Description

Ondol floor board

The present invention relates to an ondol floorboard, and more particularly, to improve the workability of the ondol floorboard by integrally attaching an interlayer noise blocking panel to block interlayer noise on the bottom of the ondol floorboard stacked on the cement (concrete) floor of a multi-family house. At the same time, to minimize the noise transmission through the wall or floor, and to prevent the deformation of the panel by heating and to improve the durability of the interlayer noise floor panel is attached to the ondol floorboard.

In general, a multi-storey building is equipped with a slab or a barrier (H BOARD, EVA) to block the noise between floors to prevent the impact or noise generated between floors from being transferred to the lower floor. I am building a slab.

The interlayer noise structure and the barrier material as described above are constructed with a floating floor structure to reduce noise against heavy impact sound and light impact sound, and the barrier material is constructed by inserting a barrier sheet or a panel into the slab.

Moreover, in the case of multi-storey multi-unit houses such as apartments or multi-family houses, the impact sound is blocked through a block sheet or a barrier panel when installing slabs that divide the floors in order to protect residents from the noise of the floors.

A typical example of the inter-layer noise blocking structure of such a multi-family building is shown in FIG. 1.

In Figure 1, the member number 1 is a slab, 2 is a barrier layer, 3 is a lightweight foam concrete, 4 is a pipe layer, 5 indicates a finish layer.

As shown therein, the floor structure of a conventional multi-family building is a slab (1) made of reinforced concrete and the barrier layer (2) laminated on the upper side of the slab (1) and the upper side of the barrier layer (2) Is constructed by laminating a lightweight foamed concrete layer (3), a pipe layer (4) and a finish layer (5).

The barrier layer 2 as described above is constructed with a roll-shaped noise barrier sheet or noise barrier panel made of a rubber system and a glass surface, and the light-weight foamed concrete layer 3 under the piping layer 4 for heating is insulated. It is being constructed for.

In addition, the finishing material layer (5) is being constructed with a variety of finishing materials, but in recent years is a lot of construction is on the floor or reinforced floor, which is easy to install and easy to replace when damaged.

However, the above-mentioned floorboards laminated on the floor of the conventional multi-unit house, except for laying the barrier layer with a roll-type noise barrier sheet or noise barrier panel on the upper side of the slab, reduce the inter-layer noise, or interlayer noise prevention layer to block the piping layer. Because it is not formed, it is not possible to suppress moisture and interlayer absorption, and it is difficult to construct by laminating lightweight foamed concrete and piping layer, and construction cost is incurred, and it is difficult to repair when the barrier layer is damaged. There was a problem.

Therefore, it was difficult to repair when noise occurred due to the decrease of interlayer noise blocking rate due to long time use.

In addition, even if the floor part of the apartment house is constructed by blocking the noise blocking layer, separate construction is required in the space where more noise should be blocked according to the functions such as the children's room where the noise is loud or the room where music or musical instruments are played. There was a problem that the noise was transmitted to the wall or floor through the pipe layer or the lightweight foam concrete layer without directly blocking the noise due to the weight and light impact generated through the top of the ondol floor or reinforced floor plate.

In view of the above problems, there is provided a building floor sheet of Utility Model Registration No. 0336887.

This maximizes the shock absorption rate and thermal conductivity to facilitate the shock absorption by using the foam sheet, but can not prevent the foam sheet formed of polyethylene or polypropylene from being deformed by heat to prevent deformation of the foam sheet. There was a problem that could not be.

In addition, a floor noise reduction material for a building of Utility Model Registration No. 0387009 has been proposed.

It forms the noise reduction material between the upper panel, the lower panel and the middle panel and forms a plurality of holes in the middle panel to fill sand and sawdust or to crush the expanded polystyrene, but this is not the solidified material. Since the filling in the holes of the upper panel and the lower panel to form a filling material in each hole, the productivity was reduced.

As described above, the noise reduction material of the interlayer noise reduction material has an effect of reducing noise by materials having different specific gravity, but the filler is not solidified, and thus, the deformation of the panel due to heat cannot be prevented. There was a problem leaking into.

On the other hand, the Utility Model Application No. 2007-13852 interlayer noise blocking panel proposed by the present applicant solves the problems of the above panel, but the productivity decreases because the support having a small coefficient of thermal expansion must be inserted into the insertion hole, respectively. There were frequent departures from multiple supports.

Therefore, the present invention was devised in view of the above-mentioned problems of the prior art, and its purpose is to attach the interlayer noise blocking panel to the bottom of the ondol floorboard to reduce the interlayer noise, to improve the deformation prevention and durability, and to improve the workability and repair. It is to provide an easy ondol floorboard.

Another object of the present invention is to provide an ondol-floor plate attached to an interlayer noise prevention panel that can increase productivity by reducing the number of work by forming the support in the longitudinal direction so that it is not necessary to insert the support for each part.

In order to achieve the above object in the construction of the ondol ridge plate on the ridge floor plate laminated to the upper side of the pipe layer formed on the floor of the apartment building,
Attaching the interlayer noise blocking panel to block the interlayer noise in the longitudinal direction on the bottom surface of the ondol floorboard, the interlayer noise blocking panel is spaced apart every 10 cm spacing disposed urethane foam panel layer of 50 cm wide, Between each spaced apart the panel layer is characterized in that it is configured by attaching a deformation preventing panel made of any one selected from a stone or wood of 10 mm thickness thinner than the thickness of the panel layer.

As described above, the present invention is easy to install and repair by attaching the interlayer noise blocking panel to the ondol flooring board without installing the ondol flooring plate and noise blocking panel separately when constructing the floor of the apartment house. It improves the deformation prevention and durability of the ondol floorboards, and it is possible to easily block the noise between floors only by constructing the ondol floorboard to which the interlayer noise blocking panel is integrally attached.

In the above, the present invention has been shown and described with reference to certain preferred embodiments, but the present invention is not limited to the above-described embodiments, and the present invention is not limited to the spirit of the present invention. Various changes and modifications may be made by the user.

2 is a perspective view illustrating the interlayer noise blocking panel attached to the ondol ridge plate of the present invention, and FIG. 3 is an enlarged cross-sectional view of the interlayer noise blocking panel attached to the ondol ridge plate of the present invention.

As shown in Fig. 2 and 3, the interlayer noise blocking panel of the present invention is integrally formed with the ondol floorboard 5 laminated to the upper side of the pipe layer 4 formed on the floor of the apartment building.

The interlayer noise blocking panel as described above forms a panel layer 10 formed of an expandable synthetic resin having elasticity, and the panel layer 10 is preferably formed of urethane foam.

The panel layer 10 is formed through the deformation preventing panel 20 in the longitudinal direction at regular intervals.

Preferably, the deformation preventing panel 20 is formed of stone or wood having a low coefficient of thermal expansion, and both sides of the anti-deformation panel 20 are bonded to the panel layer 10, but are formed thinner than the thickness of the panel layer 10. Effective for reducing noise between floors.

The deformation preventing panel 20 is preferably formed 10 cm wide for every 50 cm interval of the panel layer 10.

Referring to the operation and effects of the present invention configured as described above are as follows.

First, as shown in Figure 4 by constructing a lightweight foamed concrete (3) of 50 ~ 60mm thickness to the upper side of the slab (1) of the floor of the apartment building constructed of a slab (1) of about 150 ~ 180mm thick Construct to satisfy the insulation performance prescribed by the Building Code.

Above the lightweight foamed concrete 3, the piping layer 4 in which the mortar layer and the ondol piping were installed is constructed.

Ondol with an interlayer noise blocking panel formed of the panel layer 10 and the strain preventing panel 20 adhered to the bottom surface of the ondol flooring plate 5 before the ondol flooring plate 5 is installed above the piping layer 4. Construct the floorboard (5).

Since the interlayer noise blocking panel is bonded to the bottom surface of the ondol floorboard 5, it is possible to reduce the process of laminating the interlayer noise blocking panel and simultaneously install the ondol floorboard that can block the interlayer noise at the same time. Convenience can be increased.

In addition, the ondol floorboard 5 to which the interlayer noise blocking panel is integrally formed is made of foamed urethane or raw rubber which absorbs the impact of the panel layer 10, thereby alleviating interlayer noise due to impact and the like. By forming a deformation preventing panel 20 at predetermined intervals of the panel layer 10, the deformation of the panel layer 10 may be prevented while supporting the load applied to the ondol floorboard 5.

The panel layer 10 can be produced by adding a variety of ocher powder, ceramic powder, aroma fragrance and the like to not only block noise but also make indoor air comfortable.

The construction of the interlayer noise blocking panel as described above is made by manufacturing the panel to meet the standard of ondol floorboards. The interlayer noise isolation panel is attached to the ondol floorboard.

In addition, forming the deformation prevention panel 20 10 cm wide every 50 cm interval of the panel layer 10 is to repeatedly form the panel layer 10 (sample 1) and the deformation prevention panel 20 in the same width ( Lightweight impact sound blocking performance is superior to sample 2) as shown in the following graph 1.

Graph 1

As shown in Graph 1, the results of comparing the light-shock shock-shielding performance of Sample 1 and Sample 2 by frequency band showed a difference of up to 12.6dB.

As a result of comparing the noise blocking panel with four types of floor finishing materials such as plywood floor, reinforced floor and wood floor, and wood floor pad type, and the frequency bands, in the case of Sample 1, PE foam was applied to the bottom of the finishing material. Blocking performance similar to the reinforced floor and solid wood flooring was found to be secured. In the case of Sample 2, the blocking performance was better than that of plywood flooring and solid flooring without flooring material, but the blocking performance was lower than that of flooring material with flooring material. appear.

Graph 2

In general, the impact sound insulation performance of floor finishing materials is evaluated by the weighted floor impact sound level attenuation specified in KS F 2863-1.

The Ministry of Construction and Transportation Notice No. 2006-435, which specifies the physical performance of shock absorbers and insulating materials used in standard floor structures, specifies that the weight of the floor finishing sound level attenuation of the floor finishing material is 13 dB or more.

As shown in the measured graph 2, Sample 1 and Sample 2 were found to satisfy all 13dB, the attenuation of the floor finish material prescribed in the relevant notice, and in the case of Sample 1, the blocking performance was higher than that of the reinforced floor and the wooden floor where the base material was installed. The excellent 19dB resulted in better light impact sound blocking performance than comparable finishes.
