Definitions

  • the present invention relates to the production of concrete surfaces and more particularly to the metal gasket used for this purpose to delimit the slabs.
  • this surface is divided into rectangular or square sections constituting the concrete slabs. This sharing is usually done using metal profiles defining each concrete slab and constituting the joint between the slabs.
  • these seals are provided with means for absorbing variations in the dimensions of the slabs due to thermal variations. These joints must also be able to absorb heavy loads while maintaining the correct level of the slab surface and avoiding any deterioration of the edges of concrete slabs.
  • these joints for concrete slabs are made from sheet steel profiles and more particularly of the type with double profile male and female interlocking such as mortise and tenon which allows the expansion of the slabs and which oppose displacements. vertical when passing heavy loads.
  • a commonly used gasket is made using a double substantially omega-shaped profile whose outer contour of one contours the contour inside each other.
  • the male central portion of the seal must necessarily have a sufficient volume to allow its filling by the concrete during molding.
  • the document WO 99/55968 also discloses a structural joint for concrete slabs comprising on the one hand an L-shaped female profile whose vertical flange extends along the edge of the slab and up to the upper edge thereof and whose double horizontal wing extends inwards from the slab and on the other hand an L-shaped male profile whose vertical wing also extends along the edge of the slab and up to the stop upper and the horizontal flange extends outwardly of the slab so as to engage in the female profile of the adjacent slab.
  • structural joints for concrete slabs comprise on the one hand, an L-shaped female metal profile whose vertical flange extends along the edge of the slab and up to the upper edge of that and on the other hand, an L-shaped male profile whose vertical wing also extends along the edge of the slab and up to the upper edge thereof, extending continuously. along the entire length of the slab.
  • a joint for concrete slabs comprising slab separation means and means for horizontal displacement of the slabs relative to each other, while avoiding a vertical displacement between the edges of adjacent slabs, the joint between two adjacent edges of two adjacent slabs comprising (a) a first profile provided at mid-height and at regular distances a series of tenons, said first section extending along an edge of a first slab; (b) a second profile extending along an edge of a second slab, and (c) a series of mortise-shaped elements.
  • the upper edges of said profiles do not show a fold.
  • the object of the present invention is to overcome the drawbacks mentioned above by simple and effective means which will be described in more detail below.
  • the seal is made from thinner sheet and reinforce the upper edge of the male and female profiles by folding the sheet on itself and compressing this doubled part by means mechanical cold forming to obtain a greater width of the edge with sharp corners and thus obtain an ideal shape of this edge; that is to say to obtain a right angle of the external side of the slab and an edge with a sharp angle on the concrete side.
  • This geometry therefore gives the upper edge of the concrete slab, in contact with the metal edge, an obtuse angle which supports the edge during heavy loads on the edge of the joint.
  • the metal gasket according to the present invention is produced according to the features as described in the appended claims.
  • a joint assembly comprising the male parts 1 and the female parts 2, distributing the surface to be concreted in square or rectangular sections or slabs.
  • FIGS. 2 and 3 show details of the seal in a vertical section AA in the figure 1 .
  • the first male part 1 is made from a steel plate 3 folded on itself, along its upper edge, and cold profiled to form the edge.
  • a series of studs 6 provided at their end with a head or enlargement 7. These studs 6 extend slightly downwards at an angle sufficient to allow effective attachment of the part 1 in the mass of the concrete.
  • this sheet 3 On the lower edge of this sheet 3 are welded at regular distances, a series of pins 5 which extend substantially horizontally on either side of the sheet 3. Below the pins 5 is provided a second vertical sheet 4 which extends downward in substance to the lower part of the slab. The thickness of this sheet 4 may be smaller than that of the sheet 3 since it serves only to separate the two adjacent concrete slabs.
  • the second part 2 of the seal according to the invention is shown in FIG. figure 2 and is composed of a longitudinal plate 8, similar to the sheet 3 of the first part 1.
  • the height of this sheet 8 is limited with respect to the sheet 3 and the lower end is folded on itself in the form of an L directed towards the interior of part 2.
  • a series of studs 12 provided at their end with a head or enlargement 13. These studs 12 extend slightly downwards at an angle sufficient to allow effective attachment of the part 2 in the mass of the concrete.
  • Part 2 also comprises a series of U-shaped mortises 10 whose opening 1 1 is intended to receive the tenons 5 of the male part 1.
  • This opening 1 1 is preferably provided with a conical inlet to facilitate the introduction of the tenon 5.
  • the outer surface of the mortises 10 is provided with attachment grooves for the concrete. Before pouring the concrete, these mortises 10 are pressed on the outer parts of the tenons 5.
  • the mortises 10 are advantageously made of plastic.
  • the two sheets 3 and 8 are juxtaposed and their upper folded surfaces form the sharp edge of the concrete slabs. We can also see the disposition of the series of mortises 10, driven on the respective tenons and studs 12.
  • the figure 5 is a plan view corresponding to the figure 4 on which we can also see the inner part of the pins 5 protruding from the sheet 3 and the series of studs 6 of the first part 1.
  • the concrete is poured until it reaches the upper edges of the sheets 3, 8.
  • the concrete will have flowed on both sides of the separating plate 4 and will have coated the pins 6, 12 and the pieces of the tenons 5 on the one hand of the separation and the mortises 10 on the other hand of separation.
  • a seal is obtained as shown in FIG. figure 6 or one can see the edge of a first slab 14 incorporating the first part 1 of the seal and the edge of a second slab 15 incorporating the second part 2 of the seal according to the invention.
  • the temporary fastening means 9 of the sheets 3 and 6 will break and the slab 15 can then take off completely from the slab 14 and move slightly to the left by moving the tenons 5, the slab 14 inside the mortises 10, the slab 15. This displacement will be much more flexible and without clashes or retained by rusted parts through the mortises 10 of plastic.
  • the vertical loads exerted on the upper surface of the joint according to the invention will be uniformly distributed over the two slab edges; the vertical displacements will be avoided by the pins 5 and the strength of the upper edges of concrete is increased thanks to the obtuse angles ⁇ of the upper corners.
  • the parts of the slabs located between the pieces of the tenons 5 and mortises 10 also allow the recovery of large loads without excessive play at the joint. Indeed, these parts retain the total thickness of the slab thus avoiding as much as possible the cracks and the fracture initiators in the longitudinal direction near the seal.
  • the figure 7 shows in detail the shaping of the upper edge of steel sheets 3 and 8.
  • this edge is folded on itself over the entire length and then profiled cold.
  • a set of three rollers is used, the first of which acts in a horizontal plane H, the second in a vertical plane V (angle of 90 °) and the third in an oblique plane A situated at an acute angle to the roller V and leaving, therefore, an obtuse angle ⁇ relative to the upper surface of the concrete.
  • This angle ⁇ should preferably be obtuse to confer increased strength of the edge of the concrete slab.
  • the figure 8 shows the upper edge of a portion of the joint thus obtained which has sharp corners C and a smooth upper surface S through rolling and cold working.
  • the upper edge of the seal according to the invention is therefore made from steel sheets, 3 to 4 mm thick, whose upper edges are folded on themselves and then cold rolled to obtain a Smooth upper surface with a width of 8 to 12 mm with sharp corners made of hardened steel thanks to the cold deformation which hardens the material and makes it more resistant.
  • the figure 9 shows a corner of concrete slab provided with a portion of the seal according to the invention.
  • the shape thus obtained by the concrete during casting gives it greater resistance F to the wrinkle thanks to its obtuse angle ⁇ at the most critical place.
  • gasket according to the invention Another advantage of the gasket according to the invention is that the quantity of steel required is greatly reduced while providing sharp edges that are reinforced and straight because they can be made from thin steel sheets, one edge of which is folded over. itself and cold rolled which gives it a glossy appearance and increased resistance to the steel thus compressed relative to the edge of a thick sheared sheet with a rough section or a rolled steel plate.
