Description

Technical Field

[0001] This utility model belongs to the field of interior decoration engineering, and in particular to a modular multi-directional connection wall keel system. Background Technology

[0002] In existing dry-hanging keel wall cladding systems, the keel structure mostly uses metal profiles with a single cross-section (such as C-channels, square tubes, etc.), which are fixed to the surface of the building structure with bolts. Panel installation relies on pre-drilled fixing holes in the keel, using screws for direct fastening or adhesive bonding. This type of structure has the following technical drawbacks in practical applications:

[0003] 1. Poor adaptability of keel structure: Traditional keel has a single cross-section, which cannot meet the installation requirements of multi-directional panels at the same time. When it is necessary to connect decorative panels to different sides of the keel, additional connectors or changes to the keel layout direction are required, resulting in complex structure and material waste.

[0004] 2. Poor panel removability: Existing wall panel connection methods, such as direct screwing or gluing, make maintenance and replacement difficult. Especially in large-area wall panel projects, damage to a local panel requires complete disassembly, resulting in low construction efficiency and high costs.

[0005] Third, the connection method is limited: the panel can only be connected to the keel in one direction (such as the front or the side), and it is not possible to flexibly choose the internal or external hanging or plug-in method according to the design requirements, which limits the styling diversity of the wall panel system. Utility Model Content

[0006] The purpose of this utility model is to provide a modular multi-directional connection wall keel system to solve the technical problems of poor adaptability of the keel structure, poor detachability of the wall panel, and single connection method with the keel in the existing dry-hanging keel wall keel system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A modular multi-directional connection wall joist system includes the original structure, wall L-angle brackets, column joists, and panels. The wall L-angle brackets anchor the original structure to the column joists.

[0009] The cross-section of the column keel has an arch-shaped opening structure, including an integrally formed central convex groove and symmetrically arranged side grooves on both sides.

[0010] The convex groove has keel fixing holes spaced along its length, which connect the column keel to the wall L-angle bracket.

[0011] The side groove is provided with keel external connection holes arranged in rows along the length direction to connect the panel external parts to the column keel. The panel is detachably connected to the keel external connection holes through the panel external parts. The panel external parts include external brackets and / or flat plug components.

[0012] The wall retainer L-shaped corner bracket has an adjustment elongated hole on both limbs. The wall retainer L-shaped corner bracket includes a parallel limb and a vertical limb.

[0013] The central convex groove includes a central groove convex plate and an inner side plate. The keel fixing hole is opened on the central groove convex plate. The side groove shares the same inner side plate as the central convex groove, including the inner side plate, the side groove bottom plate, and the outer side plate. The three side plates of the side groove are all opened with keel external connection holes. The keel external connection holes include the external hanging holes on the side groove bottom plate and the outer side plate, as well as the internal locking holes on the inner side plate. The cavity of the central convex groove forms a locking installation cavity.

[0014] The panel external component is an external bracket that is attached to the external mounting hole. The external bracket includes a corner bracket parallel leg that is anchored to the panel, and also includes an external bracket with a hook that is attached to the external mounting hole. The back of the panel is attached to the external mounting hole of the column keel through the external bracket.

[0015] The external panel component is a flat-insertion assembly that is installed in the mounting cavity and engages with the inner locking hole. The flat-insertion assembly includes a female component and a female component.

[0016] The female component is embedded in the snap-fit ​​mounting cavity and has a one-piece symmetrical butterfly structure. It includes a flat plate that fits tightly against the inner wall of the central groove protrusion plate, corner plates that are connected to both ends of the flat plate and snap into the inner snap holes on both sides, and limiting hooks connected to the corner plates. A child component insertion channel is left between the two limiting hooks.

[0017] The sub-component includes a parallel limb anchored to the panel, and a sub-component insert plate that is vertically inserted into the sub-component insertion channel. The head of the sub-component insert plate is provided with a locking protrusion. The connection between the locking protrusion and the recess of the sub-component insert plate is limited by the end protrusion of the limiting hook. The back of the panel is inserted into the inner locking hole of the column keel through a flat insertion assembly.

[0018] When the opening of the side groove is parallel to the original structure, a wall retaining L-shaped bracket is installed. The parallel leg of the bracket is parallel to the original structure and is anchored to it by structural bolts. The vertical leg of the bracket is anchored to the central groove protrusion plate by wall retaining keel bolts.

[0019] When the opening of the side groove faces the original structure, two centrally symmetrical L-shaped retaining wall brackets are installed. The vertical limbs of the two brackets are connected to form a Z-shape, which is divided into large brackets and small brackets. The parallel limbs of the large brackets are attached and anchored to the original structure by structural bolts. The vertical limbs of the large brackets are inserted into the side groove, and the parallel limbs of the small brackets are attached and anchored to the central groove protrusion plate by retaining wall keel bolts.

[0020] The external mounting brackets and the flat-plug components together form a hybrid wall protection system. The external mounting brackets are used to connect the panel on one side to the column keel, while the flat-plug components are used to connect the panel on the other side to the column keel.

[0021] Compared with the prior art, this utility model has the following features and beneficial effects:

[0022] This utility model adopts an arch-shaped open column keel structure. Traditional keels cannot simultaneously accommodate multi-directional panel installation and structural strength. The column keel uses a one-piece molded arch-shaped cross-section, with a central groove providing a fixing interface with corner brackets, and external mounting holes and internal locking holes on three sides of the side grooves, forming multi-directional connection channels. Through the partitioned design of the central groove and side grooves, the force flow between the keel, the structure, and the panels is separated, improving the overall bending resistance. The three-sided openings of the side grooves support external mounting, internal insertion, and mixed installation of panels, meeting the needs of complex decorative surface designs.

[0023] This utility model adopts an L-shaped corner code and an adjustable elongated hole design, combined with a Z-shaped double corner code configuration, to achieve three-dimensional micro-adjustment of the keel position, adapt to uneven building structure surfaces, ensure keel layout accuracy, and flexibly adapt to the keel opening direction through single corner codes or Z-shaped double corner codes, reducing construction complexity.

[0024] This utility model presents a hybrid connection system combining external attachments and flat-plug components, solving the problem of limited panel connection methods. The external attachments are quickly hooked onto the external holes in the side grooves, while the flat-plug components achieve locking and insertion through a female limiting hook and a male locking protrusion. This system supports bidirectional detachable installation of the panel, facilitating localized maintenance and replacement. The butterfly-shaped female and male insertion channels of the flat-plug components provide self-guiding and anti-detachment locking during insertion, improving connection reliability.

[0025] This utility model's wall protection system significantly improves installation efficiency, structural stability, and decorative flexibility through innovative keel structure and modular connection design. It is especially suitable for large public building projects that require high wall flatness, frequent maintenance, or varied shapes. It is multi-directionally adjustable, bi-directionally detachable, and integrally reinforced, solving the technical bottlenecks of traditional wall protection systems, such as single function and cumbersome construction.
