[0032] Modular design: It consists of two parts: a panel including glass, metal, and stone, and a supporting structure including columns and beams. Sometimes decorative lines are also used as edge finishing and shape reinforcement components.
[0033] Decorative moldings function to cover seams and create spatial layers. Materials include stone, stainless steel, and PVC, and they support customized shapes such as L-shaped and U-shaped. The supporting structure of decorative molding curtain walls typically includes two types: component-type (with on-site installed columns and beams) and unit-type (prefabricated in the factory). The main materials for decorative molding curtain walls are diverse, including glass curtain walls, stone curtain walls, aluminum panels, stainless steel, and other metal panel curtain walls. The main decorative forms of decorative molding curtain walls also include exposed frame structures, partially concealed semi-concealed frame structures, and fully concealed frame structures. In addition, there are some special technologies involving double-layer dynamic curtain walls, photovoltaic curtain walls, and cable-net point-supported curtain walls.
[0034] This utility model includes: a strip 2, a back panel 3, countersunk rivets 4, and an aluminum bar 5; a group of horizontally placed strips 2 are installed parallel to each other on the front side of the vertically set back panel 3; an aluminum bar 5 is placed between the strip 2 and the back panel 3; the countersunk rivets 4 pass through the strip 2, the aluminum bar 5, and are riveted to the back panel 3 to form a small unit decorative strip curtain wall.
[0035] This invention optimizes the installation structure of small-unit decorative line curtain wall components, employing customized small-unit decorative lines whose shape and size are designed according to the actual needs of the building facade. The decorative lines are made of materials with good weather resistance and strength to ensure they are not easily deformed or damaged during long-term use. This ensures the integrity and aesthetics of the curtain wall appearance, reducing visual interference. The installation technology is optimized to ensure high-precision alignment of the line seams. If seams exist, they must be aligned with high precision to the point of being invisible to the naked eye, thereby enhancing the sophistication of the curtain wall.
[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0037] Example 1: A partial curtain wall with multiple small decorative units sandwiched between two exterior windows on the upper and lower floors of a building facade, as shown in the attached diagram. Figure 1 As shown, the curtain wall features multiple sets of small decorative line units arranged horizontally at the bottom of the exterior window 1.
[0038] As mentioned above, as attached Figure 2As shown, each small unit of decorative line curtain wall is prefabricated with multiple aluminum square tube lines 2 with horizontal metal line effect. Specifically, line 2 is an aluminum square tube with a hole in the rear side wall of the aluminum square tube. A group of horizontally parallel and evenly spaced lines 2 are riveted and fixed to the front side of the back panel 3 by passing countersunk rivets 4 through the hole in the rear side wall of the aluminum square tube.
[0039] As mentioned above, as attached Figure 3 As shown, before the installation of the small unit decorative line curtain wall, an external backing board 10 is attached to the exterior wall surface of the mezzanine between the upper and lower two-story exterior windows, and keels 6 are erected and fixed at intervals on the surface of the external backing board 10.
[0040] In this embodiment of the utility model, after the mounting line 2 is riveted and fixed to the front side of the back plate 3, it is then fixedly installed on the front side of the keel 6.
[0041] In particular, countersunk rivets 4 are inserted through holes in the rear side wall of aluminum square tube 2, and vertically padded with aluminum strips 5 corresponding to the holes, which are then riveted and fixed to the front side of back plate 3. (See attached image) Figure 4 , 5 As shown, the aluminum bar 5 has spaced holes, and the inner wall of the hole is a conical slope.
[0042] In this embodiment of the utility model, aluminum bar 5 is used as a connection node for linear curtain wall structure, especially in aluminum panel curtain wall, the cross section node design shows the connection method between linear bar 2, back panel 3 and supporting structure.
[0043] In particular, to strengthen the connection between the aluminum bar 5 and the back plate 3, the aluminum bar 5 and the back plate 3 are riveted and fixed by countersunk rivets 4 between two adjacent upper and lower lines 2, and rivet caps 7 are sleeved on the end of the riveting point on the surface of the aluminum bar 5.
[0044] Preferably, the window opening width of exterior window 1 is <12000mm. Line 2 is a 30*20*1.5mm fluorocarbon-coated aluminum square tube. Line 2 and aluminum busbar 5 are processed and assembled in the factory. Depending on the manufacturer's production capacity, the longest aluminum alloy square tube for line 2 can be 6750mm. In small curtain wall units, line 2 has no gaps or at most one seam. Back panel 3 is a 2.5mm thick fluorocarbon-coated aluminum single-panel panel or a 10*380*3mm aluminum plate. Countersunk rivets 4 are K4 stainless steel countersunk rivets. Aluminum busbar 5 is a 3mm thick fluorocarbon-coated aluminum busbar. Keel 6 is a 60*60*2.5mm fluorocarbon-coated aluminum square tube. After staggering the butt joint of adjacent back panels 3, line 2 and back panel 3 are connected by aluminum busbar 5 and K4 countersunk rivets 4 are driven on-site. The rivets are pulled into the aluminum plate, with a rivet thickness of 4.5mm. Furthermore, a rivet cap 7 is placed on the rivet head of the countersunk rivet 4.
[0045] In this embodiment of the invention, 30201.5 fluorocarbon-coated aluminum square tubing is used to further optimize the stability of the structure and provide reliable support for the decorative lines. 3mm thick fluorocarbon-coated aluminum bars are used as connecting components, with a bar length ≤1250mm. Through reasonable layout and connection, the connection strength between the decorative lines and the main curtain wall structure is enhanced.

In areas without adhesive seams, the rivets are pulled into the aluminum plate, and the rivet heads are capped with adhesive, ensuring both connection stability and improved surface smoothness.
[0046] The implementation principle of this embodiment is as follows: During installation, positioning and fixing are strictly carried out according to design requirements. First, the installation position of decorative line 2 is determined, and then professional installation tools are used to fix decorative line 2 to the curtain wall body using countersunk rivets 4 and aluminum brackets 5, etc. During installation, attention should be paid to controlling the installation accuracy to ensure that the horizontality and verticality of the decorative line meet the design standards. The installation process is as follows:
[0047] 1) The aluminum square tube 2 is fixed to a set of vertically installed aluminum bars 5 by a countersunk rivet 4 through the opening in the back wall.
[0048] 2) After the horizontally placed multiple lines 2 and the vertically placed multiple aluminum bars 5 are assembled into a line unit, the line unit is then installed on the wall and fixed to the outer wall 9 and the outer lining plate 10 by the aluminum bars 5.
[0049] 3) Use stainless steel pan head rivets to install the line unit onto the aluminum panel of the back panel 3;
[0050] 4) The two linear units are fixed to the aluminum panel of the back panel 3 by their respective aluminum brackets 5 at the seam.
[0051] 5) The line unit, as well as the line unit and the back panel 3 aluminum panel unit are assembled in the processing plant, which can achieve high precision at low cost;
[0052] 6) The seam between the two linear units is set to "0mm", with an installation accuracy of 0.1mm, so that the seam is invisible to the naked eye.
[0053] In this embodiment of the invention, the unitized curtain wall components are prefabricated in the factory, improving on-site installation efficiency by 30%-50% and facilitating construction. The exposed structure is easy to inspect and maintain, and the modular design supports partial replacement, making maintenance convenient.
[0054] Example 2: As shown in the attached document Figure 6As shown, in general, expansion bolt sleeves are installed on the partial wall pad 17 on the surface of the exterior wall 9 at the lower edge of the exterior window 1, and then the outer lining plate 10 is fixedly installed on the surface of the exterior wall 9 with screws 16; furthermore, the keel 6 is vertically fixedly installed on the front side of the outer lining plate 10 by the connector 13 embedded in the exterior window 1; the back plate 3 and the line 2 are installed on the outside of the keel 6; in particular, the back plate 3 and the line 2 are fixed at the upper and lower ends of the keel 6 by the butt brackets 8 respectively.
[0055] As mentioned above, as attached Figure 7 As shown, after the two adjacent aluminum square tubes are aligned at their joint nodes, holes are opened in the rear wall of the ends, and aluminum bars 5 are riveted and fixed to the back plate 3 by countersunk rivets 4.
[0056] As described above, two adjacent back panels 3 are joined together and fixed to the front side of the keel 6 by the rear joining support 8. (See attached diagram) Figure 8 , 9 As shown, the docking support 8 has a groove structure, and the bottom of the groove of the docking support 8 is fixed to the front wall of the keel 6 by the screw 16; clamping bolts are installed in corresponding holes on the two opposite walls of the groove of the docking support 8; specifically, the edges of the two adjacent back plates 3 are folded backward and inserted into the groove of the front side of the docking support 8. The caulking strip 14 and the vibration damping support pad 15 are inserted between the folded edges of the two adjacent back plates 3 inserted into the groove of the front side of the docking support 8, and then fastened by the clamping bolts.
[0057] As mentioned above, as attached Figure 10 As shown, exterior finishes 12 are installed on the upper and lower ends of the keel 6, back panel 3, and line 2 respectively; specifically, an angle steel structure edge pad 19 is pressed onto the top of the keel 6, and an angle steel structure connecting seat 11 is pressed onto the top of the inner root of the outer lining plate 10 and the top surface of the edge pad 19. The connecting seat 11 presses the inner edge of the exterior finish 12 onto the bottom support structure of the outer window 1 with screws; at the same time, the lower outer edge of the exterior finish 12 is pressed onto the top outer edge of the back panel 3.
[0058] Preferably, square aluminum alloy profiles are used as the molding 2, fully utilizing the advantages of aluminum alloy such as light weight, high strength, and corrosion resistance. The aluminum alloy molding 2 can be made up to 6750mm in length, depending on the manufacturer's production capacity. When the window opening width of the exterior window 1 is less than 12000mm, the joints of molding 2 should be as seamless or have as few seams as possible. Molding 2 can meet the requirements with just one seam or no seam at all. If there are seams in the joints of molding 2, they need to be precisely aligned and invisible to the naked eye. Multiple moldings are assembled in a modular fashion before being installed on the wall. This modular assembly is completed in the processing plant, enabling high-precision cost control, improving production efficiency, and reducing on-site construction difficulty.
[0059] In this embodiment of the utility model, this small-unit curtain wall structure with metal decorative lines effectively solves problems such as line splicing and installation accuracy by optimizing the installation structure, installation method and connection nodes, combined with material selection, thereby improving the overall quality and appearance of the curtain wall. It has high practical value and promotion significance.
[0060] In this embodiment of the utility model, the aluminum square tube line 2 and the aluminum bar 5 are connected by a K4 countersunk rivet 4 with a rivet thickness of 4.5mm to ensure the reliability of the connection.
[0061] Preferably, the back panel 3 uses a lightweight new type of board material, with a thickness as thin as 1mm, such as hyperbolic aluminum plate, which reduces weight by more than 50% compared to traditional stone. Furthermore, the back panel 3 uses PVC decorative lines with a layered design, integrating a decorative layer, a corrosion-resistant layer, and a waterproof layer, making it an impact-resistant, weather-resistant, and multifunctional composite material. Furthermore, the back panel 3 uses Low-E glass, metal insulation boards, and other materials to improve thermal insulation performance, meeting green building standards for environmental protection and energy conservation.
[0062] Preferably, by optimizing the visual effect of the aluminum square tube lines, a horizontally exposed and vertically concealed glass curtain wall is simulated. The exposed horizontal beams bear the load, while the concealed vertical beams enhance the overall structural integrity. Through reasonable node design and connection methods, the final result is a smooth, aesthetically pleasing curtain wall facade with flowing lines, meeting the architectural design requirements.
