Description

Technical Field

[0001] The present invention relates to the field of architectural design, in particular to a modular building. Background Art

[0002] Building structures are typically composed of walls and roofs. With the advancement of construction technology, modular walls are becoming increasingly common. These walls can be quickly assembled, meeting the requirements for efficient construction. However, current walls have several drawbacks, including the large number of connecting parts and the heavy frames surrounding the edges, which lack a light and aesthetically pleasing appearance. Furthermore, the walls are weak in strength and structurally unstable, making them unsafe for use. Summary of the Invention

[0003] Based on the above problems, it is necessary to provide a modular building.

[0004] A modular building comprising:

[0005] A frame structure, wherein the frame structure comprises a plurality of frame profiles connected end to end, wherein the frame profiles are respectively provided with first mounting grooves on two side surfaces along the thickness direction of the hidden frame curtain wall structure, and the first mounting grooves of the two connected frame profiles are connected; the frame profiles form a first abutment surface and a first enclosure surface at a portion close to the outer edge of the frame structure, the first abutment surface and the first enclosure surface are sequentially arranged in a direction gradually away from the center of the frame structure, the first abutment surface is flush with the notch of the first mounting groove, and the first enclosure surface faces the middle of the frame structure;

[0006] a wall panel unit comprising an inner surface and an outer facade disposed opposite to each other, the inner surface and the outer facade being connected by an edge surface, the edge of the inner surface being in contact with the first abutting surface, and the edge surface being in contact with the first enclosing surface, so that the wall panel unit is embedded in the frame structure;

[0007] A snap-on magnetic component is installed in the first installation groove, and the frame profile is adsorbed and connected to the wall panel unit through the snap-on magnetic component.

[0008] The above-mentioned modular building has at least the following beneficial technical effects:

[0009] The embedded design of the concealed frame curtain wall structure of the modular building of this embodiment enables a small thickness design of the peripheral components of the wall panel unit, which looks light and beautiful, and is flexible and convenient to install. The first abutment surface and the first blocking surface provide supporting support for the inner surface and edge surface of the wall panel unit, respectively, so that all surfaces of the wall panel unit can be simultaneously limited, and the whole can be firmly positioned and installed, thereby improving the safety of use.

[0010] By adopting the structure of the present invention, the internal connection structure cannot be seen from the outside of the entire wall structure, and the whole wall structure is neat and beautiful with good appearance quality.

[0011] By adopting the structure of the present invention, the wall panels can be quickly installed to form a wall structure. After assembly, the snap-fit ​​magnetic assembly is connected to the installation slot. The gravity load direction of the wall panel is perpendicular to the plane of the slot wall of the installation slot, and the wall panel cannot be driven to separate from the installation slot. The slot wall of the installation slot has a strong supporting and hanging force on the wall panel and the snap-fit ​​magnetic assembly. The snap-fit ​​magnetic assembly and the installation slot of the frame profile have a strong snap-fitting force and friction force after being tightly matched. The snap-fit ​​magnetic assembly is adhered to the frame profile by magnetic attraction, and the magnetic force is very strong. After the combined action, it can withstand a strong tensile load. Even if subjected to a tensile force perpendicular to the wall surface, the snap-fit ​​magnetic assembly cannot be easily separated from the frame profile. Therefore, after the snap-fitting force and the magnetic attraction force are combined, the connection strength between the wall panel and the frame structure is high and it is difficult to fall off, thereby fully ensuring safety in use.

[0012] Since the connection method between the wall panel and the frame structure is simple, installation is convenient and disassembly is also simple, which makes it easy to replace personalized wall panel units at any time. The replaced wall panel units can also be reused and will not be directly scrapped, which greatly saves resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] like Figures 1-6 As shown, in one embodiment of the present invention, a modular building is provided, including a hidden frame curtain wall structure, wherein the hidden frame curtain wall structure includes:

[0054] A frame structure 110, comprising a plurality of frame profiles 111 connected end to end, wherein the frame profiles 111 are respectively provided with first mounting grooves 1111 on both side surfaces along the thickness direction of the hidden frame curtain wall structure, and the first mounting grooves 1111 of the two connected frame profiles 111 are connected; the frame profiles 111 form a first abutting surface 1112 and a first enclosing surface 1113 at a position close to the outer edge of the frame structure 110, the first abutting surface 1112 and the first enclosing surface 1113 being arranged in sequence in a direction gradually away from the center of the frame structure 110, the first abutting surface 1112 being flush with the notch of the first mounting groove 1111, and the first enclosing surface 1113 facing the middle of the frame structure 110;

[0055] The wall panel unit 130 includes an inner surface 131 and an outer surface 132 disposed opposite to each other. The inner surface 131 and the outer surface 132 are connected by an edge surface 133. The edge of the inner surface 131 is in contact with the first abutting surface 1112, and the edge surface 133 is in contact with the first enclosing surface 1113, so that the wall panel unit 130 is embedded in the frame structure 110.

[0056] The first installation groove 1111 is installed with a snap-on magnetic component, and the frame profile 111 is adsorbed and connected to the wall panel unit 130 through the snap-on magnetic component.

[0057] Specifically, the edge of the inner surface 131 of the wall panel unit 130 is in contact with the first abutting surface 1112, and the edge surface 133 is in contact with the first enclosure surface 1113, so that the wall panel unit 130 is directly embedded in the frame structure 110. The embedded design makes it possible to design the outer peripheral components of the wall panel unit 130 with a small thickness, which is light and beautiful in appearance and flexible and convenient to install. The first abutting surface 1112 and the first enclosure surface 1113 provide matching support for the inner surface 131 and the edge surface 133 of the wall panel unit 130, respectively, so that all surfaces of the wall panel unit 130 can be simultaneously limited, and the whole can be firmly positioned and installed, thereby improving the safety of use.

[0058] The frame profile 111 itself can be made of magnetic metal or magnetic material, or a non-magnetic metal profile. A magnetic metal component or a magnetic material component is set in the first installation groove 1111, and multiple profiles are spliced ​​to form a frame structure. Depending on the installation position, the hidden frame curtain wall structure can be used as a wall panel, floor or roof panel, etc. Specifically, taking the installation of the wall panel unit 130 as an example, the snap-on magnetic component made of magnetic material is pre-fixed on the inner surface of the wall panel unit 130. When the snap-on magnetic component is assembled and embedded in the first installation groove, the first abutment surface on the side will also abut against the wall panel unit, so that the wall panel can be directly fixed to the frame profile 111.

[0059] By adopting the structure of the present invention, the internal connection structure cannot be seen from the outside of the entire wall structure, and the whole wall structure is neat and beautiful with good appearance quality.

[0060] The wall panel 10 can be quickly installed to form a wall structure by adopting the structure of the present invention. After assembly, the snap-fit ​​magnetic assembly is connected to the installation slot. The gravity load direction of the wall panel 10 is perpendicular to the plane of the slot wall of the installation slot, and the wall panel 10 cannot be driven to separate from the installation slot. The slot wall of the installation slot has a strong supporting and hanging force on the wall panel 10 and the snap-fit ​​magnetic assembly. The snap-fit ​​magnetic assembly and the installation slot of the frame profile 111 are tightly matched with each other. The snap-fit ​​magnetic assembly is adhered to the frame profile 111 by magnetic attraction, and the magnetic force is very strong. After the combined action, it can withstand a strong tensile load. Even if a tensile force perpendicular to the wall is applied, the snap-fit ​​magnetic assembly and the frame profile 111 cannot be easily separated. Therefore, after the snap-fit ​​force and the magnetic force are combined, the connection strength between the wall panel 10 and the frame structure 110 is high and it is difficult to fall off, which fully ensures safety in use.

[0061] Since the connection method between the wall panel and the frame structure 110 is simple, installation is convenient, and disassembly is also simple, it is convenient to replace the personalized wall panel unit 130 at any time. The replaced wall panel unit 130 can also be reused and will not be directly scrapped, which greatly saves resources.

[0062] In actual products, profiles are usually made of non-metallic materials such as aluminum alloy. In this case, a magnetic metal strip or magnetic strip can be set at the bottom of the installation slot to provide magnetic force. However, after testing, the magnetic force of this setting method is weak, and the magnetic metal strip or magnetic strip is a non-standard part, which is difficult to produce and is not convenient to install at the bottom of the installation slot. Therefore, reference Figure 4 In some embodiments, the snap-on magnetic assembly includes:

[0063] The snap-fitting slot 200 includes a slot bottom plate 210 and slot walls 220 provided on both sides of the slot bottom plate 210 in the width direction. The two slot walls 220 form a notch between the edges away from the slot bottom plate 210. The slot bottom plate 210 of the snap-fitting slot 200 is fixedly connected to the first mounting slot 1111.

[0064] The snap-fit ​​block 100 is inserted into the snap-fit ​​groove 200 in the same direction as the length of the snap-fit ​​groove 200, and the two side surfaces of the snap-fit ​​block 100 in the width direction are in contact with the inner wall surface of the groove wall 220. At least one of the snap-fit ​​groove 200 and the snap-fit ​​block 100 is a magnetic component, and the other is a magnetic metal part or a magnetic component.

[0065] Specifically, the snap-fitting groove 200 is pre-arranged in the first mounting groove 1111 by means of a screw 250. For example, the screw 250 can be used to pass through the groove bottom plate 210 from the inside of the snap-fitting groove 200 and screwed into the first mounting groove. The snap-fitting block 100 made of magnetic material or magnetic metal parts is arranged on one side of the inner surface of the wall panel unit. The snap-fitting block 100 can be pushed horizontally into the snap-fitting groove 200 to directly fix the wall panel to the frame structure 110.

[0066] This embodiment is easy to assemble and can adapt to the installation of non-magnetic metal profiles. The clamping groove 200 wraps the clamping block 100, with a large contact area and strong magnetic attraction. Other effects are consistent with the above technical solution.

[0067] refer to Figure 7 In some embodiments, the magnetic attraction assembly can also be configured to include a magnetic attraction plate 200a and a clamping block 100a, wherein the magnetic attraction plate 200a is disposed at the bottom of the first mounting slot, and the inner sidewalls of the mounting slot are provided with limiting strips a at positions opposite to each other, for limiting the magnetic attraction plate 200a from moving away from the slot bottom and escaping from the slot. Compared with the aforementioned Figure 3 For the solution of installing the card slot 200, the magnetic attraction is relatively weak, so it is preferred to use Figure 3 plan.

[0068] refer to Figure 4In some embodiments, the contacting surfaces of the connecting slot 200 and the connecting block 100 are provided with a magnetic layer b having a different magnetic attraction, and the thickness of the magnetic layer b is 2-5 mm. The provision of the magnetic layer not only ensures magnetic attraction, but also, because the groove walls 220 and the groove bottom 210 of the connecting slot 200 and the corresponding surfaces of the connecting block 100 are all provided with the magnetic layer b, when the connecting block 100 approaches the connecting slot 200, the combined effects of form fit and magnetic attraction easily attract the connecting block 100 to the position of the connecting slot 200, thereby embedding into the connecting slot 200 and firmly connecting to the connecting slot 200.

[0069] In some embodiments, the clamping block 100 is an elastic body composed of rubber and magnetic powder, and is interference-fitted with the clamping slot 200 .

[0070] The elastomer composited with rubber and magnetic powder has strong magnetism and elasticity. When the wall panel unit is fixed on the frame structure 110 by interference fit with the snap-in groove 200, the two side surfaces of the snap-in block 100 in the width direction are tightly fitted with the inner wall surface of the groove wall 220. The friction generated by the snap-in is very strong. Under the combined action of magnetic force and friction force, it can withstand strong tensile loads. Even if the pulling force perpendicular to the wall is very large, the snap-in block 100 and the wall panel unit 130 cannot be separated from the snap-in groove 200. The connection strength is higher and it is more difficult to fall off, and the installation is firm and reliable.

[0071] refer to Figure 4 In some embodiments, along the direction from the groove bottom plate 210 to the groove mouth, the inner wall surface of the groove wall 220 is sequentially provided with first strip grooves 221 side by side, and the cross section of each first strip groove 221 is triangular; the two side surfaces in the width direction of the clamping block 100 are sequentially provided with second strip protrusions with triangular cross sections side by side along the thickness direction. When the clamping block 100 is clamped into the clamping groove 200, the second strip protrusions are embedded in the first strip grooves 221 of the inner wall surface of the opposite groove wall 220, thereby respectively matching the shape of the inner wall surface of the corresponding groove wall 220 and fittingly assembled.

[0072] Specifically, the protrusions and grooves provided on the inner wall surface of the groove wall 220 and the two side surfaces of the clamping block 100 in the width direction make the clamping groove 200 and the clamping block 100 match each other in shape and fit tightly together, providing a blocking structure for the relative movement of the two in the direction perpendicular to the wall, thereby strengthening the clamping connection strength between the two; and the contact area between the two is larger, the friction coefficient μ is increased, and thus the friction force is stronger. When the two are clamped so that the wall panel unit 130 is fixed on the frame structure 110, it can withstand a strong tensile load. Even if it is subjected to an extremely strong tensile load perpendicular to the wall, the wall panel unit 130 and the clamping block 100 cannot be easily separated from the clamping groove 200 under the combined action of the stronger clamping force and friction force. In particular, when the clamping block 100 and the clamping groove 200 are both designed to be long strips, they have a strong ability to resist separation at all positions along the length direction, and the installation of the wall panel and the frame structure 110 is even more firmly and inseparable.

[0073] refer to Figure 4 In some embodiments, the slot wall 220 forms a slope 222 at the slot opening that slopes toward the interior of the engaging slot 200. The portions of the two side surfaces of the engaging block 100 corresponding to the slot opening in the width direction match the shape of the slope 222. The design of the slope 222 ensures a tight fit after the engaging block 100 is engaged, and also facilitates the insertion of the engaging block 100 into the engaging slot 200.

[0074] refer to Figure 4 In some other embodiments, a groove 101 is provided on one side surface of the clamping block 100 facing the groove bottom plate 210, and a second positioning groove 102 is provided on the side surface of the clamping block 100 facing away from the groove bottom plate 210 along the length direction, and the second positioning groove 102 is provided on the side surface of the clamping block 100 facing away from the groove bottom plate 210 and is located in the middle part in the width direction, for allowing the tail end of the second fixing screw 110 to be screwed into the clamping block 100 from one side of the groove 101 and pass through the second positioning groove 102 and then screwed into the wall panel 10, and for the head end of the second fixing screw 110 to be accommodated in the groove 101.

[0075] The groove 101 of this embodiment is used to accommodate the head end of the second fixing screw 110 and limit the installation position of the screw. The second positioning groove 102 is used to verify the installation position of the second fixing screw 110. If the tail end of the second fixing screw 110 does not pass through the second positioning groove 102, it means that the position of the second fixing screw 110 is deviated and needs to be reinstalled. This embodiment can improve the accuracy of the matching position of the second fixing screw 110 with the clamping block 100 and the wall panel unit 130, and prevent the second fixing screw 110 from shifting to one side in the width direction of the clamping block 100, resulting in uneven force on both sides of the width direction of the clamping block 100, causing damage and cracking, and prevent the clamping block 100 and the wall panel unit 130 from being torn and separated due to a loose connection between the clamping block 100 and the wall panel unit 130, thereby ensuring a firm and stable connection and extending the service life.

[0076] refer to Figure 3 In some embodiments, the wall surface of the first installation groove 1111 is provided with anti-slip strip grooves c arranged in sequence along the direction from the groove bottom to the groove opening.

[0077] Specifically, when the snap-fitting magnetic component is snapped together with the first mounting groove, the anti-slip strip groove c makes the snap-fitting magnetic component and the mounting groove match in shape and are completely tightly assembled, providing a blocking structure for the relative movement of the two in a direction perpendicular to the wall, thereby strengthening the snap-fit ​​connection strength between the two; and the contact area between the two is larger, the friction coefficient μ is increased, and thus the friction force is stronger. When the two are snapped together so that the wall panel unit 130 is fixed on the frame structure 110, it can withstand a strong tensile load. Even if it is subjected to a stronger tensile load perpendicular to the wall, the wall panel unit 130 and the snap-fitting block 100 cannot be easily detached from the snap-fitting groove 200 under the combined action of the stronger snap-fitting force and friction force. In particular, when the snap-fitting block 100 and the snap-fitting groove 200 are both designed to be long strips, they have a strong ability to resist separation at all positions along the length direction, and the wall panel and the frame structure 110 are firmly and inseparable.

[0078] refer to Figure 9 and Figure 10 In some embodiments, the connection portion of the two frame profiles 111 is provided with a corner code 120, including a first connecting segment 121 and a second connecting segment 122 connected to each other. The first connecting segment 121 and the second connecting segment 122 are respectively embedded in the first mounting grooves 1111 of the two connected frame profiles 111, and are fixed in the first mounting grooves 1111 by fasteners.

[0079] In the conventional frame structure 110 , angle irons are usually provided on the inner circle of the frame to connect the ends of adjacent profiles. The angle irons can be directly seen, and the connection is unstable and prone to torsional deformation.

[0080] Compared with the traditional frame design method, the corner code 120 of this embodiment is arranged between the inner surface 131 of the wall panel unit 130 and the side surface of the frame structure 110. The corner code 120 is not visible from the outside, and the overall appearance is more beautiful; the two side surfaces of the frame structure 110 in the thickness direction are fixedly connected by the corner code 120, the structure is symmetrical, and the forces on the two side surfaces of the frame structure 110 are symmetrical and balanced. The frame structure 110 is highly stable and not easily twisted and deformed, thereby ensuring that the position of the wall panel unit 130 is stable and not easily deformed, shaking or even falling off.

[0081] refer to Figure 10 In some embodiments, the first connecting section 121 and the second connecting section 122 both include inner edges and outer edges arranged on both sides in the width direction, and the outer edge and the inner edge are respectively arranged corresponding to the outer ring groove wall 1111a of the first mounting groove 1111 away from the center of the frame structure 110 and the inner ring groove wall 1111b close to the center of the frame structure 110; the outer edge of the first connecting section 121 and the outer edge of the second connecting section 122 are connected by an arc-shaped edge transition, and the inner edge of the first connecting section 121 and the inner edge of the second connecting section 122 are provided with a clearance groove 123 at the connected position.

[0082] In this embodiment, the outer edge of the first connecting segment 121 and the outer edge of the second connecting segment 122 are connected by an arc-shaped edge transition, which is convenient for embedding into the first installation groove 1111, and the inner edge of the first connecting segment 121 and the inner edge of the second connecting segment 122 are provided with a makeshift groove 123 at the connected position to provide a makeshift space, which can avoid interference with the right-angle connection position of the inner ring groove wall 1111b of the first installation groove 1111 near the center of the frame structure 110, resulting in an inability to embed into the installation groove. Even if the width of the first connecting segment 121 and the second connecting segment 122 of the manufactured angle code 120 is large, so that the gap between the inner and outer edges and the inner ring groove wall 1111b and the outer ring groove wall 1111a of the first installation groove 1111 is small after installation, it can still be smoothly installed in the installation groove.

[0083] refer to Figure 10 In some embodiments, two fastening holes 124 are provided at intervals along the length of each of the first connecting section 121 and the second connecting section 122. Specifically, screws passing through the two fastening holes 124 and screwing into the bottom plate of the first mounting slot 1111 provide a secure connection. The provision of two fastening holes 124 at intervals along the length ensures a secure and stable connection between the two frame profiles 111 after the corner bracket 120 is connected.

[0084] refer to Figure 2In some embodiments, the wall panel unit 130 is a glass panel, and a masking film 140 is provided around the edge of the outer facade 132 of the glass panel. Along the thickness direction of the glass panel, the projection of the corner bracket 120 falls within the masking film 140. Specifically, the masking film 140 is designed as an opaque film to cover the corner bracket 120, making it invisible from the outside and improving the overall appearance.

[0085] Of course, in addition to glass panels, in some other embodiments, the wall panel unit 130 can also use inorganic panels, wooden panels, metal panels, chemical panels, plastic panels or composite panels, etc., which are not limited here.

[0086] refer to Figure 11-13 In some embodiments, a cross bracing profile 150 is further included, disposed within the frame structure 110. The ends of the cross bracing profile 150 are respectively connected to two opposing frame profiles 111 on the frame structure 110. The cross bracing profile 150 forms a second abutting surface 151 on the side along the thickness direction of the hidden frame curtain wall structure, which is used to abut and support the inner surface 131 of the wall panel unit 130. In this embodiment, the second abutting surface 151 of the cross bracing profile 150 is in contact with the wall panel unit 130, providing central support for the wall panel unit 130 and preventing the central portion of the wall panel from bending and deforming under heavy loads, which could lead to damage.

[0087] refer to Figure 12-13 In some embodiments, the second abutment surface 151 is recessed at both side edges away from the center to form second mounting grooves 153. The second mounting grooves 153 are arranged along the length of the cross bracing profile 150. A protrusion 154 is provided near the center of the second abutment surface 151. The protrusion 154 is arranged along the length of the cross bracing profile 150. The surfaces of the protrusion 154 facing the two second mounting grooves 153 form second retaining surfaces 152. The protrusion 154 serves as a boundary, dividing the wall panel unit 130 into two wall panel units 134. The edge surfaces 133 of the two wall panel units 134 can respectively mate with the two second retaining surfaces 152 on either side of the protrusion 154, and the edge of the inner surface 131 mates with the second abutment surfaces 151 on either side of the protrusion 154, thereby allowing the two wall panel units 134 to be embedded in the frame structure 110.

[0088] In this embodiment, all surfaces of the two wall panel units 134 can be limited at the same time, and the whole can be firmly positioned and installed; in addition, the ridges 154 may not be provided during normal splicing and installation. At this time, the side surfaces of the two wall panel units 134 close to each other are directly spliced ​​together, which can easily scratch the edge surfaces of each other, and due to process reasons, the edges of the finished wall panel units 134 may be uneven or skewed. If they are directly spliced ​​together, the appearance looks very uneven. Therefore, the second retaining surface 152 of the surface ridges 154 not only plays the role of edge limiting, but also provides protection for the edges of the wall panel units 134 to avoid damage to the edge surfaces. At the same time, the ridges 154 extending in a straight line also play the role of highlighting contrast and modification, avoiding edge skew and defects affecting the overall appearance, so that there is no need to replace new wall panel units 134 due to edge defects, which reduces costs, and there is no need to demand to improve the edge processing accuracy of the wall panel units 134, which will lead to increased processing difficulty and cost.

[0089] An adhesive block or magnetic strip may be provided in the second mounting groove 153 , which is bonded or magnetically connected to the inner surface 131 of the wall panel unit 130 , so that the wall panel unit 130 is fixed more firmly and stably, thereby ensuring that the position of the wall panel unit 130 is stable and firm, and is not easy to deform, shake or fall off.

[0090] Furthermore, the cross bracing profile 150 is symmetrical on both sides along the thickness direction of the hidden frame curtain wall structure, so that the wall panel units 130 on both sides of the frame structure 110 can be installed and removed freely in the same way in conjunction with the cross bracing profile 150 .

[0091] In some embodiments, the aforementioned snap-on magnetic assembly can also be installed in the second mounting slot 153, through which the cross bracing profile is attracted and connected to the wall panel unit 130. Installing the snap-on magnetic assembly in the second mounting slot 153 performs similar functions to installing it in the first mounting slot, but it also secures the wall panel unit in more locations, making it more secure and less likely to deform, wobble, or fall off.

[0092] In some embodiments, the first abutting surface 1112 and / or the second abutting surface 151 are provided with a transfer coating, which is used to transfer the coating to the inner surface of the wall panel unit 130 when the wall panel unit 130 is pre-installed on the frame structure 110. Specifically, it was found during actual assembly that because the snap-on block 100 and snap-on groove 200 of the snap-on magnetic assembly are pre-installed separately and independently on the wall panel unit 130 and the installation groove, when the wall panel unit 130 is assembled to the frame structure 110, the snap-on block 100 and the snap-on groove 200 are easily misaligned, requiring rework and seriously affecting processing efficiency. When adopting the solution of this embodiment, the wall panel unit 130 is first pre-installed on the frame structure 110, and the transfer coating of the first abutting surface and / or the second abutting surface can be directly transferred to the inner surface of the wall panel unit 130, thereby leaving an imprint on the inner surface of the wall panel unit 130; after removing the wall panel unit, the clamping block 100 is installed corresponding to the imprint formed by the transfer on the inner surface of the wall panel unit 130. The position correspondence between the clamping block 100 and the clamping groove 200 is more accurate, which can realize the precise installation of the wall panel unit without the need for rework, thereby improving the assembly efficiency.

[0093] refer to Figure 12-13 In some embodiments, the cross bracing profile 150 is surrounded by a pair of side support plates and a pair of connecting plates 1504, and the side support plates include a second abutment plate body 1501, a groove wall plate body 1502 and a groove bottom plate body 1503. One side of the groove wall plate body 1502 is connected to the second abutment plate body 1501, and the other side extends toward the interior of the cross bracing profile 150 and is vertically connected to one side of the groove bottom plate body 1503. The other side of the groove bottom plate body 1503 is vertically connected to the plate surface of the connecting plate 1504, thereby forming the second mounting groove 153 together with the connecting plate 1504 and the groove wall plate body 1502. In this embodiment, the cross bracing profile 150 surrounded by a pair of side support plates and a pair of connecting plates 1504 is a hollow structure. The hollow structure can be formed by bending, welding or extrusion of the plates as a whole. The manufacturing process is simple, the process and material costs are low, and the weight is easy to transport and carry. Heating lines, insulation pads, fireproof materials, electrical connection lines and other pipelines 160 can be set inside to make the cross bracing profile 150 and the wall panels more functional, and avoid the trouble and complexity of separate wiring on the outside of the wall panels, while protecting the wiring.

[0094] Furthermore, along the thickness direction of the hidden frame curtain wall structure, the second abutting plate 1501 is flush with the same-side end of the connecting plate 1504. Specifically, the second abutting plate 1501 is flush with the second mounting groove 153. This allows the second abutting plate 1501 to provide abutting force for the wall panel unit 130, and the adhesive blocks or magnetic strips in the second mounting groove 153 can also maintain contact with the inner surface 131 of the wall panel unit 130, thereby providing a strong bonding force.

[0095] refer to Figure 13 In some embodiments, the difference between the distance L2 between the second enclosure surface 152 on the side away from the second abutting surface 151 and the connecting plate 1504 and the distance L1 between the second enclosure surface 152 on the side close to the second abutting surface 151 and the connecting plate 1504 is 2 mm. This is because, if there is no size difference between the two, the second enclosure surface 152 and the connecting plate 1504 will be parallel. When the edge surface 133 of the wall panel unit 130 is placed on the second enclosure surface 152, due to the presence of overflowing glue, the edge surface 133 cannot completely fit with the second enclosure surface 152. On the one hand, the overflowing glue will seep out from the gap between the two to the surface, making it difficult to clean and easily weathered. On the other hand, there will be a gap between the edge surface 133 and the second enclosure surface 152, affecting the appearance quality. In this embodiment, due to the 2 mm size difference, the second enclosure surface 152 is not parallel to the connecting plate 1504. When the edge surface 133 of the wall panel unit 130 is placed on the second enclosure surface 152, a reserved gap is formed between the edge surface 133, the second enclosure surface 152, and the second abutting surface 151 to accommodate the adhesive. There is no gap between the portion of the second enclosure surface 152 away from the connecting surface and the edge surface 133, and the adhesive will not overflow. The adhesive will not be exposed to external air and water vapor in the space enclosed by the edge surface 133, the second enclosure surface 152, and the second abutting surface 151, thereby reducing weathering and extending the service life. At the same time, no gaps can be seen in appearance, which does not affect the appearance.

[0096] refer to Figure 14-16In some embodiments, the frame profile 111 includes a first support plate 111a and a second support plate 111b that are sequentially arranged in a direction gradually away from the center of the frame structure 110 and are parallel to each other, and the two sides of the two support plates in the width direction are respectively connected by a vertical support plate 111c, so that two first mounting grooves 1111 surrounded by the two support plates and the vertical support plates 111c are respectively formed on the two side edges in the width direction of the support plates; the vertical support plate 111c extends in a direction away from the center of the frame structure 110 to form a support edge 111d, and the side edge of the second support plate 111b extends in a direction away from the first support plate 111a to form a first abutment plate 111e, so that when the first abutment plate 111e faces away from the A first abutment surface 1112 is formed on one side surface of the supporting edge 111d, and the first abutment plate 111e and the supporting edge 111d have the same size in the direction away from the center of the frame structure 110; the frame profile 111 also includes a first enclosure plate 111f, the first enclosure plate 111f is parallel to the first support plate 111a, and one side of the first enclosure plate 111f is connected to the side of the first abutment plate 111e away from the first support plate 111a, and the other side of the first enclosure plate 111f extends in a direction parallel to the width direction of the first support plate 111a and away from the first abutment surface 1112, thereby forming a first enclosure surface 1113 on the side surface facing the first support plate 111a.

[0097] Specifically, the frame profile 111 formed by the first support plate 111a, the second support plate 111b, the vertical support plate 111c, and the first enclosure plate 111f is a hollow structure. The hollow structure can be formed by bending, welding, or extrusion of the plates as a whole. The manufacturing process is simple, the process and material costs are low, and the weight is easy to transport and carry; each plate body forms a plurality of separated cavities, and heating lines, electrical connection lines, insulation pads, fireproof materials and other components can be respectively arranged inside the plurality of cavities, so that the frame profile 111 and the wall panel have more functionality, and also avoid the trouble and complexity of separate wiring on the outside of the wall panel, while protecting the internal wiring; the first abutment plate 111e and the support edge 111d have the same size in the direction away from the center of the frame structure 110, and the side surface of the first abutment plate 111e facing away from the first support plate 111a and the support edge 111d can jointly provide stable support force for the entire curtain wall structure, avoiding deformation and collapse caused by long-term pressure.

[0098] Of course, the frame profile 111 is preferably configured to be structurally symmetrical on both sides in the width direction of the first support plate 111a, that is, the frame structure 110 is structurally symmetrical on both sides along the thickness direction of the hidden frame curtain wall structure, so that the wall panel units 130 on both sides of the frame structure 110 can be flexibly installed on the frame structure 110 in the same embedding manner, and the two symmetrical first abutment plates 111e and support edges 111d provide a more balanced supporting force for the entire curtain wall structure.

[0099] refer to Figure 16 In some embodiments, the difference between the distance L4 between the first enclosure surface 1113 and the first support plate 111a on the side away from the first abutting surface 1112 and the distance L3 between the first enclosure surface 1113 and the first support plate 111a on the side close to the first abutting surface 1112 is 2 mm. This is because, if there is no size difference between the first enclosure surface 1113 and the first support plate 111a, when the edge surface 133 of the wall panel unit 130 is placed on the first enclosure surface 1113, due to the presence of overflowing glue, the edge surface 133 cannot completely fit with the first enclosure surface 1113. On the one hand, the overflowing glue will seep out from the gap between the two to the surface and is difficult to clean. On the other hand, there is a gap between the edge surface 133 and the first enclosure surface 1113, which affects the appearance quality. In this embodiment, due to the 2 mm size difference, the first enclosure surface 1113 is not parallel to the first support plate 111a. When the edge surface 133 of the wall panel unit 130 is placed on the first enclosure surface 1113, a reserved gap is formed between the edge surface 133, the first enclosure surface 1113, and the first abutting surface 1112 to accommodate the adhesive. There is no gap between the portion of the first enclosure surface 1113 away from the first abutting surface 1112 and the edge surface 133, and the adhesive will not overflow. The adhesive will not be exposed to external air and water vapor in the space enclosed by the edge surface 133, the first enclosure surface 1113, and the first abutting surface 1112, thereby reducing weathering and extending the service life. At the same time, no gaps can be seen in appearance, which does not affect the appearance.

[0100] In some embodiments, the edge of the inner surface 131 of the wall panel unit 130 is adhered to the first abutment surface 1112. This adhesion ensures that the wall panel unit 130 is securely fixed, thereby ensuring that the wall panel unit 130 is firmly positioned and not easily dislodged. Furthermore, the edge of the wall panel unit 130 is provided with a mounting hole. Screws are inserted from the outside through the mounting hole and screwed into the frame structure 110, thereby securing the wall panel unit 130 to the frame structure 110. This improves the installation stability of the wall panel unit 130 and prevents it from shaking or falling off.

[0101] like Figures 17-20 In the embodiment shown, a curtain wall positioning and installation structure is provided, comprising:

[0102] A positioning track 2100 includes a positioning surface 2101 and a supporting surface 2102 disposed opposite to each other. The positioning surface 2101 is provided with first positioning protrusions 2101a on either side of the width direction. The first positioning protrusions 2101a extend along the length of the positioning track 2100 and are configured to engage with and be inserted into the transverse edge grooves 110a of the frame structure 110 of the curtain wall 10 to position the lateral edges of the curtain wall 10.

[0103] The support component 2200 is fixed to the installation surface. The support component 2200 is provided on one side of the support surface 2102 and contacts the support surface 2102 , and is used to support the positioning rail 2100 .

[0104] Specifically, when installing the curtain wall 10, the horizontal edge groove 110a at the bottom of the frame structure 110 of the curtain wall 10 is correspondingly inserted into the first positioning protrusions 2101a provided on both sides of the positioning surface 2101 of the positioning rail 2100 in the width direction, thereby using the first positioning protrusions 2101a to limit the entire structure of the curtain wall 10 in the width direction to prevent movement in the width direction; the horizontal edge groove 110a at the top of the frame structure 110 of the curtain wall 10 can also be correspondingly inserted into the first positioning protrusion 2101a of the positioning rail 2100 provided above it, thereby positioning the curtain wall 10 from both the top and bottom sides, firmly fixing the wall, and the structure is stable, and it is impossible to move or tilt in the width direction, which can ensure safe use. The support component 2200 is used to provide support for the positioning rail 2100 to ensure the stability of the positioning rail 2100 itself.

[0105] It is worth noting that the curtain wall 10 can be understood as the hidden frame curtain wall structure described above.

[0106] In some embodiments, there are two positioning rails 2100, which are arranged parallel to each other, and the positioning surfaces 2101 of the two rails are opposite to each other; the first positioning protrusions 2101a of the two positioning rails 2100 are used to respectively cooperate with the upper and lower horizontal edge grooves 110a of the inserted frame structure 110 to position the upper and lower horizontal edges of the curtain wall 10.

[0107] In this embodiment, the positioning rails 2100 arranged parallel to each other position the curtain wall 10 from the upper and lower sides, so that the wall is firmly fixed and the structure is stable.

[0108] refer to Figure 18 In some embodiments, the first positioning protrusion 2101a includes a positioning plate, and the positioning plate is perpendicular to the positioning surface 2101.

[0109] Specifically, the positioning plate used has a simple structure and can be integrally formed with the positioning rail 2100, making it easy to manufacture.

[0110] refer to Figure 18 In some embodiments, the positioning plates are provided with a thermal insulation pad 2103 or a fireproof board on the side facing away from each other. This assembly method allows the space between the positioning plates and the transverse edge groove 110a to be used to accommodate functional panels, providing the curtain wall 10 structure with thermal insulation or fireproofing properties.

[0111] refer to Figure 18 In some embodiments, the support surface 2102 is provided with third positioning protrusions 2104 on either side of the width direction. These third positioning protrusions 2104 extend along the length of the positioning rail 2100. The surfaces of the third positioning protrusions 2104 on the sides facing away from each other serve as abutment surfaces for abutting the edge of the carpet 30 inserted in the width direction between the support surface 2102 and the mounting surface. This allows the area between the support surface 2102 and the mounting surface to accommodate the edge of the carpet 30, preventing it from being exposed and enhancing its aesthetics. Furthermore, the abutment surfaces prevent the edge of the carpet 30 from extending excessively inward, ensuring a neat installation.

[0112] refer to Figure 18 In some embodiments, the adjacent surfaces of the third positioning protrusions 2104 serve as limiting surfaces for limiting the widthwise movement of the support member 2200. This arrangement ensures the robustness and structural stability of the support member 2200, thereby providing good support for the positioning rail 2100 and ensuring its stability.

[0113] refer to Figure 17 and Figure 18 In some embodiments, a height adjustment mechanism is further included on the positioning track 2100, and the height adjustment mechanism includes:

[0114] The internal threaded sleeve 2401 extends perpendicular to the positioning surface 2101 and penetrates and is fixed to the positioning rail 2100;

[0115] The external threaded rod 2402 is threadedly matched with the internal threaded sleeve 2401 and passes through the internal threaded sleeve 2401. One end of the external threaded rod 2402 passes through the supporting component 2200 and is fixed, and the external threaded rod 2402 can rotate around its own axis.

[0116] Specifically, when the height needs to be adjusted, the externally threaded rod 2402 is rotated about its own axis. Since the internally threaded sleeve 2401 is threadedly engaged with the externally threaded rod 2402, when the internally threaded rod 2402 rotates in place, the internally threaded sleeve 2401 and the positioning rail 2100 can rise or fall together due to the threaded engagement, thereby achieving the height adjustment of the positioning rail 2100. This method has a simple structure and a simple and easy-to-operate adjustment method.

[0117] refer to Figure 17 In some embodiments, the externally threaded rod 2402 has a coaxial inner hexagonal drive hole 2402a along its length. Specifically, a hexagonal wrench can be inserted into the inner hexagonal drive hole 2402a and rotated to rotate the externally threaded rod 2402, thereby achieving height adjustment. This adjustment method is simple to operate and convenient.

[0118] refer to Figure 20 In some embodiments, a vertical positioning profile 2500 is further included, which is connected to the positioning surface 2101 of the positioning rail 2100, and at least one side surface of the vertical positioning profile 2500 is provided with second positioning protrusions 2501 on both sides in the width direction. The second positioning protrusions 2501 extend along the length direction of the vertical positioning profile 2500 and are used to cooperate with the vertical edge groove 110b of the frame structure 110 inserted into the curtain wall 10 to position the vertical side of the curtain wall 10.

[0119] refer to Figure 20 In some embodiments, the two second positioning protrusions 2501 are respectively provided with a limiting protrusion 2502 on the side close to each other, and the side surface of the limiting protrusion 2502 facing the corresponding second positioning protrusion 2501 is used to block the limiting plate 110c set on one side of the vertical edge groove 110b.

[0120] In this embodiment, a limiting plate 110c is additionally provided on one side of the vertical edge groove 110b, and the limiting protrusion 2502 can block the limiting plate 110c, thereby limiting the entire curtain wall 10 in the width direction, preventing the entire curtain wall 10 from moving in the width direction, and making the structure more stable.

[0121] refer to Figure 17 In some embodiments, the vertical positioning profile 2500 is connected to the positioning track 2100 via a connecting angle piece 2600. The connecting angle piece 2600 includes a first connecting plate 2601 and a second connecting plate 2602. The angle between the first connecting plate 2601 and the second connecting plate 2602 is 90°. The connecting angle piece 2600 securely connects the vertical positioning profile 2500 to the positioning track 2100, preventing the vertical positioning profile 2500 from tilting or deforming over time. This further ensures the secure fixing structure of the curtain wall 10 and significantly improves its structural stability.

[0122] refer to Figure 18In some embodiments, the support component 2200 has a groove structure, including a base plate 2201 and support edges 2202 provided on both sides of the base plate 2201 in the width direction. The upper surfaces of the support edges 2202 are in contact with the support surface 2102. In this embodiment, the support edges 2202 provide support for the positioning track 2100, ensuring the stability of the positioning track 2100. The hollow structure is formed between the support component 2200 and the positioning track 2100 with a groove structure. The hollow structure can be installed inside the hollow structure to provide heating lines, thermal insulation pads 2103, fireproof materials, electrical connection lines, and other pipelines. This makes the structure more functional, avoids the trouble and complexity of routing individual wires outside the wall panel, and protects the wiring.
