Abstract

A sound insulation mat for a sound insulation floor is suitable for being disposed between a floor and a cement layer, and includes a shock absorbing layer and a rigid layer. The shock-absorbing layer is disposed on the floor and is used to absorb vibration and block sound transmission and has elasticity. The shock-absorbing layer includes an attaching surface adapted to closely adhere to the floor. The rigid layer is disposed between the shock absorbing layer and the cement layer, and includes a contact surface adapted to contact the cement layer. The rigid layer is more rigid than the shock absorbing layer, and the contact surface remains flat after the cement layer is grouted. The shock-absorbing layer having elasticity is attached to the floor, and the rigid layer provided between the shock-absorbing layer and the cement layer provides good rigidity, achieving the effect of being able to be closely attached and avoiding large depressions.

Description

Sound insulation mat for sound insulation floor

The invention relates to a sound insulation structure, in particular to a sound insulation mat for a sound insulation floor.

Referring to FIG. 1, an existing sound insulation mat 13 is laid between a floor slab 11 and a cement layer 12. The existing sound insulation mat 13 is made of a foamed material, which has better elasticity and softer material, even if the floor 11 unevenness can also be adhered well to reduce the generation of gaps. However, due to the poor rigidity of the foamed material, the cement layer 12 is prone to depression due to being squeezed after grouting.

Referring to FIG. 2, when the existing sound insulation pad 13 is made of a material with high rigidity (such as rubber), although the existing sound insulation pad 13 has better rigidity, it can avoid a large amplitude after the cement layer 12 is grouted. Depression, but poor adhesion results in a gap with the floor 11, causing stress concentration and poor durability.

Therefore, the object of the present invention is to provide a sound insulation mat for a sound insulation floor which can be closely attached and can be prevented from being sunken.

Therefore, the sound insulation mat of the new sound insulation floor is suitable for being disposed between a floor and a cement layer, and includes a shock absorbing layer and a rigid layer. The shock-absorbing layer is disposed on the floor and is used to absorb vibration and block sound transmission and has elasticity. The shock-absorbing layer includes an attaching surface adapted to closely adhere to the floor. The rigid layer is disposed between the shock absorbing layer and the cement layer, and includes a contact surface adapted to contact the cement layer. The rigid layer is more rigid than the shock absorbing layer, and the contact surface remains flat after the cement layer is grouted.

The effect of the novel model is that the shock-absorbing layer with elasticity is attached to the floor, and the rigid layer provided between the shock-absorbing layer and the cement layer provides good rigidity, which can be closely attached and can avoid large The effect of the depression of the amplitude.

Referring to FIG. 3 and FIG. 4, an embodiment of the sound insulation pad of the novel sound insulation floor is suitable for being disposed between a floor 8 and a cement layer 9, and includes a shock absorbing layer 2, a rigid layer 3, and a bonding layer 4. .

The shock absorbing layer 2 is disposed on the floor slab 8 and is used to absorb vibration and block sound transmission and has elasticity. The shock absorbing layer 2 includes an attaching surface 21 adapted to closely adhere to the floor slab 8. It is worth mentioning that the shock-absorbing layer 2 is made of low-density polyethylene, and other materials with good elasticity and softness, such as EVA material, can also be selected, but not limited to this.

The rigid layer 3 is disposed between the shock absorbing layer 2 and the cement layer 9, and includes a contact surface 31 suitable for contacting the cement layer 9. The rigid layer 3 is more rigid than the shock absorbing layer 2. The cement layer 9 remains flat after grouting. In more detail, in this embodiment, the composition of the rigid layer 3 is composed of recycled tire fragments and foamed material particles, and may also be made entirely of rubber, or other materials having a rigidity greater than the shock-absorbing layer 2 may be used. This is the limit.

The bonding layer 4 is disposed between the shock absorbing layer 2 and the rigid layer 3. In this embodiment, the bonding layer 4 is double-sided tape. In other variations, other adhesives such as adhesive can be used to join the shock absorbing layer 2 And the equivalent components of the rigid layer 3 are not limited to this; it should be noted that, in other variations, the rigid layer 3 may be omitted and the rigid layer 3 may be directly laid on the shock-absorbing layer 2 on.

In actual use, the bonding layer 4 is used to bond the shock-absorbing layer 2 and the rigid layer 3, and then laid on the floor slab 8. Then, the cement mortar is poured on the rigid layer 3, and the cement mortar is left for a period of time. The cement layer 9 is solidified to complete the setting of the sound insulation pad.

Compared with the existing sound insulation pad, the elastic shock-absorbing layer 2 is provided on the floor plate 11, the attaching surface 21 is closely adhered to the floor plate 8, and the shock-absorbing layer 2 and the shock-absorbing layer 2 are provided. The rigid layer 3 between the cement layers 9 provides good rigidity, prevents the contact surface 31 from generating a large depression after the cement layer 9 is grouted, and achieves the effects of close adhesion and avoiding depression.

In summary, the sound insulation mat of the new sound insulation floor slab can indeed achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of implementation of the new model cannot be limited by this, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the new model and the content of the patent specification are still Within the scope of this new patent.
