Definitions

  • This invention relates to a thrust containment frame for a disposable form.
  • the invention applies to the building sector, and in particular to the construction of buildings with load-bearing partitions.
  • such frames are mainly made in-place, by anchoring long horizontal metal bars which have a containment action on two or more adjacent panels.
  • the bars mainly press against wooden thrust containment sheets (usually recognisable by their yellow colour) which abut against the panel of the form to distribute the stresses.
  • the bars are usually fitted after vertical positioning of all of the panels (and therefore of the forms) and anchored using suitable tapered pins.
  • anchoring between the thrust containment structural work and the frame is produced using non-removable metal plates or bars, which after the casting are broken to allow removal of the panel structural work.
  • thrust containment structure of the prior art are known form documents DE19643800 and US5375809 .
  • the aim of this invention is to provide a thrust containment frame for disposable forms that overcomes the above-mentioned drawbacks of the prior art.
  • this invention has for an aim to provide a thrust containment frame for disposable forms which is very strong and easy to fit.
  • this invention has for an aim to provide a thrust containment frame for disposable forms which is modular and fully reusable.
  • the numeral 100 denotes a thrust containment frame for a disposable or non-reusable (construction) form according to this invention.
  • Each form 20 (or formwork) comprises a pair of construction panels 10.
  • each panel 10 is provided with a reinforcement mesh 1 to be embedded in the concrete after casting so as to create the reinforced concrete structure.
  • the mesh 1 comprises a plurality of metal bars 2, 3 (preferably made of construction steel) mutually arranged to create a grid of first 2 and second bars 3 intersecting each other.
  • first bars 2 are at right angles to the second bars 3 and each second bar 3 is connected to all the first bars 2 at respective coupling nodes 4 (where the bars are jointed by a hook made of harmonic steel).
  • the mesh 1 comprises at a least a pair of first bars 2 and a plurality of second bars 3.
  • Both the first 2 and the second bars 3 are parallel with each other and spaced with a predetermined spacing.
  • the first bars 2 are parallel with, and at a predetermined distance from, each other.
  • the second bars 3 are parallel with, and at a predetermined distance from, each other.
  • the mesh is applied on the face of a panel 10 (which will be described in more detail below) preferably by arc-welding.
  • the first bars 2 are, again in use, orientated vertically, whilst the second bars 3 are oriented horizontally.
  • first bars 2 define (in combination with the corresponding first bars 2 of a panel 10 above or below) the vertical chains of the partition.
  • second bars 3 define (in combination with the corresponding second bars 3 of an adjacent panel 10) the horizontal chains of the partition.
  • each second bar 3 extends along a respective main direction between a first end 3a and a second end 3b, each provided with a through socket 5.

  • terminal portions 7 of a single second bar 3 are folded back on themselves (by special folding means) for forming the socket 5, clousing on the intermediate section of bar nearest to the socket with a superposed portion of a predetermined length (in the embodiment illustrated 10 centimetres).
  • a distance between the centres of the sockets 5 of each horizontal bar substantially corresponds to the width of the panel 10 on which the mesh 1 is mounted.
  • each through socket 5 is substantially coaxial with the through sockets 5 of the corresponding ends 3a, 3b of the other second bars 3 (of the same mesh 1) so as to define a joining line.
  • Said joining line may run along a third bar 6 for the connection, during assembly, of two meshes 1 adjacent to each other.
  • the sockets 5 of the second ends 3b of the second bars 3 of a single panel 1) are aligned with each other along the above-mentioned joining line, which is vertical in use.
  • the sockets 5 of the first ends 3a of the second bars 3 are aligned with each other along the above-mentioned joining line, which is vertical in use.

  • the panel 10 comprises a second face 10b, opposite the first face 10a, provided with a roughness such that is forms a sequence of small grooves and apexes (preferably micro-corrugations) for promoting improved adherence of the plaster.
  • a lightweight mesh (not illustrated) is embedded in the panel 10, designed to stabilise the panel, providing greater panel strength and reducing the likelihood of sliding between the two faces.
