[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel mounting structure for fixing a heat insulating panel and a rim to a frame member made of a metal material. The present invention relates to a mounting structure for the heat insulating panel, which can efficiently prevent the occurrence of dew condensation occurring at the tip of the provided stopper.

2. Description of the Related Art In a conventional residential building, a frame member made of wood or reinforced concrete is mainly used. As a method of attaching a heat insulating panel to such a wooden frame, an internal heat insulating method of arranging the heat insulating panel so as to be fitted between the frame and a frame, or an external heat insulating method of mounting the heat insulating panel to the frame from the outside side is used. Are known.

FIG. 3 is a sectional view showing a conventional heat insulating panel mounting structure using an external heat insulating method. The heat insulating panel 101 is temporarily attached to the pillar or stud 102 from the outdoor side β. In addition, the trunk 104 is formed from above the heat insulating panel 101.
Using a plurality of nails 103 (only one is shown in FIG. 3),
The nail 103 is nailed so that the tip of the nail 103 reaches the inside of the pillar or the stud 102. An exterior material 106 is mounted on the rim 104, and an interior material 107 is mounted on the indoor side α of the pillar or stud 102.

The mounting structure of the heat insulating panel by the external heat insulating method shown in FIG. 3 is different from the mounting structure of the heat insulating panel by the internal heat insulating method in that (1) the heat insulating panel 101 is mounted on the outdoor side β of the pillar or the stud 102. (2) Outdoor side β and indoor side α
Since there is no heat (hot or cold) conduction path between them, the heat insulation effect is high, and (3) the construction is easy.

On the other hand, in recent years, a mounting structure of a heat insulating panel using a frame (hereinafter referred to as a frame member) made of a lightweight aggregate made of metal is applied to a house building or the like. Has become. Unlike the reinforced concrete and wooden members shown in FIG. 3, this frame member has an advantage that resources can be effectively used because it can be recycled.

However, when this metal frame member is applied to a structure for mounting a heat insulating panel by the method shown in FIG. 3, the following inconveniences occur. That is,
In FIG. 4, similarly to FIG. 3, the heat insulating panel 101 is temporarily attached to the frame member (indicated by reference numeral 108 in FIG. 4), and then the body edge 104 is fixed to the stopper 105 from above the heat insulating panel 101 (FIG. 4).
In this case, a nail is used, but a screw may be used). This stopper is driven into the frame member 108, and the distal end side is exposed in the internal space E of the frame member 108. The temperature of the exterior material 106 is the temperature on the outdoor side β, and the temperature of the space γ between the heat insulating panel 101 and the interior material 107 is close to room temperature. Therefore, especially in winter, the space γ and the stopper 1
05, the temperature difference from the tip is large, and as a result, dew condensation occurs on the tip side of the stopper 105 (portion exposed to the relatively high temperature space γ).

[0007] When the difference between the temperature of the outdoor side β and the temperature of the indoor side α is large (for example, during heating in winter), this dew condensation occurs constantly because the indoor side α is in a high humidity. The moisture caused by the dew condensation causes the frame member 108 to gradually corrode. Such corrosion not only renders the framing member 108 unrecyclable, but can also damage (i.e., reduce structural strength) the framing member 108 if the erosion is severe.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for mounting a frame member made of a metal material when the heat insulating panel and the rim are fastened to the frame member using nails and / or screws as fasteners. An object of the present invention is to prevent the occurrence of dew condensation occurring on the tip side of the fastener exposed to the internal space. Another object of the present invention is to prevent the dew condensation from occurring, thereby preventing corrosion of the frame member, thereby ensuring recycling of the frame member, and preventing damage to the frame member due to corrosion. Is to prevent it.

[0009]

SUMMARY OF THE INVENTION The inventor of the present invention concludes that the above-mentioned dew condensation is caused by the fact that the cold heat on the outdoor side is immediately transmitted to the stopper and the stopper is exposed to the space inside the wall or the inner space of the frame member. Is reduced to such an extent that condensation occurs,
Therefore, the present inventors have found that if a member having a large heat capacity for buffering the cold heat is provided in the cold heat transmission path, the dew condensation can be prevented, and the present invention has been accomplished.

That is, in the mounting structure of the heat insulating panel of the present invention, the heat insulating panel is disposed from the outdoor side on a frame member made of a metal material, and further, a long metal plate material and a body edge are provided on the outer surface of the heat insulating panel. It is arranged, these longitudinal metal plate material and the body edge are fastened to the frame member via the heat insulating panel, the longitudinal metal plate material, by a first fastener group,
The end of each stopper penetrates the heat insulation panel to reach the frame member, and is attached to the outer surface side of the heat insulation panel,
The body edge is attached to an outer surface side of the long metal plate by a second group of fasteners.

The mounting structure of the heat insulating panel of the present invention can be applied not only to ordinary houses but also to simple houses which are dismantled in a short period of time, and can be applied not only to walls but also to frame members for floors and roofs. Applicable.

As the frame member, a member having a cross section of C-shape, H-shape, U-shape, square or the like is used.
The material is not particularly limited as long as it is a metal, and various materials such as iron, stainless steel, aluminum, copper, and various alloys are used.
Further, those obtained by plating these are also used. The C
The opening in the shape of letter "H" or "U" is formed so as to be perpendicular to the surface on which the heat insulating panel is mounted. In addition,
An interior base material or an interior material is attached to a surface of the frame member facing the surface to which the heat insulating panel is attached. In addition,
For example, the two frame members having a C-shaped cross section are abutted so that the opening sides face each other, and the two frame members are constructed so that the contact surface is perpendicular to the front surface (or the back surface) of the heat insulating panel. Is done.

As the heat insulating panel, those which can be used in the conventional external heat insulating method, for example, rigid polyurethane foam,
Insulation of synthetic resin foam such as polystyrene foam, polyethylene foam, polypropylene foam, phenol foam, inorganic fiber insulation such as glass wool and rock wool, or organic fiber insulation such as cellulose fiber, or liner paper or kraft paper paper,
Synthetic resin films such as polyethylene films and polyester films, metal foils and vapor-deposited layers such as iron, aluminum and stainless steel, or laminates composed of any number of these layers, structural plywood, particles, hard boards, sheathing boards, plaster A heat insulating panel obtained by laminating the heat insulating material on a board, a hard wood chip cement board, a lath sheet or the like as a face material can be used.

As the longitudinal metal plate, a band plate made of a metal such as iron, stainless steel, aluminum, or copper or an alloy thereof is used.

As the stopper, for example, a screw and / or a nail is used. The thickness and the material of the stopper are appropriately selected according to the material, thickness, and the like of the metal constituting the frame member. As the material of the stopper, it is possible to use a material made of non-metal such as engineering plastic, FRP, and ceramic, in addition to metal such as iron and stainless steel. The screw can be a commonly used screw, the screw head may be round, pan, flat, cheese, further, hexagon, square, etc., any shape, such as a minus hole, plus hole, Hexagonal hole, square hole, ULR,
It suffices if processing such as LH is performed and it can be turned and screwed with a tool. Further, the shape of the screw tip may be any shape that is normally used, such as a cutting edge or a sharpened point. The screw portion may be any of a full screw and a half screw, and may be any of a single-start screw, a double-start screw, a high-low screw, and the like.

The heat insulating panel can be attached to the frame member by a third group of fasteners for fixing only the heat insulating panel. At this time, the ends of the stoppers reach the frame assembly member (through the thickness of the metal plate constituting the frame assembly member, so that the tip is exposed to the space in the wall or the internal space of the frame member). ) Can also be attached. Further, the heat insulating panel can be attached to the frame member by using an adhesive, a pressure-sensitive adhesive, or a double-sided pressure-sensitive adhesive tape, regardless of the group of the fasteners.

The longitudinal metal plate is attached to the outside of the heat insulating panel in a longitudinal direction or a lateral direction by a first stopper. When the heat insulating panel is attached by the third group of fasteners, the longitudinal metal plate is attached so as to cover the third group of fasteners. The second group of fasteners is used to attach the body edge to the longitudinal metal plate, but the tip of each of the fasteners that form the second group of fasteners does not reach the frame member. When attached, the long metal plate functions as a large heat capacity member for buffering the cold heat of the outside air conducted through the second group of fasteners and the first group of fasteners. In addition, the longitudinal metal plate member itself is integrally connected to the frame member by the first group of fasteners, and also functions to firmly fix the heat insulating panel to the frame member.

As described above, the body edge (may be a vertical body edge or a horizontal body edge) is attached to the long metal plate by the second group of fasteners. You may attach so that the front-end | tip of each stop which comprises the 2 stop group may reach a frame member. Also in this case, the long metal plate functions as a large heat capacity member for buffering the cold heat of the outside air conducted through the second group of fasteners. Metal material cannot be used for the rim, thermal conductivity is 0.5k
Wood, plastic materials and the like having a cal / mH ° C or lower are preferably used.

In the present invention, a heat insulating means can be used in order to prevent both ends of the longitudinal metal plate from being exposed. For example, the width of the body edge is larger than that of the long metal sheet material, and attached to the long metal sheet material so that both side edges protrude from both side edges of the long metal sheet material, separately from the long metal sheet material and the body edge. The created heat insulating member made of a synthetic resin or the like can be filled in the gap between the protruding portion of the body edge and the heat insulating panel. In this case, a band-shaped or thick string-shaped member having elasticity can be used as the heat insulating member. The filling of the heat insulating member made of a synthetic resin can be performed before the body edge is attached to the longitudinal metal plate, or can be performed after the body edge is attached to the longitudinal metal plate. The heat insulating member can be formed by coating or pouring a foaming stock solution such as a rigid polyurethane foam after attaching the rim to the longitudinal metal plate material. Further, a part of the body edge can be used as the heat insulating means. That is, it is possible to use, as heat insulation means, both side protrusions of the body edge having a concave shape such that the indoor side covers the long metal plate side.

[0020]

A typical example of the operation of the present invention will be described below. When the indoor temperature is high and the outdoor temperature is low, the indoor heat is transferred to the first fastener group (when the heat insulating panel is attached to the frame member by the third fastener group, the first and Third
) To the longitudinal metal plate material
Cold heat on the outdoor side is transmitted to the long metal plate material via the second group of fasteners. Further, since the heat insulating member insulates the side end surface of the longitudinal metal plate material, the flow of cold heat from the end surface to the heat insulating member or the heat flow of the heat insulating member from the end surface hardly occurs. .

The first and second metal plates are made of first and second metal plates.
(When the heat insulating panel is attached to the frame member by the third fastener group, the heat capacity is larger than that of the first fastener group). For this reason, the heat from the indoor side is transmitted to the first stopper group (when the heat insulating panel is attached to the frame member by the third stopper group, the first stopper group).
And the third stopper group) are stored in the longitudinal metal plate material. The heat stored in the longitudinal metal plate can be insulated by a heat insulating member made of an elastic synthetic resin material. On the other hand, the cold heat from the outdoor side is transmitted to the long metal plate material via the second group of fasteners. That is, since the metal long metal plate acts to buffer the cold transmitted from the outdoor side via the second stopper group by its heat capacity, the first stopper group (the heat insulating panel is the When the third and third stopper groups are attached to the frame member by the third stopper group, the temperatures at the distal ends of the first and third stopper groups do not become so low as to cause dew condensation.

In the present embodiment, the longitudinal metal plate 3 is a flat steel having a thickness of 4.5 mm, and has a width slightly smaller than the width of the frame member 1. To attach the longitudinal metal plate member 3, screws n1 (only two screws are shown in FIG. 1) constituting the first screw group N1 are used, and these screws are spaced apart in the longitudinal direction of the frame member. The screw is penetrated in two rows so as to pass through the thickness of the frame member 1 and expose the distal end side of each screw to the internal space E of the frame member 1. Note that, without using the screw n3, the heat insulating panel 2 was formed with an adhesive, a pressure-sensitive adhesive, a double-sided tape, or the like.
Can be attached to the frame member 1.

Next, heat-insulating packings 5 and 5 for covering the end surfaces of the both sides are attached to both sides of the long metal plate 3. In the present embodiment, the packing 5 is a band-shaped material slightly thicker than the thickness of the long metal plate 3. As the material of the packing 5, various rubbers such as chloroprene rubber and EPDM rubber, foamed or non-foamed plastics such as polyvinyl chloride and polyolefin, which have compression elasticity can be used. In this embodiment, an adhesive layer is formed on one surface of the heat insulating packing 5 in advance.
The heat insulating packing 5 is attached by pressing against the surface.

The width of the body edge 4 is wider than the width of the longitudinal metal plate material 3, and both side ends 41, 41 thereof are provided.
Are attached so as to protrude above the longitudinal metal plate material 3. A screw n2 (only one screw is shown in FIG. 1) constituting the second screw group N2 is used to attach the body edge 4, and each screw is spaced apart in the longitudinal direction of the shaft assembly member 1, The tip of the screw penetrates the longitudinal metal plate 3 and is hit so as to stop in the middle of the heat insulating panel 2. By screwing the body edge 4 to the longitudinal metal plate material 3, the heat insulating packing 5 is sandwiched between both side ends 41, 41 of the body edge 4 and the heat insulating panel 2, whereby the end of the longitudinal metal plate material 3 side is provided. Insulation is provided.

Hereinafter, the operation of this embodiment will be described with reference to FIG. In winter, when the temperature of the indoor side α is high and the temperature of the outdoor side β is low, the heat HE of the indoor side α is transmitted to the space γ between the interior material 7 and the heat insulating panel 1, and the heat HE of this space is , A screw n3 forming the third screw group N3 and a screw n1, n1 forming the first screw group N1,
It flows into the long metal plate 3.

On the other hand, the cold heat CE on the outdoor side β flows into the longitudinal metal plate 3 via the exterior material 6 and the screws n2 forming the second screw group N2. Since the side end surface of the long metal plate material 3 is insulated by the heat insulating packings 51, 51, almost no inflow of cold heat and no outflow of hot heat from the end surface occur.

The heat capacity of the longitudinal metal plate 3 is overwhelmingly larger than the total heat capacity of all the screws of the third screw group N3, the first screw group N1, and the second screw group N2. Therefore, the longitudinal metal plate member 3 is provided with the cold heat CE from the outdoor side β and the indoor side α
The longitudinal metal plate material 3 acts as a buffer member for the cold / hot CE so as to cancel the hot HC from the heat, and the temperature on the tip side of each screw constituting the third screw group N3 and the first screw group N1 is controlled. The difference between the temperature of the space γ between the interior material 7 and the heat insulating panel 1 (that is, the temperature of the internal space E of the frame member 1) is extremely small, and no dew condensation occurs. The indoor side α
Temperature and the temperature of the outdoor side β are both low,
Even if the temperature of the indoor side α suddenly rises, the temperature of the space γ between the interior material 7 and the heat insulating panel 1 does not suddenly rise. Therefore, also in this case, the third screw group N
3. Since the difference between the temperature of the tip of each screw constituting the first screw group N1 and the temperature of the space γ between the interior material 7 and the heat insulating panel 1 does not become large, dew condensation does not occur.
