The exterior structure such as exterior walls and roofs that have been used in the past has the configuration shown in Figure 1. That is, for example, on a roof, a field board 2 is laid on rafters 1, this is fixed with nails 3, and asphalt 4 is laid on the base 5, which is impregnated with asphalt.
Alternatively, a coated soft fiberboard 6, so-called sheathing insulation board, is sequentially laid in a stepwise and horizontally patterned manner to form a waterproof and heat insulating layer 7, and on top of that, for example, as shown in FIGS. 2a to 2h, The structure was such that roofing materials 8 such as these were sequentially fixed via hangers 9. In this structure, the base 5 and the soft fiberboard 6 are
A void 10 with a triangular cross section was always formed between the back surfaces of the . As a result, a large amount of snow falls on the roof, and the hollow portion 10 of the soft fiberboard 6 is deformed due to the load of people working on the roof.
There was a drawback that the roofing material 8 was deformed due to breakage, and the connecting portions thereof were separated. In addition, the roofing material 8 vibrates due to rainwater and falling snow from the second floor, which is propagated to the waterproof and heat insulating layer 7, resulting in even louder rain noise and vibrations that can be heard on the ceiling.

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. 3a and 3b are a perspective view and a vertical sectional view showing a partially cut away roof of the above structure. In addition, the first
Parts corresponding to those in the figures are given the same symbols and numbers. In the figure, 1 is a rafter, 2 is a sheathing board, 3 is a nail, 4 is a roofing (waterproof layer), and 5 is a base, which is either a sheathing board 2 alone or a structure in which roofing 4 is laid on the shedding board 2. It is what it is. 6 is a soft fiberboard, and 7 is a soft fiberboard impregnated with or coated with multiple pieces of asphalt with a waterproof heat insulating layer (hereinafter referred to as a heat insulating layer at the end), a so-called sheathing insulation board (hereinafter simply referred to as a board).
6 are fixed with nails 3 so that the upper and lower ends of each board overlap each other as they move from the eaves to the ridge, and a space 10 with a triangular vertical cross section is formed between the back surface 6a of each board and the base 5. However, the exterior is structured in the form of multiple steps. To explain further, the heat insulating layer 7
A board 6 as shown in the figure is laid and fixed as shown in FIG. That is, the first stage 7-n 0 of the heat insulating layer 7 is the board 6-n 0 -1, 6-n 0 -2,
...Constructed in series (horizontally) with the left and right ends touching in the order of 6-n 0 -n. Also, the second stage 7-n 1 is the board 6-n 1 -1, 6-n 1 -2, ...6-n 1 -n
In the same manner as above in the direction of arrow A, the lower end is overlapped by Δl, and the nail 3 is inserted from above.
A hole 10 having a triangular vertical cross section is formed by driving the hole 10 into the hole and bringing the upper end into contact with the base. This structure is formed in n stages up to the ridge in the direction of arrow B. It should be noted that the air filter 10 functions as an adjustment section for promoting the humidity control function of the board 6. In addition, the board 6 is formed to have a thickness of 3 to 30 mm and a rectangular outer shape, taking into consideration the step h (board thickness) of the heat insulating layer 7.
Its width W is approximately 150 to 600 mm, and length L is 200 to 3636 mm.
It is set at This was chosen because of its strength, the fact that there are steps that give the appearance of a stepped roof, and the general dimensions of roofing materials. Furthermore, in order to function as a waterproofing material, a reinforcing material, and a humidity control material, the board 6 is made of high-quality wood raw wood that is pulped, and is further treated with fibrillated materials, insulation materials, refined fibers, waterproofing agents, preservatives, insect repellents, etc. It is made from asphalt, etc. Moreover, the board 6 is formed by forming a board from this raw material, and also by coating the surface with asphalt, impregnating it with asphalt before forming it into a board, or using asphalt powder and refined fibers. This is a sheathing insulation board consisting of one plate that has been mixed, heated, and pressed. In particular, the amount of asphalt impregnated or coated is 10 to 40% (weight ratio) in consideration of water release properties and humidity control properties. In addition, the amount of asphalt impregnated is specified as above; if it is less than 10%, it will lack waterproofness, and if it is less than 10%, it will not be waterproof.
This is due to the fact that the humidity control property, so-called breathability, is significantly reduced. 8 is the roofing material shown in Figure 2a.
The cross-sectional shape shown in ~h gives a stepped roof appearance, and the height (step) h corresponds to the thickness of the waterproof and heat insulating layer described below. Reference numeral 11 denotes posts having a shape as shown in FIG. 6, for example, and are dotted in the space 10 between the base 5 and the back surface 6a of the board as shown by dotted lines in FIG. be. That is, the post 11 is made of a highly viscous inorganic material in the form of a dumpling on the base 5.
By placing the board 6 on top of the board 6, it is pressed into a deformed trapezoidal cross section as shown in FIG. 5 and the board 6 are bonded together to add vibration-proofing properties to the board 6 and to serve as a reinforcement material for compression resistance. Its composition is
It is a cement-based, gypsum-based, or clay-based material mixed with synthetic resin components.
