The prototype of the present invention is the “Method for manufacturing metal structures with a roof” disclosed in the invention patent RU 2740652 C1 01/19/2021. According to this patent, the method of assembling a metal structure includes mounting the frame in the first stage. The frame is formed from the main vertical elements of the frame - end posts, which are made either composite, bolted together, or solid. Then tables and shelves are attached to the racks, to the end outer part or to the inside of the rack. After that, planks with carved patterned elements are installed, this part is installed horizontally between the end posts in the upper part. The design is completed by the roofing part, which is either one-, two-, or three-slope. In this case, end posts and roofing sheets are used to manufacture the roofing part. The roofing sheets are welded to the end posts at a given height, while the metal frame elements are cut on a plasma machine, the ribs are formed on a sheet bending machine, and the geometric shapes of the structure are achieved by welding. All of the above parts are connected in series using bolted connections. Using this technology, grill grates are made, which consist of two slats made of sheet steel with holes, while one side of each slate is bent 360°, so that the internal radius of the bend is equal to the radius of the rod, thereby forming a groove to the diameter of the rod, the other side of the planks is bent 90°, creating a shelf-limiter. The planks are connected to each other with a rod and each rod is welded to each plank on both sides.

However, the assembly and production of known structures has a number of disadvantages, namely, they have insufficient rigidity, have an integrally welded frame of the main structure, roof and roofing part or are partially dismountable, have large-sized parts and elements, have high costs for packaging and transportation of finished structures, and have a high cost and labor costs for manufacturing, do not have protection against injury to the end user during the operation of the structures.

The objective of the present invention is to eliminate the above disadvantages, namely to increase the rigidity of the structure, to produce a completely collapsible frameless structure and a roof with a roofing part, to eliminate large-sized parts and elements, to significantly reduce the cost of packaging and transportation of finished structures, to reduce the cost and labor costs for the manufacture and assembly of the structure , reduce the risk of injury to the end user during the operation of structures.

Disclosure of the invention.

The technical result consists in increasing the rigidity of the structure, manufacturing a completely collapsible roofing part of the roof, eliminating large-sized parts and elements from structures, significantly reducing the cost of packaging and transporting finished structures, reducing the cost and labor costs for manufacturing and assembling the structure, reducing the risk of injury to the end user in the process operation of structures.

The specified technical result is realized through the following assembly techniques from finished structural parts. The assembly of a metal structure includes mounting the frame at the first stage, while the main vertical part of the frame is the end posts, made of two elements of the main end post for fastening countertops, shelves and slats and the upper end post for fastening roofing sheets, the elements of the end post are fastened between are threaded connections and impart diagonal rigidity from the transverse rolling of the already assembled structures. If the dimensions of the rack elements do not exceed the dimensions of standard rolled sheet metal, then the elements are made in one piece; if the size of the rack elements exceeds the dimensions of standard rolled sheet metal, then the elements can be made of two parts and also fastened together with threaded connections. Then, tabletops and shelves from the inside of the rack are attached to each main lower end rack using threaded connections; additional tabletops can be attached to the outside of the rack if necessary. To the other side, opposite the surface of the main lower rack, additional legs are attached to the tabletops and shelves with threaded connections, thereby fastening all the listed parts into a single structure. One leg is attached as close as possible to the back side of the frame, the second at a certain distance from the first, the distance depends on the purpose of the finished structure or installed equipment, as well as on the shape of the countertops and shelves. Next, between the resulting two mirror halves of the future structure, additional central shelves or tabletops are installed, depending on the purpose of the structure. To prevent longitudinal rolling of the finished structure, a gusset with three holes is used, which is attached to threaded connections between additional legs with shelves, slats or table tops. Additional central shelves, strips or tabletops are attached to threaded connections to each additional leg and to each resulting half at a certain level in height according to the purpose of the finished structure. Also, between two additional legs, a support strip is attached either on one or both sides to threaded connections to form the installation height of the equipment. When attaching the bar on one side, equipment is installed in the formed place, the lower parts of which are at different heights (for example, a smoker, a stove for a cauldron with a barbecue in one piece, etc.), which rests on one side on the support bar, and on the other to the central shelf. When fastening the plank on both sides, equipment is installed in the formed place, the lower parts of which are at the same height (example barbecues, grills, grills, etc.), which in this case rests on both one and the other sides on an additional strip for installation in a horizontal position. Then, on the back side of the resulting structure in the upper part, a longitudinal strip is attached to threaded connections with a certain overlap on the main lower end posts, fastening them and increasing the longitudinal diagonal rigidity; this part is installed horizontally. The structure is completed by assembling the roof with the roofing part, which is made with one, two, three or five slopes, depending on the purpose of the structures. To assemble the roof with the roofing part, upper end posts and roofing sheets are used, to form the roof, each roofing sheet is attached to threaded connections or welded to the upper end posts at a given height from each other, the height is set when cutting the upper end posts depending on the required height and size of the finished product structure. Next, the assembled roof with the roofing part is installed on the main frame by bringing together the upper end of the main lower end post and the lower end of the upper end post and subsequently fastening it together with threaded connections. If barbecues and grills are installed in a metal structure, they are equipped with a grill grate, which is assembled from two strips made of sheet steel with holes for rods with a diameter of at least 4 mm. In this case, one side of each strip is bent by 360°, while the internal radius of the bend is equal to the radius of the rod, thereby forming a groove for the diameter of the rod, the other side of the planks is bent by 90° creating a shelf limiter. The planks are connected to each other by a rod and each rod is welded to each plank on both sides.

Implementation of the invention.

The design includes the main end vertical posts with carved patterned elements, which can be either composite and fastened together with threaded connections on large structures, or integral in smaller ones. Racks are the main vertical element for creating structures, their number depends on the size of the structure itself and on the size of the roof; the minimum number of main end racks used in structures is two. If it is necessary to have a roof in the structure, the number of main end posts and upper end posts is the same; if there is no need for a roof in the structure, then only the main end posts are used. When formed on a sheet bending machine, places of geometric shapes (in the form of an oval, semicircle, wave, stepped shapes, etc.) are achieved by welding strips, corners, the resulting ribs, in turn, also form a load-bearing frame. The entire structure is assembled with threaded connections, thanks to such a frameless, self-supporting structure, unlike integrally welded barbecue areas, gazebos, swings and other similar structures, there is no overlap of various rolled metal products on top of each other, resulting in overlap (for example, welding a sheet with an overlap onto a profile pipe , rod, square, etc.) and thereby creating an inaccessible connection for painting the finished frame, such places are a source of corrosion and subsequently the corrosion spreads to elements, parts and the structure as a whole. In our designs, the process of high-quality painting is much easier to carry out, thanks to the collapsible structure, each part can be placed in any convenient spatial position during the painting process. In our designs, due to the fact that all parts and elements are presented in volume, both with a small and large area, but at the same time with a sufficiently low height of each part of the structure, thereby reducing the volume of disassembled structures and, accordingly, reducing packaging costs and transportation.

In the design, tabletops and shelves are one of the main structural parts, which in turn create ease of use for the end user, additional structural rigidity, both in longitudinal and transverse rolling, and can bear a higher load. Tabletops and shelves are made both with and without carved patterned elements; it is also possible to embed a sink with a water tap into the tabletop for greater convenience when using structures as areas for cooking on fire, a barbecue area, a grill area, etc.

In the design, additional tabletops, both with and without carved patterned elements, are installed on the outside of the frame end on the main end vertical posts, when the surface area of the main tabletops is considered insufficient to operate the frame for its intended purpose, or the main tabletops are completely absent.

The structure is equipped with additional legs for the stability of tables, shelves and the frame as a whole, the legs are also used to form a niche, to unload the main end racks of the structure from the weight of heavy equipment in the form of barbecues, barbecues with fireboxes, smokers, grills, etc. In smaller structures, where the formation of niches for installing heavy equipment is not required and lighter equipment is installed in the form of barbecues, grills, cauldron ovens, etc., additional legs are not used. In this case, the load is distributed across the main end posts, when using tabletops, planks or support profiles using shelves, which in turn are sequentially attached to the threaded connections between the main end posts, and when using a support profile on each main end post. To form a niche for the installation of light equipment, limit strips are used, which in turn are attached through threaded connections to table tops, strips or to a supporting profile, depending on the purpose of the finished structure. Support profiles are used in pairs (two pieces each) in finished structures to form niches for installing equipment that has protruding parts or elements (for example, an ash drawer) in the lower part that do not allow installation of the equipment in the proper horizontal position and requires supports specifically for end sides of the equipment.

The roof with the roofing part is made of one-, two-, three-slope or more depending on the purpose of the structures and consists of upper end posts and roofing sheets. The main function of the roofing part is to protect it from direct sunlight and precipitation.

The design also uses a longitudinal strip with carved patterned elements, this part is installed horizontally between the end posts in the upper part for additional diagonal rigidity of the frame from longitudinal rolling, and also, depending on the design, when forming a niche for heavy equipment, forming seats (benches), etc.

All of the above parts are connected in series with threaded connections, thereby creating a rigid and durable structure.

When installing barbecues and grills into the structure, they are equipped with a grill grate. In this case, the grid is assembled from two strips made of sheet steel with holes, one side of each strip is bent 360 degrees (the internal bend radius is equal to the radius of the rod), thereby forming a groove for the diameter of the rod, the other side of the strips is bent 90 degrees to create a shelf The limiter, when installed ready-made on the top of the grill, limits the lateral movement along the width of the grill, while the grill grate can be freely shifted along the length both to the right and to the left. The planks are connected to each other by a rod and each rod is attached to each plank on both sides. Features of manufacturing design parts:

All structural parts are made from sheet metal with a thickness of 0.5 mm or more; for more massive structures, other types of rolled metal, parts and elements with complex cutting shapes or artistic elements, patterns, inscriptions, symbols, holes for threaded connections between parts can be used. themselves, etc., are cut on a laser, plasma or any other existing method of mechanized cutting with computer numerical control (CNC). At the same time, artistic elements, patterns, inscriptions, symbols, etc. (hereinafter referred to as patterns) can be cut onto any structural part, in a certain area, with a certain indentation along the perimeter of the part, without losing the strength of the part itself in the final result. When cutting parts, holes are also cut for threaded connecting the parts together, according to the intersection of the finished parts when assembling the finished structures. Then all parts are cleaned of slag and burrs, then all parts are bent on a sheet bending machine, along the edges of certain sides, according to the purpose of the part in the structures, thereby forming a stiffening rib on the parts, on straight and even sides (edges), in cross sections in the form l-shaped, u-shaped, c-shaped, z-shaped profiles, depending on the load and purpose of each specific part. The edges of the above listed profile forms can be bent 180 degrees into a fold, to give greater rigidity to the part; the fold prevents injury to the end user during the operation of the structures; bending into a fold is made depending on the purpose and installation location of the part in the structure frame. In places with complex shapes of parts (in the shape of an oval, semicircle, wave, bend, stepped shapes, etc.), a metal strip or corner is welded along the edge, perpendicular to the main plane of the part, which forms an L-shaped or U-shaped profile, respectively.

When manufacturing the main end posts (part 1), a stiffening rib is formed along the entire perimeter, except for the bottom edge; the stiffening rib is directed to the inner part of the assembled structure. The following is a view of the main area of the part in the established positions, in the finished and assembled structures. In the lower part of the main end post, a part of the area is cut out in the form of a U-shaped cutout, with a certain offset (distance) from the stiffener, depending on the size of the main end post. An indentation with a stiffener forms the main supports (legs) on each side, to which plates (heels) with a hole are subsequently welded in a horizontal position, to which, when assembling the structures, the main support heel (part 15) is attached to a threaded connection. If necessary, a stiffening rib is welded along the perimeter of the U-shaped cutout when the rigidity of the end post is insufficient. In other cases, the U-shaped cutout is strengthened by attaching a shelf or shelves to the main end post with threaded connections. A round or square rod or strip is welded to the main end post, with a certain distance from the top, between the ribs of the left and right sides of one part, thereby strengthening the structure of the main end post from twisting. This rod or strip (part 16) also serves as a kitchen rail (crossbar), for subsequent placement on it through hanging hooks of kitchen utensils, grilling equipment, etc.

A gusset with three holes (hereinafter referred to as the gusset, part 8), which is an isosceles triangle with rounded corners, cut from sheet metal, with three holes for threaded connections. When making gussets, stiffening ribs can be formed both along the long edge (side) and along the short edge (side) of the part, depending on the load and size of the structures and parts connected using the gusset.

Shelves (part 4), central shelves (part 6) and table tops (part 3), (hereinafter referred to as shelves and table tops), are shaped, overlooking the main area of the part, in the form of a rectangle, square, rectangle or square with a partially beveled corner , and the angle depends on the width of the main end post and the width of the niche formed for certain equipment. In the manufacture of shelves and tabletops, a stiffening rib is formed both along the entire perimeter and on the two opposite longest sides of the part; it is U-shaped in cross sections, depending on the size and purpose of the structure. In this case, the ribs are directed to the lower part of the already finished and assembled structure. If necessary, the height of the stiffener of shelves and tabletops can be increased along the entire length of a certain side of the part to accommodate additional holes. For fastening to threaded connections, without the use of gussets in assembling structures, to impart rigidity to the structure in longitudinal rolling, as well as for placing (cutting) patterns for decorating finished structures. If necessary, the height of the stiffener of shelves and tabletops can be increased only at the corners of the part, giving an elongated shape to the corners of the part to accommodate additional holes. For fastening to threaded connections, without the use of gussets in the assembly of structures, to impart rigidity to the structure in longitudinal rolling, without the possibility of placing (cutting out) patterns for decorating the finished structure. If necessary, to strengthen the surface of a shelf or tabletop, a rib is welded perpendicular to the main area from the bottom of the shelf or tabletop.

When manufacturing an additional table top (part 14), a stiffening rib is formed along three edges (sides) of the part except for the one that faces the main end post when assembling the finished structure. The additional tabletop in finished form is, when viewed from the main area of the part (top view), a square or rectangle. The view of the additional tabletop in its installed position, in a ready-made and assembled structure, both from the back and the front side, is a triangle with different legs. In this case, the triangle of the longer main area of the additional tabletop, at a distance sufficient for placing part of the part, with a shorter leg on the main end post for subsequent fastening to threaded connections, of both parts when assembling the finished structure.

During the manufacture of the strip (part 11), a stiffening rib is formed and is L-shaped or U-shaped in cross sections, depending on the load on this part. If necessary, the height of the bar stiffener can be increased along the entire length of a certain side of the part to accommodate additional holes. For fastening to threaded connections, without the use of gussets in assembling structures, to impart rigidity to the structure in longitudinal rolling, as well as for placing (cutting) patterns for decorating finished structures. If necessary, the height of the stiffening rib of the strips can be increased in height only at the corners of the part, giving an elongated shape to the corners of the part to accommodate additional holes. For fastening to threaded connections, without the use of gussets in the assembly of structures, to impart rigidity to the structure in longitudinal rolling, without the possibility of placing (cutting out) patterns for decorating the finished structure.

During the manufacture of the support profile (part 12), a stiffener is formed and is U-shaped in cross-section, the surface of which is of different widths. Gussets on both sides are attached to the ends of the resulting profile by welding, with two corners of the gusset at the welding points completely repeating the U-shaped profile, and the third corner is located outside the U-shaped profile. The support profile can also be made with the least amount of welding, by bending all the necessary edges (sides) of the part.

During the manufacture of the support (part 7) and limit strip (part 13), a stiffening rib is formed and is L-shaped in cross-section, while the width of the resulting surfaces is the same, and the length of one surface is greater on each side, by the width of the surface. The next stiffening rib is formed on both sides of the part, the surface of which is larger. In this case, I get the shape of the part in the form of a rectangular parallelepiped, without two rectangular elongated sides adjacent to each other. That is, a cross-sectional profile with an L-shape is capped at the ends by welding a square or triangular plate whose dimensions are equal to the width of the surfaces of the stiffeners.

When making a longitudinal strip (part 9), a stiffening rib is formed under the long edges (sides) and is U-shaped in cross section; patterns are placed (cut out) on the main area to decorate the finished structure.

When manufacturing an additional leg (part 5), a stiffening rib is formed and has an L-shaped cross-section, both with an equal bend flange and with different bend flanges. A support plate (heel) is welded at the bottom of the additional leg.

The peculiarity of manufacturing a non-demountable, frameless roof with a roofing part. When manufacturing a roof consisting of an upper end post and a sheet or sheets of roofing, a stiffening rib is formed in the upper end posts along the entire perimeter of the part (the same operations are performed as in the manufacture of other structural parts, listed in the specifics of manufacturing structural parts), except places where roofing sheets are welded to the upper end post. The stiffening rib on the upper end post is directed towards the inner part of the structure. When making a roofing sheet or sheets, if the roof has two, three slopes or more, an L-shaped profile is formed - bent 90 degrees using a sheet bending machine. To achieve the required rigidity of the roofing part in large structures, 180-degree folds can be formed into folds on the curved edges of the roofing sheets. Next, the roofing sheets are welded to the upper part of the upper end posts and to the stiffeners of the upper end posts. In this case, the bend of the roofing sheet and the edge of the upper end post are at the closest possible distance to create maximum rigidity of the finished roof with the roofing part. The distance between the upper end posts depends on the size of the structures and the overhang of roofing sheets at the end sides of the finished structure. The upper part of the upper end post has a curved shape - a radius, thereby forming a curved shape of the roof, in addition to the roofing sheets on the inside, reinforcements are welded in the required places in large structures, in the form of an L-shaped or U-shaped profile, the welded part of which repeat the shape of the upper part of the upper end post. The bend on the roofing sheet not only creates a stiffening rib, but also performs the function of drainage - ebb.

When making a roof with a gable roofing part, the slopes of which are directed in one direction, the roofing sheets are located at a certain height from each other with a certain overhang, thereby forming a longitudinal ventilation gap between the roofing parts. The overhang depends on the height of the upper part from each other in relation to the lower part of the roof, to prevent precipitation from getting under the roof.

When making a roof with a three-slope roofing part, the slopes of which are directed in different directions, the roofing sheets are located at a certain height from each other with a certain overhang, thereby forming a longitudinal ventilation gap between the roofing parts. The overhang depends on the height of the upper part from each other in relation to the lower part of the roof, to prevent precipitation from getting under the roof. In this case, the direction of the slope of the two lower parts of the roof is directed in opposite directions with respect to each other. The upper part of the roof is located with a certain overhang - overlapping both lower parts of the roof, thereby forming the ridge of the roof.

This roof structure and the roof as a whole create sufficient rigidity and at the same time obtain a self-supporting roof with a roof without additional reinforcements and frames, accordingly reducing the cost and labor costs for the manufacture of structures

Feature of manufacturing a collapsible roof with a stepped roofing part.

When manufacturing a roof with a collapsible roofing part, consisting of an upper end post (part 2) and a sheet or sheets of roofing (part 10), a stiffening rib is formed in the upper end posts along the entire perimeter of the part; the same operations are performed as in the manufacture of the rest structural parts listed in the specifics of manufacturing structural parts). On the upper end post, the stiffening ribs with their end side are directed perpendicular to the main area of the upper end post and directed into the inner part of the finished and assembled structure. The plane of the stiffening ribs on the upper part of the upper end post is given a stepped shape, with a certain inclination of each plane of the step both to the previous and to the subsequent plane, but the difference in the angle of inclination of each plane to each other is the same. The number of planes of the stiffeners depends on the number of roofing sheets, to which they are subsequently attached using threaded connections when assembling the finished structure. A stepped shape is also given to the roofing sheets, which are attached to threaded connections during the assembly of structures. On more massive roofs, to increase the rigidity of structures, a stiffening rib with a stepped shape is created in the places of fastening with the main area of the roofing sheet, a radius is created, directed with its convex side outward, and the given shape is, in turn, given to the roofing sheets along the entire length. To maintain the shape of the radius along the entire length on the roofing sheets, if necessary, reinforcements are welded on the inside in the required places, in the form of an L-shaped or U-shaped profile, the welded part of which follows the shape of the plane of the stiffener.

When making roofing sheets, an L-shaped profile is formed - bent 90 degrees using a sheet bending machine. To achieve the required rigidity of the roofing part in structures with a large and long roof, the distance between the bends on the roofing sheets is reduced, the height of the bend edge and the thickness of the sheet metal used on the curved edges of the roofing sheets are increased, 180-degree folds can be formed into a fold. On the roofing sheet or sheets located between the first lower and last upper roofing sheets, a folding rib is formed on the lower part of the roofing sheet to the bottom, on the upper part to the top, obtaining a Z-shape of the roofing sheet. And accordingly, the roofing sheets will repeat the stepped shape of the upper part of the upper end post, while on the first lower and last upper roofing sheet, the bends located on the edge of the roofing part from the back and front sides are bent upward to form an ebb, or downward for unhindered rolling along the finished roof of atmospheric precipitation. When assembling a roof from ready-made products and parts, roofing sheets are attached using threaded connections to the upper part of the upper end posts; at the beginning of assembly, the first lower sheet is installed, then the next one, which in turn covers with a lower bend, the upper bend of the first lower sheet, and the subsequent sheet overlaps the upper bend of the previous sheet with its lower bend, etc. The roof assembly is completed by installing the last top roofing sheet, which in turn overlaps the upper bend of the previous sheet with its lower bend. To increase the rigidity and strength of the roofing part of the roof, the roofing sheets are connected with threaded connections to each other at the intersection of the bends. The distance between the upper end posts depends on the size of the structures and the overhang of roofing sheets at the end sides of the finished structure. On more massive roofs, to increase the rigidity of structures, the upper part of the upper end post has a curved shape - a radius, thereby forming a curved shape of the roof, in addition to the roofing sheets on the inside, reinforcements are welded in the necessary places in large structures, in the form of an L-shaped or a U-shaped profile, the welded part of which repeats the shape of the upper part of the upper end post.

When manufacturing a roof with a single-pitched roofing part (product 1, 2, 3), while the roofing part can consist of either one or two or more roofing sheets, the roofing sheets are arranged with overlapping bends, without forming a longitudinal ventilation gap. This type of roof is used in relatively small structures with a small roof area

When making a roof with two roofing parts (product 4), the roofing parts can consist of either one or two or more roofing sheets, the slopes of which are directed in one direction. The roofing parts are located at a certain height from each other with a certain overhang; the height is set during the manufacture of the upper end post, thereby forming a longitudinal ventilation gap between the roofing parts. The overhang depends on the height of the upper part from each other in relation to the lower part of the roof, to prevent precipitation from getting under the roof.

When making a roof with three roofing parts, the roofing parts can consist of either one or two or more roofing sheets, the slopes of which are directed in different directions, the roofing parts are located at a certain height from each other with a certain overhang. The height is set during the manufacture of the upper end post, thereby forming a longitudinal ventilation gap between the roofing parts. The overhang depends on the height of the upper part from each other in relation to the lower part of the roof, to prevent precipitation from getting under the roof. In this case, the direction of the slope of the two lower parts of the roof is directed in opposite directions with respect to each other. The upper part of the roof is located with a certain overhang - overlapping both lower parts of the roof, thereby forming the ridge of the roof. This type of roofing is used to form structures similar to gazebos, canopies, etc.

Application and purpose of structures: This method of manufacturing structures can be used in the manufacture of: barbecue complexes with a roof; or barbecue areas with a roof; or grill stations with roofs; or grill stations with roofs, grill complexes with roofs; or stands with tables for an oven for a cauldron, barbecue, smoker, grill; or swing; or gazebos; or benches; or awnings; or tables; or fencing; or fences for graves; or fences; or decorative fences; or racks, etc.

The dimensions of the structures can be of any size and shape and purpose; the thickness of the material used increases in relation to the size and purpose of the structures.

After manufacturing, structures can be painted with any of the known painting methods and any type of paint, depending on the application of the structures.
