Description

Technical Field

[0001] This application relates to the technical field of exterior wall protection structures, and in particular to a prefabricated exterior wall structure. Background Technology

[0002] In the field of building construction, exterior wall protection structures are crucial for ensuring the safety, durability, and energy efficiency of buildings. With the promotion of prefabricated building technology, traditional exterior wall construction techniques, due to their large on-site workload, long construction cycles, and the disconnect between insulation and protective performance, are no longer sufficient to meet the demands of modern buildings for high efficiency, greenness, and multifunctionality. As the construction industry continues to develop, prefabricated buildings are increasingly favored due to their advantages such as fast construction speed and controllable quality. In prefabricated buildings, the exterior wall protection structure plays a vital role in the building's safety, durability, and aesthetics.

[0003] However, traditional exterior wall protection structures use L-shaped brackets to fix the protective panels to the wall. The brackets are connected to the wall only by a single expansion bolt, which is insufficient for wind load resistance. At the same time, there is no effective connection between the protective panels in the traditional process. When a panel is under stress, the load cannot be transferred to the adjacent components, which can easily lead to a chain reaction of falling off and pose a safety hazard. Utility Model Content

[0004] In order to reduce the safety hazards caused by the poor overall integrity of traditional protective components, this application provides a prefabricated exterior wall structure.

[0005] This application provides a prefabricated exterior wall structure using the following technical solution:

[0006] A prefabricated exterior wall structure includes a main wall. Several sets of wall frames are evenly arranged on the outer side of the main wall. The wall frames are arranged parallel to each other and are fixedly connected to the main wall. An auxiliary bracket is also installed between adjacent wall frames. The two sides of the auxiliary bracket are fixed to the wall frame. Several positioning slots are arranged from top to bottom on the outer side of the wall frame. Positioning seats are inserted into the positioning slots and are engaged and fixed to the wall frame. A protective plate is also installed on the outer side of the wall frame. The two ends of the protective plate are fixedly connected to the positioning seats.

[0007] By adopting the above technical solution, wall frames are installed on the main wall. These wall frames are parallel to each other and fixedly connected to the main wall, ensuring the stability of the basic framework of the entire external wall protection structure. The wall frames are fixed to the main wall using bolts and other mechanisms, facilitating the hanging and installation of protective panels. Auxiliary brackets are installed between adjacent wall frames, further enhancing the structural stability and ensuring that several wall frames can form a unified structure. The auxiliary brackets and wall frames can be fixed by welding. The positioning slots and positioning seats on the wall frames make the installation of protective panels more convenient, enabling quick and accurate positioning and fixing of the protective panels, thus improving construction efficiency. At the same time, the protective panels protect the external wall, preventing external factors from eroding the main wall and extending its service life.

[0008] Optionally, the wall frame includes a main frame plate and side ear seats, the side ear seats being symmetrically installed on both sides of the main frame plate, and the side ear seats being integrally formed with the main frame plate.

[0009] By adopting the above technical solution, the wall-mounted frame uses a one-piece structure of main frame plate and side lugs. This design not only enhances the structural strength of the wall-mounted frame itself, but also facilitates the fixed installation of the wall-mounted frame to the main wall, improving the stability and firmness of the installation. The one-piece molding process also reduces assembly steps in the production process, lowering production costs.

[0010] Optionally, two sets of positioning strips are symmetrically installed in the positioning slot, and the positioning strips are integrally formed with the main frame plate.

[0011] By adopting the above technical solution, the positioning strips symmetrically installed in the positioning slot are integrally formed with the main frame plate. The positioning strips can play a precise positioning and guiding role for the positioning seat, ensuring that the positioning seat can be accurately inserted into the positioning slot and can be tightly locked after insertion, preventing the positioning seat from shaking or shifting, thereby ensuring the stability of the protective plate installation.

[0012] Optionally, the positioning seat includes an I-beam base and an auxiliary support plate. The I-beam base is inserted into the positioning slot, and the auxiliary support plate is horizontally disposed on the outer side of the I-beam base. The auxiliary support plate is integrally formed with the I-beam base, and the two ends of the auxiliary support plate are provided with connecting through holes.

[0013] By adopting the above technical solution, the I-beam design of the positioning seat allows it to be tightly inserted into the positioning slot, achieving a secure engagement with the positioning strip. The auxiliary support plate is horizontally positioned on the outer surface of the I-beam and is integrally formed, providing a stable support platform for the protective plate. The connecting through holes on the auxiliary support plate facilitate the connection and fixation of the protective plate to the positioning seat, making the installation of the protective plate more reliable.

[0014] Optionally, the protective panel includes a connecting inner panel, a protective middle panel, and an outer trim panel. The connecting inner panel and the outer trim panel are installed on both sides of the protective middle panel, and both the connecting inner panel and the outer trim panel are fixedly connected to the protective middle panel.

[0015] By adopting the above technical solution, the protective panel employs a three-layer structure: an inner connecting panel, a middle protective panel, and an outer decorative panel. The inner connecting panel is used to connect and fix the panel to the positioning seat, ensuring the stability of the connection between the protective panel and the wall frame. The middle protective panel can be made of different materials according to different needs, providing multiple protective functions. The outer decorative panel enhances the aesthetics of the exterior wall, making the building's appearance cleaner and more beautiful. The three-layer structure works together to ensure both protective performance and aesthetic appeal.

[0016] Optionally, the auxiliary bracket includes a central seat plate and an outer support rod, wherein the outer support rod is evenly installed on the outer side of the central seat plate, and the outer support rod and the central seat plate are integrally formed.

[0017] By adopting the above technical solution, the central seat plate and outer support rod of the auxiliary bracket are integrally formed. This structural design gives the auxiliary bracket high structural strength and stability. The outer support rods are evenly installed on the outer side of the central seat plate, which can effectively distribute the force between adjacent wall frames, enhance the stability of the entire external wall protection structure, and prevent the wall frames from deforming due to uneven force.

[0018] Optionally, a reinforcing strip is installed between the outer support rods. The reinforcing strip is arc-shaped, and both ends of the reinforcing strip are fixedly connected to the outer support rods.

[0019] By adopting the above technical solution, the arc-shaped reinforcing strips installed between the outer support rods further enhance the structural strength of the auxiliary bracket. The arc-shaped reinforcing strips can effectively distribute the pressure borne by the outer support rods, prevent the outer support rods from deforming or breaking, improve the load-bearing capacity of the auxiliary bracket, and thus enhance the stability and safety of the entire external wall protection structure.

[0020] Optionally, the protective middle plate is made of thermal insulation material.

[0021] By adopting the above technical solution, the protective middle panel is made of thermal insulation material, which can effectively reduce heat exchange between the inside and outside of the building, play a role in thermal insulation, reduce the building's energy consumption, and improve energy efficiency. At the same time, the thermal insulation material can also improve the indoor thermal environment and enhance living comfort.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The design of the positioning slots, positioning seats, and other structures simplifies and speeds up the installation of components such as the protective panels, reducing construction time and labor costs. The three-layer structure of the protective panels and the use of insulation materials in the middle protective panel not only provide physical protection for the exterior walls but also achieve thermal insulation, improving the overall performance of the building. Simultaneously, the rational design and coordination of components such as the wall frame and auxiliary brackets enhance the stability and load-bearing capacity of the entire exterior wall protection structure, enabling it to withstand certain external impacts and environmental changes, thus ensuring the safety and durability of the building.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a prefabricated exterior wall structure. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, a prefabricated exterior wall structure includes a main wall 1. Several sets of wall frames 2 are evenly arranged on the outer surface of the main wall 1, with the wall frames 2 arranged parallel to each other and fixedly connected to the main wall 1. Auxiliary brackets 5 are also installed between adjacent wall frames 2, with both sides of the auxiliary brackets 5 fixed to the wall frames 2. Several positioning slots 20 are arranged from top to bottom on the outer surface of the wall frames 2, with positioning seats 3 inserted into each slot 20. The positioning seats 3 engage and are fixed to the wall frames 2. Protective plates 4 are also installed on the outer surface of the wall frames 2, with both ends of the protective plates 4 fixedly connected to the positioning seats 3. By adopting the above technical solution, and by setting wall frames 2 on the main wall 1, with the wall frames 2 parallel to each other and fixedly connected to the main wall 1, the stability of the basic frame of the entire exterior wall protection structure is ensured. The wall frames 2 are fixedly installed on the main wall 1 by bolts and other mechanisms, facilitating the hanging and installation of the protective plates 4 via the wall frames 2. Auxiliary brackets 5 are installed between adjacent wall frames 2, further enhancing the stability of the structure and ensuring that several wall frames 2 can form a unified structure. The auxiliary brackets 5 and the wall frames 2 can be fixed together by welding. The cooperation between the positioning slots 20 and the positioning seats 3 on the wall frames 2 makes the installation of the protective plate 4 more convenient, enabling quick and accurate positioning and fixing of the protective plate 4, thus improving construction efficiency. At the same time, the protective plate 4 can protect the external wall, preventing external factors from eroding the main wall 1 and extending the service life of the main wall 1.

[0032] Reference Figure 3 and Figure 4 As shown, the wall frame 2 includes a main frame plate 21 and side ear seats 22. The side ear seats 22 are symmetrically installed on both sides of the main frame plate 21, and are integrally formed with the main frame plate 21. The wall frame 2 adopts a structure where the main frame plate 21 and side ear seats 22 are integrally formed. This design not only enhances the structural strength of the wall frame 2 itself, but also facilitates the fixed installation of the wall frame 2 to the main wall 1, improving the stability and firmness of the installation. The integral forming process also reduces assembly steps in the production process, lowering production costs. The main frame plate 21 of the wall frame 2 can be made of high-strength steel, such as Q345 steel, which has high strength and toughness and can withstand greater external forces. Two sets of positioning strips 201 are symmetrically installed in the positioning slots 20, and the positioning strips 201 are integrally formed with the main frame plate 21. The positioning strips 201, which are symmetrically installed in the positioning slot 20, are integrally formed with the main frame plate 21. The positioning strips 201 can accurately position and guide the positioning seat 3, ensuring that the positioning seat 3 can be accurately inserted into the positioning slot 20 and can be tightly engaged after insertion, preventing the positioning seat 3 from shaking or shifting, thereby ensuring the stability of the installation of the protective plate 4.

[0033] Reference Figure 3 and Figure 5As shown, the positioning base 3 includes an I-beam base 31 and an auxiliary support plate 32. The I-beam base 31 is inserted into the positioning slot 20, and the auxiliary support plate 32 is horizontally disposed on the outer surface of the I-beam base 31 and is integrally formed with the I-beam base 31. Connecting through holes 321 are provided at both ends of the auxiliary support plate 32. The design of the I-beam base 31 of the positioning base 3 allows it to be tightly inserted into the positioning slot 20 and securely engaged with the positioning strip 201. The auxiliary support plate 32, horizontally disposed on the outer surface of the I-beam base 31 and integrally formed, provides a stable support platform for the protective plate 4. The connecting through holes 321 on the auxiliary support plate 32 facilitate the connection and fixation of the protective plate 4 to the positioning base 3, making the installation of the protective plate 4 more reliable. The I-beam base 31 and the auxiliary support plate 32 of the positioning base 3 can be made of engineering plastics, such as polycarbonate (PC), which have good mechanical properties and chemical corrosion resistance.

[0034] Reference Figure 1 and Figure 6 As shown, the protective panel 4 includes a connecting inner panel 41, a protective middle panel 42, and an outer decorative panel 43. The connecting inner panel 41 and the outer decorative panel 43 are installed on both sides of the protective middle panel 42, and both are fixedly connected to the protective middle panel 42. The protective panel 4 adopts a three-layer structure of connecting inner panel 41, protective middle panel 42, and outer decorative panel 43. The connecting inner panel 41 is used to connect and fix with the positioning seat 3, ensuring the stability of the connection between the protective panel 4 and the wall frame 2. The protective middle panel 42 can be made of different materials according to different needs, providing multiple protective functions. The outer decorative panel 43 can enhance the aesthetics of the exterior wall, making the building appearance neater and more beautiful. The three-layer structure works together to ensure both protective performance and aesthetics. The protective middle panel 42 is made of thermal insulation material. The use of thermal insulation material in the protective middle panel 42 can effectively reduce heat exchange between the inside and outside of the building, playing a role in thermal insulation, reducing the building's energy consumption, and improving energy efficiency. At the same time, the thermal insulation material can also improve the indoor thermal environment and enhance living comfort. The inner panel 41 and outer trim panel 43 of the protective panel 4 can be made of high-strength fiber-reinforced plastics, such as glass fiber reinforced plastic (GFRP), which are lightweight, high-strength, and corrosion-resistant. The protective middle panel 42 uses insulation materials, such as polyurethane foam, which has excellent insulation performance.

[0035] Reference Figure 1 and Figure 2As shown, the auxiliary bracket 5 includes a central base plate 51 and outer support rods 52. The outer support rods 52 are evenly installed on the outer surface of the central base plate 51, and the outer support rods 52 and the central base plate 51 are integrally formed. The central base plate 51 and the outer support rods 52 of the auxiliary bracket 5 can be made of aluminum alloy, such as 6061 aluminum alloy, which has the advantages of light weight, high strength, and corrosion resistance. The integral formation of the central base plate 51 and the outer support rods 52 of the auxiliary bracket 5 gives the auxiliary bracket 5 high structural strength and stability. The even installation of the outer support rods 52 on the outer surface of the central base plate 51 can effectively distribute the force between adjacent wall frames 2, enhance the stability of the entire external wall protection structure, and prevent the wall frames 2 from deforming due to uneven force. Reinforcing strips 521 are installed between the outer support rods 52. The reinforcing strips 521 are arc-shaped, and both ends of the reinforcing strips 521 are fixedly connected to the outer support rods 52. The arc-shaped reinforcing strips 521 installed between the outer support rods 52 further enhance the structural strength of the auxiliary bracket 5. The arc-shaped reinforcing strips 521 effectively distribute the pressure borne by the outer support rods 52, preventing deformation or breakage, and improving the load-bearing capacity of the auxiliary bracket 5, thereby enhancing the stability and safety of the entire external wall protection structure. The reinforcing strips 521 can be made of stainless steel, such as 304 stainless steel, and their arc-shaped design effectively enhances the structural strength of the auxiliary bracket 5.

[0036] The implementation principle of a prefabricated exterior wall structure according to an embodiment of this application is as follows: During the actual installation of the wall frame 2, firstly, the installation position of the wall frame 2 is determined on the outer side of the main wall 1 according to design requirements. Expansion bolts are used to fix the side lugs 22 of the wall frame 2 to the main wall 1, ensuring that the wall frames 2 are parallel and securely installed. During installation, the verticality and horizontality of the wall frame 2 must be ensured, with errors controlled within a minimal range to guarantee the installation accuracy of subsequent components. Then, the auxiliary brackets 5 are installed. After the adjacent wall frames 2 are installed, the auxiliary brackets 5 are installed between adjacent wall frames 2. Then, the positioning seats 3 are installed sequentially in the positioning slots 20. Finally, the protective plates 4 are installed between the positioning seats 3, and locked together by screws passing through the auxiliary brackets 32 and the protective plates 4. By installing the protective plates 4 layer by layer, the installation of the entire prefabricated exterior wall protection structure is completed.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
