Description

Technical Field

[0001] This utility model belongs to the field of building wall panel technology, and in particular relates to an EPS sound insulation and heat preservation wall panel. Background Technology

[0002] EPS is mainly used as a lightweight filler core material in soundproof wall panels. Its main advantages are: 1) significantly reducing the wall load (density is only 10-30kg / m³); 2) assisting in the absorption of mid-to-high frequency sound waves (sound absorption coefficient 0.6-0.8); 3) blocking the transmission of sound bridges; 4) synergistically improving thermal insulation performance.

[0003] EPS and high surface density boards (such as gypsum board) form a multi-layer composite structure, which uses the mass law to improve sound insulation (surface density ↑6dB, sound insulation ↑6dB).

[0004] Soundproof wall panels are typically composed of a base plate, inner partitions, and decorative panels, with each panel bonded and fixed to the others. The lack of an overall connecting component makes the overall structural stability of the composite wall panel need to be improved. Therefore, there is a need for an EPS soundproof and heat-insulating wall panel that can connect the various components of the soundproof wall panel through connecting components, thereby improving the overall integrity of the soundproof wall panel and thus increasing the structural strength of the wall panel.

This achieves the purpose of connecting the various components of the sound insulation wall panel through connecting components, thereby improving the overall integrity of the sound insulation wall panel and thus improving the structural strength of the wall panel.

[0013] 2. This utility model uses the cooperation of protrusions and grooves to make the sound insulation board and EPS insulation board fit together, which improves the stability of the connection between the two and further improves the connection strength of the wall panel structure.

[0014] 3. By setting a concave surface, this utility model increases the contact area between the rectangular block and the structural adhesive layer, further improving the stability of the rectangular block in the rectangular groove cavity for bonding and fixing.

[0015] 4. By setting up a pad, this utility model protects the nut block from the inner wall of the nut block hole, thus preventing the latter from being squeezed and damaged when they are in direct contact.

[0026] Figure 1-4This invention illustrates an embodiment of an EPS sound-insulating and heat-insulating wall panel, comprising a base plate 1. A sound-insulating board 2, an EPS insulation board 3, and a decorative board 4 are sequentially arranged on the top of the base plate 1. A rectangular groove 7 is formed at the bottom of the decorative board 4. A rectangular block 8 is arranged inside the rectangular groove 7. A screw 9 is welded to the bottom of the rectangular block 8. A structural adhesive layer 10 is filled between the rectangular block 8 and the inner wall of the rectangular groove 7. Perforations 12 are formed at the top of both the EPS insulation board 3 and the sound-insulating board 2. A second structural adhesive layer 13 is filled between the screw 9 and the inner wall of the perforation 12. A nut block hole 14 is formed at the bottom of the base plate 1. The screw 9 has a nut block 15 threadedly connected to its surface. A pad 16 is fitted onto the surface of the screw 9. The pad 16 fits against the inner wall of the nut block hole 14. The pad 16 protects the nut block 15 from being squeezed and damaged when they are in direct contact. A sealing gasket 17 is attached between the screw 9 and the inner wall of the nut block hole 14. The sealing gasket 17 seals the inner cavity of the nut block hole 14, preventing external moisture from entering the nut block hole 14 and thus improving the overall sealing performance of the wall panel.

[0027] Working principle: When using this utility model, the user applies adhesive to the opposite sides of the EPS insulation board 3 and the sound insulation board 2 and moves them relative to each other, so that the protrusion 5 and the groove 6 engage. Then, a rectangular groove 7 is opened on the surface of the decorative wood board 4. Next, adhesive is applied to the bottom of the decorative wood board 4 and the rectangular block 8 is fixed in the inner cavity of the rectangular groove 7 through the structural adhesive layer 10. Then, adhesive is applied to the top of the substrate 1 and it is attached to the sound insulation board 2. Then, the screw 9 is inserted through the through hole 12 in the sound insulation board 2 and the EPS insulation board 3, and the screw is connected to the nut block 15. The screw 9 is tightened and squeezes the base plate 1, causing the base plate 1, sound insulation board 2, EPS insulation board 3 and decorative wood board 4 to come together. The structural adhesive layer 13 allows the screw 9 to be tightly connected to the inner wall of the perforation 12, further improving the reliability of the screw 9 in fixing the sound insulation board 2 and EPS insulation board 3. Then, the sealing gasket 17 seals the inner cavity of the nut block hole 14, realizing the connection between the various components of the sound insulation wall panel through the connecting components, thereby improving the overall integrity of the sound insulation wall panel and thus improving the strength of the wall panel structure.

[0028] In summary, this EPS sound insulation and heat preservation wall panel uses structural adhesive layer 10 to fix rectangular block 8 in the inner cavity of rectangular groove 7, and the tightening of nut block 15 and screw 9 to compress base plate 1, so that base plate 1, sound insulation board 2, EPS heat preservation board 3 and decorative wood board 4 can be brought together. This achieves the purpose of connecting the various components of the sound insulation wall panel through connecting components, thereby improving the overall integrity of the sound insulation wall panel and thus improving the structural strength of the wall panel.
