Definitions

  • the invention relates to a pre-assembled structural frame. It will find its application in particular in the field of construction and building. It is more particularly intended but not exclusively for the realization of removable hanaars or temporary buildings as main structure or roof.
  • a metal framework in the form of a marquee is installed on the ground, which is covered with a resistant canvas: this arrangement is commonly used by people from the Cirque and the entertainment industry.
  • the purpose of the present invention is to provide a pre-assembled structural frame achievable in plastic or synthetic material or even in wood, in particular but not exclusively intended for the production of building structures, roofs or cupolas overcoming these various drawbacks by facilitating in particular its installation and its assembly.
  • Another object of the present invention is to provide a pre-assembled structural structure that can easily be removed and re-joined minimizing the time required for its implementation and facilitating its transport.
  • Another object of the present invention is to provide a pre-assembled structural frame yes is stable in the position of use and which has a good mechanical strength-material weight ratio.
  • Another object of the present invention is to provide a pre-assembled structural frame which can traditionally be arranged horizontally above a building structure, but which can also authorize the realization of structural construction in the form of a flat or pleated slab, arch, dome or couoole or a combination of various volumes that can be placed on the floor.
  • the pre-assembled structural frame in particular but not exclusively intended for the realization of removable bangars or temporary buildings as main structure or roof, essentially composed of bars, in particular metallic. or in svnthminiaue matter. or wooden or other, is characterized by the fact that it includes movens for fixing and articulation of different bars between them so that the frame is stable in the deployed use position and that it can be folded up when not in use.
  • the structural frame 1, as shown on the different forms, is essentially composed of bars 2. These bars are pre-assembled and disnosed in such a way that they form a framework on which a covering will notably come to rest in order to produce a temporary building or a roof. Depending on the use cases, the bars will be made from metallic materials such as steel. aluminum, or synthetic or wooden or other.
  • This structural frame 1 is modular and consists of a plurality of polyhedra 3 adacents to each other yes are formed by the bars.
  • Figure 1 represents in perspective one of the basic polyhedra 3 forming the framework of frame 1.
  • Each polyhedron 3 is formed by two pyramids. one called upper 4 and the other called lower 5. whose bases 6 are identical and superimposed.
  • the two pyramids 4 and 5 have lateral edges 7, originating respectively from the vertices 8 and 9. constituted by the metal bars 2.
  • these pyramids have a hexagonal base; however other geometric fiqures could be considered.
  • the structural frame 1 comprises means for fixing and articulation of the various bars 2 together so that the frame is stable in the deployed position of use and that it can be folded up when not in use.
  • the various adiacent oolvèdres 3 are connected and articulated with one another by these so-called fixing and articulation means.
  • the length of the side edges 7 will be substantially equal to half the length of the bars 2, this in order to form two pyramids of substantially height identified.
  • Each base 6 will then belong to the same rectilinear horizontal olan.
  • Such a structural frame can then constitute a traditional horizontal framework of roof or bridge. terrace, etc ...
  • Figures 2 and 3 show the arrangement of the different polvédres 3 and show how they are made adjacent. To clarify and facilitate understanding, figure 2 only represents the edges 7 of the upper pyramids 4 of the different oolvédres 3 and figure 3 represents the relative arrangement of the different bases 6 of the pyramids 4 and 5 forming the polyhedra 3.
  • the different vertices of the different polyhedra 3 are alianated on axes 30 to 34 yes are parallel to each other.
  • the different vertices 8 are placed in a staggered manner, thus shifting from one another.
  • Figure 3 shows the fictitious edges of the bases 6 of the different pvramids thus aue the relative position of these bases between them, their respective places being due to the arrangement of the vertices 8 as described above. It should also be noted that when viewed from above, the upper 8 and lower 9 vertices are merged in the same axis.
  • the fixing and articulation means are constituted by a main articulation 10 and 11 respectively placed at each vertex 8 and 9 of said pvramids 4 and 5 and, by an intermediate articulation 12 oleaved at each point of respective contours of the lateral edges 7.
  • the corresponding structural bars 2 will be articulated in the manner of the branches of a pair of scissors.
  • Chaaue beam 2 is common to two pyramids constituting two polvèdres 3 adiacents. Indeed. take the case of the polyhedra repeated 17 and 18 on the fiqure 3.
  • a bar 2 connects the top 8 of the first pyramid forming the upper part of the first oolvédre 17 and the top 9 of the second pyramid then forming the lower part of the second polyhedron 18
  • This bar further comprises at each end a main articulation 10 and 11 as well as an intermediate articulation 12 as aue described above.
  • FIG. 6 shows a detail of the structural frame and in particular a view along arrow 19 of the string 2.
  • Chaaue upper vertex 8 of a polyhedron 3 is connected to a lower vertex 9 of another oolvèdre 3 adiacent par une barre 2 .
  • a plane is thus formed in the water two bars are arranged in a cross and articulated in 12 at their point of competition in the manner of branches of scissors.
  • the figure represents in a first embodiment authorizing a horizontal deployment of the frame the view of a span of the structure shown in Figure 2.
  • This figure shows the different joints 10, 11 and 12 placed on the different beams 2.
  • the different edges 7 are equal to each other.
  • FIG. 5 shows another embodiment in which the intermediate central beams marked 20 are slightly smaller than those forming the adjacent lateral polyhedra.
  • such unitary structures can be juxtaposed in the direction of the length and / or the width by alternating the intermediate central bars 20 with the other slightly larger bars.
  • the frames thus produced can then be in a semi-cylindrical form, in particular in an arch, dome or dome as well as in the form of flat or pleated slabs. Such embodiments are shown in FIG. 7 and in FIG. 8.
  • this structural framework can be placed on the perimeter walls of a building or can also be supported by piles or, depending on the curvature, be fixed to the ground. It then suffices to cover the upper surface 21 of the structural frame 1 with a covering material such as a particularly impermeable canvas to complete the roof of the building.
  • the pre-assembled structural frame 1 is constituted by an assembly of several polyhedra 3 whose edges 7 are formed by bars of different dimensions. ordered and arranged relatively together to form an arch-shaped frame. the said frame then having a lower arch 23 and a lower arch 24.
  • Each of the arches 23 or 24 is formed from bars 2 of two different lengths, the first longer, marked 25. are aus to form the upper arch 23 and the second shorter, marked 26, are they able to form the arch lower 24.
  • the fiaure 9a in particular represents the upper vault 23 while the fiaure 9b represents the lower vault 24 of the frame 1 shown in the fiqure B.
  • This upper arch 23 is braced with the arch lower 24 by crosspieces in the form of scissors as shown in particular in FIG. 5.
  • Each of these scissors is formed by a so-called longer bar and a so-called shorter bar.
  • the upper arch 23 has a radius of curvature defined by R and consists of bars 25 of length defined by L.
  • the radius of curvature R is equal to twice the length of the bars L.
  • the longer bars 25 will have a length of approximately 0.5 R.
  • bars 26 known as shorter will be used whose length defined by 1 will be substantially equal to 3/2 times the length L of the longer bars 25.
  • the pre-assembled structural frame 1 in the form of an arcade which has just been described, has three different dimensions of the edges 7 of the polyhedra 3 constituting it.
  • the intermediate joints 12 of the bars 2 will advantageously be placed so as to divide each bar substantially in a ratio of ⁇ 3 / 2. Then these three dimensions will be respectively 0.536 L. 0.464 L and 0.402 L.
  • this type of frame produced according to the invention, the assembly time of the structure can be reduced very significantly; moreover, its installation is facilitated.
  • this frame can be folded up, requiring only a reduced volume for its storage.
