Description

The utility model relates to the exhibition, trade equipment, namely, to the metal shelves and is designed to house exhibits, as well as a variety of products of trade enterprises.

There are many shelves, details of which: racks, rear panels, overhead shelves are connected to each other by different types of fasteners. As a rule, the racks include several racks located at the corners of the rack, on which, with different vertical distances, one or several horizontal overhead shelves are fixed, items and / or bulk goods are stored on these shelves, for example, according to RF patent No. 2337599 public 10.11.2008 Bull. №31.

The disadvantage of this design is a significant intensity of the rack, which ultimately increases its cost.

The closest technical solution adopted for the prototype, is the rack, published on the website: https://ozm.ru/v3-stellazh-pristennyy.html.

This metal shelving design contains at least two vertical posts made of sheet metal with a rectangular horizontal projection forming the inner hollow space and having rectangular shaped rectangular-shaped nests located in the form of a spatial grid on its front and rear side, shelves made of sheet metal , each of which is a flat rectangular-shaped supporting plate with flared planes along the long and short sides, having an element Stiffeners made in the form of bent sections of sheet metal, the horizontal ends of which are welded to the inner horizontal surface of the shelf, panels connecting the racks to each other, brackets installed in slotted sockets of the racks on which the stiffeners of the shelves rest.

Shelves allow you to equip stores of various formats - "convenience store", "discounter", "supermarket". The versatility of the shelving design is the ability to create both wall (one-sided) and island (two-sided) shelving options using the same parts.

The permissible load-carrying capacity of the wall sections of the racks with a distributed load is 640 kg. Allowable loads for mounted shelves vary depending on the size and location on the rack - from 90 to 160 kg, and on basic shelves - from 180 to 240 kg. The use of a fixing system for racks to the wall - metal corners, anchors, brackets braces increases the maximum allowable load on the wall rack to 1000 kg per section. The use of reinforced brackets allows you to increase the allowable load on the hinged shelves up to 240 kg. Wall reinforced racks with an additional front desk can withstand loads up to 1500 kg. on section.

Shelf racks have a closed profile and a combined point - continuous seam along the entire length, this improves the appearance and increases the reliability of the whole structure. In this case, the manufacture of racks of rolled products allows the use of steel grades with higher strength characteristics than in the manufacture of pipes. The brackets have additional stiffeners and can be installed in three different positions, which improves the view of the product.

For the calculation of heavier goods reinforced brackets with additional hooks are used. The shelves are solid and have 12 bends in the front and back, each of which is a stiffener. In addition, reinforcements are also welded to each shelf, also providing high load-carrying capacity.

A significant disadvantage of this metal shelving design, as well as analogs, is its increased metal content due to the use of increased thickness sheet metal to ensure the strength and rigidity of the shelving design. The introduction of a number of design solutions reflected in the utility model into the rack structure allows preserving, and in other cases, increasing the load capacity, strength and rigidity of the rack structure while reducing metal consumption in comparison with known samples.

The task of the utility model is to reduce the metal construction of the metal rack.

The technical result of the utility model is to reduce the metal construction of the metal rack.

формы.The technical result is achieved due to the fact that a metal rack containing at least two vertical posts made of sheet metal with a rectangular horizontal projection forming the inner hollow space and having rectangular shaped slotted sockets arranged in the form of a spatial grid on its front and back side, shelves, made of sheet metal, each of which is a flat supporting plate of rectangular shape in plan with flared along the long and short sides, having stiffeners, made in the form of curved sheet metal profiles, the horizontal ends of which are welded to the inner horizontal surface of the shelf, panels connecting the racks to each other, brackets installed in slot-like sockets of the racks on which the stiffeners of the shelves rest, according to the useful the model sheet metal thickness from which the shelves are made is from 0.35 mm to 0.55 mm, and the thickness of the metal sheet from which the stiffeners are made has a thickness of at least 0.6 mm, while The long long side of the shelf and the long long side of the shelf along its entire length are made with an inclined figured bend with reverse figured bend facing upwards, rolling onto the horizontal plane of the shelf and fixed to the inside of the plate by contact welding, forming closed areas in cross section stiffeners are made in the form

forms.

замкнутые площади 17, 18, при этом элементы жесткости 10 выполнены в виде формы, а толщина листа металла, из которых они выполнены, превышает толщину листа металла, из которой выполнены полки 6.The metal rack contains at least two vertical posts 1 made of sheet metal with a rectangular horizontal projection forming the inner hollow space 2 and having slotted nests 3 of rectangular shape arranged in the form of a spatial grid on its front 4 and rear 5 side. Shelves 6 of the metal rack are made of sheet metal, each of which is a flat supporting plate of rectangular shape in plan with flanging 7 along the long 8 and short 9 sides, having stiffeners 10 made in the form of bent sheet metal, the horizontal ends 11 of which are welded to the inner horizontal surface 12 of the shelf 6. The metal rack has panels 13 connecting the racks 1 to each other. The metal rack has brackets 14 installed in slotted sockets of 3 racks, on which stiffeners of 10 shelves 6 rest. New in the utility model is that from the front long side of the shelf, and from the back long side of the shelf, along its entire length, it is inclined figured bend 15 with reverse figured bend turned upward 16, rolling onto the horizontal plane of the shelf 6 and fastening to the inner side of the plate by contact welding, forming shelf 6 in cross section

closed areas 17, 18, while the stiffening elements 10 are made in the form, and the thickness of the metal sheet from which they are made, exceeds the thickness of the metal sheet from which the shelves 6 are made.

The ends of the rear panels have 90 ° bends and are equipped with three hooks 19 on each side for attachment to the uprights 1.

формы, а толщина листа металла Н, из которых они выполнены, превышает толщину листа металла h (см. фиг. 9), из которой выполнены полки 6. Это позволяет снизить металлоемкость полки до 42% без снижения прочности и жесткости стеллажа. Обычно, при производстве полок для достижения необходимой грузовой способности, прочности и жесткости стеллажа применяется листовой металл толщиной не менее 0,6 мм, из которого также выполнены и элементы жесткости полки. Но благодаря внедренным конструктивным особенностям полки, удалось сохранить те же параметры грузовой способности, прочности и жесткости стеллажа, снизив металлоемкость полок, применяя листовой металл для их изготовления толщиной от 0,35 мм до 0,55 мм, что доказано расчетным и опытным путем.The brackets 14 are mounted on the vertical bearing racks 1 using three-position hooks 20 with the ability to change position relative to the horizontal plane. Feature of the design is that the stiffening elements 10 are made in the form

forms, and the thickness of the metal sheet H, of which they are made, exceeds the thickness of the metal sheet h (see Fig. 9), from which the shelves 6 are made. This allows reducing the metal consumption of the shelf by up to 42% without reducing the strength and rigidity of the rack. Usually, in the production of shelves to achieve the required cargo capacity, strength and rigidity of the rack, sheet metal with a thickness of at least 0.6 mm is used, from which the stiffeners of the shelf are also made. But thanks to the embedded design features of the shelf, it was possible to retain the same parameters of cargo capacity, strength and rigidity of the rack, reducing the metal intensity of the shelves, using sheet metal for their manufacture from 0.35 mm to 0.55 mm thick, which is proved by calculation and experimentally.

Rack mounting and assembly sequence.

The assembly of the rack is carried out directly at the place of its operation.

When installing shelving the floors should be flat and horizontal. Permissible surface slope - no more than 2 mm at a length of 1 m.

Dragging an already assembled rack is not allowed.

With the required rearrangement of the rack, you must first disassemble the rack into its constituent elements.

Installation of the rack should be carried out by workers (at least 2 people) with appropriate skills.

At installation it is necessary to use the following tools:

- mall (rubber or wood);

- open-end wrench 14 mm .;

- level of construction L = 1-1.2 m.

Insert the base into the corresponding grooves of the rack and send the base all the way down, for a tight connection, tap the base with a mallet.

Install the adjusting supports on the base, screwing them approximately to the middle of the threaded part to be able to further adjust the rack, the size of the visible thread will be 15-20 mm.

The installation of the panels is carried out from below - upwards, at the same time, the three hooks of the 19 panels must completely go into the slotted sockets of the racks.

Install on the base 21 the appropriate regiment. Install the brackets in the rack at the required level, put the corresponding shelves on the brackets.

For correct installation of the rack, it is necessary to adjust the screw supports 22 so that the racks are installed vertically and the bases 21 are on the same horizontal level.

Shelves should be installed strictly on the corresponding brackets or bases and the width should not exceed the length of the base or bracket.

The industrial applicability of the metal rack is obvious. The production of the proposed rack is carried out with the help of specialized equipment including:

- press brakes;

- axis-turret presses;

- laser cutting systems;

- crank presses (stamping);

- resistance welding machines;

- line of longitudinal-transverse cutting of coils;

- automatic painting lines.

Manufactured prototype proved the achievement of the task.
