  • Patent number: 6817150
    Abstract: A concrete form panel system includes a basic form panel of expanded polystyrene material having at least one slot formed in the top surface along its length, to divide the panel top surface into piers. A series of top hats are provided for selective attachment to the piers to increase the depth of the slots between piers, and thereby increase the depth of a joist formed by hardened concrete poured into the slot. Transverse slots may also be formed by separating top hats along their lengths. The transverse slots create transverse bracing between T-joists in a concrete deck. The form panels and top hats may also be used to create separate structural joists with attachment lifts, to permit connection of the joists to a subsequently constructed floor or deck system.

  • Patent number: 6401414
    Abstract: The use is described of rigid foam cores in panels, especially doors, of the kind comprising a foam core (22) between two molded skins (8,10). The weather-resistance, especially the resistance to thermally-induced bowing, of such panels is improved by forming the panel of at least one vacuum-formed thermoplastics skin (8,10) adhesively bonded to a substantially open-cell, rigid foam core (22). If the foam has frangible cell walls, it can be conformed to accommodate the depressed zones of a molded overlying door skin (8,10) by crumbling under compression, with fracture of the cell walls to accommodate the zones. A preferred open-cell rigid foam is a phenolic foam reinforced with finely divided particulate filler.

  • Patent number: 6360487
    Abstract: A resilient, insulated door panel for a sliding door includes a resilient core protected by a compliant outer covering with a seal disposed about the perimeter of the panel. The panel has sufficient resilience to recover from an impact that temporarily deforms it, yet has sufficient rigidity to transmit a compressive force needed for effectively setting the seals. Much of the core is filled with air to not only provide effective insulation and resilience, but to also provide an extremely lightweight door panel that can be operated to travel rapidly along an overhead track. Some embodiments include relatively rigid backup plates that provide a solid foundation to which the perimeter seals can be attached. The backup plates are segmented so as not to completely restrict the flexibility of the door panel.
