Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge hole plate installation technology, specifically to a quick-installation keel for bridge hole plates. Background Technology
[0002] Perforated sound-absorbing alloy panels, also known as bridge-hole reflective sound-absorbing alloy panels, are an ideal sound-absorbing decorative material. They have advantages such as sound absorption, environmental friendliness, flame retardancy, heat insulation, thermal insulation, moisture resistance, mildew resistance, easy dust removal, easy cutting, mosaic capability, simple construction, good stability, good impact resistance, good independence, and high cost performance. They are mainly used in theaters, concert halls, museums, exhibition halls, libraries, interrogation rooms, galleries, auction halls, stadiums, lecture halls, multi-functional halls, hotel lobbies, hospitals, shopping malls, schools, music rooms, conference rooms, studios, recording studios, KTV rooms, bars, industrial plants, machine rooms, and home noise reduction, as well as other places with high requirements for acoustic environment and high-end decoration.
[0003] Sound-absorbing panels are widely used. Because the wall panels requiring installation are large, they are typically installed piece by piece, with the panels ultimately covering the entire wall. However, existing installation methods for sound-absorbing panels are cumbersome. The simple connection structure results in poor overall structural compactness during installation, failing to ensure tightness and reliability between panels, thus compromising construction quality. Therefore, it is necessary to propose an improvement to address these technical problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a quick-installation keel for bridge hole plates, solving the problems raised in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A quick-installation keel for a perforated plate includes a keel and a perforated plate. The bottom end of the keel is provided with a symmetrical T-shaped connecting part, and the top end of the keel is provided with a plurality of mounting holes. Fixing screws are provided in the mounting holes. The keel is fixed to the wall by the cooperation of the mounting holes and fixing screws. The interior of the keel is provided with symmetrical elastic blocks. The perforated plate is provided between the T-shaped connecting part and the elastic blocks. A retaining edge is provided on one side of the perforated plate.
[0007] Preferably, the keel is made of aluminum alloy and the outer side of the keel is coated with polytetrafluoroethylene.
[0008] Preferably, the inner wall of the keel is provided with sound insulation cotton.
[0009] Preferably, the keel has several through holes on both sides.
[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0011] The present invention provides a quick-installation keel for perforated plates. Using mounting holes and fixing screws, the keel is fixedly installed on the wall. One perforated plate is then snapped into the T-shaped connecting part at the bottom of the keel. An elastic block limits the position of the perforated plate, allowing the keel and perforated plate to be directly in contact, providing support and preventing damage. Simultaneously, a retaining edge on one side of the perforated plate allows the other perforated plate to be fixed to the keel, ensuring reliable and secure installation between the two plates. When one perforated plate needs to be replaced, it is not necessary to disassemble any other plate; simply press the elastic block and move the perforated plate away from the T-shaped connecting part for quick replacement, thus improving installation efficiency.
[0012] This utility model uses an aluminum alloy keel, and the outside of the keel is coated with a polytetrafluoroethylene coating. The polytetrafluoroethylene can enhance the corrosion resistance and aging resistance of the keel, thereby greatly improving the service life of the keel.
[0013] This utility model improves the sound absorption and noise reduction effect by installing sound insulation cotton on the inner wall of the keel and using the sound insulation cotton in conjunction with the bridge hole plate to isolate and absorb noise generated on the other side of the wall.
[0014] This invention features several through holes on both sides of the keel, allowing air to enter the cavity through one through hole and flow out through the other, creating a breathing effect. This helps to remove moisture from the cavity, keeping it dry and further extending the service life of the keel and the bridge plate. Attached Figure Description

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0020] According to an embodiment of the present invention, a quick-installation keel for a bridge hole plate is provided.
[0021] Example 1:
[0022] As shown in the attached diagram of the instruction manual. Figure 1 As shown, a quick-installation keel for a bridge hole plate includes a keel 1 and a bridge hole plate 8. The bottom end of the keel 1 is provided with a symmetrical T-shaped connecting part 2, and the top end of the keel 1 is provided with a plurality of mounting holes 3. Fixing screws 4 are provided in the mounting holes 3. The keel 1 is fixed to the wall 5 by the cooperation of the mounting holes 3 and the fixing screws 4. The interior of the keel 1 is provided with symmetrical elastic blocks 10. The bridge hole plate 8 is provided between the T-shaped connecting part 2 and the elastic block 10. A retaining edge 9 is provided on one side of the bridge hole plate 8.
[0023] Example 2:
[0024] As shown in the attached diagram of the instruction manual. Figure 1 , Figure 2 and Figure 3 As shown, a quick-installation keel for a perforated plate is first used with mounting holes 3 and fixing screws 4 to fix the keel 1 to the wall 5. Then, one of the perforated plates 8 is clamped onto the T-shaped connecting part 2 at the bottom of the keel 1. The perforated plate 8 is then limited by the action of the elastic block 10. At this time, the keel 1 and the perforated plate 8 are directly attached, so that the keel 1 can provide support for the perforated plate 8, thereby preventing damage to the perforated plate 8. At the same time, since one side of the perforated plate 8 is provided with a retaining edge 9, the other perforated plate 8 can be fixed to the keel 1 through the retaining edge 9, thus ensuring the reliability and firmness of the installation connection between the two perforated plates 8. When it is necessary to replace one of the perforated plates 8, it is not necessary to disassemble any other one. Just squeeze the elastic block 10 and then move the perforated plate 8 away from the T-shaped connecting part 2 to quickly replace it, thereby improving installation efficiency.
[0025] The keel 1 is made of aluminum alloy and coated with polytetrafluoroethylene (PTFE) coating 1.1 on the outside. PTFE can enhance the corrosion resistance and aging resistance of the keel 1, thereby greatly improving the service life of the keel 1.
[0026] The sound insulation cotton 6 is installed on the inner wall of the keel 1. The sound insulation cotton 6 and the bridge plate 8 work together to isolate and absorb the noise generated on the other side of the wall 5, thereby improving the sound absorption and noise reduction effect.
[0027] By providing several through holes 7 on both sides of the keel 1, air can enter the cavity through the through hole 7 on one side and flow out through the through hole 7 on the other side, forming a breathing effect. This helps to remove moisture from the cavity, keep it dry, and further extend the service life of the keel 1 and the bridge hole plate 8.
