Definitions

  • the present invention relates to protective walls against blasts of bombs or missiles.
  • this invention is concerned with light-weight protective walls that can be added onto existing structures.
  • Bomb shelters are of course well-known to everyone. These generally comprise steel reinforced concrete structures, usually built underground, having thick walls.
  • Above ground bomb shelters are almost non-existent and are certainly not available in ordinary apartments and offices, particularly on upper floors. Constructing conventional bomb shelters in such places as apartments and offices presents several problems. First of all, the room designated to be a shelter will become significantly smaller, due to the thick concrete reinforced walls that must be erected.
  • the hollow building blocks are "Durisol" blocks composed of a mixture of mineralised wood shaving and concrete. These blocks are light— eight, in the order of about 0.9 tons per cubic meter, as opposed to 2.4 tons per cubic meter for concrete. They also have desirable characteristics with respect to fire resistance and sound absorption, as well as thermal insulation. Walls constructed with Durisol and having reinforced concrete beams are known as such in conventional construction. However, the use of this type of construction for providing blast-proof protective walls is unknown. Furthermore, it was surprisingly found that walls can be constructed with Durisol blocks in accordance with this invention as internal double walls in existing buildings, thus making it possible to provide blast shelters in every apartment on every floor by merely constructing such a wall up against any outside wall in any room.
  • a further advantage of walls made from Durisol or similar blocks is the fact that they provide a decorative surface finish suitable for residential interiors, contrary to walls of poured reinforced concrete or cinder blocks.
  • Durisol blocks Yet another aesthetic benefit from the use of the Durisol blocks is the fact that they are placed directly on top of and adjacent to one another without requiring any binder layer, such as grout or cement.
  • Figure 1 is a frontal view of a protective wall constructed in accordance with this invention.
  • Figures 2a, 2b and 2c are respectively a perspective, top and side view of a Durisol block as known, which is used for constructing a wall according to this invention;
  • Figure 3 is a cross-sectional view of the front of the wall of Figure 1 ;
  • Figure 4 is a cross-sectional view as seen from the top of the wall of Figure 12.
  • FIG. 1 there is shown a wall 1 constructed with Durisol building blocks 2 which have a decorative finish.
  • This wall is constructed within a frame 3 of reinforced concrete all around the wall.
  • the surface finish on the blocks 2 is naturally decorative enough to be suitable for the interior of an apartment, without requiring further finishing.
  • the wall consists of blocks 2 placed on top of one another 4 and next to each other 5 without any spaces left between blocks, thus not requiring any caulking or grouting which would detract from the attractive natural surface of the wall.
  • FIGS. 2a, 2b and 2c illustrate the basic building block suitable for the construction of wall 1.
  • the Durisol blocks 2 are composed of a mixture of mineralised wood shaving and concrete, with high energy absorption capablity and light— eight.
  • These blocks 2 are similar to conventional blocks in dimensions and comprise front walls 10 and side walls 11 and generally have a centre partition wall 12, leaving two hollow sections 13.
  • the side walls 11 and partition 12 have their upper ends grooved 14 to enable steel reinforcing rods to be placed therein.
  • Side walls 11 further comprise a longitudinal extension 15 across about one half of the width of the wall, this extension serving as a tongue for fitting into a corresponding groove 16 when the blocks are placed alongside one another.
  • a reinforced concrete frame bottom ' 20 as shown in Figure 3
  • the blocks 2 are placed thereon in a row adjacent one another.
  • a steel reinforcing rod 21 is then placed horizontally within the trough formed by the adjacent grooves 14 of the blocks 2 extending 22 beyond the terminal blocks 2a and 2b.
  • a second layer of blocks 2 is placed staggered on top of the first layer, so that the partitions 12 are aligned above the walls 11 of the blocks with the hollow sections 13 forming vertical cavities.
  • Steel reinforcing rods 24 are introduced vertically into the cavities 13 and concrete is then poured into these cavities 13 to fill the voids and form a web of vertical and horizontal steel reinforced concrete beams within the blocks.
  • the terminal ends 22 of the steel reinforcing rods are then embedded in concrete which completes the reinforcing frame 3 around the wall 1.
  • the vertical steel reinforcing rods 24 can be inserted into the cavities 13 of the blocks 2 after the first layer of blocks and horizontal steel rods 21 have have been placed in position and tied to the horizontal steel rods 21 where they cross each other 25. Subsequent layers of blocks are then slipped over the vertical steel reinforcing rods 24 and placed in position with the vertical and horizontal steel bars being tied together wherever they cross each other.
  • the core is connected via the reinforcing steel to the reinforced concrete framework of the building Additional strengthening of the protective wall may be accomplished by providing prestressing (post—tension) at the top and bottom and on either side of the wall.
  • This prestress strengthens the membrane (wall) formed by the Durisol blocks and also strengthens its connection to the framework.
  • a wall consisting of conventional building blocks internally reinforced with steel bars;

Abstract

Mur de protection contre les explosions de bombes comprenant des blocs (2) creux, légers et à haute absorption d'énergie, placés en contact direct, les uns au-dessus des autres et les uns à côté des autres. Ces blocs creux présentent des vides verticaux et horizontaux (11, 14) dans lesquels est disposé un treillis de poutres de béton (22, 24) verticales et horizontales, reliées et renforcées par de l'acier, ces renforcements s'étendant au-delà dudit mur dans un cadre de retenue (3). Un procédé est également décrit, selon lequel on protège une pièce construite de manière classique contre les explosions de bombes en construisant un tel mur à côté d'un mur extérieur de pièce.
