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 material, and the exterior material is reinforced with the waterproof insulation layer to form a stepped roofing pattern with steps. Regarding exterior construction methods.

In the past, the exterior of a stepped roof structure, for example, the roof, had a structure as shown in FIG.

That is, a roofing board 2 is laid on rafters 1, 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. Further, deformation of the roofing material 6 causes cracks in the coating film and exposes the surface of the roofing material, resulting in a disadvantage that the weather resistance and corrosion resistance of the roofing material are significantly reduced. In other words, the roofing material 6 has a high temperature (
Because they are exposed to harsh temperatures ranging from 60 to 80 degrees Celsius in midsummer to -200 degrees Celsius in the bitter cold, they have 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 these drawbacks, the present invention sequentially constructs soft fiberboard impregnated or coated with asphalt between the exterior material and the base material in a step-like manner, and interposes a caulking material in the overlapping part in a step-like manner. to form a waterproof heat insulating layer, and corrosion of the base and exterior materials is prevented by the waterproof, heat insulating, and humidity control properties of the waterproof heat insulating layer and the triangular void formed between the waterproof heat insulating layer and the base. In addition, we propose an exterior construction method for a horizontally roofed structure with steps in which the exterior material is reinforced with a waterproof and 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. Sunawa (, Figure 3 (a),
(b) is a partially cutaway perspective view and a vertical cross-sectional view showing a roof constructed by the above construction method. Note that parts corresponding to those in FIG. 1 are given the same symbols and numbers. In the diagram, 1 is a rafter, 2
3 is a sheathing board, 3 is a nail, 4 is a roofing (waterproof layer), and 5 is a base, which is either a sheathing board 2 alone or a structure in which a roofing 4 is laid on the shedding board 2. Reference numeral 6 denotes a roofing material which has a cross-sectional shape shown in FIGS. 2(a) to (g) 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. It is something. The waterproof heat insulating layer 7 (hereinafter simply referred to as a heat insulating layer) is composed of soft fiberboard (hereinafter simply referred to as a board) 8 impregnated with or coated with asphalt. Alternatively, the waterproof heat insulating parts are arranged in series through joints 9 formed at slight intervals, and the joints 9 are covered with waterproof adhesive tape IO. , no , , , , 7-Nth stage is a plurality of stages, and their upper and lower ends are overlapped to form a stepped roof. Moreover, each waterproof insulation part 7-no10. .

The vertical positional relationship of the 7-n stage is such that the lower end of the waterproof insulation part of the upper stage overlaps the upper end of the waterproof insulation part of the lower stage (the stage near the girder), and the overlapping part is shown in Fig. 4 (, ). As shown in (b), at least one line of caulking material 11 is planted to strengthen the waterproofness and bonding strength of the overlapping part, and the following empty IIA
.

The humidity control function of the board 8 is always interposed in the circulation of the air without directly circulating the air to the waterproof and heat insulating part. Furthermore, each waterproof and heat insulating part has a triangular vertical section between the base 5 and the back surface 8a of the board 8 which is a component. It is fixed with nails 3 so as to have a ridge to J. Further, the board 8 has a rectangular outer shape as shown in FIG. 5, and its dimensions correspond to, or are longer or shorter than, the roofing material 6.

As a specific example, length L = 200 to 3636 dragons, width W =
The weight is 150 to 600 g, and the thickness t is about 3 to 30 g. In addition, in order for the board 8 to function as a waterproofing material, a heat insulating material, a reinforcing material, and a humidity control material, the board 8 is made by pulping high-quality raw wood, and is further treated with fibrillated and finely-finished materials, water-resistant agents, preservatives, etc. This material is made of insect repellent, asphalt, etc., and is formed into a board. Note that the board 8 is a board whose surface is coated with asphalt, or is impregnated with asphalt before being formed into a board. In particular, the amount of asphalt impregnated is set at 10 to 40% (weight ratio) in consideration of humidity control and waterproofing functions. Moreover, in order to form the heat insulating layer 7, as shown in FIGS. 6(a) to (c), from the first stage waterproof heat insulating part 7-no to the second stage 7-n
Yo, third stage 1619. The roof is constructed by repeating the construction in sequence up to the Ωth stage 7-n.

That is, Figure (a) shows a part of the waterproof insulation part 7-no of the first stage, and one of the boards 8 which is a constituent member is set as 7-no-1 in the eave part and is connected through the nail 3. Fix it. Next 7-n.

=2.7-n-311, near n □ -n, the left and right end surfaces of the boards 8 face each other, and are laid in series on the base 5 through the joints 9, and the lower ends are fixed with nails 3. be. After that, an adhesive tape io is attached to the joint 9 to cover the joint 9. As shown in the next figure
A single row is planted parallel to its upper edge in the so-called eave direction. After that, as shown in Figure (c), the second stage waterproof and heat insulating section 7-01 is constructed. That is, one of the - boards 8 is set as 7-n 7-nl-211660 7-nl-211660 (not shown)
The construction from n to n is carried out in the same manner as the first stage waterproof insulation part 7-no. Therefore, in order to apply the heat insulating layer 7 to the base 5, the above-mentioned process is performed in the third step toward the ridge, and then in the fourth step (not shown) 1011. The waterproof and heat insulating parts may be formed in the order of the n-th stage.

Next, the construction method will be explained. First, Figure 3 (,), (
Assuming that a roof as shown in b) is to be constructed, the heat insulating layer 7 is formed on the base 5 in the order shown in FIGS. 6(a) to 6(C). In this case, the nail 3 may be a screw nail or a general nail, but a zinc needle is preferable. Further, the nails 3 are fixed by either a method of fixing the lower end of the board 8, the so-called overlapping part, or a method of fixing all the upper and lower ends. Next, the roofing material 6 as shown in FIG.

The roof material 6 no 1 is placed on one of the structural members 7-n o 1, and the roofing material 6 no 1 is fixed via the hanger 12 . The right end of the roofing material 6-no-2 is engaged with or placed on the left end of the roofing material 6-no-1, and this is attached to the hanger 1 in the same manner as above.
Fixed via 2. Therefore, the waterproof insulation part 7-0. To install roofing material, follow the above steps in the needle direction.
Roofing materials 6-no-32, , 6no-n may be performed in this order. Moreover, the second stage of roofing material, so-called roofing material 6=n, -1.6 n L 2 , 0. .

The lower end of 6-01-00 (not shown) is used as the first stage roofing material 6

, n, and engages with the upper end portion of the second stage waterproof insulation part 7-
They are sequentially placed on boards 8, which are the constituent members of 01, and fixed via hangers 12 to form the second roof. Therefore, in order to cover the entire roof, it is sufficient to repeat the steps described above from the third stage to the nth stage (not shown) in sequence.

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,
Next, the exterior wall material can also be roofed in a stepped manner. Furthermore, as shown in FIGS. 7(a) and 7(b), a board with moisture-absorbing paper 13 or a waterproof sheet 14 (which has a structure in which numerous holes of micron size are perforated for ventilation) is attached. It can also be used.

Furthermore, a board 8 can also be formed as shown in FIGS. Since it is possible to reliably form a heat insulating layer with moisture control properties, it is possible to prevent corrosion of the base and exterior materials due to condensation, etc. ■ A gap with a triangular vertical cross section is created between the heat insulating layer and the base for each waterproofing layer. Since each heat insulating section is formed independently, the humidity control function of the heat insulating layer can be effectively strengthened.

■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, a three-dimensional exterior can be created with high efficiency and without the need for skill. (2) A caulking material is interposed at the overlapping part, and a waterproof adhesive tape is interposed and coated at the joint between the boards 8, so that a complete waterproof and heat-insulating layer can be formed between the base and the exterior material. It has the following characteristics.
