Abstract:
1. A wooden structural component for manufacture of a flat structure, comprising two rectangular base plates of roughly a same size, aligned substantially parallel to each other, maintained to define a cavity therebetween and overlapping each other in a projection normal to main surfaces of the base plates, two rectangular wall panels of roughly a same size, aligned approximately parallel to each other, which are fixed in a projection normal to main surfaces of the wall panels, each wall panel being mounted on an outer surface of one base plate, and which are approximately a same size or a slightly smaller size than the base plates, the base plates and the wall panels each have longitudinal edges which are aligned approximately horizontal and parallel to each other, and top edges being aligned approximately vertically and parallel to each other, each wall panel being mounted to a respective base plate in an offset manner such that a portion of the outer surfaces of the base plates is exposed to define tongue joints arranged approximately at right angles to each other, and the wall panels protrude over longitudinal edges of the base plates, and protrude over top edges of the base plates to expose a portion of an inner surface of the wall panels to define corresponding groove joints arranged approximately at right angles to each other, approximately as opposites of the tongue joints, elongated longitudinally-stretched supports arranged in a cavity approximately parallel to each other and to the top edges of the base plates, and arranged approximately perpendicular to the longitudinal edges of the base plates, and whose length is approximately the same as the length of the top edges of the base plates or wall panels on the side, the supports being arranged at equal distances from each other, and such that a first distance of a first support from the nearest top edge of the base plates directly joined to a first support, and a second distance of a last support to a nearest top edge of the base plate directly joined to the last support, complement each other, the supports feature a rectilinear mid-profile with a substantially right-angled cross section and form retaining walls between the base plates approximately at right angles thereto, which subdivide the cavity between the base plates into chambers of roughly equal size, the supports feature tongue joints along edge sides, which fit into approximately equal and opposite grooves on the inner surface of the base plates to form a form-fitting connection between the supports and the base plates, the supports being arranged offset in relation to the longitudinal edges of the base plates, with the tongue joints partially engaged in opposite grooves on the base plates, and the base plates located opposite each other partially joining each other, the supports include approximately equally long free end pieces with approximately equally long free tongue joints, which protrude over a first of two longitudinal front sides of the base plates located opposite each other, the longitudinal front sides each being delimited by two longitudinal edges of the base plates located nearest each other, and the grooves include free end pieces in the base plates which are accessible from a second of the two longitudinal front sides and which are dedicated to incorporating the tongue joint of one of the free end pieces of a neighboring wooden structural component of a same kind on the flat structure.
