Definitions

  • the field of the invention is that of the design and manufacture of equipment for the renovation of buildings.
  • the invention relates to means for fixing a scaffolding on a building having thermal insulation from the outside (ITE).
  • a widely used solution for this is to lay a thermal insulation layer on the outside of the building.
  • this solution makes it possible to keep an internal volume of the building equal to the internal volume before renovation.
  • the insulating layer does not reduce the internal volume of the rooms and the occupants of the building can maintain an identical useful surface while benefiting from reduced energy consumption since the heating requirements and / or air conditioning are less important.
  • scaffolding is mounted all around the buildings.
  • the scaffolding is secured to the buildings. This joining is carried out using anchoring means each comprising an anchor fixed in the wall of the building and a fastening part integral with the scaffolding, which engages with the anchor.
  • the workers cut out a part of the ITE (usually a sheet of foam or polystyrene) to bypass the scaffolding anchoring means and then position the ITE against the wall .
  • the ITE is then covered with a hanging cloth which is itself covered with a layer of plaster.
  • the coating layer is painted in the colors chosen for the building.
  • the scaffolding is dismantled.
  • the anchoring means When dismantling the scaffolding, the anchoring means are removed, leaving a hole in the ITE layer.
  • This hole is then filled by injection of an expansive foam, then a finishing connection is carried out by laying a hanging cloth then a layer of plaster and finally a layer of paint.
  • the finishing connection being made in a secondary time to the plaster and the painting of the rest of the building, the conditions of application of the paint in particular are not identical. Indeed, the paint can be of different composition and the weather conditions also.
  • the paint done during the finishing fitting step usually takes on a slightly different tone than the rest of the building.
  • the hanging cloth used for the finishing connection has dimensions much greater than the hole to be covered.
  • the hanging fabric which is larger than the hole to be filled in, is rarely centered on said hole. Indeed, the centering of the hanging canvas would require a longer time which the workers do not have.
  • the object of the invention is in particular to overcome the drawbacks of the prior art.
  • the invention aims to provide a solution for the installation of a thermal insulation layer from the outside on a building provided with a scaffolding, which allows several scaffolding fixing spaced in time without harming thermal insulation from the outside.
  • the object of the invention is also to provide such a solution which leaves no traces, or almost, of the attachment of the scaffolding to the building after dismantling of the scaffolding.
  • the invention further aims to provide such a solution which is simple and quick to implement.
  • This process makes it possible to maintain the integrity of the thermal insulation layer after dismantling the scaffolding, while allowing, for the future, to be able to fix a new scaffolding without having to further degrade the thermal insulation layer.
  • an erection plan can be determined for all future work on the exterior of the building, and the workers in charge of erecting the scaffolding can do it without recourse. tools such as a drill and the need to re-drill the wall and / or thermal insulation layer.
  • each sealing plug is also painted, then the conditions of application of the paint are identical for the sealing plug and the building, this which makes it possible to obtain similar shades both for the sealing plug and for the building.
  • the insulation foam is inserted into each tube prior to the step of fitting the sealing plugs.
  • Such a device is simple to produce and makes it possible to insulate the anchor from the thermal insulating layer while guaranteeing future access to the anchoring orifice.
  • the collar makes it possible in particular, when it comes to bear on the thermal insulating layer, to produce a stop for driving the tube in with respect to the thermal insulating layer.
  • sealing plug allows the tube to be closed when the anchor is removed for dismantling the scaffold.
  • the tube is a tube split over its entire length.
  • the slot of the tube thus makes it possible, by plastic deformation of the tube, to be able to adapt its diameter as desired, that is to say according to the needs and the size of the anchors in particular.
  • the slot also makes it possible, if necessary, to bring the tube radially on an anchor, rather than longitudinally.
  • the holding means then make it possible, when the diameter of the tube is selected and applied to the tube, to retain its diameter for its use.
  • the holding means make it possible to maintain the diameter of the tube when the latter is placed around the anchor.
  • the tube would then tend to recover its initial diameter, often less than the diameter of the anchor.
  • the device also comprises a hooking fabric projecting radially from the tube, the hooking fabric being integral with the collar.
  • the hanging cloth makes it possible, by being applied to an outer face of the thermal insulating layer, to be able to be embedded in the coating applied to the thermal insulating layer in order to hold the marking device in position.
  • this hanging canvas allows the plaster to hang on the wall and to prevent the plaster from being detached from the wall after drying.
  • the device comprises connection means between the sealing plug and the tube.
  • the sealing plug when the sealing plug is painted, it can dry by remaining attached to the tube without having to position it in a particular place, or even risk losing it.
  • the connecting means may in particular be breakable when the sealing plug is in place, or else movable relative to the tube to keep it in place when the sealing plug closes the tube.
  • the device comprises means for retaining the sealing plug on the first end of the tube.
  • Such retaining means are simple to produce and operate easily. Indeed, these retaining means allow clipping of the sealing plug on the tube, which ensures both retention and allows, audibly or even haptically, the worker to ensure the correct positioning. the blanking plug.
  • the collar comprises a hook forming a housing for receiving the sealing plug.
  • the aesthetic appearance of the sealing plug makes it possible both to make the building attractive, but also to make it possible to identify the location of the anchoring hole for fixing a new anchor.
  • the figure 1 illustrates a device 1 for locating anchor holes 2 (visible on the figures 7 and 8 ), according to the invention, for the implementation of a process for renovating a building to insulate it thermally from the outside.
  • the anchoring hole 2 is made in a wall 3 of a building and is intended to receive an anchor 4 of anchoring means for fixing to the wall 3 of a scaffolding 5.
  • the tube 11 is a split tube.
  • the tube 11 has a slot 111 over its entire length. It is thus understood that and the tube 11 and its collar 12 are both split.
  • the slot 111 makes it possible to obtain separate ends of the tube 11 in order to be able to adapt its diameter to requirements.
  • the device comprises holding means 17.
  • These holding means 17 are for example in the form of adhesive strips having a first portion secured to the tube 11 on a first side of the slot 111, and a second portion intended to be secured to the other part of the tube 11, on the other side of the slot 111.
  • retaining means 17 could be used such as, for example, mechanical means, means of the collar type or even flanges.
  • the tube 11 of the tracking device 1 has no slot 111 and has a fixed diameter.
  • the choice of the tracking device 1 to be used is made according to the length and / or the diameter of the anchor 4.
  • the hanging canvas 15 of the device 1 is a canvas forming a grid making it possible, as described below, to hang the layer 8 of plaster on the wall 3.
  • This hanging fabric 15 of the device 1 projects radially from the tube 11 and is in particular secured to the collar 12.
  • the tube 11 and the hanging fabric 15 of the device together form, when viewed from the side, a T.
  • the hanging fabric 11 of the device also has a slot 151 substantially collinear with the slot 111 of the tube 11. This makes it possible, as described below, to insert the tube 11 around an anchor 4 for fixing to the wall 3 of scaffolding 5.
  • the closure plug 14 has a plate 141 from which protrudes a cylinder 142, the cylinder 142 being intended to cooperate with the tube 11 to allow the first end 13 of the tube 11 to be closed by the closure plug 14.
  • the plate 141 of the sealing plug 14 is a plane support on the collar 12 of the tube 11 and the cylinder 142 of the sealing plug 14 is engaged inside the tube 11.
  • the device 1 comprises means 18 for retaining the sealing cap 14 on the first end 13 of the tube 11.
  • annular projection 182 is carried by the cylinder 142 of the closure plug 14.
  • the sealing plug 14 is connected to the tube by the connecting means 16.
  • These connecting means 16 are in the form of a strap having a first end integral with the closure plug 14 and a second end integral with the tube 11.
  • the sealing plug 14 remains integral with the tube 11 for in particular to avoid its loss.
  • the link is a breakable link which can be cut when the tube 11 is closed by the sealing plug 14.
  • the connecting means 16 are movable relative to the tube 11 and slide in the latter when the sealing plug 14 closes the tube 11.
  • the tube 11 of the tracking device 1 has a predetermined length calibrated with respect to a thickness of the layer 6 of thermal insulation to be applied to the wall 3.
  • the tube 11 could have a plurality of rings of small thickness, allowing cutting to predetermined lengths of the tube 11 as a function of predetermined thicknesses of layers 6 of thermal insulation.
  • the collar 12 of the tube of the tracking device has a hook 121 forming a housing for receiving the closure plug 14.
  • the tracking device 1 is made of a plastic material allowing it to be obtained by molding, for example.
  • the use of a plastic material makes it possible to avoid thermal conduction between the exterior of the building and the wall 3 of the building, that is to say through the layer 6 of thermal insulation.
  • a plastic material makes it possible to withstand weather conditions in a more durable manner compared to a metallic material such as steel for example.
  • the anchors 4 are rarely exactly perpendicular to the wall 3. It is therefore necessary to be able to deform the tubes 11 to allow them to properly surround the anchors 4 without there being any interference between. the tubes 11 and the anchors 4.
  • the device 1 for locating anchor holes which has just been described is used in particular for the implementation of a method of thermal insulation from the outside of a building.
  • the injected insulating foam 9 is covered with a layer of plaster which is itself painted.
