Definitions

  • This invention relates to a method for replacing a glass panel in a curtain wall and to an anchoring device used for replacement.
  • the method and device according to the invention apply to structural silicone curtain walls (or facades), that is to say, curtain walls characterized by a metallic supporting frame (defined by a framework of vertical and horizontal members) and curtain panels glued to the frame by means of silicone adhesives in such a way as to hide the frame almost completely.
  • structural silicone curtain walls or facades
  • curtain walls characterized by a metallic supporting frame (defined by a framework of vertical and horizontal members) and curtain panels glued to the frame by means of silicone adhesives in such a way as to hide the frame almost completely.
  • the invention is therefore applicable in particular to the sector of building construction and, more specifically, in the non-routine maintenance of buildings, for the replacement of damaged or worn panels of curtain walls.
  • replacement of a pre-existing damaged panel with a new component is a problematic operation, commonly considered critical, because up to now it has been impossible to restore the original structure.
  • replacement of the glazing involves the use of special mechanical fixing tools which interact with the panel in order to hold it in place while the sealing material dries but which cannot then be completely removed.
  • U-shaped fixing point ducts (not present in the original panel) are fitted to the perimeter of the glazing panels and used to fix and seal the glazing to the frame.
  • a plurality of angular members are riveted to the structure of the building and then bolted to the panel in the duct cavities so as to keep the panel in position.
  • This method entails making a panel with different sized layers of glass in order to create a indented perimeter (on the inside) where a mounting unit can be fitted for the panel to be bolted.
  • the mounting unit is in turn provided with holes for receiving "outside” bolts which, once the panel has been positioned, are tightened from the outside of the building structure.
  • the aim of this invention is to provide a method and a device capable of overcoming the above mentioned disadvantages of the prior art.

  • the replacement panel is then positioned at the opening to block it in such a way that the first face of the panel partly abuts against an outer side of a vertical member and/or of a beam of a load-bearing structure of the curtain wall.
  • the replacement panel is made to abut against the pre-existing vertical member or beam without any auxiliary element being interposed between them (except for sealant or seals).
  • the panel is then fixed to the vertical member and/or beam by means of an anchoring device and, after that (but in some cases also before that), a layer of sealing material is spread at a joining zone between the first face of the panel and the side of the vertical member and/or of the beam.
  • the anchoring device After waiting for a predetermined period of time ⁇ T for the layer of sealing material to dry, the anchoring device is removed, thereby restoring the original structure of the panel, that is, of the curtain wall.
  • the step of fixing the replacement panel to the vertical member and/or to the beam comprises a step of pulling the first face of the panel or pushing the second face of the panel using the anchoring device in order to keep the first face in abutment against the second side of the vertical member and/or of the beam during the predetermined period of time ⁇ T.
  • the method comprises preparing a contact element having a fixed position relative to the required position of the panel.

  • a frame is positioned in contact with the first side of the vertical member and/or of the beam to form a contact element facing the first face of the panel.
  • the retaining unit (preferably slidably associated with the frame) is then moved towards the frame and locked in place relative to the frame when the panel exerts a predetermined pressure on the second side of the vertical member and/or of the beam.
  • the retaining unit and the frame are connected by a threaded coupling or a pawl mechanism.
  • the method entails fixing a frame to at least one element of the building or of the curtain wall, on the outside and adjacent to the panel to be replaced in such a way as to define the contact element facing the second face of the panel.

  • the pulling action is stopped, preferably by removing whatever means were used to apply it, in particular the anchoring device 1.
  • the step of fixing the replacement panel 100 to the vertical member 102 and/or to the beam comprises (alternatively) a step of pulling the first face 100a of the panel 100 or a step of pushing the second face 100b of the panel 100 using the anchoring device 1 in order to keep the first face 100a in abutment against the second side 102b of the vertical member 102 and/or of the beam during the predetermined period of time ⁇ T.
  • the method according to the invention preferably has two alternative (or complementary) embodiments.
  • the step of fixing the replacement panel 100 to the vertical member 102 and/or to the beam comprises a sub-step (preferably performed in the factory) of fixing a retaining unit 2 to the first face 100a of the replacement panel 100 followed by a sub-step (performed on site) of pulling the retaining unit 2 in such a way as to press the first face 100a of the panel 100 onto the second side 102b of the vertical member 102 and/or of the beam of the load-bearing structure 101, using a suitable pulling unit 5.
  • the retaining unit 2 is fixed by spreading a layer 3a of adhesive material between the retaining unit 2 and the first face 100a of the panel 100 and then abutting the retaining unit 2 itself against the panel 100.
  • the method after abutting the retaining unit 2 to the panel 100 (preferably positioned horizontally to take advantage of the force of gravity), there is a step of waiting for a period of time ⁇ T2 for the adhesive material to dry.
  • the replacement panel 100 is then positioned in the opening "O", that is, abutted against the second side 102b of the vertical member 102, in combination with the retaining unit 102 previously fixed to the inner face (or first face) 100a of the panel 100.
  • the retaining unit 2 is removed, as is any residual adhesive material still sticking to the first face 100a of the panel 100.
  • the residual adhesive material may be scraped off or dissolved chemically.
  • the step of fixing the retaining unit 2 to the first face 100a of the replacement panel 100 is accomplished by suction, preferably by means of a suction cup or electric suction cup.
  • the step of removing the retaining unit 2 does not leave any residue on the panel 100, which is immediately restored to its original operating conditions.
  • the method comprises positioning a frame 6 in contact with the first side 102a of the vertical member 102 and/or of the beam to form a contact element facing the first face 100a of the panel 100 and moving the retaining unit 2 towards the frame 6.
  • the retaining unit 2 is then locked in the position corresponding to the predetermined condition where the panel 100 in turn applies a predetermined pressure on the outer side 102b of the vertical member 102 and/or of the beam.
  • this step of positioning the frame 6 comprises placing a crosspiece in contact with two successive vertical members 102 or beams of the load-bearing structure 101.
  • the step of moving the retaining unit 2 towards the frame 6 is preferably accomplished by tightening a threaded coupling 8, and more specifically, the threaded coupling described previously.
  • the movement might be accomplished by actually pulling the retaining unit and then locking it in place by means, for example, of a pawl mechanism.
  • the step of fixing the replacement panel 100 to the vertical member 102 and/or to the beam comprises a sub-step of preparing a pushing unit 22 to be abutted against the second face 100b of the replacement panel 100 and a sub-step of pushing the pushing unit 22 against the second face 100b in such a way as to press the first face 100a of the panel 100 onto the second side 102b of the vertical member 102 and/or of the beam of the load-bearing structure 101, using suitable pushing means.
  • the step of pushing the pushing unit 22 is accomplished by fixing a frame 26 to at least one element of the building or of the curtain wall 110 on the outside and adjacent to the panel to be replaced (preferably a panel adjacent thereto) in such a way as to form a contact element facing the second face 100b of the panel 100.
  • the step of fixing the frame 26 to the elements of the building or of the curtain wall 110 on the outside and adjacent to the panel to be replaced is accomplished by applying a layer of adhesive material 23a between these elements and a joining portion of the frame 26a.
  • the pushing unit 22 is then moved away from the frame 26 against the second face 100b of the panel 100.
  • the pushing unit 2 is then locked in the position corresponding to the predetermined condition where the panel 100 in turn applies a predetermined pressure on the outer side 102b of the vertical member 102 and/or of the beam.
  • the invention achieves the proposed aims and brings significant advantages.
  • the device necessary to implement the method is very simple to make and does not require any alterations to or preparatory operations on the load-bearing structure or replacement panel.
  • the retaining unit can, advantageously, be positioned in the factory or, in any case, on the ground, by applying the adhesive material and only the "mechanical” pulling step is performed on site (that is, with the panel vertical) when the retaining unit is securely connected to the panel.
