[0027] The hard board layer 110 is made of a polystyrene foam board, and the sound insulation layer 130 is made of a polyurethane sound insulation foam layer.

[0028] The aerogel felt layer 120 is fixed to the sound insulation layer 130 by an adhesive. The lower surface of the aerogel felt layer 120 completely covers the upper surface of the sound insulation layer 130. That is, the aerogel felt layer 120 is completely aligned with the sound insulation layer 130. The hard board layer 110 is fixed to the upper surface of the aerogel felt layer 120 by an adhesive. The four sides of the hard board layer 110 are parallel to the four sides of the aerogel felt layer 120. Only one side of the hard board layer 110 extends out of the upper surface of the aerogel felt layer 120. The extended portion is recorded as area A140. The aerogel felt layer 120 The portion of the upper surface not covered by the hard board layer 110 is recorded as area B150.

A wedge block 160 is fixed on the side of the hard board layer 110 extending out of the upper surface of the aerogel felt layer 120, and a wedge-shaped groove 170 is opened on the side of the hard board layer 110 opposite to the wedge block 160, and there is a set of wedge block 160 and wedge groove 170.

[0029] The two splicing unit blocks 100 are spliced ​​in the following manner: the wedge block 160 of one splicing unit block 100 is inserted into the wedge groove 170 of the other splicing unit block 100, and the part of the hard board layer 110 extending from one splicing unit block 100, namely area A140, is fixed to the aerogel felt layer 120 of the other splicing unit block 100, namely area B150, by adhesive.

[0030] In this embodiment, a group of wedge blocks 160 and wedge-shaped grooves 170 are used to achieve continuous splicing of several splicing unit blocks 100 in the same direction. One side of the hard board layer 110 extends out of the upper surface of the aerogel felt layer 120, and the portion of the hard board layer 110 extending from one splicing unit block 100 is fixed to the aerogel felt layer 120 of another splicing unit block 100 by adhesive, thereby increasing the fixing area between adjacent splicing unit blocks 100 and achieving a fixed connection between adjacent splicing unit blocks 100. The splicing position is highly stable, the splicing is neat, and it is not easy to deform.

[0031] Furthermore, the wedge block 160 and the wedge-shaped groove 170 are both in the shape of long strips.

[0032] refer to Figure 3 In order to maintain the neatness of the splicing, the splicing unit blocks 100 on both sides can remove the wedge blocks 160 and the area A 140 , or remove the wedge grooves 170 and the area B 150 as needed.

[0033] refer to Figure 5The sound insulation layer 130 includes a sound insulation upper layer 131 and a sound insulation lower layer 132. The sound insulation upper layer 131 includes a first foam layer 1311 and a plurality of first foam strips 1312. The first foam layer 1311 is fixed under the aerogel felt layer 120. The plurality of first foam strips 1312 are fixed at equal intervals under the first foam layer 1311. The sound insulation lower layer 132 includes a second foam layer 1321 and a plurality of second foam strips 1322. The plurality of second foam strips 1322 are fixed at equal intervals on the second foam layer 1321. The second foam strips 1322 are inserted between the two first foam strips 1312, and the first foam strips 1312 are inserted between the two second foam strips 1322.

[0034] Furthermore, a first receiving groove 1313 for inserting the second foam strip 1322 is provided between two adjacent first foam strips 1312, the second foam strip 1322 is fixed in the first receiving groove 1313 by an adhesive, and a first gap 1314 is left between the top surface of the second foam strip 1322 and the bottom wall of the first receiving groove 1313, and a second receiving groove 1323 for inserting the first foam strip 1312 is provided between two adjacent second foam strips 1322, the first foam strip 1312 is fixed in the second receiving groove 1323 by an adhesive, and a second gap 1324 is left between the top surface of the first foam strip 1312 and the bottom wall of the second receiving groove 1323.

[0035] Furthermore, the thickness of the first foam layer 1311 is greater than the thickness of the second foam layer 1321 .

[0036] The sound insulation layer 130 achieves sound insulation effect through its internal porous material structure. When the sound insulation and heat preservation cotton structure is attached to the wall or the floor, the sound insulation and heat preservation cotton structure is sometimes squeezed. Long-term squeezing or high-intensity squeezing may cause the sound insulation layer 130 to collapse, and its internal pores are squeezed, affecting the sound insulation effect. Therefore, a gap is left between the sound insulation upper layer 131 and the sound insulation lower layer 132 to give the sound insulation layer 130 sufficient accommodation space, minimize squeezing, and maintain a long-term sound insulation effect.

There are two groups of wedge blocks 160 and wedge grooves 170, and the wedge blocks 160 of one splicing unit block 100 are inserted into the wedge-shaped grooves 170 of another splicing unit block 100. The part of the hard plate layer 110 extending out of one splicing unit block 100 is fixed to the aerogel felt layer 120 of the other splicing unit block 100 by adhesive.

[0040] In this embodiment, two groups of wedge blocks 160 and wedge-shaped grooves 170 are used to achieve continuous splicing of several splicing unit blocks 100 in both length and width directions.
