Definitions

  • the present invention relates generally to mesh panels for use at safety barrier systems used at construction sites as temporary safety fences.
  • the safety barriers are normally mounted like edge protection on flor levels, roofs,
  • Safety barriers are used at for example construction sites as fall protection above ground level, to prevent workers, tools building materials etc. from falling down to the ground or lower floors.
  • safety barrier systems comprise mesh panels, posts, connector members for connecting the mesh panels to the posts and also foot members for anchoring the posts to a substrate as a concrete floor, wooden floor, a roof or a scaffolding etc.
  • the safety barriers are classed according to test standards for testing their strength and to achieve the highest class, known systems are quite heavy, due to coarse dimensions of the parts.
  • known mesh panels these are designed as a Z-like or a C-like fence, with horizontal and vertical wires which are fixed to each other to form a mesh, normally by welding, and which mesh is enclosed by some kind of frame.
  • the main portion of the mesh panel is in a using mode mounted with a vertical extension, and an upper part and a lower part of the mesh panel protrudes either perpendicular or with another angle relative the main portion, such as a section gets a Z-form or a C-form.
  • the mesh is dimensioned with coarse wire dimensions and a certain c/c between the wires to gain high strength and to achieve a high- class mesh panel.
  • Another crucial feature is the weight of an entire mesh panel since they have a length and a height which may be around 2.5 x 1.2 meters.
  • the wire dimensions, the mesh density (number of wires) and the size of the mesh panel drives the weight, which for known low-weight mesh panels in the highest class today is around 20 kg for a mesh panel with dimensions 2.6 x 1.15 meters.
  • WO 2010108832 A1 and EP 17244148 B1 discloses safety barrier systems including posts, mesh panels and fastening devices etc. These solutions focus on the complete system and functions as height adjustments, mounting devices, and of course the safety class, but there is no focus on the mesh panels as such and the combination of weight, safety class and cost.
  • Other known solutions are for example mesh panels and complete systems of aluminum, which indeed have low weight and high safety, but if one aluminium post or mesh panel gets a crack or a buckle, the strength is affected severely. Further, the cost for producing safety barriers of aluminium is high.
  • An object of the present invention is to solve the above-mentioned problems. This is achieved by a mesh panel for safety barrier systems according to claim 1 and a safety barrier system according to claim 15.
  • a mesh panel for a safety barrier system used for securing a working surface comprises a main portion, extending in a main plane defined by a first direction and a second direction.
  • these directions are perpendicular to each other and normally the mesh panel is positioned vertically on a substrate as a floor or the like, and in that case the main plane is a substantially vertical plane and the first and second directions may be the horizontal and the vertical directions.
  • the mesh panel further comprising a top portion, which extends in a top plane defined by the first direction and a third direction, which third direction is different from the second direction such as the top plane is angled relative the main plane by an upper bend.
  • the angle between the top plane and main plane is the angle between the second direction and the third direction.
  • the mesh panel comprising a bottom portion, which extends in a bottom plane defined by the first direction and a fourth direction, which fourth direction preferably is different from the second direction.
  • a section through the mesh panel may look like a Z or a C, where the Z-form is most preferred.
  • the main portion is as understood arranged between the top portion and the bottom portion, and the main portion comprises a plurality of first wires arranged in the first direction and a plurality of second wires arranged in the second direction.
  • the first wires are horizontal wires and the second wires are vertical wires, but other directions may be possible.
  • the first and second wires are fixed to each other at main-interactions such as the first and second wires forming a mesh.
  • the first and second wires are welded together by spot welding.
  • the plurality of first wires comprises an upper wire and a lower wire
  • the plurality of second wires comprises two outer side wires, each arranged at respective outer end of the mesh panel.
  • the outer side wires typically are a left wire and a right wire arranged as outer side frame wires.
  • the top portion comprises at least one first top portion wire arranged in the first direction
  • the bottom portion comprises at least one bottom portion wire arranged in the first direction.
  • the first top portion wire, the bottom portion wire and the outer side wires typically forms an outer frame and the rest of the plurality of first and second wires forming the mesh arranged within the frame.
  • the inventive mesh panel further comprises at least one third wire, wherein at least one of the top portion and the main portion comprises the at least one third wire. If the third wire is arranged in the top portion, it has a top portion wire direction which differs from the first direction and the third direction of the top plane. And if the third wire is arranged in the main portion, it has a main portion wire direction which differs from the first direction and the second direction of the main plane. Further, at least one of the third wire or the plurality of second wires of the main portion, extends past the upper bend and into the adjacent portion. This means that either the third wire or the second (vertical wires) or both, passes over the upper bend and into either the top portion or the main portion depending on where the third wire is positioned.
  • the second (vertical) wires of the main portion extends into the top portion to strengthen the upper bend and utilize the function (strength) of the third wire in the top portion.
  • the third wire is arranged only in the main portion, the second (vertical) wires of the main portion extends into the top portion.
  • the third wire is a part of both the top plane and the main plane. In this case both the third wire and the plurality of second (vertical) wires extends over the upper bend and into adjacent portion (top portion and main portion).
  • wire/wires are to be understood as preferably round wire/wires which normally are used at these applications, but may of course be for example iron bars with different shapes (square, quadratic, pentagonal, hexagonal, octagonal etc.) or the like.
  • the total strength of the mesh panel is improved since either the top portion or the upper the main portion or both, comprises a framework, constituted by“standard wires” (which normally are arranged at such a mesh panels) and the third wire extending between them.
  • the latter is more or less a diagonal cross bar arranged between the wire/wires of the top portion and wire/wires of the main portion as a zig-zag pattern or similar.
  • the bend between them is either enclosed by the strengthening third wire or at least the second (vertical) wires, and the total strength of the mesh panel is greatly improved since the strengthening third wire function is transferred over the upper bend into the main plane in all alternatives.
  • the added diagonal (or any other angles) third wire adds total strength to the mesh panel wherein the both the total number of first and second wires as well as their thickness may be reduced.
  • the weight is greatly reduced and as a comparison, the weight of the inventive mesh panel for the highest class is reduced from 20 kg (prior art) down to 12 kg with maintained strength, which is a huge improvement compared to known mesh panels.
  • the weight reduction is very important when it comes to working environment as the handling the mesh panels often is carried out by hand.
  • the top portion comprises a second top portion wire arranged in the first direction, between the first top portion wire and the upper bend.
  • the at least one third wire extends between the top portion wire and the second top portion wire and is fixed to the first top portion wire and the second top portion wire. Further, the plurality of second wires of the main portion extends past the upper bend and into the top portion.
  • the third wire only is a part of the upper plane, but the strengthening function of the third wire is transferred to the main plane due to that the vertical second wires of the main portion extends over the upper bend and into the top plane.
  • the vertical second wires extend to at least the second top portion wire but may also extend to the first top portion wire.
  • the top portion comprises a second top portion wire arranged in the first direction, between the first top portion wire and the upper bend, but the at least one third wire extends from at least one of the first and second top portion wires to at least one of the plurality of first wires (i.e. horizontal) of the main portion. And the third wire is fixed to these wires which it passes.
  • This embodiment discloses two alternatives. The first alternative is where the third wire is fixed to the first (outermost lying) top portion wire and fixed also to the second top portion wire (near the upper bend) and further also fixed to at least one of the plurality of first (horizontal) wires of the main portion, for example the upper wire or a wire below this, etc.
  • the second alternative is where the third wire is fixed to the second top portion wire but not the first top portion wire, i.e. the third wire is fixed only to the second top portion wire (near the upper bend) and further also fixed to at least one of the plurality of first (horizontal) wires of the main portion, as described above.
  • the at least one third wire is arranged both in the top plane and the main plane AB and passes the upper bend in a strengthening way.
  • the plurality of second (vertical) wires of the main portion may or may not continue into the top portion, it is optionable.
  • the plurality of second wires of the main portion passes the upper bend and continue into the top portion.
  • the at least one third wire extends between the first top portion wire and the upper wire of the main portion and is fixed to the upper wire of the main portion in a point positioned between two adjacent main-interactions of the second wires and the upper wire of the main portion.
  • the third wire is fixed at any point between two interactions, but most preferred is a point near the midpoint of the distance between the interactions.
  • the mesh of the main portion is fixed at the interactions between the first and second wires, and the upper wire of the first wires (normally the upper horizontal wire) is fixed, preferably by spot welding, to the third wire in points between the interactions of the upper wire and the second wires of the main portion, which means improved strength and a stiff corner/bend between the main portion and the top portion.
  • Known mesh panels without the“framework” must have thicker first and second wires as well as more wires arranged closer to each other, to achieve the same strength, which means heavier mesh panels.
  • the at least one third wire is fixed to the first top portion wire in a point which aligns with a respective second wire.
  • the top portion extends, as said above, in a top plane which is angled relative to the main plane.
  • each point for fixed attachment of the third wire to the first top portion wire (which preferably is the outermost wire of the top portion), is arranged at a position which aligns with a respective second wire if seen from the front or the back of the mesh panel.
  • the fixing point of the third wire to the top portion wire aligns with each vertical wire. It is optionable to let the second wires (i.e. vertical wires) extend all the way to the first top portion wire or not.
  • the plurality of second wires (normally the vertical wires) of the main portion extends to the second top portion wire and each of the second wires is fixed to the second top portion wire.
  • the second wires of the main portion extend into the top plane and thus passing the upper bend between the top portion and the main portion, which adds strength to the mesh panel.
  • the second wires may end at the second top portion wire, which enables that the“framework” is open between the diagonal third wires of the top portion and the posts of the safety barrier system may be threaded through the top portion mesh. This enables to standard attachments for attaching the mesh panels to the posts.
  • the plurality of second wires of the main portion extends all the way to the first top portion wire and each of the second wires is fixed to the first top portion wire.
