Definitions

  • the present invention relates to a removable step gallery. It is intended in particular to receive spectators at public events.
  • Such a type of grandstand having a solid structure made of tubes joined together.
  • On this structure forming a staircase frame is fixed a floor by fixing means such as nails or bolts.
  • On this floor we just put seats one by one, then we join these seats together and then we fix them on the floor.
  • the platform When the platform is mounted, its rigidity is improved by fixing the cross-pieces in the metal structure.
  • the staircase structure of the grandstand having no steps allows the rubbish to pass through these holes and settle under the grandstand.
  • the object of the present invention is to present a demountable platform which can easily be mounted and then dismantled while overcoming the various drawbacks mentioned above.
  • One of the aims of the present invention is to present a platform having a resistant structure during assembly and disassembly operations.
  • Another object of the present invention is to present a removable step platform which is stable once mounted by the fact that it has structural elements improving its rigidity.
  • the demountable grandstand in particular intended to receive spectators at public events, composed of a metal frame structure, forming a staircase frame, comprising a floor on each step and risers supported in the metal frame, is characterized by the fact that the risers and the boards block each other by embedding the floors between the risers.
  • the invention aims to present a removable step gallery which can be easily installed and which has excellent stability.
  • Figure 1 shows the general appearance of the tribune made according to the present invention.
  • the demountable grandstand 1 is composed of a metal frame structure 2, forming a staircase frame, comprising a floor 3 on each step and risers 4 supported by the metal frame 2.
  • Guardrails 5 and 6 are placed along the lateral sides and on the back of grandstand 1 so as to avoid falls.
  • the floor support frame 7 consists of tubes welded to each other to form a right triangle whose slope is that of the platform.
  • This floor support gantry 7 can be reinforced by welding a tube 15 forming the median of the triangle.
  • brackets 17 On the side 16 of this triangle are welded brackets 17 equidistant from each other. These brackets 17 are connected to each other by support bars 18 which form the steps of a staircase.
  • the brackets 17 and the support bars 18 are positioned in such a way that the support bars 18 are parallel to the long side 19 of the triangle forming the floor support gantry 7.
  • the height gantries 8 consist of tubes welded to each other to form a right triangle whose slope is the same as that of the gantry supports 7.
  • Gantry cranes 7 and 8 are fitted with mounting devices blocking allowing the interlocking of the gantries 7 on the gantries 8 or the gantries 8 between them. It is also possible to fit these gantries 7 and 8 into support legs 9.
  • the support legs 9 are intended to support the entire platform 1. They are composed of a support plate 20 which will be placed on the ground, and of a jack 21 which will allow an adjustment in height so that all the support feet are in contact with the ground whatever its flatness.
  • the different gantries 7 or 8 are interconnected to form the framework of the platform 1, by bracing frames 10. These frames are intended to stiffen the framework of the platform 1. They are composed of tubes welded according to a trapezoidal shape as shown in figure 2. They have interlocking fixing devices allowing their connection with the different gantries 7 and 8.
  • the intermediate risers 12 are made up of metal beams, the cross section of which is C-shaped as shown in FIGS. 2 and 3.
  • the intermediate risers 12 each have an upper part 22 and a lower part 23 interconnected by a core 24.
  • the end 25 of the upper part 22 of the riser 12 is folded outwards at right angles.
  • the front risers 11 are composed of an S-shaped metal beam as shown in Figures 2 and 3 the upper loop 26 of the S has the same shape as the intermediate riser 12.
  • the lower loop 27 of the S bent in the other direction allows it to be fixed by mechanical means to the metal frame 2.
  • the riser is a high riser 13. They are similar to the intermediate risers 12 but they are fixed by mechanical means in the metal frame 2.
  • the various risers 4, that is to say the front risers 11, the intermediate risers 12 and the tall risers 13, are placed between two adjacent floor support gantries 7 as shown in FIGS. 2 and 5.
  • the front risers 11 and high 13 are mechanically fixed by known devices to the different gantries 7.
  • the intermediate risers 12 are maintained between the gantries 7 by means of cleats 28 and 29 as shown in FIG. 3.
  • Each bracket 17 of the gantry 7 comprises at least two upper cleats 28 and two lower cleats 29. These cleats 28 and 29 are integral with the gantry 7.
  • a high riser support 14 fits into the upright 30 of a floor support gantry 7 as shown in Figure 2. This support 14 holds the high riser 13 on the one hand and d on the other hand the rear railings 6 placed along the upper rear side of the platform 1.
  • Railings 5 and 6 are built in a traditional and regulatory manner. They are fixed to the metal frame 2 by traditional assembly means.
  • This metal frame structure 2 forming a staircase whose stepped platform 1 has a floor 3 on each step.
  • This floor 3 consists of boards whose sides are perpendicular to each other.
  • the floorboards 3 are placed on the upper part of a first riser 4 on the one hand and on the lower part of a second riser 4 on the other regardless of the type of riser.
  • the tiered grandstand 1 is installed in a certain order to facilitate assembly. One proceeds by successively mounting the spans forming grandstand 1, starting with the mounting of the right-hand span as shown in FIG. 2. The mounting of the span is carried out stage by stage. The need to assemble the first span in the order which will be described is imposed by the various self-locking systems between gantry supports for the floor 7, gantry gantries 8 and bracing frames 10.
  • the distance between these two gantries depends on the length of the risers 4. In a preferred embodiment, this spacing is about two meters. The lower part of each of these two gantries is in contact with the ground by support legs 9.
  • the front riser 33 is then placed between the two floor support gantries 31 and 32.
  • the lower part 27 of the riser 33 is freely fixed to each of the ends of the gantry 31 and 32 by mechanical assembly means such as bolts for example .
  • the height gantry 34 of the first row is then placed behind the floor support gantry 31.
  • the assembly of these two gantries 31 and 34 is carried out by interlocking.
  • the height gantry 34 is in contact with the ground by means of a support leg 9.
  • a height gantry 35 is placed and fixed behind the floor support gantry 32 of the second row in the same manner as above.
  • the rear parts of the two gantry supports for floors 31 and 32 are joined together by a bracing frame 36, its fixing is also effected by fitting in the gantries 31 and 32.
  • a first rectangle is thus formed, the four sides of which are respectively the gantry 31, the gantry 32, the riser 33, and the frame 36.
  • the base was thus produced, in contact with the ground by the support legs 9, of the first span of the platform 1.
  • the assembly of this first span is completed by fitting the two high riser supports 50 and 51 into the rear parts of the gantries 47 and 48. These riser supports 50 and 51 also allow the assembly of the rear railing 52.
  • the installation of the grandstand 1 is continued by mounting the various risers 4 and the floors 3, starting with the low level of the grandstand 1.
  • the risers 4 and the floors 3 are mutually blocked by embedding the floors 3 between the risers 4.
  • each step which may consist of juxtaposed planks, are completely embedded between the risers 4 and the floor support gantries 7 this so as to protect against impact the four fields of the floor planks 3.
  • the sides of the planks are perpendicular to each other and square the metal frame 2, this ensures good stability and good rigidity at the step stand 1.
  • the intermediate riser 53 is therefore placed between the two floor support gantries 31 and 32. It is supported by the metal frame 2 by means of the cleats 28 and 29 integral with each gantry 31, 32. Then the floor 54 is fitted between the riser 33 and riser 53.
  • FIG. 3 shows us in detail an assembly of riser 4 and of floor 3. It is shown the gantry support of floor 32, the front riser 33, the intermediate riser 53 and the floor 54.
  • the middle part 55 of the riser 33 between the two parts of the S 26 and 27 is supported by two lower lugs 29 integral with the gantries 32 and 31.
  • the riser 33 is assembled to the two gantries 31 and 32 by fixing means 56 blocking it on the cleats 29.
  • the riser 33 is also sup carried by the upper cleats 28 integral with the gantries 31 and 32.
  • the lower part 23 of the riser 53 sits on two other lower lugs 29 integral with the gantries 31 and 32.
  • the upper part 22 of the riser 53 is supported by two other upper lugs 28 integral with the gantries 31 and 32.
  • the floorboards 54 between the risers 33 and 53 are placed on the upper part 22 of the riser 33 on the one hand and on the lower part 23 of the riser 53 on the other hand.
  • the floor 54 and the risers 33 and 53 block each other. Indeed, the lower part 23 of the riser 53 is blocked between the cleat 29 and the end 57 of the floor 54. In addition, the other end 58 of the board 54 blocks the riser 33 at its upper part 25.
  • the blocking by embedding the boards between the risers is favored by maintaining the risers by means of the cleats 28 and 29 secured to the gantries 31 and 32.
  • the floors 3 and the risers 4 are mutually blocked, moreover as shown in FIG. 5, they are immobilized in translation by the floor support gantries 7. In fact, the risers 4, whatever their type, are positioned between two 7 adjacent gantries. The floors 3 recessed between the risers 4 are also recessed between the gantries supporting the floors 7.
  • Figure 4 shows a side view of the embedding of a floor 3 between the intermediate risers 12 and high 13. The blocking is carried out in the same manner as described above but the upper part 22 of the high riser 13 is blocked by traditional mechanical fixing means integral with the upper riser support 14.
  • the laying of the floors is completed by alternately continuing the laying of the intermediate risers 12 then the laying of the floor 3, that is to say laying of the second intermediate riser 12, laying of the second floor 3, laying of the third intermediate riser 12, installation of the third floor 3, and so on until the installation of the last high riser 13 and the last floor 3.
  • the step gallery 1 thus installed has good stability and good rigidity.
  • seat elements are installed on the grandstand. These seat elements 59 or 60 are juxtaposed to each other and are fixed in the metal frame 2.
  • the removable step gallery has locking means so that the seat element is kept in the locked position by the adjacent seat.
  • the various floor support gantries 7 composing the metal frame 2 have several brackets 17 equidistant from each other. At the upper end 61 of these brackets 17, there is fixed, for example, by welding, a support plate 62 of the seat elements 60.
  • This support plate 62 can be constituted by a rectangular metal plate folded in the shape of a V as shown in Figure 3.
  • This support plate 62 comprises at least, on one side of the V, two female elements 63.
  • These female elements 63 are constituted by grooves of specific shape.
  • One of the ends 65 of the oblong opening 64 is terminated by a cylindrical orifice 66 tangent to one of the sides of the opening 64 and whose diameter is much greater than the width of the opening 64.
  • the two grooves 63, made in the support plate, are side by side, on the same part of the V, and their axes are parallel to the longitudinal axis of the support plate 62.
  • the seat element 60 is composed of wooden planks 67 so as to form a bench. At the ends of the wooden boards 67 are fixed, beneath these, two connecting plates 68 of the seat elements 60.
  • connection plate 68 can be constituted by a rectangular metal plate, folded in the shape of a V in the same way as the support plate 62. This connection plate 68 is moreover intended to come into contact on the support plate 62. On one of the sides of the V is fixed on the underside of the plate 68, a male element 69 being able to engage and slide in one of the two female elements 63 of the support plate 62.
  • These male elements are constituted by lugs comprising a head 70 and a body 71.
  • the head 70 of the lug 69 has an outside diameter smaller than that of the orifice 66 of the groove 63, the cylindrical body 71 of the lug 69 has a diameter slightly less than the width of the lumen 64 of the groove 63.
  • Each support plate 62 of the seat elements 60 is produced in such a way as to be able to receive the connection plates 68 of two adjacent seat elements 60 as shown in FIG. 4.
  • the seat element 74 is then fixed to the floor support gantries 7 because the head 70 of the lug 69 cannot pass through the lumen 64 of the groove 63, as shown in FIG. 4.
  • the inclined shape of the support plates 62 and the connecting plate 68 is such that the bench, by its weight and, by the spectators seated on the seat element 60, tends to remain blocked.
  • each connecting plate 68 of the adjacent seat elements 60 covers substantially half the width of the support plate 62 of the seat elements.
  • this second seat element 75 When this second seat element 75 is installed, it becomes impossible to dismantle the first seat element 74 installed. Indeed, the two benches are in contact by their face 72, and it is then impossible to move the first seat element 74 posed to the right. This seat element is held in the locked position by the adjacent seat mounted next to it.
  • step platform 1 between the different brackets 17 of the floor support gantries 7, and this works step by step, seat elements 60 whose assembly is carried out in the order mentioned above.
  • seat elements 60 whose assembly is carried out in the order mentioned above.
  • Each last seat element 60 mounted at the extreme right part of the grandstand is held in the locked position by padlocking means 73, as shown in FIG. 5, so that the latter seat element cannot move to the right.
  • the mounting of all these seat elements 60 contributes to maintaining the parallelism between the different gantries 7 adjacent to the said seat elements 60. As a result, the stability and the rigidity of the step stand 1 are very significantly improved.
  • these seat elements 60 can support plastic shells having the shape of an armchair, this increasing the comfort of the spectators.
  • the platform is dismantled in the reverse order to that just described for its assembly. Its disassembly is easily carried out and therefore the various constituents of this platform are recovered in a good condition allowing its subsequent reinstallation. rement.
