Building component

Abstract

A building component is in the form of an elongate prefabricated cornice to be used in lengths around the top of a wall or walls or a room. The cornice has a mounting part and a facing part. The mounting part has a cross-section with two legs at an angle to each other. The outer edge of each leg terminates in a reflexive bend with the outer portion of the bends inwardly directed. The facing part is a strap of material capable of being snap-fitted into or slid along the mounting part with the inside of each bend serving as a seat to receive a longitudinal edge of the facing part. A corner-piece is provided to join two adjacent lengths of cornice at a corner, the corner-piece being in two parts having a wall-mountable angle bracket and a correspondingly angled cornice part to be secured thereto.

I claim:  
     
         1 . A building component in the form of an elongate prefabricated cornice to be used in lengths around the top of a wall or walls, the cornice having a mounting part and a facing part, the mounting part having a cross-section with two legs at an angle to each other, the outer edge of each leg terminating in a reflexive bend with the outer portion of the bends inwardly directed, the facing part being a strap of material capable of being snap-fitted into or slid along the mounting part with the inside of each bend serving as a seat to receive a longitudinal edge of the facing part.  
     
     
         2 . A building component according to    claim 1   , wherein the facing part is of thin material and is provided with a design thereon, for example a series of corrugations whose axes are parallel to the axis of the facing part.  
     
     
         3 . A building component according to    claim 1   , wherein the outer part of the bend to be located adjacent to a ceiling is extended rearwardly from the bend to provide a lip whose outer edge, in use, is to abut the ceiling.  
     
     
         4 . A building component according to    claim 1   , wherein a corner-piece is provided to join two adjacent lengths of cornice at a corner, the corner-piece being in two parts having a wall-mountable angle bracket and a correspondingly angled cornice part to be secured thereto.  
     
     
         5 . A building component according to    claim 4   , wherein the bracket has a channel formation formed by two limbs extending out from its vertex, the outer ends of both channel limbs having first part gripping means extending inwardly of the channel and the cornice part having a tongue rearwardly-projecting from its vertex, the tongue having second part gripping means, the first and second part gripping means catching when pressed together.  
     
     
         6 . A building component according to    claim 5   , wherein the first part gripping means is inwardly-extending barbs and the second part gripping means is a series of parallel hook formations to be presented in a parallel attitude to the barbs.  
     
     
         7 . A building component aaccording to claims  4 , wherein the cornice part has two similar tapered walls, each having a similar design thereon shaped to complement the tapered walls which terminate at their lower end in a ledge having an internal groove accessed from the back of the cornice part.  
     
     
         8 . A building component according to    claim 7   , wherein a finial is provided having a slide to seat in the groove with the finial extending down from the ledge.
