摘要： A clamp for securement to a cylindrical body such as scaffold tubing has first and second curved body portions hinged to each other to form a generally circular enclosure. A clasp for coupling the first and second curved body portions has a bolt fixed to one curved body portion and a rotatable housing. The housing has a peripheral groove to slidingly receive the bolt and is coupled to the other curved body portion. The housing has an access opening to receive the bolt into the peripheral groove and the bolt is captured in the peripheral groove when the housing is rotated. The housing is rotatable about a post which is fixed to the other curved body portion and has an opening to receive the post that is eccentric to the geometric center of the housing so that a passage formed between the peripheral groove and the post varies in width about the periphery of the housing. This variable width allows the housing to be tightened gradually on the bolt.

摘要： The invention relates to a scaffold coupling element (1) with secure-sitting T-head bolts (10) ensuring permanent bracing of the scaffold elements (2) due to the fact that the T-head bolts (10) are fitted with shaped parts (20, 21, 22;24). Said shaped parts (22, 21, 22; 24) are configured to match the bell (26) of the retaining projecting part (11), wherein said parts ensure blocking while preserving the ability to pivot in the bell (26). Said parts are fitted with corresponding contact surfaces (27, 28) or cause blocking in said bell when the T-head bolts (10) are inserted in the bell (26). Said blocking can be further improved in a targeted manner in that the ends of the T-head (17, 18) are stepped starting from the back of the T-head (23) and forming a bevel (38), a short vertical (39) and a longitudinal bevel (40). Furthermore, the edges (42, 43) of the shaft (13) are fitted with chamfers (44, 45). The edges (42, 43) on the back of the T-head (23) enable the insertion of the scaffold element (2) once the T-head bolt (10) has been inserted. In addition to the changes in the T-head bolts (10), the bell (26) has been adapted to match the shape of the T-head (12), wherein both parts are embodied in such a way that they match each other.

摘要： rop scaffolding is formed by assemblies of drop tubes (12) and scaffold tubes (15) extending transversely between the drop tubes. Each drop tube has a top coupling secured to an upper part thereof and a bottom coupling secured to a lower part thereof, the two couplings being similar and having cradles with openings directed respectively generally downwardly and generally upwardly. Each coupling comprises an elongate body having a hollow section with a logitudinal axis extending the length of the body, in which section a drop tube is secured. A hook-like cradle (14b, 14c, 14d) projects from the body away from the hollow section with an opening (x) between retaining walls (14c, 14d,) each making an acute angle with the longitudinal axis of the section in the quadrant that includes the first end of the body. The cradle can receive a second scaffolding tube and releasable locking means (16) is movable between an open position allowing insertion of the second scaffolding tube into the cradle and a locking position wherein the second scaffolding tube is locked in the cradle.
The drop scaffolding is erected by forming a trapeze-like structure of two parallel drop tubes and a lower scaffold tube releasably secured in cradles of two bottom couplings. The structure is suspended from a top transverse tube by hooking top couplings secured to the drop tubes over the top transverse tube and thereafter releasably securing the couplings to the top transverse tube.

摘要： A mechanical coupling arrangement for a scaffold is provided. The mechanical coupling arrangement comprises a pole and a mounting collar having attachment means to which elongated support members can be attached. A level of radial play between said pole and said mounting collar in a first relative angular position is larger than the level of radial play between said pole and said mounting collar in a second relative angular position. The second relative angular position corresponds to a fastening position of said mounting collar, and in that said first relative angular position corresponds to an axial sliding position of said mounting collar.
