Definitions

  • This invention relates to a heat insulating board for a pillar or a beam of a building as described in the preamble of the main claim.
  • the pillars and beams placed along its outer walls may operate as thermal or single bridges through which the indoor heat of the building dissipates in the surrounding outdoor environment.
  • Such dissipation clearly influences the indoor temperature of the building and the operating costs of its heating plant.
  • damp stains leading to alarming inconveniences, especially from the aesthetic point of view may emerge in areas corresponding to such pillars or beams.
  • pillars or beams are insulated by means of insulating boards which normally are made of foams, such as extruded or expanded polystyrene foam, polyurethanes foam or chipboard.
  • foams such as extruded or expanded polystyrene foam, polyurethanes foam or chipboard.
  • Such boards allow a proper insulation of the above-mentioned pillars and beams, however they create a problem insofar as they are not easily shaped with the same dimensions of the faces or sides of the pillars or beams to be paneled.
  • portions of oversized insulating boards are often used (with all the waste of insulating material ensuing therefrom), or the above-mentioned shaping operations frequently lead to breaks in the insulating board, which consequently may no longer be used.
  • Insulating boards are widely known, which are provided with numerous mutually equidistant grooves on at least one of their faces, but preferably on opposite faces one of which is meant to come directly into contact with the pillar or beam to be paneled.
  • the function of such grooves is to increase the surface on which mortar (or similar material) is laid, thus acting as a "bonding agent" to fix the insulating board to the pillar or beam.
  • such grooves do not allow an easy separation of the latter into two parts (being adjacent and separated by a groove), either manually or by means of a dedicated tool as a cutter.
  • the object of this invention is to provide a heat insulating board for the paneling of pillars or beams of buildings that may be easily divided into portions whose dimensions correspond to those of the surfaces to be paneled and insulating, with particular reference to the usual and standardized faces of pillar and/or beams.
  • a further object is to provide a board of the above-mentioned type which may be divided into ad-hoc sized units modules, both by means of the usual cutting tools and manually.
  • a further object is to provide for a board of the above-mentioned type which may be used to panel pillars or beams whose dimensions exceed the usual or standardized measures.
  • a further object is to provide a heat insulating board for pillars and beams which may be mass-produced at reduced costs.
  • this invention relates to an insulating board which is meant to be used in particular for the paneling of at least one side of the pillars and beams of buildings, so as to insulate the paneled face or side of such pillars or beams, wherein such board comprises a main body provided with two opposite surface, one of which is meant to be fixed to the above mentioned face or side, and four perimetric sides; characterized in that at least one of the above-mentioned opposite surfaces is provided with a least one first groove parallel to at least one pair of perimetric sides of the insulating board, such first groove being placed at a predetermined distance from one of such perimetric sides equal to the distance between the opposite extremities of the side of the pillar or beam to be paneled; the groove being sufficiently deep to allow the separation of two adjacent portions along it, manually or by means of a cutter, and being narrow to create a substantially even separation surface, and in that the board comprises at least one additional groove that is orthogonal to any groove and is placed within at least one surface of the
  • Figure 1 is an exploded view of a possible application of this invention with reference to pillars.
  • Figure 2 is a perspective view of a phase of the application of this invention.
  • Figure 3 is a zoomed-in view in direction of arrow K of Figure 2 of this invention.
  • Figure 4 is a top view of a different embodiment of this invention.
  • Figure 5 is a top view of a further aspect of this invention.
  • a heat insulating board is generically marked 1 and is meant to be fixed to at least one face 2 of a pillar 3 or of a beam 4 of a building.
  • face 2 of a pillar 3 or of a beam 4 of a building Preferably and usually such face is the external one, that is, that facing the external surface of the building itself.
  • Board 1 is made of materials usually employed for insulation, such as foams (extruded polystyrene or expanded polystyrene foam, polyurethane foam) or chipboard. Moreover it is fixed to face 2 according to the usual methods by means of mortar or other building material.
  • the above-mentioned board comprises a main body 5 being modular provided with wide opposite surfaces 6 and 7 and four perimetric sides 8, 9, 10 and 11. Surfaces 6 and 7, one of which is meant to come directly into contact with the pillar or beam (for example, number 6 in Figure 1), may be even (as in Figure 4) provided with wide grooves 13 parallel to sides 8 and 10 and following each other in an orderly way. In the case under discussion, such grooves have a width x amounting to about 1 cm and an average depth of about 2 mm.
  • board 1 comprises (in the embodiment shown in the drawings) numerous continuous grooves 15 which are meant to be mutually opposite on both surfaces 6 and 7 or they may be present only on one of such surfaces, but they are consecutive and mutually equidistant in any case.
  • Each of such grooves has such dimensions so as to allow an easy manual separation of two parts 1A and 1B from board 1, thus creating sufficiently even separation surfaces.
  • the last terms means substantially even surfaces that at most bear projections having a very limited height - within a range of few millimeters - which do not influence the use of board 1 as an insulator of a pillar or beam anyhow.
  • the grooves 15 are mutually parallel and are also parallel to the longer sides 8 and 10 of board 1 (that is, parallel to the any grooves 13 envisaged on surfaces 6 and 7 of the board itself). They are mutually equidistant, preferably with a mutual distance B amounting to a value equal to a submultiple of the dimensions of the pillar. Usually the grooves are preferably placed at mutual distance of 5 cm, so that multiples of such figure may be calculated, thus reaching values equal to the usual dimensions of a pillar or beam.
  • each groove 15 determines a cutting line on board 1 and its width A ranges from 1 to 2 mm (that is,. a width similar to that of a cutter so as to provide a sufficiently precise track for the latter across surfaces 6 and 7).
  • width A which has the above-mentioned measures, allows the separation of portions 1A and 1B of board 1 by means of the simple manual bending of the latter (arrow z Figure 2) along one of the grooves 15.
  • each groove 15 has a sufficient depth D which is related to the thickness S of board 1 and to the type of material that is used.
  • the total depth of grooves 15 envisaged on the above-mentioned board that is, the sum of depths D of two opposite grooves such as, for example, in Figure 3, or the depth of a single groove envisaged on only one of surface 6 or 7) ranges from 6 to 14 mm.
  • Said board has an initial transversal dimension (that is, measured in a parallel way to sides 9 and 11 of portions 1A, 1B illustrated in Figures 1 and 2) superior to L, for example twice as much.
  • ten grooves 15 starting from the free border (marked 10 in Figure 2) of board 1 are to be skipped.
  • board 1 is to be bent (arrow z in Figure 2) along the last groove, thus achieving the separation of the above-mentioned portion from the rest of said board.
  • such separation may be achieved by means of a cutter operated along the selected groove 15.
  • insulating boards 1 of any preselected size may be easily created thanks to this invention, since the possibility emerges - according to an approximation to the nearest greater or smaller whole number - of calculating the size of face 2 of the pillar (or beam) to be paneled, or an adequately similar value, between two consecutive and adjacent grooves 15 on board 1.
  • the separation of a portion of the selected size may be easily carried out by means of a cutter. This is very easily done with board 1 of Figure 4. Between each groove 15 and the adjacent grooves 13 there is an even area 20 with a width F amounting to 2 cm.
  • board 1 may be divided by means of a cutter. This cutter moves across board 1 in a parallel direction to grooves 15 so as to separate portion 1A or 1B, it measuring the requested length L, from such board.
  • board 1 comprises numerous grooves 30 that are orthogonal to first grooves 15, placed at a distance H1, H2, H3 and H4 ( in the example) from side 9 of the main body 5 (that is, a shorter side) and equal to different standardized heights of a pillar (or lengths of a beam).
  • Such grooves have the same characteristics and dimensions as the above-mentioned first grooves 15. For simplicity's sake, such characteristics will not be dealt with again.
  • the application of the aspect under discussion is simple; after length L of the pillar (or W of the beam) has been determined, the portion of board 1 that is sufficient to panel face 2 of said board (or beam) may be separated following the procedures described hereinbefore.
  • opposite first grooves 15 measuring different depths D may be envisaged on surfaces 6 and 7 of board 1; however this may be done while maintaining the total depth of such grooved areas within values which do not jeopardize the mechanical resistance of board 1 in the adjacent parts to such grooved areas.
  • first grooves 15 as illustrated by way of information in Figures 1, 2, 3, and 4 may be placed at a distance equal to a multiple or submultiple of 5 cm, for example, 2.5 cm or 10 cm. Distance selection depends on employment conditions and on the most common measures referred to during the manufacturing of pillars and/or beams for buildings.
  • the usually preferred measure is 5 cm.
  • the length of board 1 may measure twice the width L of pillar 3; consequently, said board may be provided with one groove 15 only placed, for example, at a distance (equal to a multiple of 5) equal to 50 cm from sides 8 and 10, that is, at such a distance so as to allow the separation of two portions 1A and 1B measuring length L equal to that of the relating pillars.
  • grooves may be mechanically crated by removing material by means of milling cutters normally used for wood and other similar materials, whereas only in the case of polyurethane and polystyrene foam, grooves may be achieved through molding procedures, that is, through expansion of the materials inside predefinite molds having the same (negative) measures of the board to be manufactured.
