Description

DETAILED DESCRIPTION OF THE INVENTION The present invention prevents corrosion of the foundation and exterior material by forming a waterproof, heat-insulating layer with waterproof, heat-insulating, and moisture-controlling properties in a stepped manner between the foundation and exterior material of a building or structure. The present invention also relates to an exterior construction method in which the exterior material is reinforced with the above-mentioned waterproof and heat insulating layer and roofed horizontally with steps.

The exterior of a conventional stepped roof structure, such as a roof, had a structure as shown in FIG.

That is, a roofing board 2 is laid on the rafters L, this is fixed with nails 3, and roofing 4, such as asphalt felt, is successively laid on top of it to form a base 5. For example, the structure was such that roofing materials 6 as shown in FIGS.

As a result, a wedge-shaped gap A is formed between the roofing 4 and the roofing material 6, and due to the pressure caused by snow accumulation and work on the roof, this gap A may cause the roofing material 6 to deform or the connection part to separate. There were so many things. Moreover, this deformation has the disadvantage of impairing the roof's main function of waterproofing. Furthermore, deformation of the roofing material 6 causes cracks in the coating film and exposes the surface of the roof, which has the disadvantage that the weather resistance and corrosion resistance of the roofing material are significantly reduced. In other words, since the roofing material 6 is exposed to severe temperatures ranging from high temperatures (60 to 80C) to extremely cold temperatures of 20C, it has the disadvantage that even the slightest damage causes rapid deterioration. In addition, the roofing material 6 is in contact with both the inside and outside air on the back and the front surface, respectively, and condensation occurs there, which has the disadvantage of corroding the base.

In order to eliminate such drawbacks, the present invention creates wood fiberboard impregnated with asphalt between the exterior material and the base material in a step-like manner.
In addition, a waterproof and heat-insulating layer is formed by sequentially laying caulking material in the overlapping parts of the mutually interlocking structure, and prevents corrosion of the base and exterior materials by improving the waterproofness, heat-insulating properties, humidity control properties, and This is prevented by the synergistic effect of the triangular void formed between the waterproof insulation layer and the base, and in addition, it greatly improves the work efficiency when polymerizing the fiberboards with each other, and also makes the exterior material waterproof. This paper proposes an exterior construction method for a stepped roof structure with steps reinforced with a heat insulating layer.

An embodiment of the exterior construction method according to the present invention will be described in detail below with reference to the drawings. Parts corresponding to those in Fig. 1 are given the same symbols and numbers. Fig. 3 (al, (b) is a cutaway perspective view and a vertical cross-section showing the case where the construction method according to the present invention is applied to a roof. In the figure, I is a rafter, 2 is a sheathing board, 3 is a nail, 4 is a roofing (waterproof layer), and 5 is a base and a sheathing board 2 alone, or a roofing 4 on the sheathing board 2

Lay the boards from 〇 to the nth stage boards 8-n and -n in series so that the side end surfaces of each board are in contact with each other, and in the direction of the girder so that the long side with the recess 9 at the top end is exposed. Then, in this exposed depression 9, at least one line of caulking material 1o is planted as shown in Figure b), and in this depression 9, a second stage board 8- is planted as shown in Figure B). n-1

(The lower end of 1 is laminated, this overlapping part is fixed through nails 3, and this process is repeated sequentially toward the ridge to create a structure as shown in Figure 6 (81 or (b)). The roof is constructed on the roof.

The board 8 is a rectangular plate with a thickness t of 8 to 30 mm, a depth d of 4 to 20 mm depending on the board thickness, and a width at one edge of the long side. A depression 9 with ΔW of 5 to 2 degrees is provided, and the longitudinal section of the long side end is formed into an L-shape. The recessed portion 9 is effective as a guide during construction and to prevent the air inside the gap from circulating with the gaps in other stages. Furthermore, the width W of the board 8 is 150 to 60
oIm, the length L is about 200 to 3636111, and in order to make the board itself function as a waterproofing material, a heat insulating material, and a humidity control material, about 1.
It is impregnated with 0 to 40% (weight ratio) or coated on the surface. Also.

The raw materials for board 8 are high-quality wood logs made into valves, which are then defibrated and refined, as well as water-resistant agents, preservatives, insect repellents, and asphalt.

Next, the construction method for the above roof will be explained.

In FIG. 3(a), first, as shown in FIG. 6(a), the entire surface of the base 5 is coated.
) is formed from the eaves to the ridge. In this case, the nail 3 may be a screw nail or a general nail, but a zinc nail is preferable. Further, the nails 3 are fixed either at the lower end of the board 8, the so-called overlapping part, or at all the upper and lower ends. Thereafter, the roofing material shown in FIG. 2(e) is attached to the first board 8-n.

It is fixed via hangers 11 and the second stage roof is covered.

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 7 is completely covered.

This is just one embodiment, and it is also possible to form the heat insulating layer 7 on the outer wall in order from the L base, and then layer the outer wall material in a stepped manner. Furthermore, as shown in FIG. 7 (al to (C)), a moisture-absorbing paper 12 or a waterproof sheet 13 (which has a structure with numerous micron-sized holes for ventilation) is pasted on one side of the board 8. By planting the board and the caulking material 10 at the corner of the depression 9, the caulking material and the depression can be effectively used to create a heat insulating layer between the base and the exterior material that has heat insulation, waterproofness, and moisture control properties. Since the coating can be easily and reliably formed, corrosion of the base material and exterior material due to dew condensation etc. can be prevented.

■By forming a void with a triangular longitudinal cross section between the heat insulating layer and the base, the humidity control function of the heat insulating layer can be promoted. ■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 withstand external forces sufficiently.

■Since the exterior material is constructed in a stepped manner, it is possible to create a three-dimensional exterior with high efficiency and without the need for skill. It has the following characteristics.
