Definitions
- the invention relates to a, in particular suspended as a suspension framework or suspended scaffold, comprising a, preferably elongated, in particular as an extruded light metal U-profile carrier or aluminum extruded U-profile carrier formed, U-profile Carrier, which extends along its U-profile support longitudinal axis and has an outwardly open U-profile, and comprising at least one releasably fixed to the U-profile scaffold floor, one or more suspension hooks, at one end -
- U-profile carrier support legs which are arranged parallel to each other and parallel to the longitudinal center plane of the U-profile, the Durc h a transverse wall are connected to each other and have, preferably at their free ends, support edges for placing
- the invention also relates to a method for securing at least one scaffold floor of a scaffold which can be suspended or suspended, in particular as a suspension scaffold, against lifting one or more suspension hooks arranged on one end side of the at least one scaffold floor, for example in the form of an or a plurality of claws or claws, of a U-profile of a U-profile carrier, preferably elongate, in particular designed as extruded light metal U-profile carrier or aluminum extruded U-profile carrier, wherein the U-profile, which is open towards the outside, of the U-profile carrier extending along its U-profile carrier longitudinal axis has supporting shanks which are arranged parallel to one another and parallel to the longitudinal center plane of the U-profile, which are interconnected by a transverse wall are and which, preferably at their free ends, support edges for placing the suspension hook or hooks of at least one Gerüstbo and wherein the U-profile carrier has a guide and fastening groove, which is delimited by the transverse wall and opens in the
- a hook-in hook of a scaffold floor is secured against lifting out of a U-profile of a U-profile beam formed with two parallel support legs by means of a lifting hook which engages over the suspension hook in the form of a perforated disc.
- the U-profile carrier has on its side facing away from the U-profile side with this integrally connected connection part.
- the connecting part has two attachment legs extending laterally beyond the two support legs of the U-profile, via which the U-profile support is detachably fastened to an elongated scaffolding tube by means of a connection pipe coupling designed with a coupling half shell.

- the suspension hook and consequently the framework floor can not be displaced relative to the longitudinal axis of the U-profile of the U-profile carrier.
- the safety wedge would first have to be loosened by releasing the clamp by means of a tool, such as a hammer. But then there would be the risk of unintentional lifting of the suspension hook of the scaffold floor from the U-profile and consequently a dropping of the scaffolding floor in connection with a danger to life and limb.
