Description

DETAILED DESCRIPTION OF THE INVENTION The present invention does not require the formation of a flat base for the rafters and trunk edges of buildings and structures, but instead combines the base, reinforcing material, and step in one member to create a stepped structure. Concerning a construction method that can roof the exterior with high efficiency.

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 roofing material 6 having a step height h as shown in FIG. A wedge-shaped gap A is formed in between, and this gap A is affected by snow accumulation and pressure from work on the roof, which often causes the roofing material 6 to deform or the connection to separate. Deformation has the disadvantage of impairing waterproofness, which is the main function of the roof.Furthermore, deformation of the roofing material 6 can cause cracks in the paint film and expose the skin, which can impair the weather resistance and corrosion resistance of the roofing material. In other words, the roofing material 6 has the disadvantage of significantly reducing the
Since it is exposed to severe temperatures of up to 200 degrees Celsius, 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 does not use a base as in the past on the rafters and girders, but instead serves as a base, a step forming member, and a backing material for the exterior material, and at the time of construction. This paper proposes an exterior construction method that uses boards that also have a guiding function.

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),
(bl shows the case where the above construction method is applied to the roof, +81 figure is a partially cutaway perspective view, (k)) Figure 1
a) It is a sectional view taken along the line 1-1 in the figure. In the figure,
10 is a rafter, the opening is a base, and the base part I2 is the first stage l2-n
A recess 14 is provided in at least one line part of the upper and lower ends of a rectangular board 13 (hereinafter simply referred to as a board) that is a constituent member of a plurality of stages from o to n-th stage 12-0, and a recess 14 is provided in the recess I4. A caulking material 15 is planted and polymerized through the depressions 14 to form a stepped roof from the eaves to the ridge. [Caulking material] 5 is planted in the recess I4 in one or two strips with a semicircular, trapezoidal, or sheet-like longitudinal cross section to strengthen the bond between the boards 13, provide waterproofness and heat insulation, It also functions as an absorber for dimensional errors in the joints between boards and as a buffer against impact vibrations. 16 is a step on the base roof with a waterproof sheet.

The joints between the boards 13 prevent water from leaking from the joints 8 and also prevent direct contact between the base and the roofing material 17. The shape of the roofing material 17 is shown in FIG. 2(a) above.
Since it is the same as ~(g), both the explanation and illustration will be omitted. Here, to further explain the base layer LL, the structure is such that the board 13 as shown in FIGS. 4(d) and (I)) is constructed as shown in FIGS. 5(al to (C7)). In other words, the figure (,) shows a recess 14 at the upper end of the base portion 12.
Boards 13 having the following properties are laid in series in the direction of the girder to form the first stage base part 12 no. Next, one strip of caulking material 15 is planted in the recessed part 14 in the direction of the girder. The lower end of the □ portion l2-n1 of the base of the second stage is laminated and superposed on the hollow part 14, and then 110. This is the base U formed by repeating the steps up to the ridge.

In addition, in the fb) figure, there is no recess 14 at the upper end of the second stage base part 12n1, there is a recess 14 at the lower end, and the recess 14 is at the upper end of the first stage base part +2 no. The base opening is formed by repeating the polymerization structure up to the 116th ridge. Furthermore, (in Figure C1, recesses 14 are formed at the upper and lower ends of the board 13, and the first stage base part 12 no.
The upper end and the lower end of the second-stage base section 12-n overlap in a mutually interlocking structure, and the caulking material 15 is interposed in the overlapped part, and this structure is repeated until the ridge is formed. Note that the base portion 12 is a board 13, with its left and right end surfaces in contact with each other in the girder direction via joint portions 18, as shown by the numbers attached for so-called identification, or laid in series with a slight interval, The one-line part is fixed with nails 19, and attached to the rafters 10 so as to form a gap 20 having a triangular longitudinal section. is 12-no-], 12-no-2, 12

Further, the relationship between the upper and lower levels of the base part 12 is such that there is a step difference h, and the upper and lower ends of the base part 12 overlap via the so-called recessed part 14 of the board 13. Note that the longitudinal section of the end portion where the recessed portion 14 is formed is L-shaped. Further, the board 13 is made of a hard board such as plywood, and its size is width W=1.
50 to 900 wTn, length L = 200 to 3636 mm, thickness t-10 to 30 mm, and recessed portion 14 is △W = 5 to 40 mm. ．． ,

It is preferable that it is between 5 and 5. In addition, the difference in level is roof material 17
is the same as the height h.

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

Now, the roof as shown in Figure 3 fa) and (b) is
Assume that construction is performed using board I3 shown in Figure (a). Therefore, the base 12 as shown in FIG. 5 (al) is formed on the rafter 10 using the board shown in FIG.
A caulking material 15 is interposed in the depression 14 to form a step-like structure. Next, attach the waterproof sheet 16 to the staples 21.
It is laid sequentially from the base part l2-no to l2-no through the base part l2-no. In addition, when installing on a step, the L-shaped cross section is installed so as to cover the step and also cover the upper end of the step that is close to the eaves by a width of Δl.

Next, the mechanism 22 is fixed to the eaves with nails, and the roofing material 17 (the so-called first-stage roof part l7-no) is attached to the first-stage base part 12n from above.

What has been described above is only one embodiment of the exterior construction method according to the present invention, and the construction can also be carried out sequentially from the foundation to the girders on the rim and studs of the exterior wall.

As mentioned above, according to the exterior construction method of the present invention, ■ the use of a single sheathing board on the exterior material and the rim or on the rafters is eliminated, and the base material, reinforcing material, and step member are combined into one member; It is a combination of both.

■Since a recess is formed at the end of the board, it serves as a guide during base construction and promotes a mutually integrated structure at the overlapping part, allowing for higher efficiency and easier construction. ■Because a special base and waterproof sheet were interposed between the exterior material, rafters, and rim,
It can prevent corrosion of exterior materials, rafters, etc. ■There is no deformation of the exterior material because there is a hard board behind the exterior material with a waterproof sheet in between. ■The exterior is constructed in a tiered manner, giving it a three-dimensional appearance. ■Because the caulking material is interposed in the area where the base and base parts overlap, the bonding force between the boards is strengthened, and it also provides waterproof and heat insulation properties, as well as vibration-proofing, cushioning, and dimensional error absorption properties. Equipped with. It has the following characteristics.
