METAL FRAME BUILDING Russian patent published in 2023 - IPC E04B1/343 

FIELD: construction.

SUBSTANCE: metal frame consists of the lower and the upper base connected by posts. The profile of the lower base is made in the form of vertical and horizontal walls connected at right angles, while at the end of the horizontal wall there is a vertical extension directed upward, and at the end of the vertical wall there is a U-shaped niche formed by a vertical wall, a base perpendicular to the vertical wall and directed to the right, and the vertical wall of a U-shaped niche perpendicular to the base. The profile of the upper base is made in the form of vertical and horizontal walls connected at right angles, while at the end of the horizontal wall there is a U-shaped niche formed by a horizontal wall, a base perpendicular to the horizontal wall and directed upward, and a horizontal wall of a U-shaped niche perpendicular to the base. At the end of the vertical wall, there is a U-shaped niche formed by a vertical wall, a base perpendicular to the vertical wall and directed to the right, and a vertical wall of the U-shaped niche perpendicular to the base. The profile of the rack is made in the form of vertical and horizontal walls connected at right angles, while at the end of the vertical wall there is a U-shaped niche formed by a vertical wall, a base perpendicular to the vertical wall and directed to the right, and a vertical wall of a U-shaped niche perpendicular to the base. At the end of the horizontal wall there is a U-shaped niche formed by a horizontal wall, a base perpendicular to the horizontal wall and directed downward, and a horizontal wall of the U-shaped niche perpendicular to the base.

EFFECT: improved the reliability of fixation of frame elements.
