Description

  The present invention relates to a residential multiple heat-insulating structure used for a wall material and a roof base material of a house.

In recent years, in order to obtain a more comfortable living environment, various heat treatments have been applied to each part of the house.
In particular, since the wall materials and roofs of houses are the places where the sun is often exposed and the temperature rises most easily, in order to spend comfortably indoors in the summer, heat insulation treatment is applied to the wall materials and the roof to increase the cooling efficiency. is important.

  As such, a heat shield structure related to the wall material 10 as shown in FIG. 7 is disclosed (for example, see Patent Document 1).

  However, particularly in the summer, the heat insulating material 12 itself accumulates and rises in temperature due to the heat of the sun, so that heat is re-radiated from the heat insulating material 12 to the indoor side P, resulting in an increase in the indoor temperature. Of course, even if the temperature of the heat insulating material 12 is increased, the room temperature is far lower and the efficiency of cooling is higher than the case where the heat insulating material 12 is not provided. There is room for improvement.

According to the multiple thermal barrier structure for a house according to claim 1 of the present invention, since the thermal barrier coating is applied to the outdoor side surface or the outdoor side of the heat insulating material, the heat from the sun in the summer heats the outdoor side of the thermal insulating material. As a result, the temperature rise of the heat insulating material itself is suppressed, and the heat reradiated from the heat insulating material to the indoor side can be reduced. In other words, since heat can be doubled by the heat-shielding paint and heat-insulating material on the outdoor side, the heat-insulating (heat-shielding) efficiency is high, and when the wind enters from the window, the cooling is unnecessary even in summer. Can be prevented. Even if cooling is necessary, the cost of cooling can be greatly reduced.
In addition, the amount of heat radiated from the human body in the room is greater than the amount of heat radiated from the walls and ceiling, so that the temperature can be felt cool even in summer and the room can be comfortably spent indoors.

In addition, since the thermal barrier paint is applied to the exposed surface of the heat insulating material, the heat of the indoor material due to heating is blocked from moving from the indoor side to the outdoor side of the heat insulating material in winter, so that the heat insulating material itself Is suppressed, and the heat reradiated from the heat insulating material to the outdoor side can be reduced. That is, since the heat can be doubled by the indoor heat insulating paint and the heat insulating material, the heat insulating efficiency is high and the heating cost can be reduced. Also, condensation can be prevented.
At the same time, the temperature of the walls and ceiling rises, and the difference between the amount of heat radiated from the human body in the room and the amount of heat radiated from the walls and ceiling is reduced, so that the perceived temperature can be reduced even if the room temperature is low in winter. You can spend comfortably indoors without being lowered.

Moreover, according to the multiple heat insulation structure for houses according to claim 2, since the heat shielding paint is applied to the outdoor side surface or the outdoor side of the heat insulating material, the heat from the sun in the summer from the outdoor side of the heat insulating material. By blocking the movement to the indoor side, the temperature rise of the heat insulating material itself is suppressed, and the heat reradiated from the heat insulating material to the indoor side can be reduced. That is, since heat can be doubled by the heat-shielding paint and heat-insulating material on the outdoor side, the heat insulation efficiency is high, and when the wind enters from the window, it is possible to prevent an increase in room temperature, such as no need for cooling even in summer. . Even if cooling is necessary, the cost of cooling can be greatly reduced.
In addition, since the amount of heat radiated from the human body is larger than the amount of heat radiated from the walls and ceiling, the temperature can be felt cool even in summer, and it can be comfortably spent indoors.

In addition, since the thermal barrier paint is applied to the indoor side surface of the inner plate material, the heat of the indoor room due to heating is blocked from moving from the indoor side of the inner plate material to the outdoor side in winter, so that the heat insulating material itself The temperature rise is suppressed, and the heat reradiated from the heat insulating material to the outdoor side can be reduced. That is, since the heat can be doubled by the indoor heat insulating paint and the heat insulating material, the heat insulating efficiency is high and the heating cost can be reduced. Also, condensation can be prevented.
At the same time, the temperature of the walls and ceiling rises, and the difference between the amount of heat radiated from the human body and the amount of heat radiated from the walls and ceiling becomes small. You can spend a comfortable time there.

  These effects can be obtained by using any of a board-like material (Claim 3), cotton-like rock wool or glass wool (Claim 4) as the heat insulating material.

  Moreover, according to the multiple heat-insulating structure for a house according to claim 5, a space is formed between the heat insulating material and the outer plate material by arranging the heat insulating material apart from the outer plate material, Since the air gap in the wall material communicated with the air gap in the roof base material at the upper end of the wall material, the air in the air gap in the wall material and the air in the air gap in the roof base material, which are reduced in density by heating, are the air gap in the roof base material. It becomes possible to exhaust to the outside through an exhaust port provided in the roof via Therefore, since the heated air does not stay in the space of the wall material or the space of the roof base material, the heat insulating material adjacent to the space is more difficult to store heat, and the heat insulating effect is further enhanced.

  In addition, the point which apply | coats a thermal-insulation coating to both the indoor side and the outdoor side of a heat insulating material like the multiple heat insulation structure for houses of this invention is not described at all in the patent document 1 mentioned above.

With reference to FIG. 1 thru | or FIG. 6, the multiple heat insulation structure for houses which concerns on embodiment of this invention is demonstrated.
As shown in FIG. 1, this residential multiple heat insulating structure is used for a wall material 20 and a roof base material 30 of a house. The same parts as those shown in the conventional example are denoted by the same reference numerals.

As shown in FIG. 2, the wall material 20 includes an outer wall material 21 and a heat insulating material 22.
The outer wall material 21 is a plate material that constitutes the wall material 20 and is exposed outdoors. Since the outdoor side surface is exposed to wind and rain, waterproofing or antifouling is appropriately performed.

The heat insulating material 22 has a board shape with a substantially convex cross section, and is disposed between the adjacent studs H and on the indoor side P of the outer wall material 21. Further, the heat insulating material 22 covers and conceals the surface on the indoor side P of the stud H together with the adjacent heat insulating material 22.
The heat insulating material 22 is disposed away from the outer wall material 21, and a gap S is formed between the heat insulating material 22 and the outer wall material 21.
Further, one surface of the heat insulating material 22 is exposed to the indoor side P, and a heat shielding paint 23 is applied to the surface of the heat insulating material 22 on the indoor side P and the surface of the heat insulating material 22 on the outdoor side Q.
The thermal barrier coating 23 applied to the surface P on the indoor side P of the heat insulating material 22 has a high emissivity of 3 to 5 μm far infrared rays that are well absorbed by the human body (95%) and a small heat capacity.
Further, the thermal barrier coating 23 applied to the outdoor Q surface of the heat insulating material 22 has a high reflectance (95%) for near infrared rays (2 μm or less) and a high emissivity for far infrared rays (3 μm or more). (95%), which has a small heat capacity.

As shown in FIG. 3, cotton-like rock wool or glass wool may be used as the heat insulating material 22.
At this time, the inner plate member 25 is disposed away from the outer wall member 21 on the indoor side P of the outer wall member 21, and the heat insulating material 22 is fitted so as to be entirely accommodated between the adjacent pillars H. Is covered with the inner wall material 24. Then, a thermal barrier coating 23 is applied to the surface on the indoor side P of the inner wall material 24 and the surface of the inner plate member 25 on the outdoor side Q.

  Moreover, as shown in FIG. 4, even if it is a board-shaped heat insulating material 22, it is set as a rectangular cross section, it fits so that all may fit between the adjacent studs H, and the indoor side P may be covered with the inner wall material 24. .

The roof base material 30 includes a rafter 36, a heat insulating material 32, and a base plate 31, and is a heat insulating panel 30 for a roof base of a unit product integrated in a factory. In the description of the heat insulation panel 30 for roof foundation, the upper side is the outdoor side Q, and the lower side is the indoor side P.
As shown in FIG. 5, a plurality of rafters 36 are horizontally arranged at the same height at predetermined intervals in the left-right direction, and extend in the front-rear direction.
Further, the width of the cross section in the left-right direction is narrowed from below to above, and the side surface of the rafter 36 is defined as an upward inclined surface 36a.
However, the left side surface of the rafter 36 positioned at the left end when the roof base heat insulating panel 30 is used and the right side surface of the rafter 36 positioned at the right end when the roof base heat insulating panel 30 is used are vertical. This is to prevent a gap from being generated between the roof base heat insulation panels 30 adjacent to the left and right when the roof base heat insulation panel 30 is constructed.

As shown in FIG. 5, the heat insulating material 32 is a board-like, for example, hard urethane, and the height (thickness) is about 70% of the height of the rafter 36.
The length of the heat insulating material 32 in the front-rear direction is substantially equal to the length of the rafter 36 in the front-rear direction.
Further, the width in the left-right direction of the cross section of the heat insulating material 32 is narrowed from the upper side to the lower side, and the side surface of the heat insulating material 32 is defined as a downward inclined surface 32a.
A slit 32 b substantially parallel to the front-rear direction in which the rafter 36 extends is provided on the lower surface of the heat insulating material 32. The slit 32 b extends in the front-rear direction by the length of the heat insulating material 32. Further, the depth of the slit 32 b is substantially half of the height of the heat insulating material 32.

And the heat insulating material 32 is dropped and fitted in the state closely_contact | adhered to the rafter 36 in the lower part between the adjacent rafters 36 so that the space | gap S may be formed in the upper part between the adjacent rafters 36 among several rafters 36.
At this time, the downward inclined surface 32a of the heat insulating material 32 is opposed to the upward inclined surface 36a of the rafter 36. Further, the lower surface of the rafter 36 and the lower surface of the heat insulating material 32 are flush with each other.
Here, the left and right widths of the heat insulating material 32 may be slightly wider than the distance between the adjacent rafters 36 and may be press-fitted when the heat insulating material 32 is fitted between the rafters 36. The left and right widths may be made equal to the distance between the adjacent rafters 36 so that the bottom surface of the rafters 36 and the bottom surface of the heat insulating material 32 are flush with each other due to the weight of the heat insulating material 32.
Further, a thermal barrier coating 33 is applied to the upper and lower surfaces of the heat insulating material 32.
Further, an airtight tape 37 is attached from the side surface of the rafter 36 to the upper surface of the heat insulating material 32 so as to cover the boundary between the rafter 36 and the heat insulating material 32.

The field board 31 is a single board placed on the rafter 36.
The left and right widths of the field board 31 are substantially equal to the distance between the left side of the rafter 36 at the left end and the right side of the rafter 36 at the right end of the thermal insulation panel 30 for roof foundation, but as shown by the two-dot chain line in FIG. The field board 31 is attached to the rafter 36 and the heat insulating material 32 so that the right end of the field board 31 in the roof base thermal insulation panel 30 adjacent to the left side of the left half of the left edge rafter 36 can be mounted. The rafter 36 is mounted on the rafter 36 while being shifted to the right by half the width of the rafter 36 and fixed with a nail or the like.

The heat insulating panel 30 for the roof base thus constructed is attached to the eaves girder (not shown) from the purlin 101 via the purlin 102 so that the rafters 36 are orthogonal to the purlin 101 and the purlin 102.
At this time, as shown in FIG. 1, the space S of the wall material 20 communicates with the space S of the roof base material 30 at the upper end of the wall material 20, and the air in the space S of the wall material 20 is made to pass through the air gap S of the roof base material 30. The air can be exhausted to the outside through an exhaust port 35 provided in the roof.

According to the residential multiple heat shield structure configured as described above, since the heat shield paints 23 and 33 are applied to the surfaces of the heat insulating materials 22 and 32 on the outdoor side Q, heat from the sun is insulated in summer. Since the movement from the surface of the outdoor side Q of the materials 22 and 32 to the indoor side P is blocked, the temperature rise of the heat insulating materials 22 and 32 itself is suppressed and reradiated from the heat insulating materials 22 and 32 to the indoor side P. Heat can be reduced. That is, since the heat shielding paints 23 and 33 and the heat insulating materials 22 and 32 on the outdoor side Q can double heat shield, the heat insulation (heat shield) efficiency is high, and cooling is unnecessary even in summer when the wind enters from the window. It is possible to prevent an increase in room temperature. Even if cooling is necessary, the cost of cooling can be greatly reduced.
In addition, the amount of heat radiated from the human body in the room is greater than the amount of heat radiated from the walls and ceiling, so that the temperature can be felt cool even in summer and the room can be comfortably spent indoors.

Moreover, since the thermal barrier paints 23 and 33 are applied to the exposed surfaces of the heat insulating materials 22 and 32, the indoor heat due to heating moves from the indoor side P to the outdoor side Q of the heat insulating materials 22 and 32 in winter. By blocking this, the temperature rise of the heat insulating materials 22 and 32 itself is suppressed, and the heat reradiated from the heat insulating materials 22 and 32 to the outdoor side Q can be reduced. That is, since heat can be double shielded by the thermal barrier coatings 23 and 33 and the heat insulating materials 22 and 32 on the indoor side P, the thermal insulation efficiency is high and the heating cost can be reduced. Also, condensation can be prevented.
At the same time, the temperature of the walls and ceiling rises, and the difference between the amount of heat radiated from the human body in the room and the amount of heat radiated from the walls and ceiling is reduced, so that the perceived temperature can be reduced even if the room temperature is low in winter. You can spend comfortably indoors without being lowered.

  Furthermore, since the heat insulating materials 22 and 32 are spaced apart from the outer plate materials 21 and 31, a gap S is formed between the heat insulating materials 22 and 32 and the outer plate materials 21 and 31, and the wall material 20. Since the air gap S of the wall material 20 communicated with the air gap S of the roof base material 30 at the upper end of the wall material 20, as shown in FIG. The air in the air gap S of 30 can be exhausted to the outside through the air outlet 35 provided in the roof via the air gap S of the roof base material 30. Therefore, since the heated air does not stay in the space S of the wall material 20 or the space S of the roof base material 30, the heat insulating materials 22 and 32 adjacent to the space S are more difficult to store heat, and the heat insulating effect is further enhanced. .

In addition, although the heat insulating materials 22 and 32 were spaced apart from the outer side plate materials 21 and 31, and the space | gap S was provided, it is not restricted to this, Even if the heat insulating materials 22 and 32 and the outer side plate materials 21 and 31 are closely_contact | adhered. Good.
The roof base material 30 is a roof base heat insulation panel 30 which is a unit product integrated in the factory, but instead of being a unit product, the rafter 36, the heat insulating material 32, and the base plate 31 are used at the construction site. As a base of the roof, it may be installed over the purlin 101 or the main building 102 in order.

Further, the roof base material 30 may be various forms other than the present embodiment, similarly to the wall material 20, and may be provided with a plate material below the heat insulating material 32 (inside the room P), or the base plate 31. The gap S may not be provided between the heat insulating material 32 and the heat insulating material 32.
Moreover, although the rafter 36 and the heat insulating material 32 of the roof base material 30 are trapezoidal in cross section, they may each be rectangular in cross section.

Moreover, although the house provided with the roof with an inclination was demonstrated, it is not restricted to this, Even if it is a roof without an inclination, an exhaust port is provided and the inside in the space | gap S, such as the wall material 20, was heated from there Air can be discharged.
Moreover, the thermal barrier coatings 23 and 33 on the indoor side P and the thermal barrier coatings 23 and 33 on the outdoor side Q may be the same type of thermal barrier coatings or different types.
Moreover, you may stick a heat insulation sheet instead of apply | coating the thermal-insulation coating materials 23 and 33. FIG.
Further, foamable urethane foam may be used instead of cotton-like rock wool or glass wool. Moreover, you may apply | coat the heat-shielding coating materials 23 and 33 directly on the surface of this urethane foam.

  In addition, the heat shielding paints 23 and 33 are applied to the surfaces of the heat insulating materials 22 and 32 on the outdoor side Q. However, the present invention is not limited to this. Paints 23 and 33 may be applied.
