Definitions

• the invention relates to the technical sector of building, and more particularly to the destruction or demolition of structures of particularly complex shape, with risks of collapse of the interior.
• the object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
• One of the technical problems to be solved by the invention is to ensure the deconstruction or demolition of any type of work, with the objective of protecting the interior against falling materials, on the one hand, and to stabilize said structure and to prevent its collapse, on the other hand.
• Another problem to be solved by the invention is to ensure the safety of those working on the work.
• the device comprises at least one inflatable structure having handling means, securing means and inflation means.
• the inflatable structure is made from a fabric, in particular reinforced PVC, suitably cut and assembled to substantially match the internal volume of the part. of building.
• the inflatable structure is adaptable to the shape of the building part to be demolished.
• the handling means are arranged at the top of the structure and are able to cooperate with a hoist.
• the handling means are constituted by at least one ring.
• Another problem to be solved by the invention is to maintain the position of the structure before inflation.
• the securing means are arranged at the base of the structure.
• Lashing means may also be arranged on part of the height of the structure.
• the securing means are constituted by tabs having arrangements adapted to cooperate with fasteners.
• Another problem to be solved by the invention is to avoid deformation of the structure at the time of inflation, for example, and as the demolition of the structure or part of the building concerned.
• bracing means consisting of straps
• FIG. 1 is a perspective view of an embodiment of the inflatable structure according to the invention
• - Figure 2 is a longitudinal sectional view in accordance with Figure 1
• - Figures 3, 4, 5, 6, 7 and 8 are schematic views showing the principle of the method underlying the invention.
• the invention finds a particularly advantageous application for the deconstruction and demolition of parts of buildings or structures, including complex shapes, such as church spiers, domes, arches ...
• the deconstruction method implements an inflatable structure (1) adaptable to the shape of the structure (B).
• This inflatable structure is, for example, made from a properly cut and assembled waterproof canvas to substantially match the internal volume of the structure or part of the building (B).
• a reinforced PVC fabric having a density of about 9 g / m 2 can be used.
• other materials with sufficient sealing and strength characteristics can be used.
• the different parts that constitute the structure are assembled together, in a sealed manner, by any known and appropriate means, such as wiring, thermal welding, high frequency, ultrasound, ...
• the structure (1) after inflation, has a generally very truncal-pyramidal shape.
• the structure (1) has means (2) adapted to cooperate with inflation means, for example a compressed air compressor.
• inflation means for example a compressed air compressor.
• These means (2) may for example be constituted by a valve.
• the upper part of the inflatable structure (1) in particular its top, has handling means (3) constituted by at least one ring or equivalent member adapted to cooperate with a hoist, such as the boom of a crane by example.
• handling means (3) can be arranged at any location of the structure.
• the base (la) of the inflatable structure (1) has securing means (4) constituted, for example, by tabs having eyelets or other arrangements adapted to cooperate with fasteners that has a support member (5). ) on which the whole of the inflatable structure (1) rests. It should be noted that other securing means (4) can be arranged around the walls of the structure (1), over part of the height of the latter.
• the structure (1) has bracing means for example in the form of straps (6) or partitions.
• these bracing means (6) are properly positioned and sized to prevent any deformation of the structure at the time of its introduction for example.
• These bracing means connect, for example, the internal faces facing the structure (1).
• (B) represents the part of the structure or building to be deconstructed, whereas the mark (5) corresponds, as indicated, to a support that is originally present in the work (B) or that is related to the interior of said structure.
• the upper part of the structure Prior to the establishment of the structure (1), the upper part of the structure is demolished (dashed lines shown in FIG. 3) to create an access opening (B1) inside said structure.
• the structure (1) in the deflated state, is hooked by its ring (3) to a lifting and handling device (L) to be arranged inside the structure (B) ( Figure 3).
• the structure (1) still in the deflated state, is then stowed on the support (5) by means of, for example, fastening lugs (4) ( Figure 4). In some cases, it may not be necessary to secure the inflatable structure.
• the structure (5) can then, after being connected to a compressor for example, be inflated to self-adapt to the internal shape of the structure (B) ( Figure 5). At this stage, the structure (1) is hooked or not to the lifting member (L). The inflation pressure is regulated to balance the forces.
• the lifting device is then removed, it is possible to proceed with the deconstruction from top to bottom of the structure (5) perfectly stabilized by preventing its collapse and protected inside against falling materials ( Figures 6 and 7).
• the entire inflatable structure can be made in all shapes, sizes and materials adapted to the internal shape of the structure.
