Definitions

  • the invention relates to a method for repair building, whereby preferably the outer surface structure of a building or a like is repaired by arranging an essen ⁇ tially stiff structured facade element, such as a casing sheet, plate, thin-shell panel or a like in connection with the same, that covers the original outer surface and that is supported at a distance apart from the outer surface of the surface structure.
  • an essen ⁇ tially stiff structured facade element such as a casing sheet, plate, thin-shell panel or a like in connection with the same, that covers the original outer surface and that is supported at a distance apart from the outer surface of the surface structure.
  • a substance in liquid state is led between the facade element and the surface structure, wherein the solidi ⁇ fication of the substance into solid state, at least partly causes the installed facade element to stay in place essentially supported by the original surface structure.
  • the method according to the invention is applicable for repairing of facades made of most heterogeneous materials.
  • the invention has a particular meaning in repairing of reinforced concrete structures.
  • a parti ⁇ cular characteristic of such structures comprising usually a so called sandwich composition is so called carbonation.
  • Carbonation is caused by carbon dioxide that drifts inside the reinforced concrete structure, whereby the shrink steels inside the concrete get rusty, which is due to the neutralisation of the concrete surrounding the same.
  • By influence of the internal pressure effect caused by formation of rust it is usual, that particularly the steels situated close to the outer surface of the concrete split loose concrete above the same from the wall structure, whereby certain parts of the same become totally visible.
  • the phenomena in question is particularly harmful in the sense of esthetics, in addition to which the phenomena is harmful considering strength of materials, also, because corrosion of steel due to the carbonation may significantly embrittle the structure.
  • the steels in the concrete are uniformly surroun ⁇ ded by alkaline concrete, the type of phenomena due to corrosion described above may not occur.
  • each element transmit horizontal forces only.
  • a M 16 chemical anchor is appli- cable as a binder to be mounted on the supporting concrete structure. Accordingly the fixing of the bottom edge may normally be carried out for example by a M12 cotter bolt.
  • the method represented further in the patent document GB 2 097 457 is based on that, that to form a facade of a building or to repair the same, molds suitably shaped are being used, either separate ones or ones to be attached to the wall to be treated so, that after fulfilling of the casting mold an outer surface with desired patterning is achieved to the wall.
  • the solutions represented in this connection are thus meant particularly for facade maintenance by improving thermal insulation of the same or to achieve a desired decorative appearance of the facade to be repaired. It is not possible with these solutions either to improve the situation particularly for the part of car- bonisation of reinforced concrete structures or the like.
  • the method according to the invention is primarily characterized in, that particularly in connection with a reinforced concrete structure, such as a sandwich element or a like, a substance comprising at least an alkaline component, such as mortar, cement or like, is led into the space between the surface structure and facade element, which after solidification forms an alkalising intermediate layer between the facade element and the surface structure.
  • Simplicity and reliability of facade repairing enabled by the method according to the invention may be men ⁇ tioned as the most central advantages of the same. Thanks to the method according to the invention the most important thing, when keeping in mind parti ⁇ cularly the above reinforced concrete structures, is however, that it is possible to eliminate the effects of carbonation.
  • the alkalising substance being adapted acts thus as an intermediate layer, also, that glues the new facade element and the old surface structure to each other, thanks to which a reliable enough attachment of the facade element is achieved.
  • the new facade element may be supported by simple arrangements directly to the outer construction element of the original surface structu- re, in which case it is not necessary to remove the original structures as a whole or partly to enable attachments; naturally in this connection mass of the new facade element must be considered so, that for example the bearing capacity of the original hairpins is not exceeded.
  • it is thus advan ⁇ tageous to adapt casing elements having for example a so called metal cassette structure or exterior surface elements formed of an organic first base material, for example based on wood, pressed straws or like, and of an inorganic second base material for example based on stone, preferably by adapting cement as binder mate ⁇ rial, which do not increase significantly loads of the original structures.
  • the invention relates to a facade element applied for in connection with the method, also, that is represen- ted in more detail as two alternative embodiments in the preambles of the independent claims directed to each one of them.
  • the primary characteristics of the facade element are represented in the characterizing parts of the corresponding claims.
  • a crucial advantage of the facade element according to the invention is particu ⁇ larly the lightness of the same, which enables even repairing of facades being in a very bad shape by attaching the new facade to the casing part of the original sandwich element by an alkalising mass.
  • an alkalising mass When adapting a suitable substance as the alkalising mass, it is also possible to minimize casting pressures further so, that during the installation stage signi ⁇ ficant loads will not either be directed towards the facade to be fixed.

Abstract

L'invention concerne un procédé destiné à réparer un bâtiment, dans lequel de préférence la structure de la face extérieure (1) d'un bâtiment ou autre est réparée par la mise en place d'un élément de façade (2) à structure essentiellement rigide tel que tôle à revêtement, plaque, panneau en coque ou autre, relié audit bâtiment, recouvrant la face extérieure originale et supporté à une certaine distance (e) de ladite face extérieure de la structure superficielle (1). Une substance (v) à l'état liquide est placée entre l'élément de façade (2) et la structure superficielle (1), la solidification de ladite substance (v) provoquant au moins partiellement le maintien en place de l'élément de façade (2) installé, essentiellement supporté par la structure superficielle d'origine (1). En liaison, notamment, avec une structure en béton armé (1; 1'), telle qu'élément sandwich ou autre, une substance (v; v') constituée d'au moins un constituant alcalin, telle que mortier, ciment ou autre, est placée dans l'espace compris entre la structure superficielle (1; 1') et l'élément de façade (2), laquelle forme, après solidification, une couche intermédiaire alcalisante (v1) entre l'élément de façade (2) et la structure superficielle (1; 1'). L'invention concerne également un élément de façade.
