Description

Technical Field

[0001] This utility model relates to the field of keel structure technology, and in particular to a keel structure for a non-combustible sound-absorbing panel. Background Technology

[0002] In the field of modern architectural acoustic design and interior environment optimization, non-combustible sound-absorbing panels are widely used as a key material in places with high acoustic requirements, such as concert halls, conference rooms, and cinemas, as well as in office buildings and residential buildings, to reduce noise interference and improve sound quality. The performance of the keel structure, as the support system for the installation of sound-absorbing panels, directly affects the installation effect and functionality of the panels.

[0003] Currently, common sound-absorbing panel keel structures on the market generally suffer from fixed structural forms and poor installation flexibility. The frame area dimensions of traditional keel structures are usually fixed specifications, making it difficult to flexibly adjust to the dimensions of different sound-absorbing panels. This necessitates secondary processing or customization of the keel when installing non-standard sound-absorbing panels, increasing construction costs and time. Furthermore, the installation position and number of connecting components in traditional keels lack adjustability, failing to meet the needs of diverse installation scenarios. For example, when installing on different surfaces such as ceilings and walls, different types of keel structures are often required, resulting in poor versatility and reduced construction efficiency.

[0004] In view of the above-mentioned defects of existing sound-absorbing panel keel structures, there is an urgent need to develop a non-combustible sound-absorbing panel keel structure that is flexible, easy to install, and highly versatile, in order to meet the increasingly diverse installation needs and higher construction standards in the field of architectural acoustics. Utility Model Content

[0005] In order to overcome the shortcomings mentioned in the background art, this utility model provides a keel structure for non-combustible sound-absorbing panels.

[0006] Technical Solution: A keel structure for non-combustible sound-absorbing panels includes a main keel frame, secondary keels, connecting keels, and sound-absorbing panels. The main keel frame serves as the basic frame, with secondary keels arranged laterally in the middle. Multiple connecting keels are arranged between the front and rear sides of the secondary keels and the main keel frame using an interval sliding installation method. Multiple notches are spaced apart on the secondary keels, and multiple through holes are spaced apart on both the secondary keels and the main keel frame. By screwing through these through holes and the pre-set slots on the connecting keels, the connecting keels are fixed to the secondary keels and the main keel frame. The main keel frame, secondary keels, and connecting keels cooperate with each other to form multiple frame areas, and the sound-absorbing panels are installed in the frame areas.

[0007] In addition, it is particularly preferred that the main keel frame also includes connecting blocks. Multiple connecting blocks are installed on both sides of the main keel frame using a spaced sliding snap-fit ​​method. The connecting blocks are symmetrically provided with mounting holes that are aligned with the through holes on the main keel frame for installing screws.

[0008] Furthermore, it is particularly preferred that the device also includes a telescopic rod and a mounting nut. The upper part of the connecting block has a groove, and the mounting nut is connected to the groove. The telescopic rod is inserted into the connecting block, and the lower end of the telescopic rod is machined with a threaded groove, which is threadedly connected to the mounting nut.

[0009] Furthermore, it is particularly preferred that the connecting block has symmetrically provided fixing holes.

[0010] Furthermore, it is particularly preferred that the edge of the sound-absorbing panel has elastic protrusions that are adapted to the frame area.

[0011] In addition, it is particularly preferred that the main keel frame, secondary keel and connecting keel are all made of hot-dip galvanized steel sheet stamped into metal frame.

[0012] Furthermore, it is particularly preferred that the mounting nut is an embedded hexagonal flange nut, which is embedded in the groove of the connecting block, and the outer diameter of the mounting nut is 1-2 mm smaller than the diameter of the groove.

[0013] Furthermore, it is particularly preferred that the sound-absorbing panel has a composite structure, including a 0.8-1.2 mm thick galvanized steel sheet base layer, a 50-100 mm thick centrifugal glass wool sound-absorbing layer, and a 0.5 mm thick perforated aluminum panel.

[0014] In addition, it is particularly preferred that the grooves on both sides of the main keel frame for the sliding of the connecting blocks are provided with a Teflon coating with a coating thickness of 50-70μm.

[0015] In addition, it is particularly preferred that the telescopic boom is made of Q235B grade carbon steel seamless steel pipe with a wall thickness of 2.5-3 mm, and the outer surface is hot-dip galvanized and then sprayed with 60-80μm thick epoxy zinc-rich primer.

[0016] Beneficial effects: 1. The connecting keel can slide left and right and be inserted by aligning with the notch of the secondary keel. With the through holes distributed at intervals on the main and secondary keels, the installation position can be flexibly adjusted, the size of the frame area can be changed, and different specifications of sound-absorbing panels can be adapted to meet diverse installation needs.

[0017] 2. The number and position of the connecting blocks can be flexibly adjusted, and the combination of telescopic hangers and mounting nuts allows for free switching between ceiling-mounted and wall-mounted modes, expanding the application scenarios of the keel structure and improving its versatility.

[0024] Example: A keel structure for a non-combustible sound-absorbing panel, such as... Figures 1-3 As shown, the system includes a main keel frame 1, secondary keels 2, connecting keels 3, and sound-absorbing panels 4. The main keel frame 1 serves as the basic frame, with secondary keels 2 horizontally positioned in the middle. Multiple connecting keels 3 are arranged between the secondary keels 2 and the main keel frame 1 using a spaced-apart sliding installation method. The connecting keels 3 can be adjusted in the left and right directions. Multiple notches 5 are spaced apart on the secondary keels 2. When installing the connecting keels 3, aligning the connecting keel 3 with the notches 5 allows it to smoothly fit between the secondary keel 2 and the main keel frame 1. The notches 5 provide precise installation positioning space for the connecting keels 3, greatly improving the ease of installation and removal. Multiple through holes 6 are spaced apart on both the secondary keels 2 and the main keel frame 1, allowing screws to pass through these through holes 6 and... The pre-set holes and slots on the connecting keel 3 enable the connecting keel 3 to be securely fixed to the secondary keel 2 and the main keel frame 1. Since the through holes 6 are spaced apart, the installation position of the connecting keel 3 can be flexibly adjusted according to actual needs. The main keel frame 1, secondary keel 2 and connecting keel 3 cooperate with each other to form multiple frame areas. The sound-absorbing panel 4 is installed in the frame area. By adjusting the position of the connecting keel 3, the size of the frame area can be flexibly adjusted to adapt to the installation requirements of different specifications of sound-absorbing panels 4. The edge of the sound-absorbing panel 4 is provided with elastic protrusions that are adapted to the frame area. When the sound-absorbing panel 4 is installed in the frame area, the elastic protrusions of the frame area are embedded in the frame area, making the connection between the sound-absorbing panel 4 and the keel structure tighter and preventing the sound-absorbing panel 4 from shaking.

[0025] The sound-absorbing panel 4 has a composite structure, including a 0.8-1.2 mm thick galvanized steel plate base layer, a 50-100 mm thick centrifugal glass wool sound-absorbing layer, and a 0.5 mm thick perforated aluminum panel. The perforation rate is 15-20%, and the average sound absorption coefficient is ≥0.85 (125-4000Hz). The composite structure makes the sound-absorbing panel fireproof (Class A), environmentally friendly (formaldehyde-free glass wool), and lightweight (surface density ≤15kg / m²), making it suitable for places with strict acoustic requirements (such as recording studios and lecture halls).

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes connecting blocks 7, telescopic rods 10, and mounting nuts 12. Multiple connecting blocks 7 are installed on both the front and rear sides of the main keel frame 1 using a spaced sliding snap-fit ​​method. The grooves on both sides of the main keel frame 1 for sliding the connecting blocks 7 are coated with Teflon, with a coating thickness of 50-70μm and a friction coefficient ≤0.15, allowing for tool-free manual adjustment of the installation position. The connecting blocks 7 have symmetrical mounting holes 8 aligned with the through holes 6 on the main keel frame 1 for installing screws to fix the connecting blocks 7 to the main keel frame 1. The number and position of the connecting blocks 7 can be flexibly adjusted according to the actual installation scenario, enhancing the versatility and adaptability of the keel structure. The upper part of the connecting blocks 7 has a recessed... The mounting nut 12 is an embedded hexagonal flange nut, which is embedded in the groove of the connecting block 7. The outer diameter of the mounting nut 12 is 1-2 mm smaller than the diameter of the groove to ensure a flat surface and avoid installation interference caused by protrusions. A telescopic rod 10 is inserted into the connecting block 7. The lower end of the telescopic rod 10 is machined with a threaded groove 11, which is threaded to the mounting nut 12 to achieve detachable fixing. The telescopic rod 10 is made of Q235B grade carbon steel seamless steel pipe. The seamless structure avoids the risk of weld cracking and improves seismic performance. The outer surface is hot-dip galvanized and then sprayed with 60-80μm thick epoxy zinc-rich primer, which is suitable for outdoor or highly corrosive environments. Fixing holes 9 are symmetrically opened on the left and right sides of the connecting block 7.

[0027] When the keel structure is used to install the sound-absorbing panel 4 on the ceiling, the main keel frame 1 and the sound-absorbing panel 4 are hoisted by the telescopic hanger 10. The telescopic hanger 10 can be flexibly adjusted in length according to the height requirements of the actual installation environment to ensure that the sound-absorbing panel 4 can be accurately installed at the appropriate height position, thus ensuring the installation effect and sound absorption performance. When the main keel frame 1 is used to install the sound-absorbing panel 4 on the wall, the telescopic hanger 10 is not needed. It is removed from the connecting block 7. At this time, the main keel frame 1 and the sound-absorbing panel 4 are attached to the wall surface, and the connecting block 7 is tightly attached to the wall. By using screws to pass through the fixing holes 9 on the connecting block 7, the connecting block 7 can be firmly fixed to the wall, thereby completing the stable installation of the sound-absorbing panel 4 on the wall.

[0028] The main keel frame 1, secondary keel 2 and connecting keel 3 are all made of hot-dip galvanized steel sheet stamping to form a stable metal frame, which can withstand the self-weight of the sound-absorbing panel 4 and external loads (such as the downward force during ceiling installation), and avoid structural deformation or collapse.
