Description

BUILDING METAL PROFILE OF BOX

The utility model relates to the field of construction, namely to building metal profiles that are used to form the skeleton of suspended ceilings and wall cladding in buildings and structures.

It is known that currently for these purposes are widely used metal building profiles of the “Strong” type (hereinafter referred to as “Strong” profiles). A distinctive feature of these profiles is their manufacture from sheet material, the front and back sides (surfaces) of which are equally embossed (have the same relief pattern): on both sides of the sheet material there are many hollows and protrusions, each of the protrusions created by local plastic deformation of the sheet material leaving a corresponding cavity on its opposite side. This deformation is created by the molding tool, and its result is hardening (an increase in hardness due to hardening) and an increase in the effective thickness of the sheet material.

The closest technical solution to the claimed utility model is the well-known (RU, 87941, U1, IPC B21D13 / 04, published October 27, 2008, Fig. 15, 16 and p. 25 descriptions) box-shaped profile having shelves (edges) and the canvas separating shelves at a given distance, while on both sides or part of the surface of the sides of the shelves and the canvas there are rows of protrusions and depressions, and the protrusions on one surface correspond to depressions on the other opposite surface.

The main disadvantage of the known technical solution is the rounded (flattened) top of the protrusions / depressions of the relief pattern, which is a consequence of the fact that a tool with many teeth on its outer surface is used to form the sheet material, each (tooth) of which has a rounded shape and is in contact with the sheet rounded surface: the tooth-forming lateral surfaces protrude upward from the sides of the rectangular tooth base and smoothly (along a curve) rise to a common flattened vertex. This form of depressions / protrusions leads to excessive thinning of the material and a decrease in the effective contact area of the surface of the profiles with mating parts (in particular, with drywall boards). The problem to which the claimed utility model is directed is to increase the rigidity and strength of prefabricated buildings. The technical result obtained by the implementation of this utility model is to increase the contact area of the surfaces of the metal profile with the surfaces of the mating product (drywall or other plate) or part (for example, a different profile), which ensures their better fit to each other. The specified technical result is achieved due to the fact that the building metal profile is box-shaped, having shelves and a canvas separating the shelves at a given distance, where on both sides or part of the surfaces of the sides of the shelves and the canvas there are rows of protrusions and depressions, and the protrusions on one surface correspond to hollows on the opposite surface, the peaks of the protrusions parallel to the base of the protrusions are flat.

The presence of flat peaks at the protrusions increases the area (the plane has a larger area compared to the point contact of the rounded vertex) of the contact of the surfaces of the metal profile with a contacting surface: the working contact surface of any of the profile elements is formed by a multitude of flat vertices of the protrusions of the sheet material from which the profile is made.

The protrusions / depressions on the embossed surface of the profile may have a lateral surface in the form of a cylinder, a truncated cone, a truncated pyramid, a parallelepiped, a prism, etc. Accordingly, the cross-sectional shape of the protrusions / depressions can be rectangular, trapezoidal, and a flat top parallel to the base of the protrusion / depression can be round, oval, rectangular, in the form of a polyhedron, etc. The deformation of the initial material of the profile occurs more evenly and thinning of the material is minimal if the lateral surfaces of the protrusions / depressions have the shape of a truncated cone, each with a flat top in the shape of a circle. The indicated parameters of the protrusions / depressions are determined by the shape of the teeth of the tool used for knurling the embossed surface on the sheet material.

The protrusions / depressions on the surface of the profile can be arranged in straight and / or spiral rows and, as a rule, at the same distance from each other. The step (the repeated distance between the protrusions / depressions) depending on the thickness of the used sheet material of the profile can have a different value: a larger step is chosen when using a thicker material so that the metal does not thin during knurling, but a decrease in the step increases the area of plastic deformation due to the increase the density of the teeth of the knurling tool.

 The mutual arrangement of the protrusions and depressions on the surfaces of the sheet material may be such that the lines drawn along the surface of the sheet between adjacent rows of protrusions are not straight.

Depending on the purpose, the construction metal profiles of the claimed design are divided into ceiling, rails and rack.

Ceiling profiles have a C-shaped cross section and are used for the installation of drywall and other plates in the construction and repair of ceilings and walls in buildings and structures - they serve to form a frame of suspended ceilings and wall cladding. The ceiling profile is fastened to the supporting base (ceiling) using special suspensions, the main ones being a direct suspension and a suspension with a clip: the flanges (edges) of the ceiling profile shelves bent inward serve as an emphasis for installing the suspension with a clip, the direct suspension is mounted on the ceiling profile when help of self-tapping screws. Using special connectors, ceiling metal profiles paired with appropriate guide profiles allow mounting the frame of the required design with minimal time.

The guide profiles have a U-shaped cross-sectional shape and are used for the installation of frameworks for interior partitions, ceilings, facings and other structures based on plasterboard and other plates. The guide profile serves, as a rule, as a guide element for the ceiling and rack profiles of the corresponding size, as well as for the device of jumpers between them in the frameworks of partitions and claddings. Guide metal profiles are made with through holes in the fabric, which are designed to install dowels, which greatly facilitates the process of attaching the profile to the supporting base.

Rack profiles have a C-shaped cross-sectional shape and serve, as a rule, as vertical racks of frames designed for plasterboard partitions and claddings and other structures based on plasterboard and other plates. Rack profiles are mounted in tandem with the corresponding guide profiles in size; fastening the rack profile in the guide profile is done using self-tapping screws. As a rule, longitudinal grooves are made on the shelves of the rack profile, which increase its rigidity, and the central groove is also a reference point, both during the exact assembly of the frame and when installing drywall sheets. There are usually through holes on the surface of the web of the rack profile that allow installation of utilities inside partitions and claddings.

These building profiles can have various geometric dimensions - width, height, length, metal thickness and have additional stiffeners, grooves, grooves and holes of various shapes on the canvas or shelves.

To confirm the industrial feasibility of the claimed utility model with the achievement of the above technical result, a description is given of a specific, but not the only possible, design of the box-shaped guiding building metal profile (hereinafter referred to as the guiding building profile, profile).

The guiding construction profile (Fig. 2) with a U-shaped cross-sectional shape (box-shaped open type) has a web 1 separating the shelves 2 perpendicular to the web by a predetermined distance. The canvas has longitudinal rectangular grooves 3 located on both sides of the longitudinal axis of symmetry of the profile, formed at the stage of manufacturing the profile by rolling on roll forming lines. Grooves 3 are designed to increase the stiffness of the profile, and through holes 4 made along the longitudinal axis of the box between these grooves 3 are used to fasten this profile during construction and repair to the supporting structures.

The specified guide construction profile is made by rolling on roll-forming lines from sheet material, for example 08PS OTs, on both sides of which there are rows of protrusions 5 and depressions 6, and the protrusions on one surface correspond to depressions on the other (opposite) surface: under the protrusion on one side of the sheet material there is a hollow when viewed from the opposite side of the profile. The protrusions 5 and depressions 6 on the profile surfaces alternate, being at an equal distance from each other. The lateral surfaces of the protrusions 5 / depressions 6 have the shape of a truncated cone, the cross-sectional shape of each protrusion 5 / depressions 6 is a trapezoid, the vertex 7 located parallel to its base is flat and has a circular shape in plan.

A metal tape of a given width and thickness is installed on the uncoiler of the automatic roll forming line and then fed to the device with knurled rollers. The sheet material with the initial cross section is formed by passing it between a pair of knurled rollers (cylindrical rolls), each of which has many identical teeth on its surface, with each tooth having a truncated cone-shaped side surface formed integrally with its flat base and flat the top.

The tool used to form the protrusions ensures the flatness of the peaks of the protrusions. The presence on one of the rolling rollers of a plurality of protrusions (teeth) with flat vertices, each of which is in contact with the flat bottom of the corresponding depression on the reciprocal rolling roller, provides on the deformable tape receiving protrusions with flat vertices. That is, the embossed surface is formed by two identical rollers that are installed: one in the lower position, the second in the upper position so that the protrusion of the lower roller coincides with the depression of the upper roller and vice versa the protrusion of the upper roller corresponds to the depression of the lower.

After deformation (plastic deformation) of the tape, the tape is fed into the profile bending mill, where the profile is formed sequentially in the mill cages with all the necessary elements (stiffeners, radii, sizes, etc.). The necessary holes can be made both in the stands of the roll forming mill, and when cutting the profile with a stamp. The finished profile of measured length falls on the receiving table, is folded and packaged in pallets.
