Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel curtain wall technology, specifically a perforated aluminum single-panel curtain wall. Background Technology

[0002] Aluminum single-panel is a new type of building decoration material made of aluminum alloy sheet as the base material, which is processed by cutting, bending, stamping and surface treatment (such as spraying, fluorocarbon coating, etc.). It has the characteristics of light weight, high strength, corrosion resistance and strong decoration. Curtain wall is the enclosure structure of the exterior wall of a building. It does not bear the load of the main structure and mainly plays the roles of decoration, heat preservation, sound insulation and lighting. Aluminum single-panel curtain wall is a type of curtain wall with aluminum single panel as the core decoration and enclosure unit. With its advantages of flexible shape and rich color, it has become a common choice for modern building facade design.

[0003] Currently, aluminum single-panel curtain walls still have significant drawbacks in practical applications: Firstly, most existing aluminum single panels adopt a straight-edge structure, requiring the connection to the curtain wall frame to be achieved by welding or bolting corner brackets on the sides. The installation of corner brackets can easily lead to spatial interference when splicing adjacent aluminum single panels. To avoid the corner brackets, the spacing between panels needs to be increased, forming obvious gaps, which affects the aesthetics of the curtain wall and is also prone to rainwater seepage and dust accumulation. Secondly, fixing the corner brackets requires directly drilling bolt holes on the side of the aluminum single panel. These holes will damage the structural integrity of the side of the aluminum single panel, leading to local stress concentration and reducing the deformation resistance and load-bearing strength of the aluminum single panel edge. Especially in large-size aluminum single panels or in scenarios subject to long-term wind pressure, safety hazards such as side bending and cracking are likely to occur. Utility Model Content

[0004] The purpose of this utility model is to provide a perforated aluminum panel for curtain walls to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A perforated aluminum panel for curtain walls, comprising:

[0007] The aluminum single panel is frame-shaped, and the bottom edge of the frame has an inwardly folded edge. The inwardly folded edge is integrally formed with the aluminum single panel and is parallel to the top surface of the aluminum single panel, so as not to affect the installation of the aluminum single panel.

[0008] The inner side of the inner flange is fixedly connected with reinforcing ribs and mounting components. The setting of reinforcing ribs and mounting components does not affect the overall installation and appearance of the aluminum panel. The reinforcing ribs are used to improve the structural strength of the aluminum panel, and the mounting components are used to connect and fix the aluminum panel to the external curtain wall frame.

[0009] Preferably, the reinforcing rib comprises a connecting plate, and the connecting plate is L-shaped. One end face of the connecting plate is closely attached to the inner side of the inward flange, and a first threaded hole is provided on this attached end face. A matching through hole is provided at a position on the inward flange corresponding to the first threaded hole. A first flat-head screw penetrates into the through hole from the outer side of the inward flange and is threadedly connected with the first threaded hole, so as to firmly fix the reinforcing rib on the inner side of the inward flange. In addition, the head of the first flat-head screw completely fits the outer surface of the inward flange and does not protrude from the outer side of the inward flange, so as to avoid affecting the overall installation and appearance flatness of the aluminum veneer.

[0010] Preferably, the reinforcing rib is in a cross-shaped structure, comprising a transverse rib and a longitudinal rib that are vertically crossed. The connection between the transverse rib and the longitudinal rib is fixed by a full welding process to ensure the connection strength of the ribs. The end points of the reinforcing rib are respectively welded and fixed to the end faces of the L-shaped connecting plates at corresponding positions, so as to ensure the connection stability between the reinforcing rib and the connecting plates, and avoid affecting the use of the internal space of the aluminum veneer or the installation operation due to welding protrusions.

[0011] Preferably, a through mounting hole is provided in the middle of the front end face of the mounting member, and the mounting hole is used for a bolt to pass through and connect with an external curtain wall frame, so as to realize the overall mounting and fixing of the aluminum veneer, and the rear end face of the mounting member is fixedly connected with the bending portion.

[0012] Preferably, the bending portion is in a box-opening-shaped structure, one vertical side is attached to the outer side wall of the inward flange, and the top end of the other vertical side is folded inward and attached to the inner side wall of the inward flange, so that the bending portion and the inward flange form a wrapped fit. A correspondingly positioned second threaded hole is provided on each of the vertical sides on both sides of the bending portion, a through through hole is provided on the inward flange at a position corresponding to the second threaded hole, and a second flat-head screw penetrates into the through hole from the outer side of the inward flange and is threadedly connected with the second threaded holes on the vertical sides on both sides of the bending portion, so as to firmly fix the mounting member on the inward flange. In addition, the head of the second flat-head screw completely fits the outer side surface of the bending portion, so as to avoid affecting the installation and appearance flatness of the aluminum veneer.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The present utility model, by providing the inward flanges integrally stamped and formed with the aluminum veneer, replaces the straight-edge structure of the aluminum veneer in the prior art. It can realize the fixation of the reinforcing rib and the mounting member without drilling holes on the side edge of the aluminum veneer, avoid damaging the structural integrity of the aluminum veneer, and can enhance the anti-deformation capability of the edge of the aluminum veneer through the flange design, which solves the problem of reduced strength of the aluminum veneer caused by drilling in the prior art.

[0015] The utility model improves the overall structural strength of the aluminum veneer in all directions by arranging a reinforcing rib composed of an "L"-shaped connecting plate and a "cross"-shaped rib, combining the fixing mode of full welding at the intersection of the "cross"-shaped rib and welding of the four ends to the connecting plate, as well as the screw connection structure between the connecting plate and the inward flanging, can effectively prevent the aluminum veneer from deforming under external force or self-weight. Meanwhile, the installation mode of obliquely placing the aluminum veneer gives consideration to the convenience of assembly, and avoids the influence of a protruding structure on the use of internal space.

[0016] The utility model, by arranging a mounting member with a "匚"-shaped bending part, utilizes the wrapping fit of the bending part on the centering flanging, and cooperates with the connection mode of the threaded hole II and the flat head screw II, can not only ensure the firm fixation of the mounting member and the inward flanging, but also avoid the influence of protruding screws on the installation accuracy and appearance flatness of the aluminum veneer, ensure the stability of the connection between the aluminum veneer and the curtain wall frame, prevent shaking and deviation during use, and the mounting members between adjacent aluminum veneers do not interfere with each other, ensuring that the curtain wall surface is flat and the gaps are uniform.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figures 2 to 7 This utility model provides a technical solution:

[0028] A perforated aluminum panel for curtain walls includes an aluminum panel 1, reinforcing ribs 3, and mounting components 4.

[0029] The aluminum panel 1 has a frame structure. The four edges of the bottom of the frame are folded inward to form an inner flange 2. The inner flange 2 and the aluminum panel 1 are processed by an integral stamping process to ensure the structural stability of the connection between the two. The top surface of the inner flange 2 is parallel to the top surface of the aluminum panel 1. At the same time, the middle of the frame of the aluminum panel 1 is a hollow area, which can effectively reduce the overall weight of the aluminum panel 1 and reduce the load-bearing pressure of the external curtain wall frame.

[0030] It should be noted that the width of the inner flange 2 is preferably between 20mm and 40mm, and its thickness is consistent with that of the aluminum panel 1. This avoids affecting the installation of subsequent components due to dimensional deviations, and also enhances the deformation resistance of the aluminum panel 1's edges through the flange structure. The surface of the aluminum panel 1 is also uniformly perforated with several holes. The perforations can be designed in regular shapes such as circles, squares, or rhombuses, which can meet the lighting and ventilation requirements of the curtain wall and enhance the decorative effect of the building facade.

[0031] The reinforcing rib 3 is used to improve the overall structural strength of the aluminum panel 1 and prevent the aluminum panel 1 from deforming due to external forces or its own weight during installation and use. It consists of two parts: an "L"-shaped connecting plate 301 and a "+"-shaped rib.

[0032] The connecting plate 301 is L-shaped, with one end face designed as a mating surface that fits tightly against the inner wall of the inner flange 2. A threaded hole I302 is provided on the mating surface (the hole diameter is set according to the installation requirements, usually 4mm to 8mm). A matching through hole is provided on the inner flange 2 at the position corresponding to the threaded hole I302. The diameter of the through hole is slightly larger than the diameter of the threaded hole I302, so that the flat-head screw I303 can be inserted.

[0033] The overall rib body of the reinforcing rib 3 is in a cross shape, which is composed of mutually perpendicular transverse rib bodies and longitudinal rib bodies. The intersection of the transverse rib bodies and the longitudinal rib bodies is fixed by a full welding process, and the weld is polished after welding to ensure a flat surface of the rib body and avoid stress concentration. The four ends of the cross-shaped rib body are all closely fitted to the non-fitting end faces of the L-shaped connecting plates 301 at corresponding positions, and the top ends and the connecting plates 301 are also fixed by welding. After welding is completed, the welded parts are smoothed to prevent the raised structures from affecting the use of the internal space of the aluminum veneer 1 or the installation operation.

[0034] In this embodiment, when installing the reinforcing rib 3, the assembled cross-shaped rib body and the L-shaped connecting plate 301 assembly are tilted first, so that one end of the rib body extends from the edge of the hollow area of the frame-shaped structure of the aluminum veneer 1, and the angle is slowly adjusted until the fitting surface of the L-shaped connecting plate 301 is aligned with the inner side wall of the inward flanging 2. Then the other end of the rib body is smoothly placed into the hollow area to ensure that the fitting surfaces of the four L-shaped connecting plates 301 are all closely fitted to the inner side walls of the inward flanging 2 at corresponding positions. The flat head screw I 303 penetrates into the through hole from the outer side of the inward flanging 2, and then threadedly engages with the threaded hole I 302 on the fitting surface of the L-shaped connecting plate 301 until the head of the flat head screw I 303 completely fits the outer surface of the inward flanging 2 and does not protrude from the inward flanging 2. This not only ensures the firm connection between the reinforcing rib 3 assembly and the inward flanging 2, but also prevents the protruding screw from affecting the installation accuracy and appearance flatness of the aluminum veneer 1.

[0035] The mounting member 4 is used to realize the connection and fixation between the aluminum veneer 1 and an external curtain wall frame. The mounting member 4 is of a rectangular flat plate structure, and a through mounting hole 401 is opened in the middle of its front end face (the hole diameter is set according to the connection requirements of the curtain wall frame, and is usually 8mm to 12mm). The inner wall of the mounting hole 401 is chamfered to facilitate the penetration of connecting bolts; during installation, the connecting bolts pass through the mounting hole 401 and are threadedly connected with a preset connecting piece on the external curtain wall frame, so as to realize the overall installation and fixation of the aluminum veneer 1.

[0036] The bent portion 402 is fixed at the rear end of the mounting member 4 and is generally in a U-shape (as Figure 6 shown), the vertical edges on both sides of the bent portion are respectively adapted to the outer side wall and the inner side wall of the inward flanging 2. One vertical edge is closely fitted to the outer side wall of the inward flanging 2, and the top end of the other vertical edge is folded inward toward the inside of the aluminum veneer 1 and closely fitted to the inner side wall of the inward flanging 2, forming a wrapping fitting structure for the middle flanging (as Figure 4 shown), which improves the connection stability between the mounting member 4 assembly and the inward flanging 2. Corresponding threaded holes II 403 are opened on the vertical edges on both sides of the bent portion 402, the thread specification is the same as that of the threaded hole I 302 to ensure installation universality. A through hole is opened at the position on the inward flanging 2 corresponding to the threaded hole II 403, the diameter of the through hole is slightly larger than the aperture of the threaded hole II 403, which facilitates the penetration of the flat head screw II 404.

[0037] In this embodiment, when using the mounting component 4, the flat-head screw II 404 is inserted into the pre-set through hole from the outside of the inner flange 2, and then screwed into the threaded holes II 403 on both sides of the vertical edge of the bent portion 402 until the head of the flat-head screw II 404 is completely in contact with the outer side of the bent portion 402 and does not protrude from the bent portion 402. This ensures a firm connection between the mounting component 4 and the inner flange 2, and also avoids the screw protruding from affecting the installation and appearance flatness of the aluminum panel 1. In addition, the mounting component 4 is distributed at intervals along the inner flange 2 of the aluminum panel 1. Typically, each aluminum panel 1 is provided with at least 4 sets of mounting component 4 (located near the four corners of the aluminum panel 1 frame), ensuring a stable connection between the aluminum panel 1 and the curtain wall frame and preventing the aluminum panel 1 from shaking or shifting during use.

[0038] In existing related technologies, such as Figure 1 As shown, although the aluminum single panel 1 for the curtain wall also adopts a frame structure, its bottom edge of the frame does not have an inner flange 2, but remains a straight edge a without folding. In order to achieve the connection between the aluminum single panel 1 and the external curtain wall frame, the existing technology usually uses an independent corner bracket b as a connector. The corner bracket b is in the shape of an "L" and one side is fixed to the outer wall of the straight edge a by welding or bolting, while the other side is used to connect with the external curtain wall frame. When two adjacent aluminum panels 1 are installed side by side, the corner brackets b of the two aluminum panels 1 are prone to spatial interference in the splicing area. If the spacing between adjacent panels is increased to avoid the corner brackets b, it will result in obvious gaps between the aluminum panels 1. This will not only affect the sealing and aesthetics of the overall appearance of the curtain wall, but may also cause rainwater to seep in and dust to accumulate due to the large gaps. Fixing the corner brackets b requires bolt holes to be directly drilled on the straight edge a side of the aluminum panel 1. These holes will damage the overall structural integrity of the side of the aluminum panel 1, causing local stress concentration on the straight edge a, reducing the deformation resistance and load-bearing strength of the edge of the aluminum panel 1.

[0039] like Figure 7As shown, when two adjacent aluminum panels 1 are installed side by side on the curtain wall, due to the structural design characteristics of the mounting component 4, a tight connection and interference-free assembly of the two aluminum panels 1 can be achieved. Specifically, the "U"-shaped bend 402 of the mounting component 4 only forms a wrapping fit with the inner flange 2 of a single aluminum panel 1, and the entire mounting component 4 assembly (including the mounting plate and the bend 402) is located outside the inner flange 2 of the corresponding aluminum panel 1, and does not extend to the outside of the side of the aluminum panel 1. The mounting components 4 of the two aluminum panels 1 are each independently fixed to their own inner flange 2, without overlapping or obstructing each other. Meanwhile, a fine-tuning gap of 3mm to 5mm can be reserved at the joint between two adjacent aluminum panels 1. This facilitates precise calibration of the position of the aluminum panel 1 during installation and ensures that the surfaces of the two aluminum panels 1 are flush after being placed side by side. This avoids splicing protrusions or uneven gaps caused by interference from the mounting component 4. Furthermore, the independent fixing method of the mounting component 4 ensures that each aluminum panel 1 can form a firm connection with the external curtain wall frame, avoiding stress concentration caused by mutual restraint between adjacent panels.

[0040] In use, this utility model first determines the installation position of each aluminum panel 1 according to the curtain wall installation plan, and transports the aluminum panel 1 to the corresponding installation area; then, the aluminum panel 1 is lifted so that the mounting hole 401 at the front end of the mounting component 4 is aligned with the preset connection hole on the external curtain wall frame, the connecting bolt is inserted and tightened to initially fix the position of the aluminum panel 1; then, the horizontal and verticality of the aluminum panel 1 are adjusted to ensure that the surfaces of adjacent aluminum panels 1 are flush, and after calibration, the connecting bolt is tightened again to complete the installation of a single aluminum panel 1. When installing subsequent aluminum panels 1, there is no need to disassemble the already installed panels. The mounting component 4 of the aluminum panel 1 to be installed is directly inserted into the gap at the bottom of the adjacent already installed aluminum panel 1, so that the mounting hole 401 at the front end of the mounting component 4 is aligned with the preset connection hole at the corresponding position on the curtain wall frame; the connecting bolt is inserted from the back side of the curtain wall frame and initially tightened. After adjusting the horizontal and verticality of the aluminum panel 1 to be installed and calibrating it correctly, the connecting bolt is tightened again from the back side of the curtain wall to complete the installation of the aluminum panel 1. Install all aluminum panels 1 in sequence according to this process until the entire curtain wall assembly is completed.

[0041] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
