Description

The invention relates to the field of industrial and civil engineering and is intended for fastening profiles of mounted facade systems.

Bracket designs for mounting profiles of curtain wall systems are known (certificates for a utility model of the Russian Federation: 40066, class E04F 13/08; 77312, class E04F 13/08; 69115, class E04F 13/08; 14235, E04F 13/08) containing an L-shaped plate. The bracket plate has holes for mounting the profiles located on the first shelf of the plate, as well as holes for mounting the bracket located on the second shelf of the plate forming the rear wall of the bracket. The disadvantages of such brackets are due to their asymmetric shape. The holes for mounting the bracket are offset from the axis of the cantilever part of the plate and are located asymmetrically relative to this axis. When the bracket is exposed to loads along the axis of the cantilever part of the plate, the load is transmitted to the fastener with the formation of torque and leads to a loss of stability of the bracket-wall mount. This reduces the reliability of operation of the brackets. In the cross section of the brackets, additional stresses arise due to the displacement of the place of attachment of the brackets relative to the axis of application of the load to the cantilever part of the plate. To compensate for these stresses, it is necessary to increase the cross-sectional area of the plate, for example its thickness, which increases the metal consumption of such products.

When the cantilever part of the plate is located vertically or horizontally, the brackets under consideration have a relatively low load capacity and reliability when exposed to horizontal or vertical loads, respectively, which also leads to an increase in the metal consumption of such products due to the need to increase the cross-sectional area of the plate, for example, by increasing the thickness of the plate. An increase in the thickness of the plate leads to an increase in the radius of bending of the plate and, consequently, to an increase in the width of the back wall and to a shift in the places of attachment of the bracket from the axis of the cantilever part of the plate, and therefore to limit the load capacity of the brackets.

In addition, the plate of such brackets, as a rule, has the same thickness (cross-sectional area) in the cantilever part and in the rear wall. When loading the brackets, the voltage in the rear wall is greater than in the console part. To ensure the required load capacity of the brackets, the thickness (cross-sectional area) of the plate is selected in accordance with the stresses in the rear wall of the bracket. In this case, the cantilever part of the plate remains underloaded, i.e. Excessive metal consumption of the cantilever part of the plate. Thus, in the brackets under consideration there is a non-optimal use of the material, and consequently, their cost increases.

Bracket designs are also known (certificates for a utility model of the Russian Federation: 80480, class E04F 13/08; 60555, class E04F 13/08) containing a U-shaped plate, on the console parts of which holes are made for attaching profiles of the curtain wall system, and on the central shelf of the plate forming the rear wall of the bracket, holes are made for mounting the bracket. The width of the rear wall of such brackets is determined by the width of the profiles of the hinged facade system and cannot be optimized with respect to the length of the cantilever part (the length of the cantilever part may have different values depending on the required extension of the hinged facade system from the wall of the building). Therefore, such brackets have a limited bearing capacity.

In addition, such brackets have a limited bearing capacity with a vertical arrangement of the cantilever part and the effect of horizontal loads, because the distance from the center of the hole on the rear wall to the base of the cantilever part is generally less than the distance from the back wall to the center of the holes on the cantilever part. The distance from the center of the hole on the rear wall to the base of the cantilever part is unchanged and is determined by the width of the profiles of the curtain wall system. All this leads to the need to increase the thickness (cross-sectional area) of the plate to provide the necessary bearing capacity of the brackets, i.e. to increase the intensity of such products. With the same thickness (cross-sectional area) of the material in the cantilever part and in the rear wall and when the bracket is loaded with a vertical load, the cantilever part of the plate remains underloaded, i.e. excessive metal consumption of the cantilever part of the plate takes place, which leads to a relative increase in the cost of the brackets. In addition, the number of mounting points of the brackets is limited due to the limited width of the rear wall, which also limits their bearing capacity and reliability. The holes for mounting brackets are located between the console parts and far from their ends, which worsens their performance due to difficulties in mounting brackets, as well as if necessary to adjust the location of the bracket on the wall of the building.

Closest to the proposed one is a bracket for fastening profiles (certificate for utility model RF 8722, class ЕВВ 3/54), containing a back wall with holes for mounting a bracket and a L-shaped plate, the first shelves of which are designed for fastening profiles, the second shelf of the plates are directed from the axis of symmetry of the bracket.

L-shaped plates are rigidly interconnected using an additional plate, for example, by welding and the second shelves are rigidly attached to an intermediate element made in the form of a plate and which is the rear wall of the bracket. Holes for fixing the bracket are made on the intermediate element.

When loading such an arm with a vertical or horizontal load applied to the cantilever part of the L-shaped plates, the load is transferred to their second shelves and through fasteners to the intermediate element. On the shelves of the L-shaped plates, as well as on the plate of the intermediate element in the places where the bracket is attached, stresses occur proportional to the load applied to the cantilever part of the plates. The thickness (cross-sectional area) of the L-shaped plates and the plate of the intermediate element is selected from the conditions for ensuring acceptable voltage values. At the same time, on the plate of the intermediate element, the greatest stresses arise at the places of attachment of the bracket. Moreover, in the middle part of the intermediate element and the bracket itself, excessive metal consumption is obtained, which leads to a rise in the cost of such products. Actually the presence in the bracket of an intermediate element in the known device does not increase the load capacity of the bracket and is expensive.

Thus, the considered bracket has excessive metal consumption and limited bearing capacity and reliability.

The aim of the invention is to reduce the metal consumption, increase the bearing capacity and reliability of the bracket.

To achieve this goal, in the bracket for mounting profiles, containing the back wall with holes for mounting the bracket and the plate is L-shaped, the first shelves of which are designed for mounting profiles, while the second shelves of the plates are directed from the axis of symmetry of the bracket in the central part of the back wall and bent in the direction of the shelf profiles perpendicular to the plane of the rear wall, and the second shelf of the plates are parallel to the rear wall from its back side, while the front side of the back wall the wafer is facing in the direction of the profiles, and the first shelves of the plates are parallel to the shelves of the rear wall and rigidly connected to them, and the edges of the corners formed by the plane and the shelves of the back wall are located in the inner corners of the plates, in addition, holes on the second shelves of the plates coincide with holes for mounting the bracket on the rear wall.

The shelves of the rear wall are cut out and bent so that two windows are formed in the central part of the rear wall, which are located symmetrically relative to the axis of symmetry of the bracket and separated by a strip lying in the plane of the rear wall.

As an option, an additional plate can be inserted into the bracket, and additional holes for fixing the bracket are made in the strip separating the windows in the rear wall, while the additional plate has holes and is parallel to the strip separating the windows in the rear wall, from its back side moreover, the holes in the additional plate coincide with the holes in the strip dividing the windows in the rear wall.

Flanges are made on the rear wall in the direction of the profiles, the planes of which are perpendicular to the plane of the first shelves of the L-shaped plates.

Alternatively, corners can be inserted into the bracket, installed in the internal corners formed by the plane and the shelves of the rear wall, while the first shelves of the corners are parallel to the shelves of the rear wall and rigidly connected to them, and the second shelves of the corners are parallel to the front of the rear wall and have holes matching the holes for mounting the bracket on the back wall.

The first shelves of the L-shaped plates consist of a movable and fixed parts, while the fixed part of the first shelf is connected to the second shelf of the plate, and the movable part of the first shelf is designed for fastening profiles.

The movable and / or fixed parts of the first shelves of the L-shaped plates are made with flanges to move the movable part along the length of the fixed part of the first shelves of the plates.

The first shelves of the L-shaped plates have bends, the plane of which is parallel to the profiles.

The moving parts of the first shelves of the L-shaped plates have limbs, the plane of which is parallel to the profiles.

The first and / or second shelves of the L-shaped plates and / or the rear wall and / or its shelves have stiffeners, and the stiffeners on the first shelves of the plates are located along the axis of symmetry of the bracket.

The ribs on the shelves of the plates coincide with the ribs on the back wall and its shelves.

The ribs on the second shelves of the plates are a continuation of the ribs on the first shelves of the plates.

A U-shaped profile can be introduced into the bracket, the middle shelf of which is located in the central part of the rear wall from its back side and is in the same plane as the second shelves of the L-shaped plates, while the extreme flanges of the U-shaped profile are parallel to the first shelves of the G plates -shaped and the shelves of the rear wall, as well as rigidly connected to them.

In the middle shelf of the U-shaped profile, holes for mounting the bracket are made. The extreme flanges of the U-shaped profile, the flanges of the rear wall and the first flanges of the L-shaped plates have matching stiffeners.

One or two pads can be inserted into the bracket, the central shelf of which is made with bends parallel to the rear wall and having holes matching the holes for mounting the bracket on the rear wall, the central shelf being perpendicular to the rear wall and the first shelves of the L-shaped plates, except of this, the central shelf has bends parallel to the first shelves of the L-shaped plates and tightly placed between them, while bends parallel to the rear wall are placed on its front side.

The limbs of the central flange of the lining are rigidly connected to the first shelves of the plates of the L-shaped and / or with the shelves of the rear wall.

A rigid connection can be made by welding or riveting.

The ribs can be made in the form of moldings and / or flanges.

The invention is illustrated by drawings. Figure 1 shows an example of the use of the bracket for attaching profiles of the curtain wall system, figure 2 shows a General view of the bracket, figure 3 shows the design of the bracket, figure 4 shows the movable and fixed parts of the plates of the L-shaped form of the bracket, figure 2 .5 a bracket with overlays is shown.

The bracket 1 (Fig. 1) for fastening the profiles 2 of the curtain wall system to the wall of the building 3 contains a rear wall 4 (Fig. 2) with holes 5 for fastening the bracket 1 and plates 6 of the L-shaped form, the first shelves 7 of which are intended for fastening the profiles 2 (FIG. 1). In this case, the second shelves 8 (Fig. 3) of the plates 6 are directed from the axis of symmetry 9 of the bracket. In the central part of the rear wall 4, shelves 10 are cut and bent in the direction of the profiles 2 (FIG. 1), perpendicular to the plane of the rear wall 4 (FIG. 2, FIG. 3). The second shelves 8 of the plates 6 are located parallel to the rear wall 4 from its reverse side, while the front side 11 of the rear wall 4 is facing in the direction of the profiles 2 (figure 1). The first shelves 7 (Fig. 3) of the plates 6 are parallel to the shelves 10 of the rear wall 4 and are rigidly connected to them, for example, by rivets 12. The edges of the corners formed by the plane and the shelves 10 of the rear wall 4 are located in the inner corners of the plates 6. In addition, on the second shelves 8 of the plates 6 holes are made matching the holes 5 for mounting the bracket on the rear wall 4.

With this embodiment, the design of the bracket optimally uses the material in the rear wall 4 (figure 2). In the Central part of the rear wall 4, where less stress occurs when loading the bracket 1 (Fig. 1) from the side of the profiles 2, the shelves 10 are cut down and bent (Fig. 2). When loading the bracket 1 (Fig. 1) from the side of the profiles 2, the greatest stresses occur at the places of its fastening (part of the back wall 4 with holes 5 in Fig. 2 and second shelves 8 of the plates 6) and near the base of the shelves 7 (Fig. 3) of the plates 6. However, in the proposed bracket design in these areas, the cross-sectional area (equivalent thickness) is increased due to the rigid connection (for example, using rivets 12) of the shelves 10 of the rear wall 4 with the first shelves 7 of the plates 6, as well as the rigid connection of the second shelves 8 of the plates 6 with a back wall 4 in places of fastening of a cro Matte 1 (Figure 1) to the building wall 3, because the holes on the second shelves 8 (Fig. 3) of the plates 6 coincide with the holes 5 for mounting the bracket on the rear wall 4. Thus, in places of greatest stresses in the bracket, the cross-sectional area is increased without using additional materials by using material from the underloaded area of the bracket. This allows you to increase the bearing capacity and reliability of the bracket and reduce its metal consumption. In addition, with a rigid connection of the rear wall 4 (Fig. 3) and the shelves 7 and 8 of the plates 6, the load from the profiles 2 (Fig. 1) on the bracket 1 is redistributed between the first shelves 7 of the plates 6 and the shelves 10 of the rear wall 4, as well as between the second shelves 8 of the plates 6 and the rear wall 4 in the places of mounting the bracket through the holes 5. All this, by optimizing the thickness of the rear wall 4 and the plates 6, to ensure the maximum reduction in metal consumption of the bracket at the given loads, and also increase the bearing capacity and reliability with minimal metal-intensive ti bracket.

The shelves 10 (Fig. 3) of the rear wall 4 can be cut down and bent so that two windows 13 and 14 are formed in the central part of the rear wall 4, which are located symmetrically relative to the axis of symmetry 9 of the bracket and separated by a strip 15 lying in the plane of the rear wall 4 .

With this embodiment of the shelves 10 of the rear wall 4, it is possible, by optimizing the sizes of the shelves 10, to reduce the metal consumption of the bracket and increase its bearing capacity and reliability.

An additional plate 16 can be inserted into the bracket (Fig. 3, embodiment), and in the strip 15. Separating windows 13 and 14 in the rear wall 4, additional holes 17 are made for fixing the bracket, while the additional plate 16 has holes and is parallel strip 15 from its rear side, and the holes in the additional plate 16 coincide with the holes 17 in the strip 15.

In this embodiment of the bracket, it is recommended to choose the thickness of the additional plate 16 equal to the thickness of the plates 6. In this case, the additional plate 16 and the second shelves 8 of the plates 6 form a plane uniformly adjacent to the wall of the building 3 (Fig. 1) when fixing the bracket 1 through additional holes 17 ( figure 3). The presence in the bracket of additional holes 17 increases the bearing capacity and reliability of the bracket.

On the rear wall 4 (FIG. 3) in the direction of the profiles 2 (FIG. 1), flanging 18 (FIG. 3) can be made, the planes of which are perpendicular to the plane of the first shelves 7 of the plates 6.

The presence of flanges 18 on the rear wall 4 increases the rigidity and strength of the rear wall 4 and increases the bearing capacity and reliability of the bracket without increasing metal consumption.

Corners 19 (FIG. 3) can be inserted into the bracket, installed (shown by arrows in FIG. 3) at the internal corners formed by the plane and shelves 10 of the rear wall 4, while the first shelves 20 of the corners 19 are parallel to the shelves 10 of the rear wall 4 and rigidly they are connected (for example, with rivets 12), and the second corner shelves 21 are parallel to the front side 11 (Fig. 1) of the rear wall 4 (Fig. 3) and have holes matching the holes 5 for mounting the bracket on the rear wall 4.

This technical solution allows to increase the cross-sectional area (equivalent thickness) in the areas of greatest stresses in the bracket 1 when it is loaded from the side of the profiles 2 and, therefore, increase the bearing capacity and reliability of the bracket. A rigid connection of the corners 19 (Fig. 3), the rear wall 4 and the shelves 7 and 8 of the plates 6 leads to a redistribution of the loads between them from the side of the profiles 2 (Fig. 1) to the bracket 1. This allows, optimizing the thickness of the corners 19, as well as the back walls 4 and plates 6, to provide high load-bearing capacity and reliability with minimum metal consumption of the bracket, as well as reduce the metal consumption of the bracket at a given load.

In the bracket, the first shelves 7 (FIG. 2) of the plates 6 can be made of movable 22 (FIG. 4) and fixed 23 parts, while the fixed 23 part of the first shelf 7 is connected to the second shelf 8 of the plates 6 (FIG. 3), and movable 22 part (figure 4) of the first shelf 7 is intended for mounting profiles 2 (figure 1).

Movable 22 (figure 4) and / or fixed 23 parts of the first shelves 7 of the L-shaped plates can be made with flanges 24 to move the movable 22 part along the length of the fixed 23 part of the first shelves 7 of the plates.

This embodiment of the bracket provides the convenience of mounting profiles 2 (Fig. 1) and the curtain wall system as a whole on the wall of the building 3, because allows you to accurately set the plane of the profiles 2 (the plane of the facade system as a whole) regardless of the irregularities of the wall of the building 3 by moving the movable 22 part of the first shelf 7 (Fig. 4) along the fixed 23 part. The movement of the movable 22 part of the first shelf 7 along the stationary 23 part can be achieved, for example, by flanging 24. The plane of the facade system is aligned without applying any additional loads to the bracket, and therefore, its high reliability and bearing capacity are ensured.

The first shelves 7 (Fig. 4) of the L-shaped plates can have limbs 25. The plane of which is parallel to the profiles 2 (Fig. 1).

When mounting the hinged facade system, the profiles 2 are installed until they stop in the bends 25 (Fig. 4) on the first shelves 7 (or on their moving parts 22) of the L-shaped plates and are attached to the first shelves 7 of these plates, for example, using rivets. If the first shelves 7 consist of a movable 22 and a fixed 23 parts, then the plane of the profiles 2 (Fig. 1) and the plane of the facade system are aligned, then the movable 22 (Fig. 4) and the fixed 23 parts of the shelves 7 of the L-shaped plates are fixed (fastened) together, for example, using rivets. This embodiment of the bracket accelerates the installation process of profiles 2 (figure 1) and the curtain wall system as a whole.

The first 7 (figure 3) and / or second 8 shelves of the plates 6 and / or the rear wall 4 and / or its shelves 10 may have stiffeners (respectively 26 and / or 27, and / or 28, and / or 29), moreover, the ribs 26 on the first shelves 7 of the plates 6 are located along the axis of symmetry 9 of the bracket.

The presence of stiffeners 26, 27, 28, 29 increases the stiffness and strength, respectively, of the first shelves 7 of the plates 6, their second shelves 8, the rear wall 4, its shelves 10. This increases the bearing capacity and reliability of the bracket without increasing metal consumption.

The ribs 26 and 27 on the shelves 7 and 8 of the plates 6, it is recommended to perform so that they coincide (as shown in figure 2 and 3) with ribs on the rear wall 28 and its shelves 10, respectively.

This embodiment of stiffening ribs allows you to most effectively increase the bearing capacity and reliability of the bracket without increasing metal consumption.

It is no less effective to perform stiffeners 27 (Fig. 3) on the second shelves 8 of the plates 6 so that they are a continuation of the stiffeners 26 on the first shelves 7 of the plates 6.

This embodiment of stiffeners not only increases the bearing capacity and reliability of the bracket without increasing the metal consumption, but also is the most technologically advanced solution in the manufacture of the bracket.

A U-shaped profile 30 (FIG. 2) can be inserted into the bracket, the middle shelf 31 (FIG. 3) of which is located in the central part of the rear wall 4 from its reverse side and is in the same plane with the second shelves 8 of the L-shaped plates 6 forms, while the extreme flanges 32 of the U-shaped profile 30 (FIG. 2) are parallel to the first flanges 7 (FIG. 3) of the L-shaped plates 6 and the flanges 10 of the rear wall 4, and are also rigidly connected to them (for example, by rivets 12).

This technical solution allows to increase the cross-sectional area (equivalent thickness) near the base of the shelves 7 of the plates 6, i.e. in places of greatest tension in the bracket 1 (Fig. 1) when it is loaded from the side of the profiles 2. In addition, with a rigid connection of the extreme shelves 32 of the profile 30, the first shelves 7 of the plates 6 and the shelves 10 of the rear wall 4, the load from the profiles 2 (Fig. 1) on the first shelves 7 (Fig. 3) of the plates 6 is redistributed between the middle shelf 31 of the profile 30 and the mounting points of the bracket (parts of the rear wall 4 with holes 5 and the second shelves 8 of the plates 6). This improves the bearing capacity and reliability of the bracket. By optimizing the thickness of the plates 6, profile 30 and the back wall 4, it is possible to maximize the bearing capacity and reliability with minimal metal consumption of the bracket.

Moreover, in many practical cases, it is recommended to choose the thickness of the profile 30 equal to the thickness of the plates 6 to ensure a uniform fit of the bracket 1 (figure 1) to the wall of the building 3.

In the middle shelf 31 (FIG. 3) of the U-shaped profile 30, holes for fixing the bracket can be made. In this case, it is recommended to choose the thickness of the profile 30 equal to the thickness of the plates 6. In this case, the middle shelf 31 of the profile 30 and the second shelves 8 of the plates 6 form a plane uniformly adjacent to the wall of the building 3 (Fig. 1) when attaching the bracket 1. If there is a central part the rear wall 4 of the strip 15, dividing the windows 13 and 14, the holes in the middle shelf 31 of the profile 30 for mounting the bracket coincide with the holes 17 in the strip 15.

The holes for mounting the bracket in the middle shelf 31 of the profile 30 increase the bearing capacity and reliability of the bracket.

The extreme flanges 32 (FIG. 3) of the profile 30 (FIG. 2) may have stiffeners 33 matching the stiffeners 26 and 29, respectively, on the first shelves 7 of the plates 6 and on the shelves 10 of the rear wall 4.

The presence of stiffeners 26, 29, 33 increases the stiffness and strength, respectively, of the first shelves 7 of the plates 6, shelves 10 of the rear wall 4 and the extreme shelves 32 of the profile 30. This increases the bearing capacity and reliability of the bracket without increasing metal consumption.

One or two pads 34 (FIG. 5) can be inserted into the bracket, the central shelf 35 of which is made with bends 36 parallel to the rear wall 4 and having openings 37 coinciding with the holes 5 for mounting the bracket on the rear wall 4. Moreover, the central shelf 35 perpendicular to the rear wall 4 and the first shelves 7 of the plates 6 L-shaped. In addition, the Central shelf 35 has bends 38 parallel to the first shelves 7 of the plates 6 and tightly placed between them. In this case, the bends 36 parallel to the rear wall 4 are placed on its front side 11 (Fig. 1).

The number (one or two) of the pads 34 (figure 5) is determined depending on the loads acting on the bracket, according to the results of static calculation. Pads 34 increase the stability of the bracket with lateral (horizontal) loads on it. This is ensured by the tight placement of the bends 38 of the central shelf 35 between the first shelves 7 of the plates 6, which prevents the movement of the shelves 7 of the plates 6 with lateral loads on the bracket. This increases the bearing capacity and reliability of the bracket. In addition, the pads 34 have a rigid connection with the rear wall 4 in the places of mounting the bracket through the holes 5 in the rear wall 4 and the holes 37 in the bends 36 of the central shelf 35 and thereby strengthen the rear wall 4 and increase the bearing capacity and reliability of the bracket. At the same time, the rib between the central shelf 35 and its bends 36 with a rigid connection of the cover plate 34 and the rear wall 4 also strengthens the rear wall 4 and increases the bearing capacity and reliability of the bracket.

The bends 38 and 36 (Fig. 5) of the central shelf 35 of the lining 34 can be rigidly connected (for example, using rivets) with the first shelves 7 of the plates 6 (bends 38) and / or with the shelves 10 of the rear wall 4.

This implementation of the design of the bracket most effectively increases the stability of the bracket, as well as its bearing capacity and reliability.

In the considered bracket designs, the most technologically advanced stiffeners are made in the form of moldings and / or flanges. Hard joints are recommended by welding or riveting.

Thus, the invention allows to reduce the metal consumption, to increase the bearing capacity and reliability of the bracket.
