Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a method for renovating a roof by constructing a new roof sheet while leaving the existing roof intact.

[Background Art] Conventionally, when renovating a roof, the existing old roof was removed and a new roof was constructed.

For this reason, in the past, there were problems in that construction was time-consuming, the construction work was large-scale, and the construction work would be problematic if there was a light rain. For this reason, it has been considered to construct new roof shingles while leaving the existing roof intact, but the joints between the existing roof shingles protrude in three directions, which obstructs construction and makes construction difficult. The problem was that the shapes of the joints of existing roof panels differed from site to site, making construction even more difficult.

[Objective of the Invention 1 The present invention was invented in view of the above-mentioned conventional problems, and its object is to be able to construct a new roof sheet while leaving the existing roof intact, and to To provide a roof renovation method that can be easily constructed without being disturbed by joints between existing roof plates.

[Disclosure of the Invention] In the roof renovation method of the present invention, mounting is carried out by covering and fixing a metal fitting 5 on the mountain portion 4 of an existing roof 3, which is a joint 2 between existing roof panels 1, and the mounting is carried out using a metal fitting. The joining part 2 of the existing roof panels 1 is located within the protruding part 6 of the downward opening of the upper part of the roof panel 5, and the new roof panel 7 is placed on one side of the existing roof 3, and the installation is done using the metal fittings 5. A new roof board 7 is installed, and by adopting this method, the above-mentioned
The object of the present invention has been achieved.

The present invention will be explained in detail below with reference to Examples. The existing roof 3 is constructed by covering an existing roof plate 1 made of corrugated metal plate (square corrugated plate in the illustrated embodiment). In the figure, 8 is a support like a tight frame installed on a mock material 9 like an existing main building, and an existing roof board 1 is placed along this support 8. The ends of the existing roof panels 1 are joined together at the top of the roof. When joining existing roof panels 1 to each other, for example, the ends of one of the existing roof panels 1 are engaged with a hanger 10, and the hanger 10 is supported by bolts 11 at 8.
, fixed with nuts 12, and further attached to the other existing roof sheet 1.
They are joined by hooking and engaging the ends of the two.

The method of this joining is not limited to the one described above, but varies depending on the site (for example, joining by caulking, joining with bolts, nuts, or other joining other than the above), but in any case, the joining part 2 is connected to the roof. It protrudes upward from the peak 4 of No. 3. In the figure, reference numeral 5 indicates a metal fitting, and the mounting part 14 is extended outward from the bottom of both sides of the protruding part 6 of the downward opening in the shape of an inverted U. The fixing portion 13 is extended in a letter-shaped manner. Then,
When attaching the metal fitting 5, the fixing part 13 is placed over the peak part 4 of the existing roof 3, the joint part 2 is positioned inside the protruding part 6, and the fixing part 13 is fixed with the fixing part 15 to the existing roof. Both supports of 3 are fixed to 8. After the metal fittings 5 have been installed in this way, the metal fittings 5 are then fitted with new roof panels 7.

When installing a new roof board 7, it is installed as shown in FIG. 1, for example. In Figure 1,
16 is a spacer made of synthetic resin such as polyacetal that is attached to the upper part of the protruding part 6 of the metal fitting 5,
The spacer 16 is attached to the bolt 18 using the screw hole 17 at the bottom.
The main metal fitting 20 is fixed to the upper part of the spacer 16 with bolts 19. The upper surface of the main metal fitting 20 is one-stage 2 with one side lowered.
1, and a new hanger 23 is attached to this concave portion 21 with a bolt 19 via a mounting seat 22. Here, to remove and attach one spacer 16, loosen the bolt 19 that goes through the seat 22.
The fitting protrusion 24 on the upper part of the main fitting 20 fits into the hole 25 of the main fitting 20, so that it does not come off from the main fitting 20. The hanger 231 engages the engaging portion 26° at the end of one new roof plate 7, and engages the engaged portion 27 at the end of the adjacent new roof 7 via the hanger 23. portion 261-'' is engaged, thereby constructing a new roof sheet 7. In this case, the end of the new roof sheet 7 is placed on the main metal fitting 20. In the above embodiment, an example was shown in which a new roof plate 7 was joined using a new roof plate 23, but there are other methods for raising and lowering this, for example, using a bolt 28 as shown in Fig. 3. The mounting may be done by protruding upward from the metal fitting 5 and joining the ends of adjacent new roof outsides 7 with this fixing port 28, or by other methods. 4-1, the spacer 16 is provided, and the example shown in FIG. 3 is not provided with the spacer 16, but the spacer 16 may or may not be provided. When providing the spacer 16, a synthetic resin with heat insulating properties is interposed between the existing metal roof plate 1 and the new metal roof plate 7, causing the spacer to fly away, and so-called heat bridges do not occur. Further, a heat insulating material or a sound deadening material may be interposed between the existing roof panel 1 and the new roof panel 7 as required.

[Effects of the Invention] As described above, in the present invention, the mounting is done by covering the mountain part of the existing roof, which is the joint between existing roof panels, with a metal fitting and fixing it, and then attaching the new roof to the top of the existing roof. □1 The new roof shingles are placed and installed by attaching the new roof shingles to the metal fittings, so there is no need to remove the existing roof shingles. Renovation work can be done quickly and easily. In addition, since the joint between the existing roof panels is located within the protruding part of the downward opening of the metal fitting, even if there is a joint that protrudes upward on the peak of the existing roof, the joint Installation can be done by attaching the metal fittings and then attaching the new roof shingles to this without being hindered by the roof.Furthermore, even if the shape of the joint of the existing roof shingles is different, the installation can be done within the protruding part of the metal fittings. The joints have different shapes for each site. It can be removed in two steps, and new roof shingles can be installed on various existing roofs by attaching metal fittings.
