特徴、効果がある。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for repairing an existing roof by constructing a new roof having a stepped roof on an existing low-slope roof, applying a new rafter and a base material. Things. 2. Description of the Related Art In general, in order to repair a roof with a slope of 2 or less to a stepped roof, a base having a predetermined slope is formed on an existing roof in a mini-roof structure, and then a new roof is roofed. It was a construction method. [0003] However, this mini-roof construction has become a completely new basement structure of the roof, requires a long time for construction on a high roof, and requires various materials and many man-made materials. In other words, the cost was greatly increased. In addition, the new mini-shed structure and the existing roof had to be solidly cast due to their strength, and metal fittings had to be prepared. [0004] In order to eliminate the above-mentioned drawbacks, the present invention provides a new roof base, a metal fitting for mounting the same, and a wood piece which can be easily processed to change in gradient. The present invention proposes a roof repair method in which a new roof having a slope of 2.5 or more can be easily laid by simply combining a roof with a desired predetermined slope by processing the roof into a dimension promoted by the coefficient. An embodiment of the roof repair method according to the present invention will be described below in detail with reference to the drawings. That is, FIG. 1 is an explanatory view showing a typical example of the present invention, and FIG.
(New tile roof), (b) (roofed roof) is an explanatory drawing showing the eaves, 1 is the existing roof, 2 is the old eave, 2a is the new eave, 3 is the arabesque, 4 is the renovation Arabesque, 5 is a ridge, 6 is a ridge, 7 is a wrapper cover, 8 is a tarpaulin, 9 is a new roof, 10 is a new rafter, 11 is a spacer, 12 is a tight frame material, and 13 is the top of a tight frame material 12. The surface, 14 is a new base material, 15 is a new base material, and 16 is a new roof material. The existing roof 1 is a tile bar, a flat roof, a new tile roof, or another existing roof. The existing roof 1 functions as a foundation for the new roof 9 without removing the existing roof 1. As shown in FIGS. 2 (a) and 2 (b), the eaves are composed of two layers: a new eave 2a and an old eave 2. The arabesque 3 and the renovation arabes 4 are placed on the old eave 2. A new eave part 2a is formed. Wing section 5 removes the existing building and newly builds a ridge tree 6,
It is configured using the ridge cover 7 and the like. Reference numeral 8 denotes a waterproof sheet, for example, asphalt roofing, which is laid on the new foundation 15 or on the existing roof 1 from the old eave 2 to the ridge 5. [0009] The new roof 9 is a new rafter 1 on the existing roof 1.
0, the new base material 14, and the waterproof sheet 8 were constructed in this order, and the height of the new rafter 10 increases from the eave to the ridge. For example, wood, metal (including extrusion and molding)
This new rafter 1
At 0, it is fixed at a predetermined pitch at a position and size such that it is located on the gradient line of the new roof 9. That is, as shown in FIG. 3, the new rafter 10 comprises two members, a spacer 11 as shown in FIGS. 4A to 4E and a tight frame member 12 as shown in FIG. Is formed such that the top surface 13 of the tight frame member 12 exists at the gradient of the above-described dimensions, for example, as shown in FIGS. The tight frame 12 has a fixed height as shown in FIG. 5, for example, and is formed mainly of a metal material, and is used for fixing a new base material 14 made of a kind of plywood or wood wool cement board. Things. Of course, a member made of wood and having a polygonal cross section may be used as long as it has the same function. The new roofing material 16 is desirably a metal material that is lightweight, easy to construct, and has sufficient durability.
The construction is carried out as shown in FIG. Of course, general-purpose products other than metal roofing materials may be used. Next, the construction order of the roof repair method according to the present invention will be described with reference to FIGS. First, the existing roof 1
It is assumed that the slope of (gable) is two-dimensions, this is a three-dimension gradient, and a new roof 9 is formed thereon. Therefore, a new rafter 10 conforming to the set gradient is integrally fixed to the existing roof 1 at a predetermined pitch with a nail or a screw or the like so that the top surface 13 of the tight frame material 12 is existing on the gradient line. At this time, the new rafter 10 may be formed by fixing the spacer 11 and fixing the tight frame 12 thereon. If the length of the fixture becomes too large in the vicinity of the ridge 5, it may be easy to drive nails or the like via the metal reinforcing member 17 as shown in FIG. Next, a new base material 14 such as plywood is laid and fixed on the tight frame 12, and a waterproof sheet 8 is laid thereon to form a new base material 15. At this time, the ridge of the existing roof 1 has already been removed. Therefore, the repairing arabesque 4 is fixed and locked to the eaves via the arabesque stopper 3 made of resin as shown in FIG. On the other hand, although not shown, the keraba is provided with a two-member keraba base. Next, as shown in FIG. 2, a new stepped roofing material 16 is laid through a backup material 16a as shown in FIG. Such work is repeatedly performed up to the ridge. Thereafter, the purlin 6 is fixed to the new groundwork 15 in the ridge section, the purlin 6 is covered with the ridge cover 7, and the ridge 6 is fixed to the purlin 6, and necessary portions (not shown) may be filled with face doors and caulking material. . The keraba is provided with a keraba cap every time a new roofing material 16 is constructed. The above description is only one embodiment of the roof repair method according to the present invention. As shown in FIG. 7, a heat insulating material A such as a polyurethane foam is used between the existing roof 1, the new rafter 10 and the new base material 14. Can be filled by intervening or in-situ foaming. Although not shown, the keraba portion covers the opening with a base of plywood, and a metal plate is laid thereon. As described above, according to the roof repair method according to the present invention, it is possible to form a roof base having no problem in waterproofness with a small number of members even with a low gradient roof. Easy-to-process wood is prepared according to the dimensions of several target slopes, and a tight frame material of a certain size is added to this to construct a new rafter. The tight frame material has sufficient strength and is lightweight, and the load on the entire roof is small. Since the low gradient is configured to be two dimensions and five minutes or more, the waterproofness and design properties are greatly improved. By installing plastic foam (including on-site spraying) in the space between the new rafters and the new groundwork, the heat insulation of the roof is remarkably improved. There are features and effects.
