Description

High-density Insulation Board Which Is Bonded With Nonwoven Fabrics On Four Sides For Anti-condensation Of Wall And Slab Coner Areas}

In the present invention, as shown in FIGS. 3 and 4, the thermal insulation performance is performed inside the concrete section of the wall of the wall 40 or the slab 50 orthogonal to the room 20 side to the wall 30 facing the outside air and the balcony 10. In order to increase the condensation prevention effect by installing the excellent high-density insulation board 700 embedded in the interior side, and the surface exposed to the interior side of the high-density insulation board 700 to be beautifully finished with paper or painting, reinforced concrete construction After fixing the high-density insulation board 700 using the insulation fixing nail to the corner formwork of the wall 40 or the slab 50, the wall 40 after passing the process of reinforcing processing assembly, concrete placing, formwork demoulding. Or a high-density insulation board 700 is bonded to the non-woven fabric on the four sides of the present invention at the corner of the slab 50 is embedded in the concrete.

At this time, the reason for using a high density insulation board is to increase the heat resistance than the conventional composite insulation board 70 to increase the condensation prevention effect and reinforce the surface by using a non-woven fabric is excellent mechanical properties can replace the interior material effect However, if the density is small, the insulation board is consolidated due to the work load of workers, equipment, concrete, etc., and the insulation performance is reduced, or the whole or locally consolidated insulation board is restored to its original thickness after formwork demoulding, If they do not match, they will lose their function as a buried condensation preventing material.

To this end, the present invention is a non-combustible or flame-retardant high-density insulation board having excellent thermal insulation performance and mechanical properties (rock wool board of density 60㎏ / ㎥ or more: Rock Wool Board, glass wool board of density 48㎏ / ㎥ or more: Glass Wool Board, density 25㎏ / Phenolic foam board of ㎥ or more: Phenolic Foam Board, Polyisocyanate foam board of density 25㎏ / ㎥ or more: Poly Isocyanate Foam Board, Flame retardant styrofoam board of density 25㎏ / ㎥ or more Foam board: Styro Foam Board) And if the wall 30 facing the balcony 10 is installed using a heat insulating fixing nail in the vertical or horizontal direction to the heat insulating fragile site formwork at the corner of the wall 40 and the slab 50 orthogonal to the room 20 side, After reinforcing fabrication, concrete casting and formwork demoulding, the high-density insulation board 700 with non-woven fabric 710 bonded to four sides automatically matches the wall or slab surface at the corners of walls and ceilings. High density insulation board 700, which is reinforced with four sides with non-woven fabric, has excellent mechanical properties and does not require a separate interior material, and is attached to the concrete attachment surface of the high density insulation board 700. The nonwoven fabric 710 has a high adhesion performance with concrete so that there is no fear of peeling off and at the same time protects the surface of the high-density insulation board 700 to minimize damage to the high-density insulation board 700 by workers or equipment in subsequent processes. The non-woven fabric 710 on the opposite side of the high-density insulation board 700 is exposed to the wall surface or the slab surface of the room to serve as a super medium, so that the paper can be directly applied without the super medium. And a non-woven fabric 710 for preventing condensation at the corners of the slab 50 is directed to a high density insulation board 700 attached to four surfaces.

The wall 30 facing the outside air and the balcony 10 in a residential facility does not have condensation due to sufficient insulation 60 and interior 61, but the walls 40 and slabs 50 orthogonal to the interior 20 side. Is structurally connected to the wall 30 facing the outside air and the balcony 10 so that the corner portion is vulnerable to heat insulation, so that the corner portion of the wall 40 and the slab 50 orthogonal to the interior 20 side has a constant width. The condensation prevention material is to be installed, and the bottom portion of the slab 50 does not need condensation prevention construction because the floor finish 51 is constructed.

In particular, due to the lack of buffer space due to the expansion of the balcony, increase of airtightness of windows, recent strengthening of insulation standards and continuous changes in living habits, condensation prevention materials need higher performance, but concrete section defects as thick as condensation prevention materials It is impossible to increase the thickness of the condensation preventing material, and the magnesium board (or polypropylene hollow board) in the composite insulation board 70, which is a conventional condensation preventing material, was needed as an interior material for coating or painting, but the thermal insulation effect is hard to expect. As a material, the high-density insulation board 700 of the present invention can reinforce the four sides with a nonwoven fabric 710 so that the mechanical properties can be expected to have the effect of interior materials, thereby saving interior materials and adding insulation as much as its thickness. In the paper work, super badges can be reduced.

In addition, the use of non-combustible insulation or flame retardant insulation material is emerging as a result of recent heat-related insulation and accidents, but the extruded styrofoam used in the conventional composite insulation plate 70 is highly combustible and toxic gas is generated in the fire. It was provided with a high-density insulation board 700 having a performance.

Insulation weakening nails are used before placing concrete vertically or horizontally on the wall 40 and the slab 50 corners at the corners of the wall 30 facing the outside air and the balcony 10 orthogonally to the interior 20 side. Conventional composite insulation board 70 is installed by bonding the extruded styrofoam with excellent thermal conductivity and a magnesium board (or polypropylene hollow board) which is a built-in material, when the composite insulation board 70 is formed on the formwork magnesium board ( Or the polypropylene hollow board) is in contact with the formwork which becomes the interior 20 side of the wall 40 or the slab 50, and the extruded styrofoam of the composite heat insulating plate 70 is exposed to the worker direction, so as a subsequent process of reinforcing steel fabrication and concrete Workers and equipment for pouring work cause a lot of damage to the extruded styrofoam and its repair is impossible in the work process. It is installed embedded in the concrete (50).

The damage of the extruded styrofoam is the biggest performance deterioration of the condensation prevention composite insulating plate 70, and a large amount of wood powder among the components of the magnesium board, which is the interior material of the wall 40 or the slab 50, has a high condensation prevention property. Due to the high possibility of corruption, the function as an interior material is also deteriorated. The conventional condensation prevention composite insulation board 70 is used because it adheres to a magnesium board (or polypropylene hollow board) as an interior material and extruded styrofoam as a foamed synthetic resin. Even if a defect occurs, it is impossible to check, and after the composite insulation board 70 is buried, internal finishing work (dwelling, painting work, etc.) takes more than one year at most construction sites. Because of this, there is a separate decontamination cost.

In particular, in conventional residential facilities, the balcony acted as a cushioning space, which contributed to the prevention of condensation. However, in recent residential facilities, the condensation phenomenon occurs a lot due to the expansion of the balcony. Increasing the thickness of the condensation preventing material to increase the thermal insulation performance increases the deficiency of the concrete cross section of the structure, so it is inadequate to prevent the increase of condensation phenomenon with the composite insulation plate 70 which is a conventional condensation preventing material.

Prior art in this regard is a composite heat insulating plate for the corner portion of the wall for preventing condensation of the Republic of Korea Patent No. 1006435920000 (announced on November 01, 2006).

An object of the present invention is a condensation preventing material concrete installation method for installing a high-density insulating board 700 bonded to a non-woven fabric 710 on the four sides before the concrete is placed in the formwork, the four sides of the high-density insulating board 700 in the non-woven fabric Reinforced with 710, the mechanical properties are excellent, eliminating the need for a separate interior material and minimize the damage of the high-density insulation board 700 due to workers and equipment for the reinforcement assembly and concrete placing work, which is a subsequent process, the indoor (20) The nonwoven fabric 710 on the side is a high-efficiency, low-cost condensation preventing material, which is characterized in that the paper can be directly applied without super medium instead of super medium.

In addition, by having a high-density insulating board 700 having excellent thermal insulation performance and mechanical properties, even if the same thickness, the condensation prevention effect is superior to the conventional condensation preventing material and reduces damage and deformation by subsequent work, the conventional composite insulation board (70) ), The condensation prevention material of the concrete buried installation method, which can increase the heat permeation resistance by replacing the thickness of the magnesium board (or polypropylene hollow board) with insulation.

In particular, in recent years, the condensation prevention material requires higher condensation prevention performance due to the lack of buffer space due to the expansion of the balcony, the recent strengthening of the insulation standard, the increase of airtightness of the windows and the continuous change of lifestyle. In addition, in response to the recent occurrence of accidents related to frequent insulation materials and accidents due to the avoidance of synthetic resin foam products, it is equipped with a non-combustible or flame retardant condensation prevention material.

In accordance with an embodiment of the present invention for achieving the above object, a high-density insulation board (excellent heat insulation performance and mechanical properties, non-flammable or flame retardant (rock wool board density of 60㎏ / ㎥ or more: Rock Wool Board, glass surface of density 48㎏ / ㎥ or more) Board: Glass Wool Board, Phenolic Foam Board with Density 25㎏ / ㎥ or More: Phenolic Foam Board, Polyisocyanate Foam Board with Density 25㎏ / ㎥ or More: Poly Isocyanate Foam Board, Flame Retardant Styrofoam Board with Density 25㎏ / ㎥ or higher: Styro Foam Board) to improve condensation prevention performance and to adhere to four sides of the high-density insulation board 700 with a non-woven fabric 710 to reinforce the mechanical properties, and then install it in the formwork. It can minimize the deformation and damage of the high-density insulation board 700 due to the workers and equipment for, the non-woven fabric 710 of the concrete attachment surface of the high-density insulation board 700 is cone Since the adhesion performance with the litt is good, there is no fear of peeling off and at the same time, the nonwoven fabric 710 on the opposite side of the high-density insulation board 700 becomes the finishing surface of the wall 40 or the slab 50 of the interior 20. The nonwoven fabric 710 is a high density insulation board 700 is bonded to the four sides, characterized in that the non-woven fabric 710 is to act as a super medium to directly do the paper without the super medium.

The wall 40 orthogonal to the outer wall 30 by using the high-density insulation board 700 to which the nonwoven fabric 710 is adhered to the four sides of the present invention in a concrete buried installation method for installing a condensation preventing material in the formwork before the concrete is placed. When installed at the corner portion of the interior 20 side of the slab 50, it is possible to block the heat transfer from the outer wall 30 to increase the condensation prevention effect of the wall 40 or the slab 50 portion, the conventional composite Like the heat insulation board 70, it is installed in the concrete and does not require a separate construction cost, and also reinforces the four sides of the high density heat insulation board 700 with the nonwoven fabric 710 to increase the adhesive force with the concrete and at the same time high density heat insulation board on the formwork. (700) It minimizes deformation and damage by workers and equipment in the subsequent process after installation (reinforcing steel fabrication, concrete placing, formwork demoulding), resulting in high condensation prevention performance and high density insulation board (7 00) Since the non-woven fabric 710 is attached to the indoor side of the exposed surface, it is possible to do paper work without the need for a separate super medium construction.

In addition, even without a magnesium board (or polypropylene hollow board) that becomes the interior side finish surface in the conventional composite insulation board 70, the high-density insulation board 700 is reinforced with a non-woven fabric 710 because the mechanical properties can act as interior materials Magnesium boards (depending on the total imports are using 90% or more of magnesium boards with flame retardant performance rather than polypropylene hollow boards without flame retardant performance), and magnesium boards (or polypropylene) can be saved. When the insulation is added as thick as the thickness of the hollow board), there is an effect that can increase the condensation prevention performance even in the cross-sectional defect state of the conventional concrete.

In this way, it is equipped with a high-efficiency condensation prevention material that improves the condensation prevention performance, saves super medium, and reduces the import of magnesium board, thereby improving the weak part of the condensation prevention method and reducing the cost, thus helping to achieve a reasonable construction culture. In particular, in recent years, most residential facilities have extended balcony and disappeared cushioning space, which requires high-efficiency condensation prevention material, and also secures safety from fire while responding to evasion of synthetic resin foam products due to incidents and accidents caused by insulation materials. It is effective.

Secondly, when reinforced with a non-woven fabric, the mechanical properties are excellent. When the insulation board is consolidated due to the work load such as equipment and concrete, the condensation prevention performance is reduced, or when the whole or locally consolidated insulation board is restored to its original thickness after form demoulding and does not match the finishing surface of the room, This is because it loses its function as an inhibitor.
