Definitions

  • the present invention relates to a support and centering device for a fixing bar, comprising an annular support element and a plurality of stabilizing elements, and the related positioning method.
  • the wall usually made of plain or reinforced concrete, is drilled with a drilling device such as a drill, creating an internal cavity.
  • the hole is made with an inner diameter of a larger size than the outer diameter of the fixing bar to be inserted, so that, in addition to the bar, it may also contain a stabilizing adhesive material, such as epoxy chemical anchor.
  • the hole is made in the wall, said hole is cleaned, such as by means of compressed air and brush, and is typically washed.
  • the stabilizing adhesive material is then inserted into the hole, and the fixing bar is inserted into the hole.
  • the curing time in which the adhesive material sets and develops a mechanical strength so that the bar is solidly clamped to the hole in a predetermined position with a high sealing efficacy.
  • This curing time may vary depending on many parameters, such as the temperature and/or humidity of the surrounding environment. On average, with the previously mentioned materials, this curing time may vary between 5 and 6 hours with processing times ranging from 20 to 30 minutes.
  • This method for inserting a fixing bar into a concrete wall is suitable when a limited number of bars are to be fixed in the wall, or in those circumstances in which waiting the predetermined time for the resin to cure will not alter, delay, or preclude the progress of the construction work.

  • devices used for supporting the bar and the respective centering in the hole during the curing of the adhesive material are also known in the art. Such devices are essential to enable the development and maintenance of proper tension at the interface between the bar and resin and between the resin and the inner hole cavity during the curing time, and thus to ensure proper sealing of the bar in the concrete wall when positioning and fixing are complete.
