Definitions
- the invention relates to a fence and a device for forming a fence connector.
- the steel mesh mats are easy to manufacture and, in principle, also easy to assemble into fencing systems.
- a clamp connection is also known from practice, in which, with the vertical rods being recessed, one engages in a form-fitting manner against the abutting steel mesh mats lying at the same height after they have been deformed by a clamp.
- pliers for pressing a cross connector with ends are U-shaped Cross section for orthogonally aligned individual rods, which together form a cross point, described.
- the pliers levers are connected to each other in a first joint and each have a second joint, on which spreading levers are pivotally mounted on the one hand.
- the spreading levers have jaws which, in the closed state, have an O-shaped opening - corresponding to the circular circumference of one end of the cross connector - and can be pivoted about a joint of the two spreading levers located below the jaws.
- the jaws also gap widely apart on their underside.
- the cross connector can only be held in the jaws in the desired position during the clamping process, because in the middle of the jaw, transversely to the jaw opening, there is a groove that extends over the entire jaw depth and in which the ends of the cross connector, which are not to be formed in the current clamping process, rest. Without this adjustment groove for the specially shaped cross connector, the pliers would be very difficult to handle.
- the invention is therefore based on the problem of proposing a barely perceptible mat connection for fences, which is independent of the grid dimension in which the fence posts are arranged, can be installed as simply as possible and is secured against unintentional loosening.
- Another object of the invention is to propose suitable tools for fence assembly.
- the solution for the fence connection is even more elegant if the steel mesh mats have, for reasons of stability, beads running in the horizontal direction in at least one or more meshes of the steel mesh mat. Then one of these sheet metal clamps can be arranged in the area of the bead, while the second is arranged on the vertically running part of the steel grid mat. This results in a secure connection of adjacent vertical bars in two axes of the steel mesh mat, so that they lie immovably next to each other.
- connection should be made outside the area of a fence post, as there is enough space there to attach a tool for the assembly of the fence connector.
- mat can be easily pre-assembled on a horizontal or vertical bar with the post if the connection between two steel mesh mats is not in front of the post and the distance between the fence posts and their foundations from one another does not have to be specified to the centimeter before the fence assembly.
- Another anti-slip device against the vertical displacement of two steel mesh mats results if the vertical rods to be connected are provided with a plastic coating, because then the coefficient of friction between rod and connector is significantly higher.
- a fence connector that can be used for the fence according to the invention consists of a C-shaped sheet metal part, the dimensions of which are determined essentially by the thickness of the bars to be connected and the sheet thickness, the length of the fence connector should be more than twice the thickness of the vertical bar, so that an accurate angle Forming the fence connector is possible and this is not twisted during the forming.
- stainless steel is preferred as the material for such a fence connector.
- a special lever pliers for reshaping the fence connector.
- Such a long-handled lever pliers with jaws that have a common inner contour that corresponds to the finished, attached fence connector has, as is known per se, three joints in order to achieve a large increase in force with the spreading levers located between the joints.
- the maximum jaw opening corresponds to the width of the C-shaped sheet metal clamp plus manufacturing tolerance.
- each jaw of the lever pliers is mounted several times in the jaw joint arranged directly below the abutment, so that the jaws cannot rotate relative to the joint.
- FIG. 1 shows a fence connection next to a post
- FIG. 2 shows a fence connection in vertical section through a second type of steel mesh mat
- FIG. 3 shows the attachment of a tool for connecting two vertical bars adjacent
- a fence post 10 is shown, on which a steel mesh mat is attached by means of holder 11.
- the steel mesh mat ends in the closed edge mesh 3 with the vertical rod 7.
- a further steel mesh mat consisting of mesh-forming, crosswise arranged, welded together at the crossing points horizontal rods 1, 4, 5 and vertical rods 2, 6, which are in turn closed, is to be attached to this edge mesh
- Have edge stitches 3 The two vertical bars 6, 7 are enclosed and securely held by two fence connectors 8, 9 designed as sheet metal clamps.
- the connector 9 rests immediately below the horizontal bar 1, the connector 8 immediately above the horizontal bar 5, so that a displacement of the two edge meshes 3 in the vertical direction becomes impossible.
- Figure 2 shows in vertical section through a connection point of two steel mesh mats a vertical rod 12 with horizontal rods 13, the vertical rod 12 being bent so that a bead 14 is formed. This bead 14 is used to a
- connector 30 In the area of this bead, while a second connector 31 is arranged in the vertical part of the steel mesh mat outside the bead 14. This results in a two-axis securing of the steel mesh mats against vertical displacement. A horizontal displacement is not possible anyway when the connectors 30, 31 are arranged around the vertical rods 12.
- Figure 3 shows the head of a lever pliers, consisting of the levers 24, 25 which are connected to each other on the lever heads 26, 27 by the joint 23.
- expansion joints 21, 22 expansion levers 19, 20 are pivotally mounted.
- the actual tool jaws 15, 16 are attached to the ends of the spreading levers 19, 20, for example by soldering. These jaws 15, 16 are in turn connected by their overlapping lower ends 28, 29, which form a support for the base of the sheet metal clamp 9, by a jaw joint 18.
- Each jaw 15, 16 is supported at least twice in the jaw joint 18 in order to prevent the jaws from twisting against one another.
- the jaws are drawn in the open state.
- a fence connector 9 was inserted with the position shown, which is held there with slight pre-tensioning of the jaws and around the vertical bars 6, 7 analogously to FIG
