Description

Technical Field

[0001] This utility model relates to the technical field of thermal break insulation and sound insulation vertical keel, specifically a prefabricated quick-installation thermal break insulation and sound insulation vertical keel. Background Technology

[0002] Thermally broken and soundproof vertical keel is a vertical frame component used in non-load-bearing interior partition wall systems. It adopts "thermal break" technology, which separates the metal keels on both sides through high-strength non-metallic material connectors, thereby effectively blocking heat conduction and sound bridges formed through the keel, significantly improving the overall thermal insulation and sound insulation performance of the wall. In existing technology, thermally broken and soundproof vertical keels are mainly composed of sound insulation panels and metal keels. The sound insulation panels have elastic arms with protrusions on both sides. The rolled edges of the metal keel supports serve as locking points. When the elastic arms of the connectors are aligned with the inside of the rolled edges of the keels and the connectors are pressed, the protrusions on the elastic arms undergo elastic deformation due to the compression of the rolled edges of the keels. When the protrusions cross the rolled edges and reach their final position, the elastic arms rebound, and the protrusions will tightly fasten behind the rolled edges, thus fixing the two together.

[0003] In existing technologies, although thermally broken and sound-insulating vertical keels are connected by snap-fit ​​between the elastic arms on both sides of the sound insulation panel and the rolled edge of the metal keel, this reliance on a single elastic snap-fit ​​means that the connection point is mainly maintained by the elastic deformation of the local material. Under long-term vibration or load, the snap-fit ​​interface is prone to loosening or slippage. This not only causes displacement and friction noise between the sound insulation panel and the metal keel, affecting the quietness of use, but also weakens the long-term reliability of the connection, posing a potential risk to the overall structural safety. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated, quick-installation thermal break and sound insulation vertical keel, which solves the problem of relying on a single elastic clip. Since the connection point mainly relies on the elastic deformation of local materials, the clip interface is prone to loosening or slippage under long-term vibration or load. This not only causes displacement and friction noise between the sound insulation board and the metal keel, affecting the quietness of use, but also weakens the long-term reliability of the connection, posing a potential risk to the overall structural safety.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a prefabricated, quick-installation thermal break and sound insulation vertical keel, comprising a sound insulation panel and metal keels fixedly installed at both ends. The metal keel includes a side plate and two L-shaped connecting plates. The two connecting plates extend from one edge of the side plate and are arranged symmetrically to form a placement groove for accommodating the sound insulation panel. Multiple mounting grooves are provided on the outer side of the connecting plates. Each mounting groove has a reinforcing structure inside. The reinforcing structure includes a mounting plate adapted to the shape of the mounting groove. The mounting plate has barbs on the side facing the sound insulation panel for pressing the side of the sound insulation panel. A locking block is provided on the other side of the mounting plate. An opening is provided on the inner surface of the mounting groove. The locking block passes through the opening and forms a locking engagement with the outer surface of the connecting plate.

[0007] Furthermore, anti-slip stripes are provided on the outer surfaces of both connecting plates facing each other, and the anti-slip stripes are in close contact with the outer surface of the sound insulation plate.

[0008] Furthermore, the side plate and the connecting plate are integrally formed.

[0009] Furthermore, the outer side of the side plate is provided with a plurality of first mounting holes, and the outer side of the sound insulation plate is provided with a plurality of second mounting holes, wherein the number of first mounting holes and second mounting holes is the same.

[0010] Furthermore, the barbs are provided in multiple quantities and are arranged in an array on the mounting plate.

[0011] This utility model has the following beneficial effects:

[0012] (1) The reinforcement structure of this utility model forms a deep interlock by embedding the array of barbs on the mounting plate into the sound insulation plate, which effectively suppresses the relative displacement between the metal keel and the sound insulation plate. At the same time, the rigid interlock between the back side block and the outer surface of the connecting plate forms a two-way constraint, which improves the anti-slip and anti-loosening effect of the connection. It solves the problem of interface relaxation caused by material fatigue in the elastic buckle of traditional metal keel. It not only eliminates the friction noise caused by loosening and ensures quiet use, but also greatly enhances the structural stability and safety reliability of the vertical keel under long-term vibration load.

[0013] (2) The close contact between the anti-slip stripes and the surface of the sound insulation board effectively increases the static friction resistance between the two, which not only further suppresses the small displacement or slippage tendency that may occur in the long-term use of the sound insulation board, but also works in synergy with the reinforcement structure to jointly improve the stability of the overall connection, thereby enhancing the anti-loosening ability and long-term reliability of the vertical keel under dynamic load.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5As shown, this utility model is a prefabricated quick-install thermal break and sound insulation vertical keel, including a sound insulation board 1 and metal keels 2 fixedly installed at both ends. The metal keel 2 includes a side plate 21 and two L-shaped connecting plates 22. The two connecting plates 22 extend from one side edge of the side plate 21 and are arranged symmetrically to each other, thereby forming a placement groove for accommodating the sound insulation board 1. Multiple mounting grooves 23 are opened on the outer side of the connecting plate 22. Each mounting groove 23 is provided with a reinforcing structure 3 inside. The reinforcing structure 3 includes a mounting plate 31 that is adapted to the shape of the mounting groove 23. The mounting plate 31 is provided with barbs 32 for pressing the side of the sound insulation board 1 on the side facing the sound insulation board 1. A locking block 33 is provided on the other side of the mounting plate 31. An opening is opened on the inner surface of the mounting groove 23. The locking block 33 passes through the opening and forms a locking fit with the outer surface of the connecting plate 22.

[0025] Among them, the reinforcement structure 3 is embedded in the sound insulation board 1 by the array of barbs 32 on the mounting plate 31 to form a deep engagement, which effectively suppresses the relative displacement between the metal keel 2 and the sound insulation board 1. At the same time, the back side buckle 33 is rigidly engaged with the outer surface of the connecting plate 22 to form a two-way constraint, which improves the anti-slip and anti-loosening effect of the connection. It solves the problem of interface relaxation caused by material fatigue in the elastic buckle in the traditional metal keel. It not only eliminates the friction noise caused by loosening and ensures quiet use, but also greatly enhances the structural stability and safety reliability of the vertical keel under long-term vibration load.

[0026] The outer surfaces of the two connecting plates 22 are provided with anti-slip stripes, which are in close contact with the outer surface of the sound insulation plate 1.

[0027] Among them, the close contact between the anti-slip stripes and the surface of the sound insulation board 1 effectively increases the static friction resistance between the two, which not only further suppresses the slight displacement or slippage tendency that may occur in the sound insulation board 1 during long-term use, but also works in synergy with the reinforcement structure 3 to jointly improve the stability of the overall connection, thereby enhancing the anti-loosening ability and long-term reliability of the vertical keel under dynamic load.

[0028] Side plate 21 and connecting plate 22 are integrally formed structures;

[0029] The outer side of the side panel 21 is provided with a plurality of first mounting holes 4, and the outer side of the sound insulation panel 1 is provided with a plurality of second mounting holes 5, the number of first mounting holes 4 and second mounting holes 5 being the same.

[0030] Among them, the first mounting hole 4 and the second mounting hole 5 cooperate to form a standardized installation path that runs through the whole, ensuring that when the vertical keel is finally installed, the fasteners can pass through the sound insulation board 1 and the metal keel 2 synchronously and vertically, thus achieving a precise and efficient connection with the main body of the building and avoiding stress concentration or loosening of the connection caused by misaligned installation.

[0031] Multiple barbs 32 are provided and are arranged in an array on the mounting plate 31;

[0032] The array-shaped distribution of barbs 32 forms multiple uniform anchoring points on the contact surface of the sound insulation panel 1, thereby enhancing the bonding force between the reinforcement structure 3 and the sound insulation panel 1.

[0033] In use, align the mounting plate 31 of the independent reinforcing structure 3 with the pre-set mounting groove 23 on the connecting plate 22 of the metal keel 2 and apply pressure. At this time, the locking block 33 on the back side of the mounting plate 31 will accurately pass through the opening in the mounting groove 23 and form a firm locking fit with the outer surface of the connecting plate 22, realizing the rapid and precise pre-fixation of the reinforcing structure 3 on the metal keel 2, laying a rigid foundation for the subsequent connection with the sound insulation panel 1. Subsequently, the sound insulation panel 1 is placed into the placement groove formed by the two L-shaped connecting plates 22. During this process, the anti-slip stripes on the outer side of the connecting plate 22 first make close contact with the surface of the sound insulation panel 1, and achieve preliminary limiting and anti-slip effects by increasing static friction. After the sound insulation panel 1 is installed in place, it is pre-fixed to the metal keel 2. The reinforcing structure 3 on the keel 2 has multiple barbs 32 arranged in an array on its mounting plate 31. Under its own elastic deformation, these barbs press tightly against and embed into the side wall of the sound insulation board 1, forming a deep and irreversible interlock. At this point, the entire installation process is completed. The reinforcing structure 3 is rigidly locked to the metal keel 2 by the locking block 33 on its other side, and is also deeply anchored to the sound insulation board 1 by the array of barbs 32. This creates a two-way constraint between the sound insulation board 1 and the metal keel 2. The integrated metal keel 2 structure, along with the corresponding first mounting hole 4 and second mounting hole 5 on the side plate 21 and the sound insulation board 1, work together to achieve tool-free quick installation of the entire vertical keel assembly, absolute reliability of the connection points, zero abnormal noise under vibration, and long-term sound insulation and heat insulation performance.
