DE2604136A1 - Reinforced single layer lattice fence component - has enclosing frame of flat iron bar sections - Google Patents

Abstract

The lattice fence component consists of horizontally aligned lengthways rods and vertically aligned cross rods, and provides enhanced rigidity, without incurring the complications resulting from stiffening it by providing rods on both sides. At least on the vertical sides the component is enclosed by a frame made up from flat iron bar sections (4). The open ends of the lengthways and cross rods (2, 3) may be at least partially butt welded to these, and may have holes (5) for rod end fixture. The top horizontally aligned frame section may be a T-shaped unit, with a pronged upward facing stem. The lengthways rods may be wider than the cross rods. The posts may run along the vertical centre line of the components which may be of varying size, and may be attached to the lattice pieces with standard connecting units.

Fence mesh element and fence formed from several such elements

The invention relates to a fence lattice element, consisting of horizontally extending longitudinal bars and vertically extending ones Cross bars, such as a fence made up of several such elements.

There are already known fence lattice elements, the cross bars of which to stiffen the lattice surface on both sides with one Location longitudinal bars are connected. The outer limits of each individual element are determined by the respective formed outer transverse and longitudinal bars. This makes the use of appropriately shaped connecting elements required if adjoining elements are attached to one another to form a fence. The attachment in each case a layer of longitudinal bars on each side of the element requires a relatively high manufacturing cost. aside from that it is undesirable if a lattice fence is easy to climb over from both sides' where for those on both sides of the

Element located longitudinal bars inevitably contribute.

There is therefore the task of designing a fence lattice element of the type mentioned at the outset in such a way that the lattice surface is stiffened without the aforementioned disadvantages.

According to the invention it is provided to solve this problem that the element is bordered at least on the vertical sides by a frame made of flat iron sections. The frame delimiting the element expediently on all four sides of the rectangle gives the inner lattice surface increased rigidity, ie the lattice can neither be easily dented nor bulged because it is practically stretched in a frame. Since the longitudinal bars only run on one side of the element, the opposite side offers the desired protection against climbing over. The flat iron sections delimiting the element on the vertical and horizontal sides allow a mutual connection of adjacent elements in the production of fences in a simple manner by means of screws and nuts. Very important is the further advantage that if posts are used to give the fence a stable stand , the distance and the position of the posts must not be maintained in any particular arrangement with respect to the fence row of elements. This provides a further possibility for stiffening the grid surface of the elements . Because a further increase in the rigidity of the grid surface is achieved if the fence posts run in the middle of each element. As a result, the unsupported grid area is practically halved, and fence posts and adjacent vertically extending flat iron sections alternate as elements for stiffening the grid areas.

Eps ^ en. can easily be done in the usual way by means of Attach the clamps wrapping around the posts or clamps to the grille.

The frame-side ends of the longitudinal and transverse rods can preferably be butted to the perpendicular, . Weld iron sections. A further secure attachment results, however, when the flat iron sections each with openings for receiving and fastening the frame-side Have ends of the longitudinal and transverse rods. The fastening of the grille to the frame is thereby reinforced.

Depending on the type of use of the fence to be formed from the elements, it is either expedient that the frame-side ends of the longitudinal bars and transverse bars received in the openings are at least partially flush with the outside of the flat iron sections, which in any case applies to the vertical sides of the frame, or that the "frame-side ends of the transverse rods received in the openings protrude beyond the ... upper horizontally extending" flat iron section.

FIG. 2 shows a detail of the fence screen element shown in FIG in a perspective view for the purpose of explaining the attachment of the longitudinal and Cross bars of the grid on the surrounding frame;

3 shows a front and a side view of an upper horizontally extending frame section in FIG Training as a T-profile with a jointed upward-pointing bar;

4 shows a view of several to one at the same height running fence of interconnected elements including posts;

5 shows a view of several together to form a fence connected elements that run at different heights;

6 shows a view of several elements placed next to one another as well as one on top of the other, which form a fence are connected to each other.

The grid of the element 1 shown in Fig. 1 consists of a layer of horizontally extending longitudinal bars 2, which connected to a layer of vertically extending cross bars 3, namely at their. Crossing points welded together are. This grid surface is bordered all around by a frame made of flat iron sections 4, each of which are in a vertical position opposite the grid surface of the element 1.

From Fig. 2 it can be seen that the longitudinal bars have a larger cross-section than the transverse bars 3- The free ends the longitudinal and transverse bars 2, 3 are butt-welded to the abutting flat iron sections 4, or they are in openings 5, preferably in bores in the flat iron sections 4, whereby they are either flush with the outer surface of the flat iron sections 4 or protrude from the upper horizontally extending flat iron section 4 as protection against climbing over. The ends are possibly sharpened in the latter case. The free ends are fastened in the openings 5 expedient by welding. Likewise, the flat iron sections 4 are themselves welded to one another by their adjacent ends connected to each other to form a rigid frame.

Fig. 3 illustrates that the upper horizontally extending frame section 4 is also formed from a T-profile can be, whose upwardly facing web 4a is zinc-plated to form an anti-climbing device.

The elements 1 are, as indicated in Fig. 4, by means of screws and nuts not shown in detail connected to a lattice fence, for the corresponding holes in the vertically extending flat iron sections 4 are provided. The posts 6 extend to increase the flexural rigidity of the grid surfaces expediently in the middle of the individual elements 1, the posts 6 in the usual way with the transverse and / or longitudinal bars 3 and 2 are connected.

FIG. 5 shows that the individual elements 1 are also connected to one another in steps in accordance with the course of the terrain can.

What is not shown is the further possibility, above all of framed elements of different sizes different heights, depending on the desired course of the fence, to be connected to one another in a simple manner.

In Figure 6 it is shown that the elements 1 can be arranged both next to and one above the other. This possibility of stable mutual fastening next to one another, which gives a high degree of rigidity and fence elements arranged one on top of the other is especially important for relatively large and high fences such as ball stop fences essential. Of course, the embodiments shown in Figures 4, 5 and 6 are more different Arrangements of the fence elements can be combined or interchanged with one another.
