る。 An embodiment of the exterior structure according to the present invention will be described in detail below with reference to the drawings. That is, FIGS. 1a and 1b are a partially cutaway perspective view and a vertical cross-sectional view showing an example of an exterior structure according to the present invention, for example, a roof. In the figure, 1 is the main body, 2
3 is a base board, 3 is a nail, 4 is a waterproof sheet, 5 is a base, and the waterproof sheet 4 is laid on the base board 2. Reference numeral 6 denotes the exterior material, which has a cross-sectional shape as shown in Fig. 2 a to j, giving the appearance of a stepped roof, and its height (step) h corresponds to the thickness of the waterproof and heat insulating layer 7 described below. be. In addition, among the exterior materials 6, those shown in FIGS. 2 a to e and i and j do not have hangers, and those shown in f to h are fixed via hangers 9 as shown in FIGS. 3 a to d, for example. It is something. Waterproof insulation layer 7 (hereinafter referred to as
The heat insulating layer) is formed by a rectangular sheathing insulation board (hereinafter simply referred to as a board) 8 and a reinforcing square member 10 from the bottom to the top, or from the eave to the ridge as shown in the figure.
are arranged so that the upper and lower end surfaces of the boards 8 are in contact with each other, and a space 11 having a triangular longitudinal section is formed between the back surface of each board 8 and the base 5, and a part of this space 11, especially a part with a large gap, is reinforced. After interposing the square timbers 10, the protrusions 8a of the board 8 are fixed to the base 5 with nails 3, so that the external appearance is shaped like a plurality of steps. To explain further, the heat insulating layer 7 is constructed using a board 8 as shown in FIG. 4 and reinforcing square members 10 as shown in FIGS. It is something. That is, in the first stage 7- n1 of the heat insulating layer 7, a board 8 as shown in FIG. protrusion 8 formed on
Place the base 5 so that a is located above (in the direction of the ridge)
Boards 8-n 1-1 , 8-n 1-2 , 8-n 1-3 on top
... 8-n 1 -n in the order of digits, the short side end faces of each board are arranged in series in contact with each other, and the boards are fixed to the base 5 via the nails 3. In addition, in the second stage 7-n 2 , the reinforcing square material 10 is brought into contact with the long side end surface of the protrusion 8a of the board 8, and the long side end surface of the reinforcing square material 10 is brought into contact with the 10
-n 1 -1, 10-n 1 -2, 10-n 1 -3...10-
Lay the board 8 in the order of n 1 - n, and then lay the board 8 on the reinforcing square timber 10-n 1 in the same way as the first stage.
1, 8-n 2 -2 , 8-n 2 -3, . Note that the thickness t of the protrusion 8a is the same as that of the board 8.
If the thickness of is Δt, t=10~40mm, Δt=5~15
mm, the dimension is t-Δt=T, and the connecting portions between each plate of the heat insulating layer 7 are flush. Therefore, in order to form the heat insulating layer 7 on the base, such construction can be carried out from the eaves to the ridge. In addition, considering the step H (board thickness) of the heat insulating layer 7, the board 8 has a thickness t of 10 to 40 mm, a rectangular outer shape, a width W of about 150 to 600 mm, and a length L of 200 to 40 mm. It was set at around 3636mm. This was selected because of the strength, the fact that there are steps with dimensions that give the appearance of a stepped roof, and the general dimensions of the exterior material 6, such as roofing material. Furthermore, since the board 8 functions as a waterproofing material, a heat insulating material, a reinforcing material, and a humidity control material, it is made of a wood fiber board impregnated or coated with asphalt, or a mixture of asphalt powder and refined fibers. It consists of a heated and pressurized plate. In particular, the amount of asphalt impregnated or coated is 10 to 40% (weight ratio) in consideration of waterproofness and humidity control properties. The reason why the amount of asphalt impregnated is specified as above is because if it is less than 10%, it lacks waterproofness, and if it is more than 40%, the humidity control property, so-called breathability, is significantly reduced. Further, the reinforcing square bar 10 is attached to a part of the space, particularly a large gap part, in a space 11 having a triangular longitudinal section formed between the back surface of the base 5 and the back surface of the board 8.
It is preferable to dispose the board 8 so that the long side end (lower end) opposite to the protrusion 8a is placed on the reinforcing square material 10, and the surface of the protrusion 8a and the upper It has a spacer function so that it is flush with the lower end surface of the board 8 located at.
The material is a rod-shaped body made of wood, hollow pipe, sheathing insulation board, etc.

be fixed to the eaves. Next, as shown in FIG .
-n 1 -2, 8-n 2 -3...8-n 1 -n, and the projections 8a are fixed with nails 3. Next, in order to construct the second stage of heat insulation layer 7-n 2 , reinforcing square timbers 10
As shown in Figure 6b, 10-n 1 -1, 10-n 1
-2, 10-n 1 -3...10-n 1 -n, the board 8-n 2 - comes into contact with the side surface of the projection 8a, and then the board 8-n 2 -
1, 8-n 2 -2, 8-n 2 -3...8-n 2 -n are laid in series along the girder direction, and the protrusion 8a
are fixed with nails 3 to form the second stage. Therefore, in order to form the heat insulating layer 7 over the entire base 5, it is sufficient to carry out the construction as described above sequentially from the eaves to the ridge. Next, an exterior material 6 , for example, the roofing material 6 shown in FIG . Fix it. By sequentially engaging or placing the left end of the so-called roofing material 6 (named for convenience) 6-n 1 -1 on the right edge of the roofing material 6-n 1 -2 in the girder direction, the first stage is completed. A first stage roof is laid on the second boards 8-n 1 -1, . . . 8-n 1 -n. Further, in the second stage, similarly, the lower ends of the roofing materials 6-n 2 -1, 6-n 2 -2, ... 6-n 2 -n are engaged with the upper ends of the roofing materials of the first stage, The boards 8-n 2 -1, 8-n 2 -2, ...8-n 2 -n are placed in order, engaged, etc., and fixed via the hanger 9 to roof the second stage. to be accomplished. Therefore, for the roof, the same work as above was carried out from the 3rd stage to the nth stage, so-called.
This process is completed by repeating the process until the entire heat insulating layer 7 is covered.

形成できる。等の特徴がある。 As described above, according to the exterior structure according to the present invention, a base consisting of a base plate and a waterproof sheet is formed on the frame, and it is possible to prevent condensation and leakage of rainwater from reaching the frame. A heat insulating layer that has a certain degree of rigidity and bending strength, as well as heat insulation, waterproofness, and humidity control properties is formed on the base to prevent condensation and to prevent corrosion of the base plate and exterior materials. . The insulation layer functions as a backup material for the exterior material. By interposing a bar-shaped square material in the triangular space formed between the base and the heat insulating layer, it is possible to reinforce the mechanical strength of the board, reduce the weight of the board, and fully demonstrate the functions of the board. Since the heat insulating layer is formed in a step-like manner with steps in the thickness of the boards that make up the structure, it functions as a ruler when installing the exterior material, making it easier 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.
