摘要:
Die Erfindung betrifft ein Tragsystem mit einem oder mehreren Fachwerkträgern (1, 2, 3), die jeweils Haupttragteile (5) und diese verbindende Tragelemente (27, 28) aufweisen, die Stäbe (28) aufweisen oder durch Stäbe gebildet sind. Damit ein derartiges Tragsystem aus weitgehend standardisierten Bauteilen im Baukastensystem geschaffen werden kann, wird erfindungsgemäß vorgeschlagen, daß das jeweilige Haupttragteil (5) als Strangpreßprofil ausgebildet ist, das mit mindestens einer in dessen Längsrichtung verlaufenden Führungsschiene ausgebildet ist, die der Aufnahme von komplementär gestalteten Enden der Tragelemente dienen, wobei jedes Tragelementende Befestigungsmittel zum Verbinden des Tragelementes mit dem zugeordneten Haupttragteil aufweist.
摘要:
Interconnecting apparatus (10) for a pair of structural members or space frame assemblies which avoids complex connectors while preserving its strength and capability of preventing disconnection. Apparatus (10) includes a button (12) attached to and end of one structural member and a receiver (18) attached to the end of another structural member. Receiver (18) includes a cradle (38) with a wall (40) on one side and a lip (42) on the other. Button (12) fits snugly into cradle (38) between wall (40) and lip (42) and is retained thereby a locking mechanism, such as clip (24). Interconnect mechanism (10) may be used in a variety of applications including connecting a pair of trusses together and creating a space frame structure.
摘要:
A support for electrical devices particularly electric lights comprising a plurality of members secured together to form a frame wherein at least one of the members (2) is hollow and a wall forming part of the member is provided with an opening (6) extending longitudinally of its length and means (7) for example a lid, for securing the wiring within the hollow member.
摘要:
On fabrique d'abord une carcasse (1) en disposant un ensemble d'organes oblongs (4) en un matériau composite autour d'un ensemble d'entretoises (2). On enroule ensuite un ensemble de câbles tendus (5, 5') autour de la carcasse (1) de sorte que chaque organe ablong (4) entre en contact avec un des câbles (5, 5') dans le plan de chaque entretoise (2). On fait ensuite adhérer les câbles (5, 5') à la carcasse (1), de préférence en faisant fondre le revêtement thermoplastique des câbles (5, 5') et en le laissant se solidifier. La poutre ainsi produite est légère et résistante.
摘要:
A master fining is disclosed adapted to be subdivided into a set of vertex fittings for use in a truss structure which comprises a plurality of frame elements. Interchangeable vertex fittings with accurately aligned surfaces, slots and holes are provided at a low cost. The vertex fittings are adapted to form the frame elements with mating struts, or to form hinge joints for interconnecting groups of frame elements. The invention permits ease of assembly and quick and easy removal and replacement of a strut in the truss structure.

A rotary joint (10) includes socket rod (2) having a socket rod flange (5) with an at least partly spheroid concave bearing surface (5a) at a first end, a housing nut (1) encircling the socket rod (2) and having a threaded wrenching head (1a), and a ball rod (13) having an at least partly spheroid convex bearing surface (13a) and threaded side walls (13b) around the bearing surface (13a). The diameter of the threaded side walls (13b) of the ball rod (13) corresponds to a diameter of the threaded wrenching head (1a) of the housing nut (1).
摘要:
A strut linkage (9, 30, 40, 50) for a steel construction (1), in particular of a tower of a wind power plant (2), preferably a corner post (3) of a lattice tower, is described and shown. In order that high forces can be dissipated via the strut linkage, without this entailing elevated stress peaks, an excessive use of material and/or an excessive outlay on construction, it is provided that a plate element (13, 31, 41, 51) is provided for arranging between (preferably load-bearing) steel construction components (7, 8), and that at least one connector element (17, 32, 42, 56) which is connected to the plate element (13, 31, 41, 51) is provided for attaching at least one strut (20) and/or guy of the steel construction (1) to the steel construction components (7, 8) via the plate element (13, 31, 41, 51).
摘要:
A structural frame includes a plurality of members formed from fibre reinforced polymer. A pair of the members are arranged to engage one another at a first joint. The joint includes a notch that is provided in an outer surface of the first member of the pair of members and which is arranged to receive an end portion of the second member of the pair of members.
摘要:
A rotary joint (10) comprises a socket rod (2) having a socket rod flange (5) with a basically spheroid concave bearing surface (5a) at a first end, a housing nut encircling the socket rod (2) and having a threaded wrenching head, and a ball rod (6) having a basically spheroid convex bearing surface (6a) and threaded side walls (6c) around the bearing surface (6a). A diameter of the threaded side walls (6c) of the ball rod (6) corresponds to a diameter of the threaded wrenching head of the housing nut. A plurality of first guiding tracks (5b) are arranged on the concave bearing surface (5a) and are oriented into a first swivelling direction (S1), the socket rod (2) being swivable with respect to the ball rod (6) along the first guiding tracks (5b) into the first swivelling direction (S1). A plurality of second guiding tracks (6b) are arranged on the convex bearing surface (6a) and are oriented into a second swivelling direction (S2), the socket rod (2) being swivable with respect to the ball rod (6) along the second guiding tracks (6b) into the second swivelling direction (S2).
