Description

This utility model relates mainly to storage equipment, in particular, to racks used in the construction of racks made of profiles.

Shelving racks are known from the patent documentation, each of which in cross section contains front and side walls perforated with holes (US 2014175036 A1, 06/26/2014. US 2013067734 A1, 03/21/2013. 2011278251 A1, 11/17/2011. 2011155679 A1, 30.06. 2011. MY 123787 A, 06/30/2006. SK 120010 U1, 08/09/2010. CN 101574200 A, 11/11/2009).

A profile is known that is used for the manufacture of vertical racks of a collapsible rack (RU 58314 U, 11.27.2006), each rack of which is made of a perforated profile with rounded corners, the profile having a base (front wall) and two stepped side walls adjacent to it moreover, the width of the base is greater than the width of the stepped side walls. When mounting racks, the vertical racks are oriented by their bases (front walls) along the shelves of the rack, the length of which is several times greater than their width. When mounting racks, the transverse beams are deepened into the internal cavity of each rack and fixed with screws between the walls in the zone of their maximum convergence. This end contact zone is not deep enough to securely fix the transverse beams, which negatively affects the rigidity of the rack structure. To attach the transverse shelves, special devices are used, for example, hanging hooks.

For the manufacture of these known racks used the profile according to patent RU 30249, 06/27/2003, having a box-shaped cross-sectional shape - with a base and two side walls adjacent to it. A curved longitudinal groove is made on the basis of the profile, trapezoidal longitudinal folds concave into the profile on the side walls along the edge. Flanging is made on the edges of the side walls, the edge of which is parallel to the base. On the walls and on the basis of the profile there are rows of perforations. As indicated in the patent, a vertical rack rack is made from this profile. The main disadvantage of this design, as well as other known analogues, is that for mounting the transverse shelves, the use of separate fasteners is required.

Known rack rack (RU 64872 U1, 07.27.2007), containing perforated front and side walls, each side wall is made stepped, tapering away from the front wall with the formation between the ends of the side walls of the longitudinal groove for the location of the cross of the rack.

RU 64872 U1 discloses a storage rack including racks made in the form of steel profiles, on the front surfaces of which holes are made having wedge-shaped sections, beams made in the form of hollow elements having end surfaces with holes, latches installed in the combined holes of the racks and beams, connecting elements installed with the possibility of fixing the beams on the racks, and the wall thickness of the steel profile of the rack is from 2 to 3 mm, the upper part of the holes having a wedge-shaped e sections, made of rectangular shape, while at least on one surface a stiffener is made in the form of a longitudinal recess, the hollow beam element is made of sheet steel with a thickness of 1 to 3 mm, while at least one of its sides is located , two stiffeners, made in the form of longitudinal gutters, connecting elements are made on the end surfaces of the beam and are formed by cut metal surfaces of the end surfaces of the beam, bent towards each other, the connecting elements behind iksirovany wedge portions in holes formed on the front surfaces of racks, a rack is provided with braces that connect pairs of adjacent posts, as well as means for fixing the uprights on the horizontal surface.

Means for fixing the racks on a horizontal surface are made in the form of plates installed under the base of each rack and connected to the rack and floor using fasteners.

The patent RU 64872 U1 also presents a rack of a storage rack made in the form of a steel profile having a frontal surface on which openings having wedge-shaped sections are located, the upper part of the holes having a rectangular shape, the wall thickness of the steel profile of the rack is from 2 to 3 mm, however, at least one surface of the profile is made of a stiffener in the form of a longitudinal recess.

RU 64872 U1 also discloses a storage rack beam made in the form of a hollow element having end surfaces with holes, the hollow element being made of sheet steel with a thickness of 1 to 3 mm, with at least two located on its side surface stiffening ribs made in the form of longitudinal gutters, connecting elements are formed on the end surfaces of the beam, formed by the cut metal surfaces of the end surfaces of the beam, bent towards each other

Of the known racks, to the rack rack presented in this description, is a rack rack made of a box type profile (RU 101522 U1, 01.20.2015) having a base (front wall) and two side walls adjacent to it, based on a longitudinally oriented the groove is perforated on the side walls and on the base, and hooks are made on the side walls, oriented along the wall surface and formed by a notch with an open loop with a bend to the outside of the cut part. Hooks have a relief shape with reinforcing elements. Hooks have stiffeners made in the form of a longitudinal corrugation.

RU 101522 U1 also provides a rack, characterized in that it is made of the specified profile in accordance with the independent claim 1 of the formula of the said patent and all profile signs are used in the rack.

Patent RU 101522 U1 adopted as a prototype of this utility model. Significant features of the prototype, similar to the features of a utility model, are such signs that the rack rack contains front and side walls, hooks bent outwardly made on each side wall, each side wall is stepped and an opening under the cross-section of the rack is formed between the steps of the side walls while the lower end of the rack is equipped with a support connected to it with a bottom and a hole in it for the latch.

A significant disadvantage of the prototype is that the prototype strut has an unsatisfactory bearing capacity and in this regard, its resistance to bending loads is insufficient. This is due to the many holes in the front wall of the rack, which are located in the planes of the holes of the side walls, which significantly reduces the total cross-sectional area of the metal of the rack and, accordingly, reduces the resistance of the rack to bending from vertical both static and dynamic loads. As practice has shown, the presence of a groove on the front wall complicates the design of the rack, does not affect the stability of the rack and its resistance to bending loads. It should also be noted that the support located under the rack, connected by bolts to the side walls of the support, provides insufficient stability of the rack from the shear forces applied to it in the directions across the rack or across the rack, which leads to the displacement of the rack relative to its working design position. The displacement of the rack racks from the specified working position is the reason for the loss of stability of the rack, which does not meet the safety conditions.

The technical result of the utility model is to increase the bearing capacity of the rack.

The technical result was obtained by a rack rack containing front and side walls, hooks bent outwardly made on each side wall according to its height, each side wall is made stepwise and between the steps of the side walls there are formed openings for the rack beams, while the lower end of the rack is equipped with a support connected to it with a bottom and a hole in it, and at each end of the side wall a stiffener is made in the form of a flanging of the end of the side wall, extending along the rack from its outer side, the front wall is made It is flat, the aforementioned support in cross section has a closed cup shape with perimeter edges and an opening located inside the cup, the end of the rack is located in a closed contour of the support and is rigidly connected to the support, and the upper end of the rack is equipped with a support identical in shape to it located mirrored with respect to the lower support.

In FIG. 1 shows a stand in an upright working position;

In FIG. 2 shows a pair of racks connected by racks;

In FIG. 3 - the lower part of the rack with support at its end, place A in FIG. 2;

In FIG. 4 - stand in cross section, BB in FIG. one;

In FIG. 5 is a section BB in FIG. 3 (fragment);

In FIG. 6 shows the relative position of the racks installed in the tier.

The rack rack (Fig. 1) is made of one steel sheet strip by stamping and bending. It contains a front wall 1 and side walls 2 and 3 (Fig. 3), moreover, on each side wall along its entire height there are hooks 4 bent outwardly obtained by cuts in the side wall. Each hook 4 in a side view has a wave-like shape with an end bent from the stand, and in a side view, each hook has a semicircular top edge.

The front wall 1 of the rack is made flat. Each side wall has a stepped shape in projection onto a horizontal plane (Fig. 4). The stepped shape of each wall is formed by the front step 5 (Fig. 3) and the rear step 6 of the wall, while there is an inclined jumper between the steps. The rear steps 6 of the side walls are brought together so that the width s between them (Fig. 4) is less than the width between the steps 5 of the walls. Steps 5 and 6 of one side wall are located in different planes.

In the front wall 1 (Fig. 1), mounting holes 7 are made for the screed of the rack (not shown).

Each side wall has a flange 8 on its free side side (FIG. 4) in the form of a longitudinal section of the side wall rotated through 180 °. Flange 8 forms a thickening, which performs the functions of stiffeners and reinforced places for holes 9 (Fig. 4). The holes are intended for the location in them of the fastening elements of the beam 18 of the rack (Fig. 3) to the side walls 2 and 3 of the rack. For this, an opening s is formed between the steps 6 of the side walls, the width of which is equal to the thickness of the beam 18 (the beam 18 is not included in the structure of the rack and is shown in the drawings as an illustrating element interacting with the rack).

Flanging 8 (Fig. 4) extends along the height of the rack and along it, it is located on the outside of each side wall. In one design, the flange 8 fits snugly against the side wall 3 of the rack. In another preferred embodiment of the stand between the flange 8 and the side wall, a gap is formed over the entire height of the stand in order to eliminate microcracks at the bend of the flange 8. In this case, the place of its bend is made in a radius equal to the thickness of the sheet or more than the thickness of the sheet from which it is made rack. In each flanging 8 and in the side wall to which the flanging is adjacent, a plurality of holes 9 are made under the fastening elements to the rack of the rack beams.

A stamped support 10 (Fig. 3) is made rigidly fixed at the lower end of the rack, made of a thicker sheet in comparison with the sheet from which the rack is made. The support 10 has side flanges 11, a front flange 12 and a rear flange 13, as well as a bottom 14 (Fig. 4). The height of the side walls is made based on their tight fit at the end of the rack. The support is made in the form of a rectangular cup with rounded corners and is made by drawing metal during stamping.

The lateral sides 11 of the support fit snugly against the side walls 2 and 3 of the rack and are connected to them by fasteners (Fig. 4). The front side 12 of the support fits snugly against the front wall 1 of the rack, the rear side 13 fits to the ends of the side walls, and the bottom end of the rack rests on the bottom 14 of the support. A hole 15 for an anchor (not shown) is made in the bottom 14 of the support, the hole 15 is located inside the support, in the contour of its bottom. The support 10 is located on the floor 17 of the room. Each support 10 is connected to the walls 1-3 of the rack by fasteners inserted into the holes 19 of the rack (Fig. 3, fasteners not shown). In other versions of the rack, this connection can be carried out by resistance welding or by press-fitting the support on the end of the rack.

At the upper end of the rack, the upper support 10 is mirrored in a similar manner, the design of which is identical to the lower support shown at the lower end of the rack.

The rack works as follows. The rack is manufactured, transported, and installed in a working position in the form in which it is shown in FIG. 1 - with supports 10 fixed at its ends, which eliminates damage to the end edges of the rack, jamming of its corners, bends of the longitudinal edges of the rack and dangerous contacts with the sharp end angles of the rack.

Install a pair of rack racks connected by beams 18 (Fig. 2) in a vertical position, fix them from tilting and parallel to the first pair of racks install a second pair of racks in the same way. Pairs of racks are interconnected by shelves that are hung on hooks 4. Introduce into the holes 7 extensions (not shown) and diagonally squeeze the ends of the racks to the middle of the rack, install all racks in a vertical position and, if necessary, fasten them to the floor with anchors inserted into the holes floor and holes 15 of the lower supports of the uprights (Fig. 4).

When installing the rack, the end of each beam 18 (Fig. 3) is inserted into the opening s of the rack (Fig. 4), the surfaces of the beam 18 are tightly joined with the inner surfaces of the steps 6 of the rack, and each end of the beam 18 is placed in close contact with the inner surface 20 of the front wall 1 rack (Fig. 3). Next, the fastening elements 21 connect the side walls 2 and 3 of the racks with beams 18.

Installation on racks 1 of the first tier of the rack racks 1 racks of the second tier of the rack is provided (Fig. 6). In this case, the upper support 10 of each rack 1 of the lower tier is joined with the lower support 10 of the strut of the second tier, as shown in FIG. 6, and connect the indicated supports with fasteners, which are inserted into the compatible holes 15 of the mirroredly arranged buttressed supports 10.

During the operation of the rack, each rack experiences static loads from the action of the load on the shelves, as well as dynamic and shock loads during loading and unloading operations, while the rack works for bending from bending loads, as well as for crushing in the places of the shift of the rack relative to the floor 17 of the room . These loads are perceived by the support 10, its side walls 11-13, which eliminates the displacement of the rack relative to the floor. This significantly increases the strength of the rack covered on four sides in its lower and upper parts, the reliability of the connection of the rack with the floor, strengthens the end of the rack, reduces stress concentration at its ends, increases the resistance to collapse of the rack and bending in the most dangerous end zones.

Bending loads on the rack are more effectively absorbed by the profile made in accordance with FIG. 3, having stiffeners on each side wall and a stronger front wall 1 (without a plurality of holes weakening therein).

The execution form of the rack, the location of the flanges 8 on the outer sides of the side walls, the supports 10 at the ends of the rack, the location of the flat contact inner surfaces of the rack so that they are closely adjacent to the planes of the beams 18 and their ends, tightly adjacent to the even flat surfaces of the front walls 1, and also the implementation of the front wall 1 of the rack is flat (without grooves and a lot of holes in it) with the possibility of tight contact with it of the ends of the beams, significantly increase the resistance of the rack to bending and crushing, which ultimately allowed to increase stability of the rack, its reliability and safety of use in metal structures belonging to the dangerous category of storage equipment.
