Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a modified snow melting roof structure for a house. More specifically, the present invention relates to a roof renovation structure having a function of uniformly melting snow on a new roof when renovating.

[0002]

2. Description of the Related Art Conventionally, the work of removing snow in a snowy region has been physically difficult and dangerous. Therefore, various methods of snow melting on the roof have been devised, such as a method of discharging hot water or water on the roof,
A method of circulating hot water, antifreeze liquid, hot air, etc. in a pipe arranged in the exterior part of the roof, a method of arranging a heating wire, a method of using hot water heated by solar heat, or JP-A-6-2.
There is a method of laying a sheet-shaped heating element like No. 399. Further, as a method of simultaneously providing a snow melting function when the roof is repaired, there is JP-A-5-230940.

[0003]

However, using a water discharge device and pipes, it is heavy to apply the snow melting function at the same time as the roof renovation, it takes a lot of time and labor for construction, and the device is subject to vibration or deterioration. There is a lot of disadvantage in applying the snow melting function at the same time as the repair in that the liquid leaks out due to the damage of the house and leads to the corrosion of the house, and the heating wire is likely to deteriorate its function due to cutting. In addition to the above-mentioned method, a method of providing a snow-melting function due to the repair has not been devised even in the method of disposing a sheet-shaped heating element as in JP-A-6-2399. Incidentally, JP-A-5-230
In No. 940, the target of renovation is limited to the roof tile roof, and the hollow pipe is buried with mortar, which is heavy and burdens the house, and it is disadvantageous in that it requires a longer construction period and cost. was there.

[0004]

In order to solve such a problem, the present invention has a structure in which, on various existing roofing materials, piers arranged at a predetermined interval parallel to the flow direction and piers arranged on the pier without a gap. Repair snow melting consisting of a backing material with heat insulation, an exterior part consisting of many new roof materials laid on the backing material, and a sheet-shaped heating element interposed between the backing material and the new roof material Since it has a roof structure, it is easy to install and lightweight, and can provide a beautiful new roof and roof snow melting function on various roofs at low cost.

Further, since the sheet-shaped heating element is interposed between the backing material and the new roofing material, heat radiation toward the interior of the house is prevented, and heat generated from the sheet-shaped heating element is prevented from entering the interior of the house. It proposes an efficient structure that can be used as a heat source for most of the snowmelt.

[0006]

The snow melting roof structure according to the present invention will be described below with reference to the drawings. 1 and 2 are explanatory views showing a typical example of the above-mentioned modified snow melting roof structure. In the figure, 1 is a splint, 2 is a backing material, 3 is a sheet-shaped heating element, 4 is a new roof material, and A is a roof substrate. , F is an existing roof composed of an asphalt roofing D and an existing roofing material E, which are laid as required, and G is an exterior part.

The roof substrate A is composed of rafters B and a ground plate C, and has a general structure in which the ground plate C is laid on the rafter B.

[0008] The existing roofing material E is a general roofing material laid on the roof substrate A, and although a metal thatched roof is shown in Figs. 1 and 2, the existing roofing material E is also flat. A thatched roof, a thatched roof, a roof tiled roof, a tile roof, a new tile roof, etc. may be used.

As shown in FIG. 1, the pier 1 is arranged on the existing roof F in parallel with the flow direction at a predetermined interval, and serves as a base for the backing material 2, and the backing material 2 and the new roof material 4 are mounted. It functions as a placing portion of a fixture α that is placed when placing it, and secures a space β as an air flow passage between the existing roofing material E and the backing material 2.

3 (a) and 3 (b) are perspective views showing a new thatched roof material 4 which constitutes the exterior part G. The new roof material 4 is a metal plate (color steel plate, copper plate, aluminum). Plate, titanium plate, stainless steel plate, sandwich steel plate, clad steel plate, etc.) are formed by roll forming, press forming, extrusion forming, or the like.

To explain further, the new roofing member 4 is in the form of an elongated plate, and one end portion in the width direction thereof is bent in a substantially U shape toward the lower side of the decorative surface 5, that is, the rear surface 6 side, and the stepped decorative surface 7 is formed. The male connecting portion 10 is formed with the insertion edge 8 and the decorative edge 5, and a substantially U-shaped hooking groove 9 is formed from the decorative surface 5, the stepped decorative surface 7 and the insertion edge 8.

At the other end of the decorative surface 5, a fitting groove 11 is formed which is bent to the upper side of the decorative surface 5 and has a substantially U-shaped cross section. A fitting edge 12 in which the end of the fitting edge is folded back in a U shape, and a fixing piece 13 in which the tip of the fitting edge 12 is bent downward and is bent substantially in parallel to the decorative surface 4 and bent outward in an L shape. The formed female connecting portion 14 is formed.

Further, a connecting piece 15 is formed by bending both end edges in the longitudinal direction of the decorative surface 5 on the back surface 6 side in a goby shape. In FIG. 3 (a), in order to strengthen the strength in the longitudinal direction and to prevent rainwater or the like from the outside from entering the inside due to the capillary phenomenon, the fitting groove 11 and the insertion edge 8 are provided with the recessed lines 16, respectively. 17 is formed.

As shown in FIG. 4, the backing material 2 is in the form of a long plate, and is formed by laying it on the rafter 1 without a gap. Further, the backing material 2 backs up the new roofing material 4 that constitutes the exterior part G, prevents deformation of the new roofing material 4 even when a load is applied such as work on the roof or snow, and the sheet-like material described later. The heat generated from the heating element 3 is insulated so that almost all of it contributes to snow melting, and the heat is prevented from escaping to the inside of the house (under the roof, etc.). Of course, in summer, even if the roof is heated by the sun, the heat is blocked from being transmitted to the inside of the house to prevent the temperature inside the house from rising, and it is also useful for soundproofing.

As the material of the backing material 2, sheathing board, sheathing insulation boat, plastic foam (urethane foam, nurate foam, phenol foam, etc.) particle board, wood composite board, wood wool cement board, composite panel (component panel). , Gypsum board, ALC board, etc., which have heat insulating properties.

Explaining further, the backing material 2 abuts the end surfaces in the horizontal direction, and in the direction from the eaves to the ridge as shown in FIG. It is fixed so as to form a triangular void β with A. This void β can function as a flow passage for fresh air and the like, and further promotes the functions of the backing material 2 such as a heat insulating material, a soundproofing material, and a humidity control material, and also prevents dew condensation to prevent the roof substrate A from being described later. It contributes to the prevention of corrosion of the new roofing material 4 and the like.

The sheet heating element 3 is a rectangular sheet as shown in FIG. 4, and is interposed between the backing material 2 and the new roofing material 4 as shown in FIGS. It is for supplying the heat necessary for snow melting. Further, the backing material 2 can be placed on the sheet-shaped heating element 3 without being fixed, but when fixing the sheet-shaped heating element 3 on the surface of the backing material 2, as shown in FIG. It can also be fixed and attached by various means such as an agent (not shown), an adhesive tape 18 and a stapler 19.

Using of about 430Kcal / H · m ^2, when the latent heat of fusion of ice about 78cal / g, melting snow capability when used as a 0.1 fresh snow specific gravity of about 1 day 13-130
It is about cm, and it can be applied not only to snowfall areas but also to most heavy snowfall areas. Of course, the calorific value of the sheet 20 can be adjustable.

The sheet 20 is not particularly specified as long as it has an appropriate electric resistance and causes a heat generation phenomenon when energized, but its composition is, for example, carbon fiber made of synthetic resin or the like. Bindered or mixed, pulp fiber and carbon fiber, or carbon particles, using those synthesized with a viscous material such as metal powder, among the above, because the carbon fibers are mixed so as to overlap each other, Even if one part of the sheet-shaped heat generating element 3 is broken or cut, the heat generation of other parts is not affected at all.

The insulating sheets 25 and 26 are made of a vinyl chloride film, a fluororesin film, an acrylic film, or the like, and by performing a laminating process or the like, effects such as surface protection, waterproofing, and electrical insulation are exhibited. The lead wires 23 and 24 are connected to a power source (not shown), and the resistance of the conductive material in the sheet 20 causes the entire sheet-shaped heating element 3 to generate heat, and the heat is transferred to the new roof material 4 of the exterior portion G. It will be melted in a wide area.

FIG. 6 (a) is a joint material 27 for connecting the new roofing materials 4 shown in FIGS. 3 (a) and 3 (b) in the longitudinal direction, and the same kind of material as the new roofing material 4 is equivalent.

As shown in FIG. 6 (d), which is an end view taken along the line Rolo, the locking portion 33 and the locking portion 33 are formed into a vase shape by folding back both side edges to the front side in the width direction and folding back the tips again. And an extended tongue piece 35 formed by folding back the tip of the extended portion 34 to the surface side.

The shape of the end face can be made substantially the same not only in the stitch portion 30 but also in the recess 31 and the rain return portion 32. That is, the siding plate 28 can be continuously formed by roll forming or the like. Further, in FIG. 6, in order to strengthen the connection in the vertical direction, a substantially central portion of the mouth portion 31 is extended to form a mouth tongue piece 31a.

As shown in FIG. 6 (c), the fitting plate 29 has a cross-sectional shape in which the left and right sides of the bottom surface 36 are folded back to form locking tongues 37 and formed into a mating bag shape. As shown in d), the connecting pieces 15 provided on both side edges of the decorative surface 5 of the new roofing material 4 are fitted and locked. FIG.
In (d), the new roofing material 4 is shown by a dotted line. More specifically, the fitting plate 29 is integrated with the mat portion 30 of the mat plate 28 by locking both ends by the locking portions 33, as shown in FIG. 6D. By locking the new roof member 4 with the joint member 27, the waterproof property is enhanced, and the snow melting performance is not deteriorated without being hindered by the sheet-shaped heating element 3 laid in advance.
