Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a mounting structure for attaching a wall plate forming a wall surface of a building with a good appearance.

[Prior art]

BACKGROUND ART Some buildings have a structure in which a plurality of wall boards with the longitudinal direction oriented horizontally are arranged vertically and fixed to a base material.

When installing wallboards in this manner, if the heads of the fixing nails are exposed on the surface of the wallboards, the appearance of the building will be spoiled and its quality will be degraded. For this reason, in the conventional wall board mounting structure, an overlapping part is formed that is split in half in the thickness direction between the lower and upper edges of the vertically adjacent wall boards, and one overlapping part is placed on the lower edge. It has been proposed that the overlapping part of the other be overlapped with the overlapping part of the overlapping part placed on the upper surface of the overlapping part. With this mounting structure,
The head of the nail that fixed the lower overlapping part is hidden by the upper overlapping part, so that it cannot be seen from the outside.

However, in the above mounting structure, a narrow gap is formed between the overlapping parts of the two panels, so rainwater that has entered the gap from the outside penetrates to the inside surface of the wall board due to capillary action, wetting the inside. I had a problem with it.

In addition, the head of the nail nailed into the lower overlapping part protrudes from the surface in a stepped manner, so when assembling the nail by sliding the tip of the upper overlapping part onto the surface of the lower overlapping part, The tip of the upper overlapping portion may get caught on the head of the nail, impairing the fit of the wallboard. Further, there was a problem in that the leading end of the overlapping portion of the wall plate was damaged due to this catching.

[The problem that the idea aims to solve]

The purpose of the present invention is to provide an overlapping part at the upper and lower edges of the wall panels as described above, and to provide a mounting structure in which the head of the nail is not visible from the outside. Rainwater may enter due to
To provide a wall plate mounting structure that prevents the fitability of the wall plate from deteriorating.

[Means to solve the problem]

The present invention achieves the above object in a wallboard mounting structure in which the overlapping part of the lower edge of the wallboard and the overlapping part of the upper edge of the wallboard overlap as described above. Line grooves 7 and 8 extending in the longitudinal direction of the wall board are provided on the surfaces where the part 5 and the overlapped part 6 on the lower edge side face each other so as to correspond to each other, and the lines of the overlapped part 5 on the upper edge side are provided. Nail 9 in groove 7
This is characterized in that the head is driven into the line groove 7.

As described above, the line grooves provided on the surfaces where the two overlapping parts face each other combine to form a relatively large space. This space enlarges the narrow gap created between the two overlapping parts in the middle, producing a depressurizing effect. Therefore, the rainwater that enters due to capillary action is prevented from further infiltrating to the inner surface of the inner wall board.
In addition, the head of the nail nailed into the lower overlapping part is recessed into the line groove, so when the upper overlapping part is overlapped, the tip will catch on the nail head and the fitting will be difficult. will not worsen.

〔Example〕

The present invention will be explained below with reference to embodiments shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes pillars made of wood or the like that constitute the base material of the building, and a plurality of pillars are erected in rows at appropriate intervals. A vertical rim 3 made of wood or the like is placed on the upper surface of the plurality of pillars 1 through a cushioning material 2 such as asphalt felt, and furthermore, on the upper surface of the vertical rim 3, a longitudinal direction is turned horizontally. A plurality of wall plates 4 are arranged in the vertical direction to form a wall surface.

As shown in FIG. 3, the wall plate 4 forming such a wall surface has overlapping parts 5 and 6 formed in half in the thickness direction at its upper and lower edges. There is. Of these, the overlapping part 5 on the upper edge side has an engaging convex part 5a formed at its tip, and the overlapping part 6 on the lower edge side has an engaging recess 6a formed in its inner corner. ing. Furthermore, line grooves 7 extending in the longitudinal direction (lateral direction) are provided on the surfaces of the respective overlapping parts 5 and 6.
8 is provided.

A plurality of wall boards 4 having the above-mentioned shape are attached to the base material of the building one by one from the bottom, so that the structure shown in FIGS. 1 and 2 is obtained. That is, as shown in FIG. 1, the lower wall board 4 has a nail 9 nailed to the overlapping part 5 on the upper edge side at the line groove 7, and the nail 9 is attached to the vertical rim 3. It is fixed by penetrating it and reaching the pillar 1. The overlapped portion 6 of the lower edge of the upper wall plate 4 is overlapped with the overlapped portion 5 of the lower wall plate 4 fixed in this way, and the overlapped portion 5 of the lower side
The engaging convex portion 5a of the upper overlapping portion 6 and the engaging recess 6 of the upper overlapping portion 6
a and are brought into engagement with each other.

In this way, the overlapping portion 5 of the upper edge of the upper wall plate 4 whose lower edge is assembled to the upper edge of the lower wall plate 4
In the same manner as described above, a nail 9 is driven into the line groove 7 and fixed so that its head is recessed into the line groove 7. By fixing the overlapping portion 5, the upper edge side of the wall plate 4 is fixed, but at the same time, the lower edge side is also fixed so that the engaging recess 6a is fixed to the lower wall plate 4.
It is fixed by engaging with the engaging convex portion 5a, and both the upper and lower edges are securely fixed.
Thereafter, by repeating this process, a plurality of wall plates 4 can be reliably attached one after another.

The fixing nails 9 are preferably stainless steel screw nails, but other common nails or other fixing materials such as screws may be used.

According to the above mounting structure, the top surface of the nail 9 that fixes the overlapping part 5 is covered by the overlapping part 6, so that the head of the nail 9 is not visible from the outside.

Further, when the wall surface 4 is attached as described above, the line grooves 7 and 8 of the overlapping portions 5 and 6 form a gap extending laterally in the overlapping surface of the overlapping portions 5 and 6. The air gap formed by the line grooves 7 and 8 blocks rainwater, etc. that tries to enter the gap between the overlapped parts 5 and 6 by capillary action by a depressurizing effect, and prevents the rainwater from flowing inside. prevent infiltration.

[Effects of the invention] As described above, in the wallboard mounting structure according to the present invention, in the mounting structure in which the overlapping part of the lower edge of the wallboard and the overlapping part of the upper edge of the wallboard overlap, the overlap between the two overlapping parts is Since line grooves are provided on each of the opposing surfaces and these join together to form a relatively large space, the pressure in the narrow gap between the two overlapping parts is prevented from reaching the inner surface from the outer surface of the wall board. During the process, the pressure is reduced, and this reduced pressure effect prevents rainwater that would otherwise enter the inside due to capillary action from further infiltrating into the inner surface of the wall board. In addition, the head of the nail that is driven into the lower overlapping part is recessed into the line groove, so that
When the upper overlapping part is overlapped with the lower overlapping part at the time of installation, the tip thereof will not get caught on the nail head, causing poor fit or damage.
