Description

Description: TECHNICAL FIELD The present invention relates to imparting heat insulation to a wall of a building or a structure, and in particular, to imparting heat insulation to a wall to a wall surface. The present invention relates to a heat insulating panel provided, a heat insulating wall provided with the heat insulating panel, and a method for constructing the heat insulating wall.

[Related Art] Conventionally, as a heat insulating panel attached to a building or a wall of a building to provide heat insulating property, an inorganic material such as pulp mixed cement or alkali glass fiber reinforced cement is provided on one surface of a synthetic resin foam plate. The thing provided with the surface material is known. A heat insulating wall using this heat insulating panel is configured by arranging heat insulating panels on a wall surface and fixing the heat insulating panels with anchor bolts driven into the wall surface.

By the way, the inorganic surface material of the heat insulating panel must be thick in order to obtain the required impact resistance, the extreme part compressive resistance, and the like, and if this is used as a large heat insulating panel, it becomes heavy and difficult to handle. However, the insulation panel is relatively small. Therefore, when installing the heat insulating wall using this heat insulating panel, the number of attached heat insulating panels increases and the workability is poor, and the joint between the heat insulating panels also increases, so that the high heat insulating property required for a freezing warehouse or the like is obtained. There is a difficult problem.

On the other hand, a heat insulation panel in which a metal plate is attached to one surface of an inorganic foam plate such as an isocyanurate foam is known. The heat insulating wall using this heat insulating panel is configured by arranging and fixing the heat insulating panel on the body edge previously fixed to the wall surface, with the surface provided with the metal plate as the front side.

By the way, in order to obtain the required strength of the inorganic foam board, not only is it difficult for a large-sized heat insulating panel to be used, but also to fix the body edge to the wall before attaching the heat insulating panel. It is a heavy burden.

Therefore, it is conceivable that a large-sized heat insulating panel is constituted by a synthetic resin foam plate and a metal plate, and this is directly attached to a wall surface using anchor bolts.

[Problems to be Solved by the Invention] However, there are the following problems in directly attaching a heat insulating panel using a synthetic resin foam plate to a wall surface with anchor bolts.

(1) In order to attach a heat insulating panel with an anchor bolt, a through hole is provided in the heat insulating panel, and an anchor bolt is passed therethrough. However, the through hole causes a decrease in heat insulation. Therefore, if the number of through holes is large, even if the heat insulation panel is enlarged to reduce the number of joints, the heat insulation cannot be improved as a whole.

(2) As described above, there is a limit to the through hole through which the anchor bolt passes, but, naturally, the heat insulating panel needs to be firmly fixed to the wall surface.

(3) Since a synthetic resin foam plate generally has a larger thermal expansion coefficient than a metal plate, a heat insulating plate provided with a metal plate on one surface thereof is likely to be warped. If the four circumferences are firmly fixed to the wall surface, warpage can be prevented, but for that purpose, the number of through holes must be increased, which causes a decrease in heat insulation.

[Means for Solving the Problems] Means taken to solve the problems will be described with reference to the drawings. The invention of claim 1 is a panel perspective view of FIG. 1, FIG. As shown in a sectional view showing a state of attachment to a wall surface in FIG. 8, a heat insulating panel 4 for a wall, in which metal plates 2 are attached to both surfaces of a synthetic resin foam plate 1,

Examples of the synthetic resin foam plate 1 include polystyrene, polyurethane, polyvinyl chloride, phenolic resin, or a synthetic resin added with an inorganic filler and foamed. Foaming may be used. Most preferably, it is an extruded expanded polystyrene plate such as Stylofom (trade name).

Examples of the metal plate 2 include a zinc iron plate, a copper plate, a stainless steel plate, and an aluminum plate. It is preferable that at least the metal plate 2 on the front side after the urging is coated in advance.

The overlapping margin 3 may be formed so as to protrude over one entire side of the synthetic resin foam plate 1 or may be formed so as to protrude from a part of the one side.

The heat insulation panel 4 may be formed in a square shape or the like, or may be formed in a rectangular shape with the overlap margin 3 provided on the long side, but as in the invention of claim 2, the heat insulation panel 4 has a rectangular shape and is formed on the long side. It is preferable from the viewpoint of strength that the long-side end portion of the metal plate 2 on both sides has a bent portion 5 which is bent along the long-side side end surface. See figure).

In the invention of claim 4, the reason why the anchor bolt 12 is passed through the place where the overlap allowance 3 is overlapped is that one anchor bolt 12 can be used for fixing two heat insulating panels. Further, the stud 10 functions to press a wide area along the side of the heat insulating panel 4.

The metal plate 2 serves to support the anchor bolt 12 at the same time.

The hiring spring 6 according to the invention of claim 8 functions to connect the arranged heat insulating panels 4 up and down. The attachment 9 assists the fixing in the long side direction in which the fixing interval by the anchor bolt 12 is widened, and also functions to prevent the fitting of the hiring spring 6 from coming off due to warpage or the like.
