DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a construction method useful for constructing a stepped exterior covering on the base of buildings and structures.

[Structure of the invention]

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. 1 shows an example of a roof constructed by the above construction method. In the figure, 1 is a rafter, and 2 is a base (sheath board in the figure), which is laid on top of the rafter 1 from the eaves to the ridge. Reference numeral 1 denotes a heat insulating layer, which is formed by laying a plurality of heat insulating materials 4 as shown in FIG. 2 in the direction of the eaves (horizontal direction) with their respective side surfaces 4a in contact with each other. It functions as a heat insulating material, a back-up material, a sound insulating material, a step forming material, and a spacer between the base 2 and the exterior to be described later. To explain in more detail, the heat insulating layer has a core material 5 whose outer shape is rectangular and whose longitudinal section is curved.
Then, a waterproof sheet 6 formed in a size that protrudes from two adjacent sides of the core material 5 is attached to the back surface of the core material 5, and 1.
, a plurality of heat insulating materials 4 each having overlapping tongues 6a and 6b protruding by J2 are laid in series in the direction of the eaves (horizontal direction) on the base 2 with the side surfaces 4a formed on their short sides touching each other. This is what I did. In particular, the insulation material 4 has one of its long sides as a thin section,
The other long side is the thick part, and the thin part end face 4b and the thick part end face 4c are formed in a cross section connected in series, and the thin part end face 4b

The core material 5 may be made of polyurethane foam, polyisocyanurate foam, phenol foam, rock wool, sheathing board, polystyrene foam, polyethylene foam, modified foam thereof, or pearlite grains, vermiculite, etc. in the structure of these foams. It is formed from a foam mixed with one or more types of whitebait balloons and mineral fibers. Furthermore, the waterproof sheet 6 may include aluminum foil, water-repellent kraft paper, asbestos paper or non-woven fabric, asphalt felt, Teflon sheet, etc.
It is a laminate of one or more of PVC sheets, polyethylene sheets, and lead foil. Yu is the third on the exterior.
The exterior material 8 as shown in the figure is placed on the heat insulating layer 1, and the left and right ends are overlapped with each other, and is mainly used as an exterior wall material and roof material. To be more specific,
The exterior material 8 is mainly made of a surface-treated steel plate, stainless steel plate, copper plate, aluminum plate, etc. formed into a desired shape. An example of a specific exterior material will be explained using Fig. 3.

This is what I did. That is, the overlapping uneven portion 10 has two or more uneven stripes 10a formed on the left and right ends of the main body 11 and the locking portion 13 to strengthen the waterproofness of the overlapping portion of the exterior material 8. Further, the rising portion 12 serves as a guide for the heat insulating material 4 and as a step forming member. Further, the stepped portion 14 engages a locking portion 13 that is engaged with a locking portion of a fixture to be described later.

[Construction example]

Next, a construction example will be explained.

Now, as shown in Fig. 5(a), the base 2 is laid on the rafters 1, and the base is formed using a nose cover 16, a wide width 17, a Karakura 18, and a heat insulating material for adjusting the rod. It is assumed that the insulation layer weight -n0 is the same as the one above, and that the exterior knee no. of the stem part has already been roofed. Therefore, a first stage heat insulating layer 3 nI is formed at the next stage of the exterior knee n0. That is, a plurality of heat insulating materials 4 as shown in FIG. 2 are placed in contact with each other with their side surfaces 4a, and the heat insulating materials 4 (3-n, -1, not shown) are placed in the direction of the eaves as shown in FIG. 5(a). The first stage of insulation N3n is laid in order in the direction of the eaves, and the side surface of the insulation material 4 to be laid next without the polymer tongue piece 6b is placed on the polymer tongue piece 6b.
Form +. At this time, the thin-walled portion end surface 4b is laid in the ridge direction, and the thick-walled portion end surface 4c is laid in contact with the exterior work-n0 and the rising portion 15a of the fixture 15. Next is the heat insulation layer 3-n.

The exterior work-n1 of the first step entrance is roofed on top as shown in FIG. 5(b). That is, a plurality of exterior materials 8 as shown in FIG. 3 are arranged in series in the direction of the eaves with their overlapping uneven portions 1o superimposed on each other, and the retaining portion 14 is a mounting tool for exterior exterior 7-no of the rod portion. 15, the rising portion 12 is flush with the end surface 4b of the thin wall portion, and the locking portion 13 is engaged with the locking portion 15b of the fixture 15, The fixing portion 15c is fixed to the base 2 via nails 19. Next, the second stage heat insulating layer knee nz is laid as shown in Fig. 5 (Fig. 5). That is, 3 nz consisting of insulation material 4

In order to roof the second stage, the exterior material 8 is placed on the second stage heat insulating layer 3-n in the same way as the first stage exterior to form a common roof. Therefore, in order to cover the entire roof, it is sufficient to repeat the steps described above in sequence from the eaves to the ridge. The cross section of the overlapping part (X-X line) of the roof constructed in this way is as shown in FIG. 6 [Other Examples] The above explanation is based on the exterior construction method according to the present invention. This is just one example, and it is also possible to construct the outer wall rim and studs in order from the foundation to the girder. In addition, the exterior material 8 is shown in FIG.

It is also possible to form the sheath using a separate seam material for this connection. Furthermore, as shown by the two-dot chain line in FIG. 2, the heat insulating material 4 can also be formed by integrally adhering the waterproof sheet 6 to the surface side of the core material 5.

〔Effect of the invention〕

As described above, according to the exterior construction method of the present invention, a waterproof layer and a heat insulation layer can be formed by simply laying the insulation material in series horizontally on the base, and the exterior construction can be performed using this insulation layer as a guide. Then, the second layer of heat insulation is formed using this exterior as a guide, so it does not require any skill to install and can be easily installed even by amateurs. Additionally, since a heat insulating layer is reliably formed between the exterior and the base, the exterior has excellent heat insulation properties. Furthermore, the insulation layer functions as a back-up material, waterproofing material, vibration-proofing material, cushioning material, and sound-absorbing material, so it protects the foundation and rafters from corrosion.
It has the feature of preventing deformation of the exterior material due to external pressure (snow), etc. Furthermore, the exterior material has a simple shape and the mounting tool has a simple structure, so it has the advantage that it can be produced at low cost. Furthermore, the exterior is terraced, giving it an excellent three-dimensional feel.
