Description

[Detailed explanation of the invention] (Industrial application field) This invention is a method for installing clapboards (horizontal paneling of walls) in corner corners (inner corners created when two walls of a building meet at an angle). This relates to a back-up material used for the butting part of the end of horizontal plates (horizontal plates attached so that they overlap each other little by little).

(Prior Art) Conventionally, as shown in FIG. 4, a metal joiner 13 bent in an L-shape is attached to the outer surface of the clapboard with a sealant 14 interposed in the corner projection formed by the clapboard. I touched it and it was nailed down.

(Problem to be solved by the invention) If the clapboard installed on the wall has a concave and convex pattern that continues in the longitudinal direction, the end of the clapboard on one wall at the inside corner is Since it contacts the vertical surface of the wall, positioning of the end surface is easy. However, since the end surface of the clapboard on the other wall faces the uneven sloped surface of the outer surface of the one clapboard,
Its positioning is not easy.

It is difficult to form a metal joiner that fits into such a corner, and what is more, a sawtooth-like gap is created at the end of the clapboard in the corner. When sealing the gap with a sealant, the gap is large and a large amount of sealant is required.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a back-up material that can be easily applied to the corner projecting portion of a clapboard that has a concave-convex pattern continuous in the longitudinal direction and requires a small amount of sealant.

(Means for Solving the Problems) A feature of the present invention for achieving the above-mentioned object is a back-up material provided at the corner protrusion formed by mutually orthogonal clapboards. One side of the back-up material is formed into an uneven surface that follows the uneven shape of the outer surface along the longitudinal direction of one of the clapboards, and is attached in the vertical direction to the outer surface of the end of the clapboard. The other side opposite to is formed in a vertical plane and is in contact with the end surface of the other siding board.

(Function) According to the present invention, when the back-up material is attached with the uneven surface of the back-up material attached to the outer surface of the end of one of the clapboards at the corner projecting portion, the back surface of the back-up material becomes a vertical surface. By bringing the end surface of the other siding board into contact with this vertical surface, the end surface of the siding board can be reliably and easily positioned.

Moreover, since the space between the corner protrusions formed by both clapboard ends is reduced by the back-up material, the amount of sealant filled in the space is smaller than in the conventional case. .

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

What is shown in FIG. 1 is a backup material 1 of the present invention. This backup material 1 is molded from an organic foamed resin (for example, foamed polyethylene).

One side of the backup material 1 is formed into a sawtooth-like uneven inclined surface 2. The other side facing the inclined surface 2 is formed into a flat surface 3. The other side surfaces perpendicular to this flat surface 3 are also formed into flat surfaces. An adhesive and release paper are attached to the inclined surface 2.

The backup material 1 is used as shown in FIG. That is, in Fig. 2, 4 is a pillar;
Reference numerals 5 and 6 designate furring edges that are perpendicular to each other, and 7 and 8 designate clapboards, which have continuous serrated irregularities in the longitudinal direction. The ends of the clapboards 7 and 8 attached to the mutually perpendicular edges 5 and 6 are butted against each other to form a corner protrusion 9.
is formed.

The end face of one of the clapboards 7 of the inside corner projecting portion 9 is positioned in contact with the wall surface 6, and the inclined surface 2 of the backup material 1 is in contact with the outer surface of this clapboard 7. The back-up material 1 is attached by peeling off the release paper stuck to the inclined surface 2, and the back-up material 1 is adhered to the inclined surface 2 via an adhesive.

The serrated uneven inclined surface 2 of the back-up material 1 is shaped to fit into the saw-toothed uneven inclined surface of the outer surface of the Nanjing siding 7 along the longitudinal direction, so the back-up material 1 is formed on the outer surface of the Nanjing siding 7. A tight fit. In this attached state, the backup material 1
The flat surface 3 facing the inclined surface becomes a vertical surface. The end surface of the other siding board 8 comes into contact with this vertical surface 3.

The inside corner protruding portion 9 formed as described above has a space between
Since this occurs, a sealing material 10 is filled in the gap, and the gap is sealed. This sealing material 10 is made of oil-based caulking, elastic sealing material, or the like.

Since the back-up material 1 is made of foamed resin, this sealing material 10 does not adhere to the back-up material 1 when cured, but only to both siding boards 7 and 8, so there is no three-sided adhesion, and there is a difference in thermal expansion. No internal stress distortion occurs. Furthermore, the amount of sealing material 10 used can be reduced by using backup material 1. 11 is asphalt felt.

In addition, what is shown in FIG.
The side that comes into contact with the outer surface is formed into a serrated uneven inclined surface 2, and the side that is filled with the sealant 10 is also formed into a serrated uneven inclined surface 12.

In this way, the side where the sealant is filled also has an inclined surface 12.
By forming the sealing material 10 into a uniform shape, the thickness of the sealing material 10 becomes uniform, and the internal stress after the sealing material hardens becomes uniform, thereby improving durability. Furthermore, the amount of sealant 10 used is further reduced.

Note that the adhesive may be applied to the side surface on the wall surface side.

In addition, the uneven sloped surface 2 of the backup material 1 and the serrated unevenness of the clapboards 7 and 8 shown in FIGS. 1 and 2 are exaggerated and drawn in a large scale to make it easier to understand the features of the present invention. be.

In addition, in the case shown in FIGS. 5 to 10, a back-up material 50 having the same shape as above is attached to a window frame 51.
It was used for the vertical joints 52 of .

That is, a Nanjing clapboard-shaped clapboard 53 and a window frame 51
A back-up material 50 shown in FIG. 10 is attached to a vertical joint 52 formed at the joint with the back-up material 50 shown in FIG.
The flat surface of the backup material 50 shown in FIG. 10 is coated with an adhesive to which a release paper is attached.
By peeling off the release paper, the flat surface of the back-up material 50 is adhesively fixed to the window frame 51, and the serrated uneven slope surface 54 is aligned with the slope surface of the clapboard 53, thereby increasing the height of the opening of the vertical joint 52. The thickness in the width direction becomes uniform, and the thickness of the sealing material 55 filled in the joint 52 becomes uniform. Since this back-up material 50 is molded from an organic foamed resin, the sealing material 55 does not adhere, thereby preventing three-sided adhesion.

Incidentally, what is shown in FIG. 11 is a backup 56 that is n times the one shown in FIG. 10. Also the first
What is shown in Figure 2 is a backup material 57 used for horizontal joints.

What is shown in FIGS. 13 to 18 relates to a parting edge joiner 60.

In the case of Nanjing siding and armor 61, the thickness at the parting part 62 varies depending on the location of the building, as shown in Figures 13 to 18. Therefore, it is necessary to use a parting edge joiner 60 with a different dimension a.

The parting edge joiner 60 shown in the figure is a single piece that can freely change the dimension a.

That is, as shown in FIG. 14, the parting edge joiner 60 is made of a metal thin plate, and a slit 63 of a certain length is inserted in the bent edge to facilitate bending.
The dimension a shown in FIG. 15 can be freely obtained.

(Effects of the invention) According to the invention, construction of the corner protrusion becomes easy and the appearance becomes beautiful. Moreover, the amount of sealant used can be reduced.
