Definitions

  • the invention relates to a method for the production of a blanket and a blanket produced according to the method.
  • a ceiling to be made by pouring concrete so first a casing is provided. Rectangular formwork elements are set up with supports from the ground underneath. The formwork elements then form an area which is arranged parallel to an underlying floor. But it is also possible that the surface is inclined.
  • Shuttering elements have, for example, an OSB board with a frame made of aluminum, which protects the board from damage.
  • the supports can be made of steel or aluminum.
  • To set up a formwork element for example, a support is used for each corner, so a total of four supports. The length of the columns can be changed.
  • the extension panels are correspondingly thick woods, cut to size and placed in the spaces between formwork panels.
  • the surface formed by the flattening and extending panels is framed by shuttering elements mounted perpendicular thereto. Now concrete can be poured in to make the ceiling. If a ceiling has been produced, protruding ridges and other impressions remain in the region of the transitions from one shuttering element to the next or from a shuttering element to an outer panel. Because of these bumps, a blanket is in the rain! plastered, then the ceiling can be painted, for example.
  • each surface consists of a plurality of contiguous surface elements on its side adjacent to the ceiling to be cast ceiling.
  • the surface elements may be the shuttering elements, but are preferably separate surface elements which are placed on the shuttering elements or attached thereto. Due to the transitions from one surface element to the next, as in the prior art, gaps or scratches remain between two surface elements. In contrast to the prior art, these transitions are now glued or covered over on the side adjacent to the cover to be produced or hang up narrow strips can be used. The easiest and best is to stick with a band, as it is commercially offered for example by the company Beiersdorf from Germany.
  • plates are applied to the shuttering elements, which are made of plastic.
  • the panels can only be laid onto the formwork elements in the event of a ceiling being broken.
  • the panels are placed so that they abut closely against each other to form a surface.
  • the advantage is that plastic panels can be cut easily. It is thus possible, regardless of the dimensions of a ceiling and a wall to provide the necessary casing completely through the plastic sheets. Apart from the transitions, a uniform surface can be created by casting alone be obtained from concrete. Kunststoffstotfplatten can otherwise be used repeatedly several times, If a plastic plate replaced due to a damaged surface or can not be used again, so arise only comparatively low cost and in particular compared to the case that a Verschalu ⁇ gselement must be replaced due to a defective surface ,
  • Such a plastic plate can be very thin, for example, only 3 to 7 mm thin. This reduces costs and simplifies trim when required.
  • the plastic plates used have a middle layer which is reinforced with fibers, in particular glass fibers. This ensures that the plates by weathering, such. B. not forgiven by a strong sunlight or by very low temperatures, It is guaranteed as a uniform result in the production of blankets.
  • Such a middle layer is coated in particular with polypropylene.
  • a suitably smooth, sufficiently resistant surface can be provided.
  • the supports for example made of tubular steel, are connected to one another by spacers.
  • the spacers are preferably made of a thread.
  • DYWIDAG threaded rod is used.
  • the threaded rod is firmly connected at one end with a vertically projecting mandrel.
  • the mandrel is inserted through a designated hole of the support.
  • a clip is provided around the mandrel. If the mandrel is pushed through the hole in the support, then the clamp clasps the support at the same time.
  • the spacer is positively connected to the one side with a support.
  • An appropriate one Mandrel and clamp is attached to the side of a screw sleeve.
  • the screw sleeve is screwed onto the thread, and it is adjusted so the distance, Thereafter, the mandrel is passed through a corresponding further hole of another support and so the other side of the spacer positively connected to another support due to the clip.
  • the spacers are preferably mounted 1, 50 m to 1, 80 m above the ground. On the one hand, the spacers can then be attached to one another. On the other hand, a sufficient stability of the framework together with the shuttering is achieved at a normal height of the ceiling.
  • the aforementioned supports are provided with heads that are provided with sliding elements.
  • the displaceable elements can be moved horizontally in the erected state of the supports in a desired position and then fixed in this position.
  • the displaceable elements can also be connected to it supported or stored preferably form-fitting shuttering elements, so that a displacement of a surface element or, Verschalungseiements relative to the displaceable element in the horizontal direction is no longer possible, This is achieved for example by one or more protruding thorns of the displaceable element , from below into holes provided for the respective shuttering element can be put into it. Dismantling is no longer necessary to ensure mechanical stability of the construction.
  • each head can be mounted sufficiently stable on each support.
  • Such a head is also preferably adapted to provide a horizontal surface thereon in the assembled condition, to which it can be placed, preferably between two displaceable elements or adjacent to a displaceable element of each head. If large-area plates, for example made of plastic, are deposited on the shuttering elements, such spacers may, if necessary, support these (plastic) plates in intermediate spaces which remain between two shuttering elements. Drawing boards can be omitted, which saves time and money.
  • the large-area (plastic) plates have stapling devices. These staplers are placed around the edges of underlying shuttering elements and so the plastic sheets are attached to the shuttering elements.
  • a plate having a middle layer of metal, such as aluminum.
  • the metal layer is then preferably coated from both sides with a suitable plastic such as polypropylene.
  • a suitable plastic such as polypropylene.
  • a fiber reinforced middle layer plate has been found to be more suitable.
  • a plate consists of two fiber-reinforced cover layers and a middle layer.
  • Such a particularly suitable plate is commercially sold by the company Isosport under the name "iaminaeX ® w . More preferably, the thickness is 5, 7 mrn or more. If such a plate is at least 5, 7 mm thick, distances of up to 30 cm can be covered in housing construction. This applies to ceilings with a thickness of up to 20 cm, which are common in residential construction.
  • the transitions are sealed with an adhesive tape that has grown in all weather conditions, ie wetness, dryness, solar radiation and so on.
  • the tape prevents burrs from forming. Instead, there is a slight imprint in the ceiling when it has been poured. These impressions can be easily filled with a spatula, otherwise the blanket is so even that it can be painted immediately. It is no longer necessary to plaster such a ceiling,
  • the invention not only plastering can be avoided.
  • the shuttering can be provided much faster compared to the prior art in the case of a ceiling, because with a circular saw or a table saw with a vidia sheet, the plastic plates can be cut quickly compared to the wood panels, especially since only a suitable compensation must be cut. Otherwise, standardized plastic plates can be used.
  • the ceiling may have been provided next to concrete with usual further reinforcements, so with steel mesh.
  • ceilings are formed which differ from prior art band-shaped recesses.
  • the depressions are regularly less than 1 mm deep and only a few inches wide, such as 3 to 8 centimeters.
  • the band-shaped depressions usually form rectangles, thus surfaces are framed, which are free of Strukturieru ⁇ gen or ridges, so form a desired smooth surface,
  • Figure 1 shows a plan view of a masonry]. You can see the formed from rectangular plastic plates 2 surface that serves as a shuttering. Edge regions of the formwork are filled with trimmed Kunststoffpiatten 3, 4 and 5, There remain column 6 between the individual plates 2, 3, 4 and 5, which form the transitions. A transition is already pasted over with a smooth, 0, 1 7 mm thick fabric tape 7 made of synthetic fibers with a tensile strength of 1 78 N / 25mm and an elongation at break of 9.5%. A natural rubber serves as an adhesive, which is temperature resistant up to 40 ° C. Such an adhesive tape can be obtained commercially,

Abstract

L'invention concerne un procédé pour la réalisation d'un plafond ainsi qu'un plafond réalisé par ce procédé. L'invention permet de réaliser des plafonds améliorés. Pour atteindre cet objectif, on prépare des surfaces à l'aide d'éléments de coffrage pour la coulée d'un plafond, chaque surface étant composée, sur sa face adjacente au plafond à couler, d'une multiplicité d'éléments de surface mutuellement adjacents. Les éléments de surface peuvent être les éléments de coffrage. De préférence, ce sont des éléments de surface séparés qui, dans le cas d'un plafond, sont posés sur les éléments de coffrage ou fixés à ceux-ci. Aux jonctions entre un élément de surface et le suivant, il subsiste des fentes comme dans l'état de la technique. À la différence de l'état de la technique, ces jonctions sont à présent surcollées ou masquées notamment sur la face qui est adjacente au plafond à réaliser. Pour le surcollage ou le masquage, on peut employer des lattes étroites. La façon la plus simple et la meilleure consiste à effectuer le surcollage avec une bande.
