"» SYSTEM AND METHOD FOR DRAWING BUILDINGS 5

The present invention relates to a system and a method for demolishing a building.

Various techniques are known for demolishing buildings. One of these known techniques is placing 10 explosively chosen positions of explosives, and having the explosives detonated in the expectation and hope that the entire building will collapse.

A disadvantage of this known technique, however, is that when detonating the explosive material in the wide environment, 15 fragments can strike, so that various measures are required to guarantee the safety of the environment. Moreover, the associated dust development is such that much disruption is caused by the demolition of the buildings in question. The dust development also takes a very long time to descend. Another aspect is the noise. A detonation of explosives is accompanied by an enormous noise. For example, various disadvantages of the use of explosives are known.

The present invention has for its object to provide an improved method and an improved system for demolishing buildings, for which purpose the invention prescribes the measures according to claim 1. By simply pushing away at least one load-bearing wall, the structural relationship in the building is broken and it will necessarily collapse. No detonation takes place, which also avoids the danger of flying debris. For this purpose, a coating of the building to be demolished would be required in the prior art, the installation thereof being required. *,> 2 is labor-intensive and time-consuming. Moreover, no noise nuisance takes place and the dust generation, which is considerable with an explosion or detonation, remains very limited in the present system and the present method according to the invention.

The measures according to claim 2 are preferably applied. The anchoring of pulling or pushing means has the advantageous property that it is not necessary to use a wall bearing on its own as an outlet for the pulling or pushing means. This could in fact result in the drawback that the pulling or pushing means push the pulling or pushing element against a load-bearing wall, but not the intended load-bearing wall is pushed away, but the wall against which the pull or push means attempt to deflect. to put.

The measures of claim 3 are preferably taken. For the same reason as the measures defined in claim 2, a post can be used effectively as a barrier for the pulling or pushing means. It is noted in particular that this is a preferred embodiment. For example, there are certain components in buildings that can themselves serve as an outlet, for example an elevator shaft or the like, which is inherently structurally stronger than the usual load-bearing wall in the building to be demolished. By using a post, however, the position of the pulling or pushing means in the building to be demolished can be chosen freely, independently of the position of components of the building that can be used as a barrier.

In an embodiment according to claim 3, the property according to claim 4 can advantageously be applied. In such a way a cross-link is created between the chosen building layer and the building layer below it by means of the upright, with which the resistance required to enable the upright to be deposited for the pushing or pulling means

* A

3 is provided. In such an embodiment it is also possible to apply the measures according to claim 5. Hereby a further strengthening of the upright and a higher usability thereof as an outlet for the pushing or pulling means is provided. In an embodiment according to claim 4 or 5, the invention can also display the features according to claim 6. A concrete reinforcing body around the upright can be considered as encapsulation, but it is important that it provides a higher deposition resistance of the upright for the pulling or pushing means and an improved operation of the pulling or pushing means. pushing means has been achieved.

In an additional or alternative embodiment, the present invention has the features according to claim 7. In such an embodiment, it becomes possible for a long, wide building to collapse completely. Such an elongated building is, for example, a flat with various load-bearing walls. With the measures according to claim 7, it is possible to have the entire building collapsed and not to collapse column after column of the building designed, for example, as a flat, in order to subsequently have to repeatedly apply new or displaced pulling or pushing means, associated pull or push elements.

In yet a supplementary or alternative embodiment according to the present invention use is made of the measures according to claim 8 '. The transverse elements referred to in claim 8 distribute the force exerted on the bearing wall to relieve it with greater certainty. This increases the effectiveness of the invention.

In an embodiment according to claims 7 and 8, the present invention moreover preferably displays the properties according to claim 9. Thus, a plurality of the load-bearing walls in a selected building layer are applied to the forces; · Λ ^ 4 required for the demolition of the building. This can be favorable to subject a large number of the load-bearing walls to the demolition forces, with which the entire building is brought down with greater certainty. The measures according to claim 10 can be applied in such an embodiment. In this way it is achieved that load-bearing walls are subjected to the demolition forces in a succession over time. Hereby the force to be exerted by the pulling or pushing means is lowered relative to the situation in which all of the number of bearing walls must be relieved simultaneously. Moreover, a succession in time is realized in which the load-bearing walls are relieved.

Preferably, the number of pull or push elements, as defined in claim 11, corresponds to the number of transverse elements for load-bearing walls. This is of particular importance with an embodiment of the invention according to claim 12, so that the succession of collapsing columns of the building to be collapsed over time is not interrupted by an interruption of a single pull or push element, but wherein the collapse of a column is accompanied by the release of the associated pulling or pushing element.

A pure sequence of collapsing columns of a building to be demolished is thus ensured.

Furthermore, in an embodiment according to claim 12, the measure according to claim 13 is preferably taken. When a supporting wall located farther away collapses, and the associated column goes along, a corresponding pull or push element comes loose on the side of a non-forced supporting wall. This is advantageous because otherwise a blockage of the demolition mechanism according to the present invention could occur.

By way of example, a possible embodiment of the present invention is shown in the accompanying drawings, in which similar or the same features, properties or components are indicated by the same reference numerals, and in which: Fig. 1 shows a cut-away perspective view of a demolition to be demolished building in which the present invention has been realized; Fig. 2 shows a partly cut-away perspective view of a detail of the embodiment according to the present invention shown in Fig. 1; and Fig. 3 shows a schematic view in more detail of the embodiment of the invention shown in Fig. 1.

Fig. 1 shows a perspective view of a building 1 to be demolished with a method and a system according to the present invention. The building consists of six building layers 2 and the invention 3 has been realized on the fourth building layer, calculated from the ground. This fourth building layer has been chosen because the mass of the building layers above it is sufficient to allow the entire building 1 to collapse when the superimposed building layers, with a sufficient mass, collapse.

The system 3 for realizing the present invention comprises a post 4, which extends through the building layer 2, which is located below the chosen building layer 2 for collapsing the building 1. The post 4 is encapsulated in a concrete block 5 , and extends to the chosen floor level. The upright 4 serves as an outlet for pulling or pushing means, which in the embodiment shown here are designed as a cylinder 6. The cylinder 6 acts on a number of pulling or pushing elements designed as tubes 7. Tubular pull or push elements have the advantage that they can be shaped extremely strongly because of their circular cross-section. With load-bearing walls 8, the tubes 7 are connected to transverse elements 9 via a coupling to be described below. In the embodiment shown here, the transverse elements which are designed as H-profiles are counteracted. and pressed through the bearing walls 8. This means that the constructive relationship in the building 1 to be demolished will be abolished and it will collapse.

The building layer, in which the system 3 according to the present invention is arranged, is chosen in such a way that the upper building layers 2 have such a mass that the collapse thereof is sufficient to cause the lower building layers 2 to collapse as well.

Fig. 2 shows a detail of Fig. 1. It is clearly shown here that the upright 4 protrudes into the chosen building layer 2. The cylinder 6 deposits against the upright 4, which therefore has sufficient resistance as a result of the encapsulation in the lower building layer 2 with a concrete block 5. The H-shaped profile 9 abuts against load-bearing wall 8 to relieve it when the cylinder 6 comes into operation.

Fingers 10 are provided on the H-shaped profile 9, which protrude through the floor 11 of the chosen building layer 1. In this way, the load-bearing wall 12 is also engaged and relieved in the building layer below the chosen building layer when the cylinder 6 is operated. To this end, during preparation for the method and system according to the invention, a number of holes must be made in the floors 11. A number of holes 13 are also provided in the load-bearing wall 8, through which pulling or pushing elements 7 extend. In the embodiment shown here use is made of a number of pulling or pushing elements 7 which are mutually displaced by means of a releasable coupling 14. »3 7 unions. To this end, the pulling or pushing element 7 located closer to the upright 14 is provided with a number of cams 15, into which the further pulling or pushing element 7 fits through the hole 13.

When a supporting wall 8 further away from cylinder 6 collapses or is relieved, the corresponding column of the building to be demolished collapses. The pulling or pushing element 7 further away from the cylinder 6 then comes loose from the cams 15. The relevant column of the building 1 to be demolished collapses and takes along the associated tube 7 and the transverse element 9 shaped as an H-profile.

As shown in Fig. 3, the shape data as H-shaped profiles 9 are transverse elements located at different distances from the associated load-bearing walls. Before the cylinder 6 comes into operation, the H-profile 9 furthest away from the cylinder 6 is close to the associated load-bearing wall 8, which is indicated by arrow C. The H-profile 9 located closer to the cylinder 6 lies at a greater distance from the associated load-bearing wall 8, 20, which is indicated by arrow B.

Finally, the H-shaped profile 9, which is even closer to the cylinder 6, is even further away from the associated load-bearing wall 8, which is indicated by double arrow A. When the cylinder 6 is now put into operation, the cylinder shown in FIG. 3 relieves the load-bearing wall 8 most frequently shown on the right-hand side, as a result of which the column of the building associated with this load-bearing wall 8 collapses. Tube 7 is thereby released from the coupling as a pushing element. The bearing wall 8 shown in the center in Fig. 3 is then next when the H-profile 9 comes to lie against it and the cylinder 6 is still energized. In addition, the column associated with the load-bearing walls 8, 12 falls above and below the floor 11. In the meantime, the cylinder 6 has extended so far that the H-shaped profile 9, which is shown most to the left in Fig. 3, has also come to rest against an associated load-bearing wall 8. The fingers 10 also lie against the lower bearing wall 12. With continuous actuation of the cylinder 6, also the bearing walls 8, 12 shown most to the left in FIG. 3 are relieved, and that part of the building 1 also collapses.

It is noted that it has been shown with reference to Fig. 2 that the coupling formed by cams 15 acts on the side of a load-bearing wall 8 situated opposite the H-shaped profile 9. This has the favorable effect that a collapsing column of the building 1 to be demolished, in the embodiment shown in Fig. 3, carries the associated tube 7 as a pulling or pushing element, without affecting components located closer to the upright 4 or the cylinder 6. of the system, which can act unimpeded, at a later stage, on the associated load-bearing walls 8.

In the above, an explicit description is included, with reference to the accompanying drawings, of a possible embodiment of the present invention, to which, however, the invention is not limited. In the explicitly shown and described embodiment, use is made of a pushing force to relieve load-bearing walls. However, it is possible to use a pulling force. The transverse elements, as shown in Figs. 1, 2 and 3, must therefore be placed on the other side of the associated load-bearing walls. The same applies to the releasable couplings. The advantage of the fingers explicitly shown in Fig. 2 is that load-bearing walls are affected on two different building layers when the cylinder 6, or in general pushing or pulling means, are actuated. However, this is not a requirement of the present invention. As has already been stated above, it is also possible to use structurally more strong components of the building to counteract the pulling or pushing elements, without using a post. Thus, it appears that a person skilled in the art, after taking cognizance of all of the foregoing, can readily imagine various modifications and changes with respect to the embodiments explicitly described and shown above, all of which are within the scope of the definitions defined in the appended claims. 10 screening scope.
