    摘要： Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.

    摘要： Articulated dismountable modular scaffolding of the type assembled at the workplace by means of parts comprising a structure that can be assembled and disassembled, characterised by the fact it is made up by the following interconnected parts: Vertical Tubes (1), Joints (N). The joints (N) are the points where vertical [bars] converge with horizontal or diagonal ones, being formed by two symmetrical, semi-circular semi-joints. Horizontal Tubes (6), The horizontal fastening (H) has a catch (9) in its lower part, as a latch (9) Diagonal Tubes (21), Diagonal Fastenings (D), located at each end of the diagonal tube (21),

    摘要： An attachment device comprises a conical screw and a hook which fits thereto with a curved center portion having a slot extending in the length direction of the hook. A plate can be engaged in said slot so that an aperture in the plate located near the edge thereof partly reaches inside the hook, whereafter the screw can be inserted therein. The screw then engages the edge of the aperture and the concave portion of the hook. The hook itself is inserted through an aperture in a rail and is held against one of its sides, so that the plate is drawn perpendicularly against the opposite side of the rail.
