A complex profile made of a composite comprising a polyolefin polymer and a wood fiber. The composite is useful in conventional structural applications. The profile can be used in residential and commercial structures. The profile is used in the manufacture of the fenestration components such as windows and doors. The profile is designed with a cross-sectional shape to form structural elements in the fenestration units that possess sufficient strength, thermal stability and weatherability. The member comprises a hollow cross-section with at least one structural web or one fastener web. The profile can have a visible capstock layer and can be assembled using thermal welding processes.

A prefabricated concrete panel for industrialized building, with high thermal and/or acoustic insulation, comprising a first sheet and a second sheet which are embedded in the concrete body of the panel and face each other on planes which are parallel to the planes of arrangement of the two larger faces of the panel. At least one of the sheets is made of thermally insulating material and the sheets delimit, therebetween, an air chamber which is divided into a plurality of mutually connected recesses in order to increase thermal and/or acoustic insulation of the panel.

An improved insulated glass including a spacer unit and a pair of glazing panels bonded to opposite sides thereof. The spacer unit includes a peripheral spacer portion and a muntin portion within the spacer portion. The spacer unit is a one-piece, injection-molded unit, and consequently the spacer portion and the muntin portion form an inseparable integrated whole.

A structural panel comprises a metal and fibrous composite in which the metal outer skins have a minimum thickness of 0.005 in. exceeding foils and a maximum thickness of 0.012 in. while the fibrous core ranges between 0.01 in. and 0.05 in. The panel is a stiff, lightweight substitute for thicker metals and may replace light metal sheets such as aluminum with a composite in which the metal skins comprise sheets from heavier metals such as steel. The fibrous core is a web which is adhesively bonded to the metal skins and which has a plurality of weight-reducing openings formed therein to form a structural laminate having comparable strength to steel sheets of greater weight.

Structural insulated panels having an inner insulating core and first and second outer facings disposed on opposed surfaces of the insulating core are securely attached to a structural member such as 2X stick structural members in a building structure. A strip of tape is wrapped around the structural member and opposed ends of the tape strip are adhesively bonded to the opposed outer facings of the panel. The tape strip may extend the full height or width of the panel to provide a secure, environmentally sealed connection between the panel and the structural member. An adhesive bonding agent may be inserted between an edge of the panel and the structural member to further increase the strength of the connection between the panel and structural member. The panel's edge may be provided with a C-shaped metal channel for more securely attaching the panel to the structural member by means of nails or screws driven through opposed ends of the tape strip and into the metal channel within the panel. The structural insulated panel is provided with smooth, continuous outer facings for improved bonding between the panel and the tape strip which is preferably a high strength, flexible, self-adhering structural tape. The tape connection arrangement may also be used to connect adjacent panels in an edge-to-edge abutting manner as well as in the installation of a narrow filler structural insulated panel disposed between adjacent 2X dimensional structural members.

Building element including of two parallel welded wire grid mats (1, 2), of straight web wires (7) which hold the wire grid mats at a predetermined distance apart and are joined at each end to the two wire grid mats, and of an insulating body (8) which is arranged between the wire grid mats and through which the web wires pass, wherein at least one of the wire grid mats is in the form of a grid reinforcement mat which possesses a minimum strength of the weld nodes which complies with the static requirements applicable to the building element, corresponding mechanical strength of the grid mat wires (3, 4) and also corresponding diameters and mutual spacings of the grid mat wires, and wherein the web wires are arranged in predetermined directions relative to the wire grid mats, and the insulating body is held at a predetermined distance from each of the wire grid mats.
摘要:
An improved composite structural member comprising a complex profile structural member, made of a composite comprising a polypropylene polymer and a wood fiber. The material is useful in conventional construction applications. The complex profile, in the form of an extruded thermoplastic composite member can be used in residential and commercial structures as described. Preferably, the structural member is used in the manufacture of the fenestration components such as windows and doors. Such linear members are designed with specifically configured cross-sectional shapes to form structural elements in the fenestration units. Structural elements must possess sufficient strength, thermal stability and weatherability to permit the manufacture of a structurally sound window unit that can be easily installed into a rough opening but can maintain its attractive appearance and structural integrity over the life of the window unit often twenty years or more. The structural member comprises a hollow complex cross-section with at least one structural web or one fastener web formed within the component. The exterior of the extruded component has a visible capstock layer and is shaped and adapted for installation in rough openings. The exterior also contains shape and components capable of supporting the elements of the fenestration unit such as a window, sash or movable door unit. The improved polypropylene structural members have unique advantages and can be assembled in thermoplastic weld processes.
