Description
Technical Field
[0001] This utility model relates to the field of shop sign installation technology, and in particular to a shop sign installation mechanism. Background Technology
[0002] As an important carrier of commercial signage, the technological development of shop sign installation structures has evolved from simple to complex, and from single-function to a combination of aesthetics and stability. Early shop sign installation structures were relatively simple, only meeting basic hanging requirements. As the market's demands for the appearance and durability of signs increased, installation structures using metal frames combined with decorative panels gradually developed.
[0003] Currently, the common installation structure for shop signs uses a welded angle steel frame combined with aluminum composite panel cladding. Specifically, construction workers need to cut and weld the angle steel on-site to build the supporting frame for the sign, and then cover the frame surface with aluminum composite panels to achieve an aesthetically pleasing effect.
[0004] While the aforementioned installation methods meet the installation needs of shop signs to some extent, practical applications reveal problems such as low installation efficiency and maintenance difficulties. On the one hand, installation efficiency is low. Because on-site operations such as cutting and welding angle steel are required, not only are the technical requirements for construction workers high, but the limitations of the site environment and tools also lead to a lengthy installation process, typically taking no less than two hours for a single point. On the other hand, maintenance difficulties are prominent. When the lettering on the sign needs to be replaced, the entire aluminum composite panel must be removed. This not only increases the workload and time cost of maintenance but may also damage the panel, further increasing maintenance costs and failing to meet the actual need for convenient maintenance of shop signs.
[0005] Therefore, there is an urgent need for a new type of shop sign installation organization to solve the problems of low installation efficiency and difficulty in replacing and maintaining fonts in the current shop sign installation structure. Utility Model Content
[0006] The main purpose of this utility model is to propose a shop sign installation mechanism, which aims to solve the problems of low installation efficiency and difficulty in font replacement and maintenance of current shop sign installation structures.
[0007] To achieve the above objectives, the shop sign installation mechanism proposed in this utility model includes a base frame, a decorative panel layer, and a sign shell. The base frame is ring-shaped and is used for installation in the shop sign installation area. The decorative panel layer includes multiple panel components, and the four edges of the panel components are provided with folded edge structures. Adjacent panel components are interlocked with each other through the folded edge structures to assemble the decorative panel layer. The decorative panel layer is detachably connected to the base frame. The sign shell is detachably connected to the outer surface of the decorative panel layer.
[0008] In one embodiment, the folded edge structure has a first bend and a second bend, the first bend being connected to the second bend, and the included angle between the first bend and the second bend being 30° to 60°.
[0009] In one embodiment, the panel assembly is configured as a plate-like structure with continuous raised and recessed textures; and / or, the first bend and the second bend are integrally formed.
[0010] In one embodiment, the folded edge structure is further provided with a spring clip and a slot, and in two adjacent panel assemblies, the spring clip of one panel assembly engages with the slot of the other panel assembly.
[0011] In one embodiment, a magnetic element is provided on the back of the sign shell, and the panel assembly is made of ferromagnetic material. The sign shell is magnetically attracted to the panel assembly through the magnetic element.
[0012] In one embodiment, the back of the sign shell is also provided with a connector, and the panel assembly is provided with a slot, and the connector is inserted into the slot.
[0013] In one embodiment, the connector is waterproof and has a first through hole, and the slot has a second through hole; the interior of the sign shell is provided with a light strip, which has a power cord that passes through the first through hole and the second through hole in sequence and is electrically connected to an external power source.
[0014] In one embodiment, a nut is embedded in the decorative panel layer, and the shop sign installation mechanism includes a self-tapping screw that passes through the front of the base frame, the decorative panel layer, and is screwed to the nut.
[0015] In one embodiment, a slide rail and a folding door are provided on the back of the base frame. The folding door slides on the slide rail, and the folding door, the base frame, and the decorative panel layer together form a maintenance cavity.
[0016] In one embodiment, the basic frame includes multiple main keels, multiple secondary keels, and multiple cross-bracing structures. The multiple main keels form a ring-shaped main structure of the basic frame. The multiple secondary keels are arranged at intervals within the main structure of the basic frame, and the multiple secondary keels divide the main structure of the basic frame into multiple frame grids. The multiple cross-bracing structures are correspondingly arranged within the multiple frame grids to provide diagonal support to the frame grids. Both the main keels and secondary keels are made of hollow galvanized square steel.
[0017] This utility model's technical solution achieves convenient installation, flexible maintenance, and modular assembly of shop signs through the cooperation of a basic frame, decorative panel layer, and sign shell. The basic frame, in a ring shape, is installed in the shop sign installation area, providing a stable foundation support structure for the entire installation mechanism. Furthermore, the basic frame can be prefabricated, eliminating the need for on-site welding and saving on-site installation time. The decorative panel layer is assembled from multiple panel components that interlock with each other via a folded edge structure. This interlocking method eliminates the need for additional tools or complex installation steps, significantly simplifying the assembly process and improving installation efficiency. Furthermore, the interlocking of adjacent panel components via the folded edge structure creates a tight connection, enhancing the overall structural strength of the decorative panel layer. The decorative panel layer is detachably connected to the base frame, and the sign shell is detachably connected to the decorative panel layer. This allows for easy installation and removal of the decorative panel layer and sign shell from the base frame. If a panel component or sign shell is damaged, the entire sign does not need to be disassembled and replaced; only the damaged component or shell needs to be removed and replaced, greatly reducing maintenance costs and difficulty and improving maintenance efficiency. In addition, the design of the decorative panel layer, formed by the interlocking of panel components via the folded edge structure, allows for flexible adjustment of the size and shape to meet actual needs, improving the applicability and flexibility of the shop sign installation mechanism.
[0018] Overall, the shop sign installation mechanism of this utility model achieves efficient installation and convenient maintenance of the sign shell by forming a decorative panel layer through a folded edge structure and a detachable connection scheme between various components. This reduces maintenance costs and difficulties, while improving installation efficiency and structural stability, and meets the needs of practical applications for the convenience, flexibility and practicality of shop sign installation mechanisms.

[0033] As an important carrier of commercial signage, the technological development of shop sign installation structures has evolved from simple to complex, and from single-function to a combination of aesthetics and stability. Early shop sign installation structures were relatively simple, only meeting basic hanging requirements. As the market's demands for the appearance and durability of signs increased, installation structures using metal frames combined with decorative panels gradually developed.
[0034] Currently, the common installation structure for shop signs uses a welded angle steel frame combined with aluminum composite panel cladding. Specifically, construction workers need to cut and weld the angle steel on-site to build the supporting frame for the sign, and then cover the frame surface with aluminum composite panels to achieve an aesthetically pleasing effect.
[0035] While the aforementioned installation methods meet the installation needs of shop signs to some extent, practical applications reveal problems such as low installation efficiency and maintenance difficulties. On the one hand, installation efficiency is low. Because on-site operations such as cutting and welding angle steel are required, not only are the technical requirements for construction workers high, but the limitations of the site environment and tools also lead to a lengthy installation process, typically taking no less than two hours for a single point. On the other hand, maintenance difficulties are prominent. When the lettering on the sign needs to be replaced, the entire aluminum composite panel must be removed. This not only increases the workload and time cost of maintenance but may also damage the panel, further increasing maintenance costs and failing to meet the actual need for convenient maintenance of shop signs.
[0036] Therefore, there is an urgent need for a new type of shop sign installation organization to solve the problems of low installation efficiency and difficulty in replacing and maintaining fonts in the current shop sign installation structure.
[0037] To address the aforementioned problems, this utility model proposes a shop sign installation mechanism.
[0038] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the shop sign installation mechanism includes a base frame 1, a decorative panel layer 2, and a sign shell 3. The base frame 1 is ring-shaped and is used for installation in the shop sign installation area. The decorative panel layer 2 includes multiple panel components 21. The four edges of the panel components 21 are provided with folded edge structures 211. Adjacent panel components 21 are snapped together by the folded edge structures 211 to assemble the decorative panel layer 2. The decorative panel layer 2 is detachably connected to the base frame 1. The sign shell 3 is detachably connected to the outer surface of the decorative panel layer 2.
[0039] The technical solution of this utility model achieves convenient installation, flexible maintenance, and modular assembly of shop signs through the cooperation of the basic frame 1, decorative panel layer 2, and sign shell 3. The basic frame 1 is ring-shaped and installed in the shop sign installation area, providing a stable foundation support structure for the entire installation mechanism; moreover, the basic frame 1 can be pre-fabricated, eliminating the need for on-site welding and saving on-site installation time. The decorative panel layer 2 is assembled from multiple panel components 21 that are interlocked with each other through folded edge structures 211 around the perimeter. This interlocking method eliminates the need for additional tools or complex installation steps, significantly simplifying the assembly process of the decorative panel layer 2 and improving installation efficiency. At the same time, adjacent panel components 21 can form a tight connection through the folded edge structures 211, enhancing the overall structural strength of the decorative panel layer 2. The decorative panel layer 2 and the base frame 1, as well as the sign shell 3 and the decorative panel layer 2, are all connected in a detachable manner, allowing the decorative panel layer 2 and the sign shell 3 to be easily installed onto or removed from the base frame 1. When a panel component 21 of the decorative panel layer 2 or the sign shell 3 is damaged, it is not necessary to disassemble and replace the entire sign; only the damaged panel component 21 or the sign shell 3 needs to be disassembled and replaced individually, greatly reducing maintenance costs and difficulty and improving maintenance efficiency. In addition, the panel assembly 21 is designed to form the decorative panel layer 2 by snap-fitting the edge structure 211, which allows the size and shape of the decorative panel layer 2 to be flexibly adjusted according to actual needs, thus improving the applicability and flexibility of the shop sign installation mechanism.
[0040] Overall, the shop sign installation mechanism of this utility model achieves efficient installation and convenient maintenance of the sign shell 3 by using the folded edge structure 211 to form the decorative panel layer 2 and the detachable connection scheme between various components. This reduces maintenance costs and difficulties, while improving installation efficiency and structural stability, and meets the needs of practical applications for the convenience, flexibility and practicality of the shop sign installation mechanism.
[0041] The basic frame 1 can be connected to the shop sign installation area through threaded connections, fasteners, welding, or other methods. Additionally, the sign shell 3 can be understood as an outer shell structure displaying the shop sign name, slogans, and logo in various fonts and patterns. These fonts and patterns are created through engraving, spraying, and other methods for display.
[0042] Please see Figure 2 In an embodiment of this utility model, the folded edge structure 211 has a first bending portion 2111 and a second bending portion 2112, the first bending portion 2111 and the second bending portion 2112 are connected, and the included angle between the first bending portion 2111 and the second bending portion 2112 is 30° to 60°.
[0043] In this embodiment, the folded edge structure 211 is provided with a first bending portion 2111 and a second bending portion 2112, and the included angle between the two is 30° to 60°. This angle range can effectively balance the tightness and ease of operation when adjacent panel components 21 are snapped together. Specifically, when adjacent panel components 21 are snapped together by the folded edge structure 211, the included angle of 30° to 60° ensures that the snapping structure formed by the first bending portion 2111 and the second bending portion 2112 has sufficient engagement depth to ensure that the snapped panel components 21 form a tight and stable connection, thereby enhancing the overall structural strength of the decorative panel layer 2 and preventing the panel components 21 from loosening or falling off due to external forces such as wind and vibration. At the same time, this angle range also makes it easy for operators to quickly align and complete the snapping action during installation, achieving rapid assembly of the panel components 21 without the need for special tools. During disassembly, the snapping can also be easily released by applying reasonable force, reducing the difficulty of installation and maintenance. In addition, the angle design allows the snap-fit structure to evenly distribute the load to the first bending part 2111 and the second bending part 2112 when subjected to external force, reducing local stress concentration and further improving the durability and reliability of the folded edge structure 211.
[0044] Preferably, the included angle between the first bending portion 2111 and the second bending portion 2112 can be set to 40° to 50°. By further limiting the included angle between the first bending portion 2111 and the second bending portion 2112 to 40° to 50°, this angle range can achieve better mechanical performance and ease of operation while ensuring the stability of the snap-fit structure. Compared to the wider range of 30° to 60°, the included angle of 40° to 50° can further improve the engagement depth and snap-fit precision of the snap-fit structure, thereby enhancing the connection tightness between adjacent panel components 21, effectively resisting the influence of external loads such as wind and vibration on the decorative panel layer 2, and avoiding problems such as snap-fit failure or panel loosening.
[0045] More preferably, the included angle between the first bent portion 2111 and the second bent portion 2112 can be set to 45°. The 45° angle, as a geometrically symmetrical angle, allows the normal pressure and friction generated during engagement to be evenly distributed between the first bent portion 2111 and the second bent portion 2112, minimizing local stress concentration and improving the fatigue resistance and service life of the folded edge structure 211. Furthermore, the 45° angle facilitates mold design and forming during manufacturing, reducing production difficulty and cost.
[0046] Please see Figure 1 and Figure 2 In embodiments of this utility model, the panel assembly 21 is configured as a plate-like structure with continuous convex and concave textures; and / or, the first bending portion 2111 and the second bending portion 2112 are integrally formed.
[0047] In this embodiment, the panel assembly 21 is configured as a plate-like structure with continuous raised and recessed textures. The three-dimensional geometry formed by the raised and recessed textures can significantly enhance the structural strength and deformation resistance of the panel assembly 21. When the panel is subjected to external forces such as wind and vibration, the raised and recessed textures can effectively disperse the load and suppress local stress concentration, thereby reducing the bending or denting of the panel assembly 21 and improving the overall durability of the decorative panel layer 2. At the same time, the continuous raised and recessed textures can increase the visual three-dimensional layering of the panel surface, achieve a three-dimensional decorative effect, and enhance the aesthetics of the shop sign. Furthermore, the integral molding design of the first bending portion 2111 and the second bending portion 2112 eliminates splicing gaps or welding points between the bending portions, avoiding the problem of snap-fit failure caused by weak connections, and significantly improving the overall rigidity and reliability of the folded edge structure 211. In addition, the integral molding process can simplify the processing flow, reduce the number of parts and assembly steps, reduce production and processing costs, and improve the manufacturing precision of the folded edge structure 211, ensuring the tight fit of adjacent panel components 21 when snapped together by the folded edge structure 211, further improving the assembly efficiency and structural stability of the decorative panel layer 2. The above two technical features can be used alone or in combination.
[0048] The plate-like structure with continuous embossed texture can be obtained by molding the sheet material, or by other manufacturing methods, which will not be elaborated here. Furthermore, since the first bent portion 2111 and the second bent portion 2112 are integrally formed, the included angle between them can be obtained by bending the folded edge structure 211. For example, when the included angle between the first bent portion 2111 and the second bent portion 2112 is 45°, the desired 45° angle can be obtained by bending the edge of the folded edge structure 211 by 135°; for other angles X°, it can also be obtained by bending the folded edge structure 211 by 180°-X°.
[0049] Please see Figure 2 and Figure 3 In an embodiment of this utility model, the folded edge structure 211 is also provided with a spring buckle 2113 and a slot 2114. In two adjacent panel assemblies 21, the spring buckle 2113 of one panel assembly 21 is engaged with the slot 2114 of the other panel assembly 21.
[0050] In this embodiment, the folded edge structure 211 is also provided with a spring clip 2113 and a slot 2114. In addition to the interlocking of adjacent folded edge structures 211, the connection reliability is further enhanced by the interlocking of the spring clip 2113 and the slot 2114. Specifically, by interlocking the spring clip 2113 of one panel assembly 21 with the slot 2114 of another panel assembly 21, the elastic deformation characteristics of the spring clip 2113 allow it to be easily inserted into the slot 2114 during installation by pressing. This allows for quick assembly without the need for additional tools, significantly improving the installation efficiency of the panel assembly 21. After interlocking, the spring clip 2113 and the slot 2114 form a stable mechanical engagement, effectively resisting the effects of external vibrations, wind, and other loads on the panel assembly 21, preventing loosening or detachment due to long-term external forces, and enhancing the overall connection strength and structural stability of the decorative panel layer 2. During disassembly, only a slight external force needs to be applied to the spring clip 2113 to disengage it from the slot 2114, allowing for easy separation of the panel assembly 21. This reduces the difficulty of maintenance operations and further demonstrates the convenience and reliability of the installation mechanism during assembly and maintenance. The dual-clamping mechanism, combining the interlocking of adjacent folded edge structures 211 with the spring clip 2113 and the slot 2114, further enhances the reliability of the connection, ensuring the overall connection strength and structural stability of the decorative panel layer 2.
[0051] In an embodiment of this utility model, the back of the sign shell 3 is provided with a magnetic component (not shown in the figure), the panel assembly 21 is made of ferromagnetic material, and the sign shell 3 is magnetically attracted to the panel assembly 21 through the magnetic component.
[0052] In this embodiment, the back of the sign shell 3 is equipped with a magnetic component, and the panel assembly 21 is made of ferromagnetic material. The two are detachably connected through the magnetic attraction between the magnetic component and the panel assembly 21. This magnetic connection method utilizes the magnetic attraction between the magnetic component and the ferromagnetic material. When installing the sign shell 3, no additional connecting parts or tools such as screws or clips are needed. Simply align the sign shell 3 with the panel assembly 21 and bring it close, and it can be quickly and firmly attached by magnetic attraction, which significantly simplifies the installation process and improves installation efficiency. When disassembling, only an external force opposite to the direction of magnetic attraction needs to be applied to separate the sign shell 3 from the panel assembly 21. The operation is convenient and labor-saving, greatly reducing the difficulty of disassembly and installation during maintenance. Furthermore, the magnetic attraction between the magnetic components and the ferromagnetic material provides a stable connection force, effectively resisting the influence of external wind, vibration and other loads on the sign shell 3, avoiding loosening or falling off, and ensuring the reliability of the connection and structural stability between the sign shell 3 and the decorative panel layer 2. At the same time, the panel assembly 21 is made of ferromagnetic material, which can cooperate with the magnetic components by utilizing its own material properties without additional processing, simplifying the production process, reducing material and processing costs, and the ferromagnetic material is widely available and easy to obtain, further improving the practicality and economy of the installation mechanism.
[0053] In one optional implementation, the magnetic component can be a magnet, and the panel assembly 21 can be made of ferromagnetic materials such as stainless steel. Alternatively, in another optional implementation, the panel assembly 21 is provided with ferromagnetic material, and the sign shell 3 is magnetically attracted to the ferromagnetic material via the magnetic component. Thus, the panel assembly 21 can be made of other non-ferromagnetic materials, such as aluminum plates, and the magnetic attraction effect can be achieved simply by providing ferromagnetic material in a portion of the panel assembly 21. Alternatively, the panel assembly 21 can also be provided with another magnetic component, and the magnetic component on the sign shell 3 can be magnetically attracted to the magnetic component on the panel assembly 21.
[0054] In an embodiment of this utility model, the back of the sign shell 3 is also provided with a connector (not shown in the figure), and the panel assembly 21 is provided with a slot (not shown in the figure), and the connector is inserted into the slot.
[0055] In this embodiment, the connector on the back of the signboard shell 3 engages with the slot on the panel assembly 21, enabling a detachable connection between the signboard shell 3 and the panel assembly 21 through this mechanical connection structure. Specifically, during installation, simply align the connector with the slot and insert it to quickly complete the connection without the need for additional connectors or tools such as screws or glue, significantly simplifying the installation process and improving efficiency. The precise fit between the connector and the slot provides reliable mechanical positioning, ensuring the accuracy of the signboard shell 3's position during installation and preventing unevenness or connection failure due to installation deviations. The tight fit formed by the connector structure effectively resists external wind and vibration loads. The interlocking of the connector and the slot restricts relative displacement, enhancing the connection strength and structural stability between the signboard shell 3 and the panel assembly 21, preventing loosening or detachment due to external forces during long-term use. During maintenance or replacement, simply pull the connector out of the slot to easily separate the signboard shell 3 from the panel assembly 21, simplifying the operation and reducing the difficulty and time cost of maintenance. In this embodiment, by adding a plug-in and slot connection method to the magnetic engagement between the sign shell 3 and the panel assembly 21 through magnetic components, the sign shell 3 is more securely and reliably connected to the decorative panel layer 2, effectively preventing the sign shell 3 from loosening or falling off.
[0056] In an embodiment of this utility model, the connector has waterproof sealing, the connector has a first through hole, and the slot has a second through hole; the interior of the sign shell 3 is provided with a light strip (not shown in the figure), the light strip has a power cord, the power cord passes through the first through hole and the second through hole in sequence and is electrically connected to an external power source.
[0057] In this embodiment, by making the connector waterproof and airtight, and by providing a first through hole in the connector and a second through hole in the slot, and by having the power cord of the LED strip inside the sign housing 3 pass through the first through hole and the second through hole in sequence and connect it to the external power source, the waterproof and airtight connector structure effectively prevents external rainwater and moisture from entering the interior of the sign housing 3, avoiding short circuits or malfunctions of the LED strip and power cord due to moisture, and significantly improving the service life and operational reliability of the electrical components. At the same time, the cooperation between the first through hole and the second through hole provides a dedicated wiring channel for the power cord, allowing the power cord to be orderly led out from inside the sign housing 3 and connected to the external power source, avoiding safety hazards caused by exposed power cords, and the wiring method is neat and standardized, which facilitates the wiring layout during installation and troubleshooting during later maintenance. In addition, the insertion and mating of the connector and the slot itself has a mechanical connection function. Combined with the waterproof sealing design, it achieves electrical connection while taking into account structural sealing and connection stability. This ensures that the light strip can still work stably in complex outdoor environments such as humid and rainy conditions without the need for additional waterproof protection measures, which simplifies the overall structural design and reduces production costs.
[0058] In an embodiment of this utility model, a nut (not shown in the figure) is embedded in the decorative panel layer 2, and the shop sign installation mechanism includes a self-tapping screw (not shown in the figure). The self-tapping screw passes through the front of the base frame 1 and the decorative panel layer 2 and is screwed to the nut.
[0059] In this embodiment, a nut is embedded in the decorative panel layer 2, and a self-tapping screw passes through the front of the base frame 1, the decorative panel layer 2, and is screwed into the nut, achieving a detachable connection between the base frame 1 and the decorative panel layer 2. This solution utilizes the pre-embedded nut and the screwed connection of the self-tapping screw, eliminating the need for additional nut positioning or complex alignment operations during installation. The connection is quickly completed by simply screwing the self-tapping screw into the nut, significantly simplifying the installation process and improving on-site installation efficiency. Simultaneously, the screwed structure provides reliable mechanical connection strength, forming a stable rigid connection between the base frame 1 and the decorative panel layer 2, effectively resisting the impact of external wind force, vibration, and other loads on the installation mechanism, preventing loosening or detachment, and improving the structural stability of the entire shop sign installation mechanism. Furthermore, due to the detachable screwed connection, when maintenance or replacement of the decorative panel layer 2 or the base frame 1 is required, the two can be easily separated simply by unscrewing the self-tapping screw, without damaging the structure. The pre-embedded nut prevents damage to the decorative panel layer 2 caused by repeated disassembly, extending the overall service life of the installation mechanism.
[0060] Please see Figure 1 and Figure 4In an embodiment of this utility model, a slide rail 11 and a folding door 12 are provided on the back of the base frame 1. The folding door 12 is slidably mounted on the slide rail 11. The folding door 12, the base frame 1, and the decorative panel layer 2 together form a maintenance cavity.
[0061] In this embodiment, the sliding engagement of the slide rail 11 and the folding door 12 provides a convenient opening and closing channel for the maintenance cavity. Operators can quickly enter the maintenance cavity by simply sliding the folding door 12 without disassembling the decorative panel layer 2 or the sign shell 3. This significantly improves the convenience of maintaining the mechanical structure and electrical components such as power lines inside the maintenance cavity, reducing maintenance time and labor costs. Simultaneously, the maintenance cavity, enclosed by the folding door 12, the base frame 1, and the decorative panel layer 2, forms a closed, independent space, effectively protecting internal components from external dust, rain, and other corrosive elements, extending their service life. Furthermore, the folding door 12 slides onto the back of the base frame 1, without affecting the appearance integrity of the front decorative panel layer 2 and the sign shell 3, ensuring the overall aesthetics of the shop sign while organically combining maintenance functionality with structural design, thus enhancing the practicality and reliability of the installation mechanism in actual applications.
[0062] Please see Figure 1 and Figure 5 In an embodiment of this utility model, the basic frame 1 includes multiple main keels 13, multiple secondary keels 14, and multiple cross-support structures 15. The multiple main keels 13 form a ring-shaped main structure of the basic frame 1. The multiple secondary keels 14 are arranged at intervals within the main structure of the basic frame 1, and the multiple secondary keels 14 divide the main structure of the basic frame 1 into multiple frame grids. The multiple cross-support structures 15 are correspondingly arranged within the multiple frame grids to provide oblique support to the frame grids. Both the main keels 13 and the secondary keels 14 are made of hollow galvanized square steel.
[0063] In this embodiment, the basic frame 1, through the coordinated design of multiple main keels 13, secondary keels 14, and cross-bracing structures 15, combined with the selection of hollow galvanized square steel, significantly improves the overall structural strength and reduces the overall weight of the basic frame 1. The multiple main keels 13 form a ring-shaped main structure, providing a stable outer support skeleton for the basic frame 1 and ensuring the overall outline stability of the frame. The multiple secondary keels 14 are arranged at intervals within the main structure to form a frame grid, not only providing lateral and longitudinal support and reinforcement to the main keels 13, but also dividing the basic frame 1 into multiple load-bearing units, allowing external loads (such as wind pressure, gravity, etc.) to be evenly distributed to each frame grid, avoiding localized stress concentration. The corresponding cross-bracing structures 15, set within the frame grid, further enhance the deformation resistance of the frame grid through diagonal support, forming a triangular stable structure, effectively improving the wind and earthquake resistance of the basic frame 1, and ensuring the structural safety of the shop sign in complex outdoor environments. Furthermore, the main keel 13 and secondary keel 14 are made of hollow galvanized square steel. The hollow structure ensures sufficient structural strength while reducing overall weight, thus lowering material consumption and installation load. The galvanizing process gives the steel excellent corrosion resistance, effectively resisting outdoor rain and moisture, extending the service life of the foundation frame 1, reducing later maintenance costs, and facilitating processing and installation. The hollow square steel is easy to process and install, allowing for rapid assembly via welding or bolting, improving construction efficiency. This structural design and material selection combine to give the foundation frame 1 the advantages of high strength, lightweight, corrosion resistance, and ease of installation, meeting the stability and durability requirements of outdoor shop signs.
[0064] As an optional implementation, the main keel 13 and secondary keel 14 can also be treated with a triple anti-corrosion process of hot-dip galvanizing, epoxy primer, and fluorocarbon topcoat, thus forming a three-layer protective system that significantly improves the corrosion resistance and service life of the foundation frame 1. Specifically, the hot-dip galvanized layer, through electrochemical protection, forms a dense zinc-iron alloy layer on the steel surface, effectively isolating oxygen and moisture from contact with the steel substrate. Even in the event of localized damage to the galvanized layer, zinc can still protect the steel through sacrificial anode action, slowing down the corrosion process. The epoxy primer has excellent adhesion and shielding properties, filling the tiny pores on the surface of the galvanized layer, enhancing the overall sealing of the anti-corrosion system, further preventing the penetration of corrosive media, and providing a good adhesion base for the fluorocarbon topcoat. The fluorocarbon topcoat, with its excellent weather resistance, UV resistance, and chemical stability, forms a robust protective barrier on the outermost layer, effectively resisting UV radiation, acid rain, salt spray, and other erosion in the outdoor environment, preventing coating powdering, cracking, and peeling. This triple anti-corrosion treatment creates a composite protection system that not only significantly extends the service life of the main keel 13 and secondary keel 14 in harsh outdoor environments and reduces structural damage and maintenance costs caused by corrosion, but also significantly improves the overall durability and reliability of the basic frame 1 through the synergistic effect between the coatings, ensuring that the shop sign installation mechanism maintains stable structural performance during long-term use.
[0065] In addition, the connection nodes between the main keel 13 and the secondary keel 14 can be welded using CO2 gas shielded welding, and the connection nodes between the cross support structure 15 and the main keel 13 and the secondary keel 14 can also be welded using CO2 gas shielded welding. This will form a continuous and dense weld during the welding process, creating a rigid connection between the main keel 13, the secondary keel 14 and the cross support structure 15. This will ensure that the load can be evenly transferred to the entire foundation frame 1 through the weld, reducing stress concentration at each connection node and enhancing the wind and earthquake resistance and structural stability of the foundation frame 1 during long-term use.
