Definitions

  • the present invention relates to an anti-spalling edging, in particular, though not exclusively for concrete.
  • Concrete is strong in compression, but weak in tension. Small sections are liable to fail in shear. The result is that edges of concrete slabs are liable to spall, that is the edge is liable to crack away, generally at angle.
  • the problem can be relieved to an extent by a flat steel edging, with may form part of a joint allowing contraction of the slabs on setting and thermal expansion.
  • Flat steel strip can become bent away from the concrete, thus the original problem is not really solved.
  • the steel strip can be reinforced against such bending away by provision of an in-turned edge or return level with the top of the slab. This protects the edge of the slab, but loading, deflections and impact can allow the free edge of the return to lift. This gives rise to another set of problems. In turn the free edge can be turned down and provided with cut-outs for its anchoring in the slab.
  • the object of the present invention is to provide an improved anti-spalling edging
  • an anti-spalling edging comprising:
  • the faces were non-planar, such as being S or W shaped when viewed in plan, preferably the faces are flat and face directly away from a bend connecting the metal strip to the return.
  • the transverse faces predominate compared with fingers of the down-turn extending down between the cut-outs.
  • the fingers are not joined at their distal ends, we prefer to join them at their distal ends to stabilise them during installation and casting of the concrete. Members joining the fingers are important for holding the finger from drawing upwards of the concrete.
  • the metal strip will be of steel galvanised before or after punching of its cut-outs. However, it can also be of stainless steel, mild steel or plastics materials.
  • a pair of anti-spalling edgings will normally be provided as a "joint" between two sections of concrete slab, the two metal strips abutting with the returns extending in opposite directions on laying of the concrete and separating on curing.
  • the joint will normally include dowels extending into the two sections of the slab, for vertical load transfer in use; the dowels may be any type of dowels and indeed are optional.
  • a single anti-spalling edging may be used, particularly at an edge.
  • Figure 1 is cross-sectional view of a joint including two anti-spalling edgings in accordance with the invention.
  • FIG. 1 is a perspective view of the joint.
  • the two anti-spalling edgings are lightly connected together with frangible fixings 5, below the level of the connections.
  • the deep metal strip 21 extends to or close to the base of the slab into which the joint is to be laid. It has a return 28 and up-stand 29 for stiffening it. These features are both optional and may be used separately.
  • the shallow strip 31 also has a return 38, which is angled slightly away from the top return 32.
  • the return 38 has a series of apertures 39. As shown these are of a similar size to the cut-outs 34, but they can be either large or more usually smaller.
  • Beneath the return 38 the deep strip has flat plate dowels 6 welded to it at punched cut-outs 7. On the shallow strip side, the dowels are enclosed in sleeves 8, which allow the dowel to withdraw from the slab portion in which they extend.
  • the dowels are not essential to the working of the invention, and embodiments can be envisaged without dowels.
  • the joint To install the joint, it is set up to form the edge of a slab portion S2, that is with the top of the return at the intended finished height of the slab. It can be temporarily secured by means that form no part of this invention.
  • the slab portion is laid. Once it has cured to a green state, the temporary securement is removed and the portion S3 of the slab on the second side is laid.
  • the concrete forms against the edges 25,35 in a manner that is not prone to spalling.
  • the concrete is able to rise against the underside of the returns, since air can flow out at the edges. Further air escape cut-outs 10 can be provided in the returns 22,32.
  • the slab portions are restrained from vertical movement by the dowels 6, which are known in themselves.

Abstract

L'invention concerne une bordure anti-écaillage comprenant une bande métallique (21, 31) comportant un retour (22, 32) le long d'un bord supérieur et une partie du retour pliée vers le bas (22, 33), espacée de la bande. La partie pliée vers le bas (23, 33) comporte des découpes (24, 34) pour fixer la bordure dans le béton, les découpes (24, 34) étant agencées pour fournir des surfaces contre lesquelles le béton bute lorsqu'il est coulé de niveau avec la surface externe du retour (22, 32). Lors de l'utilisation la bordure anti-écaillage peut être fournie sur un joint (1) entre deux dalles de béton (S2, S3). A cet égard, une paire de bordures anti-écaillage seront fournies, les deux bandes métalliques venant en butée avec les retours (22, 32) s'étendant dans des directions opposées sur la couche du béton. Le joint (1) peut comprendre des goujons (6) s'étendant dans les deux sections du béton pour transfert de la charge verticale lors de l'utilisation.
