Description

The structure of floor sound insulation layer cushion

This creation is about the structure of floor sound insulation layer pad, especially a kind of sound insulation layer pad structure that can prevent water and mud from penetrating into the sound insulation layer, and can directly mix cement mortar on the surface to ensure convenient construction and good sound insulation effect.

With the latest regulations on sound insulation in the Building Law, the sound insulation effect between the sub-floor slabs of the newly launched projects must be maintained at a preset value (58 decibels). In order to meet the above-mentioned sound insulation requirements Generally, sound-absorbing pads with sound-absorbing buffering effect are installed between the floors of the building, in order to achieve the preset noise reduction effect and meet the regulations.

In addition, due to the increasing height of various buildings, in order to save manpower and simplify the arrangement of hanging equipment, most of the current construction methods of floor slabs and sound insulation layer pads on each floor in buildings are to mix a sufficient amount of cement, sand and pads at one time. Materials such as sound insulation layer pads are transported to each floor and stacked at each predetermined position; after the sound insulation layer pads of the floor slabs are placed and fixed, cement and sand are mixed with water on site, and the mixed cement mortar Stacked on the sound insulation layer pad, in addition to pressing and fixing the sound insulation layer pad, it is also convenient for the subsequent application of the surface decoration layer (tiles or floor tiles) above.

In the new case of the Republic of China Patent Publication No. M588054, there is disclosed a rubber fiber sound insulation pad (board), which is made of a plurality of glass fibers, which are arranged in a staggered longitudinally interwoven with appropriate thickness and width. The blanket is impregnated with a rubber solvent and then dried to form; and a waterproof film can be coated on the surface of the sound insulation pad (board) to avoid water penetration.

However, in the above structure, since the waterproof membrane is directly coated on the surface of the sound insulation pad (board), and most waterproof membranes have waterproof properties, they are soft and cannot withstand pressure and friction. In order to avoid the above-mentioned mixed cement The operation of mortar damages the waterproof membrane, so that water or cement mortar penetrates into the sound insulation layer pad, and reduces the shock absorption and sound insulation effect of the sound insulation layer pad after drying and hardening; therefore, the above operation of mixing cement mortar cannot be directly applied to the sound insulation layer pad It must be carried out at other reserved sites, and then the mixed cement mortar is transported to the construction site and stacked on the sound insulation layer pad, which often causes inconvenience in construction, and the last construction on the same floor in the building. room or site, it may be necessary to wait for the cement mortar in other rooms or sites to dry before mixing the cement mortar, or mix the cement mortar on other floors and then transport it to the final construction room or site, which will seriously affect the construction efficiency.

In the new case of the Republic of China Patent Publication No. M613139, a sound insulation layer structure of a floor slab is disclosed, which is a sound insulation middle material covered by two-sided substrates, and a waterproof layer is arranged between the surface substrate and the sound insulation middle material The waterproof layer is made of environmentally friendly polyolefin, the surface substrate is polyester cotton or porous fiber cloth, and the capillary fibers on the surface can directly adhere and bite on the mixed soil, and the sound insulation middle material is porous fiber material or polyolefin foam (IXPE; EVA), which has porosity, which produces a noise reduction effect.

Although the above-mentioned structure can utilize the five-layer stacked structure to achieve the preset sound insulation and noise reduction and the effect of being easily combined with the concrete, the five-layer stacked structure not only greatly increases the production cost, but also causes The overall thickness increases, which affects the design of the floor thickness and is not conducive to the utilization of indoor space.

In view of the above-mentioned shortcomings of the conventional floor sound insulation layer cushion structure in practical application, the creator researched and improved the way of these shortcomings, and finally came up with this creation.

The filter layer 2 is arranged on at least one surface side of the sound insulation layer 1, and it can be a coating layer formed of polyethylene PE (or other materials with similar waterproof properties) (which can be coated by lamination), and its thickness is between 0.5 ~2mm (preferably 0.5mm); the filter layer 2 can form a water barrier effect on the surface of the sound insulation layer 1 to prevent external water or cement mortar from infiltrating the sound insulation layer 1 , causing the fibers in the sound insulation layer 1 to deteriorate or harden and block due to the drying of the cement slurry, thereby affecting the sound insulation and noise reduction effect of the sound insulation layer 1 .

The interface layer 3 is arranged on the side of the filter layer 2 away from the sound insulation layer 1 in combination, and it can be a coating layer formed of polyester fiber (eg, polyethylene terephthalate PET). between 0.5~2mm (preferably 0.5mm); because the interface layer 3 has tough and elastic material properties, it can not only form a shielding protection mechanism for the filter layer 2, but also avoid the filter layer 2. Wear and tear caused by external force or improper collision during construction; at the same time, the interface layer 3 also has the characteristics of being easy to combine with the filter layer 2 and cement mortar and cement mortar.
