Description

Technical Field

[0001] This utility model belongs to the field of interior decoration engineering, and in particular to a composite cross-section keel multi-directional connection external partition wall system. Background Technology

[0002] The keel is a key component of the decorative base layer, serving as the supporting framework for the decorative surface. Existing cladding systems and their keels generally suffer from the following technical defects:

[0003] Insufficient structural stability: The column keel adopts a single groove structure, which leads to excessive stress concentration at the connection point. The one-way opening results in insufficient bending stiffness and insufficient moment of inertia of the section, making it prone to lateral bending during installation.

[0004] Poor application compatibility: Different hanging systems cannot use the same set of keel for mutual compatibility, resulting in wasted materials and increased budget;

[0005] Installation is inconvenient: During installation, the column keel is usually fixed 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 anti-rust coating of the keel, making it susceptible to corrosion and quality problems later on. The damaged keel structure is also difficult to reuse. Supports and inserts also have 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 fastened to the keel, leaving them free to move, and there is a gap between the insert and the inner wall of the keel cavity, causing the keel to vibrate under external force. Some inserts also have complex structures and high manufacturing costs. Utility Model Content

[0006] The purpose of this invention is to provide a multi-directional connection external partition wall system with composite cross-section keel, which aims to solve problems such as insufficient stability of existing cold-formed thin-walled steel keel structures, poor compatibility between different directional connection systems, easy loosening and corrosion of keel during nail installation, damage to keel structure by screws, and difficulty in secondary recycling; plug-in support installation can only be inserted from the end of the keel, resulting in gaps between the plug and the keel without fixation, and vibration caused by external forces.

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

[0008] A composite cross-section keel multi-directional connection external partition wall system includes vertical keel, external brackets, upper and lower horizontal keels, interlocking fixing components between the keels, and a panel. The interlocking fixing components between the keels are adapted to the module of the vertical keel and are connected between the vertical keel and the horizontal keel.

[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 central convex 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 structures. The side grooves share an inner side plate with the central convex groove, including an inner side plate, a side groove bottom plate, and an outer side plate. The three side plates of the side groove all have keel external connection holes arranged in rows along the length direction to allow external brackets to be attached to the column keel. The ends of the outer side plates are bent inward to form side plates that maintain an installation distance from the central groove protrusion plate.

[0010] The external attachment is a corner piece, including a parallel leg of the corner piece anchored to the panel, and an external attachment leg perpendicular to the parallel leg of the corner piece. The external attachment leg is provided with a hook that hangs vertically downward to the external connection hole of the keel. The back of the panel is attached to the external connection hole of the keel through the external attachment.

[0011] The horizontal keel consists of a top keel and a bottom keel, which connect to the ceiling and floor respectively. The horizontal keel has a U-shaped cross-section and includes an integrally formed bottom web plate and side panels. The vertical keel is inserted into the U-shaped groove of the horizontal keel.

[0012] The bottom web plate has component connection holes with a fixed module along its length. The component connection holes include intermittently arranged snap-fit ​​holes and component bolt holes. The opposite side panels of the bottom web plate are concave upwards and inwards, and the connection is curled to form arc-shaped legs. A hidden receiving cavity is formed between the lower part of the bottom web plate and the arc-shaped legs on both sides.

[0013] The interlocking fixing assembly between keels includes a C-shaped insert plate and a base plate that are combined and connected. The C-shaped insert plate is inserted into the base plate. 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.

[0014] The base plate has symmetrically arranged downward-protruding and outward-bending base snap-fit ​​rolled edges at its four corners, which mate with the snap-fit ​​holes. The base plate also has insertion holes and base connection holes that correspond to the component bolt holes and are anchored by structural bolts.

[0015] 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.

[0016] The C-type insert plate has insert plate connection holes on its web. The bottom center of both the insert plate web and the insert plate side plate of the C-type insert plate has a downward-bent, outward-rolling pressing tongue that mates with the insertion hole. The insert plate connection hole is aligned with the keel fixing hole and is anchored by column bolts.

[0017] There are two types of bolt holes for the components:

[0018] Single hole, structural bolts are directly passed through the single hole and anchored to the base connection hole;

[0019] Double hole, with a central hole having 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.

[0020] The base plate comes in two forms:

[0021] The base connection holes of the single board are located on the outside of the C-shaped insert.

[0022] The base plate has two ear plates. Symmetrical connecting ear plates extend integrally from the middle of the base plate to both sides between the base plate and the rolled edge. 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 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.

[0023] There are three types of interlocking fixing components between keels:

[0024] In a single-row configuration, each keel has an interlocking fixing assembly consisting of a row of C-shaped inserts. The openings of the C-shaped inserts face the length of the horizontal keel. The connection methods include a single plate with two holes or two ear plates with a single hole, corresponding to an externally mounted column keel.

[0025] Parallel configuration: Each keel interlocking fixing assembly includes a row of two C-shaped insert plates. The openings of the C-shaped insert plates are oriented outwards and facing away from each other along the length of the horizontal keel. The connection method is a double-ear plate with a single hole, corresponding to two opposing upright keels.

[0026] The double-row type includes two rows of C-shaped insert plate groups for each keel. The openings of the C-shaped insert plates are set opposite each other with their openings facing outwards, along the width of the horizontal keel. The edges of the insert plates of the two C-shaped insert plates are flush with the edges of the base plate. The connection method is double ear plates with a single hole, corresponding to two longitudinally facing column keels.

[0027] It also includes an extension core keel set between the ends of the column keel. The extension core keel is adapted to the inner wall of the cavity of the side groove and the outer contour of the central groove protrusion and is integrally formed. The extension core keel is anchored to the column keel on each side by extension bolts.

[0028] The extended insert keel 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 outside the central groove protrusion plate. 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 column keel and is anchored by an extension bolt.

[0029] Compared with the prior art, this utility model has the following features and beneficial effects:

[0030] This utility model designs a composite cross-section keel multi-directional connection external partition wall system, which adopts an integrally formed arch-shaped opening structure column keel and external brackets. The main body is connected through the keel fixing holes of the central groove convex plate, and the external brackets are installed through the keel external connection holes of the three side groove plates, forming a two-way force system with stable structure.

[0031] This utility model also designs a horizontal keel and keel interlocking fixing component that matches the column keel, making it applicable to the external wall hanging system. The entire process is connected by bolts, with nail-free installation, which is more stable than the screw method of light steel keel and can be recycled. The open-type installation process inserts the plug from the side, which solves 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 the gap between the plug and the keel under external force. The plug has a simple structure and low manufacturing cost, overcoming many drawbacks of the existing partition wall keel installation method, and realizing the conversion and combination of the same keel between external hanging systems in different directions.

[0032] This invention offers high cost-effectiveness, reducing the types and quantities of materials required and lowering procurement costs; it also reduces storage space requirements and lowers storage costs. Furthermore, it boasts high construction efficiency, avoiding frequent changes in the keel structure during construction and shortening the construction period; it simplifies the construction process, reducing difficulty and error rates. This invention improves decorative quality, enhances structural stability, and reduces gaps, loosening, and stress concentration caused by connection problems; it also enhances aesthetics, resulting in natural transitions between decorative surfaces. Finally, this invention is highly adaptable, suitable for various interior spaces and finishing materials, and has a wide range of applications. Attached Figure Description

[0065] See Figure 2-3 As shown, the external attachment 2 is a corner piece, including a parallel leg 21 anchored to the panel 5, and an external attachment leg 23 perpendicular to the parallel leg 21. The external attachment leg 23 is provided with a hook 22 that hangs vertically downward to the keel external connection hole 16. The back of the panel 5 is attached to the keel external connection hole 16 via the external attachment 2. Each keel external connection hole 16 contains one external attachment 2 or two external attachments 2 arranged symmetrically back to back.

[0066] See Figure 6 As shown, the horizontal keel 3 consists of the ceiling keel and the floor keel, which are connected to the ceiling and the ground respectively. The cross-section of the horizontal keel 3 is a U-shaped groove, including an integrally formed bottom web plate 31 and side panel 32. The column keel 1 is inserted into the U-shaped groove of the horizontal keel 3.

[0067] See Figure 7-8As shown, the bottom web plate 31 has component connection holes arranged in a fixed module along its length. These connection holes include alternately spaced snap-fit ​​holes 35 and component bolt holes 36. The snap-fit ​​holes 35 are rectangular holes arranged in symmetrical groups. The component bolt holes 36 are arranged in a row along the length of the horizontal keel 4, with a component bolt hole 36 centered between adjacent groups of snap-fit ​​holes 35. The opposite side panels 32 of the bottom web plate 31 are concave upwards, 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 accommodate vibration-damping rubber pads 10 and further conceal bolt heads.

[0068] See Figure 9 As shown, the interlocking fixing assembly 4 between the keels includes a C-shaped insert plate 41 and a base plate 42 that are connected together. The C-shaped insert plate 41 is inserted into the base plate 42. The opening direction of the C-shaped insert plate 41 corresponds to the opening direction of the side groove 12. The central protrusion 11 is inserted into the C-shaped insert plate 41. The insert plate side plate 412 of the C-shaped insert plate 41 is inserted into the side grooves 12 on both sides along the outer wall of the inner side plate 112.

The base plate 42 also has insertion holes 422 and base connection holes 425 that correspond to the component bolt holes 36 and are anchored by structural bolts 8. Four snap-fit ​​holes 35 in two adjacent groups correspond to four base snap-fit ​​edges 421 on one base plate 42. The base snap-fit ​​edges 421 mate with the snap-fit ​​holes 35 of the horizontal keel 3, serving a positioning and limiting function.

[0070] The C-shaped insert plate 41 has an insert plate connection hole 414 on its web 411. The insert plate connection hole 414 is a vertical elongated oval hole. 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 plate and side plate are connected as one unit by a snap-fit ​​method. The insert plate connection hole 414 is aligned with the keel fixing hole 14 and anchored by the column bolt 13. The relative position of the column keel 1 and the C-shaped insert plate 41 is adjusted according to the corresponding position of the insert plate connection hole 414 and the keel fixing hole 14.

[0071] The component bolt holes 36 include two types:

[0072] See Figure 7 As shown, in single hole 36a, structural bolt 8 passes directly through the single hole and is anchored to the base connection hole 425;

[0073] See Figure 8As shown, there is a double hole 36b and a central hole 361 with double sliding holes 362 on both sides; the structural bolt 8 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.

[0074] The base plate 42 includes two types:

[0075] See Figure 9-10 As shown, the single board 42a has a base connection hole 425 located on the outside of the C-shaped insert 41.

[0076] See Figure 11-13 As shown, the double ear plates 42b, the base snap-fit ​​rolled edge 421, and the base plate 42 extend integrally to both sides from the middle to form symmetrical connecting ear plates 423. The connecting ear plates 423 are set along the length direction of the horizontal keel 3. The base connecting hole 425 is set at the end of the connecting ear plate 423. The connection between the base plate 42 and the connecting ear plate 423 is bent inward 424 downward. The height of the outward convex bending of the base snap-fit ​​rolled edge 421 relative to the base plate 42 is greater than the height of the inward bending of the connecting ear plate 423 relative to the base plate 42. At the same time, the height of the inward bending 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.

[0077] The interlocking fixing assembly 4 between the keels includes three types:

[0078] See Figure 14-15 As shown, in the single-row 4a, each keel interlocking fixing component 4 includes a row of C-shaped insert plates 41. The opening of the C-shaped insert plate 41 faces the length direction of the horizontal keel 3. The connection method includes a single plate 42a with double holes 36b or double ear plates 42b with single holes 36a. Correspondingly, an external column keel 1 is hung. The installation position of the C-shaped insert plate 41 is to ensure that the vertical center axis of the keel after the column keel 1 and the C-shaped insert plate 41 are installed coincides with the center of the base plate 42.

[0079] See Figure 16-17 As shown, in parallel configuration 4b, each keel interlocking fixing component 4 includes a row of two C-shaped insert plate groups. The openings of the C-shaped insert plates 41 are all set opposite to each other along the length of the horizontal keel 3, with the openings facing outwards. The connection method is that the double ear plate 42b cooperates with the single hole 36a, corresponding to the external hanging of two opposing column keels 1. Each keel interlocking fixing component 4 includes a row of two C-shaped insert plate groups. The openings of the C-shaped insert plates 41 are all set opposite to each other along the length of the horizontal keel 3, with the openings facing outwards. The insert plates of the two C-shaped insert plates 41 are back-to-back, and the vertical central axis of the C-shaped insert plate group coincides with the center of the base plate 92.

[0080] See Figure 18-19As shown, the double-row 4c, each keel interlocking fixing component 4 includes two rows of C-shaped insert plate groups. The openings of the C-shaped insert plates 41 are all set opposite to each other with their openings facing outwards along the width direction of the horizontal keel 3. 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 connection method is that the double ear plates 42b cooperate with the single hole 36a, corresponding to two longitudinally facing column keels 1. The vertical central axis of the C-shaped insert plate group coincides with the center of the base plate 42.

[0081] See Figure 20-22 As shown, the composite cross-section keel multi-directional connection external partition wall system also includes an extension insert keel 6 disposed between the ends of the column keel 1. The extension insert keel 6 is adapted to and integrally formed with the inner wall of the cavity of the side grooves 12 and the outer contour of the central groove protrusion 111. The extension insert keel 6 is anchored to each side of the column keel 1 by extension bolts 7. The extension insert keel 6 includes an insert roll plate 61 built into the side groove 12 and an insert connecting plate 62 that connects the two insert roll plates 61 laterally. The insert connecting plate 62 is located outside the central groove protrusion 111. The insert connecting plate 62 forms an adaptive concave shape at the side plate 123. The insert connecting plate 62 is provided with two vertical insert elongated holes 63. Each insert elongated hole 63 corresponds to the keel fixing hole 14 at the end of one side of the column keel 1 and is anchored by extension bolts 7.

[0082] The installation method and construction steps for this composite cross-section keel multi-directional connection external partition wall system are as follows:

[0083] Step 1: Perform measurement and layout to accurately locate the positions of each installation component and panel 5, and select the form of interlocking fixing component 4 between the keels.

[0084] Step 2: Set the horizontal keel 8 as the ceiling keel and the ground keel, and fix it to the ceiling and the ground by passing the structural bolts 8 through the component bolt holes 36. The hidden receiving cavity 34 of the ground keel is filled with vibration damping rubber pads 10.

[0085] Step 3,

[0086] When constructing single-row type 4a and parallel type 4b: connect the inter-keel 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 side, and separate the column keel 1 and the C-shaped insert plate 41 with vibration isolation rubber pads 10, and then fix the column keel 1 and the C-shaped insert plate 41 with column bolts 13.

[0087] During double-row 4c construction: Connect the interlocking fixing component 4 between the keel and 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 back sides respectively. Place the vibration isolation rubber pad 10 between the C-shaped insert plate 41 and the column keel 1. Insert the vibration isolation rubber block 9 between the two C-shaped insert plates 41. Then fix the column keel 1, the vibration isolation rubber block 9 and the C-shaped insert plate 41 with the column bolt 13.

[0088] Step 4: Attach the back of panel 5 to the keel external connection hole 16 using the external bracket 2; finally, check the stability of each connection node and make adjustments to complete the partition wall installation.
