Definitions

  • the invention relates to a removable and earthquake-resistant partition intended to close an opening formed in a vertical wall and in particular in a wall of a room containing radioactive materials.
  • the dimensions of the openings closed by these removable partitions vary according to whether they are intended to allow the passage of a person or of materials. In the first case, these dimensions are generally 1m ⁇ 1.80m. In the case of an opening for the passage of materials, the dimensions of the openings can go up to 5m ⁇ 4m.
  • these demountable partitions are designed so as to be able to withstand the effects of an earthquake, when required by safety analysis.
  • the bricks constituting these demountable partitions are generally in the form of rectangular parallelepipeds with flat faces. Resistance to the horizontal inertia forces perpendicular to the partition which can be produced by an earthquake is obtained by having a supporting frame on either side of the brick stack.
  • this framework is formed by a general sheet metal work or by a grid of metal profiles.
  • Document FR-A-1 232 638 also discloses a partition made of bricks, the shape of which ensures protection against radiation.
  • the bricks are sealed together and crossed by vertical and horizontal metal bars which constitute a framework ensuring resistance to earthquakes.
  • this partition is not removable.
  • the present invention specifically relates to a removable partition and resistant to earthquakes of a new type, not having the drawbacks which have just been mentioned of existing removable partitions.
  • a demountable and earthquake-resistant partition closing off an opening formed in a vertical wall, said partition comprising at least two layers of parallelepiped bricks arranged in superimposed horizontal rows, characterized in that each of said rows comprises at least one central locking brick having a horizontal section in the form of an isosceles trapezium, and bricks having a horizontal section in the form of a parallelogram and arranged symmetrically on either side of the central locking brick, all the central bricks of the same layer being oriented in the same direction, so that each series of bricks behaves like a fictitious funicular arc when the partition is subjected to a horizontal force exerted perpendicular to said partition, in a first direction going from the large base towards the small base of the trapezium formed in horizontal section by the central brick for locking each series, the layers of bricks constituting the two external faces of the partition being formed so that the small bases of the trapezoids formed in horizontal section by the central bricks for locking these layers are placed
  • Such a demountable partition is designed mainly to be placed in a wall of a room containing radioactive materials. However, it can also be used outside the nuclear industry, in all cases where an opening must be able to be made relatively easily in a wall or a vertical wall which must moreover have good resistance to earthquakes. Therefore, if the bricks are preferably made of heavy concrete, having a density higher than that of ordinary concrete, other materials such as ordinary concrete or refractory earth can also be used.
  • the rows of bricks are offset vertically from one layer to another, to avoid leakage by radiation at the joints.
  • the bricks of two adjacent rows of the same layer can also be offset horizontally in a direction parallel to said partition, so as to increase the cohesion of the latter.
  • each of the bricks with a horizontal section in the shape of a parallelogram has a key on one end face and a recess of complementary shape to said key on an opposite end face, each of the bricks with horizontal section in isosceles trapezoid shape having on end faces corresponding to the sides of the trapezoid of recesses of identical shape to that of the recess formed on bricks of horizontal section in the shape of a parallelogram, so that, in each of said rows, each key is received in a recess of the adjacent brick.
  • each row of bricks comprises two series of bricks and an intermediate support brick interposed between said series and having a horizontal section in the form of isosceles trapezium, the intermediate support bricks being oriented in opposite directions with respect to the central locking bricks of the same layer, a vertical retaining profile being fixed to the wall so as to be pressed against the large base of the trapezium formed in section by each of the supporting bricks, this large base of which is placed on an external face of the partition.
  • the support bricks are then identical to the central locking bricks. It is desirable for the partition to include locking pieces capable of simultaneously filling the recesses formed on the end faces of the support bricks and on the adjacent end faces of the bricks of horizontal section in the shape of a parallelogram.
  • a mortar frame is poured between the bricks placed on the periphery of the partition and the opening formed in the wall.
  • the mortar can be replaced by a packing of lead tow between the upper row of bricks and the upper part of the opening formed in the wall.
  • Figure 1 shows a portion of a wall or wall 10, approximately vertical, for example of reinforced concrete, in which is formed an opening 12, of generally rectangular shape.
  • the verticality of the wall 10 is not necessarily rigorous. Indeed, it will be readily understood that the invention also applies to the case of walls having a slight inclination relative to the vertical.
  • the shape of the opening 12 is not necessarily rectangular, even if it is generally openings of this shape that are produced in practice.
  • the opening 12 formed in the wall 10 is closed by a removable partition 14 designed to resist earthquakes.
  • the partition 14 is designed so as to provide protection against the radiation emitted by the radioactive materials which are inside this room.
  • each of these layers is, for example, 20 cm or 30 cm.
  • Each layer is formed by several horizontal rows of bricks 16 and 18 all having in horizontal section the shapes illustrated in FIG. 1.
  • the bricks 16 and 18 are all of parallelepiped shape and have flat and horizontal lower and upper faces, their height being, for example 10 cm.
  • each of the rows comprises a series of bricks formed of a central locking brick 18, having in horizontal section the shape of an isosceles trapezoid, and of bricks 16 having in horizontal section the shape of parallelograms , these bricks 16 being arranged in equal number and in opposite directions, on either side of the central brick 18.
  • the end faces are the adjacent faces of the bricks 16 and 18 of the same row, the end faces 18a of the bricks 18 correspond to the sides of the trapezoids formed in horizontal section by these bricks 18.
  • the end faces of the bricks 16 are designated by the reference 16a.
  • the length of the bricks 16 is, for example 30 cm, the length of the bricks 18 possibly being 15 cm and 25 cm, depending on whether one looks at them from the side of the small base or from the side of the large base of the trapezoid that 'they form in horizontal section.
  • the external faces of the bricks 16 and 18 are designated respectively by the reference 16b for the bricks 16 and by the references 18b and 18′b for the faces of the bricks 18 corresponding to the small base and to the large base of the trapezoid formed in section by these bricks.
  • angles formed between the faces 18a, 18b and 18′b of the central locking bricks 18 are the same as the angles formed between the faces 16a and 16b of the bricks 16.
  • each of the two layers of bricks is made in the same way.
  • the two layers of bricks are arranged in opposite directions, so that the small faces 18b of the central locking bricks 18 are located on the two external faces 14b and 14′b of the partition 14.
  • the bricks 16 and 18 of each row of bricks behave like a fictitious funicular arch.
  • the rows of bricks of one of the layers behave like a fictitious funicular arc when they are subjected to a horizontal load exerted perpendicular to the partition in a first direction (arrow F1 in Figure 1).
  • the rows of bricks of the second layer behave like a fictitious funicular arch when the partition is subjected to a horizontal load exerted perpendicular to the partition in the opposite direction (arrow F2 in FIG. 1).
  • the corresponding fictitious funicular arcs are represented diagrammatically by the hatched parts A1 and A2 in FIG. 1.
  • one of the end faces 16a of each of the bricks 16 preferably has a key 26 constituted by a projecting part extending vertically over the entire height of the brick and having a shape substantially trapezoidal in horizontal section.
  • each of the bricks 16 has recesses 28 which also extend over the entire height of these bricks and have a horizontal trapezoidal section.
  • These recesses 28 are of complementary shape to that of the keys 26, so that the latter come to be housed in the recesses of the adjacent bricks 16 or 18 of the corresponding row, as illustrated in FIG. 1.
  • the keys 26 are received in the recesses 28 with a certain clearance. They therefore do not participate in the transmission of the forces between the bricks when a force is applied according to the arrow F1 or the arrow F2 as is described previously.
  • Figures 2 and 3 illustrate a variant of the embodiment of Figure 1.
  • the rows of bricks 16 and 18 forming the two layers of the partition 14 are vertically offset, so that the planes of horizontal joints between these rows are not aligned by one layer to the other.
  • This vertical offset can be, for example, half a brick height, that is to say about 5 cm if the height of the bricks is about 10 cm.
  • This last characteristic is particularly advantageous in the application of the invention to the production of a removable partition closing off the wall of a room containing radioactive materials. In fact, it provides effective protection against the radiation emitted by these materials.
  • FIG. 4 illustrates another embodiment of the invention comparable to that which has been described previously with reference to FIG. 1.
  • the removable partition 14 is made up of three layers of juxtaposed bricks, each of these layers being formed of overlapping horizontal rows.
  • the two layers forming the outer faces 14b and 14′b of the removable partition 14 are produced in a similar manner to those of the two layers forming the partition described with reference to FIG. 1 (possibly taking into account the variants of the figures 2 and 3).
  • the intermediate layer between the two extreme layers it is produced in a manner analogous to each of the other two layers, and oriented in the same direction as one of them (the right layer in FIG. 4) .
  • the bricks 16, 18 and possibly 16 ′ constituting the partition 14 of FIG. 4 are identical to those which have been described previously.
  • FIG. 5 illustrates another embodiment of the invention in which the opening 12 to be closed by the removable partition 14 according to the invention has a width such that the mechanical resistance of the vertical supports to which the force is transmitted. earthquakes cannot be guaranteed without the addition of an intermediate vertical support.
  • the maximum width between supports is chosen so that the compression stress of the concrete of the fictitious arcs such as A1 and A2 in Figure 1 remains less than a limit opposite. This limiting stress is determined from the compression limit of the concrete.
  • the vertical supports include the keying mortar 20 which is unreinforced, not vibrated and difficult to put in place, an additional safety factor is applied to the compression limit of the concrete.
  • the maximum width thus calculated is, for example, about 4 meters.
  • each row of bricks is formed of two identical series of bricks 16 and 18 placed end to end, so as to close off the entire width of the opening 12.
  • Each of the two series of bricks in the same row is produced in an identical manner to the rows of bricks constituting the partitions which have been described above with reference to Figures 1 to 4.
  • the two series of bricks in the same row are oriented in the same direction and separated by an intermediate support brick 18 'placed between the adjacent end bricks 16 of the two series.
  • These support bricks 18 ′ are bricks having in horizontal section the shape of an isosceles trapezoid. They are preferably identical to bricks 18.
  • the face 18′b of these is located on the external face 14b or 14′b of the partition 14. Consequently, it is necessary to provide supports for transmitting to the wall 10 the forces collected by the bricks 18 ′ in the event of an earthquake.
  • these supports are preferably constituted by vertical profiles 30 having for example an I-shaped section, placed so as to be able to withstand a force exerted perpendicular to the partition respectively in the direction of arrow F1 or the arrow F2.
  • the sections 30 are sealed at the top and bottom of the concrete wall 10 and they are in contact with the faces 18′b of the bricks 18 ′.
  • one or the other of the layers of bricks forming the partition 14 behaves row by row like two fictitious funicular arcs transmitting the force to which they are subjected for half to the vertical internal edges of the opening 12, by means of the keying concrete 20, and for half to the profile 24, by means of the support bricks 18 ′.
  • retaining sections 30 are widely spaced and that their cost is much lower than that of the retaining framework required according to the prior art.
  • the keys formed on the bricks in the embodiments described have only a security role and can if necessary be deleted.
  • the invention is particularly suited to the case of demountable partitions provided for sealing openings formed in the walls of rooms containing radioactive materials, it can also be used outside the nuclear industry.
