The present invention relates to a system for improving the overall environment of an indoor space using a double floor structure, and to a multi-family house using the same. More specifically, an empty floor space layer is formed below the double floor layer by forming another double floor layer spaced above the slab of the building. In this double floor structure, the floor space layer is used as an air passage to induce natural ventilation, thereby optimizing the environment requirements of indoor space (negative environment-inter-floor noise, heat environment-air-conditioning, air environment-ventilation, etc.) The present invention relates to a comprehensive environmental improvement system of indoor spaces used and a multi-family housing using the same.

The share of multi-family dwellings in Korea's residential buildings is increasing day by day, and the scale is also becoming larger and higher. Along with the quantitative expansion of MDUs, the quality demands for the indoor environment level of the residents living in MDUs are gradually increasing. In particular, recently, eco-friendly MDUs have emerged to pursue high quality of life. In order to realize environment-friendly MDUs, performances related to indoor environment, especially heat environment (air-conditioning), sound environment (interlayer noise), air environment (ventilation), etc., which are deeply related to the residents' health, are very important factors. It is becoming.

Almost all multi-unit houses in Korea have established a heating environment by installing on-floor floor heating structure in the process of building construction, and creating a cooling heat environment using air-conditioning equipment after completion of building construction. Ondol floor heating structure is the most commonly adopted hot water ondol structure that uses hot water as a heat source and embeds the hot water pipe in the floor structure as shown in Figure 1, such an ondol heating system provides a comfortable heat in the room by supplying heating heat It provides the environment.

However, the ondol structure currently being constructed is found to be unable to block the floor impact sound (heavy shock sound), which is a social problem. In other words, the buffer material is installed to reduce the noise between floors, but this does not reduce the weight impact sound that causes the noise between the floors. In addition, since all processes are wet, curing for foam concrete construction and finishing mortar construction is required separately, resulting in an increase in the overall construction period, which is particularly problematic in winter construction. In addition, all structures are made of a wet and integrated with the structure, there is no appropriate measures in the event of a fault, replacement work is very difficult when remodeling is required in the future, and there is a problem that the weight of the structure increases.

Proposed to improve such a conventional ondol floor structure is the ondol type double bottom structure of FIG. The double bottom structure is a method for reducing the interlaminar impact sound so that the floor space layer, which is an empty space between the slab and the upper mortar layer (double bottom layer), is formed as an interlayer buffer layer, thereby preventing the interlayer noise from being directly transmitted through the slab. The floor structure is completed by heating piping on the double floor.

However, it has been found that the conventional double bottom structure does not reduce the natural frequency of the top plate and causes resonance and resonance in the empty space and thus does not significantly reduce the floor impact sound. In addition, since the wall and the required materials are integrated in close contact with each other, the wall conducts and propagates to the wall. In other words, when the floor structure located on the upper surface has impact force, which is the cause of interlayer noise, the impact sound wave is transmitted in all directions at the solid-state transmission wavelength, and at the same time, it causes the mortar plate vibration of the double floor layer. In the bottom space layer, the lower interlayer buffer layer, resonance and resonance occur due to the negative pressure. At this time, if the edge of the structure is joined to the wall, the solid wave transmission wavelength is conducted through the wall, and if it is joined to the wall and the lower interlayer buffer layer is kept closed, the floor space layer, which is the interlayer buffer layer, is combined with the plate vibration of the double bottom layer. The generated sound pressure acts on the floor and the wall at the same time, further amplifying the force.

In order to solve this amplification problem, a method of forming a gap between the double bottom layer and the wall has been proposed as in Patent No. 490757 of FIG. 2, but it is pointed out that the construction method is complicated and a separate edge circumference plate is required. .

On the other hand, in order to improve the comfort of the occupants it is necessary to improve the indoor environment by removing the source of indoor air pollution, there is a method for increasing the indoor ventilation amount as a method for this. In general, the indoor ventilation amount is increased through the natural ventilation method depending on the opening of the windows installed in the opening or the local forced exhaust method installed in the kitchen and the toilet, there is a problem that it is difficult to secure the required ventilation amount alone. In particular, due to lifestyle habits, windows are normally closed during bedtime, so carbon dioxide emitted from the human body at bedtime does not become completely ventilated during bedtime, causing it to remain stagnant in the room.

Ventilation in the house is the air supply in the living room, bedroom and the exhaust from the kitchen and toilet, balancing the supply and exhaust is very important. In general, the air supply in the living room and bedroom is made by introducing fresh air through the window, but recently, the air supply is made so that ventilation can be performed while the window of the living room and bedroom is closed to block the effects of noise and exhaust gas. The trend is to adopt a forced air supply system with a fan. In this case, heat exchange with the exhaust gas is performed using an electrothermal or sensible heat exchanger to adjust the temperature of the introduced outdoor air to be close to the room temperature. This forced air supply method is a problem in terms of effectiveness because the price of the total heat exchanger, high efficiency and low energy consumption is essential.

Accordingly, the present inventors have devised measures to comprehensively improve the environment of the indoor space, including energy-saving, comfortable heating, noise reduction between floors, and ventilation in consideration of health, and as a result, environmentally friendly and healthy life for the occupants It has led to the development of a comprehensive environment improvement system for indoor spaces using a double-floor structure that provides space for people and apartment houses using the same.

The present invention has been made in order to improve the above-mentioned conventional problems, the floor space layer is naturally ventilated in a double-floor structure in which an empty floor space layer is formed below the double floor layer by forming another double floor layer spaced above the slab of the building. Integrated environmental improvement system of indoor space using double-floor structure that optimizes environmental requirements (sound environment-floor noise, thermal environment-cooling and heating, air environment-ventilation, etc.) The purpose is to provide apartments.

Another object of the present invention is to utilize the floor space layer secured in the construction process of the building as a space passing through the outside air introduced into the indoor air before the air is introduced into the room, without introducing a separate heat exchanger according to the season in the indoor space It is to provide a comprehensive environmental improvement system of indoor space using a double-floor structure and a multi-family house applying the same to supply at an appropriate temperature.

It is still another object of the present invention to make the floor space layer of the double-floor structure communicate with the outside and the indoor space, thereby reducing the noise between the floors and the resonance caused by the floor reflection of the impact sound wave, thereby reducing the interlayer noise. It is to provide a comprehensive environmental improvement system for spaces and multi-family housing applying the same.

Another object of the present invention is to use the floor space and the ceiling space layer secured during the construction of the building as a space for natural ventilation of the indoor space using a double-floor structure to improve the indoor air quality without opening the windows It is to provide a comprehensive environmental system and multi-family housing using this.

In order to achieve the above object, the present invention is formed on the double floor structure spaced above the slab of the building to form another double floor layer is formed below the double floor layer, the floor space layer is installed so as to communicate with the outside Air inlet; And an indoor air supply mechanism installed to communicate with the floor space layer from the floor space layer to the indoor space, wherein the air supply window is disposed in the indoor space.

In addition, the present invention provides a multi-floor floor structure having an ondol type double floor structure having a floor space layer and a double floor layer that is heat piped, and a ceiling structure having a ceiling space layer. Outside air inlet is installed so that the floor space layer of the first indoor space in communication with the outside at the same height; An indoor air supply unit installed to communicate with the inside of the first indoor space from the floor space layer of the first indoor space, wherein the air supply window is disposed on the wall while approaching the floor of the first indoor space; An indoor exhaust pipe installed to communicate with the ceiling space layer of the first indoor space from the first indoor space so that the exhaust window is disposed on the ceiling or the upper wall of the first indoor space; And an internal air exhaust outlet installed at the same height as the ceiling space layer of the first indoor space so that the ceiling space layer of the first indoor space communicates with the outside. Provides the applied apartment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

3 is a conceptual diagram illustrating a comprehensive environmental improvement system of an indoor space using a double floor structure according to the present invention. The present invention is spaced apart from a slab of a building to form another double floor layer 200 to form a double floor layer 200. In the double-bottom structure consisting of an empty floor space layer 100 below, the air space of the air supply oriented to ensure that the fresh air from the outside naturally flows evenly throughout the room without the artificial opening of the floor space layer 100 There are technical features to use. The use of such a floor space layer 100 further absorbs and distributes the impact sound transmitted from the upper double bottom layer 200 to reduce the noise between the floors and at the same time, it is possible to naturally exchange the heat energy indoors and outdoors without a separate heat exchanger. To this end, the present invention is the outer air inlet 110 is installed so that the floor space layer 100 communicates with the outside; And an indoor air supply unit 120 which is installed to communicate with the floor space layer 100 from the floor space layer 100 to the indoor space 300 so that the front air supply window 121 is disposed in the indoor space 300. That is, the outdoor air is introduced and introduced into the building sphere through the outdoor air inlet 110, and the introduced outdoor air is supplied to the indoor space 300 through the air supply window 121 of the indoor air supply via the floor space layer 100. It is.

With this configuration, the present invention can introduce fresh outside air into the room without depending on the opening of the window or the forced ventilation device.

In addition, the floor space layer 100 is in communication with the outside and the interior space 300 by the outside air inlet 110 and the indoor air supply unit 120 is not in a sealed state, the bar of the double bottom layer 200 The impact sound generated by the impact cannot be amplified and counted to the outside through the indoor air supply unit 120 and the outdoor air inlet 110, and as a result, it is expected to exert an effect on reducing the inter-layer noise.

Furthermore, while the outside air flowing into the room passes through the floor space layer 100, the slab S and the double bottom layer 200 naturally exchange heat, so that the temperature of the introduced outside air can be supplied to the room temperature without a separate heat exchanger. The bar can be completed as an energy-saving building that prevents and reduces the loss of thermal energy left in the floor space layer 100. In particular, when the building is a residential space, the heating pipe 250 is applied to the double floor 200 to complete the ondol floor, so that heat exchange occurs with the double floor 200 of the ondol floor. It can flow into the warmed state. Of course, even in the summer, the outdoor air is higher than the building structure, so that the hot outside air can be cooled and supplied by the building structure. Particularly, the night air is lower in temperature than the building structure warmed up during the day, so the night air is kept inside the building structure overnight. Once introduced, it is advantageous to cool the building during the night, so that the indoor air supply during the day can be cooled more effectively.

However, as illustrated, when the indoor space 300 has a ceiling structure having the ceiling space layer 400, the air supply window 121 of the indoor air supply apparatus is close to the floor of the indoor space 300 and the indoor space ( It is disposed on the wall of the 300, and installed to communicate with the ceiling space layer 400 from the indoor space 300, the indoor exhaust pipe 420 is disposed on the ceiling or the top of the wall of the exhaust window 421 of the front space 300 And; and the ceiling space layer 400 is a bet discharge outlet 410 is installed to communicate with the outside; if configured to include more it is possible to induce natural ventilation by the convection in the building sphere and interior. That is, since the outdoor air inlet 110 is located at the bottom and the indoor air supply unit 120 is positioned thereon, and the indoor exhaust port 420 is positioned thereon again, the outdoor air introduced through the outdoor air inlet 110 is raised by convection. While the natural air is supplied to the indoor space 300 through the indoor air supply unit 120, the indoor air is discharged to the ceiling space layer 400 through the indoor exhaust air outlet 420 while the indoor air rises by convection, and then the air outlet 410 is discharged. It is discharged to the outside through. At this time, the indoor air is not immediately discharged, but is discharged through the indoor air outlet 410 only after passing through the ceiling space layer 400 once through the indoor space exhaust pipe 420, and thus, the air is discharged. The thermal energy of is used to heat exchange with the building without being discarded as it is, has an advantageous effect in terms of energy conservation.

4A to 5C are diagrams illustrating an embodiment of a comprehensive environmental system for an indoor space using a double floor structure according to the present invention, and are divided according to a method of forming a double floor structure and whether a heat insulating material is installed. However, in all of these embodiments, a state in which the partition wall 600 for securing the air passage 150 is installed is illustrated, and an embodiment of the partition wall 600 is illustrated in FIGS. 6 and 7.

The formation of the double bottom structure may employ any conventional method, but in FIGS. 4A and 4B, a support nut 210 having a bolt nut shape (the lower portion of which is formed as an anti-vibration cushion 211) can be fixed on the bottom of the slab. Placed at intervals, and assembled by combining the pedestal 220 to bind the support in the horizontal direction all four directions to complete the one support base structure frame is shown an embodiment completed by installing the bottom panel 230 thereon. At this time, the ondol-type double floor structure is completed by heating the mortar after the piping 250 on the floor panel. As a result, a bottom space layer 100 is formed between the double bottom layer 200 and the slab S bottom surface and the double bottom layer 200 in which the bottom panel 230 is installed, and the bottom space layer 100 is outside air in the present invention. It is used as an air passage through which.

5A and 5B, the double bottom structure is generally similar to FIGS. 4A and 4B, but the insulation 500 is attached to the bottom surface of the slab S and the bottom panel 230 is installed on the support 210 without a pedestal. There is a difference in that. Since the outside air flowing into the room does not float in the floor space layer 100 so that dust or impurities on the bottom surface of the slab (S) are directly passed through the floor space layer 100, the floor surface of the slab (S) that is constructed of concrete The dust or impurities may turbid the quality of the outside air introduced into the floor space layer 100. In this embodiment, in order to prevent this, the floor space layer is installed by attaching an insulation material 500 to the bottom surface of the slab (S). 100 is formed from the heat insulating material 500 rather than the slab S. As shown in FIG. The heat insulator 500 not only serves to keep the bottom surface of the floor space layer 100 in a clean state as described above, but also to insulate the floor structure (slab, S) and at the same time to the double bottom layer 200. Shock impulse wavelengths generated in the floor space layer 200 by the impact stimulus applied to the effect of disturbing, absorbing, reducing the resonance resonance phenomenon leading to the bottom reflection from the bottom surface of the slab. The heat insulator 500 is adopted to be made in the form of a hole as shown in Figure 5c, which is to ensure that the air-proof cushion 211 of the lower portion of the support is fitted, such a hole-type insulation is added to the support 210 It can be installed on the slab (S) while fixing its position at regular intervals without the support 220.

The outdoor air inlet 110 is installed to be horizontally positioned at the same height as the floor space layer 100 to facilitate smooth inflow of the air. In this case, the outside air inlet 110 is provided with a filtering device 111 to be introduced into the room. Make sure to filter out fine dust, harmful substances and odors that may be contained in the outside air. In addition, by providing a moisture removing function and an air inflow amount adjusting function to the filtering device 111, the outside air may be introduced into the room in a more comfortable state. The outside air inlet 110 may be provided with a forced ventilation mechanism such as a power fan for forcibly introducing the outside air, the forced ventilation mechanism to be selectively operated according to the ventilation requirements.

The indoor air supply unit 120 may be installed by forming an appropriate gap at a proper position of a portion where the double bottom layer 200 and the wall meet at a right angle when the double bottom layer 200 is formed, or by embedding an air supply pipe. ), The air supply window (121, the front of the gap or the front of the air supply pipe) located in the indoor space is provided as a grille window that can be opened and closed so that the amount of indoor ventilation can be properly adjusted through the opening and closing operation as necessary. It is preferable. In addition, since the floor space layer 100 may be utilized as a wiring space for the electrical and communication cables 140, the floor wiring connection function for the information communication and home network and the abnormality check of the floor space layer at a location close to the indoor air supply 120. It is possible to facilitate the management through the air supply window 121 by installing an outlet box having a multipurpose function. At this time, the outlet box should be arranged in a state that does not interfere with the flow of air in the floor space layer (100).

The indoor exhaust port 420 and the indoor air outlet 410 are different from the indoor air supply unit 120 and the outdoor air inlet 110 installed to communicate with the floor space layer 100 in that they are installed to communicate with the ceiling space layer 400. The overall configuration is the same. The exhaust window 421 of the front surface located in the indoor space 300 in the indoor exhaust port 420 may be formed in the form of a grill window on the ceiling or wall or by forming a gap in the curtain box.

As shown in FIGS. 4A and 5A, when the partition wall 600 is installed in the bottom space layer 100, an air flow path 150 may be formed. That is, by installing the partition wall 600 in the floor space layer 100 so that the outside air inlet 110 and the indoor air supply unit 120 are located in the same space, the floor space layer 100 is separated and separated, and as a result, the outside air inlet ( Only the space where the 110 and the indoor air supply unit 120 is located is to function as the air flow path 150 through which air flows. Securing the air flow path 150 plays an advantageous role in supplying the indoor air quickly to help the smooth flow without remaining in the floor space layer 100 is introduced. The partition wall 600 is preferably arranged in a zigzag as in FIGS. 4a and 5a so that the air flow path 150 is secured over a long distance while bypassing the floor space layer 100. This is to improve the heat exchange efficiency of the outdoor air introduced into the building to stay in the floor space layer 100 for a long time is covered in winter and cooling in the summer. As a result, it is possible to introduce heat energy that can not be left under the double bottom layer 200 into the room, and thus it is possible to construct a double bottom structure with improved thermal energy efficiency.

The partition wall 600 is made of a sound absorbing material to block, absorb, and reduce the impact sound caused by the impact stimulus on the upper portion of the double bottom layer 200 to resonate to the surroundings by causing resonance resonance in the lower bottom space layer 100. Adopt one. The partition wall 600 may be manufactured in various forms, and examples thereof include a block form (FIG. 6) and a panel form (FIG. 7). The block-shaped partition wall 610 as shown in FIG. 6 can be completed simply because it is not a problem to be installed independently by securing a sufficient bonding area as the member itself, but the panel block 620 as shown in FIG. In order to secure the area, it is preferable to have a horizontal seating portion having a predetermined width horizontally on the top of the vertical panel. In particular, the panel block 620 can be easily cut in some cases by forming a plurality of wrinkles 627 in the lower portion of the vertical panel, and the height of the vertical panel is adjusted by its own load, thereby improving its usability. . However, as shown in FIGS. 4A and 4B, in the double bottom structure formed of the support 210 and the pedestal 220, the partition 600 is combined with the pedestal 220 constituting the bottom of the double bottom layer 200. If the structure is formed, the installation can be easily guided, and 6 and 7 shows the partition wall is formed with coupling grooves (615, 625) so that the pedestal 220 is accommodated and coupled regardless of its shape. Of course, when the bottom panel 230 is supported by only the support 210 without a pedestal as shown in Figures 5a and 5b adopts a general partition bulkhead 600 is not formed.

The block-shaped partition wall 610 of FIG. 6 is a partition wall structure in which a coupling groove for accommodating the pedestal in the block is formed at a pedestal installation interval.

The partition wall 620 of FIG. 7 has a structure in which the partition wall 620 of the panel form is coupled to each other and is coupled to each other during installation. The partition wall is easily applied in the field. It is expected to be. Specifically, the partition wall 620 of the panel form of FIG. 7 is not coupled to the pedestal 220, the first panel 621 abuts on the bottom panel 230 is installed on the pedestal; and directly in contact with the pedestal 220 The second panel 622 to be combined; is produced by separating. The first panel 621 is completed by configuring a horizontal seating portion 621b having a predetermined width horizontally on a single vertical panel 621a. The second panel 622 has two vertical panels 622a having a height smaller than that of the vertical panel 621a of the first panel by the thickness of the horizontal seating part 621b, and the thickness of the vertical panel 621a of the first panel. While spaced apart by as much as possible, it is completed by forming the coupling groove 625 has a coupling groove seating portion 625b having a predetermined width while forming a defect groove 625 on the two vertical panels (622a). In this case, the coupling groove seating portion 625b may be formed of a bottom surface and both sides, and in this case, both sides of the coupling groove seating portion 625b may have two vertical panels 622a of the second panel by the thickness of the horizontal seating portion 621b of the first panel. Made to protrude. The first panel 621 and the second panel 622 of such a configuration are coupled to each other by sandwiching the vertical panel 621a of the first panel between the two vertical panels 622a of the second panel, the first panel Since the horizontal seating portion 621b is also located above the two vertical panels 622a of the second panel, the horizontal seating portion may be formed as a panel-shaped partition wall 620 that is tightly installed as a whole.

Although not shown, the partition wall 600 may be installed in the ceiling space layer 400 in the same manner to form an air passage for exhausting indoor air.

8 is a view illustrating a multi-family house to which a comprehensive environmental system of an indoor space is applied according to the present invention, and shows that an outdoor air inlet 110 and an air outlet 410 are installed in a living room so that natural ventilation is performed around them. .

Install the outside air inlet 110 so that the floor space layer 100 communicates with the outside at the same height as the floor space layer 100 of the living room in contact with the outside, and bet the ceiling space layer 400 of the living room to communicate with the outside. Install the outlet 410. The bedroom and the kitchen, which are other indoor spaces, are made so that the floor space layer 100 and the ceiling space layer 400 are continuously connected to each other in the living room, and this can be completed by installing the connection vents 160 and 460. Since the living room balcony is usually incorporated in the same space area as the interior, the actual outdoor air inlet 110 is installed to extend from the balustrade of the balcony to the lower part of the door frame of the living room door, and the bet outlet 410 is also the same. On the other hand, when the balcony is directly exposed to the outside air, the air inlet can be installed directly under the living room partition.

The apartment house configured as described above eventually receives fresh air from the living room and passes through the floor space layer 100, while some are supplied to the interior of the living room through the indoor air supply unit 120, and some of the connection pipes 160 of the floor space layer are provided. After passing through the floor space layer 100 of the bedroom and the kitchen, the introduced air is supplied into the interior through the indoor air supply unit 120 of each of the bedroom and the kitchen. The air supply to each of the interior of the space is ventilated to the interior space and then discharged to each ceiling space layer 400 through the indoor exhaust vent 420, the discharge air of the living room is discharged to the outside through the direct bet outlet 410 and the bedroom And the discharged air of the kitchen passes through the ceiling vent layer 460 of the ceiling space layer and passes through the ceiling space layer 400 of the living room is discharged to the outside through the final bet outlet 410. As a result, since supply and discharge are made by convection, it is possible to induce natural ventilation without opening windows. In addition, the multi-unit housing configured as described above can be expected to reduce the impact sound as well as the heat exchange effect as described above.

According to the present invention as described above, by forming another double floor layer on the slab of the building by using the floor space layer as an air passage to induce natural ventilation in the double floor structure consisting of an empty floor space layer below the double floor layer It will create the effect of optimizing the environmental requirements of indoor space (negative environment-floor noise, thermal environment-cooling and heating, air environment-ventilation, etc.).

Specifically, the floor space layer secured during the construction process of the building is used as a space through which fresh air flows into the room before being introduced into the room, and the outdoor air can be supplied to the indoor space according to the season without a separate heat exchanger. As the floor space layer of the double-floor structure communicates with the exterior and interior spaces, the impact sound wave is counted up, and the noise between floors can be reduced by the disturbance of resonance resonance caused by the floor reflection. By utilizing the floor space and the ceiling space layer secured in the process as a space for natural ventilation, the indoor air quality can be improved by inducing natural ventilation without opening windows.
