Definitions

  • the invention relates to a device for assembling between them reinforced concrete frame elements, pre-stressed or not, for example beams, posts or the like. It also relates to frames comprising a set of such elements linked together by such assembly devices.
  • framework or frame is meant here a two- or three-dimensional structure.
  • US Pat. No. 2,255,270 discloses an end-to-end assembly sleeve of two wooden beams, in which the assembly is carried out by clamping the ends of the beams.
  • a clamping device could not be used for concrete beams, because of the risks of deterioration of the concrete by the significant clamping forces exerted on the ends of the beams.
  • the subject of the invention is a device for assembling beams, posts or the like in concrete, which is simple and economical to produce and easy to implement.
  • a device comprising a body on which at least two sleeves depend, each intended to receive one end of a profiled element, characterized in that the body has a central cavity communicating through an opening with at least one of the sleeves to allow the introduction of a corresponding profiled element in this cavity, and in that each sheath is formed of two distinct parts suitable for being assembled to one another by clamping and to allow, by clamping between them, the 'assembly of a profiled element on the body.
  • the length of a sheath is chosen such that the forces developed at its junction with the concrete of the element do not risk altering the structure of the latter.
  • the invention provides for taking into account the bending moment, which can be of high value and resulting from the bending moments always present in the vicinity of an assembly junction.
  • the length of the sheath is chosen to avoid crushing of the concrete under the effect of the strong pressures exerted by one face of the sheath on the element.
  • the length of the sheath is sufficient so that in the part of the element subjected to traction due to the existence of the bending moment (s), the forces developed are lower than concrete can withstand tensile stress.
  • the assembly device shown in Figure 1 comprises a hollow body 1 and two sleeves 2 and 3 for clamping the ends (or other parts) of profiles (not shown in this figure) of reinforced concrete, prestressed or not.
  • the sleeves are detachably fixed to the body 1 by means of fixing means such as screws and nuts.
  • the body 1 has two parallel faces 4 and 5 hereinafter called upper and lower faces without these indications implying a limitation as to the position of use of the device. These faces 4 and 5 are interconnected by lateral faces 6 and 7 adjacent to parallel edges of face 4 and by faces 8 and 9, of shorter length (according to their section by a vertical plane) than faces 6 and 7 and connecting, on the one hand, the face 6 to the lower face 5 and, on the other hand, the lateral face 7 to the lower face 5.
  • the body 1 therefore has in vertical section the shape of an irregular hexagon .
  • the body 1 has a plane of symmetry perpendicular to the faces 4 and 5, the face 6 being the symmetry of the face 7 with respect to this plane; similarly, the face 8 is symmetrical with the face 9 with respect to said plane.
  • the faces 6 and 7 have openings 10 and 11 of rectangular shape whose width is half the length.
  • the section of these openings corresponds to that of the profiles to be assembled. They are intended to allow the introduction of the ends of the profiles in the hollow body 1. Their shapes and dimensions are such that a clearance is made between the edges of these openings and the associated profile, when it is present.
  • elongated or oval-shaped holes 12 which, in the example, are four in number and are distributed in a square.
  • the upper face 4 has an opening 13 having the shape of a square with a side equal to the side width of the rectangular opening 10 or 11.
  • the faces 4 and 5 also have ovalized holes 14 distributed in a square of the same side than the side of the square on which the holes 12 are distributed.
  • flanges 15 and 16 are provided which are mutually parallel and perpendicular to the said faces. These flanges are arranged in such a way that the parts of said faces 4 to 9 which are outside the space separating them form rims from which the openings 10 and 11 are excluded but have the ovalized holes 12, 14, etc.
  • Each flange 15, 16 has a central opening, respectively 15a and 16a, with edges parallel to its outer edges. Gussets 17 form reinforcing ribs of the body 1 and are provided outside said space separating the flanges 15 and 16 and at the junction of these flanges with the faces 4, 5, 6 and 7.
  • the body 1 has in its hollow part located between the flanges 15 and 16 and in the vicinity of the middle part of the upper face 4 a stopper 18 with edges substantially parallel to the faces 6 and 7 for the ends of the beams or posts inserted in the hollow part of the body.
  • the sleeve 2 which is intended to be fixed to the body 1 by its face 7, has two parts, or half-sleeves, 20 and 21 identical to each other. It will therefore suffice to describe one of these parts, namely part 20.
  • the latter comprises a section 22 with inverted U section intended to cover the upper face and the upper parts of the lateral faces of a beam or post with section rectangular of width slightly less than that of the base (or central edge) 22a of the profile 22.
  • the expression "upper” or “lower” is used here for convenience of description but not as representing the actual position of the items so designated.
  • the half-sheath 20 has a posterior front edge 23 having in the vicinity of its lateral ends circular holes 24 whose distance between the axes is equal to that between the axes of the holes 12. These holes 12 and 24 are intended to allow passage to bolt rods for fixing the sleeve 2 to the body 1.
  • the half-sheath 20 is bordered, at the bottom, at its four corners, by ears 25, 26, etc.
  • the ear 25 is connected to the rear end of a wing 22b of the profile 23 and to the lower edge of the flange 23.
  • These ears 25, 26 have holes 27, 28 for the passage of clamping screws (not shown ).
  • a rib 29 having a hole 30 which, in the example, is closer to the ear 25 than to the ear 26.
  • the half-sheath 20 also includes anterior frontal ribs 31 and 32.
  • Each of these ribs for example the rib 31, forms a single piece with, on the one hand, the adjacent ear 26 and, on the other hand, the corresponding wing 22b of the profile 22.
  • the upper face of the central wing 22a of the profile 22 has a rectangular opening 33 and the outer face (upper in the figure) of this central wing 22a project, in the vicinity of its front end, ribs 35 and 36 having at their rear part of the edges, respectively 35a and 36a, which form, as will be seen below in relation to FIG. 3, stops for positioning posts or purlins.
  • the rim 23 is, also to ensure such positioning, extended forward by edges 37 and 38 substantially parallel to the wings 22b and 22c, and having anterior edges 37a and 38a.
  • the height of the wings 22b and 22c is, in order to allow tightening, less than the half height of the beam or of the corresponding post.
  • the sleeve 3 also has two identical parts 40 and 41 each of which, for example the half-sleeve 40 has, in the longitudinal direction, the shape of a U-shaped section 42 with a wide base 42a, which has a rectangular opening 43.
  • the wings lateral 42b and 42c of the profile 42 are bordered at their ends and at their free edges by ears 44 having circular holes 45 for the passage of clamping means, for example with screws, tending to bring the half-sleeves 40 and 41 l 'from each other to enclose the end of a beam or post between these half-sleeves.
  • the half-sheath 40 has an upper face 46 comprising circular holes 47 separated by a distance equal to that separating corresponding holes provided on the face 5 of the body 1.
  • the face 46 is provided, between the holes 47, with two ribs 48 and 49 having lower edges, respectively 48a and 49a, forming stops for one end of a beam or post inserted in the sheath 3.
  • Ribs or gussets 50 and 51 (half-sleeve 41, Figure 1) connecting the outer face of a wing of the profile to an edge of a corresponding ear are provided to improve the mechanical rigidity of the half-sleeve.
  • the central wing of the profile is pierced with a hole 52 (which, in FIG. 1, is only visible on the half-sleeve 41) between the ribs projecting from the corresponding upper face.
  • the face 46 is intended to be applied against the lower face 5 of the body 1 and the holes 47 allow passage to fixing means, for example with screws and bolts, of the sleeve 3 to the body 1. These means have a head that can be accommodated in the part of the sheath left free between the end of the beam or post and the face 46.
  • the holes 52 allow the passage to tie rods transversely crossing the sheath in the space separating the ribs 48 and 49 and which is left free because a beam or tight pole between the half-sleeves 40 and 41 cannot enter this space.
  • the distance between the wings 42b and 42c is slightly greater than the width of a beam or a post, the end of which is normally introduced into the sheath 3.
  • the width of these wings 42b, 42c is less than half the width (in transverse direction relative to the width mentioned above) of the beam or post in question, so as to allow the clamping of the end of the beam or post between the two half-sleeves 40 and 41.
  • the angle formed between the faces 4 (or 5) and 6 (or 7) of the body 1 is of the order of 76 °, so that the angle formed by this face 4 or 5 with the general direction of the sheath 2 - so with the beam introduced into this sheath ⁇ is of the order of 14 °, which represents a slope of said value.
  • the body 1 and the sleeves 2 and 3 are preferably made of a metal, for example malleable cast iron.
  • the assembly device is made of a resin concrete, or of a reinforced resin (the resin being for example a polyester), or of concrete in which metal fibers have been incorporated or of concrete reinforced by glass fibers, or in a laminated product with layers of glass fibers and polyester.
  • the body 1 a of the assembly device which is represented in FIG. 2 differs from the body 1 represented in FIG. 1 by the fact that the faces 15b and 16b (corresponding to the faces 15 and 16) have four bosses 55 pierced with holes tapped 56. These tapped holes are distributed in the same way as the ovalized holes provided on other faces of the body 1 a and allow the fixing of sleeves similar to the sleeves 2 and 3.
  • the frame shown in Figures 3 and 4 is formed of reinforced concrete profiles, pre-stressed or not, of rectangular or square section, as well as assembly devices of the type of that shown in Figure 1.
  • the vertical posts are of square section and central posts 60 of greater length are provided, posts 61 of intermediate length and posts 62 of side or lean-to whose length is the shortest.
  • the farm of this frame comprises crossbowmen 63 and 64-the crossbowmen 63 being longer than the crossbowmen 64 ⁇ and purlins 65, 66, of equal lengths between them.
  • the crossbowmen and the. purlins all have the same rectangular section.
  • the bases of the posts 60, 61, 62 are driven into wells 67 provided in a concrete slab 68.
  • the fixing of these base posts is ensured by filling (not shown) of the wells 67 with concrete.
  • the posts have bases at their base drilled with holes allowing them to be fixed to a slab using sealing bolts.
  • the assembly of the pole 62 to the crossbowman 64 is carried out using a device 70 identical to that shown in Figure 1 and arranged in the same way.
  • the end 64a of the crossbowman 64 is introduced inside the body 71 of the assembly device 70, the end face of this crossbowman being in contact with a face of the internal stop of this body (stop 18 on Figure 1).
  • the post 60 (the upper end of which has not been shown) is assembled with two rafters 63 and 63a by means of an assembly device 72 similar to that shown in FIG. 1.
  • the body 73 of the device 72 is identical to the body 1 of the device shown in this FIG. 1, but it is arranged, in the vertical direction, in the opposite direction.
  • the upper part of the pole 60 is fixed, by means of a sheath (not shown) to the face 74 of the device 73 which corresponds to the face 4 of the body 1 (FIG. 1).

  • the ends said crossbowmen 63 and 63a are introduced into the body 73.
  • the assembly of the crossbowmen 63 and 64 to the post 61 is ensured by an assembly device 77 with sheaths 78, 79 and 80, identical, for the sheath 78, with the sheath 3 ( Figure 1) and for the sheaths 79 and 80 at sheath 2 of the device shown in FIG. 1.
  • the sheath 78 clamps the upper end of the pole 61, while the sheaths 79 and 80 clamp the ends of the rafters 64 and 63, respectively.
  • the body 81 of the device 77 has, like the body 1, the shape of an irregular hexagon but, unlike said body 1, its outer faces are parallel in pairs. This body 81 presents an upper face 82 and a lower face 83 which are horizontal.
  • Adjacent to the lower face 83 is a face 84 on which the sheath 79 is fixed.
  • This face 84 forms with the horizontal an angle of approximately 104 ° so that the inclination of the crossbowman 64 relative to the horizontal is equal to 14 ° (25% slope).

  • This sheath 93 encloses the end of a crossbowman 95 forming part of an extension of the hangar.
  • the purlins are fixed to the rest of the framework also by means of the assembly devices already described. However, the ends of these purlins are not clamped between half-sleeves but rest on the upper faces of the half-sleeves enclosing the rafters with which they are fixed. Thus, the ends of the purlins 65 and 66 rest on the upper face of the upper half-sheath 76. As already mentioned above, the lateral positioning of these purlins is ensured by edges 35a, 36a, 37a, 38a (FIG. 1) of these half-sleeves.
  • the cover is formed of asbestos-cement plates 130 covering the purlins.
  • these plates 130 are made of steel and, advantageously, between these steel plates and the purlins there is an insulation material.
  • the longitudinal bracing of the hangar frame can be provided in any manner known per se, for example by providing solid walls or elements arranged in a Saint Andrew's cross.
  • the tie rods 91 as well as the sleeves enclosing the ends of the rafters ensure the bracing along the ramp.
  • the length of the sleeves is chosen such that the pressure developed by the existence of the bending moments does not risk altering the structure of the concrete in contact with the sleeve.
  • the length of the assembly sleeve is chosen such that it does not occur, in the part of the element subjected to traction due to the existence of 'such a bending moment, efforts which would be greater than that which can normally bear prestressed concrete, taking into account that the stress of the concrete born from its cooperation with the reinforcement is weaker at the ends of the element.
  • the clamping length of the sleeves on the profiles is advantageously such that the prestressing is sufficiently established at the outlet of the sleeve in order to make the embedding effective.
  • the clamping length of the sleeves on the end of a prestressed concrete profile forming a crossbowman is of the order of 37 cm.
  • a frame 142 formed of two parallel rectangular frames 143 and 144 arranged so as to form a rectangular parallelepiped.

  • the upper branches 143a and 144a - of these frames are welded, near their ends, to wires 147 and 148 which are perpendicular to them.
  • the length of the frames 143 and 144 is approximately 70 cm, their width approximately 12.5 cm and the distance separating them on the order of 5 cm.
  • the wires 147 and 148 are approximately 10 cm from the respective short sides of the rectangular frames, the small side closest to the end face 150 of the beam 141 is approximately 3 cm from the latter and the width of this face 150 is of the order of 20 cm.
  • the half-sleeves of the assembly device are arranged in such a way that the clamping force is exerted on the lateral faces 151 and 152 of the beam which are parallel to the plane defined by the wires 147 and 148.
  • the lean-to post 62b is fixed to a crossbowman 64b by means of a device for assembly 120 similar to the device 77 for assembling the rafters 63 and 64 to the post 61.
  • the rafters 64b passes entirely through the body 61 of the device 120 and the end 64c of this rafters protrudes outside the hangar while being tightened a sheath 122 fixed to the body 121.
  • This end 64c supports a canopy 123 shown in broken lines in FIG. 5. It will be noted here that it is not necessary to provide, inside the hangar, an additional clamping sheath of the crossbowman 64b.
  • the framework according to the invention is particularly simple to produce.
  • the various elements which compose it are easily storable and have a reduced overall dimensions whereas the frameworks based on reinforced concrete, prestressed or not, previously known, are particularly bulky.
  • this framework can be produced in extremely varied dimensions.
  • only two types of profiles were used, namely square section profiles and rectangular section profiles, which facilitates the assembly of the framework and at the same time reduces the manufacturing costs. From this point of view, it will also be appreciated that the same assembly device can be used in ridge for the connection of two rafters (device 72 in FIG. 3) and for the assembly of a lean-to post with a crossbowman (device 70, fig. 3).
  • the profiles can slide easily in the sleeves and / or the bodies of the assembly devices, before the profiles are locked in the sleeves by tightening with screws and bolts.
  • the mounting of the framework is thus particularly easy and can even be carried out by a person not having any particular skill in the field of the framework.
  • the assembly devices can only be used for roofs having a slope of the order of 25%, it goes without saying that the invention is not limited to this slope value.
  • the lateral faces of the body (not shown), which correspond to faces 6 and 7 (FIG. 1), are pivotally linked to a base (corresponding to face 5) and the upper face is constituted by a plate which has dimensions which are a function of the inclination of the lateral faces.
  • This upper plate is, in this case, fixed to the lateral faces by means of bolts also serving for fixing the sleeves to the lateral faces of the body.
  • the hangar according to the invention is easily removable.
  • its shape can be easily changed; it can in particular be extended, as can be seen with the crossbowman 95 in FIG. 3.
  • the profiles do not have any framework waiting at their ends and that they can be manufactured at using the same molding installation and cut to the desired length by sawing directly on the prefabrication bench.
  • the invention also applies in the case where the profiles do not include metallic reinforcements but are profiles established in prestressed concrete reinforced with metallic fibers or glass fibers.
