Abstract

A grid system for a suspended ceiling comprising mutually spaced main runners of T-profile suspended by means of hangers at the web of the T-profile, the flanges of the T-profile forming support surfaces for tiles. Apertures are punched at regular spacing in the web of the T-profile registering transversely of the main runners. Channeled girders opening upwards and extending over several main runners along registering apertures therein engage the main runners to define the spacing therebetween, the web of the T-profile being received in slots in the bottom and side walls (18) of the channeled girder. Each girder is fixedly connected with the runners by fastening elements engaging the apertures therein.
