Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a step-like waterproof, heat-insulating layer with waterproof, heat-insulating, and moisture-controlling properties between the rim of a building or structure, rafters, and exterior materials. This relates to an exterior structure that is covered with exterior materials.

An embodiment of the exterior structure according to the present invention will be described in detail below with reference to the drawings. Figure 1 a, b
1 is a partially cutaway perspective view and a vertical sectional view showing the case where the exterior structure according to the present invention is applied to a roof. In the figure, 1 is the frame, which consists of a frame, rafters, main columns, studs, etc., and 2 is an exterior material, such as a roof material, for example, a second
It has a cross-sectional shape as shown in Figures a to f, has a rectangular outer shape, and has a stepped roofing structure. In addition, the height h is the waterproof insulation layer 3 below.
The projections 4a and 5a of the sheathing insulation boards 4 and 5 (hereinafter simply referred to as board 4 or board 5) as shown in FIGS. It is set to be approximately the same as the height H. To explain further, as shown in FIGS. 4a and 4b, the heat insulating layer 3 is formed by arranging a large number of boards 5 in series with their short side end surfaces in contact with each other to form the first stage 3-n ₁ of the heat insulating layer 3. , then the second tier 3-n ₂ , the third tier 3-n ₃ ...The roofing is done in a stair-like manner from the bottom (eave in the figure) to the top (ridge) until the nth tier 3-n _o . This is what I did. That is, the first stage 3-n ₁ of the heat insulating layer 3 is a board 5, so-called 5-n 1 _-1 , 5-n ₁ -, which is called for convenience in the digit direction as shown in Figure a.
2, 5-n ₁ -3, 5-n ₁ -4,...5-n ₁ -n are arranged in series with the end surfaces of the short sides of the rectangle in contact with each other, and the protrusion on the upper end 5a is fixed with nails 6. Next, the second stage 3-n ₂ of the heat insulating layer 3 is called 4-n ₁ -1, 4-n ₁ - for convenience as shown in figure b.
A board 4 consisting of 2, 4-n ₁ -3, . . . 4-n ₁ -n is fixed in series. Thereafter, the third stage, the fourth stage, ... the nth stage are laid in the above order, and the lower end surface in the longitudinal direction of the upper row is brought into contact with the upper end surface in the longitudinal direction of the lower row. was formed.
The difference between the boards 4 and 5 described above is that there is a protrusion 4a (having a step and reinforcing function) at each end of both long sides, or a protrusion 5 is present only at one end of the long side.
a exists, and the board 5 is used only in the first stage of the exterior structure. In addition, as a specific example of boards 4 and 5, L=200~
3636mm, W=150~600mm, thickness t=10~40mm, H
= 5 to 20 mm, Δt = 9 to 15 mm, and ΔW = 5 to 20 mm. Moreover, these boards 4 and 5 are made by impregnating and coating approximately 10 to 40% asphalt (weight ratio) to the wood fiberboard in order to effectively exhibit heat insulation, sound absorption, and moisture control properties, and to reduce weight. It is.

Next, construction of an exterior structure, such as a roof, will be explained.

First, the first stage 3- _n1 of the heat insulating layer 3 is constructed on the frame (rafter) 1 as described above. Next, the second stage 3- _n2 of the heat insulating layer 3 is formed as shown in FIG. 4b. In this case, the nail 6 may be a screw nail or a general nail, but a zinc nail is preferable. Therefore, the exterior material 2 as shown in FIG.
(roofing material) board on the first stage 3-n ₁ , 5-n ₁
-1, 5-n ₁ -2, 5-n ₁ -3,... Although not shown, the first stage is placed on 5-n ₁ -n, and the The exterior part (roof part) 2- _n1 is roofed. In other words, exterior material 2 (roofing material) 2-n ₁ − is referred to as exterior material 2 (roofing material) for convenience.
1, 2-n ₁ -2, 2-n ₁ -3, . . . 2-n ₁ -n are laid and engaged in this order. In addition, the second stage exterior part (roof part) 2-n ₂ is exterior material 2 (roofing material)
2-n ₂ -1,2-n ₂ - called as above
2, 2-n ₂ -3,...The lower end of 2-n ₂ -n (not shown) is connected to the first stage exterior material 2 (roofing material) 2-n ₁ -
1, 2-n ₁ -2, ... 2-n ₁ -n, and the upper end is connected to the board 4-n ₁ - through the locking tool 7.
1, 4-n ₁ -2, 4-n ₁ -3, ... fixed on 4-n ₁ -n. Therefore, in order to cover the entire base with an exterior structure (roof), it is sufficient to repeat the steps described above sequentially from the bottom end to the top end.

What has been described above is only one embodiment of the exterior structure according to the present invention, and it is also possible to form the heat insulating layer 3 on the exterior wall in order starting from the base, and then apply the exterior material 2 in a stepped manner. It is something. Furthermore, Fig. 5a,
As shown in b, a piece of waterproof paper 8 for joint covering is pasted on the protrusion 4a of the board 4, and the board 4 has a structure that is used as shown by the two-dot chain line during use.
As shown by the dashed line in Fig. a, a thermal radiation film 9 with or without micropores may be attached to form a board 4 with a balance between heat insulation and humidity control.
Furthermore, as shown in Figure b, a waterproof sheet 10 is attached to the board 4 to add sound absorption and to strengthen the strength.
It is also possible to do this. Moreover, it is also possible to use caulking material between the boards 4.

As described above, according to the exterior structure according to the present invention, the cost is reduced because the board can be directly installed on the frame without using a base board such as a roof board. Since the end surfaces of the boards are brought into contact with each other, the asphalt impregnated in the boards is softened by heat (sunlight) and adheres closely to each other, forming a single waterproof layer with no gaps. The insulation layer can use the protrusions of the N-shaped cross-section board as a step, so
It functions as a ruler when installing the exterior material, and since the board is a unit, it is easy to install the exterior material. Since the exterior material is placed and fixed on the heat insulating layer, it can sufficiently withstand external forces.
Since the exterior material is roofed in a stepped manner, a three-dimensional exterior can be formed with high efficiency and without the need for skill. It has the following characteristics.
