Definitions

  • the invention relates to a corner protective means for walls, beams, columns etc. with an arc shaped front and two integrally formed wings, said wings extending from two edges of said arc shaped front, permitting the wings to extend in a direction substantially parallel to a wall surface of a corner over which said means is installed, whereby said wings have protrusions and a bent tail formed at their free ends each, which is directed further into the wall surface.
  • corner protective means for instance the device for aiding the production of surface finishes described in the GB-A-2 056 523 or the DE-U-7 933 290. These corner protective means are inconvenient in installation, of inferior quality, of low performance and becoming loose easily.
  • the device described in the preamble of claim 1 and disclosed in the GB-A-2 056 523 for instance is not engulfed by the concrete of the wall, but only the tails of said device are anchored in the wall. Further, the device provides no measures for ensuring a smooth wall surface which is flush with the edges of the arc shaped front of the corner protective means. This is neither practical in use nor desired by architects.
  • the second known art, the DE-U-7 933 290, describes also only a device for the easy installation of tiles.
  • the device can not spread forces over sufficiently great areas in the wall, which causes the problem of the elastical material breaking out of the rigid plaster coating.
  • Both known devices are provided with area-holes to ensure their connection with concrete or plaster. Area holes allow the concrete to form bridges between both sides of the device. During shrinking of the concrete there occur however cracks in the same.
  • a corner protective means which has a generally arc shaped front and two wings extending from said two edges of the arc shaped front to form a generally right angle, and may be inserted into the concrete before the final finishing of the walls, beams, columns etc., so that it may firmly grip the concrete structure.
  • the corner protective means 1 of the invention generally has an arc shaped front and two wings 10 extending outward from a direction given by prolonging the ends of the front in a straight line from the two edges of the arc shaped front.
  • the wings 10 are generally symmetrically formed, so that the description of one wing shall represent both wings in the specification.
  • the wing 10 firstly bends inward from a direction given by prolonging the ends of the front in a straight line at an edge of the arc shaped front, then bends outward from a direction given by prolonging the ends of the front in a straight line to form an angle about 30 or 40 degrees so that the whole arc shaped portion of the corner protective means 1 looks like a dovetail.
  • a plurality of rib strips 11 are formed to increase the contact area of the wing 10 with concrete structure and thereby strengthen the holding of wing 10 by the concrete.
  • a bent tail 13 is formed at the open end of the wing 10 to reinforce the grip capability of the wing 10.
  • a corner protective means of the present invention having been installed and inserted on a wall corner is illustrated. From this figure, a powerful joining strength provided by the dovetail-shaped structure, the rib strips 11 and the bent tails 13 of the corner protective means 1 can be fully understood.
  • Fig. 2 concrete walls, beams, columns, and their projected corners 14 formed by grouting usually have a surface which needs a first time cement coating to form a layer of roughcast 15.
  • the corner protective means 1 of the invention is positioned over the projected corner 14 in a manner that the wings 10 are buried into the roughcast 15 before the same is dried.
  • the corner protective means 1 shall be firmly inserted thereon.
  • a fine finish 16 formed by a second cement coating shall provide smooth wall surface which is flush with the arc shaped front of the corner protective means 1.

Claims (3)

  1. Moyen protecteur d'angle (1) pour parois, poutres, colonnes, etc., présentant une face frontale de forme arquée et deux ailes (10) formées d'un seul tenant, lesdites ailes (10) s'étendant de deux bords de ladite face frontale arquée, permettant aux ailes (10) de s'étendre dans une direction pratiquement parallèle à une surface de paroi d'un angle sur lequel doit être monté ledit moyen (1), lesdites ailes (10) présentant des saillies et une queue coudée (13) formée à chacune de leurs extrémités libres, qui est en outre orientée vers la surface de paroi,
       caractérisé en ce que :
    - lesdites ailes (10) s'étendent des deux bords de ladite face frontale de forme arquée, des premières parties desdites ailes étant tournées vers l'intérieur par rapport à une direction donnée en étendant tangentiellement, en lignes droites, les extrémités de ladite face frontale,
    - les secondes parties desdites ailes (10) sont tournées vers l'extérieur par rapport à des directions données en étendant les extrémités des parties angulaires tournées vers l'intérieur, pour former des angles d'à peu près 30 à 40 degrés entre la seconde partie de chacune des ailes, dans une direction allant vers la surface de paroi de la face frontale sectorielle, permettant aux ailes (10) de s'étendre dans une direction légèrement inclinée par rapport aux surfaces de paroi le long desquelles est monté ledit moyen protecteur d'angle (1),
    - lesdites ailes (10) présentent une pluralité de bandes de nervure (11),
    - lesdites bandes de nervure (11) sont formées sur les deux côtés de ladite aile (10) de façon à augmenter l'aire de contact sur les deux côtés avec une structure en béton, pour renforcer de ce fait la tenue de ladite aile (10).
  2. Moyen protecteur d'angle (1) selon la revendication 1, caractérisé en ce que lesdites ailes (10) présentent un profil en forme de queue d'aronde.
  3. Moyen protecteur d'angle (1) selon la revendication 1 ou 2, caractérisé par des queues coudées (13) à l'extrémité de chaque aile (10), de manière à renforcer une capacité de serrage de l'aile (10) sur un angle.
