Definitions

  • the present invention relates to an adjustable length stay for the building industry.
  • these stays are usually used for supporting the temporary forms provided for receiving the reinforced concrete castings and are conventionally formed by two iron pipes which are telescopically coupled to one another and which, at their free end portions are provided with welded supporting bases.
  • These telescopic pipes can be adjusted in height, and this heigth adjustment is usually obtained by providing the pipes with a plurality of holes and an engaging pin and, in order to achieve a fine adjustment, there is provided a threaded sleeve element which is threaded on the threaded end portion of the bottom pipe so as to affect the pin engaged in a given hole, to provide the fine adjustment, at the stay height, in order to hold in a accurate horizontal position the casting mold.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by greatly reducing the making cost of the threaded pipe portion, while eliminating the cost of welding the threaded portion on the outer pipe of the stay.
  • a main object of the present invention is to provide a new type of stay for the building industry, which can be made by a very reduced number of making steps.
  • Another object of the present invention is to provide an automatized method of very high yield for making the above mentioned stays.
  • Yet another object of the present invention is to provide such a stay which can be easily and quickly constructed starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • an adjustable length stay for use in the building industry, comprising an outer tubular element and an inner tubular element, said tubular elements being respectively coupled to supporting bases and being telescopically associated with one another, a threaded sleeve being moreover provided which can be screw engaged with an outer threaded portion of said outer tubular element and which can be abutted against a pin element which can be in turn engaged in holes provided through said inner tubular element, characterized in that said outer threaded portion is made as a single piece with said outer tubular elements.
  • the adjustable length stay for use in the building field according to the invention which has been generally indicated at the reference number 1, comprises an outer tubular element 2 and an inner tubular element 3 which, at the free end portions thereof, are connected, usually by means of welding, to supporting bases, respectively indicated at 4 and 5.
  • tubular elements 2 and 3 can be telescopically coupled to one another, so as to provide the possibility of easily adjusting, depending on the contingent requirements, the height of the stay.
  • the tubular element 2 is provided, at its coupling end, with an outer threaded portion, indicated at the reference number 10, which engages with an inner thread 11 of a sleeve element 12 which is provided, on its outer surface, with engaging lugs 13 and which abuts, at one axial end portion thereof, against a pin 20, which, in turn, can be engaged in holes 21 which are formed through the inner tubular element, so as to provide a first coarse adjustment of the length of the stay.
  • the fine adjustment of said length can be performed by means of the sleeve element which, as stated, is provided with a threaded coupling portion.
  • the main feature of the invention is that the threaded portion 10 is made in a single piece with the outer tubular element, that is said threaded portion 10 does not pertain to a piece which is separately made and must be successively welded to the stay.
  • the threaded portion 10 is made by a rolling machine, which will roll the outer surface of the outer tubular element so as to provide the thread therein.
  • This method is very important, since it allows to automatize the making line and, moreover, by eliminating the separate element to be welded, provides the stay with a greater mechanical strength.
  • this method allows to automatize all of the making steps, thereby greatly reducing the making cost of the stay.
