Description

[Detailed Description of the Invention] The present invention provides waterproofing between the exterior base and exterior material of buildings and structures.
An exterior structure in which a waterproof and heat-insulating layer with heat-insulating and moisture-controlling properties is formed in a stepped manner to prevent corrosion of the base and exterior materials, and the exterior material is roofed on top of the waterproof and heat-insulating layer in a stepped manner according to the level difference. Regarding construction methods.

The exterior of a conventional terraced roof structure, for example, the roof, had a structure as shown in Figure 1. In other words, the roofing board 2 was laid on the rafters L, and this was fixed with nails 3. Roofing 4, for example, asphalt felt is layered one after another to form a base 5, and on top of that, roofing material (2) as shown in Fig. 2, 18) to (g), is applied via hangers (2). It was a structure that was fixed in stages.

As a result, a wedge-shaped space 1 is formed between the roofing 4 and the roofing material 6.
A gap A was formed, and the roofing material ■ was often deformed or the joints separated due to snow accumulation and pressure from work on the roof. Moreover, this deformation has the disadvantage of impairing the roof's main function of waterproofing. Furthermore, deformation of the roofing material O causes cracks in the coating film and exposes the surface of the roofing material, 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 (2) is exposed to severe temperatures ranging from high temperatures (60 to 80C in midsummer) to 20C in the bitter cold, it has the disadvantage that even the slightest damage causes rapid deterioration. In addition, the roofing material (2) has the disadvantage that both the inside and outside air come into contact with each other on the back surface, which causes dew condensation, which corrodes the base.

In addition, the waterproof roofing had to be laid on the roofing board 2. In order to eliminate this drawback, the present invention has installed asphalt-impregnated or coated boards between the exterior material and the base, at the top, bottom, left and right ends. By forming a concave structure in the area and laying it in a step-like manner through this concave structure, a reliable waterproof and heat-insulating layer can be easily constructed, eliminating asphalt roofing and preventing corrosion of the base and exterior materials. A stepped roofing structure with steps that is prevented by the waterproof, heat insulating, and humidity control properties of the waterproof heat insulating layer and the triangular gap formed between the waterproof heat insulating layer and the base, and the exterior material is reinforced with the waterproof heat insulating layer. This project proposes an exterior construction method.

An embodiment of the exterior construction method according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 3(a),

In addition, in the figure, A is a gap and B is a hanger.

To explain further, the waterproof heat insulating layer 4 (hereinafter simply referred to as the heat insulating layer) is made by stacking the ports 5 as shown in FIG. When fitted, the first stage waterproof and heat insulating part 4 is connected to the component 4 consisting of the board 5.
11, 2 (not shown) are constructed and formed in the order of 4 no n, and then the second stage waterproof insulation part 4-row is formed by attaching the component 4-n to the upper end of the first stage waterproof insulation part 4-n. −

This process is then repeated in the third stage and fourth stage 094. The roofing was repeated until the waterproof and insulating part of the nth stage was constructed, resulting in a stepped roof.

Moreover, a vertical section is formed between the rear surface 5a of the so-called board 5 and the sheathing board 2 with a triangular vertical cross section. It should be noted that the gap A' acts as an adjustment section to promote the humidity control function of the board 5. Also, board 5
is formed into a rectangular shape as shown in FIG.
6.7.7 was formed. Moreover, the thickness t of the board 5 is 8 to 30 m1, and the depth △d of the depressions 6 to 7 is 4 to 30 m1.
20 mm, and the width ΔW is 5 to 20 mm. Furthermore, the size of the board 5 is L=200~3636, W=
100 to 900@@, and this board 5
In order to make the board 5 waterproof and moisture-controlling as well as function as a reinforcing material, for example, raw wood of high quality wood is pulped and further fibrillated and refined, waterproofing agents, preservatives, insect repellents, and asphalt are used. etc., which is formed into a plate of a predetermined shape and thickness, and the surface of which is coated with asphalt, or which is impregnated with asphalt before being formed into a plate. In particular, impregnation of asphalt,

~40% (weight ratio). This is because if the amount of asphalt impregnated is less than 10%, it will lack waterproofness, and if it is more than 40%, it will not be able to expect much moisture control, or so-called breathability, and there is a risk of a decrease in insulation properties. We will explain the case where it is applied. Assume that a roof as shown in FIGS. o 1 is the component 4-n of the first stage waterproof insulation section 4-no.

Also, roof material g no. 2 is component 47 n.

-2, the right end is engaged with or placed on the left end of the roofing material 8-no-1, and the upper end thereof is fixedly wrapped around the roof material 8-no-1 via the hanger B. These steps are performed sequentially on the waterproof heat insulating part 4-no of the first stage in the girder direction to complete the construction of the roofing material 8 on the waterproof heat insulating part 4-no. In addition, the second stage roof 8-n is a roofing material 8-n 21 which is a constituent member thereof.

The construction can be repeated in the same manner as above until n.

What has been described above is only one embodiment of the exterior construction method according to the present invention, and the insulation layer 4 is formed on the exterior wall from one unit to 11111n, and then the exterior wall material is roofed in a stepped manner. It is also possible. The heat insulating layer 4 is made by attaching a waterproof adhesive tape 9 to the board 5 as shown by the dashed line in FIG.
It can also be pasted so as to cover only the joints in between.

Furthermore, as shown in FIG.
It is also possible to use a board 5 on which moisture-absorbing paper or a waterproof sheet (provided that a number of micron-sized holes for ventilation are perforated) 10 are adhered to one flat surface. Although not shown, if caulking is used in the recesses, it is possible to reliably form a heat insulating layer between the base and the exterior material that has heat insulation, waterproofness, and humidity control properties, thereby preventing condensation.
Can prevent corrosion of base and exterior materials. ■By forming a void with a triangular vertical cross section between the heat insulating layer and the base, the humidity control function of the heat insulating layer can be promoted.

■Since the insulation layer has recesses with a matching structure at the four ends of the board, which is a component, it functions as a ruler when installing the exterior material, making it easier to install the exterior material.0 ■The exterior material is placed on the insulation layer. Because it is placed and fixed on the surface, it can withstand external forces sufficiently. ■Since the exterior material is constructed in a stepped manner, a three-dimensional exterior can be created with high efficiency and without the need for skill. It has the following characteristics.
