摘要:
A building system that includes a modular panel with side members, at least one of the side members having an associated coupling for hooked connection with a corresponding shaped fixture of an adjacent structure, the coupling and fixture being adapted to be held together by a locking device that, when engaged, acts to lock the structure and the side member together and, when disengaged, allows for play between the panel and structure in order to free the panel from the structure.
摘要:
The invention relates to supporting elements and to the connection elements thereof of an at least two-part shell, beam, or framework supporting structure (1), which is made of a metal material and in which fatigue is primarily relevant to the dimensions, for any application and in any geometry. The invention is characterized in that the supporting elements (2.1 to 2.n) of the complete structure or individual structure portions are pretensioned partially or all around on one or more planes on the inside or outside by means of tensioning elements (3.1 to 3.m) at a bracing angle (β) and/or by means of operating loads to such a degree that the stress of each individual supporting element under all expected operating loads, even under extreme loads, always occurs in the pulsating stress range according to the threshold tension ratio 1
摘要:
A structural element (10) for forming a panel, with an upper plane (12) and lower plane (14) which are parallel and deformed along their plane at intervals by pods (16) which extrude toward the opposing plane with their internal faces mating to one another.
摘要:
Eine Anordnung mit einer Tragkonstruktion (4), einem Abstandshalter und einer äußeren Fassadenschale (9) sieht vor, dass der Abstandshalter zwischen Tragkonstruktion und Fassadenschale einen Übergangsbereich mit reduziertem Wärmedurchgang aufweist. Derartige Abstandshalter können beispielsweise Z-Profile oder Kassetten sein, innerhalb denen Dämmmaterialien (12) angeordnet sind.
摘要:
According to one exemplary embodiment, the application relates to a method for manufacturing a thermal modification kiln for timber. The method comprises making plate modules from steel plates (200) by forming edges (210, 220, 230, 240) of the plates with flaps (211, 213, 215, 221, 223, 225, 231, 233, 235, 241, 243, 245), which enable adjacent modules to be interconnected for constructing a kiln frame.
摘要:
A system for providing one of heating and cooling in an indoor area is disclosed. The system includes one or more monolithic radiant panels. The one or more monolithic radiant panels include a tubular portion for circulating fluid. The circulation of fluid enables heating or cooling of the indoor area. The one or more monolithic radiant panels also include two co-planar fin portions that are arranged diametrically opposite to each other about a periphery of the tubular portion. Either one of the two co-planar fin portions are configured to be attached with a surface of the indoor area at an angle.
摘要:
The invention relates to a composite structural member with thermal and/or sound insulation characteristics for a building, comprising an insulating board shaped as web part and at least one protective element whereby the web part has two opposing abutting faces and two main surfaces being arranged rectangular to the abutting faces, whereby the board is made of mineral fibres and a binder and whereby the at least one protective element is substantially U-shaped in cross section, having two legs erecting parallel to each other and being connected to the web part, whereby abutting faces of at least one web parts are covered by protective elements, which in combination with said web part take up loads parallel and/or rectangular to the main surfaces of the web part and which are not in direct contact to each other.
摘要:
A prefabricated roof plate element (4), including one or more longitudinal box-shaped girders (24), each consisting of two predominantly U-shaped metal sections (10, 18) which at mutually facing, open sides are interconnected along narrow outwards bent lateral edges (5), the girders (24) being connected at upper and lower narrow sides corrugated in longitudinal direction with corrugated metal plates (7) corrugated in transverse direction and having approximately the same width as the roof plate element (4), the girders (24) being disposed along opposing sides and at the centre of the roof plate element (4), where the girders (4) and the roof plate element (4), respectively, are designed with reduced height/thickness at an end part intended for forming eaves (6). By means of simple technical measures is hereby achieved substantial projecting advantages which furthermore have appeared, to enable an architecturally very simple and light construction of the visible part of the roof plate on buildings.
