DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention has a heat insulating effect, and a heat insulating base material for a roof characterized in that the bottom surfaces of adjacent base materials are substantially flat. It is about structure.

[Conventional technology]

In the conventional side-roofed roof, in order to enhance the heat-insulating effect, there are many foundation structures in which a heat insulating material is laid under a roof plate or a space is provided. An example thereof will be described with reference to FIGS. 6 and 7.

First, FIG. 6 (a) shows a double wood board as a heat insulating material, in which a tree (5) is set on a purlin (23), and a lower wood board (24) is placed thereon. Lay. Further, the upper wooden fleece board (25) is laid on top of it so that a step is formed according to the roofing feet of the horizontal roof shingle (15). FIG. 6 (b) is a cross-sectional view taken along the line AA of FIG.

As another example, there is one in which an air layer is provided as shown in FIG. 7 to enhance the heat insulating effect. In this method, a lower wooden blank board (24) is laid on the main house (23), and a tree (5) is placed thereon.
On top of that, the upper wooden fleece board (25) is laid so as to overlap with the roof of the horizontal roof shingle (15) so as to form steps according to the roofing feet. FIG. 7 (b) is a cross-sectional view taken along the line BB. As shown in FIG.
An air layer (26) is formed between (5).

Also, as shown in FIG. 8, a wooden blanket (2
There is also a method in which 7) is laid while partially overlapping, and a shingle is laid on it.

[Problems to be solved by the invention]

The conventional technique of double-laying the wood wool board or providing the air layer in FIGS. 6 and 7 requires a lot of trouble and time for construction due to its complicated structure.

Also, as shown in Fig. 8, the method of laying a wooden blanket on a rafter while partially overlapping it is simple in structure, but has little heat insulation, and when a ceiling board is not stretched like a gymnasium or factory, indoors The steps of the wooden wool board (27) are visible.

When building a building, the color of the ceiling is generally a bright color such as cream or white, but the color of the shingle is deeply related to the design of the building, so the color of the roof plate will be a certain amount until the designer decides the color etc. It takes time. Since the roof shingle is laid on the roof while laying the base material, it was not possible to lay the base material until the design of the roof plate was decided. If only the base material is laid first, it must be cured in case of rain or wind, and if not cured, the base material that also serves as the ceiling plate will have a rain stain. This is because the base material may fly off due to the wind.

The present invention solves these problems, has a simple structure while having a heat insulating effect, has a good appearance without stretching a ceiling plate, and furthermore, a base material even if the design of the roof plate is not determined. And a roof structure using the same.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a heat insulating base material for a roof with a waterproof outer skin material and a metal inner skin material.

Then, the shape of the cross section when cut in the eaves ridge direction is formed in a substantially gradient shape so that the bottom surface of the heat insulating base material for the roof extends along the base such as a rafter. In other words, the thickness of the heat insulating base material for the roof increases from the ridge side edge toward the eave side edge.

Furthermore, a concave portion that opens laterally is formed on one of the ridge side edge and the eaves side edge of the thermal insulation base material for the roof, and a convex portion that protrudes in the lateral direction and fits into the concave portion is formed on the other side. Have been.

Then, when the concave and convex parts are fitted, the roof insulation base material located on the lower level is covered with the eaves side edge of the roof insulation base material located on the upper level. The upper part of the eaves side edge of the heat insulating base material protrudes.

This roof insulation base material is laid on a base such as a bark, but is attached to the ridge side of the roof insulation base material and to the part where the eaves side edge of the roof insulation base material of the upper tier is covered. The metal fittings are placed and fixed to the foundation together with the heat insulating foundation material for the roof with fasteners. Then, the ridge-side edge of the roof insulating base material fixed in this way and the edge of the roof insulating base material located on the upper stage are provided on the other side in the concave portion provided on one side. The projections are fitted and connected.

Repeat this method, laying the roof insulation base material on the entire roof, then hooking the suspension on the ridge side edge of the roof shingle that is laid on the roof insulation foundation, and placing the suspension on the mounting bracket The roof plate is stopped by attaching it.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the heat insulating base material (1) for the roof is made of a metal inner skin material (2) and a waterproof outer skin material (3) made of aluminum foil or waterproof paper. The inside is filled with a foamed heat insulating material (4).

The heat insulating base material for roof (1) has a substantially gradient cross section when cut in the eaves ridge direction, that is, the thickness of the heat insulating base material increases from the ridge side edge to the eaves side edge. So that the bottom surface (11) of the metal endothelial material (2) follows the tree (5).

At the ridge side edge of the heat insulating base material for roof (1), a metal inner skin material (2) is raised, and further bent into a substantially L-shape to form a convex portion (6) projecting in the lateral direction. After being bent inward, the tip is further folded back to form an upper edge bent portion (7).

At the eave-side edge of the heat insulating base material for roof (1), a metal inner skin material (2) is raised to open a concave portion (8) having a shape fitting with the above-mentioned convex portion (6) in the lateral direction. Forming
After extending the tip, it is raised substantially at a right angle to form a rising portion (9), and the tip is folded back to form a lower edge bent portion (10).

Further, the bottom surface (11) may be provided with shallow irregularities (11a) as shown in FIG. 2 to increase the strength.

As the material of the outer skin material (3), a material having waterproofness such as aluminum foil or waterproof paper is used. Top surface (12) of shell material (3)
A roofing shingle (15) is placed on the, and the ridge side edge of the upper surface (12) is raised to become a standing part (13). The lower edge (14), which is the eave-side edge of the upper surface (12), may be bent downward as shown.

A slight gap is provided between the upright portion (13) of the outer skin material (3) and the upper edge bent portion (7) of the metal inner skin material (2) so as not to come into contact with each other. The lower edge (14) and the lower edge bent portion (10) of the metal endothelial material (2) are also prevented from coming into contact with each other. Thus, the metal endothelial material (2)
If the outer skin material (3) is kept out of contact with the outer skin material (3), the heat of the roofing shingle (15) heated in direct sunlight will be conducted from the outer skin material (3) to the metal inner skin material (2). It can cut off the heat insulation effect.

The heat insulating base material for roof (1) thus constructed is laid on a rafter (5) which is a part of the base as shown in FIG. The protrusions (6) and the recesses (8) of the heat insulating base material for the roof (1) (1) fit together and the bottom surfaces (11) and (11) are along the rafters (5). And looks like a ceiling board. For this reason, it can be utilized as a heat insulating base material for a roof which also serves as a ceiling plate.

In addition, since the portion where the convex portion (6) and the concave portion (8) are fitted is bent in a hook shape, even if a fire occurs, the flame can be prevented from being transmitted to the roof plate to some extent. .
As shown in FIG. 4, if the number of combinations of the convex portions (6) and the concave portions (8) is large, the flame can be further prevented.

Since the metal endothelial material is harder than the wood wool board, there is also an advantage that the interval of the 490 mm pitch barp can be widened to 600 mm pitch, and the number of barps can be reduced.

When roofing is performed using this heat insulating base material for roof,
The method shown in the figure is used.

This mounting bracket (16) is a heat insulating base material for roof (1)
Attach the fixing surface (16a) for fixing to the tree (5) with a fastener such as a pilot hole unnecessary screw (18), a standing surface (16b) that stands up therefrom, and a suspension element (17). Mounting surface (16c). In addition, fixed surface (16
The end of a) is raised almost at a right angle and is a standing piece (16d). The above-mentioned pilot hole unnecessary screw is a screw that can perform three steps of drilling, tapping, and fastening in a single step.

When actually roofing the roof, first place the heat insulating base material for roof (1) on a rafter (5) which is a part of the base, and at the ridge side portion of the heat insulating base material for roof, and The mounting bracket (16) is placed on the portion covered by the heat insulating base material for roof, and is fixed to the barbecue (5) together with the heat insulating base material for roof (1) with fastening tools such as pilot holes unnecessary screws (18). By repeating this method, the heat insulating base material for roof (1) is laid on the entire surface of the roof. At this time, the embodiment shown in FIG.
In order to prevent the head from contacting the metal inner skin material (2) of the heat insulating base material for roof (1) that comes on the upper stage, the pilot hole unnecessary screw (18) and the metal inner skin material (2) The size is set so that there is an interval between them. By doing so, it is possible to block the heat of the roof slab from being conducted to the metal inner skin material (2) via the mounting bracket (16).

When fixing the mounting bracket (16), the upright piece (16d) rising substantially at a right angle is aligned with the upright portion (13) of the outer cover material (3). 15) Can be easily installed in parallel with.

Next, the horizontal roofing slab (15) is roofed while the suspension element (17) is fixed to the mounting surface (16c) of the mounting bracket (16) with a fastener such as a pilot hole unnecessary screw (18).

Because the roof insulation base material (1) and the roof structure using the same have such a configuration, even if it takes time for the designer to decide the color of the roof slab, the roof insulation base material (1) There is an advantage that no special curing is required even if the entire roof is laid. Roof insulation base material (1)
In addition to the structure in which the mounting bracket (16) is fastened with a pilot hole unnecessary screw (18) on the part of the ridge side where the roof insulation base material of the upper tier is covered, the roof insulation base material (1) Since the outer skin material (3) has a waterproof property, the outer material (3) plays a role of a waterproof sheet, so that curing for rainy weather is not required,
The upper and lower insulating roofing base materials (1) have a convex portion (6) projecting in the lateral direction and a concave portion (8) opening in the lateral direction.
Are fitted and connected to each other, so that there is no fear that the heat insulating base material for roof (1) will fly when the wind blows without special curing.

And, since the combination of the suspender (17) and the mounting bracket (16) is used, the roof insulation base material (1) is laid down while being fixed using the mounting bracket (16).
When roofing the roof, the horizontal roofing shingle (15) can be laid while the hanging element (17) is fixed to the mounting surface (16c) of the mounting bracket (16). There is an advantage that it is easy.

〔The invention's effect〕

The heat insulating base material for roof according to the present invention and the roof structure using the same have the following effects.

First, the insulation base material for the roof is described. The cross-sectional shape of the roof insulation base material when cut in the eaves ridge direction is approximately sloped so that the bottom surface of the roof insulation material is along the base such as a tree. The thickness of the heat insulating base material for the roof increases from the ridge side edge to the eaves side edge, and the unevenness of the adjacent roof heat insulating base material fits into the roof. The bottom of the thermal insulation base material looks like a ceiling plate. For this reason, it can be utilized as a heat insulating base material for a roof which also serves as a ceiling plate.

In addition, if the construction is performed using the heat insulating base material for a roof, a roof having heat insulation properties can be constructed without using the conventional method of laying a double wooden wool board or providing an air layer. be able to.

In addition, even when it takes time for the designer to determine the color of the shingle, there is an advantage that no special curing is required even if the heat insulating base material for the roof is laid all over the roof. In other words, on the ridge side of the thermal insulation base material for the roof, and
In addition to the structure in which the part covered by the heat insulating base material for the upper tier is covered with fasteners, the outer skin material of the heat insulating base material for the roof serves as a waterproof sheet because it is waterproof. There is no need for curing in case of rain. In addition, the upper and lower tier roof insulation base materials are connected by connecting the concave and convex parts that are formed by opening or projecting laterally on the ridge side and eave side edges. Therefore, when the wind blows without special curing, it is possible to stop the roof insulation base material on the ridge side of the roof and the upper part of the roof insulation base material with the fasteners. This is because there is no fear that the heat insulating base material for the roof will fly.

In this way, even before the design of the roof shingle is decided, the thermal insulation base material for the roof can be laid without the need for special curing, so that the indoor construction work can be advanced afterwards. Is also solved.

In addition, since a combination of a hanger and a mounting bracket is used, the roofing insulation material is fixed using the mounting bracket and laid down, and then when the roof is roofed, the hanger is fixed to the mounting surface of the mounting bracket. However, since it is only necessary to roof the roofing shingles, there is an advantage that the work of attaching the roofing shingles is easy.
