Definitions

  • the object of the present invention is a prefabricated panel for the building industry having the features of the prior art portion of claim 1, a process for the production thereof, and a method of using the panel itself.
  • the panel structure according to the invention has been conceived for the complete self-contained construction of a so-called “services area”, though it may find application, more generally, in the construction of all the inner partition wall of the building, especially in certain types of constructions as those intended for hotels.
  • service area is here meant the volume occupied by the bathrooms and kitchen which, according to the present invention, is concentrated around the piping system of the main installations - called also “technical block” - in a co-ordinate and functional whole.
  • a type of panel at present in use comprises for example slabs of gypsum board, fixed onto a supporting metal structure, with the eventual interposition of an insulating core, made for- example of rock wool. These panels are mounted onto a metal carrying framework, previously anchored to the concrete structure of the building. The connection points between adjacent panels are covered with gypsum smoothing.
  • a further known type of prefabricated panel having in turn a sandwich structure, comprises two sheets of thin laminated plastic - for instance of a thickness between ten and twelve tenths of a millimeter - containing an insulating layer, consisting for example of bakelized honeycomb board. Also these panels are mounted onto a metal carrying framework. The connection points between adjacent panels are covered by metal or wooden fillet joints.
  • these panels essentially have the advantage of providing a surface which - especially if used for partitions inside offices - can be considered as substantially finished.
  • Blocks of this type may generally contain, in addition to all the pipes and connections required for connecting the various sanitary apparatuses, drain traps, water drain and hot water tanks, conditioning or air ventilation systems, and/or electric systems.
  • Single-block cabin units thus realized are positioned in the building structure when it is still without partition walls, they are connected to the risers and drain pipes, whereupon curtain walls or sheathing or covering walls are leant against the rough walls of the cabin.
  • a first object of the present invention is now to realize a modular panel structure, being greatly improved compared to that of the known technique and providing, in particular:
  • the prefabricated panel structure according to the invention comprising two main slabs, glued together in spaced relationship by means of fillets arranged perpendicularly to surface of the slabs, so as to form a sealed flat box-like body, the chamber formed inside said sealed box-like body containing pressed insulating material, characterized in that said slabs and fillets are made of laminated plastic, consisting of sheets of high quality cellulose imbued with a mixture of phenolic resins superposed and pressed, said slabs having a thickness of at least 5 mm, and in that said fillets are arranged along a contour which is set back from the edges of said slabs.
  • At least one of the outer faces of said main slabs has a finished surface, so that once the panels -have been mounted in a partition wall construction defining a living space, there is no longer the requirement to complete or finish said watt, for instance with painting or wall-paper, as instead usually done in known technique.
  • a further aspect of the present invention consists in using the aforedescribed prefabricated panel structures in the building field and, in particular, for the construction of partition walls; for this purpose, one determines the perimeter of the partition walls defining different areas of a living space and, along said perimeter, one fixes to the ground a rest guide; the panels are mounted on the rest guide, providing to house the rest guide into the cavity formed between the spacing fillet and the bottom ends of the main slabs, the panels being furthermore mounted one next to the other, carrying into mutual engagement the respective vertical sides and using, time after time, flat panels, corner panels or T-connection panels up to completing the perimeter.
  • a compartment is formed along the vertical, side- by-side lateral edges, used for housing the service piping system, and/or along the horizontal edges, used for the fixing onto the rest guide fixed on the ground, or for the insertion of joints for anchorage to the ceiling.
  • the panel according to the present invention is formed by a pair of thick main slabs 1 and 2 of laminated plastic.
  • laminated plastic is meant at present a sheet product made up starting from sheets of high-quality cellulose, with high mechanical strength, imbued with a mixture of phenolic resins, superposed and pressed.
  • Such plastic laminates have been up to date produced in thicknesses usually notwiderthan ten to twelve millimeter tenths, and they have exclusively been used as sheets for covering and protecting a carrying structure, for example of wood.
  • the "thick laminated plastic” is a laminate produced substantially with the.same technique as described above, but sufficiently thick-for instance, 5to 12 mm-to become, to a more or less large extent, self-supporting.
  • a thick laminate of this type, though of very particular conformation, has been proposed in the Italian Patent application No. 24066 A/80 filed on 8th August 1980 in the name of the same Applicant.
  • the panel according to the present invention uses the two laminated plastic slabs 1 and 2, with the interposition of a layer 3 of insulating material, consisting for example of pressed cork. According to the invention, this insulating layer is delimited along its entire contour, by fillets 4, also made of thick laminated plastic.
  • Figures 1 and 2 show how to assemble the aforementioned elements 1,2,3 and 4.
  • the faces of the slabs 1 and 2 turning towards the inside of the panel are provided - to delimit the contour enclosing the insulating layer 3 - with grooves 1' and 2', into which engage the fillets 4 with their opposed edges (if the grooves 1' and 2' are wide enough) or, preferably, with ribs 4' formed on their edges.
  • the grooves 1', 2' and the ribs 4' are formed by milling, and this - taking into account the highly compact and hard structure of the laminate - allows an execution of high dimensional precision, to the full advantage of the subsequent assembly and gluing operations.
  • each pair of profiles is apt to engage, by simple cogging, with a pair of mating profiles formed on the opposite side of each adjacent panel (as shown particularly in figure 1).
  • This cogging allows to obtain a perfect airtight of joint coverings.
  • Figure 4 and 5 show how the panels are fixed one to the other into a wall structure.
  • a guide 5 is placed on the floor - firmly fixed by any known system, for example by riveting - comprising a metal rectangular section (as showm in figure 5) or an omega section, or the like.
  • each panel is positioned onto this guide 5, so that its bottom fillet 4 may substantially rest on the top of such guide, while the edges of the slabs 1 and 2, which extend beyond said fillet 4, embrace the guide 5 itself, as clearly shown in figure 5.
  • a first panel P Once a first panel P has been thus positioned, it will be simply anchored to the guide 5 with a bracket 6. This latter is fixed on one side, by means of a screw 7 or rivet or the like, to the top of the guide 5, and on the other side it is fixed to the vertical fillet 4 of the panel P by means of screws screwed into holes 6'.
  • the adjacent panel P' is positioned onto the guide 5 in the same way, being brought close to the panel P up to mutual connection of the cog rib profiles 4", so as to guarantee the correct anchoring of the panel P' to the side panel P.
  • the panel P' is then fixed with a bracket 6, in an identical way as described hereabove.
  • each panel is fixed to the floor with a single bracket, its correct anchorage being furthermore guaranteed by the cogging of the vertical edges of the single juxtaposed panels.
  • Figure 6 shows a panel forming a corner.
  • the fundamental structure is essentially the same as seen with reference to figure 1, that is, with slabs 1 and 2 of laminated plastic enclosing a thick layer 3 of pressed cork or other insulating material.
  • Each corner panel is however formed by two rectilinear panel parts, in each of which the contour of the insulating layer is defined by the heretofore described fillets 4 only on three sides of the panel, while in correspondence of the vertical corner side, the said layer is delimited by a wooden upright 8.
  • This upright 8 has a double function:
  • Figure 7 shows a panel in the form of a T or a double T connection.
  • This panel is usd, as better illustrated hereinafter, for the construction of a rectilinear wall, to which are perpendicularly connected other walls.
  • the main rectilinear panel P incorporates - in correspondence of the positions of connection to the walls perpendicular thereto - a wooden upright9, in replacement of the cork layer 3.
  • a lath 10, also of wood, is furthermore applied - by gluing or even by screws or other known suitable means - on the outer face of the panel, in correspondence of the upright 9.
  • the lath 10 is used as guiding element for a panel section 11, forming the beginning of a perpendicular wall, and it acts just like the guide 5 used to anchor the panel to the floor.
  • the section 11 is brought into engagement with the lath 10, so thatthe fillet 4 comes in contact with the lath and the ends of the slabs 1 and 2, extending beyond the fillet 4, can embrace the sides of the lath 10.
  • the panel section 11 thus results perfectly postioned.
  • opposed holes 12 and 13 are provided, at regular distances, on the fillets 4 of the section 11 itself.
  • a first smaller hole 12 is used for the passage of a screw 14 or the like, which anchors the section onto the lath 10 and onto the upright 9, while a second larger hole 13 is used for letting through a tool to drive in the screw 14.
  • corner panel as well as the T or double T panel, is assembled at the factory, and not in the building yard, whereby assembly can be done with the highest possible precision.
  • brackets 18 which are anchored directly to the ceiling at regualar intervals.
  • brackets 18 may be simple L-shaped metal brackets.
  • brackets made of rubber or similar resilient material adapting more easily - by mere elastic deformation - to the distance differences between the ceiling and the top of the panels.
  • the space lying between the top of the panels and the surface of the ceiling isfilled with insulating material L, for example rock wool.
  • insulating material L for example rock wool.
  • Both sides of the double wall thus formed are then closed by masking frames 19.
  • the frames 19 may have any configuration and be fixed by any suitable means of known type, whereby it seems unnecessary to give a detailed description of such means.
  • the intermediate space between the panels forms a practically sealed air chamber.
  • the panel according to the invention provides furthermore very precise and uniform dimensional and qualitative characteristics, and this considerably facilitates the assembly operations in the building yard. It has been found in practice that, for constructing for example a bathroom, the construction time is reduced up to 70% compared to the traditional systems.
  • the aforecited dimensional and qualitative characteristics are permanent in time, whereby there is no fear at all of any yieldings or deformations.
  • the panel is in fact resisting to impact, abrasion and chemical etching; it is liquid-proof and thereby perfectly resisting to dampness which is normally present in sevices areas; it is furthermore quite fire-resisting.
  • the panels according to the invention have a good soundproofing or deadening power. With a panel of the type illustrated in figure 1, about 40-50 mm thick, an absorption of about 32-35 db has been observed, while a wall with two panels, as the one illustrated in figure 12, has been found to provide an absorption up to 48 db.
