Abstract

[Object] To provide a wall material and a wall-material building structure that are suitable for achieving high water resistance in the wall-material building structure. [Solution] A wall material X of the present invention has a surface-side joint portion 10 and a rear-side joint portion 20. A first resin film 31 is provided on at least one of an end surface 11a of the surface-side joint portion 10 and an end surface 21 of the rear-side joint portion 20. A second resin film 32 is provided on at least one of an extension surface 11b and an extension surface 22b. At a splice part where the surface-side joint portion 10 of one wall material X and the rear-side joint portion 20 of another wall material X are spliced together in a first direction D1, the end surfaces 11a and 21 and the first resin film 31 are disposed such that the end surfaces 11a and 21 face each other while a gap between the end surfaces 11a and 21 is filled with at least the first resin film 31, and the extension surfaces 11b and 22b and the second resin film 32 are disposed such that the extension surfaces 11b and 22b face each other while a gap between the extension surfaces 11b and 22b is filled with at least the second resin film 32. A wall-material building structure Y of the present invention is formed by using such a wall material X.

A wall material that has a front surface and a rear surface opposite to the front surface, the wall material comprising:

a surface-side joint portion positioned in one side in a first direction of the wall material, and
a rear-side joint portion positioned in an other side in the first direction,
wherein the surface-side joint portion has:
a surface-side extension portion positioned in the front surface side of the wall material,
a first end surface formed in an end portion of the surface-side extension portion in the one side in the first direction, extended in the direction from the front surface toward the rear surface,
a first extension surface formed in the surface-side extension portion to face the rear surface, extended in the other side in the first direction, and
a first secured portion formed in the rear surface side of the wall material, positioned in a portion displaced from the first end surface in the other side in the first direction,
wherein the rear-side joint portion has:
a second end surface formed in an end portion of the wall material in the other side in the first direction, extended in the direction from the front surface toward the rear surface,
a rear-side extension portion positioned in the rear surface side of the wall material extended from the second end surface in the other side in the first direction,
a second extension surface formed in the rear-side extension portion to face the front surface, extended in the other side in the first direction, and
a second secured portion formed in an end side portion of the rear-side extension portion in the other side in the first direction,
wherein the wall material further comprises:
at least one first resin film positioned on at least one of the first end surface and the second end surface, and
at least one second resin film positioned on at least one of the first extension surface and the second extension surface,
wherein no resin film is positioned in the first secured portion and the second secured portion.
