Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a balcony insulated structure and a construction method thereof,

[0001] The present invention relates to a balcony insulation structure for blocking heat bridges and a construction method thereof, and more particularly, to a balcony insulation structure for blocking heat transmission between upper and lower generations in a balcony portion of a multi- .

Passive houses are energy-saving houses that minimize energy use by restricting the heat flow of the house. To this end, the heat insulation effect is maximized by making full use of the insulation and thickening the wall, and by using a triple window of the window. In recent years, more and more passive houses are emerging as zero energy houses. Zero Energy House refers to an energy-independent house where the annual energy use of the house and the resulting carbon emission effect is zero. A zero energy house consists of a passive element and an active element. The passive element is intended to preserve the internal energy of the building. It consists of high insulation, high airtightness, high performance window, exterior shade, double skin, and the active element converts fossil fuel or renewable energy into energy And renewable energy.

The government has introduced the zero energy building certification system from this year in order to intensively promote the zero energy house as one of the energy new industry, and is stepping up the mandate gradually in the public sector in 2020 and the private sector in 2025.

Passive houses and zero energy houses commonly use high thermal insulation structures to conserve energy inside buildings.

The heat insulating structure is a structure for preventing the heat from being radiated to the outside or coming in from the outside. Such a heat insulating structure can be classified into an outer heat insulating structure, a middle heat insulating structure and an inner heat insulating structure depending on the place where the heat insulating material is installed.

The outer heat insulating structure has a structure in which a heat insulating material is provided outside the outdoor wall. However, since the heat insulating material is installed outside the building, it is difficult to construct the heat insulating material. The heat insulating structure is a structure in which a heat insulating material is installed on the inner side of the inner wall, which is advantageous in terms of construction. However, there is a drawback that localized condensation may occur due to heat bridging.

In a multi-family house or the like, a balcony is installed, and the veranda is installed on the front and rear sides of each unit household. For example, the apartment has a balcony on the front and rear. In the case of apartment houses, the heat insulation structure is used rather than the outer insulation structure. In the case of forming the thermal insulation structure, the insulation material is installed only on the wall forming the balcony, and the slab forming the balcony is not provided with the insulation material. Therefore, heat loss occurred through the slab that forms the balcony, which acted as a stumbling block in the fabrication of a passive house or a zero energy house.

FIG. 1 is a longitudinal sectional view of a balcony insulation structure for blocking heat bridges according to an embodiment of the present invention, and FIG. 2 is a horizontal sectional view of a balcony insulation structure for blocking heat bridges according to an embodiment of the present invention.

1 and 2, a balcony insulating structure according to an embodiment of the present invention includes a slab slab insulator 200 inserted into a balcony slab S forming a floor of a balcony, And bottom and ceiling insulation materials 210 and 220, respectively, which are in contact with the lower surface. At this time, the slab insulation 200 and the ceiling insulation 220 are in close contact with each other.

First, the balcony slab S having the slab insulation S will be described.

The balcony slab S includes a plurality of main reinforcing bars 110 arranged in one direction and a plurality of reinforcing bars 110 arranged in a direction intersecting the plurality of main reinforcing bars 110 to widely distribute the stress generated in the main reinforcing bars 110. [ A plurality of slab slab insulators 200 inserted into a plurality of grids G formed by intersecting a plurality of main reinforcing bars 110 and a plurality of reinforcing bars 120, And a concrete 300 placed so as to enclose the plurality of main reinforcing bars 110, the reinforcing steel bars 120, and the slab insulator 200.

The balcony slab S forms a floor or a ceiling of a balcony and is generally provided between the outdoor space and the indoor space to serve as a buffer zone to buffer sudden temperature changes in the outdoor space and the indoor space. Also, in recent years, it has been used extensively as an indoor space.

A plurality of main reinforcing bars 110 and reinforcing bars 120 are laid to form a balcony slab S, The thermal conductivity of the reinforcing bar 110 is very high and the slab slab insulator 200 is installed inside the balcony slab S to prevent heat transfer through the balcony slab S, However, as described above, since the main reinforcing bar 110 and the reinforcing bar 120 are disposed in the balcony slab S, a heat insulating material is formed to have a predetermined size, and the main reinforcing bar 110 and the reinforcing steel bar 120, The slab insulator 200 is inserted into the concrete G, and then the concrete is buried in the concrete 300. In this way, the balcony slab S is provided with a thermal insulation material having a low thermal conductivity instead of the concrete having a high thermal conductivity, so that the overall thermal conductivity of the balcony slab S can be lowered and the heat loss through the balcony slab S can be reduced.

A variety of slab insulation materials 200 may be used for the balcony slabs S. For example, various insulation materials such as expanded polystyrene, foamed insulation, and polyphenol may be used.

Meanwhile, the area of the upper surface 200a of each slab insulating material 200 may be larger than the area of the lower surface 200b. The reason why the upper surface 200a of each slab insulating material 200 is formed wider than the lower surface 200b is that when the concrete 300 is hardened by forming the formwork and the concrete 300, ) From falling downward. In this embodiment, the lower surface 200b is narrower than the upper surface 200a of each of the slab insulating materials 200, and a longitudinal section thereof has a trapezoidal shape. However, the shape of the slab insulating material 200 used in this embodiment Is not limited to a trapezoid. In addition, each of the slab insulating materials 200 may be fixed to have a predetermined gap between the main reinforcing bars 110 and the reinforcing bars 120. A tie or a spacer for fixing the slab insulation 200 to the main reinforcing bar 110 or the reinforcing bar 120 may be used. By doing so, it is possible to prevent the position of the slab insulating material 200 from being changed when the concrete is laid in the future formwork.

On the other hand, it is preferable that the height of each slab insulating material 200 is formed to be not less than 1/2 of the thickness of the balcony slab S, respectively. The thickness of the balcony slab S is generally 200 mm or more. In order to increase the heat insulating effect of the slab insulating material 200, it is preferable to use a slab insulating material 200 of 100 mm or more.

On the other hand, in order to enhance the heat insulating effect of the slab insulating material 200 installed on the balcony slab S, a plurality of slab insulating materials 200 arranged on the balcony slab S are disposed on the side closest to the outer wall 10 forming the balcony The slab heat insulating material 201 installed on the outer wall 10 can be installed in close contact with the heat insulating material 20 provided inside the outer wall 10. A heat insulating material 20 is provided on the outer wall 10 forming the boundary between the outer space and the balcony. In this embodiment, the heat insulating material 20 is provided in the form of an inner heat insulating material, It seemed to be installed.

At this time, a heat insulating material 20 provided inside the outer wall 10 and a plurality of slab insulating materials 200 disposed on the balcony slab S include a slab insulating material 201 are brought into close contact with each other, it is advantageous to prevent heat loss through the balcony slab S.

When the balcony slab S having such a structure is completed, a bottom insulating material 210 and a ceiling insulating material 220, which contact the upper and lower surfaces of the balcony slab S, respectively, are installed. At this time, the slab insulation 200 and the ceiling insulation 220 are in close contact with each other. As such, the slab insulation 200 and the ceiling insulation 220 are brought into close contact with each other, thereby effectively interrupting the heat bridge through the balcony slab S.

On the other hand, in order to further improve the insulation structure of the balcony, it is possible to install insulation on the side wall of the room on the balcony.

Next, a description will be made of a construction method for constructing a balcony insulation structure for the above-mentioned bridging.
