Description

{A floor structure having a alarm of a noise transmission}

The present invention relates to an interfloor floor structure of a building equipped with a warning function, and more particularly, to measure an interlayer noise on a building and to alarm when excessive noise is measured, and to absorb a shock and vibration generated from an upper floor. It relates to an interlayer floor structure of a building with a warning function that effectively prevents noise and vibration from being transmitted to the lower floor.

In general, a common construction method of two-story or more buildings such as apartments or multi-unit houses is to construct concrete slabs according to the number of floors of the building to complete the basic construction, and then arrange heating pipes on the concrete slabs at regular intervals. In the construction of gravel and cement mortar to a predetermined thickness.

As the slab that divides the floors and floors of multi-storey multi-storey buildings such as apartments and high-rise buildings is constructed of concrete only, the noise and shock generated inside the relevant floor of the building are directly lowered through the interlayer slabs. Is passed to.

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

For example, an impact such as a drop of an object is applied to the floor or a movement of a chair generates a solid transmission sound, and the solid transmission sound is transmitted to the lower floor through the floor slab.

Nowadays, the problem of floor noise has emerged seriously in apartment houses, and the government has announced that it will impose penalties for neighboring noise-induced acts by applying the neighboring crimes of the misdemeanor punishment law, and even struggling between neighbors with floor noise. As a result, 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 for reducing and minimizing the serious noise between floors have been proposed. In the conventional conventional interlayer floor structures, a lightweight foam concrete layer is formed on the basis of the concrete slab, At the top, a heating plumbing and finishing mortar layer is formed, on top of which is composed of a flooring layer of decorative material such as monolium, solid wood, and tiles.

However, the interlayer floor structure above, but the lightweight foam concrete layer formed on the concrete slab is responsible for attenuating the noise, but the situation that does not properly absorb or block the noise, such as light impact sound and heavy impact sound. Therefore, when a building is constructed with such a conventional floor structure, the noise and vibration caused by the impact applied to the floor by, for example, the children's running on the upper floor, are immediately transmitted to the lower floor, and as a result, the comfort of the building is greatly reduced. Will be.

Due to this, in order to more effectively block noise or impact, a construction method for forming an interlayer noise preventing material between the concrete slab and lightweight foamed concrete has been developed.

Such an interlayer noise prevention material is usually made of a resin material, and provides a floating structure for forming an air layer by forming protrusions on the bottom surface, wherein the hardness of the interlayer noise prevention material and the protrusions is 40 or less or 80 or more.

However, since the hardness of the interlayer noise preventing material and the protrusion is about 20 to 40, it is very flexible and excellent in elasticity. In fact, the existing layer of noise preventing material is laid on the slab surface of the apartment house, and light weight foam concrete and finishing mortar are placed on it. When pressed under the weight of lightweight concrete and mortar (170kg per 1m × 1m), interlayer noise prevention material and projections are attached to the slab surface, and no air layer is formed, and the function to block vibration and noise is lost. The reality is that it is very slight.

In addition, the air layer may be formed when the hardness of the interlayer noise preventing material and the protrusion is 80 or more, but the noise is secured by the air layer because the protrusion is attached to the slab surface and the noise is transmitted through the strong interlayer noise preventing material and the protrusion. It will cancel the blocking effect.

In addition, there are many kinds of floor noise prevention materials that are currently used, but there are many types, but all of them are laid on the concrete slab surface of the apartment house, so the noise blocking effect is not great. For example, the existing interlayer noise prevention material is mainly in the form of laying styrofoam insulation or other synthetic resin foam sheet on the slab surface of the multi-family house and placing lightweight foam concrete and mortar on it, there is a disadvantage that the noise is not blocked and transmitted.

In general, when the noise between floors does not know how much noise is transmitted to the downstairs often do not recognize the pain felt in the lower floors are often not careful.

The present invention has been made to solve the problems as described above, to provide a structure that can be warned and careful not only to the cause of the cause cause if the interlayer noise occurs, but also if the occurrence of more than the set value. There is a purpose.

The shock and vibration generated are absorbed by the elastic plate, and when the guide protrusion is inserted into the guide groove and pressed with a strong force from above, the force exceeding the force absorbed by the elastic force of the elastic plate is deep in the guide groove. It is intended to be configured so that the shock is absorbed while the air in the space is compressed while being pressed.

The elastic pad is intended to increase the adhesion of the contact space between the shock absorbing plate and the slab.

By installing a listening box that can measure the inter-layer noise on the slab in advance, it is easy to measure the inter-layer noise on the floor.
