The amide oligomer typically contains urea links, urethane links or both groups. Additionally, the foams may include one or more plasticizer, a non-functionalized resin, a surfactant, and/or a thickening agent or rheology modifier. The amide oligomer does not contain any isocyanate groups, and, as a result, there are no free isocyanate moieties generated during formation of the foam that may be potentially hazardous to workers installing the foam. The presence of the urethane segments on the oligomer permits for the generation of a polyurethane foam without the drawbacks of conventional polyurethane foams. The foams may be used to fill cavities, cracks, gaps and crevices, such as around windows and doors, and may also be used in flash and batt systems.

  • Patent number: 8603375
    Abstract: A new procedure for constructing cryogenic storage tanks involves erecting a freestanding metal liner. The liner is sized and configured to withstand the hydraulic forces the concrete wall of the tank being poured without the need for temporary stiffeners on the inside surface of lower portions of the liner. Lateral tension ties can be connected to anchor ties on an outward surface of the liner and used to tie the liner to outer formwork. These ties may be spaced up to about 2 m apart. Studs can also be provided on the outer surface of the liner, and a cylindrical ring of cryogenic steel can be integrated into the liner.

  • Patent number: 8484928
    Abstract: Method of producing a wall-floor reinforced concrete construction in which use is made of prefabricated permanent shuttering systems made up of a wall shuttering system (100) with two shuttering panels (101; 103) and a floor shuttering system (120) which comprises a base plate (123) with a multiplicity of individual longitudinal bars (121) next to one another which are each fastened by means of a multiplicity of stirrups (122) on the base plate (123) at a distance above the base plate in such a way that they come to lie in the lower region of the floor (171) to be produced. The connecting element between the wall and floor that is used is a coupling reinforcement (150) which, on one side, is fastened into the wall shuttering system (100) and, on the other side, to the individual longitudinal bars (121) of the floor shuttering system (120) which extend perpendicularly to the wall shuttering system (100).

  • Patent number: 8429876
    Abstract: A system for constructing building consisting of connected T-beams for walls and roof. To create the T shape the system uses blocks of rigid insulation as forming, which are embedded in the poured-in-place concrete. These blocks serve to insulate the structure. The final structure is a monolithic box where the foundation, (101, 102), and (103) is the lower face, walls are the vertical faces of the box, attached to the foundation by dowels (104) to the walls reinforcement part (105) and the roof (118, 119, 120), and (121) is the top. This results in a sturdy structure with integrated high insulation (111) and (122) in walls and roof. Metal nailers (123) with the polystyrene foam strips (124) can be embedded in the ends of the T-beam stems. These nailers ease the insertion of screws to wall and ceiling interiors, allowing the building interior to be finished with gypsum board or paneling.
