Description

Technical Field

[0001] The invention belongs to the technical field of indoor acoustic effects, and in particular relates to a sound-reflecting plate structure for an indoor ceiling and a mounting method thereof. Background Art

[0002] In recent years, with the continuous improvement of people's music appreciation ability and the continuous pursuit of pure natural sound environment, the original electronic sound amplification and sound transmission system can no longer meet people's needs. Instead, it is replaced by sound-reflecting panels arranged on the indoor ceilings of theaters and concert halls. However, traditional sound-reflecting panels are mostly composed of multiple acrylic panels, and there are gaps between the panels. This shape will form many small sound-reflecting surfaces, resulting in low acoustic efficiency, unable to ensure that the auditorium has sufficient sound field strength, and relatively large absorption of low frequencies, thereby reducing the reverberation time and sound surround in the auditorium, unable to achieve a pure natural sound environment, and unable to enable the audience to obtain early reflected sound. Moreover, the sound-reflecting panel will reflect the original path of the sound wave back after the sound wave is transmitted, so it is impossible to achieve a balance between the early reflected sound and the late reflected sound, so that the acoustic surround of each seat is poor, resulting in a very poor audience experience; therefore, we propose a sound-reflecting panel structure for indoor ceilings and its installation method to solve the above problems. Summary of the invention

[0037] In order to solve the problem that the auditorium sound field is insufficient and has a relatively large absorption of low frequencies, thereby reducing the reverberation time and sound surround in the auditorium, failing to achieve a pure natural sound environment, failing to enable the audience to obtain early reflected sound, and failing to achieve a balance between early reflected sound and late reflected sound, resulting in a poor acoustic surround for each seat and a very poor audience experience, the present invention provides a sound-reflecting board structure for indoor ceilings and an installation method thereof. The following is a further description of the sound-reflecting board structure for indoor ceilings and an installation method thereof with specific embodiments and accompanying drawings.

[0038] See also Figures 1 to 8 As shown, a sound-reflecting board structure for indoor ceilings comprises:

[0039] Frame 2, fixed below the indoor ceiling through a suspension assembly;

[0040] A top plate 6 is fixed to the upper portion of the frame 2, and an edge thereof extends out of the frame 2 to form a first overlapping edge;

[0041] The spherical panel is suspended from the lower part of the frame 2, and the edge of the spherical panel is bent inwardly at the outer periphery of the frame 2 to form a second overlapping edge, and the first overlapping edge and the second overlapping edge form an overlapping seam 19. The surface of the spherical panel is shaped like a water ripple mechanism, which is used to reflect the transmitted sound waves and diffuse them in a divergent shape; and

[0042] The first filler is filled in the overlap seam 19 so that the spherical panel and the top plate 6 cooperate to wrap the frame 2; the spherical panel, the top plate 6 and the first filler are all made of GRG material.

[0043] Through the special curved shape of the annular sound reflector and the water ripple mechanism on its surface, after the early sound waves are transmitted, its design will effectively change the reflection direction of the sound waves. It will no longer return along the traditional single original path, but will form a more divergent effect. This will minimize the impact on the later reflected sound, and can form a better resonance with the later reflected sound in all directions, forming a more balanced acoustic effect.

[0044] Among them, see Figure 1 and Figure 3 As shown, the spherical panel includes four curved panels 5 enclosing a spherical surface, and the frame 2 includes a main frame and four hoisting keel groups fixed to the bottom of the main frame and corresponding to the four curved panels 5 respectively;

[0045] The frame 2 also includes four first fixing components for connecting and fixing the four lifting keel groups to the corresponding curved panels 5 respectively;

[0046] The adjacent curved panels 5 are filled with a second filler, which is made of GRG material;

[0047] See also Figure 1 As shown, each lifting keel group includes at least one lifting keel 4, and each first fixing assembly includes at least one first bolt 14, at least one first screw hole respectively penetrating at least one lifting keel 4, at least one connecting member 11 fixed to a side of the curved panel 5 facing the lifting keel 4, and at least one second screw hole respectively penetrating at least one connecting member 11;

[0048] The first bolt 14 connects the first screw hole / the second screw hole and the second screw hole / the first screw hole in series to fix the connecting member 11 to the corresponding hoisting keel 4 .

[0049] Specifically, in this embodiment, refer to Figure 3 As shown, the number of hoisting keels 4 in each hoisting keel group is three, and the three hoisting keels 4 are arranged at intervals from the center of the frame 2 to the edge of the frame 2, and each first fixing assembly includes three first bolts 14, three first screw holes, three connecting members 11 and three second screw holes. By arranging multiple hoisting keels 4 and connecting members 11 to be connected and fixed, the stability of the connection between the curved panel 5 and the frame 2 can be greatly improved;

[0050] Further, see Figure 4As shown, a joint seam 15 is formed between adjacent curved panels 5, and a second filler is filled in the joint seam 15; the second filler includes a fifth caulking material filled in one end of the joint seam 15 toward the frame 2, a third anti-cracking mesh cloth laid on the side of the fifth caulking material away from the frame 2, and a sixth caulking material laid on the third anti-cracking mesh cloth and filled in the other end of the joint seam 15, the outer surface of the sixth caulking material has the same curvature as the outer surface of the curved panel 5, and by filling the joint seam 15 between the curved panels 5, the loss of sound through the joint seam 15 and its absorption can be greatly reduced, and the provision of the anti-cracking mesh cloth can improve the toughness and life of the second filler, thereby improving the service life of the sound-reflecting board, and by the second filler being made of GRG material, the second filler can have good sound wave reflection performance like the curved panel 5.

[0051] Among them, see Figure 8 As shown, four curved panels 5 are arranged opposite to each other in pairs, and a docking plate 23 is connected to the lower part of each curved panel 5 and one side facing the frame 2;

[0053] All the butt joint plates 23 enclose a through opening 24 , and the through opening 24 is filled with a third filler made of GRG material.

[0054] Specifically, the number of the second fixing components is two, each of which includes a second bolt 21, a third screw hole penetrating one of the two opposite butt joint plates 23, and a fourth screw hole penetrating the other of the two opposite butt joint plates 23. The second bolt 21 passes through the third screw hole / fourth screw hole and the fourth screw hole / third screw hole in sequence to connect and fix the two opposite butt joint plates 23, thereby improving the integrity of the ball panel.

[0055] Furthermore, the anti-sound board structure also includes a cover 17 for wrapping one end of all the docking plates 23 facing the frame 2, and the cover 17 is made of GRG material; the third filling material includes a third caulking material 16 filled in the end of the opening 24 facing the frame 2, a second anti-crack mesh cloth 18 laid on the side of the third caulking material 16 away from the frame 2, and a fourth caulking material laid on the second anti-crack mesh cloth 18 and filled in the other end of the opening 24, and the outer surface of the fourth caulking material has the same curvature as the outer surface of the curved panel 5; by blocking the opening 24, the absorption of low-frequency sound waves can be reduced, so that the transmitted sound waves can be better diverged, avoiding the traditional single original path return.

[0058] Further, see Figure 2 As shown, the frame 2 is formed by splicing three horizontal bars and three vertical bars. Figure 2 As shown, reinforcing keels 3 are installed on the periphery to ensure the overall strength of the frame 2.

[0059] Among them, the first filling material includes a first caulking material filled in one end of the lap joint 19 toward the frame 2, a first anti-crack mesh cloth laid on the side of the first caulking material away from the frame 2, and a second caulking material laid on the first anti-crack mesh cloth and filled in the other end of the lap joint 19, and the top of the second caulking material is flush with the top surface of the top plate 6.

[0060] Specifically, the top plate 6 is formed by splicing a plurality of plates, and a fourth filler is filled in the gap, and the fourth filler is consistent with the structural material of the first filler; the surface of the top plate 6 is a smooth flat plate; the thickness of the top plate 6 and the curved plate 5 is 40 mm, and the water ripple mechanism shape of the surface of the curved plate 5 is 0-10 mm.
