Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a floor slab,

The present invention relates to an ondol slab structure for apartment houses, and more particularly, to a detachable ondol slab for preventing the interlayer noise from being reduced by improving the ondol slab constituting the bottom layer of the apartment house.

Recently, apartment houses such as apartments have become commonplace, and stranger disputes are becoming a serious social problem due to the interlayer noise.

Generally, in the case of apartments or multi-storey buildings such as apartments, the sound of air is blocked by the concrete slab structure. However, when impact or vibration is directly applied to the floor due to walking or dropping of objects from the upper floor, And is transmitted to the lower or adjacent generation through the floor slab, the ceiling, and the wall.

Such a floor impact sound is a heavy impact sound that generates a lot of low frequency components such as a light impact sound that generates a lot of high frequency components such as a falling sound of a bowl or a moving object and a chair, .

In order to reduce the interlayer noise of such a dwelling unit, as shown in Fig. 1, the floor slab 2 of the multi-layer structure is formed thick or the heat insulating material or the damping material 3 is provided on the upper part of the floor slab, A method has been proposed in which a hot water pipe 4 is provided on an upper portion of a heat insulating material or a cushioning material to form the ondol layer 5. [

However, when the thickness of the bottom slab is increased, the effect of reducing the weight impact sound is greater as the thickness of the floor slab is thicker. However, the weight of the concrete is increased as well as the weight of the concrete is increased There is a problem that the cost of construction increases as a whole.

Further, when the heat insulating material is provided on the floor slab, it is effective to reduce the light weight impact sound. However, as the weight of the ondol layer provided on the heat insulating material increases, the natural frequency of the floor slab decreases. There is a problem that the measured value of the heavy impact sound increases rather than the case where the ondol layer is formed due to the influence of the reverberation of the bass sound.

As a conventional technique, Korean Patent No. 1248032 discloses a method for reducing interlayer noise, in which a polyethylene foam is laid on the top surface of a floor slab, a sound absorbing material having a plurality of dust holes formed at predetermined intervals is piled on the polyethylene foam, A heat insulating material is laid on the cushioning material, a piping panel is stacked on the heat insulating material, and heat conduction is performed on the heat insulating material, A floor heating panel, a floor panel, a floor panel, a floor panel, a floor panel, a floor panel, and a ceiling board.

However, in order to reduce the interlayer noise by the above-described conventional techniques, it is necessary to provide a polyethylene foam, a sound absorbing material, a vibration absorbing material, a magnesium board, a cushioning material, a heat insulating material, a heat conduction plate and a piping panel on the top of the bottom slab There is a problem that the number of members to be installed is greatly increased, and the construction cost and the material cost are greatly increased.

Even if an impact load is applied to the floor slab, it is possible to prevent a vibration from being generated in the entire ondol layer as in the prior art, thereby reducing a heavy impact sound and increasing the impact reduction effect of the floor slab.

That is, as in the prior art for preventing interlayer noise, a polyethylene foam is laid, a sound absorbing material is piled on a polyethylene foam, a vibration proof hole is inserted, a magnesium board is laid on a sound absorbing material, a cushioning material is laid on a magnesium board, It is not necessary to construct many components such as a heat insulating material or to install a sound absorbing panel having a complicated structure for a dry installation in a prefabricated manner and to divide the ondol layer into small pieces and divide the damping portion It is possible to effectively reduce the heavy impact sound while the structure is simple and the construction is easy.

Further, the damping effect is generated by the damping part absorbing the friction with the adjacent ondol unit by the damping part, and the impact load acts on only a part of the damping material layer provided below the ondol layer, thereby increasing the role of the damping material .

Meanwhile, the separation type Ondol slab for preventing interlayer noise according to the present invention may further include a pipe support frame 30 provided between the ondol layer and the buffer material layer.

The piping support frame 30 is manufactured to have substantially the same size as the ondol unit 10, thereby facilitating installation of the piping support frame and installation of the ondol unit.
