BR-102020026775-B1 - ASSEMBLY OF WELDED WIRE MESH PANEL AND ONE OR MORE FRAMES, AND WALL OR CEILING REINFORCED BY ONE OR MORE ASSEMBLIES

Abstract

ASSEMBLY OF WELDED WIRE MESH FRAME AND PANEL. The present invention relates to the assembly (10) of a welded wire mesh panel and one or more frames (structures) (16) which is particularly adapted to be tied to a wall or ceiling, where one or more frame points are predetermined. The frames (16) are attached to the welded wire mesh panel, so that said one or more frames surround the predetermined points. The frames (16) facilitate the tying of the welded wire mesh panel to the wall or ceiling, and are strong enough to survive installation.

Description

Description Technical Field [001] The present invention relates to the assembly of a frame (structure) and a welded wire mesh panel, and one or more frames (structures). The invention also relates to a wall or ceiling reinforced by one or more frames of these assemblies. Background of the Technique [002] Patent Application PCT/EP2020/065355 discloses a chain-link steel wire mesh, provided with a pattern of markings indicating the places where the chain-link steel wire mesh should be attached to a wall or ceiling. [003] The advantage of these marks is that they allow for quick and secure mounting of the chain-link steel wire mesh to a wall or ceiling. Screws can be positioned correctly and efficiently, according to a regular pattern provided by the marks. The marks are supplied by a tape attached to the chain-link steel wire mesh. [004] However, given the harsh environment of tunnels and underground mining, these tapes often do not survive the installation of chain-link steel wire mesh on the ceiling or wall. Even worse, due to the friction of the chain-link steel wire mesh against the ceiling or wall, these tapes risk breaking and disappearing before reaching their intended position. Disclosure of the Invention [005] It is a general objective of the invention to avoid the drawbacks of the prior art. [006] It is a particular objective of the invention to provide a marking that is strong and survives installation. [007] According to a first aspect of the invention, an assembly is provided comprising a frame, a welded wire mesh panel, and one or more frames. The welded wire mesh panel is adapted to be tied to a wall or ceiling at one or more predetermined points. One or more frames are attached to the welded wire mesh panel in such a way that these frames encircle the predetermined points. These frames generally form a regular pattern on the welded wire mesh panel. [008] Compared to a flexible chain-link steel wire mesh, the welded wire mesh panel is a rigid panel and, as such, more robust than chain-link steel wire mesh. The frames are also stronger and more robust than the tapes. Furthermore, the frames surround the attachment points to the wall or ceiling. In other words, cable bolts and/or threaded screws are inserted within the frames and do not destroy the frames. It is in this way, as understood herein, that the tapes of the prior art indicate the exact attachment point, so that cable bolts or bars inserted at these points are likely to break and destroy the tapes. The combination of stronger frames in more rigid panels, and the shape of the frames, offers a strong solution and ensures that the marking frames survive installation. [009] In a preferred embodiment, the frames have a color that is visually different from the color of the welded wire mesh panel. The term ‘visually different’ refers to a situation in which a human being with average visual ability can notice the color difference. [0010] The frames are preferably made of plastic, for example of a polymer, more preferably a polymer with a high level of tensile strength, such as polyamide. [0011] Each of the frames is attached to the welded wire mesh panel by at least two fixing points. Four fixing points are preferred since the frames of the welded wire mesh panel may be subjected to twisting during installation. [0012] The frames can be attached to the frame and the welded wire mesh panel by means of glue or after receiving a short local heating burst. Preferably, however, the frames are attached to the welded wire mesh panel by means of an elastic coupling, such as a clamping construction. A clamping construction makes it possible to fix the frames to the welded steel wire mesh panel with simple pressure. [0013] The welded steel wire mesh panel has a first side. This first side is intended to be in contact with, or facing, the wall or ceiling. The wire mesh panel also has a second side. The second side is away from the wall or ceiling. The frames are positioned at a distance from the wall or ceiling in order to secure them as much as possible. [0014] The welded steel wire mesh panel has two sets of parallel steel wires. A first set of parallel steel wires forms the first side, and a second set of parallel steel wires forms the second side. [0015] The frames are preferably coupled to the said first set of parallel steel wires. [0016] The first set of parallel steel wires crosses the second set of parallel steel wires. Two adjacent steel wires from the first set, and two adjacent steel wires from the second set form a mesh, for example a mesh of a rectangular shape. Preferably, each frame surrounds a single mesh. [0017] According to a second aspect of the invention, the assembly according to the first aspect is used to reinforce a wall or a ceiling. [0018] Preferably, fastening means such as cable screws, which secure the mounts to the wall or ceiling, are positioned inside the frames. Brief Description of the Figures in the Drawings [0019] FI
