Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a lightweight, modular exterior wall that is easy to construct. Background Technology

[0002] In building construction, exterior walls need to have functions such as waterproofing, heat insulation, and sound insulation. Traditionally, exterior walls are generally composed of structural beams, insulation layers, waterproofing layers, and interior decorative layers. The insulation and waterproofing layers are often poured using lightweight materials such as concrete and mortar.

[0003] Authorized patent CN211228991U discloses a multifunctional thermal insulation structure for building exterior walls using composite phenolic resin. This structure is composed of ceramic panels, cement mortar, and precast concrete. In reality, most existing exterior wall structures are similar in composition to those described in authorized patent CN211228991U, requiring painting of the external structural beams after assembly. Furthermore, after constructing the exterior wall frame, mortar or concrete needs to be poured into the structural beams.

[0004] Therefore, the existing exterior wall structure and its corresponding construction process have some significant drawbacks. After the exterior wall construction is completed, scaffolding needs to be erected outside the structural beams and slabs for painting or tiling, which can easily lead to safety issues. Secondly, it involves multiple processes such as masonry, pouring concrete, and plastering, requiring numerous trades and a long construction period. Furthermore, the exterior wall structural beams and slabs, assembled from multiple layers, are quite heavy, increasing the building's load. Summary of the Invention

[0005] This invention addresses the technical problems of construction safety, construction period, and large load faced by existing exterior wall structures, and provides an easy-to-construct lightweight modular exterior wall structure.

[0006] One of the concepts of this invention is to use glass as the insulation layer of the exterior wall, thereby improving the adaptability to buildings with spandrel walls.

[0007] More and more commercial buildings are now using large areas of glass for decoration, making the buildings beautiful and simple. The exterior wall structure of this invention uses glass as the insulation layer, thus integrating the exterior wall and window spandrel structure into a single design, reducing the need for structural columns in the window spandrel, and thereby improving adaptability to buildings with window spandrels.

[0008] It is worth noting that, due to the use of the glass layer, there is no need to pour mortar, insulation cotton and concrete into the exterior wall, which can greatly reduce the complexity of the exterior wall construction and save the construction period.

[0009] Furthermore, another aspect of the present invention is to use aluminum panels as exterior wall panels to achieve the goals of reducing the construction period and improving safety.

[0010] Specifically, the outer surface of the aluminum plate has a coating structure, so after assembly, there is no need to erect an external scaffold for painting the external structural beams, which improves construction safety and saves construction time.

[0011] Furthermore, thanks to the integrated design of the glass layer and the inter-wall window, the aluminum panel structure can be constructed in various styles according to the building's needs, making the exterior shape of the facade more diverse.

[0012] Based on the above concept, the present invention provides a lightweight modular exterior wall that is easy to construct, comprising: supporting columns, both ends of which are connected to structural beams; any two adjacent sets of the supporting columns and structural beams form the frame of the exterior wall;

[0013] An outer aluminum plate, a glass layer, and an interior decorative layer are sequentially arranged along the frame axis.

[0014] Based on the above technical solution, the exterior wall provided by this invention consists only of supporting columns, glass, and lightweight aluminum panels. It is lightweight, easy to assemble, and can significantly reduce the construction cycle and save production costs. Furthermore, the outer aluminum panels can be installed directly indoors, and since they are covered with a paint layer, the traditional scaffolding construction method is eliminated, saving construction time and improving construction safety.

[0015] Furthermore, it also includes a keel; the keel is disposed between the interior decoration layer and the glass layer, and is attached to the interior decoration layer.

[0016] The keel system separates the glass layer from the interior space, improving the thermal and sound insulation of the exterior wall. Simultaneously, the keel provides load-bearing support, enhancing the stability of the exterior wall structure.

[0017] Furthermore, the glass layer includes: insulated glass, used for sound insulation and heat preservation;

[0018] The glass frame includes a mounting base and a fixing buckle. One side of the mounting base is fixed to the support column, and the other side is provided with a slot that cooperates with the fixing buckle. The fixing buckle secures the insulated glass to the mounting base.

[0019] The snap-fit ​​structure solves the problem of the glass layer being difficult to install.

[0020] Furthermore, the glass frame is made of thermally insulated aluminum alloy. By using thermally insulated aluminum alloy, the heat transfer at the frame of the insulating glass is reduced, thereby improving the overall heat insulation effect of the glass layer.

[0021] In some embodiments, the insulating glass and the fixing clips are constructed as a single unit. This integrated design solves the problem of the glass being difficult to handle during installation.

[0022] In some embodiments, the outer aluminum plate is configured as a planar, right-angled, square, beveled, arc-shaped, or concave-convex shape.

[0023] It is worth noting that with the continuous development of architectural aesthetics, different styles of expression exist between buildings. However, conventional exterior wall structures, limited by load-bearing issues and the construction of the grouting layer, cannot achieve a diverse range of architectural appearances. The lightweight modular exterior wall provided by this invention abandons the traditional multi-layered grouting design, consisting only of an interior decorative layer, a glass layer, and an outer aluminum panel. Its load is only 3KN / m, and it is lightweight, requiring no additional reinforcement. Therefore, thanks to the lightweight design and simple modular structure of the exterior wall, the shape of the outer aluminum panel is not affected by the inner plane. It can be constructed into various irregular structures such as planar, right-angled, square, or beveled shapes according to actual needs, thereby meeting the requirements of different architectural appearances.

[0024] Furthermore, the outer surface of the outer aluminum plate has an inclination angle of 1°-5° compared to the inner surface.

[0025] Specifically, the outer aluminum plate is coated with paint to keep the surface clean and dust-free. However, the irregularly shaped exterior wall structure, coupled with the fact that the lightweight outer aluminum plate cannot withstand the load of a person, makes exterior wall cleaning inconvenient. Therefore, the outer surface of the outer aluminum plate of this invention has a self-cleaning angle of 1°-5° compared to the inner surface, which achieves a better self-cleaning effect without increasing assembly difficulties, thereby solving the problem of the outer aluminum plate provided by this invention being difficult to clean.

[0026] In some embodiments, the supporting columns and glass layers are used to construct a wall window.

[0027] In fact, the exterior wall structure provided by this invention, due to the combination design of glass layer and supporting columns, can be easily reused in window construction without the need to redesign the window frame structure.

[0028] It is worth noting that, since users can access the windows, the glass of the glass layer is fixedly connected to the supporting columns to improve the safety of window use.

[0029] Furthermore, the connection between the supporting column and the structural beam specifically includes: expansion bolts and fixing feet;

[0030] The expansion bolts fix the fixing feet to the structural plate beam, and the support column is sleeved on the fixing feet.

[0031] Based on the above technical solution, the use of expansion bolts and fixing feet improves the ease of assembling the support columns while ensuring the stability of the exterior wall structure.

[0032] Furthermore, the present invention also includes: a friction pad and a fixing block;

[0033] The friction pad is disposed on the joint surface of the support column and the fixed foot;

[0034] The fixing block is used to cover the bolt head of the expansion bolt.

[0035] In summary, this invention provides an easy-to-construct lightweight modular exterior wall with at least the following advantages: 1. The simple modular design ensures sound insulation and heat preservation while maintaining a load capacity of only 3KN / m. This allows it to adapt well to the edges of cantilevered components such as balconies and connecting corridors, and eliminates the need for additional reinforcement of cantilevered components in renovation projects, making it highly adaptable. 2. The overall detachable structural design allows for perfect application to the construction of windows between walls. Windows can directly reuse the supporting columns of the exterior wall, simplifying window design and installation, and reducing manufacturing and installation costs. 3. Due to the low load capacity of the exterior wall provided by this invention, the outer aluminum panel does not need to consider excessive load issues. Furthermore, benefiting from the open installation environment outside the glass layer, the outer aluminum panel can have extremely rich shapes, not limited to traditional flat wall structures, and can be constructed into various shapes according to the design requirements of the building's exterior. 4. The exterior wall provided by this invention, due to its simple modular structure, can be easily assembled indoors, reducing the types of construction work, shortening the construction period, and ensuring construction safety.

[0047] The following is in conjunction with the appendix Figures 1 to 9 The present invention will be described in detail below.

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0049] This invention provides a lightweight, modular exterior wall that is easy to construct, and has the advantages of simple installation, short construction period, low labor input, rich design and structure, safe installation, and no cleaning or maintenance required.

[0050] See Figure 1 As shown, the exterior wall provided by the present invention is constructed by supporting columns 1 on both sides and interlayer structural beams 8 on the upper and lower sides to form a basic exterior wall frame, and then an interior decorative layer 3, a glass layer 5 and an outer aluminum plate 2 are sequentially arranged from the interior to the exterior.

[0051] Specifically, after the two supporting columns 1 are assembled, the outer aluminum plate 2 can be installed, followed by the glass layer 5 and the interior decorative layer 3. Since the outer aluminum plate 2 faces outwards and can be painted, this can be done during factory manufacturing. Therefore, the exterior wall of this invention does not require additional scaffolding for construction on the outer side, thus improving construction safety.

[0052] In addition, the lightweight aluminum plate structure can be lifted by a single worker, making construction convenient and posing few safety hazards.

[0053] It is worth noting that the wall spacing between the upper and lower structural beams 8 is relatively wide. To improve the ease of construction, the exterior wall provided by this invention can be composed of multiple glass layers 5 and multiple outer aluminum plates 2. Window frames are provided between different glass layers 5, and the window frames are used to support the glass layers 5.

[0054] Meanwhile, the interlayer of the exterior wall provided by this invention does not require the pouring of other materials, which can greatly reduce the input of various construction trades and thus shorten the construction cycle.

[0055] In fact, to ensure the sound insulation and heat preservation effect of the exterior wall, the present invention adopts a double-glazed or laminated glass design, thereby constructing an air layer structure between the interior decorative layer 3 and the outer aluminum plate 2, to obtain better sound insulation and heat preservation effect, as well as enhance the moisture-proof performance of the structural beam 8.

[0056] Further, see Figure 1 As shown, a keel 4 is also provided between the interior decorative layer 3 and the glass layer 5. The keel 4 makes the interior decorative layer 3 smoother during construction. At the same time, it can also reinforce the interior decorative layer 3 and prevent it from being damaged during long-term use.

[0057] Further, see Figure 2 As shown, Figure 2 This is a perspective diagram illustrating the construction process. After the supporting column 1 is installed, the window frame of the glass layer 5 can be installed indoors, followed by the installation of the outer aluminum plate 2, then the insulated glass, and finally the interior decorative layer, thus completing the installation of the entire lightweight modular exterior wall. The installation process provided by this invention is simple, can be completed indoors, has a short construction period, and is quick and easy to install.

[0058] Further, see Figure 7 As shown, the glass layer 5 includes insulated glass and a glass frame. The glass frame includes a fixing seat 12 and a fixing buckle 11. The fixing seat 12 is fixed to the support column 1 by means of threaded connection. The insulated glass is placed in the slot of the fixing seat 12, and then the insulated glass is fixed by the fixing buckle 11.

[0059] Furthermore, the fixing buckle 11 is positioned in the indoor direction and includes two retractable buckle heads, which are received in the buckle groove of the fixing seat 12 under the action of thrust, thereby fixing the middle layer of glass.

[0060] Specifically, during construction, workers can easily install glass layer 5 using a snap-fit ​​structure, thereby reducing construction complexity and saving construction time.

[0061] Furthermore, the fixing buckle 11 can be integrated with the insulating glass to facilitate the handling of the insulating glass and prevent damage during transportation.

[0062] Specifically, the edges of the insulated glass unit are secured with clips to form a single, integrated component, facilitating transportation and preventing damage or scratches. Furthermore, a wedge-shaped interface is incorporated between the clips and the mounting base to increase friction and ensure a more secure installation.

[0063] Furthermore, the glass frame is made of thermally broken aluminum alloy, so that the glass layer 5 is constructed as a whole as a heat-insulating and sound-insulating structure, which makes the sound insulation and heat preservation effect of the exterior wall provided by the present invention better.

[0064] In some embodiments, see Figure 1 As shown, the outer aluminum plate 2 is constructed in a conventional planar shape; see Figure 4 As shown in Figure 2a, the outer aluminum plate 2 is constructed in a right-angled shape; see Figure 5 As shown in Figure 2b, the outer aluminum plate 2 is constructed in a beveled shape; see Figure 6 As shown in 2c, the outer aluminum plate 2 is constructed in a square shape.

[0065] In fact, since the interior decorative layer 3 and the glass layer 5 have already achieved the sound insulation and heat insulation effects of the exterior wall, the outer aluminum panel 2 does not need to bear the function of the exterior wall. Therefore, the open end of the glass layer 5 facing the outside can be constructed into various shapes, such as arcs, concave and convex shapes, etc., which will not be illustrated here. Basically, any shape of the outer aluminum panel that can be set outside the glass layer can be realized, thus adapting to buildings with styling requirements for the exterior wall.

[0066] Furthermore, for the outer aluminum plate 2 that can be connected to the glass layer 5, it is fixed by the frame of the glass layer 5 and the structural beam 8; for the outer aluminum plate 2 that is not directly connected to the glass layer 5, it can be directly fixed between the upper and lower structural beams 8.

[0067] Furthermore, the outer surface of the outer aluminum plate 2 is inclined at an angle of 1°-5° compared to the inner surface.

[0068] Although the outer aluminum plate 2 has a painted coating that provides some dust protection, its irregular shape and relatively weak load-bearing capacity prevent manual cleaning of the outer surface. The angled design of the outer surface allows the outer aluminum plate 2 to be clean-free and maintenance-free.

[0069] Further, see Figure 3 As shown, a wall window can be constructed using only the supporting column 1 and the glass layer 5.

[0070] Specifically, the windows can be integrated with the exterior wall provided by this invention and the supporting column 1 can be reused, thereby reducing design and manufacturing costs as well as construction costs.

[0071] In fact, to meet the needs of window opening and closing and safety, a snap-on installation structure can be omitted, and a conventional window structure design can be used for window installation.

[0072] In some embodiments, see Figure 8 As shown, the support column 1 is installed by snapping it onto the fixed foot 7, and the fixed foot 7 is fixed to the structural beam 8 by expansion bolts 9.

[0073] Through the structural design of the connection method of the support column 1, the support column 1 provided by the present invention can be installed quickly and has a good fixing effect.

[0074] Furthermore, a friction pad 10 is provided between the supporting column 1 and the fixed foot 7 to improve the tightness of the connection between the two. The bolt head of the expansion bolt 9 is fixed by the fixing block 6.

[0075] Furthermore, the fixing block 6 is prepared by casting.

[0076] In some embodiments, see Figure 9 As shown, the corners of the exterior walls are connected by support columns 1 at a certain angle.

[0077] In fact, the exterior wall provided by this invention can form an arc-shaped corner by setting multiple sets of angled supporting columns 1 at the corner, making the building shape more diverse.

[0078] The present invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the invention. The descriptions of the embodiments above are only for the purpose of helping to understand the invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
