Description

[Detailed Description of the Invention] The present invention provides waterproofing between the exterior base and exterior material of buildings and structures.
A waterproof insulation layer with heat insulation and moisture control properties is formed in a stepped roofing pattern to prevent corrosion of the base and exterior materials, and the exterior material is reinforced with the above-mentioned waterproof insulation layer to create a stepped roofing pattern. Concerning exterior construction methods for roofing.

The exterior of a conventional stepped roof structure, for example #f roof, is
As shown in the figure, it has a structure like this.

That is, a roofing board 2 is laid on rafters 1, fixed with nails 3, and a roofing board 4 and asphalt felt are successively laid on top of it to form a base 5. It had a structure in which, for example, roofing materials 6 as shown in FIGS. 2(a) to ('#) were sequentially fixed via hangers 10 thereon.

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 roofing material, which has the disadvantage that the weather resistance and corrosion resistance of the roofing material are significantly reduced. In other words, the roofing material 6 is exposed to severe temperatures ranging from high temperatures (60 to 80C in mid-summer) to 120 liters in severe cold, so 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 has been developed by using soft fiberboard impregnated or coated with asphalt between the exterior material and the base material in a step-like manner, and by interposing a caulking material in the double-layered part to form a horizontal roofing pattern. Forms a waterproof insulation layer by laying
The waterproofness of the above waterproof insulation layer prevents corrosion of the base and exterior materials.
We propose an exterior construction method for a horizontal roofing structure that has insulation properties, moisture control properties, and a triangular gap formed between a waterproof insulation layer and the base, and that has steps where the exterior material is reinforced with a waterproof insulation layer. It is something.

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),

2 is the roof board, 3 is the nail, 4 is the roofing (waterproof layer), 5
This structure consists of either a sheathing board 2 alone as a base, or a structure in which a roofing 4 is laid on the shedding board 2.

Reference numeral 6 denotes a roofing material, which has the cross-sectional shape shown in Fig. 2(a) to (2) and has a stepped roofing structure, and its height h corresponds to the thickness of the constituent members of the waterproof and heat-insulating layer 7. The waterproof heat insulating layer 7 (hereinafter simply referred to as a heat insulating layer) is made of a plurality of soft fiberboards (hereinafter simply referred to as boards) 8 impregnated with or coated with asphalt (hereinafter simply referred to as boards) arranged in series with their side edges touching. The first stage 7-n
The roof is made up of multiple steps from o to 7-nn, with their upper and lower ends overlapped to form a step-like roof. Moreover, the upper end of the board 8 is in contact with the base 5, and the lower end is overlapped with the upper end of the latter stage,
In addition, at least one line of caulking material 9 is planted in the overlapping part as shown in FIGS. 4(a) and 4(b) to improve the waterproofness of the overlapping part.
In addition to strengthening the bonding force, the humidity control function of the board 8 is always used to circulate the air without directly circulating the air in the gap A described below to the waterproof insulation part. Furthermore, the board 8 is fixed via nails 3 between the back surface 8a of the board 8 and the base 5 so as to form an air N A' having a triangular longitudinal section. The board 8 has a rectangular outer shape as shown in FIG. 5, and may be formed to correspond to the roofing material 6, or to be longer or shorter as necessary. be.

As a specific example, length L=200-3636slIm,
Width W=150-60.0. ,,thickness t is 3-73011
．． It is number 1. Moreover, in order to function as a waterproofing material, insulation material, reinforcing material, and humidity control material, the board 8 is made of high-quality wood raw wood that is pulped, then fibrillated and refined, and contains water-resistant agents, preservatives, and insect repellents. , asphalt, etc. are used as raw materials. Moreover, the board 8 is intended to be formed into a board from this raw material, and its surface is coated with asphalt, or it is impregnated with asphalt before being formed into a board. In particular, the amount of asphalt impregnation is controlled by humidity control.
The content is set at 10 to 40% (weight ratio) in consideration of the performance of the waterproof function. In addition, the heat insulating layer 7 is shown in Figures 6) to (c).
As shown in K, the roof can be constructed by repeatedly constructing a plurality of waterproof and heat insulating sections in sequence.

That is, (as shown in Figure 81, the first stage waterproof insulation part 7-no is board 8-no-1, 8-n-21,
, 8n o - n are laid horizontally and in series, and the lower ends are fixed with nails 3. Next, as shown in figure (b), apply caulking material 9 to the upper end of the waterproof insulation part 7-.

The caulking material 9 is laminated at the upper end of the caulking material 9 in the area where the caulking material 9 is present, and this overlapping portion is fixed with nails 3. Therefore, the heat insulating layer 7 is a waterproof heat insulating section in multiple stages from the eaves to the ridge. -n It is constructed by forming n.

Next, the construction method will be explained. First, Figure 3(a), (
Assuming that a roof as shown in b) is to be constructed, a heat insulating layer 7 is formed on the base 5 in the order shown in FIG. Although any type of nail may be used, zinc nails are preferred.Furthermore, the nails 3 are fixed by either fixing the lower end of the board 8, the so-called overlapping part, or by fixing all the upper and lower ends.

Thereafter, the roofing material shown in FIG. 2(e) is placed on the first board 8 no 1, and the roofing material 6-no-1 is fixed via the hangers 10. By sequentially engaging or placing the left end of the roofing material 6-no-1 on the right edge of the roofing material 6-no-2 in the girder direction, the first stage board 8-no-1t- 8-n On top of the first stage roof. In addition, the second stage is roofing material 6-n-1,

, , 8-n is placed and engaged in order on knee n, and is fixed via hangers 10 to form the second roof. From the stage to the nth stage 1. This process is completed by repeating the process until the so-called heat insulating layer 7 is completely covered.

What has been described above is only one embodiment of the exterior construction method according to the present invention, and the insulation layer 7 is formed on the exterior wall in order from the foundation,
It is also possible to construct the exterior wall material in a stepped manner. Furthermore, as shown in FIGS. 7(a) and 7(b), a board with moisture-absorbing paper 11 or a waterproof sheet 12 (which has a structure in which numerous holes of micron size are perforated for ventilation) is attached. It can also be used.

Furthermore, the board 8 can also be formed as shown in Figures 8) to (C).
