Definitions

  • the present invention relates to a strip of metal sheet intended to form a connection between two construction elements such as footings or plates, at least one of these elements being of wood, said strip of metal sheet comprising on at least one edge of the anchoring projections provided with teeth intended to be forced into at least one of said construction elements which is made of wood, and comprising between at least some of said anchoring projections at least one member for preventing penetration into the wood.
  • Said anchoring projections in the wood provide slots between them.
  • the object of the present invention is to remedy the drawbacks of the prior art and to propose a sheet metal strip according to the preamble of claim 1, the manufacture of which is easy and inexpensive.
  • the penetration stop member consists of a gouge-shaped tooth projecting outward.
  • the wood which when the sheet metal sinking penetrates into the concavity of the gouge-shaped tooth, abuts on the surface, substantially transverse to the direction of penetration into the wood of the bottom of the gouge, to limit the insertion of the sheet metal strip into the wooden building element.
  • the gouge-shaped tooth has a substantially cylindrical concave wall, connected to the rest of the sheet metal strip by an inflected wall formed by stamping or stamping, said inflected wall defining a surface constituting the bottom of the tooth and substantially orthogonal to the penetration of the tooth in the wood, so as to stop this penetration.
  • the teeth are arranged in the shape of a gouge so that two consecutive teeth have concavities facing opposite directions with respect to the sheet metal strip, which makes it possible to avoid rectilinear initiations of cracks in the wood.
  • the sheet metal strip is folded in a zigzag along fold lines parallel to each other, two portions of strip adjacent to the same fold line forming an obtuse angle.
  • Said sheet metal strip is preferably made of a steel having a protective coating against oxidation.
  • the anchoring projections advantageously include teeth which may have a profile such as that described in patent No. 93 02733.
  • the anchoring of these teeth is improved by the elasticity of the wood which closes on the teeth after their insertion and also by removing the strip of sheet metal substantially stretched by the press during the insertion operation.
  • said sheet metal strip When the sheet metal strip is used for the production of a wood-concrete composite floor, said sheet metal strip preferably comprises on the side and on a edge means intended to ensure the fixing of the sheet metal strip in a concrete plate. .
  • a sheet metal strip according to the invention can also be used to produce a frame element.
  • said sheet metal strip has on its two edges anchoring projections provided with teeth to be forced into the wood and the sheet metal strip comprises between at least certain anchoring projections at least one stop member for penetration into the wood consisting of a gouge-shaped tooth projecting outwards.
  • FIGS 1A and 1B a sheet metal strip 1 according to an exemplary embodiment of the invention.
  • This sheet metal strip 1 has on an edge anchoring projections 4 forming slots and provided with teeth 6 to be forcefully inserted into the wood.
  • the edge region of the strip situated in the interval between two anchoring projections 4, that is to say the base 5 of the slot formed between these anchoring projections 4, is provided with two stop members for penetration into the wood in accordance with the invention in the form of teeth 7 projecting outwards and in the form of a gouge.
  • the sheet metal strip 1 is zigzagly folded along fold lines L and L 'parallel to each other. It thus has undulations as shown in FIG. 1B.
  • the sheet metal strip comprises in each interval separating two consecutive anchoring projections 4 two gouge-shaped teeth 7, formed at equal distance from the same fold line L.
  • the sheet metal strip 1 is also folded at the level of the anchoring projections 4 and more precisely along a fold line L ′ contained in a median plane of symmetry for the anchoring projection concerned.
  • the use of a strip of sheet metal having corrugations has the advantage of increasing the surface of adhesion of the sheet in wood or the building element, and makes it possible to avoid the formation of a rectilinear primer of crack when the sheet penetrates the wood.
  • the use of a sheet having corrugations also has the advantage of facilitating the handling thereof, which can be stored in rolls before its use.
  • the gouge-shaped teeth make it possible, in addition to stopping the penetration of the sheet metal strip into the wood, to improve the resistance of the sheet metal strip in the latter.
  • the adhesion of the gouge-shaped teeth is improved when the two main faces of the latter are coated with a hot-melt adhesive, preferably with a low melting point, so that the simple operation of insertion into the wood creates local heating. sufficient to melt the glue, which on cooling polymerizes and increases the adhesion of the tooth in the wood.
  • the teeth 6 formed on the anchoring projections 4 are advantageously coated with a hot-melt adhesive to increase their adhesion.
  • FIGS. 2A to 2C show a gouge-shaped tooth 7, according to the invention.
  • Each tooth 7 has come into formation with the sheet metal strip by stamping or stamping and has a cylindrical wall 7a connecting to the rest of the sheet metal strip by an inflected wall formed by the union of two wall parts 7b and 7c each having the general shape of a torus portion.
  • the wall part 7b is concave towards the inside of the tooth while the wall part 7c has its concavity situated on the side outside the tooth.
  • the wall portions 7b and 7c define at their junction a surface 7e substantially perpendicular to the direction S of penetration of the tooth 7 in the wood.
  • the wall portions 7b and 7c stiffen the sheet metal in line with the connection of the tooth to the rest of the sheet metal strip and prevent it from bending when it penetrates into the wood.
  • the free end 7d of the tooth is tapered to facilitate insertion into the wood and this end 7d is preferably tapered in the manner of a spoon as shown.
  • the cylindrical wall 7a of the tooth has in cross section a semi-circular shape as shown in FIG. 2C.
  • the teeth 7 are formed on the sheet metal strip so as to be staggered on either side of the sheet metal strip when observed parallel to the fold lines L and L ', as shown in FIG. 1B.
  • FIG. 3 An assembly of two flanges 2a, 2b connected by a sheet metal strip 1 according to the invention, and constituting a frame element.
  • the sheet metal strip 1 is symmetrical with respect to a plane median perpendicular to the fold lines.
  • FIG. 3 shows a small space between the surface of each of the flanges 2a and 2b and the base 5 of the slots, in reality the surface of the flanges 2a and 2b comes to bear on the base 5 of the slots, until 'there is a wood stop against the 7th surface constituting the bottom of the teeth in the shape of a gouge.
  • FIG. 4 An assembly consisting of a concrete floor 3 and a beam 2b connected by a sheet metal strip 1 according to the invention.
  • the sheet metal strip 1 has on a song a fallen edge 9 stiffening the sheet metal and flares 10 allowing the passage and the maintenance of metal reinforcements 11.
  • the sheet metal stampings 8 forming projections participate in the stiffening of the corrugated sheet and ensure its anchoring in the concrete.
  • the opposite edge has anchoring projections 4 and gouge-shaped teeth 7 as described above.
  • the members for preventing penetration into the wood according to the invention make it possible to obtain a well-determined spacing between the two construction elements that the sheet metal strip connects, and therefore to respect construction dimensions with precision.
