Summary of the Invention

Problems to be Solved by the Invention

[0004] The heat insulating panel disclosed in Patent Document 1 has a drainage groove formed on the vertical surface of a ventilation layer protrusion erected to form a ventilation layer. By adopting such a configuration, the drainage of moisture in the heat insulating panel is improved, but the drainage groove formed on the ventilation layer protrusion becomes an undercut portion. Therefore, there are problems such as the structure of the mold used in manufacturing becoming complicated and the manufacturing cost increasing.

Means for Solving the Problems

[0005] Therefore, the present invention is for solving the above problems, and its object is as follows. That is, in a heat insulating panel having a convex portion for forming a ventilation layer and a drainage groove, to simplify the mold used in manufacturing by forming the drainage groove so as not to become an undercut portion, and to provide a heat insulating panel that can be manufactured at a low cost.

[0006] In order to solve the above problems, the inventor conducted diligent research and arrived at the following configuration. That is, the present invention relates to one main surface of a plate-like body formed from a synthetic resin foam. The front Multiple protrusions are erected at required intervals, and at least one groove is formed on the tip surface of each protrusion in the direction of protrusion. Furthermore, on the other main surface, the back, multiple grooves are formed to improve adhesion with the substrate material. When viewed from the front, an insertable tongue is formed that protrudes outward from either one of the vertical directions and either one of the width directions of the outer periphery, and a tongue entry portion is formed on the other of the vertical directions and the other of the width directions of the outer periphery into which the insertable tongue of the adjacent insulation panel enters. This is an insulating panel characterized by the following features.

[0007] As a result, in an insulating panel having a convex portion that forms a ventilation layer and a groove for drainage, the recessed portion for drainage does not become an undercut, thus simplifying the mold used in manufacturing the insulating panel and enabling the provision of an insulating panel that can be manufactured at a low cost. In addition, since the recessed portion improves both drainage and ventilation, the performance of the insulating panel can be maintained over a long period of time.

[0008] Furthermore, the groove is Vertical direction It is preferable that it extends to the Vertical direction In this case, it is more preferable that each of the grooves in each of the adjacent protrusions is arranged on the same straight line.

[0009] These features improve drainage performance when the grooves are used as drainage channels. [Effects of the Invention]

[0010] According to the present invention, in an insulating panel having a convex portion that forms a ventilation layer and a groove for drainage, the mold used in manufacturing can be simplified by forming the groove for drainage so that it does not become an undercut, thereby providing an insulating panel that can be manufactured at low cost. Furthermore, since the groove improves both drainage and ventilation, the performance of the insulating panel can be maintained over a long period of time. [Brief explanation of the drawing]

[Figure 8] This is an explanatory plan view showing an example of the installation of an insulating panel in another embodiment. [Modes for carrying out the invention]

[0012] In this embodiment, the insulation panel 100 will be described with the front surface 10 being the surface facing the wall surface W (see Figure 8), which is the mounting surface to the building. As shown in Figures 1 to 6, the insulation panel 100 in this embodiment is formed into a rectangular plate-like body when viewed from the front. A synthetic resin foam, such as expanded polystyrene foam, is preferably used as the material for the insulation panel 100. In this embodiment, the insulation panel 100 has insertable tongue pieces 12 that protrude outward from the outer peripheral edges 100C and 100D of the front surface 10, which is one of the main surfaces. In addition, a plurality of roughly rhombic columnar protrusions 14 are erected in a row on the front surface 10. A zigzag gap 15 is formed on the front surface 10 by the multiple protrusions 14 erected at various locations on the front surface 10. If the insulation panel 100 is formed into a front-view shape with a width of 910 mm and a height of 1200 mm, the ease of installation in Japanese architectural styles can be improved.

[0013] The gap 15 is formed to open at the outer edges 100A, 100B, 100C, and 100D of the insulation panel 100. In addition, a plurality of grooves 17 are formed on the tip surface 16 of the protruding portion 14. The grooves 17 are symmetrical with respect to the diagonal in the vertical direction of the rhombus on the tip surface 16 and extend parallel to the height direction of the insulation panel 100. The width and depth dimensions of the grooves 17 are not particularly limited, but it is preferable that they are formed to be of a size and shape that does not obstruct the flow of water due to surface tension when the mounting surface (wall surface W) to the building and the tip surface 16 are in close contact. Both ends of the grooves 17 in the longitudinal direction are formed to open into the gap 15. Furthermore, the grooves 17 formed on adjacent protrusions 14 in the height direction of the insulation panel 100 are all positioned on the same straight line extending in the height direction of the insulation panel 100.

[0014] Furthermore, on the other main surface, the back surface 20, a grid pattern is formed by multiple grooves 21 arranged at required intervals in the height and width directions (vertical and horizontal directions in Figure 2) of the insulation panel 100. The spacing of the grooves 21 in the height and width directions of the insulation panel 100 can be adjusted as appropriate. These grooves 21 forming a grid pattern improve adhesion with the base material superimposed on the back surface 20, thereby increasing the strength of the wall that is formed later. In addition, the back surface 20 has tongue-shaped entry portions 22 that are recessed inward from the outer peripheral edges 100A and 100B facing the insertable tongue-shaped piece 12. The insertable tongue-shaped piece 12 and the tongue-shaped entry portions 22 are formed to be half the thickness of the insulation panel 100. The amount of protrusion of the insertable tongue-shaped piece 12 and the amount of recess of the tongue-shaped entry portions 22 are formed to be equal.

[0015] The heat insulation panel 100 formed as described above is attached to the wall surface W of the building as shown in FIG. 7. Note that FIG. 7 shows a state where the heat insulation panel 100 (the wall surface W of the building) is facing from the outdoor side of the building. When the operator arranges the heat insulation panel 100 in the horizontal direction with respect to the wall surface W of the building, the tongue piece insertion part 22 of the outer peripheral edge 100D of the newly arranged heat insulation panel 100 is inserted into the insertion tongue piece 12 of the outer peripheral edge 100B of the previously arranged heat insulation panel 100 in the direction of arrow A in FIG. 7 for arrangement. Also, when the operator arranges the heat insulation panel 100 in the height direction, as shown by arrow B in FIG. 7, the tongue piece insertion part 22 of the outer peripheral edge 100C of the newly arranged heat insulation panel 100 may be inserted into the insertion tongue piece 12 of the outer peripheral edge 100A of the previously arranged heat insulation panel 100 for arrangement.

[0016] The heat insulation panels 100 arranged in this way can connect adjacent heat insulation panels 相互の凸部14、隙間15および凹溝17を連続させた状態で連結することができる。特に凹溝17においては、いずれも建物の壁面Wにおいて高さ方向の全範囲において同一直線上(同一鉛直線上)に配設されているため、最短距離で排水を行うことができ好都合である。

[0017] Also, between the wall surface W of the building and the front surface 10 of the heat insulation panel 100, a small passage formed by the concave groove 17 which is a straight groove and a large passage (ventilation part (also serving as a drainage part)) formed by the zigzag-shaped gap 15 are formed. Since both ends of the small passage formed by the concave groove 17 communicate with the large passage formed by the gap 15, it is possible to draw out (promote the circulation of) the air and moisture in the concave groove 17 which is a small passage by the flow of air and moisture flowing through the gap 15 which is a large passage. Thereby, the initial performance of the heat insulation panel 100 can be maintained over a long period.

[0018] It should be noted that there seems to be some incorrect or unclear expressions in the original text, especially in the part of "相互の凸部14、隙間15および凹溝17を連続させた状態で連結することができる" in the translation of , which is translated as "相互の凸部相互の凸部14、隙間15および凹溝17を連続させた状態で連結することができる" in the current translation, and the correct meaning needs to be further determined according to the context. You can check and correct it if necessary.In addition, the small passage formed by the concave groove 17 has a very small flow path cross-sectional area, about 1 / 20 of that of the large passage. Therefore, the loss of the foamed resin of the heat insulation panel 100 can be minimized, and sufficient heat insulation performance applicable even in cold regions can be maintained. Further, since a plurality of gaps 15 and concave grooves 17 having different sizes are formed on the surface (front surface 10) facing the wall surface W of the building, an improvement in sound insulation performance can also be expected. In improving the sound insulation performance, it is preferable to arrange a plurality of concave grooves 17 having at least one of the width dimension and the depth dimension different on the tip surface 16 of the convex portion 14.

[0019] As described above, the heat insulation panel 100 according to the present invention has been described based on the embodiments. However, the technical scope of the present invention is not limited to the above embodiments. For example, in the above embodiments, a form in which the heat insulation panel 100 is arranged so as to cover the wall surface W of the building is illustrated. However, a form in which the heat insulation panel 100 is attached to the vertical surface of the foundation can also be adopted.

[0020] Also, in the present embodiment, a form in which the heat insulation panel 100 is directly attached to the wall surface W of the building is illustrated. However, the usage form of the heat insulation panel 100 according to the present invention is not limited to this form. For example, as shown in FIG. 8, after attaching a rectangular parallelepiped heat insulation panel 200 having a thickness of t2 formed in a simple plate shape to the wall surface W of the building, the front surface 10 of the heat insulation panel 100 having a thickness of t1 is opposed to the outdoor side surface of the rectangular parallelepiped heat insulation panel 200. It is also possible to adopt a form of attachment in this state. According to such a form, while securing the heat insulation material thickness T required for a long-term excellent house, a large passage due to the gap and a small passage due to the concave groove 17 can be formed within the range of the heat insulation material thickness T. <( [[ID=]]

[0021] Also, in the present embodiment, a form in which the convex portion 14 is formed in a rhombic column shape is illustrated. However, the convex portion 14 can adopt forms such as a columnar body or a frustum of a cone. In short, the three-dimensional shape of the convex portion 14 is not particularly limited as long as the tip surface 16 is parallel to the attachment surface of the building.

[0022] Furthermore, in this embodiment, the groove 17 formed on the tip surface 16 in the protruding direction of the protrusion 14 is exemplified as extending vertically when the heat insulating panel 100 is installed, but the embodiment is not limited to this form. The groove 17 can also extend in a direction inclined at a required angle with respect to the vertical direction within the plane of the tip surface 16. Also, the number of grooves 17 arranged on the tip surface 16 is not limited to three.

[0023] Furthermore, while this embodiment illustrates a configuration in which a grid pattern is formed by arranging grooves 21 on the back surface 20, the embodiment is not limited to this configuration. The grid pattern can also be formed by protruding pieces on the back surface 20. Moreover, a configuration in which the back surface 20 is a flat surface can also be adopted.

[0024] Furthermore, in this embodiment, when adding insulation panels 100 in the horizontal direction, the additional insulation panels 100 are installed from the direction of arrow A (horizontal direction) in Figure 7, but it is also possible to add insulation panels 100 from the vertical direction. Similarly, when adding insulation panels 100 in the vertical direction, the additional insulation panels 100 are installed from the direction of arrow B (vertical direction) in Figure 7, but it is also possible to add insulation panels 100 from the horizontal direction.

[0025] In addition to the modifications described above, it is also possible to adopt forms that appropriately combine the modifications described in the embodiments. [Explanation of symbols]
