Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides for extremely easily forming a waterproof, heat-insulating layer having waterproof, heat-insulating, and moisture-controlling properties in a stepped roof between the foundation and exterior materials of buildings and structures, and The present invention relates to an exterior construction method in which the exterior material is reinforced with the above-mentioned waterproof and heat insulating layer to form a stepped roof with high efficiency and a three-dimensional appearance.

An embodiment of the exterior construction method according to the present invention will be described in detail below with reference to the drawings. FIGS. 1fa) and 1(b) are a partially cutaway perspective view and a vertical cross-sectional view showing the case where the construction method according to the present invention is applied to a roof. In the figure, 1 is a rafter, 2 is a roof board, 3 is a nail, and 5 is a roofing material, which has the cross-sectional shape shown in Figures 2 (-) to (g), and has a stepped roofing structure, and its height. 3(a) and fb), which are constituent members of the waterproof heat insulating layer 6 (hereinafter simply called the heat insulating layer), are the protrusions of the waterproof base plates 7 and 8 (hereinafter simply referred to as boards) as shown in FIGS. The height H is set to be approximately the same as the height H of the portions 7a and 8a. Note that the only difference in the waterproof base plate 7.8 is whether 7a is present on both long sides, or whether a protrusion 8a is present only on one end of the long side. Further, the waterproof base plate 7.8 has a rectangular outer shape, for example, L-200 to 3636 mm, W = 150 to 60 mm.

+1! , Δt=about 5 to 15 degrees, and ΔW=about 5 to 20 degrees, and are made of soft fiberboard or the like, which is a board impregnated or coated with asphalt. In particular, the vertical cross section of this waterproof base board 7 is approximately N-shaped, making it possible to construct the heat insulating layer 6 extremely easily and without requiring any skill. A void 9 is formed between the back surfaces 7b to effectively utilize the heat insulation, sound absorption, and humidity control properties of the waterproof base plate 7, and to reduce weight and improve strength. In addition, the asphalt coating and impregnation amount are as follows for the waterproof base plate 7 in relation to the above performance.
It is about 10 to 40% (weight ratio).

Furthermore, the heat insulating layer 6 is a waterproof heat insulating part 6-n1.

Next, the construction method for the above roof will be explained.

In Fig. 1(a), first, the entire surface of the field board 2 is covered with Fig. 4(a).

What has been described above is an example of the exterior construction method according to the present invention, and it is also possible to form the heat insulating layer 6 on the exterior wall in order from the upper base, and then to roof the exterior wall material in a stepped manner. It is something. Furthermore, as shown in FIG.
A piece of waterproof paper 11 for joint covering is pasted on the protrusion 7a of the board, and a board with a structure to be used as shown by the two-dot chain line during use can be made, or a board with micro-holes as shown by the one-dot chain line in the figure (a) can be used. Alternatively, a non-porous heat radiating film 12 may be attached to create a board that balances heat insulation and humidity control properties.

Furthermore, as shown in Figure (b), a waterproof sheet 13 can be attached to the board to add sound absorbing properties and to strengthen the board. Although not shown, it is also possible to form the above-mentioned structure by combining plywood and asphalt roofing.

Furthermore, the heat insulating layer 6 can also be formed of a synthetic resin foam with a closed cell structure having a certain degree of strength (practical). At this time, inorganic fibers and inorganic aggregates are contained in the synthetic resin foam, and the material is formed to have a compressive strength of 300 to .beta.. In addition, the synthetic resin foam itself is waterproof,
It has corrosion resistance, and it is also possible to add a well-known fire retardant (borax, sodium metaborate, perlite grains, etc.) to improve fire resistance.

As mentioned above, according to the exterior construction method according to the present invention, it is possible to reliably and easily form a heat insulating layer having heat insulating properties, waterproof properties, and moisture control properties between the roof board and the exterior material; It can prevent corrosion of roof boards and exterior materials due to dew condensation, etc. ■A gap with a triangular vertical cross section is formed between the heat insulating layer and the base for each waterproof and insulating part, effectively enhancing the moisture control function of the insulating layer. ■The heat insulating layer uses the protrusions of the constituent boards, which have an almost N-shaped cross section, as steps, so it functions as a ruler when installing the exterior material, and since the boards are unitized, it is easy to install the exterior material. becomes. ■Since the exterior material is placed and fixed on the heat insulating layer, it can withstand external forces sufficiently. ■Since the exterior material is constructed in a stepped manner, a three-dimensional exterior can be created with high efficiency and without the need for skill. It has the following characteristics.
