Construction Structure of Floorboard with Sound Absorption Structure

The present invention relates to the construction of a floorboard having a sound absorbing structure, and more particularly, a plurality of curved plates filled with a foamed resin having a predetermined thickness on one side in a synthetic resin storage plate body having an assembly structure at the bottom to facilitate construction. It is laminated so that the curved surface is intersecting, between the sound absorbing material such as glass wool (glass wool) having a certain thickness between the upper and lower portions of the sound absorbing material by forming a plurality of hollows, the sound absorption effect is excellent In addition, the present invention relates to a construction of a floorboard having a sound absorbing structure that can be obtained together with the rigidity and ease of construction work by cross-lamination of a curved plate.

In general, noise causes discomfort, discomfort, and excite the listener if repeated.

The discomfort of this noise is determined by the intensity and frequency of the sound. For example, the high sound is louder than the low sound, and the simple sound is louder than the sum of the various frequency components.

Sounds that touch the walls or slabs that separate the top and bottom layers are partially reflected, partially absorbed, and others transmitted.

Noise is attenuated in various forms depending on the shield, and it is known that a sound absorbing material that is absorbed in contact with a porous material and absorbs about 70% or more of sound energy on the market.

The sound absorbing material is filled in the usual way to the slab surface in which the upper and lower floors are divided and divided in the construction of multi-storey buildings such as apartments, townhouses, and office buildings.

Filling the sound absorbing material in the above is widely used for the purpose of buffering or canceling the noise generated from the upper layer.

In the construction of the floorboard, conventionally, the sound absorbing material is simply arranged and arranged on the slab surface, and a finishing material such as the floorboard is installed on the upper part, so that a slight vibration or shock is applied to the floorboard, but it is attenuated by the sound absorbing material. Most of the sound, that is, the noise, is transmitted directly to the slab surface, so that the entire building vibrates.

In particular, such a noise problem has resulted in the transfer of noise to the lower floors in residential environments such as apartments or townhouses. Therefore, there is an urgent need for the construction of noise regulation measures and complete removal of noise due to noise pollution.

In order to solve this problem, various types of sound absorbing members have recently been proposed by each manufacturer. However, these conventional technologies are very complicated to make the sound absorbing structure, so it is very difficult to manufacture them, and accordingly, production cost and supply cost Is very high, and more importantly, the sound absorbing effect is reduced, so that the noise canceling function is not fully performed.

Thus, the present inventors place and fix the curved plate filled with foamed resin on one side to the upper part of the storage plate made of synthetic resin material in order to solve the above-mentioned problem in the building structure already filed with the Korean patent application No. 96-14657. After filling the mortar on the top and providing the floorboard or roofboard having a sound-absorbing structure achieved by the construction of the hardener has provided the advantage of damping and absorbing the noise of the upper and lower floors to some extent.

However, the patent application of the inventors of the present invention adopts a flexible plate coated with a foamed resin, but there is a sound absorbing function due to the porous plate and the foamed resin, but the hollow part that can block and attenuate the sound is not formed, hardner, mortar, Since the curved plate and the storage plate are integrated into the frame, the hollow part is formed in the inner surface by the frame, so the plate is suitable for being used in the frame of the prior invention, which is prefabricated. In the case of adopting the method of directly installing the slab on the slab, structural defects are difficult to expect a perfect sound absorption effect.

The present invention has been devised to solve the problems and problems that the prior art of the present invention has not solved the above problems and to improve them, the purpose of providing this is a certain thickness in one side in the synthetic resin storage plate Sound absorbing structure provided with a plurality of curved plates filled with a foamable resin of the plurality of curved plates to be laminated so that the curved surface intersects therebetween, with a plurality of hollows formed on the upper and lower portions of the sound absorbing material through a sound absorbing material such as glass fiber having a predetermined thickness therebetween. It is to provide a floorboard with.

Another object of the present invention is to provide a floorboard having the sound-absorbing structure as described above to be excellent sound-absorbing effect, and to obtain a firmness and ease of construction work by the cross-lamination of the bending plate.

In order to achieve the above object, it will be more clearly described in detail with reference to the accompanying drawings.

That is, the present invention is as shown in the accompanying drawings, Figures 1 to 4,

In the upper part of the frame (1) spaced at regular intervals, the locking jaw 21 is formed on both lower sides, and the synthetic resin storage plate body 2 having a predetermined area having an accommodating space 22 therein is re-fixed,

The accommodating space 22 of the storage plate body 2 is laminated in a form in which a plurality of curved plate bodies 3 and 4 coated with foamed resins 31 and 41 on one side thereof face each other and cross each other. By the plurality of hollow portions 5 are formed therebetween,

Between the curved plates 3 and 4, a sound absorbing material 6 such as glass fiber having a predetermined thickness is sandwiched to form a sound absorbing and air layer 7,

A plurality of floorboards 8 configured to be assembled and attached are formed on the upper surface of the foamed resin 41 on the upper side of the curved plate 4 located above.

At this time, the floorboard body 8 is made of the same standard as the needle plate 81 and the upper plate 82 is fixedly attached to the diagonal direction of one side to be mutually assembled.

As an unexplained symbol, 9 represents a slab of a building.

Referring to the operation of the present invention made of such a structure as follows.

First, the present invention arranges and fixes a plurality of frameworks 1 having a predetermined length on the upper surface of the slab 9 of the building at equal intervals, and a conventional fixing means, that is, an application such as an adhesive on the upper surface of the framework 1 After application, when the catching jaws 21 of the storage plate body 2 made of synthetic resin are matched and placed, the storage plate body 2 is fixed to the upper surface of the frame 1 by its own weight.

In this state, the lower flexure plate 3 having the foamed resin 31 filled on one surface is re-fixed first to the accommodating space 22 formed in the storage plate body 2, and the flexure plate 3 In the upper part of the), a sound absorbing material 6 such as glass fiber having a predetermined thickness and area is disposed on the front surface.

In this state, the upper curved plate 4 is placed on the upper side of the sound absorbing material 6 while the lower curved plate 3 is placed and fixed in such a manner that the curved surfaces cross each other, and the curved plate 3 is fixed. And (4) are cross-mounted and the sound absorbing material 6 interposed therebetween to form a plurality of hollow portions 5 at the upper and lower portions of the sound absorbing material 6 and to form a sound absorbing air layer 7 at the same time. do.

When the above work process is made, a plurality of floorboard bodies 8 which are assembleable are arranged on the upper surface of the expandable resin 41 of the curved plate 4 located on the upper side, and then fixed by fixing means such as adhesive. Construction work is very simple and easy.

After the construction of the floorboard body having such a sound absorption structure of the present invention is made, it may be used or used according to a conventional method,

At this time, when an impact is applied to the floorboard body 8 due to an undesired occurrence factor or noise is generated in the room, there is a noise attenuation effect that is normally attenuated by the foamed resin 41 of the upper curved board body 4. The transmitted noise reaches the sound absorbing air layer 7 formed by the hollow portion 5 and the sound absorbing material 6 formed between the upper and lower curved plate bodies 3 and 4, and is completely eliminated.

The noise removing effect from the sound-absorbing air layer (7) is in the form of being held by the hollow portion (5) while the impact of the noise is repeated by hitting the wave formed on the upper and lower bent plate (3), (4) The attenuated noise is greatly attenuated, and the attenuated noise through the above process is completely removed by the absorbing action by the structural characteristics of the sound absorbing material 6 made of porous or fibrous tissue such as glass fiber.

Noise reduction effect by the sound-absorbing air layer (7) as described above to properly solve the noise pollution that can be generated between the upper and lower floors of the multi-storey building, such as apartment or townhouses to create a comfortable residential and office environment.

According to the present invention, there is provided a plurality of curved plates filled with a foamable resin having a predetermined thickness on one side in the synthetic resin storage plate, and laminated so that the curved surfaces intersect, and a sound absorbing material such as glass fiber having a predetermined thickness therebetween. By forming the sound-absorbing air layer therebetween, it is obvious that the sound-absorbing effect is greatly improved, and it is a very advantageous design that can be obtained together with the rigidity due to the cross-lamination of the curved plate and the ease of construction work.
