CROSS-REFERENCES TO RELATED APPLICATIONS
The present application claims priority under 35 U.S.C. § 119 to Japanese Patent Application No.2000-319735, filed Oct. 19, 2000, entitled “FASTENING MEMBER AND SIDING BOARDS ATTACHMENT STRUCTURE”. The contents of this application are incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fastening member for fixing a siding board to a framework of a building, and further relates to a siding boards attachment structure using the fastening member.
2. Discussion of the Background
Conventionally, there are used siding boards attachment structures of a type as shown in
FIG. 14
by way of example. The figure shows a siding boards attachment structure
8
formed such that a fastening member
9
is disposed to engage an upper horizontal edge
21
of a lower siding board
2
and a lower horizontal edge
22
of an upper siding board
2
, and the siding boards
2
and
2
are fixed to a framework
3
of a building via a furring strip
89
or the like.
As shown in
FIGS. 14 and 15
, the fastening member
9
has a base plate portion
91
, a support portion
92
, an upper-board engagement portion
93
, and a lower-board engagement portion
94
. The base plate portion
91
abuts on rear side surfaces
26
of the siding boards
2
disposed vertically. The support portion
92
is formed forward from the base plate portion
91
. The upper-board engagement portion
93
is formed to bend in a slant and upper direction from the support portion
92
. The lower-board engagement portion
94
is formed to bend in a slant and lower direction from the support portion
92
. In front of the upper-board engagement portion
93
and the lower-board engagement portion
94
, a front flat plate
934
is formed.
In addition, as shown in
FIG. 15
, the base plate portion
91
has a sloped portion
911
and a lower leg portion
912
. The sloped portion
911
is formed to be rearwardly slant at an upper portion of its own. The lower leg portion
912
is rearwardly bent at substantially 90 degrees at a lower end portion of its own.
In the siding boards attachment structure
8
, as an underlayment (for example, a sheathing board), a heat insulator
83
is fixed to the outside of the framework
3
such as a column as shown in FIG.
14
. From the outside of the heat insulator
83
, the furring strip
89
is fixed to the framework
3
via a waterproof paper
82
. In addition, in the outside of the furring strip
89
, the fastening member
9
is disposed and is fixed to the framework
3
with a screw
4
.
The fastening member
9
fixes the siding boards
2
in a manner in which the upper horizontal edge
21
of the lower siding board
2
is engaged with the lower-board engagement portion
94
, the upper siding board
2
is supported by the support portion
92
, and the lower horizontal edge
22
is engaged with the upper-board engagement portion
93
.
In the siding boards attachment structure
8
, since the furring strip
89
is disposed in the above-described manner, a ventilation space
81
having a sufficient thickness can be secured between the heat insulator
83
and the siding boards
2
. Thereby, ventilation characteristics are secured; and the components, such as the siding boards
2
, and the framework
3
, are prevented from being corroded and deteriorated because of water absorption. Thereby, the durability of the siding boards attachment structure
8
is improved.
However, the siding boards attachment structure
8
is still problematic in that the furring strip
89
needs to be installed, thereby increasing the processing time as well as material costs.
Specifically, when the siding boards attachment structure
8
is constructed, the furring strip
89
having regulated dimensions needs to be prepared, and in addition, a step is required for nailing the furring strip
89
to the framework
3
.
If the furring strip
89
is not used, by way of example, the siding boards attachment structure
80
will be obtained by disposing a heat insulator
84
in the outside of a framework
3
and fixing a fastening member
9
to a framework
3
from the outer side via a waterproof paper
82
and the heat insulator
84
, as shown in FIG.
16
A.
For the heat insulator
84
, a material, such as a stylofoam, a sheathing board, or an oriented strand board (OSB), is used.
As mentioned above, in the siding boards attachment structure
80
, since no furring strip is used, taking bend of the waterproof paper
82
into account, it can not be said that a ventilation space
81
is sufficiently secured.
In the siding boards attachment structure
80
, when a soft heat insulator
84
is used, the fastening member
9
is fixed on the surface thereof. Therefore, as shown in
FIG. 16B
, a case can occur in which the fastening member
9
is forced to be sunk into the heat insulator
84
, thereby disabling the fastening member
9
from being fixed in a stable state. Particularly, since the contact area of the lower leg portion
912
of the fastening member
9
and the heat insulator
84
is small, a defective case is likely to occur in which the lower leg portion
912
sinks in the heat insulator
84
, and consequently, the fastening member
9
leans forward and rearward.
As a result, as shown in
FIG. 16B
, the siding boards
2
fixed with the fastening member
9
is placed in an unstable condition. Therefore, substantially, it is difficult to achieve the fixing of the fastening member
9
to the framework
3
.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a siding boards attachment structure that is excellent in ventilation and that has a high structural strength for fixing siding boards, and a fastening member that is to be used with the aforementioned siding boards attachment structure.
According to a first aspect of the present invention, a fastening member disposed to span an upper horizontal edge of a lower siding board and a lower horizontal edge of an upper siding board for fixing the siding boards to a framework of a building, includes a base plate portion having a flat rear side surface, a support portion projecting forward from the base plate portion, an upper-board engagement portion bent upward from the support portion, a lower-board engagement portion bent downward from the support portion, and spacing portions individually formed at left and right sides of the base plate portion, each of the spacing portions has a front face which is forward from the base plate portion and rearward from the front end of the support portion.
The notable feature in the first aspect of the invention is that the fastening member has the base plate portion having the flat rear side surface, and the spacing portions formed at left and right sides of the base plate portion.
Hereinafter, operational advantages of the present invention will be described.
The siding boards can be fixed to the framework by using the fastening member in the manners described below.
The base plate portion of the fastening member is fixed to the framework such that the rear side surface of the base plate portion is directly set to abut on the framework or that the rear side surface of the base plate portion is fixed to the framework via a heat insulator. At this time, the lower-board engagement portion of the fastening member is set to engage with the upper horizontal edge of the lower siding board.
Subsequently, a construction is performed such that the lower horizontal edge of the upper siding board is set to be supported by the support portion of the fastening member and is engaged with upper board engagement portion. At this time, the rear side surfaces of the siding boards are set to abut on the spacing portions of the fastening member.
As described above, the fastening member has the spacing portions. The construction is therefore performed by setting the rear side surfaces of the siding boards to abut on the spacing portions. This manner enables a ventilation space to be formed behind the siding boards. That is, a
