Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides waterproof construction by using cross-sectional square cross-section cross-sections and sheathing insulation boards having waterproof, heat-insulating, and moisture-controlling properties between the framework and exterior materials of buildings and structures.
The present invention relates to an exterior structure in which a waterproof and heat-insulating layer having heat-insulating and moisture-controlling properties is formed in a step-like manner to form a stepped roof or a horizontal roof.

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 nail, 3 is an exterior material, 4 is a waterproof insulation layer, and 9 is a Hiroko Mai. To explain further, the exterior material 3 is shown in FIG.
It has the cross-sectional shape shown in ~j and has a stepped roofing structure. The height h is the waterproof insulation layer 4 (hereinafter referred to as
The height H of the sheathing insulation board (hereinafter simply referred to as a board), which is a constituent member of the insulation layer (hereinafter simply referred to as a board), is set to be approximately the same as the height H of a protrusion 5a that also serves as reinforcement and fitting. In addition, among the exterior materials 3, FIGS. 2 a to e and i, j do not require the hanger 6, and f to h are for example 3.
It is fixed via a hanger 6 as shown in Figures a to d. Furthermore, to explain the heat insulating layer 4, the heat insulating layer 4 can be formed from bottom to top using a board 5 and a reinforcing pad 7 as shown in FIGS. 4 and 5 a and b, or as shown in FIGS. As shown in the figure, it is formed from the eaves to the ridge. That is, one of the long side ends of the board 5 is placed on the frame 1, and the short side surfaces are brought into contact with each other and connected horizontally, and the protrusion 5a formed on the long side side end located above the board 5
The long sides of the reinforcing board 7 are brought into contact with the notches 8 provided at the lower corners of the boards, and the short sides thereof are brought into contact with each other. The lower part of the boards is placed and abutted to form a space with a triangular longitudinal cross section between the frame 1 and the board 5, and each is fixed via nails 2, so that the appearance is structured in the form of multiple steps. . To explain in more detail, the first stage 4-n ₁ of the heat insulating layer 4 is constructed by placing one long side end of the board 5 on the wide and small part 9, as shown in FIG.
Place the long side end having a on the frame 1 and abut the short side side of each board 5 to form the board 5-n ₁
-1, 5-n ₁ -2... 5-n ₁ -n are arranged in the order of girder direction, and 7-1-1, 7-1- of the reinforcing floor 7
2...7-1-n, it is interposed in a notch 8 provided at the long side end of the board 5 and fixed with nails 2. In the second stage 4-n ₂ , the long side of the board 5 of the next stage is placed on the half-width surface of the reinforcing base 7,
While placing the other end on the frame 1, the reinforcing pad 7-
2-1, 7-2-2, 7-2-3...7-2-n
Insert it as shown and fix it with nails 3. Therefore, in order to form the heat insulating layer 4, it is sufficient to repeat these steps sequentially from the eave to the ridge. In addition, since the board 5 mainly functions as a waterproofing material, a heat insulating material, a reinforcing material, and a humidity control material, it may be made of wood fiberboard impregnated or coated with asphalt, or made of asphalt powder and refined fibers. It consists of a plate made by heating and pressurizing the mixture. In particular, asphalt impregnation,
Or, the amount of coating should be determined considering waterproofness and humidity control.
10-40% (weight ratio). 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. As shown in Figure 4, its size is L=
200~3636mm, W=150~900mm, T=10~40mm,
H = 3 to 30 mm, Δt = 5 to 15 mm, ΔW ₁ = 5 to 40 mm,
Δd=3 to 20 mm, and ΔW ₂ =5 to 20 mm. The reinforcing bed 7 is made of wood, a hollow pipe, a sheathing insulation board, a synthetic resin reinforcing bar, a member with rubber elasticity, etc., and its length is about 200 to 2000 mm, and the height of the board 5. The cross section is 4 squares, hexagons, 8 squares, deformed ellipses, etc., and is mainly used as a guide when installing reinforcing materials and the board 5, to facilitate the formation of steps, and to reduce the weight of the board 5. It is. Of course, it is insect repellent for breathing and exhausting.
It may also be used as a heat transfer body in solar systems.

Next, a construction example of the above-mentioned exterior structure, such as a roof structure, will be briefly explained. In Figures 1a and b,
First, fix the fascia to one end of the frame, and then fix Hirokomai 9 to the eaves. Next, _{as shown} in FIG _.
-2, 5-n ₁ -3...5-n ₁ -n, reinforcing mats 7-1-1, 7-1-2, 7-1-
3...7-1-n are brought into contact with the notches 8 on the long sides of each board 5 and fixed with nails 2. Next, in order _to construct the second stage of heat insulation layer 4- _{n 2} , as shown in FIG _.
3...Reinforce the long side end as shown in 5-n ₂ -n.
-1-1, 7-1-2... 7-1-n, and the other long side end is placed on the frame 1. Therefore, in order to form the heat insulating layer 4 over the entire frame 1, it is sufficient to sequentially perform the steps described above from the eaves to the ridges. Next, the roofing material, for example _the roofing material _shown in FIG.
Roofing material 3- _{n 1} -1 via a hanger 6 on -n 1 -n,
3-n ₁ -2...Build 3-n ₁ -n. Note that the left end of the roofing material 3-n ₁ -1 is engaged with or placed on the right end edge of the roofing material 3-n ₁ -2 in sequence.
The roof 7-n ₁ of the first stage is roofed by performing this in the girder direction. In addition, the second stage roofing material 3
-n ₂ is the first stage roofing material 3-n ₁ -1,...3-n ₁
-n roofing material 3-n ₂ -1, 3-n ₂ -2, 3
-n ₂ -3...3-n ₂ -n's lower end is engaged, placed on the boards 5-n ₂ -1, 5-n ₂ -2...5-n ₂ -n, and the hanger The roof of the second stage is constructed through the roof 6. Therefore, the roof is completed by repeating the same operations as 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 example of the exterior structure according to the present invention, and boards are formed on the exterior wall in order from the foundation to the eaves, and then exterior materials are applied,
As shown in FIG. 7, a waterproof paper piece 10 for joint covering may be attached to the protrusion 5a of the board 5, and the board may be used as shown by the two-dot chain line during use.

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 base material due to dew condensation, etc. and 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. Because it has moisture control properties, heat insulation properties, and easy distribution, there is no corrosion of exterior materials, rafters, etc., and its lifespan is extended. It has the following characteristics.
