A building face material with printed indications is provided, where, even when any part of the building face material is cut in a cutting process in a manufacturing process, each first printed indication is marked at an allowable distance from an end side of the building face material that is rectangular in a plan view, and printed indications are preliminarily marked at predetermined intervals, in a given column.

The building face material 10 with printed indications includes printed indication strings each including one string group that is repeated in cycles, the string group being formed, in a plan view, on a rectangular flat face of the building face material, and the strip group consisting of multiple printed indications that are arranged, at regular first intervals, in a predetermined order along at least one straight line driven to a first side 11 or a second side 12 of a rectangle.

A wall element including upper and lower elements at upper and lower edges. A first side element extending along the first side, a second side element extending along the second side and a substantially rectangular board are present. The upper and lower elements include a first edge coinciding with the first side and a second edge coinciding with the second side, wherein the first and second edges are arranged in an angle with respect to a plane perpendicular to the outer surface, the angle lies within the interval 20°-45°, and the first and second side elements extending parallel to the plane, perpendicular to the board and having a total extension corresponding to the extension of the upper and the lower element in the plane, wherein the first side element bear against the plate and the second side element extend from the inside of the wall element.

A building-construction panel includes a tongue on one edge and a groove on an opposite edge that receives the tongue of an adjacent panel. A shoulder on the tongue-side edge defines an abutted surface that is contacted by an abutting surface on the groove-side edge to limit panel travel during installation and maintain a gap between upper edge portions of the adjacent panels. A bottom transition is formed on the groove-side edge so that the groove-side abutting surface is smaller than the tongue-side shoulder abutted surface. In this way, the relatively smaller groove-side abutting surface structurally maintains the gap but also minimizes frictional interpanel contact area to minimize squeaking. And the relatively larger tongue-side shoulder abutted surface helps keep the shoulder from being collapsed into the groove from overdriving the panels together during installation. In typical embodiments, the panel is a high-performance structural wood subflooring panel.

A foldable tubular construct/element with one rigid degree of freedom is of a tubular construction formed by a number of single layered annular units which are connected in sequence; each single layered annular unit is of a prism having N ridge lines; two adjacent prisms each having N sides are connected to each other by sharing a polygon with N sides formed on an intersection plane; each prism with N ridge lines is composed of N rigid planar quadrilateral facets; two adjacent single layered annular units comprise N spherical mechanisms formed by the intersections of only four planar quadrilateral facets at each apex; the polygon having N sides formed in the intersection plane of the two adjacent single layered annular units is a planar polygon with an arbitrary number of sides greater than for a triangle; the ridge lines of each prism having N ridge lines are parallel to each other; the connecting ridge lines of the tubular element are coplanar; when the polygon having N sides formed in the intersection plane of the two adjacent single layered annular units is a line-symmetric polygon of even number of sides with at least one diagonal symmetric axis, the plane in which connecting ridge lines of the tubular element are located is perpendicular to one diagonally symmetric axis.

A vacuum insulated panel (VIP) and a method of manufacturing a VIP includes a rigid core material having high insulation and low conductivity properties. The rigid core may be made of an inorganic material that effectively mimics a porous silica core material. The core material includes large particles of an inorganic material having a diameter in a range of 10 μm to 50 μm. A portion of these large particles may be ground into small particles having a diameter of less than 1 μm. The small particles are mixed with a portion of the large particles to form a core material which is then mixed with a fiber skeleton and compacted under vacuum along with a fibrous skeleton for structure. The resulting structure provides a porosity ranging from 10 nm to 1 μm in diameter.
