Description

This utility model relates primarily to means of storing cargo of small mass. The utility model is intended for use in the construction of lightweight metal shelving. In this regard, the shelf is designed for its use in the construction of light racks with shelves of increased strength.

A shelf for storage racks is known from the Internet, containing the upper wall, side walls and means for connecting the side walls to the racks of racks (Warehouse Rack MKF, Yandex, Metal Plant. Storage Racks MKF, 2008. Storage Racks MKF Series, Yandex, metalcity, 30.05. 2014).

Shelf racks are also known from the patent documentation, each of which contains a top and side walls, as well as means for connecting shelves to racks (KR 201400006410 U, 01/29/2014. US 2014175036 A1, 06/26/2014. DE 202013101956 U1, 05/15/2013. KR 101217812 B1, 01/01/2013. MY123787 A, 06/30/2006. US 2011278251 A1, 11/17/2011. KR 20100001317 U, 02/08/2010. SI 123019 A, 10/29/2010.

In said patent RU 109384 U1, a shelf for light shelving comprises an upper wall, lateral longitudinal walls and lateral transverse walls, while the walls are equipped with stiffeners. This shelf has a box-shaped complex shape due to the presence of an additional corrugated sheet located under the upper wall of the shelf along its entire width and connected to the upper wall. The corrugated sheet, in fact, serves as a reinforcing element, solid stiffeners located under the upper wall, along its entire width and length.

Shelves made in accordance with the prototype have a relatively large metal consumption, as well as a relatively large thickness due to the presence of a corrugated sheet. When transporting packages of such shelves, they occupy a relatively large volume. Moreover, in the case of stress concentration on the side walls of the shelf, they do not sufficiently prevent deformation of the shelf, both in its working position and in the transport position when the shelves are transported in packages.

The closest shelf to the shelf presented in this description is a shelf containing a top wall, lateral longitudinal and transverse walls of a parallelogram having two diagonals, with gaps formed in each corner zone of the shelf between the side walls, in the corner zones located on the same diagonal of the shelf , two flanges are made mirror-oriented, which are a continuation of the side walls, and two other corner flanges are located on the other diagonal of the flange. flanges, which are a continuation of other side walls, with a flange made in each flange combined with a hole made in the transverse wall of the flange adjacent to flanging, each flange in its pre-mounting position is bent inside the flange and is located at an oblique angle to the longitudinal wall adjacent to it, at each longitudinal wall and one transverse wall have a flange in the form of a flange, and one transverse wall is made without a shelf. Each flanging is bent with respect to the plane of its wall at an angle of 90 °. Each gap has a height equal to the height of the side wall. Each hole of the side wall is compatible with the hole of the rack rack in the working position of the rack, and in this position of the shelf in the hole of each flanging of the longitudinal wall, in the hole of the transverse wall of the shelf, as well as in the hole of the rack, there is a fastener. In the transport position, the flanges of the side walls are located at an oblique angle to the longitudinal walls, and in the working position they are located at right angles to the side walls and overlap to the transverse side walls (RU 162600 U1, 06.20.2016 - prototype).

The shelf shelf presented in this description of the utility model has common features with the prototype, namely that each of them contains an upper wall, lateral longitudinal and transverse walls, gaps are formed in each corner zone of the shelf between the side walls, each longitudinal side wall has ends flanges, which are a continuation of the side walls, in each flanging, a hole is made that is compatible with the hole made in the transverse wall of the shelf adjacent to the flanging, each obturation in its pre-assembly part the decomposition is bent inward shelves and disposed at an oblique angle to the adjacent longitudinal wall with it.

When using racks with shelves made in accordance with the prototype, there is a bending of the shelves during the operation of the rack from the concentration of deforming stresses on the shelf in its working position. When the shelves are delivered to the consumer, there is a danger of their damage from shock loads acting on the shelves during their loading and unloading.

The technical result of the utility model is to reduce the concentration of deforming stresses on the shelf in its working position and during transportation by packages.

The technical result is obtained by a shelf of a rack containing an upper wall, lateral longitudinal and transverse walls, gaps are formed in each corner zone of the shelf between the side walls, each longitudinal side wall has flanges at the ends that are an extension of the side walls, in each flange a hole is made that is compatible with the hole made in the transverse wall of the shelf adjacent to the flanging, each obortka in its pre-mounting position is bent inside the shelf and is located at an oblique angle to the longitudinally adjacent to it wall, and the shelf on its lower side is equipped with a longitudinal stiffener with flanges on the sides connected to the upper wall of the shelf along its entire length, each end of the longitudinal stiffener is connected to an adjacent transverse wall of the shelf, and on the lower side, the longitudinal stiffener has a lower a flat surface for the interaction of the ribs with a similar surface of the longitudinal stiffening ribs of another shelf when they are connected in a package.

The height of the stiffeners is less than the height of each side wall.

The stiffener in cross section has a trapezoidal shape and its lower flat surface is facing away from the shelf.

In FIG. 2 - shelf angle, bottom view, fragment.

In FIG. 3 - angle of the shelf in the position of its fixation on the rack rack bolted connection, bottom view, fragment.

In FIG. 4 - view of the shelf from below.

In FIG. 5 - a pair of shelves connected in a package for their transportation in the cross section of the package.

The shelf of the rack contains the upper wall 1 (Fig. 1), the lateral longitudinal walls 2 and 3, and the lateral transverse walls 4 and 5. The shelf is made in the form of a rectangular-shaped box open at the bottom. To the upper wall 1 from its inner side along the axis of symmetry in the longitudinal direction of the shelf is connected by an integral connection a stiffener 6 made of a metal sheet. The rib has a trapezoidal cross-sectional shape and longitudinal flanges 7 located along the longitudinal edges. Flanging ribs are connected to the upper wall 1 of the shelf by the above connection. Each end of the stiffening ribs 6 is connected to the corresponding transverse wall 3 or 4 of the shelf.

In the manufacture of lateral transverse walls 4 and 5, the transverse ends of the workpiece are first flattened (bent 180 °), then the double sheet is bent at a right angle. In this case, reinforced side walls 4 and 5 are obtained as shown in FIG. 2 and 3. Such a manufacture of a shelf reduces metal waste during its cutting, energy and labor costs for the formation of the longitudinal side and transverse walls of the shelf.

The stiffening rib 6 is made separately from the upper wall of the shelf and is connected to it along the entire length of the upper wall 1. The thickness of the stiffening rib 6 is 2-3 mm less than half the thickness of the shelf. The presence of gaps 9 between the transverse walls 3 and 4 of the shelf and the flanges 8 at the ends of the longitudinal walls 2 and 3 make it possible to minimize the thickness of the stack of two shelves (Fig. 5) by placing the transverse faces of one shelf in the indicated gaps 9 of the adjacent shelf when they are shifted relative to each other in the longitudinal (by the thickness of the transverse faces of the shelf) direction and offset in the transverse (by the width of the longitudinal faces of the shelf) direction. After such a combination of two shelves, their upper walls 1 acquire additional rigidity, which also reduces the possibility of deformation of the shelves during their transportation, including loading and unloading operations, in which significant local impact loads are possible.

Flanges 8 made at the ends of the longitudinal side walls 2 and 3, which are a continuation of these walls, in the transport position of the shelves are bent at an acute angle in the opposite direction with respect to the longitudinal walls 2 and 3 (Fig. 2) with the formation of a gap 9 between adjacent lateral and transverse the walls.

In each flange 8 and along the edges of the adjacent lateral transverse wall 4 and 5, compatible holes 10 and 11 are made for the fastener for connecting the shelf to the rack rack.

Before assembling the rack, the flanges 8 are bent to a right angle with respect to the longitudinal walls 2 and 3 until they touch the lateral transverse walls 4 and 5 (Fig. 3), while the holes 10 and 11 are aligned.

When fixing the shelves to the racks 12 of the rack (Fig. 3) using bolted joints, the latter reliably press the flanges of the 8 shelves at all four corners to the transverse walls 4 and 5 of the shelf, forming a closed loop from the side walls 2-5 around the entire perimeter of the shelf, which eliminates individual deformations of the longitudinal and transverse walls 2-5, thereby increasing the strength characteristics of the shelf as a whole.

The flanges 7 of the slider located along the stiffening rib 6 (Fig. 5), tightly connected to the upper wall 1 of the shelf, reduce the concentration of stresses in the connection, while the presence of a longitudinal stiffening rib 6 makes it possible to increase the permissible load on the shelf during operation of the rack, as well as reduce local deflection shelves in its center. The stiffener 6 has a dual purpose: it increases the resistance of the shelf to bending along its length and prevents the pair of shelves from moving when they are connected to each other in a package with the goal of delivery to the consumer, including loading, transportation and unloading. This restriction of movement is achieved by abutting the rib 6 of one shelf to the rib 6 of another shelf when they are connected to the bag as shown in FIG. 5. For this, the stiffener 6 of one upper shelf has a lower flat surface that interacts through an elastic gasket 13 (Fig. 5) with a similar surface of the stiffener of the lower shelf when two shelves are connected in a package.

The shelf works as follows. After the shelves are made, they are packaged in pairs as shown in FIG. 5. When stacking shelves insert one shelf into another shelf so that the transverse side walls 4 and 5 of one shelf are located in the corner grooves 9 of the other shelf (Fig. 4). In this position, the ribs 6 of both shelves abut against each other with their flat surfaces through an elastic gasket 13 (Fig. 5). With this position of the ribs 6, crushing of the upper walls 1 from external loads is excluded. During the packaging of shelves, the pairs of shelves packaged by the indicated method are folded with the same package of the next pair of shelves, wrapped with packaging material and in this form the shelves are delivered to the installation site of the shelves.

At the place of installation of the shelves at the consumer, each shelf is removed from the bundle, the flanges of the 8 shelves are bent over all four corners to the design working position at right angles to their lateral longitudinal walls 2 and 3 (Fig. 3). Next, combine the hole 10 of each flange 8 with the hole 11 of the transverse wall, while controlling the alignment of the holes of the double sheet on the transverse walls with the corresponding holes of the racks of the rack 12, followed by fixing the assembled nodes using bolted connections. Similarly, connect other parts of the shelf with the corresponding walls of the racks of the rack.

If necessary, in this way, other shelves located on the racks in a tier are connected to the racks of the rack. After connecting the shelf to the racks, one shelf or several shelves together with the racks form a rigid structure, as a result, the shelf under load works as a unit with the racks, while the longitudinal and transverse bending forces are distributed evenly throughout the shelf. In operation, the load from the walls of the shelf is transmitted through the fasteners to the racks, while the load is also perceived by the stiffener 6 and is more evenly distributed over the entire power circuit of the shelf.
