Description

The invention relates to the field of construction and improvement of territories in state and individual farms, as well as simple and with sufficient rigidity aesthetically perfect gratings for various purposes.

Known enclosing decorative lattices made by forging with a rectangular cell, see the book "Technique of artistic enamel, embossing and forging", ed. A.V. Flerov et al. M.: Higher School, 1986, p. 166, Fig. 76.

Enclosing decorative lattices, forged as an artwork, are also known, see the book “Technique of Art Enamel, Coinage, and Forging,” ed. A.V. Flerov et al. M .: Higher School, 1986, p. 8, Fig. 3.

Products that are produced by these techniques are performed in limited quantities in small quantities.

Enclosing gratings made by riveting and furnace welding are also known.

Lattices are also made using electric welding, mainly with a rectangular lattice. In contrast to the above, their artistic value is much lower, with the possibility of their manufacture on electric welding machines. See the collection "Industrial and construction equipment" No. 2 (54), 2008, pp. 56-57; pg. 74-75.

Electric welding machines, like manual contact tongs, are used using direct current welding.

The disadvantage of using electric welding for the manufacture of gratings, grids is the low artistic value of the finished product.

The prototype of the invention adopted lattice made using electric welding, mainly with a rectangular cell. See the collection "Industrial and construction equipment" No. 2 (54), 2008, pp. 56-57; pg. 74-75.

Electric welding machines, like manual ones, use contact tongs using direct current welding.

The drawback of manufacturing rectangular lattices and nets is the low artistic value of the finished product.

The technical task of the invention is the manufacture of simple enclosing gratings using the same amount of metal having greater bending strength and with the possibility of a pattern appearing on them at the request of the customer.

The solution to the problem is achieved by arbitrary overlapping of two gratings with a simple pattern when they are combined along the plane of the pattern. The grill can be made using electric welding, pre-harvesting metal rings.

Stiffness analysis of structures made of the same metal by weight, i.e. wires of the same diameter and thickness of the rings, compared to the conditional of non-superimposed rings having a wire thickness in rings with two layers of 0.7 from the conditional, can withstand higher stress during bending.

Figure 1 shows the rings fastened by centers along the vertices of the square. Figure 3 shows the rings of figure 1, fastened by centers along the vertices of the square, and another layer of the same rings superimposed on this layer with an arbitrary displacement of the rings in any direction; figure 4 shows the rings from figure 2, fastened along the vertices of an equilateral triangle, and another layer of the same rings superimposed on this layer with a certain offset of the rings in any direction, and offset by layers from each other at an arbitrary angle along the arc and then rigidly fixed, for example by welding. Figures 5, 6 show the rings from figure 2 and some of the possible versions of the patterns with a moiré effect, temporarily fixed by arbitrary centers, and shifted by layers relative to each other at an arbitrary angle along the arc, and then rigidly fixed, for example by welding.

Stiffness analysis of structures made of the same metal by weight, i.e. wires of the same diameter and thickness of the rings, compared to the conditional of non-superimposed rings having a wire thickness in rings with two layers of 0.7 from the conditional, can withstand higher stress during bending.

For a comparison of the options for enclosing lattices forged with a rectangular cell, see the book “Technique of Art Enamel, Embossing, and Forging,” ed. A.V. Flerov et al. M: Higher School, 1986, p. 166, Fig. 76, and enclosing lattices forged as a work of art, see the book "Technique of Art Enamel, Embossing and Forging", ed. A.V. Flerov et al. M .: Higher school, 1986, p. 8, fig. 3 with figures 4, 5, 6 and according to the present description, shows the appearance of a large number of ornaments that can participate in the installation of decorative fences, with filling window openings and manufacturing small forms of gratings, including radiators for mobile vehicles and heating appliances.

The use of decorative gratings in the construction and improvement of territories in state and individual farms, simple and with sufficient stiffness of gratings for various purposes makes it possible to appear on them at the request of the customer, with the same diameters of the rings made it makes it possible to save metal due to the smaller diameter of the wire for workpieces while maintaining strength and increase the rigidity of the product.
