Description

Technical Field

[0001] This utility model belongs to the field of interior decoration engineering, and in particular to an arch-shaped combined keel flat-insertion partition wall system. Background Technology

[0002] The keel is the main component of the decorative base layer, serving as the supporting framework for the decorative surface. Interior decorative partition wall projects are typically quite complex. To ensure the final decorative effect, different keel systems are selected for construction and design depending on the usage environment and surface materials. Compared to partition wall hanging systems, the side-insertion partition wall system allows for lateral side-insertion construction, supports standardized modular splicing, reduces manual leveling steps, and shortens the construction period.

[0003] Traditional plug-in components mostly use a single plug-in form and lack a two-way limiting structure, making them prone to loosening under vibration or temperature deformation, and posing a risk of hollowing after panel installation. At the same time, existing partition wall plug-in systems and their keels generally have insufficient structural stability. The column keel uses a single groove structure, resulting in excessive stress concentration at the plug-in connection point and insufficient moment of inertia, which easily leads to lateral bending during installation. The plug-in components need to be connected to the column keel with connectors, which compromises the original cross-sectional integrity of the column keel.

[0004] Meanwhile, various types of cold-formed thin-walled steel keels are available on the market, each with multiple functions. For example, custom-made keels are required between partition wall flush-insertion systems, and special hangers are needed for external systems. It is impossible to use the same set of keels to be compatible with two different installation systems. This limited functionality necessitates the stocking of multiple types of keels in comprehensive decoration projects, significantly increasing material procurement costs, warehousing costs, and construction time.

[0005] Traditionally, the installation of vertical and horizontal keels mainly involves two methods: nailing and bracket insertion. While nailing is simple, it is prone to loosening over time, and the nail holes damage the keel's anti-rust coating, leading to corrosion, affecting quality, and damaging the keel structure, making it difficult to reuse. Bracket and bracket insertion methods typically only allow for unidirectional insertion, making operation difficult when the height is insufficient; the brackets are not fastened to the keel, allowing free movement, and there are gaps between the brackets and the inner wall of the keel cavity, making the keel prone to vibration under external forces; some bracket structures are complex and costly to manufacture. Utility Model Content

[0006] The purpose of this utility model is to provide an arc-shaped combined keel flat-insertion partition wall system, which aims to solve the problems of the single plug-in form of the flat-insertion components, which is prone to falling off and installation hazards, insufficient stability of the vertical main keel structure, excessive stress at the flat-insertion connection point that damages the integrity of the cross section, poor functional compatibility between different installation systems, and installation problems between the columns and horizontal keels.

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

[0008] A bow-shaped combined keel flat-insertion partition wall system includes column keels, flat-insertion components, and panels. The back of the panels is inserted into the column keels via the flat-insertion components.

[0009] The cross-section of the column keel has an arched opening structure, including an integrally formed central convex groove and symmetrically arranged side grooves on both sides. The cavity of the central convex groove forms a snap-fit ​​installation cavity. The central convex groove includes a central groove protrusion plate and an inner side plate. The inner side plate has internal snap-fit ​​holes arranged in rows along the length direction.

[0010] The flat insertion assembly includes a female component and a female component. The height of the female component is no greater than the height of the inner locking hole and it is embedded in the locking mounting cavity. The female component is a one-piece symmetrical butterfly structure with a gap in the middle forming a female component insertion channel. The female component is an irregular L-shaped component, including a female component parallel limb anchored to the panel and a female component insertion plate that is vertically inserted into the female component insertion channel. The head of the female component insertion plate is provided with a locking protrusion, and the connection between the locking protrusion and the recess of the female component insertion plate is limited by the end protrusion of the limiting hook.

[0011] The central groove protrusion plate has keel fixing holes arranged in rows along the length direction to connect the column keel with other load-bearing components. The side groove and the central protrusion share an inner side plate, including an inner side plate, a side groove bottom plate and an outer side plate. The side groove bottom plate and the outer side plate of the side groove both have external hanging holes arranged in rows along the length direction to hang other components.

[0012] The mother part 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 respectively inserted into the inner locking holes on both sides, a limiting hook connected to the corner plate, and a child part insertion channel left between the two limiting hooks.

[0013] It also includes two horizontal keels, a keel-to-keel fixing assembly connecting the column keel and the horizontal keel, and a panel support bracket that connects to the horizontal keel and supports the bottom of the panel.

[0014] The horizontal keel consists of a top keel and a bottom keel, which are connected to the ceiling and the ground respectively. The keel interlocking fixing components are adapted to the module of the column keel and are connected between the column keel and the horizontal keel. The panel support bracket is on the horizontal keel, and the bottom of the panel rests on the panel support bracket.

[0015] The horizontal keel has a U-shaped cross-section and includes an integrally formed bottom web and side panels.

[0016] The interlocking fixing assembly between keels includes a C-shaped insert plate and a base plate that are connected in combination. The C-shaped insert plate is inserted into the base plate. The interlocking fixing assembly between keels is of the double-row type, with each keel interlocking fixing assembly including two rows of one C-shaped insert plate group. The openings of the C-shaped insert plates are all oriented along the width direction of the horizontal keel, with the openings facing outwards and backing each other. The edges of the insert plates of the two C-shaped insert plates are flush with the edges of the base plate.

[0017] 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 of the C-shaped insert plate is inserted into the side grooves on both sides along the outer wall of the inner side plate.

[0018] The bottom web plate has component connection holes with a fixed module along its length. The component connection holes include intermittently spaced snap-fit ​​holes and component bolt holes.

[0019] The snap-fit ​​holes are arranged symmetrically in groups, with a component bolt hole centered between two adjacent groups. The four snap-fit ​​holes in two adjacent groups correspond to the four base snap-fit ​​rolled edges of a base plate.

[0020] There are two types of bolt holes for the components:

[0021] Single hole, structural bolts are directly passed through the single hole and anchored to the base connection hole;

[0022] 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;

[0023] The bottom web plate is concave upwards and inwards on opposite side plates, and the connection point is curled to form an arc-shaped leg. A hidden receiving cavity is formed between the bottom web plate and the arc-shaped legs on both sides.

[0024] The base plate has symmetrically arranged downward-protruding rolled edges at the four corners, which mate with the locking holes. The base plate has insertion holes. Symmetrical connecting ear plates extend integrally from the middle of the base plate to both sides between the base locking rolled edges and the middle of the base plate. The connecting ear plates are arranged along the length of the horizontal keel, and the base connecting holes are located at the ends of the connecting ear plates. The connection between the base plate and the connecting ear plates is bent downward-inward. The outward bending height of the base locking rolled edge 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 outward-rolling pressing edge tongue.

[0025] 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 is provided with a downwardly bent, outwardly rolled edge tongue that mates with the insertion hole. The connecting ear plate is set along the length of the horizontal keel. The base connection hole is aligned with the corresponding component bolt hole and anchored by structural bolts. The insert plate connection hole is aligned with the keel fixing hole and anchored by column bolts.

[0026] The panel support bracket includes a hanging part that conforms to the contour of the side panel edge, the outer end of the hanging part forming a support groove, and a horizontal connecting part provided on the hanging part.

[0027] The panel support bracket includes double-sided brackets and single-sided brackets. The double-sided brackets span the horizontal keel and include two hanging parts. The horizontal connecting part is a single plate connecting the two hanging parts. The single-sided bracket includes one hanging part. The horizontal connecting part is a bracket ear plate. The bracket ear plate has bracket snap-fit ​​rolled edges with downward outward bending on both sides that cooperate with the snap-fit ​​holes. The bracket bolt holes at the front end of the bracket ear plate are anchored to the component bolt holes by bracket bolts.

[0028] Compared with the prior art, this utility model has the following features and beneficial effects:

[0029] This utility model designs an arc-shaped combined keel flat-insertion partition wall system. It employs an integrally molded arc-shaped open structure column keel, with the central convex groove of the arc-shaped cross-section forming the longitudinal load-bearing core, and the side grooves providing lateral bending resistance. The continuous bending structure of the inner and outer side panels forms a closed stress ring, effectively distributing the load and improving overall stability. The symmetrical corner plates of the mother component engage with the inner locking holes to form bidirectional constraints, and the cooperation of the limiting hooks and locking protrusions achieves three-dimensional limiting, avoiding the risk of loosening associated with traditional single-point insertion and ensuring long-term stable connection of the panels.

[0030] The inner locking hole in the keel external connection hole of this utility model, which cooperates with the designed flat insertion component, realizes the connection of the flat insertion partition system. The external connection hole, which cooperates with the external bracket, realizes the connection of the external partition system. The flat insertion system can be installed alone or in combination with the external bracket system, reducing the types and quantities of materials purchased and lowering procurement costs; reducing the storage space requirement and reducing storage costs; improving construction efficiency; avoiding the downtime caused by frequent keel switching during construction; and shortening the construction period.

[0031] This utility model also includes a horizontal keel, a keel-to-keel interlocking fixing component, and a panel support bracket designed to match the column keel. This allows it to be used in partition wall flat-insertion systems, with the entire process connected by bolts, eliminating the need for nail installation. This method is more stable than using screws on light steel keels and allows for secondary recycling. The open-type installation process allows the insert to be inserted from the side, solving the problem of difficulty in inserting from the end of the keel when the height is insufficient. It also solves the problem of vibration caused by gaps between the insert and the keel under external forces. The insert structure is simple and inexpensive to manufacture, overcoming many drawbacks of existing partition wall keel installation methods and enabling the conversion and combination of the same keel between different partition wall systems.

The cavity of the central convex groove 11 forms a locking mounting cavity 13.

[0064] See Figure 1-2 As shown in Figures 4-6, the flat insertion assembly 2 includes a female component 21 and a female component 22. The height of the female component 21 is no greater than the height of the inner locking hole 162 and it is embedded in the locking mounting cavity 13.

The female component 21 includes a flat plate 211 that is close to the inner wall of the central groove protrusion plate 111, corner plates 212 that are connected to both ends of the flat plate 211 and respectively inserted into the inner locking hole 162 on both sides, and a limiting hook 213 connected to the corner plate 212. The female component insertion channel 214 is left between the two limiting hooks 213. See Figure 4 As shown, each sub-sub ...

[0065] See Example 2 Figure 2-3 As shown in Figure 5, unlike Embodiment 1, each sub-part insertion channel 214 is provided with two sub-parts 22 arranged symmetrically opposite to each other.

[0066] See Figure 9 and Figure 17As shown, the bow-shaped combined keel flat-insertion partition wall system also includes two horizontal keels 3, a keel interlocking fixing component 4, and a panel support bracket 8. The horizontal keels 3 are the top keel and the bottom keel, respectively, and are connected to the ceiling and the ground. The keel interlocking fixing component 4 is adapted to the module of the column keel 1 and is connected between the column keel 1 and the horizontal keel 3. The panel support bracket 8 is on the horizontal keel 3, and the bottom of the panel 5 rests on the panel support bracket 8.

[0067] See Figure 10 As shown, the horizontal keel 3 has a U-shaped cross-section and includes an integrally formed bottom web plate 31 and side panels 32. (See also...) Figure 13-14 As shown, the inter-keel insertion fixing assembly 4 includes a combined C-shaped insert plate 41 and a base plate 42. The C-shaped insert plate 41 is inserted into the base plate 42. The inter-keel insertion fixing assembly 4 is a double-row type, with each inter-keel insertion fixing assembly 4 including two rows of C-shaped insert plates. The openings of the C-shaped insert plates 41 are all oriented along the width direction of the horizontal keel 3, with the openings facing outwards and backing each other. The edges of the insert plate side plates 412 of the two C-shaped insert plates 41 are flush with the edges of the base plate 42. The vertical central axis of the C-shaped insert plate assembly coincides with the center of the base plate 92.

[0068] See Figure 15-17 As shown, the column keel 1 is inserted into the U-shaped groove of the horizontal keel 3, the opening direction of the C-shaped insert plate 41 corresponds to the opening direction of the side groove 12, the central convex groove 11 is inserted into the C-shaped insert plate 41, and the insert plate side plate 412 of the C-shaped insert plate 41 is inserted into the side groove 12 on both sides along the outer wall of the inner side plate 112.

[0069] In this embodiment, the bottom web plate 31 is provided with component connection holes with a fixed module along its length. The component connection holes include snap-fit ​​holes 35 and component bolt holes 36 arranged alternately at intervals. The snap-fit ​​holes 35 are rectangular holes arranged in groups symmetrically arranged from left to right, and a component bolt hole 36 is provided in the center between two adjacent groups of snap-fit ​​holes 35.

[0070] The component bolt holes 36 include two types:

[0071] See Figure 11 As shown, in single hole 36a, structural bolt 6 passes directly through the single hole and is anchored to the base connection hole 425.

[0072] See Figure 12 As shown, there is a double hole 36b and a central hole 361 with double sliding holes 362 on both sides; the structural bolt 6 slides from the central hole 361 to the double sliding holes 362 on both sides and then passes through the base connection hole 425 for anchoring.

[0073] See Figure 10As shown, the bottom web plate 31 is concave upwards and inwards relative to the side plates 32, and the connection point is curled to form an arc-shaped leg 33. A hidden receiving cavity 34 is formed between the bottom web plate 31 and the arc-shaped legs 33 on both sides. The hidden receiving cavity 34 can be used to insert vibration-damping rubber pads and further conceal bolt heads.

[0074] See Figure 13-14 As shown, the four corners of the base plate 42 are symmetrically provided with downwardly convex and outwardly bent base snap-fit ​​rolled edges 421 that mate with snap-fit ​​holes 35. The base plate 42 has insertion holes 422. Symmetrical connecting ear plates 423 extend integrally from the middle of the base plate 42 to both sides between the base snap-fit ​​rolled edges 421.

The four snap-fit ​​holes 35 of two adjacent sets of the base plate correspond to the four base snap-fit ​​rolled edges 421 of one base plate 42. The base snap-fit ​​rolled edges 421 mate with the snap-fit ​​holes 35 of the horizontal keel 3, serving a positioning and limiting function. The height of the outward convex bend of the base snap-fit ​​rolled edge 421 relative to the base plate 42 is greater than the height of the inward concave bend 424 of the connecting ear plate 423 relative to the base plate 42, while the height of the inward concave bend 424 of the connecting ear plate 423 relative to the base plate 42 is not less than the thickness of the outwardly rolled edge tongue 413.

[0075] See Figure 9 , Figure 13-17 As shown, the C-shaped insert plate 41 has an insert plate connection hole 414 on its insert plate web 411.

The bottom center of the C-shaped insert plate 411 and / or the insert plate side plate 412 is provided with a downwardly bent, outwardly rolled edge tongue 413 that mates with the insertion hole 422. The outwardly rolled edge tongue 413 mates with the insertion hole 422, and the insert plates are connected as one unit by a snap-fit ​​and pressing method. The connecting ear plate 423 is set along the length of the horizontal keel 3. The base connecting hole 425 is aligned with the corresponding component bolt hole 36 and anchored by the structural bolt 6. The insert plate connection hole 414 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 41 is adjusted by the corresponding insertion plate connection hole 414 and keel fixing hole 14.

[0076] See Figure 18-20As shown, the panel support bracket 8 includes a hanging part 81 that conforms to the edge contour of the side panel 32. The outer end of the hanging part 81 forms a support groove 82, and the hanging part 81 is provided with a horizontal connecting part. The panel support bracket 8 includes a double-sided bracket 83 and a single-sided bracket 84. The double-sided bracket 83 spans the horizontal keel 3 and includes two hanging parts 81. The horizontal connecting part is a single plate 85 that connects the two hanging parts. The single-sided bracket 84 includes one hanging part 81. The horizontal connecting part is a bracket ear plate 86. The bracket ear plate 86 has bracket snap-fit ​​rolled edges 87 that are bent outwards and mate with the snap-fit ​​holes 35 on both sides. The bracket bolt hole 88 at the front end of the bracket ear plate 86 is anchored to the component bolt hole 36 by bracket bolts.

[0077] The installation method and construction steps for this bow-shaped combined keel flat-insertion partition wall system are as follows:

[0078] Step 1: Perform measurement and layout, accurately locate the positions of each installation component and panel 5, and select the double-row interlocking fixing component 9 between the keels;

[0079] Step 2: Set the horizontal keel 3 as the ceiling keel and the ground keel, and fix it to the ceiling and the ground by passing the structural bolts 6 through the component bolt holes 36. Fill the hidden receiving cavity 34 of the ground keel with vibration damping rubber pads.

[0080] Step 3: Connect the keel interlocking fixing component 4 to the top keel and the bottom keel respectively. Then, insert the column keel 1 into the C-shaped insert plate 41 from the front and / or rear sides respectively. Place vibration damping rubber pads between the C-shaped insert plate 41 and the column keel 1. Insert vibration damping rubber blocks 200 between the two C-shaped insert plates 41. Then, use column bolts 18 to fix the column keel 1, vibration damping rubber blocks 200 and C-shaped insert plates 41.

[0081] Step 4: Insert the mother part 21 into the snap-fit ​​mounting cavity 13 according to the module, then insert the panel support bracket 8 into the floor joist, and place the pad block 300 on the panel support bracket 8 to control the position of the control panel 5.

[0082] Step 5: Fix the sub-component 22 to the back of the panel 5 according to the module of the mother component 21, and then place the bottom of the panel 5 on the outside of the panel support bracket 8 and the pad 300. Insert the sub-component 22 flat into the corresponding mother component 21 to complete the installation.

[0083] Step 6: Install the protruding part of the skirting board cover panel support bracket 8 to complete the installation.

[0084] See Example 3 Figure 21As shown, unlike embodiments one and two, the partition wall system can be compatible in certain situations. For example, when two panels 5 are spliced, a flat plug component 2 can be fixedly connected to one side of the column keel 1, and an external hanger 7 can be fixedly connected to the other side of the column keel 1. The external hanger 7 is hung on the external hanging hole 161. The panels 5 on both sides are connected to the flat plug component 2 and the external hanger 7 respectively to form a flat plug hanging hybrid connection.
