Description

[Detailed Description of the Invention] The present invention provides a waterproof, heat-insulating layer with waterproof, heat-insulating, and moisture-controlling properties between the frame and exterior material of a building or structure by laying a large number of sheathing insulation boards in a stepped manner. The present invention relates to an exterior structure in which a reinforcing square member is interposed below a space having a triangular cross section formed between a building frame and the above-mentioned waterproof and heat insulating layer, and is laterally roofed.

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 the nail, and 3 is the exterior material, which has a cross-sectional shape as shown in Figure 2 a to j, giving the appearance of a stepped roof, and its height (step) h corresponds to the thickness of the waterproof insulation layer 4 described below. It is something to do. In addition, of the exterior material 3, the second
Figures a to e, i, and j are shown without a hanger, while figures f to h are fixed via a hanger 6 as shown in Figures 3 a to d. The waterproof insulation layer 4 (hereinafter simply referred to as the insulation layer) is formed from the bottom to the top, or from the eave to the ridge as shown in the figure, through a rectangular sheathing insulation board (hereinafter simply referred to as the board) 5 and a reinforcing square member 7. The upper and lower end surfaces of each board 5 are in contact with each other when facing the board 5 , and a space 8 having a triangular vertical cross section is formed between the back surface of each board 5 and the body 1 . After interposing reinforcing square members 7 in areas with large gaps, the protrusions 5a provided at the long side ends, which are the upper ends of the L-shaped vertical cross-section boards 5, are fixed to the frame 1 with nails 2, giving the appearance a multi-tiered appearance. It is structured in a stair-like manner. To explain further, the heat insulating layer 4 is constructed by using a board 5 as shown in FIG. 4 and reinforcing square members 7 as shown in FIGS. It is something. That is, the first stage 4- _n1 of the heat insulating layer 4 is a board 5 as shown in FIG. The board 5-n ₁ - is placed on the frame 1 so that the protrusion 5a at the upper end is located upward (in the direction of the ridge).
1, 5-n ₁ -2, 5-n ₁ -3...5-n ₁ -n, the short side end surfaces of each board 5 are brought into contact with each other and arranged in series in the direction of the girder, and fixed via nails 2. It was formed by In addition, in the second stage 5-n ₂ , as shown in FIGS. 6b and 6c, the reinforcing square bar 7 is brought into contact with the longitudinal side end surface of the protrusion 5a of the board 5, and the long side end face of the reinforcing square bar 7 is 7−n ₁ − in the digit direction by touching
1, 7-n ₁ -2, 7-n ₁ -3...7-n ₁ -n, and then lay the board 5 on the reinforcing square material 7-n ₁ in the same way as the first stage. n ₂ −1, 5−n ₂ −2,
...5-n ₂ -n, and the projections 5a are fixed to the frame 1 with nails 2. Note that the protrusion 5a
The thickness t of the board 5 is t=10, where the thickness of the board 5 is Δt.
~40 mm, Δt = 5 to 15 mm, and the dimensions are t - Δt = T, and the connecting portions between each plate of the heat insulating layer 4 are preferably made substantially flush. Therefore, in order to form the heat insulating layer 4 on the building frame, such construction may be performed from the eaves to the ridge. In addition, the board 5 has a thickness t of 10 to 40, taking into account the step H (board thickness) of the heat insulating layer 4.
mm, the outer shape is rectangular, and the width W is approximately 150 mm.
~600mm, and the length L is set to approximately 200~3636mm. 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 3, such as roofing material. Furthermore, since the board 5 functions as a waterproofing material, a heat insulating material, a reinforcing material, and a humidity control material, it is made of a wood fiberboard impregnated or coated with asphalt, or a mixture of asphalt powder and refined fibers. It consists of a plate that has been heated and pressurized. In particular, the amount of asphalt impregnated or coated is 10 to 40% (weight ratio) in consideration of waterproofness and humidity control properties. The amount of asphalt impregnated is specified as above; if it is less than 10%, it lacks waterproofness, and if it is more than 40%, it has moisture control properties, so-called.
This is due to a significant decrease in breathability. Furthermore, the reinforcing square material 7 is provided with respect to the space 8 having a triangular longitudinal section formed between the back surface of the frame 1 and the board 5.
The board 5 is placed in contact with the side surface of the protrusion 5a only in a part of the space, especially the large gap, and the long side end (lower end) opposite to the protrusion 5a of the board 5 is placed on the protrusion 5a. It has a spacer function so that the surface of the board 5 and the lower end surface of the upper board 5 are flush with each other, for example. The material is a rod-shaped body made of wood, hollow pipe, sheathing insulation board, etc.

Next, a construction example of the above-mentioned exterior structure, such as a roof structure, will be briefly explained. In FIG. 1a, first, a fascia is fixed to one end of the frame, and then a wide and small dancer 9 is fixed to the eaves. Next, as shown in FIG. 6a, the heat insulating layer 4
The first stage 4-n ₁ is board 5-n ₁ -1, 5-n ₁ -
2, 5-n ₂ -3...5-n ₁ -n, and the projections 5a are fixed with nails 2. Next, in order to construct the second stage heat insulating layer 4-n ₂ , the reinforcing square members 7 are arranged as 7-n ₁ -1, 7-n 1 -2, ₇ -n ₁ as shown in FIG. 6b.
-3...7-n ₁ -n, the boards 5-n 2 -1, 5-n 2 - come into contact with the long side end surface of the projection 5a, and then the boards 5-n _{2 -1} , 5-n ₂ -
2, 5-n ₂ -3...5-n ₂ -n are laid in series along the girder direction, and the projections 5a are fixed with nails 2 to form a second stage. Therefore, in order to form the heat insulating layer 4 over the entire frame 1, it is sufficient to carry out the construction as described above sequentially from the eaves to the ridge. Next, the exterior material 3, for example the roofing material shown in _{FIG .} do. Roofing material 3 (named for convenience) The left end of so-called 3-n ₁ -1 is roofing material 3-n ₁
By sequentially engaging or placing the board 5-2 on the right edge of the board 5-2 in the digit direction,
The first stage roof is laid over n ₁ -1,...5-n ₁ -n. Similarly, the second stage is roofing material 3-n ₂ -
1, 3-n ₂ -2, ... 3-n ₂ -n's lower ends are engaged with the upper ends of the first stage roofing material, and boards 5-n ₂ -1,
5-n ₂ -2, . . . 5-n ₂ -n are sequentially placed, engaged, etc., and fixed via hangers 6 to form the second stage roof. Therefore, the roof is completed by repeating the same operations as described above from the third stage to the nth stage until the so-called heat insulating layer 4 is completely covered.

What has been described above is only one embodiment of the exterior structure according to the present invention, and the insulation layer 4 is formed on the exterior wall in order from the base with the boards 5 and the reinforcing squares 7 interposed, and then the exterior material 3 It is also possible to have an exterior structure with a stepped roof. In addition, as shown in FIG.

It is also possible to create a board 5 that has a good balance between heat insulation and humidity control.

As described above, according to the exterior structure according to the present invention, it is possible to reliably and easily form a heat insulating layer having heat insulating properties, waterproof properties, and humidity control properties on the building frame, so that the building body is protected from dew condensation and the like. Can prevent corrosion of exterior materials. The board functions as a reinforcing material, a step-forming material, and a moisture control material, and can also reduce weight and improve workability. 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. By interposing rod-shaped square members in the triangular space formed between the frame 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. It has the following characteristics.
