Abstract: A ceiling framework includes main beams and cross beams, which are connected to one another and transversally to one another by connectors borne by one type of beams among the main beams and the cross beams, and engaged in apertures made in the other type of beams among the main beams and the cross beams, so as to receive tiles. For each beam having the apertures, the apertures are marked with symbols on each face of the beam, the symbols marked on each face being repeated sequentially over the length of the beam, the period of the sequences of symbols on each face being equal to a given tile size. The marking is the same on either face of the beam, starting with the same symbol on each left-hand or right-hand end for each observed face.

Abstract: A connector for a ceiling framework including profile sections crossing one another at right angles for connecting the profile sections by being fitted to ends of certain profile sections which fit into apertures pierced in other profile sections. The connector includes two parts, a primary clip and a secondary clip, the two parts being associated with one another via a meltable mechanism capable of melting at a temperature of a fire to separate the two parts. In a fire, the secondary clips become detached allowing the primary clips to fit more deeply into the apertures of the profile sections, making it possible to absorb expansions due to heat of the fire and keep the framework and the ceiling sections it supports in place. The connector can be applied to the field of building construction, for example.
