A floating cover roof for a storage tank has a frame assembly and multiple floating units. The frame assembly has a holding frame and an outer rim. The holding frame has multiple longitudinal beams and transverse beams. Each longitudinal beam has a connecting seat, a first holding segment and a second holding segment. Two of the transverse beams are connected to two adjacent longitudinal beams to form a locating area between the beams. The floating units are mounted in the locating areas of the frame assembly, are connected to the beams of the holding frame and each has an outer casing and a body. The outer casing is mounted in one of the locating areas of the holding frame, is connected to the adjacent beams and has a casing body and a top board. The body is mounted in the outer casing between the casing body and the top board.

The invention relates to a shaft and hub connection (20) for transmitting torque, a common longitudinal axis (X-X) comprising the following components: a shaft (22) which rotates about the longitudinal axis (X-X) and comprises an entraining longitudinal section having an untrue outer contour (26), and a hub (24) that is coaxial to the shaft (22) and encloses the shaft (22) with its internal contour (28) at least in the area of the entraining longitudinal section. The invention is characterized in that the outer contour (26) of the entraining longitudinal section of the shaft (22) and the inner contour (28) of the hub (24) have the shape of a perfect cone to such a degree that, when the shaft (22) and the hub (24) are assembled, they automatically self-lock, thereby holding the shaft and hub connection (20) together. The connection also comprises connecting means which prestress the shaft (22) and the hub (24), when assembled, in the direction of the longitudinal axis (X-X).

A handlebar grip for a transportation vehicle includes a grip body having a body portion and an annular flange provided on one end of the body portion, a tightening member mounted on the outer surface of the annular flange, a locating ring mounted on the outer surface of the annular flange in such a way that the tightening member is placed in between the locating ring and the annular flange, and a fastener inserted into a through hole of the locating ring. When the fastener is fastened up, one end of the fastener leans against the outer surface of the tightening member such that the annular flange of the grip body is pressed by the tightening member to be radially inwardly deformed and compressed against the periphery of a handlebar of the transportation vehicle. Thus, the handlebar grip is firmly fixed to the handlebar of the transportation vehicle.
摘要:
An elongated clamp for securing a flexible fabric like shroud to a scaffold support member including to opposed jaws movable between an open and closed position by a pin and wedge combination. The flexible shroud is held to the support member by the clamp gripping force. Multiple clamps securable at different points along the various standard support members provide positive securement of the shroud.

A seismic adapter for attachment to a steel web joist. The joist includes a pair of angled elements which extend parallel to one another with a cord space therebetween. The adapter includes an anchor plate juxtaposed with the upper surface of the element pair and an engagement plate engaging the parallel edges of the legs of the element pair. A threaded stud attaches to the anchor plate and extends through the engagement plate. The extension of the stud provides for the attachment to a hanger adapter brought together by a nut on the stud. The engagement plate includes a flat anchor portion and upstanding engagement portions having distal edges with interlocking engagement profiles including a tongue and outwardly extending shoulders to receive the parallel edges of the angle element pair.
