  • Patent number: 6898913
    Abstract: The invention relates to a locking system for mechanical joining of floorboards (1, 1?) which have a body (30), a lower balancing layer (34) and an upper surface layer (32). A strip (6) is integrally formed with the body (30) of the floorboard (1) and extends under an adjoining floorboard (1?). The strip (6) has a locking element (8), which engages a looking groove (14) in the underside of the adjoining floorboard (1?) and forms a horizontal joint. A tongue (38) and a tongue groove (36) form a vertical joint between upper and lower plane-parallel contact surfaces (43, 45) and are designed in such manner that the lower contact surfaces (45) are on a level between the upper side of the locking element (8) and a plane containing the underside (3) of the floorboard. The invention also relates to a floorboard having such a locking system, a floor made of such floorboards, as well as a method for making such a locking system.

  • Patent number: 6804916
    Abstract: A system and process for sealing exterior windows and doors of a building. For sealing a window, four slots are formed in the building wall spaced from the window. Four panels of material are obtained each having an elongated planar portion with two spaced apart edges and two flanges extending in opposite direction from the two edges respectively. One of each of the flanges of the panels are located in the four slots respectively and each of the other flanges are located next to the window. The lower ends of the two side panels overlap the laterally extending ends of the two side panels, and the upper panel overlaps the upper extending ends of the two side panels. The invention also is applicable to door frames in which case the lower panel will not be employed.

  • Patent number: 6792722
    Abstract: This invention relates to an Air handling unit casing in which the circulated air is thermally conditioned and prevents the change of the thermal condition of the circulated air due to air leakage and thermal bridge. It has a modular structure which can be disassembled in the case of the necessity and is constructed from panels (1) which are made of an inner skin (15), an outer skin (16) and insulation material (9) therebetween, doors (2) and door frames (3). The embodiment of the panels (1) does not allow the direct contact of the inner and outer skin and reduces the thermal bridge and air leakage through the unit by employing gaskets (8, 11, 17), plastic bushing (18) and heat barrier slits (28). The panels (1) can be joined to each other side by side or perpendicularly.

  • Patent number: 6792727
    Abstract: The invention comprises a system for constructing a finished convex or concave curved wall of any desired radius beyond a specified minimum. The wall is constructed of pre-finished rectangular panels retained on a sub-wall structure in horizontal rows and vertical columns. The panels are retained on the sub-wall structure with vertical rails at their vertical edges and retainer clips spaced along their horizontal edges. The panels are slotted at their rear face to provide rigidity in the vertical direction and flexibility in the horizontal direction. The horizontal edges of the panels are kerfed to receive the retainer clips and flexible splice strips that conform to the curvature of the wall and align and space a panel with the panel immediately above it. Clips attaching vertical edges of the panels to the rails allow the associated areas of the panels to align tangentially with the curvature of the wall.

  • Patent number: 6782665
    Abstract: In a dock unit for maintenance of aircraft there is provided, in addition to an outer support which supportingly engages against a frame disposed parallel to the longitudinal axis of the aircraft in the vicinity of the end of said frame and is adjustable, a further support which is located further in and is likewise adjustable.

  • Patent number: 6769221
    Abstract: A stairway system is disclosed that includes a plurality of spaced apart treads; a handrail; and at least two balusters per tread. Each baluster includes a top length segment, a bottom length segment and a turning length segment, the turning length segment including a portion of defined features. According to the present invention, a length of the turning length segment of a subsequent baluster is greater than a length of the turning length segment of a previous baluster on the same tread according to the equation of the riser height divided by the total number of balusters. Thus, each of a portion of the defined feature in the bottom length segment of each of the balusters align with the tread for each baluster. In the preferred embodiment, only four different baluster lengths are necessary for both two and three balusters per tread stairway systems.

  • Patent number: 6763636
    Abstract: An apparatus and a method are provided for lifting and leveling an existing building. At least a first non-cylindrical support section having a substantially rectangular shape and a second support section are coupled together by a fastening device that provides the apparatus with stability once the apparatus has been installed. A jack is used to raise the foundation of the existing building to a desired height. The apparatus is attached to the foundation of the building from underneath the building or from a location adjacent a side of the building. The non-cylindrical support section has low bearing and high friction characteristics. The low bearing characteristics enable the apparatus to be driven further into the earth than cylindrical pilings that are commonly used to lift and level existing buildings. The high friction characteristics assist in maintaining the stability of the apparatus once it has been installed.

  • Patent number: 6761009
    Abstract: The present invention relates to a method for manufacturing studs (9) or the like generally oblong pieces comprising a central web (14) and opposite flanges (8a, 8b) connected thereto. The present invention also relates to a stud system comprising such studs, as well as to methods for attaching such studs between an upper and a lower surface. Said flanges (8a, 8b) are formed of an essentially latch-like waste wood material which has been generated in mechanical wood processing, whereby a contact surface (13) is formed at the side of a respective opposite flange latch (8a, 8b) for co-operation with a surface (13a) shaped in a corresponding manner at a web (14) which also is made of wood, suitably of said waste wood material. Said contact surfaces (13, 13a) are glued, favorably under press, together so that said web (14) and said flanges (8a, 8b) attached thereto form an essentially monolithic entity.

  • Patent number: 6758015
    Abstract: The present invention relates to a modular screening assembly for a piece of equipment on the roof of a building. The assembly includes two perpendicular sets of channels that are rigidly secured to and cantilevered from a base of the equipment. Each channel set has one or two sets of common ends. A vertically oriented framework formed by a number of frame sections is secured to the common ends. Each frame section is secured to one set of common ends and spaced a uniform distance from the equipment. Each frame section is formed by one or more like-shaped frame segments. Each frame segment holds one like-shaped panel. Two or more modular screening assemblies can be combined to form an integrated screening assembly around several pieces of equipment. Two or more tiers of framework and panels can be stacked vertically to attain a desired screening height.

  • Patent number: 6755003
    Abstract: A construction beam includes a pair of lateral members and a resilient web extending therebetween, so as to present a cross-sectional profile corresponding to commonly used construction beam members. The resilience of the web helps to attenuate sound transmission through the beam from one lateral member to the other. Ends of the resilient web are fixed to respective ones of the lateral members on opposite sides of an imaginary reference plane passing orthogonally through both of the lateral members. In particular, in a wall frame, the lateral members are mounted at opposite ends thereof to end plates consisting of other construction beams according to the present invention. When used in a frame of a building structure, the lateral members of the end plates on the same side are attached to the surrounding structure, leaving the other side of the frame resiliently free floating.
