Definitions

  • HU-A-173 309 "Method and installation for building structures", is also known; In the sense of the known proposal, the mass production of components of different dimensions is solved by setting the components and the adjustable production systems "in a double reference system".
  • the disadvantage of the first solution can be seen in the large number of auxiliary structures used for adjustment and in the demanding work involved in the adjustment, the advantage, however, is that the dimensional tolerance of the reinforcement can be easily coordinated with the dimensional tolerance of the formwork elements.
  • An advantageous characteristic of the second solution consists in the extensive reduction in the use of auxiliary structures; on the other hand, it is disadvantageous that the reinforcement is relatively overdimensioned, overdefined.
  • the dimensional tolerance of the reinforcement and that of the formwork elements are linked to each other, which leads to an excessive increase in the concrete cross-sections, which in turn makes it unlikely that the elements bound to the pre-assembled, welded iron skeleton will be cast in concrete without support or that the skeleton will be oversized.
  • a common disadvantage of the methods is the high number of constructions to be coordinated and the poor accuracy (production system, formwork elements, reinforcement, auxiliary construction installed on site, welded iron skeleton mounted on the construction site); a further deficiency is that the mutual precise arrangement of the mold formed by the inner surface of the formwork elements and the reinforcement has not yet been able to be solved, which is extremely important from the point of view of the small concrete cross sections and the continuity of the concrete coverings. An enlargement of the concrete cross sections or an oversizing of the reinforcement can lead to the loss of the favorable conditions of the construction.
  • the invention has for its object to provide a formwork for thin-walled reinforced concrete structures with precise dimensions and to design so that it can be assembled quickly and easily.
  • multipurpose spacer inserts are used in the hygroscopic formwork elements which form the surface of the construction and are generally made with gypsum as a binder, and the spacer inserts are based on the precise determination of the relative position of the steels to be inserted, the concrete and the formwork elements, the coordination and anchoring thereof are associated with assembly technology and / or static and / or building physics advantages, thereby making it possible to achieve the set goal.
  • the cavity system of the dry-assembled self-supporting surface construction which was created in this way and is delimited with formwork elements, is poured with low-viscosity concrete mortar.
  • the auxiliary structures used for adjustment (assembly) are unnecessary, since the reinforcement threaded through the spacer inserts combines the formwork elements into a single surface; at the same time, the exact positioning of the reinforcement at the predetermined location in the concrete cross-section is guaranteed.
  • the dimensional tolerance automatically adapts to the formwork elements. Determining the position of the reinforcement with the utmost precision creates the basis for refining the static planning and dimensioning (concrete covering is constant and uniform, corrosion and displacement in an unfavorable direction are excluded).
  • the spacer inserts embedded in the formwork elements can be made of different materials and of different shapes. A common characteristic is that they do not corrode, the desired location of the steel inlays is determined by the perforation of the inlays, the connection with the formwork elements is rigid, they can be produced with methods of high productivity.
  • connection between the reinforcement and formwork elements enables the following assembly methods: threading, snapping, hanging and bracing. If necessary, the spacer elements meet all requirements in connection with the spacing (doubling), the stiffening of the formwork elements, the shape of the concrete cross-section and the heat and sound insulation.
  • the spacer elements take part in the provisional load transfer (e.g. stiffening of the formwork elements) or in the final load transfer (e.g. bracket) or they support the steel inserts against shifts in the transverse direction; if necessary, the formwork elements bear the load.
  • the formwork elements have a flat outer surface; the inner surface is either flat or profiled. The size and weight are adapted to the manual material movement.
  • the following characteristic forms of the building constructions can be produced: reinforced concrete shells, ribbed plates, folded plate works, lattice works, box-like constructions, constructions with saving cavities.
  • Spatial constructions can be assembled from the flat surfaces with cell structure; If the open or closed cavities of the constructions are dimensioned accordingly, they can be made suitable for solving building physics tasks, for the purposes of installation technology, home furnishings.
  • the first manufacturing phase of the double-shell formwork element is the same as that of the single-shell formwork elements with the addition that in the second phase of manufacture the already set, provided with the spacer inserts first element is immersed with them in a plastic mass with gypsum as a binder.
  • Double-shell formwork elements are generally used to erect vertical surface structures. As can be seen from FIG. 7, the elements lined up next to one another are combined with horizontal and vertical steels 4 and 5 threaded or snapped into the spacer inserts 2 as reinforcements. Holes 7 are formed on one of the mutually perpendicular formwork elements along the connecting line. The reinforcement threaded through the holes or the concrete flowing through connects the two elements. A surface of the desired size can be put together from the elements, with the reinforcement being passed through the elements in the required number.
  • Single-shell formwork elements 1 are generally used for horizontal surface constructions.
  • connection of the vertical and horizontal formwork elements was designed similarly.
  • the horizontal reinforcement 4 is threaded into the spacer inserts 2 of the horizontal single-shell formwork element 1, which, threaded through the holes 7 of the vertical double-shell formwork elements 3, rests on its horizontal reinforcement 4.
  • the reinforced formwork elements in the vertical direction of the dry-mounted stable construction without support are poured out with thin concrete mortar 6 with a fine grain structure, or the concrete mortar 6 is spread on the horizontally positioned formwork elements.
  • the spacer insert not only stiffens the formwork elements, but also functions as a final load-bearing steel insert.
  • the spacer insert is a spatially curved galvanized iron mesh, the length of which corresponds to that of the boarding plaster element, or a perforated sheet metal strip is used for this purpose. In this way, it is generally sufficient to thread the rectified horizontal iron wires 4.
  • the latticework 8 increases the span limit during assembly several times without support.
  • the spacer insert 9 is prefabricated from a profiled compression-molded synthetic plate made of foam or silicate foam.
  • the two-way duct system with the wedges and holes that hold the reinforcement at a suitable distance is ideally suited for holding the steel inserts and for holding them up in an exact position.At the same time, a material-saving lattice structure is created, which increases the heat and sound insulation properties of the surface structure with a foam spacer insert.
  • the pressure of the poured or spread concrete is compensated for by the spacer inserts, which are combined with the reinforcement and hygroscopic formwork elements. Due to their solidification ability, they suck off the excess water to set and guarantee automatic post-treatment by keeping the concrete structure moist.
