CORNER GRID PROFILE

The utility model relates to the field of construction, in particular to the construction of profiles used as elements that strengthen the corners and faces of external walls to ensure high-quality performance of external, internal and heat-insulating plastering and puttying.

Known perforated corner profiles to strengthen the corners and faces of external walls (EP No. 324918, DE No. 3742319, DE No. 20020707U1).

Closest to the claimed utility model is a corner angle profile (DE No. 7923703).

The disadvantages of the known profile include the fact that in the manufacture of a profile of considerable length with the angular conjugation of the shelves decreases the mechanical strength of the part. The mesh shelves are made flat, which worsens the "adhesion of the plaster mortar with the metal elements of the mesh profile in comparison with the mesh design of the proposed profile.

The problem solved by the proposed utility model is to improve the characteristics of the corner profile due to the proposed aspect ratio of the profile elements (in cross section).

The problem is solved due to the fact that the angular equal-shelf net profile consists of two shelves connected by a transition section and oriented at an angle to each other, solid strip sections symmetrical with respect to the longitudinal axis of symmetry of the profile are made on each shelf, with a width of 30 to 50% of the shelf length parallel to which on each of the shelves symmetrical slots are made, located in a checkerboard pattern with a row offset by half a step

(half the length of the slot), forming after drawing a mesh structure with diamond-shaped cells.

The edges of the rhombuses are turned at an angle of up to 90 ° with respect to the plane of the bridge and give the surface of the grid a ribbed appearance.

The transition section at the junction of the shelves has two parallel walls, conjugated by a cylindrical surface convex to the outside of the profile. Shelves are located at an angle of 70-90 ° to each other. The distance between the parallel walls of the transition section is from 10 to 20% L - the total length of the shelf (from the top of the corner to the end of the shelf).

Profiles can be made of aluminum alloys or steel (galvanized or stainless).

The utility model is illustrated by drawings, which depict:

in FIG. 1 - main view of the profile;

in FIG. 2 is a section AA of FIG. 1;

in FIG. 3 is a view B of FIG. 2;

in FIG. 4 - connection node shelves profile.

A perforated mesh equal-profile profile has two shelves 1 and 2, oriented at an angle from 70 ° to 90 ° to each other, on each of which slots are formed along the profile length, symmetrical with respect to the longitudinal axis of the profile and with respect to solid strip sections 7 and 8, each of whose width is from 30 to 50% of the shelf length (shelf length from the top of the corner to the edge).

The slots after drawing form a mesh structure with diamond-shaped cells 3, and the edges of the rhombuses 9 are turned at an angle of up to 90 ° with respect to the jumper plane.

a convex outward profile and having a radius R of at least 2.0 mm. The distance between walls 4 and 5 is from 10 to 20% L - the total length of the shelf (from the top of the corner to the end of the shelf).

The transition section in combination with the solid strips 7 and 8 form a stiffener for a long profile part.

Profiles can be made of aluminum alloys or steel (galvanized or stainless).

In this case, the structural elements of the cross section of the angular mesh profile, the parameters of the mesh rhombuses are performed depending on the mechanical and technological characteristics of the selected material.

In the manufacture of plastering work, the proposed cross section of the angular mesh profile improves the mechanical strength of the connection of the particles of the solution filling the diamond cells with metal mesh construction elements.

The proposed angular mesh profile is also used in the production of puttying, having previously leveled the outer surface of the shelves.
