WALL MATERIAL AND BUILDING STRUCTURE FROM WALL MATERIALS Russian patent published in 2024 - IPC E04F13/14 

FIELD: construction.

SUBSTANCE: invention relates to wall material, as well as to building structure containing such wall material. Technical result is achieved by the fact that wall material has a front surface and a rear surface opposite to the front surface, and comprises a front surface side connection portion located on one side in a first direction of the wall material, and a rear surface side connection portion located on the other side in a first direction, wherein the connection section on the side of the front surface has an expansion part on the side of the front surface, located on the side of the front surface of the wall material, a first end surface formed on the end part of the expansion part on the side of the front surface on one side in a first direction, extending in a direction from the front surface to the rear surface, a first expansion surface formed in the expansion portion on the front surface side facing the rear surface, extending to the other side in the first direction, and a first fixed portion formed on the side of the rear surface of the wall material, located in a portion offset from the first end surface to the other side in a first direction, wherein the connection portion on the side of the rear surface has a second end surface formed on the end portion of the wall material on the other side in a first direction, extending in a direction from the front surface to the rear surface, an expansion part on the side of the rear surface, located on the side of the rear surface of the wall material, extending from the second end surface to the other side in a first direction, a second expansion surface formed in the expansion part on the rear surface side facing said front surface, extending to the other side in the first direction, and a second fixed portion formed on the part of the end side of the expansion part from the side of the rear surface to the other side in the first direction, wherein the wall material further comprises at least one first resin film located on at least one of the first end surface and the second end surface, and at least one second resin film located on at least one of the first expansion surface and the second expansion surface, wherein no resin film is formed on first and second fixed sections, and the technical result is achieved by a building structure containing such a wall material.

EFFECT: creation of wall material with high water resistance.
