The male bead of one panel is adapted to be snapped into the female bead of an adjacent panel to lock adjacent panels together.
Abstract: A foundation for cellarless houses comprises a foundation wall (6) whose underside is disposed on a level below the ground surface (4) surrounding the house (1) and serves to support the house and, together with a bearing floor structure (5), also to define a bottom space (12) in the area above the ground on which the house is erected. The floor structure (5) has a lower portion which is air permeable in order, via the floor structure, to permit supplying air of substantially room temperature to said bottom space (12) from which the air is thereafter evacuated. According to the invention, said lower portion exclusively consists of a thin air-permeable web (11), and a heat insulating layer (21) for the foundation is placed directly on the ground (20) underneath the floor structure.
Abstract: The element comprises a socket and a bar slidingly insertable into the opening of the socket. Disposed around and spaced from both the socket and the bar are at least two closed loops each, of generally rectangular shape and made from reinforcing rods. The loops are secured to the socket and the bar, respectively, in one case by welding, in another case by means of a holder. Because they are symmetrically spaced from the socket and the bar, they ensure good distribution of pressure within the concrete.

Abstract: A sliding clip for a floating standing seam roof for allowing buckling of the roof panels to relieve excessive thermal expansion. The relative arrangement of the stops which limit the motion of the upper clip portion in respect of the lower clip portion is asymmetrical to allow a greater amplitude of motion of the upper clip portion toward the fixed ends of the roof panels caused by contraction than is permitted toward the floating ends of the roof panels caused by expansion. This prevents destruction of the clips or of the fasteners for the fixed ends. It also prevents rupture of the panels themselves at their fixed ends.
