Method and demolition equipment for renovation

The present invention relates to a method of renovation specifically designed to repair an exterior wall of a building, such as a facade, by removing an exterior part such as a shell element, the remainder of the interior structure such as thermal insulation and a sandwich element. / or to allow the inner element to be treated, such as re-coating. The work utilizes a dismantling apparatus comprising a support arrangement mounted on the wall structure and a movable work platform with at least an auxiliary force release arrangement for detaching the outer member from one piece at a time, preferably the outer portion and the inner portion, after removing the traps, by sawing the outside portion with a saw device, such as a diamond circular saw, included in the unloading apparatus.

The method according to the invention is applicable to the repair of facades made of a wide variety of materials. The invention is of particular importance in the repair of prefabricated concrete elements. For this type, usually the so-called. Structures comprising a sandwich assembly are characterized by frostbite or so-called. carbonation.

3 0 Freezing due to freezing of water inside the concrete if the concrete structure does not have sufficient protective porosity. Untreated frostbite can very quickly cause the concrete element to lose strength. The carbonization 35, in turn, results from the transport of carbon dioxide into the reinforced concrete structure, whereby the shrinkage steels inside the concrete are corroded, due to the neutralization of the surrounding concrete. These phenomena have a particularly deleterious aesthetic significance and are also detrimental in strength.

5 Since in practice there have even been cases where individual shell elements have been dropped from the facade of the wall as a result of extensive damage, instead of the above methods in a particularly damaged site, there is a need for very massive action, which means practically removing sandwich panels from outside. .

15 For the removal of the shell element today, for example, the so-called. air bag technology, whereby air bags which, when slowly filled with air, cause the shell element to be detached, are disposed of at appropriate distances between the shell element and the trapping steels which bind it to the inner element. In practice, trap steels are generally located at intervals of 60 to 90 cm, whereby the aforesaid air bag technique is capable of removing the shell element by breaking and dropping one trap at a time.

25

The above procedure is particularly risky from the point of view of occupational safety as it results in all removable mass being dropped from the facade. Depending on the condition of the wall structure to be repaired, there may be situations where a heavily damaged shell element may fall prematurely during the installation of the air bags. For this reason, special attention must be paid to preventive and safe arrangements and working practices, with strict 35 safety rules in place to prevent injury. In addition, the above procedure naturally has the disadvantage of building materials falling down during demolition, whereby lower plantings, vegetation, street coverings and structures below, such as carports, etc. generally suffer significant damage. A further disadvantage of this procedure is, of course, the fact that the shell element detached from each of the wall structures has to be reassembled after lowering, for example by using a bulldozer or the like.

On the other hand, for example in DE 3 710 547, it is known in the prior art to use a wall-supported apparatus for dismantling a wall structure, which comprises a demolition device and receiving parts for assembling material removed from the wall. By way of derogation from the foregoing use, the solution of that publication is mainly intended for disassembling chimneys or the like, wherein the discharge device connected to the chimney support frame breaks the impact energy by utilizing the chimney end pieces while assembling the chimney detachments Such a solution differs in both its purpose and construction from the demolition equipment referred to herein to such an extent that it cannot be used as such for the removal of the shell element of sandwich elements, for example. Also, this solution does not disclose the use of a work platform especially for personnel work, e.g., a working level for a person controlling the use of a demolition equipment, nor an actual rail arrangement for operating a saw belonging to such a solution. Further, in article 3/1996 of Rakennustaito, it is mainly on the principle level that the diamond sawing is performed after cutting the ends 35, after which the pieces of the outer shell to be dismantled are lowered. Again, this solution does not utilize a work platform or a rail arrangement of the above type for the use of a concrete saw.

The purpose of the method of the present invention is to provide a decisive improvement on the above drawbacks and thus to substantially improve the state of the art. To accomplish this objective, the method of the invention is characterized in that such as by moving the first rail in a substantially vertical first rail and then moving the first rail by means of a second rail in a substantially horizontal direction, preferably by moving the trap space at a time, to perform the next vertical sawing, respectively.

The main advantages of the method according to the invention are its simplicity and operational safety, whereby demolition work, which has been found to be very dangerous in practice by the present working methods, can be carried out significantly safer. Furthermore, since, for example, the shell elements are removed and received in a controlled manner preferably by one and the same unloading apparatus, their further processing does not in itself require separate operations, as is the case, for example, when the shell elements are dropped to the ground. The method according to the invention is particularly safe from the point of view of occupational safety as well as being easy to use, since the person who controls its operation can control the operation of the saw integrally from a work platform belonging to the demolition equipment. In addition, the lifting device integral with the unloading apparatus can first ensure that the removable part of the outer part 5 104341 is securely held in place during the removal, after which it can still be easily lowered over or above the work platform by further lifting the work platform takapuolitse.

Advantageous embodiments of the method 10 according to the invention are disclosed in the dependent claims.

The invention also relates to a decommissioning apparatus applying the method, which is further defined in the preamble of the independent claim therein. Mainly characteristic features of the unloading apparatus are set forth in the characterizing part of the corresponding claim.

First of all, the demolition apparatus according to the invention makes it possible to carry out, in a simple and safe manner, the renovation of facades, in particular, for example, sandwich panels. By means of a support arrangement included in the demolition apparatus supported by the wall structure, it is possible firstly to provide a support structure for the work platform moving vertically therewith, and still as an advantageous application for the rail arrangement arranged in connection with the work platform. The rail arrangement further comprises, as a preferred embodiment, a first vertical rail 30 along which the actual saw device is further arranged, for example, to be pressurized and movable. The first rail is further movably coupled to the second rail included in the rail arrangement so that the saw device 35 can perform successive vertical cuts across the entire working width. In a further preferred embodiment, the sawing device is arranged to be pivotable by means of a turning device so that horizontal sawing can also be performed. Thus, the demolition equipment according to the invention eliminates the serious occupational safety risks associated with current working methods, since the person using the demolition equipment does not have to carry out any actual risk operations near the wall structure to be treated, but is permanently protected at the work surface. The support structure, on the other hand, is preferably supported at its upper part, e.g., by means of a tongue-in-cheek wall, and at its lower end, e.g. It is also a major advantage of the invention that the shell elements are both detached and further processed in a fully controlled manner, e.g.

Advantageous applications relating thereto are disclosed in the dependent claims on the unloading apparatus.
