Definitions

  • the present invention relates to a method for laying an insulating and/or waterproofing covering, in particular for lining civil construction works, such as roofs, floors, walls, paving, bridges, viaducts and roadbeds.
  • the method in question is designed to be advantageously used for the construction of thermal and/or acoustic and/or waterproofing insulating coverings using bitumen-based membranes and rigid or semi-rigid panels or flexible felts which can be made for example of cork, expanded polystyrene, extruded polystyrene, expanded polyurethane, wood, glass, or mineral fibres or wools, polyethylene or bituminous conglomerates.
  • insulating elements which are of varying shape and size and made of various materials are traditionally arranged on concrete, wood or fretted sheet-metal supports.
  • these elements in particular in the more common case of coverings for roofs, but also in the case of floor structures, are kept separate from the support to be covered by means of a waterproof layer arranged beforehand on the support - or base layer - in order protect the insulating elements from vapour and moisture coming from inside the building.
  • This waterproof layer which is known in the technical jargon of the sector as “vapour barrier”, is generally composed of a bituminous mass or more frequently by a bituminous waterproofing membrane which is made to adhere onto the base layer support by flame-heating in a traditional manner the bottom contact side, fixing the membrane mechanically either by means of hot-oxidized bitumen or using cold adhesives.
  • the insulating panel is fixed on top of the vapour barrier using cold adhesives, by means of mechanical fixing or by means of spreading of hot bitumen or also by heating the upper side of the bituminous waterproofing membrane which acts as a vapour barrier.
  • laying of the thermally insulating elements generally in the form of panels, always envisages two separate operations, namely a first operation for laying the waterproof layer, causing it to adhere onto the supporting surface of the concrete, wood or fretted sheet-metal base layer and then subsequently a second operation for laying the thermo-insulating layer, causing it to adhere onto the upper side of the waterproof layer, as explained above.
  • the thermally insulating layer may be further lined with one or more waterproofing membrane layers also of the mainly bituminous type.
  • the functions of the insulating layer and the waterproofing membranes are quite different.
  • the function of the insulating layer relates to thermal-acoustic insulation, in particular for retaining the heat inside the buildings.
  • the waterproofing membranes can be generally found on the market in the form of strips of flexible material which are wound in rolls and nearly always consist of a core, or reinforcement, lined with a mass of bituminous waterproofing material.
  • the reinforcement is intended to impart mechanical strength to the membrane and for this purpose is made of a synthetic fibre non-woven material or glass felt, or also film or plastic or metal sheets.
  • bituminous mass consists of "distilled” or “oxidized” bitumen mixed with thermoplastic polymers, such as polyolefins or styrene-butadiene in order to obtain waterproofing membranes respectively of the plastomer type (referred to by the abbreviation "APR") or of the elastomer type (referred to by the abbreviation
  • the membranes have a different mechanical behaviour and a different resistance to the variation in temperature.
  • the reinforcement may be lined on its two sides with waterproofing bituminous masses having different chemical/physical characteristics, resulting in a multiple-layer membrane with an optimum performance.
  • the waterproofing membranes need to be flame-heated by means of a gas torch in order to be able to adhere to the surface to be covered which may also be that of another waterproofing membrane in the frequent case where the provision of dual-layer or multiple-layer waterproofing is envisaged.
  • This method it is therefore possible to speed up only laying of the waterproofing covering in the particular case of dual-layer waterproofing systems if necessary on top of a thermally insulating covering.
  • This method also does not provide any information on the method of laying, in the building sector, coverings which are waterproofing and/or thermally insulating, this always being, as mentioned, negatively affected by the excessively long time required for laying of the insulating layer.
  • the main object of the present invention is therefore that of overcoming the limitations of the art known hitherto, as cited above, by providing a method for laying a waterproofing and/or insulating covering which can be simply and rapidly implemented.
  • Another object of the present invention is that of providing a method for laying a waterproofing and/or insulating covering which is low-cost and operationally entirely reliable.
  • the method for laying an insulating and/or waterproofing covering in question which comprises the following steps: arranging a waterproof layer on the laying surface of a support to be lined; first fixing of the waterproof layer on the support; covering the waterproof layer with insulating elements; fixing of the insulating elements on the waterproof layer.
  • the method is characterized in that the waterproof layer consists of a thermally adhesive membrane with an upper side and a bottom side which are parallel and oppositely arranged with respect to each other and in that the first and the second fixing steps are performed by means of heating of the upper side of the thermally adhesive membrane, the heating being able to cause adhesion of the insulating elements onto the upper side of the thermally adhesive membrane during the covering step and adhesion of the bottom side of the thermally adhesive membrane onto the laying surface of the support as a result of the heat transmitted from the upper side to the bottom side across the thickness of the said thermally adhesive membrane.
  • FIGS. 1-3 show in schematic form three successive steps for implementing the method for laying a waterproofing and/or thermally adhesive covering, according to the present invention
  • FIGS. 4 and 5 show in schematic form two further steps of the method in accordance with the above figures for laying a further waterproofing layer
  • FIG. 6 shows a schematic cross-sectional view of a thermally adhesive waterproofing membrane used in the method in question.
  • FIG. 1 denotes in its entirety an insulating covering arranged on a support 2 to be lined according to the method forming the subject of the present invention.
  • the support 2 may consist of any support used in the building sector and made, for example, from cement, concrete, wood, fretted sheet-metal or other material and may be used to form the base layers of roofs, floors, paving, horizontal or inclined walls, roadbeds, etc.
  • the method in question is intended to be advantageously used for the construction of thermally insulating and/or soundproofing and/or waterproofing coverings in particular for buildings.
  • the method envisages initially a step for preparing the laying surface A of the support 2 intended to receive the covering 1 , cleaning it if necessary by applying a bituminous primer and waiting for it to become completely dry.
  • the laying surface A traditionally undergoes a step for arranging a waterproof layer 3, as shown in Figs. 1 and 2.
  • This layer 3 allows the covering 1 to be protected against the moisture and vapour transmitted by the supporting base layer 2 and originating for example from inside the building.
  • a first fixing step for fixing the waterproof layer 3 on the support surface A of the support 2 a step for covering this waterproof layer 3 with an insulating layer 4, and a second fixing step for fixing the latter on the waterproof layer 3 are therefore envisaged.
  • the waterproof layer 3 consists of a thermally adhesive membrane with an upper side 5 and a bottom side 6 which are parallel and oppositely arranged with respect to each other. Moreover the two fixing steps are performed by means of heating of the upper side 5 of the thermally adhesive membrane 3.
  • the abovementioned heating operation causes adhesion of the bottom side 6 of the thermally adhesive membrane 3 onto the laying surface A of the support A because of the presence of thermal-adhesion polymers in the bituminous mixture and owing to the fact that the heat is transmitted from the heated upper side 5 to the bottom side 6 passing through the thickness d of the membrane 3.
  • adhesion of the insulating layer 4 arranged on the upper side 5 of the thermally adhesive membrane 3 during the covering step occurs while the membrane 3 itself is still hot.
  • this latter step must take place after the upper side 5 of the membrane 3 has been heated to allow the insulating layer 4 to adhere to the bituminous mass softened by the heat and preferably forming the membrane 3 as will be explained more clearly below.
  • the thermally adhesive membrane 3 advantageously consists of a thermally adhesive waterproofing membrane of the type intended to form dual-layer or multiple-layer waterproofing systems.
  • it comprises a first layer 3' of a thermally adhesive, elastomeric, bituminous mass arranged in the region of the bottom side 6 and a second layer 3" of bituminous mass arranged in the region of the upper side 5, able to allow the transmission of heat.
  • the production process will envisage, for example, impregnating and saturating a central reinforcement B (see Fig. 6) with a first layer of waterproofing bituminous mass and lining this layer on the two opposite sides with another two layers of bituminous material. More particularly, the layer intended to come into contact with the laying surface A will be mixed with thermal-adhesion polymers, while the layer intended to come into contact with the insulating elements 4 will be mixed with polymers (and/or with other substances) able to allow rapid transfer of the heat.
  • the insulating elements 4 consist of rigid or semi-rigid panels of thermally insulating material such as for example cork, expanded polystyrene, expanded polyurethane, wood, glass or rock wools or fibres, polyethylene or a layer of bituminous conglomerate.
  • the method of laying the covering 1 therefore envisages a first step for arranging a first layer 8 of waterproofing membranes onto the insulating elements 4 and a second step for arranging a second layer 9 of waterproofing membranes so as to line the first layer 8 (see Figs. 4, 5).
  • the two layers 8 and 9 of membranes are then fixed by means of a third fixing step intended to cause adhesion of the first layer 8 onto the insulating elements 4 and a fourth fixing step intended to cause adhesion of the second layer 9 on top of the layer 8 of waterproofing membranes.
  • thermally adhesive waterproofing membranes of the type described above it will be possible to perform the two fixing steps by means of a single operation involving heating of the upper surface 10 of the first layer 8 of waterproofing membranes.
  • heating causes adhesion of the bottom surface 11 of the first layer 8 of waterproofing membranes onto the insulating elements 4 as a result of the heat which is transmitted from the upper surface 10 to the bottom surface 11 , passing across the thickness d'.
  • adhesion of the second layer 9 of waterproofing membranes takes place, said layers being arranged on the first layer 8 during the corresponding fourth preparation step.
  • this latter step must be performed simultaneously or soon after the upper surface 10 of the first layer 8 has been heated so as to allow the second layer 9 to adhere on top of it under hot conditions, optimizing adhesion thereof.
  • Fig. 5 shows in schematic form the hypothetical case where the last layer 9 of waterproofing membranes is lined for example with slate scales 12, said layer being intended to remain visible and therefore also being required to perform an aesthetic function.
  • the invention thus conceived therefore achieves the predefined objects.
