摘要:
An airbeam includes at least a pair of inflatable beams each having an inner sleeve, middle sleeve and outer cover. Each sleeve is stitched to form flat side seams. The sleeves are inverted so that each flat side seam is disposed cantilevered inwardly on the inside of the sleeve. A linear common seam bisects the stitched side edges of the outer cover to form a pair of outer sleeves. One middle sleeve is nested within each outer sleeve. One inner sleeve is nested within each middle sleeve. One inner tube is nested in each inner sleeve. The nesting is arranged so that the side seams of the inner and middle sleeves are adjacent one another or overlap one another along, their entire length and so that the side seams of the outer cover are adjacent or overlap the side seams of the middle sleeve.

A collapsible structural member has been provided in which substantially identical modules made up of metal or plastic are threaded on a tensioning member such as a cable and are movable relative to each other in the collapsed condition of the beam and are brought together into a condition where adjacent modules are locked together to form a rigid construction when the beam is in its erected operating condition. The beam is changed from its erected condition to its collapsed condition by relaxing the tensioning member or cable.

A combination of a connector for glass elements and such glass elements to provide a loadbearing glass construc- tion that comprises at least one glass post and at least one glass beam that are arranged adjacent to each other, wherein the connector is arranged to provide a rotationally fixed connection between the post and the beam.
摘要:
A pultruded composite column (10, 110, 156) and beam (12, 130, 168) joint system is used in the construction of large structures and is particularly adapted for an electrical transmission tower because of the reduced EMF levels at ground level below the tower effected by the replacement of steel with composite members. The tower has corner legs or columns (10, 110, 156) which are interconnected and supported by a lattice structure of cross members (12, 130, 168). The columns (10, 110, 156) have one or more specialized longitudinal channels (14, 112, 158) spanning their lengths and the cross members (12, 130, 168) have specialized locking ends which lock into retaining structure defined in the column (10, 110, 156) channels (14, 112, 158), permitting cross member braces (12, 130, 168) to be inserted and locked in place at any selected point along the channel (14, 112, 158).
摘要:
L'invention concerne un élément composite à base de verre minéral. Le procédé selon l'invention consiste :
a) à découper dans une plaque de verre feuilletée, comprenant au moins deux feuilles de verre minéral séparées par une feuille de matière organique, deux, trois ou quatre éléments de verre dont la longueur représente au moins dix fois la largeur, b) à déposer sur au moins un des chants les plus longs d'au moins un de ces éléments une substance composée, au moins en partie, d'une matière organique identique à celle séparant les feuilles de verre desdits éléments, c) à appliquer ledit ou lesdits chants du ou desdits éléments sur au moins un autre élément, d) à soumettre l'ensemble ainsi assemblé à un traitement thermique et, éventuellement, à l'action simultanée, d'une pression supérieure à la pression atmosphérique.
Ces éléments sont utilisés aussi bien comme supports techniques que comme éléments architecturaux.
