Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel structure and a panel material having improved heat insulation and workability, which are useful for heat insulation of an outer wall of a building such as a wooden house.

[0002]

2. Description of the Related Art Tiles are attached to the walls of buildings, particularly exterior walls such as concrete walls, through mortar. This work of sticking the tiles needs to be performed while keeping the tiles in order in the vertical and horizontal directions while maintaining smoothness, and requires skill. On the other hand, with the decrease in the number of tile craftsmen, a ceramic panel with ribs, an aluminum panel with ribs, and the like have been proposed as a relatively simple tiling method that does not require mortar coating. These panels are used as tiled outer wall base material, and after attaching the panel to the outer wall base material,
It is used to lock tiles with ribs and fix them with adhesive.

[0003] Japanese Patent Publication No. 62-6988 discloses that an adhesive such as mortar is applied to a sticking surface of an extruded panel in which a groove is formed, and the adhesive is filled in the groove. It describes that a pair of projections are fitted into adjacent concave grooves and pressed to obtain a tile-attached panel. In such a panel, the workability of the tile can be improved. However, it is difficult to significantly improve the workability of the tile because it is necessary to straddle the protrusion of the tile in the adjacent groove.

Japanese Utility Model Laid-Open Publication No. 49-6628 discloses a heat insulating tile wall in which a synthetic resin plate in which tiles are bonded and fixed in grooves formed by a lattice frame and a foamed styrene board are bonded. Japanese Patent Application Laid-Open No. 4-350250 discloses a tile in which a base plate is attached and covered on the surface of an ALC panel on which a ridge is formed, and a recess on the back surface of the tile is fitted to the ridge covered with the base plate. A mounting substrate is disclosed. Japanese Patent Application No. 4-247155 discloses a construction structure of a tile in which a base plate having a hook portion is attached to an ALC panel, and an engaging portion on the back surface of the tile is engaged with the hook portion of the base plate. I have. Further, in JP-A-63-265064, a channel bar is attached to a panel at equal intervals,
It has been proposed that bricks are fitted into channels formed between the channel bars and fixed with an adhesive such as mortar. This document describes an example in which a synthetic resin sheet having ribs corresponding to a channel bar and a heat insulating foam are laminated. Japanese Patent Application Laid-Open No. 8-284362 discloses a heat-insulating board, an air-tight sheet formed with a large number of parallel bulging elastic ribs bonded to the board, and a heat-insulating sheet as a wall structure for insulating a wall space in a highly airtight manner. A tile fitted with a tile fitted in a tile fitting groove defined by an elastic rib, a mortar joint connecting and fixing the tile in the vertical and horizontal directions, and a heat insulating tile wall provided with a heat insulating material filled and arranged in a wall space. It has been disclosed.

[0005] In such a panel, the workability of the tile can be greatly improved. However, it is necessary to stick the sheet having the ribs over the entire surface of the heat insulating material, which increases the cost. In addition, in this panel and the outer wall structure, since the fire protection depends only on the heat insulation of the tile, the heat is directly transferred to the foamed heat insulating material together with the heating of the tile by a flame or the like, and the heat insulating material disappears or shrinks, and the heat insulating property is lost. And greatly reduces fire protection.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an outer wall heat insulating panel having high heat insulation and a structure using this panel, in which tiles can be easily and efficiently constructed. Another object of the present invention is to provide an outer wall heat insulating panel which has high heat insulating properties, heat shielding properties and fire resistance and is useful for forming the outer wall of a building (particularly a building such as a wooden house) and a structure using this panel. To provide.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to achieve the above object, and have found that a rib portion is formed on at least a panel material formed of a heat insulating board without using a base material or a sheet material. When formed, the tile material is locked or hooked on the rib portion, or the tile material is fitted into the groove (recess) between the rib portions, so that the workability of the tile can be improved with an inexpensive structure, and the panel material is thermally insulated. The present inventors have found that the heat shield and the fire resistance can be greatly improved by using a laminated board composed of a board and a heat shield board, and completed the present invention. That is, the outer wall insulation panel structure of the present invention is disposed on the outer wall surface of a building,
Further, it includes a panel material formed of at least a heat insulating board, a rib portion formed on the panel material, and a tile material provided on the rib portion and fixed to the panel material.

Is joined to. An interior material 13 is attached to the indoor side of the building (in this example, inside the pillars 10 and the studs 11).

Further, a fitting portion 6 (formed in this example by a displacement between the heat insulating layer 2 and the heat shielding layer 3) is provided at an end of the panel material 1 composed of the heat insulating layer 2 and the heat shielding layer 3. A joint structure composed of steps) is formed.

A rib portion 5 protruding or protruding.
Is provided with a tile material 7, and is fixed to the heat shield layer 3 with an adhesive. Further, a joint portion 8 is formed at a peripheral portion of the tile material 7, and the joint portion is filled with mortar.

More specifically, in this example, the heat insulating layer
Extruded polystyrene foam board of B3 grade specified in JIS A-9511 (thickness: 40 mm), the heat shield layer is constituted by a calcium silicate board (thickness: 12 mm) as an inorganic board, and the rib portion is formed by cutting the inorganic board. Four circular saws each having a width of 1.5 mm are stacked and grooved, a plurality of grooves (width 6 mm, depth 5 mm) are formed in parallel at intervals of 70 mm, and a slate plate (thickness 6 mm, width 10 mm) is formed in each groove. And projecting 5 mm from the surface of the inorganic board. In addition, the polystyrene foam board and the inorganic board with ribs are joined together with a vinyl acetate emulsion adhesive to form a composite. It is arranged and fixed by driving a 90 mm long nail through a circular seat plate (diameter 25 mm) at a predetermined pitch. That is, the polystyrene foam board is pressed and fixed to the wall surface from the surface of the ribbed inorganic board with the circular seat plate. Furthermore, fitting parts (conformity structure) 6 are formed at the four ends of the panel material composed of the polystyrene foam board and the inorganic board with ribs, so that adjacent panel materials can be connected to each other in an airtight manner. It is.

The tile material (long piece length 210 mm, short piece length 60 mm, thickness 14 mm) is a porcelain tile of a joint filling type. After a modified silicone adhesive is applied linearly to an inorganic board, the tile is ribbed. It is locked or hooked to the part and is bonded to the inorganic board with an adhesive. Also,
Joints are formed in the vertical and horizontal directions of the adjacent tiles. In the joints, the joint mortar is placed at a central part of the height of the tile by one.
The joints are formed by applying the coating in a concave shape that is as low as about mm. For this reason, joints made of mortar are formed in the vertical and horizontal directions between the tiles, and the joints are integrally connected and fixed by the joints to form an inorganic board having high rigidity.

When the panel material 1 is used, the heat insulating layer 2
By utilizing the fitting portion 6 (joint joint structure) on the end face of the heat shield layer 3, not only the assembling connection efficiency and construction efficiency of the adjacent panel material 1 but also the heat insulation and airtightness can be improved.
Further, an outer heat insulating tile outer wall panel excellent in sound insulation can be formed by the mass effect of the heat insulating layer (inorganic board) integrated with the tile material and the joint mortar. The rib 5
Is formed so as to protrude or protrude in a protruding manner, so that the positioning of the tile material 7 is easy, and the ribs 5 of the heat shield layer 3 can be used as locking portions for the tile material 7. Without necessity, the tile members 7 can be easily and regularly attached using the arranged rib portions 5 as a mark or an index. In addition, the falling of the tile material 7 can be prevented by the locking and the bonding with the adhesive. In particular, the heat shielding layer 3
Is interposed between the tile material 7 and the heat insulating layer 2, so that even if the tile material 7 is heated by a fire or the like, the heat shielding layer 3
Thereby, heat transfer from the tile material 7 to the heat insulating layer 2 can be suppressed, and fire prevention can be greatly improved. For example, in the panel structure, a third-class heating test specified in JIS A1301 is passed, and the spread of fire can be prevented as in the case of the earthen wall. That is, the heat insulating layer 2, the heat shielding layer 3, and the tile material 7 can constitute a fire protection layer having high fire protection performance.

The heat-insulating layer may be made of various heat-insulating boards, for example, fibrous heat-insulating materials (such as glass fibers).
Expanded polyurethane resin (especially hard polyurethane resin), expanded polyisocyanurate resin, expanded styrene resin (expanded polystyrene, etc.), expanded phenolic resin (expanded phenolic resin, expanded urethane expanded phenolic resin, etc.), expanded foam containing reinforcing agent Resin board [foamed resin containing powdery and granular reinforcing agent (foamed resin containing calcium carbonate such as expanded polystyrene resin containing calcium carbonate), foamed resin containing fibrous reinforcing agent (containing glass fiber such as polyisocyanurate foam board containing glass fiber) It is advantageous to use a foamed resin. A preferred heat-insulating layer is a rigid foam board excellent in heat insulation, for example, a styrene resin foam board, a rigid polyurethane foam board,
It can be composed of a polyisocyanurate foam board, a phenol resin foam board, a urethane-modified phenol resin foam board, or the like.

The foam constituting the heat insulating layer may be either a closed-cell foam or an open-cell foam, but the closed-cell foam is advantageous from the viewpoint of mechanical strength. The foam may be a laminate of the foam. The foam may be a foam obtained by extrusion foaming or bead foaming, but an extruded foam is advantageous in terms of mechanical strength and the like.

The density of the heat insulating layer can be selected within a range where the weight can be reduced without impairing the mechanical strength and the like.

The thickness of the heat-insulating layer can be selected according to the desired heat-insulating properties, for example, 20 to 120 mm (for example, 20 to 110 mm).
mm), preferably in the range of about 20 to 100 mm, and usually 20 to 70 mm, especially 20 to 50 mm.
mm.

In the panel material, the heat shielding layer is not always necessary, and may be constituted by at least a heat insulating layer (heat insulating board) alone, and a rib portion may be formed on the heat insulating layer. FIG.
FIG. 4 is a schematic perspective view showing another example of the panel material of the present invention.

The panel member 21 includes a heat insulating layer 22 made of a foam and a rib portion 25 formed on the surface of the heat insulating layer in a lateral direction. Are formed (a joint structure). The ribs 25 are formed by forming grooves in the heat-insulating layer 22 in the horizontal direction and at predetermined intervals in the vertical direction, and fitting and bonding plates to these grooves. ing.

More specifically, in this example, the heat insulating layer
It is composed of a B3 grade extruded polystyrene foam board (thickness: 45 mm) specified in JIS A-9511, and the ribs are formed by cutting the foam board and stacking four circular saws having a width of 1.5 mm. A plurality of grooves (width 6 mm, depth 10 mm) are formed in parallel at intervals of 70 mm, and a slate plate (thickness 6 mm, width 15 mm) is fitted into each groove, and is formed by projecting 5 mm from the foam board surface. I have. The foam board is disposed and fixed to the shaft member constituting the wall space frame by driving a screw nail having a circular seat plate at a predetermined pitch in the same manner as described above. Furthermore, fitting parts (conformity structure) are formed at the four edges of the panel material made of the foam board,
Adjacent panel materials can be connected to each other in an airtight manner.

The tile material (long piece length 210 mm, short piece length 60 mm, thickness 14 mm, depth of the concave part on the back side 5 mm) is a porcelain tile of a joint filling type, and is a linear modified silicone adhesive on a foam board. After the application, the tiles are locked or hung on the ribs and adhered to the foam board with an adhesive. In addition, joints are formed in the vertical and horizontal directions of the adjacent tiles, and joints are formed in the joints by applying joint mortar in a concave shape whose central portion is lower than the height of the tile by about 1 mm. For this reason, joints made of mortar are formed in the vertical and horizontal directions between the tiles, and the joints are integrally connected and fixed by the joints to form an inorganic board having high rigidity. When the panel member 21 is used, the assembly efficiency, the construction efficiency, and the heat insulation / airtightness of the panel member 21 can be improved by using the fitting portion 26 on the end surface of the heat insulating layer 22 as described above. Further, since the tile material and the joint mortar are integrated to form the inorganic board, the sound insulation can be enhanced by the mass effect. In addition, by using the ribs 25, the tiles can be easily aligned, and the tiles can be easily and regularly attached without any skill, using the arranged ribs 25 as marks or indices. In addition, the falling of the tile material can be prevented by the locking and the bonding with the adhesive.

When the panel is constituted only by the heat insulating layer, the heat insulating layer may be a laminate of a plurality of heat insulating boards. As the heat insulating board, the same board (fibrous heat insulating material or foam board) as described above can be used, but at least one heat insulating layer is made of a hard foam board excellent in heat insulating property (especially high heat resistance) as described above. (Hard foam board). Examples of the hard foam board having high heat resistance include a foam board having the above-described organic heat-shielding layer. Examples of the laminate composed of a plurality of heat insulating boards include a laminate of a foamed styrene-based board having high heat insulation properties and a hard foam board having high heat resistance.
More specifically, polystyrene foam boards (eg,
A phenolic resin foam board or a polyisocyanurate resin foam board (for example, a thickness of 15 mm).
mm) with an epoxy-based adhesive. Such a composite board, in the construction,
It is preferable that a foam board having high heat insulation (foamed styrene-based board or the like) be located on the indoor side and a foam board having high heat resistance be located on the outdoor side.

When the heat insulating layer is formed of a polystyrene resin foam board or the like, the infiltration of moisture into the room can be suppressed due to the moisture resistance of the heat insulating layer, but an airtight sheet (moisture proof sheet) is provided on at least one surface of the heat insulating layer. When the layers are stacked, intrusion of moisture can be reliably prevented. In this case, the moisture-proof sheet can be interposed at an appropriate place such as between layers constituting the panel material or on the front and back surfaces, and may be provided on at least one surface of the heat insulating layer or the heat shielding layer. In many cases to prevent moisture from entering the room.

Examples of the moisture-proof sheet include various materials having a moisture-proof property (airtightness), for example, moisture-proof paper, moisture-proof cloth, olefin resin film or sheet (polyethylene film, polypropylene film, etc.), polyester resin film or sheet. (Polyethylene terephthalate film and the like), metal foil and sheet (aluminum foil and the like), composite film and sheet (aluminum-deposited polyethylene film, aluminum-deposited polypropylene film and the like) and the like. The thickness of the moisture-proof sheet is not particularly limited, and is, for example, 0.01 to 0.5 mm, preferably 0.05 to 0.3 mm, and more preferably 0.10 to 0.5 mm.
It is about 0.15 mm.

The end face of the adjacent panel material among the heat insulating layer and the heat shielding layer may be a smooth surface which can abut against each other, but forms a fitting portion (real joint structure, joint structure, etc.) It is advantageous to improve airtightness as well as assembly and connection efficiency and construction efficiency of adjacent panel materials. In particular, when a small-sized panel material is used, it is preferable to employ such a fitting structure because the number of connection portions is increased and airtightness is likely to be reduced. The structure of the fitting portion is not particularly limited as long as airtightness can be maintained. However, in many cases, actual processing or consensus processing is performed, and the fitting portion is configured with an uneven portion or a cutout portion (a cutout step portion or the like). Further, the fitting portion may be formed on at least one of the heat insulating layer and the heat shielding layer, as described above,
You may form by the step part formed by adjusting the position of the end surface of a heat insulation layer and a heat shielding layer relatively. In order to closely abut adjacent panel members, it is advantageous to form the fitting portion at least at the end (or end face) of the heat insulating layer (particularly, the heat insulating material formed of a foam).

When the panel material is applied to the outer wall by abutting or fitting the end faces, a sealing material such as an airtight tape (adhesive airtight tape or the like) is attached to the surface of the connecting portion of the adjacent panel material. It may be worn to improve airtightness.

Further, for laminating the heat insulating layer and the moisture-proof sheet, a double-sided adhesive tape, various adhesives, for example, an acrylic adhesive, a vinyl acetate adhesive, an ethylene / vinyl acetate adhesive, a rubber adhesive can be used. Alternatively, an adhesive, an epoxy-based adhesive, a urethane-based adhesive, a silicone-based adhesive, or the like can be used, and the adhesive may be in the form of an emulsion.

The heat shield layer can be formed of various organic or inorganic materials having high heat resistance and fire resistance, especially heat resistant materials having a heat resistance of 80 ° C. or more (preferably 100 ° C. or more). The organic heat shielding layer is made of a heat-resistant organic board, for example, the above-mentioned rigid polyurethane foam board, polyisocyanurate foam board, phenol resin foam board (including urethane-modified phenol resin foam board), and reinforcing agent-containing foam resin board ( A fiberboard which may be laminated on at least one surface with a moisture-proof layer such as a foamed resin board containing calcium carbonate, a polyisocyanurate-based foamed board containing glass fiber, and a fiberboard (polyethylene film, aluminum foil, aluminum-deposited polyethylene film, etc.). Plate). These organic thermal barrier layers may be used in combination of two or more.

The inorganic heat-shielding layer is made of a heat-resistant inorganic board, for example, a vitreous laminate (volcanic vitreous multilayer board, etc.),
It can be formed of a slate plate, a calcium silicate plate, a slug gypsum plate, a cement board (a cement board which may contain a reinforcing agent such as a wood wool cement board, a wood chip cement board, and a pulp-containing cement board). These inorganic thermal barrier layers can also be used in combination of two or more. The heat shield layer may be a single layer or a plurality of layers, and the plurality of heat shield layers may be a composite layer having an organic heat shield layer and / or an inorganic heat shield layer. Examples of such a composite layer include, for example, a laminate of an inorganic thermal barrier layer (such as a fiber board) and an organic thermal barrier layer (such as a polyisocyanurate-based foam board).

The thickness of the heat shield layer is within a range where heat transfer from the tile material can be effectively prevented without impairing lightness, for example, 3 m.
m or more (for example, 3 to 40 mm), preferably 5 mm or more (for example, 5 to 30 mm), more preferably 5 to 2
0 mm (for example, 6 to 18 mm), and 3 to 1
It may be about 2.5 mm.

The size of the panel material is not particularly limited, but the basic size is a width of 910 to 1000 mm and a length of 910 to 3000 mm (preferably 1000 to 300 mm).
0 mm, especially about 1500 to 3000 mm).

It is preferable that the heat insulating layer and the heat shielding layer are laminated and integrated. Lamination of the heat insulation layer and the heat shield layer is performed using an adhesive (double-sided adhesive tape, rubber-based adhesive, epoxy-based adhesive,
Adhesion using a urethane-based adhesive or the like or sewing using a suture (a polyester-based, polypropylene-based, or carbon fiber-based thread) can be performed. In addition, suture is
In many cases, it is performed on a composite layer in which a heat insulating layer and an organic heat shielding layer are combined.

The shape of the rib portion protruding from the heat shielding layer is not limited to the plate shape shown in the drawing, but may be various shapes,
For example, a triangular cross-section, a quadrangular cross-section, a trapezoidal cross-section, an inverted trapezoidal cross-section, a curved cross-section, etc. The rib portion is formed by bonding the concave groove and the rib member to each other with a fitting means such as a dovetail groove fitting between the concave groove formed in the heat shield layer and the rib member, and using the same adhesive as necessary. It may be formed, or may be integrally formed of a material having the same quality as the heat shielding layer (for example, integrally formed by extrusion, welding, or the like).

The rib member can be formed of an organic or inorganic material. For example, an inorganic plate material [a slate plate, a calcium silicate plate, a slug gypsum plate, a cement plate, a cement plate containing a reinforcing agent (a wood wool cement plate, a wood chip cement plate) , Pulp-containing cement boards, etc.)], organic board materials (polystyrene foam,
(The above-mentioned foams such as polyisocyanurate foams and phenol resin foams, and non-foamed plastic boards). When the rib portion is formed by the rib member fitted or attached to the concave groove, the width of the concave groove (and the thickness of the rib member)
Can be usually selected from a range of about 3 to 12.5 mm. In addition, the depth of the concave groove can be selected within a range that firmly holds the rib portion and does not impair the strength of the panel material.
When it is about 10 mm and the heat insulating layer and the heat shield layer are laminated, the depth of the concave groove may be larger than the thickness of the heat shield layer (for example, about 3 to 20 mm). In addition, the groove | channel of the said heat-shielding layer can employ | adopt the conventional method, for example, the cutting-out method with a digging machine, a single or several circular saw blades, etc.

The arrangement of the tile material with respect to the ribs may be a locking or locking form as shown in the figure, or a fitting form between the ribs. Further, the height of the rib portion can be selected according to the thickness of the tile material and the mode of attachment and fixation of the tile material (for example, locking, hooking, fitting form), for example, 1 to 15 mm (for example, 1 to 15 mm). 10 mm), preferably about 3 to 15 mm (particularly about 3 to 10 mm).

The ribs can be regularly scattered or formed continuously according to the shape and size of the tile material. In particular, the rib portions are scattered or continuous in the lateral direction of the panel material and are formed substantially in parallel. That is, the rib portions extend in the horizontal direction of the panel material in a linear or dot-like manner, and are formed substantially parallel to each other and at substantially equal intervals in the vertical direction. When a rectangular tile is attached and fixed with the long axis in the horizontal direction, the rib portion is determined in consideration of the length of the tile in the short axis direction and the width of the joint portion (that is, the length of the short side of the tile material + It can be formed substantially parallel (at intervals of the sum of joint widths).

As the tile material, conventional tiles (for example, earthenware tiles, ceramic tiles, clay tiles, porcelain tiles, etc.), bricks (building bricks, etc.) and the like can be used. As the tile material, a joint filling type tile can be used when jointing is performed, and a brick type tile can be used when jointing is not performed.

The tile material is attached to the rib portion with an adhesive while being hooked or locked on the rib portion, or the tile material is arranged in a concave groove (lateral groove) formed between the rib portions. Tiling can be easily performed by attaching or fitting and attaching with an adhesive. When sticking the tile material to the inorganic thermal barrier,
Applying an adhesive (epoxy-based adhesive, silicone-based adhesive, etc.) to the inorganic heat-shielding layer and attaching the tile material is effective in improving the adhesiveness. In addition, when mortar is provided at the joint after the tile material is attached, an adhesive (acrylic adhesive, vinyl acetate, etc.) is applied to a portion of the inorganic heat-insulating layer corresponding to the portion where the mortar is provided (joint). When an adhesive such as an adhesive or an ethylene-vinyl acetate adhesive is applied, it is effective to improve the adhesiveness between the mortar at the joint and the inorganic thermal barrier layer.

In the case of a wooden house frame, the panel material is usually applied to the outer surface (wall space) of a pair of left and right columns, eaves girder, body difference, or a pair of upper and lower horizontal members on the base. ). It is preferable that the panel material be fixed to the frame (shaft) with nails to improve workability and fixing stability. When fixing the panel material with a nail, it is effective to improve the fixing stability by passing the nail through the center of a washer (for example, a circular washer having a diameter of 15 to 50 mm). The driving depth of the nail into the pillar can be appropriately selected, for example, 20 to 60.
mm, preferably about 30 to 40 mm.

Intermediate members include plywood (structural plywood, water-resistant plywood, etc.), inorganic or organic board materials (slate board, calcium silicate board, slug gypsum board, polyisocyanurate foam board, phenolic resin foam board, calcium carbonate foam board, etc.) Etc. can be used. The thickness of the intermediate member can be selected according to the desired strength and the like, and is usually about 4.5 to 12.5 mm. When fixing the plate-shaped intermediate member or plate-shaped composite to the work site during construction, airtightness with moisture-proof properties such as urethane foam sheet, ethylene-propylene foam sheet, polyethylene foam sheet, polypropylene foam sheet, etc. The presence of an elastic sheet is useful for improving airtightness.

The tiles can be constructed by bonding and fixing the tiles to the ribs and filling the joints between the tiles with mortar. To bond the tile material, use an adhesive (epoxy adhesive, silicone adhesive, etc.)
The tile material is applied to at least one of the rib portion corresponding to the arrangement portion of the tile material and the back surface of the tile material, the tile material is attached to the rib portion by a method such as locking, latching, fitting, or the like, and the rib portion and the adhesive are bonded. This can be performed by bonding and fixing the peripheral portion and the tile material. By such adhesive fixing, the tile materials can be connected and fixed in the vertical and horizontal directions.

The type of mortar at the joint is not particularly limited, and a commercially available joint mortar can be used. The filling amount of the mortar into the joint is 50 times the thickness (height) of the tile material.

A plurality of panel members are usually provided adjacent to the outside of the wall surface of a building such as a wooden house. A ventilation layer may be formed by interposing a spacer (body edge such as a vertical body edge) between the heat insulation layer (polystyrene foam board or the like) and the heat shield layer (rib-added calcium silicate board or the like). . In this case, the heat insulating layer, the spacer and the heat shielding layer may be integrated. In such a structure, the outside of the building can be covered with a heat insulating layer, and the ventilation layer can be used to allow air to pass upward, to discharge moisture, and to make the heat from the tile outer wall heated by the solar radiation to the heat insulating layer. It is effective for reducing heat radiation. In addition, when arranging a spacer such as a body edge, the depth of the groove formed in the panel material may be about 3 to 10 mm. In this structure, a heat insulating layer (such as a polystyrene foam board) is temporarily fastened to a wall space frame with a nail, and square wood (21 mm × 4 mm) is formed on pillars and studs.
After fixing the vertical waist edge (e.g., 5 mm) with a nail, a heat-insulating layer with ribs (calcium silicate board or the like) is fixed to the waist edge with a nail.

The present invention can be applied to various buildings, especially houses (for example, steel frame houses (ie, steel houses), wooden houses, etc.), and the houses are RC-constructed houses, RM (reinforced concrete masonry) houses. It may be. When the external heat insulation method according to the present invention is applied to a building whose frame is made of steel, it is effective in avoiding condensation due to a heat bridge.
