CROSS-REFERENCES TO RELATED APPLICATIONS
The present application claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2000-241603, filed on Aug. 9, 2000, entitled “EXTERNAL WALL CONSTRUCTION, SEALING FIXTURE, EXTERNAL WALL PANEL, AND EXTERNAL WALL CONSTRUCTING METHOD”. 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 an external wall construction for mounting an external wall panel on an underlayment using a securing metal fitting and further relates to a sealing fixture, an external wall panel, and an external wall constructing method used for the external wall construction.
2. Discussion of the Background
Conventionally, there has been known an external wall construction: wherein a securing metal fitting is engagingly locked to an upper underlying tongue portion formed at an upper side portion of an external wall panel disposed in a lower position and a lower overlying tongue portion formed at a lower side portion of an external wall panel disposed in a higher position, and vertical aligned external wall panels are fixed to an underlayment. In the external wall construction, an external wall panel having a four side (left, right, upper and lower sides) shiplap structure or a left-and-right side shiplap structure is used from the viewpoints of appearance design properties or constructing properties or the like.
For example, an external wall construction
9
using an external wall panel
92
having the four side shiplap structure shown in
FIG. 19
is shown in FIG.
20
. In
FIG. 20
, a front side surface of the external wall panel
92
arranged at an upper right position is indicated by a double-dot chain line.
As shown in
FIG. 19
, the external wall panel
92
has an upper underlying tongue portion
922
, a lower overlying tongue portion
921
, and a lateral underlying tongue portion
924
and a lateral overlying tongue portion
923
that are provided at a right side portion and at a left side portion, respectively. As shown in
FIG. 20
, during constructing, the lower overlying tongue portion
921
of the upper external wall panel
92
is superposed on the upper underlying tongue portion
922
of the lower external wall panel
92
, and the lateral overlying tongue portion
923
of the right external wall panel
92
is superposed on a lateral underlying tongue portion
924
of the left exterior wall panel
92
.
In addition, as shown in
FIG. 19
, a caulking material
929
is attached on the upper underlying tongue portion
922
and lateral underlying tongue portion
924
of the external wall panel
92
. Over this caulking material
929
, as shown in
FIG. 20
, the rear surfaces of the lower overlying tongue portion
921
and lateral overlying tongue portion
923
of another external wall panel
92
are pressed, thereby preventing water penetration into the external wall construction
9
from the joint clearance portion
927
of each external wall panel
92
.
In addition, in the external wall construction
9
with a four side shiplap, as shown in
FIG. 20
, the caulking material
929
is covered with the lower overlying tongue portion
921
and the lateral overlying tongue portion
923
, and is not exposed in front of the exterior wall. Therefore, an external wall construction with an excellent appearance design properties can be obtained.
In addition, in the external wall construction
9
, a securing metal fitting
5
(refer to
FIG. 5
) is installed at an upper underlying tongue portion
922
and a lower overlying tongue portion
921
of the external wall panel
92
, and each of the external wall panels
92
is fixed to an underlayment
3
such as a furring strip (refer to FIG.
6
). That is, a lower panel engaging portion
54
of the securing metal fitting
5
is engagingly locked with the upper underlying tongue portion
922
of the lower exterior wall panel
92
, the upper external wall panel
92
is supported by means of a support portion
52
, and the upper panel engaging portion
53
is engagingly locked with the lower overlying tongue portion
921
of the upper external wall panel
92
.
In addition, there is a problem that, although the caulking material
929
is attached on the external wall construction
9
, rainwater
6
or the like may penetrate into the construction.
As shown in
FIG. 20
, the rainwater
6
penetrating into the joint clearance portion
927
is inhibited from moving in a transverse direction (to the right side in
FIG. 20
) by means of the caulking material
929
, and drops downwardly through the joint clearance portion
927
. Then, the rainwater
6
drops further through the joint clearance portion
927
of the external wall panel
92
that is disposed downwardly.
However, the caulking material
929
applied to the lateral underlying tongue portion
924
of the external wall panel
92
is discontinuous at a rear surface joint clearance portion
928
between the upper and lower external wall panels
92
. Therefore, when the rainwater
6
dropping through the joint clearance portion
927
reaches the rear surface joint clearance portion
928
of the upper and lower external wall panel
92
, a part of the rainwater
6
may penetrate into the external wall construction
9
.
In addition, as shown in
FIG. 21
, in the case where the securing metal fitting
5
is arranged at the corner of the external wall panel
92
, the rainwater
6
dropping through the joint clearance portion
927
passes through a front face of a front flat plate
57
of the securing metal fitting
5
, and moves further to the joint clearance portion
927
that is disposed downwardly.
However, as shown in
FIG. 21
, there is apprehension that a part of the rainwater
6
flows transversely through the front face of the front flat plate
57
, drops from a side end
59
to the upper underlying tongue portion
922
of the lower external wall panel
92
, and further, penetrates into the rear side of the external wall panel
92
.
In addition, a part of the rainwater
6
moving transversely through the front flat plate
57
travels over the upper panel engaging portion
53
, moves onto the support portion
52
, and further, moves to the left and right side ends
59
. Then, this rainwater
6
also penetrates from the side end
59
of the securing metal fitting
5
to the rear side of the external wall panel
92
.
In this manner, the external wall panel
92
or underlayment
3
may be corroded or degraded.
The rainwater
6
penetrating from the joint clearance portion
926
between the upper and lower external wall panels
2
is inhibited from upward moving by the caulking material
929
in a transverse direction attached on the upper underlying tongue portion
922
, and is discharged forwardly as is (FIG.
21
).
SUMMARY OF THE INVENTION
An object of the present invention is to provide an external wall construction capable of inhibiting water penetration into the external wall construction reliably; and a sealing fixture, an external wall panel, and an external wall constructing method, which are used for the external wall construction.
According to one aspect of the present invention, an external wall construction includes a securing metal fitting installed at the upper side portion and the lower side portion of an external wall panel, and the external wall panel mounted on an underlayment, wherein:
the external wall panel includes a notched recess formed on a left side portion and a right side portion along the vertical direction;
a sealing fixture is arranged between the adjacent left and right external wall panels;
