Description

Technical Field

[0001] The present invention relates to the technical field of suspended ceilings, and in particular to a structure and an installation method of a double-layer keel suspended ceiling that is easy to disassemble. Background Art

[0002] With the advancement of factory production and modular installation in the field of architectural decoration, aluminum honeycomb panels are increasingly used in interior decoration due to their lightweight and high-strength properties. Aluminum honeycomb panels are panels used for ceilings, made of double-sided aluminum skin and aluminum honeycomb core composited at high temperature. They are also called honeycomb sandwich structures and are suitable for civil buildings, vehicle and ship decoration, etc., and are the application of aviation and aerospace materials in the field of civil construction. Currently, the market mostly adopts a single-piece assembly installation method. By setting up top wall keels on the ceiling and using a hanging structure to hang single aluminum honeycomb panels on the lower end of the top wall keels, a whole aluminum honeycomb panel ceiling is formed after splicing. The assembly of single aluminum honeycomb panels is more efficient and convenient, but at the same time, how to ensure that the aluminum honeycomb panels are on the same horizontal plane and have beautiful appearance and stable connections has become a difficult problem faced by the assembly of single aluminum honeycomb panels.

[0003] Patent document CN 114809416 A discloses an aluminum honeycomb ceiling. It utilizes mounting frames built into the ends of the aluminum honeycomb panels and I-shaped members as two connecting components for mounting the panels. Furthermore, by strengthening the connection between these two connecting components (specifically, the I-shaped members clamp the mounting frames and the top panels of the aluminum honeycomb panels together), a stable connection between two adjacent panels is achieved. Consequently, numerous restrictions are placed on the specific construction and connection of these two connecting components, making installation difficult. Furthermore, because the connecting plates of the I-shaped members must be of a certain thickness, a corresponding gap is inevitably formed between adjacent aluminum honeycomb panels. To address the poor visual effect caused by this gap, the patent also includes separate caulking plates secured with screws. This results in a complex installation and inconvenient maintenance, as well as failure to meet the requirements for quick assembly and disassembly required for prefabricated renovations. Summary of the Invention

Specifically, by providing an inlaid edge profile, the aluminum honeycomb panels can be efficiently hung, meeting the requirements of quick installation and disassembly of prefabricated decoration, and the connection between the aluminum honeycomb panels is stable and the overall connection interface is beautiful.

[0005] To achieve the above object, the technical solution of the present invention is:

[0007] The present invention utilizes the abutting effect of the abutting plates of two adjacent inlay profiles, which can effectively save the installation steps of separately filling the gaps between adjacent aluminum honeycomb panels in the prior art, and the connection between the aluminum honeycomb panels is stable, and the overall connection interface is beautiful. In addition, by arranging the inlay profiles partially built into the aluminum honeycomb panels, installation components are saved, and the aluminum honeycomb panels can be efficiently hung, meeting the requirements of quick installation and disassembly of prefabricated decoration.

[0008] Preferably, the mounting assembly further comprises a trapezoidal keel for connecting the hanging member and the edging profile, the upper end of the trapezoidal keel is provided with a sliding plate connected to the hanging member, and the lower end is provided with a control device for connecting the clamping plate.

[0009] The present invention provides a trapezoidal keel, which can solve the technical problem of directly installing the aluminum honeycomb panel to the hanging parts in the prior art, resulting in the ceiling being too high, and can facilitate maintenance and replacement, and is more flexible in application.

[0010] As a further preference, the control device includes a lower connecting plate connected to the clamping plate.

[0011] As a further preference, the other end of the clamping plate where it connects with the abutting plate is provided with an arc-shaped abutting portion, and the abutting control device further includes an arc-shaped limiting plate connected to the arc-shaped abutting portion.

[0012] The present invention can effectively achieve a good connection between the trapezoidal keel and the edge profile through the above technical solution, thereby avoiding the unstable connection between the trapezoidal keel and the edge profile and the occurrence of shaking when installing a single aluminum honeycomb panel.

[0013] As a further preference, the trapezoidal keel further includes symmetrically arranged sliding plates and a control device, and the upper ends of the symmetrically arranged arc-shaped limit plates are connected through an upper control plate.

[0014] The present invention can further reduce the installation error of the adjacent aluminum honeycomb panels by arranging a trapezoidal keel between adjacent aluminum honeycomb panels to achieve bidirectional connection of the aluminum honeycomb panels on both sides, and the connection interface is more level.

[0015] As a further preference, the hanging component is provided with a main board, the upper end of the main board is bent to provide a groove for engaging with the top wall keel, and the lower end surface of the main board is provided with a sliding space for connecting with the sliding plate.

[0016] The present invention provides a hanging piece with a special structure, which makes the installation of the aluminum honeycomb panel simple and easy, without the need for manual bending of the hanging piece. The hanging pieces have good uniformity and can be coordinated with the trapezoidal keel and the edge profile to ensure the appearance flatness between the aluminum honeycomb panels. The aluminum honeycomb panels have good splicing integrity and the surface structure has high stability.

[0017] As a further preference, the sliding plate is a Z-shaped sliding plate.

[0018] As a further preference, a reinforcement plate is provided between the abutting plate and the clamping plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (2) By providing a partially embedded edge profile within the aluminum honeycomb panel, the present invention saves on installation components and can efficiently achieve the hanging of the aluminum honeycomb panel, meeting the requirements of quick installation and disassembly for prefabricated decoration. In addition, compared with the existing technology, the edge profile of the present invention is integrally formed and does not require nailing or gluing to fix it to the aluminum honeycomb panel, making it more environmentally friendly and more flame retardant.

[0027] (3) The present invention provides a trapezoidal keel, which can solve the technical problem of the prior art that the aluminum honeycomb panel is directly installed on the hanging parts, resulting in the ceiling being too high. On the other hand, it can facilitate maintenance and replacement, and the application of components is more flexible.

[0028] (4) The present invention provides a hanging piece with a special structure, which makes the installation of the aluminum honeycomb panel easier. It only needs to be hung so that the groove of the hanging piece is clamped with the top wall keel. There is no need to manually bend the hanging piece in the prior art. Therefore, the hanging pieces after installation have good uniformity and can be coordinated with the trapezoidal keel and the edge profile to ensure the smoothness of the appearance of the aluminum honeycomb panels. The aluminum honeycomb panels have good splicing integrity and high surface structure stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a portion of the embodiments of the present invention, rather than all of the embodiments. Therefore, all other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figures 1 to 7 The structure of the aluminum honeycomb panel 1 in this embodiment is substantially similar to that of conventional aluminum honeycomb panels 1. It includes a top panel 11 and a bottom panel 12 arranged in parallel. The top panel 11 and the bottom panel 12 are connected by a plurality of support panels, which are perpendicular to the top panel 11. There are gaps between adjacent support panels, ensuring the basic strength of the aluminum honeycomb panel 1 while reducing its own weight, facilitating its transportation and installation. To facilitate installation of the aluminum honeycomb panel 1, no support panels are provided between the ends of the top panel 11 and the bottom panel 12. Therefore, mounting grooves are formed at both ends of the aluminum honeycomb panel 1, consisting of the top panel 11, the outermost support panels, and the bottom panel 12, for mounting components.

[0041] In order to minimize the installation inconvenience caused by too many installation components and the problem of poor connection stability between components, the installation component in this embodiment includes a rim profile 2, which includes a three-ring plate 21 connected to the three inner surfaces of the installation groove. In order to realize the two-way connection function of the rim profile 2, the rim profile 2 also includes a folding device 22 connected to one end of the three-ring plate 21, and the folding device 22 includes a clamping plate 222 and an abutting plate 221 for connecting the clamping plate 222 and the three-ring plate 21. In order to avoid the technical problem of poor stability of the aluminum honeycomb panel 1 ceiling caused by only using the clamping plate 222 for connection, the present invention realizes the locking between adjacent aluminum honeycomb panels 1 by a scheme in which the surfaces of the abutting plates 221 of two adjacent rim profiles 2 abut each other. In addition to the above-mentioned locking function, the above-mentioned scheme can also achieve stable connection between two adjacent aluminum honeycomb panels 1, and the connection interface will be neater and more beautiful than the prior art.

[0042] The above-mentioned clamping plate 222 can be connected to the ceiling keel in any way to ensure the technical effect of a stable connection between the two adjacent aluminum honeycomb panels 1 and an overall beautiful connection interface. However, to further optimize the installation assembly, the installation assembly in this embodiment also includes a trapezoidal keel 3 for connecting to the edging profile 2. The lower end of the trapezoidal keel 3 is provided with a control device 32 connected to the edging profile 2. In principle, the control device 32 can only be provided with a lower connecting plate 321 connected to the clamping plate 222. To further limit the clamping plate 222, in this embodiment, the other end of the clamping plate 222 connected to the abutting plate 221 is provided with an arc-shaped abutting portion 2221. The control device 32 also includes an arc-shaped limiting plate 322 connected to the arc-shaped abutting portion 2221. The arrangement of the above-mentioned arc-shaped abutting portion 2221 and the arc-shaped limiting plate 322 can further lock the connection between the control device 32 and the clamping plate 222. In principle, any method of connecting the trapezoidal keel 3 to the ceiling keel can ensure stable connection of the edge profile 2 within the control device 32. However, this embodiment further optimizes the connection method for the upper portion of the trapezoidal keel 3. The trapezoidal keel 3 also includes a sliding plate 31 connected to the control device 32. The sliding plate 31 is Z-shaped and its bottom end is connected to the arc-shaped limit plate 322. Although the above-mentioned trapezoidal keel 3 can realize the hanging function of the aluminum honeycomb panel 1, in order to further reduce the error in the preparation of adjacent trapezoidal keels 3, the trapezoidal keel 3 of this embodiment also includes a symmetrically arranged sliding plate 31 and a control device 32, and the upper ends of the symmetrically arranged arc-shaped limit plates 322 are connected by an upper control plate 33. By connecting adjacent trapezoidal keels 3, on the one hand, the trapezoidal keel 3 can be integrally formed, and the preparation is simpler; on the other hand, through integrated preparation, the horizontal error between the lower connecting plates 321 of the trapezoidal keel 3 is smaller, which is conducive to further achieving the uniformity of the hanging height between two adjacent aluminum honeycomb panels 1.

[0043] The mounting assembly of the present invention also includes a hanger 4 connected to the trapezoidal keel 3. The hanger 4 is provided with a main plate 41. The upper end of the main plate 41 is bent and provided with a groove for engaging with the ceiling keel. After installation, the main plate 41 can be attached to the outer surface of the ceiling keel. The hangers 4 are uniformly hung, which facilitates their coordination with the trapezoidal keel 3 and the edge profile 2 to ensure the smooth appearance of the aluminum honeycomb panel 1. To achieve a good sliding connection between the hanger 4 and the sliding plate 31, the lower end surface of the main plate 41 is provided with a sliding space for connecting with the sliding plate 31.

[0044] In addition, in order to improve the impact resistance of the folding device 22 , a triangular reinforcing plate 223 is further provided between the clamping plate 222 and the abutting plate 221 in this embodiment.
