Description

Technical Field

[0001] This utility model relates to a dry-hanging component for installing decorative panels, and also to a surface system formed by using the dry-hanging component to install decorative panels. Furthermore, this utility model relates to a building having the surface system. Background Technology

[0002] There are eight main methods for installing decorative panels, one of which is the dry-hanging method. The dry-hanging method refers to the process of fixing decorative panels with metal hangers. It does not require the application of mortar and has the characteristics of strong shock resistance, but it has relatively high requirements for the metal hangers.

[0003] Known dry-hanging methods generally require pre-grooving in materials such as stone veneer panels. The hangers have hooks that mate with these grooves, allowing for fixation to the wall via a base frame. This base frame is typically a lightweight keel, often made of hot-dip galvanized steel, hence the name "light steel keel." However, it's not limited to steel; aluminum alloy keels are also widely used in the construction industry for veneer panel installation.

[0004] It should be further clarified that the installation of decorative panels on walls using, for example, hangers does not necessarily require the use of a base frame. In some implementations, decorative panels can also be installed using hangers pre-embedded in the base wall.

[0005] Furthermore, in some implementations, the hangers are pre-embedded in the base wall. These hangers consist of two sets: one set supports the decorative panel from below, and the other hooks it from above. Grooves need to be cut on both the top and bottom sides of the decorative panel. Given that most decorative panels are made of hard and brittle materials such as stone, grooving creates stress concentration at the grooved areas, making them prone to breakage, especially on the relatively fragile edges. However, currently, grooving on decorative panels is mainly done on the edges of the panels.

[0006] In view of this, some implementations offset the grooved area towards the inside of the panel. In these implementations, the groove is generally made on the inner surface of the decorative panel, and the distance between the grooved area and the upper or lower edge of the decorative panel is usually 50-100mm, thus avoiding the relatively fragile edge. However, making the groove on the inner surface of the decorative panel requires consideration of the reliability of the panel hook. Therefore, the corresponding groove is often an upward-sloping blind hole-shaped groove. The initial cutting difficulty of the groove is relatively large, and the corresponding hanger needs to be hooked to the decorative panel. In these implementations, the installation of the decorative panel is also relatively difficult because the groove is located on the back of the decorative panel, and the installation is obstructed by the decorative panel itself. The alignment of the groove and the hanger is relatively difficult, the installation efficiency is relatively low, and it is not easy to identify whether the hanger is properly engaged, which may lead to problems with assembly reliability.

[0007] Furthermore, in recent years, a new method of installing decorative panels using back bolts has emerged. This involves pre-installing back bolts on the decorative panel and then using nuts to attach the panel to the base frame on-site. This method faces the same challenges as slotting the back of the decorative panel: it is often difficult to accurately locate the corresponding bolt holes on the base frame during installation. Additionally, due to the obstruction of the decorative panel, the locking of the back bolts and corresponding nuts must be completed within the space between the decorative panel and the wall, making it difficult to deploy installation tools and severely impacting installation efficiency.

[0008] All of the above-mentioned decorative panels require grooving, including back bolts, which also require grooving. This causes localized damage to the decorative panel substrate, affecting the strength of the decorative panel itself. Furthermore, grooving the decorative panels involves a grooving process, resulting in overall low efficiency. Utility Model Content

[0009] In view of this, the purpose of this utility model is to provide a dry-hanging component that does not require grooving of the decorative panel, thereby helping to improve the installation efficiency and reliability of the decorative panel; this utility model also provides a surface system for installing decorative panels using the dry-hanging component, and this utility model further provides a building with the surface system.

[0022] If it is a panel structure, the dry-hanging component serves as a support for the decorative panel; correspondingly, the limiting portion is located at the end of the extended panel structure and has a pair, with the corresponding two limiting portions located at both ends of the end of the panel structure.

[0023] If it is a slat structure, the middle part of the limiting part is connected to the end of the slat structure, and the limiting part is divided into two sub-limiting parts in the middle, one of which is used to mate with the outer surface of a decorative panel, and the other is used to mate with the outer surface of another decorative panel.

[0024] Optionally, the side of the base plate connected to the slat structure has a flange, the width of which is greater than the width of the slat structure, thus forming a clamping space between the flange and the limiting part for clamping the decorative panel.

[0025] Optionally, the slat structure is located on one side or two opposite sides of the base plate;

[0026] If the slat structure is located on one side of the base plate, the other side of the base plate opposite to that side is folded over to form a support plate or baffle.

[0027] If it is a support plate, the dry-hanging component constitutes a support for the decorative panel; if it is a baffle, the dry-hanging component constitutes a side component for limiting the corners of the decorative panel.

[0028] Optionally, the limiting part is a sheet-like limiting piece.

[0029] Optionally, the limiting piece gradually narrows from one end connected to the supporting connection to the other end, and the side of the limiting piece facing the decorative panel matches the outer surface of the decorative panel.

[0031] Accordingly, one side of the supporting connection or two opposite plates serve as bending edges, and the supporting connection is formed by the corresponding bending.

[0032] The limiting piece is formed by bending the end of the connecting part towards the opposite side of the bottom plate where the limiting piece is located, punching it into a limiting piece and bending it towards the opposite side, or punching a notch at the end of the supporting connecting part. The bottom of the notch is used to support the decorative panel and / or to limit the upper edge of the decorative panel.

[0033] Optionally, the limiting part is an arc-shaped structure or a half-arc-shaped structure, and the arc-shaped side of the arc-shaped structure is the side facing away from the decorative panel.

[0034] Optionally, the base plate has a plurality of mounting holes for riveting the dry-hanging component to the base frame or bolting it to the base wall.

[0035] According to a second aspect of the present invention, a finishing system is provided, comprising:

[0036] The base frame or connecting components are fixed to the base wall, wherein the connecting components are arranged in predetermined rows and columns on the base wall;

[0037] The dry-hanging component is the dry-hanging component described in the first aspect of the present utility model embodiment, which is fixed on the base frame or distributed on the base wall through connecting components;

[0038] The decorative panel has its lower edge supported by a first set of dry-hanging components, and the outer surface of the lower edge of the decorative panel is constrained by the limiting portion of the first set of dry-hanging components; the upper edge of the decorative panel is located at the upper limit of a second set of dry-hanging components, and the outer surface of the upper edge of the decorative panel is constrained by the limiting portion of the second set of dry-hanging components.

[0039] According to a third aspect of the present invention, a building is provided having the finishing system described in the second aspect of the present invention.

[0040] In embodiments of this utility model, the provided dry-hanging component has a supporting connecting portion for supporting the decorative panel from below. This supporting connecting portion is fixed to the base plate in a manner substantially perpendicular to the base plate or is an integral structure with the base plate. A limiting portion is provided at the end of the supporting connecting portion, which is used to cooperate with the outer surface of the decorative panel, equivalent to hooking the decorative panel from the outside. The dry-hanging component located above the decorative panel in the decorative system also has a limiting portion for hooking the decorative panel. With the help of this structure, the decorative panel can be reliably bound to the decorative system. The aforementioned base plate is directly or indirectly fixed to the base wall. The decorative panel can slide in from the left or right side of the two pre-installed sets of dry-hanging components. Under these conditions, on the one hand, the dry-hanging component is not obstructed by the decorative panel when installed on, for example, the base frame, ensuring that the installation conditions of the dry-hanging component are less restricted, thereby easily ensuring the reliability of the dry-hanging component installation; on the other hand, after the dry-hanging component is installed in place, the decorative panel can slide in from one side, easily ensuring installation efficiency. Furthermore, the dry-hanging component based on this utility model does not require slots or holes in the decorative panel, thus reducing damage to the decorative panel, and further, it eliminates the need to slot the decorative panel, thereby improving the overall installation efficiency of the decorative panel.

[0062] It should be understood that decorative panel 5 has a decorative surface and a back surface opposite to the decorative surface. In the installed state, the decorative surface is the side facing people. Therefore, the decorative surface of decorative panel 5 is also called the outer surface, and its back surface is also called the inner surface. The inner surface is usually not visible in the installed state of decorative panel 5.

[0063] In a relatively large number of applications, the decorative panel 5 is usually installed vertically, so that when installed, the decorative panel 5 has a defined top, bottom, left and right orientation.

[0064] It should also be noted that, given that decorative panel 5 is not necessarily installed vertically, in some applications, decorative panel 5 can be installed horizontally, such as decorative panel 5 for ceilings, which is constructed with the aid of a roughly horizontally arranged base frame. However, for the sake of consistency, the example based on the aforementioned vertical installation state is used to characterize the installation state of decorative panel 5. The top and bottom of decorative panel 5 here are only used to describe the two opposite sides of decorative panel 5, and do not have any spatial up or down meaning.

[0065] Although the decorative panel 5 has a certain thickness, for example, it is a rectangle with a certain thickness, and therefore has four sides, people are more accustomed to using the edge to refer to the side of the decorative panel 5. This is a common naming convention for boards and will not cause ambiguity.

[0066] Regarding the thickness of the decorative panel 5, its thickness ranges from 3mm to 50mm. According to the dry-hanging component of this utility model embodiment, it is mainly used for the installation of decorative panels 5 with a thickness of less than or equal to 25mm, and mainly uses relatively thin decorative panels 5, such as decorative panels 5 with a thickness of less than or equal to 15mm.

[0067] In some embodiments, the dry-hanging fitting can be customized according to the thickness of the installed decorative panel 5, while in other embodiments, the dry-hanging fitting can have a relatively wide range of applications, such as... Figure 11 The dual-card intermediate piece 4 shown has a certain adaptability to the thickness range of the decorative panel 5 because it has a second spring 44.

[0068] As described in the background section, the decorative panel 5 used in known dry-hanging components generally requires slots or holes to be cut in the decorative panel 5. This increases the processing difficulty of the decorative panel 5 used in such dry-hanging components and also reduces the strength of the decorative panel 5 itself.

[0069] In the embodiments of this utility model, the provided dry-hanging component does not require slotting on the decorative panel 5. The decorative panel 5 is installed by supporting the decorative panel 5 or limiting the upper edge of the decorative panel 5 while hooking the outer surface of the decorative panel 5. This improves installation efficiency and reduces damage to the decorative panel 5.

[0070] See Figures 8-14 Examples of various dry-hanging components are shown, which have a base plate, such as Figure 8The first base plate 26 shown is a flat plate structure, but other shapes are also possible. However, a flat plate structure is preferred for its main body. Other shapes are primarily chosen to improve overall rigidity. Figure 8 In the middle, the first base plate 26 may have reverse folded flanges on the left and right sides. These flanges are roughly parallel to the left and right sides of the keel 3, and will not cause assembly interference. However, the presence of the flanges will greatly increase the rigidity of the first base plate 26.

[0071] exist Figure 8 In the illustrated structure, three rivet holes 27 are provided on the first base plate 26, so that the first base plate 26 can be riveted to the keel 3 by means of the rivet holes 27.

[0072] Riveting is a static connection and a non-detachable connection, which provides a high degree of reliability.

[0073] In some implementations, bolting can also be used to install dry-hanging components, but this is a secondary option and will not be discussed further here.

[0074] Figure 1 The illustrated structure is an example of a dry-hanging component using a base frame as the mounting substrate. However, it should be understood that in some applications, the decorative panel 5 can be installed directly on the base wall without the need for a keel 3, for example, by pre-embedding a given number of anchors on the base wall, using the anchors as the substrate for installing the decorative panel 5. Regarding the pre-embedded components such as anchors used for directly installing the decorative panel 5, other pre-embedded components are also possible, such as pre-embedded plates or blocks, as long as the portion of such pre-embedded components exposed is for connecting, for example, the first base plate 26.

[0075] If a base frame is used as the installation substrate, the base plate of the dry-hanging component mainly uses the longitudinal keels in the base frame as the installation substrate. In some embodiments, the transverse keels can also be used as the installation substrate. Holes can be pre-drilled on the corresponding keels 3, or holes can be drilled on-site according to the dimensions of the building, such as the exterior wall.

[0076] Given the complex site conditions, besides dimensional adaptation, cutting and installing parts of the decorative panel 5 is a common practice in this field. However, it should be understood that, for example, building exterior walls, constructed according to design specifications, generally have minimal dimensional errors. In contrast, the construction of the base frame takes into account the construction errors of the base wall and makes adjustments accordingly. Therefore, the dry-hanging components installed on the base frame are laid out based on the dimensions of the decorative panel 5 installation drawings, and the dry-hanging components are installed on the base frame to ensure good dimensional adaptability with the decorative panel 5.

[0077] It should be noted that the dry-hanging component based on this embodiment of the utility model does not require pre-grooving on the decorative panel 5. In other words, it has better adaptability to the size of the decorative panel 5, and no further adjustments are needed on-site, such as adjusting the lateral position of the dry-hanging component, resulting in higher installation efficiency. In contrast, for known pre-grooved decorative panels 5, the dry-hanging component needs to be aligned with the groove, often requiring frequent adjustments, which further reduces the installation efficiency of the decorative panel 5.

[0078] See Figure 2 In the figure, the first support 2 is not constrained in the horizontal direction. Therefore, when the size of the decorative panel 5 of the same specification changes due to processing error (which is generally small), the first support 2, which is not constrained in the horizontal direction, does not need to be adjusted in the horizontal direction. Therefore, the installation efficiency of the decorative panel 5 can be improved.

[0079] Correspondingly, known dry-hanging components often require the use of, for example, elongated holes to make fine adjustments when dimensional and assembly accuracy is insufficient.

[0080] And as Figure 7 As shown, for example, the first support 2 can be pre-fixed on, for example, the keel 3, unlike traditional dry-hanging parts which need to be installed while the decorative panel 5 is covered. Therefore, based on the embodiment of the present invention, the construction efficiency of the dry-hanging parts is relatively high, and the reliability of its installation is also relatively easy to guarantee.

[0081] In a preferred embodiment of this utility model, the dry-hanging component is made of sheet metal stamping, and the thickness of the sheet metal used is 0.3mm~2mm, which is selected according to different decorative panels 5, specifically the maximum weight of a single decorative panel 5.

[0082] Regarding the choice of materials for dry-hanging components, the main options are galvanized steel sheet (SECC), hot-dip galvanized steel sheet (SGCC), and stainless steel. These sheet metals all have relatively good corrosion resistance and a certain degree of toughness, allowing them to be formed into shapes such as... Figure 8 The first reed 21 shown is an example.

[0083] Regarding the selection of stainless steel, SUS301 and SUS304 are the main choices, with SUS301 being the preferred option due to its relatively better elastic properties.

[0084] Regarding the dry-hanging parts based on the embodiments of this utility model, they are mainly formed by stamping. It should be known that the consistency of workpieces manufactured by stamping and other forming methods with the aid of molds is relatively good, that is, the dimensional consistency is relatively good and the interchangeability is better. Therefore, they are more suitable for the production of dry-hanging parts.

[0085] The base plate of the dry-hanging component is a substrate, used as described above for connecting the dry-hanging component to, for example, the keel 3 or components pre-embedded in the base wall. The preferred connection method is riveting, which offers relatively high reliability. Figure 2 and Figure 3 Riveting, for example, using rivets 6 is employed. In some embodiments, welding can also be used directly. In this case, it is not necessary to pre-drill rivet holes 27 on the base plate. On-site welding can be performed by spot welding, segment welding, or full welding according to the determined installation position. The main consideration is that there is often no need to adjust the dry-hanging parts according to the dimensional error of the decorative panel 5. Therefore, the assembly reliability between the dry-hanging parts and, for example, the keel 3 can be further ensured.

[0086] If, for example, riveting is used, the corresponding example Figure 8 The number of rivet holes 27 is three, and the three rivet holes 27 are arranged in an isosceles triangle to improve the reliability of the fixation.

[0087] Figure 8 and Figure 9 The illustrated dry-hung component is a relatively small dry-hung component that primarily provides support, and it has a relatively small number of rivet holes 27. In contrast, Figure 10 On the illustrated dry-hanging component, the second base plate 45 has six rivet holes 42 arranged in three rows. The two rivet holes 42 in the middle row are relatively far apart, thereby forming relatively good assembly reliability.

[0088] exist Figure 12 and Figure 14 The illustrated structures mainly show dry-hanging components with relatively small dimensions, such as... Figure 12 The dry-hanging fitting shown is equipped with three rivet holes 109, while... Figure 14 The dry-hanging fitting shown also has three rivet holes (128). Figure 12 The three rivet holes 109 shown are Figure 14 The rivet holes 128 shown are also arranged in an isosceles triangle pattern.

[0089] exist Figure 13 In the illustrated structure, there are four rivet holes 111, three of which are distributed on the same straight line, and the remaining one is located on one side of the straight line where the three rivet holes 111 are distributed, forming an isosceles triangle overall.

[0090] Regarding keel 3, light steel keel is mainly used. You can choose building light steel keel DC50×15×1.5 GB11981, or other building light steel keels, including ceiling keels.

[0091] In the embodiments of this utility model, the load-bearing keel of the light steel keel forming the base frame is mainly a channel-shaped light steel keel. The channel-shaped light steel keels can be interconnected or independent of each other. If interconnected, they are mainly interconnected by T-shaped keels, which constitute the horizontal keel, while the aforementioned channel-shaped light steel keel constitutes the vertical keel.

[0092] The horizontal keel can also be a channel-type light steel keel, which can serve as the installation base for the dry-hanging components. Thus, depending on the site conditions and the specifications of the decorative panel 5, multiple dry-hanging components can be distributed on, for example, the bottom edge of the decorative panel 5.

[0093] Based on the principle of this utility model, the installation of the decorative panel 5 is mainly achieved by the support of the dry-hanging part (hereinafter referred to as the lower dry-hanging part) located at the lower edge of the decorative panel 5 and the upper limit and positioning of the dry-hanging part (hereinafter referred to as the upper dry-hanging part) located at the upper edge of the decorative panel 5, as well as the cooperation between the limiting part on the upper and lower dry-hanging parts and the outer surface of the decorative panel 5.

[0094] The naming convention for the upper and lower dry-hanging components mentioned above is based on the decorative panel 5, but... Figure 3 and Figure 4 The intermediate component 4 shown in the figure serves as both the upper and lower dry-hanging component, and is based on the dry-hanging component itself as a reference.

[0095] As can be seen from the foregoing description of the principle of this utility model, the limiting part of the dry-hanging component will be exposed in the installed state, but because its individual size is relatively small, it has little impact on the overall visual effect of the exterior wall, for example.

[0096] It should be noted that decorative panels themselves have relatively high strength, such as stone decorative panels. This is the main reason why hook-type dry-hanging fittings are commonly used for installing stone decorative panels. For the dry-hanging fittings based on this utility model embodiment, the size of the limiting part does not need to be too large, such as... Figure 3 , Figure 4 The middleware 4 in the middleware uses the representation in Figure 11 The second limiting piece 43, with a length of 5-16mm for mating with the outer surface of the decorative panel 5, takes into account the dimensional accuracy of the decorative panel 6. For example, the portion of the second limiting piece 43 located on the side of the connecting support rib 47 (hereinafter referred to as the sub-limiting piece) should be at least 8mm long, and generally should not be too large, as this would result in material waste; it should generally not exceed 12mm. Under these conditions, the dry-hanging part exposed on the outer side of the decorative panel 5 is relatively small, and as mentioned above, the dry-hanging part is preferably a stamped part, and the main body of the limiting piece constituting the limiting part is sheet-like, resulting in a relatively small visual effect. At the same time, its own size is also relatively small relative to the decorative panel 5, having little impact on the overall visual effect.

[0097] Even if it affects the overall visual effect, as mentioned earlier, dry-hanging parts are often arranged in a regular pattern, and the arrangement of the corresponding exposed limiting parts must also be regular. Regular arrangement itself often has a relatively good visual effect.

[0098] The main function of the limiting part is to provide a constraint in the normal direction of the trim panel 5 to prevent the trim panel 5 from falling outward. Ideally, when the trim panel 5 is kept vertical, for example, no horizontal force will be generated. The limiting part is mainly to prevent the trim panel 5 from falling outward or tipping over.

[0099] It should be noted that the decorative panel 5 is affected by installation accuracy and actual factors such as wind load, which will generate an outward force. However, the outward force is relatively small relative to the weight of the decorative panel 5. The limiting part is mainly kept in the working position by the pulling action generated by the connection between the limiting part and the base plate.

[0100] It is obvious that the base plate must be located inside the decorative panel 5, while the limiting part must be located outside the decorative panel 5. Furthermore, the base plate is the substrate of the dry-hanging component, and the limiting part needs to be directly or indirectly connected to the base plate. In this embodiment of the invention, the limiting part is connected to the base plate via a supporting connecting part, which is located on one side of the limiting functional part of the limiting part. This creates a U-shaped structure between the limiting functional part of the limiting part, the supporting connecting part, and the base plate, which fits onto the side of the decorative panel 5. The base plate directly or indirectly positions and limits the inner surface of the decorative panel 5, while the limiting part limits the outer surface of the decorative panel 5.

[0101] from Figure 2 and Figure 7 ,as well as Figure 4 and Figure 6 As can be seen, the part constituting the support connection part in the figure is also used to support the decorative panel 5 from the bottom or to provide positioning and limiting of the decorative panel 5 from the top. Therefore, the support connection part is a reusable structure, that is, it is used for both the connection between the limiting part and the base plate, and for supporting or positioning and limiting the decorative panel 5.

[0102] Figure 8 In the middle, the first upright plate 24 constitutes a supporting connection part, which in Figure 8 The upper end of the part is punched to form two first limiting pieces 25 that constitute the limiting part, and the lower end of the supporting connecting part is connected to the first base plate 26. In a preferred embodiment, the supporting connecting part and the base plate are formed by bending a sheet metal sheet to form an integral connection.

[0103] Figure 8 The illustrated dry-hanging component mainly supports the trim panel 5 from the bottom, generally serving as the bottom support for the trim panel 5 located at the bottom of the trim system, wherein the first vertical plate 24 is used to support the lower edge of the trim panel 5.

[0104] At the same time, from Figure 8 As can be seen, the first upright plate 24 is also used to connect the first limiting piece 25 and the first base plate 26. In use, as... Figure 2 As shown in the diagram, keel 3 is a longitudinal keel, constructed on the exterior wall of the building and installed vertically. The first base plate 26 of the first support 2, installed on keel 3 by rivets 6, is in a vertical state. At this time, the first upright plate 24 is located at the lower edge of the first base plate 26 and extends vertically outward, thus forming a horizontal plate. The first upright plate 24... Figure 2 The first upright plate 24 supports the decorative panel 5 from below, forming a support plate. Simultaneously, the outwardly extending ends of the first upright plate 24 have a pair of first limiting pieces 25. Figure 2 As can be seen, the first limiting piece 25 engages with the outer surface of the trim panel 5, thereby hooking the trim panel 5 from the outside.

[0105] Figure 11 A dual-card middleware 4 is shown. Figure 6 This is a schematic diagram of the fixing structure of the dual-card intermediate component 6 on the keel 3. Figure 1 , Figure 3 and Figure 4 This shows a schematic diagram of the double-card intermediate component 6 dry-hanging the decorative panel 5. As can be seen from these example diagrams, the double-card intermediate component 6 has a second base plate 42, which is a flat plate in these example diagrams. In use, it is fixedly installed on, for example, a keel 3. If the keel 3 is a longitudinal keel, then the second base plate 42 is a vertical plate in the installation state.

[0106] Furthermore, a connecting support rib 47 constituting the supporting connection portion is provided on each of the left and right sides of the second base plate 42. Figure 3 and Figure 4 As can be seen in the illustrated structure, the upper side of the connecting support rib 47 supports the trim panel 5 located above it, while the lower side of the connecting support rib 47 provides upper limit and positioning for the trim panel 5 located below it. Therefore, the double-clamp intermediate piece 4 is a dual-function dry-hanging piece for the trim panel 5. Figure 4 As can be seen, it can be used for positioning or limiting the four decorative panels 5.

[0107] The second limiting piece 43 located at the top of the supporting connecting rib 47 extends downward in the figure to form a lower limiting piece, which is used to mate with the outer surface of the decorative panel 5 located on the lower side, and hooks the corresponding decorative panel 5 from the upper end. Correspondingly, the second limiting piece 43 located at the top of the supporting connecting rib 47 extends upward in the figure to form an upper limiting piece, which is used to mate with the outer surface of the decorative panel 5 located on the upper side, and hooks the corresponding decorative panel 5 from the lower end.

[0108] As can be seen from the above, both the first upright plate 24 and the connecting support rib 47 are roughly vertically connected to the corresponding bottom plate, thus providing a supporting or pressing function, and correspondingly cooperating with the lower or upper edge of the decorative panel 5 to form upper and lower limits or positioning.

[0109] The second limiting piece 43, located at, for example, the end of the connecting support rib 47, extends to both sides of the connecting support rib 47, clearing the connecting support rib 47 in the normal (thickness direction) of the decorative panel 5, thereby... Figure 11 As shown, a roughly U-shaped structural part, i.e., a U-shaped opening structure, is formed on both sides of the connecting support rib 47, and it cooperates with the inner and outer surfaces of the decorative panel 5 to form a locking mechanism for the decorative panel.

[0110] Regarding, for example, the connecting support rib 47, it is connected to, for example, the second base plate 45 in a generally perpendicular manner, while... Figure 8 In the illustrated structure, the first vertical plate 24 and the first bottom plate 26 are approximately perpendicular to each other. The included angle between them may not be equal to 90°, but rather there is an angle relative to the vertical state. Under the condition that the first vertical plate 24 supports the decorative panel 5, a certain amount of elastic deformation will be generated, so that the first vertical plate 24 and the first bottom plate 26 are approximately perpendicular to each other.

[0111] As mentioned earlier, since sheet metal made of materials such as stainless steel has relatively high rigidity, the angle between the first vertical plate 24 and the first bottom plate 26 relative to the vertical state should not exceed 3°.

[0112] Regarding the limiting part, the structure shown in the accompanying drawings mainly adopts a sheet-like structure. This is mainly because in the preferred embodiment of this utility model, the dry-hanging part is mainly made of sheet metal stamping, and the sheet-like structure is easy to construct.

[0113] In some embodiments, for example Figure 8 The first limiting piece 25 shown is located at the upper end of the first upright plate 24 in the figure. The width of the first upright plate 24 is 50mm to 85mm. It is formed into two substrates by punching. After the substrate is bent vertically to one side of the first upright plate 24, the length is, for example, 30mm. The effective length can reach 8mm as mentioned above. Therefore, it can be formed into a rectangular or circular structure by, for example, winding or bending multiple times. The rectangular or circular structure can be overhanging relative to, for example, one side of the first upright plate 24, and can be matched with the outer surface of the decorative panel 5.

[0114] If the processing precision of the decorative panel 5 is relatively high, even considering thermal expansion and contraction, an effective length of 8mm for the first limiting piece 25 is sufficient to meet the usage requirements. Furthermore, under the condition of relatively high processing precision of the decorative panel 5, the effective length of the first limiting piece 25 can be even shorter.

[0115] The effective length here refers to, for example, the length by which the first limiting piece 25 extends vertically toward the first upright plate 24. The same applies to other limiting parts.

[0116] Regarding the limiting portion, it can extend to one side of the supporting connection portion or to both sides of the supporting connection portion relative to it, to adapt to different applications. Vertical extension is preferred. The limiting portion, together with the supporting connection portion, forms a hook structure. Clearly, based on the hooking action on the decorative panel 5, the limiting portion does not necessarily need to extend vertically relative to the supporting connection portion.

[0117] Accordingly, if the limiting portion extends to one side of the supporting connecting portion, the supporting connecting portion is used to support the lower edge of the decorative panel 5, for example... Figures 8-10 The first support member 2 shown has a first limiting piece 25 extending to one side of the first upright plate 24, thereby forming a one-sided U-shaped opening structure with the first base plate 26.

[0118] and Figure 11 , Figure 12 and Figure 14 The illustrated dry-hanging component, such as the second limiting piece 43, extends in opposite directions relative to the connecting support rib 47, thereby forming a U-shaped structure on both sides.

[0119] Furthermore, when the structure has U-shaped openings on both sides, such as the connecting support rib 47, it serves both as support and as an upper limit and positioning element, and therefore can be used as... Figure 3 and Figure 4 The dual-card intermediate component 4 shown is used for the installation of four decorative panels 5.

[0120] Furthermore, for example, the first support 2, in Figure 1 and Figure 2 In the illustrated structure, the trim panel 5 is supported at the corner. Considering that the trim panel 5 located at the bottom may bear a greater load based on the support rib 47 connected to the double-clamp intermediate member 4 located on the upper side, in addition to using the first support member 2 at the corner for support, the trim panel 5 located at the bottom can also be provided with a first support member 2 located in the middle or on both sides of the middle. Under this condition, the first support member 2 located at the two corners can be omitted.

[0121] For ease of description, the space between the limiting part and the base plate is called the clamping space.

[0122] In a preferred embodiment, the base plate has a spring to provide a clamping allowance in the clamping space. In embodiments of this invention, besides... Figure 13 Apart from the dry-hung components illustrated, all other dry-hung component examples have springs. The following examples illustrate this. Figure 9 and Figure 10The example of a dry-hung component is used for illustration; other dry-hung components can be explained by analogy.

[0123] exist Figure 9 and Figure 10 In the illustrated structure, two first spring pieces 21 are directly formed on the first base plate 26 using a stamping process. Figure 10 The image shows that in the initial state, in the normal direction of the first base plate 26, the first spring 21 and the first limiting piece 25 have an initial clamping distance h, which is less than the thickness of the decorative panel 5. Therefore, when the decorative panel 5 is installed using such dry-hanging components, the first spring 21 is compressed by the decorative panel 5 against the first base plate 26, and the resulting rebound force can ensure that the decorative panel 5 is reliably bound and does not move freely.

[0124] If relying solely on hard limits, due to the influence of processing and assembly precision, there will be a certain amount of movement between the decorative panel 5 and the corresponding functional components of the dry-hanging parts. Affected by factors such as wind, the decorative panel 5 will generate a certain amount of movement in the inward and outward directions, which can easily lead to fatigue loads and fatigue cracks, potentially reducing the service life of the decorative panel 5.

[0125] By using reeds, the effects of processing and assembly precision can be overcome, and the decorative panel 5 can be more reliably bound to, for example, the base frame.

[0126] Furthermore, as mentioned earlier, due to the influence of processing accuracy and assembly accuracy, relying solely on hard limits often results in insufficient restraint or difficulty in assembly under the condition of meeting rapid assembly requirements. The presence of springs can provide an appropriate margin, thereby effectively restraining the decorative panel 5 while achieving rapid installation, thus having better application prospects.

[0127] Regarding the amount of movement of the reed in the normal direction of, for example, the first base plate 26, it should preferably not exceed 8mm, and generally should not be less than 3mm.

[0128] Regarding the shape of the reed, such as Figure 9 and Figure 10 The first spring 21 shown is a warped sheet-like body. It can generally be directly punched out using a punch, thereby forming a first cut 23 on, for example, the first base plate 26, and the flipped-up part of the first base plate forms the first spring 21.

[0129] As mentioned above, the dry-hanging component based on the present invention is suitable for the decorative panel 5 to slide in from one side. Therefore, the warped springs, such as the first spring 21, are conducive to manual assistance in pressing down the springs, which facilitates the sliding of the decorative panel 5 from one side.

[0130] In example Figure 9In the illustrated structure, the main body of the first spring 21, which is warped relative to the first base plate 26, is a rectangular piece. The angle between the rectangular piece and the first base plate 26 is 15° to 45°, preferably not greater than 30°.

[0131] The main body end of the first spring 21 is connected to an arched part, which bends in the opposite direction to the side where the first base plate 26 is located, thereby forming an arch. This makes it less likely to scratch the back of the decorative panel 5, or in other words, the friction is relatively small, which is conducive to the installation of the decorative panel 5.

[0132] Springs such as the first spring 21 formed by the stamping process have their main body connected to the first base plate 26 and then extend obliquely upward, with the end forming an arc to form a transition arc and reduce frictional resistance with the back of the decorative panel 5.

[0133] At this time, the elastic spring and the corresponding limiting part form a clamping ability with a certain elastic margin, so that the decorative panel 5 can be reliably bound.

[0134] To establish the aforementioned cooperation between the spring and the limiting part, the number of functional parts of the limiting part used for limiting can correspond one-to-one with the number of springs, or it can be a one-to-many relationship. However, the number of springs should not be excessive; generally, it should be the same as the number of functional parts of the limiting part used for limiting, or twice the number of such functional parts. Under these conditions, each dry-hanging component should be equipped with at least one spring corresponding to each decorative panel 5, but usually no more than two springs.

[0135] from Figure 9 and Figure 10 As can be seen in the illustrated structure, the spring and the limiting part are not necessarily directly aligned, but have a certain alignment deviation. This alignment deviation is mainly used to avoid forming interference.

[0136] Regarding the supporting connection, two main forms are proposed in the embodiments of this utility model: one is a plate structure, such as... Figure 8 and Figure 9 The first upright plate 24 shown, and in more embodiments, such as Figure 11 , Figure 12 and Figure 14 The connecting support rib 47 shown, for example, is an overall slat structure.

[0137] It should be noted that in the mechanical field, a slat structure refers to a plate with a relatively large aspect ratio, such as a rectangular plate with an aspect ratio greater than or equal to 2.

[0138] If it is a panel structure, the dry-hanging component serves as a support for the decorative panel 5; correspondingly, as Figure 9As shown, the first limiting piece 25 constituting the limiting portion is located at the end of the extended plate structure portion, and there is a pair of them, with the corresponding two first limiting pieces 25 located at both ends of the end of the plate structure portion. Furthermore, Figure 9 In the middle, the ends of the first upright plate 24 that extend vertically outward relative to the first base plate 26 are rounded, and the rounded corners extend further towards the first limiting piece 25, so that the first limiting piece 25 also exhibits a semi-arched structure. The smooth connection reduces the sharp parts and makes the first limiting piece 25 more aesthetically pleasing.

[0139] Figure 14 The example dry-hanging component is equivalent to Figure 11 The illustrated half-structure of the dry-hanging component is used for the installation of the trim panel 5 located on the side. Figure 14 In the figure, the fifth base plate 122 has a flange on the side where it connects with the fifth support connecting rib 126. This flange is shown as the fifth limiting support piece 124 in the figure. The width of the fifth limiting support piece 124 is greater than the width of the fifth support connecting rib 126, and a clamping space for clamping the decorative panel 5 is formed between the fifth limiting piece 125 and the fifth limiting piece 125.

[0140] Since the fifth supporting connecting rib 126 is centrally located between the fifth limiting support pieces 124 and also centrally located relative to the fifth limiting piece 125, two clamping spaces are formed.

[0141] based on Figure 14 The exemplified dry-hanging component is relative to Figure 11 The illustrated dry-hanging components are equivalent to having a supporting connection at each of the two opposite edges of a relatively larger base plate.

[0142] in addition, Figure 12 The dry-hanging component shown is relative to Figure 14 The example dry-hanging component is equivalent to having an additional baffle 103. Figure 12 The exemplified dry-hanging fitting can be used for the installation of the outermost trim panel 5.

[0143] In addition, the dry-hanging piece located on the outermost side can be located at the corner of the trim panel 5 or at the center of the outermost edge of the trim panel 5.

[0144] like Figure 1 As shown, due to the presence of the fixing plate 1, there is often a certain distance between the keel 3 and the base wall. This distance is sufficient to allow for the installation of the dry-hanging parts located on the outermost side after the decorative panel 5 is installed.

[0145] In addition, regarding the fit between the limiting piece and the decorative panel 5, as mentioned above, it can be the fit between one edge of the sheet-like limiting piece and the decorative panel 5, or the fit between the end face of a rectangular or circular portion formed by winding a sheet-like limiting part and the decorative panel 5.

[0146] Given that the dry-hanging parts with sheet metal features are clearly shown in the accompanying drawings of this utility model embodiment, and given that this utility model embodiment provides a preferred method of forming by stamping, those skilled in the art can determine how to form the corresponding dry-hanging parts by stamping without creative effort, and will not elaborate further.

[0147] Given the detailed explanation of the dry-hanging components above, including their relationship with trim panel 5, the trim system will not be described in detail here.

[0148] It should be noted that the finishing system based on the present invention does not require the gaps between the finishing panels 5 to be filled. In the preferred embodiment, the gaps between the finishing panels 5 can be retained, thereby enabling the finishing system to have ventilation capabilities and reducing wind load.

[0149] exist Figure 4 The illustrated structure shows transverse seams 8 and longitudinal seams 9. Transverse seams 8 are mainly determined by the supporting connection part, and will not be described in detail here. Longitudinal seams 9 require manual control, and the seam width is generally 3~5mm.

[0150] Regarding the application of the aforementioned finishing system in architecture, it is mainly used as an exterior wall finishing system, but it can also be used as a wall finishing system or a ceiling finishing system.
