Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repair structure in which a special base sheet is interposed between a new roof and an existing roof material without removing the existing asbestos slate roof.

[0002]

2. Description of the Related Art Generally, roofs using asbestos slate type roofing materials are removed by removing all of the existing roofing materials or by placing rafters on the existing roof as a new ground and laying a field board on it. The structure was one of forming a new roofing material and then forming a new roofing material.

[0003]

However, in order to remove the existing roof and form a new roof, it is necessary to stop living for a long time, and it is difficult to dispose of the roof material that has become a waste. In addition, there is a disadvantage that the total cost for repair is enormous. Also, if a new base material is formed on the existing roof and the roof is renovated by forming a new roofing material on it, it is not necessary to stop living, and this is often a significant improvement over the above. However, the cost was inevitable due to the increase in the number of necessary parts, and the addition of special members and soundproofing materials for the accommodation of keraba, eaves, etc. had to be done.
Furthermore, the existing roof of asbestos slate roofing material is weak against external pressure,
The rafters did not make uniform surface contact with the overlapped parts, which not only lacked stability, but also had the disadvantage of damaging the overlapping part of the existing roof material when the new roof was renovated.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, the present invention eliminates such drawbacks by forming a gap between roof members of an existing asbestos slate roof, that is, a space having at least a triangular cross section between planes parallel to the so-called roof slope. We propose a refurbished structure for asbestos slate roof by filling a base sheet with plastic insulation material that is strong, waterproof and nailable to form a new flat base, and roofing any new roof on the base. It is a thing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the asbestos slate roof repair structure according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a cross-sectional view showing a typical example of the invention described above. Reference numeral 1 is an existing roof, which is formed of rafters 2, field boards 3, waterproof sheets 4, and asbestos slate roofing materials 5.

Reference numeral 6 denotes a new base sheet, as shown in FIG. 1, which is a cross section 3 formed between straight lines a in which the apex of the surface of the asbestos slate roofing material 5 of the existing roof 1 is drawn parallel to the slope of the existing roof 1.
The rectangular voids 9 are filled. To explain further, as shown in FIG. 2, the new base sheet 6 is composed of a sheet 7 and a plastic foam 8 having a triangular cross section provided with a backup material also serving as a compression resistant material, a dimension adjusting material, and a filler. ..

That is, the sheet 7 functions as a waterproof material and a connecting material, and is made of one type of aluminum kraft paper, asphalt felt, plastic sheet, lead foil, or the like, or a flexible type obtained by laminating one or more of these types. The sheet has a width of about 200 to 700 mm and a length of about 2000 to 3000 mm. Also, is it made of one kind of plastic foam 8, polyurethane foam, polyisocyanurate foam, phenol foam, polystyrene foam, vinyl chloride foam, etc., and has a compressive strength of 0.5 to 3 kg / cm ² and a cross section corresponding to the void 9? , Slightly smaller than this. Sheet 7
An adhesive, a double-sided tape, or the like may be used to integrate the plastic foam 8 and the plastic foam 8. Of course, they can be formed integrally by self-adhesiveness when forming the foam.

Reference numeral 10 denotes a new roof, for example, a metal plate horizontal thatched roof shown in FIG. 1, a roof tiled roof shown in FIG. 3, and a roof shown in FIG.
1 is provided, such as a flat roof as shown in FIG. 5 and a roof with a roof 13 as shown in FIG. That is, the new roof sheet 11 provided on the existing roof 1 is a new roof material 11 which is directly formed on the flat new base material or through the core material 14.

In FIG. 1, the core material 1 as shown in FIG. 6 is used.
4. The metal horizontal stepping roofing material 12 (hereinafter, simply referred to as a roofing material) is applied in order from the eaves to the ridge via the fixtures 15. The core material 14 has W = 900 and L = 18.
It is made of one kind of a sheathing insulation board having a thickness of about 00 mm and a thickness t of about 7 to 15 mm, rockwool treated with water and heat-treated plastic foam.

Next, the construction sequence of the asbestos slate roof repair structure according to the present invention will be described with reference to FIG. First, a new base sheet 6 is laminated on the asbestos slate roof material 5 of the existing roof 1 made of the existing asbestos slate roof material 5 in order from each step in the eaves direction (not shown) toward the ridge to form a new base material.
At this time, the upper end 7a of the sheet 7 is laminated on the lower end of the upper asbestos slate roofing material 5, and the lower end 7b is laminated on the lower seat 7
Is laminated on the upper end portion 7a of the.

Next, a start material which also serves as arabesque is fixed to the eaves end (not shown), and one end of a core material 14 as shown in FIG. 6 is placed on the end of this start material. Next, the first roof material 1
2, for example, the locking portion 12a of the roof material 12 having a cross section as shown in FIG. 7 is engaged with the end portion of the start material (not shown), and the fixing portion 12c at the other end is fixed to the rafter 2 via the fixture 15. ..

Next, one end of the core material 14 used in the second stage is placed on the fixed portion 12c, and the engaging portion 12b of the roof material 12 is provided with the locking portion 12a of the second stage roof material 12. Lock. Therefore, in order to roof the new roof 10, the above-described steps may be sequentially repeated to reach the building.

What has been described above is only one example of the asbestos slate roof repair structure according to the present invention.
As the material, a roof material 12 having a shape as shown in FIGS. 8A to 8D or a well-known roof material 12 not shown can be used. Furthermore, as shown in FIG. 9, a spacer 16 made of one kind of material similar to the core material 14 that functions as a heat insulating material, a waterproof material, a sound insulating material, a humidity control material, and a cushion material.
Is arranged on the new base sheet 6, or as shown in FIG.
It can also be formed as shown in (c).

That is, (a) shows a new base sheet 6 in which a plurality of stages (for example, three stages) of plastic homes 8 are formed at a predetermined pitch P, and (b) shows a longitudinal direction of the plastic homes 8 at a pitch of 20 to 40 cm, for example. A new base sheet 6 having a structure in which a break 6a is inserted in the base plate so as to follow the severe unevenness of the asbestos slate roofing material 5, (c) in the figure, a bent portion 6b having a plurality of steps is formed between the plastic homes 8 in parallel with the building It is the new base sheet 6 which was done. In addition, FIG.
Is a sheet 7 obtained by laminating an aluminum foil 17, a kraft paper 18, and a plastic film 19 on the sheet 7.
(B) The figure shows asphalt felt 20 and kraft paper 18
7 is a sheet 7 in which the asphalt felt 20, the lead foil 21 and the kraft paper 18 are laminated.

[0015]

As described above, according to the modified structure of the asbestos slate roof according to the present invention, since the new base sheet is used on the roof material of the existing roof, a flat new base can be easily formed. It can be renovated without destroying the existing roof and without discontinuing residence. Unlike before, the advantages of asbestos slate roofing materials can be fully utilized. Features such as
effective.
