The wall members 2 have their ends internally threaded and coacting therewith are removable conical collars 7 having screwed extensions to secure the shuttering to the wall member. Integral ribs or collars may be provided on the members 2 to prevent their withdrawal from the wall. The conical collars on one side of the wall are removed together with the shuttering and are replaced by bayonet sockets 4 each having a conical extension 8 ; each socket also has a screwed extension or is secured to the wall member by a bolt. The ends of the bracket members 10 are provided with projections 12 adapted to engage the bayonet sockets and hold the brackets in position. The Specification as open to inspection under Sect. 91 comprises also the use of superposed brackets interconnected at their outer ends by uprights, the brackets being connected parallel to the wall by longitudinals at their outer ends. The uprights are formed in lengths which are connected together either by plug fittings or by screwed sleeve fittings, and the brackets are of triangular formation. This subject-matter does not appear in the Specification as accepted. |
