  However, in the above conventional heat insulation structure and construction method, the mounting pin for attaching the heat insulating plate is provided in a state of connecting the front and back of the heat insulating plate, so that it becomes a thermal bridge, and the heat insulation is deteriorated or the problem that causes condensation There is.

  In recent years, the heat insulating plate tends to be thick for energy saving. In some cases, high heat insulation using a heat insulating plate having a thickness of 100 to 150 mm may be required. When such high heat insulation is required, a special long mounting pin must be prepared for mounting a thick heat insulating plate, which causes an increase in material cost. In addition, when the heat insulating plate is thick, the space between the structural member and the trunk edge is widened, and the attachment state of the trunk edge is likely to be unstable, and the attachment state of the exterior material or interior material attached to the trunk edge is unstable. There is also a problem that tends to become.

  The present invention has been made in view of the above-described conventional problems, and a heat insulating plate is attached to a structural member of a building with a mounting pin screwed or driven into the structural member, and further finished on the surface side of the heat insulating plate. In the heat insulation structure and construction method of buildings where materials are attached, it is possible to prevent thermal bridges due to mounting pins and to attach heat insulation plates without using long mounting pins even when high heat insulation is required. In addition, it is an object of the present invention to obtain a stable mounting state of the finishing material.

For the above purpose, the first aspect of the present invention is that a heat insulating plate made of a synthetic resin foam is attached to a structural member of a building with a mounting pin screwed or driven into the structural member, and further on the surface side of the heat insulating plate. In the heat insulation structure of a building with a finishing material attached to

On the structural member side, in the region where the first heat insulating plate, the face material, and the second heat insulating plate overlap, the first heat insulating plate is penetrated from above the face material and screwed or driven into the structural member. The second heat insulating plate is attached in a region where the first heat insulating plate, the face material, and the second heat insulating plate overlap each other on the surface side of the second heat insulating plate. It is provided with the heat insulation structure of the building characterized by being attached with the 2nd attachment pin screwed or struck into the said face material without penetrating the said 1st heat insulation board .

In the first aspect of the present invention, the density of the first heat insulating plate is higher than the density of the second heat insulating plate.
The composite heat insulating plate is attached to the outer surface side of a structural member that is a constituent material of a wall of a building, and the moisture permeability resistance of the face material is at least equal to or equal to the moisture permeability resistance of the first heat insulating plate. It is included as the preferable aspect that it is less than.

In the second aspect of the present invention, a heat insulating plate made of a synthetic resin foam is attached to a structural member of a building with a mounting pin screwed or driven into the structural member. In the construction method of the heat insulation structure of the building where
As the heat insulating plate, a composite heat insulating plate previously integrated with a face material sandwiched between a first heat insulating plate and a second heat insulating plate made of a synthetic resin foam, the composite heat insulating plate is used as the first heat insulating plate. With the side being the structural member side, in the region where the first heat insulating plate, the face material and the second heat insulating plate are overlapped, the first heat insulating plate is penetrated from above the face material and is first attached to the structural member After the pins are screwed or driven in, the finishing material is attached to the surface side of the second heat insulating plate in the region where the first heat insulating plate, the face material and the second heat insulating plate overlap. A construction method for a heat insulating structure of a building is provided, wherein a second mounting pin is screwed or driven into the face material without passing through the first heat insulating plate .

  In the second aspect of the present invention, the first mounting pin is screwed or driven through an insertion hole formed in the second heat insulating plate, or the head of the first mounting pin from above the second heat insulating plate. The finish after filling the hole into the insertion hole or the insertion hole formed when pushing the head of the first mounting pin to the position of the face material. The attachment of a material is included as a preferred embodiment.

Further, according to the third aspect of the present invention, a heat insulating plate made of a synthetic resin foam is attached to a structural member of a building with a mounting pin screwed or driven into the structural member, and a finishing material is further provided on the surface side of the heat insulating plate. In the construction method of the heat insulation structure of the attached building,
As the heat insulating plate, a second heat insulating plate made of synthetic resin foam is integrated on the surface of the face material of the pre-product obtained by previously integrating the first heat insulating plate made of synthetic resin foam and the face material. In the region where the first heat insulating plate, the face material, and the second heat insulating plate overlap with each other, the pre-product has the first heat insulating plate side as the structural member side. After the first mounting pin is screwed or driven into the structural member via the first heat insulating plate from above the face material, a second heat insulating plate made of synthetic resin foam is integrated on the surface of the face material, Finishing material passes through the second heat insulating plate through the second heat insulating plate in a region where the first heat insulating plate, the face material and the second heat insulating plate overlap each other on the surface side of the second heat insulating plate. said face member and the second mounting pin screwed or implanted in the without Ri is intended to provide a construction method for heat insulating structure of the building, characterized in that to attach.

And in this invention, the 1st attachment pin for attaching a composite heat insulating board to a structural member penetrates the 1st heat insulating board from a face material, is screwed or driven into the structural member, and pierces from a face material to a structural member. Any length is enough. For this reason, a composite heat insulation board can be attached without using a special long attachment pin, and the rise in material cost by using a special long attachment pin can be suppressed. In addition, the first mounting pin for mounting the composite heat insulating plate does not exist at the position connecting the front and back of the second heat insulating plate, so the heat insulation is greatly reduced or the formation of a thermal bridge that causes condensation is prevented. Can do. Furthermore, the distance between the face material and the structural member is determined by the thickness of the first heat insulating plate, and the thickness of the first heat insulating plate is not so large even in the case of high heat insulation as described above. Easy to get status. For this reason, it is easy to stabilize the attachment state of the finishing material attached to the face material.

  When the density of the first heat insulating plate is made higher than the density of the second heat insulating plate, the mounting strength of the composite heat insulating plate can be improved.

  In the outer heat insulation in which the composite heat insulating plate is attached to the outer surface side of the structural member that is a constituent material of the wall of the building, the moisture permeability resistance of the face material is at least equal to or equal to the moisture permeability resistance of the first heat insulating plate. If it is less than that, it becomes easy to prevent internal dew condensation due to the dampness of the room being blocked by the face material in winter.

  Hereinafter, the present invention will be further described with reference to the drawings. In the drawings described below, the same reference numerals denote the same components.

  As shown in FIG. 1, a first heat insulating plate 2, a face material 3, a second heat insulating plate 4, and a finishing material 5 are provided on a structural member 1 of a building in order from the structural member 1 side. The present invention is applied to a building wall or ceiling, and the structural member 1 is a constituent member of a building wall or a constituent member of a building ceiling. More specifically, the present invention is applied to a wall or a ceiling of a building having an RC structure, a steel structure, a reinforced concrete structure, or a wooden frame structure. An RC wall or the like for a building with a structure, an ALC panel or the like for a building with a steel structure, a wall slab for a reinforced concrete building, or a column or a stud for a wooden frame structure. In addition, as the structural member 1 which is a constituent material of the ceiling part, an RC ceiling or the like is used for an RC structure building, an ALC panel or deck plate is used for a steel structure building, a ceiling slab or a wooden structure is used for a reinforced concrete building. In the case of a building with a frame structure, it is possible to list a field edge attached to a suspended tree.

  The first heat insulating plate 2, the face material 3, and the second heat insulating plate 4 constitute an integrated composite heat insulating plate 6. This integration can usually be performed by bonding with an adhesive.

  The first heat insulating plate 2 and the second heat insulating plate 4 are made of synthetic resin foam, and usually the same type of synthetic resin foam is used, but different types of synthetic resin foam can also be used. As a synthetic resin foam which comprises the 1st heat insulation board 2 and the 2nd heat insulation board 4, foams, such as a polystyrene, a polyurethane, polyethylene, a polyvinyl chloride, a phenol resin, can be used, for example. Among these, since it is excellent in compressive strength, water resistance, and heat insulation, it is preferable to comprise a polystyrene extruded foam plate.

  The face material 3 may be a plate material capable of obtaining the holding force of the second mounting pin 7b described later, and for example, a structural plywood, a fiber board, a synthetic resin plate, a metal plate, or the like can be used.

  The composite heat insulating plate 6 is attached to the structural member 1 by first mounting pins 7 a that are screwed or driven into the structural member 1 through the first heat insulating plate 2 from above the face material 3. The example shown in FIG. 1 uses a composite heat insulating plate 6 in which a first heat insulating plate 2, a face material 3 and a second heat insulating plate 4 are integrated in advance, and the first mounting pin 7a in this example is screwed. Alternatively, the driving is performed through the insertion hole 9 formed in the second heat insulating plate 4 before the finishing material 5 is mounted, or the head of the first mounting pin 7 a is attached to the face material 3 from the second heat insulating plate 4. It is performed while pushing down until it reaches the contact position. The insertion hole 9 and the insertion hole 10 formed when the head of the attachment pin 7a is pushed to the position of the face material 3 may be filled with the hole filling material 8 after the first attachment pin 7a is screwed or driven. preferable. As the hole filling material 8, in-situ foamed urethane, caulking material, or the like can be used.

  When the structural member 1 is a constituent material of a wall of a building, the finishing material 5 is an exterior material when the composite heat insulating plate 6 is external heat insulating attached to the outdoor side of the structural member 1, and the composite heat insulating plate 6 is an interior material in the case of internal heat insulation attached to the indoor side of the structural member 1. Moreover, when the structural member 1 is a constituent material of the ceiling part of a building, it is a ceiling material.

  The finishing material 5 is attached to the surface side of the second heat insulating plate 4 by a second mounting pin 7 b screwed or driven into the face material 3 of the composite heat insulating plate 6. The second mounting pin 7b has a length that does not penetrate at least the first heat insulating plate 2, and preferably has a length that allows the amount of biting into the first heat insulating plate 2 to be ½ or less of the thickness of the first heat insulating plate 2. is there.

  As the first and second mounting pins 7a and 7b, for example, screws, anchor bolts, nails or the like are used. Which one is used as the first and second mounting pins 7 a and 7 b is selected according to the material of the structural member 1 and the material of the face material 3.

  The thickness and density of the first heat insulating plate 2 and the second heat insulating plate 4 are preferably the same in order to reduce the types of constituent materials of the composite heat insulating plate 6 and facilitate manufacture and management, but are different. It can also be. For example, by making the first heat insulating plate 2 thicker than the second heat insulating plate 4, a margin can be given to the amount of biting of the second mounting pin 7b into the first heat insulating plate 2. On the contrary, by making the first heat insulating plate 2 thinner than the second heat insulating plate 4, the interval between the structural member 1 and the face material 3 is narrowed, and the mounting state of the composite heat insulating plate 6 by the first mounting pins 7a is easily stabilized. You can also. Further, by increasing the density of the synthetic resin foam constituting the first heat insulating plate 2 higher than the density of the synthetic resin foam constituting the second heat insulating plate 4, it is possible to increase the compression resistance of the first heat insulating plate 2. The mounting stability of the composite heat insulating plate 6 using the first mounting pins 7a can be easily improved.

  It is preferable that the moisture permeability resistance of the face material 3 is equal to or less than the moisture permeability resistance of the first heat insulating plate 2 and the second heat insulating plate 4 so as not to block moisture. In particular, in the outer heat insulation in which the composite heat insulating plate 6 is attached to the outer surface side of the structural member 1 constituting the wall portion of the building, moisture that has entered the composite heat insulating plate 6 from the indoor side is blocked by the face material 3 in the winter and is condensed. In order to prevent this, it is preferable that the moisture permeability resistance of the face material 3 is at least equal to or less than the moisture permeability resistance of the first heat insulating plate 4.

  Next, an example of the construction method of the heat insulation structure according to the present invention will be described.

  In this example, as shown in FIG. 2, a composite heat insulating plate 6 in which a first heat insulating plate 2, a face material 3, and a second heat insulating plate 4 are integrated in advance is used. The composite heat insulating plate 6 is attached to the structural heat insulating plate 6 with the first heat insulating plate 2 side facing the structural member 1 of the building and the first mounting pin 7a from above the face material 3. It is performed by screwing or driving into the structural member 1. The first mounting pin 7a is screwed or driven into the structural member 1 from above the face material 3 by, for example, forming the insertion hole 9 penetrating the second heat insulating plate 4 in advance corresponding to the screwing or driving position of the first mounting pin. In addition, the first attachment pin 7 a can be inserted into the insertion hole 9 and can be performed through the insertion hole 9. Further, without forming the insertion hole 9, it can be performed while pushing from the second heat insulating plate 4 until the head of the first mounting pin 7 a comes into contact with the face material 3. By this pushing, a pushing hole 10 is formed in the second heat insulating plate 4. In FIG. 2, the insertion hole 9 and the push-in hole 10 are shown together. However, this is for convenience of explanation, and it means that the formation of the insert hole 9 and the push-in must be used together. It is not a thing.

  Next, as shown in FIG. 3, the hole 9 or the push-in hole 10 is filled with the hole filling material 8 to prevent the occurrence of a location where the heat insulating property is lowered. In particular, in the case of the insertion hole 9, in order to facilitate the insertion of the first mounting pin, it is better to work with a hole having a diameter larger than the head diameter of the first insertion pin 7a. In this case, since the influence on the heat insulating property is likely to increase, it is preferable to fill the hole filling material 8. In the case of the push-in hole 10, if the head diameter of the first insertion pin 7a is small, the filling of the hole filling material 8 can be omitted. However, it is preferable to fill the hole filling material 8 when the head diameter of the first insertion pin 7a is large.

  After the screwing or driving of the first mounting pin 7a and the filling operation of the hole filling material 8 performed as necessary, the finishing material 5 is attached as shown in FIG. The finishing material 5 is attached by, for example, directing the finishing material 5 to the surface side of the second heat insulating plate 4 of the composite heat insulating plate 6 and screwing or driving a mounting pin 7b from the top of the finishing material 5 to the face material 3. It can be carried out.

  Furthermore, the other example of the construction method of the heat insulation structure concerning this invention is demonstrated.

  In this example, as shown in FIG. 5, a pre-product 11 in which only the first heat insulating plate 2 and the face material 3 are integrated is used. First, the first heat insulating plate 2 side of the pre-product 11 is directed to the structural member 1 with the building's structural member 1 side, and the first mounting pin 7a is screwed or driven into the structural member 1 from above the face material 3 11 is attached to the structural member 1.

  Next, as shown in FIG. 6, the second heat insulating plate 4 is integrated with the surface of the face material 3 of the pre-product 11 to constitute a composite heat insulating plate 6. The integration of the second heat insulating plate 4 can be performed by adhesion. In this example, the composite heat insulating plate 6 is configured by integrating the second heat insulating plate 4 at the site, and as a result, the composite heat insulating plate 6 is attached to the structural member 1 by the first mounting pins 7a. Further, in the case of this example, since the face material 3 is exposed when the first mounting pin 7a is screwed or driven, the second heat insulating plate 4 (see FIG. 6) is combined without the mounting hole 9 and the pushing hole 10. The heat insulating plate 6 can be configured.

  After the integration of the second heat insulating plate 4, the heat insulating structure according to the present invention can be constructed by attaching the finishing material 5 in the same manner as in FIG.
