摘要:
There is provided a structural tube (1) comprising a fibre reinforced polymer wherein the tube comprises a plurality of layers (21, 22, 23, 24, 25) of reinforcing fibres with the fibres of at least one layer having a different orientation to those of another layer. Also provided is a kit of structural tubes and a structural tube assembly.
摘要:
A scaffolding member (20) formed of reinforced plastic material with appropriate levels of strength and stiffness. The scaffolding member (20) has a gripping surface on the external periphery thereof, preferably although not exclusively formed by the application of a layer of sand (34). A method of forming the scaffolding member (20) is also described. A scaffolding member (20) includes a substrate layer (22) having one or more protrusions (24). An outer layer (26, 28 or 32) is adhered to the substrate layer to form one or more nodes (40) at the external periphery by the presence of the one or more protrusions (24). A structural member (20) may be formed of reinforced plastics material wound to define one or more nodes (40) at the external periphery thereof.
摘要:
Die Erfindung betrifft einen Schwerlast-Gerüstturm (10) mit vier jeweils in einem Eckbereich (14a) des Schwerlast-Gerüstturms (10) angeordneten mehrteiligen Gerüstständerbündeln (16), die jeweils In Umfangsrichtung des Gerüstturms (16) über erste Horizontalriegel (20) und Vertikaldiagonalen (22) miteinander verkettet sind. Die Gerüstständerbündel (16) umfassen jeweils vier in seinen Eckbereichen (14b) angeordnete Gerüststieleinheiten (24), die zur Vertikalachse (12) des Gerüstturms (10) jeweils parallel verlaufend angeordnet sind und welche jeweils mehrere ineinandergesteckte Gerüststiele (28) mit Gerüstrosetten (30) umfassen. Zwischen den Gerüststieleinheiten (24) sind jeweils mehrere Distanzplatten (46) angeordnet, über die die Gerüststieleinheiten (24) relativ zueinander auf Abstand gehalten sind. Die mehrteiligen Gerüstständerbündel (16) weisen mehrere zweite Horizontalriegel (64) auf, die in axialer Richtung voneinander beabstandet angeordnet sind, wobei die zweiten Horizontalriegel (64) jeweils auf und streng entlang der Längsachse eines der ersten Horizontalriegel (20) verlaufend angeordnet sind und jeweils in eine Gerüstrosette (30) zweier bezüglich der Längsmittelachse (26) der Gerüststieleinheit (24) diametral einander gegenüberliegend angeordneter Gerüststieleinheiten (24) eingreifen und diese lösbar und abstandsinvarlant miteinander verbinden. Die zweiten Horizontalriegel (64) sind in axialer Richtung relativ zueinander zumindest teilweise über Kreuz angeordnet.
摘要:
A structure comprising at least three bars (10, 20, 30) joined together in pairs (10, 20; 20, 30; 30, 10) by a flexible linkage (112, 123, 131), the linkages being interconnected by a common ring-shaped member (40) through which they extend. Each bar (10, 20, 30) comprises channels (11-14, 21-24, 31-34) for the linkages (112, 123, 131).

L'échafaudage de maçon comporte un plan de travail (4), recevant les matériaux tels que du mortier, et des tréteaux du type élévateur à hauteur réglable supportant au moins un transporteur ou rampe à rouleaux (14) situé derrière le maçon.
摘要:
Scaffolding comprising, a scaffold structure, assembled next to yet spaced from an adjacent face of a building structure with a gap therebetween, comprising a plurality of standards extending vertically adjacent the structure, horizontal ledgers extending between standards and tying the standards in a fixed interrelationship, and a platform supported from the standards and/or the ledgers thereby to be conferred a vertical support in a substantially horizontal disposition; and a guard, as a lateral extension to the platform, configured to hinge or otherwise articulate downwardly from the scaffold structure to bear onto the face of the building structure to at least partially span across the gap.
