Definitions

• the invention relates to a process for manufacturing, curing, protecting and carrying balusters of any kind characterised in using a disposable cover-mould prefabricated to this end in a plastic or any other kind of material which is filled with concrete and allowed to harden inside.
• balusters of this kind are manufactured using retrievable moulds comprising two or more parts, which are used repeatedly.
• the manufacturing process requires the said moulds to be filled with mortar or concrete, and allowed to harden and once this process is over the mould will be opened and the resultant baluster removed which shall next be checked to cover up flaws therein, such as marks made by the mould seam, hollows, pores and the like, for this system does not allow mechanical filling, and vibration processes only with great difficulty.
• baluster moulds are moreover filled one by one and their later treatment must therefore be independent.
• the system of the invention considerably improves the current state of the art, yielding a high quality and high performance baluster obtaining the following advantages:
• Each baluster will be internally fitted with a metallic reinforcement framework or rod, which may optionally project from either or both ends.
• the cover-mould can have different shapes and dimensions, which will allow the structure of the baluster manufactured to be varied.
• the cover-mould may be easily detached from the baluster manufactured, pulling from it after making just a simple cut.
• the manufacturing process subject of the invention essentially comprises placing on a pallet, wooden or suitable material base, a set of prefabricated cover-moulds, next to each other and held by means of a metallic structure perimetrically embracing the lot.
• This structure can be removed and once the covers have been filled with concrete and the setting process has begun, the structure is removed from the pallet or base with only the set of balusters manufactured remaining, which shall be carried to their destination upon the same pallet.
• the concrete is put into the cover-moulds via a vibratory hopper or platform that in turn has manifold outlets, as many as there are balusters to fill. These outlets will be connected to as many pipes carrying and injecting the concrete down to the bottom of the cover-mould, to begin the filling process upwards from the bottom, and the hopper or platform will at the same time transmit vibration to each baluster by means of the filling pipes or injectors.
