Description

Technical Field

[0001] The present invention relates to the field of building decoration, and in particular to a multifunctional assembled cold-bent light steel keel frame wall structure. Background Art

[0002] The current mainstream keels are mainly light steel keels and welded square tube keels. These two types of keels have relatively single uses. The light steel keel has a simple structure, but lacks overall strength. It is not as strong as the square tube keel in terms of wall stability. Its strength needs to be increased after the inorganic panel is fixed in the later stage. Due to its thin material, the overall flatness cannot be very flat; the square tube keel partition wall has better strength, but its construction process requires welding, and anti-corrosion treatment is required after welding. The strength is guaranteed, but the process is relatively complicated and the personnel requirements are relatively high. Because the square tube needs to be welded, the square tube is deformed by heat, and its flatness cannot be very flat. The above two structural forms are not convenient to disassemble after installation, and the materials cannot be reused. In addition, the types of its outer decorative panels are relatively single. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multifunctional assembled cold-bent light steel keel frame wall structure which is reusable, has a simple construction process, reliable quality and good performance.

[0004] In order to solve the above-mentioned problems, the present invention is achieved through the following technical solutions: a multifunctional assembled cold-bent light steel keel frame wall structure, which is a frame structure composed of horizontal keels and vertical keels arranged in a staggered manner along the longitude and latitude. The cross-section of the horizontal keel is an I-shaped structure, and the cross-section of the vertical keel is based on the I-shaped structure and has functional protrusions added to the upper and lower surfaces of the I-shaped structure. This structure greatly enhances the structural strength of the horizontal and vertical keels. In particular, the vertical keel has functional protrusions added to the I-shaped structure. Such multiple bends not only greatly increase the strength of the entire keel by more than 3-5 times, but also lay the foundation for a multifunctional application skeleton for the diversified use of decorative surface layers, and also reserve installation space for wall-enhanced fireproof and soundproofing materials such as rock wool gypsum board. Since the vertical keel is the main load-bearing keel, the increased strength also ensures the structural stability of the entire keel frame during use.

[0005] To facilitate rapid installation of the horizontal keel on the vertical keel, the horizontal and vertical keels are connected in a detachable manner. Specifically, the horizontal keel is provided with connecting angle fittings at both ends of the pipe opening. The connecting angle fittings include an integrally formed plug-in portion, an extension portion, and a mounting portion formed by folding the extension portion outward. The plug-in portion inserts into the pipe opening of the horizontal keel to clamp the horizontal keel, while the extension portion extends into the I-shaped groove of the vertical keel. Keel mounting holes are provided in the sidewalls of the I-shaped groove, and the mounting portion is inserted into the keel mounting holes to achieve a mounting connection between the horizontal and vertical keels. This method of attaching the horizontal keel to the vertical keel allows for rapid connection of the horizontal and vertical keels. The mortise and tenon-and-tenon connection between the horizontal and vertical keels utilizes a minimal number of screws, eliminates welding, and is fully detachable, achieving an efficient assembly process. This significantly shortens installation time and saves labor costs by more than 10 times, laying a solid foundation for the further development of assembly-based architectural decoration projects (building industrialization).

[0006] An inorganic panel is installed between two adjacent vertical purlins. The outer edge side wall of the inorganic panel fits the side wall of the functional protrusion to locate the installation position and the inorganic panel is fixed to the vertical purlin by fixing screws. Inorganic filler is filled between the inorganic panels, and a decorative layer is provided on the outside of the inorganic panel.

[0007] The decorative layer mainly has the following four structures:

[0008] Structure 1: The decorative layer comprises a portable wall panel. Wall panel hooks are located on both sides of the panel, and mounting holes are located on the top surface of the functional protrusions on the vertical studs. The hooks fit into the holes, allowing the panel to be mounted on the vertical studs. A rectangular sealing strip is sandwiched between the functional protrusions, with its upper surface abutting the outer flange of the panel. The panel is extremely convenient and quick to install and remove. After the stud frame is installed on the wall, the mounting holes on the functional protrusions on the vertical studs mate perfectly with the modular portable wall panel. This allows the panel to be installed simultaneously with the stud frame, eliminating the need for additional waiting or measuring. Furthermore, the rectangular sealing strip, made of a soft material, effectively prevents the panel from colliding with the metal studs and causing unwanted noise, while also improving the seal between the panel and the underlying inorganic panel.

[0009] Structure 2: The decorative layer is a mountable panel. A transverse panel hook is fixed to the inner surface of the mountable panel, and a transverse panel mount is fixed to the corresponding position on the outer surface of the inorganic panel. The transverse panel mount fits into the transverse panel hook, allowing the mountable panel to be mounted on the inorganic panel. A shock-absorbing pad is installed next to the transverse panel mount, which abuts against the inner surface of the mountable panel. The mountable panel can be quickly installed and removed, improving construction efficiency. The shock-absorbing pad acts as a collision buffer between the mountable panel and the inorganic panel, preventing any abnormal noise.

[0010] Structure 3: The decorative layer is a veneer decorative board, which is directly attached to the inorganic panel by adhesive. This structure greatly saves production costs and is simpler.

[0011] Structure 4: The decorative layer is a paint layer. Putty is placed between the functional protrusions, and the surface of the putty is flush with the surface of the inorganic panel. Bandage is bonded to the surface of the putty. A smoothed putty layer is applied between the inorganic panel and the bandage. The paint layer is sprayed onto the surface of the putty layer. The inorganic panel, vertical keel, and putty interface, due to their different materials, experience varying degrees of thermal expansion and contraction, which can cause cracks at the joints and affect the appearance. The bandage effectively covers the underlying cracks, ensuring the smoothness of the paint layer. The paint layer can be freely selected in various types and colors, or sprayed with patterns and text, allowing for custom customization of the decorative layer.

[0012] To facilitate the docking of the horizontal and vertical purlins, the mounting holes further comprise a top-wide, narrow-bottomed flip guide hole and a bottom-long, narrow mounting slot. The extended portion of the angled connection piece has a semi-enclosed outer profile with an opening at the bottom. Its width is equal to or slightly smaller than the width of the I-shaped groove of the vertical purlin, and its height is smaller than its width. Therefore, during installation, the horizontal purlin forms an "I"-shaped cross-section. At this point, the extended portion of the angled connection piece, inserted into the horizontal purlin, can fully extend into the groove of the vertical purlin. The horizontal purlin is then flipped 90° along its length. During this process, the mounting portion also flips simultaneously, its end gradually entering the flip guide hole. Upon completion, the horizontal purlin forms an "H"-shaped cross-section. Guided by the wide-top, narrow-bottom shape of the flip guide hole, the mounting portion falls into the bottom mounting slot, thereby achieving docking of the horizontal and vertical purlins. Of course, the hanging groove can also be designed to have a slightly tapered structure, so that the hanging part can be clamped with the hanging groove to achieve self-locking under the action of downward pressure, making the connection between the horizontal keel and the vertical keel more stable and reliable.

[0013] To enhance the sound insulation, an I-shaped sound insulation strip is installed within the vertical and horizontal keels, or at least within the vertical keel. The I-shaped strip has a drum-shaped protrusion at its waist, which elastically compresses against the inner wall of the I-shaped waist of the vertical and horizontal keels, preventing the strip from easily shifting after installation. Furthermore, the inner surface of the I-shaped strip features anti-sticking protrusions to reduce friction when inserted into the vertical and horizontal keels. This reduces the contact surface between the I-shaped strip and the inner wall of the I-shaped strip, ensuring smooth insertion. The addition of the I-shaped strip enhances sound insulation and is suitable for use in rooms in public areas.

[0014] After the wall of the keel frame is installed, it can be matched with the window frame profile. A window frame structure is fixedly set on the vertical keel, and window glass is installed on the window frame structure. The window frame structure consists of a clamping piece, an intermediate piece and a glass pressing piece. The clamping piece has a U-shaped cross section and is clamped in the I-shaped groove of the vertical keel. The cross section of the intermediate piece has a "J" structure to fit the I-shaped structure of the vertical keel. A clamping piece is set in the middle of the intermediate piece to extend into the clamping piece and fit with the inner wall of the clamping piece. An anti-slip protrusion and an anti-slip groove are set at the joint of the clamping piece and the clamping piece. The glass pressing piece is clamped at the end of the intermediate piece. The window glass is pressed between the step of the "J" structure of the intermediate piece and the glass pressing piece. A glass shock-absorbing rubber strip is set at the joint with the window glass.

[0015] To achieve height adjustment of the keel frame, further features are provided: The lower end of the vertical keel is connected to an adjustable foot that supports the keel frame structure and allows for height adjustment. The adjustable foot consists of a conical base, a ground angle adjustment screw, a fixing nut, a U-shaped insert support plate, and a rivet nut. The lower end of the ground angle adjustment screw extends into the conical base and is secured to the conical base via two fixing nuts disposed on either side of the conical base. The rivet nut is secured to the U-shaped insert support plate and threadedly connected to the ground angle adjustment screw. The U-shaped insert support plate is butt-jointed with the lower end of the vertical keel. The hollow structure of the vertical keel allows the U-shaped insert support plate to be quickly and easily docked with the vertical keel. The U-shaped insert support plate is butt-jointed with the lower end of the vertical keel and has an adjustment hole for the foot at the lower end of the vertical keel. The upper end of the ground angle adjustment screw is set to a four-cornered or hexagonal polygonal structure, and a wrench is inserted into the ground angle adjustment hole and screwed onto the ground angle adjustment screw, so that the rivet nut is displaced on the ground angle adjustment screw, thereby adjusting the installation height of the U-shaped plug-in bracket on the ground angle adjustment screw, thereby achieving height adjustment of the entire keel frame, thereby avoiding the influence of uneven ground on the installation of the keel frame.

[0016] In addition, if the keel frame has corners, a positive corner piece is set on the outside of the corner of the frame structure. The positive corner piece is clamped with the two vertical keels adjacent to the corner, thus ensuring the flatness of the entire wall and improving the aesthetics.

[0017] Compared with the existing technology, the benefits of the present invention are: the multifunctional assembled cold-bent light steel keel materials are all made of light steel cold rolling technology, which realizes the assembled installation of the keel, and realizes the assembled installation form of mortise and tenon connection or installation with fewer auxiliary screws. No welding is required on the construction site, avoiding the material deformation of the square tube keel caused by welding and the environmental impact of on-site corrosion, and also avoiding the defects of the traditional light steel keel connected by nails and rivets that cannot be disassembled and reused. The special I-shaped structure design strength is superior to the traditional square tube keel and the traditional light steel keel, greatly improving the surface flatness of the keel, and realizing the recycling of materials. It can be disassembled and assembled at any time according to needs, saving construction materials, simplifying the construction process, greatly shortening the installation time, greatly improving the installation efficiency and saving a lot of labor costs, laying a solid foundation for the better development of the assembly type (building industrialization) of construction projects.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] A multifunctional assembled cold-formed light steel keel frame wall structure, such as Figure 1 As shown, it is a frame structure composed of horizontal keels 1 and vertical keels 2 arranged in a longitude and latitude manner. The lower end of the vertical keel 2 is connected to an adjustable foot 28 for supporting the keel frame structure and allowing height adjustment. Figure 12 、 Figure 14 As shown, the adjustable foot 28 consists of a conical base 28-1, a ground angle adjustment screw 28-2, a fixing nut 28-3, a U-shaped insert support plate 28-4, and a rivet nut 28-5. The lower end of the ground angle adjustment screw 28-2 extends into the conical base 28-1 and is fixed to the conical base 28-1 by two fixing nuts 28-3 provided on both sides of the conical base 28-1. The rivet nut 28-5 is fixed to the U-shaped insert support plate 28-4 and is threadedly connected to the ground angle adjustment screw 28-2. The U-shaped insert support plate 28-4 is butt-jointed with the lower end of the vertical keel 2 and has a foot adjustment hole 29 at the lower end of the vertical keel 2. In addition, if the frame structure has a corner, a male corner piece 30 is provided on the outside of the corner to clamp the two adjacent vertical keels 2 at the corner.

[0042] like Figure 2 As shown, the cross section of the horizontal keel 1 is an I-shaped structure. The cross section of the vertical keel 2 can be of two types: Figure 3 、 Figure 4 As shown, the cross section of the vertical keel 2 is based on the I-shaped structure and two ear-shaped functional protrusions 3 are added to the upper and lower surfaces of the I-shaped structure, that is, a vertical keel 2 with a single functional protrusion; the cross section structure is shown in FIG. Figure 5 、 Figure 6 As shown, the cross section of the vertical keel 2 is based on the I-shaped structure and has a single functional protrusion 3 on the upper and lower surfaces of the I-shaped structure, that is, a vertical keel 2 with a single functional protrusion.

[0043] In addition, in order to improve the sound insulation effect, an I-shaped sound insulation strip 22 is inserted into the vertical keel 2 and the horizontal keel 1, or at least in the vertical keel 2. The waist of the I-shaped sound insulation strip 22 is provided with a drum-shaped protrusion 22-1, and the drum-shaped protrusion 22-1 is elastically pressed against the inner wall of the I-shaped waist of the vertical keel 2 and the horizontal keel 1. The inner surface of the I-shaped sound insulation strip 22 is provided with an anti-sticking protrusion 22-2 for reducing friction resistance when inserted into the vertical keel and the horizontal keel. Figure 7 、 Figure 8 shown.

[0044] like Figure 10 、 Figure 11 、 Figure 12 As shown, the horizontal keel 1 and the vertical keel 2 are detachable connection structures, and the two end pipe openings of the horizontal keel 1 are provided with connecting angle pieces 4, as shown in FIG. Figure 9 As shown, the connecting angle piece 4 includes an integrally formed plug-in portion 4-1, an extension portion 4-2, and a hanging portion 4-3 formed by folding the extension portion 4-2 outward. The plug-in portion 4-1 is inserted into the pipe opening of the horizontal keel 1 and clamped with the horizontal keel 1. The extension portion 4-2 extends into the I-shaped groove of the vertical keel 2. A keel hanging hole 5 is opened on the side wall of the I-shaped groove. Figure 4 、 Figure 6 As shown, the keel hanging hole 5 is composed of a top-wide and bottom-narrow flip guide hole 5-1 and a bottom-long narrow hanging slot 5-2. The hanging portion 4-3 falls into the keel hanging hole 5 to realize the hanging connection between the horizontal keel 1 and the vertical keel 2.

[0045] An inorganic panel 6 is installed between two adjacent vertical keels 2. The inorganic panel 6 is usually made of gypsum board. The outer edge side wall of the inorganic panel 6 fits the side wall of the functional protrusion 3 to achieve the positioning of the installation position and is fixed to the vertical keel 2 by fixing screws 7; an inorganic filler 8 is filled between the inorganic panels 6, and the specific inorganic filler 8 can be rock wool, and a decorative layer is provided on the outside of the inorganic panel 6.

[0046] Example 1: Figure 13 、 Figure 14 、 Figure 15As shown, the decorative layer consists of a portable hanging wall panel 9. Wall panel hooks 10 are located on both sides of the portable hanging wall panel 9. Wall panel hanging holes 11 are located on the top surface of the functional protrusions 3 of the vertical keel 2. The wall panel hooks 10 fall into the wall panel hanging holes 11, allowing the portable hanging wall panel 9 to be hung on the vertical keel 2. A rectangular sealing strip 12 is sandwiched between the functional protrusions 3, and its upper surface abuts the outer flange of the portable hanging wall panel 9. After the keel wall is installed, the keel hanging holes 5 on the vertical keel 2 can perfectly match the finished modular portable hanging wall panel 9, allowing the hanging panels to be installed simultaneously after the keel frame is erected, without the need for secondary waiting or measuring. Furthermore, the gaps between the portable hanging wall panels 9 can be handled in the following ways: 1. Treat the gaps; 2. Leave a 3mm gap untreated; 3. Fit tightly together; 4. Apply glue; 4. Insert a rubber strip. You can choose the right solution based on your current environment.

[0047] Example 2: Figure 16 、 Figure 17 As shown, the decorative layer is a mounting panel 13, which can be made of inorganic pre-coated board, glass, resin board, marble, etc. A panel transverse hook 14 is fixedly mounted on the inner surface of the mounting panel 13, and a panel transverse mounting seat 15 is fixedly mounted on the corresponding position on the outer surface of the inorganic panel 6. The panel transverse mounting seat 15 falls into the panel transverse hook 14 to mount the mounting panel 13 on the inorganic panel 6. A shock-absorbing pad 16 is provided next to the panel transverse mounting seat 15, which abuts against the inner surface of the mounting panel 13.

[0048] Example 3: Figure 18 As shown, the decorative layer is a veneer decorative panel 17, which is directly attached to the inorganic panel 6 using adhesive. After the keel wall is installed, the entire wall surface does not require secondary treatment and can be directly applied with universal glue, inorganic pre-coated panels, and resin panels. Because the keel is stronger than ordinary square tube keels, the surface flatness is well guaranteed.

[0049] Example 4: Figure 19 As shown, the decorative layer is a paint layer 18, and a filling putty 19 is filled between the functional protrusions 3. The surface of the filling putty 19 is flush with the surface of the inorganic panel 6. A bandage 20 is bonded to the surface of the filling putty 19. The surface of the inorganic panel 6 and the bandage 20 is a smoothed putty layer 21, and the paint layer 18 is sprayed on the surface of the putty layer 21. After the keel wall is installed, the grooves of the functional protrusions 3 of the vertical keel 2 are puttyed and smoothed, and the bandage 20 is applied to prevent cracking. The finished surface is completely ready for direct painting.

[0050] After the keel wall is installed, it can be combined with the window frame profile to form a glass partition. Due to the high strength of the keel, the overall glass partition is more stable than the glass partition installed in the conventional market.

[0051] Example 5: Figure 20 、 Figure 21 As shown, a window frame structure 23 is fixedly provided on the vertical keel 2, and a window glass 24 is installed on the window frame structure; the window frame structure is composed of a clamping piece 23-1, an intermediate piece 23-2 and a glass pressing piece 23-3. The clamping piece 23-1 has a U-shaped cross section and is clamped in the I-shaped groove of the vertical keel 2. The cross section of the intermediate piece 23-2 has a "F" structure to fit the I-shaped structure of the vertical keel 2. A clamping piece is provided in the middle of the intermediate piece 23-2 to extend into the clamping piece. 23-1 and a pressing piece 23-2-1 that fits with the inner wall of the pressing piece 23-1, an anti-slip protrusion 25 and an anti-slip groove 26 are provided at the joint of the pressing piece 23-2-1 and the pressing piece 23-1, a glass pressing piece 23-3 is clamped at the end of the middle piece 23-2, and the window glass 24 is pressed between the step of the "X" structure of the middle piece 23-2 and the glass pressing piece 23-3, and a glass shock-absorbing rubber strip 27 is provided at the joint with the window glass 24.

[0052] In the above-mentioned embodiments, the structural diagrams are all based on the example of two functional protrusions 3 on the same side of the vertical keel 2. Of course, the vertical keel 2 in the above-mentioned embodiments can also adopt the structure of a single functional protrusion 3, which has a simpler manufacturing process and is more practical. It is suitable for situations where no sealing strip is required to be installed in the middle. For example, this structure can be adopted in embodiments 2 to 5. Of course, in embodiment 1, if the sealing requirements are not high, the rectangular sealing strip 12 is not installed, and a single functional protrusion 3 structure can also be adopted. In addition, in embodiment 4, the filling process of the double-eared functional protrusion 3 requiring filling with putty 19 can also be omitted, which is more convenient and quick.

[0053] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
