Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, and in particular to an interior decoration light steel keel composite component. Background Technology

[0002] Currently, most fully furnished apartments use light steel keel as the support for the exterior walls to facilitate the installation of decorative panels. For integrated decoration, the light steel keel adopts an integrated structure, ultimately forming a complete frame structure by welding the top keel, bottom keel, vertical keel, and intermediate keel. Sound insulation panels are installed within the frame to increase the sound insulation of the house and reduce the problem of poor sound insulation caused by developers cutting corners in construction.

[0003] Although an integrated structure is adopted, the integrated keel structure makes it difficult to install sound insulation panels such as sound insulation boards and fireproof boards. When installing sound insulation panels on the integrated keel, the sound insulation panels are all placed on the same plane. The sound wave transmission path is blocked and the path remains basically unchanged, resulting in poor sound insulation effect. Utility Model Content

[0004] The purpose of this utility model is to provide an interior decorative light steel keel composite component to solve the problems encountered in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An interior decorative light steel keel composite component includes a core, a first keel, and a second keel. The core has an S-shaped cross-section. The upper part of the core is provided with a first sound insulation board mounting groove, and the outside of the first sound insulation board mounting groove is provided with a first retaining part that engages with the first keel. The lower part of the core is provided with a second sound insulation board mounting groove, and the outside of the second sound insulation board mounting groove is provided with a second retaining part that engages with the second keel.

[0007] In this composite keel assembly, a weight-reducing groove is provided in the middle of the core, and the weight-reducing groove is rectangular in shape.

[0008] In the above scheme, the second sound insulation panel mounting groove is provided with a second hook groove that is pulled to the first keel on the side near the weight reduction groove, and a first slot that is engaged with the first keel is provided between the first sound insulation panel mounting groove and the first holding part.

[0009] In the above scheme, the first sound insulation panel mounting groove is provided with a first hook groove that is pulled to the second keel on the side near the weight reduction groove, and a second slot that is engaged with the second keel is provided between the second sound insulation panel mounting groove and the second holding part.

[0010] In the above scheme, the first retaining part has a T-shaped structure, the first slot is located on the outside of the first retaining part, and the inner side of the first retaining part is provided with a first main sliding groove; the first main sliding groove is used to engage and adapt with the second retaining part of the adjacent bone core. The top of the first retaining part is provided with a first auxiliary sliding groove, and the outer surface of the first auxiliary sliding groove has a serrated structure; the side of the first main sliding groove near the first sound insulation plate mounting groove is also provided with a serrated structure.

[0011] In the above scheme, the second holding part has an inverted T-shaped structure, the second slot is located on the outside of the second holding part, and the inner side of the second holding part is provided with a second main sliding groove; the second main sliding groove is used to engage and fit with the first holding part of the adjacent other core. The bottom of the second holding part is provided with a second auxiliary sliding groove, and the outer surface of the second auxiliary sliding groove has a serrated structure; the side of the second main sliding groove near the second sound insulation plate mounting groove is also provided with a serrated structure.

[0012] In addition, as a preferred embodiment, the outer walls of the first sound insulation panel mounting groove and the second sound insulation panel mounting groove are respectively provided with weight reduction grooves, and the included angle of the first sound insulation panel mounting groove and the included angle of the second sound insulation panel mounting groove are respectively provided with top heads, the top of the top head being flush with the middle outer wall of the core.

[0013] Furthermore, as a preferred embodiment, the first keel and the second keel are respectively provided with wiring holes and horizontal keel insertion holes; the interior of the first sound insulation panel mounting groove and the interior of the second sound insulation panel mounting groove are used to install sound insulation panels, and the core is fixed to the sound insulation panel with screws.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: The cross-section of the core is S-shaped, which facilitates the installation of sound insulation panels that are not on the same plane. This folds and blocks sound waves, causing them to be absorbed or reflected. The reflected sound waves, due to their different latitudes, are gradually segmented and dissipate, achieving a sound insulation and noise reduction effect. The upper and lower parts of the core are respectively provided with first sound insulation panel mounting grooves for installing the sound insulation panels. By effectively engaging both ends of the first or second keel with the core, and thus pulling the core together, a stable composite keel is formed. The S-shaped core allows for the installation of the sound insulation panels on different planes, effectively folding and blocking sound waves, affecting the normal transmission path of the sound waves and achieving a noise reduction effect. Furthermore, to further enhance the sound insulation effect, rock wool is installed in the gaps on both sides of the folded sound insulation panel. Rock wool also has excellent sound wave absorption properties; sound waves reflected or passing through the sound insulation panel are absorbed again by the rock wool, greatly reducing sound wave transmission.

Detailed Implementation

[0025] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0026] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0027] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1, as Figure 1 and Figure 2 As shown, an interior decorative light steel keel composite component includes a core 1, a first keel 2, and a second keel 3. The core 1 is made of PVC material and is injection molded in one piece to connect the front and rear keels. The first keel 2 and the second keel 3 are made by bending galvanized steel. A notch is set at the angle between the two keels to increase the rigidity of the keel.

[0029] The core 1 has an S-shaped cross-section, facilitating the installation of sound insulation panels 7 that are not on the same plane. This folds and blocks sound waves, causing them to be absorbed or reflected. The reflected sound waves, due to their different latitudes, are gradually segmented and dissipate. The upper part of the core 1 has a first sound insulation panel mounting groove 12 for installing the sound insulation panel 7. The exterior of the first sound insulation panel mounting groove 12 has a first retaining part 13 that engages with the first keel 2. The lower part of the core 1 has a second sound insulation panel mounting groove 14, also for installing the sound insulation panel 7. The exterior of the second sound insulation panel mounting groove 14 has a second retaining part 15 that engages with the second keel 3.

[0030] The first keel 2, the second keel 3 and the core 1 can be stacked together to be used as a vertical keel. The first keel 2 and the second keel 3 can be different in size. According to market demand, they can be combined to form three different thicknesses of vertical keels, namely 118 mm, 145 mm and 172 mm.

[0031] As a preferred embodiment, in this composite keel assembly, a weight-reducing groove 11 is provided in the middle of the core 1. The weight-reducing groove 11 has a rectangular structure. The weight-reducing groove 11 in the middle hole absorbs sound waves and then collidees with each other inside, which also has a certain noise reduction effect.

[0032] Example 2, based on the scheme of Example 1, in order to fix the first keel 2 and the second keel 3, the core 1 is specifically designed with a second hook groove 141 on the side of the second sound insulation plate mounting groove 14 near the weight reduction groove 11, which is used to pull the first keel 2, so that one end of the first keel 2 is hung on the second hook groove 141 to hold the core 1. A first slot 131 is provided between the first sound insulation plate mounting groove 12 and the first holding part 13 to engage with the first keel 2, so that the other end of the first keel 2 is inserted into the first slot 131.

[0033] For fixing the second keel 3, a first hook groove 121 is provided on the side of the first sound insulation panel mounting groove 12 near the weight reduction groove 11, which is used to pull the second keel 3, and to hang one end of the second keel 3 on the first hook groove 121 to hold the core 1. A second slot 151 is provided between the second sound insulation panel mounting groove 14 and the second holding part 15 to engage with the second keel 3, and to insert the other end of the second keel 3 into the second slot 151.

[0034] This design allows both ends of the first keel 2 or the second keel 3 to be effectively engaged with the core 1, thus pulling the core 1 together to form a stable composite keel. Both the first keel 2 and the second keel 3 have a "6"-shaped structure, with a reserved space in the middle for installing the sound insulation panel 7. The S-shaped core 1 is used to install the sound insulation panel 7 on different planes, effectively folding and blocking sound waves, thus affecting the normal transmission path of sound waves and achieving a noise reduction effect.

[0035] As a preferred embodiment, to secure the end of the first keel 2 or the second keel 3, a first guide opening 132 is provided on the outside of the first slot 131. The two sides of the first guide opening 132 are inwardly inclined oblique structures, facilitating the insertion of one end of the first keel 2 into the first slot 131. Similarly, a second guide opening 152 is provided on the outside of the second slot 151. The two sides of the second guide opening 152 are inwardly inclined oblique structures, facilitating the insertion of one end of the second keel 3 into the second slot 151.

[0036] Example 3, please refer to Figure 3 When assembling the keel frame using the scheme of Example 1 or 2, it can be assembled as follows.

[0037] The first keel 2, the second keel 3, and the core 1 are stacked together to form a vertical keel, which is set on both sides of the keel frame or evenly distributed in the middle. The top keel 4 is installed on the top of the vertical keel, the bottom keel 5 is installed on the bottom of the vertical keel, and the horizontal keel 6 connects the two adjacent vertical keels. Furthermore, sound insulation panels 7 are installed in the core 1, which has an S-shaped folded surface, located in the first sound insulation panel mounting groove 12 and the second sound insulation panel mounting groove 14.

[0038] As a preferred embodiment, wiring holes 21 and horizontal keel insertion holes 22 are respectively provided on the frame of the first keel 2 and the second keel 3. The wiring holes 21 are used to thread wires in the keel, facilitating circuit connection and enabling concealed installation of lighting fixtures or switch circuits. The horizontal keel insertion holes 22 are used to position the horizontal keel 6, ensuring it is horizontally arranged between two adjacent vertical keels.

[0039] Example 4, please refer to Figure 4-6 To further enhance sound insulation, rock wool 8 is installed in the gaps on both sides of the folded sound insulation panel 7. The rock wool 8 is positioned between the sound insulation panel 7 and the horizontal keel 6. Plasterboard 9 is provided on both sides of the keel assembly to sandwich the rock wool 8. The plasterboard 9 also serves to block sound waves, thus reducing noise. The rock wool 8 also effectively absorbs sound waves; sound waves reflected or transmitted through the sound insulation panel 7 are absorbed again by the rock wool 8, significantly reducing sound wave transmission.

[0040] for example Figure 6 As shown, if sound waves originate from the top, on the left side of this composite keel assembly, the sound waves first enter the gypsum board 9, then the thinner rock wool 8, then the sound insulation board 7, and finally, through penetration, enter the thicker rock wool 8, achieving a noise reduction effect. On the right side of the composite keel assembly, the sound waves first enter the thicker rock wool 8, then the sound insulation board 7, and then, through penetration, enter the thinner rock wool 8, achieving a noise reduction effect, finally passing through another layer of gypsum board 9. Entering from the right side of this composite keel assembly is the opposite of entering from the left. Therefore, when sound waves pass through this composite keel assembly, they need to undergo absorption and reflection by the sound insulation boards 7, which are located on different planes, as well as penetration, and also be absorbed by the two layers of rock wool 8, greatly reducing the transmission intensity of the sound waves.

[0041] Example 5: Based on Example 1 or 2, multiple cores 1 can be assembled and stacked together using the composite keel assembly designed in this paper.

[0042] Please continue reading. Figure 1 and Figure 2 For the upper connection structure of the core 1, the first holding part 13 has a T-shaped structure, the first slot 131 is located on the outside of the first holding part 13, and the inner side of the first holding part 13 is provided with a first main slide groove 134. The first main slide groove 134 is used to engage and adapt with the second holding part 15 of the adjacent core 1.

[0043] As a preferred embodiment, the top of the first holding part 13 is provided with a first auxiliary slide groove 133, the outer surface of the first auxiliary slide groove 133 is serrated, and the side of the first main slide groove 134 near the first sound insulation plate mounting groove 12 is also provided with a serrated structure. By designing a uniform serrated structure, it is convenient for two adjacent cores 1 to be assembled and interlocked together.

[0044] In addition, for the lower connection structure of the core 1, the second holding part 15 has an inverted T-shaped structure, the second slot 151 is located on the outside of the second holding part 15, and the inner side of the second holding part 15 is provided with a second main slide groove 154. The second main slide groove 154 is used to engage and adapt with the first holding part 13 of the adjacent core 1.

[0045] As a preferred embodiment, the bottom of the second retaining part 15 is provided with a second auxiliary sliding groove 153, the outer surface of which has a serrated structure. The second main sliding groove 154 also has a serrated structure on the side near the second sound insulation plate mounting groove 14. By designing a uniform serrated structure, it is convenient for two adjacent cores 1 to interlock and overlap after assembly.

[0046] Specifically, the side of the second retaining part 15 near the second main slide groove 154 overlaps the groove of the first main slide groove 134, while the side of the first main slide groove 134 near the first main slide groove 134 overlaps the groove of the second main slide groove 154. When assembling the two overlapping keel components... Figure 7 As shown, the two bone cores 1 are interlocked and engaged together.

[0047] As a preferred embodiment, because the first auxiliary slide groove 133 is provided with a serrated structure, when connecting to the second main slide groove 154 located in another core 1, it engages with the serrated structure in the second main slide groove 154 to prevent lateral sliding. Similarly, because the second auxiliary slide groove 153 is provided with a serrated structure, when connecting to the first main slide groove 134 located in another core 1, it engages with the serrated structure in the first main slide groove 134 to prevent lateral sliding. Furthermore, because the first retaining part 13 and the second retaining part 15 are mutually engaged and locked, restricting vertical movement, the assembled composite keel assembly is very stable.

[0048] Please see Figure 5 Of course, when the upper and lower parts of the core 1 need to be pulled and inserted with the first keel 2 and the second keel 3, only the upper structure of the core 1 needs to be inserted and fixed with the first keel 2, and the lower structure of the core 1 needs to be inserted and fixed with the second keel 3. By inserting the two cores 1 together, two layers of sound insulation panels 7 can be installed, because one core 1 can install two on the left and right, and two cores 1 can install four sound insulation panels 7.

[0049] Please see Figure 6The interior of the first sound insulation panel mounting slot 12 and the interior of the second sound insulation panel mounting slot 14 are used to install the sound insulation panels 7. Because two interlocking cores 1 are designed, four sound insulation panels 7 can be installed after assembly, which can better fold and block sound waves. Combined with rock wool 8, this further reduces sound wave transmission. To limit the movement of the sound insulation panels 7, not only are the first and second sound insulation panel mounting slots 12 and 14 used to restrict their forward, backward, left, and right movements, but the cores 1 are also fixed to the sound insulation panels 7 with screws 16, restricting their movement in the vertical direction.

[0050] Example 6, based on Examples 1-5, please refer to... Figure 1 and Figure 2 To further reduce the weight of the core 1, weight-reducing grooves 122 are respectively provided on the outer wall of the first sound insulation plate mounting groove 12 and the outer wall of the second sound insulation plate mounting groove 14. However, it should be noted that even if weight-reducing grooves 122 are designed, the outer wall thickness of the first sound insulation plate mounting groove 12 and the outer wall thickness of the second sound insulation plate mounting groove 14 should be equivalent to the thickness of the main frame of the core 1 to maintain stable support. The thickness of the core 1 can be uniformly set at 3-5 mm.

[0051] Tops 123 are provided at the included angle of the first sound insulation panel mounting groove 12 and the included angle of the second sound insulation panel mounting groove 14. The top of the top 123 is flush with the middle outer wall of the core 1. When the first keel 2 and the second keel 3 are installed, the inner wall of the first keel 2 or the second keel 3 can be partially flush with the weight reduction groove 11, thereby effectively supporting the connection position after the insertion and snap-fit.
