ければならないことが多々あつた。 When an existing metal sheet roof, such as the so-called tile rod type or seam roof type, in which metal sheets are connected to each other by rising joints, is damaged due to aging or other reasons, the damage is localized and clearly visible. In that case,
It may be possible to repair just that part. However, in cases where the damage was not obvious or over a wide area, the entire metal plate (commonly known as the gutter board) had to be replaced. Normally, this complete reroofing is difficult because the rising joints of the metal plates are formed in the form of tile rods or seams, making them a sturdy structural part, and it is difficult to remove the metal plates themselves. As a result of removing the metal plate, not only the tarpaulin sheet but also the roofing board was damaged, and in the end, the entire roofing board had to be replaced, which not only caused poor work efficiency but also a large economic loss. Furthermore, during renovations, it is necessary to temporarily fence with tents or set up scaffolding in case of rain during the construction period, and above all, the use of the structure must be temporarily suspended, which may cause inconvenience. Something happened. Furthermore, as a construction method for repairing such roofs, for example,
−73524, JP-A-52-98319, U.S. Patent Publication No. 1983-
There is number 167524. However, in these construction methods, no heat insulating material is involved, or even if a heat insulating material is present, all the gaps between the rising joints are filled. As a result, moisture from anticipated condensation would accumulate between the existing roof and the insulation material, causing disadvantages such as corrosion of the existing roof and the base of the new roof. Furthermore, in the above-mentioned repair method, it is inefficient because it is necessary to individually cut and lay or fill the insulation material between the rising joints provided at 450 mm intervals. Since large gaps are formed between the two, there is a drawback that the insulation material cannot be used effectively. In addition, in snowy regions, the upright joints may be significantly deformed, making them unusable as support parts and often requiring repair.

法を提案するものである。 The present invention can be applied to existing metal sheet roofs that have become aging and would normally require replacement, or existing metal sheet roofs that have deteriorated in insulation performance due to water leakage or other reasons, even if they are not old. When renovating a roof in which metal plates are connected by rising joints, the existing metal plates and structure of the existing metal plate roof are left as is, and multiple special horizontal beams are installed on the existing roof. Fix it with nails etc. at appropriate intervals,
A heat insulating material is laid on the horizontal beams to improve insulation performance, soundproofing, dew condensation resistance, corrosion resistance, and flatness as a base material, and a roof surface member is laid using the horizontal beams as a support for the new roof. By doing so, we propose a construction method that is simple and quick, and allows for renovations without interrupting the residence.

ものである。 The construction method according to the present invention will be explained in detail below using the drawings. Figures 1a and 1b are a cross-sectional view and a partially cutaway perspective view showing one typical example of a roof repaired using the above construction method, and A is an existing metal sheet roof (hereinafter simply referred to as the existing roof). , B is the horizontal beam, C is the space,
D indicates a heat insulating material, and E indicates a newly installed metal sheet roof (hereinafter simply referred to as a newly installed roof). To explain further,
For example, the existing roof A can be constructed by using roofing boards 2 laid on a bridge over rafters 1 as a base structure, and then a waterproof sheet 3 such as asphalt felt is stretched on top of it to form the base, and then a length called gutter board is formed. Metal plates 4 having rising portions 4a at both ends along the direction are laid adjacently so that the groove direction runs from the eave to the eaves, and a hanger 5 (as the case may be) is placed between each rising portion 4a of each adjacent metal plate 4. (Of course, you can use solid wood, which is the original tile rod, or you can use an inverted hat type hanger as shown in the figure.)
After fixing with nails 8, a cap material 6 is placed on the metal plate 4, and the stacked edges of the rising part 4a of the metal plate 4, the hanger 5, and the cap material 6 are tightened with a seam winder or the like, and the three parts are tightened. By winding and meshing together, each metal plate 4 has its rising connecting portion 7.
They are connected together and have a specified metal sheet roof.

任意の厚さの大型パネルである。 Further, the horizontal beams B are installed on the existing roof A at appropriate intervals, for example, at a pitch of about 450 mm, so as to intersect with the rising connecting portions 7 of the existing roof A, and are connected to the rafters 1 from above the existing roof A via nails 8. to function as a supporting part for the newly installed roof member, and to fill the void C as described below.
This is useful for preventing direct contact between the heat insulating material D and the existing roof A. As shown in FIG. 2, the structure of the horizontal beam B is such that a fitting portion 9 is formed by cutting out a portion of the existing roof A that intersects with the rising connecting portion 7. The width L of the fitting portion 9 is set to be equal to the width l of the rising connecting portion 7, or approximately l+1 to 10 mm. In addition, the notch height H of the horizontal bar B is the height h of the rising connecting portion 7 and the relationship H<h.
Create a gap of Δt 1 between each of the four metal plates of the existing roof A and the horizontal beam B.
It is formed between the lower surface 10 and used for air cycles, etc., and Δt 2 is about 3 to 20 mm. Further, the width W of the horizontal bar B is about 10 to 60 mm, usually about 28 mm. Of course, the dimensions of the horizontal beam B can be arbitrarily set depending on the size of the existing roof A. In the present invention, the heat insulating material D mainly aims to improve the heat insulating performance of the roof structure, and also functions as a sound absorbing material and a cushioning material. Typical examples include two types: a single insulation material and a composite of insulation material and other components. Specific examples of single substances include vinyl chloride foam, polyethylene foam, polystyrene foam, polyurethane foam, polyisocyanurate foam, phenol foam, or these foams combined with glass fiber, inorganic lightweight aggregate (perlite grains,
Shirasu balloon), with a compressive strength of 0.4 Kg/cm 2 or more, preferably 1 Kg/cm 2 or more,
Closed cell foam is better than open cell foam. Typical examples of complexes include the Kanatsupe structure and the Sandermansch structure, as shown in FIGS. 3a and 3b. That is, Fig. a shows a heat insulating material D in which a heat insulating material 12 and a substrate 13 are integrally formed, and Fig. b shows a heat insulating material D in which the heat insulating material 12 is sandwiched between a sheet material 14 and a substrate 13. The base material 13 mainly functions as a conventional field board, such as plywood, sheathing board, slate board, wood wool cement board, gypsum board, etc.
Asphalt felt, kraft paper, asbestos paper, gypsum paper, glass fiber non-woven fabric, synthetic resin film, cardboard, etc., laminated with one or more types, or these laminated with metal foil (Al, Cu, Pb). This is what I did.
In particular, in the sandwich structure, the tensile strength of the sheet material 14 is greater than the bending strength of the heat insulating material 12, and the strength of the heat insulating material D itself is greater than the bending strength of the heat insulating material 12. In addition, sheet-like material 1
4. Paper, in particular, can be subjected to a known waterproofing treatment. Further, the sheet-like material 14 is a heat insulating material 12
This is to disperse localized pressure on the area. Furthermore, the size of the insulation material D is usually 1800mm x 900mm x
Large panels of arbitrary thickness.

As shown in the figure, the horizontal bar B is arranged at a pitch of 450 mm so as to be orthogonal to the rising connecting part (tile bar) 7, and nails 8 are driven into the vicinity thereof as shown in Figure 1.
is fixed on roof A. Next, a heat insulating material D such as that shown in FIG. To be fixed. Therefore, using this heat insulating material D as a base, a new waterproof sheet 15 such as asphalt felt, roof surface members 16, hangers 17, and cap material 18 were attached using the same method as for the existing roof A illustrated in FIG. if,
A renovated roof, a so-called new roof, is completed, which has a rising connecting portion 19 and a rising portion 19a corresponding to the rising connecting portion 7 and rising portion 4a of the existing roof A, and whose appearance is exactly the same before and after the renovation.

Or, conversely, if you desire a different roof appearance, you are not limited to the above-mentioned examples, and you can freely select and adopt roof members made of other desired materials such as metal plates, slate plates, roof tiles, etc. , it is possible to realize a renovated roof with a desired appearance, and of course, the construction thereof is not limited to the above-mentioned embodiments. 7,7
It goes without saying that any configuration may be adopted as long as the horizontal bar B is used for... That is, it is also possible to construct the roof surface member 16 directly on top of the heat insulating material 12,
In this case, the roof member 16 is directly attached to the upper surface 11 of the horizontal beam B.
Since the heat insulating material 12 in this case is a foamed synthetic resin (foam) having elasticity, if the roof surface member 16 is formed of a metal plate, the central part of the metal plate However, the elasticity of the heat insulating material 12 can eliminate the voids and prevent vibrations and noise caused by wind and rain.

ますことができる特徴がある。 As mentioned above, according to the construction method according to the present invention, the existing roof is left as it is and new roof members are installed on top of it, so it is easier to work with than the conventional repair method that removes the existing roof. It is much more economical, and does not require temporary enclosures such as tents in case of rain or scaffolding for work.Furthermore, there is no need to interrupt the residence during renovation work, and there is no need for temporary enclosures such as tents in case of rain. In such cases, it is possible to temporarily cover the construction site to protect the parts used.

る。 In particular, the particularly important effect of this invention is that even if the existing roof is made of metal sheets and would otherwise require replacement due to aging, the rising joints of the roof are sufficiently strong in terms of structure. In many cases, the roof remains intact, and if you don't forcefully remove that part, the roofing board itself will work together with the existing metal plate on the surface, and it will not be able to fully function as a base structure. Focusing on what can be done, fixing of newly installed roof members is done by fixing a particularly sturdy rising joint (generally, rafters are often located below this part, in which case the rafters themselves also serve as a support part). Or, just by using the newly installed horizontal bars with reliable strength and shape, you can easily and efficiently install strong fixings. Because of its elasticity, it comes into contact with the horizontal crosspiece, which prevents the insulation material from shifting. Furthermore, because a space was created between the existing roof and the insulation material, and the insulation material was laid without any gaps, it has excellent insulation properties, soundproofing properties, and corrosion resistance.
