Patent number: 7448170Abstract: An indirectly prestressed concrete roof-ceiling construction is a prefabricated element for constructing large-span industrial buildings. The construction includes a distinctly wide and thin concrete soffit plate and an upper concrete girder of an inverse “V”-shaped cross section, interconnected by slender steel pipe-rods that are used to stabilize the upper girder against lateral buckling and to prevent the plate and the girder from getting closer or further away from each other. Prestressing of the soffit plate causes compression in the upper girder which passively (indirectly) pushes the ends of the construction, acting on some eccentricity over the center of gravity of the cross section, causing rotation of its ends, bending in that way the soffit plate upwards. There are two efficient methods of prestressing these constructions.Type: GrantFiled: November 19, 2002Date of Patent: November 11, 2008Assignee: Mara-Institut d.o.o.Inventors: Milovan Skend{hacek over (z)}ić, Branko {hacek over (S)}mr{hacek over (c)}ek

Patent number: 5701713Abstract: An adjustable truss is made up of a chain of truss elements sharing common edges. Pairs of adjacent elements are pivotally joined at their common edges, these shared edges acting as hinges. Tension cables are slidably received at the ends of each hinge. The truss can be erected by providing tensile forces in the tension cables. The precise angle of a specific hinge is controlled by actuators driving mechanical linkages connecting the adjacent truss elements associated with that hinge. The mechanical linkages serve to guide the amount of the forces from the cables which are applied to the hinge. In this way, the truss as a whole can be adjusted through an infinite range of configurational changes in three dimensions. The tension cables can be clamped at each hinge end, locking the selected hinge angles and pre-stressing the overall structure. In this way, the truss elements bear the compressive loads, while the cables bear the tensile loads.Type: GrantFiled: March 29, 1996Date of Patent: December 30, 1997Inventor: Daniel J. Silver

Patent number: 5291699Abstract: A roof includes a plurality of rafters each having at its upper end a connection and having at its lower end a fixing section, and a rod for retaining the rafters at predetermined intervals. The roof further includes a reinforcement material provided between the rafters, and an eaves trough extending along the periphery of the lower edge of the sheathing surface laid on the rafters. Accordingly, the labor hours required for, e.g., the positional change of the ridgepole or rafters when remodeling the conventional roof, are reduced, thereby enabling occupancy within the house under remodeling, as well as restraining the remodeling cost.Type: GrantFiled: December 15, 1992Date of Patent: March 8, 1994Inventor: Keiichi Fujita

Patent number: 5265394Abstract: An expandable-retractable portable structure is provided which is capable of being transported on public highways in its retracted position. The structure has a stationary portion and a movable portion, wherein the movable portion pivotally encloses the stationary portion of the structure in the retracted configuration of the structure. The movable portion of the structure carries a winch which when activated causes the movable portion to move from the expanded configuration to a retracted configuration by pivotally enclosing the stationary portion of the structure. The winch is reversed in direction to rotate the movable portion from the retracted to its expanded configuration wherein maximum interior space is available within the structure for use.Type: GrantFiled: November 17, 1992Date of Patent: November 30, 1993Assignee: X-SPAN-TEC CorporationInventor: Stewart E.

Patent number: 5142838Abstract: An improved standing seam roof assembly and support apparatus which seeks to achieve a number of objects including improved panel joining integrity both at the standing seam joints along longitudinal edges of the panels and at interlapping panel ends including the four corner juncture areas. A unique interlocking standing seam joint features cooperative clip and side lap sealant positioning. Advantageous end lapping is securely sealed via end lap sealant and a cinch strap assembly which compresses and interconnects the panel ends. Novel notching of the panel ends permits installation of near identical panels in both a first installing direction and in a reversed second installing direction. Other features include adjustable and flexible roof panel supporting structures, improved panel center and edge hold-down assemblies, and an improved seam roller apparatus.Type: GrantFiled: September 1, 1989Date of Patent: September 1, 1992Assignee: Harold Simpson, Inc.Inventors: Harold G.

Patent number: 4872297Abstract: Apparatus for adjustably attaching roof panels to the side walls of an enclosure and for securing the pitch of the roof panel with respect to the side walls after it has been established is disclosed. The apparatus includes a header support member which is placed on top of the side wall and has a longitudinally extending pocket therein. A header arm having a longitudinally extending yoke at one end thereof is received in the longitudinally extending pocket in the header support member. After the roof pitch has been established by rotating the yoke portion of the header arm within the pocket in the header support member, the header arm is fastened to the header support member to secure the roof pitch.Type: GrantFiled: September 30, 1988Date of Patent: October 10, 1989Assignee: Patio Enclosures, Inc.Inventors: Joseph R. Hetzel, Kenneth L. Virgins
