PROTECTIVE DEVICE FOR SKYLIGHTS

OBJECT OF THE INVENTION

The present invention relates to a protection device for skylights, especially for skylights on roofs of industrial buildings.

BACKGROUND OF THE INVENTION

At present, the roofs of industrial buildings usually include skylights to provide natural interior lighting. These skylights constitute weakened parts of the roof itself, and therefore can cause falls while wandering around the roof, for various jobs on it. In addition, it is common for these skylights to materialize through translucent areas of the roofing material itself. For example, it is becoming more and more frequent due to its cost, performance and ease of assembly, to make roofs using sandwich plates, with one or both layers of aluminum, ribbed, and with an internal foam core, on a truss structure. In the skylights, a corrugated sheet of a translucent polymer is placed, in continuity with the sandwich sheets. This makes it difficult for deck operators to appreciate, increasing the chances of an accident.

These drawbacks are solved with the placement of the device of the invention, in said skylights.

DESCRIPTION OF THE INVENTION

The protection device for skylights of the invention serves to protect against falls in roof skylights, especially in skylights of industrial buildings, and according to the invention, it comprises:

-a mesh of dimensions greater than the hole of the skylight, in sufficient measure to overlap the same by the contour, and

-perimeter anchors that comprise support plates in the mesh and in the contour of the hole of the skylight to fix the mesh to it, encompassing it against said contour, and specific fixing screws or rivets of the support plates to the material of the contour of the skylight hole.

In this way it is possible to obtain resistance capable of avoiding falls in the event of an accident.

The assembly is simple, because the mesh can be supplied in rolls, for example 25 meters, and cut to size. Specific cloverleaf screws or rivets can be used for the fixings. The device makes it possible to cover surfaces greater than the width of the mesh by means of overlaps, which can be loose, or be reinforced by specific fixing clips or rings.

Therefore, the device of the invention allows to protect skylights adapting to any size thereof, and also:

- Allows light to pass through the skylight without reducing visibility.

- It can also be used in zones C-5 (very high industrial corrosivity).

- High resistance 600-1200J.

- Easy assembly.

- Low cost of transportation.

- Easy handling and hoisting to deck.

- Low storage space. 300 meters per pallet.

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

The protective device (1) for skylights (2) of the invention, especially usable in skylights of industrial buildings, comprises:

-a mesh (3) of dimensions greater than the hole (20) of the skylight (2), to a sufficient extent to overlap the same contour (21), and

-Some perimeter anchors (4) comprising plates (40, 45) to support the mesh (3) and the contour (21) of the hole (20) of the skylight (2) to fix the mesh to it, and some screws (41) or rivets (42) for fixing the plates (40, 45) supporting the material of the contour (21) of the hole (20) of the skylight (2).

The mesh (3) comprises, in addition to its intermediate wires (39), additional security wires (30) on its longitudinal sides (38) (the longest), to configure, for example, a quadruple perimeter wire that increases security.

For the overlap in the contour of the skylight hole, it is preferred that the mesh (3) has dimensions greater than the hole (20) of the skylight (2) by at least 25 centimeters on each side in its longitudinal direction (35), since a sufficient distance from the anchors to the edge of the hole (20) is achieved so that the cover material make the body sufficient to achieve adequate strength. In this variant, shown in fig 8, resistances of up to 1200J can be achieved. In other variants with minor overlap, as shown in fig 7, resistances of up to 600J can be achieved.

As indicated, the mesh (3) can be one-piece, or comprise at least two portions (31, 32) (see fig 7) with overlapping areas (33), joined together, if the dimension of a one-piece mesh it does not cover the entire surface of the hole (20). In these cases, the overlapping areas (33) of the portions (31, 32) preferably comprise at least ten overlapping spans (34), if there is no connection between wires (30, 39) ensuring that the mesh is not opened by the overlap (variant not shown), may comprise at least five overlapping spans (34) (see fig 7) comprising staples (36) - made of stainless steel preferably tied between wires of the overlapping ends (30, 39) of both portions (31, 32), or may comprise, three overlapping spans (34), comprising tie clips (36) between all the overlapping end wires (30, 39) of both portions. These last two versions provide the consequent material savings without compromising resistance.

Ideally, the mesh (3) is materialized in galvanized electrowelded wire due to its easy availability in different gauges and formats. Furthermore, it can comprise a plasticized coating, not shown, which allows it to withstand corrosive environments on the one hand, and on the other hand said plasticized coating a signaling color (danger, caution).

As for the perimeter anchors (4), they can preferably be of two types:

-simple first support plates (40) (see figs 1 and 2), provided with recesses (43) on their support face against the contour (21) of the hole (20) of the skylight (2), of less depth to the diameter of the wires (30, 39), and simple perforations (44) for the passage of the screws (41) or rivets (42), which thanks to the recesses (43) cover a greater perimeter of the wire and reinforce restraint, and

- a second U-shaped support plates (45) (see figs 5 and 6), whose branches (45a) are separated in magnitude similar to the diameter of the wires (30, 39) of the mesh (3) for the introduction thereof, and which also comprise double perforations (46) (that is, in both branches (45a)) facing each other, for the passage of the screws (41) or rivets (42), which are faster to place, simply inserting the wire or wires between the branches.

The perimeter anchors (4) comprise sealing gaskets (47) (of a similar size in plan as the support plates (40, 45)) made of EPDM for example, and provided or not with holes (48) coinciding with the simple perforations (44) or the double holes (46) for the insertion of the screws or rivets, whose holes can be made at the factory or made during assembly.

Additionally, the possible provision of reinforcements (6) for the perimeter anchors (4) (see figs 3 and 4) has been provided, which comprise two parallel end flanges (60a, 60b) and an oblique intermediate sector (61) that is located joining the end flanges (60a, 60b), the end flanges (60a, 60b) being spaced at a distance equivalent to the height of the ribs (23) of the roofing material that forms the outline (21) of the gap (20) and being one of the flanges (60a) attached to the roofing material in a flat area thereof and the other flange (60b) attached to the central part of a first plate (40), in turn attached to a fret (23) of the cover material. This makes it possible to reinforce the fixation of the anchor in areas of less resistance due to nearby bends, such as ribs (23).

It is preferred that the distance between anchors (4) is about 35 centimeters, since in the tests carried out it has been seen that it is the best compromise between costs and resistance, being able to include anchors (4) at half distance in the starts of the longitudinal direction (35) of the mesh (3), on both sides.

Finally, it should be noted that the screws (41) ideally comprise self-drilling screws, and the rivets (42) comprise cloverleaf rivets.

Having sufficiently described the nature of the invention, as well as the way it is carried out in practice, it should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications in detail as long as they do not alter the fundamental principle.
