Description

Interlayer noise reduction material of building {Plate for sound insulation}

The present invention relates to a floor noise reduction material of a building, and more particularly, to a floor noise reduction material of a building which is constructed between floors of a building to completely block noise generated between floors, thereby improving customer satisfaction. It is about.

In general, the impact sound that is applied to the building structure of apartment houses such as apartments and villas is transmitted to all directions of solid sound generated by people walking, opening and closing of doors, moving objects, starting or stopping equipment, etc. This causes the surface of the building structure to vibrate, as well as being switched to airborne sound, which is perceived as noise when it is heard by people around.

For example, the impact of falling objects on the floor or the sound of moving chairs generates solid sound, which is transmitted through the floor slab and the walls to other adjacent rooms, especially the floor slab. Passed through the lower floor is called interlayer noise.

Nowadays, the problem of floor noise has become serious in apartments, and the regulations on housing construction standards have been strengthened and revised.

The regulations stipulate that the floor impact sound between floors should be less than 58 decibels (dB) and the weight impact sound should be less than 50 decibels (dB) or standard floor structure as determined and announced by the Minister of Construction and Transportation.

As such, conventional interlayer floor structures are proposed for minimizing and minimizing seriously reduced floor noise. Such conventional interlayer floor structures are based on the concrete slab 1, as shown in FIG. Lightweight foam concrete layer (2) is formed on the upper part, heating pipe (3) and finishing mortar layer (4) is formed on the upper part, and the floor decorative layer made of decorative materials such as monolium, solid wood, tiles, etc. 5) consists of.

In the interlayer floor structure of the above structure, the lightweight foamed concrete layer 2 formed on the concrete slab 1 is responsible for attenuating the impact sound or noise, but the effect is insignificant.

For this reason, in order to more effectively block noise and impact, a construction method for forming an interlayer shock-absorbing material between the concrete slab and lightweight foamed concrete is disclosed.

The conventional interlayer shock sound absorbing material 10 is provided as various structures, and typically has hard styrofoam materials 11 and 12 having a predetermined thickness in the upper and lower portions, as shown in FIG. The intermediate sound insulation material 3 of the polyester material with a large gap is sandwiched in the form of a sandwich.

Therefore, the middle sound insulating material 13, together with the upper and lower styrofoam materials 11 and 12, absorbs shocks and vibrations, thereby reducing interlayer noise.

However, the conventional interlayer impact sound absorbing material described above has a problem in that the upper styrofoam, the intermediate sound insulation material, and the lower styrofoam material are laminated, and the thickness thereof is difficult, resulting in a large construction cost.

Accordingly, the applicant of the present invention, in view of the problems described above, the application for the 'interlayer noise reduction material of the building' to reduce the construction cost by the ease of construction, because the thickness is thin, easy construction, application (application number No. 10-2005-114872) has been registered (registration number 10-718701).

The registered patent 'interlayer noise reduction material of the building' is as shown in Figures 3 and 4, the upper member 22 of the moisture-proof function made of polyethylene or PVC material; An intermediate member 24 made of a polyester material and stacked below the upper member; It is laminated under the intermediate member, and is made of foamed polystyrene or foamed polypropylene, the bottom of which is a lower member 26 in which the convex portion 26a and the concave portion 26b in a linear direction are sequentially formed in sequence. Characterized in that the made up.

Therefore, the interlayer noise reduction material of the above-mentioned structure is made of a structure that is simple and easy to manufacture, thereby improving productivity, and as a whole, the thickness thereof is thin and easy to construct, thereby improving workability. Of course, construction costs will be reduced.

In addition, while the shock absorbing structure is made of a triple structure, in the final three step is made of a structure that absorbs the shock even more by a separate elasticity, it is possible to have a further improved effect of reducing the interlayer noise.

However, the above-described 'layer noise reduction material of the building' has many advantages as compared to the prior art as described above, but the intermediate member applied in the middle to absorb the secondary shock is made of a polyester material, There was a problem that the function of shock absorption is not properly exhibited.
