ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a joint member for a joint groove required to secure water-tightness between adjacent wall surface facing members in a building, and an installation method for the same.
2. Discussion of the Background
Hitherto, as a means for sealing a joint groove between adjacent wall surface facing members A of a siding or the like in a building, a hat-shaped joiner
50
shown in
FIG. 11
is fixed to a bed member
51
such as a furring strip, and a sealant
52
is charged in a joint groove formed by abutting the wall surface facing members A against both side surfaces
50
a
of a protuberance of the joiner
50
so as to enhance the water-tightness of the joint groove.
The conventional means for sealing a joint groove, however, requires that masking be provided before installation to prevent a sealant from adhering to the wall surface facing members A prior to charging the sealant
52
. The installation is not only cumbersome but also requires skill because the surface of the sealant
52
must be made as flat as possible in order not to ruin an appearance thereof. Furthermore, spots are produced in some cases when charging the sealant, so that sealing effect cannot always be enhanced.
SUMMARY OF THE INVENTION
A technological object of the present invention is to provide a joint member that can be easily installed, without adversely affecting an appearance, in a joint groove required to secure water-tightness between adjoining wall surface facing members of a building, and an installation method for the same.
Another technological object of the present invention is to provide a joint member and an installation method for the same that permit easy, reliable sealing in setting a predetermined joint groove between wall surface facings by using a joiner, by providing the joiner itself with a structure for enabling a joint groove to be easily sealed so as to obviate the need for masking or manual sealant charging.
To these ends, a first joint member in accordance with the present invention is comprised of: a joint base member consecutively and integrally installed on a surface of a synthetic resin joiner provided by being positioned between wall surface facing members on a bed surface of a building facing; wherein the joint base member has right and left side plates, at least two soft sealing tongue flaps protuberantly provided on outer side surfaces of the side plates, distal ends thereof being in contact with end surfaces of the wall surface facing members that constitute inner walls of a joint groove, and many apertures drilled between the sealing tongue flaps in the two side plates; a sealant of a sufficient amount to be pressed out and charged into a space to seal the space surrounded by the pair of sealing tongue flaps and the inner side walls of the joint groove is charged between the side plates of the joint base member; and a sealing member for restraining outflow of the sealant is attached to a mouth portion between the two side plates of the joint base member; and a core member to be pushed into a gap between the side plates of the joint base member is formed by a core portion that pushes into the gap between the side plates while pressing the covering member thereby to press the sealant, which has been charged therein, out through the apertures of the side plates, and a jaw plate of a head portion that covers a joint groove mouth portion, the core portion and the jaw plate being consecutively installed such that they are formed to have a substantially T-shaped section, and the core portion having a length that does not cause itself to reach a bottom part of a sealant charge area between the sides plates when it is pushed in.
Further, a second joint member in accordance with the present invention is comprised of: a joint base member consecutively and integrally installed on a surface of a synthetic resin joiner provided by being positioned between wall surface facing members on a bed surface of a building facing; wherein the joint base member has right and left side plates, at least two soft sealing tongue flaps protuberantly provided on outer side surfaces of the side plates, distal ends thereof being in contact with end surfaces of the wall surface facing members that constitute inner walls of a joint groove, and many apertures drilled between the sealing tongue flaps in the two side plates; a sealant of a sufficient amount to be pressed out and charged into a space to seal the space surrounded by the pair of sealing tongue flaps and the inner side walls of the joint groove is charged between the side plates of the joint base member; and a covering member for restraining outflow of the sealant and for restraining a mouth portion between the two side plates from narrowing is fitted into the mouth portion between the two side plates of the joint base member; and a core member to be pushed into a gap between the side plates of the joint base member is formed by a core portion that presses out the sealant, which has been charged by being pushed into the space between the side plates, out through the apertures of the side plates by pressing the covering member to push it into the gap between the side plates, and a jaw plate of a head portion that covers a joint groove mouth portion, the core portion and the jaw plate being consecutively installed so that they are formed to have a substantially T-shaped section, and the core portion having a length that does not cause a distal end of the covering member to reach a bottom part of a sealant charge area between the sides plates when the core portion is pushed in.
In the joint member, it is appropriate to form, between sealing tongue flaps on the joiner side in the side plates of the joint base member and the joiner, a space into which the remainder of the sealant, which is pressed into the space surrounded by the pair of sealing tongue flaps and the inner walls of the joint groove when the core member is pushed into a gap between the side plates, flows. Furthermore, it is preferable to form a protuberance for setting a minimum width of the joint groove on the proximal ends of at least one set of sealing tongue flaps at opposing positions of the two side plates, the protuberance being located on outer side surfaces of the two side plates in the joint base member.
Furthermore, an installation method in accordance with the present invention employing the aforesaid joint member is comprised of: a step for providing a joiner by positioning a joint base member between wall surface facing members on a bed surface of a building facing; and a step for pushing a core portion of a core member into a gap between side plates of the joint base member filled with a sealant, or pushing in the core portion of the core member while pushing a covering member, which has been fitted into a mouth portion between the two side plates of the joint base member, to push the sealant out through apertures in the side plates into a space surrounded by a pair of sealing tongue flaps protuberantly provided on the outer side surfaces of the side plates and inner walls of a joint groove, and covering a mouth portion of the joint groove by a jaw plate of a core member head portion at the same time.
Furthermore, a third joint member in accordance with the present invention is comprised of: a sealing structural member integrally and consecutively installed on a surface of a synthetic resin joiner provided and positioned between wall surface facing members on a bed surface of a building facing; wherein the sealing structural member has flexible right and left side plates and soft sealing flaps protuberantly provided on outer side surfaces of the side plates; a core member pushed into a gap between the side plates of the sealing structural member is formed by a core portion that is pushed into a gap between the side plates to push and spread the two side plates to press the sealing flaps on outer side surfaces of the side plates into contact with inner walls of a joint groove, and a jaw plate
