Description

Technical Field

[0001] This utility model belongs to the technical field of noise control equipment, specifically relating to a frame-plate snap-fit ​​sound barrier with high compressive strength. Background Technology

[0002] A sound barrier is a specially designed acoustic barrier placed between a noise source and a receiving point. It is usually designed for a specific sound source and a specific protected location (or area). A sound barrier is mainly composed of an outer shell and an inner sound-absorbing and insulating panel. The outer shell is mainly composed of a front panel and a back panel. In existing sound barriers, the outer shell is generally formed by fastening the front panel and the back panel together. However, due to the low structural strength of the front panel and the back panel, the front panel and the back frame are prone to deformation during use, and the middle of the front panel and the back panel is also prone to inward deformation, which affects the fixation of the inner sound-absorbing and insulating panel, causing the sound-absorbing and insulating panel to collapse and lose its sound absorption and insulation function. Utility Model Content

[0003] Technical Problem: In view of the above-mentioned problems existing in the prior art, the technical problem to be solved by this utility model is to provide a frame-plate interlocking sound barrier with high compressive strength to improve the structural strength of the sound barrier.

[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A high-compression-strength frame-plate snap-fit ​​sound barrier includes a panel, a back panel snap-fitted to the panel, a sound-absorbing panel disposed between the panel and the back panel, and a frame plate detachably connected to the panel and the back panel. The back of the panel is provided with a first left side panel and a first right side panel, and the front of the back panel is provided with a second left side panel corresponding to the first left side panel and a second right side panel corresponding to the first right side panel. When the panel and the back panel are snapped together, the second left side panel and the second right side panel are located between the first left side panel and the first right side panel, forming a receiving space between the panel and the back panel to accommodate the sound-absorbing panel. The frame plate is supported between the panel and the back panel and closes the receiving space.

[0006] Preferably, the frame includes two U-shaped plates that enclose the accommodating space from the top and bottom.

[0007] Preferably, the back panel has a first sliding groove on both sides, and the back plate has a second sliding groove corresponding to the first sliding groove. The U-shaped plate includes a horizontal plate and two vertical plates, and the vertical plates are inserted into the first sliding groove and the corresponding second sliding groove.

[0008] Preferably, both the first left side plate and the first right side plate are provided with multiple threaded holes, and the vertical plate is provided with through holes corresponding to the threaded holes. A fixing bolt passes through the through hole, and the vertical plate is connected to the first left side plate and the first right side plate by the fixing bolt.

[0009] Preferably, both the second left side plate and the second right side plate are provided with end vertical supports for fixing the sound-absorbing plate, and the end vertical supports are provided with first slots for engaging the sound-absorbing plate.

[0010] Preferably, the accommodating space is provided with a central vertical support for fixing the sound-absorbing panel. The central vertical support can be movably connected to both the front panel and the back panel. The central vertical support is symmetrically provided with two second slots for engaging the sound-absorbing panel.

[0011] Preferably, the cross plate is a corrugated bent plate.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0013] 1. The frame is composed of two U-shaped plates. The U-shaped plates are inserted into the front and back panels from the top and bottom ends, forming support for the front and back panels at the edge of the sound barrier, thereby improving the overall structural strength of the sound barrier.

[0014] 2. Set corresponding side panels on the front panel and back panel. The front panel and back panel are fastened together by the elastic pre-tightening force between the side panels. The side panels, together with the vertical plates of the U-shaped plate, form three supports at the side, which improves the compressive strength of the side of the sound barrier.

[0015] 3. By setting end vertical supports and middle vertical supports, the sound-absorbing panels can be effectively fixed. The middle vertical supports can provide support for the middle position of the front panel and the back panel, thereby improving the compressive strength of the middle position of the front panel and the back panel.

[0016] 4. The horizontal plate of the U-shaped plate is made of corrugated bending plate, which supports the front and back plates on both sides of the sound barrier, greatly improving the compressive strength of the top and bottom sides of the sound barrier. Attached Figure Description

These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0028] like Figure 1 and Figure 4 As shown, a high compressive strength frame-plate snap-fit ​​sound barrier includes a panel 1, a back panel 2, a sound-absorbing panel 3, and a frame 4. In use, the back of the panel 1 is snapped onto the front of the back panel 2, forming a receiving space between the panel 1 and the back panel 2 to accommodate the sound-absorbing panel 3. The frame 4 includes two U-shaped plates, which are inserted from the top and bottom ends between the panel 1 and the back panel 2 to seal the receiving space. The middle part of the panel 1 is provided with a perforated area 14, in which multiple round holes are arranged in an array.

[0029] like Figure 1 , Figure 5 and Figure 6 As shown, the back of panel 1 is provided with a first left side plate 11 and a first right side plate 12. The first left side plate 11 and the first right side plate 12 are inclined inward at a certain angle, and when they expand outward, they form an inward elastic pre-tightening force. The front of back panel 2 is provided with a second left side plate 21 and a second right side plate 22. The second left side plate 21 corresponds to the first left side plate 11, and the second right side plate 22 corresponds to the first right side plate 12. When panel 1 and back panel 2 are fastened together, the second left side plate 21 and the second right side plate 22 are located between the first left side plate 11 and the first right side plate 12 and open the first left side plate 11 and the first right side plate 12. The first left side plate 11 is clamped to the second left side plate 21 by the elastic pre-tightening force, and the first right side plate 12 is clamped to the second right side plate 22 by the elastic pre-tightening force.

[0030] like Figure 1 , Figure 2 and Figure 3As shown, both the second left side plate 21 and the second right side plate 22 are provided with end vertical supports 61 for fixing the sound-absorbing panel 3. The end vertical supports 61 are connected to the second left side plate 21 and the second right side plate 22 by adhesive or rivets. The end vertical supports 61 are provided with a first slot 611. The size of the first slot 611 corresponds to the thickness of the sound-absorbing panel 3 and can be engaged with the sound-absorbing panel 3. A middle vertical support 62 is provided in the middle of the accommodating space. The main body of the middle vertical support 62 is made of H-shaped aluminum material. The middle vertical support 62 is symmetrically provided with a second vertical support at both ends. The second slot 621 is sized to correspond to the thickness of the sound-absorbing panel 3 and can be engaged with the sound-absorbing panel 3 to fix the sound-absorbing panel 3 together with the end vertical support 61. The middle vertical support 62 has connecting strips 622 on both sides. The panel 1 has a first middle groove 15 corresponding to the connecting strip 622, and the back panel 2 has a second middle groove 25 corresponding to the connecting strip 622. The connecting strip 622 is slidably connected to the two middle grooves. The middle vertical support 62 is slidably connected to the panel 1 and the back panel 2 for easy installation.

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the U-shaped plate includes a horizontal plate 41 and two vertical plates 42. The back side of the panel 1 has a first sliding groove 13 on both sides, which is vertically oriented. The back plate 2 has a second sliding groove 23 corresponding to the first sliding groove 13, which is also vertically oriented. When the two U-shaped plates are inserted between the panel 1 and the back plate 2 from the top and bottom, the two sides of the vertical plates 42 are respectively inserted into the corresponding first sliding groove 13 and the corresponding second sliding groove 23. After the two U-shaped plates are inserted between the panel 1 and the back plate 2 from the top and bottom, the horizontal plate 41 is flush with the top and bottom ends of the panel 1 and the back plate 2. The lower end of the vertical plate 42 of the upper U-shaped plate is aligned and in contact with the upper end of the vertical plate 42 of the lower U-shaped plate, thus the two U-shaped plates close the receiving space from all four sides. Both the first left side panel 11 and the first right side panel 12 are provided with multiple threaded holes 51, which are vertically spaced. The vertical plates 42 of the two U-shaped plates are provided with through holes 52 corresponding to the threaded holes 51, and fixing bolts 53 pass through the through holes 52. When the U-shaped plates are inserted between the front panel 1 and the back panel 2, the vertical plates 42 are connected to the first left side panel 11 and the first right side panel 12 through the fixing bolts 53, thereby securing the two U-shaped plates. This forms three supports on each side of the sound barrier with the two left side panels and the two right side panels, improving the compressive strength of the two sides of the sound barrier. To improve the compressive strength of the sound barrier frame, the horizontal plate 41 is a corrugated bent plate. When the U-shaped plates are inserted, the horizontal plate 41 is supported between the front panel 1 and the back panel 2, forming stable support for the upper and lower horizontal edges of the sound barrier in the lateral direction, greatly improving the compressive strength.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
