DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel for forming an external heat insulating layer on buildings and structures.

[0002]

2. Description of the Related Art Conventionally, a heat insulating panel for forming a heat insulating base having heat insulating properties and airtightness has been disclosed in Japanese Patent Application Laid-Open No. 6-294172. The main component members are a load-bearing wall surface member having a nailing portion fixed around and having a nailing portion abutting on the outdoor side surface of the frame, and a heat insulating member provided on the indoor side surface surrounded by a frame member of this surface member. There was something to do.

[0003]

In the panel having the structure described above, the frame member is formed smaller than the frame assembly for convenience of inserting the panel body between the frame assemblies. It is described that a gap is generated, and it is described that the gap is filled with a heat insulating packing arranged along the indoor side outer peripheral surface of the frame member, but the gap between the frame member and the frame crushes the heat insulating packing. If the thickness is smaller than the thickness in the state, the heat-insulating packing will be rubbed off when the panel body is attached, and if it is wider than the thickness restored by the self-elasticity of the heat-insulating packing, the frame member and the shaft It was not possible to fill the space between the pairs, and all of them resulted in a decrease in heat insulation and airtightness and the occurrence of dew condensation near the site.

Further, the surface member for the load-bearing wall is easily affected by a change in the temperature of the outside only through the outer wall material, or only through the outer wall material and the air layer, between the outside and the outside. In addition, there is a concern that dew condensation may occur at the boundary between the load-bearing wall surface member and the heat insulating member. Further, the portion where the frame member is in contact with the load-bearing wall surface member and the frame member easily become a thermal bridge, and there is room for improvement in heat insulation performance.

Furthermore, not only is it difficult to cut because of having the frame member, but also it is necessary to scrape off a heat insulating member of a predetermined width on the side of the cut face material for the purpose of nailing to provide a nailing portion. Since it is extremely difficult to adjust the dimensions at the construction site when disposing the heat insulating panel near the opening or the like, it has been necessary to form the panel to a predetermined size at the time of panel production.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention solves the above-mentioned drawbacks by using a nail material having a substantially rectangular face material and a predetermined width along at least two opposite edges on the surface of the face material. A heat insulating layer arranged in a range excluding the portion, and a sub heat insulating portion which is placed so as to be in contact with the side surface of the heat insulating layer on the surface of one nailing portion and protrudes to the side of the nailing portion over a predetermined width. Having a heat insulating layer and a sheet material smoothly straddling the surface of the sub heat insulating portion, the sub heat insulating portion is rotatable around the boundary between the heat insulating layer of the sheet material and the sub heat insulating portion, and the heat insulating layer is Insulation that is divided into a plurality of blocks by cutting lines along the longitudinal direction and width direction, each block adheres to the sheet material on its surface, and is attached to the surface of the face material by an adhesive arranged in a small area Suggest a panel.

Further, in this heat insulation panel, a first step portion whose surface side protrudes is formed on a side surface of the sub heat insulation portion, and a side surface of the heat insulation layer adjacent to the nailing portion on which the sub heat insulation portion is not provided. Can form a second step portion in which the front surface side is cut off.

The nailing is performed while exposing the nailing portion by moving the nailing portion, and after the nailing is completed, the nailing portion can be covered with the sub heat insulating portion, and the construction is easy. By engaging the first step portion and the second step portion, it is possible to form an ideal external heat insulating structure having no heat insulating defect. In the range of the width of the first step portion and the width of the second step portion, an error in the interval between the adjacent heat insulating panels can be absorbed, and the external heat insulating structure can be reliably formed. The heat-insulating layer is divided into a plurality of blocks by cutting lines along the longitudinal and width directions, and each block is adhered to the sheet material on its surface, and attached to the surface of the face material by an adhesive arranged in a minute area. Therefore, even if dimensional adjustment is required by cutting the heat insulation panel during construction, each block adjacent to the cut surface should be a sub heat insulation part that can rotate around the sheet material on the cutting line as an axis. Even if you need to adjust the dimensions at the construction site,
The nailing is performed while exposing the nailing part, and after the nailing is completed, the nailing part can be covered with the sub-insulation part, so that the outer heat-insulating layer without the insulation defect part can be easily formed even in the vicinity of the opening or the like. can do.
