Já são conhecidos tubos cilíndricos retilíneos feitos de fita de chapa metálica, calandrada na forma helicoidal cujas bordas adjacentes das espiras são ligadas através de solda helicoidal contínua. Numa possibilidade, esse tubo de chapa helicoidal é aplicado em estaqueamento deStraight cylindrical tubes made of sheet metal tape, calendered in helical form, whose adjacent edges of the turns are connected by continuous helical welding, are already known. In one possibility, this helical sheet tube is applied to

fundações. Esse tubo normalmente é denominado Tubo Helicoidal de Cha15 pa, nomenclatura essa adotada neste relatório.foundations. This tube is usually called Helical Tube of Cha15 pa, nomenclature adopted in this report.

Normalmente, esses tubos são fabricados em unidades fabris compostas, essencialmente: por desbobinador da bobina de fita de chapa; por unidade de tração, que avança longitudinalmente a fita; por calandra, que conforma a fita na forma helicoidal; por máquina de solda, que 20 solda as bordas adjacentes das espiras da chapa dobrada em hélice, formando progressivamente o tubo; por uma pista de roletes, para apoio e avançoTypically, these tubes are manufactured in manufacturing units composed essentially of: by unwinding the sheet ribbon coil; per traction unit, which advances the ribbon longitudinally; by calender, which forms the ribbon in helical form; by a welding machine, which welds the adjacent edges of the helix-folded sheet turns, gradually forming the tube; by a roller track, for support and advancement

I / 19 do tubo à medida que este é fabricado, entre outros. Essas unidades fabris normalmente são estacionárias e distantes da obra, na qual o tubo é usado. Isso exige uma operação de transporte do tubo entre o local de fabricação e a obra.I / 19 of the tube as it is manufactured, among others. These manufacturing units are usually stationary and away from the work, in which the pipe is used. This requires a pipe transport operation between the manufacturing site and the construction site.

Apesar das unidades de fabricação estacionárias usuais desse tubo não terem limitações técnicas para produzi-lo com grandesAlthough the usual stationary manufacturing units for this tube do not have technical limitations to produce it with great

comprimentos, dito tubo tem que ser fabricado com comprimento relativamente curto, normalmente cerca de doze metros, para atender às limitações de transporte entre a fábrica e a obra. Apesar dos tubos serem relativamente curtos, doze metros, esse transporte entre a fábrica e a obra, pode ser relativamente complexo, principalmente dependendo das condições do trajeto.lengths, this tube has to be manufactured with a relatively short length, usually about twelve meters, to meet the transportation limitations between the factory and the work. Although the tubes are relatively short, twelve meters, this transport between the factory and the work can be relatively complex, mainly depending on the conditions of the route.

Por ouro lado, para que o transporte tenha custo adequado, há a necessidade de transportar vários tubos de cada vez, o que pode também ser um complicador.On the other hand, for the transportation to have an adequate cost, there is the need to transport several tubes at a time, which can also be a complicating factor.

Não raro, a sua aplicação tem comprimento maior que a do tubo convencional, o que exige a soldagem de tantos tubos quantos forem necessários para compor o comprimento das peças. Isso resulta em operação(ões) adicional(is) de soldagem feita(s) “in-loco”, o que pode ser indesejável e de alto custo.Not infrequently, its application is longer than the conventional tube, which requires welding as many tubes as necessary to compose the length of the pieces. This results in additional welding operation (s) performed on-site, which can be undesirable and costly.

Em razão dos aspectos acima, são desejáveis novas alternativas para tubo helicoidal de chapa metálica e/ou para o processo de / 19 fabricação do mesmo e/ou para transportá-lo entre a fábrica e a obra.Due to the above aspects, new alternatives for helical sheet metal tube and / or for the manufacturing process of the same and / or for transporting it between the factory and the work are desirable.

Assim, o objetivo da presente patente de invenção, é prover um meio de fabricação de tubos helicoidal de chapa metálica que supere os inconvenientes acima e outros verificados com os usuais.Thus, the objective of the present invention patent, is to provide a means of manufacturing helical sheet metal tubes that overcomes the above and other problems encountered with the usual ones.

Outro objetivo é prover um meio de fabricação queAnother objective is to provide a means of manufacture that

além de superar os problemas acima, não seja por isso de construção ou fabricação ou operação com níveis de complexidade que o tome desinteressante em face do usual.in addition to overcoming the above problems, it is not for that reason of construction or manufacture or operation with levels of complexity that make it uninteresting in the face of the usual.

Outro objetivo é prover um meio de fabricação de tubo helicoidal de chapa de modo que se obtenha melhores resultados de produtividade e custos adequados.Another objective is to provide a means of manufacturing a helical plate tube in order to obtain better productivity results and adequate costs.

pa obtido a partir de referidos meios de fabricação da presente patente, que apresente vantagens em relação aos tubos similares obtidos pelos meios de fabricação usuais.pa obtained from said means of manufacture of the present patent, which presents advantages in relation to similar tubes obtained by the usual means of manufacture.

Tendo em vista, portanto, os problemas acima referidos e no propósito de superá-los e visando atender aos objetivos relacionados, foi desenvolvida a fábrica móvel de tubos helicoidal de chapa , objeto da presente patente de invenção, a qual é compreendida, essencialmente: por 20 desbobinador; por unidade de tração; por prensa para emenda; por calandra;Therefore, in view of the aforementioned problems and in order to overcome them and aiming to meet the related objectives, a mobile helical tube factory was developed, object of the present invention patent, which is essentially understood: by 20 unwinder; per traction unit; by splicing press; by calender;

por máquinas de solda; por pista de roletes; por grupo gerador e por todosby welding machines; by roller track; by generator set and by all

I’ / 19 demais equipamentos necessários à fabricação de tubo helicoidal de chapa , montados em uma carreta baixa dotada de fechamentos laterais, posterior e superior, dentre os quais os laterais são articulados e se movem entre posição vertical, quando atuam como fechamentos propriamente ditos e posição horizontal, quando atuam como passarela junto ao equipamento de fabricação; dita carreta é puxada por cavalo mecânico dotado de guindaste, para movimentação de materiais e outros. Referida fábrica é formada ainda por caminhão auxiliar para o transporte de partes desmontáveis da fábrica, ferramentas, equipamentos e demais necessários à fabricação do tubo.I '/ 19 other equipment necessary for the manufacture of helical plate tube, mounted on a low cart with lateral, rear and upper closures, among which the lateral ones are articulated and move between vertical positions, when they act as closures themselves and horizontal position, when they act as a footbridge next to the manufacturing equipment; said cart is pulled by a mechanical horse equipped with a crane for handling materials and others. Said factory is also made up of an auxiliary truck for the transport of detachable parts of the factory, tools, equipment and other necessary for the manufacture of the tube.

Essa disposição da fábrica de tubos helicoidal de chapa , portanto, é móvel e totalmente auto-suficiente superando assim os problemas acima referidos, já que a mesma pode se deslocar até a obra e nesta fabricar os tubos nos diâmetros e nos comprimentos que for necessário “in-loco”, evitando o transporte destes entre o local de fabricação e a obra e todos os problemas decorrentes disso. Tal solução apóia-se também no fato de que é mais simples e de menor custo transportar bobinas de chapa de aço até a obra do que transportar os tubos já fabricados.This arrangement of the helicoidal tube factory, therefore, is mobile and totally self-sufficient, thus overcoming the problems mentioned above, since it can travel to the construction site and manufacture the tubes in the diameters and lengths that are necessary “ in-loco ”, avoiding the transport of these between the manufacturing site and the work and all the problems resulting from it. Such a solution is also supported by the fact that it is simpler and less costly to transport steel sheet coils to the construction site than to transport the tubes already manufactured.

Outra vantagem expressiva obtida com a presente fábrica diz respeito ao fato de que, uma vez que o tubo é fabricado “in-loco” e não havendo assim necessidade de transportá-lo entre o local de fabricação e a obra, referido tubo pode ser produzido com o comprimento desejado pa- / 19 ra as diversas aplicações, dispensando a(s) operação(ões) de solda(s) entre tubos até compor o comprimento desejado, conforme ocorre usualmente, facilitando os trabalhos no canteiro de obras.Another significant advantage obtained with the present factory concerns the fact that, since the tube is manufactured “on-site” and therefore there is no need to transport it between the manufacturing site and the work, said tube can be produced with the desired length for the various applications, eliminating the weld operation (s) between tubes until it composes the desired length, as usually occurs, facilitating work on the construction site.

Por outro lado, o fato do tubo poder ser produzido diretamente no comprimento desejado simplifica a sua fabricação e melhora sua constituição, já que não terá soldas de ligação, conforme ocorre usual-On the other hand, the fact that the tube can be produced directly at the desired length simplifies its manufacture and improves its constitution, since it will not have connection welds, as usually occurs-
