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: A scaffold system has a plurality of vertical members (10) and a plurality of cross members (12, 14) connected by couplings (18). The vertical members and cross members are comprised of polymeric matrix reinforced with glass and polymeric fibres. Each coupling (18) comprises a pair of annular flanges (54a, 54b), positioned on the vertical members in a spaced apart relation to form a groove. Each flange is formed with at least one aperture (56a, 56b) to accept a lock pin (66) which extends across the groove. In use, the lock pin (66) locks an adapted end (80) of a cross member in the groove by extending through the apertures of the flanges and an aperture in the adapted end (80) of the cross member.

摘要: The invention relates to a scaffold cross-bar (20) of metal with a round-tube carrier profile (21) of steel, consisting of a round tube and having an outside diameter (28), and a U-shaped reinforcing profile (22) of steel sheet. The U-shaped reinforcing profile (22) has a base profile (49) and two parallel profile legs (50.1, 50.2) which extend away from the base profile (49) in the same direction at a transverse spacing (52) from one another. Each profile leg (50.1, 50.2) has at least one opening (60.1, 60.2) for fastening and/or securing scaffold components on the scaffold cross-bar (20). The transverse spacing (52) of the profile legs (50.1, 50.2) is smaller than 0.6 times the outside diameter (28) of the round-tube carrier profile (21).

摘要: The invention concerns a metal scaffold bar (20.1) with a steel beam profile (21.1) comprising two beam profile ends (32.1, 32.2) that extend away from one another and to which a metal fastening means (33.1) is welded for detachably fastening the scaffold bar (20.1) to other scaffold parts (41). A U-shaped reinforcement profile (22.1) made of sheet steel is welded to the beam profile (21.1) using the fastening ends of the side branches of the U-shaped profile. The height of the U-shaped reinforcement profile is greater than the height of the beam profile and the width of the U-shaped reinforcement profile is smaller than the width of the beam profile by more than double the thickness of the beam profile (21.1).

摘要: A scaffold upon which a person stands includes a platform with a first leg assembly rotatably attached to the platform. The scaffold includes a latch assembly having a latch pivot axis coupled to the platform. The scaffold includes a stud attached to a first leg of the first leg assembly to which the latch assembly engages when the first leg assembly is moved into the extended position to automatically lock the first leg assembly in the extended position where the latch assembly is in a set position. When the latch assembly is moved out of the set position, the stud on the first leg disengages from the latch assembly and the first leg assembly is able to rotate about the first leg assembly pivot axis to a folded position. A method for using a scaffold.
