摘要： The scaffolding assembly (300) comprising scaffolding (307, 309) for erecting a scaffold (303) for operable positioning at and/or against a portion of a construction and providing a work space for a worker, in particular an elevated work space, and a cover (305) for covering at least part of the work space. The scaffolding assembly (300) further comprises a roller device (317) for reversibly (un-)rolling a rollable portion (305R) of the cover (305) to (from) a rolled-up configuration from (to) an unrolled configuration for (un-)covering the at least part of the work space (W).

摘要： A method of manufacturing a tower structure includes printing and depositing, via a printhead assembly of an additive printing system, one or more printed layers of a wall of the tower structure. The method also includes unwinding at least one continuous roll of a reinforcement material to form at least one continuous reinforcement ring member layer, the reinforcement material comprising a pultruded polymer material. Further, the method includes placing the at least one continuous reinforcement ring member layer atop the one or more printed layers of the wall of the tower structure. Moreover, the method includes printing and depositing, via the printhead assembly of the additive printing system, one or more additional printed layers of the wall of the tower structure atop the at least one continuous reinforcement ring member layer.
