FIELD OF TECHNOLOGY

[0003] The proposed invention relates to a protective screen intended for use on the side of a multi-story building during its construction, and, in particular, to a means for maintaining a protective screen relative to the building.

BACKGROUND OF THE INVENTION

[0004] Protective shields are typically used to create a screen or guard located at the edge of ceilings under construction. Until external wall cladding, such as wall panels with windows and cladding panels, is placed on multi-story buildings, the space between the floor and ceiling ceilings (or the space above the floor ceilings) remains open. Therefore, there is a need to provide an external screen for protective purposes and, in particular, to prevent personnel and objects from falling from an unfinished building.

[0005] In the above publications, a system of movable screens moving in a vertical direction, usually up, is described as building structure is up.

[0006] In earlier systems, a number of horizontal support beams are used spaced at intervals along each one or two floors. Horizontal support beams, protruding beyond the perimeter of each overlap, support vertical posts at their extreme ends. From the back of each horizontal support beam to each vertical post, there can be connecting elements, thereby adding rigidity to each post.

[0007] The protective screen is mounted with the possibility of its movement relative to the lattice of the uprights. In the aforementioned patent documents, lifting means such as a winch or jack are used to move the protective shield relative to the uprights. In earlier designs of screen systems, a crane may be used to lift each individual shield.

[0008] The above-described protective shields limit access to the edges of the floors, enclosing them and thereby obstructing the performance of work, such as the subsequent reinforcement of concrete slabs forming the overlap.

[0009] Based on these premises and related problems and difficulties, the proposed invention was developed.

[0010] Some of the objects and advantages of the proposed invention will be apparent from the following description, taken in conjunction with the accompanying drawings, in which, by way of illustration and example, one embodiment of the invention is disclosed.

DETAILED DESCRIPTION OF THE INVENTION

[0036] Turning now to FIG. 1-3, which shows a protective screen device 1 comprising a protective screen 10 supported by a finished slab 20 of a multi-story building and extending vertically to provide a barrier to future ceilings (or slabs shown in broken lines).

[0037] The protective screen 10 is made up of a plurality of panels 11, each panel 11 of the protective screen comprising a frame 12 and a grid-filled panel 13. The protective screen 10 encloses the exterior of the building until the walls with window openings or exterior walls are finally fixed. . This prevents people and objects from falling from the building.

[0038] In addition, the shield 10 extends above the uppermost completed floor to also provide a safe working environment when fastening the formwork to the uppermost floor to create the next floor.

[0039] The protective shield 10 is attached hanging down from the frame means 2 (see FIG. 3) to ensure that the shield 10 is horizontally spaced from the edge of the finished slab 20. With this method, there is access to the edge of the slab 20 forming an overlap.

[0040] The carcass means 2 is supported by a base 3 (see FIG. 3) and comprises at least a pair of vertical carcass elements 15. Each element 15 is supported by a holder 17 (also called a shoe) that is attached to a horizontal support beam 16 (also called finger), which in turn is attached to the plate 20.

[0041] The frame means 2 and with it the protective screen 10 are arranged to move vertically relative to the horizontal support beams 16 and the vertical frame elements 15. In this case, the frame means 2 and the screen 10 can be raised if necessary to perform work on the uppermost overlap to create the next overlap. The means for lifting the frame means 2 and the screen 10 in the case of the proposed invention are the means described in patent document PCT / AU03 / 01112, namely, means containing a jack with a reciprocating movement and fixing means for moving the frame means 2 and the screen 10 up, but not down.

[0042] The horizontal support beams 16 are attached to the plate 20 using a clamp support 21 located on top of each horizontal support beam 16 and attached to the plate 20. A support 22 extends from the clamp support 21 to the top of the vertical frame member 15. This structure rigidly holds the vertical the frame element 15 relative to the plate 20. Additional support beams 16 can be attached to new floors when they are completed, to provide additional support.

[0043] The frame means 2 comprises a plurality of vertically spaced beams 25, each of which is fixed between the vertical bars 14. The frame means 2 further comprises connecting elements 26 and vertical struts 27 to form a rigid frame structure extending between the vertical bars 14. The connecting elements 26 and the vertical struts 27 provide rigidity, contributing to the reliable retention of the protective screen 10 with beams 25.

[0044] Since the horizontal support beams 16 extend only a small distance beyond the edge of the floor of the building (that is, the slab 20), the vertical frame members 15 are also supported close to the edge of the floor of the building. The vertical frame elements 15 can have significant weight, therefore, by placing this weight close to the edge of the plate 20, the cantilever load applied to the horizontal support beams 16 is minimized. In turn, the relatively lighter weight of the screen 10 can then be supported by the frame structure 2 at a distance from plate edges 20.

[0045] The location of the shield 10 at a distance from the edge of the plate 20 allows the support platforms 29 to be positioned between the shield 10 and the plate 20, providing easy access to the outer edge of the plate 20.

[0046] As shown in FIG. 2, the frame means 2 comprises a platform 29 providing a pedestrian walkway extending between the screen panels 11 and the edge of the plate 20. The pedestrian walkway 29 has a first part of wooden boards supported by beams 25, and additional connecting elements 30. To the first part of the pedestrian walk 29 hinged panels 31 are rotated between the open position as shown in FIG. 4 and the closed position as shown in FIG. 2, and also in FIG. 4. The hinged panels 31 are rotated, occupying a horizontal position in which they are supported either by lengthening (not shown) of the connecting elements 30, or by adhering to the corresponding supports located on the plate 20.

[0047] The pedestrian walkway 29 provides a safe approach to the edge of the slab 20, enabling various subsequent molding operations, such as subsequent stress reinforcement, to be performed. Hinged panels 31 allow workers to safely move between levels whose boundaries are defined by platforms 29 and floors of a building.

[0049] A reference to any prior art in the present description is not and should not be construed as confirming or indicating in any form the fact that this prior art forms part of well-known knowledge.

[0050] Those skilled in the art should understand that the use of the proposed invention is not limited to the specific application described. Also, the proposed invention is not limited in its preferred embodiment in relation to the described specific elements and / or properties or depicted herein. It should be understood that the proposed invention is not limited to the disclosed embodiment or options, it allows for the introduction of multiple rearrangements, modifications and substitutions without deviating from the scope of legal protection of the proposed invention, as set forth and defined in the following claims.
