20090173577 | WORKING PLATFORM - The invention concerns a working platform assembly for use in the interior of a tower-like building. The object of the present invention is to provide a working platform assembly which can be used in the interior of a tower-like building even if the tower is closed at the top by an upper structure thereon. According to the invention that object is attained by a scissor lattice-like carrier structure and a working platform arranged on the carrier structure. In that respect the invention is based on the that the working platform assembly according to the invention can be adapted to different inside diameters of the tower-like building by virtue of the scissor lattice-like carrier structure and can thus extend completely across the tower cross-section. That makes it possible to work on the platform assembly. The working platform assembly can be released from the tower wall by the scissor lattice-like carrier structure and fixed again in another region of the building of a different cross-section. | 07-09-2009 |
20090236180 | Manhole construction safety and work platform device - The invention is a manhole construction safety and work platform device having a scaffold catwalk for working on a manhole, providing the safety and work platform with adjustable braces engaging the side of a conical manhole casing. The inner perimeter of the device circumferentially defines a central access opening in order to slidably accept, receive, and fit around the conical section of the manhole casing, as typically used in the utility construction industry. The scaffold catwalk has a safety barrier means on the working surface to provide a safe working environment along the outer perimeter. As is common in the industry, the conical section of the manhole casing may be an asymmetrical conical section. One objective of the present invention is to provide a scaffolding platform supported with at least three adjustable brace members to securely support the said platform against the sidewall of any shape of manhole casing. | 09-24-2009 |
20100000822 | SCAFFOLDING SYSTEM - A scaffolding system comprising a plurality of elongate structural tubes and a plurality of node members. Each node member has three or more mating portions that each extend along one of three mutually perpendicular axes that pass through the respective node member. End portions of the structural tubes can be releasably secured to the mating portions to provide a framework of vertical columns that extend between pairs of node members and horizontal beams that extend between pairs of node members. The scaffolding system further comprises a plurality of tie members that can each be releasably secured at opposing ends to a node member such that the respective tie member is inclined relative to the vertical columns or the horizontal beams, such that the scaffolding system, when assembled, is capable of supporting structural loads. | 01-07-2010 |
20100288583 | Founding system - A founding chair for a founding ladder system is of a lightweight fabricated design and includes a pivotally secured top leveling plate. A ladder system for the founding chair includes a slide in engagement rack for securing of the founding chair and allowing incremental adjustment. | 11-18-2010 |
20120037452 | VERTICAL ENCLOSURE SAFETY APPARATUS - A safety apparatus adapted for retrofitting vertical enclosures is shown. The safety apparatus may include a support frame, a grate platform, and telescoping support legs adapted to fasten to an enclosure wall. The apparatus may also include a hinged hatch defining an opening configured to allow a person to be pulled through the platform. | 02-16-2012 |
20140069740 | CONSTRUCTION APPARATUS - A construction apparatus for use within an elevator hoistway is provided. The construction apparatus includes span members, each span member having a first end, a second end and a length. Sill attachments are connected to the first end of the span members. The sill attachments are configured to rotate about and seat against a building sill. A support member connected to the second end of the span members. The support members are configured to seat against a second side of the elevator hoistway. The length of the span members is longer than a horizontal distance from the building sill to the second side of the elevator hoistway such that the span members rest in an inclined orientation with respect to a substantially horizontal axis. One or more platforms is supported by one or more forms, the platforms arranged such as to provide a working platform within the elevator hoistway. | 03-13-2014 |
20150068840 | PLATFORM FOR ACCESSING A HYDRAULIC MACHINE AND METHODS FOR INSTALLING AND DISASSEMBLING SUCH A PLATFORM IN A SUCTION TUBE - This platform provides access to a hydraulic machine via a suction tube. This hydraulic machine belongs to an installation for converting hydraulic energy into mechanical or electrical energy, or reciprocally. The platform includes a load-bearing element designed to slide along a longitudinal axis in order to enter an opening in the suction tube, said load-bearing element having an extremity that is designed to be immobilized in the suction tube and floor elements that are placed on the load-bearing element. At least some of the floor elements are articulated with the load-bearing element about axes substantially parallel to the longitudinal axis, while these floor elements can be rotated about these axes between a folded configuration and a deployed configuration and define at least a portion of a floor of the platform. | 03-12-2015 |
20150292263 | Supply Frame for a Tower; Tower with a Supply Frame and Method for Erecting a Supply Frame in the Interior of a Tower - A supply frame for a tower, a wind turbine tower and related methods include use of annular or annular segment-shaped prefabricated concrete parts to support internal tower structures. Supply frame modules may form a self-supporting unit that can be attached in suspended fashion to an upper prefabricated concrete part of the tower. The supply frame may have a framework-like grid structure stabilized by traction forces from its own weight and live load. | 10-15-2015 |
20150376906 | COLLAPSIBLE STRUCTURE FOR VESSEL HAVING INTERIOR SLOPING WALL - A collapsible support structure for assembly inside a vessel having a downwardly and inwardly sloping interior wall includes a base frame including a plurality of pivotably-connected beams and a plurality of base foot modules mounted thereto. The base frame is movable between an expanded configuration for bracing the base foot modules against the vessel, and a collapsed configuration in which the base frame has a width smaller than that of the expanded configuration. The base frame is moved between the expanded and collapsed configurations by pivoting the plurality of beams. | 12-31-2015 |
