In order to achieve the above object, according to the present invention, a reinforcing frame is fixed to a roof beam so as to straddle a mountain portion of a folded plate roof, and a plate-like body is laid through the reinforcing frame.
With this configuration, if a reinforcing frame having sufficient strength to bear a load such as a plate-like body is used, the plate-like body such as a heat insulating material can be applied to the folded plate roof without being influenced by the deterioration of the folded plate. Can be laid.

  In the present invention, as described above, since a plate-like body such as a heat insulating material is laid without applying a load to the folded-plate roof, the life of the folded-plate roof can be extended, and the degraded folded-plate roof In the repair, it is possible to extend the useful life of the roof, improve heat insulation, etc., and achieve the energy saving screamed today.

  As an embodiment of the present invention, in the folded plate roof structure in which the folded plate is formed by fixing the folded plate to the roof beam, a reinforcing frame is provided so as to straddle the mountain portion of the folded plate roof, and the reinforcing frame is A structure in which a plate-like body such as a heat insulating material is laid on the upper surface of the folded plate roof through the reinforcing frame can be adopted.

In this configuration, a crosspiece frame extending over the entire length of the folded plate roof in the mountain length direction may be fixed to the reinforcing frame, and the plate-like body may be laid through the crosspiece frame.
If it does in this way, the support area of a plate-shaped object will increase and the support will be stabilized.

  FIG. 1 and FIG. 2 show an embodiment of the present invention. In this embodiment, as in the prior art, a tight frame 2 is fixed to a roof beam 1 in a wave shape in the length direction, A folded plate roof 3 is fixed to the roof beam 1. The folded plate roof 3 has a corrugated plate shape in which a folded plate 31 having both ends of an inverted trapezoidal frame shape extending in the lateral direction is connected to both end pieces 31a by a gouge 32.

  A tight frame 2 is provided in a wave shape along the roof beam 1 at a location corresponding to the roof beam 1 of the folded plate roof 3. The tight frame 2 reaches the mountain portion 3a of the folded plate roof 3 along the lower surface of one folded plate 31, then descends vertically to the roof beam 1, and further in the valley 3b of the folded plate roof 3. It consists of a member 21 that is screwed to the roof beam 1 at its end and an L-shaped member 22 that extends along the lower surface of the other folded plate 31 and extends downward. A bolt 33 and a nut 34 are fixed between the vertical pieces of the members 21 and 22 with a suspension 33 interposed therebetween, and the folded plate roof 3 (folded plate 31) is fixed to the roof beam 1 by the tight frame 2. . The configuration so far is the same as the conventional one, and various other conventional configurations can be adopted.

  In this embodiment, the folded plate roof 3 is repaired. A plate-like reinforcing frame 40 is provided so as to straddle the mountain portion 3 a of the folded plate roof 3, and the folded plate roof is provided via the reinforcing frame 40. 3 The heat insulating material 5 is laid on the upper surface. The reinforcing frame 40 is made of a steel plate and has an isosceles trapezoidal frame shape with its both ends extending in the lateral direction, and its end piece is fixed to the roof beam 1 with screws 9. A sealing washer 9 a is interposed in the screw 9. The reinforcing frame 40 is preferably made of the same metal as the roof beam 1, but may be made of a different metal as long as there is no trouble such as electric corrosion.

A cross-sectionally U-shaped crosspiece frame 50 is fixedly attached to the peak portion of the reinforcing frame 40 by covering pieces 51 at both ends thereof. That is, the crosspiece frame 50 has both ends of a U-shaped cross-section facing downward. Each of the pieces 51 and 51 at both ends along the oblique side of the reinforcement frame 40, and the pieces 51 and 51 at both ends fit on the shoulder and are formed on the oblique side. The fixed frame frame 50 is fixed by an immovable fit that covers the peak portion of the reinforcing frame 40 along the entire length of the peak portion 3 a of the folded plate roof 3. For this reason, the crosspiece frame 50 is fitted in the reinforcement frame 40 fixed to each roof beam 1 in the length direction, and is supported by at least two points.

The heat insulating material 5 is placed on the crosspiece frame 50, and the screw 6 through the iron disk 8 penetrates the heat insulating material 5 and is screwed into the crosspiece frame 50 at an appropriate place. The material 5 is fixed to the crosspiece frame 50, and the entire folded plate roof 3 is covered with the heat insulating material 5.
A waterproof sheet 7 is laid over the entire upper surface of the heat insulating material 5, and this waterproof sheet 7 is fixed to the heat insulating material 5 by electromagnetic induction heating via a disk plate 8 at an appropriate location.

  On the waterproof sheet 7 (the heat insulating material 5), a solar cell unit 60 and the like are appropriately installed through a gantry 61. For fixing the pedestal 61, a screw 6 for fixing the disk plate 8 protrudes the waterproof sheet 7, and means such as a nut fixing to the protruding bolt 6a is adopted. The protruding portion of the screw 6 performs a waterproofing process 70.

  In this embodiment, since I-shaped steel is used for the roof beam 1, even when a hole is made, the chips at the time of making the hole are less likely to fall down, and the influence of the chips on indoor installations is as small as possible. Furthermore, since it is not necessary to make a hole in the portion of the folded plate 31 alone, even if a defect occurs in the repaired waterproof layer, the folded half roof, which is an existing waterproof layer, retains a certain waterproof function. There is no fear of being connected immediately, and a double waterproof function can be demonstrated.

  In addition, it can replace with the heat insulating material 5, and can also employ | adopt various plate-shaped bodies, such as a panel. Of course, the present invention can be applied not only to the repair of the folded-plate roof 3 but also to the production of a new folded-plate roof 3. Further, the connection of the folded plate 31 is not limited to the gouge fastening, and other various means can be employed.
