting the pipes and lines on the ceiling, and the aluminum panels can be easily disassembled when they need to be replaced.

[0030] In summary, this application includes at least one of the following beneficial effects:

[0031] 1. Setting the secondary keel unit as a clamping element (clamp) facilitates the installation and removal of aluminum plates. Specifically, when the clamping element moves away from the ground, the first clamping plate and the second clamping plate can move away from each other, allowing the clamp to open. This facilitates inserting the aluminum plate's mounting strip into or removing it from the cavity formed between the first and second clamping plates, making the installation or removal process more convenient and faster. Conversely, when the clamping element moves closer to the ground, the first and second clamping plates can move closer together to clamp the aluminum plate's mounting strip, thus securing the aluminum plate.

[0032] 2. Aluminum panels are quick and easy to install when installing ceilings, and no other tools are needed when disassembling them. This ensures that the aluminum panels are not easily damaged when inspecting pipes and lines on the ceiling, and that the aluminum panels can be easily disassembled when they need to be replaced.

[0038] Figure 1 This is a perspective view of a modular aluminum panel ceiling structure according to this application (where one side wall and the floor slab have been removed). Figure 2 yes Figure 1 A magnified view of region A in the middle. See also... Figure 1 and Figure 2 The unitized aluminum panel 3 ceiling structure provided in the first aspect of this application includes a main keel 1, a secondary keel unit 2 and an aluminum panel 3. The main keel 1 is connected to the wall. The secondary keel unit 2 is connected to the side of the main keel 1 near the ground. The aluminum panel 3 includes a decorative surface 31 and an installation strip 32 provided on the edge of the decorative surface 31, so that the aluminum panel 3 can be connected to the secondary keel unit 2 via the installation strip 32.

[0039] Figure 3 This is a front view of a modular aluminum panel ceiling structure according to this application. Figure 4 yes Figure 2 See the enlarged view of region B in the middle. Figure 3 and Figure 4The secondary keel unit 2 is configured to include multiple pairs of clamping members. Each pair of clamping members includes a first clamping plate 21 and a second clamping plate 22. A receiving cavity suitable for accommodating the mounting strip 32 can be formed between the first clamping plate 21 and the second clamping plate 22. When the clamping member moves away from the ground, the first clamping plate 21 and the second clamping plate 22 can move away from each other, and when the clamping member moves towards the ground, the first clamping plate 21 and the second clamping plate 22 can move closer to each other.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, the main keel 1 can be assembled from U-shaped steel, specifically including a frame plate part connected to the side wall and a load-bearing beam and column part connected to the top floor slab. The U-shaped steel can be connected to the side wall or the top floor slab by bolting. The secondary keel unit 2 is specifically connected to the ground side of the U-shaped steel of the load-bearing beam and column part. Setting the secondary keel unit 2 as a clamping member (clamp) can facilitate the installation and removal of the aluminum plate 3. Specifically, when the clamping member moves away from the ground, the first clamping plate 21 and the second clamping plate 22 can engage. The clamps are positioned far apart, allowing the grippers to open so that the mounting strip 32 of the aluminum plate 3 can be inserted into or removed from the cavity formed between the first clamping plate 21 and the second clamping plate 22, thus enabling the installation or removal of the aluminum plate 3. This makes the installation or removal process more convenient and faster. Furthermore, when the clamping components move towards the ground, the first clamping plate 21 and the second clamping plate 22 can move closer together to clamp the mounting strip 32 of the aluminum plate 3, thereby enabling the installation and fixation of the aluminum plate 3.

[0041] like Figure 3 and Figure 4 As shown, each pair of clamping components also includes multiple sets of interlocking connection mechanisms. Each set of interlocking connection mechanisms includes a first connecting rod 23 and a second connecting rod 24. One end of the first connecting rod 23 is hinged to the main keel 1, and the other end of the first connecting rod 23 is connected to the first clamping plate 21. One end of the second connecting rod 24 is hinged to the main keel 1, and the other end of the second connecting rod 24 is connected to the second clamping plate 22. The hinge point of the first connecting rod 23 and the main keel 1 is located above the second clamping plate 22, and the hinge point of the second connecting rod 24 and the main keel 1 is located above the first clamping plate 21. This allows the first clamping plate 21 and the second clamping plate 22 to move downward under the action of gravity, thereby enabling the first clamping plate 21 and the second clamping plate 22 to move closer to each other to achieve the clamping action.

[0042] Furthermore, such as Figure 4As shown, pre-compression springs 25 are provided between the first connecting rod 23 and the main keel 1 and between the second connecting rod 24 and the main keel 1. When the first clamping plate 21 and the second clamping plate 22 approach and abut against each other, the pre-compression springs 25 can apply a pushing force to the first connecting rod 23 and the second connecting rod 24. This allows the pre-compression springs 25 to apply a downward pushing force to the first clamping plate 21 and the second clamping plate 22, ensuring that the first clamping plate 21 and the second clamping plate 22 have a greater clamping force, making it less likely for the aluminum plate 3 clamped between the first clamping plate 21 and the second clamping plate 22 to fall off.

[0043] like Figure 4 As shown, a first clamping plate stop strip 211 may be provided on the side of the first clamping plate 21 facing the second clamping plate 22, and the first clamping plate stop strip 211 is located on the side of the first clamping plate 21 away from the main keel 1 and extends along the length direction of the first clamping plate 21; a second clamping plate stop strip 221 may be provided on the side of the second clamping plate 22 facing the first clamping plate 21, and the second clamping plate stop strip 221 is located on the side of the second clamping plate 22 away from the main keel 1 and extends along the length direction of the second clamping plate 21. 2 extends along its length; the mounting strip 32 is located at the edge of the decorative surface 31 and is perpendicular to the decorative surface 31, and the side of the mounting strip 32 facing the center of the decorative surface 31 away from the decorative surface 31 is provided with an edge banding strip 321, so that when the first clamping plate 21 and the second clamping plate 22 approach each other to form a clamping of the mounting strip 32 on the aluminum plate 3, the first clamping plate stop strip 211 and the second clamping plate stop strip 221 can both abut against the corresponding edge banding strip 321, thereby ensuring that the aluminum plate 3 is not easy to fall off.

[0044] See Figure 4 Furthermore, the first clamping plate stop strip 211 protrudes from the convex surface of the first clamping plate 21 and is an arc surface protruding towards the second clamping plate 22; the second clamping plate stop strip 221 protrudes from the convex surface of the second clamping plate 22 and is an arc surface protruding towards the first clamping plate 21, and the cross section of the edge banding strip 321 is semi-circular. This design can reduce the friction when the edge banding strip 321 abuts against the first clamping plate stop strip 211 or the second clamping plate stop strip 221, so as to facilitate the insertion and installation or disassembly of the aluminum plate 3.

[0045] See Figure 1 and Figure 4The mounting strip 32 has a reinforcing rib 322 on the side facing the center of the trim 31. The reinforcing rib 322 extends from the edging strip 321 toward the trim 31. A receiving groove 323 is formed between the reinforcing rib 322 and the edging strip 321 to accommodate the first clamping plate stop strip 211 or the second clamping plate stop strip 221. The design of the reinforcing rib 322 enables the mounting strip 32 to have sufficient strength, ensuring that the mounting strip 32 is not prone to bending in the vertical direction when it moves upward and abuts against the first connecting rod 23 or the second connecting rod 24. The deformation ensures that the mounting strip 32 can abut against the first link 23 or the second link 24 and push it upwards, so that the clamping member opens, which facilitates the disassembly of the aluminum plate 3. When the first clamping plate stop strip 211 or the second clamping plate stop strip 221 is in the receiving groove 323, it can simultaneously abut against the reinforcing rib 322 and the edge strip 321, so that the aluminum plate 3 is not prone to vertical displacement after being clamped by the first clamping plate 21 and the second clamping plate 22. The end of the reinforcing rib 322 near the receiving groove 323 is set as an arc surface.

[0046] Further, see Figure 4 The end of the reinforcing rib 322 near the receiving groove 323 is set as an arc surface so that the reinforcing rib 322 can pass through the first clamping plate stop strip 211 or the second clamping plate stop strip 221 and continue to move upward. The reinforcing rib 322 can be made by stamping, so as not to increase the weight of the aluminum plate 3.

[0047] It should be noted that when the mounting strip 32 abuts against the first link 23 or the second link 24, it is necessary to ensure that there is a certain gap between the first clamping plate 21 and the second clamping plate 22 and the corresponding aluminum plate 3 surface 31, so that when the mounting strip 32 pushes the first link 23 or the second link 24 upward, the first clamping plate 21 and the second clamping plate 22 do not abut against the corresponding aluminum plate 3 surface 31, thereby allowing the first clamping plate 21 and the second clamping plate 22 to have enough space to rotate, so as to open the jaws (clamping parts).

[0048] Based on the above-described unit-assembled aluminum panel 3 ceiling structure, the ceiling installation method provided in the second aspect of this application includes the following steps:

[0049] S1. Connect the main keel 1 to the wall or floor slab by bolting, and install the secondary keel unit 2 on the main keel 1.

[0050] S2. Insert the mounting strip 32 of the aluminum plate 3 into the secondary keel unit 2 to achieve quick installation of the aluminum plate 3;

[0051] S3. Lift the aluminum plate 3 to be replaced and the aluminum plate 3 adjacent to it upwards until the aluminum plate 3 to be replaced comes out of the secondary keel unit 2 to complete the disassembly of the aluminum plate 3, and insert the new aluminum plate 3 into the secondary keel unit 2.

[0052] Based on the above-mentioned unit-assembled aluminum panel 3 ceiling structure, and using the above-mentioned ceiling installation method, the installation of aluminum panel 3 is faster and more convenient when installing the ceiling. Furthermore, no other tools are needed when disassembling aluminum panel 3, which ensures that aluminum panel 3 is not easily damaged when inspecting pipes and lines on the ceiling. It also makes it easy to disassemble aluminum panel 3 when it is necessary to replace it with a new one.

[0053] The working principle of the unit-assembled aluminum panel 3-type ceiling structure of this application is as follows:

[0054] Setting the secondary keel unit 2 as a clamping element (claw) facilitates the installation and removal of the aluminum plate 3. Specifically, when the clamping element moves away from the ground, the first clamping plate 21 and the second clamping plate 22 can move away from each other, allowing the claw to open. This facilitates the insertion of the mounting strip 32 of the aluminum plate 3 into the receiving cavity formed between the first clamping plate 21 and the second clamping plate 22, or the removal of the mounting strip 32 of the aluminum plate 3 from the receiving cavity, thereby enabling the installation or removal of the aluminum plate 3. This makes the installation or removal process more convenient and faster. Furthermore, when the clamping element moves closer to the ground, the first clamping plate 21 and the second clamping plate 22 can move closer to each other to clamp the mounting strip 32 of the aluminum plate 3, thereby enabling the installation and fixation of the aluminum plate 3.

[0055] The installation of aluminum plate 3 is quick and convenient when installing the ceiling, and no other tools are needed when disassembling aluminum plate 3. This ensures that aluminum plate 3 is not easily damaged when inspecting pipes and lines on the ceiling, and it is also easy to disassemble aluminum plate 3 when it needs to be replaced.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
