Description

Technical Field

[0001] This invention belongs to the field of interior decoration engineering, and in particular to a multifunctional open-type combined keel, an application wall system and its construction method. Background Technology

[0002] The keel is a key component of the decorative base layer, serving as the supporting framework for the decorative surface. Interior decoration projects are typically complex, and to ensure the final decorative effect, different keel systems are selected for construction and design depending on the usage environment and surface materials. Various types of cold-formed thin-walled steel keels are available on the market, each with multiple functions, such as for panel hanging, panel flat insertion, side-insertion panel connection, and base panel nailing. However, their functions are relatively limited and not well-integrated with other base layer keel systems.

[0003] For example, some keels are specifically designed for panel hanging installations. Their structural features provide a relatively stable connection when suspending decorative panels. While their structure is conducive to panel connection, they are difficult to apply when performing panel flat-insertion or side-insertion splicing. Other keels focus on panel flat-insertion functionality, enabling flat splicing between adjacent panels, but they cannot meet the strength and structural requirements for nailing installation of the baseboard. Still other keels are only suitable for side-insertion installation of panels and are not applicable when panel hanging or other types of decorative processes are required.

[0004] While different types of keel have their advantages in their specific applications, their limited functionality often necessitates the stocking of multiple types in comprehensive decoration projects. This not only increases material procurement and storage costs but also complicates material management at the construction site. Furthermore, frequent switching between different types of keels during actual construction inevitably prolongs the project timeline, as the installation methods and connection details vary, requiring workers to spend extra time familiarizing themselves with and adapting to different construction techniques.

[0005] Meanwhile, during installation, traditional partition wall keel systems typically fix the vertical keel to the top and bottom keels with nails, or with supports and inserts. While nailing is simple and direct, it is prone to loosening over time, and the nail holes damage the keel's anti-rust coating, making it susceptible to corrosion and quality issues later on. Furthermore, the structural state of the keel is altered by nailing, making it difficult to reuse. The support and insert fixing method also has some drawbacks. Inserts can usually only be inserted from top to bottom or bottom to top, making it difficult to operate when the installation height is insufficient. The inserts are not connected to the keel with fasteners, leaving them free to move, and there is a certain gap between the insert and the inner wall of the keel cavity, causing the keel to vibrate under external forces. Some inserts also have complex structures and high manufacturing costs. Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional open-type combined keel and wall system and its installation method. This addresses the problems of existing cold-formed thin-walled steel keels having limited functionality and poor compatibility between different keels, leading to high material costs, long construction periods, complex construction, and negative impacts on decorative effects and structural stability during prefabricated decoration. It also solves problems with existing keel installation methods in partition wall systems, such as nailing which is prone to loosening and corrosion, screws which can damage the keel structure and hinder secondary recycling; and plug-in support installation which can only be inserted from the end of the keel, leaving gaps between the plug and the keel without proper fixation, resulting in vibration under external forces.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multifunctional open-type composite keel, comprising:

[0009] The column keel has an arched opening structure in cross-section, including a one-piece central convex groove and symmetrically arranged side grooves on both sides.

[0010] The central groove includes a central groove protrusion plate and an inner side plate. The central groove protrusion plate has keel fixing holes arranged in rows along the length direction to connect the column keel to other load-bearing components.

[0011] The side groove and the central convex groove share an inner side plate, including an inner side plate, a bottom plate of the side groove, and an outer side plate. The three side plates of the side groove are all provided with keel external connection holes arranged in rows along the length direction to connect other external components to the column keel. The ends of the outer side plate are bent inward to form a side plate that maintains an installation distance from the central groove convex plate.

[0012] The keel external connection holes include external mounting holes on the side groove bottom plate and the outer side plate, as well as internal snap-fit ​​holes on the inner side plate. The cavity of the central convex groove forms a snap-fit ​​installation cavity.

[0013] Other external components include:

[0014] External attachments include corner brackets that are anchored to the panel, and external attachments with hooks that connect to external mounting holes.

[0015] The flat-insertion assembly includes a female component and a female component.

It includes a flat plate that is tightly attached to the inner wall of the central groove protrusion plate, corner plates that are connected to both ends of the flat plate and snap into internal snap holes on both sides, and limiting hooks connected to the corner plates. A channel for inserting the female component is left between the two limiting hooks. The female component includes a parallel leg that is anchored to the panel and a female component insert plate that is vertically inserted into the female component insert channel. The head of the female component insert plate has a snap protrusion, and the connection between the snap protrusion and the recess of the female component insert plate is limited by the end protrusion of the limiting hook.

[0016] The side-insertion unit includes a connecting leg that is inserted into the snap-fit ​​mounting cavity. The connecting leg bolt hole on the connecting leg is anchored to the keel fixing hole of the central groove protrusion plate by a flat-insertion bolt. It also includes a side-insertion main plate perpendicular to the connecting leg. The end of the side-insertion main plate is divided into two side-insertion sub-plates facing the left and right sides. The side-insertion sub-plates are inserted into the side slots reserved on one side end face of the panel.

[0017] Other load-bearing components include:

[0018] The extended insert keel is set between the ends of the column keel and is integrally formed to fit the inner wall of the cavity of the side groove and the outer contour of the central groove protrusion. It includes an insert roll plate built into the side groove and an insert connecting plate that connects the two insert roll plates laterally. The insert connecting plate is located on the outside of the central groove protrusion. The insert connecting plate forms an adaptive indentation at the side plate position. The insert connecting plate is provided with two vertical insert elongated oval holes. Each insert elongated oval hole corresponds to the keel fixing hole at the end of one side of the column keel and is anchored by an extension bolt.

The four snap-fit ​​holes in two adjacent groups correspond to the four base snap-fit ​​rolled edges of one base plate. The base plate has insertion holes and base connection holes that correspond to the component bolt holes and are anchored by structural bolts.

[0023] The C-type insert plate has insert plate connection holes on its web. The bottom center of the C-type insert plate web and / or insert plate side plate has a downwardly bent, outwardly rolled edge tongue that mates with the insertion hole.

[0024] The column keel is inserted into the U-shaped groove of the horizontal keel. The opening direction of the C-shaped insert plate corresponds to the opening direction of the side groove. The central convex groove is inserted into the C-shaped insert plate. The insert plate side plate is inserted into the side groove on both sides along the outer wall of the inner side plate. The insert plate connecting hole is aligned with the keel fixing hole and anchored by the column bolt.

[0025] There are two types of bolt holes for the components:

[0026] Single hole, structural bolts are directly passed through the single hole and anchored to the base connection hole;

[0027] Double hole, with a central hole and sliding holes on both sides; structural bolts slide from the central hole to the sliding holes on both sides and then pass through the base connection hole for anchoring;

[0028] The base plate comes in two forms:

The connecting ear plates are set along the length of the horizontal keel. The base connecting holes are set at the ends of the connecting ear plates. The connection between the base plate and the connecting ear plates is bent inwards downwards. The connecting ear plates have base connecting holes. The outward bending height of the rolled edge of the base plate relative to the base plate is greater than the inward bending height of the connecting ear plate relative to the base plate. At the same time, the inward bending height of the connecting ear plate relative to the base plate is not less than the thickness of the outwardly rolled edge tongue.

[0031] There are three types of interlocking fixing components between keels:

[0032] In a single-row configuration, each keel has an interlocking fixing component consisting of a row of C-shaped inserts. The opening of the C-shaped insert faces the length of the horizontal keel. The connection method includes a single plate with double holes or double ear plates with a single hole, corresponding to a horizontal column keel.

The L-shaped corner brackets are anchored to the original structure and the column keels. Each of the two legs of the L-shaped corner bracket has an adjustable elongated hole. The L-shaped corner bracket includes parallel legs and vertical legs.

[0036] When the opening of the side groove is parallel to the original structure, a wall L-shaped bracket is installed. The parallel leg of the bracket is parallel to the original structure and is anchored by structural bolts. The vertical leg of the bracket is anchored to the central groove protrusion plate by wall keel bolts. The back of the panel is connected to the external mounting hole of the column keel by external brackets.

[0112] See Figure 10-12 As shown, the horizontal keel 8 has a U-shaped cross-section and includes an integrally formed bottom web plate 81 and side panels 82. The bottom web plate 81 is concave upwards relative to the side panels 82, and the connection point is curled to form an arc-shaped leg 83. A hidden receiving cavity 84 is formed between the bottom web plate 81 and the arc-shaped legs 83 on both sides. The bottom web plate 81 has component connection holes with a fixed module along its length. The component connection holes include snap-fit ​​holes 85 and component bolt holes 86. The snap-fit ​​holes 85 and component bolt holes 86 are alternately arranged. The snap-fit ​​holes 85 are rectangular holes arranged in groups symmetrically on both sides. The component bolt holes 86 are arranged in a row along the length of the horizontal keel 8, with a component bolt hole 86 located in the center between two adjacent groups of snap-fit ​​holes 85. The hidden receiving cavity 84 can be used to insert vibration damping rubber pads and further conceal bolt heads.

[0113] See Figure 13-16 As shown, the interlocking fixing assembly 9 between the keels includes a C-shaped insert plate 91 and a base plate 92.

[0114] The base plate 92 has symmetrically arranged downwardly protruding and bent edges at its four corners, which mate with the snap-fit ​​holes 85. The four snap-fit ​​holes 85 in two adjacent groups correspond to the four snap-fit ​​edges 921 of one base plate 92. The snap-fit ​​edges 921 mate with the snap-fit ​​holes 85 of the horizontal keel 8, serving to position and limit movement.

[0115] The base plate 92 has a plug hole 922 and a base connection hole 925 that corresponds to the component bolt hole 86 and is anchored by the structural bolt 40. The insert plate web 911 of the C-shaped insert plate 91 has an insert plate connection hole 914, which is a vertical elongated hole. The bottom center of the insert plate web 911 and / or insert plate side plate 912 of the C-shaped insert plate 91 is provided with a downwardly bent, outwardly rolled edge tongue 913 that mates with the plug hole 922. The outwardly rolled edge tongue 913 mates with the plug hole 922 and is connected as a whole by a snap-fit ​​and pressing method.

[0116] See Figure 17-26 As shown, the column keel 1 is inserted into the U-shaped groove of the horizontal keel 8. The opening direction of the C-shaped insert plate 91 corresponds to the opening direction of the side groove. The central convex groove 11 is inserted into the C-shaped insert plate 91. The insert plate side plate 912 of the C-shaped insert plate 91 is inserted into the side grooves 12 on both sides along the outer wall of the inner side plate 112. The insert plate connecting hole 914 is aligned with the keel fixing hole 14 and anchored by the column bolt 18. The relative position of the column keel 1 and the C-shaped insert plate 91 is adjusted according to the corresponding position of the insert plate connecting hole 914 and the keel fixing hole 14.

[0117] See Figure 11-12 As shown, the component bolt holes 86 include two types:

[0118] The single hole 86a is anchored to the base by directly passing through the single hole and connecting to the base hole 925 with the structural bolt 40.

[0119] Double hole 86b, central hole 861 with double slide hole 862 on both sides; structural bolt 40 slides from central hole 861 to slide hole 862 on both sides and then passes through base connection hole 925 for anchoring.

[0120] See Figure 13-16 As shown, the base plate 92 includes two types:

[0121] The single board 92a has a base connection hole 925 located on the outside of the C-shaped insert 91.

[0122] The base plate 92 has two ear plates 92b. Symmetrical connecting ear plates 923 extend integrally from the middle of the base plate 92 to both sides between the base plate 92 and the rolled edge 921. The connecting ear plates 923 are arranged along the length of the horizontal keel 8. Base connecting holes 925 are located at the ends of the connecting ear plates 923. The connection between the base plate 92 and the connecting ear plates 923 is bent inwards at a downward angle 924. The connecting ear plates 923 have base connecting holes 925. The outward bending height of the rolled edge 921 relative to the base plate 92 is greater than the inward bending height of the connecting ear plate 923 relative to the base plate 92. Simultaneously, the inward bending height of the connecting ear plate 923 relative to the base plate 92 is not less than the thickness of the outwardly rolled edge tongue 913. This bending and height design allows the connecting ear plates 923 and the bottom web plate 81 to fit completely together when the rolled edge 921 is inserted into the locking hole 85.

[0123] The interlocking fixing assembly 9 between the keels includes three types:

[0124] See Figure 13-14 As shown in 17-20, in the single-row 9a, each keel interlocking fixing component 9 includes a row of one C-shaped insert plate 91. The opening of the C-shaped insert plate 91 faces the length direction of the horizontal keel 8. The installation position of the C-shaped insert plate 91 is such that the vertical center axis of the keel after the column keel 1 and the C-shaped insert plate 91 are installed coincides with the center of the base plate 92. The connection method includes a single plate 92a with double holes 86b or double ear plates 92b with single holes 86a, corresponding to a horizontal column keel 1.

[0125] See Figure 15 , 17 As shown in Figures 21-23, in parallel configuration 9b, each keel interlocking fixing component 9 includes a row of two C-shaped insert plate groups. The openings of the C-shaped insert plates 91 are arranged opposite each other with their openings facing outwards along the length of the horizontal keel 8. The insert plate webs 911 of the two C-shaped insert plates 91 are attached to each other. The vertical central axis of the C-shaped insert plate group coincides with the center of the base plate 92. The connection method is that the double ear plate 92b cooperates with the single hole 86a, corresponding to two horizontally facing column keels 1.

[0126] See Figure 16 , 17 As shown in Figures 24-26, the double-row 9c has two rows of C-shaped insert plate groups 9 connected between each keel. The openings of the C-shaped insert plates 91 are arranged opposite each other with their openings facing outwards, along the width direction of the horizontal keel 8. The edges of the insert plate side plates 912 of the two C-shaped insert plates 91 are flush with the edges of the base plate 92. The vertical central axis of the C-shaped insert plate group coincides with the center of the base plate 92. The connection method is that the double ear plates 92b are matched with the single hole 86a, corresponding to two longitudinally facing column keels 1.
