[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to solve the technical problem of how to adjust the thickness of the sound insulation board by stretching and contracting, please refer to Figure 1-Figure 5 , this embodiment provides the following technical solutions:

[0024] A sound insulation board for construction includes a board body 1, which is composed of a main board 11 and a sub-board 12. A fixing frame 111 is welded to the side end of the main board 11, and a fixing plate 121 is welded to the side end of the sub-board 12 symmetrically in the upper and lower directions. A first slide groove 112 for sliding the fixing plate 121 is provided in the fixing frame 111. The fixing plate 121 is fixed to the fixing frame 111 by a positioning bolt 15. The positioning bolt 15 is detachably connected to the fixing frame 111. A positioning hole 123 adapted to the positioning bolt 15 is provided on the fixing plate 121.

[0025] The fixed frame 111 is symmetrically provided with second slide grooves 113 at the upper and lower ends of the first slide groove 112, and the upper and lower ends of the fixed plate 121 are symmetrically welded with limit blocks 122. The limit blocks 122 form a sliding connection with the second slide groove 113, and the length of the second slide groove 113 is less than that of the first slide groove 112.

[0026] Among them, the design of the second slide groove 113 and the limit block 122 provides precise limit for the sliding of the sub-plate 12 in the main plate 11. Since the limit block 122 can only move in the second slide groove 113, and since the length of the second slide groove 113 is less than the length of the first slide groove 112, the sub-plate 12 can only move within a predetermined range, which can prevent the sub-plate 12 from slipping out of the main plate 11.

[0027] Specifically, use an appropriate tool to loosen the positioning bolts 15 to release the fixed state between the fixing plate 121 and the fixing frame 111, so that the fixing plate 121 can slide in the first sliding groove 112, and then manually move the sub-plate 12 gently until the sub-plate 12 moves to the desired position, and then re-insert the positioning bolts 15 through the positioning holes 123 on the fixing plate 121 and connect it to the fixing frame 111 to complete the adjustment of the thickness of the sound insulation board.

[0028] To solve the technical problem of how to increase the sound insulation effect of sound insulation board by thickness, please refer to Figure 2 and Figure 4 , this embodiment provides the following technical solutions:

[0029] Foam boards 3 can be inserted into the fixing frame 111 and the fixing plate 121 through the slots 14, and sound insulation cotton 4 can be clamped between adjacent foam boards 3 and between the foam board 3 and the fixing frame 111 or the fixing plate 121. Sound insulation felt 31 is bonded to the left and right ends of the foam board 3.

[0030] Specifically, by adjusting the position of the sub-plate 12, the overall thickness of the sound insulation board can be changed, and the increase in thickness means an increase in the number of slots 14, that is, the number of foam boards 3 that can be plugged into the slots 14 will also increase, and accordingly the number of sound insulation cotton 4 will also increase, forming a multi-layer sound insulation structure, increasing the path for sound wave propagation, so that the foam boards 3 and sound insulation cotton 4 can better absorb and block sound waves, reducing the transmission of noise.

[0031] The foam board 3 itself has a certain sound insulation performance, and sound insulation cotton 4 can be engaged between adjacent foam boards 3 and between the foam board 3 and the fixing frame 111 or the fixing board 121, further enhancing the sound insulation effect. At the same time, sound insulation felt 31 is bonded to the left and right ends of the foam board 3. The sound insulation felt 31 is a highly efficient sound insulation material that can absorb sound wave energy and reduce the reflection and propagation of sound waves, and is particularly effective in sound insulation of high-frequency noise.

[0032] Therefore, through the above-mentioned multi-layer sound insulation structure, thickness adjustment and application of the sound insulation felt 31, the sound insulation board can provide different sound insulation effects under different thickness conditions.

[0033] Among them, the outer ends of the main board 11 and the sub-board 12 are both protruding with flanges 13, and the side end plates 2 are detachably installed between adjacent flanges 13 by bolts. The design of the side end plates 2 provides additional structural support for the sound insulation board, enhances the overall stability and rigidity of the sound insulation board, and at the same time helps to seal the edges of the sound insulation board to form a closed sound insulation space, prevent sound waves from leaking from the edges of the sound insulation board, and improve the sound insulation effect.

[0034] Working principle: When the sound insulation effect of the sound insulation board for this building needs to be increased, use a tool to loosen the positioning bolt 15 to make the fixing plate 121 slide in the first slide groove 112, manually pull the sub-plate 12 outward until the sub-plate 12 moves to the required position, insert the positioning bolt 15 into the positioning hole 123 and connect it to the fixing frame 111 to increase the thickness of the sound insulation board. At this time, the slot 14 is increased, and the foam board 3 is inserted into the newly added slot 14, and then sound insulation cotton 4 is installed between the newly added foam boards 3, so that the number of foam boards 3 and sound insulation cotton 4 is increased, thereby forming a multi-layer sound insulation structure to increase the sound insulation effect.
