Description

The utility model relates to construction, namely, to enclosing structures and can be used for fencing plots, houses, as protective noise screens, sunscreens, road noise-absorbing barriers located along roads

A section of the enclosing structure is known (RF patent No. 194355 U1, IPC E04N 17/00, published on 06.12.2019), containing vertically oriented racks with a U-shaped profile installed in pairs at a distance L, in the side walls of which there are cutouts with restrictive ledges, and horizontally oriented lamellas with a figured profile fixed in the racks, while the lamellas can be made:

with an S-shaped cross section;

with a cross section in the form of an inverted Latin letter V,

with a cross section in the form of an open oblique trihedral figure.

The closest in technical essence to the proposed technical solution is the well-known lamella for a one-sidedly visible fence (RF patent No. 194355 U1, MPK E04N 17/00, published on December 6, 2019), consisting of a bent plate, with a seven-sided profile, made with the possibility of placement between the side parts of the channel, and the angles between the first and second, seventh and sixth faces are made in the range from 5° up to 7°, angles between the second and third, third and fourth, sixth and fifth faces - in the range from 134° to 137°, and the angle between the fourth and fifth faces - in the range from 88° to 92°, while the lamel is made with the possibility of fixing on the side parts of the channel by the third and sixth faces.

The disadvantages of the known lamellas is the lack of structural rigidity and, as a result, the possibility of deformation and damage to the edges and edges of the lamellas during assembly of the structure or during external mechanical action (for example, during vandalism).

In addition, the given values of the range of angles when forming the edges limit the possibility of manufacturing types of lamellas with different shaping, which is necessary to create different types of fences at the request of the customer.

The technical result, which consists in increasing rigidity and increased protection against external mechanical damage, as well as expanding the range of lamellas with different sizes and shaping, is achieved in the proposed lamella for the enclosing structure, made of sheet material with a thickness of δ with edges and bends molded at appropriate angles, in that the first face of the lamella is molded at an angle α = 30° ± ε to the second face, where ε= ± 20°, and is made with rolling along the edge, the second face is molded at an angle β = 738° ± ε to the third face, molded at an angle η = 138° ± ε to the fourth face, the fifth face is bent in relation to the fourth face by 180° in the opposite direction to the third face with the formation of a section of increased rigidity with a thickness of σ ≥ 2δ, the sixth face is molded and at an angle θ = 30° ± ε to the third face, and the seventh face is bent relative to the sixth face at an angle λ = 30° ± ε.

The essence of the utility model is illustrated by drawings, where:

figure 1 shows the proposed lamella in cross section;

figure 2 explains the process of assembling a section of the building envelope;

figure 3 shows a section of the building envelope with lamellas in the assembled form.

Figure 4, 5 and 6 shows examples of the implementation of the lamellas with different values of the angles α, β, η, θ, λ, located in a given range of values.

The lamella (figure 1) is made of sheet material with a thickness δ with edges and bends molded at appropriate angles, the first edge 1 of the lamella is molded (bent) at an angle α = 30° ± ε to the second face 2, where ε = ± 20°, and is made with rolling along the edge.

The second face 2 is molded at an angle β = 738° ± ε to the third face 3.

The third face 3 is molded at an angle η = 138° ± ε to the fourth face 4.

The fifth face 5 is bent in relation to the fourth face 4 by 180° in the opposite direction to the third face 3 with the formation of a section of increased rigidity with a thickness σ ≥ 2δ.

With tight pressing of faces 4 and 5 (during molding), σ = 2δ.

If faces 4 and 5 are molded with an air gap, then σ ≥ 2δ.

In both cases, the section with faces 4 and 5 will have increased rigidity.

The sixth face 6 is molded at an angle θ = 30° ± ε to the third face 3.

The seventh face 7 is bent relative to the sixth face 6 at an angle λ = 30° ± ε.

The assembly of the structure is carried out as follows.

Fig. 2 a), b), c) illustrate the step-by-step assembly process.

When assembling the enclosing structure, the fastening of the lamellas 8 is provided by elastic bends of the edges of the lamellas inserted into the lock cutouts 9 and 10 of the vertical profile posts 11, 12 and 13, installed at a given distance from each other (Fig. 3).

The profile rack 11 is made in the form of a channel, two shelves of which have protrusions 14 inclined downwards.

The profile rack 12 is made in the form of a corner, one shelf of which has a protrusion 14 inclined downwards.

The profile rack 13 is made in the form of a channel, one shelf of which has a protrusion 14 inclined downwards, and the second shelf 15 closes the end part of the lamellas 8.

The protrusions 14 of the profile racks are supports for the lamellas and have grooves 9 in the upper parts, into which the upper bends of the lamellas 8 enter, and the cross section of the lamellas follows the contour of the protrusions of the profiles.

The protrusions 14 profile racks in the lower parts are covered by the lower section of the lamellas, formed by faces 4 and 5 and having increased rigidity, which provides protection from external mechanical influences.

Upon completion of the assembly of the structure, the slats 8 are rigidly fixed to the profile racks 11, 12 and 13 (Fig. 3).

In FIG. Figure 4 shows example No. 1 of making a lamella, which has the average values of the angles α, β, η, θ, λ from the possible range of values. This version of the lamella design is the most popular among customers.

In FIG. Figure 5 shows example No. 2 of making a lamella, which has the extreme values of the angles α, β, η, θ, λ from the specified range: α = 10°, β = 168°, η = 168°, θ = 10°, λ = 70°. Lamellas with the specified angles provide the minimum width of the enclosing structure, which is in demand in cases where there are restrictions on the width of the structure.

In FIG. Figure 6 shows example No. 3 of making a lamella, which has other extreme values of angles α, β, η, θ, λ from the specified range: α = 50°, β = 108°, η = 108°, θ = 50°, λ = 50°. Lamellas with the specified angles provide better protection against precipitation with a wider profile of the enclosing structure, if required.

The slats are made of galvanized sheet steel with a thickness of δ = 045-1.50 mm.

Forming edges and bends is performed on specialized equipment.

Compared with known similar products, the proposed lamella design achieves a technical result, which consists in increasing rigidity and protection from external mechanical influences, as well as expanding the range of lamellas with different sizes by expanding the range of geometric parameters during shaping.
