Description

Technical Field

[0001] This utility model belongs to the field of interior decoration, specifically a prefabricated modular functional wall with high load-bearing capacity. Background Technology

[0002] In industries such as interior design, commercial space display, and exhibition exhibitions, functional walls not only need to meet the basic requirements of space division, but also need to support heavy-duty objects such as suspended furniture, display props, and electronic display equipment. Currently, the technical solutions for achieving this type of functional wall in the industry mainly fall into two categories:

[0003] The first type is on-site construction walls using a square tube welded frame. After marking the structural wall surface, galvanized square tubes of various sizes (60×40×3mm, 80×40×3mm, 120×60×4mm, etc.) are used as the vertical and horizontal framework. These are pre-assembled using angle brackets and expansion bolts. The joints between the vertical and horizontal square tubes are then reinforced by on-site welding. After welding, the surface is polished and coated with anti-rust paint. Fire-retardant plywood and decorative panels are then fixed layer by layer to the outside of the square tubes. Finally, a second marking is made based on the internal square tube positions for attaching suspended furniture. While this method achieves high load-bearing capacity through the welding of thick-walled square tubes, the on-site welding operation is difficult, quality control is challenging, and welders must carry welding machines at heights, posing high safety risks and preventing truly rapid assembly.

[0004] The second type is prefabricated partition walls using conventional light steel keel. These walls are framed by vertical keels, top and bottom keels, and continuous horizontal bracing, and are cut and assembled on-site before being covered with panels on both sides. While this type of partition wall achieves dry assembly and overcomes the drawbacks of the first type of wall construction, it is essentially a space partition component due to limitations in keel specifications and panel thickness. According to the "Technical Standard for Prefabricated Interior Decoration" JGJ / T 491-2021, when the weight of a fixed object on a partition wall or wall exceeds 15kg, reinforcement measures should be taken and the fixing points should be clearly defined. However, the keel spacing, fixing method, and stress distribution of conventional light steel keel partition walls are difficult to directly meet the requirements for heavy-duty hanging. If heavy objects such as televisions, bookshelves, and floating cabinets need to be hung on the wall, the hanging point positions must be determined in advance during the design phase, and fixing points must be pre-set at the corresponding keel locations, or reinforcing plates should be added behind the wall panels, and steel hangers should be pre-embedded to anchor the load to the main structure. This means that if conventional light steel keel partition walls are to have high load-bearing capacity, they still need to rely on a lot of on-site secondary processing and reinforcement work, and have not achieved true integrated prefabrication. Utility Model Content

[0005] The present invention aims to provide a prefabricated modular functional wall with high load-bearing capacity to solve the problems in the existing technology that heavy-load hanging relies on a large amount of on-site secondary processing and reinforcement, and cannot achieve true integrated prefabrication.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A prefabricated modular functional wall with high load-bearing capacity includes a top keel, a bottom keel, vertical keels, and a through horizontal bracing keel that form the wall frame; the top of the vertical keel is fixedly connected to the top keel, and the bottom of the vertical keel is fixedly connected to the bottom keel; the through horizontal bracing keel is fixedly connected to the vertical keel, and also includes reinforcing keels and heavy-duty hanging connectors;

[0008] The reinforcing keel is fitted onto the outside of the vertical keel and is fixedly connected to the vertical keel by a heavy-duty mounting connector.

[0009] As a limitation of this utility model: the heavy-duty mounting connector includes a through-bolt and a rivet nut; a rivet nut is riveted into the pre-punched hole of the vertical keel and the pre-punched hole of the reinforcing keel, the through-bolt passes through the vertical keel and the reinforcing keel, and the through-bolt has two threaded holes for the rivet nuts in its shaft.

[0010] As a further limitation of this utility model: the heavy-duty mounting connector also includes a support bracket and a locking nut. The support bracket is made of metal material, and a vertical keel, a reinforcing keel and the support bracket are inserted through one end of the through screw rod and fastened by the locking nut.

[0011] As a further definition of this utility model: the longitudinal section of the support bracket is zigzag-shaped, including a wall-attached section, a transition section and a support section that are bent and connected in sequence. The wall-attached section is attached to the surface of the reinforcing keel and fixed by a locking nut; the transition section extends horizontally away from the reinforcing keel; and the support section is located at the end of the transition section away from the wall-attached section.

[0012] As a further definition of the present invention: the supporting section includes a first extension section and a second extension section connected in sequence, the first extension section extending vertically upward from the transition section, and the second extension section extending obliquely upward to the right from the first extension section.

[0013] As another limitation of this utility model: the reinforcing keel is made of 0.8mm Q550D steel by bending, and its longitudinal section is U-shaped. The reinforcing keel is fastened to the outer periphery of the vertical keel.

[0014] As a further limitation of this utility model: the U-shaped opening of the reinforcing keel and the U-shaped opening of the vertical keel are engaged with each other, so that the reinforcing keel and the vertical keel are joined together to form a square cross section.

[0015] As a further limitation of this utility model: the top keel, the bottom keel and the vertical keel are all made of 0.8mm Q550D steel by bending, and their longitudinal sections are all U-shaped.

[0016] As another limitation of this utility model: the top keel and the vertical keel, and the ground keel and the vertical keel are all fixedly connected by countersunk self-tapping screws.

[0017] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0018] (1) This utility model uses a wall frame assembled with a top keel, a bottom keel, a vertical keel and a through horizontal bracing keel, and a reinforcing keel is fitted on the outside of the vertical keel. The reinforcing keel and the vertical keel are fixedly connected by heavy-duty hanging connectors, so that the assembly structure and the load-bearing structure are integrated in the same keel frame in the factory. This solves the problems of difficult operation, difficult quality control and high-altitude operation safety risks of on-site welding frame. At the same time, it overcomes the defects of conventional light steel keel partition walls that still need to rely on a lot of on-site processing and reinforcement for heavy-duty hanging, and realizes true integrated prefabrication.

[0019] (2) The heavy-duty mounting connector adopts through screws and rivets riveted to the pre-punched holes of the vertical keel and the reinforcing keel. The entire set of load-bearing connection nodes can be pre-embedded and pre-fabricated in the factory at one time, without the need for on-site welding and drilling. This not only eliminates the safety hazards caused by welding operations, but also fundamentally ensures the positioning accuracy of the heavy-duty mounting points, effectively avoiding the misalignment failure and load-bearing safety hazards caused by the position deviation of the furniture mounting later.

[0020] (3) The heavy-duty hanging connector is further configured with support hangers and locking nuts. The longitudinal section of the support hanger is in the shape of a broken line, including the wall-attached section, transition section and support section connected by bending in sequence. This structure can stably support the suspended furniture and display props. The hanging load is evenly transferred to the through bolt through the locking nut, and then dispersed to the local reinforcement frame composed of the reinforcing keel and the vertical keel, which significantly improves the local bending resistance and overall load-bearing capacity of the wall.

[0021] (4) The keel, the top keel, the bottom keel and the vertical keel are all made of 0.8mm Q550D steel and the longitudinal section is U-shaped. The components are highly standardized and can be cut, punched and pre-assembled in the factory. On site, the top keel, the bottom keel and the vertical keel can be fixedly connected by countersunk self-tapping screws to complete the module splicing. The construction process is greatly simplified, the construction period is significantly shortened and the overall construction cost is effectively reduced.

[0022] In summary, this utility model integrates the wall frame, reinforcing keel, and heavy-duty mounting connectors into one unit, achieving a synergistic unity between dry assembly of the wall structure and high load-bearing capacity mounting, simplifying on-site secondary processing and reinforcement steps; this utility model is applicable to industries such as interior decoration, commercial space display, and exhibition display.

Detailed Implementation

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0030] The directional terms or positional relationships such as "up," "down," "left," and "right" used in the embodiments are based on the drawings in this utility model specification. Figure 4 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0031] like Figures 1-4 As shown, this embodiment includes a top joist 1, a bottom joist 2, vertical joists 3, and a through horizontal brace 4 constituting the wall frame. The top of the vertical joist 3 is fixedly connected to the top joist 1, and the bottom is fixedly connected to the bottom joist 2; the through horizontal brace 4 is fixedly connected to the vertical joists 3. This wall frame is used to provide overall support for the wall and space division. This part is the same as the prior art.

[0032] The innovation of this embodiment lies in the addition of a reinforcing keel 5 and a heavy-duty mounting connector. Specifically, a reinforcing keel 5 is added to the existing light steel keel frame, fitted onto the outside of the vertical keel 3. The reinforcing keel 5 is fixedly connected to the vertical keel 3 through the heavy-duty mounting connector. This integrates the assembly structure and the load-bearing structure into the same keel frame in the factory, achieving the effect of rapid assembly and stable heavy load-bearing by shipping as a complete functional module and only requiring module splicing on site.

[0033] I. Heavenly Dragon Bone 1, Earthly Dragon Bone 2, Vertical Dragon Bone 3, and Through Horizontal Bracing Dragon Bone 4;

[0034] This structure is the same as the existing structure. For example... Figure 1 As shown, the top joists 1, bottom joists 2, and vertical joists 3 are all made of 0.8mm Q550D steel through bending, and their longitudinal sections are all U-shaped. Their surfaces are coated with an aluminum-zinc coating for corrosion resistance. The aluminum-zinc coating process is existing technology. Top joists 1 and bottom joists 2 are arranged parallel to each other vertically and face each other, forming the upper and lower reference frames of the wall frame. Top joists 1 and vertical joists 3, and bottom joists 2 and vertical joists 3 are fixedly connected using countersunk self-tapping screws. This U-shaped cross-section combined with the countersunk self-tapping screw connection method ensures the overall flatness and structural stability of the frame, achieves dry assembly, eliminates on-site welding, reduces construction difficulty and safety risks, and facilitates standardized prefabrication in the factory.

[0035] Multiple vertical keels 3 are arranged in a row to bear the vertical load of the wall and provide the main load-bearing base for subsequent hanging loads. The U-shaped cross-section design gives the keel itself a certain bending stiffness, while the two side walls of the U shape provide operation space for subsequent fastening connection with the reinforcing keel 5 and cooperation with heavy-duty hanging connectors.

[0036] The through-bracing keel 4 is used to connect the vertical keels 3. Multiple through-bracing keels 4 are set horizontally. Their function is to enhance the lateral stiffness of the overall frame, prevent the vertical keels 3 from undergoing lateral buckling deformation, ensure that multiple vertical keels 3 work together to bear the force, and improve the overall resistance to lateral displacement and stability of the wall.

[0037] II. Strengthen the keel 5;

[0038] like Figure 1-3 As shown, the reinforcing keel 5 is made of 0.8mm Q550D steel through bending, with a U-shaped longitudinal section. Its surface is coated with an aluminum-zinc plating for corrosion resistance. The reinforcing keel 5 is fitted over the vertical keel 3; specifically, the U-shaped opening of the reinforcing keel 5 covers the U-shaped opening of the vertical keel 3, meaning the U-shaped opening of the vertical keel 3 extends into the U-shaped opening of the reinforcing keel 5. After assembly, as shown... Figure 3As shown, it has an approximately square structure. Pre-punched holes are respectively formed on the reinforcing keel 5 and the vertical keel 3, located on two opposite folded edges. The two are fixedly connected as a whole by a heavy-duty mounting connector. In this embodiment, the diameter of the pre-punched hole is 9.5 mm.

[0039] The function of reinforcing keel 5 is to structurally strengthen the local stress nodes of vertical keel 3, forming a local high load-bearing section. This enables the light steel keel frame, originally used only for space partitioning, to directly support heavy objects. Because reinforcing keel 5 and vertical keel 3 are locked together via heavy-duty mounting connectors to form a composite load-bearing section with double-layer keel superposition, its local bending and shear resistance is significantly improved. This eliminates the need for an additional thick-walled square tube welded frame, meeting the safe mounting requirements for suspended furniture, display props, and other heavy objects. Reinforcing keel 5 can be configured in four height specifications: 300mm, 400mm, 500mm, and 600mm, depending on site requirements.

[0040] III. Heavy-duty mounting connectors;

[0041] like Figure 4 As shown, the heavy-duty mounting connector includes a through bolt 6, a rivet nut 7, a support bracket 8, and a locking nut 9.

[0042] In the pre-punched holes of the vertical keel 3 and the reinforcing keel 5, a rivet nut 7 is pre-riveted into each hole, with the threaded holes of the two rivet nuts 7 coaxially aligned. A through-bolt 6 passes through the vertical keel 3 and the reinforcing keel 5, its body passing through the threaded holes of the two rivet nuts 7, thus fastening the vertical keel 3 and the reinforcing keel 5 together. The rivet nuts 7 are pre-embedded and riveted in the factory, eliminating the need for on-site drilling or welding, ensuring high positioning accuracy and stable load-bearing performance.

[0043] The support bracket 8 is made of metal, preferably hot-dip galvanized Q550D steel. A vertical keel 3, a reinforcing keel 5, and the support bracket 8 are threaded through one end (the right end) of the through-bolt 6 and secured with a locking nut 9. Specifically, the longitudinal section of the support bracket 8 is polygonal, comprising a wall-mounted section 10, a transition section 11, and a supporting section 12 connected by successive bends. The wall-mounted section 10 is attached to the surface of the reinforcing keel 5. One end of the through-bolt 6 is threaded through the vertical keel 3, the reinforcing keel 5, and the wall-mounted section 10, and the support bracket 8 is secured to the reinforcing keel 5 with a locking nut 9. The transition section 11 extends horizontally from the upper end of the wall-mounted section 10 away from the reinforcing keel 5, and the supporting section 12 is located at the end of the transition section 11 away from the wall-mounted section 10 (i.e., the right end of the transition section 11). The supporting section 12 includes a first extension section 13 and a second extension section 14 connected in sequence. The first extension section 13 extends vertically upward from the transition section 11, and the second extension section 14 extends obliquely to the upper right from the first extension section 13. This zigzag structure enables the supporting bracket 8 to stably support externally mounted objects such as suspended furniture, display props, or electronic display devices. The load is transferred to the through bolt 6, and then distributed to the locally reinforced frame formed by the reinforcing keel 5 and the vertical keel 3, and finally transferred to the main building structure, achieving safe load transfer and uniform distribution.

[0044] The heavy-duty mounting connectors are pre-embedded and pre-assembled in the factory, simplifying on-site secondary processing and reinforcement steps. This eliminates the safety hazards caused by welding operations and fundamentally ensures the positioning accuracy of the heavy-duty mounting points, effectively avoiding misalignment failures and load-bearing safety hazards caused by point deviations in furniture mounting later.

[0045] This embodiment integrates a light steel keel frame, a sleeved reinforcing keel 5, and a pre-embedded heavy-duty mounting connector into a single unit. The components are highly standardized, allowing for factory cutting, punching, riveting with nuts 7, and pre-assembly, resulting in a complete functional module. During on-site construction, only the modules (i.e., top keel 1, bottom keel 2, vertical keel 3, reinforcing keel 5, through bolts 6, support brackets 8, and locking nuts 9) need to be assembled to complete the wall frame construction. This significantly simplifies the construction process, effectively reducing overall construction costs and truly achieving the synergistic unity of dry assembly of the wall structure and high-load-bearing mounting.

[0046] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
