[0002]
[Prior art]
In the case of replacing an existing roof such as a folded plate, there are many methods of stacking a new roof without removing the roof material constituting the existing roof.
For example, in Japanese Patent No. 2661616, a fixture is fixed to a peak portion of a roof in which peaks and bottoms are alternately continuous, and an upper structural material corresponding to a rafter is fixed to the fixture, and the upper portion is further fixed. A structure is described in which an upper support is fixed to a structural material to support an exterior material.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional repair structure, it is necessary to prepare a fixture according to the mountain shape of the existing roof.
In addition, since the above-described conventional technology is a structure in which a new roof is simply laid on the existing roof, the heat insulation performance largely depends on the existing roof, and the heat insulation may not be sufficient depending on the structure of the existing roof. .
Therefore, a heat insulating structure in which a heat insulating material made of foam is dropped into the valley is proposed, but existing roofs such as folded plates have a wide variety of widths, heights, hull shapes, etc., and the valleys of the existing roof It was necessary to prepare a heat insulating material molded according to the shape, which was extremely inefficient.
[0004]
[Means for Solving the Problems]

A plurality of members are arranged so as to cross the flow direction, and a heat insulating layer is polymerized in the left-right direction between the receiving members, thereby forming a heat insulating layer on the existing roof without gaps, The top surface of the heat insulating material is made substantially the same level, and a different heat insulating layer is interposed on the receiving member and the heat insulating material, and the exterior material holding member of the newly installed roof is fixed to the receiving member and the external material is held on the holding member. The present invention relates to a repair structure and a repair method characterized by laying a new roof .
In the repair method of the present invention, the step of arranging the receiving member and the heat insulating material will be described as the first step, and the step of arranging the holding member and the exterior material will be described as the second step.

In the first embodiment shown in FIG. 1 (FIG. 2 is an enlarged view of the main part), the receiving member 2 is disposed first, or the receiving member 2 and the heat insulating material 3 are alternately disposed in this order.
[0006]
The existing roof 1 refers to a roof in a vertical form such as a vertical flat wall, a tile rod, and a folded plate in which peaks and valleys are alternately formed, and may have any shape.
The existing roof 1 in the illustrated embodiment is a folded-plate roof, and supports the exterior material 13 on a tight frame 12 fixed to the upper surface of a base portion 11 made of a steel frame such as a beam, a purlin, a trunk edge, and the like. The side edge overlapping portions 131 and 131 of the exterior packaging materials 13 and 13 that are adjacent to each other at the top of the twelve peak portions 121 are fixed by the sword bolt 14, the pressing material 15, and the nut 16.

[0007]
The receiving member 2 indirectly supports the new roof, and specifically, the exterior material 4 constituting the new roof (hereinafter referred to as a new exterior material to distinguish from the exterior material 13 constituting the existing roof 1). ) Is fixed. If this receiving member 2 can be fixed to the mountain portion 17 of the existing roof 1 and has a strength capable of indirectly supporting the new roof as described above, its shape configuration and material configuration are limited. Rather, for example, the cross-section may be any shape such as U-shaped, Z-shaped, hat-shaped, U-shaped, or any material such as metal, wood, plastic, etc. It may be composed of
