Description

Technical field

The utility model relates to the construction industry, in particular to long profile products made of metal.

State of the art

A device is known - a T-shaped profile specified in the source https://www.techno-fence.ru/balki-relsi-dlya-vorot/tproduct/187858010-607295079996-t-profil-dlya-sborki-vorot-i-kalitok-neo, date of access 02/08/2023. The T-shaped profile has a closed cross section, made with the formation m cavity inside the T-shaped profile. The cross section is formed by a small wall, two first side walls, two transitional walls, two second side walls and a large wall. The two first side walls are arranged parallel to each other and to the second side walls. In this case, the first side walls are located at a smaller distance from each other than the second side walls. The small wall, the two transitional walls and the large wall are arranged generally parallel to each other. In this case, the transition walls are generally located in the same plane, the first side walls are interconnected on one side by a small wall located generally at a right angle to the first side walls. On the side opposite the small wall, each first side wall is connected to its corresponding transition wall. In this case, the transition walls are bent in opposite sides from each other with respect to the first side walls. The opposite edges of the transition walls are each connected to a corresponding second side wall. The second side walls are located on the opposite side from the plane of the transitional walls with respect to the first side walls. The opposite edges of the second side walls are connected to the large wall. A connecting seam is formed on the large wall. The connecting seam is formed by mutual engagement of the folded edges of the parts of the large wall for each other. Making the connection in this way leads to a large material consumption of the T-shaped profile.

The disadvantage of the known device is the high material consumption.

A device is known - a T-shaped profile, indicated in the source in the photo on the left on the website https://www.ivautoglass.ru/product/moldingi-i-klipsy/profil-universalnyy-tip-t4-fuyao-fyg-11763/, accessed 02/08/2023. The T-shaped profile is made with a closed cross section. In this case, a cavity is formed inside the profile. The cross section is formed by successively located small wall, one first side wall, one transitional wall, one second side wall, a large wall, another second side wall, another transitional wall, another first side wall connected to the previously indicated small wall. In this case, the transition walls are located in one plane parallel to the large wall. In this case, the small wall and the large wall are located on opposite sides of the plane of the transition walls. The first side walls are arranged parallel to each other between the transition wall plane and the small wall. The second side walls are arranged parallel to each other between the transition wall plane and the large wall. In this case, the distance between the first side walls is made smaller than the distance between the second side walls. The small wall is formed from two parts interconnected in the middle part. A connecting seam is formed on the outer side of the small wall, protruding above the outer surface of the small wall. In this case, the small wall is made curved outward of the profile, i.e. away from the cavity formed inside the profile. In this case, the protruding connecting seam can create additional stresses in the profile material, which can adversely affect the strength of the connection. In addition, by making the deflection formed on the small wall, the small wall is more susceptible to deformation.

The disadvantage of the known technical solution is the low strength and wear resistance.

The closest technical solution (prototype) is the T-shaped profile indicated in the source in the photo on the right on the website https://www.ivautoglass.ru/product/moldingi-i-klipsy/profil-universalnyy-tip-t4-fuyao-fyg-11763/, accessed 08.02.2023. The T-shaped profile is made with a closed cross section. In this case, a cavity is formed inside the profile. The cross section is formed by successively located small wall, one first side wall, one transitional wall, one second side wall, a large wall, another second side wall, another transitional wall, another first side wall connected to the previously indicated small wall. In this case, the transition walls are located in the same plane parallel to the small wall and the large wall. In this case, the small wall and the large wall are located on opposite sides of the plane of the transition walls. The first side walls are arranged parallel to each other between the transition wall plane and the small wall. The second side walls are arranged parallel to each other between the transition wall plane and the large wall. The distance between the first side walls is made smaller than the distance between the second side walls. In this case, the kink between each first side wall and the transition wall is made with the formation of a rounding of a large radius, which negatively affects the strength of the product as a whole.

The disadvantage of the prototype is the low bending strength.

The main elements of a three-dimensional T-shaped steel profile (hereinafter sometimes referred to as the device) are a small central wall 2, two first side walls 4, two transitional walls 6, two second side walls 8, a large central wall 9 and an intermediate element 13.

Volumetric T-shaped steel profile is made in the form of a long product, the length of which is much greater than the dimensions of its cross section. The device is made of sheet steel by bending to form several walls (small central wall 2, two first side walls 4, two transitional walls 6, two second side walls 8 and a large central wall 9). The indicated walls are located sequentially one after another with the formation in the transverse section of the closed circuit with the cavity 1. At the same time, the small central wall 2 is connected with one first side wall 4. This first side wall 4 is connected with one transitional wall 6. This transitional wall 6 is opposite to the edge of one second side wall 8. This one second side wall is connected to one edge with one edge. the large central wall 9. The large central wall 9 is connected by the opposite edge to the other second side wall 8. This other second side wall 8 is connected by the opposite edge to the other transition wall 6. This other transitional wall 6 is connected to the other first side wall 4. This other first side wall is connected to the other edge of the small central wall 2. At the same time, in the direction of the cavity 1, the inside is facing the inside. the nye surface is 15, and out the device - the outer surface is 11.

Each wall (small central wall 2, two first side walls 4, two transitional walls 6, two second side walls 8 and a large central wall 9) is made flat and is a plate.

The large central wall 9 is made in width larger than the small central wall 2, and also larger than each of the transitional walls 6. The large central wall 9 from two opposite edges is connected to the second side walls 8 with the formation of the fourth kinks 10. The fourth kinks 10 are generally made at right angles.

The second side walls 8 are located on one side of the plane of the large central wall 9. The second side walls 8 are generally parallel to each other. Each second side wall 8 on the side opposite to the large central wall 9 is connected to the transition wall 6 corresponding to this second side wall 8.

Transition walls 6 are located in the same plane. Each transitional wall 6 from the junction with the second side wall 8 is bent towards the other transitional wall 6 with the formation of the third bends 7. The third bends 7 are generally made at right angles. The edges of the transitional walls 6 opposite to the second side walls 8 are each connected to the first side wall 4 corresponding to this transitional wall 6.

The first side walls 4 are generally parallel to each other. The first side walls 4 are located on one side of the plane of the transition walls 6. The first side walls 4 are located at a smaller distance from each other than the second side walls 8. At the point of transition from the transition wall 6 to the first side wall 4, a second bend 5 is formed. The second bend 5 is generally made at a right angle. The first side walls 4 on the side opposite to the transitional walls 6 are connected to the small central wall 2.

The small central wall 2 is located between the first two side walls 4, attached to them by its opposite edges. At the point of transition of the small central wall 2 into the first side walls 4, first folds 3 are formed. The first folds 3 are generally made at a right angle. On the small central wall 2, the connection edges 14 are connected by means of an intermediate element 13. In this case, the intermediate element 13 is located in the groove.

The groove is located in the central part of the small central wall 2 along its entire length. Each connecting edge 14 is made with the formation of a bevel 12 and blunting. The surface forming the bevel 12 is located with the formation of an obtuse angle (more than 90°) with the outer surface 11 of the small central wall 2. The bluntness is formed from the side of the cavity 1. The location from the side of the cavity is understood as the location of the bluntness along the connecting edge 14 as a whole at a right angle to the inner surface 15 and at an obtuse angle to the bevel 12. In this case, a V-shaped groove is formed between the bevels 12, which is a trench ku.

The intermediate element 13 is a part of the structure of the device, providing a permanent connection of the connecting edges 14 with the formation of a closed loop in the cross section. The intermediate element 13 is located between the bevels 12 and, in the particular case, partly between the blunt. The intermediate element 13 is flush with the outer surface 11 and the inner surface 15. The intermediate element 13 is integral with the connecting edges 14 of a material obtained by heating the melt and further cooling to form new crystal lattices. In this case, the material of the intermediate element 13 may differ from the material of the connecting edges 14 in terms of the structure of their crystal lattices. The differences are due to different temperatures of heating, melting and cooling, and also, in the case of welding using an electrode, due to the introduction of other elements into the composition of the intermediate element 13 in the form of electrodes used in the fusion (welding) of the connecting edges 14.

Thus, the small central wall 2, the transitional walls 6 and the large central wall 9 are generally parallel to each other. The first side walls 4 and the second side walls 8 are generally parallel to each other.

Implementation of the utility model

In the case of using the above elements and means, the invention is implemented as follows (the presented description of the object illustrates a particular case of its execution, other implementations are possible using the features of this technical solution).

Prepare sheet material (steel sheet) for the manufacture of the device. Opposite edges of the steel sheet (joining edges 14) are cut at an angle to form bevels 12 on the side of one surface of the steel sheet of the largest area and blunts on the side of the other surface of the steel sheet of the largest area. In this case, the surface forming the bevel 12 is located with the formation of an obtuse angle (more than 90°) with the outer surface 11, and the bluntness with the formation of a right angle with the inner surface 15.

A device is made from sheet material by deformation. In this case, fourth bends 10 are performed between the large central wall 9 and the second side walls 8 with an angle of more than 90°. The second side walls 8 are folded to one side of the large central wall 9. The second side walls 8 are arranged generally parallel to each other. Perform the third bends 7 between the second side walls 8 and transitional walls 6 with an angle of less than 90°. The transition walls 6 are bent towards each other and placed in the same plane. Perform the second kinks 5 between the transition walls 6 and the first side walls 4 with an angle of 90°. In this case, the first side walls 4 are arranged on one side of the plane of the transition walls 6. The first side walls 4 are generally arranged parallel to each other. Perform the first bends 3 between the first side walls 4 and the small central wall 2 with an angle of 90°. Parts of the material forming a small central wall 2 are directed towards each other and placed in the same plane. When this connecting edges 14 are in contact with each other blunt. Bevels 12 form a groove.

Due to the arrangement of adjacent (contacting, adjacent) walls perpendicular to each other, the bending strength of the profile is increased. So, for example, when adjacent walls are located at an angle other than 90° under external action, adjacent walls sag with less force, which leads to faster bending of the device as a whole.

Next, the joining edges 14 of the sheet material are joined, for example by welding, to form an intermediate element 13 or by friction welding of the intermediate element 13 . When this occurs, the heating process of the connecting edges 14 and the electrode or the connecting edges 14 and the intermediate element 13, respectively. In the case of welding, the electrode and the material of the connecting edges 14 form a metal alloy filling the groove. At the same time, due to the implementation of blunts from the side of the inner surface 15, the product is protected from burning through and penetration of the molten alloy onto the inner surface 15. In addition, the blunts are partially connected to each other due to heating and fusion of the materials of the connecting edges 14. Thus, a more uniform structure of the material of the welded joint is obtained along the entire length of the connecting edges 14 and the intermediate element 13. During cooling (in the case of using an electrode), crystallization occurs and a solid permanent connection of the connecting edges is formed. 14 in the form of an intermediate element 13. The intermediate element 13 is integral with the material of the connecting edges 14, i. represents a single structural element, and is flush with the outer surface 11 of the small central wall 2. At the same time, from the side of the inner surface 15, a continuous layer of metal is provided without inclusions obtained from the electrode, i.e. with a homogeneous structure, which increases the strength of the device as a whole. This feature is provided by performing blunting on the connecting edges 14.

Volumetric T-shaped steel profile in a particular case, for example, is used as elements of enclosing structures, in particular fences. From these profiles, a rectangular frame is made, inside which a sheet is installed, for example, from metal. The sheets are fastened to the first side wall 4 by any known method applicable in the art. Including, for example, by means of self-tapping screws or a welded joint.

Due to the location of the intermediate element 13 flush with the outer surface 11 and the inner surface 15, a more even and uniform wall is obtained without protruding elements and deflections, which can lead to further deformation of the wall under external influence.

The presence of an intermediate element 13 in the structure in the small central wall 2 provides a built-in stiffener, which increases the bending strength of the device.

Thus, the implementation of the device with a set of essential features described in the formula, provides an increase in the strength of the bulk T-shaped steel profile for bending. Ensuring the technical result is achieved by arranging adjacent walls orthogonally to each other, as well as by making the walls smooth, without deflections and protruding elements. The increase in the strength of the device as a whole is also affected by the absence of foci of burning, which provides a connecting seam with a uniform structure along its entire length.
