Definitions

  • This invention concerns shuttering for the fabrication of two-slab panels.
  • the invention deals with shuttering. which is employed in a coordinated manner to make composite.
  • building structures which consist substantially of electrically welded mesh incorporated in castings of cemented comglomerate and which are anchored together with suitable trelliswork so as to form structures with plane-parallel slabs separated by hollow spaces that can be filled advantageously for given purposes with thermally insulating and/or sound absorbing materials.
  • This invention refers in particular to shuttering charac - terised by new structural and practical solutions.
  • Double slabs are known as also are diverse devices and means to make them.
  • SARTORIO which describes a device and procedures for fabricating and applying constructional building elements.
  • Said building elements are made substantially with an automatic device working with a continuous cycle and comprising a movable surface, equipped with lateral forming rings, on which said building elements are formed.
  • This automatic device involves many drawbacks.
  • One of them lies in the fact that the movement itself hinders the performance of the operations to be carried out in making the building elements.
  • a futher drawback is that the manufacture of several elements on one single working surface can lead to interference in the various operations or tasks to be done on said surface. Moreover, said patent does not indicate all the functional elements required.
  • the purpose of said improvements is to make the double slabs by immersing both a mesh suitable for embodying the core of the slab and also spacer elements in a mass of cemented material already deposited on the movable working surface but not yet solidified.
  • This device too desides being substantially utopian, requires a very fluid cemented mass to enable the mesh and spacer elements to be.immersed therein and reveals many drawbacks and shortcomings which make it difficult to apply.
  • Patent application IT 25325 A/77 once again in the name of SARTORIO, has been put forward, wherein a system is substantially envisaged for bonding together neighbouring two-slab panels; a special panel is also visualised which resumes substantially an old patent IT 713072 in the name of SARTORIO.
  • DE-OS 2611843 Another type of shuttering is disclosed in DE-OS 2611843. which consists of a bottom plate for casting one concrete slab in which is encased the metal mesh and trelliswork projecting therefrom and a top frame provided with support legs which is placed on top of, and separated from the bottom plate
  • the top frame is provided with a removable bottom consisting of a plurality of boards arranged longitudinally between the trelliswork which project therefrom in the spaces provided . between the boards.
  • Said boards are kept in place by a number of traverse bars terminally suspended from the edge of the ton frame.
  • the top frame After casting the bottom slab and arranging the metal reinforcement, the top frame is placed on top thereon and the removable bottom is constructed from the the longitudinal boards and the travese bars. The top frame is then ready for casting the top concrete slab.
  • patent application IT 83345 A.78 in the name of the present author, which describes a device for the embodiment of double slabs made by vertical removal of the upper shuttering suitable for forming the second slab.
  • This device is especially restrictive if it is used in working surroundings of small dimensions.
  • This invention envisages an embodying solution which is simple and at the same time very effective.
  • the purpose of the present invention is to embody a device for fabricating two-slab panels which is simple and effective which requires no lengthy and laborious setting-up and dismantling operations.
  • said device must be able to be embodied by using existing structures already employed in the fabrication of simple slabs.
  • a further purpose of the invention is to embody a device which does not require excessive controls or maintenance work but which ensures excellent performance at the same time.
  • a purpose of this invention is to embody a device which ensure the parallelism of, or a possible preset angle of inclination between, the flatslabs constituing the panel moulded, and also the ability to repeat the operations within very narrow limits of tolerances.
  • Yet another purpose is to embody a simple and effective device for removing the shuttering.
  • the invention is embodied, therefore, in shuttering for the fabrication of two-slab panels, whereby the double slabs consist of two layers of vibrated, cemented conglomerated material incorporating electrically welded metallic mesh cores and linked together with flat trelliswork so as to form panels for building work, whereby there can be insulating or non-conducting means in the double slab, said shuttering.
  • said shuttering being characterised by comprising in coordinated cooperation with a surface for moulding single slabs:
  • Fig. 1 shows a surface for forming flat slabs 10, to which is fitted a surface 110 consisting of shuttering means 16 ' such, according to the invention, as to make the whole suitable for forming the double slabs, said surface 110 forming the . bottom surface of shutting means 16 which is provided with . a plurality of longitudinal slits 23 and at least one removable end plate means 19.
  • the shuttering 16 and end plate means 19 are generally preassembled in advance.
  • the surface for forming flat slabs 10 is a normal surface mown in itself and already available with manufacturers of simple slabs.
  • the forming surface-10 is installed rigidly on a supporting structure 11 cooperating with vibrating means 21 or other means suitable for the purpose.
  • the forming surface 10 has fixed 120 and movable 20 side panels able to be positioned as desired for delimiting and conforming the perimeter of a single slab.
  • the single, or first, of the two slabs comprising a double slab is made on said forming surface 10 in a known manner, care being taken to pre-arrange and position the necessary flat trellises.
  • removable support elements 15 are put on the edges of said forming surface 10.
  • Said support elements 15 can cooperate with suitable means of the right size for quick or automatic positioning, or else can be already fixed, or at least caused to be fixed temporally, to the surface 10.
  • the support elements 15 comprise two pins 17 which are advantageously threaded and to which it is possible to fit one or more components of composite spacer means 12 (illustrated in Fig. 3) so as to obtain the required height of the empty space between the two slabs.
  • removable support elements 15 One of the advantages of the use of removable support elements 15 is that the distance between the centrelines of the various composite spacer means 12 provided on each support element 15 is registered and carefully determined in advance in a workshop so as to offer precise centering of the spacer means 12 and between the corresponding threaded holes in the upper shuttering.
  • a second advantage is the fact that it offers a simple operation for removing the composite spacer means (2) when necessary.
  • Each component 112 of said composite spacer means 12 can include knurled areas to facilitate handling, and also . possible holes 24 (or like means) where the required motive. force can be applied that is necessary for the proper engagement of said means 12.
  • the component of composite spacer means 12 have various . heights so that, in combination with each other, they can be adapted to various requirements; they also comprise male 14 and female 13 coupling means,preferably threaded.
  • the male coupling means 14 of the spacer means components 112 are located at the top thereof and serve in our example. to position the shuttering means 16.
  • each composite spacer means 12 consists of a plurality of components 112 of substantially different heights, arrangeable in columns, each component 112 being provided with a threaded hole 13 on one side and a thread stem 14 on the opposite side, whereby the threaded stem 14 of one component engages the threaded hole 13 of the next component in the column and the threaded hole 13 of the bottom component 112 of a column being engaged by the threaded stem 17 provided on the removable support means 15 while the threaded stem 14 of the top component l12 6f a column engaging the threaded hole 18 provided in the shuttering means 16.
  • the shuttering means 16 consistsof a plurality of tubular or C-shaped elements of which the upper side constitutes the moulding surface for the second slab.
  • the shuttering means 16 form with end plate means 19 a rectangular mould having a bottom 110 provided as previously mentioned with longitudinal slits23.
  • Said slits 23 serve for the passage of the flat, trelliswork, intermediate, distancing uprights of the double slab.
  • Each slit 23 is closed temporally by elastic means 123, . so that said elastic means, in the example rubber strips, do not allow the cemented conglomerate to pass through-said. spaces 23.
  • the shuttering means 16 can also be equipped for the passage and distribution of steam; in this case holes 216 are envisaged for proper distribution of steam so as to improve the action of drying and curing the product.
  • the end plate means 19 is terminally and trasversally connected to shuttering means 16.
  • Said plate means 19 can be connected mutually with bolts pins 119 or other removable means, which facilitate the rapid removal of said end plate means 19.
  • top shuttering 16 has only one removable end plate means 19 at one end thereof, the rest forming one solid unit.
  • the fixed and movable side panels 20-120 lie on the shuttering surface 110.
  • the shuttering surface 110 When the lower layer of the double slab has been moulded on the forming surface 10, the shuttering surface 110 is installed, the mesh (Fig. 2) is put on said shuttering surface 110, care being taken to anchor it to the flat trelliswork means, and the concrete is then cast.
  • the casting is levelled and is perhaps vibrated.
  • the fixture pins 26 cooperate with the holes 18 of the end plate 19 which, for this reason, is now disconnected from the shuttering means 16.
  • a winch 29 is then connected to the free end of shuttering 16.
  • the shuttering runs on upholding means 30, which may consists of a bed of rullers.
  • the table 25 that withdraws the mould can be manifold according to the invention.
  • each threaded stem 17 can have a separate support conformed differently; it is also possible to visualize that the support elements 15 and; in substance, the composite spacer. means 12 are arranged lengthwise on the side edges of the fixed mould 10 and, therefore, that the seatings 18 of the . shuttering 16 are machined laterally so as to cooperate with said composite spacer means 12.
