Mesh panel and a safety barrier system

Abstract

A mesh panel includes a main portion in a main plane defined by first and second directions, a top portion in a top plane defined by the first and a third direction. The main portion includes a mesh formed by a plurality of first wires in the first direction and a plurality of second wires in the second direction. At least one of the top portion and the main portion includes at least one third wire, which, if arranged in the top portion has a top portion direction which differs from the first direction and the third direction of the top plane, and which if arranged in the main portion has a main portion direction which differs from the first direction and the second direction of the main plane.

Description

BACKGROUND AND SUMMARY[0001]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 floor levels, roofs, scaffoldings etc.[0002]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. Normally, 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. Regarding known mesh panels, these are designed as a Z-like or a C-like fence, ...

Benefits of technology

[0013]According to an embodiment, 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. This means that 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. In this embodiment, 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.

[0014]According to yet another embodiment, 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. This option may add strength to the mesh panel a

Problems solved by technology

Other known solutions are for example mesh panels and complete systems of aluminum, which indeed have low weight and high safety, but if one aluminum post or mesh panel gets a crack or a buckle, the strength is affected severely.

Further, the cost for producing safe
