Description

The utility model relates to rolling production, in particular to high-quality cold-formed sections of channel type, which are used at construction sites in which such profiles are used, in particular, for fastening suspended ceilings and for facing walls of a building.

Known bent profile [1, Production and use of bent profiles of hire. Handbook Ed. Trishevsky I.S. M .: Metallurgy, 1975, p. 462-469]. It is made of a steel strip billet in the form of a channel.

However, the disadvantage of this profile is its low rigidity.

This disadvantage is eliminated in the bent profile [2, Patent US 8176633, IPC B21D 13/04, priority 08/18/2011, published 05/15/2012], adopted for the first prototype utility model.

The bent profile according to the prototype [2] is made of a steel strip billet in the form of a channel containing corrugation waves in two mutually perpendicular directions. In this case, the waves of corrugations are formed from small depressions and larger protrusions. Such hollows and protrusions are made of a prismatic shape and are interconnected by curved gently sloping surfaces.

The depressions and protrusions are arranged in rows diagonally to the aforementioned mutually perpendicular directions of the corrugation waves.

However, the bent profile - prototype [2] is complex in its design and manufacturing technology due to the presence of three types of corrugation elements - a shallow prismatic hollow, a large prismatic protrusion and a curved gently sloping surface mating them.

In addition, the elongated sections of the curved flat surfaces of the channel in such a bent profile, made for the convenience of orientation of the fastening element screwed into the cavity, have less rigidity than the shorter sections of the protrusions and troughs, which is insufficient for using the bent profile in heavily loaded building structures.

Therefore, the objective of the utility model is to simplify the design, manufacturing technology and increase the rigidity of the bent profile.

The problem for the bent profile is solved in that the bent profile made of a steel strip billet in the form of a channel containing corrugation waves in mutually perpendicular directions, while the corrugations are formed by alternating depressions and protrusions, interconnected by curved surfaces and arranged in rows diagonally to the said mutually perpendicular to the directions of the corrugation waves, has distinctive features: the hollows and protrusions are made spherical.

This embodiment of the depressions and protrusions allows you to get the same size and shape and use the same tool for their formation, which will simplify the design and manufacturing technology of the bent profile, and also shorten, in comparison with the prototype [2], the length of the curved surfaces that connect its depressions and protrusions , which will increase the overall rigidity of the bent profile.

Additional features of the utility model:

- waves of corrugations are formed over the entire surface of the channel;

- waves of corrugations are not formed on the entire surface of the channel;

- mutually perpendicular directions of the corrugations are the transverse and longitudinal directions in relation to the channel length direction;

- mutually perpendicular directions of the corrugations are diagonal directions in relation to the channel length direction;

- the diameter of the conditional sphere inscribed in the cavity does not exceed 5 mm;

- notches are applied on the channel;

- the channel is equipped with longitudinal grooves;

- the ends of the channel are bent at a right or acute angle.

The bent profile 1 (Fig. 1-9) is made of a steel strip billet in the form of a channel of length L, width b and height h. Various sizes of channels can be used (width b × height h):

- 27 × 27 mm for the channel shown in FIG. 1 and 2;

- 50 × 40 mm, 75 × 40 mm and 100 × 40 mm for the channel shown in FIG. 3 and 4,

- 50 × 50 mm, 75 × 50 mm and 100 × 50 mm for the channel shown in FIG. 5 and 6;

- 60 × 27 mm for the channel shown in FIG. 4, 8 and the channel shown in FIG. 9.

Such channels contain waves 2 corrugations 3 (Fig. 2, 4, 6, 8) in mutually perpendicular directions i1 and i2 (Fig. 11, 12). Moreover, in one case (Fig. 11), the mutually perpendicular directions i1 and i2 of waves 2 of corrugation 3 are the transverse and longitudinal directions with respect to the direction iL of the channel length L, and in the other case (Fig. 12) these are diagonal directions with respect to the direction iL lengths L of channel length.

Waves 2 of the corrugations 3 can be formed over the entire surface of the channel of the bent profile 1 (Fig. 1-8) and not over its entire surface (Fig. 9).

Corrugations 3 are formed (Figs. 11 and 12) by alternating spherical depressions 4 and protrusions 5, interconnected by curved surfaces 6 and arranged in rows diagonally in directions i3, i4 to the mutually perpendicular directions i1 and i2 of waves 2 of corrugation 3.

In any place of the channel bent profile 1 (Fig. 1-9) can be applied notch 7 (Fig. 11).

The diameter d of the conditional sphere 8 inscribed in the cavity does not exceed 5 mm for all the channels of the bent profile 1 shown (Figs. 1–9).

The channels of bent profiles 1 can be provided with longitudinal grooves. For example, rectangular grooves 9 (Figs. 4, 6) or acute-angled grooves 10 (Figs. 7-9). The ends of the channels can be bent (Fig. 5-9) with the formation of bends at a right angle 11 (Fig. 5, 6) and bends at an acute angle 12 (Fig. 7-9).

From the bent profile 1 described above, it can be formed (Figs. 16 and 17) using, for example, preliminary orientation of the self-tapping screws 13 (Fig. 14) and their tightening (Fig. 15), the gypsum board fastener 14 (Fig. 16) or the unit fastening siding 15 (Fig. 17).

The drywall fastener 14 (Fig. 16) is formed on the basis of a predominantly horizontally bent profile 1, the channel of which contains, as in FIG. 9, pointed grooves 10 on its sides, with the only difference being that it is provided with bends at a right angle 11. Suspension brackets 16 are mounted on the bent profile 1, which are pre-fixed, for example, to the ceiling 17 using fasteners 18. The suspensions 16 are fastened with a bent profile 1 using self-tapping screws 13, which are screwed into its hollows 4 (Fig. 15).

The attachment site of the siding 15 (Fig. 17) is formed on the basis of a predominantly vertically bent profile 1, which is the same as in Fig. 16. Suspensions 16 are mounted on the bent profile 1, which are pre-fixed, for example, to the wall 19 using fasteners 18. The suspensions 16 are fastened to the bent profile 1 using self-tapping screws 13, which are screwed into its hollows 4 (Fig. 15).
