Description

Technical Field

[0001] The present invention relates to a dry hanging part for installing decorative panels, a decorative surface system formed by installing decorative panels with the dry hanging part, and a building with the decorative surface system. Background Art

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

[0003] The known dry hanging method generally requires pre-grooving on, for example, a stone veneer, and the hanger has a hook that matches the groove on the stone veneer, so as to be fixed between the base frame and the wall. The base frame is generally a light keel. Since light keels are mostly made of hot-dip galvanized steel, they are often called light steel keels, but are not limited to steel. Currently, aluminum alloy keels are also widely used in the installation of veneer panels in the construction industry.

[0004] It should be further explained that, currently, the installation of veneers on walls with the aid of, for example, hangers does not necessarily require the use of a base frame for installation. In some implementations, the installation of veneers can also be achieved with the aid of hangers pre-embedded in the base wall.

[0005] Furthermore, in some implementations, the method of pre-embedding the hangers into the base wall is adopted. The hangers have two groups, one group is used to support the decorative panel from the bottom side, and the other group is used to hook the decorative panel from the top side, and grooves are required on both the upper and lower sides of the decorative panel. Since most decorative panels are made of hard and brittle materials such as stone, stress concentration will be formed at the grooved part after grooving, and it is easy to collapse at the grooved part, especially the relatively fragile side parts. However, the current grooves on the decorative panels are mainly grooved at the side parts of the sides of the decorative panels.

[0006] In view of this, in some implementations, the slot is offset to the inside of the board. In such implementations, the slot is generally opened on the inner surface of the decorative panel, and the distance between the slot and the upper edge or lower edge of the decorative panel is mostly 50~100mm, thereby avoiding the relatively fragile edge. However, when the slot is opened on the inner surface of the decorative panel, the reliability of the hooking of the decorative panel needs to be considered. Therefore, the corresponding slot is often an oblique slot in the form of a blind hole inclined upward. The initial cutting difficulty of the slot is relatively large, and the corresponding hanger needs to be hooked to the decorative panel. In such implementations, the installation of the decorative panel is also relatively difficult, because the slot is located on the back of the decorative panel, it will be blocked by the decorative panel itself during installation, and the alignment of the slot and the hanger is relatively difficult. The installation efficiency is relatively low, and it is not easy to identify whether the hanger is hung in place, and there may be problems with assembly reliability that are difficult to detect.

[0007] Furthermore, in recent years, a method of installing decorative panels with the help of back bolts has emerged, that is, back bolts are installed on the decorative panels in advance, and the decorative panels are installed on the base frame with the help of nuts on site. This method faces the same dilemma as grooving on the back of the decorative panels, that is, it is often difficult to find the bolt holes on the base frame corresponding to the back bolts when installing the decorative panels. At the same time, due to the obstruction of the decorative panels, the locking between the back bolts and the corresponding nuts needs to be completed in the space between the decorative panels and the wall, and the installation tools are difficult to deploy, which seriously affects the installation efficiency of the decorative panels.

[0008] All the above decorative panels need to be grooved on the decorative panels, including the back bolts, which also need to be grooved, which will cause local damage to the decorative panel matrix and affect the strength of the decorative panel itself. At the same time, the grooves of the decorative panels will correspond to the groove process, and the overall efficiency is low. Summary of the invention

[0047] It should be known that the 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, so the decorative surface of the decorative panel 5 is also called the outer surface, and the back surface is also called the inner surface. The inner surface is usually invisible in the installed state of the decorative panel 5.

[0048] In relatively many applications, the decorative panel 5 is usually installed in a vertical manner, so that in the installed state, the decorative panel 5 has definite up, down, left, and right directions.

[0049] It should also be noted that, since the decorative panel 5 is not necessarily installed in a vertical manner, in some applications, the decorative panel 5 can be installed in a horizontal manner, such as a decorative panel 5 for a suspended ceiling, which uses a substantially horizontally arranged base frame to construct a suspended ceiling decorative surface. However, for the sake of uniform description, the example based on the aforementioned vertical installation state is used to characterize the installation state of the decorative panel 5, and the upper and lower sides of the decorative panel 5 are only used here to describe the two opposite sides of the decorative panel 5, and do not have the meaning of the upper and lower positions in space.

[0050] Although the decorative panel 5 has a certain thickness, for example, it is a rectangle with a certain thickness, and therefore, it has four sides, people are more accustomed to using the word "edge" to represent the side of the decorative panel 5, which is a general naming method for panels and will not cause ambiguity.

[0051] Regarding the thickness of the decorative panel 5, the thickness range is 3mm~50mm. The dry hanging parts according to the embodiment of the present invention are mainly used for the installation of decorative panels 5 with a thickness less than or equal to 25mm, and mainly relatively thin decorative panels 5, such as decorative panels 5 with a thickness less than or equal to 15mm.

[0052] In some embodiments, the dry hanging parts can be customized according to the thickness of the installed decorative panel 5, while in other embodiments, the dry hanging parts can have a relatively large application range, such as Fig.11The double-card middle piece 4 shown in the figure has a second spring 44 , and thus has a certain adaptability to the thickness range of the decorative panel 5 .

[0053] As described in the background technology section, the decorative panels 5 suitable for known dry hanging parts generally require grooves or holes to be opened on the decorative panels 5 , which increases the difficulty of processing the decorative panels 5 suitable for such dry hanging parts and also reduces the strength of the decorative panels 5 themselves.

[0054] In the embodiment of the present invention, the dry hanging parts provided do not need to be grooved 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 and hooking the outer surface of the decorative panel 5, thereby improving the installation efficiency and reducing damage to the decorative panel 5.

[0055] See also Figure 8~Figure 14 The various examples of dry hanging parts shown have a bottom plate, such as Figure 8 The first bottom plate 26 shown in the figure is a flat plate structure, and may also have other shapes, but the main part of the flat plate structure is preferred. The main consideration for using other shapes is to improve the overall rigidity. For example, Figure 8 In the embodiment, the first bottom plate 26 may have reverse folded flanges on the left and right sides, and the flanges are roughly parallel to the left and right sides of the keel 3 and will not cause assembly interference. However, the existence of the flanges will greatly improve the rigidity of the first bottom plate 26.

[0056] exist Figure 8 In the illustrated structure, three rivet holes 27 are opened on the first bottom plate 26 , so that the first bottom plate 26 can be riveted to the keel 3 by means of the rivet holes 27 .

[0057] Riveting is a static connection and a non-detachable connection, so the reliability of fixation is relatively high.

[0058] In some implementations, bolting can also be used to achieve the installation of dry hanging parts, but as a secondary option, it will not be described in detail here.

[0059] Figure 1 The illustrated structure is an example of a dry hanging part using the base frame as the installation base, but it should be known that in some applications, the decorative panel 5 can be directly installed on the base wall without setting the keel 3, such as pre-embedding a given number of anchor bolts on the base wall, and installing the decorative panel 5 using the anchor bolts as the base. As for the embedded parts such as anchor bolts used for directly installing the decorative panel 5, other embedded parts can also be used, which is conducive to embedding panels, blocks, etc., and only needs to expose the parts used for connecting, for example, the first bottom plate 26.

[0060] If the base frame is used as the installation base, the bottom plate of the dry hanging part mainly uses the longitudinal keel in the base frame as the installation base, and in some embodiments, the transverse keel can also be used as the installation base. The corresponding keel 3 can be pre-drilled, or it can be drilled on site according to the size of the building, such as the outer wall.

[0061] In view of the complicated situation on site, for the decorative panel 5, in addition to the fixed size adaptation, it is also common in the art to cut and install part of the decorative panel 5. However, it should also be known that, for example, the exterior wall of a building is constructed according to the design specifications, and its size error is generally not large. For the base frame, its construction actually takes into account the construction error of the base wall and makes adjustments. The dry hanging parts installed on the base frame are further set out based on the drawing size of the decorative panel 5 installation, and the dry hanging parts are installed on the base frame, which can have good size adaptability with the decorative panel 5. It should be noted that the dry hanging parts according to the embodiment of the present invention do not need to be grooved in advance on the decorative panel 5. In other words, they are more adaptable to the size of the decorative panel 5, and do not need to adjust the horizontal position of the dry hanging parts on site, so they have a higher installation efficiency. In contrast, for the known pre-grooved decorative panel 5, the dry hanging parts often need to be frequently adjusted because they need to be aligned with the grooves, which further reduces the installation efficiency of the decorative panel 5.

[0062] See also Figure 2 In the figure, the first bracket 2 has no lateral constraints. Therefore, when the decorative panels 5 of the same specification change in size due to processing errors (generally small), there is no lateral constraint. For example, the first bracket 2 does not need to adjust the installation position of the first bracket 2 on the keel 3 at least in the lateral direction, thereby improving the installation efficiency of the decorative panels 5.

[0063] Correspondingly, the known dry hanging parts often need to use, for example, elongated holes to meet the fine adjustment required when the dimensional accuracy and assembly accuracy are insufficient.

[0064] And if Figure 7 As shown, for example, the first bracket 2 can be pre-fixed on, for example, the keel 3, and unlike traditional dry hanging parts, the dry hanging parts need to be installed under the shielding state of the decorative panel 5. Therefore, based on the relatively high construction efficiency of the dry hanging parts of the embodiment of the present invention, the reliability of its installation is also relatively easy to ensure.

[0065] In a preferred embodiment of the present invention, the dry hanging parts are formed by stamping sheet metal, and the thickness of the sheet metal used is 0.3 mm to 2 mm, which can be selected according to different decorative panels 5, specifically the maximum weight of a single decorative panel 5.

[0066] Regarding the choice of dry hanging materials, the main ones are galvanized steel SECC, hot-dip galvanized steel SGCC, stainless steel, etc. These sheet metals have relatively good corrosion resistance and have a certain toughness, so they can form Figure 8 The first reed 21 shown in FIG.

[0067] Regarding the selection of stainless steel, SUS301 and SUS304 are mainly used, among which SUS301 with relatively better elastic performance is preferred.

[0068] Regarding the dry hanging parts based on the embodiments of the present invention, they are mainly formed by stamping. It should be known that the consistency of workpieces manufactured by stamping and other forming methods with the help of molds is better, that is, the dimensional consistency is relatively good and the interchangeability is better. Therefore, it is more suitable for the production of dry hanging parts.

[0069] The bottom plate of the dry hanging part is a base plate, which is used to connect the dry hanging part with, for example, the keel 3 or a component pre-embedded in the base wall as mentioned above. The connection method preferably adopts riveting with relatively good reliability, such as Figure 2 and Figure 3 Riveting such as rivets 6 is used. In some embodiments, welding can also be directly used. In this case, it is not necessary to open rivet holes 27 on the bottom plate in advance. Spot welding, segment welding or full welding can be used on site according to the determined installation position. The main consideration is that it is often unnecessary to adjust the dry hanging parts according to the size 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.

[0070] If, for example, riveting is used, the corresponding Figure 8 The number of the rivet holes 27 is three, and the three rivet holes 27 are arranged in an isosceles triangle, so as to improve the reliability of fixing.

[0071] Figure 8 and Fig. 9 The illustrated dry hanging parts are relatively small in size and mainly provide support functions, and the number of rivet holes 27 adapted thereto is relatively small. Fig.10 In the illustrated dry hanging part, six rivet holes 42 are opened on the second bottom plate 45. The six rivet holes 42 are arranged in three rows, and the distance between the two rivet holes 42 in the middle row is relatively large, thereby forming relatively good assembly reliability.

[0072] exist Fig.12 and Fig.14 In the illustrated structure, the dry hanging parts shown are mainly dry hanging parts with relatively small size specifications, such as Fig.12 The dry hanging piece shown in FIG. 1 is adapted with three rivet holes 109, and Fig.14 The dry hanging piece shown in the figure also has three rivet holes 128. Fig.12The three rivet holes 109 and Fig.14 The rivet holes 128 shown in FIG. 1 are also arranged in isosceles triangles.

[0073] exist Fig.13 In the illustrated structure, there are four adapted 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, and the overall distribution is also an isosceles triangle.

[0074] Regarding the keel 3, light gage steel joist is mainly used. The light gage steel keel DC50×15×1.5 GB11981 for construction can be selected, or other light gage steel keels for construction can be selected, including ceiling keels.

[0075] In an embodiment of the present invention, the load-bearing keels of the light steel keels forming the base skeleton are mainly groove-type light steel keels. The groove-type light steel keels can be interconnected or independent of each other. If interconnected, they are mainly interconnected by T-type keels. The T-type keels constitute the transverse keels, and the aforementioned groove-type light steel keels constitute the longitudinal keels.

[0076] The transverse keel may also be a groove-type light steel keel, which may be used as a mounting base for dry hanging parts, so that a plurality of dry hanging parts may be distributed at, for example, the bottom edge of the decorative panel 5 according to the site conditions and the specifications of the decorative panel 5 .

[0077] Based on the principles of the present invention, the installation of the decorative panel 5 is mainly achieved by means of the support of the dry hanging parts (hereinafter referred to as the lower dry hanging parts) located at the lower edge of the decorative panel 5 and the upper limit and positioning of the dry hanging parts (hereinafter referred to as the upper dry hanging parts) located at the upper edge of the decorative panel 5, as well as the cooperation between the limit parts on the upper and lower dry hanging parts and the outer surface of the decorative panel 5.

[0078] The above-mentioned upper and lower hanging parts are mainly named based on the decorative panel 5 for reference, but Figure 3 and Figure 4 The middle piece 4 shown in the figure is used as both an upper dry hanging piece and a lower dry hanging piece. At this time, the dry hanging piece itself is used as a basic reference.

[0079] Based on the foregoing description of the principles of the present invention, it can be seen that, in the installed state, the limiting portion of the dry hanging component will be exposed, but because its individual size is relatively small, it has little impact on the overall visual effect of, for example, an exterior wall.

[0080] It should be noted that the strength of the decorative panel itself is relatively large, such as stone decorative panels, which is also the main reason why hook-type dry hanging parts are commonly used to install stone decorative panels. For the dry hanging parts based on the embodiments of the present invention, the size of the limit part does not need to be too large, such as Figure 3 , Figure 4 The representation used by middleware 4 in Fig.11 The second limiting piece 43 in the embodiment, under the condition that the length of the part used to cooperate with the outer surface of the decorative panel 5 is 5~16mm, considering the dimensional accuracy of the decorative panel 6, for example, the length of the part of the second limiting piece 43 located on the side of the second limiting piece 43 connected to the support rib 47 (hereinafter referred to as the sub-limiting piece) is more than 8mm, and generally should not be too large, which will cause waste of materials, and is generally not greater than 12mm. Under this condition, the part of the dry hanging part exposed on the outside of the decorative panel 5 is relatively small, and as mentioned above, the dry hanging part is preferably a stamping part, and the main part of the limiting piece constituting the limiting part is in sheet shape, which is relatively small in visual effect. At the same time, its own size is relatively small relative to the decorative panel 5, and has little impact on the overall visual effect.

[0081] Even if it will affect the overall visual effect, as mentioned above, the dry hanging parts are often arranged regularly, and the arrangement of the corresponding exposed limiting parts must also be regular, and the regular arrangement itself often has a relatively good visual effect.

[0082] The main function of the limiting part is to provide a normal constraint on the decorative panel 5 to prevent the decorative panel 5 from falling outward. Under ideal conditions, when the decorative panel 5 is kept in a vertical state, no horizontal force will be generated. The limiting part is mainly used to prevent the decorative panel 5 from falling outward or tipping over.

[0083] It should be known that the decorative panel 5 is affected by the installation accuracy and actual factors such as wind load, which will produce an outward force, but the outward force is still relatively small compared to the deadweight of the decorative panel 5. The limiting part is mainly in the working position with the help of the pulling effect generated by the connection between the limiting part and the base plate.

[0084] It is obvious that the bottom plate must be located on the inner side of the decorative panel 5, and the limiting part must be located on the outer side of the decorative panel 5, and the bottom plate is the base of the dry hanging part, and the limiting part needs to be directly or indirectly connected to the bottom plate. In the embodiment of the present invention, the limiting part is connected to the bottom plate through a supporting connection part, and the supporting connection part is located on one side of the limiting functional part of the limiting part, so that a U-shaped opening structure is formed between the limiting functional part of the limiting part, the supporting connection part and the bottom plate, and adapted to the side of the decorative panel 5, the bottom plate directly or indirectly forms a positioning and limiting position for the inner surface of the decorative panel 5, and the limiting part forms a limit position for the outer surface of the decorative panel 5.

[0085] from Figure 2 and Figure 7 ,as well as Figure 4 and Figure 6It can be seen that the part constituting the supporting connection portion in the figure is also used to support the decorative panel 5 from the lower side or to provide positioning and limiting for the decorative panel 5 from the upper side. Therefore, the supporting connection portion is a multiplexed structure, that is, it is used for both the connection between the limiting portion and the base plate and the supporting or positioning and limiting of the decorative panel 5.

[0086] Figure 8 In the embodiment, the first vertical plate 24 constitutes a supporting connection portion. Figure 8 The upper end of the middle is punched out to form two first limiting pieces 25 constituting the limiting portion, and the lower end of the supporting connection portion is connected to the first bottom plate 26. In a preferred embodiment, the supporting connection portion and the bottom plate are bent through a sheet metal piece to form an integral connection.

[0087] Figure 8 The illustrated dry hanging parts mainly support the veneer panel 5 from the bottom, and are generally used as the bottom support of the veneer panel 5 located at the bottom of the veneer system, wherein the first vertical plate 24 is used to support the bottom edge of the veneer panel 5 .

[0088] At the same time, from Figure 8 As can be seen in FIG. 1 , the first vertical plate 24 is also used to connect the first limiting plate 25 and the first bottom plate 26. Figure 2 As shown in the figure, the keel 3 is a longitudinal keel, which is constructed on the outer wall of the building and is vertically arranged. The first bottom plate 26 of the first bracket 2 installed on the keel 3 by rivets 6 is in a vertical state, and the first vertical plate 24 is located at the lower edge of the first bottom plate 26 and extends vertically outward to form a horizontal plate. Figure 2 The decorative panel 5 is supported from below to form a support plate. At the same time, the end of the first vertical plate 24 extending outward has a pair of first limiting pieces 25. Figure 2 As can be seen in the figure, the first limiting piece 25 cooperates with the outer surface of the decorative panel 5, thereby hooking and pulling the decorative panel 5 from the outside.

[0089] Fig.11 A dual card middleware 4 is shown. Figure 6 is a schematic diagram of the fixing structure of the dual card middleware 6 on the keel 3, and Figure 1 , Figure 3 and Figure 4 The schematic diagram of the state of the double-card middleware 6 dry hanging the decorative panel 5 is shown. It can be seen from these example figures that the double-card middleware 6 has a second bottom plate 42, which is a flat plate in these example figures. When in use, it is fixedly installed on, for example, the keel 3. If the keel 3 is a longitudinal keel, the second bottom plate 42 is a vertical plate when installed.

[0090] Furthermore, a connecting support rib 47 constituting the supporting connection portion is provided on the left and right sides of the second bottom plate 42. Figure 3 and Figure 4As can be seen from the illustrated structure, the upper side of the connecting support rib 47 is used to support the decorative panel 5 located on the upper side thereof, and the lower side of the connecting support rib 47 provides an upper limit and positioning for the decorative panel 5 located therebelow. Therefore, the double-card middle piece 4 is a double-acting dry hanging piece for the decorative panel 5. Figure 4 As can be seen in the figure, it can be used to position or limit the four decorative panels 5.

[0091] The second stopper 43 located at the top of the supporting connecting rib 47 extends downward in the figure to form a lower stopper, which is used to cooperate with the outer surface of the decorative panel 5 located at the lower side, and hook and pull the corresponding decorative panel 5 from the upper end. Correspondingly, the second stopper 43 located at the top of the supporting connecting rib 47 extends upward in the figure to form an upper stopper, which is used to cooperate with the outer surface of the decorative panel 5 located at the upper side, and hook and pull the corresponding decorative panel 5 from the lower end.

[0092] From the above content, it can be seen that both the first vertical plate 24 and the connecting support rib 47 are roughly vertically connected to the corresponding bottom plate, so as to provide a supporting or pressing function, and cooperate with the lower edge or upper edge of the decorative panel 5 to form upper and lower limits or positioning.

[0093] The second limiting piece 43, for example, located at the end of the connecting support rib 47, extends to both sides of the connecting support rib 47, and leaves the connecting support rib 47 in the normal direction (thickness direction) of the decorative panel 5, so as to Fig.11 As shown, a roughly U-shaped structural portion, namely a U-shaped opening structure, is formed on both sides of the connecting support rib 47, and cooperates with the inner and outer surfaces of the decorative panel 5 to form a locking of the decorative panel.

[0094] For example, the connecting support rib 47 is connected to the second bottom plate 45 in a substantially vertical manner. Figure 8 In the illustrated structure, the first vertical plate 24 and the first bottom plate 26 are approximately perpendicular, and the angle between the two may not be equal to 90°, but there is an angle relative to the vertical state. When 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.

[0095] As mentioned above, since sheet metal such as stainless steel has relatively large rigidity, the angle between the first vertical plate 24 and the first bottom plate 26 should not be greater than 3° when deviated from the vertical state.

[0096] Regarding the limiting part, in the structure illustrated in the drawings of the specification, a sheet structure is mainly adopted. In the preferred embodiment of the present invention, the dry hanging parts are mainly sheet metal stamping parts, and the sheet structure is easy to construct.

[0097] In some embodiments, for example Figure 8The first limiting plate 25 shown is located at the upper end of the first vertical plate 24 in the figure. The width of the first vertical plate 24 is 50mm~85mm. Two base plates are formed by punching. The base plates are 30mm in length after vertically bending toward one side of the first vertical plate 24, and the effective length is 8mm as mentioned above. Therefore, a rectangular or circular structure can be formed by, for example, winding or multiple bending. The rectangular or circular structure cantilevers relative to, for example, one side of the first vertical plate 24, and can cooperate with the outer surface of the decorative panel 5.

[0098] If the processing precision of the decorative panel 5 is relatively high, even under the condition of considering thermal expansion and contraction, for example, the effective length of the first limit piece 25 reaches 8 mm, which can fully meet the use requirements. And under the condition of relatively high processing precision of the decorative panel 5, the effective length of the first limit piece 25 can be even shorter.

[0099] The effective length here refers to, for example, the length of the first limiting piece 25 vertically overhanging toward one side of the first vertical plate 24. The same is true for other limiting parts.

[0100] Regarding the limiting part, it can extend to one side of the supporting connection part or to both sides of the supporting connection part relative to the supporting connection part to adapt to different applications. The extension is preferably vertically extended. The limiting part and the supporting connection part form a hook structure. Obviously, based on the hooking of the decorative panel 5, it is determined that the limiting part does not necessarily need to extend vertically relative to the supporting connection part.

[0101] Correspondingly, if the limiting portion extends toward one side of the supporting connection portion, the supporting connection portion is used to support the lower edge of the decorative panel 5, for example Figure 8~Figure 10 In the illustrated first bracket 2 , the first limiting piece 25 extends toward one side of the first vertical plate 24 , thereby forming a single-sided U-shaped opening structure with the first bottom plate 26 .

[0102] and Fig.11 , Fig.12 and Fig.14 The illustrated dry hanging member, for example, the second limiting piece 43 extends in two opposite directions relative to the connecting support rib 47, thereby forming a U-shaped opening structure on both sides.

[0103] Furthermore, when the U-shaped opening structure is provided on both sides, for example, the support ribs 47 are connected, which are used for both support and upper limit and positioning, and thus can be used as Figure 3 and Figure 4 The double-card middle piece 4 shown in the figure is used for installing four decorative panels 5.

[0104] In addition, for example, for the first bracket 2, Figure 1 and Figure 2In the illustrated structure, the decorative panel 5 is supported at the corners. Considering that the decorative panel 5 located at the bottom may bear a greater load due to, for example, the load-bearing force of the connecting support ribs 47 on the double-card middle piece 4 located on the upper side, in addition to using, for example, the first bracket 2 for support at the corners, the decorative panel 5 located at the bottom can also be separately configured with a first bracket 2 located in the middle or on both sides of the middle. Under this condition, the first bracket 2 located at the two corners can also be omitted.

[0105] For the convenience of description, the space between the limiting portion and the bottom plate is referred to as a clamping space.

[0106] In a preferred embodiment, the bottom plate has a spring sheet so that the clamping space has a clamping margin. Fig.13 Except for the dry hanging parts shown in the example, the other dry hanging parts examples all have reeds. Fig. 9 and Fig.10 The dry hanging parts shown are used as an example for explanation, and the other dry hanging parts can be applied by reference.

[0107] exist Fig. 9 and Fig.10 In the illustrated structure, two first reeds 21 are formed directly on the first base plate 26 based on a punching process. Fig.10 It is shown in the figure that in the initial state, in the normal direction of the first base plate 26, there is an initial clamping distance h between the first spring piece 21 and the first limiting piece 25, and the initial clamping distance h is less than the thickness of the decorative panel 5. Therefore, when the decorative panel 5 is installed using such dry hanging parts, the first spring piece 21 is compressed by the decorative panel 5 toward the first base plate 26, and the generated rebound force can ensure that the decorative panel 5 is reliably restrained and does not move freely.

[0108] If we simply rely on hard limits, due to the influence of processing accuracy and assembly accuracy, there will be a certain amount of movement space between the decorative panel 5 and the corresponding functional components of the dry hanging parts. Under the influence of wind, for example, the decorative panel 5 will produce a certain amount of movement in the inward and outward directions, which may easily generate fatigue loads and then fatigue cracks, which may reduce the service life of the decorative panel 5.

[0109] With the help of the spring, the influence of processing accuracy and assembly accuracy can be overcome, and the decorative panel 5 can be more reliably bound to, for example, the base frame.

[0110] In addition, as mentioned above, affected by the processing accuracy and assembly accuracy, simply relying on hard limits often does not provide sufficient restraint under the condition of rapid assembly, or is difficult to assemble under the condition of sufficient restraint. The presence of the spring can provide an appropriate amount of margin, thereby effectively restraining the decorative panel 5 while achieving rapid installation of the decorative panel 5, and has better application prospects.

[0111] The amount of movement of the spring in the normal direction of the first base plate 26 is preferably not greater than 8 mm, and generally not less than 3 mm.

[0112] Regarding the shape of the reed, such as Fig. 9 and Fig.10 The first reed 21 shown in the figure is a warped sheet-like body as a whole. Generally, it can be directly punched out by a punch, so that a first cutout 23 is formed on, for example, a first bottom plate 26, and the first reed 21 is formed by the turned-up first bottom plate portion.

[0113] As mentioned above, the dry hanging device according to the embodiment of the present invention is suitable for the decorative panel 5 to slide in from one side. Therefore, the warped spring leaves, such as the first spring leaf 21, are conducive to manually assisting in pressing the spring leaves, which facilitates the decorative panel 5 to slide in from one side.

[0114] In e.g. Fig. 9 In the illustrated structure, the main part of the first spring piece 21 warped relative to the first bottom plate 26 is a rectangular piece, and the angle between the rectangular piece and the first bottom plate 26 is 15° to 45°, preferably not greater than 30°.

[0115] The main body end of the first spring 21 is connected to an arched portion, that is, it is bent opposite to the side where the first bottom plate 26 is located, thereby forming a dome, which is not easy to scratch the back of the decorative panel 5, or the friction is relatively small, which is conducive to the installation of the decorative panel 5.

[0116] The main body of the reeds such as the first reed 21 formed by the punching process is connected to the first bottom plate 26 and then extends obliquely upward to form an arched portion at the end to form a transition arc, thereby reducing friction resistance with the back of the decorative panel 5.

[0117] At this time, a clamping capability with a certain elastic margin is formed between the elastic spring leaf and the corresponding limiting portion, so that the decorative panel 5 can be reliably restrained.

[0118] In order to form the aforementioned matching relationship between the spring and the limiting part, the number of the functional parts of the limiting part for limiting and the number of the springs can be one-to-one or one-to-many, but the number of the springs should not be too many, generally the same as the number of the functional parts of the limiting part for limiting or twice the number of the functional parts. Under this condition, a dry hanging piece is adapted to at least one spring corresponding to a decorative panel 5, but usually no more than two springs.

[0119] from Fig. 9 and Fig.10 It can be seen from the illustrated structure that the spring and the limiting part are not necessarily directly aligned, but have a certain alignment deviation, which is mainly used to avoid forming interference. Regarding the supporting connection part, two forms are mainly proposed in the embodiments of the present invention. One is a plate structure, such as Figure 8 and Fig. 9 In the first vertical plate 24 shown in FIG. , and in more embodiments, as shown in FIG. Fig.11 , Fig.12 and Fig.14 For example, the connecting support ribs 47 shown in FIG. 4 are of a slatted structure as a whole.

[0120] It should be known that in the field of mechanics, a slat structure refers to a plate body with a relatively large aspect ratio, such as a rectangular plate with an aspect ratio greater than or equal to 2.

[0121] If it is a plate-type structure, the dry hanging member is used as a support member for supporting the decorative panel 5; accordingly, Fig. 9 As shown, the first limiting piece 25 constituting the limiting part is located at the end of the extension of the plate-like structure part, and has a pair of first limiting pieces 25, and the corresponding two first limiting pieces 25 are located at both ends of the end of the plate-like structure part. In addition, Fig. 9 In the figure, the ends of the first vertical plate 24 extending vertically outward relative to the first bottom plate 26 are rounded at both ends, and the rounded corners further extend toward the first limiting plate 25, so that the first limiting plate 25 also presents a semi-bow structure. The smooth connection reduces the sharp parts and makes the first limiting plate 25 more beautiful.

[0122] Fig.14 The dry hanging parts shown are equivalent to Fig.11 The illustrated half structure of the dry hanging part is used for installing the decorative panel 5 located on the side. Fig.14 In the figure, one side where the fifth base plate 122 is connected to the fifth supporting connecting rib 126 has a flange portion, which is represented as the fifth limiting support plate 124. The width of the fifth limiting support plate 124 is greater than the width of the fifth supporting connecting rib 126, and a clamping space for clamping the decorative panel 5 is formed between the fifth limiting support plate 124 and the fifth limiting support plate 125.

[0123] Since the fifth supporting connecting rib 126 is centrally disposed between the fifth limiting supporting pieces 124 and is also centrally disposed relative to the fifth limiting piece 125 , two clamping spaces are formed.

[0124] based on Fig.14 The dry hanging parts shown are relative to Fig.11 The relationship of the illustrated dry hanging parts is equivalent to providing a supporting connection portion on two opposite edges of a relatively larger base plate.

[0125] in addition, Fig.12 The dry hanging parts shown are relative to Fig.14 The dry hanging part shown in the example is equivalent to having an additional baffle 103. Fig.12 The illustrated dry hanging parts can be used for the installation of the decorative panel 5 located at the outermost side.

[0126] In addition, the dry hanging piece located at the outermost side may be located at the corner of the decorative panel 5 , or may be located at the middle of the outermost edge of the decorative panel 5 .

[0127] like Figure 1 As shown, due to the existence of the fixing plate 1, there is often a certain distance between the keel 3 and the base wall, and this distance can fully meet the installation of the dry hanging parts located at the edge after the decorative panel 5 is installed.

[0128] In addition, regarding the cooperation between the limiting plate and the decorative panel 5, as mentioned in the previous article, it can be the cooperation between an edge of a sheet-shaped limiting plate and the decorative panel 5, or it can be the cooperation between the end face of a rectangular or circular part, for example, formed by winding a sheet-shaped limiting part and the decorative panel 5.

[0129] In view of the fact that the dry hanging parts with sheet metal features are clearly shown in the drawings of the embodiments of the present invention, and the conditions under which stamping is preferably adopted in the embodiments of the present invention, technicians in this field can determine how to stamp out the corresponding dry hanging parts without creative work, and no further details are given.

[0130] Since the dry hanging parts have been described in detail in the foregoing text, including the relationship with the decorative panel 5, the decorative system will not be described in detail here.

[0131] It should be additionally noted that the facing system based on the embodiment of the present invention does not require the gaps between the facing panels 5 to be filled, and in a preferred embodiment, the gaps between the facing panels 5 can be retained, so that the facing system has ventilation capabilities and reduces wind loads.

[0132] exist Figure 4 The illustrated structure shows a transverse plate seam 8 and a longitudinal plate seam 9, wherein the transverse plate seam 8 is mainly determined by the supporting connection part, which will not be described in detail. The longitudinal plate seam 9 needs to be manually controlled, and the seam width is generally 3-5 mm.

[0133] Regarding the application of the finishing system in architecture, it is mainly used as an exterior wall finishing system, and can also be used as a wall finishing system, and can also be used as a ceiling finishing system.
