Description

  The present invention relates to a heat insulating panel laying method in which a plurality of heat insulating panels are adjacent to each other in the longitudinal direction and laid on a roof.

  Long plate-like heat insulation panels are widely used as exterior wall materials and roofing materials for buildings. As a heat insulation panel, for example, a structure in which a rigid polyurethane foam is sandwiched between an upper surface material and a lower surface material formed of a paper material such as kraft paper or a steel plate is known. Such a heat insulating panel is manufactured by forming a belt-shaped heat insulating panel and then cutting it into a desired length. (See Patent Documents 1 and 2 below).

  By the way, there was a request to use a heat insulation panel as a roofing material of a large building for a long time, but the length of the heat insulation panel is limited due to the production line, and the conventional heat insulation panel is not long enough. Could not handle the roof of large buildings. In addition, if the heat insulation panel is made too long, there is a problem that it is difficult to carry it by a truck or the like.

  For this reason, it has been considered to construct a large building roof by laying a plurality of heat insulating panels adjacent to each other in the longitudinal direction on the roof. However, if a plurality of heat insulating panels are directly butted and connected and laid on the roof, there is a risk that water will leak from the connected portion and a problem may occur.

  The present invention has been made paying attention to such problems, and its purpose is to provide heat insulation adjacent to each other when a plurality of long plate-like heat insulation panels are adjacent to each other in the long direction and laid on the roof. It is an object of the present invention to provide a heat insulating panel laying method capable of preventing the occurrence of water leakage at the connection portion of the panel.

The above object can be achieved by the present invention as described below.
That is, the heat insulating panel laying method of the present invention is a heat insulating panel in which a plurality of heat insulating panels having a long plate-shaped heat insulating material and a face material covering the surface of the heat insulating material are laid on the roof in the longitudinal direction. Laying method,
Laying the first heat insulation panel so that the longitudinal direction is directed to the inclination direction of the roof;
An extension portion in which the heat insulating material of the second heat insulating panel is removed by a predetermined length from one end side in the longitudinal direction toward the other end side, and one end side in the long direction of the face material extends from the edge of the heat insulating material. Forming a step;
Compressing the interference part of the first heat insulation panel that interferes with the extension part when the extension part of the second heat insulation panel overlaps the first heat insulation panel;
And a step of laying the second heat insulating panel on the upper side in the inclined direction from the first heat insulating panel so that the extending portion of the second heat insulating panel is overlapped with the first heat insulating panel.

  According to this configuration, the second heat insulation panel is laid such that the extending portion of the face material formed by partially removing the heat insulation material of the second heat insulation panel overlaps the first heat insulation panel. can do. At this time, since the second heat insulation panel is laid on the upper side in the inclination direction from the first heat insulation panel, a connection portion between the first heat insulation panel and the second heat insulation panel, more specifically, the first heat insulation panel. The connection part of the heat insulating material of a panel and the heat insulating material of a 2nd heat insulating panel will be covered with the extension part of the face material of a 2nd heat insulating panel. Therefore, when a plurality of long plate-like heat insulation panels are adjacent to each other in the long direction and laid on the roof, it is possible to prevent water leakage from occurring at the connection portion between the adjacent heat insulation panels.

  In the heat insulating panel laying method of the present invention, the face material rises in a vertical direction from at least two corrugated portions formed along the width direction and opposite end portions of adjacent corrugated portions, or from each other. A pair of rising portions that rise while inclining in the approaching direction, and a pair of enlarged portions that extend in directions away from the tips of the rising portions, and in the region where the extending portions overlap, It is preferable to compress the pair of enlarged portions so that the interval is narrower than the interval between the pair of rising portions.

  When the face material includes a pair of rising portions and a pair of enlarged portions, when the extending portion of the second heat insulating panel is overlapped with the face material of the first heat insulating panel, the enlarged portion of the first heat insulating panel is the second. Interferes with the rising part of the insulation panel. Therefore, in the region where the extending portions of the second heat insulating panel overlap, the first heat insulating panel is compressed by compressing the pair of enlarged portions so that the distance between the pair of enlarged portions is narrower than the distance between the pair of rising portions. Will not interfere with the rising part of the second heat insulation panel. Thereby, the clearance gap between the face material of a 1st heat insulation panel and the face material of a 2nd heat insulation panel can be eliminated, and generation | occurrence | production of water leakage can be prevented effectively.

  In the heat insulation panel laying method of the present invention, it is preferable to peel off the corrugated shape portion connected to the rising portion and the heat insulating material bonded to the corrugated shape portion before compressing the pair of enlarged portions. .

  When compressing the pair of enlarged portions, the heat insulating material sandwiched between the pair of enlarged portions is also compressed, and force is also applied to the heat insulating material in the vicinity thereof, which may cause a problem that the face material swells or cracks. . Before compressing the pair of enlarged parts, the force when compressing the enlarged part is applied to the face material by peeling the corrugated part connected to the rising part and the heat insulating material bonded to the corrugated part. Since it is not directly applied, it is possible to prevent a problem that the face material swells or cracks.
