Wave-shapeness is characterized by forming longitudinal recesses. The intercrossing of the cellular structure elements is characterized by its elongated and thickened sections.

Description

The invention relates to building materials and relates to lattice structures used in household plots, agriculture, construction and industry for the construction of decorative and protective fences.

Known fence [1], which includes a metal element made of metal wire in the form of a cellular structure connected to other structural elements. However, a drawback of such a structure is the use of a metal wire, which is susceptible to corrosion.

Also known is the fence [2], selected for the prototype of the first invention, which includes a flexible cellular structural element made of extruded plastic material connected to fasteners.

Moreover, the flexible cellular structural element is a collection of repeating strands formed by vertical and horizontal stripes with the formation of square cells. In addition, paint is applied to the flexible cellular structural member.

The disadvantage of the prototype [2] is the increased complexity of its manufacture because of the need to apply paint to a flexible cellular structural element, as well as the unreliability of the construction of a building structure due to the use of strips of strands, which, due to their small thickness, can be damaged when applied to a relatively large effort to a building structure, for example, as a result of a strong wind.

As a flexible cellular structural element for fencing, it is known to use a plastic cellular structure [3], containing extruded from low-pressure polyethylene and intersecting plates with a smooth surface, arched sides and the same dimensions in width and length forming triangular cells of the same shape and size whose vertices are connected by cylindrical nodal thickenings.

The disadvantage of this structure is the presence of arched sides of the plates, which have extended thin sections and therefore can not withstand large power loads from adverse weather factors, such as strong gusts of wind, or other loads.

In addition, cylindrical nodal thickenings, although they contribute to an increase in the rigidity of the structure, nevertheless impair the ability to twist the product from such a cellular structure into coils for compact storage, which reduces its consumer properties.

A more durable and practical plastic cellular structure for fencing [4], which is taken as a prototype of a utility model. It contains extruded from low-pressure polyethylene and intersecting rectangular plates with a smooth surface and various sizes in width and length, forming polygonal cells of various shapes and sizes, the vertices of which are rounded.

However, due to the presence of rectangular plates with a smaller width, however, although to a lesser extent, the prototype [4] has the above-mentioned first drawback of the analogue [3].

In addition, due to the smoothness of the surface of rectangular plates, such a cellular structure worsens the snow retention of fences in which it is used.

Therefore, the object of the invention is to increase the reliability of the plastic cellular structure for fences and themselves by improving the strength characteristics and by increasing the resistance to the passage of snow through the plastic cellular structure.

The problem for the first invention is solved in that the fence, including a painted flexible cellular structural element made of extruded plastic material, connected to the fastening elements, while the flexible cellular structural element is formed from a set of repeating strands formed by intersecting plates with the formation of cells in the form of polygons with rounded corners, has distinctive features: intersecting plates are made wavy in the horizontal, frontal and profile planes of their projections and are supplemented by rods intersecting with them and between each other in the horizontal and frontal planes of the projection planes, while the flexible cellular structural element was painted in its extruded plastic material due to the filler added to it.

The problem for the second invention is solved in that the flexible cellular structural element for fencing, containing obtained by extrusion from low pressure polyethylene, intersecting plates with different sections in width, forming polygonal cells of various shapes and sizes, the tops of which are rounded, has the following distinguishing features: the plates are made wavy in the horizontal, frontal and profile planes of their projections and are complemented by rods intersecting with them and with each other and, undulating in their horizontal and frontal planes.

The implementation of intersecting fencing plates in a wavy manner, as well as the execution of structural elements of its cellular structure in a wavy shape, is aimed at increasing the tensile strength of the cellular structure and creating an active area of resistance to the movement of snow on its surface.

The wave-like nature of the mentioned elements according to the first and second invention in the indicated planes of their projections enhances these effects, and their wave-like nature and in the additional projection creates additional elements for the development of the active resistance surface of the cellular structure.

The introduction of the cellular structure of the rods according to the second invention further increases its strength.

The implementation according to the first invention of painting a flexible cellular structural element in its extruded plastic material by adding filler to it will eliminate the need to paint a building structure, which will simplify the technology of its creation.

Depending on the size and purpose of the cellular structure, options for the mutual arrangement of its structural elements are possible:

between the adjacent rods are several plates;

between adjacent plates there is one and / or several rods.

The invention is illustrated by illustrations.

In FIG. 1 shows a general view of a plastic cellular structure for fencing with its location on the plane of its horizontal projection. In FIG. 2 and 3 show sections aa and bb of FIG. 1 relative to the frontal plane of projections of the cellular structure. In FIG. 4 shows a section BB of FIG. 1 relative to its profile plane of projections of the cellular structure. In FIG. 5 shows a general view of the enclosure using a plastic mesh structure.

The cellular structure for fencing contains extruded from low-pressure polyethylene by intersecting structural elements - plates 1, 2 and rods 3, 4 with different sections in width, forming polygonal cells 5 of various shapes and sizes, the tops of which are rounded. The honeycomb structure was painted due to the filler added to the low-pressure polyethylene.

Plates 1, 2 and rods 3, 4 are made wavy in the horizontal (Fig. 1) and frontal (Fig. 2, 3) planes of their projections. Plates 1 and 2 are also made wavy and in the profile plane of the projections (Fig. 4). The undulation of the execution is characterized by the formation of longitudinal depressions 6. The mutual intersection of the plates 1 and 2 is characterized by thickened and elongated sections 7. The mutual intersection of the rods 3 and 4 by the thickened and elongated sections 8. The mutual intersection of the rods 3, 4 with the plates 1, 2 by the thickened and elongated sections nine.

In the design of the fence (Fig. 5), the above-described cellular structure is formed as a flexible cellular structural element 10 from a set of repeating strands connected to fasteners, for example, horizontal and vertical metal cross-pieces 11 and 12. The use of other fasteners is also possible (not shown) elements, for example, as in the prototype [2] in the form of wooden racks and braces, or, for example, in the form of special pins, for attaching the cellular structure to the ground and brackets, for screeding its individual canvases between a.

This embodiment of the shapes and arrangement of structural elements 10-12 will allow us to improve consumer qualities in relation to the strength properties of prototypes [2, 4] and analogues [1, 3], to give originality and ease of visual perception of the appearance of this product to be used in a wide range of its application as a fence, for example:

in a private household in the form of a support for climbing plants with vertical gardening on arches, arbors, pergolas, trellises; in the form of props for bushes and berries; in the form of fences, fences, decorative fences; protection of seedlings from rodents, domestic and wild animals; in the form of pens and aviaries for animals and birds;

in agriculture in the form of protection of seedlings from rodents, domestic and wild animals; in the form of protection against wild birds; in the form of pens and aviaries for animals and birds; in the form of fences for retaining snow in the fields;

in construction in the form of an emergency fence, in the form of protective fences from snow drifts on the roads; in the form of structural elements for interior decoration.

In all these cases of universal use of devices according to the utility model, the reliability of structures in which these structures will be used as structural reinforcing elements will improve.
