WALL PANEL FRAME Russian patent published in 2024 - IPC E04C2/38 E04C3/07 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular to the structure of wall panels based on metal thermal profiles for prefabricated buildings, as well as for repair of destroyed wall elements of various structures. Frame of the wall panel is made in the form of a rectangular frame, which includes interconnected building elements in the form of U-shaped plastically deformed, bent or rolled metal profiles with longitudinal perforated walls, including staggered thermal holes, and side shelves. One part of U-shaped plastically deformed, bent or rolled metal profiles of building elements is made with convex longitudinal walls with formation in section of isosceles trapezoidal tenon with a smaller base outward, on which thermal holes are made in the form of cutouts with flanges directed inside the profile. Other part of metal profiles is made with concave longitudinal walls with formation in the section of an isosceles trapezoidal slot with a smaller base inward, on which there are thermal holes made in the form of cutouts with flanges directed outside the profile. Building elements with convex longitudinal walls of metal profiles, forming in cross-section trapezoidal tenons with smaller bases directed outward, and construction elements with concave longitudinal walls of metal profiles, forming in cross-section trapezoidal slots with smaller bases directed inwards, are located in frame opposite to each other or in pairs in series one after another, and connection of metal profiles to each other is made by means of contact of end sections of their side shelves.

EFFECT: fabricable frames of wall panels are characterized by strength, spatial stability of shape and operational reliability, which is transferred to products and structures created using them.
