ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fastened structure wherein flat siding boards such as ceramic siding boards are fastened to the side of a building by making use of a fastening member.
2. Description of the Related Arts
As an exterior finish work of a building, a board siding work for attaching ceramic siding boards (siding boards) to the side of a building is usually performed.
For example, as shown in
FIGS. 11 and 12
, in the case of wood frame construction (two-by-four construction) for example, a framework
1
is assembled at first, and if necessary after an underlayment
2
such as a plywood and a moisture permeable waterproofing sheet is attached to the framework
1
, ceramic siding boards
20
are horizontally fastened via the underlayment
2
to the framework
1
by taking advantage of the studs (vertical frame)
3
of the framework
1
with the longitudinal direction of the siding boards
20
being directed in the lateral direction (horizontal direction).
In this case, a first siding board
20
to be disposed at the lowest portion of the framework
1
is horizontally placed at first to the framework
1
and fastened thereto using screws or nails
4
by taking advantage of upright studs
3
. Then, a second siding board
20
to be fastened over the first siding board
20
is horizontally placed with the lower rabbeted horizontal edge
20
a
of the second siding board being fitted over or engaged with the upper rabbeted horizontal edge
20
b
of the first siding board
20
, and then fastened to the studs
3
in the same manner as illustrated above using screws or nails
4
. Since the head
5
of the nail
4
employed in fastening the siding board
20
is exposed in this case, thus deteriorating the external appearance or design of the finish, a coating coverage is usually subsequently applied to such an exposed head portion of the nails
4
. Further, there is also a possibility that the siding boards
20
may be damaged due to the nailing work.
As an alternative siding work, a method of fastening the siding boards by making use of a fastening member exclusively dedicated for the siding boards has been proposed as taught in Japanese Patent Unexamined Publication H9-203184.
FIG. 13
shows one example of such a metallic fastening member (hereinafter, referred to also as a fastening member)
60
. This metallic fastening member
60
is constructed such that the contacting face portion
61
a
thereof to the underlayment
2
(studs
3
) is disposed parallel with and spaced away by a predetermined distance from the supporting face portion
61
b
thereof for supporting the back surface of a siding board, said predetermined distance being secured by the existence of the connection portion
61
c
and bent portion
61
d
of the metallic fastening member
60
. A mounting portion
62
extending horizontally is projected from the supporting face portion
61
b
, thereby permitting the shiplap portions of a couple of the neighboring upper and lower siding boards
20
A and
20
B to be fitted therein and engaged with each other, the shiplap portions being formed respectively on the horizontal edge portions
20
a
and
20
b
, facing each other, of the neighboring upper and lower siding boards
20
A and
20
B.
The installation of the siding boards
20
can be performed as follows. First of all, as shown in
FIG. 14
, the lowermost siding board
20
B is horizontally positioned by a suitable means. Then, the upper horizontal edge portion
20
a
of the lowermost siding board
20
B is permitted to engage with the underside portion of mounting portion
62
of the fastening member
60
, thereby positioning the fastening member
60
. Then, the fastening member
60
is fixed in place by means of screws or nails
4
. This procedure is repeated to fix a desired number of the fastening members
60
side by side to the studs
3
. Then, the lower horizontal edge portion
20
b
of the next upper siding board
20
A is permitted to engage with the upper side portion of mounting portion
62
of the fastening member
60
that has been fixed in advance, thereby horizontally positioning this upper siding board
20
A. Then, in the same manner as described above, the upper horizontal edge portion
20
a
of this siding board
20
A that has been horizontally positioned is permitted to engage with the underside portion of mounting portion
62
of another fastening member
60
, and then, this fastening member
60
is fixed in place by means of screws or nails
4
. Thereafter, the same procedures as described above are repeated to attach the siding boards
20
horizontally and in multistage to the side of a building, thereby accomplishing a decorative external side.
This fastening method is advantageous in that there is little possibility of damaging the surface of the siding boards, and the existence of the metallic fastening member
60
cannot be externally recognized, thus making it possible to provide a fastened state of siding boards which is very excellent in external appearance. Further, since an air flow space “Sc” can be formed between the siding boards
20
thus fastened and the underlayment
2
in this decorative external side formed in this manner, it is possible to inhibit the generation of dew on the rear side of the siding boards
20
. This fastening method using the aforementioned fastening member
60
is advantageous in that it is applicable not only to a building method using a wood frame but also to a building method using a steel frame.
This fastening method of siding boards using the aforementioned fastening member is very effective in the siding work wherein the fastening of siding boards is executed to the side of a building where studs are regularly arranged at predetermined intervals as in the cases of wood frame construction using a wooden framework, a wooden building according to the traditional Japanese wooden building style, or a steel structure. However, it is difficult to apply this fastening method to an existing mortar-finish or concrete wall where the studs (vertical furring strips) are not exposed from the side of a building. Because, it is difficult to stably attach a large number of fastening members to such a mortar-finish or concrete wall. Therefore, it is not easy to apply this siding work to a so-called reform work where an existing side of a building is covered by a new kind of siding board.
Further, when it is required to exchange some or all of the siding boards with new ones in view of modifying the external design of side of a building or for the purpose of repairing the damage of part of siding boards, the fastening members that have been fixed to the side of a building are required to be dismounted therefrom for the exchange of the siding boards, the fastening members being subsequently reattached to the side of a building by means of nails or screws. Since the insertion of nails or screws into the same locations as the original locations would give rise to the instability of the fastening members newly attached in this fixing work, the locations for attaching the nails or screws are required to be changed to quite new locations, thus making this exchange work troublesome.
Since the fastening member to be employed in the horizontal board siding work is designed to allow the shiplap portion (the underlying tongue portion and the overlying tongue portion) formed on the upper and lower horizontal edge of the siding board to be secured thereto, when a large degree of the surface load is imposed on the front or rear surface of the fastened siding board, the load is mainly borne by the upper and lower fastening members. The siding boards available in the market at present is relatively small in surface area per sheet, so that there is not any particular inconvenience. However, if a fastening method employing the aforementioned conventional fastening member is adopted as it is for fastening a siding board of large surface area which is expected to be placed on the market in future, it would be impossible to secure a suf
