Description

Technical Field

[0001] This utility model relates to the field of interior and exterior wall decoration, and in particular to a non-marking load-bearing device for decorative strips. Background Technology

[0002] In decoration and renovation projects, various wall grids, slabs, and other surface decorative materials are used, especially in high-end shopping malls and stores, where these materials are generally used as decorative backdrops. Merchandise comes in a wide variety of styles and display methods; some items are placed on shelves, while others need to be hung. To save space or for aesthetic reasons, some shelves are typically hung on the wall, requiring load-bearing devices to be installed. However, when there are decorative materials on the wall, the installation of load-bearing devices is often difficult due to structural and load-bearing limitations.

[0003] In existing technologies, load-bearing devices are usually fixed to the surface of decorative materials, using methods such as adhesive, suction cups, and drilling. Adhesive and suction cup installations have weak load-bearing capacity and can only suspend relatively light objects. Drilling installations have stronger load-bearing capacity, but they will damage the surface of the grid decoration. In home and commercial decoration, damaging the decorative wall surface will result in unsightly conditions or holes after removal. Moreover, the load-bearing capacity of the grid decoration is limited. When the weight of the suspended object exceeds the load-bearing range of the decorative board, it will cause the decorative board to break or fall off, affecting the decoration effect. Alternatively, the decorative board can be cut and the load-bearing device can be installed directly on the wall. Although this increases the load-bearing capacity, it will also affect the decoration effect.

[0004] Existing load-bearing devices for decorative panels have weak load-bearing capacity and are prone to damaging the surface of decorative panels, making it difficult to meet load-bearing requirements and decoration design requirements. Utility Model Content

[0005] To address the problem that load-bearing devices on the surface of decorative panels have weak load-bearing capacity and easily damage the surface of the decorative panels, this utility model provides a non-marking load-bearing device for decorative strips.

[0006] This utility model provides a seamless load-bearing device for decorative strip surfaces, employing the following technical solution:

[0007] A non-marking load-bearing device for decorative strips includes a U-shaped bayonet and an insertable profiled steel sheet. The U-shaped bayonet is fixed to the base layer and has a slot along the vertical direction. One end of the insertable profiled steel sheet is vertically inserted into the slot of the U-shaped bayonet, and the other end is bent outward to form a horizontal extension surface and a vertical fixing surface for hanging items.

[0008] By adopting the above technical solution, during the decoration process, the U-shaped clips are fixed to the load-bearing wall of the base layer using expansion bolts, adhesive, or pre-embedded installation foundations. The insertable profiled steel sheet is inserted into the slot formed between the U-shaped clip and the wall, and the items to be hung are suspended on the vertical fixing surface of the insertable profiled steel sheet. This shifts the load-bearing position of the suspended items from the decorative panels to the wall, improving the load-bearing capacity of the device while reducing damage to the appearance of the decorative panels.

[0009] Optionally, the U-shaped bayonet has multiple through holes on both sides for installing expansion bolts to fix it to the surface of the load-bearing wall.

[0010] By adopting the above technical solution, when an item is suspended on the load-bearing device, both sides of the U-shaped bayonet bear the torque, dispersing the load of a single expansion bolt and maximizing the load-bearing capacity.

[0011] Optionally, it also includes wooden blocks and decorative panels. The wooden blocks are fixed to the load-bearing wall of the base layer with structural adhesive or expansion bolts. The decorative panels are installed on the wooden blocks. The space formed by the load-bearing wall of the base layer and the decorative panels is used for wiring and maintenance.

[0012] By adopting the above technical solution, two wooden blocks can be installed on a decorative panel to form a wiring space and ensure the safety of the light strip circuit.

[0013] Optionally, the wooden block and the decorative panel also include a magnetic attraction device disposed on the wooden block. The magnetic attraction device includes two magnets, which are respectively embedded in both ends of the wooden block and the decorative panel for installing the decorative panel.

[0014] By adopting the above technical solution, the decorative panel is easy to disassemble, which facilitates the disassembly and installation of the insert-type profiled steel sheet. It also facilitates the installation or disassembly of the maintenance circuit or the replacement of the light strip.

[0015] Optionally, the inner sides of both the horizontal extension surface and the vertical fixing surface of the insert-type profiled steel sheet are provided with buffer material to reduce wear on the surface of the decorative panel.

[0016] By adopting the above technical solution, when an item is suspended on a load-bearing device, the inserted profiled steel sheet deforms under the action of gravity, which can play a buffering role and protect the surface of the decorative panel.

[0017] Optionally, the slot formed by the U-shaped bayonet and the wall can be configured as a trapezoidal structure that is wider at the top and narrower at the bottom, so that the insertable profiled steel sheet can be pressed tightly on both sides of the slot when it is vertically inserted into the slot.

[0018] By adopting the above technical solution, the lateral displacement of the insertable profiled steel sheet can be limited during the installation process or when the suspended object sways, thus reducing the amplitude of the device's sway.

[0019] Optionally, a detachable extension plate is installed at the slot formed by the U-shaped bayonet and the wall. The vertical end of the extension plate is inserted into the slot, and the horizontal end is provided with a transverse strip protrusion. The horizontal extension surface of the insertable profiled steel sheet is provided with a transverse strip protrusion that matches the horizontal end of the extension plate, which, together with the buffer layer of the profiled steel sheet, forms a front and rear limit.

[0020] By adopting the above technical solution, after the insertable profiled steel sheet is vertically inserted into the slot, the strip-shaped protrusions on the horizontal extension surface match the strip-shaped protrusions at the horizontal end of the extension plate, and together with the buffer layer on the insertable profiled steel sheet, it restricts its front and rear displacement. At the same time, it provides a certain support when the horizontal extension surface of the insertable profiled steel sheet deforms, thereby improving the load-bearing capacity.

[0021] In summary, this utility model has at least one of the following beneficial technical effects:

[0022] 1. By shifting the load-bearing position of the suspended items from the decorative panels to the wall, when the items are suspended on the load-bearing device, both sides of the U-shaped clamp bear the torque, distributing the load of a single expansion bolt. This improves the load-bearing capacity of the device while reducing damage to the appearance of the decorative panels.

[0023] 2. The cushioning material inside the inserted profiled steel sheet reduces wear on the surface of the decorative panel, protecting its decorative effect.

[0024] 3. The extension plate restricts the displacement of the inserted profiled steel sheet, improving the stability of the device itself and thus enabling more reliable hanging of items.

[0025] 4. It can create ample space for wiring, ensuring the safety of the light strip circuit. The design of the decorative panel is easy to disassemble, which facilitates the removal and installation of the load-bearing device, reduces damage to the decorative panel, and allows it to be removed intact. It also facilitates the inspection of the circuit or the replacement of the light strip. Attached Figure Description

Detailed Implementation

[0036] The following combination Figures 1 to 9 The present invention will be described in further detail below.

[0037] This utility model discloses a non-marking load-bearing device for decorative strip surfaces.

[0038] Reference Figure 1 and Figure 2The decorative strip surface-seamless load-bearing device mainly includes: a U-shaped bayonet 100, an insertable profiled steel sheet 200, wooden blocks 300, decorative panels 400, and a magnetic suction device 500 installed on the wooden blocks 300. The U-shaped bayonet 100 is fixed to the surface of the load-bearing wall through through holes on both sides and expansion bolts. After installation, the protruding part of the U-shaped bayonet 100 forms a slot 110 with the surface of the load-bearing wall. The insertable profiled steel sheet 200 is vertically inserted into the slot 110. The two wooden blocks 300 are installed on the load-bearing walls on both sides of the U-shaped bayonet 100 using adhesive or bolts. On the surface, the installation height of the two wooden blocks 300 is consistent with that of the U-shaped bayonet 100, and the distance between the two wooden blocks 300 is equal to the installation distance of the magnetic suction devices 500 at both ends of the decorative panel 400; there is a horizontal support strip 700 connecting the two wooden blocks 300 to support the decorative panel 400; after the wooden blocks 300 are fixed, the decorative panel 400 is attracted to the wooden blocks 300 by the magnetic suction device 500, and the decorative panel 400 is located between the insertion end of the insert-type profiled steel sheet 200 and the vertical fixing surface of the insert-type profiled steel sheet 200.

[0039] Reference Figure 3 , Figure 4 and Figure 5 The U-shaped bayonet 100 has a convex shape on the side, and the depth of the protruding part in the middle matches the thickness of the insertable profiled steel sheet 200, which is used to install the insertable profiled steel sheet 200.

[0040] The insertable profiled steel sheet 200 has a C-shaped structure and forms two vertical surfaces and one horizontal surface. One vertical surface is a vertical insertion surface and is inserted into the slot 110. The other vertical surface is a vertical fixing surface, which can be connected to any other connector in any way or modified into other shapes for hanging items. In this embodiment, it is bolted to any other connector in the form of an opening so as to hang items.

[0041] The magnetic attraction device 500 includes four magnets, which are respectively embedded in the middle of two wooden blocks 300 and at both ends of the decorative panel 400 and fixed by adhesive. The magnets on the wooden blocks 300 are flush with the surface of the wooden blocks 300 near the decorative panel 400, and the magnets on the decorative panel 400 are flush with the surface of the decorative panel 400 near the wooden blocks 300. This device is used to install the decorative panel 400 and is easy to disassemble.

[0042] The implementation principle of Embodiment 1 of this utility model is as follows: During wall decoration, when there is a need to hang items on the surface of the decorative panel 400, the U-shaped bayonet 100 is fixed to the surface of the load-bearing wall through the through holes on both sides with expansion bolts. The vertical insertion surface of the insertable profiled steel sheet 200 is vertically inserted into the slot 110 formed by the U-shaped bayonet 100 and the surface of the load-bearing wall. A wooden block 300 is installed on each of the left and right sides of the U-shaped bayonet 100 on the surface of the load-bearing wall and is fixedly connected to the surface of the load-bearing wall. In this embodiment, structural adhesive is used for installation. The distance between the two wooden blocks 300 is equal to the distance between the magnetic suction devices 500 at both ends of the decorative panel 400 to facilitate the installation of the decorative panel 400. The decorative panel 400 is detachably connected to the two wooden blocks 300 and is attached to the two wooden blocks 300 by magnetic suction devices 500. At this time, the vertical fixing surface of the insertable profiled steel sheet 200 is connected and fixed to the outside of the decorative panel 400 through the horizontal extension surface of the insertable profiled steel sheet 200. Its structure can be changed arbitrarily to install other connectors and hang items. In this embodiment, the drilling method is used.

[0043] Example 2: Refer to Figure 6 , Figure 7 , Figure 8 and Figure 9The difference between this embodiment and Embodiment 1 is that a detachable extension plate 600 is installed at the slot 110 formed by the U-shaped bayonet 100 and the wall. The extension plate 600 includes a connecting plate 610, a reinforcing plate 620, and a supporting plate 630. Two connecting plates 610 are provided, both of which are C-shaped and located on the side of the slot 110 near the expansion screw. One vertical surface of the connecting plate 610 is inserted into the slot 110, and the other vertical surface is attached to the outside of the U-shaped bayonet 100. The reinforcing plate 620 is located on the side of the U-shaped bayonet 100 away from the wall, and both ends of the reinforcing plate 620 are connected to the two connecting plates 610. The supporting plate 630 is connected to the connecting plate... 610 and reinforcing plate 620 are connected, and support plate 630 extends toward decorative plate 400 to abut against decorative plate 400, supporting decorative plate 400 and forming a horizontal support surface; a first transverse strip protrusion is formed on the side wall away from support plate 630 on the horizontal support surface, and a second transverse strip protrusion is provided on the horizontal extension surface of insert-type profiled steel plate 200 to cooperate with the horizontal end of extension plate 600, forming front and rear limiting with the buffer layer of profiled steel plate. The first transverse strip protrusion and the second transverse strip protrusion can be fixed by welding to rigid metal plate, or can be fixed by adhesive rubber material. In this embodiment, adhesive rubber material is preferred. The U-shaped bayonet 100 forms a slot 110 with the surface of the load-bearing wall. The protruding part of the slot is set to a trapezoidal structure with a wider top and a narrower bottom, which matches the width of the insertable profiled steel sheet 200. The vertical insertion surface, horizontal extension surface and vertical fixing surface of the insertable profiled steel sheet 200 are all provided with buffer material 210. The buffer material 210 on the vertical fixing surface is in contact with the decorative panel 400. In this embodiment, the buffer material 210 is selected as a rubber sheet to reduce wear on the surface of the decorative panel 400. The installation position of the buffer material 210 or whether to install it can be selected according to the needs. The buffer material 210 can also be placed on the side in contact with the wall to reduce damage to the wall and reduce the shaking of the insertable profiled steel sheet 200 in the slot 110 due to damage.

[0044] Furthermore, in order to reduce the movement of the insertable profiled steel sheet 200, an elastic protrusion is provided on the side of the vertical surface of the insertable profiled steel sheet 200 located in the slot 110 that is close to the wall. The elastic protrusion abuts against the wall to limit the damage to the wall caused by the end lifting and reduce dust in the decorative layer.

[0045] The implementation principle of Embodiment 2 of this utility model is as follows: When the insertable profiled steel plate 200 is vertically inserted into the trapezoidal slot 110, the trapezoidal slot 110 is wider at the top and narrower at the bottom. Under the action of gravity, the vertical insertion surface of the insertable profiled steel plate 200 moves downward. The U-shaped slots 100 on both sides of the trapezoidal slot 110 gradually press the vertical insertion surface of the insertable profiled steel plate 200, thereby reducing its left and right swaying amplitude. When the vertical insertion surface of the insertable profiled steel plate 200 is fully inserted into the trapezoidal slot 110, its horizontal extension surface is in contact with the horizontal support surface of the extension plate 600. At the same time, the strip-shaped protrusion of the horizontal extension surface matches the strip-shaped protrusion of the horizontal support surface of the extension plate 600, and together with the buffer layer on the insertable profiled steel plate 200, it restricts its front and back displacement and reduces the front and back swaying of the device. When an object is suspended on a load-bearing device, and the inserted profiled steel sheet 200 deforms under the action of gravity, the extension plate 600 provides a certain support for the inserted profiled steel sheet 200, thereby improving its load-bearing capacity. The buffer material 210 on the inner side of the horizontal extension surface and the vertical fixed surface of the inserted profiled steel sheet 200 can reduce the wear on the surface of the decorative panel 400 and play a buffering role to protect the surface of the decorative panel 400.

[0046] In summary, the load-bearing position of the suspended items is transferred from the decorative panel 400 to the wall. When the items are suspended on the load-bearing device, the torque is borne on both sides of the U-shaped latch 100, distributing the load of the individual expansion bolts. This improves the load-bearing capacity of the device while reducing damage to the appearance of the decorative panel 400. The buffer material 210 inside the insertable profiled steel sheet 200 reduces wear on the surface of the decorative panel 400, protects the decorative panel 400, and the decorative extension plate 600 restricts the displacement of the insertable profiled steel sheet 200, improving the stability of the device itself and thus making the suspension of items more reliable. Sufficient wiring space is provided to ensure the safety of the LED strip wiring. The easy-to-disassemble design of the decorative panel 400 facilitates the disassembly and installation of the load-bearing device, and also facilitates the inspection of wiring or replacement of LED strips.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
