Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring material having acoustically excellent sound insulation properties and vibration isolation properties.

[0002]

2. Description of the Related Art In recent years, the number of buildings having a multi-layer structure has been increasing in urban areas for the purpose of securing a living space, but as the living space is integrated, troubles with noises with neighboring residents are also increasing. In the past, in order to reduce floor impact noise, mainly in offices, schools, and large-scale apartments, floating floors with cushioning materials inserted between floor structures and floor finishing materials were sometimes constructed.

An example of the above conventional floor structure will be described below with reference to the drawings. FIG. 6 is a sectional view of a conventional floating floor structure. In order to reduce the transmission of vibration, the concrete slab 19 and the floor structure 2 under the floor finishing material 18
By constructing a structure in which the plywood 20 and the cushioning material 21 are inserted between the two, a floating floor that reduces the floor impact sound is realized.

[0004]

However, the above-mentioned conventional floating floor has the following problems. In other words, when the floating floor is used as a renovation work, a large amount of work is required for both the amount and the period, and a great mental and physical burden is imposed not only on the resident but also the residents in the vicinity during the construction. Therefore, in practice, the conventional floating floor described above can only be performed when a building is constructed. However, current living styles vary widely depending on the resident, and even if you look at one resident, the problem that the performance prepared at the time of occupancy is either excessive or insufficient is an individual problem. It was happening. In addition, the vibration transmission was reduced in the vertical direction by the cushioning material, but in the horizontal direction, the vibration was not expected to be reduced because the concrete slab under the floor finishing material was a single plate. . In addition, it was difficult to make the performance uniform because the sound insulation and anti-vibration properties depend on the construction conditions. Furthermore, since the concrete slab has a structure that floats above the cushioning material, the floor surface may tilt due to uneven loading.

In view of the above problems, it is an object of the present invention to provide a floor material which can be easily assembled and disassembled and which can quickly construct a floor surface having high sound insulation performance.

[0006]

In order to achieve the above object, the flooring material of the present invention has a multilayer structure of a concrete slab having a cork sheet laid inside, a porous cushioning material and a floor substrate, and other flooring materials. It is characterized in that a cushioning material is attached to the joint surface at the time of connecting with, and vibration transmission between the floor surface and the floor material installation surface is reduced. Further, the flooring material of the present invention is characterized in that the flooring board is provided with a supporting means for the flooring board provided with a vibration-proof material at the tip and an adjusting means for adjusting the height.

[0007]

According to the present invention, in order to connect a plurality of floor materials with only the concrete slab, the present invention is arranged so that the projections and the notches of the concrete slab are engaged with each other, and these parts are connected with screws. This constitutes the floor surface. At this time, the cushioning material attached to the contact surfaces of the protrusions and the cutouts and the contact surface of the floor substrate is compressed by the screws, so that the four circumferences of the floor material are tightly sealed. Thereby, the vibration transmission between the floor materials can be reduced by the cushioning material at the joint with the adjacent floor material. Vibration transmission between the floor material surface and the floor material installation surface is performed by a cork sheet laid in the concrete slab, a porous cushioning material between the concrete slab and the floor substrate, and a vibration isolation material provided at the tip of the floor substrate supporting means. It can be reduced. Further, the leveling of the floor surface can be easily adjusted by the adjusting means for adjusting the height of the floor substrate.

In the present embodiment, the cork sheet 6 is laid inside the concrete slab 5 because the boundary surface of the material is formed in the concrete slab and the vibration transmission is reduced by utilizing the reflection occurring at the medium changing portion of the vibration. This is because it is intended.

As described above, according to the present embodiment, by simply connecting the floor members with each other by screws, the gap that serves as a sound passage can be effectively sealed, and the floor members can be easily installed on the existing floor surface. As a result, the sound insulation performance of the floor can be improved.

[0016]

As is apparent from the above examples, the flooring material of the present invention has a multilayer structure of concrete slab, porous cushioning material, and floor substrate, and by joining the concrete slabs together, the flooring substrate and the cushioning material Independently reduces vibration transmission. Furthermore, a cork sheet is laid inside the concrete slab to form a boundary surface of the material inside the concrete slab, and the vibration transmission is reduced by utilizing the reflection that occurs at the medium changing portion of the vibration. The cushioning material on the joint surface between floor materials can effectively seal the gap that serves as a sound passage path, so by connecting multiple floor materials, the existing floor of the vibration generated on the floor surface can be connected.・ It is possible to reduce the transmission to the wall and, conversely, the transmission of the vibration of the existing floor / wall to the floor surface. By combining floor materials of several sizes, it is possible to easily use various floor surfaces. Can be configured to. Further, since the height of the floor board can be adjusted at any time by the height adjusting means of the floor board of each floor material, it is possible to easily deal with the deformation of the floor due to the uneven load.
