Description

DETAILED DESCRIPTION OF THE INVENTION The present invention improves the heat insulation properties of the roof itself by eliminating voids that occur at the joints of roofing materials in a roof structure, particularly in a terraced roof structure. is deformed,
or relating to roof structures that were prevented from being destroyed.

Conventional terraced roofs had a structure as shown in Figure 1. That is, laying the field board 2 on the rafters 1,
Secure this with 3 nails.

Roofing 41, for example, asphalt felt, is successively laid on top of this to form a base 5, and on top of that, roofing material 6 as shown in FIGS. 2(a) to 15 is suspended. //.As a result, a wedge-shaped gap A is formed between the roofing 4 and the roofing material 6.
very often left. Moreover, this deformation had the disadvantage of impairing the roof's main function of waterproofing◇
Furthermore, deformation of the roofing material 6 may cause cracks in the coating film,
Since the roof surface is exposed, the weather resistance and corrosion resistance of the roofing material are significantly reduced. In other words, roofing material 6
They were exposed to harsh temperatures ranging from high temperatures (60-80C in mid-summer) to 20C in the bitter cold, and had the disadvantage that even the slightest damage caused rapid deterioration. In addition, the roofing material 6 is
Since the outside air comes into contact with both the back and the front surface, dew condensation occurs, which has the disadvantage of corroding the base.

In order to eliminate such drawbacks, the present invention provides a heat insulating spacer with a cross-sectional shape that fills the gap formed between the roofing material and the base material, thereby preventing the roofing material from deforming or coming off. This project proposes a roof structure that prevents condensation.

EMBODIMENT OF THE INVENTION Below, the roof structure based on this invention is demonstrated in detail using drawing. Note that parts corresponding to those in FIG. 1 are given the same symbols and numbers.

Figures 3(a) to (C1 are perspective views showing one embodiment of the above roof structure; in the figures, 1 is a rafter, 2 is a shedding board, 3 is a nail, 4 is a roofing (waterproof paper), and 5 is a perspective view showing an embodiment of the roof structure. The base, 6 is a roofing material, and 7 is a heat insulating spacer, which is formed to have the same cross-sectional shape as the gap A shown in FIG. The heat insulating spacer 7 has a structure in which the heat insulating core material 8 is a single unit, as shown in FIGS. 4(a) to 4(c), for example. As shown in d), the surface material 9 is attached to one side of the heat insulating core material 8, and the structure shown in FIG.
) ~ (ω is a structure in which the backing material 10 is also attached, especially (n, (ω is a heat insulating structure) having a polymeric piece 11 protruding outward from at least one end edge of the core material 8. Further, specifically, the heat insulating core material 8 is made of polyurethane foam, polyethylene foam, polystyrene foam, and highly heat-resistant polyisocyanurate foam or phenol foam that becomes a carbonized layer under high heat. It is made of seeds and has a closed cell foam structure with a density of about 40 to 100 cells.It is also preferable that the compressive strength is 30L- or more.This can withstand snowfall of 300kllArt. In the case of this heat insulating spacer 7, since the roofing board is installed, no bending force is applied, and it is sufficient to have the required compressive strength and appropriate elasticity. The surface material 9 and the back material 10 include kraft paper, asbestos paper, nonwoven fabric, gypsum paper, lead foil, aluminum foil,
It is a sheet-like product made by laminating one or more of Terfelt, asphalt felt, synthetic resin film, etc. Note that it is desirable to avoid using a synthetic resin film, which has poor heat resistance, as the surface material 9. moreover,
To explain specifically, Fig.
This is a roof structure in which a heat insulating spacer 7 as shown in Fig. 4(b) is used between the base 5 made of asphalt roofing and the roof material 6 as shown in Fig. 4(b). Figure (0) shows a roof structure in which a heat insulating spacer 7 shown in FIG. 4 [f] is interposed between a base 5 made of asphalt roofing 4 and a roof material 6.

Next, to briefly explain the construction method, as shown in FIG. 3(a), first, heat insulating spacers 7-1 are laid on the roofing board 2, and the appropriate locations are temporarily fixed with nails or the like. Next, the roofing material 6-1 is laminated on top of the roofing material 6-1.
A is attached with a partial hanger 11, and the partial hanger 11 is fixed to the roof board 2 with nails 3. Next, the heat insulating spacer 7-2 is laid as shown in the figure, and then the upper edge 7a of the eave direction end of the roofing material 6-2 is engaged with the lower edge of the roofing material 6-1, and the layers are laminated. . The roof can be constructed by performing these operations sequentially from the eaves to the ridge.

What has been described above is only one embodiment of the roof structure according to the present invention, in which activated carbon is used as the heat insulating core material 8.

It is also possible to add a moisture absorbent such as silica gel or theolite, or apply it to the surface material 9 and adhere it.0Also, it is also possible to form the heat insulating spacer 7 with a hard body or a hollow body and use it mainly for reinforcement. .

As mentioned above, the roof structure according to the present invention can sufficiently withstand the load applied to the space between the roofing material and the base material, and also has a heat insulating spacer that has heat insulating properties.
This feature prevents the roof material from deforming or separating the connecting parts, and the roof has enhanced weather resistance, corrosion resistance, and waterproofness. Furthermore, since the heat resistance effectively acts on the back of the roofing material, there is almost no occurrence of dew condensation, it is easy to install, and it also has the advantage of being highly insect repellent. Furthermore, when aluminum foil or lead foil is used for the front and back materials, it has excellent heat radiation and sound insulation properties. In addition, particularly regarding waterproofness, when the backing material 10 has a protruding overlapping part, it also has a secondary waterproofing feature.
